Abstract Objective: To determine diabetic patients’ clinical and neurophysiological characteristics and correlate variables. Material and Methods: Fifty diabetes mellitus patients were studied at Guillermo Almenara National Hospital. Age, sex, occupation, length of disease, glycaemia, diet, treatment, sensorial symptoms, motor (SMNC) and sensorial (SMNC) nerve conduction speed of 12 nerves by patient, total 600 nerves, and prevalence of diabetic neuropathy (DN) were determined as well as the relation of the diverse variables with DN. Results: Ninety per cent of patients presented compromise, 86% fulfilled DN criteria; age was 38 to 78 years old (mean=58,5 years), 36 were males (72%), average time of disease was 89 months, glycaemia was 143 mg/dL, 74% received hypoglycaemic diet, 48% referred sensorial symptoms. There was no relation between DN and length of disease, glycaemia, treatmen...

Objective: To determine clinical and neurophysiological characteristics of carpal tunnel syndrome Material and Methods: We made a clinical-electrophysiological correlation of 381 hands pertaining to 308 patients, during four years in patients of the Neurophisiological service, Guillermo Almenara Irigoyen National Hospital (electromyography of wrist thumb short abductor, nervous conduction velocity: median nerve motor and sensitivity, nervous conduction to carpal level). Results: About 81% of patients were between 30 an 60 year-old, 53% were female, 50% had manual occupation. Symptoms and signs were parestesia, pain and Tinel syndrome. Electromyography was considered normal in 80% of cases; 50% of patients showed over 6 msec latency or inexcitability. Nervous conduction velocity of carpal level was 12,5 m/sec average. Sensitive distal latency was severely compromised in 40% of patients. C...

Presentamos el caso de una mujer de 69 años de edad con antecedente de hipertensión arterial y Síndrome de Miller Fisher recurrente hospitalizada en tres oportunidades. Las manifestaciones clínicas en sus respectivos ingresos por emergencia se caracterizaron por cefalea, diplopia y trastorno de la marcha, evidenciándose en el examen neurológico la triada clásica de oftalmoplejia, ataxia y arreflexia. Se describe los resultados de exámenes complementarios: neuroimágenes, líquido cefalorraquídeo, electromiografía y anticuerpo antigangliosido GQ1b. La recuperación de su enfermedad fue completa. En el seguimiento está asintomática.

OBJECTIVE: Neurophysiologic follow-up of 10 patients with peripheral nerves grafts. SETTING: Clinical Neurophysiology Unit, Guillermo Almenara Irigoyen National Hospital, EsSalud. MATERIAL AND METHODS: Ten 6 to 39 year-old patients with nerve grafts for peripheral nerve wounds in upper limbs were studied. Neurophysiologic control by electromyography, motor and sensitive speed nerve conduction was done periodically. RESULTS: An excellent evolution of the 10 peripheral nerve graft cases was demonstrated by the electrophysiology follow up, most of them with early recuperation of the motor nerve conduction and sensitive recuperation, as in cases of cubital lesion (cases 4, 7 and 8) and cubital and median lesions (case 10). Clinical recovery showed correlation with neurovegetative, motor and sensitive changes. CONCLUSIONS: Electrophysiology plays an important role in the evaluation of post-su...

Objetivo: Seguimiento neurofisiológico en 10 pacientes con injertos de nervios periféricos. Lugar: Unidad de Neurofisiología Clínica del Hospital Nacional Guillermo Almenara Irigoyen, EsSalud. Material y métodos: Se estudió 10 pacientes de 6 a 39 años, con lesiones de nervios periféricos en miembros superiores, en quienes se realizó injertos. Se hizo control neurofisiológico periódico con electromiografía, velocidad de conducción nerviosa motora y sensitiva. Resultado: Se encontró una excelente evolución de los 10 casos, demostrada por el seguimiento electrofisiológico, en algunos de ellos con recuperación precoz de la conducción nerviosa motora e incluso sensitiva, como en los casos de lesión cubital (casos 4, 7 y 8) y cubital y mediano (caso 10). Esta recuperación tuvo un correlato clínico, con cambios neurovegetativos, motores y sensitivos. Conclusiones: La electr...

Objective: To identify the utility, characteristics, outcome and adverse effects in the use of botulinum toxin in neurological disorders. Setting: EsSalud’s Guillermo Almenara National Hospital, Lima, Peru. Materials and Methods: One hundred and twenty-two patients received botulinum toxin type A in different neurological disorders. We determined the characteristics, outcome and adverse effects with the use of botulinum toxin. Results: The most frequent diagnosis was hemifacial spasm (63,1%), followed by spasticity (16,4%) and cervical dystonia (11,5%). The age of hemifacial spasm most frequent presentation was 60 to 69 year-old and in the left side. Torticollis and laterocollis were the most frequent types of cervical dystonia where botulinum toxin was used. There was good response in the treatment according to the favorable outcome by the TWSTRS scale performed before and 3 months po...
