[Study of Brazilian agricultural workers. A medico-socio-psychological study].

UNLABELLED: The general state of health of native Brazilian agricultural workers - a total of 750 people from 3 different plantations in the States of Paraná and Saso Paulo - was examined. The main interest of this study war centred on infectious and parasitic diseases, nutritional conditions as well as social, intellectual factors. OBSERVATIONS: Apart from the high number of cases of helminthiasis, amounting to 80%, the general state of health of the examined subjects was found to be good - indeed better than that of a hypothetical, comparable group of Europeans. Except for the Chagas' disease, by which 5% of the test subjects were afflicted, infectious diseases posed no serious problems. There was no case of malnutrition. The relatively lower intellectual level can not be attributed to any heriditary factor, and could definitely be improved by proper schooling. Corrective measures: Chagas: Since brick houses have replaced the wooden ones for several years, new infections are unlikely. Helminthiasis: In addition to the anthelminthic treatment, sanitary prophylactic measures should be taken. Social-intellectual factors: The following points should be emphasized: elementary schooling on the plantations; teaching at intermediary level; sewing and cooking courses; general hygience.

[Simple method for obtaining Toxocara canis antigen for the indirect immunofluorescence technic].

A simple method for the preparation of Toxocara canis antigen for the indirect immunofluorescent test is described: Embryonated Toxocara eggs are treated for 12 hours at room temperature with a 1:1 mixture of 2% NaHO and sodium hypochlorite (NaClO) solution with a concentration of 2% free chlorine in order to remove the outer layers of the egg shells. The larvae which are still enclosed in the lipid membrane are freed by mild ultrasonic treatment. Thereafter, the suspension of larvae is washed and purified in a modified Baermann apparatus. In this way large numbers of larvae in pure suspension were gained and used for the production of frozen sections for the indirect immunofluorescent test. Rabbits and mice experimentally infected with embryonated Toxocara canis eggs showed a positive serological reaction (titers between 1/10 to 1/320) in this test with Toxocara larvae as antigen, while in uninfected control animals no antibodies could be detected. The larval antigen exhibited only a weak cross reaction with sera of animals infected with Ascaris suum eggs.

Diffuse hair loss and psychiatric disturbance.

32 women complaining of diffuse alopecia were assessed by a psychiatrist, and daily hair loss and root counts were measured and compared with control women. Seven of the 32 women had severe marital difficulties, and 2 of these were overtly depressed. In these 7 women, daily hair loss and telogen counts did not differ significantly from the values for control women, whereas the remaining 25 women had a significant increase in hair loss and telogen counts. It is suggested that those women whose complaint of hair loss seems disproportionate to the objective degree of alopecia should be questioned as to symptoms of depression and marital difficulties.
