Nezgoda, MD, MBA Ophthalmology Resident University Hospitals Case Medical Center Cleveland, Ohio vii This page intentionally left blank PREFACE The Computer-based Case Simulation (CCS) portion of USMLE Step 3 comprises 12 interactive cases over 4 hours designed to evaluate your approach to patient management. This book was created to provide a high-yield, rapid, comprehensive review for the CCS cases. Studying for the CCS portion of Step 3 presents some unique challenges from studying for the multiple-choice question (MCQ) portion. Most important, understanding the USMLE CCS Primum® software is essential to performing well. As soon as you decide to take Step 3, download the Primum® CCS software from the official www.usmle.org website under “Practice Materials.” An in-depth review of the software is provided in this book. Practice the six cases that are supplied by the USMLE and get a good feel for how to place orders, what orders are available, how to manage the clock, how to transfer patients, and all the various features of the software. Practice the sample cases multiple times and see how the software responds to performing correct actions and performing incorrect actions. Once you are comfortable with the software, you can really start using this book and studying for the exam. This book incorporates the concept of bidirectional learning, which emphasizes relationship building and associative memories. Each CCS case is presented on two pages. The first page shows a brief sample case presentation with relevant information presented in a format similar to the actual exam. The second page presents a review of the disease entity with a focus on diagnosis, management, and important points in the CCS matrix. Each case can be studied beginning from the first page or the second page. How to Use This Book: As a self-test n To use as a self-test, begin with the first page of a case and read through the case presentation. In most cases, the diagnosis should be suspected from the information provided. On a blank sheet of paper or in your head, create a sequence for how you would manage the patient. Compare your management with what is presented on the second page. n As a review book n To use as a review book, start backward with the second page of a case. At the top, the final diagnosis is listed. Beginning with the final diagnosis, try to recall important points in the diagnosis and management. In addition, create a CCS matrix with the six domains and compare your results with those listed in the table provided. n As a practice exam n To use as a practice exam, open a CCS case in the USMLE Primum® software (Case 1 begins in the emergency department and Case 2 begins in the office). Begin with the first page of a case and read through the introduction. Using the software, order the appropriate management (exam, labs, imaging, and treatment). Compare what you did in the software with the management recommended on the second page. Preparing well for the CCS portion of Step 3 can have a dramatic impact on your overall Step 3 score. If you learn the concepts, strategies, and cases in this book, you should not just do well on the CCS cases, you should CRUSH them! I wish you much success on your exam, residency, career, and future. n Mayur K.

The best way to learn the software is to download the Primum® software from the USMLE.org website and practice the sample cases on it. Six CCS cases are provided by the USMLE for practice along with basic explanations. The following sections highlight important features of the software. Each year, the Primum® software undergoes minor updates and modifications so it is important to download the most recent version. The following section is updated to the 2012–2013 Primum® software. Scoring The USMLE does not publish exactly how each case is scored and how much of the overall Step 3 score the CCS portion accounts for; however, based on the time allocated to the CCS, it can be estimated that about 25% to 30% of your overall Step 3 score is based on your performance on the CCS cases. Any action you perform may add to, subtract from, or have no effect on your score. Of the thousands of orders and actions possible in the software, most will likely have no effect on your score. For each CCS case, there are multiple correct approaches that exist that will achieve a high score. Although we have tried in this book to outline management of cases consistent with widely accepted standards, there may be alternative approaches that are equally valid. Feel free to modify, adjust, and alter any recommendations in this book to your own preferences and experience. Real Time and Simulated Time The CCS portion consists of 12 cases: a combination of 10- and 20-minute cases in real time. At the beginning of each case, the Start Case screen will show you the allocated real time for each case. n 10-minute case: 8 minutes of case time + 2 minutes for case-end orders n 20-minute case: 18 minutes of case time + 2 minutes for case-end orders The following are examples of 10- and 20-minute real-time cases from the six practice cases on USMLE.org: n 10-minute Cases: n Case 1: Tension Pneumothorax n Case 6: Eclampsia with Fetal Distress n 20-minute Cases n Case 2: Rheumatoid Arthritis n Case 3: Ascending Aortic Dissection n Case 4: Asthma n Case 5: Diabetic Ketoacidosis with E. coli Sepsis In general, the 10-minute cases will be those that require rapid management with less follow-up required after definitive therapy. 1—PRIMUM® CCS SOFTWARE 3 Each case may last a few minutes to several months in simulated time. For patients who present with chronic conditions, such as rheumatoid arthritis, follow-up over several weeks of simulated time may be required. For each case, the real and simulated times are displayed at the bottom left of the screen. The Six CCS Domains Each case is scored according to six domains: diagnosis, therapy, monitoring, timing, sequence, and location. Every case in this book is analyzed according to those domains. For most cases, the orders are split into “optimal” and “additional” orders. The optimal orders are those that are most critical for management and likely to generate the highest points. The additional orders are those that either may generate a smaller number of points or may have no effect on your score but are often ordered. Some domains may not be important for each case. Each of the six domains is explained below with examples from the six CCS practice cases from the USMLE.org website. 1.Diagnosis: This can include physical examination, laboratory studies, imaging studies, or procedures. In some cases, a limited physical exam is all you need to reach a diagnosis. a.A patient who presents with tension pneumothorax in the emergency department (ED) should be diagnosed based on history and a limited physical exam. b.A patient who presents to the office with rheumatoid arthritis is diagnosed based on history, physical exam, lab studies, synovial fluid studies, and imaging. c.A patient who presents to the ED with ascending aortic dissection is diagnosed based on history and exam with confirmation by imaging (chest CT or TEE) d.A patient who presents to the ED with diabetic ketoacidosis is diagnosed based on history, exam, glucose measurement, ABG, and urinalysis. 2.Therapy: This can include medications, surgery, invasive procedures, consultation, counseling, or just simple reassurance. In some cases, canceling a medication that the patient was previously on may be part of the therapy. a.A patient with tension pneumothorax is managed with needle thoracostomy followed by chest tube or surgical consult. b.A patient with rheumatoid arthritis is managed with an NSAID or a corticosteroid, a DMARD (such as methotrexate), and either exercise counseling or physical therapy consult. c.A patient with eclampsia is managed with IV magnesium sulfate, IV antihypertensive medication, and fetal delivery either by C-section or consulting ob-gyn. d.A patient with diabetic ketoacidosis and sepsis is managed with IV fluids, repletion of electrolytes, IV antibiotics, and IV insulin. 3.Monitoring: This can include monitoring abnormal vital signs, physical exam findings, laboratory studies, or imaging studies. In patients who have an abnormal exam finding, you should make sure to check that the abnormal finding has resolved or improved after therapy has been instituted. a.A patient with tension pneumothorax should have blood pressure, heart rate, oxygen saturation, and respiratory rate monitored until the condition has stabilized. b.A patient with diabetic ketoacidosis and sepsis should have cardiovascular status monitored and should have glucose, electrolytes, and ABG monitored during therapy. c.A child who presents with asthma should have pulse oximetry and a repeat chest/lung exam ordered after therapy to monitor respiratory status. d.A pregnant patient who presents with eclampsia and fetal distress should have a blood pressure monitor, cardiac monitor, fetal monitor, and monitoring of urine output. 4 I—INTRODUCTION 4.Timing: This can vary depending on the severity of each case, but it is important to make sure to complete diagnosis and institute management within a reasonable amount of simulated time. In general, patients who present acutely to the ED should be managed within 1 to 2 hours, and patients in the office should be managed in several hours to days. a.A woman who presents to the ED with diabetic ketoacidosis and sepsis should be diagnosed and have therapy instituted within 1 hour. b.A child who presents to the office with shortness of breath from asthma should have therapy instituted on the first visit within 12 hours of simulated time. c.A pregnant woman who presents to the ED with eclampsia and fetal distress should be managed within 1 hour. d.A woman who presents to the ED with ascending aortic dissection should be managed within 2 hours. 5.Sequence: Even though in many cases you may know the diagnosis from the history, it is important to remember that each case should be managed in an appropriate sequence. Do not skip too early to a treatment if the diagnosis has not been adequately confirmed or if the patient has not been stabilized. Although you may order the correct treatment for the patient, you will lose points if your management is not in an appropriate sequence. a.A patient with ascending aortic dissection should be managed as follows. If you jump too early to a diagnostic imaging study or surgical consult before you have stabilized the blood pressure, you will not score the maximum points. 1)Monitoring (blood pressure monitor, cardiac monitor, pulse oximetry) 2)Targeted exam, including chest and heart 3)Initial diagnostic studies, labs, IV antihypertensive and opiate medications 4)Check blood pressure has improved 5)Chest imaging (such as chest CT) for confirmation of diagnosis 6)Advance to results of imaging confirming the aortic dissection 7)Open heart surgery or consult thoracic surgery b.A patient with eclampsia and fetal distress should be managed as follows. If you order fetal delivery too early before stabilizing the blood pressure, you will not score the maximum points. 1)Monitoring (blood pressure monitor) 2)Exam 3)CBC, BMP, LFT, PT/PTT, urine output, IV magnesium, IV antihypertensive, fetal monitor 4)Advance clock for lab results to rule out DIC and make sure seizures and blood pressure have stabilized 5)Fetal delivery with cesarean section or ob-gyn consult after the patient is stabilized 6.Location: For many cases, location will not be a significant component of the score. Most office patients can be managed as outpatients, and many ED patients can be managed in the ED within the time frame of the case. However, for some cases, patients will require a change in setting, such as an office patient who may need to be transferred to the ED or inpatient unit for optimal diagnosis and management. a.A patient with diabetic ketoacidosis and sepsis should be initially managed in the ED and then changed to the ICU for monitoring. b.A patient who presents to the office with unstable vital signs or requiring IV fluid, IV medications, or a substantial workup and therapy will need to be transferred to the inpatient unit. 5 1—PRIMUM® CCS SOFTWARE CCS Primum® Software Management Options INTERVAL HISTORY OR PHYSICAL EXAMINATION n n n or many cases, particularly in the office setting, management will begin with a physical F examination. A full physical exam takes 15 minutes. For unstable patients, try to limit the initial exam to about 5 minutes or less. Each portion of the exam takes 1 minute except for HEENT, genitalia, and rectal, which take 2 minutes each. (To illustrate how the CCS may not match reality—a full neuro/psych exam takes 1 minute!) Table 1.1 shows how a normal examination is presented on the CCS with some variations for men, women, and children. It is important to be familiar with how a normal exam looks on the CCS so it is easy to find abnormal results quickly, particularly if you have to read through a long full physical exam. The exam results will change after you do some intervention; therefore, remember to recheck any abnormal exam findings after therapy is instituted.

