Aetiology and Management of Bronchiolitis and Pneumonia in Childhood

Cancer in East Africa-Hutt and Burkitt CAJO has gleaned information which indicates that several non- neoplastic conditions exhibit even more striking patterns of distribution which warrant further study.The statistical purist may well comment that figures for cancer incidence based on such evidence are useless.We do not believe this to be true, and we feel that in an area such as this every factual piece of knowledge is of value. SummaryCarcinoma of the penis, Kaposi's sarcoma, squamous-cell carcinoma of the skin, oesophageal cancer, and gastric carci- noma have a variable incidence in different parts of Uganda and probably in other areas of East Africa.General statements about cancer in Africans should therefore be accepted with reserve.More accurate figures are needed before studies on aetiology can be started.These figures may be attained by a combined approach on the part of the clinician and patho- logist.Personal contact is an essential feature of such a programme.Our thanks are due first to the Ministries of Health of Uganda, Kenya, Tanzania, and Rwanda for their permission to make these safaris and to visit Government hospitals.We would also like to thank all the doctors in both Government and Mission hospitals throughout East Africa for giving up valuable time to discuss their work.Finally, we would like to thank all our colleagues in the New Mulago Hospital and the Makerere University College Medical School for their help, advice, and co-operation.We would also like to acknowledge our debt to Professor J.
