ABSTRACT
Resumen La infección del muñón después de amputaciones traumáticas tiene una prevalencia hasta del 34%. Las bacterias más frecuentemente aisladas son Staphylococcus aureus, Enterobacterales como Escherichia coli; Pseudomonas aeruginosa, entre otras. Estas infecciones ocurren por la inoculación directa en el momento del trauma o por gérmenes nosocomiales; la realización de curaciones de las heridas con emplastos vegetales es una práctica aún frecuente en zonas rurales de nuestro país pero su relación con infección del sitio operatorio ha sido poco explorada en la literatura. Leuconostoc spp. es un coco Gram positivo encontrado en territorio agrícola y utilizado en la industria de alimentos. Se presenta un caso de infección de un muñón transfemoral por Leuconostoc, después de una amputación traumática del miembro inferior en una paciente previamente sana con una posible asociación a curaciones con emplastos vegetales.
Abstract Infection of a traumatic amputation stump has a prevalence of 34%. The most common bacteria isolated are Staphylococcus aureus, Pseudomonas aeruginosa and Enterobacterales such as Escherichia coli. These infections occur by direct inoculation in the moment of the trauma or by nosocomial germs. Infections secondary to manipulation of the wounds with vegetable plasters have few case reports in the literature. Leuconostoc spp. is a Gram-positive coccobacillus commonly found in agricultural territory and used in the food industry. There are few case reports in the literature about bone infections by Leuconostocs pp. We present a case of an infection of the operative site of a transfemoral stump by Leuconostoc spp. after a traumatic amputation of the lower limb in a previously healthy patient who had a possible association to cures with vegetable plasters.

Resumen Se presenta una revisión conceptual generalizada de los conformadores de entrada de sistemas de control como herramientas para eliminar vibraciones en la salida de los sistemas. Se desarrollan los diferentes tipos de conformadores como versiones mejoradas de Posicast, el conformador original. Luego se presentan las aplicaciones de Posicast en el desarrollo de sistemas electrónicos, específicamente, en circuitos de potencia y en circuitos microelectrónicos.
Abstract This work is a generalized conceptual revision of the control system input shapers. The input shapers are used to eliminate vibrations at the output of the systems. The different types of shapers are developed as improved versions of Posicast, or the original shaper. Then, Posicast applications are presented in the development of electronic systems, specifically in power circuits and microelectronic circuits.

ABSTRACT
Background: Pancreatic cancer is the tenth most prevalent cancer in world, and represents the fourth cause of cancer death. It has a five year-survival of 5%. Aim: To assess the prognostic value of PET/CT in pancreatic cancer. Material and Methods: Sixty-nine patients with pancreatic adenocarcinoma who underwent staging 18F-fluorodeoxyglucose (FDG) PET/CT between December 2008 and July 2016 were selected. Gender, age, body-mass index, laboratory tests (Ca 19-9, hemoglobin, erythrocyte sedimentation rate, liver enzymes, lactate dehydrogenase), histological differentiation of tumor, American Joint Committee on Cancer (AJCC) stage, size and 18F-FDG uptake (maximal stan-dardized uptake value [SUVmax]) of the primary tumor, nodal involvement and distant metastasis detected by PET/CT were registered. Survival was assessed using Kaplan-Meier curves, Log Rank test and Cox multivariable analysis. Results: Mortality was 66.7%, during a mean observation time of 18 months (range 20 days-66 months). Curative surgery, lack of metastases detected by PET/CT, histologically well differentiated tumors, and SUVmax ≤ 4.3 were significantly associated with a better specific survival, determined by the Log Rank test. Histological differentiation was the only variable that had a statistically significant prognostic value in the multivariable analysis. Conclusions: The detection of distant metastases and the intensity of primary tumor 18F-FDG uptake during PET/CT provide useful prognostic information in pancreatic cancer patients.

La osteoporosis se define como una enfermedad que afecta el sistema músculoesquelético y secaracteriza por disminución en la masa mineral ósea con deterioro de la microarquitectura deltejido óseo que predispone a fracturas como principal complicación.El alendronato es usado como terapia para el tratamiento de la osteoporosis. Uno de sus efectosadversos es la sobresupresión de los osteoclastos con el riesgo potencial de causar fracturaspor estrés.Se presenta un caso de una fractura femoral atraumática en una mujer de 42 años en terapia conalendronato durante seis años

Se realiza un estudio retrospectivo de enfermdead trofoblástica en el Hospital Gineco Obstétrico "Isidro Ayora" en el año 1983. Se discuten los factores que pueden influir en su génesis como edad, número de gestaciones y condiciones socioeconómicas. La incidencia para dicha parología en el año indicado es de 1 por cada 688 gestaciones
