Patterns of multiple sclerosis presentation to the emergency department.

Background: Multiple sclerosis (MS) patients are no strangers to the emergency department (ED) due to the relapsing and progressive nature of the disease and the associated complications. This study aimed to identify patterns of ED visits among patients diagnosed with MS, the underlying causes of these visits, and the factors associated with these visits. Methods: This was a single center retrospective cohort study which utilized a non-probability consecutive sampling technique to include all patients diagnosed with MS (471 patients) from March 2016 to October 2021 in King Abdulaziz Medical City, Jeddah, Saudi Arabia. ED visits were categorized as directly related to MS, indirectly related to MS, or unrelated to MS. Results: One in four people with MS visited the ED at least once with a total of 280 ED visits. Most ED visits were ones directly related to MS 43.6%, closely followed by unrelated to MS 41.1%, and then indirectly-related MS visits 15.4%. The most common presenting symptoms in directly-related MS visits were weakness 56.6% and numbness/tingling 56.6% followed by gait impairment 29.5%. Indirectly related to MS or unrelated to MS ED visits were commonly due to neurological 17.7% and gastrointestinal 17.1% causes. Using disease modifying therapy (DMT) was significantly associated with no ED visits (p < 0.001). The use of high-efficacy DMTs was significantly associated with no ED visits than using moderate efficacy DMT (p < 0.001). The use of B-cell depleting therapy (ocrelizumab and rituximab) was significantly associated with no visits to the ED than using any other DMT (p < 0.001). Evidence of brain atrophy on imaging was significantly associated with patients who presented to the ED ≥3 times (p = 0.006, UOR = 3.92). Conclusion: Due to the nature of the disease, many MS patients find themselves visiting the ED due to MS related and unrelated issues. These patients are not only required to be treated by neurologists but also by multiple disciplines. The use of high-efficacy DMTs and B-cell depleting therapy may reduce the total frequency of ED visits. Special attention should be paid to patients who have evidence of brain atrophy on imaging.

The clinical and radiological features and prevalence of Neuro-Behçet's Disease: A retrospective cohort multicenter study in Saudi Arabia.

BACKGROUND: Neuro-Behçet's disease (NBD) is defined as primary neurological involvement in patients with systemic symptoms of BD. The variety of clinical presentations seen in NBD and the long list of similar conditions make diagnosis challenging. This retrospective study aimed to estimate the prevalence and describe neurological involvement in patients with Behçet's disease who presented to King Abdulaziz Medical Cities in Jeddah and Riyadh, Saudi Arabia. METHODS: This was a retrospective, cohort study which utilized a non-probability consecutive sampling technique to include all patients diagnosed with NBD patients. All patients with BD (215) were screened for neurological symptoms. Thirty-five patients were found to be diagnosed with NBD. Outcomes were estimated using the modified Rankin scale (mRS). RESULTS: In our cohort, one in six patients with BD was diagnosed with NBD. A total of 35 patients were diagnosed with NBD (mean age 27.56 ± 10.36 years; [2.88:1; Male: Female]). The main clinical features of NBD were headaches, weakness, unsteadiness, and dysarthria. The most commonly involved sites on imaging were the brainstem, diencephalon, cerebellum and basal ganglia. Oligocolonal bands were negative in all patients. Maintenance therapy most commonly included oral corticosteroids, azathioprine, and/or infliximab. Most patients received pulse corticosteroids alone when presenting with acute relapse. Half of our cohort was asymptomatic and three in four had favorable outcomes. CONCLUSION: NBD is common among patients with BD in our population with most patients having favorable outcomes. Patients might have a wide array of symptoms which might make the diagnosis challenging.

Incidence and Risk Factors of Spinal Anesthesia-Related Complications After an Elective Cesarean Section: A Retrospective Cohort Study.