Instead of entering “Complete blood count,” “Basic metabolic profile,” “Liver function panel,” “arterial blood gases,” and “electrocardiography,” it is quicker and easier to enter “CBC,” “BMP,” “LFT,” “ABG,” and “ECG.” The software recognizes both the full names and abbreviations. n A single order can be recognized in multiple ways. n For medications, brand and generic names are recognized. You can order “Bactrim” or “trimethoprim and sulfamethoxazole.” However, on the order sheet, only the generic name will show up. For medications, you don’t have to enter the dose or worry about tapering, although you have to enter the route of administration and whether it is one time or continuous. n An imaging study can be ordered by the body part, modality, or abbreviation. You can order “Abdominal ultrasound,” “Ultrasound, abdomen,” or “US, abdomen.” On the order sheet only “US, abdomen” will appear no matter how you choose to order it. n For lab tests, you can order by test name or specimen type. You can order “Sputum culture,” “Culture, bacterial, sputum,” or “Bacterial culture, sputum.” On the order sheet, it will show up as “Bacterial culture, sputum” no matter how you order it. n Review orders. n The order sheet includes any medications the patient is on at the start of the case as well as any orders you enter during the case. n For some cases, it will be important to review and cancel medications at the start of the case. You can cancel orders by clicking on them. n The order sheet will also list the report times for the various orders you enter. This can affect how you advance the clock and if you want to add or change any orders as you receive results. n Review prior progress notes, vital signs, lab reports, imaging, other tests, and treatment records. n After an order has been entered and reported, it is removed from the order sheet and placed into its appropriate category. This can be helpful to review any examination findings or diagnostic studies that were previously abnormal to make sure you remember to repeat those to confirm improvement. OBTAIN RESULTS OR SEE PATIENT LATER The Obtain Results button is for advancing the clock. There are four options to advance the clock. n On n This allows you to follow up with a patient on a specific date. You can choose the day on the calendar and enter a specific time. This is best for a stable office patient for whom you might order a panel of tests that take 2 to 3 days for results. You can look at the order sheet to see when results are reported and then reschedule the patient after the last result. 1—PRIMUM® CCS SOFTWARE n 7 In his allows you to follow up in a specific number of days, hours, or minutes. This is simiT lar to the “On” button but is used more for an office or ED patient for whom a panel of tests was ordered, and you may want to follow up in 30 minutes or 1 hour to see results of a group of tests before deciding further management. With next available result n This is used more for unstable patients whose condition could change rapidly and you would like to advance the clock relatively slowly with each result as it comes in. Call/see me as needed n This is generally used in the office setting after you have completed management. The clock will advance on its own, and either the software will give you a patient update or the case will end. n n n CHANGE LOCATION The CCS Primum® software offers five locations: n Emergency department n Office n Inpatient unit n Intensive care unit n Home The majority of cases will start in either the office or ED setting. Occasionally, you may see a patient in the inpatient unit who was already admitted for another condition. In the office or ED setting, keep in mind criteria that would require changing location to the inpatient unit or ICU rather than discharging or treating from home. Although there is a long list of potential reasons for admission to the hospital, the following should serve as a general guide: n Unstable vital signs: high fever, hypotension, hypertension, bradycardia, tachycardia n Respiratory distress requiring oxygen n Suspected child or elder abuse n Failure to thrive n Monitoring of vital signs, fetal heart rate, lab results, or imaging results required n IV administration of fluids, medications, or antibiotics required n Invasive or surgical procedure required n Severe trauma causing fracture or acute injury n Suicidal or psychotic patient with potential for harm to self or others Patient Updates and Case End Each case generally has one or two patient update screens to let you know how the patient is responding to your management. If you get a patient update screen showing the patient is doing worse, then reassess your diagnosis and management. When a case ends, you are given 2 minutes to: n Delete any orders you want canceled n Add orders to be done now n Add orders relevant to the patient’s “current” condition to be done in the future At the end, you should review the orders you have placed, and if you remember something that you missed previously, this is your last chance to try to score some points. Also, some orders not appropriate in the time frame of the case but appropriate for the patient’s condition should be placed. For example, if the case ends on a patient with an acute problem, such as diabetic ketoacidosis, and you want to counsel the patient regarding diabetes education or advise him or her to stop smoking, that can be ordered at the end for a later time period. C H A P T E R 2 Tips and Strategies Below is a list of the top 10 tips and strategies for maximizing your score on the CCS. 1.Learn how to manage cases by chief complaint. Patients in real life and in the CCS cases do not present with myocardial infarction, hypothyroidism, or tuberculosis; instead, they ­present with shortness of breath, fatigue, or cough. This is the main reason why this book is ­organized by chief complaint. When a patient presents with abdominal pain, there are 20 or more possible diagnoses. Developing a strategy for how to handle CCS cases by chief complaint is essential to doing well. 2.Create a reference sheet during the exam. It is very difficult to remember the numerous orders and workups that go into each case. Often, during the rush of the actual exam, it is difficult to remember common orders that would normally be second nature to you. For example, it is not uncommon during the actual exam to forget to order an ECG or troponin in a patient who presents in the emergency department with chest pain. For this reason, you may find it useful to create a reference sheet to use during the exam. During the exam, you are given two double-sided worksheets to use as you wish. Before beginning the CCS cases, create your reference sheet on one of the worksheets. The reference sheet should contain common orders for patients who present with common presenting symptoms, such as chest pain, abdominal pain, shortness of breath, fatigue, altered mental status, cough, diarrhea, bleeding, and vaginal discharge. Refer to Table 3.1 for a sample reference sheet. Practice the cases in this book and on the CCS Primum® software with a reference sheet. Having a reference sheet to help guide you through the cases will be a definite advantage during the exam. 3.Learn to how to create a CCS matrix. CCS cases are graded according to six domains: diagnosis, therapy, monitoring, timing, location, and sequencing. Each case in this book is analyzed according to these domains. Having a good understanding of these domains for each case will help in your management. Often, the diagnosis for a particular case will be known early in the case, during the history or initial exam. However, much of your score is determined after the diagnosis is known; therefore, it is important to have a good understanding of how each case may be graded according to each of the domains. For some test takers, just having a mental awareness of these domains is sufficient. For others, it may be helpful to use the blank worksheet provided during the exam and fill in each of the domains as you work through the case and after you have figured out the diagnosis. 4.Practice cases on the USMLE Primum® software. Having a good understanding of the software can have a dramatic impact on your score. Download the USMLE Primum® CCS software from the usmle.org website and practice the six CCS case that are provided. Compare what you did on the software with the recommendations in this book. After you feel comfortable managing those cases, try to manage the cases in this book using the ­Primum® software. Read the first page of a case and then go to the software and pretend you were managing the patient on the actual software. Compare what you did with what you see on the second page of the case. 5.Don’t narrow your differential diagnosis too soon. Although in many cases you can figure out the diagnosis from just the initial history, be careful not to narrow your differential too soon. For example, you may get a case of a patient who is a recent immigrant from Latin 2—TIPS AND STRATEGIES 9 America and presents with a cough. Although your first thought might be tuberculosis, the patient in the case may actually have Hodgkin lymphoma or lupus pleuritis. Similarly, you may get a case of a child who presents with bruising that you may first think is due to child abuse but may actually be hemophilia. 6.Watch for CCS cases that have two diagnoses. In some cases, you may be able to figure out the primary diagnosis relatively quickly and easily; however, the patient may have a second important diagnosis that may go undetected if a complete workup is not performed. For example, you may be presented with a patient who has diabetic ketoacidosis, but a ­complete workup shows the patient also has sepsis or an acute myocardial infarction. In addition, it is not uncommon for female patients to present with one diagnosis but also have an undiagnosed pregnancy. For example, you may be presented with a female patient who has a UTI or a breast mass that turns out to be carcinoma, but checking a urine HCG level also shows that the patient is pregnant, which may alter your therapy. 7.Don’t rely on consultants too much. Typically, consultants are not very helpful in the CCS cases. Because the cases are designed to evaluate your management skills, often they will tell you to manage the patient as you think appropriate. The only exception is when it comes time to perform a surgical procedure. Because you should assume you are managing the patient as a primary care physician, a surgical consult ordered at the appropriate time will result in the consultant taking the patient for the procedure. Alternatively, you could order the procedure yourself. If you encounter a situation in which you would normally order a consult in real life, then you should probably go ahead and order it; just don’t expect it to be very helpful. 8.Be careful about practicing online CCS cases. There are a variety of online options for practicing CCS cases from third-party vendors. In some instances, practicing online cases can help develop key skills, such as practicing lots of cases, remembering orders from ­memory, and developing stamina under similar test-taking conditions. However, online sources can never replicate the actual software and may get you used to options and ­strategies that do not apply to the real software. In most cases, you are probably better off saving your money for a little celebration after you finish the exam. 9.Get plenty of rest the night before. The CCS cases are on the second day of testing, and depending on how the first day went, you may be feeling stressed the night before. Try to put any bad feelings from the first day out of your mind (I know, easier said than done) and get adequate sleep the night before. The test is hard enough without having to fight fatigue, headache, tiredness, or memory lapses from lack of sleep. 10.Have fun. Compared with the monotony of hundreds of multiple-choice questions, the CCS cases are actually an enjoyable change during the exam. Some people even find them fun. They are even more fun when you know what you’re doing. Hopefully, most of the cases you encounter on the exam will come directly from this book. However, as long as you are well prepared, it really shouldn’t matter which cases you see on the real exam. C H A P T E R 3 Reference Sheet On the following page, a sample reference sheet (Table 3.1) is provided to help with recall of common orders. There are roughly 2500 unique orders in the CCS software. Because many orders can be placed with different terminology (e.g., “BMP” can also be ordered as “Basic metabolic panel”), there are a total of 12,000 orders that are possible. The reference sheet attempts to narrow down that list to the most important 100 to 150 orders for diagnosis. During your preparation, use the reference sheet as you practice cases. Feel free to add, remove, or change any orders on the reference sheet to your own preferences. You may find it useful to try to memorize a reference sheet before the actual exam. On day 2 of the exam, recreate from memory the reference sheet on the blank worksheet provided to you before you begin the CCS cases.

