Role of ultraosonography in grading of penile fractures.

Introduction: Penile fracture is an uncommon and less reported condition. Early diagnosis with corrective measures is the order of the day.

Aim: To perform ultrasonography of penis and to understand its role in making correct diagnosis of fractures.

Sarcina organisms in the gastrointestinal tract: a clinicopathologic and molecular study.

Sarcina organisms were first observed in and recorded from the stomach contents of a patient suffering from vomiting by John Goodsir in 1842. Since that time, their fine structure, phylogenetic classification, and biochemical characteristics have been described. Although numerous cases of fatal disease have been attributed to this organism in the veterinary literature, only a few human cases have been documented.

Mucosal prolapse syndrome presenting as rectal polyposis.

Mucosal prolapse syndrome comprises a variety of clinical and histopathological entities, with mucosal prolapse as the underlying pathogenic mechanism. Due to variable clinical, endoscopic and histopathological presentation and rareness of symptomatic mucosal prolapse, misdiagnosis resulting in delayed or inappropriate treatment is frequent. This report describes a patient initially diagnosed with a colorectal polyposis syndrome consisting of multiple rectal hyperplastic and adenomatous polyps.

Upper gastrointestinal tract injury in patients receiving kayexalate (sodium polystyrene sulfonate) in sorbitol: clinical, endoscopic, and histopathologic findings.

Kayexalate (sodium polystyrene sulfonate) in sorbitol has been demonstrated to cause colonic necrosis in a subset of uremic patients who are administered the cation exchange resin for treatment of hyperkalemia. Upper gastrointestinal damage associated with Kayexalate in sorbitol is reported far less frequently, and the clinicopathologic spectrum of disease in cases with upper gastrointestinal damage has not been investigated previously. The authors studied the clinical, endoscopic, and histologic features of 11 patients with Kayexalate crystals in biopsies from the esophagus (n = 7), stomach (n = 6), and duodenum (n = 2).
