Background: Medical skin care is essential for the treatment of skin diseases all over the world. Medical skin care is also part of medical practice and this must be differentiated from the simple skin care that is given for normal healthy skin. Objective: We wanted to discuss medical skin care and the related medical devices and legal issues. Methods: We reviewed the related laws and regulations, we consulted experts and associations and we analyzed the result of the survey. Results: Legally, medical skin care and simple skin care are well classified. However, many illegal procedures are still performed by non-medical personnel and many adverse effects have been reported as a result. Furthermore, there are no legal restrictions for the performer based on the grade of each medical skin care procedure. Conclusion: For the best results and safe procedures, medical skin care must be performed by approved medical equipment under the supervision of a physician or medical personnel. Continuous control and guidance by the government is strongly needed. (Korean J Dermatol 2009;47(11):1236~1245)

목적: 기존에 널리 사용된 PEG의 단점을 보완하고자 새롭게 도입된 PEGA에 있어 점막 내 기포 제거에 주안점을 둔 연구가 없었다. 이에 이번 연구에서 기포 제거제인 simethicone추가군과 대장 점막의 flushing 효과를 기대한 물 1리터 추가군을 두어 대장 정결도, 점막 기포도, 부작용, 환자 만족도 등을 알아보고자 하였다. 대상 및 방법: 전향적 무작위 대조 연구이며, 건강 검진을 위해 내원한 외래 수검자 90명의 환자 중 각각 30명씩 PEGA군, simethicone 추가군, 물 1리터 추가군에 무작위로 배정하여 대장 정결도, 점막 기포도, 환자가 호소하는 부작용 및 만족도를 평가하였다. 결과: PEGA군에서 대장 정결도가 가장 높았으나, 통계적 유의성은 없었다. 점막 기포도는 세 군에서 2.57±2.05 vs.1.10±1.83 vs. 2.60±2.84로 나타났으며, simethicone 추가군이 통계적으로 유의하게 점막 기포도가 낮은 것으로 나타났다(p=0.017). 환자가 호소하는 부작용은 세 군에서 20.0%vs. 16.7% vs. 53.3%로 나타났으며, 물 1리터 추가군이 다른두 군에 비해 통계적으로 유의하게 많은 것으로 나타났다(p=0.003). 환자의 만족도는 세 군에서 3.37±0.85점, 3.73±0.74점, 3.20±0.66점으로 나타났으며, 이들 중 simethicone추가군이 물 1리터 추가군보다 통계적으로 유의하게 높은 것으로 나타났다(p=0.020). 결론: PEGA가 복용량의 감소에도 불구하고 수긍할 만한 대장 정결도를 보였으며, 점막 기포 제거에 있어서 simethicone병합요법이 필요할 것으로 판단된다. Background/Aims: There are no studies that looked into the bubble eliminating efficacy of polyethylene glycol with ascorbic acid (PEGA), which has been one of the shortcomings of polyethylene glycol (PEG). In this study, we compared newly introduced PEGA regimen by adding either simethicone or 1 L of water. Methods: A prospective randomized controlled study was carried out at Dongguk Universtiy Gyeongju Hospital from July 2014 to September 2014. A total of 90 patients were randomly assigned to 3 groups; PEGA group (n=30) which served as control, simethicone addition group (n=30) to which simethicone 400 mg was additionally prescribed, and water addition group (n=30) to whom additional 1 L of water was given. Cleansing effectiveness, gas elimination efficacy, side effects, and patient satisfaction were compared between the groups. Results: PEGA group demonstrated the highest cleansing effectiveness, but there was no statistically significant difference among the groups. Simethicone addition group showed significantly lesser amount of bubbles than the other groups (2.57±2.05 vs. 1.10±1.83 vs. 2.60±2.84, p=0.017). The rates of side effects in each group were 20.00% vs. 16.77% vs. 53.33%. Water addition group had significantly more side effects than the PEGA group and the simethicone addition group (p=0.003). The patient satisfaction score of each group was 3.37±0.85 vs. 3.73±0.74 vs. 3.20±0.66 with simethicone addition group showing significantly higher satisfaction than water addition group (p=0.020). Conclusions: PEGA bowel preparation agent showed satisfactory bowel cleansing despite the decrease in dosage, and addition of simethicone resulted in better bubble elimination.

Background: The decision to administer oral anticoagulation therapy depends on accurate assessment of stroke risk in patients with atrial fibrillation (AF). Various stroke risk stratification schemes have been developed to help inform clinical decision making. The CHADS2 and CHA2DS2-VASc scores have been used in estimating the risk of stroke in patients with AF. Recently R2CHA2DS2-VASc score was developed. The objective of the current study is to validate the usefulness of the R2CHA2DS2-VASc score and to compare the accuracy of the CHADS2, CHA2DS2-VASc, and R2CHA2DS2-VASc scores in predicting a patient’s risk of stroke. Methods: Based on medical records, we conducted a retrospective study of patients hospitalized with AF from March 2011 to July 2013. A total of 448 AF patients were included in this study. The receiver operating characteristic (ROC) curve analysis in MedCalc was used for comparison with respective diagnostic values. Results: The patient characteristics showed male predominance (60.9%). Among the 448 AF patients, 131 (29.2%) patients had strokes during the study. A R2CHA2DS2-VASc score of more than 5 is the optimal cut-off value for prediction of stroke. A risk score of three, the area under the ROC curve (AUC) of R2CHA2DS2- VASc score (AUC 0.631; 95% confidence interval, 0.585-0.679) was the highest. A significant difference was observed between AUC for R2CHA2DS2-VASc, CHADS2, and CHA2DS2-VASc scores, but no meaningful difference between CHADS2 and CHA2DS2-VASc scores. Conclusion: We determined the usefulness of the R2CHA2DS2-VASc score, which showed better association with stroke than the CHADS2 and CHA2DS2-VASc scores.

Background: It is a trend that the average life span is prolonged in proportion to the advance of socio-economy and medical science. Consequently, the number of elderly patients with skin diseases is increasing. Objective: This study was performed to see the change of patterns of skin diseases in elderly patients. Methods: One thousand four hundred and twenty elderly patients, over the age of 65, who visited the departments of dermatology and in five hospitals, from January 1, 1997 to December 31, 1997 were selected. We surveyed the frequeney of skin disease by types and the distributions by month, season and age. Results: The results were as follows; 1. The frequent skin diseases were herpes zoster and postherpetic neuralgia (12.3%), fungal infection (11.3%), pruritus (9.2%), contact dermatitis (6.8%), and seborrheic dermatitis (5.7%). 2. The most frequent was herpes zoster and postherpetic neuralgia in January, February, March, April, June, August and October, in January, July, September and December, fungal infection; in May, contact dermatitis; in November, pruritus. 3. The most frequent skin desease was herpes zoster and postherpetic nueralgia in spring, summer and winter; in autumn, fungal infection. 4. The most frequent skin disease for the 65-74 aged-group was herpes zoster and postherpetic neuralgia; for the over 85 aged group, herpes zoster and postherpetic neuralgia. Conclusion: The results showed that, in contrast to previous studies, herpes zoster and postherpetic neuralgia increased in elderly patients. These findings may be helpful for the government and medical centers to plan and establish a management system on the skin diseases of elderly patients.
