RESUMO

BACKGROUND: Multiple sclerosis (MS) is a chronic, inflammatory demyelinating disease that affects various parts of the central nervous system. Fatigue, a common symptom, transient, prolonged, or chronic experienced by individuals with MS, can significantly impact daily functioning. It can be associated with underlying pathological processes or can have an idiopathic cause, such as chronic fatigue syndrome (CFS). The study aimed to assess the presence and etiology of fatigue in MS patients and its relationship with CFS. MATERIALS AND METHODS: This cross-sectional study was conducted in the Eastern Province of Saudi Arabia. Data were collected using a questionnaire from a sample of 225 MS patients receiving care at our university hospital. The questionnaire included the Centers for Disease Control and Prevention (CDC) criteria for diagnosing CFS and the Expanded Disability Status Scale to evaluate fatigue in MS patients. RESULTS: Of the total of 225 MS patients who participated in this study, 87.1% were diagnosed with relapsing-remitting MS, 6.7% with primary progressive MS, 3.6% with clinically isolated syndrome, and 2.7% with secondary progressive MS. About 53% had experienced fatigue that persisted for over 6 months. Analysis of CFS diagnosis revealed that 7.3% of patients met both CDC criteria and self-reported answers while 17.5% reported having CFS despite not meeting the CDC criteria. These findings highlight a significant lack of agreement between patient-reported diagnoses and established criteria, indicating poor agreement (P = 0.028). CONCLUSION: The study found an association between CFS and MS, and a significant impact on daily functioning. The study revealed lack of agreement between patient-reported diagnoses and established criteria for CFS. This emphasizes the need for a standardized approach to diagnosis and evaluation of fatigue in MS patients.

RESUMO

Extramedullary hematopoiesis (EMH) is a rare cause of spinal cord compression (SCC) occurring in various hematological illnesses such as myeloproliferative disorders, thalassemias, and various types of anemia. EMH represents the growth of blood cells outside the bone marrow. Common EMH locations include the spleen, liver, lymph nodes, and paravertebral regions. When this occurs in the spinal cord, the mass effect can compress the spinal cord and cause different neurological symptoms depending on the area of the spinal cord affected. This report describes a 27-year-old female with a known case of beta-thalassemia major, who presented with mid-thoracic back pain, weakness, and paresthesia at the T10 level. In addition, this report illustrates the importance of considering EMH in the differential diagnosis of SCC in patients with thalassemia.

RESUMO

A sizable portion of the world's population suffers from migraines with aura. The purpose of this research is to describe the findings of a case-control study that was carried out to gain a better understanding of how migraine with aura manifests. The research looked at the P100 delay of the visual-evoked potential in both eyes of 92 healthy people and 44 patients who suffered from migraines with visual aura. All of the participants in the study were recruited from King Fahad University Hospital in Saudi Arabia. Both sets of people had the same ancestry and originated from the same location. Patients who suffered from migraines with aura exhibited a significantly shorter P100 delay in both eyes compared to healthy controls (p = 0.001), which is evidence that their early visual processing was distinct. In order to arrive at these findings, we compared people who suffer from migraines with aura to people who do not suffer from migraines and used them as subjects. These findings contribute to the ongoing attempts to bring the disease under control and provide vitally significant new information regarding the functioning of headaches with auras. The primary focus of study in the future should be on determining the nature of the connection between issues with early visual processing and headaches with aura.

RESUMO

BACKGROUND Cerebral amyloid angiopathy-related inflammation (CAA-ri) is an acknowledged syndrome of reversible encephalopathy, also known as cerebral ß-related angiitis. It is characterized by brisk progressive higher mental dysfunctions, headaches, seizures/epilepsy, and behavioral changes, and is highly responsive to immunosuppressive medications. To quickly and properly determine patients' management plans and prognoses, doctors are left with only CAA-ri-associated behavioral changes and seizures, in addition to a high index of suspicion of the correct diagnosis. CASE REPORT A 67-year-old woman was presented to the emergency room (ER) with behavioral changes and seizures. Upon screening, the patient was found to have radiological evidence of asymmetrical cortical-subcortical white-matter lesions accompanied by multiple cerebral microbleeds in the background of the negative screening for infectious/neoplastic and paraneoplastic processes. After undergoing a brain biopsy, the diagnosis was confirmed to be amyloid deposition within the inflammatory vessel walls. The patient showed a dramatic improvement after methylprednisolone pulse therapy, plasma exchange, and rituximab maintenance. CONCLUSIONS We encourage and support brain biopsies to confirm highly suspicious CAA-ri atypical cases to initiate early treatment and achieve the best outcome without any further delays.

