RESUMO

BACKGROUND: Gallbladder Cancer (GBC) prevalence varies among countries, associated with different geographical and genetic factors. The Mapuche ethnicity (Ethnia mostly located between the VIII and X Chilean regions) stands out in Chile due to its high GBC prevalence. Aim: To estimate the GBC prevalence in patients undergoing cholecystectomy at a public hospital in the Northern region of Chile (Tarapaca), where other ethnical groups are common. MATERIAL AND METHODS: Pathological reports of 3270 patients (72% women) who underwent cholecystectomy between January 2016 and December 2019 were revised. Subsequently, the accreditation of ethnic belonging for each patient to one of the ten native communities in Chile was requested to the National Corporation for Native Communities Development (CONADI). RESULTS: According to the analysis of pathological reports, the global GBC prevalence was 0.3 %. The prevalence in Aymaras was 0.4% and 0% in Mapuches. The distribution of ethnic origins among analyzed patients was Aymara in 14.3, Mapuche in 2.7%, Diaguita in 1.7%, Quechua in 1.3%, Atacameña in 0.2%, and Colla in 0.2%. No specific ethnic origin was found in 79% of patients. Conclusions: There was a low GBC prevalence rate in Northern Chile and among the Aymara population.

RESUMO

Resumen Introducción: Los aloinjerto cutáneos (AC) son excelentes sustitutos cutáneos temporales, sin embargo, la donación y procura de piel cadavérica, fuente habitual de AC, es baja. Objetivo: Evaluar la factibilidad de utilizar la piel proveniente de abdominoplastías como fuente de AC y su eficacia clínica. Materiales y Método: Entre el 17 de agosto de 2020 al 28 de febrero de 2021 se analizó una cohorte prospectiva de 14 pacientes femeninas sometidas a abdominoplastía por motivos estéticos, que aceptaron donar la piel del colgajo cutáneo abdominal redundante, la cual fue criopreservada. Se utilizaron los AC de piel total criopreservados (ACPTC) en 10 pacientes con diagnósticos de: pie diabético (4), laparostomía contenida (2) herida compleja extremidad inferior (2), sarcoma de cuero cabelludo recidivado (1) y melanoma (1). Resultados: Se obtuvieron 14 colgajos de piel total, los cuales fueron procesados obteniendo una superficie promedio de 302 cm2 y 8,3 láminas de distintos tamaños de utilidad clínica por paciente. En todos los pacientes en que se utilizó ACPTC hubo un prendimiento inicial del AC para posteriormente, en promedio 21 días, presentar una escara necrótica que al ser retirada presentaba un tejido vital adherido al receptor rico en fibroblastos, siendo algunos pacientes auto injertados y otros manejados con cicatrización por segunda intención como tratamiento definitivo. Discusión: Los ACPTC proporcionan una cobertura intermedia, pues una parte se integra en forma definitiva, actuando como un andamiaje biológico para la formación de una interfase sobre la cual se puede autoinjertar o dejar evolucionar con cicatrización por segunda intención y una parte es rechazada. Conclusión: La procura de piel de donante vivo, en pacientes sometidos a cirugías de contorno corporal es un proceso factible, fuente de ACPTC, los cuales permiten una nueva cobertura intermedia con múltiples aplicaciones clínicas.


Introduction: Skin allografts (SA) are outstanding temporary skin substitutes; however, cadaveric skin donation and procurement, a common source of SA, remains low. Aim: To evaluate the feasibility and clinical efficacy of using skin from abdominoplasties as a source of SA. Materials and Method: A prospective cohort was analyzed from August 17th, 2020 and February 28th, 2021, with 14 female patients submitted to abdominoplasty surgeries for aesthetic motives, who authorized skin donation from the redundant abdominal flap which was posteriorly cryopreserved. Cryopreserved total skin allografts (CTSA) was used in 10 patients with the following diagnoses: diabetic foot (4), contained laparostomy (2) complex wound of the lower limb (2), relapsing sarcoma of the scalp (1), and melanoma (1). Results: 14 CTSA were obtained, which were processed, obtaining an average area of 302 cm2 and 8.3 sheets of different sizes and clinical applications from each patient. In all patients who received CTSA, an initial attachment was observed, followed by the appearance of a necrotic scar in an average of21 days. The peeling of the latter revealed a vital tissue tightly adhered to the receptor and rich in fibroblasts. Some of the patients received autografts, and others were managed with secondary intention scarring as a definite treatment. Discussion: CTSA provide an intermediate coverage since one part is definitely adhered to, acting as a biologic scaffolding for the formation of an interface that can be autografted or left for a secondary intention scarring, and the host rejects the other portion. Conclusión: skin procurement from a living donor in patients submitted to body contour surgeries is a feasible process and significant source of CTSA, which permits a new intermediate coverage with multiple clinical uses.

RESUMO

La utilidad del ATPMgCl2 para proteger a la célula del daño por la isquemia y reperfusión en diferentes órganos ha sido demostrada en numerosos trabajos de experimentación animal y últimamente en humanos. Comunicamos nuestros resultados con la utilización de esta droga en 2 grupos de animales sometidos a isquemia por oclusión aguda de la coronaria circunfleja durante 30 min. seguidos por una reperfusión de 3 horas, uno de los grupos recibió ATPMgCl2 en los primeros 30 min. de la reperfusión. Ambos grupos de animales no tuvieron diferencias significativas en sus áreas de riesgo. Observamos una disminución significativa del tamaño del infarto del grupo tratado con la droga (N=7) en relación al grupo control (N=10) (6,5 grs. v/s 3,1 grs. respectivamente p<0,05). Cuando expresamos el área infartada como porcentaje del área en riesgo, observamos una reducción en el tamaño del infarto de 29,39% a 15,97% (p<0,05). Se observó también un efecto protector significativo en la aparición de arritmias ventriculares, específicamente taquicardias ventriculares, durante la reperfusión. Concluimos que el ATPMgCl2 es una droga útil en la reducción del tamaño del infarto agudo del miocardio utilizado en el período de la reperfusión
