Voltage-activated sodium channels play a primary role during ischemic brain edema and thus are a pharmacological target for therapy. Lidocaine, a sodium channel blocker, was tested in male Sprague-Dawley rats anesthetized with thiobarbital (60 mg·kg(-1) i.p.) and perfused i.v. with Ringer's solution (n = 9) or lidocaine (0.75 mg·kg(-1), n = 9, or 1.5 mg·kg(-1), n = 6). Two tungsten microelectrodes were implanted in the cerebral cortex to register changes in tissue impedance in response to the voltage fall of a square wave electric pulse (100 μA, 10 ms), before and after infusion of lidocaine or Ringer's solution and during global cerebral ischemia due to a respiratory arrest induced by D-tubocurarine...

It is well known that chronic treatment with lithium gives cytoprotection from ischemia and neurodegeneration. Despite the clinical relevance, the potential effects of acute lithium treatment just before and during early stages of ischemia are not well known. Brain impedance was measured in an experimental global ischemia model, to determine these potential effects and their time course,as measured in minutes. Thiobarbital anesthetized (60 mg·kg(-1), intraperitoneal injection) male Sprague-Dawley rats were infused intravenously (i...

Weight loss and malnutrition related mainly to lean mass loss can develop in advanced stages of chronic obstructive pulmonary disease (COPD) and are a clear indication of phenotypic heterogeneity. The presence of weight loss and malnutrition is associated with a worse prognosis, independently of forced expiratory volume in 1 second (FEV(1)). The most widely accepted thresholds for risk are 21 for the body mass index (BMI) and 17 and 14 for men and women, respectively, for the fat-free mass index (FFMI). The coexistence of both defines a situation of greater nutritional risk (cachexia)...

Otospongiosis is an osteodystrophy of the temporal bone, characterized by disordered neoformation and deposition of bone, characterized by the presence of a progressive conductive, sensorineural or mixed hearing loss and tinnitus. Typically, otospongiosis presents as a slowly progressive conductive hearing loss in the third to fourth decade of life. Uncommonly children and adolescents may also have conductive or sensorineural hearing loss caused by otosclerosis. We describe a case of an 11-year-old patient, with progressive unilateral conductive hearing loss for 5 years...

BACKGROUND: Small for gestational age (SGA) has been associated with decreased insulin sensitivity (IS). A possible mechanism is the postnatal development of a metabolically disadvantageous body composition (BC). AIM: To determine whether there are differences between IS and BC in girls in early puberty who were SGA (birth weight < 10th percentile) or appropriate for gestational age (AGA, 10th-90th percentile). METHODS: Age-matched (SGA/AGA) early pubertal girls (Tanner II) were recruited from local schools...

The function of respiratory muscles, and mainly inspiratory muscles, is impaired in COPD patients. Most of these impairments are essentially due to pulmonary hyperinflation that puts these muscles in a disadvantageous situation. The main consequence of this dysfunction is respiratory muscle fatigue that may cause shortness of breath, exertion intolerance, and hypoventilation with onset of hypercapnic respiratory failure. This function may be measured at the pulmonary function laboratory by means of unspecific (spirometry, pulmonary volumes) or specific tests (maxim respiratory pressures [MIP - M], transdiaphragmatic pressure, tension-time index of the diaphragm, electromyography, or endura tests)...

In coordination with the Paediatrics Department, we drew up a protocol for the "Early Detection of Hearing Loss in High-Risk Neonates" based fundamentally on the sequential application of impedanciometry and the Auditory Brain Stem Response (ABR). These are the results obtained from October 1994 to March 2001. Of the 240 children examined, we found 36 cases (15%) of severe-to-profound bilateral sensorineural hearing loss (> 60 dBs HL). 55% was associated with risk factors. However, we diagnosed only 2 of these cases of hearing loss (5...
