1. CERVICAL NEURENTERIC CYST: A CASE REPORT
RESUMO Objetivo Os cistos neurentéricos são responsáveis por 0.7 a 1.3% de todos os tumores da medula espinhal. Essas lesões raras são compostas por tecido endodérmico heterotópico. Métodos Uma mulher de 26 anos, com história de cervicalgia ao longo da vida, relatou história de 13 meses de piora da cervicalgia e parestesia braquial. Clinicamente,

2. The vascular and neurogenic factors associated with erectile dysfunction in patients after pelvic fractures
ABSTRACT Erectile dysfunction (ED) is a common complication of pelvic fractures. To identify the vascular and neurogenic factors associated with ED, 120 patients admitted with ED after traumatic pelvic fracture between January 2009 and June 2013 were enrolled in this study. All patients answered the International Index of Erectile Function (IIEF-5) questionn

3. Eliminação de artefatos de estímulo em potenciais evocados somatossensitivos. / Removal of stimulus artifact in somatosensory evoked potentials.
Os potenciais evocados têm uma consagrada utilização em clínica. Sua obtenção é dificultada pela presença de outros sinais biológicos, de artefatos de movimento, de ruído eletrônico, de interferência da rede elétrica e de artefatos de estímulo. A média síncrona ou promediação é um método que elimina os sinais que não estejam sincronizado

5. Ondaletas no processamento de potenciais evocados somato-sensitivos. / Wavelets in somatosensory evoked potential processing.
Os potenciais evocados somato-sensitivos são úteis para detectar e localizar lesões nas vias sensoriais. Sua obtenção exige a média síncrona de mais de mil respostas individuais. A redução do número de estímulos elétricos para obter o potencial evocado resulta na diminuição do tempo do exame e do desconforto do paciente. O objetivo desta disser

6. Pudendal somatosensory evoked potentials in normal women
OBJECTIVE: 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 standard

7. O emprego do potencial de longa latencia (P3) no diagnostico de complicações neurologicas e psiquicas do lupus eritematoso sistemico : comparação com a avaliação clinica e neuropsicologica
In an attempt to correlate neurological and neuropsychological findings with long-latency (endogenous) evoked potentials parameters, thirty-three female patients with a diagnosis of systemic lupus erythematosus were studied as to their visual auditory (brainstem), somatosensory (short latency and cortical) and long-latency (endogenous, P300) auditory evoked

8. Potencial evocado somotossensorial por estimulação do nervo mediano nas lesões Vasculares cerebrais hemisfericas : estudos dos potenciais de media latencia em relação a lesões cerebrais documentadas por ressonancia magnetica do cranio e ao potencial N20
Middle latency somatosensory evoked potentials were recorded by electrical stimulation of the median nerve at the wrist, in 43 patients with hemispheric cerebrovascular lesions. Forty two patients were examined within the third and fourth weeks, and in one case, in the fourth month afier a stroke. Ali the lesions were documented by Magnetic Resonance Imaging

9. Electrophysiologic recordings in a patient with a discrete unilateral thalamic infarction
The electroencephalogram, and somatosensory and auditory evoked potentials were recorded from a patient, who, at necropsy, showed a restricted unilateral thalmic infarct involving predominantly the anterior and lateral thalamus. The electroencephalogram showed distinct monomorphic delta activity and a suppression of the alpha rhythm over the side of the lesi

10. Transient radiation myelopathy: spinal somatosensory evoked responses following incidental cord exposure during radiotherapy.
Serial spinal somatosensory evoked potentials were recorded in six patients undergoing radiotherapy involving incidental spinal radiation. Two patients developed transient radiation myelopathy. No abnormality was found in the somatosensory evoked potentials throughout the study.

11. Evoked potentials and contingent negative variation during treatment of multiple sclerosis with spinal cord stimulation.
Cervical somatosensory evoked potentials, brainstem evoked potentials, visual evoked potentials, and the cerebral contingent negative variation were recorded in patients with definite multiple sclerosis before, during, and after spinal cord stimulation. Improvements were seen in the cervical somatosensory and brainstem evoked potentials but neither the visua

12. Visual, cortical somatosensory and brainstem auditory evoked potentials following incidental irradiation of the rhombencephalon.
Visual, cortical somatosensory and brainstem auditory evoked potentials were recorded before incidental irradiation of the rhombencephalon and at 11 weeks and eight months after completion of treatment. No patient experienced neurological symptoms during this period. No consistent changes in evoked potentials were found. The failure to demonstrate subclinica
