Background: The aim of this study was to investigate the correlation between bone mineral density (BMD) and body composition measured by the Osteosys Primus® and the GE Lunar Prodigy® and to calculate the conversion rate between the 2 devices. Methods: The 40 subjects were men and women in aged 20 to 29 years old. All participants were scanned twice on both the Osteosys Primus (OsteoSys) and the GE Lunar Prodigy (GE Healthcare) DXA systems using the manufacturers’ standard scanning and positioning protocols. Results: Compared to the GE Lunar device, the mean Osteosys fat mass was overestimated to be 12.1% (1,776.9 g) in the whole body, 5.1% (163.9 g) in gynoid, and 6.7% (87.2 g) in android. Compared with the GE Lunar device, the mean BMDs of the Osteosys Primus were underestimated to be 2.3% (0.023 g/cm2) in the whole body and 3.1% (0.035 g/cm2) in L1-4. Compared with the GE Lunar device, the mean lean mass derived by the Osteosys Primus were underestimated to 2.3% (1,045.3 g) in the total body, 3.8% (179.4 g) in arms, and 7.7% (1,104.8 g) in legs, respectively. There were a strong correlation of BMD and body composition between both groups. Conclusions Linear correction equations were developed to ensure comparability of BMD and muscle mass between the Osteosys Primus and the GE Lunar Prodigy. Importantly, use of equations from previous studies would have increased the discrepancy between the Osteosys Primus and the GE Lunar Prodigy.

PURPOSE: The purpose of this study was first to identify knowledge about, attitude toward, and educational needs for dementia in certified caregivers; secondly, to understand the relationships among those variables; and thirdly, to provide base-line data for education program development. METHODS: The participants in this study were 670 certified caregivers who were working in nursing homes or care hospitals throughout the whole of the country and engaged in education programs for improvement of their professional abilities. Collected data were analyzed using t-tests, ANOVA, Duncan, and Pearson's correlation coefficients with the SPSS 18.0 for Windows Program. RESULTS: The scores for knowledge about, attitude toward, and educational needs for dementia were 14.12+/-2.83 out of 20, 42.27+/-5.54 out of 50 (item mean 4.22), and 121.51+/-22.13 out of 160 (item mean 3.79) respectively. There were statistically significant positive correlations between knowledge and attitude (r=.238, p<.001), educational needs (r=.083, p=.032), and attitude and educational needs (r=.244, p<.001). CONCLUSION: Tailored and continuous educational programs for certified caregivers that can improve knowledge about the causes and symptoms of dementia should be developed. Nurses and professors who are experts in dementia should be on the front lines of education for caregivers.

BACKGROUND: In geriatric patients, cardiovascular disease is common and a main cause of perioperative morbidity and mortality. Therefore preoperative evaluation of cardiac function is important. The purpose of this study is to evaluate preoperative echocardiography in geriatric patients for understanding aging heart changes and proper selection of patients. METHODS: In the 381 geriatric patients, authors evaluated chamber size, wall thickness, wall motion, valve abnormalities and ejection fraction. In addition, in patients who had left ventricular dysfunction (ejection fraction < OR = 55%), authors evaluated past medical histories and electrocardiographic (ECG) findings. RESULTS: Left atrial enlargement was present in 16%, left ventricular enlargement in 3%, right ventricular enlargement in 6%, ascending aorta dilatation in 13% and left ventricular hypertrophy (LVH) in 28%. Aortic regurgitation (AR) was present in 44%, mitral regurgitation (MR) in 42%, aortic valve calcification in 21% and hypokinesia of the left ventricular wall in 4%. Left ventricular dysfunction was present in 18 patients and their past medical histories showed hypertension in 39%, myocardial ischemia in 33%, congestive heart failure in 28% and diabetus mellitus in 28%. Also their ECG findings showed LVH in 45%, atrial fibrillation in 30% and ventricular premature contraction in 15%. Among the 18 patients with left ventricular dysfunction, 16 patients (89%) had dyspnea or heart disease histories such as myocardial ischemia, myocardial infarction, congestive heart failure, premature ventricular contraction and atrial fibrillation. CONCLUSIONS: 16% of the patients showed a normal echocardiograpy. Abnormal findings of the echocardiography were, in order of frequency, AR (44%), MR (42%) and LVH (28%). Dyspnea or cardiac disease histories were present in 89% of the left ventricular dysfunction patients.

