ABSTRACT
The authors report the case of a 52-year-old man who had stenosis and necrosis of the right colon secondary to acute pancreatitis. The right colon is a very uncommon location for this complication. The site of the stenosis was documented by contrast enema examination and computed tomography. Although conservative management is usually advocated for the initial management of this complication, laparotomy was necessary when the patient's condition failed to improve with conservative therapy. Colonic necrosis was found at laparotomy, and a partial colectomy was carried out, followed later by ileocolic reanastomosis. The authors emphasize the diagnostic and treatment options for this entity.

Pathological and hemodynamic investigations were performed in 5 canadian patients who had been infected by Schistosoma mansoni four months before in Martinique. Mononuclear cell infiltration of portal tracts was disclosed in all 5 patients; it was associated with eosinophilic infiltration in 3, hepatocellular necrosis in 3, granulomas in 2 and fibrosis in 2. Presinusoidal portal hypertension was demonstrated in 4 out of the 5 patients. These observations suggest that histological changes are constant at this stage after infestation by S. mansoni and could be responsible for the early development of portal hypertension which is classically a late feature of the disease.

Sixteen patients with an established diagnosis of oculopharyngeal muscular dystrophy underwent clinical, radiologic and manometric assessment. Secondary pharyngo-oral and pharyngonasal regurgitations are usually associated with this condition and chronic aspiration with consequent bronchorrhea is common. Such patients may present with marked oropharyngeal dysphagia. Cineradiologic findings correlated well with the mamometric results. The pharynx showed very weak contractions of longer duration than those observed in normal subjects. The proximal esophageal sphincter had a normal resting and closing pressure; however, relaxation and coordination of the sphincter were substantially different from those in a control group. Eleven patients underwent cricopharyngeal myotomy. All had notable improvement of their symptoms. Surgery on the sphincter results in a substantial decrease in its resting pressure; pharyngeal contraction remains unaltered.
