Evolution of cervical cytologic changes among HIV-infected women with normal cytology in the HAART era.

The influence of HAART on the evolution to cervical squamous intraepithelial lesions (SIL) among HIV(+) women with a normal cytological test in the HAART era was studied. A retrospective cohort study (1997-2005) of HIV-infected women treated with HAART was conducted. Those with a normal cervical cytology (Papanicolaou test) and at least one subsequent test were included. Survival (time until diagnosis of SIL), univariate, and multivariate analyses were performed. A total of 133 HIV-infected patients treated with HAART were included. The incidence of SIL was 35% (47 patients). SIL was diagnosed in 36 of 110 (33%) patients with a baseline and final immunological status of >200 CD4 cells/microl and in 6 of 9 (67%) patients with a baseline and final immunological status of 200 CD4) through the follow-up was associated with a reduction of SIL

Environmental cultures and hospital-acquired Legionnaires' disease : a 5-year prospective study in 20 hospitals in Catalonia, Spain

Objective: To determine whether environmental cultures for Legionella increase the index of suspicion for legionnaires' disease (LD). Design: Five-year prospective study. Setting: Twenty hospitals in Catalonia, Spain. Methods: From 1994 to 1996, the potable water systems of 20 hospitals in Catalonia were tested for Legionella, Cases of hospital-acquired LD and availability of an "in-house" Legionella test in the previous 4 years were assessed. After the hospitals were informed of the results of their water cultures, a prospective 5-year-study was conducted focusing on the detection of new cases of nosocomial legionellosis and the availability and use of Legionella testing. Results: Before environmental cultures were started, only one hospital had conducted active surveillance of hospital-acquired pneumonia and used Legionella tests including Legionella urinary antigen in all pneumonia cases. Only one other hospital had used the latter test at all. In six hospitals, Legionella tests had been completely unavailable. Cases of nosocomial LD had been diagnosed in the previous 4 years in only two hospitals. During prospective surveillance, 12 hospitals (60%) used Legionella urinary antigen testing in house and 11 (55%) found cases of nosocomial legionellosis, representing 64.7% (11 of 17) of those with positive water cultures. Hospitals with negative water cultures did not find nosocomial LD. Conclusions: The environmental study increased the index of suspicion for nosocomial LD. The number of cases of nosocomial LD increased significantly during the prospective follow-up period, and most hospitals began using the Legionella urinary antigen test in their laboratories
