Objectives: Late-onset schizophrenia (LOS, age at first onset ≥40 years) is characterized by including predominance of women, better premorbid social adjustment and lower severity of positive/negative symptoms. However, few studies have been conducted on LOS, especially in Asian countries. This study aimed to examine the clinical features of LOS in comparison with early-onset schizophrenia (EOS). Methods: By retrospectively reviewing medical records, we assessed demographic data and clinical features of 76 LOS (20 males) and 357 EOS (144 males) who admitted to the psychiatric ward of a general hospital. Results: The mean ages of onset were 47.3±5.1 (LOS) and 25.7±6.5 (EOS) years. There were significantly more women in LOS (73.7%) than EOS (59.6%). Significantly more LOS patients had a marital (88.2% vs. 25.8%) and employment history (28.9% vs. 13.1%) than EOS. Patients with LOS had fewer negative (14.3±9.0 vs. 19.9±9.3), general psychopathology score (36.9±11.1 vs. 42.3±13.9) than EOS patients. Conclusion: In line with previous studies, this study demonstrated that LOS patients have better premorbid social adjustment. Our finding also replicates previous findings that LOS patients differ from EOS in predominance of women and relative lack of negative symptoms. These results suggest that LOS may be a distinct subtype of schizophrenia.

Along with the well-established evidence on the negative effect of social isolation on physical mental health and mortality, increasing attention has been paid to multi-dimensional nature of social isolation. In this study, the main effect and interaction effect of objective and subjective social isolation on heterogeneous age cohort related to the onset of dementia, which is becoming a social problem due to rapid aging of health issues, was examined through binary logistic regression analysis. Data came from the first wave of Korean Social Life, Health and Aging Project (KSHAP) (N= 814). Findings showed 1) in the young-old, objective isolation was a significant on the incidence of dementia, 2) in the old-old, subjective isolation increased the risk of dementia. In summary, the relative influence of objective and subjective social isolation related to the incidence of dementia varies depending on the young-old and old-old. On the other hand, the interaction effect of objective and subjective social isolation on dementia was not significant in both the young-old and old-old. Based on the findings, we discussed implications and suggestions for future research and relevant policy and program development(dementia-friendly communities) for ameliorating objective and subjective social isolation.

현재, 우리나라 당뇨병의 유병률은 빠른 속도로 증가하고 있으며 당뇨병의 유병기간이 길수록 각종 합병증이 발생하며 더욱 심각한 증세를 나타내기도 한다. 그 중, 비만 및 고혈당, 당대사장애로 인한 당뇨병성 혈관 합병증과 말초 혈관 경화증이 많이 발병하고 있는 실정이다. 본 연구에서는 광혈류량 측정법(Photoplethysmograaphy)으로 손가락에서 얻어진 맥파의 2차 미분 분석을 통해 당뇨병으로 확진된 36명의 당뇨병 환자에 대해 말초혈관 경화도를 연령별로 비교하고자 하였다. 이때 사용한 PPG 파형의 2차 미분 분석 평가 인자는 a와 d이고, d/a는 혈관의 경화도를 의미하며 경화도가 클수록 d/a의 값은 감소하게 되고, 연령이 증가할수록 경화도는 증가하게 된다. 50대 미만의 당뇨병 환자의 d/a값은 $-0.32{\pm}0.12$, 50대는 $-0.48{\pm}0.13$, 60대는 $-0.55{\pm}0.16$, 70대 이상에서는 $-0.59{\pm}0.19$로 연령이 높아질수록 d/a값이 감소하는 것을 확인하였다. 또한, SPSS 13.0 for Windows(SPSS Inc, USA)의 Oneway ANOVA 분석 결과, 연령과 경화도는 통계적으로 유의한 차이를 보였다(p<0.05). 하지만 70대 이상의 당뇨병 환자 그룹에서는 유의한 차이를 확인할 수 없었다. 본 연구에서는 PPG 파형의 2차 미분 분석을 통하여 연령별 당뇨병 환자의 말초혈판 경화도를 비교하였으며, 향후 보완 연구를 통해 비침습적이고 간단한 방법으로 당뇨병 환자의 말초혈관 경화도를 객관적으로 평가하고 진단할 수 있는 시스템 개발로 당뇨병 환자들의 심혈관계질환 사전예방과 치료효과 판정에 도움을 줄 것으로 기대한다.

