ABSTRACT
Angiostrongylus costaricensis is an intestinal nematode, endemic to Central and South America. Affecting mostly children, it causes an eosinophilic gastroenteritis with involvement of the appendix, distal small bowel, and right colon. We report a case of a 41-yr-old man, from a non-endemic area, with the unique presentation of recurrent gastrointestinal bleeding. The diagnosis was made after surgical exploration.

A simple method for percutaneous insertion of nephrostomy tubes is described. In our series of 47 patients there have been no failed attempts at nephrostomy placement, and only one complication, transient septicemia, was noted. Catheter care is described, and use of the nephrostomy tract for various urologic problems is discussed.

Percutaneous drainage has rapidly become the initial procedure of choice in the treatment of most intra-abdominal abscesses. The retroperitoneal location of the urinary tract facilitates a percutaneous approach and has been found to be highly effective, with surgical intervention required in a minority of cases. Noninfected fluid collections, particularly those related to ureteral or renal pelvic injuries, may also be managed nonsurgically using percutaneous techniques, such as nephrostomy and antegrade stenting.

Renal angiomyolipomas are benign tumors which occur commonly in association with tuberous sclerosis or as isolated lesions. Symptomatic angiomyolipomas, particularly those in patients with tuberous sclerosis, should be approached conservatively with the goal of preserving as much normal renal tissue as possible. We report 2 patients in whom selective embolization was used to achieve this goal.

Intravenous digital subtraction angiography (DSA) was used to evaluate 22 patients with Leriche syndrome. The technique successfully demonstrated both the level of obstruction and the reconstitution of arterial flow to the lower extremities. In view of the relative safety of DSA, compared with the axillary approach in standard angiography, the authors believe that it should be the initial procedure for presurgical evaluation of Leriche syndrome.

Hypertension has been observed to occur frequently in children with burns. In a series of children admitted to the St. Agnes Burn Treatment Center, sustained systolic and diastolic hypertension occurred in 31.5%, and 57.4% of the children demonstrated episodic periods of hypertension which were unsustained. The only clinical finding which significantly correlated with the hypertension was the presence of tachycardia, which persisted into the late healing phase of the thermal injury. Hypertension was more prevalent at younger ages. However, there was no other correlation of the development of hypertension with sex, race, or extent of thermal injury. The development of hypertension in itself did not worsen the prognosis for survival in the cases presented in this series. Possible pathogenic mechanisms which result in hypertension (elevated catecholamines, norepinephrine, renin secretion) are discussed.
