RESUMO

BACKGROUND: The occurrence of seizures following a stroke is a well-recognized complication associated with a significant increase in morbidity and mortality. Despite the numerous studies examining outcomes and risk factors related to post-stroke seizures (PSS), there remains a lack of clarity regarding the clinical characteristics, treatment, and PSS recurrence (PSSR) rates in patients experiencing their initial episode of PSS. PURPOSE: This study aimed to determine the risk factors for developing recurrent seizures after first PSS and their effects on functional outcomes and mortality. METHODS: All patients underwent an electroencephalography (EEG) and were monitored for a minimum of 24 months following the first PSS. The primary endpoint was the recurrence of seizures. Predictive factors for PSSR were determined by using the Cox-proportional hazards model, and the cumulative latency of recurrence at 90, 180, 360, and 720 days was estimated using Kaplan-Meier analysis. RESULTS: Seizure recurred in 36.8% (39/106). Significant association of PSSR was noted with female gender, use of older anti-seizure medications (ASMs) (p<0.001), EEG findings as focal slow wave activity (p<0.001), Ictal epileptiform abnormalities (p=0.015), status epilepticus (p=0.015), and with severe disability (p=0.008). However, multivariate cox-proportional hazards model showed significant association of female gender (HR=3.28; 95% CI: 1.42-7.58; p=0.006). Hazard ratio (HR) was increased with older ASMs use, focal aware seizure types, Ictal EAs, and periodic discharges on EEG; though, statistically significant. CONCLUSION: Factors such as the type of ASMs, EEG findings, and seizure type were significantly linked to PSSR. Female gender was the only independent predictor established. Additionally, significant functional decline was reported with recurrence.

RESUMO

Introduction: Guillain-Barré syndrome (GBS) is a rare disease that affects almost 0.8-1.9 cases per 100,000 people worldwide every year. This is the most prevalent cause of subacute flaccid paralyzing illness today. It is a subacute inflammatory demyelinating polyradiculoneuropathy; the typical scenario involves ascending symmetrical flaccid paralysis, but in some circumstances, sensory, autonomic, and cranial neuropathy may also be involved. Several vaccines have been found to have complications since the previous century. Numerous case reports of GBS in the literature have been reported following COVID-19 vaccines in recent times. Objective: This study aimed to conduct a comprehensive examination of GBS cases that have been reported after COVID-19 vaccines; to analyze the descriptive statistical analysis of data gathered regarding clinical, laboratory, electrophysiological, and radiological characteristics; to discuss, based on the available evidence, whether the disease has a preference for a particular vaccine type; and to speculate on the potential pathogenesis. Methodology: This review has been carried out by recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Result: Reviewing 60 case reports illustrated that most of them are from the USA (18.1%) and the majority of affected individuals were males (60%). The results favored the association between vector-based SARS-CoV-2 vaccine, particularly AstraZeneca vaccine, and the GBS. The mean of symptoms onset is 11.4 days. The results of diagnostic tests such as LP are consistent mostly with albumin-cytological dissociation (81.81%), where brain and spine MRI was unremarkable in 59.52%. Regarding electrodiagnostic tests, AIDP is the most common variant (61.81%). The management was not consistent among the case reports. However, IVIG is the most frequent way of treating these patients (68.33%). The functional outcome was documented in 47 patients; 65% improved with medical management. Conclusion: This study aimed to conduct a systematic review of reported cases of GBS following COVID-19 vaccines and descriptive statistical analysis of collected data on clinical, laboratory, electrophysiological, and radiological features, to discuss, based on available results, whether the disease has a predilection to a specific vaccine type and to speculate the potential pathogenesis.

RESUMO

Objective: Post-stroke seizures (PSS) are one of the major stroke-related complications. Early therapeutic interventions are critical therefore using electroencephalography (EEG) as a predictive tool for future recurrence may be helpful. We aimed to assess frequencies of different EEG patterns in patients with PSS and their association with seizure recurrence and functional outcomes. Methods: All patients admitted with PSS were included and underwent interictal EEG recording during their admission and monitored for seizure recurrence for 24 months. Results: PSS was reported in 106 patients. Generalized slow wave activity (GSWA) was the most frequent EEG pattern observed (n = 62, 58.5%), followed by Focal sharp wave discharges (FSWDs) (n = 57, 55.8%), focal slow wave activity (FSWA) (n = 56, 52.8%), periodic discharges (PDs) (n = 13, 12.3%), and ictal epileptiform abnormalities (n = 6, 5.7%). FSWA and ictal EAs were positively associated with seizure recurrence (p < .001 and p = .015 respectively) and it remained significant even after adjusting for age, sex, stroke severity, stroke subtype, or use of anti-seizure medications (ASMs). Other positive associations were status epilepticus (SE) (p = .015), and use of older ASM (p < .001). FSWA and GSWA in EEG were positively associated with severe functional disability (p = .055, p = .015 respectively). Other associations were; Diabetes Mellitus (p = .034), Chronic Kidney Disease (p = .002), use of older ASMs (p = .037), presence of late PSS (p = .021), and those with Ischemic stroke (p = .010). Conclusions: Recognition and documentation of PSS-related EEG characteristics are important, as certain EEG patterns may help to identify the patients who are at risk of developing recurrence or worse functional outcomes.

