[Natural history of viral hepatitis A in Chilean adults: clinical and laboratory aspects].
In many countries, Hepatitis is mainly due to virus. A. When improving life condition in a given population, initially there is a tendency to increase the number of cases in adults. We report clinical and laboratory findings in 87 adults with acute viral Hepatitis A in Chile. The rate man/woman was 1.55/1. Mean age: 23.8 years. Clinical forms: icteric classical (77.01%), cholestatic (10.34%), anicteric (8.05%), biphasic (2.30%) and fulminant (2.30%). From 87 patients in consult 1, 64 were controlled at day 15 (consult 2) and 35 one year later (consult 3). Laboratory (means): ALT (UI/L): 856.8, 111.6 and 20.8 in consult 1, 2 and 3 respectively. Correlation between values of ALT and AST (p < 0.0001). Mean total bilirubin (mg%): 6.6, 2.5 and 0.8 respectively. The evolution of Hepatitis A was favorable with a rapid decrease of clinical signs and normalization of laboratory values within the 3 first weeks of disease.

[Comparison of 4 microscopy techniques for the diagnosis of leptospirosis in wild rodents in a rural area of Valdivia, Chile].
Kidneys of six different species of 93 wild rodents captured in the rural area of Valdivia (Chile) were simultaneously examined for leptospira infection by means of Levaditi silver stain, dark ground microscopy in wet smears, and immunofluorescence and immunoperoxidase techniques using pooled antiserum against hardjo and pomona serovars. Leptospira was shown to be present in 40 (43.0%) rodents. They were detected in five of the six species: Akodon olivaceus, Akodon longipilis, Rattus rattus, Oryzomis longicaudatus and Mus musculus. Levaditi's technique detected the highest number of positive samples (67.5%) and the dark field microscopy the lowest (32.5%). The detection of leptospira in the kidneys of these wild rodents suggests that their urine may play an important role in the dissemination of leptospirosis in this area of Valdivia.