What is the suspected diagnosis, and what are the next steps in management? 14 I—INTRODUCTION Case #1: Tension Pneumothorax Keys to Diagnosis n n n To practice this case, go to USMLE Case #1 in the CCS Primum® software. Although these patients can present spontaneously, they can also present after trauma to the chest. Symptoms include sudden, severe chest pain; dyspnea; sweating; anxiety; and fatigue. Vital signs show hypotension, tachycardia, and tachypnea. Examination shows decreased breath sounds and hyperresonance over the affected side, tracheal deviation to the opposite side, weak peripheral pulses, and faint heart sounds. The diagnosis should be made on the physical exam results. Although the diagnosis can be confirmed with FAST ultrasound or portable chest X-ray, treatment should not be delayed for these studies. Management n n n eedle thoracostomy should be ordered after absent breath sounds are discovered. “Whoosh N of air” confirms the diagnosis. Tube thoracostomy (also ordered as “Chest tube”) should be ordered immediately after needle thoracostomy to prevent recurrence. Chest X-ray should be ordered after thoracostomy to confirm tube placement. Oxygen, IV fluids, and pain relief with morphine are optional during the time frame of this case but are recommended. End orders, including routine labs, troponin, and counseling, are also optional and unlikely to add significantly to your score but are recommended especially if the history shows the patient is a smoker or overweight.

