HIV infection early diagnosis experience in primary care.

Introduction: Traditional screening system focus on classic risk factors "lost" a substantial proportion of HIV-infected patients. Several organizations such as CDC or USPS Task Force favour universal screening for HIV infection for good cost-effectiveness profile. In a previous study prevalence of HIV infection in patients attending our infectious diseases department was high (5.

Computed tomographic screening of pulmonary arterial hypertension in candidates for lung transplantation.

Introduction: Computed tomography (CT) is essential to evaluate candidates for lung transplantation (LT) We sought to correlate identification of pulmonary arterial hypertension (PAH) via CT to echocardiographic (Eco) and/or hemodynamic observations (Hd) as well as the pathological findings (Path) at posttransplant pneumonectomy.

Materials And Methods: The study included 24 consecutive months follow-up of 71 patients who were referred for LT evaluation with 54 undergoing LT. Study parameters included CT [diameter of the principal pulmonary artery (PPA) >or= 29 mm), PPA/diameter of the ascending aorta (AA) ratio > 1; diameter of the lobar artery (LA)/diameter of the lobar bronchiole (LB) ratio > 1 in three or more lobes; thickening of the anterosuperior pericardial recess (>15 mm); mosaic lung density pattern]; PAPs via Eco and/or Hd, and findings Path of PAH.

Comparison of rosuvastatin versus atorvastatin in Hispanic-Americans with hypercholesterolemia (from the STARSHIP trial).

In a multicenter, open-label trial, 696 Hispanic patients with low-density lipoprotein (LDL) cholesterol levels > or =130 and < or =300 mg/dl and triglyceride levels <400 mg/dl at medium or high risk of coronary heart disease were randomized to receive 10 or 20 mg of rosuvastatin or 10 or 20 mg of atorvastatin for 6 weeks. At week 6, LDL cholesterol was decreased more by 10 mg of rosuvastatin than by 10 mg of atorvastatin (45% vs 36%, p <0.0001) and more by 20 mg of rosuvastatin than by 20 mg of atorvastatin (50% vs 42%, p <0.

Determination of chlorinated toluenes in raw and treated water samples from the Llobregat river by closed loop stripping analysis and gas chromatography-mass spectrometry detection.

A study of the occurrence of chlorinated toluenes in Llobregat river (NE Spain) has been carried out. These compounds are currently being used in local textile industries as dye carriers and have replaced the common trichlorobenzene mixtures. Closed loop stripping analysis (CLSA), routinely used to monitor the quality of river water for a broad range of volatile compounds, has been employed as an analytical tool to determine them at ng/L levels in wastewater and textile industry effluents and also in raw and treated water from two drinking water treatment plants situated in the river course.
