Association Between Lysine Reduction Therapies and Cognitive Outcomes in Patients With Pyridoxine-Dependent Epilepsy.

Background And Objectives: Pyridoxine-dependent epilepsy (PDE-ALDH7A1) is a developmental epileptic encephalopathy characterized by seizure improvement after pyridoxine supplementation. Adjunct lysine reduction therapies (LRTs) reduce the accumulation of putative neurotoxic metabolites with the goal to improve developmental outcomes. Our objective was to examine the association between treatment with LRTs and cognitive outcomes.

Epilepsy, neuropsychiatric phenotypes, neuroimaging findings, and genotype-neurophenotype correlation in 22q11.2 deletion syndrome.

Objective: To describe the epilepsy, neuropsychiatric manifestations, and neuroimaging findings in a group of patients with 22q11.2 DS, and to correlate the size of the deleted genetic material with the severity of the phenotype.

Methods: We retrospectively analyzed the medical records of 28 patients (21 pediatric patients and 7 adults) with a genetically confirmed diagnosis of 22q11.

Evaluation of adherence to pediatric status epilepticus management guidelines in Saudi Arabia.

Objective: To assess compliance with the 2017 Saudi pediatric status epilepticus management guidelines and to printout the main obstacle for adherence to the guidelines.

Methods: A cross sectional study conducted in September 2019, using electronic survey. The survey sent to all the Pediatric Emergency physicians practicing in Kingdom of Saudi Arabia (KSA) through emails and WhatsApp and the questionnaire based on clinical scenario written in English language.

Metabolic and genetic disorders mimicking cerebral palsy.

Cerebral palsy is a syndrome that encompasses a large group of childhood movement and posture disorders that result from a lesion occurring in the developing brain. The clinical presentation of many metabolic and genetic conditions, particularly in highly consanguineous populations, can mimic cerebral palsy particularly at early age. The aim of this review article is to identify the clinical features that should alert the physician to the possibility of disorders that resemble cerebral palsy, the clinical and neuroimaging red flags, and highlight some metabolic and genetic conditions which may present with spasticity, ataxia and dyskinesia.

Neurological expression of an inherited translocation of chromosomal 1 and 7.

An unbalanced translocation of chromosome 1 and 7 (t[1;7]) associated with neurological phenotype and brain malformation has rarely been reported. This clinical report describes 3 siblings with brain malformations and a 13.5 Mb duplication of 1q42.

Acute psychosis in children: do not miss immune-mediated causes.

New-onset psychosis in children represents a complex presenting symptom. Psychosis can be attributable to a combination of factors and etiologies, and all possible causes must be systematically examined. There is growing evidence that a proportion of psychosis/ psychiatric manifestations in children may be immunemediated, and physicians should consider this etiology in each presentation of first-episode psychosis.
