1 FNP II Final Exam Study Guide: Behavioral: objectives : how affect individuals, S/S behavioral disorders across the lifespan, screening tools, management, acute distress or suicide, recognising need for referral Autism Spectrum Disorder: BURNS chapter 20 zola. Delay and deviance in development of social skills, communication and cognitive skills ● Diagnostic Criteria: ○ ○ ○ Deficits in social communication and interaction across multiple contexts Restrictive, repetitive patterns of behaviors, interests, and activities. A total of more than 6 items from the following criteria with at least 2 of them from criterion 1 and one each from criteria 2 and 3: 1. Qualitative impairment in social interaction as manifested by at least 2 of the following: ● Marked impairment in the use of multiple nonverbal behaviors, such as eye-to-eye gaze, facial expression, body posture, and gestures to regulate social interaction. ● Failure to develop peer relationships appropriate to developmental level. ● Lack of spontaneous seeking to share enjoyment, interests, or achievements with other people (lack of showing, bringing, or pointing out objects of interest). 2. Qualitative impairment in communication as manifested by at least 1 of the following: ● Delay in or total lack of development of spoken language (not accompanied by an attempt to compensate through alternative modes of communication, such as gesture or mime). ● In individuals with adequate speech, marked impairment in the ability to initiate or sustain a conversation. ● Stereotyped and repetitive use of language or idiosyncratic language. ● Lack of varied, spontaneous make-believe play or social imitative play appropriate to developmental level. 3. Restricted, repetitive, and stereotyped patterns of behavior, interests, and activities as manifested by at least 1 of the following: ● Encompassing preoccupation with one or more stereotyped and restricted patterns of interest that is abnormal either in intensity or focus. ● Apparently inflexible adherence to specific, nonfunctional routines or rituals. 1 2 ● ○ ○ Stereotyped and repetitive motor mannerisms (hand, or finger flapping or twisting, or complex whole-body movements). ● Persistent preoccupation with parts of objects. Delayed/abnormal functioning in at least 1 of the following areas with onset before 3 y.o. ● Social interaction ● Language as used in social communication ● Symbolic or imaginative play Disturbance not better accounted for by Rett d/o or childhood disintegrative d/o. ● Behaviors Indicative of ASD: ○ ○ Problems with social interactions, communication, and language skills show by their unusual ways of relating to people, objects, and events. Abnormal responses to sensory stimuli, usually sound; and restricted, repetitive, or stereotyped behaviors and echolalic speech. Language delays, lack of social relatedness, severe behavior problems. Expressive language is delayed, repetition of words/phrases, decreased eye contact, detached, repetitive movements. Insistent on routines. ● When to Refer: ○ ○ Screening is recommended by the AAP at 18 & 24 months. If there is a concern that a child has Autism, referral for a comprehensive diagnostic assessment should be done by a multidisciplinary team. Be sure that you understand what the core domains of ASD are and be able to identify the diagnostic criteria for ASD ADHD: BURNS chapt 20 Affect cognitive, educational, behavioral, emotional, social functioning s/s: inattention, hyperactivity, impulsivity in at least 2 settings: home, school or work Impairment in social, academic or occupational functioning ● THREE TYPES OF ADHD; ● ● ● 314.01 (F90.2) Combined presentation: ○ If both Criterion A1 (inattention) and Criterion A2 (hyperactivity-impulsivity) are met for the past 6 months. 314.00 (F90.0) Predominantly inattentive presentation: ○ If Criterion A1 (inattention) is met but Criterion A2 (hyperactivity-impulsivity) is not met for the past 6 months. 314.01 (F90.1) Predominantly hyperactive/impulsive presentation: ○ If Criterion A2 (hyperactivity-impulsivity) is met and Criterion A1 (inattention) is not met for the past 6 months”. CLASSIFY CURRENT SEVERITY: ● “Specify Mild”: Few, if any, symptoms in excess of those required to make the diagnosis are present, and symptoms result in no more than minor impairments in social or occupational functioning. 2 3 ● Moderate: Symptoms or functional impairment between “mild” and “severe” are present ● Severe: Many symptoms in excess of those required to make the diagnosis, or several symptoms that are particularly severe, are present, or the symptoms result in marked impairment in social or occupational functioning”. ● Prevalence of each: ○ ○ ○ ADHD, combined type: accounts for majority of ADHD cases ADHD, predominantly inattentive: accounts for one-third of ADHD cases ADHD, predominantly hyperactive/ impulsive: accounts for the fewest ADHD cases ATTENTION-DEFICIT/HYPERACTIVITY DISORDER DSM V Diagnostic Criteria: - “A persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development”. Prevalence: Occurs in 5% of children (all cultures) and 2.5% of adults IMPORTANT TO NOTE- The symptoms are not clearly due to something else! Are they bored? Do they not understand directions and that’s why they aren’t doing it? - Ages 4 and 18 years old. (really can’t distinguish before 4). - Might notice when the child is older because their grades are showing for it - Information must be from 2 different environments (parent, teacher, other). - Comorbidities should be addressed; regarding emotional and behavioral, developmental and physical. - Conduct comprehensive medical, developmental, family and educational history. SIGNS MAY BE MINIMAL OR ABSENT - Frequent positive reinforcement - Well supervised: are they helicoptering and catching the bad behavior before it starts? This is sometimes why the behavior is totally different at home - NEW setting (of course they are behaving and aren’t showing their problem behaviors yet) - Interested : again, bored? - Electronics: makes diagnosis hard - Office visit: may not see it here because of the 1:1 attention RISK AND PROGNOSTIC FACTORS - Possible traits: adventure seeking and negative emotions - Environmental: LBF, child abuse, toxins like lead - Genetic : White children > more freq diagnosed, strong genetic links in families - Culture - Gender: boys> girls for ADHD 3 4 DIFFERENTIAL DIAGNOSIS - Oppositional defiant disorder - Intermittent explosive disorder: extreme behaviors, no issues with attention. - > pts with the above 2 need psych help - Other neurodevelopmental disorders - Specific learning disorder - Intellectual disability (intellectual developmental disorder) - Autism spectrum disorder (ADHD and Autism) – may be inattentive and have social dysfunction masking making discerning social issues hard - Reactive attachment disorder - Anxiety disorders - Depressive disorders - Bipolar disorder - Disruptive mood dysregulation disorder - Substance use disorders - Personality disorders – emotional dysreg, emotional intrusiveness - Psychotic disorders - Medication-induced symptoms of ADHD – think thyroid - Neurocognitive disorders >> not characterized by fear of abandonment or ambivalence which are characteristic of these personality disorders. AGE RELATED CRITERIA - Ramtekkar (2013), suggested using age related criteria for diagnosing ADHD, he reported that older girls were underdiagnosed. - The new DSM V uses specific criteria for diagnosing adolescents 17 and older. In addition, the age of symptoms can now be present up to age 12 (DSM V) as compared to age 7(DSM IV). DIAGNOSTIC CRITERIA DSM IV (2000) DSM V (2013) DIAGNOSTIC CRITERIA DSM IV (2000) DSM V (2013) DIAGNOSTIC CRITERIA DSM IV (2000) DSM V (2013) AGE OF SYMPTOM ONSET BEFORE AGE 7 BEFORE AGE 12 MULTIPLE SETTINGS (1+) CLINICALLY SIGNIFICANT IMPAIRMENT SYMPTOMS INTERFERE EXAMPLES CLIMBS/RUNS FEELING RESTLESS (for older patient) 4 5 EXCLUDING DIAGNOSIS PDD Schizophrenia Psychotic disorders CLASSIFICATION Schizophrenia Psychotic disorders or other mental disorder Classify mild severe Placed in Neurodevelopment Chapter DSM IV “There must be clear evidence of clinically significant impairment in social, academic, or occupational functioning”. DSM V “There is clear evidence that the symptoms interfere with, or reduce the quality of, social, academic, or occupational functioning”. ● Comorbidities: COMMON COMORBID DISORDERS ODD: oppositional defiant disorder, will get worse if the patient is not properly medicated for ADHD. Kids with this often won’t wear seatbelts, get lots of tickets, may get their license suspended (signs to look out for when considering why the meds aren’t working) LD: learning disorder, if you’re treating them with the right ADHD meds and they aren’t getting better, need to consider this a possibility. Conduct Disorder: less common but more severe, behaviors lead to jail time Injuries- head injuries, incidental injury Peer Challenges – relationship problems? Look for anxiety, delinquency, mood disorder COMORBID DISORDERS IN THE MINORITY Anxiety/Depression MOOD Conduct Intermittent explosive disorder COMORBIDITY MAY OCCUR WITH ADHD - Adults: antisocial and other personality disorders - Obsessive-compulsive disorder - Tic disorders - Autism spectrum disorder 5 6 ● Treatments and side effects: ○ ○ ○ ○ ○ Stimulants are considered the most effective medication, but three nonstimulants (one selective norepinephrine- reuptake inhibit and two alpha2adrenergic agonists) are also efficacious. First line: stimulants, methylphenidate and amphetamine compounds. They work by increasing the availability of neurotransmitters at the neuron synapses by blocking the transporters that remove dopamine and norepinephrine in the pathways in key areas of the brain where ample bioavailability of these compounds is essential by decreased. ■ Stimulant side-effects: decreased appetite, weight loss, insomnia, stomach-ache, and headache. Typically, symptoms resolve after a while. Concerns about growth exist but studies do not confirm this. 20% of children may develop tics after starting medication—often mild and typically resolve within a year. First line for preschoolers is behavioral therapy or group parent training Atomoxetine (straterra) is a non controlled, non-stimulant medication approved as a first-line medication for ADHD for children older than age 6 years old. ■ Common side effects: decreased appetite, GI complaints (anorexia, nausea), somnolence/ dizziness, mild increase in BP or HR. Most sx resolve, headache usually persist but can be managed with dose reduction or change of med ■ Few reports: liver toxicity, SI/ SA; not to be used in pts with HTN or tachyarrhythmias Second line or adjunct medications: ■ ER guanfacine (Intuniv) and ER clonidine (Kapvay) used in children 6 years old and older. Intuniv helps improve oppositional symptoms especially impulsivity ■ Kapvay (CLONIDINE) especially helpful in children with sleep issues. ■ These meds are less likely to be abused, do not worsen tics, take 2 weeks to work ■ AE: these alpha agonists may cause sedation, bradycardia, abdominal pain You should review the Burn’s chapter and take note of the section on the statistics related to ADHD. Estimates in US - from 5% (APA) to 8% (AAP) to 11% (CDC). Males 13.2% and females 5.6% per CDC % of children diagnosed with ADHD ages 4 to 17 increased 42% b/w 2003 to 2011 in one study but in another, no evidence to suggest increase - just better awareness, access to treatment, and changes in clinical practice (possibly). 7 years old is the average age of diagnosis. Severe is diagnosed earlier than age 7. Prevalence varies by state: low in Nevada of 5.6% to high in Kentucky of 18.7% Boys have higher prevalence 2:1 in childhood; 1.6 to 1 across all ages and girls are more likely to have the inattentive features. 