: In order to observe the antigenic fractions in saline extract of adult Paragonimus westermani, proteins in the crude extract were separated by sodium dodecyl sulfate-polyacylamide gel electrophoresis (SDS-PAGE) in reducing conditions. The separated protein fractions were transferred to nitrocellulose paper on which 20 sera from human paragonimiasis were reacted and immunoblotted. Out of 15 stained protein bands in SDS-PAGE, 7 reacted with the sera. Of 14 reacted bands, 30 kilodalton(kDa) band was the most frequently reacted (95%) and was a strong antigen. Protein bands of 23 and 46 kDa were also strong antigens. Bands of over 150 kDa, 120 kDa, 92 kDa, 86 kDa, 74 kDa, 62 kDa, 51 kDa, 32 kDa, 28 kDa, 16.5 kDa and 15.5 kDa were also reactive but their frequencies of the reaction were variable.

We report herein two cases of localized curaneous amyloidosis (LCA) associated with neurodermatitis. Both patients suffered from persistent pruritus during several years and had small brown discrete lichenoid papules or neurodermatitis like lesion. Biopsy specimen taken from lichehoid papules revealed amyloid deposition in the papillary dermis. In histologic examination of the neurodermatitis like lesion, hematoxylin eosin stain revealed only chronic eczematous changes but special stain and election microscopic examination revealed amyloid deposition in the papillary dermis. Although neurodermatitis and LCA may be able to develop concomitantly in one patient, it was suggested that neurodermatitis may transfrom into LCA.

BACKGROUND: The successful management of chronic wounds requires adequate dressing materials and methods. Nanocrystalline silver is a recently developed form of silver antimicrobial barrier dressing material which has rapid and sustained anti-bacterial activity, reduces inflammation and promotes wound healing. OBJECTIVE: This study was done to evaluate the effect of nanocrystalline silver dressing method on the treatment of chronic wounds. METHODS: Twenty three patients with chronic wounds of various etiologies were treated with nanocrytalline silver mesh dressing material (Acticoat(TM)) using an occlusive method. Dressing changes were performed every 2 to 3 days until reepithelization. RESULTS: The treatment with nanocrystalline silver was effective in 21 of 23 cases. This dressing method can significantly reduce the frequency of dressing changes, and thus it was more comfortable to both patients and doctors. CONCLUSION: Occlusive method using nanocrystalline silver is a useful dressing method for various chronic wounds, particularly in an outpatient setting.

The frequency of HLA-B27 antigen in 24 patients with psoriasis vulgaris and 11 patients with psoriatic arthritis were examined using the standard micro-lympho- cytotoxicity technique. There was a high frequency of HLA-B27 in psoriatic spondylitis with or without peripheral arthritis (83.3%) compared to controls (4.7%) and the relative risk of HLA-B27 for developing psoriatic spondylitis was 82.5% which indicates a strong association between HLA-B27 and psoriatic spondylitis in Korean populations. However, there was no stastical significance observed in the groups of patients with peripheral arthritis alone or psoriasis vulgaris in regard to the frequency of HLA-B27.

Herein we report a case of lentigo maligna that evolved into lentigo maligna melanoma. Fifteen years ago, the patient developed a pigmented lesion on the right cheek. The lesion progressed slowly, and 2 months ago, a black nodular lesion was developed in the periphery of the pigmented lesion. Histopathologic examination of the lesions revealed findings consistent with lentigo maligna and lentigo maligna melanorna. She had been performed wide excision and cheek flap for reconstruction.

BACKGROUND: Rosacea is well recognized as a chronic cutaneous disorder primarily of the convexities of the central face. Despite its apparent high incidence, the nosology of rosacea is not well established in Korea. OBJECTIVE: The purpose of this epidemiological study was to investigate the clinical manifestations of Korean rosacea patients diagnosed by the US National Rosacea Society guidelines of US. METHODS: We performed a clinical study in 90 patients with rosacea who visited the Department of Dermatology, Korea University Ansan Hospital from January 2005 to December 2006. These patients were evaluated with regard to age, sex, primary/secondary features, clinical subtypes and predisposing factors. RESULTS: The ratio of males to females was 1 : 1.3. The age distribution showed a peak incidence in the fifth decade. Primary features of rosacea were telangiectasia (70.0%), nontransient erythema (68.9%), papules and pustules (62.2%) and flushing (61.1%). The most common secondary features of rosacea were burning and stinging (62.2%). Other secondary features were dry appearance (46.7%), edema (35.6%), plaque (20.0%), phymatous changes(18.9%), ocular manifestations (17.8%) and peripheral location (2.2%). The most common subtype was erythematotelangiectatic rosacea (51.1%), followed by papulopustular rosacea (34.4%), phymatous rosacea (12.2%) and ocular rosacea (2.2%). The majority of rosacea patients revealed mild symptoms (83.3%). Predisposing or exacerbating factors of rosacea were stress (52.2%), hot baths (46.7%), alcohol (44.4%), hot weather (42.2%), sun exposure (38.9%), exercise (35.6%), cold weather (25.5%), skin-care products (23.3%), spicy foods (21.1%), indoor heat (15.6%), heated beverages (12.2%) and humidity (4.4%). CONCLUSION: In this study, the National Rosacea Society classification system applied well to Korean patients. We identified female predominance, a peak in the fifth decade and the majority of Korean rosacea patients suffering from the erythrotelangiectatic type of rosacea. Other similarities and differences to previous reports were also discussed.
