BACKGROUND: Osteoporosis is an important health concern among the postmenopausal women. Therefore, it is necessary to find out acceptable screening tools for osteoporotic patients. The purpose of this study was to evaluate the Risk Index by OSTA as a screening test for osteoporosis. METHODS: The study population was 322 naturally caused menopausal women in Korea. Their was of femoral neck and lumbar spine BMD measured by DEXA. Risk Index by OSTA, based on weight and age, was calculated and the sensitivity and specificity for osteoporosis and osteopenia were evaluated. To find out the proper cut-off point for osteoporosis and osteopenia among the postmenopausal women in Korea, we also compared the sensitivity and specificity of each Risk Index value. RESULTS: The mean age and ages at menopause were 59.1(+/-6.2) and 50.7 (+/-2.7) years, respectively. The prevalence of osteoporosis was 9.6% with femoral neck BMD. For oeteoporosis, using a cut-off point of -1 yielded a sensitivity of 74.3% and a specificity of 52.2% with femoral neck BMD. Using a cut-off of -2 yielded a sensitivity of 87.3% and a specificity of 70.9%. The ROC curve showed an AUROC 0.88 for Risk Index in identifying osteoporosis. CONCLUSION: The Risk Index is an acceptable, simple and useful method in the diagnosis of osteoporosis with a Risk Index of -2 in Korean postmenopausal women.

Purpose: The purpose of this study is three-fold: 1) to evaluate factors influencing hearing aid (HA) satisfaction; 2) to provide a profile of HA satisfaction in daily life; and 3) to examine the reasons why people gave up using HAs. Materials and Methods: Data for 1148 respondents were statistically analyzed and reported. Results: In the study, age (β=-0.03, p<0.01), level of education (β=1.21, p<0.01), HA purchase price (β=1.50, p<0.01), bilateral amplification (β=1.23, p<0.01), wearing time (β=0.28, p<0.01), and HA fitting and fine tuning on a regular basis (β=1.71, p<0.01) significantly influenced HA satisfaction. In addition, the authors observed that the most satisfactory factors were clarity of sound (53.5%), people’s trust in their HA (61.7%), and listening from a quiet environment (72.8%) in the domains of sound quality, HA features, and listening environments, respectively. Finally, with multiple choices being possible, 65% of the 40 respondents who no longer used HAs answered that their HAs ended up in a drawer since the background noise was annoying and distracting. Conclusion This study is significant in that it is a large-scale multi-center research to comprehensively examine the factors influencing HA satisfaction in South Korea. This data will provide helpful information that could lead to the successful rehabilitation of hearing loss with HAs.

PURPOSE: The purpose of this study is to evaluate the findings of magnetic resonance imaging(MRI) of posterior fossa hemangioblastoma and usefulness of contrast enhancement with Gd-DTPA. MATERIALS AND METHODS: Seven patients with posterior fossa hemangioblastoma were studied with both pre- and post-enhanced MRI. The MR images were reviewed regarding the location, size, signal intensities of cysts and mural nodules, and their contrast enhancement pattern. RESULTS: Five tumors were located in cerebellar hemisphere, one in vermis, and one in posterior part of medulla. One patient with von HippeI-Lindau disease had a medullary hemangioblastoma with multiple pancreatic cysts. In 6 cases, the major portion of the tumor was cysts and had small mulkal nodules. The solid portion was relatiely lange in one case, cemprising half of the tumor Cysts were oval shaped and their sizes were 3--6.7cm in diameter. In five cases(71%), septations were noted within the cysts. Cysts were isointense or slightly hyperintense on Tl-weighted image and hyperintense on T2-weighted image compared with cerebrospinal fluid. Mural nodules were oval or rounded appearance in five cases and flattened appearance in two, and their size was 0.5--2.5cm in diameter. Mural nodules were isointense to gray matter. They were detected in five cases on Tl-weighted images and one case on T2-weighted images. In two cases, vascular signal void area was noted in mural nodules. On contrast-enhanced Tl-weighted images, all mural nodules were intensely enhanced. CONCLUSION: MRI proved to be a good diagnostic method to detect and characterize posterior fossa hemangioblastoma. The most common finding is Cystic posterior fossa lesion with enhancing mural nodule. Contrast enhancement is essential for specific diagnosis.