6 7 Racial and ethnic disparities - African American or Hispanic children are 69% less likely to be diagnosed. Becoming more aware internationally - very few people receive diagnosis due to lack of awareness and social stigma and lack of community frameworks Be sure you review the meds used to treat ADHD and know the side effects of the meds. What are the most common side effects of stimulant ADHD drugs? Side Effects, Contraindications, Cardiac Warning, and Tics. Decreased appetite, weight loss, insomnia, stomach-ache and headache. Contraindications: psychosis. Cardiac warning - no association b/w stimulants and atomoxetine (see below about atomoxetine) and CV effects - stroke, MI, or sudden death - however, do not give to those with “serious heart problems” ... Screen for 1) cardiac history - SOB with exercise, exercise intolerance, fainting or seizures with exercise, palpitations, elevated BP, previously detected cardiac abnormalities, rheumatic fever, cardiomyopathy, &/or dysrhythmia. 2) Family cardiac history sudden unexplained or cardiac death before age 35, any rate, rhythm, or structural cardiac problems in the family, and 3) complete physical examination with special attention to the cardiovascular system. A screening tool for sudden death risk factors among children starting stimulant medication is available online ( https://www.icsi.org/_asset/60nzr5/ADHD-Interactive0312.pdf ) Tics - about 20% develop tics Stimulants may worsen anxiety disorders Liver toxicity with Atomoxetine have been reported Few reports of suicidal thinking or attempts with atomoxetine Atomoxetine - possible increased BP or HR so FDA recommends not to use in hypertension or tachyarrythmias Second line med - guanfacine-> sedating, bradycardia, abd. pain From Burns…. Saltine crackers with the morning dose of stimulant medication can decrease complaints of stomach aches. Instant breakfast drinks and other high-calorie foods supplement calories when the child has low caloric intake because of difficulty sitting through meals or side effects of medications. Cyproheptadine (Periactin) is sometimes used as an appetite stimulant. For sleep: Melatonin (2 to 6 mg/day), low dose clonidine, or an antihistamine may be helpful; however, long-term use of these agents is not supported by clinical evidence. Medication selection depends on the age of the child, the desired timing and length of coverage, other coexisting conditions, and insurance coverage. Amphetamines and methylphenidates - first line med’s - need to assess substance abuse Adderall XR) (mixed amphetamine salts) for ages 6+ Amphetamine and dextroamphetamine (Adderall) (mixed amphetamine salts) - not extended release - for ages 3 and up, FDA approved for ages 3-5. 7 8 Dextroamphetamine (Dexedrine) for ages 3-5 Lisdexamfetamine (Vyvanse) ages 6-12 Methylphenidates Methylphenidate (Concerta) - non-crushable - ages 6+ Dexmethylphenidate (Focalin) ages 6 - 17 Methylphenidate (Ritalin) ages 6+ Non-stimulant and alpha agonists Strattera - Atomoxetine - may take 2-4 weeks to peak effect, give with food to minimize adverse effects. Guanfacine - Intuniv - may take 2 weeks, do not give with high fat meal, do not stop abruptly Clonidine - may take 1-2 weeks, do no stop abruptly Depression: BURNS chapt. 19 Specific etiology unknown. Some biology and genetics + environmental factors responsible. ● Screening: USPSTF recommends screening only when there are supports in place for you to assure a dx, treatment, and follow-up. If all these are met, screening adults is appropriate. > looks a lot like bipolar! Be sure to ask if they can stay up for days on end, impulsive or reckless behaviors? Interspersed in depressive episodes. > depression can also be mistaken for dementia: impaired or inconsistent mood, disorientation, neuro deficits (aphasia, apraxia). Ppl with this were previously able to function, Use the mini mental tool to rule this out. > notes: weight changes, sleep dist, fatigue, decreased interest in pleasurable things may be indicators that something is going on if this person doesn’t identify as depressed and/or anxiety. s/s - ruminating, memory impairment, difficulty making day to day decisions, poor concentration, sleep, psychomotor, appetite PE - flat affect, slow speech, anxiety, hyper, evidence of self neglect (unbathed, dirty clothes), decline in work and school performance Diagnosis: test only to rule out other conditions like CBC if you’re worried about fatigue or metabolic syndrome, TSH?. Diagnosis is made off the HPI and hx. 8 9 Hard to read chart, but stick to DSM V and make sure the symptoms are disruptive and they have at least 5 s/s. ● SIGECAPS ○ Sleep ○ Interest ○ Guilt ○ Energy ○ Concentration ○ Appetite ○ Psychomotor ○ Suicidal SIGECAPS FOR DEPRESSION Dysthymic = s/s 2 yrs, milder, need 2 or more s/s rather than 5. Treatment: ○ ● First line treatment of MDD is psychotherapy and/or antidepressant medication. ■ GOLD STANDARD is to combine psychotherapy and medication ○ Can be mutually decided by you and the patient depending on disease severity. ○ Medication preferred if: ■ Hx of good response to medication ■ Sx are severe ■ Significant disturbance of sleep and appetite ■ Severe agitation ■ Lack of available alternative tx ○ SSRIs= 1st line treatment ○ SNRIs= 2nd line treatment or 1st line treatment in patients who complain of fatigue, chronic pain disorders, chronic back pain, or migraines. ■ May cause HTN! BE AWARE! ○ TCAs and MOAIs= 2nd line treatment due to more side effects. Length of treatment? 6-9months then reassess ● Side Effects ○ ○ SSRI and SNRI Side Effects: Sexual dysfunction, GI disturbances such as nausea, slowed GI motility ■ Others: agitation, anxiety, sleep disturbance, tremors, headaches Serotonin Syndrome: ABD pain, diarrhea, flushing, sweating, hyperthermia, lethargy, mental status changes, tremor, rhabdomyolysis, renal failure, CV shock and potentially death. (Usually occurs when coadministered with MAOIs, triptans, lithium, amphetamines, and some analgesics such as tramadol or meperidine). ● esp. special populations such as youth or the elderly: higher rates and risk in elderly. ○ ○ Physical disorders that are chronic and painful are assoc with depression in elderly Stressful life events 9 10 ○ Normal grief responses need to be differentiated from Major Depressive Disorder(MDD). ● Associated disorders: anxiety, OCD, substance abuse, stroke, HTN, diabetes, Cancer ● Special Populations: ○ ● Pregnant women: TCAs and SSRIs can be used in pregnancy for moderate to severe depression ■ SSRIs are 1st line- Fluoxetine most safety data. ○ Breastfeeding women: 1st line is Sertraline, Paroxetine, and Nortriptyline (safe in breastfeeding mothers). ○ Pediatrics: Fluoxetine and Escitalopram are the only antidepressants approved for children 12 year old and older. ■ Paroxetine has shown to increase adolescent suicide! ■ Black box warning for SSRIs and suicide amongst adolescents, especially in the beginning, monitor closely! FOLLOW UP IN 1 WEEK. ■ Combination therapy of CBT and pharmacotherapy gold standard ○ Geriatrics: High risk group. Dementia can be mistaken for MDD. ■ Look for signs of dementia: insidious onset, long duration of symptoms, impaired or inconsistent mood orientation or behavior, cognitive impairment, neuro deficits, memory loss, no psych hx, confusion, disorientation. ■ TCAs can cause anticholinergic side effects in this population ■ When dosing, start low and go slow! Somatic symptoms Bipolar Disorder: Must be certain patient does not have bipolar because treatment is different! -> Cause them to be manic more often. ■ Cardinal feature is mania/hypomania mixed with MDD ■ Other Sx: Inflated self esteem, little need for sleep, racing thoughts, distractibility, irritability, reckless behavior, clear pattern of mood fluctuations, alternating depression and mania, family hx. Schizophrenia: BEWARE of red flag symptoms: Severe personality change, thought disorder, delusions, hallucinations, bizarre behavior. ● Onset usually in middle or late teens ● More common in males When to Refer or Consult: ● Suicide or homicide risk ● Severe mental confusion ● Delusions or hallucinations ● ETOH or drug abuse ● Bipolar disorder ● Depression not responding to typical measures 10 11 ● Depression with psych features SSRIs are generally considered to be safe drugs. They are the preferred class of antidepressants for treating children and adolescents, as well as elderly patients. They have a better side effect profile than other classes of antidepressants. ● GI disturbances, like altered GI motility and nausea & sexual dysfunction are the most common side effects. ● Agitation, anxiety, sleep disturbance, tremors, and headaches can also be side effects of SSRIs. Review the SSRIs and know which of the specific drugs should be avoided in certain populations of patients, as well as which specific SSRIs are considered to be safe in special populations (like peds (Fluoxetine & Escitalopram), geriatrics (Citalopram, Escitalopram, & Sertraline), pregnant (Fluoxetine), and breast feeding women(Sertraline and Paroxetine). SNRIs can be used as a second line treatment for depression or as a first line treatment for patients with significant fatigue or chronic pain syndromes like neuropathy chronic back pain, or migraines. The safety, tolerability, and side-effects include those found with SSRIs, but SNRIs can also cause hypertension so just be aware of this when prescribing them. Bupropion, mirtazapine, moclobemide, and venlafaxine *Bupropion is better for sexual side effects but it can make ppl more active. So be careful if the patient also has anxiety. Risk for suicide: ● Prior attempt ● Adolescent and young adults (impulsivity) ● Females more attempts than males ● Males more successful attempts ● Elderly white males (highest rate of suicide, especially with access to a gun) Review lecture from Athey St. John’s Wort (https://nccih.nih.gov/health/stjohnswort/sjw-and-depression.htm) In a 26-week clinical trial with 124 participants, St. John’s wort, a standard antidepressant (sertraline, an SSRI), and a placebo were similarly effective in treating major depression of moderate severity. NCCIH and NIMH funded this 2012 analysis of data collected in 2002. Combining St. John’s wort with certain antidepressants can lead to a potentially lifethreatening increase of serotonin, a brain chemical targeted by antidepressants. Symptoms occur within minutes to hours, and may include agitation, diarrhea, fast heartbeat, high blood pressure, hallucinations, increased body temperature, and more. ● Taking St. John’s wort can weaken many prescription medicines, such as: ○ Antidepressants ○ Birth control pills ○ Cyclosporine, used to prevent the body from rejecting transplanted organs ○ Digoxin, a heart medication 11 12 ● ○ Oxycodone, a pain medicine ○ Some HIV drugs, including indinavir ○ Some cancer medications, including irinotecan ○ Warfarin, an anticoagulant (blood thinner). Other side effects of St. John’s wort are usually minor and uncommon. They may include upset stomach, dry mouth, headache, fatigue, dizziness, confusion, sexual dysfunction, or sensitivity to sunlight. Also, St. John’s wort is a stimulant and may worsen feelings of anxiety in some people. Anxiety ● Screening: ● Treatment: ● Side Effects ● esp. special populations such as youth or the elderly Often patients present with other comorbidities (90% of the time) including: ● Mood ● Substance abuse psychosis GAD is often mistaken for other diagnoses and can easily be missed: ● Physical/psyc distress ● Somatic disturbance ● Sleep disturbance Four Common Anxiety Disorders: 1. Panic Disorder (PD): Reaches peak within minutes (10 minutes) and with palpitations, sweating, shaking, SOB, choking, CP, N/adb distress/dizzy Intense fear, unexpected —> progresses to —> full on panic attack 2. Social Anxiety Disorder (SAD): a person fears they will do something weird or wrong during a social situation. This causes them to compensate or act strangely in social situations, validating fear and eventually avoid these situations. Must last longer than 6 months, must cause clinical distress, and not attributed to other causes 3. Generalized Anxiety Disorder (GAD): Persistent, excessive, worry and tension Common worries 3/6, only one for children Restless, easily fatigued, impaired concentration, irritability, muscle tension, sleep disturbance 6 months, present for more days than not 4. No longer lists Obsessive Compulsive Disorder (OCD) and Posttraumatic Stress Disorder 12 13 (PTSD) ● Screening: PC-PTSD, PCL-PC, M-3 —> Have you