Rebiopsia de próstata, factores predictivos y resultados: Hospital Higueras de Talcahuano / Prostatic rebiopsiae, predictive factors and results: Hospital Higueras, Talcahuano

El resultado más frecuente en una biopsia de próstata es el informe negativo del patólogo, debiendo decidir respecto a insistir en la búsqueda del cáncer. La rebiopsia a pacientes con APE menor a 10 ng/ml produce 10 por ciento de casos positivos para cáncer. Presentamos nuestra experiencia en rebiopsia. El hallazgo de cáncer se concentró en el grupo de pacientes con próstatas de menos de 40 grs. Ningún nuevo caso se encontró luego de una segunda biopsia entre pacientes con próstatas mayores a 90 grs. Pensamos que en un primer procedimiento de biopsia los falsos negativos se concentran entre los pacientes con próstatas de menor tamaño. En consecuencia nosotros biopsiamos todos los casos con 12 muestras desde el primer procedimiento.

The treatment of tetanus neonatorum

1. There is still a high incidence of tetanus neonatorum. An average admission of 40 cases a year was noted from 1960-1963 in the Southern Islands Hospital2. Mortality rate used to be very high in this hospital. Prior to 1960, it was almost 100. From 1960-1962 mortality rate decreased to 70-753. The rationale of treatment is discussed with emphasis on the necessity of a direct I.V. route for tetanus antitoxin4. Forty-nine cases of tetanus neonatorum admitted in the Southern Islands Hospital from January 1963 to December 1963 were included in the study5. A survival rate of about 69.4 was noted in the study6. Higher mortality rate was noted on those with ages 5 days and below and those where treatment has been delayed over 12 hours from onset7. Cases given insufficient tetanus antitoxin may survive but with longer duration than those who received sufficient antitoxin8. Tetanus antitoxin serum of 40,000 - 80,000 units, with 40,000 - 60,000 given by direct I.V. and the rest by I.M. are sufficient for most of the severe and moderate severe cases, preferably given early at the onset of symptoms to prevent fixation of lethal amounts of toxins in the central nervous system.