RESUMO

Objective: This study aimed to investigate the effect of the glycated hemoglobin A1c (HbA1c) level on the functional outcome (FOC) in patients with intracranial large artery atherosclerotic disease (ICLAD)-related acute ischemic stroke (AIS). Methods: This retrospective study enrolled patients with ICLAD-related AIS who were admitted to King Fahd University Hospital between January 2017 and September 2021. Patients were divided into two groups based on the optimal cutoff HbA1c level determined using receiver operating characteristic curve analysis-those with HbA1c ≤6.9% and those with HbA1c >6.9%. Demographic and other clinical characteristics were compared between the two groups using chi-square tests. The association between HbA1c and 90-day FOC was assessed using the chi-square test and odds ratios (ORs). Multivariate analysis was performed to adjust for confounding factors. Results: A total of 140 patients were included in the analysis. A significant association was observed between the HbA1c level and FOC. Compared to patients with HbA1c ≤6.9%, patients with HbA1c >6.9% were more likely to have an unfavorable FOC [p = <0.001, OR = 2.05, 95% confidence interval (CI) = 1.33-3.14]. The association between HbA1c >6.9% and unfavorable FOC was sustained even after adjusting for confounding factors (p = 0.008) and atherosclerosis risk factors (p = 0.01). HbA1c >6.9% was also associated with higher ORs for in-hospital complications (p = 0.06, OR = 1.34, 95% CI = 1.02-1.77) and mortality (p = 0.07, OR = 1.42, 95% CI = 1.06-1.92) although these associations did not attain significant p-values. Conclusion: HbA1c >6.9% was significantly associated with unfavorable FOC in ICLAD-related AIS. However, further studies with larger sample sizes are required to verify whether HbA1c is an independent predictor of poor FOC. Nevertheless, targeting HbA1c <7% should be the goal of physicians when managing patients at high risk of ICLAD.

RESUMO

Ischemic stroke represents a significant societal burden across the globe. Rare high penetrant monogenic variants and less pathogenic common single nucleotide polymorphisms (SNPs) have been described as being associated with risk of diseases. Genetic studies in Saudi Arabian patients offer a greater opportunity to detect rare high penetrant mutations enriched in these consanguineous populations. We performed whole exome sequencing on 387 ischemic stroke subjects from Saudi Arabian hospital networks with up to 20,230 controls from the Saudi Human Genome Project and performed gene burden analyses of variants in 177 a priori loci derived from knowledge-driven curation of monogenic and genome-wide association studies of stroke. Using gene-burden analyses, we observed significant associations in numerous loci under autosomal dominant and/or recessive modelling. Stroke subjects with modified Rankin Scale (mRSs) above 3 were found to carry greater cumulative polygenic risk score (PRS) from rare variants in stroke genes (standardized PRS mean > 0) compared to the population average (standardized PRS mean = 0). However, patients with mRS of 3 or lower had lower cumulative genetic risk from rare variants in stroke genes (OR (95%CI) = 1.79 (1.29-2.49), p = 0.0005), with the means of standardized PRS at or lower than 0. In conclusion, gene burden testing in Saudi stroke populations reveals a number of statistically significant signals under different disease inheritance models. However, interestingly, stroke subjects with mRS of 3 or lower had lower cumulative genetic risk from rare variants in stroke genes and therefore, determining the potential mRS cutoffs to use for clinical significance may allow risk stratification of this population.

RESUMO

BACKGROUND: Intracranial atherosclerotic disease (ICAD) is an important etiologic subtype of acute ischemic stroke (AIS). However, little direct evidence is available regarding ICAD-related stroke in Saudi Arabia (SA). This study aimed to identify the prevalence and describe the clinico-radiological spectrum of ICAD-related AIS in a SA cohort. METHODS: This was a hospital-based retrospective study enrolling patients with ICAD-related AIS between 2017 and 2020. The electronic charts were reviewed. The mechanisms of stroke were identified as artery-to-artery embolization (AAE), in situ thrombotic occlusion, hypoperfusion, or perforator branch occlusion. Pearson's χ 2 test was performed to calculate the P values to establish the statistical significance of factors that could correlate with the mechanisms of stroke and functional outcome. RESULTS: ICAD was found in 133 of AIS comprising 26% of total. Data from all patients were reviewed. Left ICA (25%) was the most frequently affected vessel. Territorial pattern (63.9%) was the most common infarct pattern, and AAE (44.3%) was the most common underlying mechanism. Perforator branch occlusion was more prevalent in women than in men. Malignant and hemorrhagic transformation ( P =0.00) were more prevalent in the AAE group. Left-sided vascular involvement was statistically associated with unfavorable outcomes than the right ( P =0.019). CONCLUSIONS: The prevalence of ICAD in our cohort from Western Asia did not differ from that in Southern Asia. ICA involvement was observed more frequently than previously reported. Further research from SA is required to better understand ICAD-related strokes in this region.

