RESUMO
BACKGROUND: Parkinson's disease (PD) and vascular parkinsonism (VaP) have highly overlapping phenotypes, and different prognosis. This study comprehensively investigated the clinical, brain MRI and transcranial sonography differences between VaP and PD. METHODS: Forty-eight patients with PD, 27 patients with VaP, and 29 healthy controls were compared. All patients were assessed using the MDS-UPDRS, Berg Balance Scale (BBS), Ten-Meter Walking Test (10-MWT), Time Up and Go Test, and Non-Motor Symptoms Scale. Beck Depression Inventory, PD questionnaire- 39, international urine incontinence scale, cognitive assessment scales, MRI brain and transcranial colour-coded doppler. The study was registered on clinical-Trial.gov (NCT04308135) on 03/12/2020. RESULTS: VaP patients showed significantly older age of onset, shorter disease duration, lower drug doses and levodopa responsiveness, higher On and Off axial scores, On and Off BBS, higher On scores for PIGD, rigidity, bradykinesia and total motor MDS-UPDRS, lower On and Off tremor, lower-half predominance, lower asymmetrical presentation and symmetric index than PD patients. VaP patients had worse non-motor symptoms Scale (NMSS) than controls except for perceptual problems/hallucinations but better symptoms than PD patients except for urinary dysfunction. Quality of life (QoL) was impaired in VaP patients and was correlated with motor function and NMSs. The VaP group had significantly higher white matter lesions and brain atrophy, with lower hyperechogenicity of the substantia nigra and more impaired cerebral vascular resistance and vasoreactivity than the PD group. CONCLUSIONS: VaP has a characteristic motor and non-motor profile, with impaired QoL, white matter, and transcranial sonography abnormalities that differentiate it from PD. Further studies are warranted to explore the role of vascular lesions in the pathogenesis of VaP. TRIAL REGISTRATION: The registered identifier NCT04308135 on clinical-Trial.gov. Registered on 03/12/2020.

BACKGROUND: The issue of sex differences in stroke has gained concern in the past few years. However, multicenter studies are still required in this field. This study explores sex variation in a large number of patients and compares stroke characteristics among women in different age groups and across different countries. METHODS: This multicenter retrospective cross-sectional study aimed to compare sexes regarding risk factors, stroke severity, quality of services, and stroke outcome. Moreover, conventional risk factors in women according to age groups and among different countries were studied. RESULTS: Eighteen thousand six hundred fifty-nine patients from 9 countries spanning 4 continents were studied. The number of women was significantly lower than men, with older age, more prevalence of AF, hypertension, and dyslipidemia. Ischemic stroke was more severe in women, with worse outcomes among women (p: < 0.0001), although the time to treatment was shorter. Bridging that was more frequent in women (p:0.002). Analyzing only women: ischemic stroke was more frequent among the older, while hemorrhage and TIA prevailed in the younger and stroke of undetermined etiology. Comparison between countries showed differences in age, risk factors, type of stroke, and management. CONCLUSION: We observed sex differences in risk factors, stroke severity, and outcome in our population. However, access to revascularization was in favor of women.

BACKGROUND: Several studies have addressed gender differences in stroke. Yet, results are diverse, and research is still required in different populations. So, this study investigates variation in stroke according to gender in a developing country. METHODS: This is a registry-based, retrospective observational cross-sectional study comparing men and women as regards age, risk factors, stroke severity, quality of services, and stroke outcome. RESULTS: Data analyzed comprised 4620 patients. It was found that men outnumbered women, while women had an older age, more prevalence of hypertension and atrial fibrillation, with severer strokes and worse outcomes. However, there was no gender difference in promptness nor frequency of administration of revascularization therapies. CONCLUSION: Despite the gender difference in risk factors and stroke severity, we could not detect any significant disparity in acute stroke services provided to either gender. Among age categories in women, we identified differences in acute ischemic stroke subtypes, and acute management in favor of older age.

