We herein report a case a demodicidosis, which is extremely rare in early childhood, in a 19 month old boy. He had been admitted to the department of plastic surgery for 20 days because of burn on both legs. During admission, he hadn't had his face washed at all. He was referred to our department due to progressively appearing, multiple, pinhead sized, dry scaling, erythematous papules on the face of 13 days duration. KOH mounts from the scaly papules revealed numerous hair follicule mites. We treated him with topical application of 25% benzoy1 peroxide gel to see complete clearing of the lesions in 32 days. We think that prolonged ret.ention of sebum in the unwashed skin, such as in our case, may predispose to the poliferation of the hair follicule mites.

The forming element of High-rise building"s landmark divides with visible and invisible elements. Until now, most of the research and study of landmark has only focused on the visible element. As a result, the invisible element which includes the identity of City has gradually lost its true identity and, also brought confusion into the city. In the formation process of the City’s landmark, it is important to find out the invisible elements and the importance of each component. By adding these invisible elements, it is going to help prearranged plans for this research. The plan which considers the invisible identity of the urban area will help understand the development of the spatial structure. Also, the plan will build up an intimate relation with the city’s identity formation. The functional connection between the visible and invisible elements happens at the high-rise building’s stylobate. When you find out the invisible elements and analyze them, then here, you will figure out the city’s landmark’s relative level of contribution. Therefore, finding out the function of the element that can represent the city and combine all of these together, it will be the main achievement of the city’s essential identity.

These clinical and mycological observations were made on 898 cases of tinea facisle diagnosed by the clinical findings and KOH exsmination among the 137,197 out-patients exsmined for five years from Jaunary 1981 to December 1985 at Chilgok Catholic Skin Clinic, Taegu, Korea. Following results were obtained: 1. The annual number of patients with tinea faciale was 159(0.75% of the total outpatients) in 1981, 174(0.56%) in 1982, 181(0.67%) in 1983, 181(0.67%) in 1984,and 203 (0.83%) in 1985. 2. Of the 898 patients, male patients numbered 395 and female 503. Although the age distribution of patients was highest under age 14 in both sexes, males outnumbered females slightly before age 19 and, as age advanced, female predominance became more marked. 3. Of the 898 patients, 7Z6 organisms composed of 5 species were isolated. The species isolated were in the order of decreasing frequency, Trichophyton(T.) mentagrophytea (296,40.8%), Microsporum(M.) canis (218,30.0%), T. rubrum (189,26.0%), M. gypseam (21,2.9%), and Epidermophyton floccosum (2,0.3%). 4. M. canis was the chief cause of tinea faciale in children under 14. The infection due to T. mentagrophytes and M. canis outnumbered T, rubrum markedly in the young age group before 14, but T. rubrum predominated in the middle age group from 20 to 29. In the old age group after 40, T. mentagrophytes reappeared as a major cause of the disease. 5. T. mentagrophytes predominated in rural area and M. cania in urban area but no sexual variation was found. T. rubrum and M. gypseum prevailed slightly more in urban areas than in rural areas. 6. Eczematous annular ringworm (without central clearing) types were seen most frequently in the cases cssed by T. menagrophytes and clsssic ringworm types were seen most frequently in the cases caused by M. cania 7. Coexistent fungal infections were chiefly T. corporis in the csses of T. mentagrophytes and M. canis, but T. pedis and T. unguium in the cases of T. rubrum. 8. As a result of mating studies, 177 strsins of T. mentagrophytes proved to be Arthroderma vanbreuseghemii (51 of the + mating type and 126 of the -mating type), 12 strains of M. gypseum proved to be Nannizzia(N) incurvata (4, - and 8,-) and 4 proved to be N. gypsea (2, + and 2, - ).

The conducting current of non-uniform plasma immersed electrode consists of ion current and secondary electron emission current caused by the impinging ion current. The ion current is determined by the ion dose passing through the sheath in front of electrode and the ion distribution in front of the electrode plays an important role in the secondary electron emission. The investigation of the distributed plasma and secondary electron effect on electrode ion current was carried out as the stainless steel electrode plugged with quartz tube was immersed in the inductively coupled Ar plasma using the antenna powered by 1 kw and the density profile was measured. After that, the negative voltage was applied by 1 kV~6 kV to measure the conduction current for the analysis of ion current.

Generalized granuloma annulare is manifested by numerous, symrnetrical, shiny, normal-skin colored, discrete or confluent, papular eruption on the sunexposed areas, most.ly in females of past middle age. Up to date, a variety of therapeutic approaches have been tried with inconsistent results. Recently several agents have been reported to be inconsistent results. Recently several agents have reported to be effecti e in the treatment of genealizecl granuloma annulare. Of these, dapsone has been used with favorable respones. The fact dapsone can inhibit the lysosomal enzyme release and the mononuclear cell-rnediated rnyeloperoxidase cytotaxicity would account for its effect in granuloma annulare even in part. We observed a case of generalized granulare in a 49-year old man, who had had numerous normal-skin colored or faintly violaceous, flattopped papular eruption on the sun-exposed areas for 3 years. He was treated successfully with dapsone 100mg a day for about 22 months.

