Use of prophylactic antibiotic in clean surgical cases--a prospective trial of various regimens.

In a randomised controlled prospective trial, different antibiotic regimens were evaluated as prophylaxis in wound infection following elective surgical procedures. Four hundred and four consecutive cases were divided in four groups. Two groups were allotted two different conventional postoperative antibiotic regimens while the fourth group received short term perioperative antibiotic; group one served as control. A higher frequency of postoperative wound infection was observed in the controls. Results showed reduction in gross infection in only group III where short term perioperative antibiotic was used. Combination of penicillin and streptomycin were not found effective, and low infection rate was observed with Cephamendole used perioperatively.

Renal bicarbonate handling in low birth weight infants during metabolic acidosis.

We studied the fractional excretion of bicarbonate (FE HCO-3) in 10 low birth weight infants aged 1-6 days during metabolic acidosis (base excess greater than or equal to -5 mEq/l) and during subsequent sodium HCO-3 infusion. The mean birth weight was 1,095 g; the mean gestational age was 29 weeks. The ability to decrease urine pH to less than 5.5 and FE HCO-3 to less than 1% during metabolic acidosis was not limited by low gestational age or birth weight. After HCO-3 therapy, all infants corrected their negative base excess, and plasma HCO-3 increased significantly. All infants with blood pH less than or equal to 7.22 or PaCO2 greater than or equal to 50 mm Hg had minimal or absent FE HCO-3. Infants with elevated PaCO2 and mild or absent acidosis also had complete HCO-3 tubular reabsorption. These results suggest that the HCO-3 tubular reabsorption is adequate during metabolic and/or respiratory acidosis in low birth weight infants.

Psychopathological assessment of child-abusing, neglecting, and normal mothers.

The authors attempted to differentiate groups of abusing, neglecting, and normal mothers on the basis of clinically familiar dimensions of psychopathology. Using the Current and Past Psychopathology Scales (CAPPS), two psychiatrists conducted standardized interviews and blindly assessed 60 subjects. Although the current section of the CAPPS failed to discern more psychopathology in the maltreating parents, a multiple discriminant analysis of 18 past summary scales significantly distinguished the three groups and correctly reclassified 63.3 per cent of the mothers. The neglect group obtained high ratings on the Neurotic Childhood scale, whereas abusers showed greater disturbance on Disorganized and Anger-Excitability.

Prospective randomized trial of a metallic intravascular stent in hemodialysis graft maintenance.

PURPOSE: To evaluate percutaneous transluminal angioplasty (PTA) alone versus PTA and flexible self-expanding stent placement for the management of hemodialysis access graft stenoses. MATERIALS AND METHODS: Thirty-seven grafts in 34 patients were evaluated for abnormal intradialytic parameters (n = 27) or occlusion (n = 10). Angiography identified stenoses (mean, 69%; range, 50%-95%) at or within 3 cm of the vein-graft junction (70%) or in the peripheral outflow vein (30%) that had recurred within a 6-month period after previous PTA. They were randomized to PTA alone (n = 20) or PTA with Wallstent (n = 17). Additional lesions were treated by PTA alone, and a mean of 1.4 (range, 1-3) lesions were treated per patient. Significant differences existed in the mean number of previous accesses (1.8 and 0.8 in the PTA and stent groups, respectively) and in the mean number of previous interventions in the current access (1.8 and 2.9, respectively). End points were subsequent radiologic or surgical intervention, transplantation, and death. RESULTS: Technical success was 100% (mean residual stenosis, 12%; range, 0%-30%). The primary patency of 128 days and secondary patency of 431 days were similar for both groups. Secondary patency required a mean of 1.8 and 1.6 additional interventions for the PTA and stent groups, respectively. The adjunctive stent placement increased the cost of the procedure by 90%. CONCLUSION: Despite significant added costs, there was no advantage to stent placement for recurrent peripheral hemodialysis graft stenoses that were already adequately dilated with balloon angioplasty.