Look for a patient with a chronic history of bilateral, symmetric swelling and tenderness in distal joints (hands, wrist, feet, knees). In addition, there are generalized chronic symptoms such as fatigue and weakness. On exam, affected joints will show warmth, swelling, tenderness, and decreased range of movement. Diagnosis is supported by rheumatoid factor, ESR and cyclic citrullinated antibody. CBC, ANA, arthrocentesis, and synovial fluid studies should be ordered to rule out other ­differentials. Management n n n SAID (ibuprofen) or corticosteroid (prednisone) to reduce pain and inflammation N DMARDs (methotrexate) to slow joint damage and improve joint function. Monitor CBC, LFT, and renal function (BMP) every 3 months on methotrexate. Avoid methotrexate if pregnancy is a possibility; use etanercept or sulfasalazine instead. Advise patient to exercise or consult physical therapy to prevent joint deformity and loss of joint function.

The pain is a dull ache that does not radiate. The pain has been worsening and is now rated a 6 on a 10-point scale. There is no history of dark stools, vomiting, or diarrhea. She notes occasional episodes of shaking chills and increasing fatigue. She has had one to two episodes of shortness of breath on exertion in the past few days. There is no history of cough or chest pain. •Past medical history includes diabetes mellitus treated with metformin. •Family history, social history, and review of systems are unremarkable.

What is the suspected diagnosis, and what are the next steps in management? 30 II—CCS CASES BY CHIEF COMPLAINT Case #7: Pneumonia Keys to Diagnosis n n n Although typical symptoms include cough, dyspnea, or hemoptysis, on the CCS, look for an atypical presentation, such as abdominal pain in an elderly or diabetic patient. Additional symptoms include fatigue and exercise intolerance. Vital signs may show fever, tachypnea, and tachycardia. On chest exam, look for rales, rhonchi, decreased breath sounds, or dullness to percussion on the affected side. Chest X-ray, PA/lateral is the standard for diagnosing pneumonia. On the CCS, an abdominal X-ray acute series includes a PA chest X-ray that will also detect lower lobe pneumonia. Sputum studies can be performed if the patient has a productive cough. Lab tests (CBC, BMP, blood cultures) are generally not needed for diagnosis unless the patient meets criteria for admission. Management n Antibiotic therapy is the mainstay of treatment. Several options exist, but in general: For a generally healthy outpatient, use an oral macrolide (azithromycin). n For outpatients with a comorbid condition (CHF, diabetes, alcoholism, malignancy) or have been on an antibiotic within 90 days, use an oral fluoroquinolone (ciprofloxacin). n For a patient admitted to the hospital, use an IV fluoroquinolone (levofloxacin). Decide whether to admit the patient. n If the vital signs are normal, pulse oximetry is normal, and chest X-ray shows localized involvement, then outpatient therapy is adequate. n If the patient has comorbid conditions and abnormal vital signs such as hypotension or tachypnea requiring oxygen, IV fluids, or IV antibiotics, then admit to inpatient unit. n If the patient is septic with severe hypotension, admit to ICU. n n OPTIMAL ORDERS DIAGNOSIS THERAPY MONITORING LOCATION TIMING SEQUENCING ADDITIONAL ORDERS •Exam: lungs, abdomen •Exam: complete •Chest X-ray, PA/lateral (or Abdominal •CBC, BMP, Blood culture, if X-ray, acute series) admitted to hospital •Antibiotic: •Acetaminophen, oral •Azithromycin, oral (if outpatient and •Reassure patient healthy) •Advise patient, no smoking •Ciprofloxacin, oral (if outpatient but comorbid conditions) •Levofloxacin, IV (if admitted to hospital) •Oxygen (if pulse oximetry reduced) •Pulse oximetry •Admit to inpatient unit if decreased pulse oximetry or if patient requires oxygen, IV fluids, or IV antibiotics. •Diagnosis and management should be instituted within 2 hours of simulated time.

Rectal Sphincter tone normal. No masses or abnormality. Stool brown; no occult blood. What is the suspected diagnosis, and what are the next steps in management? Case #9: Acute Pancreatitis Keys to Diagnosis n n n Look for a patient with severe abdominal pain, epigastric or left upper quadrant, which often radiates to the back. Additional symptoms include nausea, vomiting, anorexia, and diarrhea. Look for a history of gallstones or alcohol use. Vital signs show fever and tachycardia. On exam, abdominal distention with tenderness and guarding in the upper quadrant is often seen. Bowel sounds are typically reduced because of ileus. No occult blood on rectal exam. Abdominal CT scan is the radiologic test of choice in severe acute pancreatitis for assessing complications and providing prognostic information. Abdominal ultrasound and X-ray are less useful in this setting. Lab tests such as amylase, lipase, LFT, and others listed below provide additional support and help determine prognostic information. Management n n n n Provide aggressive supportive care: Oxygen, NPO, IV fluids, Monitor urine output, Nausea control (Promethazine) and pain relief-Hydromorphone hydrochloride (Dilaudid). Antibiotic use is controversial. Currently not recommended for prophylaxis; recommended only if acute necrotizing pancreatitis is present. Endoscopic retrograde cholangiopancreatography (ERCP) if imaging and laboratory studies consistent with severe acute gallstone pancreatitis.

Crisis is often precipitated by dehydration, infection, pregnancy, stress, or cold weather. Vital signs will show fever with acute chest syndrome. Examination is generally unremarkable. Order chest X-ray looking for acute chest syndrome (pulmonary infiltrates on CXR, chest pain, and fever). Order sputum studies if productive cough. If CBC shows severe anemia, order reticulocyte count looking for aplastic crisis (low reticulocyte count). In older patients, consider abdominal ultrasound to evaluate for gallstones. Management n n n n n n Treatment is mainly supportive: hydration with IV fluids, pain control with morphine and NSAIDs, oxygen if hypoxia, incentive spirometry. Hydroxyurea is used in the chronic setting after initial management to prevent future attacks. Transfusion if significant anemia or thrombocytopenia present (aplastic crisis). Empiric antibiotics in acute chest syndrome (Azithromycin). Hematology consult optional. If gallstone cholecystitis present, consider surgical consult.

The pain typically is cyclical, lasting 10 to 15 minutes, and the patient often draws their legs up to the abdomen. Additional symptoms include lethargy; diarrhea, which may be bloody; and recent viral infection. Examination may show a “sausage-like” abdominal mass in one quadrant (usually right upper quadrant). Also, look for bloody or “Currant jelly” stools. Initial screening with ultrasound or abdominal X-rays. Ultrasound is more commonly used and will more clearly identify the intussusception. X-rays may show a soft tissue mass and dilated loops of bowel (obstruction). If ultrasound or X-ray results are normal, intussusception is unlikely. CBC and BMP for screening. Management n n n arium enema is both diagnostic and therapeutic. Note: air enema is not an option on the B CCS. 24-hour observation in hospital after reduction is recommended.

History may show multiple sexual partners, prior STI, or lack of condom use. Vital signs show a fever. Examination shows purulent vaginal discharge, adnexal tenderness, or cervical motion tenderness. Order hCG to rule out pregnancy. Abdominal or transvaginal ultrasound may show fallopian tube dilation or abnormalities in the ovaries. MRI has higher sensitivity than ultrasound but is more costly. Order studies for sexually transmitted diseases: chlamydia, gonorrhea, Trichomonas, HIV, hepatitis. Management n n n Decide whether to admit: tubo-ovarian abscess, pregnant, immunodeficient, severe illness, noncompliant. Antibiotic treatment should be effective against gonorrhea and chlamydia + anerobes. If inpatient, use cefotetan IV or cefoxitin IV + doxycycline oral. Stop IV meds 24 hours after improvement, but continue Doxycycline for 14 days. If tubo-ovaian abscess present, add Metronidazole, oral for 14 days. If outpatient treatment, use ceftriaxone IM single dose + doxycycline oral for 14 days + metronidazole oral for 14 days.