배경 및 목적: 최근 비디오 흉강경술은 최소 침습적인 수술 방법으로서 자연 기흉의 일반적 치료법으로 인정되고 있으나 비교적 높은 재발율과 비용-효용 관계에 대해서는 논란이 있다. 비디오 흉강경을 이용한 기포 절제술 후의 재발율은 평균 5-10%정도로 보고되고 있으며 이는 개흉술에 비해 상당히 높은 것이다. 또한 국내 의료 실정에서의 개흉술과 비디오 흉강경술의 비용효용에 대한 비교 통계는 없는 상황이다. 대상 및 방법: 1997년 1월부터 1999년 7월까지 일차성 자연기흉으로 성균관 의대 강북삼성병원 흉부외과에서 수술을 시행한 173예를 대상으로 후향적 조사하였다. 비디오 흉강경술로 시행한 104예와 개흉술로 시행한 69예를 양군으로 나누어 성별 및 연령, 발병부위, 수술의 적응증, 수술시간, 술 후 흉관 삽입기간 및 재원 일수, 술후 합병증, 재발율, 수술 경비 및 총치료경비 등을 비교하였다. 결과: 양군의 성별, 연령, 발병부위 등에는 차이가 없었다. 수술 시간은 흉강경군이 73.1$\pm$29.5분, 개흉군이 141$\pm$52분이었다.(p<0.05). 술 후 평균 흉관의 거치기간 및 재원일수는 흉강경군이 각각 3.93일 및 7.5일, 개흉군이 7.0일 및 13.4일이었다.(P<0.05, P<0.05). 술 후 재발한 경우가 비디오 흉강경군에서 6예(5.6%), 개흉군에서 1예(1.4%) 있었다(P<0.05). 본원에서 시행한 비디오 흉강경술과 개흉술의 비교에서 수술로 발생하는 비용은 비디오 흉강경군이 유의하게 높았으나 (1,202,192$\pm$178,992원, 1,005,669$\pm$311,531원; P<0.05) 총 치료비의 비교에서는 유의한 차이가 없었다.(1,946,110$\pm$487,440원, 1,793,912$\pm$308,079원; P=0.18). 결론: 비용 효용관계 및 재발율은 병원마다의 수술 수기 및 퇴원 정책등에 따라서 다소간의 차이가 있을 수 있으나 본원의 조사 결과에서는 비디오 흉강경술이 개흉술에 비해 비용-효과가 있다고 볼 수 없으며 재발율도 높았다.

Objective : The correlation between age of onset and symptoms/severity of panic disorder has not yet been determined. The aim of this research is to determine the different clinical features of panic disorder according to the age of onset. Methods : Patients diagnosed with panic disorder were placed into two groups according to onset of age. The subjects were checked for 13 different panic symptoms presented in the DSM-IV. The investigation was also executed by severity, the anxiety sensitivity index, the scale for depression and anxiety. Results : The early onset group had significantly higher frequencies than the late onset group in the areas of "choking feeling" and "derealization or paresthesia". It was found that only "choking feeling" was statically significant as a risk factor of early onset panic disorder. Among the objective anxiety scale, the subscale of psychological anxiety was higher in the early onset group compared to the late onset group. Conclusion : "Choking feeling" was the only panic symptom that showed a significant difference in accordance with onset age. Earlier onset patients tend to experience a more frequent "choking feeling," which is related to respiratory symptoms. This could mean that earlier onset patients are more likely to have higher psychological anxiety.

Staphylococcus aureus is found on the skin of $78{\sim}100%$ of children and adults with atopic dermatitis (AD) but only on the skin of $2{\sim}25%$ of healthy subjects. It is known that S. aureus and their endotoxins as superantigen have important roles in the exacerbation and prolongation of AD. This study was carried out for the detection of S. aureus in the skin of AD, age, sex, outbreak age of AD, treatment duration, aggravation season, and the relation of ooze and S. aureus. Most patients (84%) with AD show colonization of the skin with S. aureus and there is a correlation between the degree of colonization and the serous exudate. It seems likely that the inhibition of S. aureus is associated with improvement in the skin of AD patients.

This study was to explore demographic, psycho-social and clinical characteristics and the influencing factors on alcohol use of person with severe mental illness in the community. Cross-sectional descriptive design was used to recruit a convenience sample of 176 participants from four community mental health centers in Korea. The collected data were analyzed using t-tests, $x^2$-test, and logistic regression. Depending on the alcohol use (AUDIT-K), participants were divided into the problem alcohol use group (n=54, 30.7%) and normal group (n=122, 69.3%). The problem alcohol use group was significantly more smoking, anxiety, stress, suicidal thought, and had a lower age of onset, phase of rehabilitation, self-efficacy, and others' support. In logistic regression analysis, factors influencing on alcohol use were smoking, age of onset, phase of rehabilitation and others' support. The findings may provide useful information to develop strategies for prevent from alcohol induced the problems in this populations.

Objectives : An early age at onset of obsessive compulsive symptoms in family studies has been strongly associated with a more familial form of obsessive compulsive disorder (OCD). Further, many reports have suggested that early- and late- onset OCD represent separate subtypes of the disorder. The aim of this study was to investigate the associations between the glutamate receptor, the ionotropic, n-methyl-d-aspartate (NMDA) subunit 2B gene (GRIN2B) polymorphisms, and onset of OCD in the Korean population. Methods : We recruited 109 OCD patients and classified them into early- (age of onset <18 years) and late-onset groups (age of onset${\geq}$18). Genomic DNA was extracted from their blood after which the genotypes and allelic frequencies of the two GRIN2B polymorphisms (5072T/G and 5988T/C) were compared in the two groups. We also compared genetic data between child- (age of onset${\leq}$15) and adult-onset groups (age of onset${\geq}$19) using the same protocol. Results : There were no significant differences between the early- and late-onset groups with respect to genotype. Moreover, we could not find any differences in genotype frequencies between child and adult-onset groups. Conclusions : Our study suggested that GRIN2B polymorphisms (5072T/G and 5988T/C) do not affect the onset of OCD in Koreans. However, this finding has resulted from a preliminary study and thus, further study is required.
