The published case series have suggested that appetite suppressants had some association with the development of stroke. Phendimetrazine is an appetite suppressant with sympathomimetic activity and it has a similar chemical structure with amphetamines. We report that a 22-year-old woman who had taken phendimetrazine for one month developed sudden right homonymous hemianopsia. MRI showed acute infarction in the territory of left posterior cerebral artery (PCA). Phendimetrazine should be considered as a cause of ischemic stroke.

Eosinophilic abscess is a rare disease of stomach that consists of many eosinophils in submucosa and muscle layers of stomach. Eosinophilic abscess is usually observed in liver after parasite infestation such as hepatic fascioliasis or in intradermal lesion of pemphigus. A 67-year-old female was admitted due to epigastric pain and indigestion. Endoscopic finding suggested early gastric cancer type IIc with the depth of invasion to mucosal layer at the lesser curvature of lower body. Histologic examination of endoscopic biopsy proved to be signet ring cell type adenocarcinoma. On endoscopic ultrasonography, the tumor was imaged as a slightly elevated mass with 15 mm in diameter. The lesion was localized from the first layer to the fourth layer which correspond to the mucosa and the proper muscle layer, The lesion consisted of low echoic and isoechoic densities. The lower echoic lesion ranging from the third layer to the fourth layer was thought to be necrotic or hemorrhagic portion within the tumor. Subtotal gasterectomy was performed. We compared the endoscopic and endosonographic features with the histologic findings of the resected stomach. Histologic examination showed signet ring cell carcinoma in mucosal layer and eosinophilic abscess in submucosal and proper muscle layer. We concluded that the endosonographic depth of invasion was overestimated because of the eosinophilic abscess.

The right and left hemispheres of the brain play somewhat different roles but help each other perform higher cortical functions. A 43 year-old right-handed woman was admitted due to a intraventricular hemorrhage followed by hydro-cephalus. A brain MRI revealed an intraventricular hemorrhage in the lateral, 3rd, and 4th ventricle and the hemorrhage in the lateral ventricle was compressing the genu of the corpus callosum. When asked to draw the face of a clock, she placed the numbers in reverse order (counter clockwise) when performing the task with her right hand, whereas the same task performed by the left hand was normal. In addition, when she wrote out simultaneously with right and left hands , she wrote Korean words in their mirror image with her left hand . When she wrote Chinese characters, she performed better with her right hand. These findings revealed some aspects of interhemispheric interaction in processing the images of a clock, and the orthographic lexicon of Korean and Chinese characters.

PURPOSE: To evaluate the reliability of Singh index (SI) values, determined on image software processed digital radiographs in elderly patients with proximal femoral fractures, with respect to its value as a simple and inexpensive method to evaluate osteoporosis in acute trauma situations. MATERIALS AND METHODS: The authors retrospectively reviewed 210 patients (98 femur neck fractures, 112 intertrochanter fractures) treated between March 2005 and March 2009. Preoperative digital radiographs of each patient were assessed by four observers to determine SI values. The reliability of SI was expressed in terms of intraobserver and interobserver agreements in pairs using Fleiss's overall Kappa, Stuart's tau-c index, and Kendall's coefficiency of concordance. RESULTS: Fleiss's overall kappa values for intraobserver agreement ranged from 0.278 to 0.586 (mean, 0.452) and did not reach good reliability overall. Fleiss's overall kappa values for interobserver agreement ranged from 0.120 to 0.241 (mean, 0.180), and thus, did not reach acceptable reliability. CONCLUSION: The result suggest that the image adjustment tools provided by digital radiography cannot improve the usefulness of SI as a simple and inexpensive method of assessing the osteoporosis. Therefore, the reliability of SI good enough to be used for clinical and research work is questionable.

Recently the transcriptional up-regulation of human beta-defensin 2 (HBD-2) by lipopolysaccharide (LPS) was found to be associated with NF-kappaB binding site. Although the general mechanisms of NF-kappaB activation by LPS stimulation are well understood, less is known about the signal transduction pathway leading to LPS-induced NF-kappaB activation in human corneal epithelial (HCE) cells. The aim of this study was to investigate the intracellular signals involved in LPS-induced HBD-2 mRNA expression in HCE cells. Pretreatments of inhibitors for NF-kappaB, protein tyrosine kinase, p38 mitogen activated protein kinase (MAPK), and c-Jun N-terminal kinase (JNK) attenuated the LPS-induced NF-kappaB DNA binding activity and HBD-2 mRNA expression. Furthermore, pretreatments with inhibitors for protein kinase C (PKC), phosphatidylcholine-phospholipase C, phosphatidylinositol-phospholipase C, or phosphatidate phosphohydrolase prevented LPS-induced HBD-2 mRNA expression and HBD-2 prmoter-driven luciferase activity. However, the increased expression of HBD-2 mRNA and the increased DNA binding activity of NF-kappaB induced by LPS were not changed by the blockage of extracellular signal-regulated kinase (ERK) and of addition of antioxidants. Forskolin, a protein kinase A (PKA) agonist did not induce HBD-2 mRNA expression. These data demonstrate that LPS-induced HBD-2 mRNA expression via NF-kappaB is, at least in part, dependent on PKC, p38 MAPK, JNK, and protein tyrosine kinase status, but appears to be independent on PKA, ERK and ROS in HCE cells. Taken together, there may be more than one signaling pathways that lead to LPS-induced up-regulation of HBD-2 mRNA expression in HCE cells.

