PURPOSE: This study investigated various factors relatied to wandering behavior of Korean elders with dementia (KED). METHODS: A sample of 160 ambulatory residents with dementia from 14 long term care facilities was used to examine demographic, individual, cognitive, physical health, and environmental characteristics by comparing wanderers (N=108) to nonwanders (N=52). Subjects were evaluated by Korean versions of the Mini-mental State Exam (K-MMSE), the Physical and Instrumental Activities of Daily Living (K-PIADL), and the Revised Algase Wandering Scale Nursing Home version (KRAWS-NH) along its six dimensions. Demographic and environmental data were also obtained. Independent sample ttests, Chi-square test, Fisher's Exact tests, and ANCOVAs were used to examine differences between wanderers and nonwanders. RESULTS: Wanderers were significantly (p<.05) older and had more limitations in K-PADL and K-IADL. The degree of overall wandering and certain features of wandering were significantly different (p<.05) by total number of residents in the facility, type of bedroom (i.e., "Ondol"), and color of bedroom and living-room walls (i.e., sky blue). CONCLUSIONS: Findings of this study may be useful in understanding wandering behavior of KEDs and thus developing more culturally specific management strategies.

PURPOSE: The purpose of this study was to examine the level of intention to quit smoking and to identify factors influencing intention to quit among patients with coronary heart disease. Method: The subjects consisted of 80 male patients with coronary heart disease (angina pectoris, myocardial infarction) at three hospitals in Seoul. The data were collected with self reporting in a structured questionnaire. Stepwise multiple regression was used to identify predictors of intention to quit. Included variables were attitudes toward smoking cessation, subjective norms, perceived behavioral control, usefulness of smoking cessation, and previous attempts to quit. RESULT: 1. The mean score for intention to quit was 11.1(+/-6.1) which was lower than median score of the scale. 2. There were significant correlations between the all predictive variables and the intention to quit(r=.24-.48, p<.05). 3. usefulness of smoking cessation, perceived behavioral control, and previous attempts to quit explained 34.6% of the variance for intention to quit. CONCLUSION: usefulness of smoking cessation, perceived behavioral control, and previous attempts to quit were identified as important variables in explaining the intention to quit smoking among patients with coronary heart disease. Thus, it is necessary to try to enhance this factors for increasing intention to quit among patients with coronary heart disease.

A case of Factor V deficiency, the first case in Korea, is reported in a 9-year-old boy whose plasma concentration of Factor V was 6%. He complained of easy bruisability, prolonged bleeding from the mouth after minor trauma and hemarthrosis and flexion contracture of the right knee. His parents are heterozygous (maternal Factor V concentration 52%, paternal 40%).

BACKGROUND: In Korea, 17-alpha-hydroxyprogesterone (17-OHP) neonatal screening for congenital adrenal hyperplasia (CAH) has a high false positive rate. Preterm infants have higher levels of 17-OHP than term infants. We established the separate cutoff values of 17-OHP under the guideline of the Clinical and Laboratory Standard Institute C28-A3 to reduce a false positive rate. METHODS: The 17-OHP enzyme-immunoassay was used in blood spots of 22,601 newborns. To decide whether to partition cutoff values based on sex, sampling date and birth weight was assessed by Z-test and standard deviation (SD) ratio. If the result was significant, we estimated the cutoff value with 90% confidence intervals (CIs) using the nonparametric method. RESULTS: In the subclasses based on sex and sampling date, the results were not significant. However, the birth weight-adjusted subclasses (SD ratio > 1.5) showed that it was necessary to distinguish low-birth-weight infants from the others. We selected the subclass categories to reflect the concept of low- or very-low-birth-weight infant. The maximum percentile to define a 90% CI was chosen in each subclass. After applied the re-estimated cutoff value, the recall rate was decreased from 0.6% to less than 0.2%. CONCLUSIONS: The birth weight-adjusted cutoff value of 17-OHP in neonatal screening for CAH can be reduced the false positive rate of low-birth-weight infants. This approach would decrease unnecessary blood draws, medical evaluation, parental anxiety and burden on health care resources.

