Authors reviewed clinical records of 92 patients with tetanus from January 1974 to December 1983 at Severance Hospital and the following results wre obtained. 1) There were about 2.2 times more cases of neonatal tetanus than that of nonneonatal. The admitted cases of tetanus decreased in 1980's compared to those of 1970's. 2) The male versus female ratio was 3 : 1 not only in nonneonatal but also in neonatal teanus. 3) There was a tendency of higher mortality when the site of injury was on the central part of the body than on the distal. 4) Most cases of tetanus developed after the injury with bactrial contamination as expected, but a few cases are due to only trivial injury such as acupuncture or injection without overt contamination. 5) There was a close relationship between the incubation period and mortality in neonatal tetaus but no such definite relationship in nonneonatal tetaus. 6) The duraton of admission was about 3 weeks and the majority of deaths occureed in less than one week of admission. 7) There was no statistically significant difference in mortality between the group who used tetanus antitoxin from animal and that who used human tetanus immuneglobulin.

OBJECTIVE: The purpose of this study was to develop the decision tree models to classify the characteristics of those who had not undergone the health screening tests provided by the National Health Insurance Corporation. METHODS: Total of 5,102,761 subjects of health screening services in the year of 2002 was used. The data was divided into two data-sets (disease VS. non-disease group). The target variable was whether they took the health screening services. The number of input variables was 25 in total. RESULTS: The decision trees were classified into fourteen different types of non-examinees in the non-disease group and nineteen in the disease group. The ROC curve areas in the non-disease and disease groups were .761 and .714, respectively. CONCLUSION: The different types of non-examinees classified by the decision tree models would facilitate the foundation for the further analysis of individual characteristics and the effective health screening service management in future.

Objectives: This study analyzed risk factors for suicidal ideation in South Koreans from a life cycle perspective. Methods: A secondary analysis was conducted of data collected in 2015 as part of the 6th Korea National Health and Nutrition Examination Survey (KNHANES). The participants comprised 5,935 individuals aged 12 years or older. The statistical analysis reflected the complex sampling design of the KNHANES, and the Rao-Scott chi-square test and multiple logistic regression analysis were performed. Results: The prevalence of suicidal ideation was 5.7% in adolescents, 3.7% in young adults, 5.4% in middle-aged adults, and 7.0% in older adults. Depression and stress were risk factors in every stage of the life cycle. In those aged 12 to 19 years, activity restrictions were significantly associated with suicidal ideation. Education and subjective health status were risk factors in adults aged 20 to 39 years, and education, activity restrictions, and quality of life were the major risk factors in those aged 40 to 64 years. For adults 65 years of age or older, the risk of suicidal ideation was higher among those with inappropriate sleep time. Conclusion The risk factors for suicidal ideation were found to be different across stages of the life cycle. This suggests a need for individualized suicide prevention plans and specific government policies that reflect the characteristics of each life cycle stage.

The giant intra-articular osteochondroma of the knee is very rare and is probably result of synovial metaplasia of the fibrous capsule or of the adjacent connencive tissue of a joint, and of the fragment of articular cartilage. The gross findings and histology are consistent with the osteochondroma. The authors experienced a case of giant intra-articular osteochondroma of the right knee in a 19 years old man who had history of knee injury when he was 16 years old. The mass was excised and the symptome was relieved.

Background: Inter1eukin-6(IL-6) is known to be produced by osteoblastic cells and to have impartant role in regulation of bone remodelling, Most previous studies indicated that IL-6 bas a major role in stimulating osteoclastic resorption by increasing recruitment and proliferation of preosteoclasts. But its autocrine effect on osteoblastic cells has not been well established yet. Therefore, we studied the effects of IL-6 on messenger RNA (mRNA) expression of proteins that are characteristic of osteoblastic cells in human bone marrow stromal (osteoprogenitor) cells (hRMSC). Methods: The expression of mRNAs for alkaline phosphatase, al(1)-collagen, osteopontin and decorin were studied by northern blot analysis after 3 7 days' treatrnent with IL-6 in the concenttation range of 101,000 U/ml. Results: The mRNA levels for any of the osteoblastic proteins studied did not change significantly by IL-6 treatment up to the concentration of 1,000 U/ml. Conclusion: These results suggest that IL-6 does not have a significant role in differentiatian or activities of human bone rnarrow stromal.

