Purpose: Smoking is causally related to alcohol use disorder. Although polycyclic aromatic hydrocarbons (PAHs) are major neurotoxic pollutants in tobacco smoke, evidence is lacking on the role of PAHs in the relationship between smoking and alcohol use disorder. This study investigated the types of PAHs associated with smoking and whether exposure to those PAHs mediated the effect of smoking on alcohol use disorder. Materials and Methods: A total of 968 male firefighters were analyzed. Smoking history and cumulative pack-years were obtained using self-reported questionnaires. Alcohol use disorder was defined using the Alcohol Use Disorder Identification Test.PAH exposure was assessed by urinary metabolites. Regression analyses were performed between exposure (smoking), outcome (alcohol use disorder), and mediator (PAH metabolites) variables. A mediation analysis was performed to test the indirect effect of PAH metabolites on the association between smoking and alcohol use disorder. All analyses were repeated for 770 participants who were followed up after 2 years, while alcohol use disorder was redefined from follow-up data ensuring the temporal sequence of the variables. Results: Both 2-naphthol [β=0.78, 95% confidence interval (CI): 0.59–0.98] and 2-hydroxyfluorene (β=0.69, 95% CI: 0.56–0.82) were associated with smoking history. Furthermore, 2-naphthol and 2-hydroxyfluorene mediated the associations of smoking history (proportion mediated: 14.2%, 23.6% respectively) or cumulative pack-years (proportion mediated: 14.4%, 25.4% respectively) with alcohol use disorder. The results were consistent in longitudinal settings. Conclusion Exposure to PAHs mediated the association between tobacco smoking and alcohol use disorder. PAH exposure from tobacco may increase the risk of addictive disorders.

BACKGROUND/AIMS: Kidney transplantation (KT) reportedly provides a significant survival advantage over dialysis in diabetic patients. However, KT outcome in diabetic patients compared with that in non-diabetic patients remains controversial. In addition, owing to recent improvements in the outcomes of KT and management of cardiovascular diseases, it is necessary to analyze outcomes of recently performed KT in diabetic patients. METHODS: We reviewed all diabetic patients who received living donor KT between January 2008 and December 2011. Each patient was age- and sex-matched with two non-diabetic patients who received living donor KT during the same period. The outcomes of living donor KT were compared between diabetic and non-diabetic patients. RESULTS: Among 887 patients, 89 diabetic patients were compared with 178 non-diabetic patients. The incidence of acute rejection was not different between the diabetic and non-diabetic patients. Urinary tract infection and other infections as well as cardiovascular events occurred more frequently in diabetic patients. However, diabetes, cardiovascular disease, and infection were not significant risk factors of graft failure. Late rejection (acute rejection after 1 year of transplantation) was the most important risk factor for graft failure after adjusting for diabetes mellitus (DM), human leukocyte antigen mismatch, rejection and infection (hazard ratio, 56.082; 95% confidence interval, 7.169 to 438.702; p < 0.001). Mortality was not significantly different between diabetic and non-diabetic patients (0 vs. 2, p = 0.344 by log-rank test). CONCLUSIONS: End-stage renal disease patients with DM had favorable outcomes with living donor kidney transplantation.

It is common to find a nose with a hump, lower nasal tip and a radix among Koreans. A common procedure as an aesthetical improvement for such feature, involves rasping of the hump, while lifting the tip and the bridge at the same time. As for the hump, en bloc resection is a well-known, traditional surgical method, but it may cause an open roof deformity, which leads to a high possibility of infection if dorsal augmentation using silicone was performed through it as it connects the nasal cavity and dorsum. To overcome this complication, the hump on the bony portion and cartilaginous has been improved by a modified autospreader graft. Also, the graft can also be used for tip-plasty in dorsal augmentation using silicone, septal extension graft, strut and onlay graft. As a result of constant monitoring for a year, the reformation of the hump and infection was not found.

OBJECTIVES: This study was conducted to implement Health Plus Happiness Plus projects in Gyeongsangnam-Do and assess the policy implications of initiatives to address regional health inequalities. METHODS: Health Plus Happiness Plus projects were started as strategies to address regional health inequalities in Gyeongsangnam-Do. The principles of these projects are taken from the Health Action Zones initiatives in England: participation, partnership, resource concentration in project areas. The time period for these projects is from 2010 to 2017, and the total budget is 5.6 billion won. In 2010, a 6.8 hundred million won total budget was invested in 17 project areas. Such investments fell into four broad categories: establishment of the means and local framework; survey development to analyze the health determinants; development of an education and training center; and establishment of a technical support center. RESULTS: Education and training programs for practitioners and coordinators were provided, and project teams and project promotion committees were established in project areas. Health survey result briefing meetings were held, and 17 health committees were established in project areas. CONCLUSIONS: Health Plus Happiness Plus projects have some problems in relation to participation and partnerships, however, if these principled projects are performed continuously, they will contribute to a reduction of standardized mortality rate and regional health inequalities in Gyeongsangnam-Do and the improvement of residents' well-being in project areas.

PURPOSE: The aim of this study is to report on preliminary data regarding the prevalence of major eye diseases in Korea. METHODS: We obtained data from the Korea National Health and Nutrition Examination Survey, a nation-wide cross-sectional survey and examinations of the non-institutionalized civilian population in South Korea (n = 14,606), conducted from July 2008 to December 2009. Field survey teams included an ophthalmologist, nurses, and interviewers, traveled with a mobile examination unit and performed interviews and ophthalmologic examinations. RESULTS: The prevalence of visual impairment, myopia, hyperopia and astigmatism in participants over 5 years of age was 0.4 +/- 0.1%, 53.7 +/- 0.6%, 10.7 +/- 0.4%, and 58.0 +/- 0.6%, respectively. The prevalence of strabismus and blepharoptosis in participants over 3 years of age was 1.5 +/- 0.1% and 11.0 +/- 0.8%, respectively. In participants over 40 years of age, the prevalence of cataract, pterygium, early and late age-related macular degeneration, diabetic retinopathy and glaucoma was 40.2 +/- 1.3%, 8.9 +/- 0.5%, 5.1 +/- 0.3%, 0.5 +/- 0.1%, 13.4 +/- 1.5%, and 2.1 +/- 0.2%, respectively. CONCLUSIONS: This is the first nation-wide epidemiologic study conducted in South Korea for assessment of the prevalence of eye diseases by both the Korean Ophthalmologic Society and the Korea Center for Disease Control and Prevention. This study will provide preliminary information for use in further investigation, prevention, and management of eye diseases in Korea.
