Early recognition of coalescence in pneumoconiotic lesions is important because such coalescence is associated with the respiratory symptoms and deterioration of lung function. This complicated form of pneumoconiosis also has worse prognosis than does simple pneumoconiosis. High resolution computerized tomography(HRCT) provides significant additional information on the stage of the pneumoconiosis because it easily detects coalescence of nodules and emphysema that may not be apparent on the simple radiograph. The Purpose of this study is to clarify the role of HRCT in detection of large opacity and the relationship of change between the coalescence of nodules or emphysema and lung function in dust exposed workers. 1. There was good correlation between the HRCT grade of pneumoconiosis and ILO category of profusion. 5(9.09%) in 55 study population had confluent nodule extending over two or more cuts on HRCT. HRCT could identify the pneumoconiotic nodules which was not found by simple radiography in 6 workers with category 0/0. 2. No significant difference was observed coalescence of nodules and emphysema by dust type. 3. There was no significant difference in pulmonary function according to ILO and HRCT classification. 4. HRCT could detect the significant reduction in FEV1, FEV1/FVC, PEER, FEF25, FEF50, and FEF75 and remarkable increase in RV and TLC in study persons with emphysema compared with non-emphysema group. 5. Emphysema was found more often in nodules-coalescence group than small opacity group by HRCT. We found that HRCT could easily detect areas of coalescence and complicated emphysema compared to plain chest X-ray. Also our data suggest that it is primarily the degree of emphysema rather than the degree of pneumoconiosis that determines the level of pulmonary function.

Although malignant pericardial effusion is a common complication of malignancy, chylopericardium is a rare entity characterized by the accumulation of chylous fluid in the pericardial sac. The lymphatic vessels of the pericardium drain into the thoracic duct. The mechanical obstruction of venous drainage plays an important role in the pathophysiology of this disease. In most cases, pericardiocenthesis is needed to prevent cardiac tamponade. We present a case of a 15-year-old boy diagnosed as non-Hodgkin's lymphoma, diffuse large B cell, with superior vena cava syndrome, who developed an isolated chylopericardium after the first cycle of chemotherapy. We confirmed the diagnosis with an echocardiography, lymphangiography, and fluid analysis. Chylopericardium was managed successfully with pericardiocenthesis and drainage. If pericardial effusion were developed during the treatment of non-Hodgkin's lymphoma, chylopericardium should be considered as one of the differential diagnoses and associated venous thrombosis around the thoracic duct outlet should be ruled out.

BACKGROUND: Obesity not only does increase the incidence of breast cancer, but also affects the course of treatment, recurrence and mortality. This study aims to evaluate on the obesity status of Korean breast cancer survivors and their obesity-related lifestyles. METHODS: The study included 125 Korean female breast cancer survivors aged over 19 year old enrolled in the 2009-11 Korean National Health and Nutrition Examination Survey. Women who answered 'yes' to the question 'have you ever been diagnosed breast cancer by a physician?' was defined as a breast cancer survivors. Height, weight, and waist circumference were measured and Body mass index (BMI) was calculated. Body fat percent was assessed by dual X-ray absorptiometry (DXA). Standardized surveys by trained interviewers were used to investigate survivors' obesity-related lifestyles such as physical activities, sleeping hours and nutrients intake. RESULTS: 48.4% of Korean breast cancer survivors were obese. 44.7% had abdominal obesity and 89.2% had body fat percent over 30. Their physical activity level was generally low; only 22.5% maintained health-enhancing level of physical activities. Fat intake (14.4 [0.8] %) was as low and carbohydrate intake (74.2 [1.2] %) was high. However, daily dietary fiber intake was low (10.5 [1.1] g). Factors that were found to be significantly related with obesity in Korean breast cancer survivors were low education level (P=0.042), smoking (P<0.001), having chronic diseases (P=0.002) and short sleeping hours (P<0.001). CONCLUSIONS: It is mandatory for physician to evaluate obesity status of breast cancer survivors as soon as their diagnosis and give proper intervention to maintain healthy weight and healthy obesity related lifestyle.

Gastrointestinal system involvement is one of the principal complications seen in the recipients of hematopoietic stem cell transplantation (HSCT), and it is also a major cause of morbidity and death in these patients. The major gastrointestinal complications include typhlitis (neutropenic enterocolitis), pseudomembranous enterocolitis, viral enteritis, graft-versus-host disease, benign pneumatosis intestinalis, intestinal thrombotic microangiopathy, and post-transplantation lymphoproliferative disease. As these patients present with nonspecific abdominal symptoms, evaluation with using such imaging modalities as ultrasonography and CT is essential in order to assess the extent of gastrointestinal involvement and to diagnose these complications. We present here a pictorial review of the imaging features and other factors involved in the diagnosis of these gastrointestinal complications in pediatric HSCT recipients.