What is the suspected diagnosis, and what are the next steps in management? 54 II—CCS CASES BY CHIEF COMPLAINT Case #19: Peptic Ulcer Disease with Perforation Keys to Diagnosis n n n For peptic ulcer disease, look for epigastric pain that is gnawing or burning, occurring after meals, and that may be relieved by foods or antacids. Other symptoms include belching, bloating, heartburn, melena, fatigue from anemia, and weight loss. In patients with perforation, look for more severe, sharp abdominal pain with abnormal vital signs. On exam, peptic ulcer disease may show mild tenderness. If perforated, abdominal rebound tenderness, guarding, and rigidity are present. Stool occult blood positive. Endoscopy is the diagnostic test of choice in peptic ulcer disease, however should not be used if perforation suspected. A chest X-ray may show free abdominal air in perforation. Abdominal CT scan is typically used as the primary diagnostic modality in perforation. Baseline testing for CBC, BMP, type and crossmatch, PT/PTT, LFT, amylase, and lipase is recommended. Testing for H. pylori is generally performed. Management n n For nonperforated ulcers: treat H. pylori (PPI + two antibiotics; e.g., omeprazole + clarithromycin + amoxicillin); avoid NSAIDs, alcohol, and smoking. For perforation and an unstable patient: IV access and normal saline, ABCs (intubation if needed), nasogastric tube suction, urgent surgical consult, IV proton pump inhibitor (e.g., Pantoprazole sodium), IV antibiotics (e.g., metronidazole + gentamicin) and eventual treatment of H. pylori.

None 5—ABDOMINAL PAIN 61 Abdominal Pain—Key Points n n n n bdominal pain is commonly tested on the CCS. Expect one or more CCS cases of a A patient presenting with abdominal pain. In most cases, the diagnosis should be evident from the history and initial examination. Additional diagnostic studies should confirm the suspected diagnosis and rule out other diagnoses. Some general rules to follow in patients with abdominal pain: n If vital signs are abnormal, begin with monitoring orders. n If the patient is in acute distress, perform only a limited physical exam. n If the patient is a reproductive-age woman, check urine hCG and avoid CT for ultrasound if possible. n If the patient is in severe pain, order pain relief early. n Do not order surgical consult too early. A surgical consult may not do anything if you order that up front but may take the patient to surgery after you have confirmed the diagnosis. In patients who present acutely, when the clock is advanced, patient update screens will happen fairly quickly to help you determine whether you are managing the patient correctly. If you get a negative update on a patient, reevaluate whether your suspected diagnosis is correct.

None 6—FATIGUE 87 Fatigue—Key Points n n n n wide variety of diseases can present with fatigue. Common causes to consider include A cancer, endocrine disorders (diabetes, hypothyroidism), anemia, and blood loss (peptic ulcer disease, colon cancer). A general panel of tests to keep in mind for patients who present with fatigue includes: n Fasting glucose n TSH n CBC n BMP n LFT n Depression index n Urinalysis Most of the screening studies are resulted in 1 to 2 days, so initial management often involves rescheduling a stable patient for a return visit. However, for children with fatigue, it is generally best to get a stat CBC on the first office visit (1 hour), then plan for additional follow-up depending on the results. Some patients will have more than one diagnosis, so even if one diagnosis is evident on the initial presentation, it is generally useful to screen for other causes of fatigue (e.g., a patient who appears to have lead poisoning may also have iron deficiency anemia).

None 7—CHEST PAIN 97 Chest Pain—Key Points n n n or most cases, the diagnosis should be evident from the history. However, even if you are F sure of the diagnosis, you still need to rule out other differentials and confirm the diagnosis. For example, you may know the patient has aortic dissection, but you still need to rule out myocardial infarction, pulmonary embolism, and so forth Important diagnostic studies to consider in patients who present with chest pain include: n ECG, 12-lead n Chest X-ray, PA/lateral n Troponin (“cardiac enzymes” can also be ordered, but take longer and CPK fractions do not really add much more to the troponin results in most cases). n D-dimer n CBC n BMP For cases needing urgent surgical intervention, such as aortic dissection, make sure to stabilize the blood pressure and pain before ordering surgical consult or surgery.

You may see a history of depression or prior suicidal attempts. Vital signs show hypotension, bradypnea, and tachycardia. On exam, look for dilated pupils (mydriasis) and absent bowel sounds. ECG typically shows QRS prolongation, tachycardia, and sometimes AV block. The diagnosis should be made before serum or urine toxicology results. Assess baseline labs: CBC, BMP, and ABG. Rule out other causes in the differential and other coingested substances. Management n n n Treatment is mainly supportive. ABCs—intubate if needed, oxygen. IV fluids for hypotension. IV sodium bicarbonate if QRS prolonged or evidence of cardiotoxicity. Nasogastric tube may show pill fragments. Decontamination with “activated charcoal” within 2 hours of ingestion may be considered. “Gastric lavage” within 1 hour of ingestion may be considered for serious toxicity.

What is the suspected diagnosis, and what are the next steps in management? 104 II—CCS CASES BY CHIEF COMPLAINT Case #41: Benzodiazepine Overdose Keys to Diagnosis n n n Look for a patient that is confused, disoriented, somnolent or has loss of consciousness. Vitals may show hypotension and bradypnea. On exam, HEENT shows vertical nystagmus, and neurologic exam shows that the patient is not oriented with diminished muscle strength and reflexes. Diagnosis is based on history and exam. ECG showing no QRS prolongation should make tricyclic antidepressant overdose less likely. Urine or blood drug testing can confirm the diagnosis, but for the CCS, treatment should be instituted before results of toxicology tests. Management n n n Supportive care is the mainstay of therapy. ABCs—monitoring vital signs, oxygen, IV fluids, intubation if severe respiratory depression. Nasogastric tube may reveal pill fragments. Decontamination with “activated charcoal” within 4 hours is controversial but may be considered. “Gastric lavage” is generally not recommended. Flumazenil can reverse CNS depression but its use is controversial. Consultation with poison control center, substance abuse unit or psychiatry may be considered.

Often, an associated pneumonia will be present with yellow sputum and fever. Intrathoracic spread of the tumor may present as hoarseness, dysphagia, or stridor. If SIADH is present, look for symptoms of hyponatremia (anorexia, nausea, malaise, muscle cramps, weakness, headache, or irritability). Exam may show features of pneumonia (rales, rhonchi, wheeze, dullness to percussion). Chest X-ray, PA/lateral will provide the first clues to an abnormality. Sputum culture and cytology may provide additional information. Chest CT should be performed for diagnostic and staging purposes. A bronchoscopy or mediastinoscopy with cytologic evaluation may be needed for diagnosis. Management n n n n Consult surgery, hematology/oncology, and radiation therapy. Counseling regarding cancer diagnosis. Staging studies include CBC, BMP, LFT, MRI brain (for metastases), bone scan, and bone marrow biopsy.

The most common symptoms for acute cardiac tamponade are dyspnea, dizziness, chest pain, drowsiness, and palpitations. Vital signs show hypotension, tachycadia and tachypnea. Exam shows diminished heart sounds, distended neck veins, weak pulses. Exam may also show pulsus paradoxus (systolic blood pressure decreases >12 mm Hg during inspiration). Diagnosis is based on Beck’s triad (hypotension, diminished heart sounds, distended neck veins) and should be made on the examination. A FAST ultrasound can help confirm the diagnosis. Other studies, such as chest X-ray (cardiomegaly), ECG (electrical alternans), and echocardiography (pericardial fluid collection) should not delay treatment. Management n n n Pericardiocentesis (automatic consult cardiothoracic surgery) should be ordered as quickly as possible. Supportive care—oxygen, IV fluids, monitor vital signs.

