The history of the use of telemedicine in maritime medicine dates back to the 1930s. In the early 2000s, the German Navy built up a telemedicine network which today is installed in all ships and provides a connection to the medical infrastructure ashore. The objective of this study was to optimize the implementation of telemedicine based on the experience gained in the German Navy. For this purpose, qualitative and quantitative methods were used to identify determinants which affect the use of telemedicine in order to determine whether there is any need for optimization. ⋯ The study revealed determinants for the use of telemedicine in the German Navy. Factors improving the motivation of the users should be strengthened in order to optimize the use of telemedicine. Furthermore, it can be assumed that a successful implementation will be supported by reducing or eliminating obstacles. The findings on the main reasons for seeking medical advice could be taken into account in the further planning of specific training.

The combat penetrating gunshot injury is frequently associated with damage to the liver. Bile leak and external biliary fistula (EBF) are common complications. Biliary decompression is commonly applied for the management of EBF. ⋯ A scheduled ERCP application is an effective approach for the management of EBF, and liver resection could be avoided. A successful biliary decompression was achieved by the transpapillary intervention with the installation of stents. Stent occlusion could be diagnosed in the early post-traumatic period, which is effectively managed by scheduled ERCP as well as stent replacement with a large diameter as close as possible to the place of bile leak.

Weight status perception (WSP) is the subjective assessment of one's own body weight. It is not correlated with the body mass index (BMI). People practicing sports, including overweight people, tend to perceive themselves as normal weight. The military is in a paradoxical position between the need to gain muscle mass for professional purposes while respecting BMI standards. Using body composition might be more advantageous than using BMI as part of an individual approach in making a decision about fitness to serve. However, measuring body composition is not easy in current practice, and a bridge between WSP and body composition would make it possible to develop a simple assessment tool. ⋯ We were able to show a statistically significant association between WSP and Fat%. Such an association may be of great interest because the measurement of the Fat%, whatever the method used, is not easy in current practice. A replication of the study in the general population would be of great interest, especially since Fat% is closely associated with the incidence of cardiovascular diseases and many cancers.

The incidence of and risk factors for exertional heat illness (EHI) and cold weather injury (CWI) in the U.S. Army have been well documented. The "heat season", when the risk of EHI is highest and application of risk mitigation procedures is mandatory, has been arbitrarily defined as May 1 through September 30, while the "cold season" is understood to occur from October 1 to April 30 each year. The proportions of EHI and CWI that occur outside of the traditional heat and cold seasons are unknown. Additionally, it is unknown if either of the seasonal definitions are appropriate. The primary purpose of this study was to determine the proportion of EHI and of CWI that occur within the commonly accepted seasonal definitions. We also report the location-specific variability, seasonal definitions, and the demographic characteristics of the populations. ⋯ The present study indicates that the traditional heat season definition should be revised to begin ∼3 weeks earlier than the current date of May 1; our data indicate that the current cold season definition is appropriate. Inter-installation variability in the start of the cold season was much larger than that for the heat season. Exertional heat illnesses are a year-round problem, with ∼17% of all cases occurring during non-summer months, when environmental heat strain and vigilance are lower. This suggests that EHI mitigation policies and procedures require greater year-round emphasis, particularly at certain locations.

Skin Malignancy in the Military: A Number Needed to Biopsy Analysis.
Skin malignancy has increased in prevalence over the last 15 years and effective diagnosis is required for adequate treatment. Retrospective data analysis of skin biopsy data has shown correlation between various independent variables, but no studies have been shown to directly assess skin malignancy risks for military personnel. Assessing correlation could lead to more effective, targeted screening programs that could lead to decreased mortality from skin malignancies. We present a 1-year analysis of the number needed to biopsy (NNB) to detect skin cancer and analysis of military-specific risk factors in a military dermatology training program. The present study aims to (1) compare skin biopsy yields to civilian institutions and patient populations and (2) determine significance of exposure variables including age, gender, military beneficiary status, branch of service, and military rank. ⋯ The proportion of melanoma skin cancers is notably increased in our population compared to published population statistics with comparable total biopsy yields. Skin biopsy for purpose of screening for malignancy should be performed in the military population and consideration should be made for gender, age, and rank. Our findings can further expand on military risk factors for skin cancer and aid in further multivariant modeling.