OBJECTIVES: To assess the association between the occurrence of cerebrovascular disorders and a medication adherence in diabetes mellitus patients. METHODS: Medical records from 1,114 new patients with diabetes mellitus were collected and the occurrence of cerebrovascular disorders was observed. Data was gathered from the health examination records of diabetes mellitus patients registered at the Korean Metabolic Syndrome Research from 1996 to 2005, medication records from the National Health Insurance Corporation and death data from the National Statistics Office from 1997 to 2007. Hazard ratios were analyzed using the Cox proportional hazard model to test the association between the occurrence of cerebrovascular disorders and the level of medication adherence. Medication adherence was calculated using Continuous measure of Medication Acquisition (CMA). RESULTS: Of 1,114 diabetes mellitus patients, cerebrovascular disorders occurred in 67 cases (6.1%). The mean duration for the development of a cerebrovascular disorder was 3.82 yr. Medication adherence (> or =0.8 vs. <0.5: HR, 3.26; 95% CI, 1.47-7.21, > or =0.8 vs. 0.5-0.7 HR, 0.99; 95% CI, 0.33-2.95) was an independent factor associated with the occurrence of cerebrovascular disorders in diabetes mellitus. CONCLUSION: Increased medication adherence is necessary to prevent the occurrence of cerebrovascular disorders in diabetes mellitus patients. Furthermore we propose that CMA be considered as a method for monitoring medication adherence in clinics.

The expression of two cell proliferation indices, the proliferating cell nuclear antigen( PCNA), using the monoclonal antibody in the immunoperoxidase method, and the nucleolar organizer regions (NORs), using silver nitrate staining technique, were assessed in formalin-fixed paraffin embedded material of transitional cell urinary bladder carcinomas. The aim of our study was to examine comparatively the expression of PCNA and the number of NORs in 37 transitional cell bladder carcinomas and to investigate how they correlate with tumor grade and the disease stage. It was noticed that the PCNA expression rate(%) related to grade was statistically significant only between grades II and III (p<0.05), while that between grades I and II was not statistically significant(p > 0.05). The mean number of AgNORs per nucleus between grades I and II and between grades II and III were statistically significant(p<0.05). As far as the correlation of PCNA expression rate(%) with the stage is concerned, PCNA expression rate (%) was higher in the invasive tumors(p<0.05) than in the superficial tumors and AgNOR Numbers was also greater in the invasive tumors(p <0.05). The linear correlation coefficient between PCNA expression rate (%) and AgNOR counts was 0.52(p <0.001) In conclusion, a considerable relationship was found between the histological grade and each of the two indices used. A good correlation was also demonstrated between each of PCNA expression rate(%) and AgNOR scores to the pathologic stage. Our results suggest that PCNA expressionrate( % ) and AgNOR scores may be prognostic induces in urinary bladder cancer.

PURPOSE: To determine the prognostic and predictive value of liver volume in colorectal cancer patients with unresectable liver metastases. MATERIALS AND METHODS: Sixteen patients received whole liver radiotherapy (WLRT) between January 1997 and June 2013. A total dose of 21 Gy was delivered in 7 fractions. RESULTS: The median survival time after WLRT was 9 weeks. In univariate analysis, performance status, serum albumin and total bilirubin level, liver volume and extrahepatic metastases were associated with survival. The mean liver volume was significantly different between subgroups with and without pain relief (3,097 and 4,739 mL, respectively; p = 0.002). CONCLUSION: A larger liver volume is a poor prognostic factor for survival and also a negative predictive factor for response to WLRT. If patients who are referred for WLRT have large liver volume, they should be informed of the poor prognosis and should be closely observed during and after WLRT.

PURPOSE: To assess the efficacy and safety of selective laser trabeculoplasty (SLT) as initial and adjunctive treatment for ocular hypertension and open angle glaucoma. METHODS: Twenty-four eyes with ocular hypertension and 63 eyes with open angle glaucoma were treated with a frequency-doubled, Q-switched Nd:YAG laser. Intraocular pressure (IOP) was measured prelaser treatment, one week, one, two, three, six, 12, 18, and 24 months after treatment. RESULTS: The average pre-laser IOP of 87 eyes was 21.6 mmHg. The mean IOP percent reductions at 1 week, one, two, three, six, 12, 18, and 24 months were 15.3%, 20.0%, 21.3%, 19.6%, 23.4%, 23.4%, 20.5%, and 20.9%, respectively. The IOP percent reductions in the initial treatment group at one, 12, and 24 months were 21.1%, 24.8%, and 22.8% respectively. The IOP percent reductions in the adjunctive treatment group at 1, 12, and 24 months were 19.6%, 22.9%, and 20.2% respectively. There were no differences in IOP percent reduction between the initial treatment group and the adjunctive treatment group. CONCLUSIONS: Selective laser trabeculoplasty has shown reasonable efficacy in lowering IOP over two-year follow-up period as initial and adjunctive treatment for ocular hypertension and open angle glaucoma.
