ABSTRACT Introduction: the process of training clinical skills to diagnose leprosy by fifth-year medical students constitutes an important element in the early diagnosis of the disease and its control. Objective: to systematize the theoretical references to support the training process of fifth year Medicine students in the diagnosis of leprosy. Methods: for data collection, articles from the pages Scielo, Google Scholar, MEDISAN, Elsevier and doctoral theses in medical education sciences, either electronic or printed were reviewed for a total of 57; out of them, 26 were selected on the subject studied. Development: Systematization was carried out on the concepts of training, skill and development linked to the dermatoneurological examination and the training process of fifth year Medicine students, as well as the contribution of this skill in the early diagnosis of leprosy. Conclusions: the systematization carried out on the training of fifth-year medical students in the diagnosis of leprosy allowed establishing an approach to their theoretical references, as well as recognizing the need to develop new teaching methods to provide them with the necessary knowledge and practice to face the challenges of the demanding hygienic-epidemiological situation with actions aimed at the patient, the family and the community.

RESUMEN Introducción: el proceso formación de habilidades clínicas para diagnosticar la lepra por estudiantes de quinto año de Medicina constituye un eslabón importante en el diagnóstico precoz de la enfermedad y su control. Objetivo: sistematizar los referentes teóricos que sustentan el proceso de formación de los estudiantes de quinto año de Medicina en el diagnóstico de la lepra. Métodos: para la recogida de la información se revisaron artículos de las páginas Scielo, Google Scholar, MEDISAN, Elsevier y tesis doctorales en ciencias de la educación médica, digitalizados e impresos para un total de 57; de ellos fueron seleccionados 26 sobre la temática estudiada. Desarrollo: se realizó una sistematización sobre los conceptos de formación, habilidad y desarrollo vinculados al examen dermatoneurológico y el proceso de formación de los estudiantes de quinto año de Medicina, así como la contribución de esta habilidad en el diagnóstico precoz de la lepra. Conclusiones: el análisis realizado sobre la formación de los estudiantes de quinto año de Medicina en el diagnóstico de la lepra permitió establecer un acercamiento a sus referentes teóricos, así como reconocer la necesidad de desarrollar nuevos métodos de enseñanza que les brinden el conocimiento y la práctica necesaria para enfrentar los retos de la demandante situación higiénico-epidemiológica con acciones dirigidas al paciente, la familia y la comunidad.

A descriptive and prospective study was carried out in 51 patients diagnosed with chronic urticaria, who were attended at the Outpatient Dermatology Department of "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital of Santiago de Cuba during the first semester of 2008 to identify the etiology of this condition. The percentage as a summary measure and the chi-square test were used, considering their significance when p <0, 05. Female sex prevailed in the case material and Helicobacter pylori-positive gastric biopsies were found.

Se efectuó un estudio descriptivo y prospectivo de 51 pacientes con diagnóstico de urticaria crónica, atendidos en la consulta de Dermatología del Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" de Santiago de Cuba, durante el primer semestre del 2008, para identificar las causas de dicha afección. Se utilizó el porcentaje como medida de resumen y la prueba del Ji al cuadrado, considerando su significación cuando p <0,05. En la casuística predominó el sexo femenino y se encontró una positividad de Helicobacter pylori en las biopsias gástricas realizadas.

Estudou-se em laboratório a influência de duas diferentes fontes de alimentação sobre oviposição, eclosão dos ovos e tempo de vida de casais de Triatoma matogrossensis. Foram observados 68 casais separados em quatro diferentes grupos, com 20, 12, 20 e 16 casais, respectivamente. Os grupos A1 e A 2 foram alimentados em pombos e os grupos C1 e C 2 em coelhos. Os casais foram mantidos em estufa a 26o ± 2oC e UR de 60-80%, com fotoperíodo de 14 horas. O maior número de ovos postos foi encontrado no grupo A1. Não houve diferença na proporção de ovos eclodidos dos grupos alimentados em coelhos ou pombos. Não foram observadas diferenças de tempo de vida entre machos e fêmeas dos quatro grupos, entretanto o grupo A1 apresentou o maior tempo de sobrevivência e o grupo C2 o menor.

A laboratory study was carried out concerning the influence of two kinds of blood-meal on egg laying, egg hatching and life span of Triatoma matogrossensis. 68 couples in 4 different groups with 20, 12, 20 and 16 individuals of each sex per group were formed. Maintained under laboratory conditions groups A1 and A2 were fed on pigeons and groups C1 and C2 were fed on rabbits. In relation to egg laying the best results were found in group A1. No differences on egg hatching were found between the groups fed on rabbits and those fed on pigeons. Concerning the life span, no differences between males and females in the 4 groups were observed but group A1 presented the longest life span and group C2 the shortest.
