Mycoplasma pneumoniae-Triggered Guillain-Barré Syndrome in Children: Two Case Reports of Different ICU Presentations.

Guillain-Barré syndrome (GBS) is an acute immune-mediated polyneuropathy with diverse clinical presentations. Mycoplasma pneumoniae has been increasingly recognized as a potential trigger, particularly in pediatric cases. This case report presents two atypical cases of M.

Pattern and etiology of early childhood epilepsy: An Experience at a tertiary care University Center.

Objectives: To investigate seizure characteristics, types, and define the etiology of epilepsy in children aged ≤2 years using the 2017 ILAE classification.

Methods: A retrospective chart review was conducted at King Khalid University Hospital, King Saud University Medical City, Riyadh, Kingdom of Saudi Arabia for children below 2 years of age diagnosed with epilepsy, and on anti-seizure medications from January 2017 - December 2018. The collected data involved detailed information on the patients' seizure, electroclinical, neuroimaging, laboratory evaluations, and underlying etiology.

Amelioration of Levetiracetam-Induced Behavioral Side Effects by Pyridoxine. A Randomized Double Blind Controlled Study.

Background: Levetiracetam is a relatively new-generation antiseizure drug approved for the treatment of focal and generalized seizures. Despite its favorable side effect profile and minimal drug-drug interactions, neuropsychiatric side effects are reported in up to 13% of children. A few case series have suggested that supplementation of pyridoxine may mitigate these side effects, but controlled trials are lacking.

Phenotypic characterization of KCTD3-related developmental epileptic encephalopathy.

The association between KCTD3 gene and neurogenetic disorders has only been published recently. In this report, we describe the clinical phenotype associated with 2 pathogenic variants in KCTD3 gene. Seven individuals (including one set of monozygotic twin) from 4 consanguineous families presented with developmental epileptic encephalopathy, global developmental delay, central hypotonia, progressive peripheral hypertonia, and variable dysmorphic facial features.

Clinical genomics expands the morbid genome of intellectual disability and offers a high diagnostic yield.

Intellectual disability (ID) is a measurable phenotypic consequence of genetic and environmental factors. In this study, we prospectively assessed the diagnostic yield of genomic tools (molecular karyotyping, multi-gene panel and exome sequencing) in a cohort of 337 ID subjects as a first-tier test and compared it with a standard clinical evaluation performed in parallel. Standard clinical evaluation suggested a diagnosis in 16% of cases (54/337) but only 70% of these (38/54) were subsequently confirmed.
