INTRODUCTION: Insulin-dependent diabetes has been considered a scuba diving contraindication. This is currently being reconsidered for well-controlled diabetes. We developed a real-time continuous glucose monitor (CGM) to check glycemia, or blood glucose (BG), during diving, both for prospective studies and to increase diabetic diver safety, allowing for real-time control of glycemia and hypoglycemia prevention. To ensure CGM measurement accuracy we tested the method under hyperbaric conditions...

We report here the first case of liver injury in a 51-year-old man following a dive to a depth of 40 meters. He presented with typical neurological symptoms affecting the lower limbs. Five days later, he experienced delayed abdominal pain, followed by rapidly progressive liver and adjacent organ injury due to air emboli in the intrahepatic portal vein. He received supportive care and hyperbaric therapy with a U.S. Navy Treatment Table 6 and recovered. Decompression sickness is a disease of protean manifestations...

Cement pulmonary embolism is a rare complication of cement kyphoplasty. These emboli are often asymptomatic and commonly detected many years after the procedure as incidental findings on radiographic imaging. We herein report a case of a 32-year-old professional diver who was diagnosed with asymptomatic cement pulmonary emboli during his annual diving physical exam. After two years of follow-up the patient remained asymptomatic and resumed his career in professional diving, which included deep sea diving activities with no evidence of respiratory limitations or long-term complications...

Oxygen is essential to sustain life, but at a high partial pressure oxygen may cause toxicity to the human body. These injuries to the lung are known as hyperoxic acute lung injury [HALI]). To date, numerous studies have been conducted to investigate the pathogenesis of HALI, for which some hypotheses have been proposed. Accumulating evidence indicates that the renin-angiotensin system (RAS) plays an important role in the pathogenesis of some lung diseases, including acute lung injury (ALI), chronic obstructive pulmonary disease (COPD) and HALI...

BACKGROUND: Hyperbaric oxygen (HBO₂) therapy has a long history of use. However, its effect on thrombus formation is unclear. Many reports have indicated that it accelerates platelet aggregation, which suggests that it may increase thrombotic events. However, clinical trial results are inconsistent, and no previous reports have demonstrated that HBO₂therapy does in fact increase thrombotic events. Here, we used a total thrombus formation analysis system (T-TAS) to analyze changes in thrombus formation in a specimen group exposed to constant hyperbaric pressure in vitro, and a control group...

Hyperoxia induced lung injury (HILI) refers to the acute lung injury secondary to prolonged exposure to hyperoxia at elevated partial pressure. With the advent of efficient systems for delivery of high concentrations of oxygen in hospitals, the population at risk for this condition has been markedly increased. Although numerous studies have been conducted to investigate the pathogenesis of HILI, the specific mechanism is still poorly understood and some hypotheses have been proposed. Transforming growth factor β (TGF-β) is a secreted protein that controls proliferation, cellular differentiation and other functions in most cells and is a type of cytokine that plays a role in many diseases...

INTRODUCTION: Changes in visual acuity are a known side effect of hyperbaric oxygen (HBO₂). We conducted a quality improvement initiative to better quantify visual change risk and to identify possible risk factors. METHODS: Vision was checked weekly in a clinical HBO₂ population by Snellen eye chart. Visual acuity change was defined as Snellen test worsened to 20/40 or greater or by loss of 2 lines. RESULTS: Of 85 patients treated from January 2013 to February 2015 with 10 HBO₂ sessions and ≥ 2 weeks of visual acuity testing, 53 (62%) were male...

The objective of this retrospective study was to analyze the relationship between sex and prognosis after carbon monoxide (CO) poisoning. Sixty-six couples diagnosed with CO poisoning were divided into two groups according to premenopausal or postmenopausal females. The prognosis was compared between husbands and wives. A multiple-factor analysis was conducted to determine the effects of sex and age on prognosis. The wives had higher Glasgow Outcome Scale (GOS) scores (P = 0.012) and cure and improvement rate (P = 0...

Tinnitus is a phantom perception of sound in the absence of overt acoustic stimulation. The focus of our attention is a combined therapy of tinnitus. In this prospective study (2013-2014) we evaluated the data of normal-hearing patients with tinnitus treated with various treatment modalities. In Group 1 we evaluated the data of 84 patients/124 ears after six weeks of treatment with betahistine dihydrochloride (72 mg). In Group 2, we evaluated the data of 36 patients/ 55 ears unimproved from Group 1 who were then treated for six weeks with hyperbaric oxygen (HBO₂) therapy combined with gingko biloba extract (120 mg)...

INTRODUCTION: Non-arteritic anterior ischemic optic neuropathy (NAION) is one of the most widespread visually disabling diseases in the middle-aged and elderly population. It typically presents as acute painless unilateral vision loss in patients over 50 years of age. The fellow eye of NAION patients is often sequentially affected. Involvement of the second eye occurs within three years in approximately 45%-50% of patients. Currently there is no generally accepted treatment for NAION but a number of medical and surgical therapies have been proposed...

Swati Agrawal, Nishi Sharma
Idiopathic sudden sensorineural hearing loss (ISSHL), a common otologic emergency, presents mostly as an abrupt onset unilateral hearing loss, aural fullness, often with vertigo and tinnitus, usually upon awakening in the morning. Its etiopathogenesis is multifactorial, so a number of different therapeutic regimens are in practice, hyperbaric oxygen (HBO2) therapy being an effective yet underutilized one. Not all cases recover completely even after treatment. Here we describe two cases of ISSHL, diagnosed on the basis of clinical examination and pure-tone audiometry, who had a complete recovery following administration of HBO2 therapy in addition to medical treatment...

The management of sudden sensorineural hearing loss following spinal anesthesia is currently an open problem. Several strategies have been used with variable results and, to the best of our knowledge, there are no prior accounts in the literature on the use of hyperbaric oxygen therapy in the treatment of this complication. We report two cases of acute onset of unilateral hearing loss after spinal anesthesia, with significantly improved results after hyperbaric oxygen therapy. A hypothesis on the possible mechanism behind this complication is discussed...

We examined the effect of hyperbaric oxygen (HBO2) treatment on bone wound healing in a rat calvarial defect. Critical-sized defects were created in the calvaria of adult Wistar rats. The animals were divided into four groups--HBO2, normobaric oxygen, hyperbaric air, and no treatment. Treatments were performed five days a week, for two weeks. Micro-computerized tomography and histological analysis were used to evaluate the bone defects. Regenerated bone areas were calculated as the percentage of new bone in the cross-sectional area of defect...

Decompression sickness is a potentially fatal illness. Optimal treatment is dry recompression with hyperbaric oxygen. In-water recompression (IWR) offers expedited treatment but has insufficient evidence to recommend it as a treatment option. This trial compares IWR to standard surface oxygen treatment using 2D echocardiography as the semi-quantitative measurement for inert gas loading. Divers were randomly assigned to either IWR or normobaric oxygen (NBO2). A provocative dive profile to 33.5 meters for 25 minutes was used to stimulate bubble formation...
