RESUMO
Under a WHO collaborative study, the Chandigarh center monitored two geographically defined populations over a 2-year period. Using helping-agency-coverage and other methods along with a set of specified criteria, 268 first-onset potentially schizophrenic cases were actively identified. Of these, 232 cases could be assessed in detail which included 209 schizophrenics as per specified ICD-9 or Catego criteria. The annual incidence rates obtained were 4.4 and 3.8 per 10,000 for rural and urban areas, respectively. The rural cohort had a higher incidence for each of the three diagnostic definitions. In the urban cohort, sex and diagnostic definition did not affect the incidence. In the rural cohort, females had a lower incidence for Catego S+ and a higher incidence for other diagnostic definitions.
RESUMO
This paper deals with the recent epidemic of kore which occurred in four districts of Assam lasting from later part of June, 1982 to middle of September, 1982, In a survey of 83 cases including 19 females seen by the Psychiatry department of Gauhati Medical College-various socio-economic-Cultural factors and clinical symptomatology are analysed. The significant findings are : Koro affected mostly young males below 30 years belonging to Hindu Assamese community, coming from middle class families, suffering preponderantly from genital symptoms. Koro attacks mostly occurred during the night when the patients are indoor. Exposure to hearsay and/or witnessing a koro case is an important predeterminant of the episode of illness. In the series, marriage educational status and skill in occupation did not seem to offer any immunity to the victims. Relapses are few. The epidemic subsided without any fatality after massive reassurance to the public through mass media.
