Hyperbaric Oxygen for a Thalassaemic Leg Ulcer

Hyperbaric oxygen for a thalassaemic leg ulcer.

A thalassaemic ulcer in a male Greek Cypriot patient, resistant to standard medical treatment, was treated using hyperbaric oxygen in a recompression chamber. The patient breathed 100% oxygen by face mask whilst the chamber was compressed with air to a pressure of 2.5 atmospheres absolute. The ulcer became fully epithelialised within three weeks of starting treatment.

Hydroxyurea associated leg ulcer succesfully treated with hyperbaric oxygen in a diabetic patient.

Oxygen tension in healing tissues is heterogeneous. Increased oxygen mostly stimulates repair mechanisms and enhances tissue healing. Hyperbaric oxygen therapy increases blood and tissue oxygen content and may help maintain cellular integrity and function. Hydroxyurea (HU) is a cytotoxic agent, which leads to inactivation of ribonucleotide reductase, inhibition of cellular DNA synthesis, and ce...

The treatment of varicose leg ulcers by hyperbaric oxygen.

Hyperbaric oxygen at 2 atmospheres pressure was administered to nineteen cases of chronic varicose leg ulceration. Treatment was given for 2 hr on 5 days of each week. Bacterial infection of the ulcers was suppressed, and drying of the lesions occurred within hours of commencing treatment. Epithelialization of healthy granulation tissue was a constant feature. Simple venous ulcers consistently ...

A Hydroxyurea-induced Leg Ulcer.

Hydroxyurea is a cytostatic agent that has recently become the drug of choice in the treatment of various myeloproliferative diseases. The cutaneous side effects of hydroxyurea include xerosis, hyperpigmentation, nail discoloration, and scaling. Leg ulcers have only rarely been reported in association with hydroxyurea treatment. A 75-year-old woman presented with leg ulcers, nail discoloration,...