experienced a trauma that still haunts you? 13 14 ● ● Treatment: Daily SSRI/SNRI, Use prazosin for nightmares, anxiolytics may be needed as a bridge for severe symptoms until antidepressants provide relief, Benzos are generally not recommended, prolonged exposure - cognitive processing therapy Side Effects: SSRIs - HAs, nervousness, insomnia, sedation, fatigue, nausea, diarrhea, dyspepsia, appetite loss Bipolar: ● ● ● Looks a lot like depression! Screening ○ Characterized by: presence of mania (bipolar I disorder) or hypomania and depression (bipolar II disorder) ○ Mania: euphoria, expansive/irritable, co-occurring with persistently increased goal-directed activity or energy, inflated self-esteem, confidence, decreased need for sleep, pressured speech, racing thoughts, distractibility, increased involvement in goal-directed activities ○ The MDQ is a tool that combines DSM-IV criteria and clinical experience to screen for bipolar disorder in primary care settings. It uses a brief, one-page selfreport questionnaire with 13 yes-or-no items and two additional questions regarding functioning and timing of mood symptoms and typically can be completed in 5 minutes or less. Treatment/ Side effects: ○ one mood-stabilizing drug and/or atypical antipsychotic, plus psychotherapy. The most widely used drugs for the treatment of bipolar disorder include lithium carbonate and valproic acid (also known as 14 15 Depakote or generically as divalproex) 15 16 ○ Suicide Risk Factors: ● ● ● Historical and biological risk factors (history of suicide attempts, family history of suicide, male gender, history of childhood trauma) Mood, anxiety, and psychotic symptoms; substance abuse; encourage patient to mobilize psychosocial resources-contact family members for support. Access to firearms Eating Disorders: ● Eating disorders cause abnormal eating behaviors that are secondary to altered body image (dysmorphism). Anorexia nervosa (commonly called anorexia) and bulimia nervosa (commonly called bulimia ) are the primary eating disorders of concern; however, there are other conditions in this diagnostic cluster, including eating disorder not otherwise specified, rumination disorders, pica, and feeding disorders of infancy. ● Diagnostic criteria for anorexia: ○ Refusal to maintain body weight at least 85% expected for age and height or failure to gain weight during growth periods so that weight drops below 85% expected 16 17 ○ Intense fear of weight gain and “being fat” ○ Body dysmorphism ○ Binge eating/ purging subtype, which is associated with frequent purging although bingeing episodes are rare ■ Diagnostic criteria for bulimia: ■ Consuming large quantities of food in a short period of time (within 2 hours) ■ Loss of control during binge episodes (e.g., can't control the amount of food they eat or are shocked at the amount consumed) ■ Engaging in repeated behaviors to lose weight, including purging, excessive exercise, or fasting ■ Binging or purging behaviors that occur at least once a week for at least 3 months ● Screening tool: SCOFF questionnaire: ○ Do you make yourself Sick because you feel uncomfortably full? ○ Do you worry that you have lost Control over what you eat? ○ Have you lost Over 10 pounds in the last 3 months? ○ Do you believe you are Fat when others say you are thin? ○ Would you say Food dominates your life? ● Treatment: CBT, antidepressants, atypical antipsychotics, fluids/ electrolytes (inpatient management GI/Adult General recommendations to narrow diagnoses • History is essential: ● ● ● ● ● Timeline Of Symptoms Associated Symptoms,especially bowel changes Relationship To Meals,specific foods,or dietary changes/travel Other Associated Risk Factors,particularly smoking and drinking history (social hisotry) Location of pain and has that changed? • This will help you to narrow your focus, based on anatomy that corresponds to the location of pain ● Consider special populations ○ Who will decline more rapidly? ○ How might children and elderly patients present differently ■ Infant with abd pain- what should be done when compared to an adult ○ When must you do additional work up or what red flags require more urgent evaluation? 17 18 Appendicitis Acute infection of the appendix caused by obstruction of the appendiceal lumen followed by bacterial overgrowth and invasion of the wall of the appendix Risk factors: Median age for children is 10-11 year age for adults is 28 year, most common in summer months, foreign body, obstructive neoplasms (10-30 y.o.). ● Symptoms: ○ Fever, R sided abdominal pain that might start closer to umbilicus (periumbilical), localizing to RLQ over time, +/- nausea and vomiting. Rebound and guarding. ○ Positive Peritoneal signs: guarding & rigidity ○ ○ Obturator sign - passive R hip flexion and tightening of internal obturator muscle causing abd discomfort, ○ ○ Mc Burney’s point - most pain with pressure found here in RLQ, ○ Psoas - lie on L side, passive extension of R hip while supine causes pain IN RLQ ● Diagnostic Labs: ○ CBC w/ Diff, CT Scan, Ultrasound in children and pregnant women, UA ○ Imaging only recommended when diagnosis is equivocal ● Differential diagnoses: ○ Mesenteric Adenitis, gastroenteritis, UTI, ureteral calculus, diverticulitis, IBS, Ectopic pregnancy, ovarian cyst, PID ● Treatment: ○ Removal of appendix 18 19 Pancreatitis: Rapid onset of LUQ and epigastric pain that radiates to the mid back (boring). Severe pain, particularly LUQ or epigastric often radiating to the back Associated with heavy alcohol use, episodic binge drinking ● Risk factors: ○ Associated with ■ heavy alcohol use ■ Hypertriglyceridemia ■ episodic binge drinking ■ Gallstones ■ biliary sludge ■ microlithiasis. ● Symptoms: ○ Severe pain, particularly LUQ or epigastric area, often radiating to the back. Acute onset of fever, nausea and vomiting. Abdominal exam reveals guarding and tenderness over the epigastric or upper abdomen. ● Presentation: ○ may see a Cullen’s sign - ecchymotic discoloration to periumbilical region, edema of the SQ tissue ⇒pancreatic necrosis. Grey Turner sign - blue/bruising discoloration to flanks → retroperitoneal hemorrhage. ○ ○ Hypoactive bowel sounds can signal ileus, jaundice, guarding, and board-like upper abdomen if peritonitis. ● Evaluation: ○ Diagnosis of acute pancreatitis is typically defined by at least two of the following criteria: ■ (1) abdominal pain consistent with the disease, ■ (2) serum amylase or lipase greater than three times the upper limit of normal, or ■ (3) characteristic findings from abdominal imaging 19 20 ● Diagnostic labs: ○ ○ ○ ○ AST, ALT, Amylase, CBC Elevated amylase, lipase, and trypsin Elevated AST, ALT, GGT, Bilirubin, Leukocytosis, and other values Abdominal US and CT- usually provides a visual of the inflamed pancreas.. ● Differential diagnoses: ○ PUD, Abdominal aorta aneurysm, hepatitis, cholecystitis ● ● Medical therapy of acute pancreatitis is primarily supportive, with the major objective being hemodynamic stabilization. Antibiotics should not be started routinely but should be given for extrapancreatic infection. In mild acute pancreatitis, oral feedings can be started immediately if there is no nausea and vomiting and abdominal pain has resolved. In mild pancreatitis, initiation of a low-fat solid diet appears as safe as a clear liquid diet ● Hydration (with LR or NS), analgesia, nutritional support, O2, antiemetic, Ca and Mg replacement therapy, Blood Glucose monitoring and control PUD: Most common cause of upper GI Bleed. Epigastric pain, improves/not worsening with meals. Can experience changes in their stool or bloody emesis. ● Risk factors: ○ H.Pylori, daily use of NSAID/Aspirin ● Symptoms: ○ Epigastric pain, improvement with meals or no change with meals 20 21 ○ Associated symptoms, such as stool changes or bloody emesis ■ Dark stools, melena, coffee-ground emesis ○ Dyspepsia ○ LUQ, RUQ, or back pain ○ GI bleeding ○ Or asymptomatic ○ Duodenal ulcers: pain occurs 2-5 hours after eating and at night → improves with eating Gastric ulcers: epigastric pain worse after eating. May experience postprandial belching and fullness, early satiety, intolerance to fatty foods, nausea, vomiting, bloating, gas, weight loss, and loss of appetite ○ OLDER PEOPLE AND THOSE ON NSAIDs are unlikely to show symptoms until bleeding!! ● How does this compare to GERD? It is similar, but PUD is more abdomen associated symptoms with GERD being more esophagus and upper respiratory tract discomfort. ● Evaluation: ○ Endoscopy (if showing signs of bleeding or suspicious for other conditions) and Barium Esophagography ○ CBC, lipase, CMP ● Diagnostic labs: ○ testing for H. Pylori ■ Stool antigen or mucosal biopsy ■ Can use urea breath test ○ Test of cure for H. Pylori ■ Urea breath test or stool antigen after tx complete ● Differential diagnoses: ○ esophageal ca, GERD, gastroparesis, IBS, Celiac, pancreatitis ● Treatment: ○ Treat the cause, and stop the cause. PPI, H2 agonist, or sucralfate. ○ The best evidence-based recommendation for H. pylori eradication is for 14day triple therapy: PPI + clarithromycin + either amoxicillin or metronidazole ○ Quadruple therapy: PPI + Bismuth + Metronidazole + Tetracycline ○ Sequential Therapy: PPI + Amoxicillin x5 days, then Clarithromycin +Tinidazole x4 days. ○ Test of cure? How often do you perform a test of cure? ■ Once is adequate, 4-6 wk after tx complete and off PPI x 1-2 weeks to avoid false negative 21 22 Cholecystitis and Cholelithiasis: ● Risk factors: ○ Women, cystic fibrosis with pancreatic insufficiency, diabetes mellitus, or family history of biliary colic; pregnancy; rapid weight loss; Native American Pima Indian or Scandinavian descent; patients taking estrogens, progestins, or ceftriaxone; and those requiring total parenteral nutrition. ○ A mnemonic for remembering risk factors for cholesterol gallstones is the 5 F's: ■ Fat (overweight) ■ Forty (age near or above 40) ■ Female ■ Fertile (premenopausal- increased estrogen is thought to increase cholesterol levels in bile and decrease gallbladder contractions), and ■ Fair (gallstones more common in Caucasians). ● Symptoms: ○ RUQ pain, may be worse after meals- 1 hour after fatty meals on occasion. ○ Accompanied by N/V ○ Positive Murphy’s sign: indicative of gallbladder inflammation. ask pt to exhale, place hand below costal margin on R at mid clav line, ask to inhale and palpate area near gallbladder fossa near liver edge: positive when pt winces or catches their breath as you do the test. ● Differences between ○ Cholecystitis: Inflammation of the gallbladder ○ Cholelithiasis: presence of gallstones in the gallbladder 22 23 ○ Differences in treatment? ● Evaluation: ○ Abdominal ultrasound and ruling out other causes of abdominal pain, When calculi, gallbladder wall thickening, and gallbladder sludge are found, the diagnosis of acute cholecystitis is almost certain. HIDA scans can give false negative with ETOH/opiate abuse and other liver disease.

With poor circulation, blockages can form and compromise the function of these organs. ● ● ● ● ● Risk factors: atherosclerosis, blood clot Symptoms: abdominal pain, bloating, dark stool, n/v Evaluation: abdominal XR, CT Scan Diagnostic labs: CBC, CMP, Coagulation panel, ABG, ECG Differential diagnoses: UC, Infectious colitis, large bowel obstruction, peptic ulcer disease, Pancreatitis ● Treatment: Resuscitation, antibiotics, ex lap/laparotomy Cirrhosis vs. NAFLD (Non-Alcoholic Fatty Liver Disease): ● Cirrhosis and esophageal varices ○ Stool changes? Frank or occult blood? ○ Hepatomegaly ○ Skin changes and physical findings? ○ History of heavy drinking over time ● Risk factors: ○ Cirrhosis: ETOH, hepatitis B or C ○ NAFLD: Obesity, PCOS, Metabolic syndrome, diabetes, dyslipidemia ● Symptoms: ○ Cirrhosis: Jaundice, enlarged or tender liver. Stool changes, occult blood. Skin changes and a history of drinking over time- liver disease ○ S/S of liver dysfunction: Temporal and proximal muscle wasting, Stigmata-spider nevi, palmar erythema, gynecomastia, and caput medusae, Ascites, Hepatic encephalopathy. Increase jugular venous pressure-seen with right sided heart failure-suggest hepatic congestion. Right pleural effusion- May have enlarged liver and spleen.

