This study identified an effective control method for periodontitis by investigating the association between blood levels of vitamin D and periodontitis in Korean elderly based on raw data from the fifth Korea National Health & Nutrition Examination Survey of 2010 (KNHANES). In this study, 1,021 adults over 65 years of age were evaluated based on data from the KNHANES. Periodontal disease was assessed using community periodontal index (CPI), with CPI codes ≥3 defined as periodontitis. Blood levels of vitamin D were measured from blood samples and divided into four groups (first quartile: ≤13.23 ng/ml, second quartile: 13.24∼16.95 ng/ml, third quartile: 16.96∼21.58 ng/ml), and fourth quartile >21.59 ng/ml). Using multiple logistic regression analyses, the variables were adjusted for general characteristics, oral health-related characteristics, health-related characteristics, and bone mineral density. The statistical analysis was performed using the SAS (ver. 9.2). The results of this study are as follows: the prevalence of periodontitis was 42.6% in Korean elderly. After adjusting for general, oral health-related, and health-related, the risk of periodontitis in the first quartile group was 1.74 times (95% confidence interval [CI], 1.02∼2.98) higher than that of the fourth quartile group (p=0.041). After adjusting for general, oral health-related, and health-related characteristics as well as bone mineral density, the risk of periodontitis in the first quartile group was 1.73 times (95% CI, 1.02∼2.96) higher than that of the four quartile group (p=0.042). There was a significant relationship between blood vitamin D level and periodontitis in Korean elderly. For the prevention of periodontitis, factors related to vitamin D should be considered along with other risk factors.

This study was performed to assess the effect of one year's of meal service for home-staying urban elderly with low incole on their nutritional status. One hundred and eighty three subjects, who had already completed the first nutritional survey, were assigned to two group : meal served(served) and non-meal served(non-served). A meal containing approximately on half of the RDA for energy, protein, calcium and iron was served as lunch everyday to served group. After on year of meal service, follow-up-nutritional survey was done and changes of parameters were analyzed with paired t-test. Served female showed signficantly increased intake of riboflavin and calcium, while non-served female showed significantly decreased intake of calcium. Serum total protein, serum albumin and serum cholesterol were significantly increased in female regardless of meal service. Served remale was observed with significantly elevated LDL-cholesterol, whereas non-served female showed singnificantly lowered HDL-cholesterol. Significantly decreased serum iron, serum transferrin saturaion and significantly increased TIBC were observed for female regardless of meal service. But the proportion of anemic elderly according to Hb or serum iron was decreased more in served group. Female showed significantly increased serum zinc and copper regardless of meal service, whereas only served male showed significantly increased serum copper.

Primary ovarian pregnancy is one of the rerest types of extrauterine pregnancy. But an increase in the reported prevalence of ovarian pregnancies was published in recent years. Three cases of ovarian pregnancy which have Spiegelberg criteria are presented with a brief review of literatures.

Primary signet ring cell carcinoma of the prostate is extremely rare and about 18 cases have been reported in the literature. We report two cases of primary signet ring cell carcinoma of the prostate, arising in 79-year-old and 65-year-old men. Both cases were the poorly differentiated adenocarcinoma of the prostate with many signet ring cells. Signet ring cells were positive for prostatic specific antigen and prostatic acid phosphatase but negative for neutral and acid mucins. In summary, the signet ring cell carcinoma of the prostate is a rare variant of poorly differentiated adenocarcinoma of the prostate. The orgin of the prostate should be considered in cases of metastatic signet ring cell carcinoma, particularly when the signet ring cells are negative for neutral and acid mucins. Prostatic specific antigen and prostatic acid phosphatase should also be performed to confirm the primary signet ring cell carcinoma of the prostate.

PURPOSE: The incidence of urolithiasis has recently shown an increasing tendency in relation to improvements in living conditions in Korea. With the development of extracorporeal shock wave lithotriptor (ESWL), endourology and other new instruments, urolithiasis has become easier to treat, without surgical intervention. The incidence and treatment of urolithiasis, between the 1980 and 2000, were evaluated. MATERIALS AND METHODS: 328 and 1,142 patients with urolithiasis, either admitted between January 1981 and December 1984 or treated at the out-patient clinic between January 2001 and December 2004, respectively, were analyzed. RESULTS: In the early 1980s, 328 (27.3%) patients of the total 1,203 admitted to the urology department had urolithiasis. In the early 2000s, 1,142 patients were treated for urolithiasis. The total number and incidence constantly increased over the stated period. The ratio of males to females was 1.3:1 in the 1980s and 2.0:1 in the 2000s. The occurrence rate for those under 20 years decreased, but increased after the 6th decade. And the seasonal occurrence was highest during the summer of the early 1980s, but there was no seasonal difference during the early 2000s. The incidences of lower ureteral, bladder and urethral calculi were decreased, but those of renal and upper ureteral calculi increased. In the management of urolithiasis, open surgery and expectant therapy decreased during the 2000s. In the endourological management of urolithiasis, the success rates of ESWL, percutaneous nephrolithotomy (PNL) and ureteroscopic removal of stone (URS) were 94.5, 86.6 and 96.4%, respectively. CONCLUSIONS: The incidence and treatment modalities of urolithiasis have changed, especially since the late 1980s.

Objectives: This study aims to determine the influence of social exchange relationships, leader’s political skills, job stress, job satisfaction, and organizational commitment on turnover intention among dental hospital hygienists. Methods: A self-administrated questionnaire survey was conducted from April 1-May 12, 2020, involving 209 dental hospital hygienists in Seoul, Busan, and Gyeongnam. The collected data were analyzed using SPSS and AMOS statistical analysis programs. Results: In the hypotheses testing, 9 of 18 hypotheses were supported. In social exchange relationships, job stress, job satisfaction, and organizational commitment, the path to turnover intention had a significant effect, but it was not statistically significant in leader’s political skills. With regard to mediating effect, job stress, job satisfaction, and organizational commitment played a complete mediating role in the path from social exchange relationships to turnover intention. Conclusions To increase job satisfaction and organizational commitment, and lower job stress in order to have a positive impact on turnover intentions, it is imperative to develop and apply a program to enhance social exchange relationships.
