Eosinophilic enteritis with ascites in a patient with overlap syndrome.

Gastrointestinal involvement is frequent in patients with systemic lupus erythematosus (SLE). Eosinophilic gastroenteritis, however, has only rarely been described in rheumatological conditions, despite its reported connection to autoimmune diseases, such as hypereosinophilic syndrome, vasculitides, and systemic mastoidosis. It presents typically with abdominal pain and diarrhea and is only exceptionally associated with ascites. Diagnosis can be problematic, as several other clinical conditions (malignancies, infection/tuberculosis, and inflammatory bowel diseases) have to be ruled out. It is basically a nonsurgical disease, with excellent recovery on conservative treatment. We report the rare case of a young woman with overlap syndrome who presented with abdominal pain and ascites. The diagnosis of eosinophilic enteritis was made based on clinical, radiological, and laboratory criteria. The patient was treated with corticosteroids with excellent response.

Congenital bilateral pharyngoceles: an unusual case of upper dysphagia.

Pharyngocele is infrequently reported in the literature and is rarely considered in the differential diagnosis of upper dysphagia. We describe the case of a healthy young man, without any history of activities that would result in elevated intrapharyngeal pressure, with difficulty swallowing since childhood. Bilateral pharyngoceles were diagnosed after barium swallow and carbonated-beverage ingestion. We discuss the possibility that our patient's pharyngoceles may be congenital in origin from an internal branchial sinus anomaly.

Secondary aortoduodenal fistula with a fatal outcome: report of six cases.

Secondary aortoenteric fistulas (AEFs) are a well-known but uncommon cause of gastrointestinal hemorrhage. They usually occur secondary to reconstructive surgery of an abdominal aneurysm. We report six cases of secondary aortoduodenal fistulas, involving patients who, despite presenting with classic "herald bleeding," died as a result of delayed operative intervention. We also discuss the pathogenesis, clinical presentation, and diagnosis of AEFs, emphasizing the value of clinical suspicion and negative endoscopy in establishing the diagnosis and the need for early operative intervention.

Endoscopic sphincterotomy in adult hemophiliac patients with choledocholithiasis.

BACKGROUND: The aim of this study was to investigate the risk of bleeding in adult hemophiliac patients undergoing endoscopic sphincterotomy for choledocholithiasis. METHODS: From 1983 to 2002, 7 patients with hemophilia A and two with hemophilia B were referred for endoscopic sphincterotomy and extraction of bile duct stones. The degree of hemophilia was mild in 4 patients, moderate in 3, and severe in two. Pre-admission levels of blood clotting factors ranged from less than 1% to 18%. Levels of the deficient factors were monitored carefully before and after sphincterotomy, and the relevant factor was replaced to achieve 100% activity before and for 24 hours after endoscopic sphincterotomy. OBSERVATIONS: Seven patients had factor replacement every 8 hours, and two received continuous infusions. No patient developed bleeding after sphincterotomy. At discharge, 48 hours after the procedure, patients who had received continuous infusions had a factor level of greater than 90%; those who had received intermittent replacement had levels of greater than 50%. After discharge, the patients were treated with regular infusion of the deficient factor for 15 days. CONCLUSIONS: With adequate preoperative and post-procedure monitoring of clotting factors, meticulous attention to hemostasis during sphincterotomy, careful post-procedure monitoring, and timely replacement therapy, patients with hemophilia can undergo endoscopic sphincterotomy without bleeding complications.
