Activation of C-fiber nociceptors by low-power diode laser
Azevedo,Eduardo; Silva,Andressa; Martins,Raquel; Andersen,Monica L.; Tufik,Sergio; Manzano,Gilberto M.ABSTRACT Objective The evaluation of selective activation of C-fibers to record evoked potentials using the association of low-power diode laser (810 nm), tiny-area stimulation and skin-blackening. Method Laser-evoked potentials (LEPs) were obtained from 20 healthy young subjects. An aluminum plate with one thin hole was attached to the laser probe to provide tiny-area stimulation of the hand dorsum and the sti...
A brief historical note on the classification of nerve fibers
Manzano,Gilberto M.; Giuliano,Lydia M.P.; Nóbrega,João A.M.This is a brief review of the literature focused on the articles that formed the basis for the classification of the nerve fibers. Mention is also made to the origin of the nomenclature of the different motoneurons (a, b and g).
Pudendal somatosensory evoked potentials in normal women
Cavalcanti,Geraldo A.; Bruschini,Homero; Manzano,Gilberto M.; Nunes,Karlo F.; Giuliano,Lydia M.; Nobrega,Joao A.; Srougi,MiguelOBJECTIVE: Somatosensory evoked potential (SSEP) is an electrophysiological test used to evaluate sensory innervations in peripheral and central neuropathies. Pudendal SSEP has been studied in dysfunctions related to the lower urinary tract and pelvic floor. Although some authors have already described technical details pertaining to the method, the standardization and the influence of physiological variables i...
Andersen syndrome: an association of periodic paralysis, cardiac arrhythmia and...
Tengan,Célia H.; Antunes,Antonio C.; Bauab,José R.; Prado,Gilmar F.; Manzano,Gilberto M.; Gabbai,Alberto A.Andersen syndrome (AS) is a rare disease characterized by the presence of periodic paralysis (PP), cardiac arrhythmia and dysmorphic abnormalities. We report herein the first Brazilian patient presenting AS who also had obesity, obstructive sleep apnea (OSA) and daytime sleepiness. Clinical and genetic evaluation of six family members demonstrated that four had dysmorphic abnormalities but none had PP or cardia...
Pudendal nerve latency time in normal women via intravaginal stimulation
Cavalcanti,Geraldo A.; Manzano,Gilberto M.; Giuliano,Lydia M.; Nobrega,Joao A.; Srougi,Miguel; Bruschini,HomeroINTRODUCTION & OBJECTIVES: Studies of motor conduction for the efferent functional assessment of the pudendal nerve in women with pelvic dysfunctions have been conducted through researching distal motor latency times. The transrectal approach has been the classic approach for this electrophysiological examination. The objective of the present study is to verify the viability of the transvaginal approach in ...
The frequency of peripheral neuropathy in a group of HIV positive patients in B...
Zanetti,Claudia; Manzano,Gilberto M.; Gabbai,Alberto A.Peripheral neuropathy is a common neurological complication occurring in asymptomatic and symptomatic stages of HIV infection. The most common syndromes are distal symmetric polyneuropathy, inflammatory demielinating polyneuropathy, poliradiculopathy, mononeuropathy, mononeuropathy multiplex and autonomic neuropathy. PURPOSE: To evaluate the frequency of peripheral neuropathy in a group of HIV seropositive outp...
A comparison between averaged spikes and individual visually-analyzed spikes in...
Braga,Nadia I.O.; Manzano,Gilberto M.; Nóbrega,João Antonio M.PURPOSE:This study compared some morphological features of individual rolandic epileptiform discharges, used to obtain an averaged estimate, with those of the resulting estimate. METHOD: Twenty-four averaged discharges from EEGs of 24 children showing rolandic spikes were compared with 480 individual discharges used in the averaging. The analysis was based on the occurrence of tangential dipole and "double spik...