The aging of the Korean population is expected to increase the prevalence of osteoporosis and related fractures. This study aimed to perform an intensive review of osteoporosis and related fractures in Korea during the last decade. Although direct comparison of the prevalence of osteoporosis reported in different studies is difficult, the prevalence of osteoporosis reported in the last decade has ranged from 6.1% in men and 24.3% in women to 13.1% in men and 35.5% in women in studies of Korean populations. According to reimbursement records from the National Health Insurance Servicesdatabase in 2012, the incidence and mortality of osteoporotic fracture including in the spine, hip, distal radius, and proximal humerus are 655.4/100,000 and 7.0%, 171.3/100,000 and 16%, 474.1/100,000 and 1.7%, and 90.9/100,000 and 7.0%, respectively. The numbers and incidence of hip and spine fracture were trending upward during the study period. However, mortality from osteoporotic fractures was steady or trended downward. Gender-specific assessment showed that although the incidence of osteoporotic fracture in men is less than in women, the mortality of men after osteoporotic fracture ranged from 1.4- to 2.2- fold that of women. Our review of epidemiologic studies regarding osteoporosis and related fractures demonstrated that Korea is a country with increasing trends of osteoporosis and related fractures. Therefore, a public health strategy for treating osteoporosis and preventing osteoporotic fracture is mandatory.

PURPOSE: Mycobacterium tuberculosis usually affects the lungs, although it may involve various segments of the eye and cause severe visual loss if not treated properly. We report the case of Mycobacterium tuberculosis keratitis treated successfully with antituberculous medication and amniotic membrane transplantation. METHODS: A 48-year-old male patient diagnosed as cervical tuberculous lymphadenitis about 20 years ago was referred from other hospital. He complained about painless corneal opacity on right eye. And other systemic evaluation other than cervical lymphadenitis was not remarkable. On biomicrosopy, peripheral multiple corneal opacity and neovascularization were observed. Fortified tobramycin eyedrops and oral antituberculous medication were used preoperatively. Under local anesthesia, the lesion was removed, and lamellar keratoplasty with lyophilized cornea and amniotic membrane transplantation was performed. Amikacin eyedrops was used postoperatively. RESULTS: From postoperative day 15, corneal opacity was decreased gradually. CONCLUSIONS: Mycobacterium tuberculosis should be considered as one of the causes of keratitis manifesting painless corneal opacity concomitant with cervical tuberculous lymphadenitis. Proper examination and management are necessary.

BACKGROUND AND OBJECTIVES: Herpes zoster(HZ) is a well known viral infection of the nervous system. HZ is associated with the neurologic complication. It may have been expected a change in the cerebrospinal fluid(CSF) of patients with HZ. The purpose of this paper is to present the correlation between CSF findings and neurologic complications in HZ. METHOD: The patients(n=75) with HZ were 31 male and 26 females, who were ranged in age from 15 to 79years(mean 53.4 years) admitted to department of Neurology of Chung Ang Gil General Hospital from June 1992 to May 1995. The patients were evaluated for the etiology, lesion distribution, and complications. CSF study was performed in 32 patients(male/female=20/12), whose age ranged from 16 to 79 years(means 51years) during 5 days to 10days after initial symptom onset. CSF findings were analyzed for their etiology, lesion distribution and complication. RESULTS: The CSF of 25 patients(78.1%) showed pleocytosis(5 to 49/mm3 in 10 patients, means, 62.1/mm3). 7 patients(12.3%) had meningitis symptoms, whose cell counts of CSF were more than 50/mm3(means 128.4/mm3) postherapeutic neuralgia was more common in elder patient than younger patients(p=0.005). Complications tended to correlate with the cell counts of CSF. There was no difference in CSF finding between cranial segmental involvements. CONCLUSION: We confirmed the pleocytosis in CSF of patients with HZ and suggest the development of complications in patients in patients with HZ tend to correlate with the cell counts of CSF.