RESUMO

OBJECTIVES: To describe the clinical features and possible etiologies of cerebral vein thrombosis (CVT) in a Saudi Arabian cohort. METHODS: A retrospective, observational design was implemented. Data pertaining to 36 patients (19 female and 17 male) with confirmed CVT diagnosis admitted to a hospital in Saudi Arabia between 2008 and 2019 were obtained and analyzed. RESULTS: The age of patients ranged between 19 to 82 years, and the mean/median age was 33/29 years. Most commonly reported symptoms were headache ( 72%), unilateral lower limb weakness (39%), and seizures (17%). Papilledema was found in 8% of patients. Thrombotic disorders were identified in 14% and infections were identified in 8% of the patients. Two patients had ulcerative colitis, 2 were diagnosed with Behcet's disease, and 2 women were using oral contraceptive pills. Single sinus thrombosis was detected in only 22% of patients. One patient with diabetic ketoacidosis died. Thrombotic disorder was the most common risk factor, followed by that iron deficiency anemia. CONCLUSION: The transverse sinus was the most frequently thrombosed sinus. Iron deficiency anemia emerged as a predisposing preventable condition for CVT, while genetic factors were found to be less important in this cohort.

RESUMO

BACKGROUND AND PURPOSE: Sex-related differences have been documented in risk factors distribution, etiologic subtypes, diagnostic evaluation, offered management, and outcome of patients with acute ischemic stroke (AIS) from all over the world. Nevertheless, studies from Saudi Arabia are lacking. This study aimed to investigate the influence of sex on distribution of risk factors and etiologic subtype of AIS in patients admitted to our hospital. MATERIALS AND METHODS: Record of patients admitted to King Fahd Hospital of the University between 2010 and 2017 with ischemic stroke (IS) were reviewed. Base line characteristics, risk factors, and etiologic subtypes according to Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification were compared between men and women. RESULTS: Among 453 patients with IS, 300 (66.2%) were men and 153 (33.7%) were women. The mean age of all patients was 61.5 ± 14.5 years. Women were older than men (P = 0.00). Hypertension (P = 0.00), atrial fibrillation (P = 0.00), and past history of stroke (P = 0.03) were more frequent in women compared to men. Fewer carotid Doppler studies (47.1 vs. 68.3%, P = 0.00) and echocardiogram (75.1 vs. 83%, P = 0.01) were done in women as compared to men. Cardioembolic etiologic subtype (26.1 vs. 17.7%) was found more frequently, whereas small vessel occlusive (23.5 vs. 31%) and large artery disease less (10.5 vs. 16.3%) frequently in women. CONCLUSION: Significant sex-related differences were found in risk factors and subtypes of AIS in our cohort of patients. Findings of our study are in general comparable with studies from all over the world.

RESUMO

We synthesized 10 analogs of benzimidazole-based thiosemicarbazide 1 (a-j) and 13 benzimidazole-based Schiff bases 2 (a-m), and characterized by various spectroscopic techniques and evaluated in vitro for acetylcholinesterase (AchE) and butyrylcholinesterase (BchE) inhibition activities. All the synthesized analogs showed varying degrees of acetylcholinesterase and butyrylcholinesterase inhibitory potentials in comparison to the standard drug (IC50 = 0.016 and 4.5 µM. Amongst these analogs 1 (a-j), compounds 1b, 1c, and 1g having IC50 values 1.30, 0.60, and 2.40 µM, respectively, showed good acetylcholinesterase inhibition when compared with the standard. These compounds also showed moderate butyrylcholinesterase inhibition having IC50 values of 2.40, 1.50, and 2.40 µM, respectively. The rest of the compounds of this series also showed moderate to weak inhibition. While amongst the second series of analogs 2 (a-m), compounds 2c, 2e, and 2h having IC50 values of 1.50, 0.60, and 0.90 µM, respectively, showed moderate acetylcholinesterase inhibition when compared to donepezil. Structure Aactivity Relation of both synthesized series has been carried out. The binding interactions between the synthesized analogs and the enzymes were identified through molecular docking simulations.

RESUMO

OBJECTIVES: To identify epilepsy triggers prevalent in Saudi Arabia with a view to seizure prevention or achieving a reduction in their frequency. METHODS: This is part of a cross-sectional study carried out in 2020 in a Saudi population in the Kingdom of Saudi Arabia (KSA). We used an online questionnaire to evaluate the most common seizure trigger factors. RESULTS: A total of 546 Saudi patients with epilepsy participated in the study, of which 289 (53%) were women. Of them, 263 (48.1%) had no seizure in the previous 3 months. One hundred and thirty-six (25%) had a family member with epilepsy. The most-reported trigger factor was sleep deprivation reported by 285 (52%), followed by stress 225 (41%), missed medication 210 (38.5%), anxiety 209 (38.3%), and fatigue 184 (33.7%). Conclusions: Sleep deprivation is the most reported trigger factor for seizures in the KSA, followed by stress, followed by missed medication.

