Tumors of the eye in Saudi Arabia

The geographic incidence of tumors usually uncovers the influence that environment, race and culture exert upon the prevalence of cancer. Therefore this study of tumors of the eye is presented as a baseline for Saudi Arabia between the years 1982G and 1989G. The most common malignant tumors, in decreasing order of frequency, are retinoblastoma, squamous cell carcinoma of the conjunctiva, basal cell carcinoma of the eyelid, and malignant melanoma. The most common benign tumors, in the same order, are nevi, epithelial cysts, hemangiomas and dermoid cysts. There are, in Saudi Arabia, certain unique features for retinoblastoma, squamous cell carcinoma, basal cell carcinoma and malignant melanoma. Furthermore, these conditions have distinctive incidence rates when compared with cancer incidence in Western countries

military transfusion service based on a frozen blood storage system

A military transfusion service for the Armed Forces should be organized on a national bipolar pattern, consisting of a central blood bank and regional transfusion services attached to the regional military hospitals. The service should be charged with the responsibility of procuring and managing the national blood reserve and delivering it to the theatre of military operations, its field hospitals, aeromedical transport systems and operating rooms. The transfusion service should have full capabilities for storing blood in the frozen state and its stocks must reflect the needs of the Armed Forces at war. The service should be functional in peace time to benefit day-to-day medical care and to ensure its operability under military conditions
