OBJECTIVES. To determíne the characteristics and satisfaction of levonorgestrel users (Norplant®) at the CHNH Family Planning Program. DESIGN: Descriptive retrospective study. MATERIAL AND METHODS: Eighty-two users to whom Norplant® was removed between January 1995 and December 1999, were included. Data was obtained from records and satisfaction was evaluated through a survey employing Likert´scale. RESULTS: Up to 71,9% ofusers were satisfied, The pregnancy rate was 0%; 70,7% of users presented a side effect, being menstrual irregularíties the most frequent (47,6%). The main advantage was protection against pregnancy at the long term (53,7%). A 59% of continuity was registered during the five years and the main causes of early removal were pregnancy desire and menstrual alterations with 23,5% in both cases. A statistical significance was found with users satisfaction in the followi...

No hay una definición universalmente aceptada de pseudoartrosis; en general se acepta que si la consolidación no se realiza en 6-8 meses, estamos frente a una pseudoartrosis. El proceso de consolidación puede ser alterado o perturbado por factores mecánicos, biológicos o una combinación de ambos. El retardo de consolidación y la pseudoartrosis, son dos procesos que difieren en su fisiopatología, pronóstico y tratamiento. El tratamiento debe ser individualizado teniendo en cuenta todos los factores presentes en el paciente, para abordar de manera integral el problema. La pseudoartrosis de los huesos largos se puede tratar con un procedimiento quirúrgico único en más del 90% de los pacientes, con buenos o excelentes resultados en la restauración del eje mecánico y longitud del miembro afectado, en 80% de los casos.

Objetivo: Determinar la utilidad del uso del clavo sólido intramedular no fresado (UTN) en el tratamiento de las fracturas diafisiarias de tibia cerradas, expuestas y en seudoartrosis. Material y métodos: Se realizó un estudio de cohorte prospectivo y longitudinal en 12 pacientes con fractura diafisiaria de tibia tratados en el servicio de traumatología del Hospital Nacional Cayetano Heredia desde febrero 2000 hasta junio del 2001. La técnica usada para colocar el UTN fue la descrita en el Manual de Técnicas Quirúrgicas de la AO. El tiempo de seguimiento total fue de 1 año. Resultados: La consolidación con el uso de este clavo se dio en promedio a las 16 semanas, no presentándose ningún caso de no unión. A pesar de que algunos de nuestros pacientes presentaron lesiones en piel y tejidos blandos, no observamos infecciones superficiales ni profundas. Por otro lado el mov...

Soft tissue sarcoma (STS) is a group of highly heterogeneous tumors of mesenchymal origin that have variable primary site locations and clinical behavior. Despite the broad diversity of STS, the standard of care involves surgical resection with or without radiation therapy (RT) to control local recurrence and systemic treatment in select cases. The complexities of STS require a critical understanding of the preoperative work-up process, surgical treatment, and postoperative management. Advanced imaging plays a vital role in the characterization of the soft tissue mass, preoperative biopsy planning, and disease staging. Surgical treatment prioritizes wide resection with negative margins, supported by newer margin classification systems for better prognosis. Further, advancements in surgical technique have enabled limb-salvage surgery to largely replace amputation in the management of thes...
