Characteristics and outcomes of large artery occlusion-related stroke due to intracranial atherostenosis: An experience from a single center in Saudi Arabia.

BACKGROUND: Literature on the frequency, response to treatment, and outcomes of acute ischemic stroke (AIS) due to intracranial atherostenosis (ICAS)-related intracranial large artery occlusion (ILAO) from Saudi Arabia is scarce. The aim of this study was to identify the percentage, describe the characteristics, and observe the treatment response in patients with AIS attributed to ICAS-related ILAO. MATERIALS AND METHODS: This cross-sectional study included all adult patients from 2017-2021 who fulfilled the inclusion criteria for the diagnosis of ICAS-related AIS. Patients were dichotomized based on ILAO. Mortality and functional outcomes (FOCs) based on 90 days' dependence level were compared between the two groups. The association between ILAO and other variables was assessed using the Chi-squared test, odds ratios (OR), and 95% confidence interval (CI). RESULTS: ILAO was found in 38.7% of patients with ICAS-related AIS. Men comprised three-fourths of the cohort and were more frequent in the ILAO group. Smoking was associated with increased (P = 0.04) likelihood of ILAO. Patients with ILAO had more severe strokes (P ≤ 0.001) than patients without. Middle cerebral artery was the most common occluded vessel (52%). Functional dependence (P = 0.003, OR = 2.87, CI = 1.42-5.77), malignant transformation (P = 0.001, OR = 8.0, CI = 1.82-35.9), and mortality (P ≤ 0.001, OR = 7.67, CI = 2.40-24.5) were significantly higher among ILAO group. Patients with ILAO with unfavorable FOC were older than those who achieved better FOC (P ≤ 0.001). Thrombolysis (P = 0.02, OR = 2.50, CI = 1.15-5.41) and mechanical thrombectomy (MT) improved FOC in patients with ILAO (P = 0.04, OR = 2.33, CI = 1.10-4.92). CONCLUSION: ILAO is common in patients with ICAS-related AIS. Timely hyperacute stroke treatment can help improve the FOC of otherwise disabling stroke due to ILAO. Raising awareness of the community about stroke is needed, so that a higher number of patients can arrive at hospital within the golden hours. Further data from the region are required to recognize the efficacy of MT in ICAS-related ILAO.

Management of patients with epilepsy and Intellectual disabilities in group homes vs. Family Homes: Insights into polypharmacy and seizure characteristics.

OBJECTIVES: This study aimed to investigate the differences in ASMs prescription, seizure characteristics and predictors of polypharmacy in patients with epilepsy and Intellectual disabilities (IDs) residing in group homes versus family homes. METHODS: This nine-year retrospective study analyzed patients with epilepsy and IDs who were admitted to the EMU, epilepsy clinics at LHSC and rehabilitation clinics for patients with IDs at Parkwood Institution. The study included individuals aged 16 years and older residing in either group homes or family homes. Data on demographics, epilepsy characteristics, and ASMs use were collected and analyzed using the Statistical Package for Social Sciences. The study utilized binary logistic regression to identify predictors of polypharmacy in patients with epilepsy and IDs. RESULTS: The study enrolled a total of 81 patients, of which 59.3 % resided in family homes. Group home residents were significantly older (41 vs. 24.5 years; p = 0.0001) and were prescribed more ASMs (3 vs. 2; p = 0.002). Specific ASMs were more common in group homes, including valproic acid (54.5 % vs. 25.0 %), lacosamide (54.5 % vs. 22.9 %), topiramate (33.3 % vs. 14.6 %), and phenytoin (30.3 % vs. 6.2 %). Admission to the EMU was more prevalent in group homes (93.9 % vs. 52.1 %; p = 0.0001). Living in a group home increased the risk of polypharmacy (OR = 10.293, p = 0.005), as did older epilepsy onset age (OR = 1.135, p = 0.031) and generalized or focal & generalized epilepsy (OR = 7.153, p = 0.032 and OR = 10.442, p = 0.025, respectively). SIGNIFICANCE: Our study identified notable differences in the demographic and clinical characteristics of patients with epilepsy and IDs living in group homes versus family homes. Age of epilepsy onset, EMU admissions, epilepsy types, and residency setting were significant predictors of polypharmacy. These findings highlight the need for personalized care strategies and increased awareness of the potential risks associated with polypharmacy.

Prevalence and Clinico-Radiologic Spectrum of Intracranial Atherosclerotic Disease-Related Stroke: An Observation from a Single Center in Saudi Arabia.

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.