Diverticulitis is the most common complication of Diverticulosis. ● Diverticula are small pouch-like herniations on the external surface of the colon secondary to a chronic lack of dietary fiber; higher incidence in Western societies ● Diverticulitis occurs when diverticula; high risk of rupture and bleeding; can be life-threatening ● Hospitalize if: Patient is elderly, has a high fever, leukocytosis, comorbidities, or is immunocompromised ● Acute diverticulitis: If acute abdomen, positive for rebound, positive Rovsing's (sign of acute appendicitis) sign, and board-like abdomen, refer to ED ● Diverticulosis: Physical exam is normal; no palpable mass; no tenderness ● Risk factors: old age, obesity, smoking, diet low in fiber and high in animal fat, lack of exercise, medications such as NSAIDs, steroids, or opioids. ● Symptoms: ○ Associated with constipation ○ Lower abdominal pain and tenderness, often in LLQ ○ Fever ○ Not associated with alcohol ○ Possibly associated with dietary changes -> ask about dietary changes ● Evaluation: Diagnosis can be made solely on assessment and history once ruling out other causes of abdominal pain ● Diagnostic labs: CBC, urinalysis, and flat and upright abdominal radiographs (shows free air). CT with contrast for suspected acute colonic diverticulitis 25 26 ● Differential diagnoses: IBS, IBD, colon cancer, ischemic colitis, bowel obstruction, and gynecologic and urologic disorders ● Treatment: Conservative medical management of uncomplicated diverticulitis includes bowel rest and IV fluoroquinolones or extended-spectrum penicillins. Cipro and Metronidazole is the antimicrobial treatment along with rest and hydration. ● ** If the patient does not improve after several days, an abscess should be suspected and diagnostic imaging considered. Hepatitis: Treatment for each, pharmacologic options for each, prognosis for each? Acute inflammation of the hepatic parenchyma. ● Risk factors: IV drug use, bacterial and fungal sources, autoimmune and metabolic disorders, toxic poisoning, and various hepatotoxic medications (e.g., isoniazid, acetaminophen) ● Hepatitis may result from various causes, both infectious (ie, viral, bacterial, fungal, and parasitic organisms) and noninfectious (eg, alcohol, drugs, autoimmune diseases, and metabolic diseases). ● Symptoms: low-grade fever, fatigue, lethargy, anorexia, RUQ pain, nausea, vomiting, diarrhea, arthralgias and myalgias, and (in severe cases) dark urine and jaundice ● Evaluation: Tenderness over the liver occurs with percussion and deep palpation. ● Diagnostic labs: AST/ALT, Hepatitis Panel, Bilirubin, transaminases, ALP, GGT ● Differential diagnoses: EBV, HSV, Cytomegalovirus ● Treatment: Therapy with pegylated interferon and ribavirin has been shown to achieve sustained viral eradication in almost 50% of patients with hepatitis C. Antiviral treatments for Hepatitis B are indicated for patients with moderate to severe disease diagnosed on liver biopsy; which includes interferon, lamivudine, and adefovir. Remove the cause, avoid hepatotoxic agents such as alcohol, tylenol, and statins (Pravachol). Treatment is supportive. Drugs that may cause elevated liver enzymes: Acetaminophen Augmentin and other ATBs Herbal supplements Valproic acid and other anti-epileptics Ketoconazole Vitamin A Methotrexate Dantrolene Glyburide Amiodarone Thiazolidinediones 26 27 Sulfonamides Chemotherapy drugs Synthetic retinoids NSAIDs Statins Anti-tuberculosis drugs Azathioprine > intrahepatic cholestasis can be caused by: anabolic steroids, BCP, penicillins, cimetidine, estradiol > Cholestasis: is defined as a decrease in bile flow due to impaired secretion by hepatocytes or to obstruction of bile flow through intra-or extrahepatic bile ducts. Therefore, the clinical definition of cholestasis is any condition in which substances normally excreted into bile are retained. What are the pharmacologic options for management? Acute Hepatitis A Treatment for acute hepatitis caused by hepatitis A virus (HAV) is necessarily supportive in nature, because no antiviral therapy is available. Hospitalization is warranted for patients whose nausea and vomiting places them at risk for dehydration. Patients with acute liver failure require close monitoring to ensure they do not develop fulminant hepatic failure (FHF), which is defined as acute liver failure that is complicated by hepatic encephalopathy. HAV IgM: acute infection. HAV IgG: resolved HAV Acute Hepatitis B As is the case for acute hepatitis A virus (HAV) infection, no well-established antiviral therapy is available for acute hepatitis B virus (HBV) infection. Supportive treatment recommendations are the same for acute hepatitis B as for acute hepatitis A. Lamivudine, adefovir, dipivoxil, and other antiviral therapies appear to have a positive impact on the natural history of severe cases of acute HBV infection. A study by Schmilovitz-Weiss described a rapid 27 28 clinical and biochemical response in 13 of 15 patients with severe acute hepatitis B who received lamivudine. HBsAG: chronic infection ● Typically, PEG-IFN treatment is continued for 48 weeks for both HBeAg-positive and HBeAg-negative chronic hepatitis. Oral agents may be used for as short as 1-2 years; however, most HBeAg-positive chronic hepatitis patients and almost all HBeAg-negative chronic hepatitis patients require indefinite therapy with these agents. Withdrawal of oral nucleoside/nucleotide analogue therapy in these individuals usually results in virologic relapse. Acute Hepatitis C Acute hepatitis C virus (HCV) infection is detected infrequently. When it is identified, early interferon (IFN) therapy should be considered. In one study, 44 patients with acute hepatitis C were treated with IFN alfa-2b at 5 million U/day subcutaneously (SC) for 4 weeks and then three times per week for another 20 weeks. About 98% of patients developed a sustained virologic response (SVR), defined as an undetectable level of serum HCV RNA 6 months after completion of antiviral treatment. Most experts now equate achievement of an SVR with viral eradication or cure of HCV infection. Treatment of Hepatitis D and E Treatment of patients coinfected with hepatitis B virus (HBV) and hepatitis delta virus (HDV) has not been well studied. The only effective treatment for HBV/HDV coinfection is pegylated interferon (PEG-IFN); antiviral nucleos(t)ide analogues have limited or no effect on HDV replication. However, multiple small studies have demonstrated that patients with HBV-HDV coinfection are less responsive to IFN therapy than patients with HBV infection alone.Treatment with PEG-IFN alfa-2b produced HDV RNA negativity in only 17-19% of patients. Lamivudine appears to be ineffective against HBV-HDV coinfection. Treatment of patients infected with hepatitis E virus (HEV) infection is supportive in nature. https://emedicine.medscape.com/article/775507-treatment GERD: DIFFERENTIATE FROM PUD Poor esophageal motility resulting in reduced clearance of the gastric contents in the esophagus •A dysfunction of the lower esophageal sphincter. The LES acts as a valve that helps to reduce the amount of gastric contents that refluxes into the esophagus. Relaxation can be related to things like alcohol, drugs (benzos), and caffeine. •Delayed gastric emptying that results in increased pressure forcing gastric contents to reflux. Overeating, eating too fast, diabetic gastroparesis. •Hiatal hernia and obesity contribute to symptoms ● Risk factors: 28 29 Conditions that can increase your risk of GERD include: Obesity, Bulging of the top of the stomach up into the diaphragm (hiatal hernia), Pregnancy, Connective tissue disorders, such as scleroderma, Delayed stomach emptying Factors that can aggravate acid reflux include: Smoking, Eating large meals or eating late at night, Eating certain foods (triggers) such as fatty or fried foods, Drinking certain beverages, such as alcohol or coffee, Taking certain medications, such as aspirin ● Symptoms: heartburn, regurgitation, dysphagia. Associated with meals, exacerbating foods and behaviours. Changes in behavior make it better. ● Evaluation: ○ EGD and manometry can help to confirm the diagnosis and evaluate for complications like esophagitis, strictures, Barrett esophagus, and motility disorders. ○ 24-hr pH probe test can help if the diagnosis is not clear, atypical symptoms ● Diagnostic labs: None- most often provider does a medication/lifestyle modification trial and if symptoms improve the diagnosis is made ● Differential diagnoses: CAD, nonulcer dyspepsia, PUD, esophagitis ● Treatment: ○ LifestyleModifications ■ Weight Loss ■ Avoid alcohol, chocolate, citrus, tomato-based products, peppermint, coffee, and any other products that contribute to symptoms ■ Avoid overeating ■ Wait several hours before lying down after meals ■ Elevate the head of the bed ○ PPI (“-zole”): Omeprazole (Prilosec), Esomeprazole (Nexium), Lansoprazole (Prevacid), Pantoprazole (Protonix) ■ ■ ■ MOA: Proton pump inhibitor (PlPI); binds to H+/K+-exchanging ATPase (proton pump) in gastric parietal cells, blocking acid secretion, metabolized in the liver Differences: PPI increase the pH of the stomach Standard-dose PPI treatment should be prescribed for 4 weeks in patients with duodenal ulcers and for 8 weeks in patients with gastric ulcers ■ Efficacy: most effective for tx ulcers ● Long-term use associated with hip fx, PNE, C-diff infection, hypocalcemia, hypomangnesemia. Do not d/c PPIs abruptly because doing so can cause rebound symptoms. Taper the dose!!!. 29 30 ○ H2 Blockers (“-idine”) : Ranitidine (Zantac), Nizatidine (Axid), Famotidine (Pepcid) ■ MOA: H2-receptor antagonist; blocks H2 receptors of gastric parietal cells, leading to inhibition of gastric secretions, Metabolized in liver ■ Differences: Works best on empty stomach without food. Almost all H2 blockers don’t work well after 2-6 weeks. The stomach adjusts and they become much less effective. ■ Efficacy: ○ Antacids: Calcium Carbonate (Tums, Caltrate), Aluminum-Mg-Simethicone (Mylanta, Maalox), Aluminum Mg (Gaviscon) ■ MOA: Neutralizes gastric acidity, be mindful of renal clearance Differences: ■ Efficacy: Antacids don’t do anything to prevent GERD, but they can be used on demand for symptom relief. Only last a short period of time ○ In patients with mild, intermittent therapy: Step up therapy■ Incrementally increasing the potency of therapy until symptoms are controlled. Adjust treatment every 2-4 weeks. Lifestyle and dietary modifications and H2 receptor antagonist (i.e. Ranitidine), along with antacids prn (i.e. Tums) If continued symptoms, increase the dose of the H2RA to twice daily for a minimum of 2 weeks. If still persists, stop the H2RA and initiate a PPI at a low dose, then increase to standard dose if needed.Once controlled, continue treatment for 8 weeks. ● In patient with erosive esophagitis, frequent or severe symptoms, consider step down therapy. ○ Start with potent anti-secretory, and then incrementally decrease the potency of therapy until breakthrough treatment is controlled. Standard PPI x 8 weeks, then low dose PPI, then H2RA. Only continue long term therapy in patients with severe erosive esophagitis or Barrett’s esophagus. ○ Any patient with at least a decade or more hx of chronic heartburn should be referred to a gastroenterologist for endoscopy to rule out Barrett’s esophagus. Irritable Bowel Syndrome (IBS) ● Functional GI disorder that presents with abdominal pain, bloating, altered bowel habits in the absence of specific pathology ● Sx: constipation, diarrhea, postprandial urgency, alternating diarrhea and constipation; may ℅ dyspepsia, n/v, GERD ○ Pain may be diffuse or specifically in lower abdomen / LLQ ○ Dull ache with episodic sharp pains ○ Pain may be precipitated by meals, may be relieved by BM ○ Splenic flexure gas may cause LUQ pain or anterior chest pain ● Stools may have mucoid appearance 30 31 ● ROME IV criteria for diagnosis of IBS ○ Abdominal pain averages at least 1 day / week during previous 3 months associated with at least two of the following: ■ Pain with defecation ■ Associated with change in stool frequency ■ Associated with change in stool appearance or form ● Diagnosis for patients under 50 without alarm features based on history and physical ● Alarm features: weight loss, iron deficiency, family hx of IBD, celiac disease, colorectal cancer ● Management ○ Fiber supplements ○ Increase water intake ○ Limit caffeine ○ Avoid gas producing foods like legumes ○ Possibly probiotics ○ If stress related, psychological interventions / therapy may help ● Pharmacologic therapy ○ Anticholinergics like dicyclomine (Bentyl) ○ Antidiarrheals (Lomotil, Imodium) ○ Bulk forming laxatives ○ Antispasmodics (peppermint oil, bentyl) Inflammatory Bowel Disease (IBD) → (Ulcerative Colitis and Crohns): Chronic functional d/o of the colon marked by exacerbations and remissions. Commonly it is exacerbated by stress. ● Ulcerative colitis involves the mucosal layer of the sigmoid colon and rectum in the vast majority of cases, causing proctitis and proctosigmoiditis. Mucosa is inflamed ● Crohn disease differs from UC in that it may involve any part of the GI tract from the mouth to the anus, including the gallbladder and biliary tree, and involves the entire