RESUMO

Background: Studying mental disorders in children is significantly important due to the huge suffering of educational and psychosocial impairments in adult life. Attention-deficit/hyperactivity disorder (ADHD) is considered the most common mental disorder in children, especially in early school-aged children. It manifests in about 8%-12% of children in the world. In Saudi Arabia, it affects 4%-12% of children. Objective: The study aimed to count the number of undiagnosed ADHD cases and the associated risk factors in Eastern Province in Kingdom of Saudi Arabia (KSA). Methods: A cross-sectional study was performed among girls' and boys' children aged 6-10 years old in Eastern Province in KSA with a random selection of parents. Sample size is equal to 1658. The assessment was done by an online questionnaire filled it by parents using Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition diagnostic criteria and Connor's scale of ADHD excluding any developmental or mental disorder at the beginning of the questionnaire. Results: After excluding the participants who were diagnosed with behavioral and growth developmental disorder, the remaining 1430 have been screened for ADHD based on Connor's scale. 185 of a child out of 1430 were suggested to have ADHD, of which 10 out of them show the signs of ADHD, 76 of them have moderately severe ADHD, and 99 out of them have atypical or severe ADHD based on Connor's scale of ADHD. The study shows that there is a significant relationship between the positive screening of ADHD and gender males (71.35%), females (28.64%), family history (20.5%), nervous system diseases (4.32%), brain damage from trauma (9.72%), smoking habit of the mother (8.64%), smoking during pregnancy (3.78%), mother exposure to second-hand smoking (42.16%), child exposure to a toxic substance like lead during the early life (1.62%), and the preterm labor (15.13%). However, the study shows there is no significant relationship between the positive screening of ADHD with age, drinking alcohol, and central nervous system infection. Conclusion: The prevalence of undiagnosed ADHD is slightly high. Also, it has many causes of ADHD including gender, smoking, parental psychiatric disorders, and obstetric and pregnancy problems.


Résumé Background: L'étude des troubles mentaux chez les enfants est d'une importance considérable en raison des souffrances liées aux difficultés scolaires et psychosociales qui perdurent à l'âge adulte. Le trouble du déficit de l'attention avec hyperactivité (TDAH) est considéré comme le trouble mental le plus courant chez les enfants, notamment chez les enfants d'âge scolaire précoce. Il se manifeste chez environ 8% à 12% des enfants dans le monde. En Arabie saoudite, il touche entre 4% et 12% des enfants. Objective: L'étude visait à dénombrer le nombre de cas de TDAH non diagnostiqués et les facteurs de risque associés dans la province orientale du Royaume d'Arabie saoudite (KSA). Methods: Une étude transversale a été réalisée auprès d'enfants de filles et de garçons âgés de 6 à 10 ans dans la province orientale de l'Arabie saoudite, en utilisant une sélection aléatoire des parents. La taille de l'échantillon est égale à 1658. L'évaluation a été réalisée à l'aide d'un questionnaire en ligne rempli par les parents, en utilisant les critères diagnostiques du Manuel diagnostique et statistique des troubles mentaux, cinquième édition, ainsi que l'échelle de Connor pour le TDAH, en excluant tout trouble du développement ou trouble mental au début du questionnaire. Résultats: Après exclusion des participants ayant été diagnostiqués avec un trouble du comportement et du développement, les 1430 restants ont été dépistés pour le TDAH à l'aide de l'échelle de Connor. Parmi ces enfants, 185 ont été suggérés d'avoir un TDAH, dont 10 présentent des signes de TDAH, 76 présentent un TDAH modérément sévère et 99 présentent un TDAH atypique ou sévère selon l'échelle de Connor. L'étude révèle qu'il existe une relation significative entre le dépistage positif du TDAH et le genre masculin (71,35 %), féminin (28,64 %), les antécédents familiaux (20,5 %), les maladies du système nerveux (4,32 %), les lésions cérébrales suite à un traumatisme (9,72 %), la consommation de tabac par la mère (8,64 %), la consommation de tabac pendant la grossesse (3,78 %), l'exposition de la mère à la fumée secondaire (42,16 %), l'exposition de l'enfant à une substance toxique comme le plomb pendant la petite enfance (1,62 %) et le travail prématuré (15,13 %). Cependant, l'étude montre qu'il n'existe aucune relation significative entre le dépistage positif du TDAH et l'âge, la consommation d'alcool et les infections du système nerveux central. Conclusion: La prévalence du TDAH non diagnostiqué est légèrement élevée. De plus, il existe de nombreuses causes du TDAH, dont le genre, le tabagisme, les troubles psychiatriques des parents, ainsi que les problèmes obstétriques et durant la grossesse.

