Prognostic factors for survival after pancreaticoduodenectomy for malignant disease.

Forty patients underwent pancreaticoduodenectomy for malignant disease in a 25-year review of 6 Portland-area hospitals. After resection, 10 patients survived for greater than 5 years. Characteristics of survivors included a short prodrome of symptoms, minimal weight loss, tumor in the periampullary region, and female sex.

Problems in diagnosis and management of desmoid tumors.

Thirty-two primary desmoid tumors occurred in 29 patients. The median patient age was 32 years, and 55% of the patients were females. An antecedent history of trauma at the tumor site was elicited from 28% of patients.

The effect of prolonged aspirin therapy on experimental balloon-catheter arterial wall injury.

Indications for aspirin following percutaneous transluminal angioplasty are not well defined. Although aspirin's early antithrombotic effect is believed to be beneficial, the long-term influence of aspirin on myointimal proliferative response following balloon-catheter angioplasty is still being investigated. This study quantitates arterial wall thickening, including intimal hyperplasia, at 4 months following balloon-catheter aortic injury in New Zealand white rabbits (n = 12), comparing aspirin treatment (30 mg/kg) with controls.

Repeat parathyroid operation associated with renal disease.

One hundred ten patients who had undergone operation for secondary and tertiary hyperparathyroidism have been described. Ninety patients had secondary disease and 20 patients had tertiary disease after renal transplantation. From these two groups, 18 patients had repeat operations for control of recurrent or persistent disease.
