60세이상 노인인구를 대상으로 '농촌지역 노인들의 우울 및 인지기능 장애에 관한 연구'를 한 이정애와 정향균의 연구대상 558명에 대해 농촌지역 노인들의 인지기능 장애와 사망과의 관련성을 살펴본 결과는 다음과 같다. 1) 3년동안 동안 전체 대상자의 사망률은 558명중 57명인 10.2%이었으며 353명의 정상 인지기능군 중 사망자는 30명으로 사망률 8.5%, 126명 의 경도 인지장애군중 사망자는 14명으로 사망률 11.1%, 79명의 중증 인지장애군중 사망자는 13명으로 사망률 16.5% 이었다(표 3). 2) 3년동안 전체 연구 대상자의 생존율은 0.91이었으며 정상, 경도, 중증 인지기능 장애군의 3년 생존율은 각각 0.92, 0.90, 0.86이었다. 로그 순위 검정법으로 인지기능 정상군과 경도 및 중증의 각 인지기능 장애군의 생존곡선을 비교한 결과 통계적으로 유의하지 않았다. 또한 인지기능 정상군과 경도 이상의 인지기능 장애군간 생존곡선을 비교한 결과도 유의한 차이는 없었다. 3) 혼란변인을 보정하지 않는 Cox의 비례위험 회귀 모형의 단변량분석의 결과 95% 신뢰구간(C.I. : Confidence Interval)에서 사망위험도가 유의한 변인은 연령, 월수입, 흡연습관, 신체장애 등이었으며, 인지기능 장애정도를 정상 그리고 경도 및 중증으로 분류한 분석에서는 정상군에 비해 경도 및 중증의 사망위험도가 유의하게 높지 않았으나, 인지기능 점수(MMSEK score)의 증가에 따른 분석 결과 사망위험도가 0.94로 유의하게 낮게 나타났다(표 4). 4) 잠재적 혼란변인들의 영향을 보정한 Cox의 비례위험 회귀모형의 다변량 분석의 결과 인지기능 장애정도 및 MMSEK 점수증가에 따른 사망위험도는 어느 모형에서도 인지기능 장애정도가 사망에 미치는 위험도는 통계적으로 유의하지 않았다(표 5). 5) 남녀별로 각각 인지기능 장애와 사망위험도와의 관계를 알아보기 위해 다변량 분석을 시행한 결과 인지기능 장애정도 및 MMSEK 점수 증가에 따른 사망위험도는 어느 모형에서도 인지기능 장애정도가 사망에 미치는 위험도는 통계적으로 유의하지 않았다(표 6, 표 7). 이상 본 연구는 농촌지역 노인들에서 인지기능 장애정도가 사망에 미치는 영향을 알아보고자 하였지만, 인지기능 장애정도가 사망에 미치는 영향을 통계적으로 유의하게 고찰하지 못하였다. The purpose of this study was to examine the mortality risk associated with cognitive impairment among the rural elderly. The subjective of study was 558 of 'A Study on the Depression and Cognitive Impairment in the Rural Elderly' of Jung Ae Rhee and Hyang Gyun Jung's study(1993). Cognitive impairment and other social and health factors were assessed in 558 elderly rural community residents. For this study, a Korean version of the Mini-Mental State Examination(MMSEK) was used as a global indicator of cognitive functioning. And mortality risk factors for each cognitive impairment subgroup were identified by univariate and multivariate Cox regression analysis. At baseline 22.6% of the sample were mildly impaired and 14.2% were severely impaired. As the age increased, the cognitive function was more impaired. Sexual difference was existed in the cognitive function level. Also the variables such as smoking habits, physical disorders had the significant relationship with cognitive function impairment. Across a 3-year observation period the mortality rate was 8.5% for the cognitively unimpaired, 11.1% for the mildly impaired, and 16.5% for the severly impaired respendents. And the survival probability was .92 for the cognitively unimpaired, .90 for the mildly impaired, and .86 for the severly impaired respondents. Compared to survival curve for the cognitively unimpaired group, each survival curve for the mildly and the severely impaired group was not significantly different. When adjustments models were not made for the effects of other health and social covariates, each hazard ratio of death of mildly and severely impaired persons was not significantly different as compared with the cognitively unimpaired. But, as MMSEK score increased, significantly hazard ratio of death decreased. Employing Cox univariate proportional hazards model, statistically other significant variables were age, monthly income, smoking habits, physical disorders. Also when adjustments were made for the effects of other health and social covariates, there was no difference in hazard ratio of death between those with severe or mild impairment and unimpaired persons. And as MMSEK score increased, significantly hazard ratio of death did not decrease. Employing Cox multivariate proportional hazards model, statistically other significant variables were age, monthly income, physical disorders. Employing Cox multivariate proportional hazards model by sex, at men and women statistically significant variable was only age. For both men and women, also cognitive impairment was not a significant risk factor. Other investigators have found that cognitive impairment is a significant predictor of mortality. But we didn't find that it is a significant predictor of mortality. Even though the conclusions of our study were not related to cognitive impairment and mortality, early detection of impaired cognition and attention to associated health problems could improve the quality of life of these older adults and perhaps extend their survival.

