Introduction: Preplacement health examination (PHE) is performed when a worker starts a certain work task which is designated as having occupational risks by the Ministry of Employment and Labor (MOEL). All data related to health examination except PHE are reported to the MOEL by the law. This study has been performed to understand the status of PHE at certain workplaces. Methods: PHE data gathered in a university hospital were analyzed and they were followed with results of the special health examination (SHE) in 2019 and 2020. Those who were evaluated as unfit to work as it was, were interviewed directly or indirectly through an occupational health manager to follow up the management status of their recognized health problems. Results: The unfit to work (unFTW) rate of PHE was 2.8%, and was not different according to the size of workplace or having occupational health service. The major cause of unfit to work was the uncontrolled life-style diseases such as hypertension and diabetes. The rate of SHE followed by PHE was 31.1%. It was not different by the unFTW rates, however, they were different according to having a full time in-house occupational health manager. Thirty-one among 71 examinees who were evaluated as unFTW underwent SHE after controlling their health condition and were finally evaluated as fit to work. Nineteen among 31 started to take medicine and eight have been placed in the work without designated risks. Conclusion: PHE can be used for new workers, who may have unknown or uncontrolled life-style diseases, to be asked to manage life-style diseases as well as work-related risks such as shift work. In order to have a better tracking system for work-related risks, the information of PHE should be analyzed together with other data from health examination.

Objective : Hydrocephalus after intracerebral hemorrhage (ICH) is known to be related to poor prognosis and mortality. We analyzed predictors of permanent hydrocephalus in the patients with surgically treated supratentorial ICH. Methods : From 2004 to 2019, a total of 414 patients with surgically treated primary supratentorial ICH were included. We retrospectively analyzed age, sex, preexisting hypertension and diabetes, location and volume of ICH, presence and severity of intraventricular hemorrhage (IVH), and type of surgery. Results : Forty patients (9.7%) required shunt surgery. Concomitant IVH was higher in the 'shunt required' group (92.5%) than in the 'shunt not required' group (67.9%) (p=0.001). IVH severity was worse in the 'shunt required' group (13.5 vs. 7.5, p=0.008). Craniectomy (47.5%) was significantly high in the 'shunt required' group. According to multivariable analysis, the presence of an IVH was 8.1 times more frequent and craniectomy was 8.6 times more frequent in the 'shunt required' group. In the comparison between craniotomy and craniectomy group, the presence of an IVH was related with a 3.9 times higher (p=0.033) possibility and craniectomies rather than craniotomies with a 7-times higher possibility of shunt surgery (p<0.001). Within the craniectomy group, an increase in the craniectomy area by 1 cm² was correlated with a 3.2% increase in the possibility of shunt surgery (odds ratio, 1.032; 95% confidence interval, 1.005-1.061; p=0.022). Conclusion : Presence of IVH, the severity of IVH and decompressive craniectomy were related to the development of shunt dependent hydrocephalus in the patients with ICH. The increasing size of craniectomy was related with increasing rate of shunt requirement.

Purpose: The purpose of this study was to identify the effects of health status and health management on activities of daily living (ADL) in older, urban-dwelling Koreans. Methods: A total of 206 subjects were recruited from one senior welfare center, six senior citizen centers, and subjects' home in two cities. Data was collected with self-reported questionnaires in order to measure health management, health status, and ADL. Data was analyzed by t-test, ANOVA, and stepwise multiple linear regression using SPSS/WIN 22.0. Results: ADL in this subject were different depending on their age, education, marital status, type of family, and average monthly living expenses. Multivariate analysis showed that age (${\beta}=-0.35$, p<.001), exercise ability (${\beta}=0.20$, p<.001), diabetes (${\beta}=-0.17$, p<.001), osteoarthritis (${\beta}=-0.15$, p<.001), caregiver (${\beta}=0.14$, p=.005), frequency of health management (${\beta}=-0.13$, p=.006), smoking (${\beta}=-0.11$, p=.019), hypertension (${\beta}=-0.10$, p=.027), and type of family (${\beta}=-0.10$, p=.036) were significantly associated with ADL. Overall, approximately 60.2% of total variability in ADL could be explained by the 11 variables in this model ($R^2=0.602$, F=32.06, p<.001). Conclusion: This study suggests that individualized health care should be continued for older, community-dwelling Koreans in order to improve their ADL. Moreover, we need to develop self-care programs and encourage them to participate in those programs.