Leber's hereditary optic neuropathy is caused by a single nucleotide change in the mitochondrial deoxynucleic acid(mtDNA) and accounts for 30% of bilateral optic atrophy of unknown etiology. The authors found 11778 mtDNA mutation in 12 patients and evaluated the clinical manifegtations. We confirmed various phenotypes exist in Leber's hereditary optic neuropathy in Korea.

PURPOSE: There are relatively few results from studies on nodular Hashimoto's thyroiditis. In addition, some Hashimoto's thyroiditis patients present with irregular symptoms, making the distinction from malignant thyroid nodule difficult. Therefore, we performed analyses on ultrasonographic findings of nodular Hashimoto's thyroiditis. METHODS: A retrospective follow-up study was performed on 76 patients (88 nodules) diagnosed with Hashimoto's thyroiditis after undergoing fine needle aspiration biopsy from January 2009 to December 2010. A frequency analysis was performed to investigate the most common ultrasonographic findings of nodular Hashimoto's thyroiditis. In addition, patients were divided into two groups based on the presence or absence of extensive Hashimoto's thyroiditis on the parenchyma, and ultrasonographic findings were compared and analyzed for nodules in each group. RESULTS: The study was performed on 76 patients and 88 nodules. The majority of nodular Hashimoto's thyroiditis were found to be solid on ultrasonography, and echogenicity was mostly hypoechoic, with prominent hypoechoic findings being more common. Most nodules did not have a rim surrounding the margins, and absence of accompanying calcification was also noted. The comparison and analysis of ultrasonographic findings of two patient groups that were divided based on the presence or absence of Hashimoto's thyroiditis across the parenchyma, revealed no significant difference. CONCLUSION: Most nodular Hashimoto's thyroiditis cases do not present with calcification or rims and frequently present as solid and hypoechoic. It can be concluded that such findings are consistent regardless of whether there is accompanying extensive changes at the thyroid parenchyma associated with Hashimoto's thyroiditis.

Pseudomyxoma peritonei may result from implantation of benign or malignant tumor in peritoneal cavity and is filled with gelatinous material (termed "Jelly Belly") in abdominal cavity. Its origin is usually an appendiceal or ovarian mucinous adenoma or cystadenocarcinoma, but other primary origin such as uterus, intestine, pancreas and stomach umor have been reported. Generally, pseudomyxoma peritonei is slowly progressive and has low grade malignant potential. This report presents a unusual long term survival after evacuation of 15,000 cc of gelatinous material from abdominal cavity which was the low grade mucinous adenocarcinoma and a review of the current literature, management and new its concept. The origin of pseudomyxoma peritonei of this case was most likely from appendiceal mvcinous adenocarcinoma.

Left ventricular thrombus is a common complication related to acute myocardial infarction. Removing this with an incision of the free wall of the left ventricle may cause fatal cardiac dysfunction or arrhythmias. Furthermore, performing incision and suture on the fragile myocardium of an acute myocardial infarction patient may cause serious bleeding complications. If there is a patient with left ventricular thrombus who needs thoracotomy for another reason, the case is attempted with the thought that if effective intraventricular visualization and manipulation can be done, fatalities caused by incision and suture may be reduced. For patients undergoing cardiopulmonary bypass, if intracardiac manipulation is required, an endoscope can be used, and given the potential complications after the incision and suturing of the infarcted tissue, the benefits are deemed sufficient.

A 66-year-old male patient arrived at the emergency room with a crush injury to his chest. Multiple rib fractures, hemothorax on both sides, left scapular fracture, liver laceration, and retroperitoneal hematoma were found upon the radiologic examination. After closed thoracostomy, the patient had been initially admitted to the intensive care unit, but he was transferred to the general ward on the next day. On the 4th post-trauma day, the patient complained of severe pain and there was bloody drainage through the chest tube. This case is an exploration with the consideration of the possibility of major bleeding and the subsequent repair of the descending thoracic aorta. This case is regarded as a case in which the aorta wall was damaged as the sharp margin of the fractured ribs caused continuous irritation.
