The author presents a comprehensive set of initiatives and strategies for military line and medical commanders for developing effective injury prevention programs. These are not necessarily taken from preexisting written policies and instructions. Rather, they are based on his experiences in the preventive and occupational medicine field. These recommendations are for military personnel, their dependents, and federal civilian employees, and should be applied at work, at home, and during recreation.

A 46-year-old Caucasian male USAF aviator with a 6-year history of mild essential hypertension (medical waiver for flight duty) under unsuccessful treatment with hydrochlorothiazide, dietary modification, and exercise, was subsequently trained in yoga relaxation. After 6 weeks, medication had been discontinued, and his diastolic blood pressure remained within normal levels. The patient was subsequently returned to full flight status without recurrence of diastolic hypertension at followup 6 months later. Relaxation training, of which yoga is one type, has been reported in the medical literature to have wide clinical application. It should be considered as a nonpharmacological therapy adjunct or alternative for medical disorders among personnel in occupations (e.g., aviation) where the side effects from medications are of great concern and could be disqualifying from those duties.

The laboratory procedures for a cast aluminum base denture have been presented. If an induction casting machine is not available, the "two-oven technique" works well, provided the casting arm is kept spinning manually for 4 minutes after casting. If laboratory procedures are executed precisely and with care, the aluminum base denture can be cast with good results.
Six hundred and twenty-nine cases of viral hepatitis (A, B, and NonA-NonB) were reported among a total of 768,832 United States Navy and Marine Corps personnel during 1984 and 1985 via a passive surveillance system. Cumulative incidence for all three hepatitis types was higher than those reported for the general population at the same time. Hepatitis B was the most common diagnosis within all sex, rank, and race/ethnic description categories. Enlisted medical personnel (hospital corpsmen) had a disproportionately higher incidence of hepatitis B.

Data collected during 1984 from an active animal rabies surveillance system and human rabies post-exposure prophylaxis program at the US Naval Hospital, Subic Bay Naval Facility, Philippines revealed that potential rabies exposure, most commonly from dog bites or scratches, was reported for 311 US military and civilian personnel and four Filipino employees working on the facility. Seventy-nine persons (25 per cent) required complete post-exposure prophylaxis. Brain tissue from two captured dogs implicated in attacks was subsequently found to be positive for rabies antigen on fluorescent antibody testing.
This report describes a case of tropical pyomyositis in a 25-year-old man in which gray scale ultrasound played a critical role in the diagnosis and management. A review of relevant literature is provided, and a recommended approach to the diagnosis of this disease is given.
The relations of 4 pulmonary function parameters (measured from the forced expiratory spirogram) with diving experience (in years) and indices of cigarette smoking were examined in a group of 93 healthy U.S. Navy divers. Years of diving was not significantly related to lung function. The value for pack-years of smoking was inversely associated with both percentage of predicted forced expiratory volume in 1 s (FEV1) and percentage of predicted maximal midexpiratory flow rate (MMFR). Divers who have relatively heavy smoking histories may be at greater risk for developing significant decline in pulmonary function, and diving exposure factors other than years of diving may contribute to this risk.
