Asian Female Hairline Surgery Using Follicular Unit Extraction

BACKGROUND: Asian female hairline surgery is unique part among hair transplantation surgerys. Most of Asian female hairline surgery had been done by single strip harvesting technique which leave noticeable linear scar. As follicualr unit extraction is introduced1, female hairline surgery can take advantage of the Follicular Unit Extraction technique;leaving no linear donor scar. There has been a belief among surgeons who are somewhat reluctant to use follicular unit extraction for female hairline surgery that the inspection of the naturally occurring curl direction of hair, which is believed one of the critical steps for appropriate operative result in Asian female hairline surgery, is impossible in follicular unit extraction. So follicular unit extraction has to be 'plan B' in respect of Asian female hairline surgery. But author thought differently about this belief. METHODS: From December 2012 to May 2013, 78 consecutive cases of female hairline surgerys were done by follicular unit extraction. The ages of patients were 18 to 57 and mean was 34.5. The cases can be categorized in 3 groups; 1) Correction of fronttemporal recession only. 2) Whole hairline correction (including fronto-temporal recession, temporal recession and lowering of the central hairline). 3) Correction of the hairline with scar by previous aesthetic surgery just like forehead lift or forehead reduction surgery. Donor hair was harvested by follicular unit extraction and preparation of donor area was done by micro-strip shave pattern, by which no short haircut window was needed. Follow up periods were 4 months to 8 months. RESULTS: Aesthetic results of the all cases were satisfactory. There were three cases which needed small session (less than 100 hairs) for relatively less survival area (all of these areas were the anterior part of hair part) and two cases of small 'moth-eaten pattern' on donor area which need no treatment or another session for aesthetic improvement. There was no lumpy graft which can be look unnatural or literal wall of plug graft in anterior part of corrected hairline. There was no linear harvesting scar, which is in-evitable in single strip harvesting, on donor area. CONCLUSIONS: Follucualr unit extraction can be versatile technique for hair restoration surgery and also hold good for Asian female hairline surgery.

Analysis of reports on orphan lung diseases in Korean children / 소아과

PURPOSE: Orphan lung diseases are defined as lung diseases with a prevalence of 1 or less in 2,000 individuals. Despite an increase in the numbers of patients with such diseases, few studies on Korean children have appeared. To obtain epidemiologic and demographic data on these diseases, we systematically reviewed reports on pediatric orphan lung diseases in Korea over the last 50 years. METHODS: We reviewed 223 articles that have appeared since 1958 on orphan lung diseases in Korean children. These articles described a total of 519 patients aged between 0 and 18 years. We classified patients by year of publication, diagnosis, geographic region, and journal. RESULTS: Of 519 patients, 401 had congenital cystic lung diseases and 66 had bronchiolitis obliterans. About 80% of patients were described in reports published in three journals, Pediatric Allergy and Respiratory Disease (Korea), the Korean Journal of Pediatrics, and the Korean Journal of Thoracic and Cardiovascular Surgery, in which papers on 157 (30.2%), 138 (26.6%), and 111 (21.4%) patients appeared, respectively. The frequency of publication of case reports has increased since 1990. Of the 519 patients, 401 (77.3%) were from Seoul/Gyeonggi-do and 72 (13.9%) from Busan/Gyeongsangnam-do. CONCLUSION: The prevalence of pediatric orphan lung disease has increased since 1990, and some provinces of Korea have a higher incidence of these diseases than do others. Studies exploring the incidence of pediatric orphan lung diseases in Korea are needed for effective disease management.
