Atraumatic peroneal compartment syndrome: An uncommon entity.

Peroneus longus ruptures are less common than ruptures of the peroneus brevis muscle and are seldom described in the literature. Ankle inversion injuries causing injury to the distal end of the peroneus longus muscle resulting in lateral compartment syndrome have been documented in the literature. We are presenting an unusual case of peroneal compartment syndrome with no overt ankle injury.

Hyperbaric oxygen treatment (HBOT) in a case of traumatic chondronecrosis of the cricoid cartilage.

Cricoid chondronecrosis is a rare entity and is scarcely reported in the literature. Its prevalence is increasing in the form of chondroradionecrosis among the survivorship of head and neck carcinoma patients treated with radiotherapy. We have reported a case of cricoid chondronecroisis caused by trauma from repeated tracheostomy.

Thermal stress inside a disabled submarine.

Background: Submarine operations require strict adherence to standard operating and safety procedures and errors in judgement or accidents could lead to catastrophe and impair the submarine's ability to surface. In case of disablement of a submarine (DISSUB), the crew would have to survive inside the submarine for a variable period awaiting rescue. Microclimate and habitability of the submarine would have to be maintained and crew would have to consume emergency rations and water.

Occupational health concerns: An analysis of physical activity of submariners.

Background: Submarine crew have low physical activity by virtue of their professional requirements. Lack of space and inadequacy of regeneration capabilities render physical activity almost impossible during deployments. However, sufficient data for physical activity levels and trends are required to measure the magnitude of inactivity.

Performing CPR on a commercial diver inside the diving bell.

CPR in a diving bell is difficult. It is taught by diving companies and training institutes but has not been subjected to the tenets of evidence based medicine. The diving bell lacks space as well as a flat hard surface to lay the patient on and therefore conventional methods of administering CPR are not possible.

Hyperbaric oxygen therapy in the battlefield.

Hyperbaric oxygen therapy (HBOT) is increasingly being used in a number of areas of medical practice. It is an accepted adjunctive therapy in conditions such as burns, crush injuries, head injuries, spinal cord injuries, reconstruction surgeries, gas poisonings, radiation injuries, various anaerobic and aerobic infections that are commonly encountered in combat. It is being evaluated as a potential therapy for a variety of illnesses such as Post Traumatic Stress Disorder (PTSD) and High Altitude Cerebral Oedema (HACO) that are typically encountered in a combat scenario.

Hyperbaric oxygen and wound healing.

Hyperbaric oxygen therapy (HBOT) is the use of 100% oxygen at pressures greater than atmospheric pressure. Today several approved applications and indications exist for HBOT. HBOT has been successfully used as adjunctive therapy for wound healing.

Livedoid vasculopathy managed with hyperbaric oxygen therapy.

Livedoid vasculopathy is an uncommon condition resulting in painful lower extremity ulceration and scarring. This condition presents as purpuric macules and papules that progress to painful, irregular ulcers of the lower legs and dorsal feet. These ulcerations are often recurrent and chronic with spontaneous remissions and exacerbations that may be seasonal.
