BackgroundThe use of intravenous recombinant tissue plasminogen activator (IV r-tPA) in early acute ischemic stroke (AIS) management faces a lot of difficulties in developing countries due to lessened guideline development with consecutive pre- and intra-hospital delay.ObjectivesThe objective was to identify the barriers facing proper utilization of IV r-tPA for AIS in Tanta University Hospitals.MethodsThe study was conducted on 4124 AIS patients eligible to use IV r-tPA divided to group-I consisting of 442 patients who arrived the hospital within <3.5 h from the stroke onset and group-II consisting of 3682 patients who arrived >3.5 h from the stroke onset. The former group was further subdivided to 238 patients who received IV r-tPA (group-Ia) and 204 patients who did not receive IV r-tPA (group-Ib) due to different obstacles.ResultsThe main causes of pre-hospital onset to arrival delay were stroke unawareness, long travel time, incorrect beliefs, non-available neurologists, stroke onset during sleep and multiple causes (18.2%, 20.5%, 12.7%, 9.1%, 16% and 23.5% of cases, respectively). Causes of non-administration of IV r-tPA in eligible patients includes prolonged door-to-needle time, financial restraints, minor strokes, unavailable beds and fear of complications (41.2%, 26%, 12.7%, 11.3% and 8.8%, respectively).ConclusionIncreasing the chance of utilizing IV r-tPA for AIS patients' needs regular updating of the stroke chain of survival system to get the highest benefits from the available resources.

Background: Idiopathic intracranial hypertension (IIH) is a disorder of unidentified etiology characterized by raised intracranial pressure (ICP) without clinical, laboratory, or radiological evidence of intracranial pathology. The aim of this work was to determine the visual outcome in newly diagnosed IIH patients. Methods: The study included 68 IIH patients; 59 responded to medical treatment and nine needed lumboperitoneal shunting (LPS). Patients were submitted to papilledema grading using Frisén Scale, water CSF manometry, brain MRI/ MRV, mean deviation of visual field examination (MD-VFE), optic nerve sheath diameter (ONSD), average optic disc optical coherence tomography-retinal nerve fiber layer (OCT-RNFL) thickness, and pattern-reversal visual evoked potential (VEP). Results: Patients needed LPS showed statistically significant increase in baseline papilledema grade, MD-VFE, ONSD, average OCT-RNFL thickness, and P100 VEP latency. On the other hand, both studied groups showed statistically nonsignificant differences regarding the patients' ages and opening CSF pressure. Conclusion: Newly diagnosed IIH patients' evaluation must be based on multimodality neuro-ophthalmological assessment where papilledema grade, MD-VFE, and OCT-RNFL are valuable biomarkers of PVD while P100 VEP latency delay is a predictor of poor visual outcome and ONSD is an early indicator of elevated ICP regression after LPS surgery.

Background Stroke is the most common acquired neurological disease in the adult population worldwide with an incidence of 16 million new cases every year responsible for about 6.1 million deaths and 130.6 million disability-adjusted life-years (DALYs). The objectives of this work were to study the level of stroke awareness and the proper response for suspected stroke patients in urban and rural areas of Tanta City, Egypt. The study was conducted on 1869 Egyptian Citizens; 908 and 961 reside in urban and rural areas, respectively, who were submitted to a face-to-face interview using the stroke awareness questionnaire (Arabic version). Results Rural participants showed a significant reduction in acute cerebrovascular stroke (CVS) awareness and knowledge including the most affected organ by CVS, what are the risk factors, what are the early stroke symptoms, is there specific treatment for acute ischemic stroke, and what is the proper reaction when confronted with a case of acute CVS? Conclusion Urban populations have better recognition of stroke risk factors, early stroke symptoms, and the proper response when confronted with a case of acute CVS when compared with rural people possibly due to better socioeconomic status and higher educational levels.

Background Essential tremor (ET) is now considered as a slowly progressive neurodegenerative disorder with a variety of motor and non-motor manifestations. The objectives of this work were to study the existence of cognitive, mood, olfactory, and balance dysfunctions in ET patients and their relation to tremor severity as well as patients’ activity of daily livings. Methods This study was performed on 36 ET patients and 24 healthy controls subjects (HCS) submitted to The Essential Tremor Rating Assessment Scale (TETRAS), advanced activity of daily living scale (AADLs), Montreal cognitive assessment scale (MoCA), Montgomery–Åsberg Depression Rating Scale (MADRS), auditory mismatch negativity (MMN), Sniffin’ Sticks test (SST), computerized dynamic posturography (CDP), and brain MRI diffusion tensor tractography (DTT). Results ET patients showed significant decrease in AADLs, MoCA, SST (threshold, identification, and discrimination subscales) as well as visual and vestibular ratios of CDP compared to HCS. Auditory MMN showed significant reduction in the amplitude and prolongation of latencies while corticospinal tracts, thalamo-cortical connectivity, and middle cerebellar peduncles DTT revealed reduced fractional anisotropy in ET patients with normal tracts densities. Conclusion ET patients exhibit a wide variety of non-motor manifestations including cognitive impairment, depressive symptoms, hyposmia, and increased risk of falls with consecutive reduced activity of daily living beyond the deleterious effects of the kinetic tremor.
