METHODS A total of 151 women between 18 and 60 years of age undergoing abdominal hysterectomy during general anesthesia participated in a randomized, double-blind, controlled,(More)
An analysis of 23 consecutive cases of brain abscess is reported. The most frequent early symptoms and signs were headache, vomiting, papiledema, focal neurological abnormalities and pyrexia. Roentgenogram of skull, electroencephahologram and ecoencephalogram were abnormal in all cases in which they were obtained. Therapy was based on early diagnosis with(More)
Human reovirus-like particles were found by electron microscopy in the stools of 25% of 71 infants and young children hospitalized with acute gastroenteritis in Mexico between December 1976 and April 1977. The virus was also identified by the electrophoresis patterns of its ribonucleic acid upon disruption of partially purified particles. This technique is(More)
Hemodialysis (HD) patients can develop acute reactions during treatment as well as increased long-term susceptibility to infections and malignancies. Abnormalities in leukocyte adhesion may contribute to these processes. Recently, serum levels of soluble adhesion molecules have been detected in circulating blood of normal subjects and in patients with(More)
BACKGROUND Silicone has been the standard material for indwelling devices to date. Polyurethane II exhibits properties that makes it suitable as a component of long-indwelling vascular access, with the added advantage of low cost. OBJECTIVE To describe the experience of an intravenous therapy team with 206 polyurethane II catheters used as long-indwelling(More)
Pharmacologic data are presented on 39 children treated for osteomyelitis with one of the following antibiotics: methicillin, dicloxacillin, cephaloridine, or cefazolin. The concentrations of drug in pus and bone were correlated with serum concentrations, with the susceptibilities of Staphylococcus aureus strains isolated from the patients, and with the(More)
BACKGROUND This paper describes the seroprevalence and risk factors of Herpes simplex virus (HSV) infection in a group of female prostitutes from Mexico City. METHODS Women who consented to participate in the study voluntarily attended a sexually transmitted disease (STD) clinic during 1992. A standardized questionnaire was administered and a blood sample(More)

MATERIAL AND METHODS Sixty ASA I-III patients between 25 and 75 years old and scheduled for inguinal hernia repair were enrolled. Before the subarachnoid block, the patients were randomly assigned to(More)