BACKGROUND: Ticagrelor is one of the most recent antiplatelet drugs to be approved to treat ischemic heart disease. Its efficacy may exceed aspirin in improving clinical outcomes in patients with acute ischemic stroke who are ineligible for rt-PA. OBJECTIVES: We evaluated the safety regarding hemorrhagic complications (as a primary endpoint) and the efficacy (as a secondary endpoint) of a 180-mg loading dose of ticagrelor given within 9 h from the onset of the first-ever non-cardioembolic ischemic stroke. METHODS: We conducted our study on patients aged 18-75 years who presented with their first clinically manifested non-cardioembolic ischemic stroke and were recruited from the emergency department OF Kafr El-Sheik University Hospitals, Egypt. Eligible patients randomly received ticagrelor or aspirin loading and maintenance doses. Screening, randomization, and initiation of treatment all occurred within the first 9 h of stroke onset. RESULTS: Eighty-five patients received ticagrelor, and 84 received aspirin. Patients who received ticagrelor had a better clinical outcome in terms of NIHSS improvement at 2 days and 1 week of discharge and a favorable mRS score after 1 week of discharge and at 90-day follow-up. There was no significant difference between the two groups regarding hemorrhagic adverse effects. CONCLUSION: This pilot study found that ticagrelor had a better clinical outcome than aspirin based on NIHSS and mRS in acute ischemic stroke patients who received it within 9 h from symptom onset and had a shorter hospital stay duration. Ticagrelor was non-inferior to aspirin regarding hemorrhagic complications. TRIAL REGISTRATION: We registered our trial on ClinicalTrials.gov, named after "ticagrelor versus aspirin in ischemic stroke," and with a clinical trial number (NCT03884530)-March 21, 2019.

COVID-19 is a pandemic disease which predominantly affects the respiratory system with high critical care mortality and morbidity; however, it also causes multi-organ dysfunction in a subset of patients. Although causality between COVID-19 and mucormycosis remains unclear, many factors including glucocorticoids, worsening of blood glucose control, and viral-induced lymphopenia have been attributed to cause mucormycosis in patients with COVID-19. In COVID-19 patients, especially those who need oxygen support, inflammatory and cytokine storm or usage of steroids make the immune system weak. This may pave the way for opportunistic infections including mucormycosis. We report fourteen cases of COVID-19 infection, who developed rhino-orbito-cerebral mucormycosis, during treatment. Early recognition of this life-threatening infection is the key to allow for optimal treatment and improved outcomes.

BACKGROUND: It has been reported that acute stroke services were compromised during COVID-19 due to various pandemic-related issues. We aimed to investigate these changes by recruiting centers from different countries. METHODS: Eight countries participated in this cross-sectional, observational, retrospective study by providing data from their stroke data base. We compared 1 year before to 1 year during COVID-19 as regards onset to door (OTD), door to needle (DTN), door to groin (DTG), duration of hospital stay, National Institute of Health Stroke Scale (NIHSS) at baseline, 24 h, and at discharge as well as modified Rankin score (mRS) on discharge and at 3 months follow-up. RESULTS: During the pandemic year, there was a reduction in the number of patients, median age was significantly lower, admission NIHSS was higher, hemorrhagic stroke increased, and OTD and DTG showed no difference, while DTN time was longer, rtPA administration was decreased, thrombectomy was more frequent, and hospital stay was shorter. mRS was less favorable on discharge and at 3 months. CONCLUSION: COVID-19 showed variable effects on stroke services. Some were negatively impacted as the number of patients presenting to hospitals, DTN time, and stroke outcome, while others were marginally affected as the type of management.

