Review of shoulder dystocia at the Birmingham Women's Hospital.

A retrospective audit was performed of all deliveries between 1 January 1991 and 31 December 1995 at the Birmingham Women's Hospital, the main University Teaching Hospital in the West Midlands. This was performed by using the computer database of all hospital deliveries, at the Women's Hospital during the above-mentioned period, by entering a CCL code for shoulder dystocia. During that period of time there were 28 932 deliveries with a mean caesarean section rate of 16.

Health and the environment-a comparative study of agricultural and industrial workers in Nigeria.

Although several attempts have been made in the developed countries to study the effect of various environmental factors on morbidity, it is disappointing that in developing countries where very poor conditions exist, very little information is available on the subject. This study was therefore designed to examine the influence of the living and working environment on the state of health of two groups of Nigerian workers namely farmers and industrial workers. The study was carried out in two villages Badeku and Ewekoro.
