Range of motion physiotherapy reduces the force deficit in antagonists to denervated rat muscles.

BACKGROUND: We used a rat hindlimb model of tibial nerve transection to determine if a loss of mechanical function exists in innervated antagonists compared with denervated muscles. We tested two hypotheses: (1) denervation of the rat ankle plantar flexors results in decreased force production of the ankle dorsiflexors, and (2) daily passive ankle range of motion (ROM) physiotherapy prevents or reduces the force deficit. METHODS: Adult Lewis rats were assigned to one of three groups: (1) a sham (S) group, in which the tibial nerve was exposed but not transected; (2) a no rehabilitation (NR) group, in which a 2-cm segment of tibial nerve was excised at midthigh to denervate the ankle plantar flexors; or (3) a rehabilitation (R) group, in which a 2-cm segment of tibial nerve was excised and the animals were subjected to ankle passive ROM physiotherapy for two 5-min sessions each day. After 14 days, maximum isometric tetanic force (F(0)) and specific force (sF(0)) were measured in the extensor digitorum longus (EDL) muscle, an ankle dorsiflexor. RESULTS: Compared with those from animals in the S group, EDL muscles from animals in the NR group demonstrated a 22% decrease in both F(0) and sF(0). In the EDL from animals in the R group, daily passive ROM physiotherapy diminished the deficit in F(0) but not in sF(0). CONCLUSIONS: These data support the hypotheses that nerve injuries result in impaired mechanical function in the innervated antagonists to denervated muscles and that passive ROM physiotherapy can improve force production in these muscles.

Case report. Initial manifestation of gout after carpal tunnel release.

A carpal tunnel release was performed on a patient with recurrent carpal tunnel syndrome and asymptomatic hyperuricaemia with no prior history of gouty arthritis. Intraoperatively, the patient was found to have tenosynovitis without crystals or tophaceous deposits in the carpal tunnel. Postoperatively, the patient developed an acutely inflamed hand, which responded dramatically to anti-gout medications. We report this patient as an initial attack of gout after a carpal tunnel release.

Citologia de endocérvix: estudio comparativo entre dos métodos de obtención del material / Endocervix cytology: comparative study between 2 methods for material obtention

Se presenta un estudio comparativo entre dos métodos para obtención de material citológico de endocérvix: hisopo de algodón y cepillo (cepillo de Campos Da Paz). Se aplicaron en 61 pacientes seleccionadas, del Servicio y Cátedra de Ginecología del Hospital Central. Mendoza. Treinta presentaban imágenes colposcópicas sospechosas, las 31 restantes constituyeron el grupo control. Mediante el cepillo se detectaron 3 carcinomas que eran prácticamente asintomáticos, y en dos ellos se pudo establecer el diagnóstico de compatibilidad histológica. Por la abundancia de material obtenido, su fácil aplicación, ser económico e inocuo, aconsejamos su empleo sistemático en mujeres postmenopáusicas y en portadoras de patología cervical sospechosa
