Intestinal perforation in ascariasis--case reports.

Two cases of intestinal perforation in association with ascariasis are described. In both cases adult ascarids were found either in the gut or lying free in the peritoneal cavity. Neither patient had typhoid fever, one had Hodgkin's lymphoma.

Spinal cord compression in thalassaemia.

Two cases of spinal cord compression resulting from extramedullary haemopoiesis in patients with thalassaemia of intermediate clinical severity are reported. The association between mild thalassaemia with long survival and the risk of spinal cord compression from extramedullary haemopoietic deposits is emphasised.

Xanthogranulomatous pyelonephritis: a report of 2 cases.

Two cases of xanthogranulomatous pyelonephritis are reported in Negroes. The clinical findings are similar to those in previously reported cases. In 1 case nephrolithotomy was followed by the development of a perinephric abcess 8 months later.

Hyperinfection syndrome with Strongyloides stercoralis in malignant lymphoma.

Hyperinfection with Strongyloides stercoralis occurred in three patients with malignant lymphoma. The probable cause in each case was alteration of the immune responses either as a result of the malignant lymphoma or by the treatment given. Though thiabendazole (Mintezol) has produced reasonable results in the treatment of the hyperinfection syndrome, preliminary data suggest that the new broad-spectrum anthelmintic levamisole (Ketrax) is more effective.
