Peripheral Nerve Stimulation for Painful Mononeuropathy Secondary to Leprosy: A 12-Month Follow-Up Study.

OBJECTIVE: Leprosy affects approximately 10-15 million patients worldwide and remains a relevant public health issue. Chronic pain secondary to leprosy is a primary cause of morbidity, and its treatment remains a challenge. We evaluated the feasibility and safety of peripheral nerve stimulation (PNS) for painful mononeuropathy secondary to leprosy that is refractory to pharmacological therapy and surgical intervention (decompression). METHODS: Between 2011 and 2013 twenty-three patients with painful mononeuropathy secondary to leprosy were recruited to this prospective case series. All patients were considered to be refractory to optimized conservative treatment and neurosurgical decompression. Pain was evaluated over the course of the study using the neuropathic pain scale and the visual analog scale for pain. In the first stage, patients were implanted with a temporary electrode that was connected to an external stimulator, and were treated with PNS for seven days. Patients with 50% or greater pain relief received a definitive implantation in the second stage. Follow-ups in the second stage were conducted at 1, 3, 6, and 12 months. RESULTS: After seven days of trial in the first stage, 10 patients showed a pain reduction of 50% or greater. At 12-month follow-up in the second stage, 6 of the 10 patients who underwent permanent device implantation showed a pain reduction of 50% or greater (75% reduction on average), and two patients showed a 30% reduction in pain. Two patients presented with electrode migration that required repositioning during the 12-month follow-up period. CONCLUSIONS: Our data suggest that PNS might have significant long-term utility for the treatment of painful mononeuropathy secondary to leprosy. Future studies should be performed in order to corroborate our findings in a larger population and encourage the clinical implementation of this technique.

Tratamento pediátrico de grande queimado agudo: Manejo clínico, cirúrgico e uso de matriz de regeneração dérmica / Pediatric treatment of large acute burn: Clinical, surgical management and use of dermal regeneration matrix / Tratamiento pediátrico de gran quemado agudo: Manejo clínico, quirúrgico y uso de matriz de regeneración dérmica

Objetivo: Analisar o tratamento de queimaduras em fase aguda, conduta clínica, cirúrgica e uso de matriz de regeneração dérmica (MRD) em criança internada na Unidade de Queimados do Hospital Regional da Asa Norte (UQ-HRAN), Brasília-DF. Relato do Caso: D.M.R., 2 anos e 7 meses, masculino, vítima de queimadura por chama direta, 60% de superfície corporal acometida, 50% sendo de espessura total. Atendido inicialmente segundo Protocolo de Rotinas da UQ-HRAN, entretanto, evoluiu com piora clínica, necessitando de Unidade de Terapia Intensiva pediátrica, por 58 dias. Neste período, foi submetido a 2 escarotomias, 3 desbridamentos e 10 hemotransfusões, apresentou infecções nas áreas queimadas e variados esquemas antibióticos. Tendo em vista a extensão de áreas acometidas, restrição de áreas doadoras viáveis e impossibilidade de outros curativos, optou-se pelo implante de MRD no 16° dia de internação e, após a integração, foram realizadas 6 enxertias cutâneas. Recebeu alta no 118° dia de internação. Conclusão: Houve necessidade de assistência clínica e cuidados intensivos, além de utilização de técnica cirúrgica com implante de MRD em grande queimado agudo. Sendo assim, a MRD teve como objetivo proporcionar leito receptor de qualidade, associado a maior integração para enxertia cutânea futura, pois a carência de áreas doadoras o colocaria em risco de vida maior. Esse conjunto de fatores contribuiu para o sucesso do tratamento e a boa recuperação da criança.

Objective: To analyze the treatment of burn in acute-phase using clinical, surgical management and use of dermal regeneration matrix (DRM) in a child hospitalized at the Burn Unit of Asa Norte Regional Hospital (BU-ANRH), Brasília-DF. Case Report: D.M.R., 2 years and 7 months old, male, victim of direct fire, 60% of body surface affected, 50% full-thickness. Initially treated according to the BU-ANRH Routine Protocol, however, evolved to clinical decline, requiring a pediatric Intensive Care Therapy for 58 days. During this period, he underwent two escharotomies, three debridements and 10 blood transfusions. He exhibited infection in burned areas and used multiple antibiotic schemes. Due to the extension of affected surface, restriction of viable donor zone and unusable of other bandages, DRM was implanted on the 16th day of hospitalization and integration, he has done six cutaneous grafting. He was discharged on the 118th day of hospitalization. Conclusion: Clinical and intensive care were needed, besides the use of surgical technique with DRM implantation in a large acute burn. Thus, DRM has had as a goal to provide quality receptor bed, associated with greater integration for future cutaneous grafting, since the lack of donor areas would put it at greater risk of life. This set of factors contributed to the success of the treatment and the good recovery of the child.

Objetivo: Analizar el tratamiento de quemaduras en fase aguda, conducta médica clínica, quirúrgica y uso de matriz de regeneración dérmica (MRD) en niño internado en la Unidad de Quemados del Hospital Regional de Asa Norte (UQ-HRAN), Brasília-DF. Reporte de Caso: D.M.R., 2 años y 7 meses, masculino, víctima de quemadura de llama directa, 60% de la superficie del cuerpo afectada, 50% del espesor total. Inicialmente tratado de acuerdo con el Protocolo de Rutina UQ-HRAN, sin embargo, evolucionó con un empeoramiento clínico, necesitando cuidados en la Unidad de Terapia Intensiva pediátrica durante 58 días. Durante este período, fue sometido a 2 escarotomías, 3 desbridamientos y 10 transfusiones de sangre. Presentó infecciones en zonas quemadas y variados esquemas antibióticos. Debido a la extensión de las áreas afectadas, la restricción de las áreas viables de los donantes y la imposibilidad de otros curativos, se optó por el implante de MRD en el 16° día de internación y después de la integración, se realizaron 6 injertos cutáneos. Recibió alta en el 118° día de internación. Conclusión: Hubo necesidad de asistencia clínica y cuidados intensivos, además de utilización de técnica quirúrgica con implante de MRD en gran quemado agudo. Por lo tanto, la MRD tuvo como objetivo proporcionar lecho receptor de calidad, asociado a la mayor integración para el injerto cutáneo futuro, pues la carencia de áreas donantes lo pondría en mayor riesgo de vida. Este conjunto de factores, contribuyó al éxito del tratamiento y la buena recuperación del niño.
