Association between glycated hemoglobin and functional outcomes in patients with intracranial large artery atherosclerotic disease-related acute ischemic stroke: identifying the magic number.

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.

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.

No evidence of disease activity-3 (NEDA-3) status in patients with relapsing remitting multiple sclerosis: Evidence from Saudi cohort receiving mainly Interferon.

BACKGROUND: No evidence of disease activity (NEDA) is a composite surrogate assessing the responsiveness to various disease-modifying treatments (DMTs) in patients with relapsing and remitting multiple sclerosis (RRMS), addressing clinical as well as radiological disease activity. Despite the rising prevalence of multiple sclerosis in Saudi Arabia (SA), there is a lack of evidence focusing on this important aspect in the management of RRMS. This study aimed to identify the prevalence of NEDA-3 status achievement in patients with RRMS on DMTs (mainly the interferon) and to describe the factors affecting its attainment. METHOD: This was a retrospective, cross-sectional study carried out at King Fahd University Hospital after obtaining institutional ethical approval. The electronic records of 119 patients diagnosed with RRMS were reviewed. Clinical manifestations at initial presentation, relapse after starting treatment, disability progression, and development of new lesions on follow-up magnetic resonance imaging were all documented to assess NEDA-3 status. Data were analyzed using Statistical Package for Social Sciences, version 22. RESULTS: NEDA-3 status was achieved in 41 (33.6%) patients. The female-to-male ratio for all patients was 1.5:1. Interferon (IFN) was the most commonly prescribed DMT. NEDA-3 status was achieved in 30.9% of patients receiving IFN. Mean baseline Expanded Disability Status Scale in patients who did not achieve NEDA-3 was 2.8±1.8. Patients with ataxia (P = <0.001), sphincter disturbances (P=0.002) and infra-tentorial brain lesions (P=0.03) were less likely to achieve NEDA-3 status. Involvement of pyramidal, cerebellar and more than one system at initial presentation was more frequent in patients who could not achieve NEDA-3 status (P=0.002) CONCLUSION: Less than one third of total patients on IFN as DMT could achieve NEDA-3 status in our cohort of patients which is in agreement with the literature published in the West. We could not properly asses NEDA-3 status for other DMTs in our center due to the very small sample size of patients on these DMTs, and recommend future studies including larger number of patients on DMTs other than IFN. Significant differences were identified between the two groups of patients with respect to attainment of NEDA-3 status, which requires further verification by multicenter prospective studies.

A Case Report of Intraparenchymal Neurocysticercosis in a Postpartum Female in Saudi Arabia.

Neurocysticercosis is a neurologic disease caused by infection with larvae of Taenia solium. It is most commonly transmitted by consumption of pork, water contaminated with T. solium or poor hygiene habits. As only few cases of neurocysticercosis have been documented in Saudi Arabia, the authors report a case of neurocysticercosis in a young Indian female residing in Saudi Arabia who presented with generalized tonic-clonic seizures 6 days after a normal vaginal delivery. Her physical and laboratory investigations as well as chest X-ray and electroencephalogram were all normal. Computed tomography of the head revealed multiple calcified nodular lesions, and magnetic resonance imaging showed ring-enhancing lesion in the left frontoparietal area. Serum enzyme-linked immunosorbent assay (qualitative) was positive for immunoglobulin G antibodies for cysticercosis. A diagnosis of neurocysticercosis was made, and the patient was treated with dexamethasone and levetiracetam for 4 days before discharge. At the 3-month follow-up, the patient's condition had significantly improved, and her seizures had not recurred. This report recommends considering neurocysticercosis as a differential diagnosis in patients presenting with new-onset seizures, even if the symptoms do not initially indicate neurocysticercosis or if the patient resides in an area where the disease is rare.

Tumefactive multiple sclerosis masquerade as a central nervous system tumor: a case report.

INTRODUCTION: Tumefactive multiple sclerosis is a demyelinating disorder that appears tumor-like on MRI. To most physicians, diagnosing tumefactive MS by applying clinical, radiological, or laboratory examination like Cerebrospinal fluid (CSF) analysis, can be challenging and ultimately biopsy is necessary to confirm the diagnosis. CASE PRESENTATION: This paper reports a case of a 37-year-old woman who presented with progressive headache and a strong family history of cancer and was misdiagnosed as having a CNS glioma. After considering the MRI features, CSF analysis results and observing improvement with IV steroids, the diagnosis of tumefactive MS was made. The patient refused biopsy to rule out the possibility of tumor or abscess. Nine months later, she presented with another relapse and an injectable disease modifying treatment (DMT) was initiated, and her course has been stable in follow up. TAKE-AWAY LESSON: The overall clinical importance of this case report is to highlight the real possibility of being forced to decide between Tumefactive demyelinating lesions (TDLs) and brain tumors in clinical practice, in order to avoid unnecessary biopsy.