thickness of the bowel wall. It is most often found in the immunologically rich terminal ileum, and Crohns disease involves the rectum in less than 50% of cases. In contrast to UC, the mucosal abnormalities are discontinuous (“skip lesions”), asymmetric, and patchy, which account for obstruction, abscesses, and perianal fistulas to other organs and skin. In Crohns likely to have small bowel strictures, upstream dilation of intestine and increased fistula formation, and eventual bowel obstruction and the imminent need for surgical intervention. Intestinal obstruction with scarring and strictures First line therapy for Crohn’s Disease or UC is Oral aminosalicylates ● Risk factors: Genetic factors, ● Symptoms: ○ UC: mild to moderate diarrhea and intermittent with flare ups, patients can go into remission without therapy, bloody stool 31 32 ○ Crohns: Vague abdominal pain, mild diarrhea, bloody as there is colonic involvement, bone loss, growth failure in peds, ○ Mucous in the stool is not specific and is found in IBS and IBD ● Evaluation: ○ UC: Confluent erythematous rectal inflammation, pseudopolyp formations indicate chronic inflammatory colitis ○ Crohns: solitary aphthous ulcers (canker sores), “rakelike” lesions, strictures, and rectal sparing, Anal or perianal lesions, including sinus tracts, rectovaginal fistulas, and abscesses, is consistent with Crohn disease. Mucosa may appear cobblestoned or nodular ○ Colonoscopic evaluation should include ileal intubation and biopsies of both normal and abnormal mucosa. ○ Colonoscopy and biopsy (Gastroenterologist): • Abnormal mucosa with or without ulceration extending from the rectum to all or part of the colon. • Uniform inflammation without intervening areas of normal mucosa • Contact bleeding and mucus in the bowel lumen Ulcerative Colitis grading: ● Mild - bleeding per rectum, <4 BMs/day, mild LLQ tenderness, PE might be normal ● Moderate - bleeding per rectum, >4 BMs/day ● Severe - bleeding per rectum, >4 Bms /day, fever or other systemic symptoms, abd pain, weight loss. ● Diagnostic labs: CBC, CMP, LFTs, inflammatory markers (sed rate, CRP), stool studies, serologic tests (ANCA, ASCA), xray (shows free air or obstruction), CT, MRI, EGD, Colonoscopy ● Differential diagnoses of UC: Lower GI bleeding, acute diarrhea, Crohn’s dz. ● Differential diagnoses of Crohns: Abd pain, acute diarrhea, chronic diarrhea, UC, small intestinal tumor. ● Treatment: Steroids are effective for inducing but not maintaining remission in IBD. ▪ The 5-aminosalicylic acid (5-ASA) medications, sulfasalazine, are effective in ulcerative colitis (UC) for therapy induction and maintenance therapy but largely are ineffective for Crohns disease ● Budesonide, a non systemic steroid used in an enema formulation, has been effective for induction of remission in Crohn disease and distal UC flares. ● Azathioprine and its metabolite, 6-mercaptopurine, are slow-acting compounds proved effective for inducing remission in Crohn disease. ● Methotrexate is also effective for remission induction in Crohn disease. Close monitoring of CBC and serum transaminases is recommended, with monthly testing on initiation and with dosage changes. Pregnancy and exposure to live-virus vaccines should be avoided. 32 33 ● Infliximab (remicade), an anti–tumor necrosis factor α antibody, is remarkably effective in treating approximately 60% of steroid-resistant patients with Crohn disease. Infliximab has significant side effect risks, including infusion reactions, and, rarely, worsening of heart failure, activation of latent tuberculosis, serum sickness, and invasive fungal infections ● Can supplement dietary fiber using psyllium (Metamucil/Konsyl) methylcellulose (Citrucel) wheat dextrin (Benefiber). Start low and increase because it can cause gas. ● Avoid gas-producing foods-> beans, onions, cabbage, high-fructose corn syrup. ● For abd pain can give antispasmodics Dicyclomine (Bentyl) or Hyoscyamine PRN ● Most pts with Chron’s will need surgery at some point in their lives. ● Increase fiber intake!! For IBS Alarm features: ** Alarm features would include weight loss, iron deficiency, family history of IBD, celiac disease, colorectal cancer GI Bleed, Melena: ● Risk factors: ETOH, Blood thinners, clotting factor disorder, liver failure, PUD ● Evaluation: EGD or Colonoscopy depending on where the blood is suspected to be ● Diagnostic labs: CBC, comprehensive panel, coagulation profile, iron studies (including transferrin saturation), reticulocyte count (before transfusion), and blood type and crossmatch Aortic Aneurysms: ● Risk factors: -MAIN RISK FACTORS: Male sex, >65 years old, smoking history 33 34 -OTHER RISK FACTORS: family hx of AAA, CAD, HTN, PAD, previous MI, cerebrovascular disease, atherosclerosis, other vascular aneurysms, hypercholesterolemia, obesity. ● ● ● ● ● ● ● ● Screen: The USPSTF recommends one-time screening for abdominal aortic aneurysm (AAA) with ultrasonography in men ages 65 to 75 years who have ever smoked. Symptoms: “tearing” epigastric pain and a pulsing sensation, no relation to activity or meals, no n/v/d, pain may radiate to back Evaluation: Abdominal US, Non-contrast CT although CT angiography (CTA) is the best diagnostic and pre intervention planning study, accurately delineating the location, size, and extent of the aneurysm and the involvement of branch vessels. Diagnostic labs: U/S is initial imaging of choice. CTA best for pre intervention Differential diagnoses: PUD, SBO, Diverticulitis Treatment: Treatment of lipids and HTN, antiplatelet therapy, referral to vascular surgery, surgery needed if >5.5cm or grows more than ½ cm in 6 months Who is most at risk? Males, over the age of 65 who have a history of smoking What populations should be screened in primary care? Men aged 65-75 y.o. Who have ever smoked. How might children or elderly patients present differently? When must you do additional work up or what are red flag signs in these populations that require more urgent evaluation? ● Infants & young children at risk because: ○ Greater % body water _GREATER FLD DEMANDS ○ More rapid metabolic rate and H2O turnover ● Elders at risk because: ○ Reduced kidney function ○ Less resilient body systems ○ Decreased fluid intake _GREATER FLD DEFICITS ○ More likely to take meds that affect fluids and electrolytes GI/Peds Urgent Evaluation: ● ● ● ● ● ● Risk factors: Symptoms: Evaluation: Diagnostic labs: Differential diagnoses: Treatment: 34 35 Hydration/Dehydration: ● ● ● ● ● ● Risk factors: Diarrhea, vomiting, inadequate fluid intake, excessive urine loss, draining wounds, gastric suction, ostomies, burns, and excessive sweating Symptoms: ○ Mild - can they still cry? Will be able to make tears, 3-5% weight loss, normal VSS, maybe slight decrease in UO, USG >1.020 (concentrated). Normal skin turgor. ○ Moderate: decrease tears, poor skin turgor, 5-10% weight loss, thirsty, dry mucous membranes, no urine for >8 hours, appears or ℅ thirst. Might see depressed anterior fontanelle. ○ Severe: weight loss 10-15%, tachycardic, orthostatic hypotension, dry MM, thirsty, no tears, anterior fontanelle is down, oliguria, skin is tented, cool, and mottled. Evaluation: for recent travel, relationship to food, presence of blood, ill contacts, meds, I&Os, associated pain? Diagnostic labs: Electrolytes, Pregnancy test, drug levels for toxicity, CBC, ESR, UA, BUN/Cr, Stool analysis Differential diagnoses: Gastroenteritis, amebiasis, lactose or food intolerances, Meds (Abx), IBS, Colitis, Diverticulitis Treatment: Mild and moderate can be replaced orally with electrolyte fluids. Gatorade is ok but not preferred d/t CHOs which can be hard to tolerate. If Breastfeeding- continue BF. use small amounts of frequent ingestion so you don’t induce vomiting. If severe → IV therapy. Increase diet slowly starting with bland solids. Appendicitis: ● ● ● ● ● ● Risk factors: M>F Symptoms: fever, anorexia, nausea, vomiting, tenesmus (feeling the urge to defecate, distressing and painful), migratory RLQ abdominal pain, abdominal tenderness and guarding, and signs of peritoneal irritation Evaluation: Classically, hours after onset, the pain migrates to the McBurney point , defined as the point two thirds the distance from the umbilicus along a straight line toward the anterior superior iliac spine of the pelvis. The Rovsing sign (referred tenderness from LLQ → RLQ during palpation), psoas sign (pain elicited by extending hip posteriorly with patient lying prone), and obturator sign (pain elicited by abducting right hip with patient lying supine, flexion of the hip) are often conducted but are of little diagnostic value. Diagnostic labs: Differential diagnoses: Treatment: Gastroenteritis: Viral is most common, bacterial can be from food poisoning, c diff, salmonella... and don't forget about Giardia (protozoa) ● Risk factors:eating contaminated food sources (giardia in wild game), salmonella ● Symptoms: n/v/d 35 36 ● ● ● ● ● ● Evaluation: Diagnostic labs: none needed unless you suspect severe dehydration. Differential diagnoses: Treatment: restore hydration, absorbent meds, reduce inflammation with pepto, anti spasmodics, antiemetics. Stick with light diet, may use advil for fever and pain. Need to closely monitor and watch > Medications: If you do the above and the patient is not getting better in 48 hours or has blood present in the stool… > stool testing, o&p, cbc, cmp. C Diff- Metronidazole first line, Vanc works too E. Coli, Shigella, Campylobacter- If >18, Cipro 36 37 PUD: Duodenal ulcers are more common than gastric ulcers, but gastric are more likely to be malignant. Helicobacter pylori is a common cause of both. ● Risk factors: chronic NSAID use that disrupts the prostaglandin production reducing GI blood flow and reduces the protective mucus layer. Tobacco and/or alcohol use, stress after acute illness, ventilator support, extensive burns, or a head injury. ● Symptoms: ○ Worrisome symptoms: early satiety, anorexia, anemia, recurrent vomiting, hematemesis, wt. Loss. ○ Episodic epigastric pain, burning/gnawing pain, or ache. Pain is relieved by eating/antacids with recurrence 2-4 hours after a meal. Pain recurs when the stomach is empty or they are hungry. ○ Stools can be black/tarry, red/maroon, coffee-ground emesis, or iron-deficiency anemia indication GI bleeding. ● Evaluation: Abd exam normal/mildly tender epigastric area during flare-ups. Hemoccult can be + if actively bleeding. ● Diagnostic labs: ○ CBC: iron-deficiency anemia-> bleeding, fecal occult blood test ○ All patients with PUD should be tested for H. Pylori infection ■ Positive-> refer to gastroenterologist. ■ Serology Titers: H. Pylori immunoglobulin IgG levels elevated. Don’t use to evaluate eradication of H. Pylori after treatment. ■ Urea breath test: indicative of active H. Pylori infection and is commonly used to document eradication of Hy. Pylori after treatment. ■ Stool Antigen: Can be used for screening and posttreatment to document eradication. ● Stool antigen and Urea blood test are more sensitive for active infection than serology/titers. Gold Standard: Upper endoscopy and biopsy of gastric and/or duodenal tissue are gold standard tests. ● Differential diagnoses: ● Treatment: PPI to inhibit gastric acid secretion and promote ulcer healing ○ Stop the use of NSAIDs, can decrease the risk with use of PPI or Misoprostol. ○ Smoking cessation ○ Lifestyle changes + PPI or H2 Blocker. Duration of therapy is 4-8 weeks. If there is no response, poor response, or recurrent ulcers after 4-8 weeks of therapy suspect a bleeding ulcer and refer to GI. ○ PPI: ■ Omeprazole (Prilosec) 20mg Daily ■ Esomeprazole (Nexium) 40mg Daily ■ Lansoprazole (Prevacid) 15-30mg Daily ○ H2 Blockers: ■ Ranitidine (Zantac) 150mg BID of 300mg at bedtime ■ Nizatidine (Axid) 150mg BID or 300mg at bedtime ■ Famotidine (Pepcid) 40mg at bedtime. 