Investigation of the possible association between nosocomial candiduria and candidaemia.

This study aimed to determine whether candiduria is associated with the occurrence of nosocomial candidaemia. In the case-control part of the study, 115 cases (nosocomial candidaemia) and 115 controls (nosocomial bacteraemia) were similar in age, severity of condition and time of hospitalisation. There was a significant association of candidaemia with candiduria (OR 9.

Emergence of resistance in Pseudomonas aeruginosa and Acinetobacter species after the use of antimicrobials for burned patients.

Objectives: To evaluate the emergence of resistance of Pseudomonas aeruginosa and Acinetobacter species to imipenem, ciprofloxacin, or both after the use of these drugs and to compare resistant with susceptible isolates by molecular typing.

Design: Cohort study.

Setting: Burn intensive care unit (ICU) with 4 beds in a tertiary-care university hospital.

[A cancer mortality pattern in Brazilian electrical workers].

This study provides the cancer mortality pattern for a cohort of 10,017 electric power plant workers from 1978 to 1994. Standard mortality ratio (SMR) analysis showed lower mortality from all causes (0.47: 0.

[Blood alcohol content prevalence among trauma patients seen at a level 1 trauma center].

Objective: To investigate the prevalence of blood alcohol content (BAC) among patients seen at a level 1 trauma center.

Methods: A cross-sectional study was carried out and patients were randomly selected at the emergency room of a level I trauma center in the city of São Paulo, Brazil, throughout a year (August 1998 to August 1999). Blood samples were drawn and data was collected using an adapted version of a questionnaire developed by the Medical Research Institute of San Francisco - Alcohol Research Group.

Prognostic factors of the results of cardiopulmonary resuscitation in a cardiology hospital.

Objective: To analyze the early and late results of cardiopulmonary resuscitation in a cardiology hospital and to try to detect prognostic determinants of both short- and long-term survival.

Methods: A series of 557 patients who suffered cardiorespiratory arrest (CRA) at the Dante Pazzanese Cardiology Institute over a period of 5 years was analyzed to examine factors predicting successful resuscitation and long-term survival.

Results: Ressuscitation maneuvers were tried in 536 patients; 281 patients (52.

An outbreak of multiresistant Acinetobacter baumanii in a university hospital in São Paulo, Brazil.

A case-control (46 cases, 23 controls) study was done to determine risk factors for an outbreak of a multiresistant Acinetobacter baumanii (only susceptible to colistin) in a university hospital. The use of antecedent antibacterials and intubation were independent risk factors. No common source was found.

Drug resistance of M. tuberculosis isolated from patients with HIV infection seen at an AIDS Reference Center in São Paulo, Brazil.

M. tuberculosis-positive cultures were obtained from 228 patients seen in our service and drug sensitivity assays were carried out from January 1992 to December 1994. A survey of the medical records of these patients showed resistance to one or more drugs in 47 (20.

Erythroderma: analysis of 247 cases.

The profile of 247 patients with erythroderma during a 23 year period from January, 1962 through March, 1985, with a follow-up period ranging from 1 to 26 years were analysed. The patients presented with diffuse erythema, scaling and pruritus of more than 2 months' duration, and the age ranged from 16 to 60 years. Psoriasis was the most frequent underlying disease with an estimated frequency of 44.

[Neuropsychological tests of simple application for diagnosing dementia].

Thirty patients with dementia defined by DSM-III-R criteria (Alzheimer's disease (22), vascular dementia (3), Parkinson's disease, frontal lobe dementia, possible diffuse Lewy body dementia, normal pressure hydrocephalus and uncertain diagnosis), with scores below 24 points in the Mini-Mental Status Examination and more than 4 years of education were submitted to a neuropsychological evaluation. The scores in the neuropsychological tests were compared to those obtained by thirty normal volunteers paired for age, sex and education. Sensitivity, specificity and accuracy of the tests in the distinction of demented and normal volunteers were determined.

Platelet regeneration time: a statistical approach.

The determination of platelet regeneration half-time (PRT t1/2) by measuring malondialdehyde after intake of acetylsalicylic acid is a simple nonisotopic method for the estimation of platelet survival. There is no available information concerning the populational distribution of PRT t1/2. Consequently, there is controversy about the utilization of parametric or nonparametric statistical tests in studies of PRT.

An infant with two "half-hearts" who survived for five days: a clinical and pathological report.

The case of a five-day-old boy with two "half-hearts," diagnosed at necropsy but not clinically, is presented. Each "half-heart" was totally separated from the other and each had a single atrium and ventricle. The two "half-hearts" were enveloped in a common pericardium.
