Medical examination of divers after COVID-19 infection: a prospective, observational study using published (original and revised) guidelines for evaluation.

Introduction: The COVID-19 pandemic raised significant concerns about fitness to dive due to potential damage to the pulmonary and cardiovascular systems. Our group previously published guidelines (original and revised) for assessment of these divers. Here, we report a prospective, observational study to evaluate the utility of these guidelines.

A system-wide health sciences faculty mentor training program is associated with improved effective mentoring and institutional climate.

Introduction: Mentorship is critical for faculty success, satisfaction, and engagement. However, many faculty, particularly underrepresented racial/ethnic (UR) faculty, lack access to high-quality mentoring. In an effort to improve mentoring for all faculty, we developed and implemented a formally structured faculty mentor training program (FMTP) across UC San Diego Health Sciences, which included institutional support, mentorship training, and department/division mentorship programs.

Perinatal Carbon Monoxide Poisoning: Treatment of a 2-Hour-Old Neonate with Hyperbaric Oxygen.

A 41-year-old gravida 4 para 3 (G4P3) and 38 weeks pregnant woman presented to labor and delivery with dizziness, headache, and decreased fetal movement after 12 hours of exposure to carbon monoxide (CO) from a grill that was used inside for heat. The mother was hemodynamically stable, and her neurologic examination was intact. Her carboxyhemoglobin level, which was obtained 12 hours after removal from the CO exposure, was 7.

Diving after SARS-CoV-2 (COVID-19) infection: Fitness to dive assessment and medical guidance.

Scuba diving is a critical activity for commercial industry, military activities, research, and public safety, as well as a passion for many recreational divers. Physicians are expected to provide return-to-diving recommendations after SARS-CoV-2 (COVID-19) infection based upon the best available evidence, often drawn from experience with other, similar diseases. Scuba diving presents unique physiologic challenges to the body secondary to immersion, increased pressure and increased work of breathing.

Dermatological Progression of a Probable Box Jellyfish Sting.

This case report describes the typical features of the dermatological progression of a patient stung by a (probable) box jellyfish. The purpose is to guide clinicians and patients to an understanding of what to expect after such a sting using the clinical narrative and unique sequential photographs of the injury. With knowledgeable consultation from experienced physicians and meticulous care, this envenomation healed without the need for skin grafting.

Management of central retinal artery occlusion following successful hyperbaric oxygen therapy: case report.

Objective: This case report presents a patient with central retinal artery occlusion (CRAO) who was successfully treated with hyperbaric oxygen (HBO₂) but subsequently suffered a recurrence of his visual loss.

Methods: CRAO may be treated successfully with HBO₂ if treatment is undertaken promptly after the onset of vision loss. The goal of HBO₂ therapy is to oxygenate the ischemic inner retinal layers via diffusion from the hyperoxygenated choroidal circulation until recanalization of the central retinal artery occurs.

A "Shark Encounter": Delayed Primary Closure and Prophylactic Antibiotic Treatment of a Great White Shark Bite.

Background: Shark bites are rare but sensational injuries that are covered in the lay press but are not well described in the medical literature.

Case Report: We present the case of a 50-year-old man who sustained two deep puncture wounds to his thigh from a great white shark in the waters surrounding Isla de Guadalupe off the coast of Baja California, Mexico, during a caged SCUBA dive. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We discuss our strategy of closing the wounds in a delayed primary fashion 24 hours after injury, our antibiotic choices, and the patient's course and review marine pathogens and appropriate antibiotic coverage.

Diplopia due to mask barotrauma.

Background: Scuba diving is a very popular and safe sport. Occasionally divers will suffer an injury from barotrauma, decompression sickness or an arterial gas embolism. The history and physical examination are important when determining the etiology of the injury and its subsequent treatment.

Refractive change in response to acute hyperbaric stress in refractive surgery patients.

Purpose: To determine whether acute hyperbaric stress affects visual acuity or refractive power after keratorefractive surgery.

Setting: Clinical multiplace hyperbaric chamber and ophthalmology clinic, University of California, San Diego, California, USA.

Methods: This prospective convenience sample study included 3 groups: 3 patients who had had bilateral myopic radial keratotomy (RK); 2 who had had bilateral myopic laser in situ keratomileusis (LASIK); and 4 control subjects who had no previous corneal refractive surgery or ocular pathology but had a myopic refractive error (-1.
