PURPOSE: To evaluate the efficiency of a novel device coupled with ultrassound for renal percutaneous puncture. MATERIALS AND METHODS: After establishing hydronephrosis, ten pigs had three calyxes of each kidney punctured by the same urology resident, with and without the new device ("Punctiometer"). Time for procedure completion, number of attempts to reach the calyx, puncture precision and puncture complications were recorded in both groups and compared. RESULTS: Puncture success on the first attempt was achieved in 25 punctures (83%) with the Punctiometer and in 13 punctures (43%) without the Punctiometer (p=0...

BACKGROUND: Stryphnodendron adstringens (Mar.) Coville is a native plant from Brazil, rich in phenolic compounds and used on popular medicine as a wound healing agent, in the treatment of gastric lesions and as antimicrobial. MATERIALS AND METHODS: Ultrassound-assisted extraction (UAE) was applied to extraction of epigallocatechin gallate (EGCG), total polyphenols (TP) and total tannins (TT) content from barks of Stryphnodendron adstringens (Mar.) Coville. Several operating parameters, namely extraction time (min), liquid to solid ratio (mg/mL), ethanolic strength (%, v/v), were optimized using response surface methodology (RSM) with a Box-Behnken design...

PURPOSE: To assess venous hemodynamics and quality of life at lest five years after varicose vein stripping. METHODS: We conducted a prospective study with 39 patients (63 limbs) with primary lower limbs varicose veins. Preoperatively, all patients were subjected to clinical evaluation, duplex ultrassound, air plethysmography (APG), and CIVIQ questionnaire of quality of life. By APG, venous filling index (VFI), ejection fraction (EF), and residual volume fraction (RVF) were determined...

This paper presents the results of the structured interview phase of the National Abortion Survey (PNA-interviews), describing the itineraries, methods and social and demographic profile of women who had at least one illegal abortion. Structured interviews were conducted during the years 2010 and 2011 in five state capitals (Belem, Brasilia, Porto Alegre, Rio de Janeiro and Salvador) with 122 women aged between 18 and 39 who had abortions. It is a non-probabilistic sample controlled by six parameters in accordance with level of education and age to reflect the social and demographic structure found in the PNA ballot-box questionnaire phase...
