Incidence of post-abortion psychosis: a prospective study.

Twenty-one cunsultant psychiatrists participated in a prospective study of post-abortion psychosis among a population of 1 333 000 people. During the 15-month study only a single case was reported, concerning a woman who had a history of two previous attacks of puerperal psychosis. The incidence of post-abortion psychosis was 0-3 per 1000 legal abortions. The incidence of puerperal psychosis, which was also studied as an index of validity, was 1-7 per 1000 deliveries. This conforms with currently accepted figures and indicates that the study population was representative. I suggest that physiological changes, which are probably more profound after childbirth than after abortion, may be responsible for the higher incidence of puerperal psychosis.

Plaque, caries, periodontal diseases, and acculturation among Yanomamö Indians, Venezuela.

The number of DM and d teeth and surfaces was recorded for 220 Yanomamö Indians from three groups of villages with different degrees of contact with Western culture. Specimens of plaque were taken from the teeth, transported in a holding solution, cultured, and examined for specific oral streptococci. In addition, the periodontal health and oral hygiene of one group of villagers were assessed using the Russell PI and the Greene & Vermillions OHIS. Caries experience among the Yanomamö was shown to be positively associated with exposure to Western culture. S. mutans was recovered with about the same frequency from specimens taken from the teeth of Indians living at all three village locations. However, the presence of S. mutans alone did not account for the disparity in dental caries scores. The examinees had abundant and persistent accumulations of soft deposits on their teeth accompanied by markedly inflamed gingival tissues. However, periodontal pockets and loss of appreciable amounts of bone did not appear as early in life nor were they as severe as reported for some other populations which practice little oral hygiene. Those disparities in the distribution of plaque-induced oral diseases between Western populations and the Yanomamö warrant further study.
