Background:Studies on incidence of childhood mental disorders are extremely rare globally and there are none from India. Incidence studies though more difficult and time consuming, provide invaluable information on the pattern and causes of occurrence of mental disorders allowing opportunity for early intervention and primary prevention.Aim:This study aimed at estimating the incidence of psychiatric disorders in school children.Materials and Methods:A representative sample of school children was assessed through a two stage evaluation process involving teacher's rating (N=963) and parent rating (N=873). Children who scored below the cut-off for psychiatric disorder (N=727) on both the screening instruments were re-contacted six years later. 186 children and their families were personally available for reevaluation. All the children and their parents were re-assessed on Parent Interview Schedule; Strengths and Difficulties Questionnaire: and detailed clinical assessment by a psychiatrist. Psychiatric diagnosis was made as per ICD 10 criteria. Data on children who were found to have psychiatric disorder were compared with those who did not have psychiatric disorders.Results:20 children out of 186 followed up had psychiatric disorder giving the annual incidence rate of 18/1000/yr. Children who had disorder at follow-up did not differ from those who did not on age, gender and psychological (temperament, parental handling, life stress and IQ) parameters at baseline.Discussion:Incidence figures cannot be compared due to lack of any comparable studies. Factors associated with occurrence of new cases of psychiatric disorder and implications for future studies are discussed.

Background:The Wisconsin Card Sorting Test (WCST) has been increasingly employed as a clinical neuropsychological instrument. However, in India the use of WCST is still in a relatively preliminary stage.Aim:To analyse the utility of WCST in the Indian population.Methods:Fifty-three subjects in the age group of 20–50 years, comprising both men and women, were recruited for the study. The normality was established by administering the General Health Questionnaire as a screening instrument to evaluate their health status. The WCST was administered and the norms for various dimensions were established; these were compared with those of normal healthy individuals from the West as per the WCST manual.Results and conclusion:The significance of differences and the experience of administration have been described. The present study found highly significant differences between the means on almost all WCST scores among the Western and the Indian sample, except for the number of correct responses.

Ligature strangulations are usually homicidal. Accidental cases are quite uncommon, especially among adults. A retrospective ten-year study conducted in East Delhi revealed that in a total of 98 cases of death due to strangulation, five cases (approximately 5%) among all medico-legal deaths were of fatal ligature strangulation, involving adults who were neither intoxicated nor indulging in paraphiliac activity. The causative agent in three cases was a cycle rickshaw, in one case it was a rotatory part of a machine, and the fifth case occurred due to entanglement while tying up a cow. The cases and their autopsy findings have been described in this paper, together with the review and preventive aspects of such cases.
