Cutis marmorata in decompression sickness is associated with a patent foramen ovale.

A 39-year-old male commercial diver developed cutis marmorata after a dive. He had a full recovery after therapy in a hyperbaric oxygen chamber. Transthoracic echocardiography revealed an atrial septal aneurysm and a large shunt during normal respirations. This form of decompression sickness may progress to type II DCS, thus is important to identify and treat. Cutis marmorata as a result of diving is highly associated with an atrial septal defect or a large patent foramen ovale. It is particularly important to assess these patients for a right-to-left shunt as part of a medical evaluation prior to returning to diving.

Successful treatment of facial vascular skin diseases with a 577-nm pro-yellow laser.

BACKGROUND: Treatment of vascular skin diseases is one of the most important indications of the laser. AIMS: To evaluate the effectiveness of 577-nm pro-yellow laser in the treatment of some vascular skin diseases. PATIENTS/METHODS: Ninety-five patients with vascular skin diseases were included in this prospective monocentric study. They were classified into: port-wine stain birthmarks (n = 37), papulopustular rosacea (n = 20), facial telangiectasia (n = 16), and facial erythema (n = 22). All participants received a monthly session of 577-nm pro-yellow laser. Follow-up was done by comparing the photographs before and at every follow-up visit. RESULTS: At the final visit, there was a significant improvement (>50%) occurred in 24/37 (64.82%), 12/20 (60%), 10/16 (62.5%), and 19/22 (86.3%) cases and poor response occurred in 6/37 (16.2%), 2/20 (10%), 2/16 (12.5%), and 0/22 cases after a mean number of sessions 7.76 ± 2.28, 3.1 ± 1.8, 3.63 ± 1.12, and 1.8 ± 0.85 in port-wine stain, rosacea-, facial telangiectasia-, and facial erythema-treated groups, respectively. Transient irritation and erythema during the session were the only complications reported in the study. CONCLUSION: Facial port-wine stains, rosacea, telangiectasia, and erythema can be successfully treated with a single pass of 577-nm pro-yellow laser with a minimal side effect. Facial erythema showed the highest degree of success with the least number of sessions, while more sessions needed for the treatment of port-wine stain.
