A 22 y/o man presents with ascending weakness and absent reflexes 1 week after a diarrheal illness. CSF analysis shows high protein with normal WBC count. Which of the following best describes the underlying pathology?
💡 EXPLANATION:
Guillain-Barré syndrome is a post-infectious autoimmune condition causing demyelination of peripheral nerves. Diagnosis is supported by albuminocytologic dissociation (elevated protein with normal WBC) on CSF analysis.
A 4 y/o boy presents with a 2/6 systolic murmur at the left lower sternal border. The murmur intensity decreases upon standing and increases when lying supine. He is otherwise asymptomatic. What is the most likely diagnosis?

A 9 y/o girl presents with migratory polyarthritis and painless subcutaneous nodules. Which laboratory test provides the essential evidence to confirm the underlying diagnosis?
💡 EXPLANATION:
The clinical presentation suggests acute rheumatic fever. To fulfill the Jones criteria, evidence of a preceding Group A Streptococcal infection is required, typically confirmed by an elevated Anti-streptolysin O (ASO) titer.

A 9-mo infant presents with 10% dehydration, doughy skin, and a high-pitched cry. Labs reveal Na 155 mmol/L and K 2.3 mmol/L. What is the most likely diagnosis?
💡 EXPLANATION:
Doughy skin, high-pitched cry, and Na > 150 mmol/L indicate hypernatremic dehydration. This occurs when water loss exceeds sodium loss, leading to a concentrated extracellular compartment.

A macrosomic neonate born to a diabetic mother is found to have a blood glucose level of 2.2 mmol/L. What is the most appropriate next step in management?
💡 EXPLANATION:
Neonatal hypoglycemia (glucose < 2.6 mmol/L) in infants of diabetic mothers requires immediate intervention to prevent brain injury. Enteral feeding is the appropriate first step for asymptomatic neonates, followed by rechecking.

A 30-week premature infant develops tachypnea and grunting shortly after birth. Chest X-ray reveals bilateral ground-glass opacities and air bronchograms. Which of the following is the most likely diagnosis?
💡 EXPLANATION:
Respiratory distress syndrome (RDS) in premature infants is caused by surfactant deficiency, leading to alveolar collapse. Classic chest X-ray findings include diffuse ground-glass opacities and air bronchograms.

A 4-month-old girl presents to the clinic. Examination reveals a disproportionately large head, dilated scalp veins, and downward deviation of the eyes (sun-setting eyes). What is the most likely diagnosis?
💡 EXPLANATION:
Macrocrania, dilated scalp veins, and sun-setting eyes (downward deviation) are classic clinical signs of hydrocephalus causing increased intracranial pressure (ICP) in infants.

A 10-month-old infant presents after a 3-minute generalized tonic-clonic seizure associated with a fever of 39°C. The child is currently alert and neurologically intact. What is the most appropriate management?
💡 EXPLANATION:
This is a simple febrile seizure (generalized, <15 mins, no recurrence in 24h). Since the infant is neurologically normal, routine EEG, lumbar puncture, or daily antiepileptic prophylaxis are not indicated. Reassurance is the best step.

A 7 y/o boy presents with brief staring spells lasting 10 seconds. He resumes normal activity immediately with no postictal confusion. What is the most likely diagnosis?
💡 EXPLANATION:
Absence seizures present with brief staring spells and no postictal confusion. Typical EEG shows a 3 Hz spike-and-wave pattern. First-line treatment is ethosuximide.

A 6 y/o boy presents with progressive proximal muscle weakness, difficulty rising from the floor (Gowers sign), and calf pseudohypertrophy. Which of the following proteins is most likely defective in this condition?
💡 EXPLANATION:
The child has Duchenne muscular dystrophy, an X-linked recessive disorder caused by a frameshift mutation in the dystrophin gene. The absent dystrophin leads to progressive myonecrosis, proximal weakness, and elevated CK levels.