Vital signs show bradycardia, hypotension and tachypnea. On exam, look for signs of heart failure: jugular venous distension, rales, weak pulse, ­peripheral edema. ECG is the diagnostic study of choice. Treatment should be initiated immediately after ECG results. Management n n n Temporary transthoracic pacemaker is the initial treatment of choice. It is preferred over atropine, which may not work if the block is in the His bundle or if wide-complex bradyarrhythmia is present. A permanent pacemaker should be ordered after the patient is stabilized. A transvenous pacemaker is commonly ordered after transthoracic pacemaker in most real-world situations; however, on the CCS, it is optional. Supportive treatments—oxygen, IV fluids, pain relief.

Other symptoms include fatigue, malaise, jaw pain, visual disturbance, and joint pains. Vital signs may show fever. Exam may show scalp tenderness, visual field defects, and decreased joint movements. Diagnosis is based on American College of Rheumatology (ACR) criteria. A score of three or more of the following five features is recommended: Age >50, ESR >50 mm/hr, superficial temporal artery tenderness, temporal headache that is lateralised, positive temporal artery biopsy. Biopsy is often not needed if other features are present, but if desired, should be performed within 1 week after the initiation of corticosteroid therapy. Management n n n For mild to moderate disease, treat with oral prednisone until symptoms resolve and ESR returns to normal. If severe symptoms (visual field defects), treat with IV methylprednisolone. Long term steroids require calcium, vitamin D and bisphosphonate (e.g., alendronate) to prevent steroid-induced osteoporosis. Because of increased risk of aortic aneurysm, order chest X-ray or chest CT if clinical suspicion. Consult ophthalmology and rheumatology, Counseling.

Unlike giant cell arteritis, there is no joint pain, visual disturbances, jaw pain, or fatigue. Often symptoms begin with a rash that may appear like contact dermatitis. On exam, the classic vesicles may not be present on initial exam. Look for rash, then vesicles in a dermatome distribution a few days after initial presentation. Diagnosis is based on history and exam. Workup should rule out other causes, such as giant cell arteritis. Confirmation via tzanck smear, PCR or culture is generally not needed unless the diagnosis is unclear. Management n n n n Episodes of herpes zoster are generally self-limited in immunocompetent patients and ­resolve on their own. Treatment can reduce duration of symptoms and chronic sequelae, particularly in immunocompromised patints and people age >50. Treat pain with NSAIDs, narcotic or Gabapentin. Antivirals (e.g., valacyclovir) can reduce pain, inflammation, and vesicle formation if begun within 48 hours of onset of rash. Varicella vaccine reduces severity and pain caused by herpes zoster in most patients. Cold compresses are useful to break vesicles and remove serum and crust.

Vital signs L show elevated blood pressure and increased BMI if obesity present. Examination is generally unremarkable in primary hypertension. Look for signs of ­secondary hypertension, such as abdominal bruit (renal artery stenosis), heart murmur (aorta ­coarctation), moon facies & truncal obesity (Cushing’s syndrome), malar rash (systemic lupus). Confirm hypertension with repeat blood pressure. Diagnosis focuses on evaluating for the presence of end organ damage, looking at cardiovascular risk factors and ruling out ­secondary causes of hypertension. More specific studies for pheochromocytoma (Urine ­catecholamines), Cushing’s syndrome (dexamethasone suppresion test), Renal artery stenosis (renal artery angiogram), Turner syndrome (karyotype), hyperthyroidism (TSH), adrenal insufficiency (plasma cortisol, ACTH stimulation test) and systemic lupus (ANA) will depend on the individual patient. Management n n n ifestyle modifications are the cornerstone of treatment for hypertension and obesity— L weight loss diet, exercise, along with counseling regarding smoking, alcohol, and safe sex. Medications (e.g., beta blockers or diuretics) should be initiated if blood pressure is ­unresponsive to lifestyle changes or if end-organ damage is present. Symptomatic treatment of any other complaints (e.g., benzoyl peroxide for acne).

Obstructive sleep apnea generally presents in an obese person with snoring, difficulty sleeping and daytime sleepiness. Vital signs may show elevated BMI if obesity, but otherwise are generally unremarkable. On exam, look for jugular venous distention, loud P2, S4, systolic murmur or peripheral edema in pulmonary hypertension. The diagnosis focuses on determining if the pulmonary hypertension is primary or ­secondary to another medical problem. Abnormal studies in pulmonary hypertension can include ECG, Chest X-ray and echocardiography. Evaluation of secondary causes of pulmonary hypertension include sleep apnea study (­polysomnography), ANA for connective tissue disease, TSH for thyroid abnormalities and D-dimer. If ­secondary causes are ruled out, cardiac catheterization confirms increased pulmonary pressure in primary pulmonary hypertension. Management n n For secondary pulmonay hypertension, treat the underlying condition. For sleep apnea, treat with CPAP, weight loss and avoiding smoking and alcohol. For primary pulmonary hypertension, treat with medications (diuretics, vasodilators, coumadin), counseling (diet - low sodium, avoid sports, avoid pregnancy), and oxygen if needed.

Other symptoms include tremor, anxiety, heat intolerance, sweating, and mood swings. Vital signs may show tachycardia. Examination may show exophthalmos, goiter, tremor, or hyperreflexia. Diagnosis is based on initial evaluation with TSH and free T4. Thyroid antibodies and ­radioactive iodide uptake (RAIU) help differentiate Graves’ disease from toxic multinodular goiter. Rule out pregnancy in females. Management n n n Propranolol for tachycardia and other beta-adrenergic symptoms. Methimazole is preferred initial treatment. If the patient is pregnant, use propylthiouracil. Monitor every 1 to 2 months until the patient is euthyroid. Radioactive iodide is preferred for treating hyperthyroidism caused by toxic adenoma or multinodular goiter except in pregnant women. Surgical therapy if other therapies do not work or if obstructing goiter.

Common causes of renal failure include prerenal (hypovolemia, CHF, cirrhosis, sepsis), renal (myoglobinuria, IV ­contrast, or medications such as aminoglycosides, NSAIDs, ACE inhibitors, and COX-2 inhibitors), or postrenal (BPH, stones). Vital signs may show tachycardia and tachypnea. On exam, look for peripheral edema, increased skin turgor and volume status changes. Diagnosis is based on BMP (elevated creatinine, abnormal electrolytes), urinalysis (granular casts in acute tubular necrosis), and urine osmolality (<400 in ATN and postrenal causes, >500 in ­prerenal causes such as hypovolemia). Management n n n If intrarenal cause of renal failure, such as ATN, stop all nephrotoxic medications. IV furosemide is commonly used, but there is little evidence to support its use. Dopamine is no longer recommended. Hemodialysis if severe kidney injury (severe abnormalities in acid-base balance, electrolytes, volume overload or marked uremia). If prerenal cause of renal failure, IV volume expansion with fluids. If postrenal, treat obstruction. Monitor urine output.

