The health-related habits dietary behaviors and nutrient intakes of the elderly living in Cheongju were investigated by interviews with a questionnaire from August to September in 1996. The responses of 169 free-living elderly aged over 65(male 91, female 78) were analyzed. Thirty-six percent of the subjects smoked currently, 33%, drank alcoholic beverages, and 52% exercise regularly. Exercise was mostly in the from of walking for 1/2-1 hour. Significantly higher proportions of males smoked, drank, and exercised as compared to females. Food groups eaten at every meal were examined on a 5-point scale, and the consumption scores were compared with groups according to sex, age, smoking, drinking, and exercise habits. The elderly who exercised regularly got significantly higher scores in their calcium intakes and the variety of the 6 food groups than the elderly who did not exercise. The dietary assessment data showed that the energy intakes of males and females were 81.9% and 72.8% of the RDAs, respectively. The proportions of the elderly consuming less than 75% of RDAs of vitamin A and calcium were 96.5% and 91.1% of the total subjects, respectively. Higher educational status, more pocket money and regular exercise had positive effects on nutrient intakes, while smoking and drinking among females, but not males, had negative effects. Therefore, to improve nutritional status of the elderly, intake of vitamin A-and calcium-rich food such as milk with regular exercise should be emphasized on the education program.

The develop a simple screening test for identifying Korean elderly at risk of undernutrition, the data of the health-related habits, dietary behaviors and nutrient intakes of the elderly in Chongju were analyzed. Two risk indicators, mean adequacy ratio (MAR) and the respondents perceived health, were used to detect the undernutrition risk of the elderly. In order to select a list of questions for the test, factors a affecting nutritional status and items investigated in previous nutrition surveys of the elderly were considered, and 21 questions were primarily selected. A multiple regression and stepwise regression analysis were used to take out the weak predictors of poor nutrient intake, and to give item weights to the strong predictors, and a list of 17 questions was finally adopted. To determine the cut-point of the test score, sensitivity, and positive predictive values were calculated. The Simple Screening Test developed in this study is a brief, easily scored tool to predict poor nutrient intake and the perceived health status of the elderly. The test may provide a basis of further comprehensive nutritional assessment or intervention planning, if necessary, for those who are diagnosed ad "high risk". The test, however, needs to be independently validated by other groups of individuals.

The purpose of this study was to compare shear bonding strengths and debonding patterns of the ceramic brackets attached on the crystal which were grown on the enamel surface of a tooth with different concentrations of lithium sulphate-contained polyacrylic acid in different application times. Four kinds of concentrations of mixed solutions were made and applied to the enamel surface on extracted human premolars. The solutions were made by adding 0.3M or 0.6M of lithium sulfate to 50% or 65% of polyacrylic acid with 0.3M sulfuric acid. The solutions were applied for 30 or 60 seconds. After bonding, a universal testing machine was used to measure the shear bond strength, and then observations were made of debonding patterns through the stereoscope. And the enamel surface was observed through the scanning electron microscope to examine the pattern of crystal growth and debonding. The results were as follows: 1, Shear bond strength in the enamel surface treated with 50% polyacrylic acid was higher than that with 65% polyacrylic acid. 2. There were no statistical differences in shear bond strength according to concentration of lithium sulfate and application time of solutions. 3. Enamel surface was almost free of resin debris after debonding. 4. Enamel surface treated with 50% polyacrylic acid showed higher density of crystal growth than that with 65% polyacrylic acid under scanning electron microscope.

The study is designed as a systematic review on nonpharmacological interventions for patients with moderate to severe dementia. This review will be conducted in accordance with the Cochrane Handbook for Systematic Reviews of Interventions. The following databases will be searched: Cochrane CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, KoreaMED, KMbase, and KISS. The primary outcome will include the effect of the interventions on activities of daily living and behavioral and psychological symptoms of dementia. The literature search will be conducted based on search strategies designed for each database. The reviewers will independently assess the identified studies and extract the data. The risk of bias will be assessed and a meta-analysis will be conducted in accordance with the methodology for meta-analysis described in the Cochrane handbook. This systematic review will provide clinicians and policy makers with reliable evidence for developing and implementing nonpharmacological interventions for moderate to severe patients with dementia.

Endovascular treatment of isolated bilateral common iliac artery aneurysm (CIAA) requires salvage of at least one internal iliac artery to prevent complications such as ischemic buttock claudication. We treated a case of bilateral CIAAs using an internal iliac branched stent graft. We report a case of a 58-year-old man who presented with bilateral CIAAs. The left internal iliac artery was occluded with coil embolization. The right internal iliac artery was saved by using a branched stent graft. The aneurysms were excluded with conventional endovascular aneurysm repair. Completion angiography showed technical success. Follow up computed tomography angiogram at three months showed complete exclusion of bilateral CIAAs, no endoleaks, and patent right internal iliac artery. There was no pelvic ischemic complication. We treated successfully a case of isolated bilateral CIAAs using an iliac branched stent graft.

