Although acute occupational poisonings are very rare officially, it seems that there are a considerable number of unreported cases seen from non-intentional poisoning cases of the national injury and poisoning survey on discharged patients. Establishing a proper national surveillance system for acute occupational poisonings is needed. It is difficult for clinical physicians to diagnose acute occupational poisonings appropriately because the victims who usually are not mentally alert can not provide the information on the workplace hazard. Consulting a specialist of occupational and environmental medicine may help to reveal the cause of poisoning. Furthermore, reporting to the public organization such as workers health center and Korea occupational safety and health is helpful to prevent additional injuries.

Septic arthritis is rarely caused by anaerobic bacteria, which is mostly secondary to hematogenous dissemination among the immunocompromised host. We report a patient of septic arthritis on the right knee joint caused by Bacteroides thetaiotaomicron. To the best of knowledge, this is the first report of septic arthritis caused by Bacteroides spp. in Korea.

Previous exposure to antimicrobials is a major risk factor for Clostridioides difficile infection (CDI). Antibiotic prescription and C. difficile toxin assay records of patients admitted to a tertiary hospital in Korea from 2009 to 2013 were collected to investigate the association between antibiotic consumption and CDI incidence. A Spearman's correlation analysis between CDI incidence (positive result of toxin assay/10,000 admissions) and antibiotic consumption (defined daily dose/1,000 patient-days) was performed on a monthly basis. Using the matched month approach, we found a significant correlation between CDI rate and moxifloxacin consumption (Spearman's r = 0.351, P < 0.001). Furthermore, using the onemonth delay approach, we found that the consumption of clindamycin (Spearman's r = 0.272, P = 0.037) and moxifloxacin (Spearman's r = 0.297, P = 0.022) was significantly correlated with CDI incidence. Extended-spectrum cephalosporins did not have any effect on CDI incidence.

Background: Clostridioides difficile infection (CDI) is one of the most common hospitalacquired infections, with its incidence and disease burden increasing markedly worldwide over the past decade. Methods: To assess the attributable costs of CDI in Korea, the expenses related to hospital management of CDI cases were computed. This analysis used data from the National Health Insurance Service–National Sample Cohort spanning a decade (2010–2019). The annual national burden of CDI was determined by combining the attributable cost per CDI case with the number of patients with CDI obtained from the Health Insurance Review and Assessment Service data. Results: The attributable costs of CDI were determined based on variations in the length of hospital stay and medical costs between patients with CDI and control patients. The mean length of hospital stay was significantly longer for patients with CDI than that for control patients: 43.06 vs. 14.76 days (a difference of 28.30 days, P < 0.001). The adjusted medical costs (2019 = 100) for cases of CDI and controls were 11,162 USD and 3,318 USD, respectively, with a significant difference of 7,843 USD (P < 0.001). The cost of CDI per case exhibited a noticeable annual increase from 2010 to 2019, despite an annual decreasing trend in length of hospital stay. The estimated national cost attributed to CDI was $28.9 million in 2010; however, it increased gradually each year, reaching $205.6 million in 2019 (a 600% increase over 10 years). Conclusion CDI is associated with substantial healthcare costs in Korea. The economic burden of CDI has gradually increased in South Korea.

BACKGROUND: Impairments of language function represent patients with Alzheimer's disease (AD) from the early stage and as the disease progresses the damage spreads over a much broader range of cognition and communicative functions. And, performances of the naming tasks in AD patients may reveal the gradual deterioration of their naming ability. METHODS: In this study, naming ability was studied in patients with questionable AD (CDR 0.5, n=10), mild AD (CDR 1, n=10), moderate AD (CDR 2, n=10) and 10 healthy controls matched for age, gender and educational level using confrontation naming and naming by verbal definition tasks. The purpose of present study was 1) to investigate whether the confrontation naming and naming by verbal definition in Alzheimer's disease is different depending on the severity, 2) to examine the effects of the syllabic cue on the two naming ability for the errors questions. RESULTS: The results from this study are as follow: 1) The two naming performances of the all AD groups were lower than those of normal people and showed significant difference. 2) There were differences between the two naming tasks, significantly lower performance on confrontation naming task than naming by verbal definition. 3) The effects of syllabic cue decreased gradually as severity progressed. 4) The effects of syllabic cue were no significant differences between the two naming tasks. CONCLUSIONS: The results suggest that anomia in patients with AD is due to various impairment including to lexico-semantic system, visual processing, phonological processing and auditory comprehension.

PURPOSE: Recently, the interest in positive psychotherapy is growing, which can help to encourage positive relationships and develop strengths of people. This study was conducted to investigate the effects of a positive psychotherapy program on positive affect, interpersonal relations, resilience, and mental health recovery in community-dwelling people with schizophrenia. METHODS: The research was conducted using a randomized control group pretest-posttest design. A total of 57 adults with schizophrenia participated in this study. The study participants in experimental group received a positive psychotherapy program (n=28) and the participants in control group received only the usual treatment in community centers (n=29). The positive psychotherapy program was provided for 5 weeks (of 10 sessions, held twice/week, for 60 minutes). The study outcomes included positive affect, interpersonal relations, resilience, and mental health recovery. The collected data were analyzed using repeated measures ANOVA for examining study hypothesis. RESULTS: Results showed that interpersonal relations (F=11.83, p=.001) and resilience (F=9.62, p=.003) significantly increased in the experimental group compared to the control group. Although experimental group showed a slight increase in positive affect, it was not significant. CONCLUSION: The study findings confirm that the positive psychotherapy program is effective for improving interpersonal relations and resilience of community-dwelling people with schizophrenia. Based on the findings, we believe that the positive psychotherapy program would be acceptable and helpful to improve recovery of mental health in schizophrenia.

BACKGROUND: The aims of the study are to investigate the present state of occupational health management (OHM) in small enterprises, to explore the related factors, and to provide the information for effective policy of OHM in those enterprises. METHODS: The study subjects were 155 small enterprises that had referred the measurement of workplace hazards to a hospital at the East Seoul, Korea. Self-administered questionnaire survey was conducted by Fax. The contents of the survey were present state of OHM and related factors. RESULTS: 1. The characteristics of OHM in charge were as follows; among the health manager (1) 81.9% had the high authority, (2) 63.2% could explain workplace hazard, (3) 52.9% had outside professional education, (4) 49.7% recognized the need for occupational health, and (5) 67.7% had pragmatic perspective on workers' health protection. 2. The occupational health activities that showed higher performance rate were as follows; periodic health examination (86.5%), measurement of workplace hazard (92.9%). The occupational health activities that showed lower performance rate were as follows; appointment of emergency hospital (26.5%), replacement health examination (18.1%), health education (30.0%), health promotion (23.3%), preparation of health statistics (14.8%), planning health management (9.7%) 3. As results of multiple logistic regression analysis, the factors associated with the higher activity of occupational health were longer duration(more than 5 years) of health manager in charge(OR=2.41), pragmatic perspective on workers' health protection (OR=3.79), experience of outside professional education (OR=2.40), repair of automobiles(OR=3.31), workplace that employed more than 10 workers (OR=4.02), history of workers' compensation (OR=8.05), employers' high concern (OR=4.61). CONCLUSION: These results suggest that interest of employers and appointment of suitable health manager in charge were important, and minimum regulations and the development of occupational health program integrated with promoting productivity are required to activate occupational health in small enterprise