What is the suspected diagnosis, and what are the next steps in management? 242 II—CCS CASES BY CHIEF COMPLAINT Case #100: Atrial Fibrillation Keys to Diagnosis n n n Look for the presence of an irregular heart rate typically in the range of 110 to 140 beats/min. Symptoms can include palpitations, fatigue, exercise intolerance, syncope, or ­dizziness, or the patient may be asymptomatic. On exam, look for presence of irregular heart rate and pulse as well as signs of ­hyperthyroidism, heart failure, and valvular heart disease. Diagnosis is based on ECG. If intermittent and not present on initial visit, order Holter monitor. Additional studies should be ordered to look for an underlying cause (e.g., thyroid dysfunction) and to determine if any heart failure is present. Management n n n Treat any underlying causes, such as thyroid dysfunction if present. The cornerstone of management is rate control and anticoagulation. For rate control: If hemodynamically stable, cardiology consult and initial management with a calcium channel blocker (verapamil) or beta-blocker (atenolol). If hemodynamically unstable, admit to emergency department and consider cardioversion with sedation (e.g., midazolam) if transesophageal echocardiography shows no thrombus and anticoagulation started. For anticoagulation, use warfarin or if warfarin contraindicated, use aspirin and clopidogrel.

Look for thick, white, curdlike “cottage cheese” vaginal discharge. Patients may have history of immunosuppression (especially diabetes) or antibiotic use, but not necessarily a history of multiple partners or unprotected sex. Vaginal exam may show edema, beefy red mucosa, and thick white discharge. Diagnosis can be made by exam, wet mount, or KOH prep. Pregnancy test should be ­performed. Management n n n Topical azoles (miconazole or butoconazole) show better cure rates than nystatin. Treatment is typically 7 days. Counsel patients to wear loose-fitting underwear to reduce the warm, moist environment that promotes Candida growth. Treatment of partners is generally not necessary. If history of recurrent candida infections or if other infections present, evaluate for immunosuppression, such as diabetes or HIV.

Because trichomoniasis is a sexually transmitted infection, there usually is a history of multiple partners or unprotected sex. Examination may show vulvar erythema, vaginal discharge, “strawberry” cervix, or lower abdominal tenderness. Vaginal wet mount is the diagnostic test of choice to view motile organisms. pH is typically >4.5 but not specific. Vaginal culture is sensitive and specific but takes more time. Management n n Metronidazole for 7 days is the treatment of choice. Counseling to avoid alcohol and sex during treatment is recommended. Treatment of sexual partners is also recommended to avoid reinfection.

For most patients, order the rapid 5-minute tests (vaginal pH, wet mount, KOH prep, hCG; Table 20-1). Vaginal Gram stain is optional but can be helpful in the diagnosis of bacterial vaginosis. For patients who have had multiple partners or unprotected sex, consider adding tests for HIV, hepatitis, gonorrhea, and chlamydia. For patients who have not had a recent evaluation and meet criteria, consider ordering a Pap smear and/or HPV testing. If a patient has a positive hCG test result and is pregnant, the treatments remain the same but include additional pregnancy management (see Case #109). If a patient has recurrent Candida infections or signs of infection in other areas, order a follow-up HIV test if the rapid test result is negative and order a fasting glucose for diabetes mellitus. (See case #59 and Case #25.) If HIV positive, manage Candida infection with oral fluconazole.

Signs of pregnancy may not be obvious, other than lengthened menstrual period. On examination, look for evidence of vaginal discharge or other infections. Signs of pregnancy, such as breast tenderness and enlarged uterus, may be present. Diagnosis is based on urinalysis and urine culture. Urine hCG result should be positive if the patient is pregnant. If pregnant, order routine initial pregnancy evaluation: CBC, type and screen, RPR, rubella, Pap smear, HIV, hepatitis B, gonorrhea, chlamydia, and varicella.

Family history of breast cancer may or may not be present. On exam, the mass is typically firm and mobile. Ultrasound and biopsy (or aspirate) will generally lead to the diagnosis. Consider getting a urine hCG because pregnancy may affect the decision to order mammography. (In general, mammography is regarded as safe during pregnancy; however, it has a higher false-negative rate. For the CCS, it is better to avoid mammography if the patient is pregnant.)

The presentation typically is in an older female, but can also present in a younger woman. The mass is typically firm and nonmobile. On exam, look for a firm, nonmobile mass. Also, in a reproductive-age patient, watch for signs of pregnancy, such as bilateral breast tenderness or an enlarged uterus. Mammography, ultrasound, and biopsy should lead to the diagnosis. If the patient has irregular menses or signs to suggest pregnancy, order a urine hCG and avoid mammography. Management n n n Surgery, chemotherapy, and radiation are all used for management depending on the stage. If the patient is pregnant, radiation and chemotherapy are generally avoided, and surgery is the mainstay of therapy. Counseling regarding cancer diagnosis. Order routine pregnancy labs if patient is pregnant.

Look for increased temperature on initial vital signs. The child may have no other symptoms or may complain of nausea, headache, sore throat, runny nose, itching, or arthralgia. On the CCS, a parent or caregiver may appear pushy or upset, encouraging you to give an antibiotic. The initial exam is often unremarkable. The classic “slapped face” rash may not be present until subsequent follow-up examination. The typical workup for a child with fever is based on age, temperature, and whether he or she ­appears toxic. The diagnosis of erythema infectiosum is clinical. Imaging and labs are generally not needed. Management n n n Treatment is supportive. The illness is typically self-limited, lasting 1 to 2 weeks. Do not give antibiotics. Follow-up every 24 to 48 hours to monitor temperature, symptoms, and exam. OPTIMAL ORDERS ADDITIONAL ORDERS DIAGNOSIS •Exam: Skin, HEENT.

On vital signs, look for high temperature with possible hypotension or tachycardia. On exam, look for purpuric rash on the skin or extremities. Also look for nuchal rigidity, papilledema, or dilated pupils on the HEENT exam and bulging fontanelles in infants. CT or MRI of the head if increased intracranial pressure, coma, or neurologic deficits. CSF studies will lead to the diagnosis. On CSF, look for opening pressure >100 mm Hg, low glucose, high protein, cell count with predominant neutrophils, and positive meningococcal antigen. On Gram stain, look for gram-negative diplococci (Neisseria meningitidis) or grampositive cocci in pairs (Streptococcus pneumoniae) if pneumococcal meningitis. Management n n n Empiric antibiotics should be started after cultures and before results of studies. Several options are available. One option is to use a third-generation cephalosporin (e.g., ceftriaxone) plus Vancomycin as empiric therapy. Acetaminophen to help reduce fever. Bacterial meningitis should be reported to the public health department. Admission to the inpatient unit or ICU. Monitor temperature and vital signs.

Typical symptoms, such as ear pain, pulling on the ear, and difficulty hearing, may not be present. Vital signs show fever. On examination, look for tympanic membrane abnormalities on HEENT exam. Unless the patient appears toxic, additional lab and imaging tests are generally not needed. Management n n n Antibiotics: If younger than 2 years of age, use antibiotics for 5 to 7 days. If older than 2 years, can use observation if nonsevere illness or antibiotics if more severe illness. Amoxicillin is the first-line drug of choice. If no response in 3 days, change to amoxicillin/clavulanate or second-generation cephalosporin (e.g., cefuroxime). Supportive: fever reduction as needed, hydration, and avoid irritants (tobacco smoke). Treat as outpatient unless there is evidence of meningitis or sepsis.

For pediatric patients 1 month to 3 years of age who present to the office with a fever >39° C and appear nontoxic, in general, order a CBC, urinalysis, and urine culture (Table 22-1). The results of the CBC and urinalysis can be seen at the first visit. If the CBC shows WBC >15,000/mm3 or ANC >10,000/mm3, consider changing location to inpatient unit, completing workup with blood cultures and CSF studies, and starting antibiotic therapy. If the WBC and ANC are not elevated, follow up in 24 hours and manage with observation.