Squamous cell carcinoma of the ovary is very rare malignant tumor originating from the malignant transfomation of mature cystic teratoma, usually being reported in about 1-3% of cases. Of malignant transformation, squamous cell carcinoma is the most common type and its prognosis is poor. Because of its rarity, the clinicopathologic characteristics are not well established. We have experienced a case of squamous cell carcinoma arising in mature cystic teratoma of ovary and present it with brief review of the literature.

To survey the seroprevalence of hepatit!s B virus(HBV) in relation to serologic tests for syphilis(STS), using VDRL and TPHA test, the tests were done in the seri of 1252 institutionalized persons, who lived in Taegu Hope Village for the poor or crippled, and 1831 controls, who had the regular routine physical examination from March to May, 1987. The positive rates nf HBsAg and anti-HBs were 11.7%(146) and 27.0%(338'). compared with 6.25%(ll) and 18.4%(337) in controls, respectively. The prevalence of HBV including HBsAg and anti-HBs was higher in institutionalized persons (38,7+i) than in controls(24.6%)(p<0.0001). The positive rate of STS was higher in institutionalized persons(7.5%) than in controls(2.9%)(p<0.0001). There was a tvend for a higher rate of seropositivity in women than in men of institution- alized persons in the both diseases. The prevalence of HBV among STS-positive cases wa.s 42.6%(40) of instituti- onalized persons and 26.4%(14) of controls, but not, statistically significant, the gre,ater part of them distributing in 4th and 5th decades. The positive rates of I-tBi.Ag in institutionalized persons was 45.5%(5) of STS-positive cases and 25. 9%,'35) of STS-negative cases. No correlation was found between the serologic ma kers of HBV and VDRL titration.

목적 : 절제 불가능한 국소진행성 비소세포폐암 환자에서 paclitaxel을 이용한 화학 방사선 동시요법의 효과를 조사하기 위해 본 연구를 시행하였다. 방법 : 화학 방사선 동시요법 기간동안 paclitaxel을 매주 60㎎/㎡의 용량으로 1시간 동안 정맥으로 투여하였다. 방사선치료는 일일 1회 1.8Gy 분할량으로 주 5회 조사하였으며, 총 63Gy까지 조사하였다. 동시치료 이후 4주기의 paclitaxel/carboplatin 복합화학요법을 시행하였다. 결과 : 28명의 환자가 등록되었고, 남자가 25명, 여자가 3명이었고, 나이의 중앙값은 60세(범위: 41~73세)였다. 19명의 환자에서 계획된 화학 방사선 동시치료를 마쳤다. 완전관해는 5명, 부분관해는 15명으로 전체 관해율은 71.4%이었고, 7명의 환자에서 3도 이상의 폐렴이 발생하였는데 이 중 3명이 치료 관련 사망하였다. 중앙 생존기간은 17.5개월(95% 신뢰구간 12.5~22.5개월)이었고 무진행 생존기간의 중앙값은 8.0개월(95% 신뢰구간 4.1~11.9개월)이었다. 결론 : 국소진행성 비소세포폐암에서 paclitaxel을 포함한 화학 방사선 동시치료는 효과적이지만 폐의 부작용이 문제가 되며 환자 대상 선택과 추적에 주의를 요한다. Background : Combined modality therapy is standard treatment of unresectable, locally advanced stage III non-small cell lung cancer (NSCLC). However, the optimal chemotherapy regimen and duration of chemotherapy remain a matter of debate. We evaluated the efficacy and feasibility of concurrent chemoradiation therapy (CCRT) in patients with locally advanced NSCLC. Methods : PS 0-2 patients with histologically proven inoperable stage III NSCLC were eligible for this trial. The patients received paclitaxel (60㎎/㎡) on days 1, 8, 15, 22, 29, 36 with a concurrent radiotherapy (5days/week, 1.8Gy/day) starting day 1 with a total dose of 63 Gy. After CCRT, four cycles of consolidation chemotherapy with paclitaxel (140㎎/㎡) and carboplatin (AUC 5) was administered to patients with a partial, complete remission or stable disease. Results : Twenty eight patients with locally advanced NSCLC enrolled in this study. The median age of the patients was 60 years. Of the 28 patients, 19 received scheduled CCRT. Overall response rate was 71.4% including 5 complete responses and 15 partial responses. Grade 3 or 4 pulmonary complication was observed in 7 patients and 3 patients died of pneumonitis. The median overall survival was 17.5 months (95% CI, 12.5-22.5). The median progression free survival was 8.0 months (95% CI, 4.1-11.9). Conclusions : CCRT including paclitaxel in patients with locally advanced NSCLC led to an encouraging response rate and survival, but resulted in high incidence of severe pulmonary complication.(Korean J Med 69:379-386, 2005)