OBJECTIVES: Clozapine is a widely prescribed antipsychotic drug for schizophrenia and is known to increase the risk of cardiovascular disease due to its metabolic side effects. However, little is known about the effect of clozapine on the platelet activation, another important factor in the development of cardiovascular disease. In this study, we tried to investigate the effect of clozapine on platelet activity in patients with schizophrenia by comparing the mean platelet component (MPC) values before and after the clozapine administration. METHODS: A retrospective review of medical records of patients with schizophrenia, who newly started clozapine treatment from September 1st, 2003 to April 30th, 2007 at the Department of Psychiatry, Konyang University Hospital in Republic of Korea was performed. The final statistical analysis included 14 participants. Bayer ADVIA 120® system was used to measure MPC. RESULTS: Among the 14 participants, five subjects were males (28.60%), and ten subjects were females (71.40%). The mean age of participants was 37.50±11.64 years. Average of duration of illness was 91.00±93.96 months, with the mean dosage of clozapine taken by participants at the time of the last blood test was 337.50±109.52 mg. The mean MPC measurement before and after receiving clozapine was 26.12±2.22 g/dL and 25.14±2.08 g/dL respectively. Wilcoxon signed rank test showed that there was a statistically significant decrease in MPC levels after clozapine administration (V=16, p=0.024). CONCLUSIONS: Decreased MPC levels after clozapine administration implies that clozapine may increase platelet activation which could have an adverse effect on the occurrence of thromboembolic disease. Our findings also suggest that careful monitoring of the risk factors of cardiovascular diseases, such as platelets activity, is necessary when administering clozapine.

Korean Journal of Occupational Health Nursing 2021;30(3):110-119
Purpose:
The purpose of this study was to explore the factors affecting turnover intention of nurse who work in comprehensive nursing care service wards.
Methods:
The study design was a cross-sectional study. We recruited participants in 5 general hospitals located in Gyeonggi. Data were collected using structured questionnaires. Data of 150 nurses were included in the final analysis. Multiple regression analysis was used to identify the influencing factors on turnover intention.
Results:
Work in the thoracic surgery department (β=.158, p=.045), Emotional labor (β=.282, p=.004), occupational stress (β=.222, p=.004), and burnout (β=.249, p=.003) were identified as factors influencing turnover intention. These factors explained 39.1% of the variance of turnover intention.
Conclusion
The findings suggest that it is important to reduce emotional labor and occupational stress to reduce turnover intention for nurse in comprehensive nursing care service wards.

Synovial sarcoma is a malignant soft tissue neoplasm that develops mainly in para-articular locations in the extremities, but can arise in a wide variety of other sites. Primary breast synovial sarcoma has been reported infrequently worldwide. We report the case of 15-year-old female who was diagnosed with primary breast synovial sarcoma. We performed wide excision for the breast mass. However, local recurrence was detected 9 months later. We performed wide excision for the recurrent breast tumor. After 27 months, a solitary metastasis was found in the right upper lobe of the lung. We performed wedge resection for the lung mass and treated her with palliative chemotherapy using doxorubicin and ifosfamide. Twenty-eight months after chemotherapy, she is alive without evidence of recurrence. We report the details of this case along with a review of the literature.

BACKGROUND: Previous studies have examined the association between alcohol consumption and metabolic syndrome (MetS) in adults, but studies in the elderly are lacking. We examined the relationship between high-risk alcohol consumption and MetS in elderly Korean men using the Alcohol Use Disorders Identification Test (AUDIT) questionnaire from the 2010–2012 Korean National Health and Nutrition Examination Survey. METHODS: Among 25,534 subjects, 2,807 were men >60 years of age; after exclusions, we included 2,088 men in the final analysis. We categorized the study participants into three groups according to AUDIT score: low risk (0–7), intermediate risk (8–14), and high risk (≥15 points). RESULTS: Among the study population, 17.0% of the men were high-risk drinkers, who had the highest mean waist circumference, systolic and diastolic blood pressure (BP), fasting plasma glucose (FPG), and triglyceride (TG) levels. The overall prevalence of MetS was 41.9% in the elderly men, and it was significantly higher in the group with high (48.3%) versus low (31.9%) AUDIT scores. The prevalence of MetS components (elevated BP, high FPG, high TG, and low high-density lipoprotein cholesterol) was associated with a high AUDIT score. The odds ratios (95% confidence interval) of the high-risk group for MetS, elevated BP, and high TG were 1.40 (1.03–1.89), 1.82 (1.28–2.60), and 1.77 (1.30–2.41) after adjustment for confounding variables. CONCLUSION: AUDIT score was correlated with most MetS components in elderly Korean men.

BACKGROUND: Marital status is as an important sociodemographic variable for health studies. We assessed the association between marital status and health behavior in middle-aged Korean adults. METHODS: This is a cross-sectional study of 2,522 Korean middle-aged adults (1,049 men, 1,473 women) from the 2010 Korean National Health and Nutrition Examination Survey. The subjects were classified as living with a partner or living without a partner (never married, separated, widowed, and divorced). We assessed the relationship between marital status and five health behaviors (smoking, high-risk alcohol intake, regular exercise, regular breakfast consumption, and undergoing periodic health screening). RESULTS: Age, income level, educational level, and occupational classification were all significantly associated with marital status. The risk of undergoing health screening (odds ratio [OR], 0.53; 95% confidence interval [CI], 0.32 to 0.90) and having regular breakfast (OR, 0.50; 95% CI, 0.27 to 0.92) were significantly lower in men living without a partner than with a partner. Women living without a partner had a higher smoking risk (OR, 2.27; 95% CI, 1.09 to 4.73) and a higher risk of high-risk alcohol consumption (OR, 5.33; 95% CI, 1.65 to 17.24) than their counterparts. CONCLUSION: Korean middle-aged adults living with partners are more likely to have healthier behavior than living without a partner. The association between marital status and health behaviors differed by sex.