RESUMO

Migraine, as the seventh most disabling neurological disease with 26.9% prevalence in Saudi females, lacks studies on identifying associated genes and pathways with migraines in the Arab population. This case control study aims to identify the migraine-associated novel genes and risk variants. More than 1900 Arab ancestry young female college students were screened: 103 fulfilled the ICHD-3 criteria for migraine and 20 cases confirmed in the neurology clinic were included for the study with age-matched healthy controls. DNA from blood samples were subjected to paired-end whole-exome sequencing. After quality control, 3365343 missense, frameshift, missense splice region variants and insertion-deletion (indels) polymorphisms were tested for association with migraine. Significant variants were validated using Sanger sequencing. A total of 17 (p-value 9.091 × 10-05) functional variants in 12 genes (RETNLB, SCAI, ADH4, ESPL1, CPT2, FLG, PPP4R1, SERPINB5, ZNF66, ETAA1, EXO1 and CPA6) were associated with higher migraine risk, including a stop-gained frameshift (-13-14*SX) variant in the gene RETNLB (rs5851607; p-value 3.446 × 10-06). Gene analysis revealed that half of the significant novel migraine risk genes were expressed in the temporal lobe (p-value 0.0058) of the cerebral cortex. This is the first study exploring the migraine risk of 17 functional variants in 12 genes among Saudi female migraineurs of Arab ancestry using whole-exome sequencing. Half of the significant genes were expressed in the temporal lobe, which expands migraine pathophysiology and early identification using biomarkers for research possibilities on personalised genetics.

RESUMO

Background and Objective: Regeneration of nervous tissue is unpredictable and an ideal growth factor to influence the healing of the injured nerves is not available. A recent study in rats had shown that a new neuronal growth factor (NNGF) was effective in the early healing of the sciatic nerves. The aim of this experimental study is to test the efficacy of NNGF in the healing of iatrogenic division of the sciatic nerves in a larger animal (rabbits). Methods: White New Zealand 20 male rabbits of 6 months of age were divided into two groups. Intramuscular ketamine and xylazine were used to anesthetize the animals. The sciatic nerves were divided using scalpel blade 15 and 10/0 Vicryl was used to repair the divided neural tissue. In the study group, 10 mg/kg body weight of NNGF was instilled on the top of the divided nerves and the wound was closed. At 4 weeks, the operated limbs were observed for any trophic skin changes. Nerve conduction studies were carried out using train-of-four-Watch SX, Organon (Ireland) Ltd., and Ireland. The rabbits were put to death humanely and the sciatic nerves were removed and delivered to the pathologist in 2% formalin. The pathologists were blinded about the two groups. Results: Electromyographic study done at 4 weeks showed in the untreated group; the mean twitches 1-T4 was 0.45 ± 0.31% and in the treated group, the average was 77.912 ± 5% (P > 0.001). Microscopic anatomy in the treated group revealed prominent healing by regeneration was evidenced by showing growth of its proximal segments into an empty endoneurial tube which was not seen in the control group. In the control group, the nerves showed no histological element of healing by regeneration. Conclusions: NNGF proves that in a larger animal at 4 weeks profoundly influenced early regeneration of experimentally created divisions of myelinated nerve tissue.


Résumé Contexte et objectif: La régénération des tissus nerveux est imprévisible et un facteur de croissance idéal pour influencer la guérison des nerfs blessés n'est pas disponible. Une étude récente chez le rat a montré qu'un nouveau facteur de croissance neuronal (NNGF) était efficace dans la guérison précoce des nerfs sciatiques. L'objectif de cette étude expérimentale est de tester l'efficacité du NNGF dans la guérison de la division iatrogène des nerfs sciatiques chez un animal plus grand (lapin). Méthodes: White New Zealand 20 lapins mâles de 6 mois ont été divisés en deux groupes. La kétamine intramusculaire et la xylazine ont été utilisées pour anesthésier les animaux. Les nerfs sciatiques ont été divisés en utilisant la lame scalpel 15 et 10/0 vicryl ont été utilisés pour réparer le tissu neural divisé. Dans le groupe d'étude, 10 mg / kg de poids corporel du NNGF ont été inculqués sur le dessus des nerfs divisés et la plaie a été fermée. À 4 semaines, les membres opérés ont été observés pour tout changement de peau trophique. Des études de conduction nerveuse ont été menées à l'aide de SX Train-of-Nat-Watch, Organon (Ireland) Ltd. et Ireland. Les lapins ont été mis à mort avec humanité et les nerfs sciatiques ont été retirés et livrés au pathologiste dans 2% de formol. Les pathologistes ont été aveuglés sur les deux groupes. Résultats: électromyographique L'étude réalisée à 4 semaines a montré dans le groupe non traité; Les contractions moyennes 1 à T4 étaient de 0,45 ± 0,31% et dans le groupe traité, la moyenne était de 77,912 ± 5% (p> 0,001). L'anatomie microscopique dans le groupe traité a révélé une guérison importante par régénération a été mise en évidence en montrant la croissance de ses segments proximaux dans un tube endoneurial vide qui n'a pas été observé dans le groupe témoin. Dans le groupe témoin, les nerfs n'ont montré aucun élément histologique de guérison par régénération. Conclusions: NNGF prouve que chez un animal plus grand à 4 semaines, a profondément influencé la régénération précoce des divisions créées expérimentalement du tissu nerveux myélinisé. Mots-clés: Facteurs de croissance, régénération nerveuse, nerfs sciatiques.