Hemolymphangioma (also called hemorrhagic lymphatic malformation) is a benign hamartoma of blood and lymphatic vessels with a predilection for the head and neck area. A 52-year-old woman visited our clinic with multiple grouped hemorrhagic papules on her right upper eye lid and right lateral forehead with upper eyelid swelling, which appeared seven years prior to her visit. Laboratory tests including autoantibody were revealed no abnormality. Skin biopsy was done on right lateral forehead. The patient was diagnosed with acquired hemolymphangioma. She was treated with a variable-pulse 595-nm pulsed-dye laser (Vbeam; Candela Corp, Wayland, Mass) at a fluence of 10 or 11 J/cm2, 7-mm spot size with 10% overlap and pulse staking method, 3-ms pulse duration with dynamic cooling device. To our knowledge, this is the first case of acquired hemolymphangioma treated with pulse dye laser in Korean dermatological society.

The occurrence of malignant tumor in proximity to an arthroplasty prosthesis has been a matter of debate since it was first reported in 1978. Upon considering the number of orthopedic implants used, the occurrence of malignancy is rare. Especially in case of angiosarcoma, only a few cases have been reported worldwide. In this case, we report an extremely rare case of angiosarcoma arising at the site of a revision total hip arthroplasty. A 69-year-old female had received total hip replacement on her left hip due to osteoarthritis 8 months ago. Four months later, she complained pain on her operated area, X-ray showed loosening of implanted cup on her left hip. Thereafter, erythematous and purpuric papules and nodules were developed and spread around on her left hip. Through the skin biopsy she was diagnosed with angiosarcoma, and then she died of a sharp deterioration. Herein, we report a rare case of angiosarcoma occurred after total hip replacement with a review of the literature. (Ann Dermatol 33(4) 377∼381, 2021)

Backgrounds: CTD regimen has been known as an effective induction therapy in patients with newly diagnosed MM. But, there were inconsistent results for the autologous stem cell yield for transplantation. The aim of present study was to identify the influence of CTD therapy on outcome of peripheral blood stem cell (PBSC) collection. Methods: Forty-eight patients received 4 cycles of CTD therapy. Stem cells were mobilized with cyclophosphamide (3.0 g/m2) and G-CSF (10 g/kg, daily) or G-CSF alone. Patients failing to collect ≤ 4.0×106 CD34+ cells/kg received a second mobilization courses. Results: The median age at diagnosis was 56 years (range, 39-69). Median duration from start of CTD therapy to first collection was 4.6 months (range, 3.3-8.7). Forty-four patients were mobilized with cyclophosphamide following with G-CSF and 4 patients with G-CSF alone. The median day of apheresis was 3 days (range, 2-7). The response rate for CTD regimen at mobilization was 10% (5/48) of CR, 25% (12/48) of VGPR and 63% (30/48) of PR. A median number of harvested CD34+ cells was 8.6×106 cells/kg. At the first mobilization, 83% (40/48) of patients had been reached the minimal PBSC collection target of ≥ 2.0×106 CD34+ cells/kg and 71% (34/48) of patients achieved the collection ≥ 4.0 x 10^6 CD34+ cells/kg. At the end of second mobilization, 90%(43/48) of patients had yields of at least ≥ 2.0×106 CD34+ cells/kg and 77% (37/48) of patients had yields of ≥ 4.0×106 CD34+ cells/kg. During mobilization period, three patients were developed grade 3/4 non-hematologic adverse events. Conclusion: CTD regimen is an effective induction therapy in patients with newly diagnosed MM showing high response rate and acceptable rate of autologuos stem cell yield without any detrimental effect for the following stem cell collection.

<P>Wildlife crossing structures are important for increasing biodiversity of wildlife and other animals. Thus, the objective of this study was to compare the community structure of carabid beetles along environmental transects of forest edge crossing structures in fragmented forest areas. In addition, we also investigated whether there were differences in carabid beetle assemblages due to structural differences in crossing structures, i.e., overpass and underpass. A total of 3,737 carabid beetles belonging to 60 species were collected by pitfall trapping across environmental transects from June 6 to September 3, 2015. In crossing structures, environmental variables, such as soil texture, soil organic matters, and habitat structures were different from those in neighboring habitats. Abundance and species richness of carabid beetles in underpasses were significantly lower than those in neighboring habitats and overpasses. In particular, underpasses, especially those with more artificial structures in terms of soil properties and microhabitat, appeared to be less appropriate structures for movement of carabid beetles. Although less carabid beetle species were caught in crossing structures, species composition of carabid beetles were more similar to forest areas. In conclusion, efforts are needed to improve the connectivity of habitats and consider the needs of invertebrates by providing suitable microhabitats for wildlife crossing structures.</P>
