The extent of military medicine topics taught in military family practice residency programs: Part I. A survey of current military family practice residency directors.

The Military Unique Curricula (MUC) was published in 1988 as a guideline for instruction at military residencies in military-specific topics. To evaluate the degree of implementation and the perceived necessity of the MUC curricula and the attitudes and logistical factors relevant to military medicine instruction in military family practice residencies, questionnaires were sent to all 18 military family practice residency directors. The results reveal a wide range of opinions regarding the importance of military medicine and the amount of instruction of military medicine topics among the residency programs. The total number of topics taught was correlated (p < 0.05) with years as residency director, awareness of the MUC, and an opinion that the material would not be better taught at service-specific schools. There appears to have been little influence of the MUC on the curricula of military family practice residencies since its publication.

The extent of military medicine topics taught in military family practice residency programs: Part II, A survey of residency graduates from 1987-1990.

The Military Unique Curricula (MUC) was published in 1988 as a guideline for instruction at military residencies in military-specific topics. Questionnaires were sent to 464 military family practice residency graduates from 1987-1990 to evaluate the degree of implementation of the MUC and attitudes and logistical factors relevant to military medicine instruction in military family practice residencies. Analysis reveals a range of opinions regarding the importance of military medicine and the amount of instruction on military medicine topics offered among programs. The total number of topics offered for instruction was positively correlated (p < 0.05) with the time available to teach the material, a perception that the material would not be best learned at the Combat Casualty Care Course, and the presence of a specific military medicine curriculum within the residency. This survey provides baseline information for future evaluation of the influence of MUC on military medicine instruction in residency programs. Suggestions are offered to improve instruction on military medicine topics in military family practice residencies.

Operational medicine in disasters.

There are many similarities and differences between operational and disaster medicine. Over the past several years, there have been increasing requirements for the use of military and tactical law enforcement operational medicine in disaster, humanitarian assistance, and terrorist settings. Many of the TEMS techniques have a direct application to disaster medicine.

The role of telemedicine in disaster medicine.

Telecommunications from telephone and radio to two-way audio, video, facsimile (fax), and digital imaging via satellite transmission have been used in responses to disasters. Current and rapidly emerging communications technology offers the prospect of enormously expanded and more efficient application in predisaster, acute, and postdisaster rehabilitation activities. A survey of present and potential roles for telemedicine in disaster medicine will be presented with particular focus on initial on-going medical needs assessment, prevention programs, and emergency assistance for provision of emergency care of victims, care for other survivors, and public health and sanitation services. Attention will also focus on telemedicine in education and training, disaster response exercises, development of comprehensive plans, and research. Finally, the essential relationship between the routine utilization of telemedicine in predisaster health care and effective employment in disaster situations will be discussed.

Refining prehospital physical assessment skills: a new teaching technique.

Physical assessment is a critically important skill in the prehospital setting, the performance of which is complicated by adverse environmental conditions. Emergency medical technicians (EMTs), paramedics, and others providing out-of-hospital emergency health care frequently receive training that does not adequately prepare them to perform an appropriate physical assessment. This is particularly true for such providers who support special operations as combat medics, wilderness EMTs, winter emergency care technicians, or EMT-tacticals. We describe a new training technique that emphasizes tactile sensory inputs rather than visual and auditory cues. The training strongly reinforces the importance of conducting a systematic survey.

Oropouche virus. II. Epidemiological observations during an epidemic in Santarém, Pará, Brazil in 1975.

An epidemic of Oropouche fever occurred in Santarém, Pará, Brazil in 1975. In the first survey for Oropouche antibodies involving a random sample of an entire city, infection rates varied from 0-44%, depending on the specific area within the city. Women had higher infection rates than men, but this difference was statistically significant only for persons older than 10 years of age. An analysis of school data showed that pupils in the evening classes had a greater increase in absenteeism during the epidemic period than those attending morning or afternoon classes. These data are compatible with the concept that Culicoides paraensis rather than Culex pipiens quinquefasciatus is the main vector of Oropouche virus in Brazil.

Oropouche virus. III. Entomological observations from three epidemics in Pará, Brazil, 1975.

Urban epidemics of Oropouche (ORO) fever in three municipalities in Pará, Brazil were studied in 1975. Culicoides paraensis (Goeldi) were collected during each of the epidemics and there was a positive correlation, by study areas within the city of Santarém, between human seropositivity to ORO virus and population densities of C. paraensis and Culex quinquefasciatus Say. The best numerical correlation was with populations of C. paraensis. The relative absence of other species in the areas of high disease attack rates was further evidence C. paraensis were the probable vectors of ORO virus. These biting midges were found to bite readily inside of houses, with an indoor/outdoor ratio of 29%, and were most active around 1700-1800 hours. Other biological observations on C. paraensis are presented.

Hepatitis B antigen and antibody in the U.S. Army: prevalence in health care personnel.

The prevalence of Hepatitis B surface antigen (HB(S)Ag) and antibody (anti-HB(S)) seropositivity and the association of seropositivity with demographic, personal health, and professional experiences were studied in a cohort of Army Medical Department officer personnel. Serologic evidence of Hepatitis B infection was found in 5.0 per cent of personnel and was associated with age, sex, place of birth, history of hepatitis, history of blood transfusion, and previous overseas assignments. Seropositivity rates were higher for patient care oriented officer personnel, especially for those in surgical specialties, and rose with increasing professional experience. These data present a composite of risk factors operative in the acquisition of Hepatitis B seropositivity and identify a cohort for prospective study.
