배경 : Clostridium difficile에 의한 설사(Clostridium difficile associated diarrhea; CDAD)는 임상 경과가 다양하다. 최근에 유럽과 북미에서 C. difficile 감염의 발생률이 증가하고 고전적 치료에 잘 반응하지 않으며 이환률이 증가하였고, 이러한 원인이 새로운 균주의 탄생에 기인한다고 보고되었다. CDAD의 예후에 영향을 미치는 세균성 요인과 숙주 요인을 확인하기 위해 본 연구를 진행하였다. 재료 및 방법 : 2002년 8월부터 2003년 12월까지 CDAD가 진단된 20세 이상인 환자들을 대상으로 후향적 Cohort 연구를 하였다. 세균성 요인을 확인하기 위해 cdt A, cdtB, tcd A, tcd A rep 그리고 tcd B 유전자(binary toxin)를 확인하였다. 설사가 치료 시작 후 11일 이상 지속되거나, 2달 이내에 재발하거나, 수술 혹은 다른 시술이 필요한 경우, 사망한 경우 예후가 좋지 않은 것으로 정의하였다. 결과 : 총 115예에서 toxin을 생성하는 C. difficile가 동정되었으며, Toxin A와 toxin B 모두 양성인 균이 91예, toxin B만 양성인 균이 24예였다. Toxin A 생성 여부가 예후에 영향을 미치지 않았지만, 제산제를 사용한 환자에서 그렇지 않은 환자에 비해 toxin B만 양성인 균이 많이 동정되었다(P<0.05). 예후가 좋지 않은 경우는 39예(33.9%)였고 76예(66.1%)에서 예후는 양호하였다. 단변량 분석에서 70세 이상의 고령, 남성, 증상 발현 후 사용한 항생제의 개수 사용, 증상 발현 후 carbapenem, aminoglycoside, glycopeptide 사용, 당뇨 및 뇌졸중 병력이 있는 경우, 그리고 높은 Charlson index가 불량한 예후 인자로 확인되었다. 그러나 독립적인 예후 인자를 조사했을 때에는70세 이상의 고령(odds ratio=3.378, P=0.009), 증상 발현후 carbapenem 사용(odds ratio 7.210, P<0.001)이 예후에 중요한 영향을 미치는 요소로 확인되었다. 결론 : 70세 이상의 고령과 증상 발현 후 carbapenem 사용이 CDAD 독립적인 불량한 예후인자이다. Background : Clostridium difficile associated diarrhea (CDAD) has a wide range of clinical manifestations. The prognostic factors of CDAD are not fully understood. Materialsand Methods : A retrospective cohort study of 115 patients with CDAD from Aug. 2002 to Dec. 2003 was conducted to evaluate prognostic factors of CDAD. Bacteriologic factors were determined by detecting the binary toxin gene, tcd A, tcd A rep and tcd B gene. Poor prognosis was defined as diarrhea more than 10 days even with classic treatment, recurrence, death, and moribund discharge. Results : Approximately 79% of isolated strains were toxin A+/B+ strains and 21% were toxin A-/B+ strains. There was no difference in prognosis between toxin A+ and toxin A- strains. 39 (33.9%) cases showed poor prognosis and 76 (66.1%) cases showed good prognosis. Univariate analyses revealed that the poor prognostic factors were old age over 70 years old, male, the number of antibiotics used after onset of symptom, the administration of carbapenems, aminoglycosides, glycopeptides after onset of symptom, history of DM and stroke, and high Charlson comorbidity index. Multiple logistic regression analysis identified old age over 70 years old (odds ratio=3.378, P=0.009) and the administration of carbapenems after onset of symptom (odds ratio 7.210, P<0.001) as the independent poor prognostic factors. Conclusion : Old age over 70 and the administration of carbapenems after onset of symptom were the poor prognostic factors for CDAD caused by none-binary toxin producing strains.

Pretibial myxedema(PM) is a dermatological manifestation of Graves` disease, which commonly presents as diffuse, non-pitting edema of shins and less often as plaques, nodules, or elephantiasis lesions mimicking lymphedema. Most common site is pretibial area and localized thickening of the pretibial skin causes deposition of acid mucopolysaccharides. There are 7 cases of pretibial myxedema reported in domestic dermatology literature. The only four of cases occurred after treatment of hyperthyroidism like that our case. Herein, we report a case of pretibial myxedema with Grave`s disease and Grave`s ophthalmopathy. A 51-year-old male visited our department with multiple erythematous patches and nodules on Lt. pretibial area. He had been diagnosed with Grave`s disease 6 months ago and Grave`s ophthalmopathy 3 months ago. The incisional biopsy on Lt. pretibial area showed mucinosis in dermis with perivascular lymphocytic infiltration. The lesions improved after steroid intralesional injection. For persisted local lesions despite improvement of systemic symptoms, we propose that the steroid intralesional injection may be an alternative to treatment.