RESUMO

Objective: Wake-up stroke (WUS) comprises a significant proportion of ischemic strokes. However, due to unclear onset, these patients are often not considered for reperfusion therapy. The objective of this study was to investigate the clinical and imaging differences between WUS patients and those with clear-onset stroke, documenting any sex, age, or risk factor predilection for WUS.Methods: This prospective observational cohort study used an ongoing stroke registry to identify patients with acute ischemic stroke admitted to a hospital in Saudi Arabia within 5 days of symptom onset from April 2018 to March 2020. Patients were classified into 2 groups: WUS and clear-onset stroke.Results: Among 645 patients, 448 met the criteria for acute ischemic stroke and were included in the study. WUS was identified in 112 (25%) patients. There were no differences in sex or median age between the 2 groups. Diabetes mellitus, hypertension, and dyslipidemia were higher in the WUS group, while atrial fibrillation, history of stroke and epilepsy were higher in the clear-onset stroke group. Bihemispheric stroke was higher in the clear-onset stroke group than in the WUS group (6.0% vs 2.7%).Conclusions: Only minor dissimilarities between clinical and radiologic features of WUS and clear-onset stroke were found. Circadian patterns of stroke onset were observed in both groups. Stroke was more likely to occur during waking than during sleep, and a diurnal pattern of common occurrence during the morning was documented. Recognition of the acceptable timeframe for acute reperfusion therapy in unwitnessed strokes is crucial so that thrombolytic treatment can be started for these patients.

RESUMO

Background: Mitochondrial DNA (mtDNA) mutations have been reported in multiple neurological diseases and helped to explain the pathophysiology of these diseases. Similarly, variations in mtDNA might exist in migraine and can explain the effect of low ATP production in the neurons on the initiation of migraine attack. Therefore, in the current study we aim to explore the association of mtDNA mutations on migraine in the Saudi population. Subjects and Methods: Over 1950 young Saudi female students were screened for migraine, among that a total of 103 satisfied the ICHD-3 criteria. However,  20 migraine cases confirmed in the neurology clinic and gave consent to participate in the study. Another 20 age-matched healthy controls were also recruited. Mitochondrial sequence variations were filtered from exome sequencing using NCBI GenBank Reference Sequence: NC_012920.1 and analysed using MITOMAP. Genes with significant single nucleotide polymorphisms (SNPs) were investigated by the gene functional classification tool DAVID and functional enrichment analysis of protein-protein interaction networks through STRING 11.5 for the most significant associated genes. Results: Genome wide analysis of the mitochondrial sequence variations between the patients with migraine and control revealed the association of 30 SNPs (p < 0.05) in the mitochondrial genome. The highest significance (p = 0.001033) was observed in a coding SNP (rs1603225278) in the CYTB gene and rs386829281 in the region of origin of replication. Twenty-four significant SNPs were in the coding region of nine (ND5, ND4, COX2, COX1, ND3, CYTB, COX3, ND2 and ND1) genes. Conclusion: This is the first study to demonstrate the association of mtDNA variations with migraine in the Saudi population. The current findings will help to highlight the significance of mtDNA mutations to migraine pathophysiology and will serve as a reference data for larger national and international studies.