Clinical observation was made on 210 cases of CVA that were confirmed through brain CT, MRI scan and clinical observation. They were hospitalized in the oriental medical hospital of Kyungwon University from January to December in 1998. Objective : To evaluate the current status of cerebrovascular disease in Korea, we performed observation on stroke patients. Methods : We performed a retrospective study on 210 cases of stroke who had been admitted to the Dept. of Internal Medicine, College of Oriental Medicine, Kyungwon University from Jan. 1, 1998 to Dec. 31, 1998. Results : The incidence was highest in the patients with the age of above fifty. The frequency of strokes was similar between male and female cases. Ischemic stroke(70.0%) was more common than hemorrhagic stroke(20.5%), with transient ischemic attacks(9.5%) occuring less frequently. Middle cerebra! arterial territory was the most commonly involved site in ischemic strokes. Among intracerebral hemorrhages, putaminal hemorrhages were found in 69.8%, and was followed by IVH(9.3%), IVH with ICH(7.0%), subcortical hemorrhages (4.7%) and pontine hemorrhages(4.7%). The most ordinary preceding disease was hypertension. The next was diabetes mellitus. Most cases were given simultaneous treatment in both western and oriental medical methods. Conclusions : Generally it is thought that CVA occurs frequently in winter. But our observations reveal no such relationship. The predisposing factors of cerebral infarction were usually initiated during the time of resting and sleeping and those of cerebral hemorrhage chiefly during the time of exercising. I Patients whose condition of consciousness was bad at the time of admission tended to have a bad prognosis. This study suggests changing trends of stroke in Korea, and that a multicenter prospective study using stroke registry is required for confirmation.

Background: Although dental implantation has become widespread and acceptable treatment for dental prosthodontics, maxillary posterior jaw region is often complicated by the pneumatization of the maxillary sinus and physiological resorption of the alveolar bone. When this occurs, the residual bone between the floor of the sinus and the crestal ridge is inadequate for the placement of implants. The sinus elevation procedure provides a way to increase the amount of available bone and to allow the placement of longer implants. Materials & methods: We studied 11 patients requiring the implant placements and the maxillary sinus elevation simultaneously from 1996 to 2003 in our clinic. Nine patients were males and two patients were females, aged from 39 to 72(mean=51.6). Four patients had medical compromised states; angina pectoris, diabetes, hypertension, hepatitis. Patients didn't show any pathologic findings clinically or radiographically. We studied the success and survival rate of implants, factors increasing the osseointegrating capacity of implants. Results: The success rate of osseointegration of implants was 93%. At least 6 months after loading on implants, the survival rate of implants was 78.5%. Autogenous bone graft and adequate residual bone height(>6mm) increased survival rate of implants. Conclusion: Successful implant placement with maxillary sinus elevation mainly depends on sufficient residual bone height, healthy maxillary sinus, autogenous bone graft.

Purpose: Drug overdose is easily found in the emergency department (ED). Sedative-hypnotics overdose causes the aspiration pneumonia in patients with decreased mental status. The purpose of this study was to investigate the risk factors of aspiration pneumonia in patients poisoned with sedative-hypnotics. Methods: One hundred seventy eight patients who were poisoned with sedative-hypnotics and who visited ED between 2009 and 2015 were included. This study was conducted retrospectively, with collection of data by review of medical records. We collected the data concerning the characteristics of patients and classified them into two groups based on the development of aspiration pneumonia. Logistic regression analysis was performed to investigate the factors for the development of aspiration pneumonia. Results: Thirty five patients had an aspiration pneumonia during their hospital stay in 178 patients. The age, amount of ingestion, Glasgow Coma Scale (GCS) score at admission, a history of hypertension and diabetes mellitus, and the hypotension at admission were significantly different between two groups in univariate analysis. The age, amount of ingestion and GCS score at admission were associated with the development of aspiration pneumonia in the multivariate logistic regression analysis (OR 1.028 (95%CI, 1.002-1.056, p=0.037), 1.026 (95%CI, 1.004-1.043, p=0.001), 0.737 (95%CI, 0.683-0.915, p=0.002)). All patients with aspiration pneumonia were discharged without a sequelae. Conclusion: The development of aspiration pneumonia in the patients of sedative-hypnotics overdose is associated with old age, amount of drug ingestion, and GCS score at admission.

