In this episode, we review Osgood–Schlatter disease, a common cause of anterior knee pain in adolescents and young athletes. We discuss the pathophysiology of traction apophysitis at the tibial tubercle caused by repetitive quadriceps contraction during periods of rapid growth. Key clinical features—including localized tibial tubercle pain that worsens with running, jumping, and kneeling—are highlighted along with the typical physical exam findings that help distinguish this condition from intra-articular knee pathology. We also cover the primarily clinical diagnosis, when imaging may be helpful, and evidence-based conservative management such as activity modification, stretching, and physical therapy. The episode concludes with practical clinical pearls to help clinicians quickly recognize this self-limited condition in active adolescents.

In this episode, we review osteoarthritis, the most common degenerative joint disease and a major cause of chronic pain and disability worldwide. We discuss the underlying pathophysiology of cartilage breakdown, osteophyte formation, and low-grade joint inflammation that leads to progressive joint dysfunction. Key clinical features such as activity-related joint pain, brief morning stiffness, crepitus, and characteristic hand findings—including Heberden and Bouchard nodes—are highlighted, along with the role of imaging in confirming the diagnosis. We also cover evidence-based management strategies, including lifestyle modification, exercise therapy, NSAIDs, intra-articular corticosteroid injections, and indications for joint replacement. This episode concludes with practical clinical pearls to help clinicians recognize osteoarthritis and differentiate it from inflammatory arthritis in everyday practice.

In this episode, we review Zenker diverticulum, a posterior pharyngoesophageal outpouching that develops above the upper esophageal sphincter due to cricopharyngeal dysfunction. We break down the anatomy of the Killian triangle, the pathophysiology of increased intraluminal pressure leading to herniation, and the classic presentation of dysphagia, regurgitation of undigested food, and halitosis in older adults. The discussion highlights the diagnostic role of barium swallow imaging and reviews definitive management with endoscopic cricopharyngeal myotomy.

In this episode, we review Mallory–Weiss tears, a common cause of upper gastrointestinal bleeding characterized by a longitudinal mucosal tear at the gastroesophageal junction following forceful vomiting. We break down the pathophysiology of sudden increases in intra-abdominal pressure, key risk factors such as alcohol use and hiatal hernia, and the classic presentation of hematemesis after retching. The discussion highlights stabilization strategies, the diagnostic and therapeutic role of endoscopy, and how to differentiate this condition from more severe esophageal injuries like Boerhaave syndrome.

In this episode, we review esophageal strictures, an abnormal narrowing of the esophageal lumen most commonly caused by chronic GERD. We break down the pathophysiology of inflammation leading to fibrosis and luminal narrowing, along with other important causes including caustic ingestion, radiation, eosinophilic esophagitis, and malignancy. The discussion highlights the classic presentation of progressive dysphagia to solids, appropriate use of barium swallow and endoscopy, and evidence-based management with endoscopic dilation. We also review red flags for malignancy and complications such as perforation.

In this episode, we review diverticular disease, including the progression from diverticulosis to acute diverticulitis. We break down the pathophysiology of mucosal outpouchings in high-pressure zones of the sigmoid colon and how obstruction can lead to inflammation, abscess, perforation, or peritonitis. The discussion highlights classic left lower quadrant pain, the role of CT imaging for diagnosis and staging, and evidence-based management ranging from outpatient antibiotics to percutaneous drainage or surgical intervention. We also address prevention strategies, common complications such as fistula formation, and key clinical pearls to guide decision-making in both uncomplicated and complicated cases.

In this episode, we review acute cholangitis, a life-threatening infection of the biliary tree that occurs in the setting of obstruction—most commonly from choledocholithiasis. We break down the pathophysiology of increased intrabiliary pressure leading to bacterial overgrowth and systemic infection, along with the classic presentation of Charcot triad: fever, jaundice, and right upper quadrant pain. The discussion highlights key laboratory and imaging findings, the urgency of ERCP for biliary decompression, and the role of broad-spectrum IV antibiotics.

In this episode, we review endoscopic retrograde cholangiopancreatography (ERCP), a specialized procedure used to diagnose and treat biliary and pancreatic duct disorders. We break down the relevant anatomy of the ampulla of Vater and sphincter of Oddi, common indications such as choledocholithiasis and acute cholangitis, and key contraindications to consider before proceeding. The discussion walks through procedural steps, highlights complication risks—particularly post-ERCP pancreatitis—and emphasizes thoughtful patient selection.

In this episode, we review Hirschsprung disease, a congenital disorder caused by the absence of enteric ganglion cells in the distal colon, leading to functional obstruction and chronic constipation. We break down the embryologic failure of neural crest cell migration, classic neonatal findings such as delayed passage of meconium and bilious emesis, and the hallmark "squirt sign" on exam. The discussion highlights appropriate diagnostic strategies—including contrast enema and confirmatory rectal biopsy—and the role of surgical management.

In this episode, we review nonalcoholic fatty liver disease (NAFLD), a common and often silent condition driven primarily by insulin resistance and metabolic dysfunction. We break down the distinction between simple steatosis (NAFL) and nonalcoholic steatohepatitis (NASH), highlighting key pathophysiologic differences such as hepatocellular ballooning and fibrosis. The discussion covers risk factors including obesity, type 2 diabetes, and dyslipidemia, along with appropriate diagnostic evaluation and when to consider liver biopsy. We also emphasize lifestyle modification as the cornerstone of treatment and review the potential progression to cirrhosis and hepatocellular carcinoma.
