Abstract: One hundred forty-four patients were prospectively followed through our Asplenic Registry for the development of late septic complications following splenectomy for trauma. There were 114 males and 30 females with a mean age of 28.6 years. The total time of followup was 8,810 patient months with a mean followup of 61 months (range, 12-144 months). Indications for splenectomy were blunt trauma, 111 patients; penetrating trauma, six patients; and intra-operative injury, 27 patients. During the followup to date, 15 late major septic complications requiring hospitalization have occurred in 13 patients (9%). Fulminant pneumococcal sepsis resulted in the death of a 27-year-old male, 3 years after splenectomy. Septicemia occurred in four patients, pneumonia in five, abscess in two, infection of a prosthetic heart valve in one, meningitis in one, and fever of unknown origin in one. All but two of these infections were due to encapsulated organisms. Minor septic complications occurred in 44 patients (30%), and consisted of infections which required outpatient medical care. Major late septic complications occurred more frequently following incidental splenectomy than following splenectomy for blunt or penetrating trauma (18.5% and 5.9% respectively; p less than 0.05). The mortality from major septic complications in this series (7%) is lower than previously reported by other investigators (30-80%). Our data suggest that adults undergoing splenectomy for trauma are at an increased risk of developing late major septic complications. This risk is significant enough to warrant attempts at splenic salvage, especially when injury is incidental to an elective operative procedure.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract: The purpose of the study was to compare the renal effects of low doses of exogenous dopamine to assess the responsiveness of renal dopaminergic receptors in normotensive and hypertensive subjects. Eight hypertensive patients and seven normotensive volunteer subjects were studied. Inulin and para-aminohippuric (PAH) clearances, natriuresis, and fractional excretion of sodium increased significantly after intravenous dosing with dopamine (2 micrograms/min/kg) in both groups. These increases were significantly higher in hypertensive than in normotensive subjects: 31.8% +/- 3.7% vs. 16.2% +/- 1.2% for inulin clearance (P less than 0.01), 83.3% +/- 10.5% vs. 41.1% +/- 3.4% for PAH clearance (P less than 0.01), and 331% +/- 38% vs. 216% +/- 26% for natriuresis (P less than 0.01). These findings suggest hyperresponsiveness to dopamine during hypertension. This enhanced response to exogenous dopamine can be considered as a further argument favoring the existence of a deficit in dopaminergic activity during hypertension. Dopamine also induced a significant reduction in blood pressure and increased heart rate in hypertensive subjects but no significant change in blood pressure and heart rate occurred in normotensive subjects.

Abstract: This double-blind, randomized study evaluated the effect of nifedipine on restenosis after coronary angioplasty. Two hundred forty-one patients with dilation of 271 coronary sites were randomized at the time of hospital discharge to receive nifedipine, 10 mg (123 patients), or placebo (118 patients) four times daily for 6 months. No patient was known to have coronary artery spasm. The mean duration of therapy was 4.4 +/- 2 (mean +/- SD) months for nifedipine and 4.3 +/- 2 months for placebo. A restudy angiogram was available in 100 patients (81%) in the nifedipine group and 98 patients (83%) in the placebo group. A recurrent coronary stenosis was noted in 28% of patients in the nifedipine group and in 29.5% of those in the placebo group (p = NS). The mean diameter stenosis was 36.4 +/- 23% for the nifedipine group and 36.7 +/- 23% for the placebo group (p = NS). By pill count, 78% of patients receiving nifedipine and 82% of those receiving placebo complied with the study drug regimen. Coronary stenosis recurred in 33% of patients in the placebo group and in 29% of patients in the nifedipine group who complied with the regimen and had angiograms (p = NS). In conclusion, the study did not demonstrate a significant beneficial effect of nifedipine on the incidence of recurrent stenosis after successful percutaneous transluminal coronary angioplasty.
