{"title":"REPRINTED FROM THE 2023 HYPERBARIC INDICATIONS MANUAL 15th Edition: Sudden Sensorineural Hearing Loss.","authors":"Tracy Leigh LeGros, Heather Murphy-Lavoie","doi":"","DOIUrl":"","url":null,"abstract":"Sudden sensorineural hearing loss (SSNHL) presents as the abrupt onset of hearing loss. Approximately 88% of SSNHL has no identifiable etiology and is termed idiopathic sudden sensorineural hearing loss (ISSHL). Hearing specialists have investigated ISSHL since the 1970s. Over the past 30 years, more than 800 articles, or one every two weeks, have been published in the English medical literature. ISSHL is the abrupt onset of hearing loss, usually unilaterally and upon wakening, that involves a hearing loss of at least 30 decibels (dB) occurring within three days over at least three contiguous frequencies. As most patients do not present with premorbid audiograms, the degree of hearing loss is usually defined by the presentation thresholds of the unaffected ear. Other associated symptoms include tinnitus, aural fullness, dizziness and vertigo. The historical incidence of ISSHL ranges from 5-20 cases/100,000 population, with approximately 4,000 new cases per annum in the United States. The true incidence is thought to be higher, as ISSHL is thought to be underreported. Interestingly, 4,000 cases annually calculate to 1.3 cases/ 100,000 in the United States; therefore, an incidence of 5-20/100,000 would translate to > 15,000 new ISSHL cases per annum in the United States. Recent literature has placed the annual ISSHL incidence in the United States as 27 cases/100,000, with a pediatric incidence of 11 cases/100,000. Other studies report that the incidence is increasing (160/100,000), especially in the elderly (77/100,000), and conclude that ISSHL is no longer rare. In 1984, Byl reviewed the literature and found the mean age of ISSHL presentation to be 46-49 years, with variation of incidence with age and an equal gender distribution. The presentation of ISSHL does not appear to have seasonal variations, uneven distributions of presentation throughout the year, or an association with upper respiratory infections, either prior to or following symptom onset. The spontaneous recovery is currently thought to be 30-60%.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"51 4","pages":"425-448"},"PeriodicalIF":0.7,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143014876","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}

This case report describes the successful use of hyperbaric oxygen therapy in a patient with vascular occlusion after a permanent dermal filler was injected.Case report: A 51-year-old woman underwent an injection of non-resorbable polymethylmethacrylate microspheres into her nasolabial folds. Several hours later, she experienced dusky discoloration of the right nasolabial fold and surrounding livedo skin changes, consistent with vascular occlusion. Treatment with warm compresses and topical nitroglycerin was initiated, and the patient was referred for hyperbaric oxygen therapy. The tissue discoloration improved significantly after the administration of six hyperbaric treatments.Discussion: While hyaluronidase is recognized as a treatment option for vascular occlusion associated with using temporary fillers containing hyaluronic acid, it may also be beneficial for patients who experience vascular occlusion after administration of permanent fillers. Hyperbaric oxygen therapy, which results in hyperoxygenation of ischemic tissue and mitigation of the associated inflammatory response, may also benefit patients who experience vascular occlusion after permanent filler injection.Conclusions: Administration of hyaluronidase and hyperbaric oxygenation should be considered for patients who develop arterial occlusions after dermal filler placement, regardless of the type of injected filler.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"51 4","pages":"403-406"},"PeriodicalIF":0.7,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143014838","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}

