Review of the spectrum of tuberous sclerosis complex: The Saudi Arabian Experience.

OBJECTIVES: To determine the prevalence of tuberous sclerosis complex (TSC) in the paediatric Saudi population and to characterise the range of clinical symptoms, neurocutaneous findings, neuroimaging results, and complications of the disease. METHODS: A total of 61 genetically confirmed TSC patients from the National Guard Health Affairs (NGHA) in Saudi Arabia were the subject of this retrospective descriptive analysis. The data were presented using descriptive measures. RESULTS: The mean age at diagnosis was found to be 4.9 years. Subependymal nodules (86.9%), numerous cortical tubers and/or radial migration lines (63.9%), and hypomelanotic macules (63.9%) were the 3 most common significant criteria. The vast majority (86.9%) of those diagnosed had epilepsy, of which 50% were considered medically intractable. Nearly half of our subjects underwent genetic testing, which revealed that TSC2 predominated over TSC1. Symptoms of Tuberous Sclerosis Complex-Associated Neuropsychiatric Disorders (TAND) were present in 66.7% of TSC1 patients and 73.9% of TSC2 patients. CONCLUSION: The findings of this study demonstrate that the clinical spectrum of TSC among Saudi children is consistent with the body of existing literature. The TSC2 was more prevalent than TSC1. The most frequent signs were cutaneous and neurological. Monitoring TSC patients regularly is crucial to identify any issues as soon as possible.

Effectiveness of intra-thecal methotrexate in refractory Anti-N-methyl-d-aspartate receptor encephalitis.

BACKGROUND: Anti-N-methyl-d-aspartate "anti-NMDA" receptor encephalitis is one of the most common autoimmune encephalitis for which first- and second-line therapies have been recommended following international consensus. However, some refractory cases do not respond to the first- and second-line therapy and require further immune-modulatory therapies such as intra-thecal methotrexate. In this study, we reviewed six confirmed cases of refractory anti-NMDA receptor encephalitis from two tertiary centers in Saudi Arabia that required escalation of treatment and received a six-month course of intra-thecal methotrexate. The aim of this study was to evaluate the effectiveness of intra-thecal methotrexate as immunomodulatory therapy for refractory anti-NMDA receptor encephalitis. METHODS: We retrospectively evaluated six confirmed cases of refractory anti-NMDA receptor encephalitis who did not improve after first- and second-line therapy and received monthly intra-thecal methotrexate treatment course for six consecutive months. We reviewed patient demography, underlying etiologies, and compared their modified Rankin score prior to receiving intra-thecal methotrexate and six months after completing the treatment. RESULTS: Three of the six patients showed a marked response to intra-thecal methotrexate with a modified Rankin scale of 0-1 at 6-month follow-up. None of the patients experienced any side effects during or after intra-thecal methotrexate treatment, and no flareups were observed. CONCLUSION: Intra-thecal methotrexate may be a potentially effective and relatively safe escalation option for immunomodulatory therapy of refractory anti-NMDA receptor encephalitis. Future studies on intra-thecal methotrexate -specific treatment regimens may further support its utility, efficacy, and safety in treating refractory anti-NMDA receptor encephalitis.

Clinical Characteristics and Risk Factors of Neonatal Hypoxic-Ischaemic Encephalopathy and Its Associated Neurodevelopmental Outcomes During the First Two Years of Life: A Retrospective Study in Saudi Arabia.

Objective: This study aimed to determine the clinical characteristics and factors associated with neonatal hypoxic-ischaemic encephalopathy (HIE) and its neurodevelopmental outcomes. Methods: We conducted retrospective case-control research to investigate the clinical and labour-related risk factors for HIE. In addition, a single-centre cohort study was conducted on infants with HIE to describe their neurodevelopment from birth to 24 months. For this investigation, cases with a diagnosis of HIE who were born at King Abdullah Children's Specialist Hospital (KASCH), Riyadh, Saudi Arabia, between 2015 and 2019 were identified and matched with controls from the same facility (1:4). Each case's clinical information was extracted using electronic medical records. In addition, 24-month follow-up HIE cases were included in a cohort study to describe their neurodevelopmental outcomes. Results: The sample includes 60 infants diagnosed with HIE and 234 infants serving as controls, with a mean gestational age of 38.8 weeks (SD 1.6) and a predominance of males (56.4%). Around one-third of the HIE cases (36.6%) had moderate HIE (stage 2), whereas 35.1% of infants had severe HIE (stage 3), according to Sarnat staging. Compared to the control group, children with HIE were twice as likely to be born to mothers with maternal comorbidities and more likely to have prepartum and intrapartum complications. A 24-month follow-up of neurodevelopmental outcomes for HIE babies revealed that approximately 24% exhibited delays in gross motor skill development, 22% in fine motor skill development, 33% in language skill development, and 22% in social skill development. Conclusion: In the HIE group, maternal comorbidities and prepartum or intrapartum complications were more common. The severity grade of HIE can be used to predict neurodevelopmental consequences. Enhancing patient care and rehabilitation requires a minimum of 24 months of neurodevelopmental follow-up.

