Pediatric endocrinology and emergency medicine

Pediatric Diabetic Ketoacidosis

Pediatric diabetic ketoacidosis requires rapid confirmation of hyperglycemia, ketonemia, and acidosis; protocolized isotonic fluid resuscitation, potassium replacement, and delayed low-dose intravenous insulin; and intensive neurologic surveillance for cerebral edema while treating the precipitant and preventing recurrence.[21]
Read guide

Neonatology

Neonatal Sepsis

Neonatal sepsis requires immediate culture-directed evaluation and empiric treatment when illness is plausible, while structured early-onset risk assessment, serial examination, and timely culture review prevent avoidable antibiotic exposure in uninfected infants.
Read guide

Pediatrics

Child Abuse and Neglect

Child abuse and neglect require prompt recognition, meticulous medical assessment, protection-focused communication, and reporting under applicable law. Clinicians should distinguish medical mimics from concerning injury patterns while avoiding delay in safeguarding, multidisciplinary evaluation, and referral for ongoing physical and mental health needs.
Read guide

Neonatology

Neonatal Respiratory Distress Syndrome

Neonatal respiratory distress syndrome is surfactant-deficiency respiratory failure in premature infants. Early recognition, noninvasive respiratory support, selective surfactant delivery, and avoidance of injurious ventilation are central decisions while infection, transient tachypnea, and air-leak disorders remain in the differential.
Read guide

Neonatology and Pediatric Infectious Diseases

Neonatal Meningitis

Neonatal meningitis requires prompt cerebrospinal fluid evaluation and hospital-based empiric antimicrobial therapy because clinical findings are nonspecific, culture sensitivity falls after antibiotics, and delayed recognition risks death and neurodevelopmental disability.
Read guide

Pediatrics

Acute Otitis Media

Acute otitis media requires confirmation of middle-ear effusion with compatible tympanic-membrane inflammation, not symptoms or erythema alone. Management hinges on analgesia, selective antibiotic use, reassessment of nonresponse, and recognition of uncommon suppurative or intracranial complications.
Read guide

Pediatrics

Kawasaki Disease

Kawasaki disease requires prompt clinical recognition and coronary surveillance because no confirmatory test exists, incomplete presentations remain at risk for coronary aneurysm, and treatment should not be deferred for a negative early echocardiogram or rigid completion of fever-duration criteria.
Read guide

Neonatology

Neonatal Hypoglycemia

Neonatal hypoglycemia requires risk-based screening, time-sensitive operational thresholds, prompt feeding or dextrose therapy, and escalation for symptomatic, severe, recurrent, or persistent low glucose values while recognizing that universally validated neuroprotective thresholds remain unavailable.
Read guide

Pediatric Infectious Disease

Tuberculosis in Children

A practical approach to pediatric tuberculosis centers on separating exposure, infection, and disease; obtaining microbiologic confirmation whenever feasible; identifying CNS and disseminated disease urgently; and matching treatment to disease severity, susceptibility, age, and the likely source-case resistance pattern.
Read guide

Pediatrics

Febrile Seizure

Classify the event promptly, treat ongoing convulsions as status at 5 minutes, and direct testing toward meningitis or another cause of fever. A neurologically normal child with a simple febrile seizure generally needs fever-focused evaluation rather than EEG, imaging, or antiseizure prophylaxis.
Read guide

Pediatrics

Croup

Manage croup by recognizing impending upper-airway failure, separating viral disease from epiglottitis, bacterial tracheitis, and foreign body, then using corticosteroids for symptomatic disease and nebulized epinephrine for clinically important obstruction with repeated bedside reassessment.
Read guide

Pediatrics

Infantile Hypertrophic Pyloric Stenosis

In an infant with progressive nonbilious projectile emesis, rapidly distinguish pyloric obstruction from bilious or systemic emergencies, confirm suspected hypertrophic pyloric stenosis with ultrasound when needed, correct dehydration and metabolic alkalosis before anesthesia, then proceed to pyloromyotomy.
Read guide

Pediatrics

Pediatric Asthma

Confirm variable airflow limitation when feasible, treat exacerbations promptly with bronchodilation and early corticosteroids, and adjust long-term therapy according to current control, exacerbation risk, adherence, inhaler technique, and age-specific treatment options.
Read guide

Pediatric Endocrinology

Congenital Hypothyroidism

Manage an abnormal newborn screen as a time-critical thyroid hormone deficiency: confirm with serum testing, begin levothyroxine promptly, monitor free T4 and TSH intensively, and use thyroid imaging to clarify permanence without delaying treatment.
Read guide

Pediatrics

Severe Acute Malnutrition

Recognize severe acute malnutrition by anthropometry or nutritional edema, distinguish marasmus from kwashiorkor, triage complications requiring inpatient stabilization, and transition feeding deliberately to avoid metabolic and fluid-related deterioration.
Read guide

