Objective: To analyze the functional outcome of surgical treatment of cervical spondylotic myelopathy. Methods: A retrospective study involving 34 patients with CSM, operated from January 2014 to June 2015. The neurological status was assessed using the Nurick and modified Japanese Orthopedic Association (mJOA) scales preoperatively and at 12 months. Sex, age, time of evolution, affected cervical levels, surgical approach and T2-weighted magnetic resonance hyperintense signal were also evaluated. Results: A total of 14 men and 20 women participated. The mean age was 58.12 years. The average progression time was 12.38 months. The preoperative neurological state by mJOA was mild in 2 patients, moderate in 16 and severe in 16, with a mean of 11.44 points. The preoperative Nurick was grade II in 14 patients, grade III in 8, grade IV in 10 and grade V in 2. The T2-weighted hyperintense signal was documented in 18 patients (52.9%). The functional outcome according to the mJOA recovery rate was good in 15 patients (44.1%) and poor in 19 (55.9%). The degree of Nurick recovery was good in 20 (58.8%) and poor in 14 (41.2%). Conclusions: Decompressive surgery of the spinal cord has been shown to be effective in the treatment of cervical spondylotic myelopathy in well-selected patients. Although it is suggested that there are certain factors that correlate with functional outcome, we believe that more prospective randomized studies should be conducted to clarify this hypothesis.

Objective: The objective of this longitudinal retrospective study is to assess the efficacy and safety of total lumbar disc replacement in patients with degenerative discopathy (L3-L4, L4-L5, L5-S1). Methods: One hundred and forty-three patients with low back pain, with or without radiculopathy, who met the radiographic criteria underwent anterior arthroplasty between 2000 and 2016. The Oswestry disability index (ODI), the visual analog scale (VAS), patient satisfaction, success criteria, disc height, and range of motion of the operated segment were evaluated preoperatively and at 3, 6, 12, and 24 months following surgery. Results: There were 50 men and 93 women, with an average age of 39.5 years, 13 patients (9%) with previous discectomy. The arthroplasty was performed at level L5-S1 in 97 patients (67.8%), at level L4-L5 in 45 patients (31.5%), and at level L3-L4 in 1 patient. Between the preoperative period and 24 months following surgery, the ODI decreased by 53.86%, the VAS for low back pain decreased by 63.83%, and low back pain with radiculopathy decreased by 60.20%, all statistically significant (p ≤ 0.5). Eighty-two percent of the patients were completely satisfied and 18% were satisfied. There was an average increase in disc height of 12 mm (p <0.001). The range of motion of the affected segment increased by 4° to 7° after surgery (p <0.004). Conclusions: Lumbar arthroplasty of a segment is recommended as an effective treatment for patients with degenerative disc disease with low back pain with or without a root component who meet the inclusion criteria. Level of Evidence III, Systematic review b of Level III studies.Keywords: Lumbar region; Arthrodesis; Arthroplasty. 60,20%. Cambio estadísticamente significativo (p ≤ 0,5). El 82% completamente satisfecho y satisfecho 18%. La altura discal aumentó 12 mm promedio (p <0,001). El movimiento del segmento afectado aumentó 4° a 7° después de la cirugía (p <0,004). Conclusión: La artroplastia lumbar de un segmento se recomienda como tratamiento eficaz para pacientes con enfermedad degenerativa discal que cumplen con los criterios de inclusión y lumbalgia sola o con componente radicular. RESUMO Objetivo: Para avaliar a eficácia e a segurança da reposição do disco lombar total em pacientes com discopatia degenerativa (L3-L4, L4-L5, L5-S1

La criptococosis cerebral es una enfermedad con una prevalencia considerable aun en Latinoamérica, y según la literatura en continente africano, y en menor medida en el resto del mundo. Se trata de una enfermedad micótica asociada principalmente a cuadros de inmunodepresión, lo cual le confiere un alto riesgo de peor pronóstico en estos casos, sobretodo dada un cuadro de inmunosupresión profunda, así como parte del cuadro de síndrome de reconstitución inmune. Esta reportada en la literatura y bien esclarecido el tratamiento de acuerdo a guías actuales de manejo infectológico; sin embargo, existen casos de resistencia al tratamiento aun con los esquemas mencionados. En este artículo haremos la revisión de un caso de criptococosis multirresistente asociada a hipertensión endocraneana refractaria al manejo medico por lo cual se realiza tratamiento con colocación de catéter reservorio tipo Omaya, como parte de un sistema de derivación lumboperitoneal. Se realiza revisión de la literatura y reporte del caso.
