The authors analyzed 28 cases with hypertensive cerebellar hemorrhage, diagnosed by computerized tomography(CT), between 1987 and 1990, in Chonbuk National University Hospital. The authors assessed the relationship of outcome to the CT appearance of the quadrigeminal cistern, which in some cases was obliterated by rostral displacement of the vermis resulting from the cerebellar mass. Obliteration of the quadrigeminal cisterns was classified on the CT scans into three grades:Normal(Grade I), Compressed(Grade II), or Absent(Grade III). There were 7 cases with Grade I, 9 with Grade II, and 12 with Grade II cisterns. Of the 28 cases, 6(85%) of those with Grade I, 7(78%) of those with Grade II, and none of those with Grade III cisterns respectively returned to their previous activities at 6 months or more after onset. A Grade I cisterns predicted a good outcome whether the hematoma was evacuated or not, as long as obstructive hydrocephalus, if present, was relieved early. However, a Grade II cistern was not predictive of a good outcome unless the hematoma was evacuated within 48 hours after onset of the hemorrhage. A Grade III cisterns predicted an unfavorable outcome. Taken together, these results strongly suggest that the CT grade of quadrigeminal cistern obliteration may be an indicator of outcome and may be useful in selecting treatment for patients with cerebellar hemorrhage.

Lung cancer is the leading cause of death from cancer and the most effective way to reduce lung cancer mortality is early detection and treatment. The low-dose computed tomography (CT) can reduce the chances of lung cancer death, and used as screening test in several countries. Pulmonary nodules are a common finding in smokers, and differential diagnosis from cancer is a particularly important in lung cancer screening in smokers. We tried to find out the characteristics of lung nodules in patients who underwent smoker cancer screening. Data on low-dose lung CT findings and smoking counseling were collected for lung cancer screening patients for smokers conducted from January 2012 to June 2022. Out of a total of 1,320 patients, 1,101 had lung nodules. Lung nodules located in the right upper lobe were the most common at 30.5%, and lung nodules located in the right middle lobe were the least at 11.5%. Solid nodules were 97.3%, and ground-lass shadowing lesion was 2.4%. The average nodule size was 3.33 mm, and the largest was 43 mm. Compared to the previous test, 8.8% of the nodules were changed, and 1.8% of the total were suspected of cancer. The number of cessation patients interviewed was 138 (10.5%), and 98 were referred to smoking cessation clinics. This study shows that the lung nodule reporting rate is higher than overseas lung nodule reporting rate.

BACKGROUND: Since the 1980s, restructuring, which includes downsizing, closures, mergers, and privatization, has expanded worldwide, and various studies have investigated its effect on health. However, previous studies have mainly focused on restructuring accompanied by massive lay-offs, and the effect of a merger on workers’ health is still controversial. This study aims to investigate changes in worker depression and job stress after a merger without downsizing, which is unusual in Korea. METHODS: Repeated surveys were done in April 2014, April 2015, and April 2016 involving the participation of 209 subjects. Participants were divided into two groups, which were comprised of blue-collar workers (104) and white-collar workers (105). Sociodemographic characteristics, including age, education level, job tenure, gender, marital status, smoking status, and alcohol consumption, were measured via a survey. To determine the level of depression, the Korean version of the Center for Epidemiologic Studies Depression Scale (CES-D) was employed, and to investigate job stress, the Korean Occupational Stress Scale-Short Form (KOSS-SF) was used. For statistical analyses, Pearson’s chi-square test, the Student’s t-test, and repeated measure analysis of variance (ANOVA) were performed. RESULTS: The results showed that depression (CES-D, F[2, 400] = 0.466, p = 0.628) was changed but without significance and job stress (KOSS-SF, F[1.899, 379.831] = 3.192, p = 0.045) were significantly different. The between-group difference in the CES-D score between the blue- and white-collar workers by survey administration time was not statistically significant (F = 0.316, p = 0.574). The interaction between the survey time and occupational group was also not statistically significant (F = 0.967, p = 0.381). The between-group difference in the KOSS-SF total score was not statistically significant (F = 1.132, p = 0.289), and the interaction between the survey administration time and occupational group was also not significant (F = 0.817, p = 0.437). In the job stress subgroup analyses Job insecurity and Lack of reward showed a significant difference by survey administration time. CONCLUSION: This study showed that a merger without massive downsizing can cause negative health effects such as an changes in depression and increase in job stress. To improve the health of workers, both the immediate negative effects on health, and the long-term effects or their resolution over time should be considered prior to the merger.

BACKGROUND: Periodic revision of assessment tools is essential to ensure risk assessment reliability and validity. Despite the recent revision of the Korea Occupational Safety and Health Agency (KOSHA) 2018, there is no evidence showing that the revision is superior to other cardio-cerebrovascular diseases (CVDs) risk-assessment tools for workplace health management. We conducted a comparative analysis using the Framingham risk score (FRS) as a gold standard to identify the most relevant CVDs risk-assessment tool for workplace health management. METHODS: We included 4,460 shipyard workers who had undergone a workers' health examination during January–December 2016. Risk levels for CVDs were calculated based on the FRS, KOSHA 2013, KOSHA 2017, KOSHA 2018 (2 methods), National Health Screening Program health risk appraisal (NHS HRA) 2017, and NHS HRA 2018. Study participants were categorized into low-risk, moderate-risk, or high-risk groups. Sensitivity, specificity, correlation, and agreement of each risk-assessment tool were calculated compared with the FRS as a gold standard. For statistical analyses, Spearman's rank correlation coefficient and the linearly weighted kappa coefficient were calculated. RESULTS: Sensitivity of the risk assessments was highest in the KOSHA 2018 (health risk appraisal [HRA]). The FRS showed correlation coefficients of 0.354 with the KOSHA 2013, 0.396 with the KOSHA 2017, 0.386 with the KOSHA 2018, 0.505 with the KOSHA 2018 (HRA), 0.288 with the NHS HRA 2017, and 0.622 with the NHS HRA 2018. Kappa values, calculated to examine the agreement in relation to the KOSHA 2013, KOSHA 2017, KOSHA 2018, KOSHA 2018 (HRA), NHS HRA 2017, and NHS HRA 2018 with the FRS, were 0.268, 0.322, 0.352, 0.136, 0.221, and 0.559, respectively. CONCLUSIONS: The NHS HRA 2018 risk calculation method is a useful risk-assessment tool for CVDs, but only when appropriate classification criteria are applied. In order to enhance the risk-group identification capability of the KOSHA guideline, we propose to apply the classification criteria set in this study based on the risk group definition of the 2018 Korean Society of Hypertension guidelines for the management of hypertension instead of the current classification criteria of the KOSHA 2018.
