In order to study the exposure level of silica dust and the effects of silica dust on ventilatory function, respirable dust samples were collected by personal air samplers using NIOSH method 0500 from the selected foundry operations, and ventilatory function tests were performed on 209 male foundry workers and 239 male control subjects. Ventilatory indices such as forced vital capacity (FVC) , one-second forced expiratory volume (FEV1), ratio of FEV1 to FVC(FEV1 %), maximal mid-expiratory flow(MMF), peak expiratory flow rate (PEFR) and maximal expiratory flow at 25, 50 and 75 % of expired FVC (FEF25, FEF50, FEF75 were obtained by analyzing forced expiratory spirogram and maximal expiratory flow-volume curve which were simultaneously measured by Vitalography in standing position. The results were as follows : 1. The average quartz concentrations of respirable dust were the highest in melting operation (0.079 mg/m3) and followed by molding operation (0.051 mg/m3), finishing operation (0.041 mg/m3) and coremaking operation (0.023 mg/m3) in the descending order. 2. No significant differences for mean values of all ventilatory indices expressed as percent of predicted value were demonstrated between smokers and nonsmokers In foundry workers and control subjects. 3. Mean values of all ventilatory indices except FVC of foundry workers were significantly lower than those of control subjects. 4. Mean values of FEV1 %, MMF, FEF25, FEF50 and FEF75 expressed as percent of predicted value tended to decrease with increasing cumulative dust exposure. 5. In foundry workers, proportions of workers with low MMF, FEF50 and FEF75 were markedly higher than those with other indices, and were significantly increased with increasing cumulative dust exposure. 6. In foundry workers, 2 workers(1.0 %) were diagnosed as silicosis and the profusion of radiographic opacities were category 1/0 and q type. With the above considerations in mind, it suggested that increasing exposure of silica dust be associated with progressive deterioration in ventilatory function of an obstructive nature and that MMF, FEF50 and FEF75 be more sensitive indices in the detection of the early obstructive changes of air flow of workers exposed to silica dust.

Pulmonary endometriosis is a rare disease which is characterized by hemoptysis during menstruation (catamenial hemoptysis). We report a case of pulmonary endometriosis in a 33-year-old housewife. She has had regular menses with moderate flow and minimal dysmenorrhea. She had undergone curettage in May 1995 for artificial abortion. In July 1995, she experienced the first episode of hemoptysis. A chest CT scan revealed a 2.0 1.0 cm sized ill-defined soft tissue density in the periphery of anterior segment of the left upper lobe with a surrounding irregular ground-glass opacity. A left upper lobectomy was done under the diagnosis of pulmonary endometriosis. Cut section of the resected lung showed a round red-brownish solid lesion, measuring 2.0x1.0cm in cross. Microscopically a focus of the endometrial tissue, which was composed of endometrial glands and stroma, was found in the lung parenchyme and many hemosiderin laden macrophages were seen in the surrounding alveoli. The postoperative course was favorable with no further episodes of hemoptysis.

BACKGROUND: The purpose of this study was to identify the clinical and radiological outcomes of hook plate fixation for lateral end fracture of the clavicle and acromioclavicular dislocation. METHODS: There were a total of 20 cases with lateral end fracture of the clavicle and 16 cases with acromioclavicular dislocation. All patients were evaluated for range of motion, functional score by using Constant score, and American Shoulder and Elbow Surgeons shoulder index at just before implant removal and at final follow-up. Coracoclavicular distance was measured in acromioclavicular dislocation and bony union was evaluated in the lateral end fracture of the clavicle. RESULTS: The clinical outcomes and range of motion were increased at the final follow-up compared with just before implant removal in both the lateral end fracture of the clavicle and acromioclavicular dislocation. In acromioclavicular dislocation, all cases—except one—showed maintenance of reduction after implant removal. Moreover, in the lateral end fracture of the clavicle, all cases—except one—showed bony union. CONCLUSIONS: Hook plate fixation in the lateral end fracture of the clavicle and acromioclavicular dislocation resulted in good clinical and radiological results.

The cytochrome P450 (CYP) 3A subfamily is estimated to participate in the biotransformation of 50% of the currently prescribed drugs. Four members of the CYP3A subfamily have been identified in humans: CYP3A4, CYP3A5, CYP3A7, and CYP3A43. Initial data suggested that CYP3A5 accounts for only a small proportion of the total hepatic CYP3A in about 20% of samples, but it was later revealed that CYP3A5 represents more than 50% of the total CYP3A amount in some individuals. Several genetic variants have been described for the CYP3A5 gene, of which the CYP3A5*3 allele (gA6986G), the most common form and leading to the loss of CYP3A5 activity, has been extensively investigated in the aspect of pharmacokinetics and disease risk. This review summarized the molecular characteristics of the CYP3A5 gene, and discusses the association of the CYP3A5*3 polymorphism with disease risks such as cancer and hypertension, along with its role in the pharmacokinetics of CYP3A substrates.

PURPOSE: This study aimed to investigate the impact of nursing professionalism on the nursing performance and retention intention among psychiatric mental health nurses. METHODS: As a descriptive correlational study, this study sampled 206 psychiatric mental health nurses in six hospitals in Seoul and Gyeonggi area through convenience sampling. Data were collected from March 2 to 31, 2009 using a self-report questionnaire. The collected data were analyzed using SPSS WIN 16.0. RESULTS: In the subscales of professionalism, the 'Sense of calling' had the highest mean score while the 'Professional organization' had the lowest mean score. A significant positive correlation was observed in nursing professionalism, nursing performance and retention intention. According to an analysis on the impact of each subscale of nursing professionalism on nursing performance and retention intention, the 'Sense of calling' and 'Autonomy' were the most significant predictor variable. CONCLUSION: The results confirmed that the improvement of psychiatric mental health nurses' professionalism increases their nursing performance and retention intention and the 'Sense of calling' and 'Autonomy' are critical prediction factors. It is necessary to come up with a strategy which strengthens nursing professionalism in order to improve psychiatric mental health nurses' performance and retention intention.

PURPOSE: This study determined which obesity measurement correlates the best with diabetes and prediabetes. MATERIALS AND METHODS: This cross-sectional study enrolled 1603 subjects (611 men, 992 women; age 30-64 years) at the Cardiovascular and Metabolic Diseases Etiology Research Center. Body mass index, waist circumference, waist-height ratio, waist-hip ratio, waist-thigh ratio, and visceral fat were used as measures of obesity. Visceral fat was acquired using dual-energy X-ray absorptiometry (DXA). The prevalences of diabetes and prediabetes were defined using the criteria in the American Diabetes Association 2015 guidelines. RESULTS: After adjusting for age and other potential confounding factors, participants with a visceral fat mass in the upper 10th percentile had a higher odds ratio (OR) for diabetes and prediabetes than the upper 10th percentile of other adiposity indices [men, OR=15.9, 95% confidence interval (CI)=6.4-39.2; women, OR=6.9, 95% CI=3.5-13.7]. Visceral fat mass also had the highest area under the curve with diabetes and prediabetes in both men (0.69, 95% CI=0.64-0.73) and women (0.70, 95% CI=0.67-0.74) compared to other anthropometric measurements of obesity. CONCLUSION: Visceral fat mass measured using DXA is an indicator of diabetes or prediabetes, due to its ability to differentiate between abdominal visceral and subcutaneous fat.
