Real-world retrospective study of effectiveness and safety of FINgOlimod in relapsing remitting multiple sclerosis in the Middle East and North Africa (FINOMENA).

Objectives: Evidence on the effectiveness and safety of fingolimod in real-world clinical practice in the Middle East and North African (MENA) region is limited. This study aimed to evaluate the effectiveness and safety of fingolimod in patients with relapsing-remitting multiple sclerosis (RRMS) in real-world setting in the MENA region.

Patients And Methods: RRMS patients who had been treated with fingolimod for at least 12 months were retrospectively identified from the databases of 34 centers across the MENA region.

Catastrophic relapses following initiation of dimethyl fumarate in two patients with neuromyelitis optica spectrum disorder.

We report two cases of neuromyelitis optica spectrum disorder (NMOSD) who were misdiagnosed as multiple sclerosis (MS) and developed catastrophic relapses following initiation of dimethyl fumarate. Both patients developed a severe myelitis extending from the cervical cord to the medulla with significant cord swelling, resulting in complete quadriplegia and respiratory difficulties, in addition to severe bilateral visual loss in one patient. It is of note that both catastrophic relapses occurred 2 and 3 months following initiation of dimethyl fumarate.

Internal carotid artery stenting in patients over 80 years of age: single-center experience and review of the literature.

Background: Thirty percent to 40% of strokes in the elderly are secondary to carotid bifurcation disease. The treatment of internal carotid artery (ICA) stenosis in this patient population is a clinical dilemma. Age more than 80 years is a risk factor for carotid endarterectomy (CEA).

Advances in treatment of acute ischemic stroke.

Stroke carries a severe toll in terms of loss of life and disability for patients and their families. Until 10 years ago, physicians, and in particular neurologists, had a conservative, non-aggressive approach to this devastating disease. The advent of thrombolytic therapy not only proved that acute ischemic stroke is treatable, but also that early reperfusion can dramatically change the outcome of acute stroke patients.

Stroke carries a severe toll in terms of loss of life and disability for patients and their families. Until 10 years ago, physicians, and in particular neurologists, had a conservative, nonaggresive approach to this devastating disease. The advent of thrombolytic therapy not only proved that acute ischemic stroke is treatable, but also that early reperfusion can dramatically change the outcome of acute stroke patients.

Polyglycolide/polylactide-coated platinum coils for patients with ruptured and unruptured cerebral aneurysms: a single-center experience.

Background And Purpose: Recanalization of cerebral aneurysm is a limitation of bare platinum coils (BPCs). In a swine aneurysm model, polyglycolide/polylactide (a polymer)-coated platinum coils (Matrix) accelerated clot fibrosis and reduced recanalization rate and aneurysmal volume. We aimed to evaluate the safety of Matrix coils in patients with intracranial aneurysm.

Is transient global amnesia a risk factor for amnestic mild cognitive impairment?

Transient Global Amnesia (TGA) is a common condition of unknown aetiology characterised by the abrupt onset of severe anterograde amnesia, which lasts less than 24 hours. Some authors have suggested that subclinical impairment of memory functions may persist for much longer, but neuropsychological assessment lasting years after TGA attack has not been performed so far. The aim of this study was to evaluate longterm cognitive functions in patients with a previous TGA episode.

Is mild vascular cognitive impairment reversible? Evidence from a study on the effect of carotid endarterectomy.

Mild vascular cognitive impairment (mVCI) is a broader term that is intended to detect cognitive loss before the development of dementia. The identification of preventable risk factors as well as therapeutic strategies of intervention is still unclear. It has been suggested that carotid endarterectomy (CEA) improves cognitive functions, beyond the well-known preventive effect upon future stroke events.

Intronic CYP46 polymorphism along with ApoE genotype in sporadic Alzheimer Disease: from risk factors to disease modulators.

Increasing biological and clinical findings argue for a link between brain cholesterol turnover and Alzheimer Disease (AD), high cerebral levels of the former increasing Abeta load. Cerebral cholesterol elimination involves two mechanisms dependent on Apolipoprotein E (ApoE) and cholesterol 24-hydroxylase (CYP46). The aim of this study was to evaluate an intronic variation in CYP46 (intron 2, T --> C ) along with ApoE genotype as risk factors for AD and to establish the correlation between CYP46/ApoE polymorphism and disease progression.

Synergistic effect of apolipoprotein E polymorphisms and cigarette smoking on risk of ischemic stroke in young adults.

Background And Purpose: The effect of apolipoprotein E (APOE) polymorphisms on stroke risk may be influenced by the coexistence of modifiable predisposing conditions. We explored the interactions of APOE genotypes and conventional risk factors in a case-control study of young adults with cerebral infarct.

Methods: We analyzed 124 consecutive patients (age, 34.

Serum cholesterol levels modulate long-term efficacy of cholinesterase inhibitors in Alzheimer disease.

The clinical, genetic or biological variables which regulate long-term efficacy of cholinesterase inhibitors (ChEIs) in Alzheimer disease (AD) are still unknown and it is not possible to predict who will benefit from the treatment. In this study we showed that high cholesterol levels correlated with faster decline at 1-year follow-up in AD patients on ChEIs. These findings suggest that serum cholesterol is a modulating factor of treatment response and additional therapies aimed at reducing treatable high cholesterol levels may represent an alternative strategy to improve ChEIs efficacy and slow down disease progression over time.

Inherited thrombophilic disorders in young adults with ischemic stroke and patent foramen ovale.

Background And Purpose: The pathogenic link between patent foramen ovale (PFO) and stroke remains unknown in most cases. We investigated the association between inherited thrombophilic disorders and PFO-related strokes in a series of young adults in the setting of a case-control study.

Methods: We investigated 125 consecutive subjects (age, 34.

Microvascular damage and platelet abnormalities in early Alzheimer's disease.

Accumulating evidence from epidemiological and clinical studies suggests that vascular risk factors may be involved in Alzheimer disease (AD). Although the precise contribution of vascular disturbances to the pathogenesis of AD is still unclear, various biochemical and neuropathological data strengthen the view that cerebrovascular deficiencies such as reduced blood supply to the brain and disrupted microvascular integrity in brain parenchyma play a direct or intermediate role in the chain of events ending with a dementia syndrome. The present review focuses on platelet abnormalities and hemostatic alterations in AD.

Jugular valve incompetence: a study using air contrast ultrasonography on a general population.

Objective: Internal jugular valves are the only venous valves between the heart and the brain. Conditions such as coughing and other precipitating activities may result in retrograde cerebral venous flow because of the absence or presence of internal jugular valve incompetence, allowing brief transmission of high venous pressure and resulting in brain disturbance. Knowledge of these valves and their noninvasive evaluation might be useful in clinical practice.
