A Statistical Study of Dermatoses in Kangwon Province, 2010~2014 / 대한피부과학회지

BACKGROUND: The prevalence of skin diseases at a university hospital may not truly indicate their prevalence in the general population; nevertheless, it is the only available source of information. OBJECTIVE: This study aimed to investigate the prevalence of common dermatoses and compare this with previous reports. METHODS: We reviewed 29,477 new outpatients who visited the department of dermatology at Wonju Severance Christian Hospital from 2010 to 2014, and statistically analyzed the findings. RESULTS: Among the 29,477 outpatients, 14,501 (49.2%) were men and 14,976 (50.8%) were women. More patients were in their sixth decade (17.1%) or over 70 years (15.4%), in their seventh decade (13.5%) or in their fifth decade (13.0%), comprising 59% of the total outpatients. The 20 most common dermatoses were found to be urticaria, dermatophytosis, allergic contact dermatitis, other types of eczema, atopic dermatitis, pruritus, verruca, herpes zoster, alopecia, psoriasis, seborrheic dermatitis, drug eruptions, folliculitis, rosacea, benign epidermal tumor, melanocyte nevus, vitiligo, scabies, herpes simplex virus infection, and bacterial infection. In the distribution of dermatoses as disease groups, viral disease (11.2%), atopic dermatitis and eczema (10.7%); contact dermatitis and drug eruption (10.3%); erythema and urticaria (8.4%); fungal disease (7.6%); skin appendage disease (6.9%); seborrheic dermatitis, psoriasis, and pustular dermatoses (5.5%); epidermal nevi, neoplasms, and cysts (4.8%); pruritus and neurocutaneous dermatoses (4.6%); and acne (3.8%) constituted 73.8% of the total. CONCLUSION: Compared to the previous studies in the same area, the distribution of skin diseases was similar. The increasing tendency of older individuals with diseases in Gangwon province has persisted since 2000.

A Clinical Observation of Cutaneous Malignant Tumors and Premalignant Lesions in Gangwon Province over 10 Years (1999~2008) / 대한피부과학회지

BACKGROUND: The incidence of cutaneous malignant tumors and premalignant lesions has recently increased according to extended life span, social and medical environment changes. However, a few clinical data have been reported on the survey of cutaneous malignant tumors and premalignant lesions in Gangwon province. OBJECTIVE: To investigate the incidence and clinical patterns of cutaneous malignant tumors and premalignant lesions in Gangwon province. METHODS: We reviewed 485 cases of cutaneous malignant tumors and premalignant lesions from January 1999 to December 2008, at the Department of Dermatology at Wonju Christian Hospital. RESULTS: The average annual incidence of cutaneous malignant tumors among the total number of outpatients was 0.51% and that of premalignant lesions was 0.48%. Both incidences tended to increase with time in 10 year intervals. The most common cutaneous malignant tumor was basal cell carcinoma (47.98%), followed by squamous cell carcinoma (24.19%), extramammary paget's disease (7.26%), metastatic cancer (5.65%), malignant melanoma (4.44%), and lastly, lymphoma (4.44%). Among premalignant lesions, actinic keratosis (74.68%) and Bowen's disease (25.32%) were common. The mean age of onset was 67.53 years in cutaneous malignant tumors and 70.51 years in premalignant lesioins. The most common site for both, the cutaneous malignant tumors and premalignant tumors, was the face (63.97% and 81.43%, respectively). The ratio of men to women was 1.11:1 in cutaneous malignant tumors and 1:2.48 in premalignant lesions. CONCLUSION: The incidence of cutaneous malignant tumors and premalignant lesions has gradually increased in Gangwon province. This data will be made available for the study about the association of cutaneous malignant tumors and premalignant lesions.

Human Papillomavirus Prevalence in Gangwon Province Using Reverse Blot Hybridization Assay

BACKGROUND: Human papillomavirus (HPV) plays an important role in the development of cervical carcinoma. Although there is a general agreement that high levels of HPV are related to cervical cancer, the prevalence and distribution of HPV genotypes seems to vary by geographical region. This study was designed to investigate the prevalence of HPV genotypes in Gangwon Province, Korea. METHODS: In total, 342 samples were examined by Pap smear and HPV-ID(R) reverse blot hybridization assay (REBA) (M&D, Wonju, Korea). RESULTS: Overall HPV positivity was 80.9% and 64.4% in women with abnormal and normal cytology by REBA, respectively. The five most common HPV types were: HPV 16, 53, 58, 56, and 33 in samples with abnormal cytology, and HPV 16, 53, 58, 70, and 18 in samples with normal cytology. CONCLUSIONS: The REBA can provide useful data regarding prevalence of HPV genotypes. Gangwon Province showed high prevalence of HPV infection in women. The most common HPV type in Gangwon Province was HPV16, and HPV 53, 58, 56, 70 were frequently present.

A Statistical Study of Dermatoses in Wonju (2005~2009) / 대한피부과학회지

BACKGROUND: While the incidence of skin diseases in our university hospital may not indicate their true incidence in the population, it nonetheless represents the only available source of information. Recently, the composition of the Wonju population has changed rapidly in that the population of old people is increasing and urbanization is accelerating. Thus, statistical study of the latest data is necessary. OBJECTIVE: To study the prevalence of common dermatoses and compare this with previous reports. METHODS: We reviewed 27,718 new outpatients who visited the department of dermatology at Wonju Christian Hospital from 2005 to 2009, and statistically analyzed the findings. RESULTS: The study results are summarized as follows: Of the 27,718 outpatients, the total number of male patients was 14,190 (51.2%), and the numbers of female patients was 13,528 (48.8%). The most frequent age groups were the fifth decade (15.9%), sixth decade (13.9%), seventh decade (13.2%), and fourth decade (12.5). The 20 most common dermatoses were dermatophytosis, urticaria, atopic dermatitis, allergic contact dermatitis, other eczema, verruca, alopecia, herpes zoster, pruritus, psoriasis, drug eruption, vitiligo, acne, seborrheic dermatitis, folliculitis, benign epidermal tumors, nevocellular nevus, irritant contact dermatitis, bacterial diseases, and rosacea. The dermatoses which revealed a decreasing tendency to be treated by medicine included dermatophytosis, atopic dermatitis, other eczema, pruritus, psoriasis, drug eruption, vitiligo, acne, and irritant contact dermatitis. An increasing tendency was noted in urticaria, allergic contact dermatitis, verruca, alopecia, herpes zoster, seborrheic dermatitis, folliculitis, benign epidermal tumor and nevocellular nevus. Diseases with high seasonal distribution in summer were dermatophytosis, herpes zoster, vitiligo, folliculitis, irritant contact dermatitis and bacterial infections. However, atopic dermatitis, pruritus, and psoriasis showed high incidence in the winter period. Verruca, acne and nevocellular nevus had a peak incidence in both summer and winter. CONCLUSION: The distinct characteristic of skin diseases of the Gangwon province was a high incidence of pruritus and seborrheic dermatitis which represent the senile diseases.
