A diver presented with total loss of vision in the left eye and right hemiparesis following a routine no-stop scuba dive to 20 metres' depth. A diagnosis of decompression illness (DCI) with acute ophthalmic artery air embolism and left carotid artery insult causing acute anterior circulatory ischaemia was made. He underwent seven hyperbaric treatments leading to a full recovery. Magnetic resonance angiography revealed an underlying left anterior cerebral artery A1 segment hypoplasia. Making a prompt diagnosis and early hyperbaric oxygen treatment are crucial to halt further tissue damage from ischaemia in central nervous system DCI...

Scuba diving with an intrathecal baclofen pump is encouraged for people with spinal cord injury who are suffering from spasticity. However, the diving depth is limited to 10 metres in this context. Proper physician and patient education in this respect is mandatory since non-compliance can lead to an irreversible loss of drug reservoir capacity due to collapse of the bottom shield. We report such an incident in a paraplegic diver diving to depths down to 30 metres' water.

Rhinologic and oral maxillofacial complications from scuba diving are common, representing approximately 35% of head and neck pathology related to diving. We performed a systematic and comprehensive literature review on the pathophysiology, diagnosis, and treatment of rhinologic and oral maxillofacial pathology related to diving. This included complications due to sinus barotrauma, barodontalgia, odontocrexis, temporomandibular joint dysfunction, partially dentulous patients, and considerations for patients following major head and neck surgery...

The availability of marine habitats maps remains limited due to difficulty and cost of working at sea. Reduced light penetration in the water hampers the use of optical imagery, and acoustic methods require extensive sea-truth activities. Predictive spatial modelling may offer an alternative to produce benthic habitat maps based on complete acoustic coverage of the seafloor together with a comparatively low number of sea truths. This approach was applied to the coralligenous reefs of the Marine Protected Area of Tavolara - Punta Coda Cavallo (NE Sardinia, Italy)...

We report a case of a 55-year-old male who experienced unilateral facial muscle paralysis upon ascent to altitude on a commercial airline flight, with resolution of symptoms shortly after descent. The etiology was determined to be facial nerve barotrauma, or facial baroparesis, which is a known but rarely reported complication of scuba diving, with even fewer cases reported related to aviation. The history and proposed pathogenesis of this unique disease process are described.

Background: The case reinforces the importance of stepping back and looking at every possibility along with multiple co-existing pathologies. It takes into account the thought process of multiple systems and a multidisciplinary team approach. Learning points to take are that decompression illness can present atypically, but one must exclude other causes. Case presentation: We present the case of a 42-year-old male from the West Midlands, UK, who attended the emergency department post-scuba diving with confusion, light-headedness, left arm weakness, and bilateral paraesthesia of the hands...

Since ancient times humans observed animal and plants features and tried to adapt them according to their own needs. Biomimetics represents the foundation of many inventions from various fields: From transportation devices (helicopter, airplane, submarine) and flying techniques, to sports' wear industry (swimming suits, scuba diving gear, Velcro closure system), bullet proof vests made from Kevlar etc. It is true that nature provides numerous noteworthy models (shark skin, spider web, lotus leaves), referring both to the plant and animal kingdom...

Providing advice for travelers embarking on long-term trips poses a challenge in travel medicine. A long duration of risk exposure is associated with underuse of protective measures and poor adherence to chemoprophylaxis, increasing the chances of acquiring infections. Recently, in our clinic, we observed an increase in the number of travelers undertaking round-the-world trips. These individuals are typically aged around 32 years and quit their jobs to embark on one-to-two-year journeys. Their destinations include countries in two or more continents, invariably Southeast Asia and Indonesia, and mostly involve land travel and visiting rural areas...

Introduction: Hyperbaric oxygen (HBO₂) therapy and use of enriched air can result in oxidative injury affecting the brain, lungs and eyes. HBO₂ exposure during diving can lead to a decrease in respiratory parameters. However, the possible effects of acute exposure to oxygen-enriched diving on subsequent spirometric performance and oxidative state in humans have not been recently described recently. We aim to investigate possible effects of acute (i) hyperbaric and (ii) hyperbaric hyperoxic exposure using scuba or closed-circuit rebreather (CCR) on subsequent spirometry and to assess the role of oxidative state after hyperoxic diving...