37 38 ○ Treatment of H. Pylori- Positive Ulcers: ■ Triple Therapy: ● Clarithromycin (Biaxin) 500mg BID + Amoxicillin 1gm BID or Metronidazole (Flagyl) 500mg BID (if allergic to Amoxicillin) for 14 days. ■ Quadruple Therapy: ● Bismuth subsalicylate tab 600mg QID plus ● Metronidazole tab 250mg QID plus ● Tetracycline capsule 500mg QID x2 weeks plus ● PPI for 4-8 weeks to allow the ulcer to heal. Intussusception: Intussusception involves a section of intestine being pulled antegrade into adjacent intestine with the proximal bowel trapped in the distal segment. The invagination of bowel begins proximal to the ileocecal valve and is usually ileocolic, but it can be ileoileal or colocolic. Intussusception is thought to be the most frequent reason for intestinal obstruction in children. Risk factors ● Intussusception most commonly occurs between 5 and 10 months of age and is also the most common cause of intestinal obstruction in children 3 months to 6 years old ○ 80% of the cases occur before 2 years of age ● In younger infants, intussusception is generally idiopathic and responds to nonoperative approaches. ● Known medical predisposing factors: ○ Polyps ○ Meckel diverticulum ○ Henoch-Schönlein purpura ○ Constipation ○ Lymphomas ○ Lipomas ○ Parasites ○ Rotavirus ○ Adenovirus ○ Foreign bodies. ● Intussusception may also be a complication of CF. ● Children older than 3 years are more likely to have a lead point caused by polyps, lymphoma, Meckel diverticulum, or Henoch-Schönlein purpura; therefore, a cause must be investigated. Symptoms ● The classic triad for intussusception, intermittent colicky (crampy) abdominal pain, vomiting, and bloody mucous stools, are present in fewer than 15% of cases ● Paroxysmal, episodic abdominal pain with vomiting every 5 to 30 minutes. o Vomiting is nonbilious initially 38 39 ● ● ● ● ● ● ● Some children do not have any pain. Screaming with drawing up of the legs with periods of calm, sleeping, or lethargy between episodes. Stool, possibly diarrhea in nature, with blood (“currant jelly”). A history of a URI is common. Lethargy is a common presenting symptom. Fever may or may not be present; can be a late sign of transmural gangrene and infarction. Severe prostration is possible Evaluation ● Observe the baby's appearance and behavior over a period of time; often the child appears glassy-eyed and groggy between episodes, almost as if sedated. ● A sausage-like mass may be felt in the RUQ of the abdomen with emptiness in the RLQ (Dance sign); observe the infant when quiet between spasms. ● The abdomen is often distended and tender to palpation. ● Grossly bloody or guaiac-positive stools. Diagnostic labs/Studies ● Abdominal ultrasound is very accurate in detecting intussusception and is the test of choice ● Abdominal Flat plate x-ray is only accurate ~60% of the time ● An air contrast enema is both diagnostic and a treatment modality Differential diagnoses ● Incarcerated hernia ● Testicular torsion ● Acute gastroenteritis ● Appendicitis ● Colic ● Intestinal obstruction Treatment ● Radiologic reduction using a therapeutic air contrast enema under fluoroscopy is the gold standard ● Emergency management and consultation with a pediatric radiologist and a pediatric surgeon is recommended ● Rehydration and stabilization of fluid status; gastric decompression ● IV antibiotics are often administered to cover potential intestinal perforation. ● A period of observation following radiologic reduction is recommended (12 to 18 hours) Cardiac - PEDS Fetal Circulation: -Oxygenation of the blood occurs in the placenta, not the lungs -Fetal pulmonary vascular resistance is high, and systemic vascular resistance in low (High pressure on the right side of the heart, low pressure on the left) 39 40 -The foramen ovale, the opening in the septum between the two atria, permits a portion of the blood to flow from the right atrium to the left atrium -A patent ductus arteriosus provides a connection between the pulmonary artery to the aorta and bypass the fetal lungs -Fetal circulation is best described as two parallel circuits, with the left ventricle supplying blood to the upper extremities and the right ventricle serving the lower extremities and the placenta. -At the time of transition to extrauterine life, these separate blood flow circuits become a serial circuit. (See Burns pg. 756 for full description of circulation) Congenital heart disease Understand fetal circulation and how blood bypasses the lungs ● Risk factors: Perinatal: -Maternal infections and exposures- CMV, rubella, other viral syndromes -Maternal use of tobacco, alcohol, street drugs, retinoic acid,lithium, valproates, ibuprofen, naproxen, ACE inhibitors, tricyclic antidepressants, sulfonamides, sulfasalazine, and hydantoins. -Maternal chronic disease- CHD, lupus, insulin-dependent DM, phenylketonuria -Maternal age- increased risk of chromosomal abnormalities after 40 years old -Maternal pregnancy hx-excessive weight gain, gestational DM Neonatal: -fetal or newborn distress- hypoxia, aspiration -prematurity -Presence of associated anomalies- genetic or chromosomal abnormalities and syndromes -Neonatal infections (GBS) -Birthweight- term infants <2500grams, SGA < two standard deviations from the mean for gestational age Newborn: -murmur at birth or early infancy -HTN at birth or beyond -Feeding difficulty -Cyanosis -Tachypnea Toddler, School aged, Teens: -deviation from individuals normal growth pattern -frequent respiratory tract infections -prior murmurs, blue spells -documented GABHS infection -HTN -SOB with exertion 40 41 -CP with exertion -syncope, dizziness -Tachycardia, bradycardia Family HX: -CHD (especially 1st degree relatives) -Sudden death or premature MI -SIDS -HTN -Rheumatic fever -Genetic syndromes -Hypercholesterolemia ● Etiology: Caused by an alteration in development of or failure of the embryonic heart to progress beyond an early developmental stage. Occurs in the 2nd to 8th week of gestation due to genetic, environmental, or multifactorial influences. -Most cases have NO identifiable cause -2-4% caused by teratogens (lithium, ACE inhibitors, tricyclic depressants, sulfonamides, sulfasalazine, tobacco, alcohol, cocaine, marijuana, antiepileptics, retinoic acid, ibuprofen, naproxen, maternal conditions, environmental influences (organic solvents, pesticides, air pollution) -Maternal illnesses (DM, connective tissue disorders, phenylketonuria, rubella, febrile illnesses- especially influenza -Genetic abnormalities ● s/s of: -Infants: Tachypnea, Tachycardia, Rales, Wheezing, Cardiomegaly, Hepatomegaly, Periorbital edema, Poor feedings, Tires easily from feedings, Poor weight gain, Diaphoresis.

But if uncomfortable, have another coworker listen, or if not one else is able to help, refer to cardiology -Symptomatic or other signs of cardiac disease ->Refer -Early systolic, late systolic, holosystolic -> Refer -Grade 3 or more ->Refer -Diastolic and continuous murmurs ->Refer * No need for chest xray (Unless concerned for CHF) (won’t help you diagnose structural abnormality of the heart) or ECG (unless you notice dysrhythmia) ● pathologic -A murmur in a child with a syndrome associated with CHD (ex. Trisomy 21) -Any diastolic murmur -Any systolic murmur associated with a thrill -Pansystolic murmurs- what is significance of pansystolic murmur? -Continuous murmurs that cannot be suppressed -Systolic clicks -Opening snaps -Fixed splitting of the second heart sound not associated with BBB -An accentuated S2 -S4 gallops -Not positional -Grade III/VI or higher 42 43 -Harsh quality Causes of Pathologic murmur: Ventricular septal defect, Atrial septal defect, Patent ductus arteriosus, Tetralogy of fallot, Pulmonary stenosis, Coarctation of the aorta (MUST check FEMORAL pulses. In newborns and infants they may present with CHF and in older children they are usually asymptomatic or they may complain of leg pain), Aortic stenosis, Tricuspid atresia, Total anomalous pulmonary venous connection, Transposition of the great arteries. Diagnostics: ● Chest X-ray- to visualize cardiac size, size of specific chambers and great vessels, cardiac contour, status of pulmonary blood flow, status of lungs and other surrounding tissue. ● ECG: monitors electrical activity of the heart from different locations in the different planes of the body and gives information about forces of ventricular contraction, hypertrophy, chamber dilation, and rhythm. ● Echocardiogram: Detects intracardiac structures and their motion, detects arrhythmias and hemodynamic changes ● CBC: Rules out severe anemia or polycythemia as a cause of the murmur ● Other Diagnostics include: MRI (shows heart structures, and information about chamber volumes and function), Hyperoxia test (supplementation with 100% O2 that results in pinking and increased O2 saturation when the disease is primarily pulmonary), exercise testing (determine cardiac output in response to exercise for endurance and capacity) and Cardiac Cath (shows vascular resistance, cardiac output, heart anatomy, response of the heart to exercise and medications) Coarctation of the aorta Narrowing of a small or long segment of the aorta -Caused by a disturbance in the development of the aorta or secondary tot of the ductus arteriosus. - Newborns and infants may present with CHF, while older children are usually asymptomatic or may have leg pain or weakness - Higher incidence in females with Turner Syndrome - Associated with bicuspid aortic valve Hx: -COA not always apparent until ductus closes and decreases blood flow to the lower body. - complaints of tachypnea, poor feeding, cool lower extremities. -older children may complain of headaches, leg pain with exercise Physical: -Systolic ejection murmur heard best over interscapular region, normal S1S2, decreased or delayed femoral pulse,have have increased left ventricular impulse 43 44 -upper extremity hypertension with lower extremity hypotension (>20mmHg difference) -bounding brachial, radial, carotid pulses -signs of CHF -delayed timing and absent or weak arterial and other distal arterial pulses Work up: -Chest Xray: normal to slightly enlarged heart and normal to increased pulmonary vascular markers, rib notching may be seen -ECG: depend on severity of lesion and age of child. In infants- hypertrophy may be seen. In older children-LVH develops secondary to HTN Echocardiogram: helpful in confirming dx and locating the constricted aortic segment. May also show associated cardiac abnormalities. MRI: Can define location, severity, and anatomy of the aortic arch Patent ductus arteriosus -A blood vessel in the developing fetus connecting the trunk of the pulmonary artery to the proximal descending aorta. It allows most of the blood from the right ventricle to bypass the fetus's fluid-filled non-functioning lungs. Normal functional closing occurs 12-72 hours after birth. -Permanent closure at 2-3 weeks. -Patent ductus arteriosus is the failure of ductus closure causing a connection between the aorta and pulmonary artery. Aortic blood is shunted into the pulmonary artery and recirculates through the lungs. Hx: -Infant or child may be asymptomatic if the PDA is small. -Increasing signs of CHF may appear in the first weeks of life in larger PDAs. -PDA usually evident by 3 months. Physical: -In immediate postnatal period- murmur is soft, systolic, and heard along the left sternal border, under the left clavicle, and in the back. 44 45 -After the first weeks of life- typical grade II to V/VI, harsh, rumbling, continuous “machinery murmur” is heard in the left infraclavicular fossa and pulmonic area with a thrill at the base. -Physical findings of CHF may be present with a large shunt. Work up: Chest Xray: small to moderate shunt- heart is not enlarged. Larger shunts- both left atrium and left ventricle can show enlargement. ECG: large shunts show LVH, QRS axis is normal or rightward Echocardiogram: shows patent ductus and usually enlargement of left atrium Work up and clearance for Sports physical ● Contraindications: ○ Recurrent episodes of upper extremity pain or weakness ○ Severe hypertension- >160/100. ○ Sickle cell disease - increased rate of rhabdo and increased risk of sudden cardiac death ○ Suspected CAD ○ Active myocarditis or pericarditis ○ Acute enlargement of liver or spleen ○ Eating disorder ○ Hx of recent concussion and sx of post concussion syndrome- have to by symptom free for 1 week in order to return to sports. ○ Hypertrophic cardiomyopathy ○ Long QT ○ Poorly controlled seizure disorder ● See table 13-6- conditions of absolute contraindications Evaluation: ● PMH positive for following requires follow up questions (helpful to have parent in room for PMH): ○ Syncope/near syncope - vasovagal not as worrisome as other etiologies ■ Need to r/o wolff-parkinson white syndrome, long QT syndrome, and hypertrophic cardiomyopathy - get EKG ○ Heart murmur ○ Elevated BP ○ Prior cardiac testing ○ Prior restriction from sports participation ○ Eating disorders - prevalent in weight sensitive sports (gymnastics, wrestling, dance) ○ Psych disorders - are they stable? ○ Drug abuse ○ Anemia - work pt up for sickle cell, fatigue, heavy menses in females-> check CBC ● Family history positive for following may require follow up: ○ Premature sudden death <50 years old ○ Disability from CV disease <50 years old ○ HCM, dilated cardiomyopathy, long QT, Marfan 45 46 ● ROS: ○ Asthma - asymptomatic @ rest and exertion = cleared ○ Derm - open wounds, infections, tinea, herpes = ok to play but educate re: preventing spread ■ Musculoskeletal - confirm no sequelae to hx of injury ■ Neuro - hx of seizure - may not want to clear for water sports (higher risk of death if seizure during activity) ● Concussion - should NEVER return to play until asymptomatic ○ Physical exam red flags: ■ Tachycardia ■ Elevated bp ● <160/100 = ok to play, but counsel and monitor pt ● >160/100 = not cleared ■ Arrhythmia - get EKG ■ Murmur - assess sitting, lying, standing, squatting, during valsalva, after activity ● Systolic murmur most worrisome >> if increases with valsalva and decreases with squatting = hypertrophic cardiomyopathy = most common cause of sudden cardiac death ● Benign murmurs will not change with squatting ■ Marfan syndrome - refer if 2 or more of below are noticed: ● Height > 5’10” (females) or 6’0” (males) ● Kyphoscoliosis-> side to side curve and a front to back curve ● Pectus excavatum-> breast bone is indented ● Arm span > height ● Moderate - severe myopia Cardiac - Adult s/s cardiac disease in adults Utilizing testing appropriate to diagnosis Appropriate referral for CAD, CHF, and arrhythmias Education of s/s of heart disease What populations tend to have less obvious symptoms?