INTRODUCTION: Ticagrelor is one of the most recent antiplatelet drugs used to treat ischemic heart disease. Its efficacy may equal or exceed aspirin in improving clinical outcomes in patients with acute ischemic stroke who are ineligible for rt-PA. AIM OF THE WORK: We aimed at evaluating the safety (as a primary endpoint) and efficacy (as a secondary endpoint) of a 180 mg loading dose of ticagrelor given within 9 h from the onset of first-ever ischemic stroke. METHODS: We conducted an open-label, randomized prospective controlled clinical trial between May 2019 and September 2020 on patients who presented with their first-ever ischemic stroke and were recruited from the emergency department, of Kafr el-sheik University Hospitals, Egypt. Eligible patients randomly received aspirin or ticagrelor loading and maintenance doses. Treatment began within 9 h of stroke onset. RESULTS: Aspirin was given to 84 patients; ticagrelor was given to 85. There was no significant difference between the 2 groups regarding the hemorrhagic and nonhemorrhagic complications. Patients who received ticagrelor had a better outcome regarding NIHSS improvement at 2 days and 1 week or discharge and a favorable mRS score after 1 week or discharge and at 90-day follow-up. CONCLUSION: Ticagrelor was noninferior to aspirin regarding safety profile. Compared with aspirin, ticagrelor had a better clinical outcome based on NIHSS and mRS in first-ever acute ischemic stroke patients who received it within 9 h from symptom onset, leading to a shorter hospital stay.

BACKGROUND: Spasticity is a common complication of many neurological diseases and despite contributing much disability; the available therapeutic options are limited. Peripheral magnetic stimulation is one promising option. In this study, we investigated whether peripheral intermittent theta burst stimulation (piTBS) will reduce spasticity when applied directly on spastic muscles. METHODS: In this sham-controlled study, eight successive sessions of piTBS were applied directly to spastic muscles with supra threshold intensity. Assessment was done by modified Ashworth scale (mAS) and estimated Botulinum toxin dose (eBTD) at baseline and after the 8th session in both active and sham groups. RESULTS: A total of 120 spastic muscles of 36 patients were included in the analysis. Significant reduction of mAS and eBTD was found in the active compared to sham group (p < 0.001). The difference in mAS was also significant when tested in upper limb and lower limb subgroups. The degree of reduction in mAS was positively correlated with the baseline scores in the active group. CONCLUSION: piTBS could be a promising method to reduce spasticity and eBTD. It consumes less time than standard high frequency protocols without compromising treatment efficacy. TRIAL REGISTRATION: Clinical trial registry number: PACTR202009622405087. Retrospectively Registered 14th September, 2020.

BACKGROUND: Stroke is a leading cause of disability worldwide with a great impact on quality of life. Ain Shams University Hospital is a tertiary center for neurology and a pioneer in offering comprehensive stroke service in the region. METHODS: A cross sectional study in which an 8 domains questionnaire was applied to all cerebrovascular stroke patients who were admitted to the stroke unit of the neurology department of Ain Shams University Hospital in the period from January 2016 till May 2017, with the aim to define pitfalls in post discharge. RESULTS: From our study show that 20% of all patients discharged from acute stroke unit did not have further follow up with any stroke doctor. Moreover, 60% of patients were not seen by a physiotherapist after discharge, including almost half of patients with moderate or severe disability on discharge who are expected to have ongoing care needs. Patients who developed stroke complications were more likely to seek follow up. As expected, continuous follow up was associated with increased adherence to secondary preventive medications. CONCLUSIONS: Patient needs should be assessed before patient discharge and patient and care givers should have clear written information on required follow up with stroke doctors, and arrangements made for receiving adequate rehabilitation post discharge.

BACKGROUND: Egypt is a densely populated country with living habits and health care services that differ from urban to rural regions. We aimed to study how characteristics of stroke vary among these regions. METHODS: This is a cross-sectional observational study of ischemic stroke, thus hemorrhagic and venous strokes were excluded. A total of 1475 ischemic stroke patients were recruited for analysis from a tertiary hospital in Cairo representing urban area and from a secondary care hospital in Suhag representing rural region. RESULTS: Analysis was done for 1143 ischemic stroke patients from urban and 332 from rural area. Onset to door was shorter in urban. Urban patients showed an older age and higher prevalence of hypertension and diabetes (65.9%, 48.6% respectively), while rural patients were characterized by female preponderance (51.5%), more dyslipidemia, smoking 44.6%, stroke in young 20.5%, atrial fibrillation 23.8% % and recurrent stroke 44.3%. Rural cases showed a severer deficit at onset and poorer outcome. CONCLUSION: Vascular risk factors, stroke type, and presentation tend to differ in Egypt according to the geographic distribution whether urban or rural. Studying patterns of such difference may aid in planning specific targeted preventive and therapeutic strategies for stroke in urban and rural Egypt.

