Cholecystectomy is the most common surgical procedure in the elderly. Published reports on this operation suffer from small sample sizes, crude analyses, erroneous conclusions, and unsupported recommendations. The authors reviewed all first operations for cholelithiasis at the North Carolina Memorial Hospital from 1973 to 1982 to assess factors associated(More)
BACKGROUND Case-control studies have demonstrated that screening by sigmoidoscopy is effective in reducing mortality from colorectal cancer. If nurses performed screening examinations, more patients could be screened and, at current income levels, at a lower cost. METHODS Two registered nurses and two licensed practical nurses learned to perform(More)
In 1991, only symptomatic gallstones should be treated. The treatment of choice for all gallstones continues to be surgical removal. Except for stones in the common bile duct, which are amenable to removal by endoscopic papillotomy, nonsurgical treatment of gallstones should be investigated further before it can have widespread applicability. The major(More)
Restrictive cardiomyopathy produced by primary cardiac amyloidosis may have a clinical syndrome identical to noncalcific constrictive pericarditis. We report two patients with amyloidosis and restrictive physiology who had enlarged papillary muscles shown on left ventricular angiocardiogram. Rapid volume expansion with normal saline failed to produce(More)
We reviewed all first operations for cholelithiasis at the North Carolina Memorial Hospital from 1973 to 1982 to assess factors associated with postoperative morbidity in diabetics after biliary tract surgery. Diabetics (n = 126) had more frequent postoperative complications (24.6% vs. 12.5%, p less than 0.001) and higher mortality (7.9% vs. 3.0%, p = 0.02)(More)
Using classical conditioning procedures, the cardiac conditioned response (CCR) was established by pairing one of two tones with the delivery of a peripheral electric shock in Rhesus monkeys. The other tone had no terminal consequence. Such a procedure results in an anticipatory ‘anxiety’ or ‘fear’ response to the impending shock signalled by the reinforced(More)