Test to evaluate heart disease and info they provide- ECHO, EKG, TROP, STRESS TEST, HEART CATH ● EKG: ○ ● ● ● Show nonspecific ST segment and T-wave abnormalities in pt with severe CAD. ■ This can have false positives in cases with LVH, digoxin intake, electrolyte imbalances, or conduction anomalies like BBB or pre-excitation syndromes. Echocardiography: ○ Done in new or worsening HF or new MI to assess LV function and regional wall motion. Exercise Treadmill testing: ○ Based on the pt ability to exercise ○ Measures the presence of ischemic ST segment changes, reproducibility of CP, arrhythmias, changes in BP and HR and functional capacity. ○ Sensitivity: 68%, specificity: 77% ○ Early positive result in the first two stages of the test can indicate a worse prognosis, and is considered a high risk finding. ○ If the pt experiences CP and -1 mm ST segment depression during exercise the test can be 90% predictive of the presence of CAD. ○ A 2mm ST segment depression + CP is indicative of the presence of obstructive CAD. ○ The presence of anti-ischemic agents (Nitrates, BBs, and CCBs) can reduce sensitivity and should be withheld 2-3 days prior to the test for long acting drugs and 24 hrs for short-acting drugs- IF the intent is to dx the presence of obstructive dz. ○ ABSOLUTE CIs to treadmill stress tests: decompensated CHF, symptomatic AVS, ongoing resting CP, recent MI (w/in the past wk), severe HTN, and intractable arrhythmias. ○ Nuclear stress tests and Stress Echos are the alternatives in this case. Stress myocardial perfusion imaging: Nuclear stress test: ○ More accurate to dx obstructive CAD 47 48 ○ ○ ○ ● ● Sensitivity (88%) and specificity (72%) Best ordered in those with intermediate likelihood of obstructive CAD Adenosine and Dobutamine commonly used. ■ Adenosine dilates the coronary arteries and shunt blood away from abnormalities. ● Can cause bradycardia and high degree AV block. ■ CI: in those w/ hyperactive airway dz (asthma) ■ NO CAFFEINE 12-24 hrs prior ■ Excellent choice for those who cannot walk on the treadmill ■ Dopamine increases HR and contractility and therefore increases myocardial O2 demand. ■ Reserved for those who cannot walk or the treadmill and those with a CI to Adenosine. Stress Echo: ○ Similar to nuclear stress test, but sensitivity is slightly lower. ○ Performed by obtaining initial resting echo images of the heart ○ Assesses LVEF, wall motion characteristics and cavity size. ■ 25% of pt may be difficult to obtain images: severe COPD and morbid obesity. ○ Pt then exercise on the treadmill to a limited protocol to a target HR of 85% of maximum predicted for age. ○ Once HR is met, post-stress images are obtained at target HR. MI: Acute mismatch of myocardial O2 supply and demand. ○ Classic presentation of acute MI: substernal chest pain radiating to the left arm, neck and jaw and interscapular area. Associated with SOB, nausea and diaphoresis ○ CPR and defibrillation if needed. Administer aspirin, and provide O2 if sat <90%> only if hypoxemia. (increases SVR, coronary vasoconstriction and increased oxidative stress) Consider the use of nitrates and analgesics. ○ Obtain a 12-lead ECG and note ST elevation. Mobilize hospital resources to respond to STEMI. Complete a fibrinolytic checklist if it’s indicated. ○ Check for contraindications for fibrinolytic therapy if indicated, and obtain initial cardiac marker labs, coagulation studies, and electrolyte panel. ■ Absolute contraindications to fibrinolytic: ● Hx of intracranial hemorrhage, structural cerebrovascular lesion, intracranial neoplasm, ischemic stroke </= to 3 months except for acute ischemic stroke within 4.5 hours, suspected aortic dissection, active bleed/bleeding diathesis, significant closed head/facial trauma within 3 months, intracranial/intraspinal surgery within 2 months, and/or severe uncontrolled HTN not responding to therapy. ■ Relative Contraindications: ● Chronic, severe, poorly controlled HTN; syst BP >180 +/- DBP AAA>110; ischemic stroke >3 mo. or dementia, known intracranial pathology not covered in absolute contraindications, CPR >10 minutes or major surgery <3 weeks; internal bleeding within 2-3 weeks; noncompressible vascular punctures; pregnancy; active peptic ulcer; and/or warfarin therapy 48 49 ○ ○ ○ ○ If O2 sat <90%, start O2 at 4L/min.

What are abnormal variations? Abnormalities of S1: ● LOUD S1: Short PR interval, mild mitral stenosis, hyperdynamic states ● SOFT S1: Long PR interval, severe mitral stenosis, LBBB, COPD, Obesity, pericardial effusion ● VARIABLE S1: AV dissociation, A-fib, Large pericardial effusion and severe LV dysfunction (auscultatory alternans- alternates loud and soft) S2: -Easiest to hear at the upper sternal border -Normally split during inspiration (Contributions from aortic and pulmonic valves are not simultaneous) -Intrathoracic pressure decreases during inspiration and leads to increased right ventricular preload, then increased right ventricular systole, delaying P2 -Decreased LV preload during inspiration leads to shorter LV systole, earlier A2 53 54 Abnormalities of S2: ● WIDE SPLIT: S2 mildly split during expiration and more dramatically split during inspiration ○ Caused by anything that delays RV contraction and thus P2 which makes LV contraction in A2 premature, increasing RV afterload or decreasing LV afterload ○ RBBB, pre-excitation of LV (Wolff- Parkinson White Syndrome), pulmonary HTN, massive PE, severe mitral regurgitation, constrictive pericarditis. ● FIXED SPLIT: S2 split equally in inspiration and expiration ○ Common in atrial septal defect or severe RV failure ● REVERSED SPLIT: Split heard on expiration, not inspiration (inverse of wide split) ○ LBBB, pre-excitation of RV (RV pacing, Wolff-Parkinson White Syndrome), aortic valve disease, LV outflow tract obstruction ● ABSENT A2: Severe aortic valve disease- seen in elderly ● FUSED A2P2: Occurs throughout respiration cycle-> Absent split ○ VSD in Eisenmenger syndrome, single ventricle- seen in pediatrics[ ● LOUD P2: Suggestive of pulmonary HTN- heard at apex. S3: -low pitched, early diastolic sound -Easiest to hear at apex when patient in left lateral decubitus position -Although occasionally heard in young healthy people and pregnant women-> in those over 40 years old = usually pathologic and indicative of LV failure -”Ventricular Gallop” S4: -low pitched, late diastolic sound (pre-systolic) -Always pathologic, though to be caused by atrial contraction into a stiff and non-compliant ventricle -Has been described in patients with afib and aflutter but the mechanism for this has yet to be explained. -”Atrial Gallop” Summation Gallop= S3 +S4 are superimposed during tachycardia Gallops: Usually originate from the left side of the heart, but can occur from right side -Left sided (ex. CHF)- Softer with inspiration -Right sided (ex. Massive PE)- louder with inspiration Clicks: ● Aortic Ejection Click: early is systole, opening of aortic valve, high pitched, heard everywhere if audible at all, not affected by patient standing ○ Indicated pathology of aortic valve ● Mitral Valve Prolapse Click: Occurs during mid-systole, caused by prolapse of one of the mitral valve leaflets, high pitched, audible only at apex, occurs earlier in systole when standing 54 55 Split S1 ● Normal split of S1, very narrow and not appreciable ● Causes○ S1 is actually split: tricuspid valve closure delayed relative to the mitral valve closure for some reason (RBBB, pre-excitation, idioventricular rhythm from left ventricle ○ 1st component of S1 is actually S4 ○ 2nd component of S1 is actually aortic ejection click ● True split S1: ○ Both components high pitched, heard best at LLSB ● S4 mimicking Split S1: ○ First component low pitched, second component is high pitched, heart best at the apex ● Aortic Ejection Click: ○ Both components high pitched, heard equally everywhere Significance of split S2 murmur? Grading of Murmurs: ● ● ● ● ● ● Grade I. Barely audible and may require several cycles to detect Grade II. Soft, but easily audible Grade III.

B B -AAA screening should not be performed in women who have never smoked. ● ● ● B Cardiac Tests What tests are done to evaluate cardiac structure and function and what information do these tests provide you with? When would you order these diagnostic tests or labs? EKG: ○ Show nonspecific ST segment and T-wave abnormalities in pt with severe CAD. ■ This can have false positives in cases with LVH, digoxin intake, electrolyte imbalances, or conduction anomalies like BBB or preexcitation syndromes. Echocardiography: ○ Done in new or worsening HF or new MI to assess LV function and regional wall motion. Exercise Treadmill testing: ○ Based on the pt ability to exercise ○ Measures the presence of ischemic ST segment changes, reproducibility of CP, arrhythmias, changes in BP and HR and functional capacity. ○ Sensitivity: 68%, specificity: 77% ○ Early positive result in the first two stages of the test can indicate a worse prognosis, and is considered a high risk finding. ○ If the pt experiences CP and -1 mm ST segment depression during exercise the test can be 90% predictive of the presence of CAD. ○ A 2mm ST segment depression + CP is indicative of the presence of obstructive CAD. ○ The presence of anti-ischemic agents (Nitrates, BBs, and CCBs) can reduce sensitivity and should be withheld 2-3 days prior to the test for long acting drugs and 24 hrs for short-acting drugs- IF the intent is to dx the presence of obstructive dz. 61 62 ○ ● ● ABSOLUTE CIs to treadmill stress tests: decompensated CHF, symptomatic AVS, ongoing resting CP, recent MI (w/in the past wk), severe HTN, and intractable arrhythmias. ■ Nuclear stress tests and Stress Echos are the alternatives in this case. Stress myocardial perfusion imaging: Nuclear stress test: ○ More accurate to dx obstructive CAD ○ Sensitivity (88%) and specificity (72%) ○ Best ordered in those with intermediate likelihood of obstructive CAD ○ Adenosine and Dobutamine commonly used. ■ Adenosine dilates the coronary arteries and shunt blood away from abnormalities. ● Can cause bradycardia and hig.h degree AV block. ● CI: in those w/ hyperactive airway dz (asthma) ● NO CAFFEINE 12-24 hrs prior ● Excellent choice for those who cannot walk on the treadmill ■ Dopamine increases HR and contractility and therefore increases myocardial O2 demand. ● Reserved for those who cannot walk or the treadmill and those with a CI to Adenosine. Stress Echo: ○ Similar to nuclear stress test, but sensitivity is slightly lower. ○ Performed by obtaining initial resting echo images of the heart ■ Assesses LVEF, wall motion characteristics and cavity size. ● 25% of pt may be difficult to obtain images: severe COPD and morbid obesity. ○ Pt then exercise on the treadmill to a limited protocol to a target HR of 85% of maximum predicted for age. ○ Once HR is met, post-stress images are obtained at target HR. Sensory: Visual changes associated with aging: ● Glaucoma group of diseases that damage the optic nerve ○ People who are high risk should have an exam every 2 years ■ (AA >40, ■ all adults >60 especially Mexican Americans, ■ those with a family history of glaucoma) ○ No acceptable test to accurately detect ■ Risk assessment for Open Angle Glaucoma: ● Increased IOP, older age, family history, AA ● Acute onset of severe eye pain.

