Esophagea1 achalasia is a disease of unkown etiology characterized by abscenee of peristalsis in the body of the esophagus and failure of the lower esaphageal sphincter to relax in response to swallow. The cause has been suggested by the lack or abscence of ganglion cell in Auerbach's plexus. About 10% of patients with achalasis develop pulmonary complication such as aspiration pnuemonia, pulmonary fibrosis, pulmonary tuberculosis, culosis, bronchiectasis, lung abscess and bronchial asthma. Although aspiration pneumonia is the most common pulmonary complication in patients with achalasia, lung abscess is the extremely rare complication. A 48 years old female, who has experienced dysphagia and regurgitation for several years, is hospitalized because of high fever, cough and sputurn for 2 weeks. Lung abscess in apicoposterior segment of left upper lobe is observed in X-ray and chest CT. The findings of esophagogram, esophagogastroscopy and esophageal manometry are consistent with achalasia. We report a case of lung abscess associated with achalasia.

Objectives The aim of this study was to determine the association between low-level mercury exposure and neurobehavioral functions in adults living in coastal regions of Korea. Methods We selected 172 adults aged 20-65 years living in a city in the coastal region of Korea. A sociodemographic survey was conducted, mercury levels in the blood, urine, and hair were measured, and the associations according to computerized neurobehavioral tests were determined using univariate analysis. After adjustment for associated variables, a multivariate linear regression analysis was performed. Results The geometric mean mercury levels in the blood, urine, and hair were 5.41 ㎍/L (range, 0.00-15.84 ㎍/L), 1.17 ㎍/g-creatinine (range, 0.00-32.86 ㎍/g-creatinine), and 1.37 ㎎/㎏ (range, 0.42-6.56 ㎎/㎏), respectively. Variables that were associated with simple reaction time according to the neurobehavioral test results were age and urine mercury level. Variables associated with choice reaction time were the recent use of Korean traditional medicine and urine mercury level. Variables associated with the right-hand finger tapping speed test were age, gender, smoking behavior, education level, monthly household income, and urine mercury level. Variables associated with the left-hand finger tapping speed test were age, gender, education level, and urine mercury level. After adjustment for associated variables, there was no significant association between urine mercury level and simple reaction time (β=25.96; p =0.47), choice reaction time (β=50.37; p =0.32), or the number of left-hand finger taps (β=-1.54; p =0.21). However, urine mercury level was significantly associated with the number of right-hand finger taps (β=-3.86; p =0.01). Conclusions We found no evidence that low-level mercury exposure in adults is associated with deficits in neurobehavioral functions. A longer follow-up study is required to confirm this conclusion.

Epidemiology of myocardial infarction in Korea: hospitalization incidence, prevalence, and mortality

Kim Rock Bum,김장락,황진용 한국역학회 2022 Epidemiology and Health Vol.44 No.-

Few studies have comprehensively presented epidemiological indicators of myocardial infarction in Korea. However, multiple published articles and open-source secondary data on the epidemiology of myocardial infarction are now available. This review summarized the hospitalization incidence, prevalence, and mortality rate of myocardial infarction in Korea using articles and open-source data from the Health Insurance Service and the Department of Statistics, surveys of sample populations, registries of patients, and other sources. The epidemiological indicators of myocardial infarction were compared between Korea and other high-income countries. The incidence of hospitalization due to myocardial infarction in Korea was 43.2 cases per 100,000 population in 2016 and has consistently increased since 2011. It was 2.4 times higher among men than among women. The estimated prevalence among adults over 30 years of age ranged from 0.34% to 0.70% in 2020; it was higher among men and increased with age. The mortality in 2020, which was 19.3 per 100,000 population in 2020, remained relatively stable in recent years. Mortality was higher among men than among women. Based on representative inpatient registry data, the proportion of ST-elevated myocardial infarction decreased until recently, and the median time from symptom onset to hospital arrival was approximately 2 hours and 30 minutes. The hospitalization incidence, prevalence, and mortality rate of myocardial infarction were lower in Korea than in other countries, although there was an increasing trend. Comprehensive national-level support and surveillance systems are needed to routinely collect accurate epidemiological indicators.

