Increases in cardiovascular disease (CVD) in modern society are attributable to aging and lifestyle changes such as westernized diet and decreased physical activity. On the other hand, mounting evidence suggests that environmental pollutants such as persistent organic pollutants (POPs), bisphenol A (BPA) and phthalates are also related to the increases in CVD. POPs are a family of lipophilic stable chemicals that accumulate in adipose tissue and create a persistent toxic effect. The association between POPs and CVD is reported through epidemiologic, animal and in vitro studies. The association between BPA and CVD has also been established from many epidemiologic studies; however, a causal relationship remains uncertain. Exposure to POPs or BPA is also associated with the development of well-known CV risk factors such as type 2 diabetes mellitus, hypertension, hypercholesterolemia and obesity. Therefore, it is uncertain whether POPs and BPA are involved directly to the pathogenesis of atherosclerosis or indirectly associated with CVD. Additional longitudinal and experimental studies searching for the direct causal relationship and exact linking mechanisms should be conducted to investigate the effect of exposure to environmental pollutants such as POPs and BPA.

PURPOSE: To establish the incidence of deep vein thrombosis among Koreans after primary total hip arthroplasty and the usefulness of color doppler ultrasonography for routine noninvasive screening for deep vein thrombosis. MATERIALS AND METHODS: We performed prospective, randomized routine venography and color doppler ultrasonography before and after operation in a consecutive series of 89 primary total hip arthroplasty in which no form of prophylaxis was used. RESULTS: Of the 89 cases, eleven (12.4%) were found to have deep vein thrombosis (three proximal veins and eight distal veins) by bilateral venography. Most of the thromboses except two were asymptomatic. No patient had a symptomatic pulmonary embolism. Statistical analysis of risk factors, age, gender, weight, height, fixation method, and duration of operation time, were performed and there was no statistical difference (P>0.05). The reliability of color doppler ultrasonography for detection of deep vein thrombosis was demonstrated. CONCLUSIONS: We found insufficient evidence to recommend routine thromboprophylaxis in primary total hip arthroplasty among Koreans. The authors recommend that routine bilateral color doppler ultrasonography screening be considered after primary total hip arthroplasty for detection of deep vein thrombosis

Background: Ablative fractional CO2 laser treatment is popular for improving atrophic acne scars; however, complications after laser treatment are unavoidable. The purpose of this study was to investigate the efficacy and safety of a moisturizer containing Centella asiatica extract when applied after ablative fractional CO2 laser resurfacing. Methods: A split-face study was conducted between September 2020 and December 2020 on 34 patients (16 females and 18 males) who were treated with ablative fractional CO2 laser resurfacing. After laser treatment, C. asiatica extract was applied to the right side of the face and purified water was applied to the left side. We compared the right and left sides of the face at various time points after laser treatment using an automatic skin analysis device to investigate the degree of moisture and post-inflammatory hyperpigmentation. Results: No significant difference in the degree of moisture was found between the two sides of the face immediately after laser treatment (P=0.059), but there was a significant difference at 1 and 4 hours after post-laser treatment care (P<0.001). Regarding post-inflammatory hyperpigmentation, there was no significant difference between the two sides of the face before laser treatment (P=0.184), but a significant difference was found at 6 weeks after laser treatment (P<0.001). Conclusions Our results show that applying C. asiatica extract is a novel post-laser treatment modality that can provide satisfactory results without complications after ablative fractional CO2 laser resurfacing.

BACKGROUND: EMLA cream is a eutectic mixture of lidocaine and prilocaine and has excellent anesthetic effect on tympanic membrane but histologic influence on tympanic membrane is uncertain. OBJECTIVE: To investigate its histologic effects on tympanic membrane. MATERIALS AND METHODS: 18 Sprague-Dawly rats were divided into 6 groups. Each group was treated with application of EMLA cream into external ear canal and then were sacrificed at 4 hours, 24 hours, 3 days, 7 days, and 14 days after application of the agents. RESULTS: 1) Transmission electron microscopy revealed partial loss of epithelial cell at 4 hours after application of the agents. 2) The specimen showed damaged cells in the epidermal layer and partial loss of basement membrane at 24 hours after application of the agents. 3) At 1 week after application of the agents epidermal layer and inner epithelium with connective tissue predominated. Thus the fibrous layer represent only 1/3 of total drum thickness. In the basal layers widened intercellular spaces were noted. 4) At 2 weeks after application of the agents newly formed connective tissue was found at fibrous layer and numerous fibroblasts were noted at inner epithelial layer. but overall histologic changes of the drum were not significant and healing processes was noted. CONCLUSION: EMLA cream has less histopathologic effects on tympanic membrane, and early recovery process occurred.

OBJECTIVE: We investigated serum lipid levels in asymptomatic HBsAg carriers and the general population using the Korean National Health and Nutrition Examination Survey (KNHANES). METHODS: We analyzed the data of patients aged ≥30 years from the KNHANES 2007-2014 datasets. Subjects with diabetes mellitus, triglyceride levels >1000 mg/dL, a history of heavy alcohol consumption, or lipid-lowering medication were excluded. HBsAg carriers were divided into “unknown HBsAg carrier” and “known HBsAg carrier” according to previous self-recognition of HBsAg status using a questionnaire. RESULTS: Compared with control subjects (n=24,880; male 33.9%; mean age 52±14 years), HBsAg carriers (n=1,061; male 40.6%; mean age 50±13 years) showed significantly higher AST and ALT levels, lower platelet counts and higher body mass index (BMI) (all p<0.001). HBsAg carriers revealed lower total cholesterol, LDL cholesterol and triglyceride levels (all p<0.001) compared with control subjects, irrespective of previous awareness of HBsAg positivity. Hypertriglyceridemia and low HDL cholesterolemia were less prevalent even in the “unknown HBsAg carrier” group compared with control subjects [age, sex and BMI-adjusted odds ratio, 0.566 (95% confidence interval, 0.468-0.684) and 0.822 (0.708-0.956), respectively]. CONCLUSION: In conclusion, HBsAg carriers exhibited low total cholesterol, LDL cholesterol, and triglyceride levels compared with control subjects. Hypertriglyceridemia and low HDL cholesterolemia were also less frequently detected in HBsAg carriers even after adjustments for age, sex, and BMI.

In the early 2000s, the prevalence of diabetes in adults aged ≥30 years in Korea was about 9% to 10%, and it remained stable. However, a nationwide survey showed that this prevalence increased over the past few years. After age-standardization using the Korean population of the year 2010, the prevalence of diabetes in adults aged ≥30 years was 10.0% to 10.8% between 2001 and 2012, which increased to 12.5% in 2013 and 11.6% in 2014. During that period, there have been changes in the gender- and age-specific prevalence of diabetes in Korean adults. The prevalence of diabetes in the elderly population increased significantly, while this prevalence in young adults, especially in young women, did not change significantly. The contribution of each diabetic risk factor, such as obesity, β-cell dysfunction, sarcopenia, and socioeconomic status, in developing diabetes has also changed during that period in each gender and age group. For young women, obesity was the most important risk factor; by contrast, for elderly diabetic patients, sarcopenia was more important than obesity as a risk factor. Considering the economic burden of diabetes and its associated comorbidities, a public health policy targeting the major risk factors in each population might be more effective in preventing diabetes.
