Potency testing of inactivated tissue culture vaccine against Japanese encephalitis using antigen capture ELISA

A two year study of cases of chronic suppurative otitis media admitted in the Ear, Nose and Throat (ENT) Department of Sir Salimullah Medical College and Mitford Hospital from January 1991 to December 1992 was done. 112 patients of chronic suppurative otitis media (CSOM) were admitted during this two year period, out of which 100 patients (89.3%) presented with different types of complications and only 12 patients (10.7%) presented with no complications. Factors associated with the late presentation of the disorder, including poor socioeconomic conditions and lack of hospital facilities, are identified. Measures to prevent the rate of complications and hearing loss in children are suggested.
