Treatment of Facial Wrinkels with Char-Free Carbon Dioxide Laser and Erbium: YAG Laser / 대한피부과학회지

BACKGROUND: Laser facial skin resurfacing has become a method of treatment for photoaging and pigmentary conditions. Although excellent results can be obtained by high-energy, pulsed carbon dioxide(CO2) laser, significant morbidity exists due to the considerable thermal damage to the skin. The Erbium: Yttrium Aluminum Garnet(Er: YAG) laser, with a wavelength of 2940 nm, is well absorbed in water. This leads to a very small zone of thermal necrosis, compared ta the CO2 laser. OBJECTIVE: The purpose of this study was to evaluate the results of the combined use of the char-free CO2 laser and the Er: YAG laser in the treatment of facial wrinkles. METHODS: Forty-six patients, aged between 30 and 68 years, with facial wrinkles, were evaulated. Two types of resurfacing laser systems were utilized in this study, a high-energy, short-pulsed CO2 laser and a Er: YAG 1aser. Wrinkle improvement was evaulated by the patients satisfaction, clinical improvement, and photographic analysis before and after the resurfacing procedure. RESULTS: Twenty-six of the 46 patients had greater than an 80% improvement, and 19 patients had a 60-80% improvement. Only one patient showed a 50% or less improvement. CONCLUSIONS: The combination of char-free CO2 laser and Er: YAG laser for facial wrinkles is a safe and effective modality for laser skin resurfacing.

Clinical Study on Skin Disorders in Aged Persons / 대한피부과학회지

This statistical analysis was made out of 2,259 clinical cases (9. 9%) of akin disorders in the aged group over 50 years of age, among from the total 22,931 cases of outpatients, from 1974 to 1978, at Department of Dermatology, Sung-Sim HospitaI. Sex difference of the patients-male, 1, 057 (46. 8%), female, 1, 202 (53. 2%)-was found statistically significant. (countinued...)

A Case of Letterer - Siwe Disease / 대한피부과학회지

Letterer-Siwe disease in an acutely onset, progressive and fatal disorder of RES, usually appears in male children, chareacterized by constitutional signs and extraos-seous lesions. This case occurred in a 18-day-old female showing hepatomegaly, hemorrhagic crusted papular eruptions on the entire body, and abdominal distension. Direct smear of scraping materials from the skin lesion showed numerous histiocytes. Hematologic and other laboratory examinatons showed no abonormalities.
