Objective: The aim of this study was to evaluate the correlation between the vertical position of maxillary first molar and vertical skeletal measurements in lateral cephalograms by using new linear measurements on the vertical axis of coordinates with calibration. Methods: The vertical position of maxillary first molar (U6-SN), and the conventionally used variables (ConV) and the newly derived linear variables (NwLin) for vertical skeletal patterns were measured in the lateral cephalograms of 103 Korean adults with normal occlusions. Pearson correlation analyses and multiple linear regression analyses were performed with and without calibration using the anterior and posterior cranial base (ACB and PCB, respectively) lengths to identify variables related to U6-SN. Results: The PCB-calibrated statistics showed the best power of explanation. ConV indicating skeletal hyperdivergency was significantly correlated with U6-SN.Six NwLin regarding the position of palatal plane were positively correlated with U6-SN. Each multiple linear regression analysis generated a two-variable model: sella and nasion to palatal plane. Among the three models, the PCBcalibrated model yielded highest adjusted R2 value, 0.880. Conclusions U6-SN could be determined by the vertical position of the maxilla, which could then be used to plan the amount of molar intrusion and estimate its clinical stability. Cephalometric calibration on the vertical axis of coordinates by using PCB for vertical linear measurements could strengthen the analysis itself.

The treatment gap can be defined as the difference between the proportion of people who have the disease and the proportion of those who receive proper treatment. The mental disorder treatment gap should be resolved because mental disorders have a substantial socioeconomic burden. This study examined the current status of the mental disorder treatment gap in Korea to identify the strategies to address it. The causes of the mental disorder treatment gap include a lack of human resources, a lack of financial resources, and low mental health literacy. To reduce the treatment gap, improving the medical fee of the psychiatric intervention, improving the quality of the assessment on the psychiatric residency training program, the provision of basic mental health services delivered by primary care physicians, the inclusion of classes on mental health in the school curricula, and the promotion of public’s mental health literacy through the active use of media should be considered. The present article is significant in that it proposed cost-effective measures by adding them to existing systems. The quantitative evaluation of mental health intervention is essential for these methods to be carried out effectively.

Melorheostosis is a rare type of sclerosing bone dysplasia with an incidence of approximately 0.9 per million individuals. This disease predominantly affects the appendicular skeleton, with rare involvement of the axial skeleton. Patients with spinal melorheostosis may present with symptoms such as scoliosis, stiffness, back pain, progressive myelopathy, radiculopathy, and vertebrobasilar insufficiency. Surgical management for spinal melorheostosis has been reported, but it remains exceedingly rare. Here, we present the case of a 67-year-old woman with incidental findings on thoracic vertebral imaging from a preoperative chest computed tomography scan performed for shoulder surgery. The patient had experienced gait disturbances and mild, motion-related back pain for approximately 2 to 3 years, along with a recent symptom of mild tingling sensations in both feet. A diagnosis of spinal melorheostosis was considered based on the characteristic imaging findings. In this case, rather than prioritizing the severity of the current symptoms, we focused on the location and extent of osteosclerotic lesions, which are directly associated with the potential development of neurological complications. Therefore, we opted for surgical treatment involving decompression and screw fixation. The patient’s symptoms were relieved without significant surgical complications over a 1-year follow-up period.

PURPOSE: This study was performed to obtain baseline information about the occupational and environmental medicine(OEM) residency programs in Korea. METHODS: We surveyed 39 residents for the present training condition, satisfaction, vision of OEM, the condition and satisfaction after residency programs by self- administered questionnaire. RESULTS: Residents want to get appropriate clinical and practical training to be a medical director in a factory or specialist of the occupational medicine based at a hospital. They report, however, that current system for OEM residency training program is not appropriate. The curricula, duration of the each curriculum, level of training hospital or institute need to be reconsidered. CONCLUSIONS: We need to develop more systematic residency program with support from government and OEM society.

OBJECTIVES: The prevalence of aged individuals in the Korean workforce continues to increase. This research determined the health and working conditions of Korean older wage workers and confirmed the effects of factors on the health-related quality of life of Korean older workers. METHODS: Of the 25,534 persons surveyed in the fifth Korea National Health and Nutrition Examination Survey, 1368 older (>55 years of age) wage workers without missing variables were selected. Their general characteristics, health status (cardiovascular disease, musculoskeletal disease, and mental health), working conditions (type of occupation, employment status, full- or part-time work, weekly average working hours, and shift work), and health-related quality of life assessed by the EQ-5D questionnaire were examined. RESULTS: The mean values of the EQ-5D index of the male and female older workers were 0.956 +/- 0.087 and 0.917 +/- 0.124, respectively (p < 0.001). The factors that caused statistically significant differences in the EQ-5D index for all subjects were age, education, household income, cerebro-cardiovascular event, osteoarthritis, musculoskeletal pain, stress, occupation type, employment status, and working hours. In logistic regression analysis, the factors that associated with perceived problems in each EQ-5D dimensions were age, musculoskeletal pain, stress, diabetes, smoking, occupation type, employment status, and working hours. CONCLUSIONS: To eventually raise the quality of life of older workers through health maintenance and management, it is necessary to manage related factors that include of musculoskeletal pain and diseases, stress, diabetes, smoking, occupation, employment status, and working hours.

BACKGROUND: Epoxy resin compounds are one of the common causes of occupational allergic contact dermatitis. In Korea, most cases of allergic contact dermatitis from epoxy resin compounds have been caused by the epoxy resin itself. We report a rare case of allergic contact dermatitis which was caused by epichlorohydrin, an ingredient of epoxy resin and 2,4,6-tris-(dimethylaminomethyl)phenol (tris-DMP), a kind of hardeners. CASE REPORT: A 43-year-old man, who had worked at the epoxy resin glue manufacturing factory since 1999, presented with mild and intermittent erythematous papules and rashes on his face, neck, trunk, and both arms. He was dealing with epoxy resin, epichlorohydrin, bisphenol A and hardeners. After a new hardener was added in August 2008, his skin lesions worsened from what he had experienced in the past. A skin patch test was performed to identify the causative chemicals of the skin lesion. Epichlorohydrin and tris-DMP elicited positive reactions after 48 hours and increased after 96 hours. CONCLUSION: This case confirmed occupational allergic contact dermatitis caused by epichlorohydrin and tris-DMP, an ingredient of epoxy resin and a hardener, respectively.
