ABSTRACT
BACKGROUND: The coronavirus disease 2019 pandemic has resulted in a growing population of individuals who experience a wide range of persistent symptoms referred to as "long COVID." Symptoms include neurocognitive impairment and fatigue. Two potential mechanisms could be responsible for these long-term unremitting symptoms: hypercoagulability, which increases the risk of blood vessel occlusion, and an uncontrolled continuous inflammatory response. Currently, no known treatment is available for long COVID. One of the options to reverse hypoxia, reduce neuroinflammation, and induce neuroplasticity is hyperbaric oxygen therapy. In this article, we present the first case report of a previously healthy athletic individual who suffered from long COVID syndrome treated successfully with hyperbaric oxygen therapy. CASE PRESENTATION: A previously healthy 55-year-old Caucasian man presented 3 months after severe coronavirus disease 2019 infection with long COVID syndrome. His symptoms included a decline in memory, multitasking abilities, energy, breathing, and physical fitness. After evaluation that included brain perfusion magnetic resonance imaging, diffusion tensor imaging, computerized cognitive tests, and cardiopulmonary test, he was treated with hyperbaric oxygen therapy. Each session included exposure to 90 minutes of 100% oxygen at 2 atmosphere absolute pressure with 5-minute air breaks every 20 minutes for 60 sessions, 5 days per week. Evaluation after completing the treatment showed significant improvements in brain perfusion and microstructure by magnetic resonance imaging and significant improvement in memory with the most dominant effect being on nonverbal memory, executive functions, attention, information procession speed, cognitive flexibility, and multitasking. The improved cognitive functions correlated with the increased cerebral blood flow in brain regions as measured by perfusion magnetic resonance imaging. With regard to physical capacity, there was a 34% increase in the maximum rate of oxygen consumed during exercise and a 44% improvement in forced vital capacity. The improved physical measurements correlated with the regain of his pre-COVID physical capacity. CONCLUSIONS: We report the first case of successfully treated long COVID symptoms with hyperbaric oxygen therapy with improvements in cognition and cardiopulmonary function. The beneficial effects of hyperbaric oxygen shed additional light on the pathophysiology of long COVID. As this is a single case report, further prospective randomized control studies are needed.

Ischemic complications of glans penis following circumcision are rare, and if occurs can culminate in irreversible necrosis with severe long-term consequences. Here we present 2 challenging cases of neonates suffering from acute severe glans penis ischemia after circumcision that were treated by hyperbaric oxygen treatment (HBOT). In addition to case presentations, the literature related to complications of circumcision and the physiological effects of HBOT are being reviewed. Based on the review and the case presented, we conclude that HBOT can be used as salvage treatment for circumcision induced glans ischemia as early as possible before full necrosis develops.

INTRODUCTION: Radiation therapy is an acceptable treatment for several types of malignancies. Despite advances in technology, the adverse effects of radiation therapy are still common. Tissue radio necrosis/post radiation necrosis is a frequent adverse event occurring in 5-15% of the patients undergoing radiation therapy. Radiation therapy damages the healthy tissue that surrounds the radiation zone, and thereby, can cause anguish to the patients. The phenomenon is a challenging one, since current treatments offered to the patients that suffer from post radiation injury have limited efficacy. The current paper will discuss 2 cases: 1) A 53 year old woman who suffered from supraglottic laryngeal carcinoma, and underwent hemi-laryngectomy with combined chemo and radiation therapy to the neck; and 2) a 72 year old male with prostate cancer who received hormonal and radiation therapy to the pelvis. Both patients suffered from post-radiation injury and were successfully treated with hyperbaric oxygen that led to a full recovery, both clinically and objectively. A treatment protocol of 2 ATM 100% hyperbaric oxygen for 5 days a week for a total of 60 sessions has been shown to help resolve radiation-induced damage.