Neonatology

Neonatal Jaundice

Manage neonatal jaundice with age-specific bilirubin assessment, prompt identification of hemolysis and other high-risk patterns, guideline-based phototherapy, and urgent escalation for bilirubin encephalopathy or exchange-level hyperbilirubinemia.
Read guide

Pediatrics

Pediatric Pneumonia

Manage pediatric pneumonia by first identifying hypoxemia, respiratory distress, sepsis, and pleural complications; use selective imaging and microbiology; avoid biomarkers as stand-alone bacterial tests; and reassess nonresponse early for complications, resistant pathogens, or an alternative diagnosis.
Read guide

Pediatrics

Failure to Thrive

Failure to thrive is a growth pattern requiring confirmation on serial, correctly plotted measurements, structured feeding assessment, and targeted testing for medical, developmental, and social contributors. Most children can begin outpatient nutritional and behavioral intervention; acute illness, severe undernutrition, or tube-feeding need changes disposition.
Read guide

Pediatric endocrinology

Androgen Insensitivity Syndrome

Diagnose androgen insensitivity syndrome by confirming a 46,XY DSD, excluding impaired testosterone synthesis, and identifying androgen receptor dysfunction. Management requires phenotype-specific counseling, coordinated DSD expertise, individualized gonadal decision-making, hormone planning, and lifelong attention to bone, sexual, reproductive, and psychosocial health.
Read guide

Pediatric Orthopedics

Legg-Calvé-Perthes Disease

Legg-Calvé-Perthes disease requires early recognition of femoral-head ischemia, radiographic staging, and age- and severity-based containment decisions to preserve hip congruence. Management hinges on range of motion, lateral pillar involvement, extrusion, and timely pediatric orthopedic referral.
Read guide

Sports Medicine and Pediatrics

Osgood-Schlatter Disease

Diagnose Osgood-Schlatter disease clinically in adolescents with load-provoked tibial tubercle pain, while using radiographs selectively for unilateral, severe, persistent, or traumatic presentations that may indicate another proximal tibial lesion or avulsion injury.
Read guide

Developmental-Behavioral Pediatrics

Down Syndrome

Clinical care in Down syndrome requires structured surveillance for congenital heart disease and evolving multisystem complications, plus a deliberate adult-life transition plan that recognizes the high risk of Alzheimer disease and changing care needs.
Read guide

Developmental-Behavioral Pediatrics

Fetal Alcohol Syndrome

Fetal alcohol syndrome is the severe phenotypic end of prenatal alcohol exposure, recognized by characteristic facial dysmorphology, growth impairment, and central nervous system dysfunction. Identification should trigger multidisciplinary neurodevelopmental assessment and needs-based intervention rather than reliance on facial findings alone.
Read guide

Pediatric Gastroenterology and Pediatric Surgery

Hirschsprung Disease

Suspect Hirschsprung disease in neonatal distal bowel obstruction or refractory constipation with delayed meconium. Stabilize enterocolitis and obstruction first, establish aganglionosis by rectal pathology, define disease extent for pull-through planning, and systematically evaluate postoperative obstruction, soiling, and recurrent enterocolitis.
Read guide

Pediatrics

Sudden Infant Death Syndrome

SIDS is a postmortem diagnosis of exclusion. Prevention hinges on repeated counseling for a supine, uncluttered infant sleep environment, while every sudden unexpected infant death requires coordinated history review, scene investigation, complete autopsy, and ancillary testing to distinguish unexplained death from suffocation, disease, trauma, or neglect.
Read guide

Pediatrics and Infectious Disease

Hand, Foot, and Mouth Disease

Hand, foot, and mouth disease is usually diagnosed clinically and managed with hydration-focused supportive care. The key physician task is to recognize dehydration, neurologic or cardiopulmonary complications, and mimics requiring lesion PCR, cerebrospinal fluid evaluation, or alternate treatment.
Read guide

Developmental-Behavioral Pediatrics and Psychiatry

Attention-Deficit/Hyperactivity Disorder

Diagnose ADHD through DSM-5 criteria, cross-setting impairment, collateral history, and active exclusion of competing conditions. Match treatment intensity to age, impairment, comorbidity, cardiovascular risk, adverse effects, and patient preference; monitor functional response rather than symptom scores alone.
Read guide

Developmental-Behavioral Pediatrics

Autism Spectrum Disorder

Use developmental surveillance and validated screening to trigger a comprehensive diagnostic assessment, then initiate individualized behavioral, communication, educational, and co-occurring-condition management without waiting for a single test to define care.
Read guide

Child and Adolescent Psychiatry

Conduct Disorder

Conduct disorder requires behavior-specific assessment, careful differentiation from trauma, mood, neurodevelopmental, and substance-related conditions, and treatment that targets family, school, peer, and comorbid drivers rather than aggression alone.
Read guide