PURPOSE: Dermatofibrosarcoma protuberans (DFSP) carries a translocation resulting in the collagen type I alpha 1 (COL1A1)-platelet-derived growth factor beta (PDGFB) fusion gene, which is responsible for PDGFB activation. The purpose of this study is to evaluate the clinicopathological, genetic, and therapeutic features of DFSP in Korean patients. MATERIALS AND METHODS: Clinicopathological features of 37 patients with DFSP were reviewed. Multiplex reverse transcriptase-polymerase chain reaction (PCR) was carried out in 16 patients using formalin-fixed, paraffin-embedded tissues and specific primers for COL1A1 and PDGFB. RESULTS: The mean age of 37 patients was 37.4 years old. The most common tumor location was the trunk. All patients were treated primarily with surgery: 34 (91.7%) cases with Mohs micrographic surgery (MMS) and 3 (8.3%) cases with wide local excision. The median follow-up time was 33.7 months. Two patients, one in each treatment group, demonstrated local recurrence during the follow-up period. The COL1A1-PDGFB fusion gene was expressed in 14 (87.5%) cases, demonstrated by reverse transcriptase PCR analysis. No association was found among the different COL1A1-PDGFB fusion transcripts, the various histological subtypes and clinical features. CONCLUSION: Our results support the effectiveness of MMS in treating DFSP. The COL1A1-PDGFB fusion transcript was observed in 87.5% of patients. Therefore, COL1A1-PDGFB is a useful and accurate tool in diagnosing DFSP in Koreans.

Background: Glomus tumors are benign mesenchymal neoplasms originating from the subcutaneous glomus body. It is often described as a painful nodule accompanied by tenderness and temperature sensitivity. Objective: To analyze the clinicopathologic features of glomus tumors and determine the correlations between the characteristics of glomus tumors and those of the patients. Methods: We reviewed the medical records and biopsy specimens of 29 cases of glomus tumors diagnosed between June 2006 and May 2021 at a single tertiary hospital. Results: The male to female ratio was 2.6:1, and the mean age of onset was 44.3 years. All cases presented with a solitary lesion, and the most common location was the fingernail (15 cases, 51.7%). Sixteen tumors (55.2%) were located in the digits, all of which were subungual tumors. Among these, nine tumors (56.3%) were observed in the nail bed, and seven (43.7%) were observed in the nail matrix. Thirteen patients (44.8%) had extradigital tumors.Histopathologically, 12 cases were solid glomus tumors (41.4%), 15 were glomangiomas (51.7%), and one was a glomangiomyoma (3.4%). Myxoid stromal changes were observed in nine cases (31.0%), all of which were subungual tumors. All tumors were removed. Postoperative nail deformities were observed in eight cases (50% of subungual tumors). Conclusion At our clinic, glomus tumors were commonly seen as solitary nodules accompanied by pain or tenderness. More than half of the tumors were located in the subungual area, mostly in the fingernails. Tumor removal alleviated the symptoms in most cases, but often resulted in residual nail dystrophy.

As the usage of biologics for rheumatic diseases increases, such as rheumatoid arthritis and ankylosing spondylitis, various cutaneous adverse events are also being increasingly reported. We experienced a case of development of vitiligo during a TNF-alpha antagonist therapy in a 22-year-old woman with rheumatoid arthritis. The patient was presented with vitiligo lesions on the dorsum of both hands after 1 month of treatment with etanercept. Vitiligo improved with topical tacrolimus ointment and excimer laser treatment without the discontinuation of etanercept. No clearly defined mechanism for vitiligo induced by TNF-alpha antagonist exits. However, considering that vitiligo is an autoimmune disorder, the development of this skin lesion in association with the TNF-alpha antagonist could be explained by a paradoxical induction of the autoimmune process.
