BACKGROUND: Disinfection is essential for the prevention of hospital infection. HICLO-S (Soosan environment Co., Yongin, Korea), one of the electrolyzed oxidized water was recently developed as a disinfectant. This is not costly and does not cause any clinical problems and environmental pollution. We evaluated the disinfective activity of HICLO-S against several clinical isolates of bacteria and yeasts. METHODS: 25 strains of bacteria and two strains of yeast were exposed to HICLO-S (30 & 50 ppm HICLO-S) disinfectant for the various periods (0.5, 1, 2, 4, 8, 10, 15, 20 minutes). After the exposure to HICLO-S disinfectant, 0.01 mL of mixture of microorganisms and HICLO-S was inoculated into brain-heart infusion broth or onto Sabouraud dextrose agar and incubated at 35degrees C for 48hours. RESULTS: All strains of bacteria and yeast were killed within 30 seconds after an exposure to 30 ppm of HICLO-S. All of three strains of spore forming Bacillus subtilis were killed within 4 minutes after an exposure to 30ppm of HICLO-S, but all of three strains were killed within 30 seconds in 50 ppm of HICLO-S. CONCLUSIONS: This study showed that HICLO-S disinfectant was effective for the disinfection of commonly isolated bacteria and yeast from hospital, but less effective against spore-forming bacteria. It may be recommended that HICLO-S should he used for the effective disinfection of skin, instruments and hospital floors.

BACKGROUND: The risk of rubella infection is higher among hospital employees than others because of more exposure to rubella viruses. Because rubella infection during pregnancy can cause congenital rubella syndrome, special preventive measures should be taken for female employees in the hospital. METHODS: 309 employees in Soonchunhyang Kumi Hospital, aged from 18 to 45 years old, were included this study. Rubella IgG antibody was detected by the method of MEIA (microparticle enzyme immunoassay). And non-immunized employees were received by Wister RA 27/3 rubella vaccination and rechecked rubella antibody titers at 2 months later after vaccination. RESULTS: Among 309 subjects, 276(89.3%) were positive for rubella IgG antibody. The overall mean titer of rubella antibody was 72 IU/mL (SD: 67 IU/mL). The rubella antibody in titer decreased gradually with aging. The seroconversion rate after vaccination was 100%(28/28). CONCLUSIONS: The authors recommend that the employees susceptible to rubella or all employees in the hospital should be vaccinated for preventing rubella.

Positron emission tomography (PET) with 2-[F-18]-Fluoro-2-deoxy-D-glucose (FDG) was performed in ninteen patients who had benign musculoskeletal tumors in order to determine if there was a relationship between histologic grade of tumor and FDG uptake of tumor. These patients had been evaluated previously with computed tomography (CT) or magnetic resonance (MR) imaging or both. The diagnoses were confirmed with incisional or excisional biopsy or by radiographic follow-up. Generally high-grade tumors had significantly greater uptake of FDG than low-grade lesions . Benign lesions such as giant cell tumor, fibrous dysplasia, and osteofibrous dysplasia showed significant elevation of SUV (Standardized Uptake Value) above 4.0. On the contrary. The current studies suggest the utility of FDG-PET imaging as an adjunct to CT or MR imaging in the evaluation of benign tumors. And results of PET suggest benign tumors with high SUV are histologically active lesion and tend to be locally aggressive.

BACKGROUND: Alopecia areata is replete with data from studies using variuos therapeutic approaches, none of which is clearly superior to another. OBJECTIVE: This study was designed to evaluate the therapeutic effect of cryotherapy in alopecia areata. METHODS: Thirty three patents with AA(M:13, F:20) well conduted in this study, precluding 3 patients with the moderate and extensive lesions. Cryotherapy using a cotton swab dipped with liquid nitrogen was applied to the involved areas, repeated with 2 times of freeze thaw cycle of two seconds. In 13 cases of AA multiplex, the lesions were divided into two groups, each of which was undertaken cryotherapy and intralesional injection of triamcinolone(3mg/ml) for evaluation of their respeetive effects. The treatment was done weekly method of 1 to 11 times, Th therapeutic response was determined as the regrowth of terminal hairs on the treated area(s) at 12 Weeks. RESULTS: Of the 33 patients with AA, the overall responders were 22(66.7%). There seemed good response rates of 70.0 % in females, 71.4 % in AA multiplex and 72.2 % in third decade as well as 72.4 % in those with lower than 1 year of duration. The remarkable resionse had 3-4 times in treatment numbers. There were no untoward side effects in patients except mild erythema. In the 13 patients treated with both modalities, cryotherapy had a slightly higher esaonse than triamcinolone therapy (69.2% vs 61.5%, p>0.05 by x-test). CONCLUSION: The effect of cryotherapy therapy in AA patients is not less than the intralesional therapy of triamcinolone. In addition, cryotherapy may be recommendec as the new, safe therapeutic modality.

Quality control survey was done on the plasma triglyceride determination of six laboratories and following results were obtained. 1) Coefficients of variation were less than 5% in 3 laboratories and over 10% in one laboratory. 2) High interlaboratory variation was inferred from the mean values ranging from 104.0~136. 4mg% (sample A) with enzyme method and 44.7~65.3 (Sample B) with acetylaceton method. 3) Establishment of normal plasma triglyceride level in Koreans and supervised quality control by the authority seemed to be urgent.

We report a rare case of sporadic keratosis punctata palmaris et plantaris in a 49-year-old woman. Thirty years ago, firm semitranslucent papules developed on the middle portion of her palms without any subjective symptom. The lesions had flat-topped smooth surfaces. They were concentrated along the margins of the hands, especially on the lateral surfaces of both index fingers and finger tips/ Ten years ago, similar hyperkeratotic papules with or without central craters developed on the weight bearing portions of her soles. Her family and past histories were negative. The biopsy specimen revealed a dense hyperderatotic stratum corneum which fitted into a cup shaped depression in the stratum malpighii and a turning inward of the rete ridges at the margin. The Masson trichrome and elastic strains showed no peicific dermal changes.