Objective: Pain is one of the most common non-motor symptoms in Parkinson's disease (PD), with variable characteristics among populations. This multicenter Egyptian study aimed to translate and validate the King's Parkinson's Disease Pain Scale (KPPS) and questionnaire (KPPQ) into Arabic versions and to investigate the pain characteristics in Egyptian people with PD (PWP). Methods: 192 PWP and 100 sex and age-matched controls were evaluated by KPPS-Arabic and KPPQ-Arabic. Both tools were assessed for test-retest reliability, floor or ceiling effects, construct validity and convert validity. PWP were assessed also by MDS-UPDRS, Hoehn and Yahr, NMSS, PD Questionnaire-39, and the Non-Motor Fluctuation Assessment (NoMoFA). Results: KPPS-Arabic and KPPQ-Arabic showed inter and intra-rater consistency and high validity, with an acceptable ceiling effect. 188 PWP (97.9%) reported at least 1 type of pain, (p<0.001). The severity and prevalence of KPPS-Arabic domains were significantly higher in all pain domains among PWP compared to controls (p < 0.001). Fluctuation-related and musculoskeletal pains were the most common (81.3% and 80.7%, respectively). In the PD group, the total and domains of KPPS-Arabic were significantly correlated to the MDS-UPDRS total, parts I, II, III, PIGD, axial, and H &Y scores, but not age or age of onset. Predictors of KPPS-Arabic included the total MDS-UPDRS, part III-Off, disease duration, total NMSS, and NoMoFA. Conclusion: The current multicentre study provided a validated Arabic versions of KPPS and KPPQ, with high reliability and validity, and demonstrated a high prevalence and severity of pain within Egyptian PWP and characterized its determinants.
RESUMO
Background: National institutes of health stroke scale (NIHSS) is used, since its appearance in analysis of stroke in any national or international single center or multicenter study. It is also the golden standard assessment scale for stroke patients whether by emergency medical services on the way to hospital or by emergency room staff and by neurologists whether juniors or senior consultants. Yet, it is not capable of identifying all stroke cases. Along the current case report a relatively rare case of cortical deafness is presented highlighting its rarity and its vascular mechanism as well as how defective is NIHSS in recognizing it. Case presentation: 72-year-old female patient presented with sudden episodic less than 60 min duration of bilateral deafness; initial imaging showed right hemispheric encephalomalacia of old stroke. Patient was initially managed as psychogenic case especially that her NIHSS was zero. On returning again to emergency room she was administered thrombolysis and regained full hearing power. Follow-up imaging revealed a new ischemic stroke along her left auditory cortex explaining her cortical deafness. Conclusion: Cortical deafness might be missed especially that NIHSS does not detect it. NIHSS role as the only golden standard scale for diagnosing and following up stroke cases ought to be revised.
RESUMO
Introduction: Stroke is the second leading cause of mortality worldwide. Five percent of all the disability-adjusted life years (DALYs) lost around the world are attributed to stroke. This study aimed to assess the economic burden of acute ischemic stroke (AIS) in Egypt and reveal the benefits of alteplase treatment by measuring the resource use and costs associated with this treatment compared to the standard of care and extrapolate the overall budget impact of alteplase to the local Egyptian setting over a 5-year time horizon from a societal perspective. Methods: A budget impact model was developed to estimate the impact of adding alteplase to the current treatment of AIS patients within the Egyptian healthcare setting. The efficacy data for both arms of the model were sourced from a systematic review of the literature. Resource use and cost data were sourced from a retrospective study. Proportions of patients potentially eligible for treatment and the treatment time distributions were estimated from an analysis of the results of this retrospective data collection. A univariate sensitivity analysis was conducted to assess the robustness of the model results. The input parameters varied between plausible extremes based on a review of available evidence. Results: The total annual costs with alteplase treatment [i.e., drug, symptomatic intracerebral hemorrhage (ICH) management, acute hospitalization, and post-hospitalization costs] for the targeted patients from a societal perspective were estimated to be less than the total annual costs without alteplase. This resulted in savings of approximately EGP 37.2 million ($ 1.2 million), EGP 14.2 million ($ 458.06), EGP -33.0 million ($ -1.06 million), EGP -54.0 million ($ -1.74 million), and EGP -89.8 million ($ -2.89 million) for each of the 5 years, respectively. In year 1, more than 2,787 patients (+30.1%) achieved an excellent outcome and <1,204 patients (-22.3%) had a poor outcome when treated with alteplase. The savings in acute hospitalization and post-hospitalization costs offset the increase in drug and ICH management costs in the alteplase group compared to treatment without alteplase. The total cumulative cost savings for alteplase in AIS patients were estimated at EGP -228,146,871 ($ -7,359,576) over 5 years. Conclusion: The budget impact model estimates suggest that from a societal perspective, alteplase is likely to be a cost-saving option for the treatment of AIS in Egypt due to the treatment benefits, resulting in savings in acute hospitalization and annual post-hospitalization costs.
RESUMO
Background: Acute stroke management is well-established in developed countries with no gender difference. Yet, in developing countries there are reports on gender disparity in medical services including stroke services. Egypt, a developing low-middle-income country, heavily populated, in the Middle East is a good example to answer whether acute ischemic stroke service is provided equally to males and females or there is disparity in risk factors, onset to door (OTD), door to needle (DTN), and outcome. The current study was prospective observational analytical hospital-based study, on acute ischemic stroke cases admitted to Nasr city insurance hospital stroke unit between September 2020 and September 2022. Results: 350 cases were included, 257 males and 93 females. Hypertension was the commonest risk factor 66% males and 81% females P = 0.011, atrial fibrillation was predominant in females P < 0.001, smoking was predominant in males P < 0.001. Median OTD in hours was 8.0 among both genders with minimum zero and maximum 96 h in males compared to minimum 1 and maximum 120 h in females, DTN was around 30 min with no significant difference. Median NIHSS on which rtPA was administered was 12.5 (6-13) in females compared to 10 (6-12) in males. Males who did not receive rtPA had a better mRS on discharge and on 90 days P = 0.01, 0.009, respectively, while there was no significant difference on discharge and 90 days between both genders on receiving rtPA. Conclusions: No gender disparity was found in DTN, discharge outcome, and 90 days among rtPA recipients. Females tended to have higher NIHSS and relatively delayed presentation to ER with less favorable outcome at discharge and 90 days in case of not receiving rtPA. Encouraging earlier arrival and conducting awareness campaigns for risk factors management is warranted.
RESUMO
BACKGROUND: The NIHSS is used routinely but has drawbacks. One of them is its inefficiency in detecting all signs of posterior circulation strokes. Since its declaration as a possible substitute for NIHSS in posterior circulation strokes in 2016; the expanded NIHSS (e-NIHSS) has not been paid much attention. The current study assesses clinically the value of e-NIHSS over NIHSS in posterior circulation strokes as regards the percentage of cases with different/higher scores, the significance of such scoring on management decisions, the weight of baseline e-NIHSS as a prognostic tool on 90 days functional outcome and its cut off value. METHODS: The current longitudinal observational study was conducted on 79 cases after formal written consent who presented with posterior circulation strokes and confirmed by brain imaging. RESULTS: In Comparison to NIHSS; the e-NIHSS score was higher in 36 cases at baseline and in 30 cases on discharge. The e-NIHSS median was two points higher at baseline and 24 h and was one point higher on discharge P < 0.001. A baseline moderate/moderate-severe was more common with e-NIHSS (n 50, 63.3%). In terms of 90 days outcome; a less favorable outcome (>2) was evident in cases with different scoring (e-NIHSS > NIHSS) indicating more sensitivity of e-NIHSS in prognosing 90 days outcome. ROC curve showed 82% sensitivity and 81% specificity with a significant area under the curve (=0.858) on scoring ≥ 8 in e-NIHSS. CONCLUSION: e-NIHSS is diagnostically and prognostically relevant tool in posterior circulation strokes and ought to be considered in future guidelines.

