Purpose: This study was conducted to identify the job-related health problems of school teachers in Seoul area and investigate their disease management behavior. Methods: This study used the on-line survey to investigate frequent health problems and management behavior of teachers. And job-related diseases were identified using date from the National Health Insurance Corporation. Collected data were analyzed by descriptive statistics, t-test and ANOVA. Results: The frequent health problems of teachers were varicose veins, vocal cord disease and thyroid disease. And Job-related health diseases were varicose veins and vocal cord disease. These problems increased with career. 57.4% and 28.4% teachers in varicose veins and vocal cord disease did not do any management behavior to prevent or cure the disease. 56.8% teachers did not know how to prevent the diseases and 16.3% teachers did not practice even though they know the methods of prevention. Conclusion: Teacher's health examination should include varicose veins and vocal cord disease examination. And schools should try to offer various programs for preventing job-related health problems.

MIP was significantly increased in singers, compared to the untrained group. MIP in patients showed decreasing tendency compared to the untrained group, but were significantly lower than that in singers. MEP in singers was higher than that in the untrained group. MPT increased significantly in singers, but diminished in patients compared to the untrained group. MIP, MEP, and MPT in male singers were 50.8%, 61.0%, and 28.7 % higher than those in female singers. MIP, MEP, and MPT in the untrained male were more increased 32.3%, 25.0%, and 28.7%, respectively than those in the untrained female. There was no correlation between MPT and MIP or MEP. Regression analysis of the data set showed that weight and vocal cord dysfunction was a positive predictor of MPT. Factors affecting MIP were male, singers and weight. Factors affecting MEP were male, singers, vocal cord dysfunction and weight.

This study aimed to describe a rare case of gnathostomiasis in the vocal cord. A 54-yearold Chinese woman living in Korea visited with a chief complaint of voice change at the outpatient department of otorhinolaryngology in Hallym Sacred Heart Hospital, Hallym University on August 2, 2021. She had eaten raw conger a few weeks before the voice change developed, but her medical history and physical examinations demonstrated neither gastrointestinal symptoms nor other health problems. A round and red cystic lesion, recognized in the anterior part of the right vocal cord, was removed using forceps and scissors through laryngeal microsurgery. The histopathological specimen of the cyst revealed 3 cross-sections of a nematode larva in the lumen of the cyst wall composed of inflammatory cells and fibrotic tissues. They differ in diameter, from 190 ㎛ to 235 ㎛. They showed characteristic cuticular layers with tegumental spines, somatic muscle layers, and gastrointestinal tracts such as the esophagus and intestine. Notably, intestinal sections consisted of 27-28 lining cells containing 0-4 nuclei per cell. We tentatively identified the nematode larva recovered from the vocal cord cystic lesion as the thirdstage larva of Gnathostoma, probably G. nipponicum or G. hispidum, based on the sectional morphologies.

Objectives : Vocal cord paralysis(VCP) is a complex disorder which may result from numerous causes. We reviewed and analyzed the trend of clinical characteristics and causes of VCP in Korean patient. Method : A total 197 patients with VCP who visited St.Mary's hospital from March, 2000 to August, 2006 were reviewed retrospectively. They were analyzed according to sex, age, cause of VCP, position of paralyzed vocal fold, treatment methods. Results : The male and female ratio was 1.6 : 1. The unilateral paralyzed vocal fold was fixed at paramedian position in 84% of the cases. The left vocal fold was paralyzed about 2 1/2 times as much as the right vocal fold. Among the causes of VCP 30.9% of the cases were due to postoperative paralysis, and most of those were developed after lung, mediastinal surgery. laryngeal EMG was performed in 47 patients for determines the prognosis and treatment method. In the unilateral VCP, 90 patients were treated with injection laryngoplasty, 21 patients were performed thyroplasty type I. Conclusion : The causes of VCP include various diseases, so, detection of the primary disease is very important, because many fatal diseases are included among the primary diseases, and late detection can cause serious problems. VCP is not only a disease entity in itself, but can be seen as a sign of an underlying disease.

Background and Objectives Idiopathic unilateral vocal fold paralysis (IVFP) is believed to be due to inflammation and edema of the recurrent laryngeal nerve caused by viral diseases such as upper respiratory tract infections. Corticosteroid has a potent anti-inflammatory action which should minimize nerve damage. The purpose of this study was to investigate the effect of oral steroid therapy on IVFP. Materials and Method Study was performed for the IVFP patient from January 2012 to August 2017. Patient's dermography, direction and location of paralyzed vocal cords, history of hypertension, diabetes, cerebrovascular disease, and other underlying disease, smoking history, alcohol consumption and upper respiratory tract infection, and symptoms were investigated. Treatment was divided into three groups: the observation group, low-dose group, and high-dose group, and the recovery rate and time of vocal cord paralysis were analyzed in each group. Results Thirty-seven patients were enrolled in this study. There was no relationship between oral steroid use, dosage and recovery of vocal cord paralysis. Oral steroids showed a rapid recovery of vocal cord paralysis, but there was no statistically significant difference in the time of recovery of vocal palsy with or without steroids (p=0.673). In addition, there was no statistically significant difference in recovery rate between the period to start of treatment, presence of diabetes mellitus, and treatment modality, but the recovery rate was high in the group with upper respiratory tract infection history (p=0.041). Conclusion In IVFP, oral steroid therapy has no significant difference in time and extent of recovery compared to the case of spontaneous recovery.

Background： Unilateral vocal cord paralysis(UVCP) by recurrent laryngeal nerve injury is one of the common laryngological diseases. Objectives : We attempted to study the clinical feature and the causes of UVCP and also tried to investigate what is to be the initial approach for determining the causes of unknown-origin UVCP Materials and methods The charts of 82 patients with the diagnosis of UVCP were reviewed. The records were analyzed for patient's gender and age, the status of paralysed vocal cord, the crucial tests for the diagnosis, and the etiologies. Results : forty-nine(59.8%) male and 33(40.2%) female patients were included in this study. The age group of sixth decade was most commonly involved. Most of the cases showed paramedian position of palsy, and the left side(59.8%) was more frequently attacked. The most common cause of UVCP in this series was the unknown origin, followed by the surgical trauma and neoplasms. The etiologies of the six(12.5%) unknown-cause cases were found with the further evaluation, with the most useful test being a CT scan. Conclusion： Chest X-ray, esophagography, and CT scan should be included in the mandatory initial investigation of patients with unknown-origin UVCP
