[Mexico: evaluation of medical training based on the results of a national test given to candidates for medical residencies]. / México: evaluación de la formación de médicos con base en los resultados de un examen nacional de aspirantes a residencias médicas.

This study assesses the current status of medical education in Mexico by evaluating the IX National Medical Residency Examination. The results indicate that the personal background of the candidates is related to the probability of their passing the examination: age; marital status; number of times they have presented the examination; length of time between graduation from medical school and the examination; place where social service was performed; and work experience. The authors observe a strong tendency toward specialization in the professional curricula of the medical schools in Mexico, with a consequent neglect of the national health system's present need for primary care. They therefore suggest that the educational institutions give thought to alternatives that would better equip the country's human resources to deal with current needs.

Fiebre tifoidea: diagnostico de laboratorio, fagotipos y resistencia al cloranfenicol (1972-1982).Analisis de dos mil casos comprobados bacteriologicamente. / Typhoid fever: laboratorial diagnosis, phace types and cloramphenicol resistance (1972-1982).Analysis of 2,00 cases bacteriologically confirmed

Se analizaron dos mil casos de fiebre tifoidea cuyo diagnostico se habia podido confirmar por el aislamiento de Salmonella typhi en diferentes muestras.El cultivo de medula osea es el metodo diagnostico de eleccion, ya que los resultados obtenidos son mejores que con otras muestras, y la tasa de resultados positivos no disminuye con el tiempo de evolucion de la enfermedad, como ocurre con otros cultivos. En terminos de resistencia a los antibioticos y fagotipos, se analizaron un total de 2,685 cepas aisladas en el lapso de 1972 a 1982. A excepcion del anos 1975, la resistencia al cloranfenicol ha venido declinando y, aunque ahora la mayoria de las cepas son sensibles al cloranfenicol (94.4 por ciento en 1982), el fagotipo Vi degradado es aun el predominante
