RESUMEN
Total mercury levels were quantified in Tilapia mossambicus, Cirrhinus mrigela and Labio rohita, captured from East Calcutta Wetlands and Titagarh sewage fed aquaculture ponds. The bioconcentration factor of collected fish was assessed. Total mercury level ranged from 0.073 to 0.94 microg/g in both pre and post monsoon season. T. mossambicus in both season and C. mrigela at pre monsoon, cross the Indian recommended maximum limit (0.50 microg/g wet weight) for food consumption and according to World Health Organization guidelines all fish were not recommended for pregnant women and individuals under 15 years ages. A significant correlation was observed between mercury content of aquaculture pond water and fish muscle tissue. Total mercury concentration in experimental sites were higher than the control area (Wilcoxon Ranked-Sum test p > 0.05), which suggested the connection between mercury bioaccumulation and sewage fed aquaculture.

OBJECTIVE: To investigate the incidence and phenomenology of catatonia in a child and adolescent population. METHOD: Children and adolescents who had attended a paediatric psychiatric outpatient clinic between April and July 2001 were examined for catatonic signs with a formal catatonia rating scale, and patients who had at least two catatonic signs were included. RESULTS: Eleven patients met the criteria (5.5% of the entire sample and 17.7% of the patients with affective and nonaffective psychotic disorder); of them eight had an affective disorder and three a nonaffective disorder. The mean catatonic scores were significantly high for males and patients with mental retardation. CONCLUSION: This study shows that catatonia occurs in children and adolescents. Further studies are essential to clarify the distribution of catatonia across various diagnoses and the outcome of paediatric catatonia.
