Background: Since April 2015, the Korean National Health Insurance (NHI) has reimbursed breast cancer patients, approximately 50% of the cost of the breast reconstruction (BR) procedure. We aimed to investigate NHI reimbursement policy influence on the rate of immediate BR (IBR) following total mastectomy (TM). Methods: We retrospectively analyzed breast cancer data between April 2011 and June 2016. We divided patients who underwent IBR following TM for primary breast cancer into “uninsured” and “insured” groups using their NHI statuses at the time of surgery. Univariate analyses determined the insurance influence on the decision to undergo IBR. Results: Of 2,897 breast cancer patients, fewer uninsured patients (n = 625) underwent IBR compared with those insured (n = 325) (30.0% vs. 39.8%, P < 0.001). Uninsured patients were younger than those insured (median age [range], 43 [38–48] vs. 45 [40–50] years; P < 0.001).Pathologic breast cancer stage did not differ between the groups (P = 0.383). More insured patients underwent neoadjuvant chemotherapy (P = 0.011), adjuvant radiotherapy (P < 0.001), and IBR with tissue expander insertion (P = 0.005) compared with those uninsured. Conclusion IBR rate in patients undergoing TM increased after NHI reimbursement.

PURPOSE: This study aimed to identify multidimensional factors influencing burnout in intensive care unit(ICU) nurses. METHODS: A descriptive cross-sectional design was used. Data were collected during February 2016 from a convenience sample of 222 tertiary hospital ICU nurses and analyzed using t-test, ANOVA, correlation analysis, and multiple regression analysis. RESULTS: Burnout correlated positively with compassion fatigue (CF)(r=.37, p < .001), and negatively with compassion satisfaction (CS)(r=-.66, p < .001). The regression model explained 57% of the variance in burnout. For individual characteristics in the model, perceived health status (β=-.27, p < .001) and gender (β=.14, p=.028) were the most influential factors for ICU nurses' burnout. In the model with added work-related characteristics, nursing environment (β=-.22, p=.001), perceived health status (β=-.20, p=.001), and satisfaction with department (β=-.19, p=.007) were the most influential factors. Finally, for the model with psychological characteristics added, CS (β=-.56, p < .001) and CF (β=.35, p < .001) were the most influential factors. CONCLUSION: Results reveal that most ICU nurses have a moderate level of CF and a moderate to high level of CS and burnout, and that individual, work-related and psychological factors are relevant in ICU nurses' burnout. Programs or interventions to reduce burnout should be developed taking into account these multidimensional factors.

PURPOSE: Allergic rhinitis (AR) is a multifactorial disease whose genetic and environmental risk factors have been studied for decades. Many pediatric studies have pointed out the familial history of allergy, hygiene hypothesis, breast-feeding, pet ownership, and diets as risk factors of AR. However, most of factors are still up for debate. This preliminary report aimed to confirm the known risk factors and find the novel risk factors for AR in the Korean pediatric population. METHODS: A bi-seasonal, winter and summer, study in 2 elementary schools included all students whose parents completed the questionnaire of medical and social histories, quality of life, infant and early-childhood history, and the living styles. Skin prick tests and endoscopic examinations were conducted on all participants. RESULTS: Among total 1,020 children, 338 participants had AR. The multivariate logistic regression analysis highlighted 6 factors: male gender (OR, 2.10; 95% CI, 1.32-3.33), older age (1.65; 1.03-2.65), previous history of allergic conjunctivitis (14.25; 4.99-40.74), asthma (2.73; 0.96-7.76) and pneumonia (0.39; 0.19-0.82), and an hour increase in daily playing time (0.90; 0.80-1.00). CONCLUSIONS: Lack of pneumonia in early childhood and short playing time are newly found risk factors for Korean pediatric AR in this study confirming male gender, older age and previous history of allergic conjunctivitis and asthma as the risk factors.

BACKGROUND AND OBJECTIVES: It is necessary to establish the most efficient diagnostic and therapeutic method for benign paroxysmal positional vertigo (BPPV), which is appropriate for Korean healthcare system. We aimed to evaluate current state of Korean clinician's diagnostic and therapeutic approaches for BPPV. MATERIALS AND METHODS: A 16-item survey was emailed to the members of dizziness department of Otology Research Interest Group in the Korean Otologic Society (n=68). 43 were returned and analyzed. RESULTS: All respondents (100%) used Dix-Hallpike test as a diagnostic tool for vertical canal-BPPV. Supine roll test was used for diagnosing lateral canal BPPV in nearly all the respondents (97.7%). Epley maneuver was chosen as otolith repositioning maneuver (ORM) for posterior canal BPPV in all respondents and barbecue rotation (BBQ) was used for treating lateral canal BPPV with geotropic nystagmus in 95.3% of respondents. Extreme variation was noted for therapeutic approach of lateral canal BPPV with ageotropic nystagmus BBQ, with 4 kinds of ORM and adjunctive measures to liberate otolith from cupula, while BBQ was again the most commonly used ORM (76.7%). CONCLUSION: The development of practical and efficient ORM for lateral canal BPPV with ageotropic nystagmus is necessary.

