In any kind of diving there is a risk of accidents, as the move from the topside environment to underwater can affect a diver’s physiological and psychological condition. It is important to investigate dive accidents to clarify the causative factors and determine preventive measures. In this study, autopsy files of fatal dive accident cases were reviewed to evaluate demographic data, type of diving, purpose of dive, seasonal distribution, autopsy findings, and causes of death. We reviewed 56 fatal dive ac...
: Internationally it is estimated that six million people participate in self-contained underwater breathing apparatus (SCUBA) diving each year. Registries suggest a significant proportion of divers have a current or historical diagnosis of asthma. Previously individuals with asthma were prohibited from diving, however, several contemporary guidelines suggest a select population of patients with asthma may be able to dive with an acceptable degree of risk. : Divers with asthma may be at an increased risk of...
Artisanal fishermen dive for sustenance. The lifetime prevalence of decompression sickness (DCS) in this population is alarmingly high. We wanted to understand the level of decompression stress fishermen in this region of the Yucatán experience in their daily fishing effort. We used a mathematical model to quantify nitrogen-loading in a nine-tissue compartment model.
Physiological changes are induced by immersion, swimming and using diving equipment. Divers must be fit to dive. Using medication may impact the capacity to adapt to hyperbaric conditions. The aim of this systematic review is to assess the interaction of diving/hyperbaric conditions and medication and to provide basic heuristics to support decision making regarding fitness to dive in medicated divers.
Middle ear barotrauma is the most common diving-related injury. It is estimated to occur in more than 50% of experienced divers. Although divers learn how to effectively equalize their ears with various maneuvers, airway congestion may impede the ability to equalize the middle ear space via the Eustachian tube. In this case, one may have to avoid diving or abort a dive due to inability to descend. If difficulty with middle ear equalization occurs during the bottom phase of the dive, which may transpire duri...
The descent is a critical part of a dive, both physically and mentally. Pulmonary ventilation, expressed as respiratory minute volume (RMV) and heart rate (HR) were recorded during fast and slow descents to 35 meters (m) in open water while breathing compressed air, and during swimming horizontally at moderate velocity at an 11-m depth. Values of both types of descents were compared with reference values recorded at 11 m, the "plateau" phase, halfway through the 35-m dives. It is hypothesized that the "slow...
Seroprevalence of Toxoplasma gondii has been extensively studied in wild boars worldwide due to the emerging risk for human infection through meat consumption. However, this is the first study that reports toxoplasmosis seroprevalence in wild boars, wild boar hunters and their hunting dogs. The aim of the present study was to evaluate the seroprevalence of anti-T. gondii antibodies in the complex wild boars, hunting dogs and hunters, and to determine the risk factors associated with seropositivity in southe...
The relationship between dive behavior and oceanographic conditions is not well understood for marine predators, especially sea turtles. We tagged loggerhead turtles (Caretta caretta) with satellite-linked depth loggers in the Gulf of Mexico, where there is a minimal amount of dive data for this species. We tested for associations between four measurements of dive behavior (total daily dive frequency, frequency of dives to the bottom, frequency of long dives and time-at-depth) and both oceanographic conditi...
Investigation of marine mammal dive-by-dive blood distribution and oxygenation has been limited by a lack of noninvasive technology for use in freely diving animals. Here, we developed a noninvasive near-infrared spectroscopy (NIRS) device to measure relative changes in blood volume and haemoglobin oxygenation continuously in the blubber and brain of voluntarily diving harbour seals. Our results show that seals routinely exhibit preparatory peripheral vasoconstriction accompanied by increased cerebral blood...
The Dutch Journal of Medicine holds a unique and comprehensive collection of commemorative medals. In the autumn of 2018, the journal arranged an online exhibition to display an extensive part of the collection and incorporated these objects into a wider historical context. This article presents a description of part ofthe web exhibition. In the light of Willem Einthoven's (1860-1927) work, we argue that around 1900 the first signs of technological medicine were becoming apparent. By focusing on a small num...
As part of a national pilot, the Lehigh Valley Family Medicine Residency Program implemented curricular changes to emphasize family medicine identity. These changes included limiting first-year inpatient experiences, adding "interval" outpatient weeks, and increasing family physician mentorship. This study explores how postgraduate learners describe their professional identities within the context of their chosen specialty, as defined by Family Medicine for America's Health (FMAHealth).
This article offers a general discussion of the concept of false hope. Its ultimate aim is to clarify the meaning and the relevance of that concept for medicine and medical research. In the first part (Sections I-V), the concept of hope is discussed. I argue that hope is more than a combination of a desire and a belief about the probability that the desire will be fulfilled. Imagination and anticipation are as well components of hope. I also discuss if hope implies orientation to action. In the second part ...
The objective of this study is to couple the contact thermography method with a novel optimization algorithm to rapidly detect and localize the soft tissue tumor. To this end, experiments are carried out on tissue-mimicking phantoms containing resistance heaters to simulate the embedded tumors. An examiner robot is used to measure the temperature of the tissue surface. The time required for the examination of the tissue surface is reduced by developing a novel optimization algorithm called the Hunter Algori...
Individuals of many species utilise social information whilst making decisions. While many studies have examined social information in making large scale decisions, there is increasing interest in the use of fine scale social cues in groups. By examining the use of these cues and how they alter behaviour, we can gain insights into the adaptive value of group behaviours. We investigated the role of social information in choosing when and where to dive in groups of socially foraging European shags. From this ...
Few studies are available to appreciate the broad spectrum of dive-related injuries (DI), which are not limited to decompression illness (DCI) and fatalities. Studies supporting injury-management efficacy from early recognition to first-aid, final treatment and outcome are also lacking. This study aims at making an epidemiologic inventory of DI among French scuba divers.
Immersion pulmonary (IPE, also known as swimming-induced pulmonary edema, SIPE) is a condition in which pulmonary edema develops rapidly during a dive or vigorous swim. Symptoms include dyspnea and hemoptysis. Physical exam reveals typical signs of bilateral pulmonary edema, which can be confirmed radiographically or with bedside ultrasound.