Many aspects of the physiological stress related to the exposure to the hyperbaric environment have been studied, but no research has been made to evaluate the impacts of scuba diving on heart rate variability (HRV). We investigated the effects of a simulated dive to 557 KPa (45 meters of salt water) for a 30-minute bottom time on the frequency and time domains estimators of HRV. Electrocardiogram records were obtained with superficial electrodes for 30 minutes before the simulated dive and, subsequently, for one hour after the dive...

Corals are hotspots of ocean microbial diversity and imbalance in the composition of coral associated microbes was mostly correlated with the emergence of climate change is driven diseases and overall stability of the reef ecosystem. Coral sampling was performed by SCUBA diving at Palk Bay (latitude 9.271580, longitude 79.132203) located in India coast. Among the 54 bacterial isolates, an isolate MGL-D26 showed comparatively high biofilm formation and was identified as Staphylococcus sciuri based on phylogenetic affiliation...

Skin lesion which develops after deep sea diving is termed as coral dermatitis. The corals are known to produce a toxic substance which when comes in to contact with human skin may elicit hypersensitive reactions. Most previous reports highlight the allergic reactions caused by deep sea diving. This is a rare case of staphylococcal skin infection in a second-year medical student caused by Staphylococcus aureus ; he reported a history of deep sea diving before being presented to the hospital with skin rashes...

Scuba diving tourism is a sustainable source of income for many coastal communities, but can have negative environmental impacts if not managed effectively. Diving on soft sediment habitats, typically referred to as 'muck diving', is a growing multi-million dollar industry with a strong focus on photographing cryptobenthic fauna. We assessed how the environmental impacts of scuba divers are affected by the activity they are engaged in while diving and the habitat they dive in. To do this, we observed 66 divers on coral reefs and soft sediment habitats in Indonesia and the Philippines...

Introduction: Scuba diving is an important marine tourism sector, but requires proper safety standards to reduce the risks and increase accessibility to its market. To achieve safety goals, safety awareness and positive safety attitudes in recreational scuba diving operations are essential. However, there is no published research exclusively focusing on scuba divers' and dive centres' perceptions toward safety. This study assessed safety perceptions in recreational scuba diving operations, with the aim to inform and enhance safety and risk management programmes within the scuba diving tourism industry...

PURPOSE: A reduction in ambient pressure or decompression from scuba diving can result in ultrasound-detectable venous gas emboli (VGE). These environmental exposures carry a risk of decompression sickness (DCS) which is mitigated by adherence to decompression schedules; however, bubbles are routinely observed for dives well within these limits and significant inter-personal variability in DCS risk exists. Here, we assess the variability and evolution of VGE for 2 h post-dive using echocardiography, following a standardized pool dive in calm warm conditions...

A 54-year-old woman presented to a Sports Physician with a 4-year history of haemochromatosis, and she had a medical history that included a congenital spondylolisthesis resulting in a fusion of L4-S1 at age 16 years, episodic mechanical low back pain and an absence of other significant musculoskeletal symptoms. On presentation, she reported 18 months of severe low back pain that started after a scuba diving trip. After the onset of this low back pain, she developed gastrointestinal symptoms from Salmonella The gastrointestinal symptoms improved with a course of antibiotics, but the back pain persisted in spite of analgesics, non-steroidal anti-inflammatories and several attempts at different conservative management...

BACKGROUND: The physiological and pathophysiological mechanisms that govern diving, both self-contained underwater breathing apparatus (SCUBA) and breath-hold diving (BH-diving), are in large part well known, even if there are still many unknown aspects, in particular about cell metabolism during BH-diving. The scope of this study was to investigate changes in glycemia, insulinemia, and the catecholamine response to BH-diving, to better understand if the insulin-stimulated glucose uptake mechanism is involved in cellular metabolism in this sport...

Vomiting and aspiration of gastric contents into the airways and lungs is a common and well-known clinicopathological entity. This phenomenon might also occur in underwater diving, where it can lead to life-threatening or fatal situations. This article presents two incidents involving diving-related vomiting with associated aspiration of gastric contents. One case, a 39-year-old commercial diver using a full-face diving mask, was fatal and the other was a 33-year-old, female recreational scuba diver in whom underwater vomiting was complicated by pulmonary aspiration of a solid foreign body (a peanut) into the right lower lobe bronchus...
