Unusual fungal infections following jejunoileal bypass surgery
Abstract:
Deep-seated fungal infections with unusual clinical courses developed in three previously healthy patients following jejunoleal bypass surgery. Pulmonary blastomycosis disseminated and then relapsed despite repeated courses of amphotericin B in a 40-year-old man; chronic progressive pulmonary histoplasmosis developed in a 38-year-old nonsmoking man; and histoplasmosis of mediastinal nodes became symptomatic in a 32-year-old man. Cell-mediated immunity was evaluated in two patients; no defects were found. However, male patients were found to be at a significantly higher risk of infection than female patients (3/32 vs 0/101; P less than .02). A significantly higher percentage of prebypass weight was lost by the infected men than the uninfected men (P less than .05). Accelerated weight loss clearly preceded the onset of the infection in two of the patients. Jejunoileal bypass surgery should be regarded as a risk factor for serious fungal infection, especially in men with accelerated weight loss.

Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