The incidence of renal cell carcinoma (RCC) is high in Western and Northern Europe and North America, and low in Asia. Although the incidence of RCC in Japan is lower than the rates in the other industrialized countries, there is no doubt that it is increasing. In this paper, we would like to introduce the summary of findings of JACC study, which evaluate the risk factors for RCC in a Japanese population. JACC study suggests nine risk factors (i.e., smoking, obesity, low physical activity, hypertension, diabetes mellitus, kidney diseases, beef, fondness for fatty food and black tea) and one preventive factor (i.e., starchy roots such as taro, sweet potato and potato) in a Japanese population. In Japan, however, drinking black tea may be a surrogate for westernized dietary habits while eating starchy roots may be a surrogate for traditional Japanese dietary habits. Further studies may be needed to evaluate risk factors for RCC because the number of cases is small in our studies.

Obesity is associated with a number of pathological disorders such as non-insulin-dependent diabetes, hypertension, hyperlipidemia, and cardiovascular diseases. Bangpoongtongsungsankamibang (BTSK) has been widely used in the oriental medicine for the treatment of several diseases associated with inflammatory abnormalities in cardiovascular and nervous system. The BTSK is the modified prescription of Bangpoongtongsungsankamibang in which sea tangle (Laminaria japonica) were added. This study was carried out to detemine the anti-obestic effects of BTSK. Pretreatment with the BTSK at daily dose of 100 or 200 mg/kg (p.o.) far 4 weeks reduced serum triglyceride, total cholesterol contents in rat induced by Poloxamer-407 or Triton WR-1339, respectively. Furthermore, post-treatment with BTSK far four weeks also inhibited body weight gain, adipose tissue mass and hyperlipidemia induced by the high fat diet for six weeks. The BTSK shifted serum total-, HDL- and LDL-cholesterol levels toward the values of normal group, suggesting that BTSK has hypolipldemlc effects. The rats fed BTSK reduced lipid peroxide and hydroxy radical in the rat blood and increased superoxide dismutase (SOD) activity compared to the control group. Taken together, these results superoxide that BTSK improve hyperlidemia and obesity via the upregulation of anti-oxidative mechanism.

Obesity increases the risk of many adult diseases, such as atherosclerosis, diabetes, hypertension, ischemic heart disease and breast cancer. Inhibition of adipogenesis is an effective way in the anti-obesity management. Because of main components of Saururus chinensis is flavonoid, it has been showed some improvement by its antioxidant effects on the atherosclerosis, heart disease and diabetic hyperlipidemia. But mechanism of anti-obesity effect of S. chinensis is not clear. We investigated the effects of ethanol extracts of S. chinensis on adipogenesis in the 3T3-L1 pre-adipocyte. The 3T3-L1 cell line is commonly used to study adipogenesis in vitro. In this study, ethanol extracts of S. chinensis significantly decrease the lipid accumulation in the 3T3-L1 cells proved by measuring triglyceride contents and Oil red O staining. The proposed mechanism of inhibition of adipogenesis in the 3T3-L1 cells with ethanol extracts of S. chinensis is down-regulation of transcriptional factors and adipocyte-specific genes such CCAAT/enhancer binding protein ${\alpha}$ ($C/EBP{\alpha}$) and Peroxisome proliferator activated receptor ${\gamma}$ ($PPAR{\gamma}$) in concentration dependent pattern. These results suggest that ethanol extracts of S. chinensis inhibits adipognesis in the 3T3-L1 cells and can be used as a safe and efficient natural substance to manage anti-obesity.
