Purpose: We reviewed the cases of occupational diseases that occurred in healthcare workers from 2010 to 2019 and the cases of epidemiological investigations conducted by the Occupational Safety and Health Research Institute for them. Methods: In this study, gender, age, working period, occupational characteristics, and disease characteristics by occupation, which are general characteristics of healthcare workers approved for occupational diseases. In addition, 32 cases of epidemiological investigation of healthcare workers conducted by the Institute for Occupational Safety and Health for the past 10 years (2010~2019) were analyzed. Results: The gender, age, working period, occupational characteristics, and disease characteristics by occupation of medical workers recognized as occupational diseases were all statistically significant (p<.001). In the epidemiological investigation, ionizing radiation( 50.0%) and stress (33.3%) were recognized as disease-related factors, and even in cases of disapproval, ionizing radiation (60.0%) and shift work (25.5%) were designated as related factors. And it was statistically significant (p=.008). Conclusion The current study identified the types of diseases, various causes, and general characteristics and occupational characteristics that occur frequently in healthcare workers. Therefore, if this study is used as basic information to set the priority and direction of disease prevention project for healthcare workers, it is judged that it will be helpful in preventing industrial accidents.

Sulcus vocalis remains a surgical challenge despite many recent advances in laryngomicrosurgeries. We previously reported that 585-nm Pulsed dye laser (PDL) exerts favorable outcome in treatment of sulcus vocalis due to its therapeutic effects of collagen rearrangement and improved wound remodeling. In spite of the usefulness of PDL glottoplasty for treating sulcus vocalis, the device is no more available in the country. It prompted us to focus another angiolytic laser ; 532-nm KTP laser which has similar mechanisms of action and has been used for treatment of other laryngeal lesions elsewhere. Herein, we present a case of sulcus vocalis successfully treated with KTP laser. A patient underwent laryngomicrosurgery with angiolytic KTP laser (KTP glottoplasty) by the same surgical procedure with PDL glottoplasty. After the surgery, the patient presented improved voice outcome in time without complications.

OBJECTIVES: The objectives of this study were to evaluate the long-term effect of anti-platelet treatment on the radiological progression of collagen-induced arthritis in rats. METHODS: Female Lewis rats with collagen-induced arthritis were divided into three experimental groups: saline, aspirin monotherapy (n = 12), and aspirin–clopidogrel dual therapy (n = 12). Drugs were administered daily and continued up to 70 days after the induction of arthritis. The clinical arthritis index (weight, morphology score, and paw thickness) and radiological scores were evaluated. RESULTS: The clinical arthritis index peaked on day 20, while the radiological scores peaked on day 35. No intergroup difference was observed in the clinical arthritis index throughout the experiment. The aspirin–clopidogrel dual therapy group had a significantly higher mean radiological score than the other groups (p = 0.045) on day 35. Further treatments resulted in significantly improved radiological findings in the aspirin monotherapy and aspirin–clopidogrel dual therapy groups on day 70 but no significant improvement in the saline group. CONCLUSION: Anti-platelet agent treatment improved radiological findings on day 70. These observations emphasize the importance of a future long-term study of the effects of anti-platelet agent treatment on arthritis.