Child and Adolescent Psychiatry

Oppositional Defiant Disorder

Evaluate persistent defiance by confirming clinically significant impairment, separating oppositional behavior from conduct disorder and chronic irritability syndromes, identifying ADHD and other comorbidity, and initiating parent-focused behavioral treatment while treating coexisting disorders with diagnosis-specific care.
Read guide

Pediatric Hematology, Immunology, and Transplantation

Wiskott-Aldrich Syndrome

Suspect Wiskott-Aldrich syndrome in boys with persistent microthrombocytopenia, eczema, infections, autoimmunity, or lymphoid malignancy; confirm the WAS variant and expedite curative therapy planning, because hematopoietic transplantation outcomes decline with older age and severe pretransplant infection.
Read guide

Pediatrics

Bronchiolitis Oxygen and Admission Criteria

Use respiratory effort, feeding safety, apnea history, risk factors, and persistent hypoxemia—not an isolated pulse-oximeter value—to determine disposition. For typical U.S. practice, initiate oxygen below 90%, reassess clinically after stabilization, and discontinue continuous monitoring once oxygen needs and work of breathing improve.
Read guide

Pediatric Emergency Medicine

Pediatric Croup Treatment

Treat croup severity at the bedside: give single-dose dexamethasone for children seeking care, add nebulized epinephrine for stridor at rest or increased work of breathing, observe after epinephrine, and escalate promptly when hypoxemia, exhaustion, or poor response suggests impending airway failure.
Read guide

Pediatric Emergency Medicine and Critical Care

Pediatric Asthma Escalation

Escalate pediatric asthma care according to response to initial bronchodilation, oxygenation, work of breathing, and trajectory. This guide defines practical triggers for intravenous magnesium, continuous albuterol, noninvasive support, PICU transfer, intubation planning, and avoidance of low-value rescue therapies.
Read guide

Pediatrics

Pediatric UTI Testing

Diagnose pediatric urinary tract infection by pairing an appropriately collected urine culture with urinalysis evidence of inflammation, while using collection method, age, illness severity, and imaging triggers to avoid contamination-driven treatment and identify obstructive or recurrent disease.
Read guide

Neonatology

Neonatal Jaundice Phototherapy Thresholds

For infants born at 35 weeks’ gestation or later, initiate phototherapy using the 2022 AAP hour-specific total serum bilirubin threshold matched to gestational age and bilirubin neurotoxicity risk factors, then use the bilirubin-to-threshold difference to determine discharge follow-up and escalation.
Read guide

Pediatric Emergency Medicine

Read guide

Pediatrics

Pediatric Dehydration Rehydration

Select oral rehydration for most children with mild-to-moderate dehydration, use nasogastric ORS when drinking fails, and reserve isotonic intravenous fluid for shock, deterioration, altered mental status, ileus, or failed enteral therapy.
Read guide

Neonatology, Pediatric Cardiology, Adult Congenital Heart Disease

Patent Ductus Arteriosus

Manage PDA by separating preterm ductal patency from a clinically consequential shunt and from persistent congenital PDA in older patients. Echocardiography establishes anatomy and physiology; treatment is reserved for hemodynamic consequences, with transcatheter closure increasingly favored when definitive intervention is required.
Read guide

Pediatric Cardiology and Adult Congenital Heart Disease

Transposition of the Great Arteries

D-transposition requires rapid confirmation of anatomy, maintenance of effective intracardiac mixing, and neonatal anatomic repair; lifelong surveillance after arterial switch focuses on coronary obstruction, neo-aortic disease, ventricular function, and pulmonary arterial lesions.
Read guide

Dermatology and Pediatrics

Tinea Capitis

Confirm suspected scalp dermatophyte infection with hair and scale microscopy or culture when feasible, begin systemic therapy because topical agents do not reach the follicular infection, identify inflammatory kerion promptly to limit permanent alopecia, and interrupt household transmission with contact assessment and sporicidal shampoo.
Read guide

Pediatric Endocrinology

Delayed Puberty

Evaluate delayed puberty by separating constitutional and functional delay from central hypogonadism and primary gonadal failure. Growth trajectory, bone age, pubertal examination, LH/FSH, and sex steroids direct targeted evaluation, timed observation, puberty induction, and long-term replacement planning.
Read guide

Pediatric Endocrinology

Precocious Puberty

Evaluate early pubertal signs by separating transient or isolated variants from progressive hypothalamic-pituitary-gonadal activation and gonadotropin-independent disease. Age, tempo, growth, bone maturation, gonadotropin testing, and targeted imaging determine who needs observation, etiologic investigation, or GnRH-agonist suppression.
Read guide

Pediatrics

Lymphadenopathy

Use nodal distribution, trajectory, systemic findings, and targeted testing to separate self-limited reactive disease from bacterial infection, granulomatous disease, autoimmune disease, and malignancy; escalate persistent, high-risk, or unexplained presentations to tissue diagnosis without relying on nondiagnostic needle sampling.
