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 To report COVID-19 pediatric cases with neurological manifestations and identify the wide spectrum of its manifestations. 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. 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. 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.

Purpose: The aim of this manuscript was to assess the epidemiology and clinical features of Neurofibromatosis type 1 (NF-1) based on the newly published revised NF-1 diagnostic criteria and to evaluate complications of NF-1 including neurodevelopmental disorders. Patients and methods: A retrospective cross-sectional observational study was conducted in the Ministry of National Guard Health Affairs (MNGHA) healthcare organization branches including four tertiary hospitals and 51 primary health care centers in different regions in Saudi Arabia. This study included all patients diagnosed with NF1 using the revised NIH diagnostic criteria published in 2021 that were registered at the electronic medical records (EMR) from 2015 to 2021. Results: A total of 184 patients fulfilled the diagnostic criteria and were included in this study. The median age at diagnosis was 11 years (IQR: 4.00– 20.25). The most encountered diagnostic criteria in this study were Café-au-lait macules (85.3%), and (42.9%) were found to have two or more neurofibromas with plexiform neurofibroma being the most common subtype (23.36%), approximately (36.4%) of the patient with optic pathway glioma. Nearby (26.6%) of the patients displayed different type of tumors. Iris Lisch nodules were presented in 36.4% of patients at a median age of 12 years (IQR: 9.0– 21.8). Cardiovascular abnormality was encountered in 9.8% of the patients. Around 27.7% of the patients reported headache and 11.4% of the patient suffered from different type of epilepsy. Besides, 10.5% of the patients had intellectual disability, 33.8% suffered from communication disorders, and 4.9% patients had ADHD. Conclusion: The results of this study will enable practitioners to adopt a more holistic approach and prioritize numerous attributes, which they can subsequently incorporate into their therapeutic methodologies. Furthermore, the identification of these attributes will facilitate an expeditious and accurate diagnosis. Hence, the implementation of intervention during its nascent phase may result in a more advantageous consequence.

Biallelic pathogenic variants in mitochondrial aminoacyl-tRNA synthetase (mt-aaRS) PARS2 are associated with mitochondrial cytopathy. Here, we report the tenth case of an individual with biallelic PARS2 pathogenic variants, detected by exome sequencing (ES), and a literature review of ten cases of PARS2 mutations. Our patient displayed symptoms and clinical and laboratory findings similar to those reported previously with normal lactate levels. These symptoms included seizure disorder (which was managed with antiepileptics), developmental delay, and progressive cardiomyopathy which manifested at 19 years of age. The patient received a vitamin regimen including antioxidants as part of his treatment regimen. While further studies are required to conclusively establish the beneficial role of vitamin and cofactor administration on the mitochondria in PARS2-associated mitochondrial disease, these factors may have delayed the onset of cardiomyopathy.

The FAR1‐related phenotypes caused by the FAR1 gene encodes the peroxisomal protein fatty acyl‐CoA reductase 1 (FAR1), which is required to reduce fatty acids to fatty alcohols used to form ether‐linked alkyl bonds. Biallelic loss‐of‐function variants have been associated with severe psychomotor developmental delay, seizures, cataracts, growth retardation with microcephaly, and spasticity. However, heterozygous variants in FAR1 have been recently linked to a rare genetic disorder called cataracts, spastic paraparesis, and speech delay (CSPSD). Here, we present the first Middle Eastern patient with a de novo pathogenic heterozygous variant in FAR1 identified by exome sequencing (ES) analysis and a detailed overview of the reported clinical phenotypes and genotypes. Our patient represents the milder end of the clinical spectrum, with medication‐free seizures by the first year of life, proper speech and fine motor development, as well as an absence of other previously reported features such as learning difficulties, axial hypotonia, and joint contracture. In addition, she had developmental dysplasia of the hip (DDH) that failed medical management, as well as faltering growth. Our patient adds to the small number of patients recognized to date and expands the clinical spectrum to provide better clinical delineation, improve diagnosis, and develop precision medicine approaches for this disorder.

Seizures are a common clinical indication of central nervous system damage or abnormality in neonates. We aimed to identify the etiologies, clinical characteristics, and radiological features of neonatal seizures. This is a cross-sectional, retrospective, descriptive study using data obtained from the neonatal intensive care unit in King Abdulaziz Medical City (KAMC), a governmental, academic tertiary hospital in Riyadh, Saudi Arabia. The population of interest were neonates diagnosed with a neonatal seizure at KAMC between April 2015 and March 2019. A total of 61 patients with neonatal seizures were included in the study. The most common etiology was hypoxic-ischemic encephalopathy (43%). A total of 32 patients were full-term (52.5%). Around one-fifth of the study sample (21.3%) had a family history of neonatal seizures. Around 43.0% of the patients had epilepsy episodes. More than half of the patients (57.0%) were on one anti-seizure medication. Patients were followed up after 1 year, they had multiple comorbidities, including developmental delay, epilepsy, and cerebral palsy. Developmental delay was identified in 62.3% of the patients. A total of 19 patients have passed away (31%). Neonatal seizures are a common manifestation of neurologic disorders in neonates and are associated with high morbidity and mortality. Therefore, early identification of seizure etiology and proper management may help to improve the outcome.