Starts with gradual changes in peripheral vision and then central vision. ● Cataracts: ○ ○ ○ a clouding of the lens; leading cause of vision loss in the US Symptoms: blurry, hazy, glare, halos around lights and blurred vision Tx: surgery when symptomatic ● Macular Degeneration: ○ Major risk factors include: age, race (Caucasians), smoking, hereditary ○ Macular retinal changes such as blurred central vision or a blind spot in the center of the visual field ○ early= asymptomatic ○ Late= central vision loss (gradual or sudden) ○ Tx: Laser treatment, photodynamic therapy ○ Requires yearly eye examinations ● Diabetic Retinopathy: ○ Risk factors: hyperglycemia, worse with HTN ○ Common signs: retinal edema, microaneurysms, hemorrhages, exudates ○ Symptoms: asymptomatic, gradual vision loss, or sudden vision loss, cotton wool spots (fluffy yellow-white patches on the retina). ○ Tx: Glycemic and HTN control, laser surgery: hyper ○ Yearly eye examinations Acute problems in vision changes in aging: ● Iritis: ○ blurred vision, moderately severe pain/intermittent stabbing, moderate photophobia, no discharge, circumcorneal conjunctival injection, clear appearance of the cornea, constricted pupil size, normal or low IOP 63 64 ● Conjunctivitis: ○ normal vision, no pain, no photophobia, usually significant discharge with crusting of lashes, diffuse conjunctival injection, clear appearance of the cornea, normal pupil size, normal IOP ● Foreign Body/Corneal Abrasion: ○ ● ● pain, gritty feeling in the eye, tearing, redness, sensitivity to light, H/A, visualizing the cornea under cobalt-blue filtered light after the application of fluorescein will confirm the diagnosis ○ Always ask patient if they wear contacts. ○ Acute onset of severe eye pain with tearing.. Foreign body sensation on the surface of the eye. Acute symptoms to be concerned about and require a referral – decreased vision, eye pain, drainage or redness of the eye, double vision, floaters, circles/halos around light sources, flashing lights With all of the above, check for the following symptoms or signs ○ Reduced vision, pain, photophobia, corneal staining, corneal edema, unequal pupils, elevated IOP ■ Refer to ophthalmologist if any of these are present ● If none are present the above is probably conjunctivitis ○ Triad of red eye, pain and loss of vision should always alert the examiner to a potentially blinding condition Visual changes for pediatrics (amblyopia) ● Occurs when the eye experiences a blurred and normal view, but the brain only processes the normal view. ● Causes: ○ Deprivational (ptosis, cataract, nystagmus) ○ Strabismic (strabismus or lazy eye) ○ Refractive (myopia, hyperopia, astigmatism, anisometropia) <-most common visual disorder in children ● Patching of the dominant eye can allow for the weaker eye to become stronger ● Refer to ophthalmology ● Untreated or insufficient treatment in young childhood results in irreversible and lifelong vision loss Visual changes for adults (presbyopia) ● Presbyopia is caused by a loss of elasticity of the lenses which makes it difficult to focus on near or close objects. Onset in the early to mid-40’s. Can be remedied with reading glasses or bifocal lenses. ■ 64 65 Conductive hearing loss: ● Failure of normal transmission of acoustic energy of sounds through the middle ear (conductive part of the canal) BC>AC ○ ○ ○ Not as common- 10% Associated with cholesteatoma, cerumen impaction, foreign body in ear canal, ossicular problems, OM with effusion, otosclerosis, retracted TM (Eustachian tube dysfunction), tumor of ear canal/middle ear, TM perforation, tympanosclerosis Txt: Abx, or sx.

Often this is done in the hospital after birth. If they fail, they should have a follow up/repeat no later than 3 months of age. Children should have a hearing test before they enter school or anytime there is a concern for hearing loss. If they don’t pass, they need a full work-up/audiology referral Peds Ortho Know difference between legg-calve-perthes and slipped capital femoral epiphysis Slipped capital femoral epiphysis: ● Posterior displacement of capital femoral epiphysis from femoral neck through the cartilage growth plate ● More common in males and occurs bilaterally 25% of the time ● Most commonly occurs at puberty in obese children with delayed sexual maturation 66 67 ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● Physical Exam Findings Classic presentation: painful limp with/without a history of recent trauma Typically overweight and adolescent age years If a patient reports knee pain, always examine the hip, because knee pain may be referred pain from the hip via the obturator nerve. Patients often hold their affected hip in passive external rotation. Determine the patient's ability to bear weight (stable vs unstable). If the patient is ambulatory, determine his or her gait pattern: ○ Antalgic – Shortened weight bearing phase on the affected side and longer swing on the affected side Out-toeing Always examine both hips. ○ Assess the active and passive range of motion in both hips. ○ In patients with unilateral complaints, this comparison allows the clinician to compare the affected and unaffected sides for differences. ○ Internal and external rotation are best tested with the patient in the prone position with the knees flexed to 90 o. If SCFE is present, the lower extremity may externally rotate and abduct with gentle passive hip flexion. Internal rotation is decreased in nearly all hips with SCFE → painful! ○ Internal rotation is often painful Slight shortening of the involved lower extremity is observed in some patients May walk with a limp that involves swinging the affected foot outward SCFE is a Salter-Harris fracture type 1 Needs xray Treatment involves pinning or screws placed in surgery 67 68 Legg-Calves-Perthes ● Avascular necrosis of the capital femoral epiphysis ● Physical Exam Findings ○ Unilateral involvement is the rule ■ If bilateral case is suspected some form of epiphyseal dysplasia must first be ruled out ● Xray will look different than SCFE, growth plate will appear crushed History There can be an acute or chronic onset with or without a history of trauma to the hip, such as jumping from a high place. ● The most common presenting sign is an intermittent limp (abductor lurch-trendelenburg gait caused by weakness in the gluteal muscle), especially after exertion, with mild or intermittent pain. ● The most frequent complaint is persistent pain in the groin, anterior hip region, or laterally around the greater trochanter. ● Pain may be referred to the medial aspect of the ipsilateral knee or to the anterior thigh. ● Some children may report limited range of motion of the affected extremity. Physical Examination. ● ● ● ● ● ● ● ● ● ● ● Antalgic gait with limited hip movement Trendelenburg gait resulting from pain in the gluteus medius muscle Muscle spasm Atrophy of gluteus, quadriceps, and hamstring muscles Decreased abduction- harder to move outward, limited and painful internal rotation, and extension of the hip Adduction flexion contracture Pain on rolling the leg internally Leg length inequality due to collapse of the femoral head Short stature: This result from deformity of the femoral head. Roll test: ○ With patient lying in the supine position, the examiner rolls the hip of the affected extremity into external and internal rotation. This test should invoke guarding or spasm, especially with internal rotation. Trendelenburg sign: ○ While standing, the patient lifts one leg up at a time; owing to muscle weakness on the affected side, the pelvis drops to the opposite side 68 69 Diagnostics ● Routine AP pelvis and frog-leg lateral views are used to confirm the diagnosis, stage the disease, and follow disease progression and response to treatment. ● Ultrasound can be helpful early in the disease ○ Useful in the preliminary diagnosis; capsular distention can be seen on sonographic images.

Refer for possible serial casing and bracing Club foot Idiopathic deformity of the foot of unknown etiology Most common in Polonesian heritage Talipes equinovarus (clubfoot) has three elements: 1. The ankle is in equinus (the foot is in a pointed-toe position) 2. The sole of the foot is inverted as a result of hindfoot varus or inversion deformity of the heel 3. The forefoot has the convex shape of MA (forefoot adduction). **The foot cannot be manually corrected to a neutral position with the heel down** Management ● X-rays ● Referral to ortho for serial casting using the Ponseti technique Genu Varum (Physiologic Bowleg) Normal variation of the lower leg in 1-3-4 year old age group Evaluation ● Ankles together and make sure feet are pointing forward ● Measure the distance between the knees ○ 5-6 inches or greater is considered pathologic ○ Abnormalities: 72 73 ■ Neurofibromatosis (unilateral tibial bowing) ■ Rickets gradually progresses , has short stature, atypical diet, and family history ■ Tibial torsion ■ Juvenile RA ■ Osteomyelitis ■ Neoplasm ■ Trauma ■ Blount’s disease (unilateral, common in obese, early walkers, Aftrican American, and Scandanavian children) Physical Exam ● Diffuse bowing of lower joints ● Internal tibial torsion ● Increased distance between both knees that is accentuated with standing ● Varus positioning of the heel with pronation of the feet may be noted on weightbearing ● Waddling gait and kick the heels on running to clear feet from ground to avoid hitting the contralateral limb Treatment ● Rarely indicated because the condition should resolve with growth ○ Serial measurements ● x-Ray: ○ bowing beyond 2 standard deviations for age height less than 25%, increasing severity, asymmetry of the limbs ● Pathologic genu varum associated with Rickets, dwarfism can be diagnosed with x-rays ● Unilateral bowing warrants immediate evaluation for an underlying disorder ● Persists beyond 7-8 years ortho referral definitely indicated Genu Valgum (Physiologic Knock-Knee) Normal variation in lower extremity configuration in children between 3 and 5 (7-8) years of age Physical Findings ● Increased distance between the feet with the medial aspects of the knees touching each other ● Ankles may appear to roll in and may correct when the knees are corrected Assessment ● Measure intermalleolar distance (should be less than 8cm) serially to monitor for progression ● Unilateral warrants immediate referral ○ Growth plate injury ○ trauma/infection/vascular insult ○ Neoplasm ○ Proximal metaphyseal tibial fracture ○ Benign tumor 73 74 ○ Ollier's disease Management ● Reassurance ● Serial measurement ● Referral for lack of spontaneous resolution by 7-8 Common Fractures: Salter Harris ● Bowing ● Buckle ● Greenstick Osgood Schlatter’s Disease: ● ● ● Often seen in adolescents after going through a rapid growth spurt the previous year.

This is the area that provides longitudinal growth to bones and eventually matures into bone. During growth, the physeal cartilaginous plate is weaker than the surrounding bone and often weaker than the ligaments and tendons that attach nearby, causing it to fracture before other areas. The SalterHarris classification system describes these injuries Growing Pains: ● ● ● ● ● ● ● ● occur in the evening or late in the day - may awaken child from sleep gone by the morning with no limitation of activity poorly localized and bilateral Occur commonly in the front of the thighs, shins, in the calves, and behind the knees transient and occur over a period of time as long as several years not associated with a limp or disability no fevers or swelling no recent or remote trauma Fractures 1. The skeletal system of children is anatomically, biomechanically, and physiologically different from that in adults. The presence of growth plates (or physes) in the pediatric skeleton is one major difference. The growth plate is composed of cartilage. It can be thought of as the "weakest link" in the pediatric bone. It may separate before an adjacent joint ligament tears. Injuries to the growth plate may result in deformities =Salter Harris Fractures 2. Another difference seen in children is a thicker periosteum surrounding the bones. As a consequence, fractures in children tend to be more stable and less displaced than those seen in adults. The greater bone-forming potential of the pediatric periosteum results in faster bone healing in children. Non-unions are rare in pediatric fractures. 3. A third difference is the increased porosity, due to larger, more abundant Haversian canals, and decreased density of pediatric bones. This feature makes children's bones more prone to buckling when compressed, or bowing when bent. 4. Finally, remodeling is more rapid in children than in adults. Imperfect reductions have been known to remodel into satisfactory alignment. The differences between pediatric and adult fractures result in different fracture patterns, problems of diagnosis, and management techniques. 76 77 5. ● ● ● ● Know significance of types of fractures Salter Haris- growth plate fractures Bowing - due to increased porosity Buckle - due to increased porosity Greenstick Types of growth plate fractures – 5 categories based on the type of damage caused. ● ● ● ● ● Type I – Fracture through the growth plate ○ The epiphysis is separated from the metaphysis with the growth plate remaining attached to the epiphysis. ○ The epiphysis is the rounded end of the long bones below the growth plate and the metaphysis is the wider part at the end of the long bones above the growth plate. ○ Type II – Fracture through the growth plate and metaphysis ○ Most common type of growth plate fracture. The growth plate and metaphysis are fractured without involving the epiphysis. Type III – Fracture through the growth plate and epiphysis ○ The fracture runs through the epiphysis and separates the epiphysis and growth plate from the metaphysis. ○ It usually occurs in the tibia, one of the long bones of the lower leg. Type IV – Fracture through growth plate, metaphysis, and epiphysis: ○ Fracture goes through the epiphysis and growth plate, and into the metaphysis. ○ This type often occurs in the upper arm near the elbow joint. Type V – Compression fracture through growth plate: 77 78 ● ○ ● Rare condition where the end of the bone gets crushed and the growth plate is compressed. It can occur at the knee or ankle joint. Signs and symptoms of a growth plate injury include: ○ Inability to move or put pressure on the injured extremity ○ Severe pain or discomfort that prevents the use of an arm or leg ○ Inability to continue playing after a sudden injury because of pain ○ Persistent pain from a previous injury ○ Malformation of the legs or arms as the joint area near the end of the fractured bone may swell ○ GU: hernia - worsens with high static demand (ie: weight lifting) 78
