Posterior mediastinal melanoma causing severe dysphagia: A case report
<p>Abstract</p> <p>Introduction</p> <p>We describe an original case of progressive severe dysphagia caused by a posterior mediastinal metastatic melanoma of unknown origin. To the best of our knowledge, such an event has never been described before in the literature.</p> <p>Case presentation</p> <p>A progressive severe dysphagia case is reported induced by a melanoma of unknown origin (metastatic to a posterior mediastinal lymph node). At the time of diagnosis, the lesion appeared as a large posterior mediastinal mass mimicking a neurogenic tumour with oesophageal involvement. After complete resection, pathological assessment of the tumour by immunohistochemistry was consistent with nodal metastatic melanoma.</p> <p>Conclusion</p> <p>This report of a posterior mediastinal lymph node melanoma is unique. The nodal origin is definitely unusual: a primary melanoma should always be carefully ruled out. In fact no other evidence, a part from the absence of the tumour elsewhere, can support the diagnosis of a primary nodal melanoma.</p
Chemoradiotherapy followed by surgery versus surgery alone in esophageal cancer patients: is it time for additional evidence?
Recent efforts to improve survival in patients with locally advanced esophageal carcinoma have combined both systemic and local therapy. However, the role of neoadjuvant chemoradiotherapy in technically operable IIa-III esophageal carcinoma is still unresolved
Gastronomy and Industrialized Food in the Aymara Communities of the Pilcuyo District, El Collao Province - Ilave -Puno-Peru
The research addresses a topic of social interest that is gastronomy and industrialized foods in the Aymara context, which with its varied forms and styles, differs from other gastronomies. The aim of the research is to present the wisdom of preparing meals and consumption of the population they produce and extent of industrialized foods. For this, the qualitative method and the technique of ethnography have been used. As a result of exploration it is noticed that in the Andes the cuisine of each day is varied (breakfast, lunch and dinner), the preparation of meals of the peasant families are based on what is done by raising agrobiodiversity, on what nature offers such as: plants, wild animals and minerals. On the other hand, industrialized food that is easily obtained in the local market. The consumption is closely related to weather stations of the agricultural year, which are: "jallupacha or ch’uxñapacha " (rainy season) and " awtipacha " (dry season)
Single center experience on talc poudrage morbidity: focus on high talc dosage
Malignant pleural effusion (MPE) is a common clinical problem of concern for most of the pneumologists and thoracic surgeons. A general consensus regarding the use of talc poudrage in treatment of MPE exists, but only few studies analyzed in detail talc insufflation related pulmonary morbidity. In particular, ARDS talc-related is caused by physical and chemical effects of the small talc particles (50% particle size <15 μm) and its occurrence is independent from the underlying disease, the quantity of talc used or the technique of talc instillation. In our series we observed 3 cases only (0.75%) of talc-related lung injury. This data strongly confirm the low rate of talc-related lung injury after talc poudrage in treatment of MPE regardless the amount of talc insufflated
Perfeccionamiento del proceso evaluativo integral para los estudiantes de la Facultad de Ciencias Médicas Guantánamo
Introducción: la evaluación del proyecto educativo que se lleva a cabo actualmente en la Facultad de Ciencias Médicas de Guantánamo no es la más adecuada. Esto se evidencia en la participación poco activa y asistemática de los dirigentes de la FEU en la elaboración y evaluación del proyecto educativo a partir de indicadores, lo que influye en la calidad del proceso de integralidad de los estudiantes. Objetivo: elaborar un libro electrónico para la evaluación del proyecto educativo del año, que favorezca el perfeccionamiento del proceso de integralidad de los estudiantes de la Facultad de Ciencias Médicas Guantánamo. Método: se realizó un estudio tipo investigación acción en el período octubre de 2015 hasta junio de 2016 con 18 profesores guías y jefes de brigada y la jefa del colectivo de año de dicha facultad, donde se empleó una metodología para el diseño del material electrónico que consta de tres hojas de cálculo, que permite a partir de indicadores diseñados evaluar los resultados del proyecto educativo, además, de permitir determinar los posibles estudiantes integrales y el cumplimiento de los objetivos propuestos en el proyecto. Resultados: se obtuvo como principal resultado la transformación del personal pedagógico favoreciendo un nuevo estilo de trabajo en función de elevarla calidad del proceso y su impacto en la formación integral de los estudiantes. Conclusiones: contribuye a perfeccionar el proceso de integralidad a partir que propicia el empleo de métodos participativos, dinámicos, democráticos, a diferencia de los que se empleaban hasta el momento, con viejos estilos
