PURPOSE: In this study, we attempted to analyze the occupational accident experience rate by working life cycle of Korean workers considering entrance and turnover in their jobs. The specific goal of this study was to calculate the accident experience rate according to workers' turnover history and previous accident experience. METHODS: We constructed a cumulative data set of 90,338 cases of workers' accident experiences in their jobs from the Fourth Korean Working Conditions Survey. The accident experience rates according to workers' turnover and previous accident experiences were analyzed using descriptive statistics and analysis of variance. RESULTS: In this study, the cumulative accident experience rate of Korean workers was found to be 5.2%. It was confirmed that the accident experience rate of workers increased as the turnover frequencies increased. In addition, we analyzed only the data of the workers who had experienced turnover and found that the accident experience rate after turnover increased about 7.5 times when workers had experienced accidents in the past. CONCLUSION: To prevent occupational accidents in workers, safety strategies should consider a worker's previous job history and injury experiences. It will also be necessary to focus preventive efforts on new and young workers through ongoing monitoring and on-the-job training.

PURPOSE: The aim of this study was to confirm the factors that affect the mortality associated with the open surgical repair of ruptured abdominal aortic aneurysm (rAAA) and to analyze the long-term survival rates. METHODS: A retrospective review was performed on a prospectively collected database that included 455 consecutive patients who underwent open surgical repair for AAA between January 2001 and December 2012. We divided our analysis into in-hospital and postdischarge periods and analyzed the risk factors that affected the long-term survival of rAAA patients. RESULTS: Of the 455 patients who were initially screened, 103 were rAAA patients, and 352 were non-rAAA (nAAA) patients. In the rAAA group, 25 patients (24.2%) died in the hospital and 78 were discharged. Long-term survival was significantly better in the nAAA group (P = 0.001). The 2-, 5-, and 10-year survival rates of the rAAA patients were 87%, 73.4%, and 54.1%, respectively. Age (hazard ratio [HR], 1.05; 95% confidence interval [CI], 1.02–.08; P < 0.001) and aneurysm rupture (HR, 1.96; 95% CI, 1.12–.44; P = 0.01) significantly affected long-term survival. CONCLUSION: Preoperative circulatory failure is the most common cause of death for in-hospital mortality of rAAA patients. After excluding patients who have died during the perioperative period, age is the only factor that affects the survival of rAAA patients.

PURPOSE: To investigate the pathways of radiation induced apoptosis and the effect of cysteamine (beta-mercaptoethylamine), as a radioprotector, on it. MATERIALS AND METHODS: HL-60 cells were assigned to control, irradiated, and cysteamine (1 mM, 10mM) pretreated groups, Irradiation was given in a single fraction of 10 Gy (6 MV x-ray) and cysteamine was administered 1 hour before irradiation. The activities of caspase-8 were measured in control and irradiated group to evaluate its relation to the radiation induced apoptosis. To evaluate the role of cysteamine in radiation induced apoptosis, the number of viable cells, the expression and activity of caspase-3, and the expression of poly (ADP-ribose) polymerase (PARP) were measured and compared after irradiation the HL-60 cells with cysteamine pretreatment or not. RESULTS: The intracellular caspase-8 activity, known to be related to the death receptor induced apoptosis, was not affected by irradiation (p>0.05). The number of viable cells began to decrease from 6 hours after irradiation (p>0.05), but the number of viable cells in 1 mM cysteamine pretreated group was not decreased afger irradiation and was similar to those in the control group. In caspase-3 analyses, known as apoptosis executioner, its expression was not different but its activity was increased by irradiation (p>0.05). However, this increase of activity was suppressed by the pretreatment of 1mM crysteamine. The cleavage of PARP, thought to be resulted from caspase-3 activation, occurred after irradiation, which was attenuated by the pretreatment of 1mM cysteamine. CONCLUSION: these results show that radiation induced apoptotic process is somewhat different from death receptor induced one and the pretreatment of 1 mM cysteamine has a tendency to decrease the radiation-induced apoptosis in HL-60 cells.

PURPOSE: This study aimed to identify the association between psychosocial work environment and depressive symptoms among Korean teachers. METHODS: Data on 235 elementary school teachers and 341 middle and high school teachers was obtained from the 2014 Korean Working Condition Survey. The effect of psychosocial work environment on depressive symptoms was determined by multiple logistic regression analyses. RESULTS: The prevalence of depressive symptoms was 18 % in elementary school teachers and 24 % in middle and high school teachers. When adjusted for demographics and other socio-psychological and environmental factors, ‘social community at work’ served as a protection factor for Korean teachers' depressive symptoms. In addition, ‘cognitive demands’ in elementary school teachers and ‘social support from supervisors’ in middle and high school teachers were found to be predictors of depressive symptoms. CONCLUSION: Interventions to increase ‘social community at work’ and ‘social support from supervisors’, and to decrease ‘cognitive demands’ may be helpful for Korean teachers at risk of depression.

A 19-year-old, woman who had been diagnosed as systemic lupus erythematosus (SLE) a year ago, was admitted because of fever, dizziness, and sustained postoperative bleeding after a hemorroidectomy. On admission, a CBC revealed pancytopenia (Hb 6.2 g/dL, WBC 1,200/microL, platelets 11,000/microL) with a shift to themicroLeft, and the FDP and D-dimer were positive. She was treated for sepsis and disseminated intravascular coagulation. Granulocyte colony-stimulating factor (G-CSF) was administrated twice for severe neutropenia. An increase in WBC and immature myeloid cells, mainly hypergranular promyelocytes on the peripheral blood followed and was considered to be the effect of G-CSF. To evaluate the cause of pulmonary infiltrates, bronchoalveolar lavage (BAL) was performed on the 5th day of admission. The BAL fluid revealed many promyelocytes and myelocytes with occasional structures recognized as Auer rods. Acute promyelocytic leukemia (APL) was confirmed on the bone marrow study and chromosome analysis. Unfortunately, the patient died of septic shock on the 9th day of admission. We report here a very rare case of APL diagnosed in a SLE patient, the diagnosis of which was somewhat delayed due to the use of G-CSF and superimposed sepsis.
