Clinical Characteristics of Cholinergic Urticaria in Korea

BACKGROUND: Cholinergic urticaria is a type of physical urticaria characterized by heat-associated wheals. Several reports are available about cholinergic urticaria; however, the clinical manifestations and pathogenesis are incompletely understood. OBJECTIVE: The purpose of this study was to investigate the clinical characteristics of cholinergic urticaria in Korea. METHODS: We performed a retrospective study of 92 patients with cholinergic urticaria who were contacted by phone and whose diagnoses were confirmed by the exercise provocation test among those who had visited The Catholic University of Korea, Catholic Medical Center from January 2001 to November 2010. RESULTS: All 92 patients were male, and their average age was 27.8 years (range, 17~51 years). Most of the patients had onset of the disease in their 20s and 30s. Non-follicular wheals were located on the trunk and upper extremities of many patients, and the symptoms were aggravated by exercise. Eight patients showed general urticaria symptoms and 15 had accompanying atopic disease. Forty-three patients complained of seasonal aggravation. Most patients were treated with first and second-generation antihistamines. CONCLUSION: Dermatologists should consider these characteristics in patients with cholinergic urticaria. Further investigation and follow-up studies are necessary to better understand the epidemiological and clinical findings of cholinergic urticaria.

A Statistical Survey of Nail Disease: Nail Clinic of the Yeouido Saint Mary's Hospital, 2000~2010 / 대한피부과학회지

BACKGROUND: Nail diseases reflect systemic diseases or other dermatologic diseases and also have many kinds of primary diseases on the nail apparatus itself. Recently, the proportion of the nail disorder is steadily increasing among many dermatologic diseases. Although there have been many studies about nail disorders, there have been no studies on the long-term observation of nail disorder in Korea. OBJECTIVE: The purpose of this study was to analyze recent changes in the incidence of nail disorders and compare the incidence with previously reported data. METHODS: We retrospectively reviewed the medical records of 3,384 patients with nail disorders who visited Yeouido Saint Mary's Hospital during the last 11 years (2000~2010). RESULTS: There were 1,504 patients with onycomycosis (44%) among 3,384 patients with nail disorders. Among 1,504 patients, 809 were male and 695 were female and the ratio of men to women was 1:0.86. There were 1,880 patients with various nail diseases except onychomycosis; infectious or inflammatory disease (10.1%), traumatic nail disorder (7.1%), nail involvement in dermatological disease (5.7%), pigmentary disorder (3.4%), nail tumor (3.3%), nail involvement in systemic disease (2.1%), medication-induced nail disorder (0.6%), congenital disease (0.3%), other nail disease (23.1%) including twenty-nail dystrophy (3.2%). CONCLUSION: Most results were compatible with those of other previous studies, but the ratio of onycomycosis to total nail disorder was slightly decreased, and patients with drug induced nail disease, nail tumor and twenty-nail dystrophy increased slightly. Due to increasing average life expectancy and improvements in the quality of life, patients with nail disease that visit the hospital are increasing constantly. To correspond with this tendency, more concern, and prospective and large-scale study are necessary.