Despite the enormous health burden of lacunar stroke, data from low- and middle-income countries on lacunar stroke characteristics and its comparison with that of high-income countries are scarce. Thus, we aimed to investigate and compare the variable characteristics and vascular status in patients from Egypt and Germany suffering lacunar stroke. Two cohorts of lacunar stroke patients from Ain Shams University Hospital, Egypt and Goethe University Hospital Frankfurt, Germany were retrospectively collected between January 2019 and December 2020 and analyzed for demographics, risk factors, mode of presentation, neuroimaging features, treatment protocols and outcomes. MRI showed a different distribution pattern of lacunar strokes between cohorts, detecting posterior circulation lacunar infarctions preponderantly in patients from Egypt and anterior circulation lacunar infarctions preponderantly in patients from Germany. Complementary MR/CT angiography revealed a significantly higher proportion of intracranial and combined intracranial and extracranial arterial stenosis in patients from Egypt than in patients from Germany, suggesting differences in pathological processes. Younger age, higher NIHSS on admission, and posterior circulation lacunar infarction were predictors of Egyptian origin, whereas hypertension was a predictor of German origin. Our results support the idea of clinical and neuroimaging phenotype variations in lacunar stroke, including different sources of lacunar stroke in patients of different populations and geographical regions. This implies that guidelines for management of lacunar stroke might be tailored to these differences accordingly.

