ABSTRACT
Introducción: el objetivo de este estudio fue comunicar los resultados a mediano plazo de la resección artroscópica de gangliones dorsales de muñeca utilizando la técnica en seco. Materiales y Métodos: Se evaluó retrospectivamente a 22 pacientes (22 muñecas) con un seguimiento mínimo de 2 años. Once mujeres y 11 hombres con una edad promedio de 29 años (rango 18-57). Se realizaron evaluaciones clínicas preoperatoria, al mes de la cirugía y en el último control. Se evaluaron la movilidad y la fuerza de puño comparativas, el dolor y la función según la escala analógica visual, los puntajes funcionales QuickDASH y de Wrightington, el retorno laboral y las complicaciones intraquirúrgicas y posquirúrgicas. Seguimiento promedio: 42 meses (rango 24-60). Se realizó un análisis estadístico mediante la prueba t. Resultados: Hubo 2 recidivas del ganglión. No se registraron otras complicaciones. La movilidad y la fuerza de puño comparativas mejoraron significativamente, 99% y 100%, respectivamente. El dolor y la función también mejoraron significativamente, al igual que el puntaje QuickDASH. Según la escala de Wrightington, 18 casos resultaron excelentes; 3, buenos, y uno fue malo. Veintiuno de los 22 pacientes retornaron a sus tareas laborales sin limitaciones, 20 refirieron estar satisfechos con el resultado. Conclusión: La resección artroscópica utilizando la técnica en seco representa una alternativa segura y eficaz para el tratamiento de los gangliones dorsales de muñeca, logra aliviar el dolor, y una mejoría funcional y estética en la mayoría de los pacientes mediante una rehabilitación temprana, con una baja incidencia de recidiva.
Introduction: the purpose of this study is to describe the medium-term results of arthroscopic resection of dorsal wrist ganglia using the dry technique. Methods: Twenty-two patients (22 wrists) were retrospectively evaluated with a minimum follow-up of 2 years. Eleven women and 11 men with an average age of 29 years (range 18-57). A clinical evaluation was performed preoperatively, at one month, and at the last control visit. Comparative wrist motion and grip strength, pain and function according to the visual analogue scale, functional QuickDASH and Wrightington scores, return to work, and intra and postoperative complications were evaluated. Mean follow-up was 42 months (range 24-60). Statistical analysis was performed using t test. Results: Two cases of ganglion recurrence were observed. No other complication was reported. Wrist motion and grip strength improved significantly, reaching 99% and 100%, respectively. Pain and function also improved significantly, as the functional QuickDASH score. According to Wrightington score, 18 cases were excellent, 3 were good, and one por result. Twenty-one patients returned to their tasks without limitation, 20 of them refered to be satisfied with the final result. Conclusion: Arthroscopic resection using the dry technique represents a safe and effective alternative for the treatment of dorsal wrist ganglia, achieving pain relief, and functional and aesthetic improvement in most patients with early rehabilitation and a low incidence of recurrence.

Objective: To investigate the electrophysiology characteristics of dorsal root ganglion (DRG) neurons in rats with 2, 4, 6-trinitrobenzenesulfonic acid (TNBS)-induced colitis, so as to provide reference for a better understanding of inflammatory bowel disease(IBD). Methods: SD rats(male, 160-200 g)were randomly divided into two groups. Experimental colitis was induced in colitis group (n=5) by intracolonic administration of TNBS (40 mg/kg diluted in 70% ethanol), and control rats (n = 5) received normal saline in the same manner. Rats were sacrificed on the eighth day (acute inflammation phase) after administration of TNBS or normal saline, and the DRG neurons were obtained to investigate its electrophysiology characteristics by the whole-cell patch clamping. Results: The body weight of rats in the experimental group was significantly decreased. H-E staining showed severe damage of the intestinal mucosa glands and inflammatory cell infiltration, indiating successful model creation. The action potential threshold of DRG neurons was significantly decreased in rats with TNBS-induced colitis (P<0. 05). Conclusion: The excitability of DRG neurons is increased in rat model of TNBS-induced colitis.
ABSTRACT
L6.A longitudinal column of HRP-labeled motoneurons was found in the dorsolateral and mediolateral portions of the spinal cord,distributing in the lamina Ⅸ from the caudal L4 to the rostral L6.Additionally,the transganglionic HRP-labeled central projection axonal terminals were found to be dense in the central part of laminae Ⅰ-Ⅱ from L4 to the rostral L6,and to scatter in the central part of gracile nucleus.Conclusion HRP-labeled primary afferent and efferent innervating acupoint "Taixi"(KI 3) are DRGs of L4-L6,the dorsolateral and mediolateral motoneuron columns of L4-L6,and the centrally projecting axonal terminals of laminae Ⅰ-Ⅱ of the spinal cord and the gracile nucleus.