RESUMO

OBJECTIVES: To determine relationship between fatigue, depression with the registration in multiple sclerosis (MS) society activity, and stress with the risk developing a new attack in patients with Relapsing remitting MS (RRMS) in the Kingdom of Saudi Arabia (KSA). METHODS: This was a cohort retrospective study conducted in the KSA between July 2018 and July 2019 which included a total of 465 RRMS patients. Data were collected during interviews using the Beck Depression Inventory (BDI) and Modified Fatigue Impacts Scale (MFIS). Demographic and clinical data were also collected. RESULTS: Of 465 participants, 317 expressed psychological stress before the last attack, 67 of whom developed an attack within 4 weeks, and 250 of whom developed an attack after 4 weeks. Significantly lower BDI scores were associated with registration in MS associations (p=0.003, df = 5). Significantly lower MFIS scores were associated with registration in MS associations (p=0.001, df = 5). CONCLUSION: The majority of RRMS patients have a significant fatigue and depression, and there are significant relationships between registration in the MS society and MFIS and BDI scores where patients who officially registered in MS society have lower score in MFIS and BDI. we recommend regular follow-ups with a psychologist and/or registration with MS societies.

RESUMO

OBJECTIVE: To assess the awareness of patients with multiple sclerosis about the relationship between smoking and multiple sclerosis in Saudi Arabia. METHODS: A descriptive cross-sectional study was carried out in 2018 for 162 patients who are attending a tertiary hospital in Jeddah, Kingdom of Saudi Arabia. Self-administered questionnaire and telephone-based interview were used to collect the data. The Analysis was carried out through a statistical package for the social sciences (SPSS) software version 21 by using chi-square. RESULTS: A total of 162 patients responded to the questionnaire (response rate, 58.1%). Among the respondents, 56 were current smokers, and 41 of them were males. Thirty-nine patients had a previous cessation attempt, and in 64.1% of the cases, it was mainly a self-made decision. Doctors counseled only 52.7% of the active smokers regarding the effect of smoking on the progression of their disease. CONCLUSION: Results indicate that there a is low level of awareness regarding the risk of smoking on multiple sclerosis. Therefore, educational programs and campaigns would be beneficial to fulfill the gap. Moreover, Health institutions and health care workers should take this issue into account when counseling the patient.

RESUMO

A new class of triazinoindole-bearing thiosemicarbazides (1-25) was synthesized and evaluated for α-glucosidase inhibitory potential. All synthesized analogs exhibited excellent inhibitory potential, with IC50 values ranging from 1.30 ± 0.01 to 35.80 ± 0.80 µM when compared to standard acarbose (an IC50 value of 38.60 ± 0.20 µM). Among the series, analogs 1 and 23 were found to be the most potent, with IC50 values of 1.30 ± 0.05 and 1.30 ± 0.01 µM, respectively. The structure-activity relationship (SAR) was mainly based upon bringing about different substituents on the phenyl rings. To confirm the binding interactions, a molecular docking study was performed.

RESUMO

OBJECTIVES: To determine if there is a relationship between acute stress and either the onset or relapse of multiple sclerosis (MS) and to discover how different types of acute stressors may be involved. Methods:  This study was carried out in Saudi Arabia between September 2017 and June 2018 and involved King Fahad University Hospital in Eastern province, Arfa Multiple Sclerosis Society in the Central and Western province of Saudi Arabia. A cross-sectional descriptive study was performed using an Arabic self-constructed questionnaire consisted of 4 sections: 1) demographic data and time of diagnosis; 2) emotional/psychological stressors; 3) environmental/physical stressors; and 4) 4 specific stressors measuring their effect on the severity and recurrence of attacks. Results: A total of 370 patients participated in the study. Almost half of patients reported no effect of family problems on their disease, whereas the other reported that family problems have an impact on the onset or relapse of the disease. Majority of patients reported that work and social life stressors affect the recurrence of attacks. Cold weather showed no effect on MS; however, hot weather and physical activity increased the number of attacks. Continuous thinking about social stress and problems, mood swings, and sleep deprivation showed an impact on the severity and recurrence of attacks. Financial problems showed no effect.  Conclusion: Study indicates that an association exists between acute stress and relapse in MS but not the disease onset.

RESUMO

OBJECTIVE: To assess the real-world tolerability of teriflunomide in multiple sclerosis (MS) patients from a large Canadian MS Centre of Care to determine whether previously treated (PT) patients have different tolerability thresholds than treatment-naive (TN) patients, leading to differing discontinuation rates. METHODS: This non-interventional, single-center, retrospective chart review examined all patients who were prescribed commercial teriflunomide between July 2014 and May 2015 at the MS Clinic in the Ottawa General Hospital and Research Institute, Ottawa, Canada. RESULTS: A total of 119 patient charts were reviewed (29 TN and 90 PT). Overall, 19 (15.9%) patients discontinued teriflunomide after a mean treatment duration of 35 weeks. The most common reason for discontinuation was side effects in 8 patients (42%).Discontinuation due to intolerability alone occurred in 13 patients. The number of discontinuations was not sufficient to demonstrate a statistically significant difference between TN and PT patients (p=0.1). CONCLUSION: This retrospective chart review provides some evidence about the real-world tolerability of teriflunomide. Discontinuations were low overall and consistent with previously reported clinical trial data. There was no significant difference in discontinuation rates between patients in the TN and PT groups. We believe that teriflunomide is a safe and well-tolerated oral alternative to injectable therapies.
