BACKGROUND: Osteoporosis is the most common metabolic bone disorder. Osteoporosis has emerged as a leading public health problem with elderly persons and its detection is important for prevention and treatment of fracture. this population-based study was conducted to evaluate the prevalence and risk factors of osteoporosis in the elderly women. METHODS: One hundred thirty eight women aged 60 years or older in rural area were investigated with questionnaires and measurements of height, weight. Bone mineral density(BMD) measurements of lumbar spine and femoral neck were made with dual energy X-ray absorptiometry(DEXA). The World Health Organization criteria for diagnosis of osteoporosis using the manufacturer's young adult population mean and our study young population mean have been applied. Our study's young adult population mean was derived using normal premenopausal 37 women aged 30~45 years. RESULTS: The prevalence of osteoporosis was 45.7% for lumbar spine, 13.0% for femoral neck by the manufacture's young adult mean and 63.0% and 34.8% by our study young adult population mean, respectively. Weight and smoking were associated with lumbar spine BMD. Age was associated with femoral neck BMD. CONCLUSION: Our data suggest that the prevalence of osteoporosis is dependant on reference population mean and measurement site.

PURPOSE: For medical students to have a meaningful learning experience, the curriculum must integrate what students are learning in class with the skills and knowledge required in the clinicalsetting. To satisfy these needs, an integrated curriculum (IC) has been operating at Chonnam National University Medical School since 1999. The purpose of this study was to evaluate the changes in IC students during two implementation periods, the first in 2001 and the second in 2004. This study focused on the student viewpointin order to create an authentic IC program. METHODS: Questionnaires were used to evaluate the differences in the student perception of IC. The content of the questionnaire dealt with the appropriateness of time management, coherence of the content, teachinglearning method, and IC evaluation. RESULTS: There were positive responses from the second implementation period than from the first, for almost all sub-items. However, the results showed that IC has to be reinforced by instructors teaching a coherentcontent, by using a variety of teaching-learning methods, by having the students participate actively, and by offering holistic and integrated assessments. CONCLUSION: The following three steps are recommended for the improvement of IC: facilitate an IC committee, develop teaching-learning methods, and guide student participation.

OBJECTIVES: Dementia has emerged as a leading public health problem in elderly persons, and its early detection is important for the treatment of curable cases, and in the educational support for other family members. Although dementia screening tests are available, they have not gained widespread use in community or primary care settings. Our goal was to validate the Time and Change (T and C) Test, -including its validity and reliability in patients, and to assess it as a simple, standardized method for the screening of dementia in the rural elderly. METHODS: The participants in this study comprised of 59 patients from an urban hospital and 405 persons from a rural community aged 65 years or older. The time test evaluated the understanding of clock hands indicating 11: 10, and the change test the ability to make 1, 000 Won from a group of coins, consisting of one 500, seven 100, and seven 50 Won coins. The T and C ratings were validated against a reference standard based on the physician? diagnosis of the patients. The convergent validity in relation to other cognitive measure, test-retest agreement, and inter-observer reliability were assessed. To assess the relationship between the Korean Mini-Mental State Exam (K-MMSE) and the T and C Test, the mean K-MMSE scores were compared with the results of the T and C Test in the elderly from a rural community. RESULTS: The T and C Test had a sensitivity and specificity of 73.0, and 90.9%, and positive and negative predictive values of 93.1, and 66.7%, respectively. The test-retest and inter-observer agreement rates were both 95%. The K-MMSE scores and T and C Test were significantly related in the elderly from a rural community (p< 0.01). The T and C Test was not influenced by the educational status. The Time and Change Tests took a mean of 6.3 and 12.7 seconds, respectively, to complete. CONCLUSION: The T and C Test is a simple, accurate and reliable, performance-based tool in the screening for dementia. Because it is quick, and easy-to-use, it is hoped the T and C Test will be used for the widespread cognitive screening of aging populations.

Merkel cell carcinoma (MCC) is a rare aggressive neuroendocrine carcinoma of the skin that shows locoregional or distant metastasis. Metastasis of MCC to body cavity effusion is extremely rare; only three cases have been reported so far. Metastatic MCC in effusion cytology shows small blue round cells with fine stippled chromatin like other small blue round cell tumors such as small cell lung carcinoma or lymphoma. The diagnosis of metastatic MCC can grant patients good chances at recently advanced therapeutic options. Here, we present a case of metastatic MCC to pleural effusion with characteristic single file-like pattern.

