    Integrins and focal adhesion kinase in the malignant behavior of gliomas

    Efstathia Giannopoulou , Andreas Tzakos , Andreas A Argyriou
    Glioblastoma multiforme (GBM) is the most common type of glioma and is associated with a very poor prognosis. The standard treatment includes radiotherapy concurrent with temozolomide, however recently the Food and Drug Administration approved bevacizumab for use in patients with progressive glioblastoma following prior therapy. The limited number of treatment options points to the need for novel effective therapeutic approaches. A promising approach is the use of tyrosine kinase inhibitors (TKIs) in GBM treatment. However, the results from the majority of clinical trials using TKIs are not...

    A potential role of karyopherin a2 in the impaired maturation of dendritic cells observed in glioblastoma patients

    Konstantinos Gousias , Alexander von Ruecker , Gerrit H Gielen , Pitt Niehusmann , Andreas Waha , Hartmut Vatter , Matthias Simon
    Aim: Patients with glioblastomas demonstrate well-documented immunological impairments including decreased numbers of mature dendritic cells (DCs). Recent data identified karyopherin a2 (KPNA2), a nucleocytoplasmic shuttling receptor, as diagnostic and prognostic biomarker for gliomas. The aim of this ongoing study is to correlate parameters of immunity and nucleocytoplasmic transport in glioblastoma patients. Methods: We preoperatively collected serum from 17 patients with glioblastomas and determined DC subsets (HLA DR+ Lin-, CD34-, CD45+, CD123+, CD11+ were analyzed) using a 6-color flow...

    Aim: Several epidemiological studies have shown an inverse correlation between allergy and brain cancer. The purpose of this study was to compare the serum IgE levels between patients with gliomas and nonglial tumors and their possible prognostic role. Methods: A total of 84 patients with intracranial tumors were included in this study. At clinical presentation, estimation of serum IgE levels was assessed by nephelometry. Detailed information regarding the history of allergies was collected by interview. Results: Of the 84 cases, 42 were gliomas, 23 were meningiomas, 16 were metastases and...

    The influence of postoperative infection in survival of patients with high-grade gliomas

    George A Alexiou , Amalia Kallinteri , Euaggelos Michos , Panagiota Zagorianakou , Efthalia Priavali , Dimitrios Pachatouridis , Stamatina Levidiotou , Spyridon Voulgaris
    High-grade gliomas are the most common type of brain tumors. Of these, glioblastoma account for 60-70% and despite treatment carries a dismal prognosis. Postoperative surgical site infection has been associated with prolonged survival. Herewith, we present a case of glioblastoma and a case of anaplastic oligoastrocytoma that developed postoperative infection of the surgical site and had prolonged survival. A thorough literature review is also presented.

    Cardiac autonomic function in patients with myasthenia gravis: analysis of the heart-rate variability in the time-domain

    Sherifa Ahmed Hamed , Khaled Osama Mohamad , Mohamad Adam
    Aim: Myasthenia gravis (MG) is a neuromuscular transmission disorder caused by acetylcholine receptor autoantibodies. Cardiac autonomic dysfunctions were rarely reported in patients with MG. Functional cardiac abnormalities were variable and reported in patients at severe stages of the disease and with thymoma. We investigated cardiac functions in patients with MG using Ambulatory 24-h electrocardiographic Holter-Monitoring. Methods: This study included 20 patients with MG with a mean age of 28.45 ± 8.89 years and duration of illness of 3.52 ± 1.15 years. The standard Holter reports include...

    Central somatosensory conduction slowing in adults with isolated elevated plasma level of homocysteine

    Jin Jun Luo , Favio Bumanlag , Ramin Ansari , Ya-Mei Tang , Nae J Dun
    Aim: Elevated plasma level of homocysteine (eHcy) is a recognized risk factor for dementia. However, whether the central conduction is affected in patients with an isolated eHcy is unknown. In this study, we addressed whether central conduction is altered in adults with eHcy. Methods: Evoked potential studies including somatosensory (SSEP), visual (VEP) and brainstem auditory evoked potentials (BAEP), were performed to evaluate central conduction in patients with isolated eHcy. Results: Nine SSEP, 7 VEP, and 6 BAEP were studied in 9 patients with eHcy (age: 63.3 ± 7.5 years old, mean ±...

    Influence of chlorpyrifos oxon on the development and progression of Alzheimer's disease in amyloid precursor protein transgenic mice

    Jin Yu , Hong Zhu , Aruna Bhat , Hanaa El-Sayed , Tatyana Gudz , Sebastiano Gattoni-Celli , Mark S Kindy
    Aim: Alzheimer's disease (AD) is a devastating neurological disorder and the most common form of dementia. Until date, the cause of AD eludes us, but a number of hypotheses have been put forward to try and understand the mechanisms involved. A series of studies have indicated that environmental factors, such as pesticides, heavy metals, and others can contribute to the development and progression of AD. Based on these data, we determined the impact of pesticides (chlorpyrifos oxon [CPO]) on AD-like pathogenesis in amyloid precursor protein (APP) transgenic mice. Methods: APP mice were...

    Cardiac arrhythmia with premature ventricular contractures induced by interferon beta in a patient with multiple sclerosis

    Igor Sobol , Marina Sobol , Konstantin E Balashov
    Multiple sclerosis (MS) is an immune-mediated inflammatory and neurodegenerative disease of the central nervous system. Interferon (IFN) beta is an active ingredient of five out of twelve disease modifying treatments approved for MS. We report a case of IFN-beta-induced cardiac arrhythmia with premature ventricular contractures in a patient recently diagnosed with MS.

    Multiple autoimmune antibody limbic encephalitis: a case in a pregnant woman

    Meha Goyal , Kasey L Gildersleeve , Stuart L Tomko , Joseph S Kass
    Autoimmune limbic encephalitis is most commonly associated with antibodies against the N-methyl-D-aspartate receptor (NMDAR), among other neuronal cell surface receptors. Here, a case of a pregnant female with limbic encephalitis in the presence of multiple additional autoimmune antibodies is described. The patient was a 36-year-old female who presented with 4 days of confusion, hallucinations, hypersexuality, disinhibition, and pressured speech. The patient's work-up detected the presence of anti-NMDAR antibodies, anti-glutamic acid decarboxylase antibodies, and a yet uncharacterized...
