Objective: Pathogenic variants in SCN8A have been associated with a wide spectrum of epilepsy phenotypes, ranging from benign familial infantile seizures (BFIS) to epileptic encephalopathies with variable severity. Furthermore, a few patients with intellectual disability (ID) or movement disorders without epilepsy have been reported. The vast majority of the published SCN8A patients suffer from severe developmental and epileptic encephalopathy (DEE).

Methods: We performed massive parallel sequencing of GABRB3 in 416 patients with a range of epileptic encephalopathies and childhood-onset epilepsies and recruited additional patients with epilepsy with GABRB3 mutations from other research and diagnostic programs.
Results: We identified 22 patients with heterozygous mutations in GABRB3, including 3 probands from multiplex families.
The first mutations identified in SLC2A1, encoding the glucose transporter type 1 (GLUT1) protein of the blood-brain barrier, were associated with severe epileptic encephalopathy. Recently, dominant SLC2A1 mutations were found in rare autosomal dominant families with various forms of epilepsy including early onset absence epilepsy (EOAE), myoclonic astatic epilepsy (MAE), and genetic generalized epilepsy (GGE). Our study aimed to investigate the possible role of SLC2A1 in various forms of epilepsy including MAE and absence epilepsy with early onset.

This paper aims to give attention to the syndrome through four case descriptions. Furthermore, possible risk factors and the use of the mutation 677C-T as a risk marker are discussed.

Materials And Methods: A questionnaire regarding visitation, admission, observation, discharge and follow-up of children with commotio cerebri as well as department guidelines was mailed to Danish paediatric departments in the period March-September 2006.
Results: Children are often initially treated in the emergency room and admitted to a paediatric department if there is a need for observation.
A list of practical advice and examples are given based on the literature. E-learning with cliffhanger text-cases can activate prior knowledge, and selected examination skills can be trained with simulated patients. Patient video recordings can be used to train clinical reasoning skills, including pattern recognition and hypothetic-deductive approaches.