OBJECTIVES: Stroke represents a health care challenge to most parts of the world including the Middle East and North Africa (MENA) region. The MENA represents 6% of the world population with an age-standardized stroke rate of 87.7 (78.2-97.6) per 100,000 population. This number is subject to increase given that the cause of morbidity has recently shifted from infectious diseases to non-communicable diseases. Thus, in the coming years, treatment of stroke will pose a major burden on MENA countries which mostly lie in the low to middle income economies. Accordingly, we need to study the state of MENA stroke services in order to recognize and further inform policy makers about any gaps that need to be bridged in this domain. METHODS AND RESULTS: Stroke specialists representing 16 countries filled an online survey that included: screening for risk factors, acute management, diagnostics, medications, post-discharge services, and stroke registries. Results showed that 11 countries screen for risk factors, 16 have neuroimaging studies, 15 provide intravenous thrombolysis (IVT), 13 mechanical thrombectomy (MT) while medications for secondary prevention are available in all countries. However, stroke units are not equally available and even absent in 4 countries, and despite the availability of IVT yet, the rate of administration is still low in 6 countries (<5%), and ranges from 5-20% in 7 countries. Stroke registries and training still need to be implemented in most countries. CONCLUSION: Although imaging, revascularization therapies and medications for secondary prevention are available in most MENA countries, yet the rate of revascularization is low, so is the number of stroke units insufficient in some countries. Additionally, registries and structured training are still defective. Further field studies are required for more accurate determination of the status of stroke services in the MENA region.

Pandemic represents challenging medical emergency as it is usually associated with high rates of mortalities and morbidities. Along the last 2 and half years the world has faced the emergence of severe acute respiratory syndrome corona virus 2 pandemic that caught medical agencies and health authorities by surprise and costed more than half billion morbidities and 6 million mortalities. Unfortunately, the way developed countries contained the novel corona virus was unsatisfactory in means of early quarantines as well as obtaining and distributing an effective vaccine. This failure in management might have been responsible for the emergence of a new potential pandemic caused by monkeypox virus. Along the current review article, a detailed comparison is presented between corona virus and monkeypox virus based on virological characteristics, role of corona virus in monkeypox spread, pathogenesis, neuropsychiatric manifestations, and treatment and management. It is obvious that both viruses have a major role in causing various neuropsychiatric manifestations. Neurological manifestations are either bound directly to the virus spread to central and peripheral nervous system or secondary to triggering an immune reaction. Psychiatric ones are mostly related to stigmatization, isolation as well as changes that takes place in neurotransmitters and their metabolites within the nervous system. Dealing properly with monkeypox virus spread through previously learned lessons from corona virus might protect the world from a new pandemic.
