Recent studies described the acute diffuse external otitis frequently observed in recreational scuba-divers and swimmers in the tropics. In this study the microflora of the external auditory canal of 90 persons was determined. Additionally, a group of 17 persons was examined before, during and at the end of a two weeks vacation on a tropical coral island as well as three months after. Further, samples from sea, lagoon water and the water supplies used for the showers were microbiologically examined. 14 different and fecultatively pathogenic microorganisms were isolated from the external auditory canals. We found a temporary colonization with those microorganisms during the two weeks. Above all Pseudomonas aeruginosa was predominant during and at the end of the vacation especially in children. Before the vacation and three months after P. aeruginosa could not be found. The samples of sea and lagoon waters did not seem to be noticeably polluted, whereas the samples of the water supply were extremely contaminated with Pseudomonas aeruginosa. It was concluded that besides indirect factors such as tropical climate and intensive exposition to water, the insufficient treatment of the water from the supply could also be a reason for the temporary microbiological colonization of the external auditory canal.

Recreational Scuba

Recreational sport diving is becoming an increasingly popular sport for women. Women now comprise approximately 25% of the diving community according to Divers Alert Network statistics. In the diving literature it has been stated that women are at a greater risk for decompression sickness than men. Most of these statements were derived from high-altitude (hypobaric environment) studies rather than from a scuba diving (hyperbaric) environment. Data from the naval diving and salvage training center were analyzed, and it was found that women are not more susceptible to decompression sickness than men during dives between 4 and 10 atmospheres. More specific studies on sport diving should be completed on factors contributing to underwater decompression sickness in both men and women.

Dive computers have an important potential for citizen science projects where recreational SCUBA divers can upload the depth temperature profile and the geolocation of the dive to a central database which may provide useful information about the subsurface temperature of the oceans. However, their accuracy may not be adequate and needs to be evaluated. The aim of this study is to assess the accuracy and precision of dive computers and provide guidelines in order to enable their contribution to citizen science projects. Twenty-two dive computers were evaluated during real ocean dives for consistency and scatter in the first phase. In the second phase, the dive computers were immersed in sufficient depth to initiate the dive record inside a precisely controlled sea aquarium while using a calibrated device as a reference. Results indicate that the dive computers do not have the accuracy required for monitoring temperature changes in the oceans, however, they can be used to detect thermoclines if the users follow a specific protocol with specific dive computers. This study enabled the authors to define this protocol based on the results of immersion in two different sea aquarium tanks set to two different temperatures in order to simulate the conditions of a thermocline.

Cardiovascular factors among uninjured active adult recreational scuba divers in the USA are described. Scuba diving as an activity was included in 2011, 2013, and 2015 Behavioral Risk Factor Surveillance System data. One-third of active US scuba divers were aged ≥50 years and/or reported prior high cholesterol, around half were overweight, more than half reported having smoked cigarettes, and 32% reported hypertension or borderline hypertension. High cholesterol, hypertension, high body mass index, and smoking status should all be addressed during routine diving fitness physician assessments, to reduce the risk of mortality while diving.