PURPOSE: Most urologists, to our knowledge, recommend prostatic biopsy if serum prostate specific antigen(PSA) concentrations are between 4 and 10ng/ml(gray zone), even in the abscence of abnormal digital rectal examination(DRE). But the detection of prostate cancer has not been frequent in patients with negative DRE and gray zone of serum PSA. So, we investigated the detection rate of prostate cancer to evaluate the effectiveness of biopsy, and provide the clinical data which is needed to make an appropriate guideline for management in those patients in Korea. MATERIALS AND METHODS: We retrospectively reviewed 58 patients with negative DRE and serum PSA greater than 4ng/ml, in whom transrectal systemic biopsy was done between January 1, 1996 and July 31, 1998. Additionally we analysed 38 patients with negative DRE and serum PSA more than 4ng/ml in a Korean literature. We calculated the detection rate of prostate cancer in patients with gray zone of serum PSA and serum PSA greater than 10ng/ml, respectively. RESULTS: Prostate cancer was detected in 5 patients out of the 58 patients(8.6%), including 1 patient(3.7%) out of 27 patients with gray zone of serum PSA and 4(12.9%) out of 31 patients with serum PSA greater than 10ng/ml. Prostate cancer was detected in 4 patients out of the 38 patients in the literature(10.5%), including 1 patient(5.0%) out of 20 patients with gray zone of serum and 3 patients(16.7%) out of 18 patients with serum PSA greater than 10ng/ml. Combining the results of our current study with that of other Korean literature, total number of patients was 96, and 9(9.4%) of them proved to harbor prostate cancer, including 2 patients(4.3%) out of 47 patients with gray zone of serum PSA and 7 patients(14.3%) out of 49 patients with serum PSA greater than 10ng/ml. CONCLUSIONS: The detection rate of prostate cancer in Korean with negative DRE and gray zone of serum PSA is significantly lower than that in North American. Therefore it may not be effective to perform biopsy in all of those patients in Korea. Needed are Korean criteria of prostatic biopsy to detect prostate carcinoma in those patients, which can be acceptable in Korean.

PURPOSE: To evaluate the beveled, full thickness astigmatic keratotomy. METHODS: This study included 185 eyes of 112 patients treated with beveled, full thickness astigmatic keratotomy. Treated eyes were divided into 3 groups: beveled, full thickness astigmatic keratotomy after implantable collamer lens (ICL) implantation (group A), beveled, full thickness astigmatic keratotomy after cataract surgery (group B) and beveled, full thickness astigmatic keratotomy alone (group C). Follow-up visits were at 1 week, 1 month, 3 months and 6 months. The outcome measures included uncorrected distance visual acuity, astigmatism, efficacy, safety and predictability. RESULTS: At 6 months postoperatively, astigmatism was significantly reduced: 68.9 +/- 18.24% in total, 69.24 +/- 20.76%, in the group A, 67.84 +/- 17.56% in the group B and 67.82 +/- 13.97% in the group C. The proportion of eyes with astigmatism 1.0 or less was 88.65% in total, 91.49% in the group A, 87.5% in the group B and 70.0% in the group C. Mean improvement in corrected distance visual acuity (CDVA) was 0.56 lines; no eyes lost 2 lines of CDVA after 6 months postoperatively. Postoperative complications were not observed. CONCLUSIONS: This study showed the beveled, full thickness astigmatic keratotomy is effective and safe for correcting astigmatism alone as well as correcting astigmatism after ICL implantation or cataract surgery.

PURPOSE: Our study aimed to examine the relationship between intelligence and health-related quality of life (HRQOL) in children (6-13 years old) diagnosed as having a brain tumor. MATERIALS AND METHODS: We administered a Korean version of the Wechsler Intelligence Scale for Children-III, the Pediatric Quality of Life Inventory, version 4.0 (PedsQL), the Korean version of the Parenting Stress Index-Short Form, and the Korean Version of the Parenting Sense of Competence (K-PSOC) scale before or after initial radiotherapy (T1) and after treatment termination (T2). In total, 13 patients completed both the T1 and T2 interviews. RESULTS: Scores significantly declined between T1 and T2 on the full-scale intelligence quotients (FIQ), verbal intelligence quotients (VIQ), performance intelligence quotients (PIQ), similarity and coding tests, as well as the K-PSOC, which measures parental anxiety. FIQ scores at T1 were correlated with the self-reported PedsQL total scores (r=0.739) and the parent proxy-report PedsQL scores for school functioning (r=0.706) at T2. Also, the FIQ scores at T2 were correlated with the self-reported PedsQL total scores (r=0.748) and scores for physical health (r=0.728) at T2. CONCLUSION: The cognitive ability and intelligence level of the patients significantly declined between on and off treatment periods, and higher intelligence functioning at both on and off treatment was correlated with long-term higher HRQOL. Further investigations that monitor intelligence, HRQOL and parenting stress over a longer period, using a greater number of participants, are needed.
