BACKGROUND: This study researched the relationship between shift work and one of its relevant health problems, functional gastrointestinal disorders. The study targeted nurses working at a university hospital, and compared the differences in gastrointestinal disorders of shift workers and non-shift workers and identified causes that significantly influence these symptoms. METHODS: In August 2013, a self-report survey was conducted on nurses working at a university hospital. Among those sent out, 1,201 responded and 851 were used for the final analysis. RESULTS: It was shown that the frequency of gastrointestinal disorders in shift workers was 1.881 times higher than that of non-shift workers. Factors that influenced gastrointestinal disorders included age, marital status, work duration, type of employment, job satisfaction, and perceived health status. Gastrointestinal disorders were seen more often with older age, being married, longer duration of employment, non-regular worker, low job satisfaction, bad perceived health status, and shift works. CONCLUSIONS: To prevent gastrointestinal disorders in nurses who work shifts, a health checkup system should be in place for clinical nurses who are of older age and have longer employment records. To decrease the causes of gastrointestinal disorders, campaigns suggesting regular diet and quitting alcohol use should be held consistently. Also, a category related to gastrointestinal disorders should be added to the employee health checkup for nurses with long work experience.

An autopsy case of spontaneous rupture of urinary bladder followed by longstanding chronic and acute hemorrhagic cystitis associated with anomalous course of the right ureter and pyo-hydronephrosis, and acutely disseminated tuberculous pneumonia in a twenty-two-year-old Korean Army soldier is presented. Pathogenesis of spontaneous rupture of urinary bladder is briefly discussed.

PURPOSE: This study is performed to help manage the metabolic syndrome in work place by identifying the effect on metabolic syndrome with subjects of Korean adult workers. METHODS: Using part of data of "The Fourth Korean National Health and Nutrition Examination survey 2nd year (2008)" which center for disease control is investigating. The general characteristics include age, educational level, occupation and marital status as factors affecting the metabolic syndrome of workers in this study. RESULTS: Work-related factors are the working environment in which they are working while they are pressed for time due to work status and overload. If the work status of worker is unpaid family member, the risk is increased by more than twice compared to paid workers. The risk for metabolic syndrome in work environment to work while fighting the clock is decreased compared to the work environment without time pressure. CONCLUSION: In order to manage the metabolic syndrome of workers, health promotion program to change management of both working condition and working environment can contribute to prevent the metabolic syndrome and ultimately prevent the cerebrocardiovascular diseases.

PURPOSE: Tissue Doppler Imaging(TDI) is a modern echocardiographic technique used for quantitative assessment of myocardial tissue velocities. The purpose of this study is to estimate the left ventricular function by TDI in Kawasaki disease(KD). METHODS: TDI and conventional echocardiography were performed in 33 patients(3.2+/-2.4 years) in acute phase, 33 patients(4.2+/-4.0 years) in subacute phase of KD and 60 children(5.4+/-3.9 years) in controls. Systolic velocity, systolic integral, E' velocity, E' integral, A' velocity and A' integral at the base, mid-septum and the apex were measured. Ejection fraction(EF) and myocardial performance index(MPI) were estimated by conventional echocardiography. Myocardial function was compared in KD patients of the acute and subacute phase with controls by TDI and conventional echocardiography. RESULTS: E' integral at the base(4.59+/-3.87 cm vs 6.91+/-4.29 cm, P<0.05), mid septum(3.52+/-3.13 cm vs 5.49+/-3.47 cm, P<0.05), apex(2.52+/-2.40 cm vs 3.80+/-2.48 cm, P<0.05), A' integral at the mid septum(1.24+/-1.19 cm vs 2.11+/-1.64 cm, P<0.05) and apex(1.14+/-1.32 cm vs 1.90+/-1.59 cm, P<0.05) were lower in the acute phase patients than in the controls. Systolic integral at base, mid septum and apex were significantly lower in KD patients of the acute phase than in the controls. There was significant negative correlation with right coronary artery diameter and systolic integral, E' integral, A' integral at mid septum, E' integral, A' integral at apex in the acute phase of KD. EF and MPI were not significantly decreased in KD. CONCLUSION: Myocardial velocity was not different, but systolic and diastolic integrals at the left ventricular septum were significantly decreased in the acute phase of KD by TDI. The data will need to be compared with febrile controls.

PURPOSE: The purpose of this study was to understand the present status of the work performance of the construction industry health managers and the developmental direction for the construction industry health management. METHODS: The subjects of this study were 149 health managers working in the construction industry. Data of a total of 130 participants were analyzed by excluding the missing data among field workers. The contents of the survey were the characteristics of the workplace, the difficulties and requirements of health management, and the level of job performance. RESULTS: The factors affecting measuring work environment task were age, number of workers, number of safety managers, and lack of support from the headquarters. The factors affecting managing work environment and physicochemical harmful factors were age, type of contract and conflicting business opinions. The factors affecting implementing health examination were age, type of contract, and number of safety managers. The factors affecting healthcare were age, type of contract, number of safety manager, presence of healthcare room, and conflicting business opinions. CONCLUSION: It is necessary to provide practical guidance and practical resources, and education for strengthening capacity. The support for business owners and managers support is needed.

PURPOSE: To evaluate accuracy of magnetic resonance(MR) imaging for staging of lung cancer and to compare the accuracies of CT and MRI. MATERIALS AND METHODS: We retrospectively analyzed 25 cases of lung cancer, which were confirmed surgically and pathologically. Five experienced radiologists participated in the receiver operating characteristic (ROC) analysis to evaluate and compare accuracies of the CT and MR imaging in preoperative staging of non small cell lung cancer by assessing tumor invasion of bronchus, mediastinum, chest wall, and hilar or mediastinal lymph node metastasis. Imaging results were evaluated against "truth" data based on both surgery and pathologic examination. RESULTS: Sensitivity of CT in distinguishing T3-T4 tumors was 60% ;specificity was 76%. These values for MR imaging were not significantly different(53% and 72%). With ROC analysis, no difference existed between accuracies of CT and MR imaging in diagnosis of bronchial involvement, but MR imaging was significantly more accurate than CT(p<0.05) in diagnosis of mediastinal invasion. There was no significant difference between accuracies of CT and MR imaging in detecting mediastinal node metastasis(N2 or N3); sensitivities were 64% and 78%, respectively, and specificities were 64% and 66%. CONCLUSION: There was no significant difference in accuracies of CT and MR imaging in preoperative tumor classification and assessment of mediastinal node metastasis, but MR imaging was more accurate than CT in assessment of mediastinal invasion.
