Pain relief following genicular nerve radiofrequency ablation: does knee compartment matter?

Aim: To investigate the effect of knee osteoarthritis (OA) compartment location on pain relief following genicular radiofrequency ablation. Materials & methods: A retrospective chart review was performed on 62 patients. Visual analog scale scores at 3 and 6 months post procedure were compared with baseline and between compartment groups. Results: Pain significantly improved for all patients at 3 and 6 months (p < 0.001 and p = 0.005, respectively). Medial compartment OA was a significant predictor of improvement at 3 months (p = 0.042). Patellofemoral compartment OA was a significant predictor for a higher visual analog scale at 3 months (p = 0.018). Conclusion: Compartmental location of knee OA impacts pain relief following genicular radiofrequency ablation. Future protocols could target nerves based on which compartments are more affected on imaging.

Lay abstract Aim: To investigate the effect of knee arthritis location on pain relief following planned nerve disruption using radiofrequency ablation (RFA). Materials & methods: This study analyzed existing records of 62 cases of patients who underwent an ablation procedure to the sensory nerves of the knee. On a scale from one to ten, pain after RFA at 3 and 6 months was compared with baseline and compared between arthritis location groups. Results: Pain decreased for all patients at 3 and 6 months. Inner knee arthritis was a predictor of pain improvement at 3 months. Arthritis of the kneecap was a predictor for worse pain at 3 months. Conclusion: Location of knee arthritis impacts pain relief following nerve disruption using RFA. Future protocols could target nerves based on arthritis location.

A Variant of Madelung Deformity: Management of the Distal Ulna Within the Carpal Canal.

Madelung deformity is a rare disease that affects the normal growth of the distal radius and occurs in 1.7% of all pediatric congenital hand deformities. It is characterized by progressive deformity and shortening of the radius at the distal radial physis owing to anomalous tethering of the ulnar-volar growth plate. The distal ulna overgrows the radius and usually displaces dorsally. As growth continues, the carpals assume a wedge shape. Deformity, pain, and functional limitations are the usual presenting problems. We report the case of a 9-year-old girl with bilateral Madelung deformity and pain, in whom initial radiographs of the right wrist showed that the right ulna was displaced volarly and in the carpal canal.

Síndrome de waterhouse friderichsen secundario a meningoccocemia fulminante / Waterhouse friderichsen secondaria to fulminant meningococemia

Neisseria meningitidis (meningococo), es un diplococo Gram negativo específico del ser humano, único reservorio conocido hasta la fecha; se clasifica en 13 serogrupos en base a la composición química de polisacárido capsular, no obstante, la enfermedad epidémica es causada por los serogrupos A, B, C, Y y W-135. En el presente caso clínico el agente patógeno aislado corresponde a la especie Neisseria meningitidis serogrupo W-135, cuya cepa no había sido aislada en 21 años en nuestro país y dicha anatomía patológica reportó hemorragia intracapsular de ambas glándulas suprarrenales secundaria al shock séptico inducido por la endotoxina específica de este patógeno(AU)

Neisseria meningitidis (meningococcus) is a Gram negative diplococcus specific to human and the only reservoir known to date; it is classified into 13 serogroups according to the chemical composition of capsular polysaccharide, however, epidemic disease is caused by serogroups A, B, C, Y and W-135. In this case we report an isolated pathogen that corresponds to serogroup W-135,This strain had not been isolated in 21 years in our country and this pathology reported intracapsular bleeding from both secondary adrenal glands to septic shock induced endotoxin specified pathogen(AU)

Los adolescentes y la salud escolar de los años noventa / Adolescents and school health in the 90's

Son numerosos los problemas que confrontan los adolescentes al a somo de los años noventa. Tienen su base en la inversión de valores; pobres hábitos nutricionales y de higiene; inestabilidad mental, emocional y social; una deficiente educación en salud, tanto de padres como de hijos y una existente integración entre las diversas agencias públicas y privadas responsables de desarrollar un equipo multidisciplinario que dé soluciones a los problemas en las diferentes fases. La Ley 70 de 1989 exige educación y actividades de prevención en todas las escuelas desde nivel elemental hasta la escuela superior como parte del currículo regular. Uege una coordinación entre los distintos proveedores de servicios desde la etapa del diseño de planificación, implantación, divulgación y evaluación. Este artículo pretende reunir hallazgos de diversas fuentes de estudio y las recomendaciones inmunentes para la toma de acción
