Natural History of Otitis Media in the American Native

Otitis media is the leading reportable disease among the Indian and Eskimo population. In addition, its prevalence is more frequent in American natives than in Caucasians or Negroes. An attempt herewith is made to delineate the factors that account for the high prevalence of otitis media in the acute and chronic form. Secondly, the characteristic morbid complications of otitis media in this population are evaluated.

Descriptive Sense

SummaryIn a study of the evolution of behavioural symptoms in severely and profoundly mentally retarded adults in hospital over a period of six years, items of abnormal behaviour were found to be remarkably persistent. There is a high prevalence rate of psychiatric disorder in this population, when this disorder is defined in a widely descriptive sense. A substantially improved living environment, and increased staff-patient ratios, are prerequisites for improving disturbed behaviour in these patients.

Practical Implications

AbstractNew Zealand Maoris are one of five ethnic groups in developed countries known to have a high rate of ear disease, including perforation of the eardrum (CSOM). It is a strongly held belief by otolaryngologists whose practice dates back to the 1960's that the prevalence of CSOM in Maori children is gradually falling. Despite the obvious practical implications this change has not yet been documented.The aim of the study was to compare the prevalence of CSOM in two surveys conducted in 1978 and 1987 of children living in a North Island Maori community. A second aim was to examine the natural history of CSOM in these children.The raw data from the 1978 study were reviewed. Of 134 children aged 4–13,12 had CSOM. In 1987 the same age group yielded 12 children out of 250 with CSOM. The prevalence of CSOM fell from 9 per cent to 4 per cent. The incidence of new perforations in 1987 was 1.3 per cent per child per year. It is concluded there has been a fall in the rate of CSOM, although otitis media remains a significant problem for these children.The probability of a perforation healing was influenced by whether or not the perforation had been observed before: at least 35 per cent of perforations seen for the first time healed, but none of the perforations seen on two occsaions healed spontaneously. It was concluded that perforation of the eardrum can be managed conservatively at first.
