Hemorrhagic fever with renal syndrome (HFRS) and reversible splenial lesion syndrome are both considered uncommon conditions relatively rare. Fever, hemorrhage, and acute kidney injury are the prevailing symptoms frequently observed in cases of HFRS. We describe a case of a middle-aged man who had been hospitalized with fever and acute neurological symptoms. His main symptom was recurrent dizziness. Cranial computed tomography (CT) did not reveal any obvious lesions, such as encephalorrhagia or infarctions. The splenium of corpus callosum showed hyperintensity on brain magnetic resonance imaging (MRI), which is in line with the characteristic radiographic observations of reversible splenial lesion syndrome (RESLES). Further analyses revealed that the patient's platelet counts had decreased to 7×10⁹/L while hemorrhagic fever antibodies were positive. Eventually, the patient was diagnosed with HFRS and exhibited clinical improvements after active treatment.

Objectives: To identify the dysregulated functional miRNAs, miRNA-16, miRNA-143, and miRNA-200 as potential biomarkers of cerebral aneurysms(CAs) to aid in diagnosis and prognosis.

Methods: This is a prospective case-control study conducted among patients with CA. All patients' computed tomography angiography (CTA) and interventional angiogram were assessed and studied. The miRNAs were isolated and quantified from peripheral blood samples and the expression profiling was done using TaqMan chemistry on Real-Time PCR.

Results: A total of 37 samples were included. Three cases had double aneurysms and 10 cases presented with aneurysmal rupture. miRNA-16, miRNA-143, and miRNA-200 were upregulated with an absolute fold-change of >8 in the CA group in comparison to controls (p<0.05). miRNA-200 showed double expression in patients with single aneurysm. A statically significant increase was observed in the expression of miRNA-143 in patients who had an aneurysmal rupture with p<0.05. Diabetic patients showed an obvious increase in miRNA-200 (13.03 folds) and miRNA-16 (26.82 folds) expression. Also, there was a notable elevation in miRNA-16, miRNA-143, and miRNA-200 in patients who had hypertension in comparison to those who did not.

Conclusion: miRNA-16, miRNA-143, and miRNA-200 showed statically significant higher expression among cases with cerebral aneurysms in comparison to controls. Thus, these preliminary results of miRNAs biomarkers are promising future tool to be used for aneurysmal screening.

Objectives: To compare the effectiveness of aspirin-clopidogrel dual antiplatelet therapy (DAPT) with aspirin or clopidogrel antiplatelet monotherapy (AM) in patients with ischemic stroke.

Methods: It was a single-center, retrospective cross-sectional study of medical records of ischemic stroke patients admitted at King Abdulaziz University Hospital between January 2015 and October 2019. The primary endpoints were ischemic stroke recurrence, rehospitalization, and all-cause mortality between DAPT and AM. Kaplan-Meier and Cox proportional hazard analyses were employed in univariate and multivariate time-to-event analyses.

Results: The median time to recurrence of ischemic stroke was 15.0 months (95% confidence interval [CI], 8.586-23.01) for DAPT and 20.4 months (95% CI, 9.872-30.928) for the AM. The median survival time until all-cause mortality was 8.0 months (95% CI, 2.893-13.107) for DAPT and 14.1 months (95% CI, 8.173-19.97) for the AM. No statistically significant reductions in the instantaneous risks of recurrence (hazard ratio [HR], 1.27; 95% CI, 0.59-2.72; p=0.54), re-hospitalization (HR, 0.95; 95% CI, 0.59-1.48; p= 0.77), and mortality (HR, 1.04; 95% CI, 0.48-2.26; p=0.92) were found between the DAPT and AM groups.

Conclusion: The DAPT was not superior to AM in reducing recurrence and mortality events in patients with ischemic stroke. Rehospitalization due to the sequelae of the composite of stroke, angina, and myocardial infarction was higher in the DAPT group.

Coronavirus disease 19 (COVID-19) is known to manifest itself predominantly with respiratory symptoms. However, previous experiences with this disease and many scientific studies have drawn attention to its neurological manifestations. The link between COVID-19 and many neurological diseases, including Guillain Barré syndrome (GBS), has been pointed out. Although GBS is considered a monophasic disease, its relapses occur in 2-6% of cases. We present the case of a female patient with recurrent GBS caused by COVID-19. Given that 2-6% of patients experience a relapse of GBS, and that the COVID-19 pandemic is recognized as a possible trigger of the relapse, we emphasize the importance of intensive neurological monitoring for patients diagnosed with COVID-19 who have a history of GBS.

Objectives: To assess the quality of life for epilepsy patients in Saudi Arabia. Epilepsy, one of the most prevalent chronic neurological conditions in the world, frequently results in a low quality of life.

Methods: This cross-sectional study analyzed data between September 2020 and September 2021 from 102 adult patients with epilepsy in outpatient clinics department of Epilepsy Program at King Fahad Medical City compared it to 108 healthy controls during the same study period. Sociodemographics and clinical data were gathered using the Arabic version of the Rand 36-Item Short Form Survey (SF-36) questionnaire and the Quality of Life in Epilepsy Inventory (QOLIE-31).

Results: Patients with epilepsy had lower SF-36 scores when compared to the control for role limitation due to physical health, role limitations due to emotional health, and general health. The QOLIE-31 revealed that gender was associated with energy/fatigue (p=0.028), medication effect (p=0.016), and social function (p=0.003); only social functioning showed a significant association (p=0.023) with employment.

Conclusion: Quality of life for patients with epilepsy was found to be significantly impacted in Saudi Arabia. Certain factors found in this study differentiate it from data that has already been released. This might be due to Arab differences in family support as well as cultural and religious beliefs.

Objectives: To study higher education student perceptions regarding the practice of telemental health services in Saudi Arabia.

Methods: The study conducted a cross-sectional descriptive design through an online self-administered survey. The targeted number of responses was set to at least 385 convenience-sample students who were enrolled in different degree programs at the selected university for the Spring 2022 semester. Data collection was done during March 2022.

Results: The sample population was 401 eligible responses. Most respondents Most respondents were from Riyadh (39.15%), females (66.33%), single (64.83%) at the time of data collection. Forty-five percent of participants did not use any telemental health services in the past. Moreover, 34.41% of the participants reported that they preferred to use mixed methods of mental services that combined face-to-face and distanced interactions. Telemental services that can be provided based on students' perceptions were consultations (75.81%), followed by education and promotion (64.33%). Almost half of the participants reported that the internet and culture are among the factors that have shaped their perceptions of telemental health in Saudi Arabia, while the least important factor was their experience with providers.

Conclusion: The current study showed that the higher education students perceived telemental health positively and were willing to use telemental health in the future; in addition, the most essential technologies related to telemental health services were videoconferences, audio-visuals, and telephones.
