AIMS To test the influence of caffeine on the lower and upper motor neuron excitability. METHODS In Experiment A, 18 healthy subjects received 200 mg of caffeine or placebo, in a randomized, double-blind, placebo-controlled design protocol. Mean F-waves amplitude, amplitude of the motor response evoked by magnetic stimulation (MEP), MEP duration, cortical(More)
In this paper, we report an exceedingly rare complication after laparoscopic inguinal hernioplasty. A 57-year-old man was submitted to transurethral resection of the prostate followed by laparoscopic “bikini mesh” hernia repair. One year later, he presented with miccional irritative symptoms. Ultrasonography showed a vesical intraluminal foreign body and(More)
UNLABELLED Heart failure (HF) remains a major diagnostic challenge. Brain natriuretic peptide (BNP) and the N-terminal portion of proBNP (NT-proBNP) have emerged as excellent diagnostic biohumoral indicators in cardiac disease. It is not clear which of the two is superior as a diagnostic marker in HF. OBJECTIVE To compare the ability of BNP and NT-proBNP(More)
AIM Chagas' disease is an endemic parasitosis found in Latin America. The disease affects different organs, such as heart, oesophagus, colon and rectum. Megacolon is the most frequent long-term complication, caused by damage to the myoenteric and submucous plexus, ultimately leading to a functional barrier to the faeces. Patients with severe constipation(More)
AIM Lidocaine inhibits depolarization by blocking sodium and calcium influx and potassium release, abolishing the action potentials of cells in the Hiss-Purkinje system and myocit cells. As it can directly influence cardiac electric and mechanical activities, this study evaluated the efficacy of lidocaine in providing myocardial protection during(More)
