  • Introduction: After 17 years since the first production of humidifier disinfectants in Korea, Korea Centers for Disease Control and Prevention (KCDC) announced that the odds ratio of lung injury related with humidifier disinfectant usage was 47.3 (95% confidence interval 6.0-369.7) according to a case-control study with 18 adult cases, including 8 pregnant women at a university hospital in Seoul. Results: From September 2011 to April 2012, one-hundred and seventy four victim cases have been reported to an environmental non-governmental group (NGO). We summarized timetable of humidifier disinfectants accidents, analyzed health outcomes (death, lung or lung and heart transplantation, pulmonary disease) of reported victims, and classified some information for humidifier disinfectants with health outcomes, and government action for this accident. Among the victims, number of death cases are 52 (30.0%), including 26 babies less than 3 years old. Sixty-nine victims come from twenty-seven family with 2 to 4 members per family. About twenty types of humidifier disinfectant products and about 600,000 product items a year have been sold. Fifty-two death cases used 7 different types of disinfectant products, including imported goods and some private brands of well-known supermarkets. KCDC confirmed inhalation toxicity of 6 products through an animal experimental test, and based on this observation recalled disinfectants containing PHMG (polyhexamethylene guanidine) and PGH (Oligo(2-(2-ethoxy)ethoxyethyl guanidinium chloride). Discussions: The use of these biocides involved highly fatal consequences among biologically vulnerable victims, such as pregnant women, several family member victims after semi-acute exposure. This is the first biocide disaster in Korea with non-specific targets, and unknown scale of victims, warranting concerns on use of biocides in the living environment. Conclusions: Special administrative agency for chemical safety and compensation act for environmental health victims are needed to prevent similar problems.

  • Purpose: To determine the efficacy of post-operative chemotherapy with cisplatin plus vinorelbine (NP) in Chinese patients with non-small cell lung cancer (NSCLC). Methods: A total of 451 patients with NSCLCs at stages I, II, and IIIA after surgical resection were treated with cisplatin plus vinorelbine for 4 cycles or volunteers observed between January 2002 and November 2004 and were followed for five years. The therapeutic efficacy was evaluated with reference to overall survival (OS) and disease-free survival (DFS), and adverse effects were also recorded. Potential factors affecting the lengths of OS and DFS were analyzed by multivariate analysis. Results: Most patients (86.7%) completed at least 4 cycles of treatment. Patients with chemotherapy survived significantly longer than those in the observation group (p<0.001). The absolute improvements in the 2 and 5-year OS were 3.8% [hazard ratio (HR) =0.674, 95% confidence interval (CI): 0.554-0.820, P<0.0001] and 13.0% (HR=0.732, 95% CI: 0.579-0.926, P=0.009), respectively. The improvement at 4-year DFS was 2.1% (HR=0.327, 95% CI: 0.214-0.500, P<0.0001). Stratification analysis revealed that older age, histological type, pathological degree, but not the gender and smoking status, are independent factors affecting the length of survival in this population. Many patients (63.3%) had grade 1-III tolerable adverse effects, and there was no treatment-related death. Conclusions: Post-operative chemotherapy with NP regimen is effective and tolerable in Chinese patients with NSCLC.

  • Purpose: This study was conducted to compare demographic and characteristic differences in self-poisoned patients by age groups using a comprehensive trauma database. Methods: This study included 1,823 patients who were admitted to the emergency room following self-poisoning. Three age groups were defined: young patients (less than 19 years), adult patients (19 to 64 years) and elderly patients (65 years and old). From January 2011 to December 2015, data were obtained from in a single emergency medical center. We investigated the materials of poisoning, ingestion time, GCS, systolic blood pressure, heart rate, and outcomes of patients. Results: A total of 1,823 self-poisoned patients visited the hospital during 5 years. Among these, 130 (7.1%) were categorized as young, 1,460 (80.1%) were adults and 233 (12.8%) were elderly. The most common drug of self-poisoning substances was antipyretics (50.0%) for those in the young group, sedative drugs (45.0%) for adults, and pesticides (41.2%) for the elderly. Mortality was 2.7% in the adult group and 14.6% in the elderly group. After adjusting for all factors related to mortality, the odds ratio (OR) of mortality was 2.63 in the elderly group (95% confidence interval [CI]: 1.44-4.81). Conclusion: There were definite differences in the characteristics of three groups. The younger patients used drugs that could be easily obtained while older patients used more lethal drugs.

