PURPOSE: To analysis the efficacy of MRI in assessing fracture configuration and frequency of associated soft tissue injuries in tibial plateau fractures. MATERIALS AND METHODS: In the plain films and MRI of 47 cases with tibial plateau fractures,every fracture was classified by findings on plain film and MRI respectively according to the Schatzker system and they were compared with each other. The degree of displacement and depression of the fracture fragments were measured on plain film and MRI. RESULTS: MRI was more accurate in determining the classification of the fracture and measuring the displacement and depression of fragments. Fracture classifications were changed in 12 cases. Especially in Schatzker VI cases, articular step off over 2 mm and articular fragments over 2X2 cm were revealed in detail by MRI. Evidence of internal derangement of the knee was found in 38 (80.8%) cases. CONCLUSION: Most of the cases with acute tibial plateau fracture were commonly associated with ligamentous and meniscal injuries. MRI can aid in accurate evaluation of tibial plateau fracture patterns and decision of treatment plan.

As a nanotechnology has been actively applied to the overall areas of scientific fields, it is necessary to understand the characteristic features, physical behaviors and the potential effects of exposure to nanomaterials and their toxicity. In this article we review the immunological influences induced by several nanomaterials and emphasize establishment of the animal models to estimate the impact of these nanomaterials on development of immunological diseases.

We present three neuropathologically-verified and two clinically-probable cases of Creutfeldt Jakob disease. All five had nonspecific prodromal complaints or symptoms prior to overt neurological signs and showed striking progressive neurologic deterioration, especially cognitive decline and cerebellar dysfunction. Myoclonic involuntary movements and complete decapitated states followed in one or two months. The characteristic even pathognomonic in proper clinical settings, features of electroencephalography, magnetic resonance imaging and positron emission tomography and pathologic findings are presented.

BACKGROUND: Type 2 diabetes mellitus (T2DM) has a strong genetic component, and its prevalence is notably increased in the family members of T2DM patients. However, there are few studies about the family history of T2DM. We carried out this study to assess the influences of family history on clinical characteristics in T2DM patients. METHODS: This is a cross-sectional study involving 651 T2DM patients. Patient history and physical examination were performed and fasting blood was taken. If any first degree relative was diabetic, a family history of diabetes was considered to exist. RESULTS: Among the total 621 patients, 38.4% had a family history of diabetes. Patients with a family history had a younger age, higher weight, younger age at diagnosis and higher triglyceride level than did those without a family history. Dyslipidemia medication and metabolic syndrome were more prevalent in familial diabetes. Sex, blood pressure, previous treatment for diabetes, HbA1C, C-peptide, total cholesterol, high density lipoprotein cholesterol, and low density lipoprotein cholesterol were not different between familial and non-familial diabetes. Upon multiple linear regression analysis, the family history of diabetes remained significantly associated with serum triglyceride level. CONCLUSION: In T2DM patients with a family history of diabetes, the disease tended to develop earlier. Metabolic syndrome and cardiovascular risk factors are more prevalent in familial T2DM than they were in non-familial T2DM. These results support the necessity of earlier screening for diabetes in family members of T2DM patients and more active prevention against cardiovascular disease in T2DM patients with a family history.

OBJECTIVE: The purpose of this study is to examine the difference between the numbers of patients in rheumatoid arthritis (RA) who are eligible to TNF inhibitors by the past Korean National Health Insurance reimbursement guideline and by the disease activity score with 28-joint assessment (DAS28) based criteria. METHODS: Data were obtained from a multi-center registry for biologics users in Korean RA patients, BIOlogics Pharmacoepidemiologic StudY (BIOPSY). DAS28 was calculated based on either ESR or CRP, and DAS28 of more than 5.1 or between 3.2 and 5.1 with radiographic changes was defined as a cut-off point for the initiation of TNF inhibitors. For the maintenance criteria, we used both of improving in DAS28 score (>1.2) and low disease activity (DAS 28<3.2). Differences between the numbers in each step by two criteria were described with Chi-square test and Kappa agreement. RESULTS: Of the 489 patients in BIOPSY, 299 were included in this study. Among them, 278 patients (93.0%) were eligible of TNF inhibitors when we applied the new initiation criteria with DAS28-ESR, and 244 patients (81.6%) were indicated for TNF inhibitors with DAS28-CRP. For the maintenance criteria, a low disease activity (DAS28<3.2) in 3 months after starting TNF inhibitors is too strict for achieving (33.6% with DAS28-ESR and 50.0% with DAS28-CRP). Instead, decreasing DAS28 by more than 1.2 is more reasonable as a tool for deciding early responsiveness of TNF inhibitors in RA patients (81.2% both with DAS28-ESR and DAS28-CRP). CONCLUSION: Our results show that the candidates for TNF inhibitors will be enormously changed according to a change in the reimbursement criteria. To define appropriate patients to receive TNF inhibitors, a further study with regard to the impact of changes in the reimbursement criteria on the outcomes of RA patients will be required.
