Both AGE and VGE can be caused by iatrogenic gas injection. AGE usually produces stroke-like manifestations, such as impaired consciousness, confusion, seizures, and focal neurological deficits. Small amounts of VGE are often tolerated due to filtration by pulmonary capillaries; however, VGE can cause pulmonary edema, cardiac \"vapor lock,\" and AGE due to transpulmonary passage or right-to-left shunt through a patent foramen ovale. Intravascular gas can cause arterial obstruction or endothelial damage and secondary vasospasm and capillary leak. Vascular gas is frequently not visible with radiographic imaging, which should not be used to exclude the diagnosis of AGE. Isolated VGE usually requires no treatment. AGE treatment is similar to decompression sickness (DCS), with first aid oxygen followed by hyperbaric oxygen. Although cerebral AGE (CAGE) often causes intracranial hypertension, animal studies have failed to demonstrate a benefit of induced hypocapnia. An evidence-based review of adjunctive therapies is presented.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"52 1","pages":"41-53"},"PeriodicalIF":0.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144036385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies have shown a potential link between MS DCS and bone lesions, including dysbaric osteonecrosis. This article highlights the importance of early detection and management of bone damage in MS DCS patients. It is recommended that a specialist diving doctor be consulted for a comprehensive assessment to ensure an accurate diagnosis and treatment plan. Ordering a joint MRI two months after the accident is the best way to detect the presence of intraosseous edema, the main risk of which is osteonecrosis, especially if the humeral or femoral head is involved. This clinical communication highlights the need for caution when resuming diving activities after MS DCS involving the shoulder or hip, as bone involvement may complicate recovery. Hyperbaric oxygen therapy sessions have been shown to have an anti-edematous effect, which can be beneficial in accelerating intraosseous healing and limiting the risk of progression to osteonecrosis. Overall, this article underscores the critical role of the diving physician in ensuring the safe return to diving for individuals recovering from MS DCS.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"52 1","pages":"9-14"},"PeriodicalIF":0.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144005494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these employees are also exposed to numerous other hazards in their workplace that may have long- and short-term health impacts. The potential adverse impact must be assessed and risk managed by companies working with a Contract Medical Advisor (CMA) assigned to the works via a Hazard Identification and Risk Assessment (HIRA) process. The appointed CMA should visit the work site to be in a position to provide adequate input into a workplace health and safety plan by directly participating in that HIRA process. A detailed analysis follows to determine whether medical surveillance would be required for hazards that are considered potential health risks. This process is reviewed with practical examples from the literature. This review does not intend to comprehensively cover all workplace hazards and risks to health associated with diving and hyperbaric operations. It aims to introduce aspects of occupational medicine and HIRA processes to Diving Medical Examiners who have not yet considered occupational hazards beyond those related to pressure. We strongly urge those doctors to work closer with the employers of divers and compressed air workers and to consider further formal study in occupational medicine. In many countries, diving medicine doctors involved with occupational divers must also have a formal occupational medicine qualification.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"52 1","pages":"1-8"},"PeriodicalIF":0.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144051733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the literature, no evidence-based studies were found on barotraumatic injuries after ear surgery nor on non-operated ears. Therefore, Risk assessments are based on interpreting anatomical, physiological, and physical facts, the results of pressure-exposed cadaver tests, and the studies concerning follow-up observations on post-op ears after pressure exposition.Results: Critical conditions after tympanoplasty type I, temporal fascia, cartilage, perichondrium, transposition of auto-ossicles, titanium TORP and PORP, omega connector, stapes surgery, malleovestibulopexy, canal wall down (CWD) and canal wall up (CWU) after cholesteatoma, obliteration of CWD, active hearing implants CI and soundbridge are presented. Immersion depth values are represented by the pressure difference between the auditory canal and the middle ear.Discussion: Tympanoplasty type I: after the complete healing process and regular tympanometry type A, the risk is not higher than in non-operated ears. Minimal burst pressure is 35 kPa (11,71 ft or 3,57 msw) when diving without Valsalva and regular tympanic membrane (TM), 30 kPa (9,84 ft or 3,0 msw) in TM with atrophic scars. PORP: same risk as type I. TORP: risk is higher than type I: burst pressure 25 kPa (8,2 ft (2,5 msw). When the stapes footplate has contact with the matrix of the cholesteatoma, diving is contraindicated. CWU: same risk as type I. CWD: contraindication for diving. Stapes surgery: same risk as for non-operated ears with regular vestibular function (verified by tympanometry).","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"52 1","pages":"23-31"},"PeriodicalIF":0.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144023485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While different treatment profiles have been proposed, there is a paucity of literature comparing the effectiveness and risk profile associated with different pressures treating the same condition.

UHMS itself distributed the survey link. The survey period lasted from November 2022 until January 2023. Data were collected utilizing the Qualtrics platform and analyzed through Microsoft Excel.Results: A total of 265 responses were recorded. The majority responded with utilizing 2.4 ATA (35.2%) as the pressure of choice, followed by 2.0 ATA only (27.1%), and those who utilized differing therapeutic pressures (26.4%). The overwhelming choice for treatment of osteoradionecrosis (ORN) of the jaw, radiation proctitis/cystitis, diabetic foot ulcer, and chronic osteomyelitis was 2.0 ATA (68.0- 74.9%). Among listed adverse effects, myopia was the most commonly reported complication at 24.4%, followed by barotrauma (14.9%) and confinement anxiety (11.5%).Conclusions: There is currently little consensus regarding the best treatment modalities for conditions treated with HBO2.

Recently, HBO2 has emerged as a potential therapeutic option for various liver diseases, offering advantages such as improved tissue oxygenation, anti-inflammatory effects, enhanced wound healing, and potential hepatoprotective properties. Understanding the benefits of HBO2 in liver diseases can pave the way for novel therapeutic strategies and improved patient outcomes. This study aimed to investigate the hepatoprotective effect of HBO2 in arthritic rats treated with leflunomide (LEF) through anti-inflammatory and antioxidant pathways.Material and methods: 24 male Sprague-Dawley rats were divided into three groups (8 animals in each group (n = 8)). 1st group was the control group, which received no treatment. 2nd group was RA + LEF 5 mg/kg, 3rd group was RA + LEF 5 mg/kg + HBO2. Rheumatoid arthritis was induced using Complete Freund's Adjuvant (CFA). The treatment was initiated on the 10th day following induction and lasted for a total of 18 days. The impact on disease progression was assessed through histological changes, which were evaluated using hematoxylin-eosin staining, while the Anti-TNF-α antibody levels were determined.Results: TCompared with the RL group, the RLH group significantly decreases necrotic cells, Lymphocyte- rich mononuclear cells, and active anti-TNF-α .Conclusion: HBO2 showed a beneficial effect and decreased hepatotoxicity on Leflunomide-induced liver injury.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"51 4","pages":"353-359"},"PeriodicalIF":0.7,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143014853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
