Randomized Controlled Trial Clinical Trial
Long-term efficacy of intranasal mupirocin ointment. A prospective cohort study of Staphylococcus aureus carriage.
We investigated the long-term effect of a single 5-day application of intranasal mupirocin calcium ointment on Staphylococcus aureus nasal and hand colonization. The subjects were 68 healthy volunteers who were health care workers with stable S aureus nasal carriage and who had participated in a randomized, double-blind placebo-controlled clinical trial of intranasal mupirocin ointment. ⋯ A single brief treatment course of intranasal mupirocin was effective in reducing nasal S aureus carriage for up to 1 year. When S aureus was recovered after nasal decolonization, the new isolate was as likely to represent colonization with a new strain as reisolation of the original strain. Staphylococcus aureus hand carriage was significantly decreased 6 months after therapy, further implicating the nares as the primary reservoir site for hand carriage.

Randomized Controlled Trial Comparative Study Clinical Trial
Empiric monotherapy versus combination therapy of nosocomial pneumonia in trauma patients.
Combination therapy for nosocomial pneumonia with a beta-lactam and aminoglycoside is widely accepted because of synergy and reduction of resistant bacteria. This prospective study of 109 trauma patients (94 blunt, 15 penetrating) with nosocomial pneumonia was performed in consecutive phases. In phase 1, patients were randomized to an anti-pseudomonal third-generation cephalosporin--cefoperazone or ceftazidime. ⋯ We conclude that monotherapy had a higher cure rate than combination therapy for empiric therapy of pneumonia in our trauma patients. Combination therapy failed because of superinfection (primarily MRSA). Emergence of MRSA may be from host overgrowth or plasmid-mediated induction of resistance, possibly caused by gentamicin.

Randomized Controlled Trial Comparative Study Clinical TrialA randomised comparison of single-dose vs. three-day and ten-day therapy with trimethoprim-sulfamethoxazole for acute cystitis in women.
The efficacy of a single-dose (4 tablets) trimethoprim-sulfamethoxazole (TMP-SMX) was compared with that of a 3-day and 10-day treatment with TMP-SMX, 2 tablets twice daily, in 464 female out-patients with symptoms denoting acute, uncomplicated urinary tract infection (UTI). 321 patients (70%) had significant bacteriuria. Treatment effect could be assessed in 279 women. ⋯ The incidence of adverse reactions was significantly greater in patients treated with a 10-day (28%) than in those treated with a single-dose (5%), or 3-day (9%) regimen (p less than 0.01). This study suggests that short treatment regimens for uncomplicated UTI in women are as effective as and cause fewer side-effects than the conventional 10-day chemotherapy.