In patients with severely compromised airways, a tracheostomy is usually performed under local anesthesia. Dexmedetomidine can be a better choice of sedative for such patients because it causes minimal respiratory depression. We report two cases of patients with severe stenosis of the airways who underwent sedation with dexmedetomidine during tracheostomy under local anesthesia. In the first case, recurrent laryngeal cancer caused laryngeal stenosis, and the narrowest laryngeal width was less than 3 mm. In the second case, the tracheostomy opening site was narrowed to a diameter of 3.4 mm in a patient with a history of total laryngectomy. For both patients, sedation was induced by dexmedetomidine infusion and the tracheostomy was performed successfully under local anesthesia without any events. Dexmedetomidine seems to be an effective and safe sedative for tracheostomies in patients with critical airways. The management and implications of sedation with dexmedetomidine in the patients with severe stenotic airways are discussed.

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.

PURPOSE: Metabolic syndrome (MS) has been reported as a potential risk factor of coronary artery disease (CAD). The aims of this study were to assess whether there was a relationship between MS score and CAD angiographic severity, and to assess the predictive value of individual components of MS for CAD. MATERIALS AND METHODS: We retrospectively enrolled 632 patients who underwent coronary angiography for suspected CAD (394 men, 61.0 +/- 10.6 years of age). MS was defined by the National Cholesterol Education Program criteria with the waist criterion modified into a body mass index (BMI) of more than 25 kg/m2. The MS score defined as the number of MS components. CAD was defined as > 50% luminal diameter stenosis of at least one major epicardial coronary artery. CAD angiographic severity was evaluated with a Gensini scoring system. RESULTS: Of the patients, 497 (78.6%) had CAD and 283 (44.8%) were diagnosed with MS. The MS score was significantly related to the Gensini score. High fasting blood glucose (FBG) was the only predictive factor for CAD. A cluster including high FBG, high blood pressure (BP), and low high-density lipoprotein cholesterol (HDL-C) showed the highest CAD risk. CONCLUSION: The MS score correlates with the angiographic severity of CAD. The predictive ability of MS for CAD was carried almost completely by high FBG, and individual traits with high BP and low HDL-C may act synergistically as risk factors for CAD.

OBJECTIVE: Although increased expression of receptor for advanced glycation end products (AGE) in osteoarthritis (OA) has been reported, little is known concerning the role of AGEs in the pathogenesis of OA. This study was undertaken to determine the effect of AGEs on the regulation of matrix metalloproteinase (MMP) expressions and activities in human OA chondrocytes METHODS: OA chondrocytes were treated with increasing doses of AGE-bovine serum albumin (AGE-BSA). The expressions of MMPs were determined by both enzyme-linked immunosorbent assay (ELISA) and immunoblot analysis. The activities of MMPs were evaluated by both gelatin and casein zymography assays. In addition, electrophoretic mobility shift assay (EMSA) was employed to investigate the DNA binding activity of nuclear factor-kappa B (NF-kappaB) by AGE-BSA treatment. RESULTS: The productions of MMP-1, -3, and -13 were significantly elevated by AGE-BSA in a dose dependent manner. The elevated activities of MMP-1, -3, and -13, and TNF-alpha by AGE-BSA were also observed. DNA binding activity of NF-kappaB was markedly increased by AGE-BSA treatment implicating possible involvement of NF-kappaB mediated pathway in the AGE-BSA induced MMP-1, -3, and -13, and TNF-alpha productions in OA chondrocytes. Taken together, this study demonstrates the stimulatory effect of AGE-BSA on the productions of MMPs and TNF-alpha and suggests the possible involvement of NF-kappaB mediated pathway in OA chondrocytes. CONCLUSION: These results suggest that AGE may play a role in pathogenesis of OA.

BACKGROUND: Recently, ghrelin has been reported to be associated with insulin resistance. Nonalcoholic fatty liver disease (NAFLD) is a condition in which insulin resistance relatively plays a pivotal role. The aim of this study was to evaluate the change of serum ghrelin concentration according to severity of hepatosteatosis. METHODS: Sixty five apparently normal male adults who underwent health screen examinations were classified into three groups, Group I: normal (27 subjects), Group II: mild (24 subjects) and Group III: moderate to severe fatty liver (14 subjects), according to ultrasonographic findings of liver. We analyzed the association between serum ghrelin concentration and severity of hepatosteatosis by ANOVA test. And the independent correlation between serum ghrelin concentration and insulin resistance related factors, HOMA (homeostatic model assessment), BMI (body mass index), WC (waist circumference), HC (hip circumference), WHR (waist to hip circumference ratio) were analyzed by multiple linear regression analysis. RESULTS: Serum ghrelin concentration tended to decrease according to severity of hepatosteatosis (Group I: 230.9+/-94.3, Group II: 195.2+/-97.2, Group III: 164.3+/-71.4 pmol/L). But this was statistically insignificant (p=0.081). The independent correlation between serum ghrelin concentration and insulin resistance related factors were not observed. CONCLUSIONS: Our study did not prove the correlation between insulin resistance related factors and serum ghrelin concentration in NAFLD according to severity of hepatosteatosis. However, we found a tendency to decrease serum ghrelin concentration according to severity of hepatosteatosis. So, further studies are required for certification these correlations.
