In order to assess the prevalence of and risk factors for aminoglycoside-associated nephrotoxicity in intensive care units (ICUs), we evaluated 360 consecutive patients starting aminoglycoside therapy in an ICU. The patients had a baseline calculated glomerular filtration rate (cGFR) of > or =30 ml/min/1.73 m(2). Among these patients, 209 (58%) developed(More)
Background: the immediate effects of two semi-ocluded vocal tract exercises. Aim: to verify and compare the immediate effects of the finger kazoo (FK) and phonation with straw exercises (PS). Method: twenty-three women without vocal complaints, aged twenty-three to forty, performed the exercises twice, in a pre-set order (FK PS PS FK), and did a vocal self(More)

The effects of antihypertensive drugs on the performance of spontaneously hypertensive rats (SHR) in the elevated plus-maze were determined. Male SHR (3 months old) were submitted to long-term treatment (15 days) with alpha-methyldopa (alpha MD, 5 g/l, N = 10) and hydralazine (HYD, 100 mg/l, N = 10) given orally, diluted in water. After the drug treatment,(More)
It is currently accepted that young spontaneously hypertensive rats (SHR) have lower pressure levels than adult SHR in which the hypertension is well established, reaching the highest plateau at about 24 weeks, and that treatment with magnesium initiated during intrauterine life postpones the onset of cardiovascular alterations in SHR to about 90 days.(More)
