Background Magnetic resonance spectroscopy (MRS) is usually added to conventional magnetic imaging (MRI) refine the diagnosis of different brain lesions. Stereotactic biopsy a well-established method obtain tissues for histopathologic examination. The purpose study compare diagnostic yields MRS and stereotactic in characterization Material Methods A prospective conducted on 27 consecutive patients presenting with multifocal, diffuse, as well deeply seated intra-axial All had both MRI prior...
Background A wide variety of radiologic changes occur within and adjacent to the nidus arteriovenous malformations (AVMs) after stereotactic radiosurgery (SRS). Our objective was study magnetic resonance imaging(MRI)-defined following photon AVMs specifically correlate appearance a perinidal T2 hyperintensity signal with eventual angiographic obliteration an AVM in response SRS treatment. Material Methods This retrospective conducted on 62 patients brain who received treatments between 2004...
Background Bone marrow is a readily accessible source for autologous adult bone stem cells which can be applied therapeutically without possessing the risk of immune rejection and raising ethical concerns. The purpose this study to determine feasibility, safety, effectiveness direct transplantation in patients with chronic cord injuries. Methods Thirty consecutive (5 females 25 males, aged 6 64 y) having traumatic dorsal spinal injury durations at least months were included study. Twenty...
The purpose of this study was to analyze the significance perinidal T(2) hyperintensity appearance after radiosurgery arteriovenous malformations (AVMs), as a predictor treatment response. Our initial experience with linear accelerator (LINAC) at University California, Los Angeles, between 1990 and 1997 involved 129 patients affected by cerebral AVMs. Based upon availability neuroimaging follow-up, 48 50 AVMs were selected for review. Forty (80%) underwent complete obliteration or...
Background: Although much is known about the epidemiology of head injuries, there little information in literature injuries Egypt, general, particularly Alexandria. The purpose this study was to highlight profile road traffic accidents (RTAs)–related Alexandria during Egyptian revolution 2011. Patients and Methods: A prospective survey conducted on 970 patients (756 males 214 females, aged 6 mo 80 y; mean=31.2) admitted Main University Hospital with after RTAs period between January 2011...
Background The desired goal for treatment of cerebral arteriovenous malformations (AVMs) is complete removal or obliteration the nidus without complications. contemporary management includes microsurgery, endovascular embolization, and stereotactic radiosurgery, in a single multimodal way. This study shows initial results linear accelerator (Linac)-based radiosurgery patients with intracranial AVMs treated at Alexandria Radiosurgery Center. Methods included 13 (10 male 3 female) mean age 26...
Cerebrospinal fluid (CSF) rhinorrhoea is a leakage of CSF from the subarachnoid space through frontal, sphenoidal or ethmoidal sinuses to nose. In this study we present our experience in endoscopic repair 55 cases who were operated endoscopically trans-nasally. The success rate procedure preventing leak after first was 85.5% which increased 90.9% following second patients with persistent leak. Endoscopic approach cerebrospinal remarkably well tolerated and complication rates are low,...
Background Gliomas, in general, and astrocytomas, particular, represent the most frequent primary brain tumors. A growing body of evidence suggests that gliomas may arise from cancer stem cells, which share several characteristics with normal neural cells. Brain tumor cells have been found to express a variety markers including Nestin, can be potentially used as therapeutic targets. Dysregulation intermediate filament protein tumor-suppressor gene TP53, Ki-67 labeling index are implicated...
