Objective: To report on stroke subtypes, associated risk factors and outcome in Kuwait. Methods: The records of 62 patients (30 male, 32 female) admitted with diagnosis of stroke to Kuwait Oil Company Hospital, Kuwait, a tertiary care hospital, during a 5-year period (1995–1999), were retrospectively reviewed. Results: Small artery infarction was the most common subtype and occurred in 37 subjects (59.7%); less common were atherosclerotic large artery strokes (19 patients, 30.6%) and strokes of cardio-embolic origin (6 patients, 9.7%). Identifiable risk factors or associated morbidities were hypertension (72.5%), diabetes mellitus (69.4%), ischaemic heart disease (14.5%), history of migraine (8.1%), lone atrial fibrillation (5.0%), and valvular heart disease (1.6%). The most important determinants of a deleterious 30-day outcome, as indicated by severe disability or death, were female gender, lack of use of anti-platelet drugs, presence of a large artery infarction stroke subtype, and cardio-embolic stroke. Conclusion: Prevalence of hypertension and diabetes is high among patients with stroke in Kuwait, with rates higher than those found in any previous reports from the Gulf region. Two unusual observations were that women had a rather high frequency of stroke, and infarction of the small artery was more common than that of the large artery. Outcome, as indicated by severe disability or death, was worse among women, elderly patients, and those with large artery atherosclerotic and cardio-embolic strokes. There is some evidence that such a deleterious outcome might be ameliorated with use of anti-platelet drugs.
IntroductionBased on many preclinical and small clinical trials, stem cells can help stroke patient with the possibility of replacing the cells and supporting the remaining cells. The aim of this study was to evaluate the safety and feasibility of bone marrow mononuclear (BMMN) stem cell transplantation in subacute ischemic stroke patients.Materials and methodsThirty-nine (n = 39) patients with subacute ischemic cerebral infarct due to large artery occlusion in the middle cerebral artery (MCA) territory were recruited. They were distributed into two groups: first group (n = 21) served as an experimental group, which received intra-arterial (IA) mononuclear stem cells (bone marrow-derived mononuclear cell), while the other group (n = 18) served as a control group. All the patients were evaluated clinically by National Institutes of Health Stroke Scale, modified Rankin Scale, Barthel Index, modified and standardized Arabic version of the Comprehensive Aphasia Test, and radiological for 12 months.ResultsThe stem cell-treated group showed better improvement, but it was not significant when compared with the non-treated group. The volume of infarction changes at the end of the study was non-significant between both the groups. There was no, or minimal, adverse reactions in stem cell-treated group.ConclusionThe study results suggest that autologous BMMN stem cell IA transplantation in subacute MCA ischemic stroke patients is safe with very minimal hazards, but no significant improvement of motor, language disturbance, or infarction volume was detected in stem cell-treated group compared with the non-treated group.
Purpose: To evaluate optical coherence tomography angiography findings in patients with multiple sclerosis (MS). Methods: This prospective noninterventional study was conducted on 30 eyes of relapsing-remitting MS patients. Group (1) included 10 eyes with a history of optic neuritis (ON), group (2) included 10 eyes without any history of optic neuritis (MS-ON), and group (3) included 10 eyes of normal age/sex/refraction matched participants. Optical coherence tomography (OCT) and OCT-A (ZEISS Cirrus™ HD-OCT Model 4000 (Carl Zeiss-Meditec, Dublin, CA) of the optic disc were done for all patients. Results: The best-corrected visual acuity was diminished in MS cases, especially in patients with ON with P value <0.001. The retinal nerve fiber layer (RNFL) thickness showed a significant decrease in the average thickness and in all quadrants, notably the temporal quadrant in group 1 ( P < 0.001). Ganglion cell layer thickness was diminished in average thickness and in all quadrants in both groups of MS, but only the first group showed statistical significance with P value <0.001). In respect to optic disc perfusion, Average, superficial, and deep vascular density index (AVDI, VDI 1, VDI 2) were statistically significantly lower in groups 1, 2 with ( P -value < 0.001). Conclusion: Decreased vascular perfusion of the optic nerve in MS patients, especially in those with ON is strongly correlated with the damage of RNFL and ganglion cell layer detected by OCT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