On exam, look for high-arched palate, widespread nipples, delayed breast and pubic hair development, heart murmurs, hypoplastic nails, nevi, and lymphedema. Diagnosis is made by chromosome analysis, which reveals 45,XO karyotype. Although buccal smear for Barr bodies is an option on the CCS, it is no longer commonly used. Echocardiography may show a bicuspid aortic valve, coarctation of the aorta, or aortic stenosis. Other comorbid conditions to look for include horseshoe kidneys, hypothyroidism, diabetes ­mellitus, hearing loss and osteoporosis. Management n n n Medications: Growth hormone therapy for short stature (if bone age <14 years), Estrogen therapy for puberty (assess LH and FSH before starting), Calcium and Vitamin D therapy for Osteoporosis.

Look for a history of recent infection or new medication. Since it is X-linked recessive, look for a family history of affected male members. On exam, evidence of jaundice should be present with scleral icterus. Splenomegaly or hepatomegaly may be present. CBC shows normocytic anemia with presence of bite cells. Reticulocytes are increased. Laboratory studies show evidence of hemolysis: increased LDH and bilirubin and decreased haptoglobin. Diagnosis is confirmed by evaluation of Heinz body stain or glucose-6-phosphate dehydrogenase ­activity. Management n n n Discontinuation of the triggering agent is the primary treatment. If a new medication was recently started (typically an antibiotic), cancel it. The primary therapy is supportive with bed rest. If severe anemia, admit to inpatient unit for IV fluids, oxygen and possibly transfusion. Hemolysis is generally short lived, and most patients do not require transfusion.

At delivery, the patient had normal Apgar scores, and no complications were reported. The mother of the infant is a 38-year-old woman who has not had any prenatal care. This is her first child. The mother reports difficulty getting the infant to latch on to her nipples and feed. The infant has vomited every time feeding has been attempted and the vomitus was noted to be billous. •Family history and review of systems are unremarkable. INITIAL MANAGEMENT Exam •General, Skin, HEENT, Chest, Heart, Abdomen, Genitalia, Extremities, Neuro Initial Results: Advance to results of physical exam Physical Exam Results (Pertinent Findings) General Newborn infant, crying. Skin Normal turgor. No nodules or other lesions. Hair and nails normal. HEENT/Neck Normocephalic. Eyes are not open and show prominent epicanthal folds. Ears appear low set but are otherwise normal. Nose shows a depressed nasal bridge. Pharynx normal. Neck supple; no masses or bruits; thyroid normal. Chest/Lung Chest wall normal. Diaphragm and chest move equally and symmetrically with respiration. No abnormality on percussion or auscultation. Heart/Cardiovascular S1 and S2 normal. No murmurs, rubs, gallops, or extra sounds. Central and peripheral pulses normal. No jugular venous distention. Blood pressure equal in both arms. Abdomen Bowel sounds normal; no bruits. No masses or tenderness. Liver and spleen not palpable. No hernias. Extremities/Spine Extremities symmetric without cyanosis or clubbing. Single palmar crease on both hands. Peripheral pulses normal. No joint deformity or warmth; full range of motion. Spine examination normal. Neuro/Psych Alert; neurologic findings normal. What is the suspected diagnosis, and what are the next steps in management? 290 II—CCS CASES BY CHIEF COMPLAINT Case #119: Down Syndrome; Duodenal Atresia Keys to Diagnosis n n n In neonates, symptoms include vomiting from duodenal atresia, absence of stools from Hirschsprung disease, heart murmur from ventricular or atrial septal defect, or abnormal facies. In older children, the presentation may be related to abnormalities in hearing, vision, developmental delay, infections, delays in cognitive abilities, and behavioral changes. On exam, look for abnormalities on HEENT exam: epicanthal folds; nystagmus; flat nasal bridge; tongue protrusion; and small, low-set ears. On heart exam, there may be a murmur from congenital heart defect. Diagnosis is based on cytogenetic evaluation showing a trisomy 21 karyotype. For duodenal atresia, plain abdominal radiograph shows a typical “double-bubble” sign. Abdominal ultrasound or upper GI series can be considered if the diagnosis is in doubt or to exclude other causes, such as a midgut volvulus. For a heart murmur, order echocardiography. Order CBC to look for leukemia. Management n n n Treatment for duodenal atresia is surgery. Nasogastric tube to remove any contents and IV fluids. A thyroid screen should be performed at birth as well as evaluating for additional abnormalities. Consult genetics, pediatric cardiology or pediatric endocrinology as indicated.

In the past 2 days, she has noticed swelling of the scrotum and lower extremities as well. The patient had an upper respiratory tract infection 2 weeks ago that resolved on its own. He has never had these symptoms before. No one else in the household has reported similar symptoms. •Past medical history includes being born by normal vaginal delivery without complications. •Family history, developmental history, and review of systems are unremarkable. INITIAL MANAGEMENT Exam •General, Skin, Lymph nodes, HEENT, Chest, Heart, Abdomen, Genitalia, Rectal, Extremities, Neuro Initial Results: Advance to results of physical exam Physical Exam Results (Pertinent Findings) General Well developed, well nourished; in no apparent distress. HEENT/Neck Normocephalic. Vision normal. Eyes show periorbital swelling. Hearing normal. Ears, including pinnae, external auditory canals, and tympanic membranes, normal. Nose normal. Mouth shows perioral swelling. Pharynx normal. Neck supple; no masses or bruits; thyroid normal. Chest/Lung Chest wall normal. Diaphragm and chest move equally and symmetrically with respiration. No abnormality on percussion or auscultation. Heart/Cardiovascular S1 and S2 normal. No murmurs, rubs, gallops, or extra sounds. Central and peripheral pulses normal. No jugular venous distention. Blood pressure equal in both arms. Abdomen Bowel sounds normal; no bruits. No masses or tenderness. Liver and spleen not palpable. No hernias. Genitalia Normal circumcised penis; scrotal swelling present; testes without masses. No inguinal hernia. Extremities/Spine Extremities symmetric without deformity, cyanosis, or clubbing. 2+ pitting edema. Peripheral pulses normal. No joint deformity or warmth; full range of motion. Spine examination normal. Neuro/Psych Alert; neurologic findings normal. What is the suspected diagnosis, and what are the next steps in management? 292 II—CCS CASES BY CHIEF COMPLAINT Case #120: Nephrotic Syndrome; Minimal Change Disease Keys to Diagnosis n n n Edema is the most common presentation, with swelling seen in the periorbital, perioral, scrotal, labial, and abdominal areas and in the lower legs. Other symptoms include anorexia, fatigue, irritability, abdominal discomfort, and diarrhea. A history of respiratory tract infection or allergies is frequent. On exam, look for pitting edema and swelling in the face, abdomen, or genitals. Diagnosis is established by urinalysis and urine protein quantitation with low albumin and hyperlipidemia. Renal biopsy is generally not necessary unless initial treatment fails. ­Look for abnormal electrolytes on BMP. Management n n n Prednisone is the mainstay of therapy, generally for 6-8 weeks. Edema is treated with low-sodium diet. Medication, such as hydrochlorothiazide (monitor for hypokalemia) may be used in severe cases. Newly diagnosed patients may be admitted for diagnostic and educational ­purposes. ­Immediate attention is required for severe scrotal edema, dehydration, peritonitis, or ­respiratory compromise caused by pulmonary edema.