{"title":"Recovery from pulmonary oxygen toxicity: a new (ESOT) model.","authors":"Jan Risberg, Pieter-Jan van Ooij, Lyubisa Mátity","doi":"","DOIUrl":"","url":null,"abstract":"Arieli has previously demonstrated that the exposure metric K could be used to predict pulmonary oxygen toxicity (POT) based on changes in Vital Capacity (VC). Our previous findings indicate that the Equivalent Surface Oxygen Time (ESOT) allows the estimation of POT without loss of accuracy compared to K. In this work, we have further investigated POT recovery. The K metric assumes that the recovery of POT is to be controlled by exposure to pO2. This results in a counterintuitively slow estimated recovery after exposure to low pO2. Similarly, K overestimates POT during intermittent hyperoxic exposures. We used results from previous studies to train the parameters of a new ESOT recovery model. The predicted recovery of ESOT (ESOTrec) after initial hyperoxic exposure (ESOTI) of duration texp (h) and recovery time t (h) can be calculated as ESOTrec=ESOTI · e-f with f=0.439 · t · 0.906texp. For intermittent exposures, the function ESOT(n)=(n · a · ln(b · n+1)+c) · texp · pO22.285 will approximate POT (ESOT(n)) after n sessions of pO2 (atm) for time texp (min) in each cycle. Parameters a, b, and c are specific for each cycling pattern. These ESOT functions will better predict the development of POT during intermittent hyperoxic exposures as well as recovery after a broader range of continuous hyperoxic exposures than K. We recommend limiting hyperoxic exposures in surface-oriented diving to ESOT=660, 500, and 450 for a maximum of one, five, and seven consecutive days, respectively. A minimum of 48 hours of recovery should follow. These limits can probably be relaxed for intermittent exposures.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"51 4","pages":"407-423"},"PeriodicalIF":0.7,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143014859","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}

Demographic information, treatment regimens and duration, and audiometric and speech perception outcomes were recorded and analyzed.Results: 19 patients were included. The median age was 45 years. 53% were female and 21% had pre- existing rheumatologic disorders. The mean duration between hearing loss onset and physician visits was 9.6 days. All patients received an oral steroid course, while 95% also received a median of 3 intratympanic steroid injections. Patients began hyperbaric oxygen therapy an average of 34.2 days after the hearing loss onset for an average of 13 sessions. No significant relationships were found between patient comorbidities and outcomes. Of those who reported clinical improvement, 57% demonstrated complete recovery per Siegel's criteria. There was significant improvement after hyperbaric oxygen therapy for pure tone averages (50.3dB vs. 36.0dB, p<0.01) and word discrimination scores (73% vs 79%, p<0.05) for all patients regardless of reported clinical improvement.Conclusion: Hyperbaric oxygen therapy, as an adjunct to steroids, significantly improves recovery from sudden sensorineural hearing loss. The Charlson comorbidity index was not significantly associated with patient outcome, but patients with rheumatologic disorders were less likely to respond. Differentiating the natural history of the disease from hyperbaric oxygen therapy-associated improvements remains a challenge.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"51 4","pages":"393-402"},"PeriodicalIF":0.7,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143014744","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}

Few studies have compared incremental exercise to exhaustion (VO2 max testing) in a dry environment with exercise underwater. We hypothesized that the physiological effects of submersion would result in lower heart rate (HR), minute ventilation (VE), and peak oxygen uptake (VO2 peak) compared with dry conditions.Methods: Fourteen male and four female volunteers completed two VO2 peak testing sessions with approximately two hours between trials: first in the dry laboratory on a cycle ergometer and second while fully submersed in a prone position with zero static lung load. HR was monitored via ECG, and inspiratory and expiratory gas compositions were recorded using a metabolic cart. The tests were terminated once the subject reached exhaustion.Results: Absolute VO2 peak was lower in the submersed VO2 max trial (37.1 ± 7.0 mL•kg-1•min-1) compared with dry exercise (45.8 ± 8.9 mL•kg-1•min-1) p < 0.001. HR and VE were also lower in the submersed trial.Conclusions: VO2 peak while submersed is reduced relative to dry VO2 peak, which may be partly due to a decrease in heart rate and a reduction in VE.","PeriodicalId":49396,"journal":{"name":"Undersea and Hyperbaric Medicine","volume":"51 3","pages":"197-211"},"PeriodicalIF":0.7,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142330975","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}