RESUMO

Objective: To compare cardiovascular risk factors in patients with epilepsy with those of non-epileptic neurologic patients to determine their association with antiepileptic drug therapy.Methods: This observational study with a cross-sectional design was performed in a tertiary care hospital in the Eastern Province of Saudi Arabia from January to December 2018. A total of 110 patients with epilepsy were included in the study, along with 46 age- and sex-matched non-epileptic controls (approximate ratio of 2:1). Blood pressure reading (BP), anthropometric measurements, fasting blood sugar levels, and fasting lipid profiles were performed for all subjects.Results: Raised non-high-density lipid cholesterol (nHDLC) was the most common cardiovascular risk in epileptic patients, with a frequency of 51% compared to 30.4% in controls (P = .019). Epileptic patients who were male (58.3%, 28/48, P = .012) and those aged < 35 years (47.3%, 26/55, P = .036) were more likely to have high nHDLC. Obesity was also common in epileptic patients with frequency of 49.1% (n = 54) versus 30.4% (n = 14) in controls (P = .032). Metabolic syndrome was present in 26.3% of epileptic patients versus 23.9% of controls (P = .749). Among the epileptic patients, of those with high nHDLC, 85.7% had satisfactory seizure control (P = .019).Conclusions: Raised nHDLC and obesity but not metabolic syndrome appear to be highly prevalent in epileptic patients compared to those without epilepsy. Antiepileptic drugs alone may not play a role in developing high lipid levels. More studies are needed to determine the causes of higher risk factor profile in epileptic patients and their relationship with seizure control.

RESUMO

Pompe disease is a rare, metabolic, autosomal recessive disorder. Early diagnosis is critical for progressive Pompe disease as delays can significantly alter the clinical course of the disease. Diagnostic modalities, including dried blood spot testing and genetic testing, are available and are effective for diagnosing patients with late-onset Pompe disease (LOPD). However, clinicians face numerous clinical challenges related to the diagnosis of the disease. Two expert group committee meetings, involving 11 experts from the United Arab Emirates, Kuwait, the Kingdom of Saudi Arabia, and Oman, were convened in October 2019 and November 2020 respectively to develop a uniform diagnostic algorithm for the diagnosis of pediatric and adult LOPD in the Arabian Peninsula region. During the first meeting, the specialty-specific clinical presentation of LOPD was defined. During the second meeting, a diagnostic algorithm was developed after a thorough validation of clinical presentation or symptoms, which was performed with the aid of existing literature and expert judgement. A consensus was reached on the diagnostic algorithm for field specialists, such as neurologists, rheumatologists, general practitioners/internal medicine specialists, orthopedic specialists, and pulmonologists. This specialty-specific diagnostic referral algorithm for pediatric and adult LOPD will guide clinicians in the differential diagnosis of LOPD.

RESUMO

Background: Spontaneous simultaneous bilateral basal ganglia hemorrhage (SSBBGH) is an extremely rare condition with only a few published case reports and series. However, there is no systematic review that has been published yet. Objective: The study aims to conduct a systematic review on spontaneous simultaneous bilateral basal ganglion bleeding and a descriptive statistical analysis of collected data on epidemiology, clinical features, etiology, therapeutic approach and prognosis. This review aims to be a clinical reference for busy clinicians when they are faced with such a rare condition. Methodology: This review has been carried out in accordance with recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Results: Review of 60 cases showed that SSBBGH affected predominantly male patients (70%) with an average age of 50.8 ± 15.33 years and the male-to-female ratio was 2.5:1. The female patients tend to be older with an average age of 54.22 ± 16.67 years. Location of SSBBGHwas more common in the putamen (90% vs 10% non-putaminal). SSBBGH posed a significant mortality rate (33.33%). Among patients who survived, only 40.6% (13/32 report) have had favorable outcomes (mRS ≤2) and the remaining 59.4% (19/32) ended up with poor functional status (mRS ≥3-5). The most common implicated etiologies were hypertension followed by alcohol intoxication. Conclusion: SSBBGH is a rare clinical entity with significant morbidity and mortality. Systemic approach can lead to early recognition of etiology and prompt treatment. Hypertension and the putamen are the most common etiology and location of SSBBGH, respectively. History of hypertension and age can help narrow differential diagnosis and limit unnecessary testing or intervention.

RESUMO

Objective: Patients with epilepsy are instructed to avoid high-risk situations such as certain occupations and driving to prevent harm to themselves and others. There is considerable variation in standards to decide if a patient with epilepsy is fit to drive among various countries worldwide, and these patients often continue to drive despite being advised not to. The objective of this study was to determine if patients with epilepsy and uncontrolled epilepsy are driving, the awareness of epilepsy patients regarding driving, and whether physicians are advising the patients to stop driving.Methods: A clinic-based study was conducted in Saudi Arabia from June 2018 through January 2019 with structured interviews of consecutively recruited male patients with established epilepsy diagnosis. Demographic factors, employment status, control of seizures, and awareness of driving restrictions were documented.Results: The response rate was 80.6%. Of the 121 participants (mean age of 35.97 years), 110 (90.9%) were driving, and 39% of those patients were married. Also, 76.9% of participants were employed. Of the participants, 48.8% had 1 seizure in the last 6 months, and 88% of those patients were driving; 51.2% had not had a seizure in the last 6 months, and 93% of those patients were driving. Additionally, 17.4% reported a seizure attack while driving. Only 38% of respondents were aware they should stop driving, whereas 62% were unaware of driving restrictions.Conclusions: There is a definite need to establish a driving policy for patients with epilepsy and to optimize the standards of care of epilepsy patients in Saudi Arabia to ensure minimization of harm to both patients and the public.