( Ji Sung Bok ),( Minyoung Kim ),( Yun-hong Cheon ),( Sang-il Lee ),( Rock-bum Kim ),( Ki Soo Park ),( Hyung Bin Park ),( Jae-bum Na ),( Hyun-ok Kim ),( Young Sun Suh ) 대한내과학회 2016 대한내과학회 추계학술대회 Vol.2016 No.1

Background: Rotator cuff tear (RCT) and hand osteroarthritis (HOA) are commonly accompanied because they share a similar pathogenesis. However, there was no previous study investigating the relationship between RCT and HOA. Objectives: To estimate the prevalence and associated factors of RCT in patients with HOA. Methods: In this study, we enrolled 1150 individuals who lived in Gyeongnam province in Korea from June 2013 to December 2015. Physical examinations were performed by rheumatologists and orthopedists. Plain radiography of hands and magnetic resonance imaging (MRI) of shoulders were performed in all participants. Serum levels of high sensitive C reactive protein (hsCRP) and high density lipoprotein (HDL) were checked. RCT was diagnosed by clinical examination and MRI findings. Diagnosis of HOA was made by the 1990 American College of Rheumatology classification criteria. Severity of radiographic HOA was assessed by sum of Kellgren-Lawrence (KL) grades of total involved joints on plain radiographs. Results: The prevalence of RCT was higher in patients with HOA group (192/307, 62.5%) than those without HOA (410/827, 49.5%, p<0.001). Among 307 with HOA, patients with RCT were older (62.69±7.04 vs. 59.11±7.69, p<0.001) and showed higher hsCRP (1.51±3.78 vs. 0.67±0.70, p=0.004) and lower HDL levels (55.66±15.46 vs. 60.48±12.45, p=0.003) compared to those without RCT. Multiple logistic regression analysis showed significant associations of age (odds ratio [OR] 1.06; 95% confidence interval [CI] 1.016 - 1.099), serum levels of hsCRP (OR 1.37, CI 1.043 - 1.794), and low HDL (male <50mg/dL, female <40mg/dL) (OR 2.16, CI 1.160 - 4.005) with RCT in HOA patients. Conclusions: The prevalence of RCT is high and age and serum levels of hsCRP and HDL have predictive roles in the development of RCT in HOA patients.

Relationship Between Blood Mercury Concentration and Waist-to-Hip Ratio in Elderly Korean Individuals Living in Coastal Areas

You, Chang-Hun,Kim, Byoung-Gwon,Kim, Jung-Man,Yu, Seung-Do,Kim, Yu-Mi,Kim, Rock-Bum,Hong, Young-Seoub The Korean Society for Preventive Medicine 2011 Journal of Preventive Medicine and Public Health Vol.44 No.5

Objectives: This study investigated the relationship between the blood mercury concentration and cardiovascular risk factors in elderly Korean individuals living in coastal areas. Methods: The sample consisted of 477 adults (164 males, 313 females) aged 40 to 65 years who visited a Busan health promotion center from June to September in 2009. The relationship between blood mercury concentration and cardiovascular risk factors including metabolic syndrome, cholesterol profiles, blood pressure, body mass index (BMI), waist circumference and waist-to-hip ratio (WHR), was investigated. Variables related to blood mercury concentration were further evaluated using multiple regression analysis. Results: The blood mercury concentration of the study population was 7.99 (range, 7.60 to 8.40) ${\mu}g$/L. In males, the blood mercury concentration was 9.74 (8.92 to 10.63) ${\mu}g$/L, which was significantly higher than that in females (7.21, [6.80 to 7.64] ${\mu}g$/L). The blood mercury concentration of the study population was related to several cardiovascular risk factors including low-density lipoprotein (LDL) cholesterol (p=0.044), high-density lipoprotein (HDL) cholesterol (p=0.034), BMI (p = 0.006), waist circumference (p = 0.031), and WHR (p < 0.001). In males, the blood mercury concentration was significantly correlated with WHR in the multiple regression analysis. Conclusions: In males, the blood mercury concentration was related to waist-to-hip ratio, which is a central obesity index and cardiovascular risk factor. Our finding suggests that cardiovascular disease risk in males was increased by mercury exposure via an obesity-related mechanism.