[P336] Generalized cutaneous angiosarcoma associated with multiple myeloma

( Jeong Won Jo ),( Young Bin Shin ),( Hae Bong Jeong ),( Yun Sun Moon ),( Do Seon Jeong ),( Eui Chang Jung ),( Chi Yeon Kim ),( Tae Jin Yoon ) 대한피부과학회 2017 대한피부과학회 학술발표대회집 Vol.69 No.1

Cutaneous angiosarcoma is a rare, malignant, vascular neoplasm of the skin commonly diagnosed in the head and neck regions. It arises infrequently in the lower extremity. In most cases, the exact etiology of cutaneous angiosarcoma is unclear. Recently, gene amplifications, especially MYC gene, have been identified as a new etiopathogenesis of angiosarcoma. MYC amplification may induce aberrant angiogenic phenotypes allowing the onset of the malignancy. Meanwhile, in multiple myeloma, MYC is activated and contributes to the malignant phenotype. Therefore, there is a possibility that MYC gene might be the common cause of angiosarcoma and multiple myeloma. Herein, we present the rare case of cutaneous angiosarcoma on lower extremity accompanied by multiple myeloma. An 85-year-old woman visited our department with multiple brownish to black colored nodules with hyperkeratotic crust, which were 0.3 to 0.8 cm in diameter, on the both feet and toes. The excisional biopsy was performed and a diagnosis of cutaneous angiosarcoma was made. At the time of visit, anemia, azotemia, proteinuria and hematuria were found. Immunofixation electrophoresis and bone marrow were performed, so multiple myeloma was diagnosed. We suspected carefully that MYC gene might be the common cause of angiosarcoma and multiple myeloma.

Background: Based on the reports of low prevalence and severity of pediatric severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, the Korean government has released new SARS-CoV-2 infection response and treatment guidelines for children under the age of 12 years. The government has further directed school reopening under strict preventive measures. However, there is still considerable concern on the impact of school reopening on community transmission of Coronavirus disease 2019 (COVID-19). In the present study, we aimed to evaluate the appropriateness of these directives and the severity of SARS-CoV-2 infections in children as compared to adults using sufficient national sample data. Methods: In the present study, we evaluated the severity of SARS-CoV-2 infection in pediatric patients as compared to adults by analyzing the length of hospital stays (LOS), medical expenses, and hospital and intensive care unit (ICU) admission rates. A multivariate linear regression analysis was carried out to examine the effects of COVID-19 patients that the characteristics on the LOS and medical expenses, and multivariate logistic regression analysis were performed to identify COVID-19 characteristics that affect hospital and ICU admission rates and to prove the low SARS-CoV-2 infection severity in pediatric patients. Results: The hospitalization period for children aged 0–9 was 37% shorter and that of patients aged 10–19 years was 31% shorter than those of older age groups (P < 0.001). The analysis of the medical expenses by age showed that on average, medical expenses for children were approximately 4,900 USD lower for children than for patients over 80 years of age. The linear regression analysis also showed that patients who were 0–9 years old spent 87% and those aged 10–19 118% less on medical expenses than those aged 70 and over, even after the correction of other variables (P < 0.001). The probability of hospitalization was the lowest at 10–19 years old (odds ratio [OR], 0.05; 95% confidence interval [CI], 0.03–0.09), and their ICU admission rate was also the lowest at 0.14 (OR, 0.14; 95% CI, 0.08–0.24). On the other hand, the likelihood of hospitalization and ICU admission was the highest in children aged 0–9 years, and among patients under the age of 50 years in general. Conclusion: This study demonstrated the low severity of SARS-CoV-2 infection in younger patients (0–19 years) by analyzing the LOS, medical expenses, hospital, and intensive care unit admission rates as outcome variables. As the possibility to develop severe infection of coronavirus at the age of 10–19 was the lowest, a mitigation policy is also required for middle and high school students. In addition, children with underlying diseases need to be protected from high-risk infection environments.

But there has not been any report on the clinical characteristics of herpes zoster in the Province of Gyeongsangnam-do. Objectives: The purpose of this study was the elucidation of the clinical characteristics of herpes zoster in the Province of Gyeongsangnam-do. Methods: The study was conducted between 2011 and 2015 at our hospital outpatients. 901 patients with herpes zoster were evaluated in regard to age, sex, dermatomic distributions, associated diseases and complications. Results: Out of 901 cases, 396 were males and 505 were females. The maximum incidence was in the over 70 year-old group (26.4%). The most frequent involved dermatome was the trigeminal dermatome (28.7%). Associated diseases were observed in 679 patients (75.3%), which included hypertension (21.2%), malignancy (11.4%) and so on. Out of 901 patients, 443 (49.2%) developed complications. The most common complication was postherpetic neuralgia (27.1%). It is noteworthy that skin edema was accompanied from 43 patients (4.8%). Fourty patients showed edematous change on herpes zoster lesion. But other 3 patients showed facial edema in spite of involving herpes zoster in other area. Conclusion: Most of the results are similar to those previously reported, except for a higher incidence in trigeminal dermatome. The most interesting part of this study is herpes zoster can cause skin edema. We need to take further studies in future by others to explain causes in detail.

A caes of eruptive lichen planus

( Jeong Won Jo ),( Hae Bong Jeong ),( Yun Sun Moon ),( Do Seon Jeong ),( Eui Chang Jung ),( Chi Yeon Kim ),( Tae Jin Yoon ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.1

Eruptive lichen planus is a rare variant of lichen planus and variety of rapidly spreading and extensive form of lichen planus. Lichen planus is a common and chronic inflammatory disease of the skin and mucous membranes. It typically manifests as pruritic, faintly erythematous to violaceous, flat-topped, polygonal papules distributed mainly over the flexural areas of wrists, arms, and legs. It usually resolves after a variable period of time, ranging from a few months to years, leaving behind pigmentation and/or scarring. The exact pathogenesis of lichen planus is not clear. Association of a chronic active hepatitis C virus infection with lichen planus and triggering of lichen planus following a hepatitis B virus vaccination has been previously described. So we report the eruptive lichen planus in patients who have received treatment with hepatitis B infection.