  • 목격자 심폐소생술 시행률을 높이는 핵심 방안 중 하나가 학생들에게 심폐소생술 교육을 하는 것이다. 본 연구의 목적은 보건교사가 실시하는 중학생 심폐소생술 교육의 결과를 교육 전 수준과 비교 검증하는 것이다. 2014년 3월부터 6월까지 부산광역시 중학생 812명을 대상으로 교육 전과 후의 관찰 값을 SPSS, SAS프로그램을 사용하여 카이검정과 맥네머 검정으로 분석하였다. 대상자의 성별과 과거교육 경험을 층하한 후 각 층하군에서 인식, 의지 및 자신감의 모든 항목에서 교육 전보다 교육 후에 통계적으로 유의하게 긍정적인 변화가 관찰되었다(p<0.05). 목격자 심폐소생술이 더 많이 실시되기 위해서는 중학생에게 보건교사가 이론과 실습으로 구성된 심폐소생술 교육을 실시하는 것이 바람직하다고 판단된다. 이러한 교육의 실현을 위하여 교육 도구의 공급을 위한 지역사회의 정책 개발을 위한 추가적인 연구가 더 필요할 것으로 생각한다.

  • Objectives: A positive association between serum albumin levels and metabolic syndrome has been reported in observation studies, but it has not been established in the Korean population. The purpose of this study was to evaluate the association between serum albumin levels and the presence of metabolic syndrome among a sample of apparently healthy Korean adults. Methods: This cross-sectional study analyzed data of 3189 community-dwelling people (1189 men and 2000 women) who were aged 40 to 87 years and were living in a rural area in Korea. Serum albumin levels were classified into quartile groups for each sex. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III guidelines with an adjusted waist circumference cut-off value ${\geq}90\;cm$ for men and${\geq}85\;cm$ for women). An independent association between serum albumin levels and metabolic syndrome was assessed by multiple logistic regression analysis. Results: Higher serum albumin levels were associated with increased prevalence of metabolic syndrome. The odds ratio (95% confidence interval) of the prevalence of metabolic syndrome for the highest versus the lowest serum albumin quartiles was 2.81 (1.91 to 4.14) in men and 1.96 (1.52 to 2.52) in women, after adjusting for age, smoking status, alcohol consumption, and physical activity. When each metabolic abnormality was analyzed separately, higher serum albumin levels were significantly associated with hypertriglyceridemia and hyperglycemia in both sexes, and with abdominal obesity in men. Conclusions: These results suggest that higher serum albumin levels are positively associated with an increased risk of metabolic syndrome in Korean adults.

  • Purpose: Clinical observation and research findings show that acute traumatic coagulopathy (ATC) is a major factor that must be addressed in the early care of severe trauma patients. ATC is associated with increased transfusion requirements and poor clinical outcomes. This study aimed to correlate the early predictable factors of ATC with the outcomes in severe trauma patients. Methods: Retrospective data from the trauma registry on severe trauma patients (Injury Severity Score (ISS) ${\geq}16$) were used to identify variables independently associated with coagulopathy. Univariate associations were calculated, and a multivariable logistic regression analysis was used to determine variables independently associated with ATC. Results: Patients were mostly male, aged $51.9{\pm}17.8$ years, with an injury severity score of $24.1{\pm}12.4$. ATC, as diagnosed in the emergency department (ED), occurred in 17% of the severe trauma patients. Using a multivariable logistic regression analysis, early predictable variables independently associated with ATC were base deficit (odds ratio (OR): 13.03; 95% confidence interval (CI): 3.47-48.93), acute liver injury (OR: 4.24; 95% CI: 1.06-17.00), and transfer from another hospital (OR: 21.00; 95% CI: 3.23-136.60). Conclusion: ATC is associated with mortality in severe trauma patients, and some variables associated with trauma and shock are an independent predictors of ATC. These variables contribute to the early recognition and management of coagulopathy, which may improve the outcome from trauma resuscitation.
