Medical repatriations from Operation Resolute (Bosnia).

Operation Resolute is a peace enforcement mission in Bosnia-Herzegovina, which commenced on 20 December 1995. During Weeks 1-26 of the operation a total of 405 British personnel were repatriated on medical grounds, out of a mean force size of 9,299. We analysed these repatriations by clinical category and according to final destination. In addition we carried out a focused analysis of the 87 medical repatriations which occurred during May 1996. 77.5% of all the repatriations in the first 6 months of Operation Resolute were for surgical conditions, and 22.5% were medical. Eighty two per cent of British soldiers were repatriated to UK, and 18% to Germany. The mean weekly repatriation rate during this 6-month period was 1.7 per 1,000 force strength. Orthopaedic conditions were by far the greatest single cause of repatriation. During the month of May there was a total of 87 repatriations, of which 12 were due to disease. These showed no consistent pattern. Seventy five of the May repatriations were due to injury and of these 29% were caused by sport, 5% by road traffic accidents, 4% were eye injuries and one was due to burns; other occupational injuries accounted for a further 27% of the total. Twenty out of the 87 personnel repatriated in May had pre-existing medical conditions, but only 35% of these had been reviewed by their medical officer prior to deployment. Medical officers should be more diligent in carrying out pre-deployment fitness screening. The routine medical surveillance of deployed troops should be targeted towards occupational causes of injury, since these are preventable and account for terminal manpower losses.

Application of sorbent extraction chromatography to the purification of diethylstilboestrol extracted from muscle tissue and determined by radioimmunoassay.

A chromatographic procedure is described for the purification of bovine muscle tissue extracts prior to the determination of diethylstilboestrol (DES) by radioimmunoassay. Sorbent extraction chromatography of tissue extracts on reversed-phase octadecyl (C18) columns gives adequate recovery of residue and a suitable sample for radioimmunoassay. This procedure, which is simple and rapid, provides an alternative to a more complex purification by high-performance liquid chromatography. Using this method, the limit of detection for DES in muscle samples is approximately 40 pg/g.

New laws on patient treatment decisions.

These recent legislative changes should assist physicians in implementing appropriate health care decisions by patients and their families. The Natural Death Act amendments authorize the withholding and withdrawal of life-sustaining procedures from patients with incurable or irreversible conditions if death will result within a relatively short time without use of such procedures. The amendments are effective Sept 1, 1989, and apply to directives executed on or after that date. The durable power of attorney bill, effective June 14, 1989, provides a comprehensive method for allowing decision making by a surrogate. Education of the public and advance planning by principals are needed for it to be effective. Because HB 2098 requires advance execution of the power of attorney, in all likelihood most decisions to withhold or withdraw life-sustaining procedures from patients with a terminal condition will continue to be made using the procedures set forth in the Natural Death Act.
