One of the most important benign tumors in neurofibromatosis type 1 (NF1) is plexiform neurofibroma, and there is a risk of developing malignant peripheral nerve sheath tumor (MPNST) throughout life approximately 10%. However lesion characterization by anatomical imaging methods are not possible. Because of that most of cases goes to biopsy. Using of fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) for lesion characterization can be helpful in NF1 patients. We aimed to present an example of the efficacy of FDG-PET/CT in distinguishing benign neurofibroma from MPNST...

BACKGROUND: Currently, patients receiving vascularized composite allotransplantation (VCA) grafts must take long-term systemic immunosuppressive therapy to prevent immunologic rejection. The morbidity and mortality associated with these medications is the single greatest barrier to more patients being able to receive these life-enhancing transplants. In contrast to solid organs, VCA, exemplified by hand or face transplants, allow visual diagnosis of clinical acute rejection (AR), directed biopsy and targeted graft therapies...

BACKGROUND: From 1996 to 2000 Diefenbeck et al. carried out 6 knee vascularized composite allotransplants(VCA). The VCAs were composed of bone, soft tissue, and the femoral vascular pedicle (25-40 cm total length). All rejected between 14 to 56 months. The failures were attributed to chronic rejection (CR). In 2008 the Louisville team lost their fourth patient's hand transplant at 8 months. During the rejection workup the senior surgeon's intra-operative findings noted a thickened arterial pedicle attributed to intimal hyperplasia (IH) with significant fibrotic perivascular tissue and a near 'no flow phenomenon'...

Multiple Sclerosis (MS) is a chronic, demyelinating, inflammatory disease of the central nervous system (CNS) with a strong autoimmune component. Several genetic and environmental factors have been suggested to contribute in MS. The Epstein-Barr virus (EBV) is one pathogenic candidate proposed to be involved in the onset of MS and/or induction of subsequent exacerbations. The possible involvement of EBV in MS is highlighted by a number of national epidemiological studies showing a higher percentage of EBV seropositivity...

INTRODUCTION: Rheumatic mitral stenosis (MS) is an important health issue in developing countries. Assessment of the correct mitral valve area (MVA) is essential for the timing of intervention. Most of the parameters for the assessment of rheumatic MS are derived from Two-dimensional (2D) echocardiography. Three-dimensional (3D) echocardiography is commonly used in our daily practice at the present time. The aim of this study was to assess the value of 3D echocardiography mitral valve vena contracta area (VCA) in predicting the severity of Rheumatic MS by comparing 3D planimetry...

PURPOSE OF REVIEW: Vascularized composite allotransplantation (VCA) is a promising approach to restore the quality of life of carefully selected patients that suffered extensive injury. Although acute rejection occurs very frequently, still little is known about the specific characteristics of the VCA immune response. This review aims to highlight the current development in the field of VCA concerning the immunobiology and management of upper extremity and face transplant recipients. RECENT FINDINGS: T-cell mediated rejection is the predominant mechanism of allograft injury in VCA...

BACKGROUND: HIV infection is associated with increased susceptibility to common pathogens which may trigger chronic antigenic stimulation and hyperactivation of B-cells, events known to precede the development of AIDS-associated non-Hodgkin lymphoma (AIDS-NHL). METHODS: To explore whether cumulative exposure to infectious agents contributes to AIDS-NHL risk, we tested sera from 199 AIDS-NHL patients (pre-NHL, average lead-time 3.9 years) and 199 matched HIV-infected controls from the Multicenter AIDS Cohort Study (MACS), for anti-IgG responses to 18 pathogens using multiplex serology...

BACKGROUND: Normal morphometry of the vermis and its relation to the posterior fossa (PF) rule out most major anomalies of the cerebellum. However, accurate categorization of the position and size of the fetal vermis remains a challenge. OBJECTIVE: Our aim was to test a new method to assess the position and size of fetal vermis on 3-dimensional ultrasound (3D-US). METHODS: We measured the vermian-crest angle (VCA) in normal fetuses using multiplanar 3D-US...

1. This study aimed to evaluate the pharmacokinetic interaction of shuanghuanglian (SHL) and azithromycin in rats, and to provide experimental support for rational drug use in clinics. 2. HPLC-UV and HPLC-MS/MS approaches were respectively developed to detect the forsythiaside (active component of SHL) and azithromycin concentrations. Both non-compartmental and compartmental analyses were employed to calculate pharmacokinetic parameters. A nonlinear mixed-effects modelling method was applied to fit the drug concentration-time data...

Sohei Yamamoto, Yu Sakai
Herein, we describe an extremely rare case of gastritis due to concurrent infection with Epstein-Barr virus (EBV) and cytomegalovirus (CMV) occurring in an immunocompetent adult. The patient was a 35-year-old man who presented with slight fever, nausea, anorexia, weight loss for 3 weeks, mild transaminitis, and leukocytosis with atypical lymphocytes in peripheral blood. The clinical presentation and elevated IgM titers to both EBV-VCA and CMV strongly suggested infectious mononucleosis syndrome caused by co-infection with EBV and CMV...

Idiopathic hypersomnia (IH) is a rare central hypersomnia of unknown physiopathology. In this study, we determine if the presence of infectious mononucleosis evaluated by serological markers of Epstein Barr virus infection plays a role in this hypersomnia. Ten patients with a suspicion of IH underwent to clinical assessment, 24 h polysomnography, and serologic testing for mononucleosis including Viral Capside Antigen (VCA) IgG, the VCA IgM, and the EBV nuclear antigen (EBNA). None of the patients reported neurological inflammatory disease and viral infection prior the onset of the disease...

Previous systematic reviews have found a higher sero-prevalence of EBV antibodies in SLE patients compared with controls. Because many studies have been published, there is a need to apply more precise systematic review methods. We examined the association between EBV and SLE patients by conducting a systematic review and meta-analysis of case-control studies that examined the prevalence of EBV antibodies and the DNA-positive rate. We searched the MEDLINE and EMBASE databases from 1966 to 2018 with no language restrictions...