Pediatrics COVID-19 and neurological manifestations: Single tertiary centre experience.

IMPORTANCE: Coronavirus disease 2019 (COVID-19) is a severe acute respiratory syndrome that is caused by a novel coronavirus 2 (SARS-CoV-2). It originated in China late December 2019 and was declared a global pandemic on March 12, 2020. Most reports of COVID-19 cases either presented with neurological manifestations or complications involve adults. Only few cases were reported in pediatric patients. OBJECTIVE: To report COVID-19 pediatric cases with neurological manifestations and identify the wide spectrum of its manifestations. DESIGN SETTING AND PARTICIPANTS: This was a retrospective, observational case series. Data of pediatric patients infected by SARS-CoV-2 presenting with neurological manifestations at King Abdullah Specialized Children Hospital in King Abdulaziz Medical City in Riyadh were collected from May 23 to June 30, 2020. RESULTS: We encountered 5 COVID-19 cases with neurological manifestations. Three patients who were previously healthy had new-onset neurological symptoms. Symptoms and signs included encephalopathy, ataxia, headache, seizure, papilledema, ophthalmoplegia, hyporeflexia, and different clinical spectra, such as Miller Fisher syndrome, meningoencephalitis, and idiopathic intracranial hypertension. Other patients attending our center were incidentally found to be SARS-CoV-2-positive, which caused a delay in the investigations required to reach diagnosis. CONCLUSIONS AND RELEVANCE: Our cases highlight the wide clinical spectrum of neurological manifestations in COVID-19 patients. Given the paucity of information about pediatric COVID-19 cases with neurological symptoms, we here reported these cases to shed light on the association between SARS-CoV-2 and neurological presentation. Moreover, our study indicates that many investigations are being delayed and could affect diagnosis and treatment.

Patient's Desire and Preference for Provision of Information Toward Greater Involvement in Shared Care.

OBJECTIVES: To determine the perceptions of patients on whether they receive sufficient information about their medical problems, their preferences to obtain information, and factors that may influence their preferences. DESIGN AND SETTINGS: Cross-sectional, questionnaire-based study conducted in a primary health-care center affiliated with the National Guard Hospital, Riyadh, Saudi Arabia. PATIENTS AND METHODS: Patients attending the center between October and December 2010 were interviewed using a questionnaire developed to meet the objectives of the study. RESULTS: A total of 245 patients participated in the study. The mean (±standard deviation) age of the participants was 43 (±16) years. Reported cases of dyslipidemia, diabetes mellitus, and hypertension among participants were 42%, 39%, and 31%, respectively. A minority of the participants indicated that they had a sufficient knowledge of their medical problems. The vast majority of the patients (92%) indicated that their preference to be informed about available treatment options and the plan for their future treatment. However, only 38% indicated that they had been told about the available treatment options, and less than half (48%) were informed about their future treatment plan. The proportion of male patients who preferred to know the treatment plan for their medical problems was significantly more than that of females (P < 0.001); nevertheless, female participants perceived that they had been better informed about their treatment plan than the male participants (P = 0.003). CONCLUSION: This study demonstrates that patients receive information about their medical problems much less than their expectations. Measures to promote patient education and their involvement in shared care process should be considered and implemented to minimize serious health outcomes.

Shared clinical decision making. A Saudi Arabian perspective.

OBJECTIVES: To determine preferences of patients regarding their involvement in the clinical decision making process and the related factors in Saudi Arabia.   METHODS: This cross-sectional study was conducted in a major family practice center in King Abdulaziz Medical City, Riyadh, Saudi Arabia, between March and May 2012. Multivariate multinomial regression models were fitted to identify factors associated with patients preferences.  RESULTS: The study included 236 participants. The most preferred decision-making style was shared decision-making (57%), followed by paternalistic  (28%), and informed consumerism (14%). The preference for shared clinical decision making was significantly higher among male patients and those with higher level of education, whereas paternalism was significantly higher among older patients and those with chronic health conditions, and consumerism was significantly higher in younger age groups. In multivariate multinomial regression analysis, compared with the shared group, the consumerism group were more likely to be female [adjusted odds ratio  (AOR) =2.87, 95% confidence interval [CI] 1.31-6.27, p=0.008] and non-dyslipidemic (AOR=2.90, 95% CI: 1.03-8.09, p=0.04), and the paternalism group were more likely to be older (AOR=1.03, 95% CI: 1.01-1.05, p=0.04), and female (AOR=2.47, 95% CI: 1.32-4.06, p=0.008).  CONCLUSION: Preferences of patients for involvement in the clinical decision-making varied considerably. In our setting, underlying factors that influence these preferences identified in this study should be considered and tailored individually to achieve optimal treatment outcomes.