RESUMO

Autism is a complex disease with genetic predisposition factors. Real factors for treatment and early diagnosis are yet to be defined. This study integrated transcriptome and exome genotyping for identifying functional variants associated with autism spectrum disorder and their impact on gene expression to find significant variations. More than 1800 patients were screened, and 70 (47 male/23 female) with an average age of 7.56 ± 3.68 years fulfilled the DSM-5 criteria for autism. Analysis revealed 682 SNPs of 589 genes significantly (p < 0.001) associated with autism among the putative functional exonic variants (n = 243,345) studied. Olfactory receptor genes on chromosome 6 were significant after Bonferroni correction (α = 0.05/243345 = 2.05 × 10-7) with a high degree of linkage disequilibrium on 6p22.1 (p = 6.71 × 10-9). The differentially expressed gene analysis of autistic patients compared to controls in whole RNA sequencing identified significantly upregulated (foldchange ≥0.8 and p-value ≤ 0.05; n = 125) and downregulated (foldchange ≤-0.8 and p-value ≤ 0.05; n = 117) genes. The integration of significantly up- and downregulated genes and genes of significant SNPs identified regulatory variants (rs6657480, rs3130780, and rs1940475) associated with the up- (ITGB3BP) and downregulation (DDR1 and MMP8) of genes in autism spectrum disorder in people of Arab ancestries. The significant variants could be a biomarker of interest for identifying early autism among Arabs and helping to characterize the genes involved in the susceptibility mechanisms for autistic subjects.

RESUMO

Introduction: Migraine is a highly prevalent condition, and prevalence of obesity is also increasing. Results of studies addressing association of body mass index (BMI) with migraine and its features are conflicting. In this cross-sectional study, we aim to assess association between BMI and various migraine features. Methods: This study was conducted in the Headache Clinic of King Fahd Hospital of University, Al Khobar, Saudi Arabia. Interviews were conducted by three consultant neurologists. Migraine was defined according to the International Headache Society and BMI was calculated as weight (kilograms)/height (m2). Results: Of total of 121 patients, 79% were female. Almost 87.6% of patients were taking prophylactic medications. Majority of patients had attack for more than 24 h (60.3%), pulsating character (81%), moderate-to-severe intensity (92.6%), associated with nausea and/or vomiting (75.2%), and photophobia/phonophobia (91.7%). About 29.8% of patients were normal weight, 28.1% were overweight, and 39.7% were obese and morbidly obese. There was insignificant association between various categories of BMI and features of migraine, that is, unilateral location (P = 0.385), pulsating character (P = 0.571), moderate-to-severe intensity (P = 0.187), nausea and/or vomiting (P = 0.582), and photophobia and/or phonophobia (P = 0.444). Conclusion: In our study, we did not find an association between BMI and various features of migraine.


RésuméIntroduction: La migraine est une maladie très répandue, et la prévalence de l'obésité est également en augmentation. Résultats des études portant sur l'association de l'indice de masse corporelle (IMC) avec la migraine et ses caractéristiques sont contradictoires. Dans cette étude transversale, nous visons à évaluer l'association entre IMC et diverses caractéristiques de la migraine. Méthodes: Cette étude a été menée à la Headache Clinic de l'hôpital King Fahd de l'Université, Al Khobar, Arabie Saoudite. Les entretiens ont été menés par trois neurologues consultants. La migraine a été définie selon l'International La Headache Society et l'IMC ont été calculés en poids (kilogrammes)/taille (m2). Résultats: Sur un total de 121 patients, 79 % étaient des femmes. Presque 87,6 % des patients prenaient des médicaments prophylactiques. La majorité des patients ont eu une attaque pendant plus de 24h (60,3%), caractère pulsatile (81%), intensité modérée à sévère (92,6 %), associée à des nausées et/ou vomissements (75,2 %) et photophobie/phonophobie (91,7 %). Environ 29,8 % des les patients avaient un poids normal, 28,1 % étaient en surpoids et 39,7 % étaient obèses et obèses morbides. Il y avait une association insignifiante entre diverses catégories d'IMC et caractéristiques de la migraine, c'est-à-dire localisation unilatérale (P = 0,385), caractère pulsatile (P = 0,571), modéré à sévère intensité (P = 0,187), nausées et/ou vomissements (P = 0,582) et photophobie et/ou phonophobie (P = 0,444). Conclusion: Dans notre étude, nous n'ont pas trouvé d'association entre l'IMC et diverses caractéristiques de la migraine.

