Fifty-four cases of Achromobacter xylosoxidans bacteremia diagnosed over a 10-year period in patients from 2 months to 87 years of age were reviewed. Fifty-two episodes were nosocomial. The most frequent underlying condition was neoplasm (solid or hematological). The source of infection was a contaminated intravenous catheter in 35 patients (60%) and(More)
Renal function and renal size have been studied in ten early insulin-dependent diabetic patients and in ten matched control subjects. Glomerular filtration rate, renal plasma flow and radiological kidney size were determined in each subject. Glomerular filtration rate and renal plasma flow were increased in diabetics (mean ± SD: 169.6± 16.1 and(More)
The hypercalciuria evolution and other bone metabolism parameters were evaluated in patients with tuberculosis after treatment. Twenty-two patients with tuberculosis and 54 normal subjects were studied; they consumed an average diet (calcium intake 1000 mg/day). Ten of these patients and nine normal subjects were also studied after a low calcium diet (400(More)
Toxoplasmic encephalitis in patients with the acquired immunodeficiency syndrome (AIDS) is treated classically with pyrimethamine plus sulfadiazine. Unfortunately, up to 40% of these patients are unable to complete, the course of therapy because of adverse reactions to sulfonamides. This study considers the possible usefulness of monotherapies in the(More)
The purpose of this study was to analyze the quantitation of the human immunodeficiency virus type 1 RNA (HIV-1 RNA) in the genital tract of HIV-1-infected pregnant women and to evaluate a possible correlation with the viral load in blood plasma (Spearman’s rank correlation coefficient). A total of 38 each of cervical, vaginal, and blood samples from 38(More)
Comparison was made of the aetiology and methods of diagnosis in two series of patients meeting the classic criteria ofpyrexia ofunknown origin during 1968-1981 and during 1982-1989 seen in the Department of Internal Medicine at La Paz University Hospital, Madrid, Spain. There was a statistically significant decrease in the percentage of infections and an(More)
A high incidence of visceral leishmaniasis has been documented in HIV-infected patients in endemic areas. In these patients, atypical locations and a chronic course of the disease are more frequent. Two AIDS patients with laryngeal leishmaniasis are reported. These cases are believed to be the first of this type documented in the literature. The possible(More)
Cancer is caused by a variety of factors whose study requires a large amount of data. Compiling these data is an expensive and time-consuming task which can be carried out in a better way with the support of Information and Communication Technologies (ICT). However, most epidemiologic studies take place without this support of informatics or with basic(More)
To evaluate bone mineral metabolism in HIV infected and asymptomatic patients receiving highly active antiretroviral therapy (HAART) containing protease inhibitors (PI) and naïve patients. We studied 30 asymptomatic HIV infected male patients, 13 in the naive group and 17 in the IP group, both without differences in demographics characteristics. We excluded(More)
