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.

Stroke literacy in the population of the Eastern Province of Saudi Arabia; immediate steps are essential to bridge the gap.

BACKGROUND AND PURPOSE: Stroke is a medical emergency that demands early recognition for time sensitive acute management. Knowledge about stroke in public has not been found satisfactory in most of the studies worldwide. Studies describing the awareness of public about recognition of stroke and its treatment from Saudi Arabia (SA) are deficient. This study aimed to assess the knowledge of general population living in the Eastern Province of SA about stroke in relation to recognition of warning signs, risk factors and available acute treatment. METHODS: A prospective, cross sectional study was conducted using a structured questionnaire distributed through an electronic web site over a period of six months. The data was analyzed with SPSS version 22.0. RESULTS: Among a total of 1,213 respondents, 62.4% were women. Three fourth identified the affected organ correctly. Psychological stress was the most commonly identified risk factor (73.5%) followed by hypertension (63.8%). More than half of the respondents (58.5%) were not aware of diabetes mellitus as a risk factor for stroke. Speech difficulty was the most commonly identified stroke warning sign (64.4%) followed by focal weakness (62.4%). More than half (59.9%) did not recognize facial asymmetry as stroke warning sign. Nearly three fourth of the participants were unaware of t-PA (73.7%) and nearest available health care center for acute stroke management (74.9%). CONCLUSION: Our survey found the stroke literacy in the population of the Eastern Province of SA as non- satisfactory and highlights the importance of taking immediate measure such as mass media campaign and hospital based activities to improve it.

Nonadherence to Antiepileptic Medications: Still a Major Issue to be Addressed in the Management of Epilepsy.

CONTEXT: Medication nonadherence is a significant barrier in achieving seizure freedom in patients with epilepsy. There is a deficiency of data about the reasons for nonadherence in Saudi population. AIMS: The aim of this study is to prove the existence of nonadherence to antiepileptic drugs (AEDs) in patients with epilepsy and identify the responsible factors. SETTING AND DESIGN: This is a prospective, cross-sectional study carried in the Department of Neurology at King Fahd Hospital of the University affiliated with Imam Abdulrahman Bin Faisal University. SUBJECTS AND METHODS: Patients of all ages diagnosed to have epilepsy as mentioned in their medical record and taking antiepileptic medications were interviewed using a questionnaire. STATISTICAL ANALYSIS USED: Statistical analysis was performed using IBM Statistical Package for the Social Sciences version 21 (IBM Corp., Armonk, NY, USA). Statistical significance was defined as two-tailed with a P ≤ 0.05. RESULTS: Among 152 participants, 52.6% were male and 47.4% were female. Mean age of the patients was 28 ± 14.3 (mean ± standard deviation) years. Of 152 patients, 48.7% were found to be nonadherent to their AED therapy. The most commonly identified factor was forgetfulness. Nonadherence was significantly associated with poor seizure control (P = 0.002). CONCLUSION: Nonadherence to the AED is common among patients with epilepsy and affects seizure control adversely.

Risk factors and subtypes of acute ischemic stroke. A study at King Fahd Hospital of the University.

OBJECTIVE: To identify the different subtypes of acute ischemic stroke, and estimate the frequency of various risk factors among these patients. METHODS: In this retrospective, cross-sectional study, we reviewed the medical records of patients admitted with the diagnosis of acute ischemic stroke at King Fahd Hospital of the University, Al-Khobar, Saudi Arabia from March 2008 till December 2015. The demographic characteristics, subtypes of stroke, risk factors (hypertension, diabetes mellitus, hyperlipidemia, coronary artery disease, atrial fibrillation, valvular heart disease) and other relevant data were documented on pre-defined data sheets. RESULTS: The records of 343 patients were included in the study; 64.4% were male and 35.6% were female. The mean age was 59.3+/-13.6 (mean+/-SD) years for males, and 66.8+/-14.9 years for females. Small vessel occlusion was the most common etiologic subtype of ischemic stroke (32.1%), followed by cardio embolic (21.9%), and large artery atherosclerosis (14.6%). The middle cerebral artery was the most commonly affected territory. Hypertension was found in 78.1%, diabetes mellitus in 62.7%, hyperlipidemia in 54.8%, and ischemic heart disease in 24.2% of patients. CONCLUSION: Small vessel occlusion was the most common etiology in our cohort. The onset of stroke at a relatively younger age group in the male population is of great concern and needs to be verified by further epidemiological studies. Adequate control of modifiable risk factors may help in reducing the disease burden caused by stroke.