RESUMO

OBJECTIVES: To assess prevalence and perception of sleep paralysis and its relationship with socioeconomic determinants, and risk factors in a cross-sectional sample of Saudi general population from Al-Ahsa city. METHODS: A cross-sectional sampling survey was conducted during 2020 to 2021. The targets were aged above 18 and belonged to Al-Ahsa. Patients were sent self-reported anonymous questionnaires to complete. RESULTS: A total of 524 participants, whose ages ranged from 18 to 60 years, were analyzed. Among 85.7% of participants aged 55 years and over, compared to 65.8% of those who were aged under 35, 379 (72.3%) respondents were females. Moreover, 438 (83.6%) participants were university graduates, 271 (51.7%) were students and 40.8% had psychological disorders including anxiety (25.2%) and depression (5.7%). Family history of sleep paralysis was reported by 369 (70.4%) participants. A total of 97.5% study participants were aware of sleep paralysis. CONCLUSION: Sleep paralysis is a common occurrence in people residing in Al-Ahsa, Saudi Arabia. A considerable number of the society held wrong beliefs regarding sleep paralysis. Therefore, raising public of identity of sleep paralysis is crucial. We recommend applying the study in other cities within Saudi Arabia to identify common risk factors and perceptions among the society.

RESUMO

Objective: To determine the etiologies of epilepsy in a cohort of patients using the International League Against Epilepsy 2017 classification system and to determine frequencies of preventable causes and their clinical characteristics.Methods: Epileptic patients in neurology clinics at a tertiary care hospital were prospectively recruited from June 1, 2018, to November 30, 2018. Patients were divided according to their respective etiologic categories. Traumatic brain injury, stroke, hypoxic-ischemic encephalopathy, and central nervous system infections were considered preventable etiologies.Results: A total of 160 patients were included in the study. Of these patients, 61 had epilepsy of unknown etiology, while among the remaining 99 patients in whom etiology could be identified, traumatic brain injury was the most frequent overall cause with 17 (17.2%) cases. Frequencies in other etiologies were genetic (idiopathic generalized epilepsy): n = 14, stroke: n = 13, hypoxic-ischemic encephalopathy: n = 13, cerebral tumors: n = 10, mesial temporal sclerosis: n = 9, cortical malformation: n = 7, and other structural pathologies: n = 5. Other rarer causes (including central nervous system infections) had less than 5 patients each. When the preventable etiologies were grouped, they formed 46 of 99 patients (46.5%) with identifiable etiology. Seizure control was mostly satisfactory in the total sample (126/160 [78.8%]), including patients with preventable etiologies, of whom 50% were on polytherapy.Conclusions: Epilepsies with preventable etiologies are common in our clinics. Studies are needed in other centers to identify epilepsy etiologies and confirm our findings, which may help determine better strategies for primary prevention of epilepsy.

RESUMO

Objective: To compare the safety and efficacy of conventional anticoagulants with new oral anticoagulants (NOACs) for management of cerebral venous sinus thrombosis (CVST).Methods: This was a retrospective, prospective cohort study of patients who presented with CVST to a tertiary stroke center in the Middle East from January 2012 to October 2019. Patients with a diagnosis of CVST were identified, and data were analyzed for demographic characteristics. Specific consideration was given to compare the efficacy and safety of different anticoagulation treatments.Results: A total of 36 patients were included in the final analysis, with 15 (41%) men and 21 (59%) women and a male to female ratio of 1:1.4. Most of the patients (n = 22, 61%) were Saudi. Their ages ranged between 15 and 82 years (mean ± SD age of 34.22 ± 13.16 years). Headache was the most common feature, present in 22 (61%) of the patients, followed by unilateral weakness in 15 (41%) and cranial nerve palsies in 11 (30%). The most common etiology was prothrombotic state (both hereditary and acquired thrombophilia: n = 16, 45%). Other etiologies were postpartum state/oral contraceptive pill usage in 7 (19%), infections in 7 (19%), and trauma in 3 (8%). Most of the patients (n = 24, 67%) still received conventional anticoagulation (warfarin/low molecular weight heparin), but 9 (25%) of the patients consented to start NOACs. Efficacy (as measured by clinical improvement plus rate of recanalization of previously thrombosed venous sinuses) showed no statistically significant difference, although it proved to be better tolerated, as none of the patients stopped the treatment due to adverse events and risk of major bleeding was significantly low in the NOAC group. Nine patients in the warfarin group stopped medication, while none in the NOAC group did so (P = .034).Conclusion: NOACs were found to be at least as good as conventional anticoagulation for the management of CVST. However, efficacy was almost similar, a finding that is consistent with most of the published case series and the few recently published prospective studies. Larger prospective and population-based studies are needed to clarify our preliminary results.