Introduction Neuraxial anesthetic techniques are the method of choice for cesarean section (CS) deliveries, and spinal anesthesia (SA) is the preferred technique. Although the use of SA has greatly improved the outcomes of CS deliveries, SA-related complications are still a matter of concern. The study's primary aim is to measure the incidence of SA complications after a CS, specifically hypotension, bradycardia, and prolonged recovery, as well as to identify the risk factors for these complications. Method The data of patients who had elective CS using SA from January 2019 to December 2020 was collected from a tertiary hospital in Jeddah, Saudi Arabia. The study design was a retrospective cohort study. The data collected included age, BMI, gestational age, comorbidities, the SA drug and dosage used, the site of the spinal puncture, and the patient's position during the spinal block. Also, the patient's blood pressure measurements, heart rate, and oxygen saturation levels were collected at baseline and at 5, 10, 15, and 20 minutes. SPSS was used for statistical analysis. Results The incidence of mild, moderate, and severe hypotension was 31.4%, 23.9%, and 30.1%, respectively. In addition, 15.1% of the patients experienced bradycardia, with 37.4% experiencing a prolonged recovery. Two factors were associated with hypotension, including BMI and the dosage of the SA, with a p-value of 0.008 and a p-value of 0.009, respectively. The site of the SA punctures equal to or lower than L2 was the only factor associated with bradycardia (p-value = 0.043). Conclusion The present study concludes that BMI and the dose of SA were the factors associated with SA-induced hypotension during a CS, and the site of the SA puncture equal to or lower than L2 was the only risk factor associated with spinal anesthesia-induced bradycardia.

A Novel Mutation in the NAGLU (N-Acetyl-Alpha-Glucosaminidase) Gene Associated With Mucopolysaccharidosis Type III-B in a Saudi Girl.

Mucopolysaccharidosis type III-B (MPS III), also known as Sanfilippo syndrome, is a rare autosomal recessive lysosomal storage disease that primarily affects the brain and spinal cord. In this report, we describe the case of an eight-year-old female child who presented to the emergency room with an asthma exacerbation. She had coarse facial features, thick eyebrows, deep-seated eyes, thinning coarse hair, and macrocephaly. Moreover, she suffered from hepatosplenomegaly, generalized muscular atrophy, global developmental delay, and scoliosis. Urinary glycosaminoglycans (GAGs) were within normal limits. Full genetic testing confirmed the diagnosis of Sanfilippo syndrome type B with a deficiency of alpha-N-acetylglucosaminidase caused by a homozygous mutation c.889C>T, p.(Arg297*) in the NAGLU (N-acetyl-alpha-glucosaminidase) gene. Chromosomal microarray analysis (CMA) showed a copy number variant (CNV) within the 1q24 region. Thus far, CNVs similar in size and position have not been reported in the literature, making this a novel mutation.

Migraine Prevalence and Analysis of Dietary Habits in Relation to Headache in the Female Population: A Single-Center Study From Jeddah, Saudi Arabia.

Introduction Lifestyle-related factors including dietary intake can significantly increase the chances of developing migraine. Some components of food items are thought to induce the release of vasoactive substances leading to the dilation of blood vessels, which in turn results in migraine episodes. This research aimed to assess the prevalence of migraine and examine the relation of the headache to the dietary patterns of female students and employees of King Saud bin Abdulaziz University for Health Sciences (KSAU-HS) - Jeddah experiencing migraine attacks as well as to assess the relationship between the migraine attacks and the available dietary items served at the food outlets within the campus. Methods Two questionnaires were developed for this study. The first questionnaire was a short survey asking about the characteristics of headaches. This survey aimed to estimate the prevalence of migraine among female students and employees in KSAU-HS. Of the participants who filled the first questionnaire, those who met the International Classification of Headache Disorders (ICDH-III) criteria for migraine were given a second questionnaire to further understand the characteristics of their migraine headaches and to assess lifestyle and diet-related aggravating factors. Results The final sample size for the calculated prevalence was 410; 352 were students and 58 were faculty members. It has been found that 165 (40.24%) participants of the KSAU-HS female population met the criteria for migraine. Two (2.2%) reported an association between chocolate consumption and headaches and seven (7.8%) reported a significant association between caffeine and headaches. No specific association was perceived by the respondents between migraine attacks and the following food items: citrus fruits, pickles, cheese, and dairy products. Conclusion Our study revealed that the widespread trends for excessive consumption of coffee and caffeinated beverages at food outlets within the educational institution are occult triggers for headache attacks in a significant portion of students with migraine. The recent shift in dietary habits in our community for excessive consumption of coffee and other tyramine-rich food items has negative consequences on productivity and the economy. Our results can be conceivably extrapolated to reflect the effect of dietary habits on other streams of society, including companies, firms, schools, and workplaces that are driven by the new dietary trends.
