We aimed to develop a registry ('Keto-Reg') for individuals with epilepsy referred for ketogenic dietary therapy (KDT) and to test feasibility of its implementation. The purpose of the registry is to provide a platform for collaborative research to answer specific research questions regarding long-term clinical and safety outcomes and to identify the most suitable candidates for KDT. Registry data items were determined via an international Delphi survey of KDT healthcare professionals, and then entered into an electronic platform.

Complete weaning from breastfeeding is not required to implement KDT; however, breastfeeding remains uncommon. Barriers include feasibility concerns and lack of referrals to expert centres.

Methods: Following a three-day baseline, patients (n = 19; age: 19 years [SD 13], range: 8-46 years) followed a KD for 28 days (control period), then incorporated ≥200 mL/day of a ready-to-use liquid feed, made with a ratio of 2.
Background: Many infancy-onset epilepsies have poor prognosis for seizure control and neurodevelopmental outcome. Ketogenic diets can improve seizures in children older than 2 years and adults who are unresponsive to antiseizure medicines. We aimed to establish the efficacy of a classic ketogenic diet at reducing seizure frequency compared with further antiseizure medicine in infants with drug-resistant epilepsy.

Case reports have also implicated specific variants in RNF213 with an early-onset form of moyamoya disease with full penetrance. We aimed to expand the phenotypic spectrum of monogenic RNF213-related disease and to evaluate genotype-phenotype correlations.

Knowledge of the pathophysiological mechanisms underlying associations of stretch-activated ion channels with human disease is limited. Here, we describe 17 unrelated individuals with severe early-onset developmental and epileptic encephalopathy (DEE), intellectual disability, and severe motor and cortical visual impairment associated with progressive neurodegenerative brain changes carrying ten distinct heterozygous variants of TMEM63B, encoding for a highly conserved stretch-activated ion channel.

There is a need to identify key messages that reassure carers and help to prevent inappropriate, anxiety-driven behaviors associated with "fever phobia.

We aimed to establish details of motor phenotype and current pharmacological management of a representative cohort across a network of UK tertiary centres.
Methods: Prospective multicentre review of specialist motor disorder clinics at nine UK centres, collecting data on clinical features and pharmacological management of children and young people (CYP) with CP over a single calendar month.
Perampanel is an adjunctive treatment for epilepsy that works through the direct inhibition of AMPA receptors. The same molecular mechanism has recently been shown for a fatty acid, decanoic acid, prescribed in the medium chain triglyceride ketogenic diet for the treatment of patients with drug-resistant epilepsy. Because each compound has been proposed to act through a distinct AMPA receptor binding site, we predicted that perampanel and decanoic acid would act synergistically against AMPA receptors and, consequently, seizures.

Children with unilateral cerebral palsy (UCP) have complex health, education and social care needs. Delayed gross motor milestones are the most common presenting feature, and much of the early management focuses on gross motor skills and lower limb management. In later childhood, adolescence and adulthood, upper limb function has significant impact on activity, participation and independence.

To date the only genetic epilepsy consistently associated with this phenotype is PCDH19, an X-linked disorder restricted to females, and males with mosaicism. The SMC1A gene, which encodes a structural component of the cohesin complex is also located on the X chromosome.

Well validated QoL instruments for epilepsy exist but focus on capturing common themes pertinent to children and families as a group instead of focusing on themes important to individual patients and their families/carers. In addition, it is common for numerous items on these inventories to be left incomplete or responded to with "not applicable" since many of the items are not suitable for children with disabilities and their families.

Background: Hyperthyroidism is rare in pre-school children. Untreated, it can have a profound effect on normal growth and development, particularly in the first 2 years of life. Although neurological manifestations of dysthyroid states are well known, specific expressive speech and language disorder as a presentation of hyperthyroidism is rarely documented.

Hypertension occurs in up to two-thirds of children with GBS but is rarely the main presenting feature. We describe a teenager who presented with tachycardia, dizziness, flushing, and significant hypertension as well as ascending limb weakness and sensory disturbance with areflexia.

For most patients the genetic cause of the biochemical defect remains unknown due to incomplete understanding of the complex I assembly process. Nonetheless, a plethora of pathogenic mutations have been described to date in the seven mitochondrial-encoded subunits of complex I as well as in 12 of the nuclear-encoded subunits and in six assembly factors.

Their etiology is complex and cannot simply be explained by pressure effects. Now that barbiturates are less frequently used, clinicians are likely to be less aware of the phenomenon of coma blister formation; however, newer drugs have also been associated with the occurrence of coma blisters.

No systematic comparisons of genetically proven cases with thyroid transcription factor-1 (TITF-1) and epsilon-sarcoglycan (SGCE) mutations have been performed to date. Three index patients and one index patients' daughter underwent genetic analysis of the TITF-1 and the SGCE gene.
