INTRODUCTION: Multiple sclerosis is most often diagnosed among young adults but less frequently it may present during childhood or adolescence. In Portugal, there has been only one previous single-center, pediatric multiple sclerosis study. The main objective was the evaluation of the demographic, clinical, laboratorial and neuroradiological characteristics of patients with pediatric-onset multiple sclerosis in Portugal. The secondary objectives were to compare the characteristics of childhood-onset multiple sclerosis and adolescent-onset multiple sclerosis and to characterize the treatments prescribed...

In Sub Kim, Won Min Jo
Although anticoagulation therapy is the primary treatment for deep vein thrombosis (DVT), it has not been associated with the rapid recanalization of the venous occlusion. Moreover, it is associated with long-term disability due to post-thrombotic syndrome (PTS). In contrast, pharmacomechanical endovascular intervention (PMI) results in more rapid clinical improvement in DVT patients, but there are few reports on its long-term outcomes. This retrospective study evaluated the clinical effectiveness of PMI compared to conventional anticoagulation therapy (ACA) for acute and subacute iliofemoral DVT...

In patients with colorectal cancer (CRC), the BRAF V600E mutation has been reported to be associated with several clinicopathological features and poor survival. However, the prognostic implications of BRAF V600E mutation and the associated clinicopathological characteristics in CRCs remain controversial. Therefore, we reviewed various clinicopathological features, including BRAF status, in 349 primary CRCs and analyzed the relationship between BRAF status and various clinicopathological factors, including overall survival...

It is important to use vancomycin in a proper manner to ensure optimal drug exposure. Despite extensive use of vancomycin in children, studies on its optimal trough concentration (Ctrough) in the pediatric population remained rare. This retrospective study included children < 18 years old with culture-confirmed methicillin-resistant Staphylococcus aureus (MRSA) bacteremia who were hospitalized in our institute from January 2010 to April 2014. Clinical characteristics, initial vancomycin dose, Ctrough and clinical/microbiological outcomes were retrospectively collected from medical records...

When do descriptive regularities (what characteristics individuals have) become prescriptive norms (what characteristics individuals should have)? We examined children's (4-13 years) and adults' use of group regularities to make prescriptive judgments, employing novel groups (Hibbles and Glerks) that engaged in morally neutral behaviors (e.g., eating different kinds of berries). Participants were introduced to conforming or non-conforming individuals (e.g., a Hibble who ate berries more typical of a Glerk)...

Lichen aureus (LA) is a variant of pigmented purpuric dermatosis that is characterized clinically by rust macules, papules or plaques, mainly on the legs. In some cases, LA can be difficult to be distinguished from nummular eczema (NE) with the naked eye. Dermoscopy can be applied to skin lesions, revealing additional features that can be highly valuable for correct diagnosis. This study was conducted to investigate characteristic dermoscopic findings of LA and to identify distinctive features that can differentiate it from NE...

K Hoshikawa, S Ono
WHAT IS KNOWN AND OBJECTIVE: Multicriteria decision analysis (MCDA) has been generally considered a promising decision-making methodology for the assessment of drug benefit-risk profiles. There have been many discussions in both public and private sectors on its feasibility and applicability, but it has not been employed in official decision-makings. For the purpose of examining to what extent MCDA would reflect the first-hand, intuitive preference of evaluators in practical pharmaceutical assessments, we conducted a questionnaire survey involving the participation of employees of pharmaceutical companies...

The ability of computational protein design (CPD) to identify protein sequences possessing desired characteristics in vast sequence spaces makes it a highly valuable tool in the protein engineering toolbox. CPD calculations are typically performed using a single-state design (SSD) approach in which amino-acid sequences are optimized on a single protein structure. Although SSD has been successfully applied to the design of numerous protein functions and folds, the approach can lead to the incorrect rejection of desirable sequences because of the combined use of a fixed protein backbone template and a set of rigid rotamers...

BACKGROUND: Laparoscopic liver resection (LLR) appears to be safe and effective as open liver resection (OLR) for hepatocellular carcinoma (HCC). However, studies comparing LLR with ORL in elderly patients are limited. The purpose of this study is to compare the clinical outcomes of LLR versus OLR for HCC in elderly patients. METHODS: A retrospective analysis was made comparing laparoscopic (n = 11) and open (n = 18) liver resections in elderly patients performed at the University of Naples "Federico II" between January 2010 and December 2014...

Streptozotocin has been widely used to mimic some aspects of Alzheimer's disease (AD). However, especially in mice, several characteristics involved in the streptozotocin (STZ)-induced AD pathology are not well known. The main purpose of this study was to evaluate temporally the expression of AD-related proteins, such as amyloid-β (Aβ), choline acetyltransferase (ChAT), synapsin, axonal neurofilaments, and phosphorylated Tau in the hippocampus following intracerebroventricular (icv) administration of STZ in adult mice...

Shota Takenaka, Hiroyuki Aono
BACKGROUND: Drop foot resulting from degenerative lumbar diseases can impair activities of daily living. Therefore, predictors of recovery of this symptom have been investigated using univariate or/and multivariate analyses. However, the conclusions have been somewhat controversial. Bayesian network models, which are graphic and intuitive to the clinician, may facilitate understanding of the prognosis of drop foot resulting from degenerative lumbar diseases. QUESTIONS/PURPOSES: (1) To show a layered correlation among predictors of recovery from drop foot resulting from degenerative lumbar diseases; and (2) to develop support tools for clinical decisions to treat drop foot resulting from lumbar degenerative diseases...

This study was conducted to illustrate the contents and potential ecological risk of heavy metals in ballast tank sediment. Ballast sediment samples were collected from six ships during their stay in shipyard, and the heavy metals were determined by inductive coupled plasma emission spectrometer. Results showed that high concentrations of heavy metals were detected in all six sediment samples following the order: Zn > Cu > Pb > Cr > As > Cd > Hg. The geoaccumulation index explained the average pollution degree of heavy metals decreased as the following: Zn > Pb > Cu > As > Cr > Hg, and the environmental risk indices suggested that concentration found of Zn, Pb, and Cu might be highly toxic to aquatic organisms...