BACKGROUND: Tuberculin skin test is a method to examine M. tuberculosis infection and has been used all over the world. But various factors make it difficult to understand testing results. In 2000, the American Thoracic Society recommended that skin test results should be decided by considering risk factors of the tested. In Korea, high tuberculosis infection rate and BCG vaccination rate make it difficult to differentiate current infection, past infection, and no infection by the skin test. This study was attempted to examine a negative predictive value of the skin test to understand how the skin test acts on deciding administration of anti-tuberculosis drug. METHOD: From Mar. 1 to Jul. 31 in 2001, the test was performed for patients hospitalized in Department of Internal Medicine, Hallym University College of Medicine, Chunchon, Korea by administering Tuberculin PPD RT23 2 TU (0.1 ml)to them that has been currently used in Korea based on Mantoux method. They were decided to be infected with tuberculosis bacilli by following diagnostic standard: 1) tuberculosis bacilli was cultured in sputum by microbiological diagnostic standard or Acid-fast bacilli was proven on a microscopic examination or 2) tuberculosis bacilli was not proven in the aforesaid microbiological test by clinical diagnostic standard, while there was opinion or symptom suitable for tuberculosis by radiographic or histological standard so the doctor decided to apply the tuberculosis treatment. RESULTS: In this study, total 210 patients except 20 patients (8.7%) among 230 hospitalized patients were evaluated. Their average age was 60 16.8 years, and male-female rate was 1.28 : 1 (male: 118, female: 92). Number of patient, who was diagnosed and decided as tuberculosis, was 53(25.2%). Pulmonary tuberculosis was found in 45 patients (84.9%); 22 patients were decided to be positive in the Acid-fast bacilli smear test by microbiological examination (culture positive: 13, culture negative: 9), and 23 patients were decided to be tuberculosis patients by clinical diagnosis standard. Tuberculosis pleuritis was found in 8 patients (15.1%); 4 patients were diagnosed and decided by histological standard, and 4 patients were decided and treated by clinical standard. In differentiating patients into 'Negative' and 'Positive' by the skin test standard of the American Thoracic Society, negative predictive value 92.3%, positive predictive value 47.3%, sensitivity and specificity were 83%, 68.8%, respectively. CONCLUSION: In hospitalized respiratory patients, there was high negative predictive vlaue 92.3% by tuberculin skin test, therefore skin test would be a important factor for deciding administration of anti-tuberculosis drug on negative skin test patient.

BACKGROUND AND PURPOSE: Remnant lipoproteins (RLPs) are products of partially catabolized chylomicrons and very-low-density lipoprotein, from which some triglycerides have been removed. These particles are smaller and denser than the parent particles and are believed to be strongly atherogenic. We explored the association between RLP cholesterol (RLP-C) and ischemic stroke, including stroke subtypes. METHODS: A cohort of 142 ischemic stroke patients (90 men and 52 women; age, 65.2+/-12.8 years, mean+/-SD) was enrolled; all had acute infarcts confirmed by diffusion-weighted MRI, and had fasting lipograms. A full stroke-related evaluation was conducted on each patient. An outpatient population of 88 subjects without a history of cerebrovascular or cardiovascular disease served as a control group. Serum RLP fractions were isolated using an immunoaffinity gel containing specific antiapolipoprotein (anti-apo)B-100 and anti-apoA-I antibodies. RLP-C values were considered to be high when they were in the highest quartile of all values in the study. RESULTS: High RLP-C values were more common in stroke patients than in control patients (31.0% vs. 14.8%, p=0.01), when 5.6 mg/dL (>75th percentile) was used as the cutoff value. Multivariable analyses indicated that RLP-C was a risk factor for stroke, with an odds ratio of 2.54 (p=0.045). The RLP-C level was higher in the large artery atherosclerosis subgroup (5.7+/-3.9 mg/dL) than in any other stroke subgroup (small vessel occlusion, 4.9+/-5.9 mg/dL; cardioembolism, 1.8+/-2.3 mg/dL; stroke of undetermined etiology, 3.1+/-2.9 mg/dL). CONCLUSIONS: We have found an association between high RLP-C levels and ischemic stroke, and in particular large artery atherosclerotic stroke.
