PEDIATRICS REVIEW Jennifer K. Bell MHS, PA-C TOPICS The newborn assessment Newborn Problems Development Immunizations Specific Pediatric problems by system Genetic Disorders THE NEWBORN ASSESSMENT Apgar score Exam •SKIN: Erythema toxicum, mongolian spots •HEENT: fontanelles •CARDIAC: PDA •ABD/GU: hypospadias, hydrocele •MS: hip dislocation •NEURO: babinski is normal APGARS Done at 1 min and 5 min (may be repeated at 5 minute intervals for infants with 5 min scores <7) Score 0 1 2 Heart Rate Absent <100 >100 Respiratory effort Absent, irregular Slow, crying Good Muscle tone Limp Some flexion of extremities Active motion Reflex Irritability No response Grimace Cough or sneeze Color Blue, pale Acrocyanosis Completely pink Erythema Toxicum neonatorum (the rash of the newborn) COMMON skin condition in newborns, BENIGN Appears in 50% of newborns Usually between day 3 or life and 2 weeks of life Rash: small, yellow to white papules surrounded by red skin, usually on face, chest, back, upper arms, sometimes on thighs. Palms and soles are not involved No treatment needed. Usually fade and disappear over 2 weeks or more Erythema Toxicum neonatorum Acrocyanosis Mongolian Spots Benign Infantile Hemangioma Common 3 stages: Growth, Stabilization, Disappearance Most common complication is ULCERATION Usually no treatment required and a simple BIH resolves on its own. Further evaluation needed for : Very large or segmented hemangiomas (>5cm) Multiple hemangiomas Located over sacral spine or at the midline Located near the eye Ulceration Physical Exam of head, face, and neck Asses head for its shape, symmetry, and fontanelles. Caput succedaneum: It is subcutaneous and does cross suture lines Cephalhematoma: It is subperiosteal and does not cross suture lines Cephalohematomas, go away over the course of a few weeks. Caput succadaneum, goes away in a few days CARDIAC Patent Ductus Arteriosus (PDA) Failure of the ductus arteriosus to close in the first few days of life OR reopening after functional closure. Up to 60% in preterm infants weighing < 1500 grams Female to male ratio= 2:1 Systolic murmur that may be continuous, and is heard best at the upper left sternal border. MANAGEMENT: Indomethacin: a prostaglandin synthetase inhibitor, 80% CLOSURE RATE SURGICAL closure. The Abdomen Palpate the kidneys. Anus is visualized, but digital examination is not recommended unless obstruction is suspected. Meconium is usually passed in the first 12-24 hours. An absence of the passage of meconium by 24 hours may suggest either cystic fibrosis or Hirschsprung’s Disease. imperforate anus Genitals : Inspect the external genitalia for ambiguity Inspect the glans for the location of the external urethral meatus. In Hypospadias, the meatus is located in an abnormal ventral position. The presence of Hypospadias in the newborn indicates a contra-indication for circumcision. Genitals Testes should be descended into the Scrotum or in the inguinal canals. You can ultrasound the area to “find them” if you cannot feel them. Hydroceles or hernias are not uncommon in newborns. After a breech delivery, the external genitalia are often erythematous and edematous. Musculoskeletal The purpose of this examination is to detect gross abnormalities. The appearance of the extremities at birth usually reflects the positioning of the child within the uterus. Examine the hips for the possibility of dislocation. The presence of asymmetric skin folds on the medial aspect of the thigh, a positive galeazzi sign, and positive ortolani and barlow maneuvers are suggestive of a dislocated femur. There are risk factors associated with hip dysplasia, but one to remember is breech position. (ALL breech babies get an ultrasound of their hips done to rule out dysplasia) Positive galeazzi sign Ortolani Barlow Babinski sign is normal in newborns (> 2 years of age is abnormal) NEWBORN ISSUES Hypoglycemia Jaundice Hearing Hypoglycemia<40mg/dL Differential Insufficient glucose delivery Decreased glycogen stores Increased circulating insulin (infant of a diabetic mother, maternal drugs) Endocrine and Metabolic disorders Sepsis Hypothermia Polycythemia Asphyxia Shock Hyperbilirubinemia Total Serum Bilirubin Bilirubin peaks at age 5-6 days, then normally stabilizes and drops. Low risk zone: do nothing Low intermediate risk: possibly supplement if breastfeeding, recheck in 24 hours. Encourage to put in sunlight. High intermediate risk zone: consider bili-blanket (photo therapy) or a bililight. Ensure not dehydrated. May need IV fluids. Physiologic jaundice: normal Breastfeeding jaundice: lack of breastmilk Breastmilk jaundice: persists in breastfed babies for 3 weeks to 4 months. Normal. Remember Kernicterus Bilirubin >20-25 Can lead to permanent brain damage, even death. Hearing Routine hearing screening prior to discharge, using Auditory brainstem responses (ABR) Otoacoustic emissions (OAE) *If a child fails, further audiologic testing needed.

Immunizations Hep B Rotavirus Influenza Pneumococcal HIB Polio Dtap Hep A Varicella MMR HPV Meningococcus The schedule and also details about the conditions FIRST A HINT If you memorize a typical schedule of immunizations at well child visits, you will probably have a hard time missing a vaccine question regarding timing of vaccinations.

Fades in 4 days Erythema in a fishnet-like pattern begins on the extremities 2 days after the facial erythema. Extends to the trunk and buttocks fading in 6-14 days Stage 3: recurrent phase The eruption fades and then reappears in previously affected sites on the face and body during the next 2-3 weeks.

Roseola 80% of all children by age 1, 90% by age 2 Most cases are asymptomatic OR occur with a fever of unknown origin and NO rash Most cases between 6 months and 4 years Typically: very high fever, fever subsides and the rash appears. Febrile seizures common Kawasaki Disease: AKA Mucocutaneous lymph node syndrome Children: 7 weeks-12 years of age. (rare in adults) An acute multisystem vasculitis of unknown etiology (likely infectious cause) Cardiovascular manifestations are the main cause of morbidity Genetic Disorders Down Syndrome Klinefelter Syndrome Turners Syndrome Marfan Syndrome Down Syndrome-Trisomy 21 Mental retardation Single palmar crease Hypothyroidism Flat occiput, epicanthal folds, large tongue Congenital heart disease Turner Syndrome (XO) 1/2500 affected Physical characteristics Short stature Broad chest with widely placed nipples Low hairline Low set ears Webbed neck Amenorrhea Sterility Congenital heart disease, DM, vision problems, hypothyroidism, autoimmune diseases Turner Syndrome Kleinfelter Syndrome (XXY) Most common sex chromosome disorder 1/500 Long legs small, firm testes and gynecomastia Osteoporosis Motor delay or dysfunction Language and speech problems Attention deficits Behavioral and psychosocial problems Dyslexia or reading dysfunction Decreased fertility (thought to be the cause of 2-3% of male infertility) Kleinfelter Syndrome Marfan Syndrome Autosomal dominant, chromosome 15 Systemic connective tissue disease Tall stature, long arms and fingers Commonly scoliosis and pectus excavatum Displaced ocular lens Mitral valve prolapse Aortic root dilation-aortic regurgitation Aortic dissection and rupture The Last time you will likely ever endure a lecture with me GOOD LUCK TO YOU ALL!!!
