Atrial Fibrillation Risk and Urate-Lowering Therapy in Patients with Gout: A Cohort Study Using a Clinical Database.

Individuals of Asian descent are at higher risk for developing hyperuricemia and gout as compared to Western populations. Urate-lowering therapy (ULT) is an effective treatment for hyperuricemia and gout. It was reported that febuxostat, one of the ULTs, raises the risk of atrial fibrillation (AF) in elderly populations.

A fatal masquerade in pneumonia: Ruptured thoracic aortic aneurysm.

We described an 87-year-old man who presented with fever and hemoptysis. Nosocomial pneumonia was initially suspected. However, the patient had worsening hemoptysis despite defervescence.

Acute myocarditis complicated with permanent complete atrioventricular block caused by Escherichia coli bacteremia: A rare case report.

Rationale: Acute myocarditis complicated with complete atrioventricular block (CAVB) is rare in clinical scenario. We report an uncommon case of myocarditis complicated with permanent CAVB caused by Escherichia coli (E coli) bacteremia.

Patient Concerns: A 77-year-old woman presented at the emergency department with chest pain, dizziness, nausea, and cold sweats of 1-day duration.

Terminal ileum gangrene secondary to a type IV paraesophageal hernia.

Type IV paraesophageal hernia (PEH) is very rare, and is characterized by the intrathoracic herniation of the abdominal viscera other than the stomach into the chest. We describe a 78-year-old woman who presented at our emergency department because of epigastric pain that she had experienced over the past 24 h. On the day after admission, her pain became severe and was accompanied by right chest pain and dyspnea.

Myopericarditis and exertional rhabdomyolysis following an influenza A (H3N2) infection.

Background: Acute myopericarditis and exertional rhabdomyolysis, two uncommon but well-described diseases with potentially life-threatening effects, are generally considered as independent clinical entities. However, they may in fact be pathophysiologically related under certain circumstances. This is the first ever report of influenza myopericarditis provoked by exertional rhabdomyolysis to the best of our knowledge.
