[Antimicrobial prophylaxis in urethrocystoscopy. Comparative study].

Instrumentation of lower urinary tract is a predisposing factor for the development of urinary infection. Incidence of infective complications following urethrocystoscopy has been evaluated in a multicenter, prospective, comparative and randomized study in 2,284 patients, who had a previous negative urine culture. Patients were randomized into two groups: one to be used as control and the other one to received antimicrobial prophylaxis prior to instrumentation (ceftriazone, 1 gr intramuscular). Clinical and microbiological responses were evaluated at 48-72 hours and 4 weeks after cystoscopy. Symptomatic bacteriuria was observed in 10.2% of patients in the control group and in 2.5% in the prophylaxis group (p < 0.000); asymptomatic bacteriuria in 3.02% and 1.52% (p > 0.05) and irritative syndrome with sterile urine in 2.93% and 2.60% (p > 0.05), respectively. Thus, the use of prophylaxis reduced the incidence of infective complications in these patients.

[Antibiotic therapy of infected cerebrospinal fluid in hydrocephalus treated by a shunt].

Nine hydrocephalic shunted children with infected cerebrospinal fluid (CSF) were treated. Ages ranged from 0 to 10 years. Diagnosis was made through clinical symptoms, CSF examination, echographic and computed tomography (CT). The microorganism which was seen more frequently, was S. epidermidis. This germ was more often found in young children. Treatment of these patients consisted of a systematic change of the shunt which was externally diverted, implantation of a CSF Ommaya reservoir in the lateral ventricle, and intraventricular and systemic administration of antibiotic, were made. Using this protocol CSF sterilization was obtained in all cases, after 5 to 12 days of treatment. CSF shunt infected with S. epidermidis can be effectively cleaned with daily intra-shunt vancomycin, and shunt infected with gram-negative are also cleaned with daily intra-shunt gentamycin.