Estimated prevalence study of attention-deficit/hyperactivity disorder among eastern province children in the Kingdom of Saudi Arabia.

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.

Migraine Prevalence, Characteristics, Triggers, and Coping Strategies Among Medical Students in Saudi Arabia.

Objective: To determine the prevalence, characteristics, and triggers of migraine and coping strategies used among medical students in Saudi Arabia.Methods: This cross-sectional descriptive study was conducted among undergraduate students in the College of Medicine of Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. Included students were in their second to sixth academic year of the Bachelor of Medicine or Bachelor of Surgery programs during the 2019-2020 academic year. The diagnosis of migraine was made according to the International Classification of Headache Disorders, Third Edition criteria.Results: A total of 396 students participated in the study; 238 (60.1%) were female and 158 (39.9%) were male. Their age ranged between 18 and 26 years old, with a mean age of 21.32 ± 1.659 years. Only 16 of 396 students fulfilled the criteria for migraine, with a prevalence of 4.04%. Migraine prevalence was higher in females (n = 11, 4.6%) compared to males (n = 5, 3.1%), with a female:male ratio of 1.5:1. The most common triggers associated with migraine were study-related stress (88%) and emotional-related stress (81%).Conclusions: This project was undertaken to evaluate prevalence, triggers, and coping strategies of migraine among medical students. The prevalence of migraine headache in this study was lower compared to other national and international universities, with a higher female to male ratio. Stress was a major trigger among our study population. The findings of this study will add to the growing body of literature on migraine.

An overview of complications affecting the Central Nervous System following bariatric surgery.

Bariatric surgery has been considered as an effective treatment for morbid obesity. Apart from procedures related complications, a broad spectrum of neurological disorders affecting any part of neuraxis has been reported following BS. Central nervous system complications, although less common than peripheral nervous system complications, carry significant morbidity and potential mortality. Encephalopathy, behavioral and psychiatric disorders, myelopathy and optic neuropathy are the most frequently reported CNS complications. Early detection and prompt management may improve or completely reverse these neurological complications. It is essential that the treating physicians must be aware of their clinical manifestations and management, so early diagnosis and treatment can prevent patients from suffering significant neurological deficits and even death. This review discusses the clinical manifestations of these complications in detail which will help concerned physician in earlier recognition and hence prevent the delay in specific treatment.

Relationship Between Glycated Haemoglobin and Carotid Atherosclerotic Disease Among Patients with Acute Ischaemic Stroke.

OBJECTIVES: This study aimed to determine the relationship between glycaemic control and carotid atherosclerotic disease among patients with acute ischaemic stroke (AIS). METHODS: This retrospective cross-sectional study took place in the Neurology Department of King Fahad Hospital of University, Khobar, Saudi Arabia, from April to October 2017. Data were collected from the medical records of 244 patients with a diagnosis of AIS confirmed by computed tomography. Doppler ultrasounds of the carotid artery were performed to determine the presence of increased carotid intima media thickness (CIMT) and plaques. RESULTS: Significantly higher mean glycated haemoglobin (HbA1c) levels were noted in cases with high CIMT values (P = 0.002), but not in cases with carotid plaques (P = 0.360). In addition, there was a significant association between diabetes mellitus (DM) and high CIMT (P = 0.045), but not with carotid plaques (P = 0.075). Finally, while dyslipidaemia and age were independently correlated with high CIMT values (P = 0.034 and <0.001, respectively) and carotid plaques (P <0.001 each), no independent relationships were noted in terms of gender and other risk factors like DM, hypertension and smoking (P >0.050 each). CONCLUSION: High HbA1c levels were associated with high CIMT values, but not with carotid plaques. Therefore, HbA1c levels may be useful as an indirect marker of the initial stages of carotid artery atherosclerosis.

Wernicke's encephalopathy following Roux en Y gastric bypass surgery.

Wernicke's encephalopathy (WE) is a serious neurological disorder characterized by a classical triad of acute mental confusion, ataxia, and opthalmoplegia due to thiamine deficiency. It was initially described in chronic alcoholics; however, any condition resulting in poor nutritional status places the patient at risk of WE. Bariatric surgery is now considered as an emergent cause of WE. The number of bariatric surgery is increasing for morbid obesity. We present a case of a 40-year-old male who presented with confusion and difficulty in maintaining the balance while walking 3 months after Roux en Y gastric bypass surgery. Diagnosis of WE was made on clinical ground and confirmed by magnetic resonance imaging of the brain, which showed bilateral hyperintense signals in paramedian thalami. Parenteral thiamine replacement was started, and patient showed complete recovery.