Meningeal carcinomatosis is an important neurological complication of systemic cancer, and is increasingly being recognized as a cause of reurologic disability in life. Also there is evidenee that the incidence of this form of metastasis is increasing. We reported a case of 52-year-old female patient, who was diagnosed as early gastric cancer by biopsy under gastrofiberscopy. Other Lab. findings were all normal range except high alkaline phosphatase level. And then performed Billroth II operation. On 7th post-operative day, she was encountered severe headache and insomnia. Abnormal neurologic signs and subjective symptoms were developed and progressed, Repeated lumbar punture was done and CSF was examed. There findings were abnormal, but no specific finding of certain disease. She died of severe neurologic deficit and sudden respiratory arrest. Autopsy was done, and confirmed leptomeningeal carcinomatosis.

PURPOSE: Epistemological beliefs (EBs) are fundamental assumptions about the nature of knowledge and learning. Self-regulation (SR) is the ability and willingness to effectively use and monitor cognitive strategies. Problem-based learning (PBL) emphasizes meaningful learning through solving ill-structured problems. PBL, as a constructivist learning environment, affects students' epistemological beliefs (EBs) and self-regulation learning (SRL). The purpose of this study was to investigate the change in EBs and SRL between pre- and post-PBL. METHODS: The subjects were 123 third-year medical students who attended Chonnam National University Medical School (CNUMS), Korea. Participants had to fill out a questionnaire concerning epistemological beliefs and self-regulated learning before and after PBL. RESULTS: Students' EBs about rigid learning was positively changed; however, certainty of knowledge and speed of knowledge acquisition were negatively changed after PBL. Students' SRL related to self-efficacy and self-regulation was significantly improved in PBL. There was no significant change with regard to internal value, cognitive strategy, and anxiety. CONCLUSION: EBs on certainty of knowledge and speed of knowledge acquisition were negatively changed after PBL. This result may be due to other leaning environments besides PBL i.e., the lecture-based objective learning environment of medical school. It is suggested that partial PBL cannot fully change students' EBs to higher levels. Students' SR about self-efficacy and self-regulation was significantly improved in PBL. The characteristics of PBL: small-group discussion and co-operative team activity, as well as students-centered learning environments, facilitate self-efficacy, and self-regulation.

BACKGROUND AND OBJECTIVES: Coronary artery stenting actually shows a high efficacy in the treatment of coronary heart disease, but has the major limitation of restenosis. The ethylene-vinyl acetate copolymer (EVA), a biocompatible nondegradable copolymer, has been employed as a rate-controlling membrane in several drug delivery systems. Herein, the feasibility of an EVA-coated coronary stent was evaluated as a possible route for localized drug delivery. MATERIALS AND METHODS: A total of 15 rabbits were employed in this study. An uncoated stent was implanted into the non-diseased iliac artery in six rabbits, and an EVA-coated stent into a further nine. On the 30th day following the stent implantations, stented segments of the iliac arteries were removed for histological processing and morphometric analysis. RESULTS: The mean neointimal area of the uncoated and coated groups were 1.009 and 1.011 mm2 (p=0.56), respectively. No inflammatory cells were found in coated group. There were no apparent differences between the two groups. CONCLUSION: The results from this study have demonstrated that an EVA-coated coronary stent might be an appropriate method for the controlled-release of a drug.

BACKGROUND: Herpes zoster ophthalmicus (HZO) can involve the oculomotor nerve; however, isolated trochlear nerve palsy has rarely been reported. CASE REPORT: An 83-year-old man who suffered from HZO in the right frontal area and scalp subsequently developed vertical diplopia and severe pain. Cerebrospinal fluid examination and brain MRI revealed no abnormalities. Isolated right trochlear nerve palsy was diagnosed based on the findings of neuro-ophthalmological tests. CONCLUSIONS: Isolated trochlear nerve involvement associated with HZO is very rare and may be easily overlooked. Physicians should carefully examine oculomotor involvement in HZO.
