Prevalence of Medically Resistant Epilepsy in Saudi Arabia.

OBJECTIVES: The objective of this study was to evaluate the prevalence of medically resistant epilepsy (MRE) in our hospital and to compare the prevalence with that in other populations. METHODS: We retrospectively analyzed the data of patients who visited the epilepsy clinics at King Fahd University Hospital, Al-Khobar, Saudi Arabia between January 2017 and December 2018. This study included patients aged ≥14 years who had at least 2 unprovoked seizures 24 h apart. Patients who had provoked seizure(s), paroxysmal events, or syncope or had incomplete medical records were excluded. The definition and classification of the International League Against Epilepsy were used. Moreover, we searched the En-glish literature using PubMed and Google Scholar to compare the prevalence of MRE between our population and other populations. RESULTS: In total, 1,151 patients were screened, and 751 patients were included in the final analysis. Of the 751 patients, 229 (male: 56.3%, female: 43.7%; mean age: 32.07 years, and standard deviation, 12.2 years) had MRE, with a cumulative prevalence of 30%. The etiology was as follows: unknown, 63.3% (n = 145); structural, 31.9% (n = 73); genetic, 3.1% (n = 7); and infectious, 1.7% (n = 4). None of the patients had metabolic or immune-related etiologies. CONCLUSION: The prevalence of MRE in our population (30%) is close to that in other populations (30-36.5%). Early identification of such patients is crucial to improve their management.

Fat embolism in sickle-cell disease: A case report with literature review.

Background: Sickle cell disease (SCD) is associated with an under-recognized and well-known complication of bone marrow necrosis known as cerebral fat embolism (CFE). Case Presentation: We report a case of successfully treated SCD patient suffering from non-traumatic cerebral fat embolism (NCFE) who came with initial manifestation of localized pain followed by loss of consciousness and absence of cardiac shunt. This was an unusual case of fat embolism in SCD patient with the absence of right-to-left cardiac shunt indicating the biochemical etiology. Patient initially showed localized pain followed by loss of consciousness, suggesting that any such initial manifestation in patient of SCD should be suspected for CFE. MRI served as an accurate diagnostic tool showing the characteristic neuroradiologic sign. Treatment with exchange-transfusion recovered the patient successfully. Conclusion: Overall, this case suggested that prompt diagnosis using MRI and treatment with RBC exchange could lead to better outcomes in SCD patients suffering from CFE.

Important Factors to Expect the Outcome After Intracerebral Hemorrhage: An Observational Study From a University Hospital in Saudi Arabia.

BACKGROUND: Intracerebral hemorrhage (ICH) has worse clinical outcomes than other stroke types. The risk factors contributing to ICH outcomes are not entirely understood, and published literature from Saudi Arabia on ICH outcomes is limited. Our goal was to study the specific clinical and imaging determinants of ICH outcomes. METHODS: We retrospectively retrieved all patients with spontaneous ICH (SICH) from a prospective King Fahd Hospital University registry between 2017 and 2019. The clinical characteristics of ICH events and data on clinical outcomes (6 to 12 mo) were recorded. Groups of patients with a favorable modified Rankin Scale of 0 to 2 and nonfavorable outcomes of a modified Rankin Scale of 3 to 6 were investigated. The relationship between the clinical characteristics of the SICH event and its outcomes was assessed using linear and logistic regression analyses. RESULTS: A total of 148 patients with a mean age of 60.3 years (±15.2) and a median follow-up of 9 months were included. Unfavorable outcomes were reported in 98 patients (66.2%). The ICH event variables associated with unfavorable outcomes were impaired renal function, Glasgow Coma Score <8, hematoma volume, hematoma expansion, and intraventricular extension (IVE). CONCLUSIONS: Our study demonstrated important clinical and radiologic features in patients with ICH that may affect their clinical long-term functional outcomes. A larger multicenter study is required to validate our results and evaluate the methods to improve health care in patients with SICH.

Hypertensive Intracerebral Hemorrhage in Young Patients From a Tertiary Care Center in Saudi Arabia: An Observational Study.

Objective: Young patients with intracerebral hemorrhage (ICH) make up a small but important subgroup of patients with ICH. This study investigated the clinical characteristics and outcomes of hypertensive ICH in very young (18-45 years) and young (46-55 years) patients.Methods: This was a retrospective study of patients aged 18-55 years with hypertensive ICH admitted to a hospital from April 2014 to April 2019. Clinical and radiologic features as well as long-term clinical outcomes were compared between 2 age groups: group 1 (18-45 years) and group 2 (46-55 years). Factors affecting the clinical outcome were investigated as well.Results: Of 63 patients with hypertensive ICH, 24 (38.1%) were in group 1 (mean ± SD age of 38 ± 4.6 years), and 39 (61.9%) were in group 2 (50 ± 2.5 years). The risk factor profile was similar except for diabetes, which was more prevalent in group 1 (odds ratio [OR] = 4.65; 95% CI, 1.4-15.2). Patients in group 1 had higher mean ± SD NIH Stroke Scale scores (15.7 ± 4.6, P = .044), had lower Glasgow Coma Scale (GCS) scores (OR = 3.33; 95% CI, 1.0-10.8), were at higher risk of intubation (OR = 2.79; 95% CI, 1.1-9.9), and had higher ICH volume (21 ± 18, P = .034). Worse clinical outcome was higher in group 1 (OR = 5.14; 95% CI, 1.0-26.1). Low GCS score, mean hematoma volume, and intraventricular extension were independently associated with worse outcome.Conclusions: Relatively young patients with hypertensive ICH have higher prevalence of diabetes and worse clinical outcome in comparison to older patients with hypertensive ICH. Such patients should be monitored and treated more aggressively.
