Children presenting with convulsions (including status epilepticus) to a paediatric accident and emergency department: an audit of a treatment protocol.
All children who presented in a convulsion, including convulsive status epilepticus, to the accident and emergency department over a 12-month period and who required treatment, were reviewed retrospectively to identify the effectiveness and safety of a specific treatment protocol. This protocol recommends the initial use of one, or if necessary, two doses of rectal or intravenous diazepam (0.4 mg/kg) followed by the simultaneous administration of phenytoin (18 mg/kg) and rectal paraldehyde (0.4 mL/kg), with instructions for maximum doses and timings of administration. Eighty-one evaluable children (52 male) were audited. ⋯ Nine patients (11%) required admission to the intensive-care unit, five because of persisting convulsive activity, and four because of respiratory depression. The results of this retrospective audit suggest that the current treatment protocol appears to be effective and relatively safe in treating acute convulsions, including convulsive status epilepticus. The audit is to be repeated prospectively to either confirm or refute these findings before recommending any changes to the protocol.

Comparative Study Clinical Trial Controlled Clinical TrialLorazepam versus diazepam in the acute treatment of epileptic seizures and status epilepticus.
Lorazepam was compared with diazepam for the treatment of acute convulsions and status epilepticus in 102 children in a prospective, open, 'odd and even dates' trial. Convulsions were controlled in 76 per cent of patients treated with a single dose of lorazepam and 51 per cent of patients treated with a single dose of diazepam. ⋯ No patient who received lorazepam required admission to the intensive care unit for either respiratory depression or persisting status epilepticus. Rectally administered lorazepam appeared to be particularly valuable (100 per cent efficacy) when venous access was not possible.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA multicentre comparative trial of sodium valproate and carbamazepine in paediatric epilepsy. The Paediatric EPITEG Collaborative Group.
The long-term efficacy and adverse-event profiles of sodium valproate and carbamazepine in children with newly diagnosed primary generalised or partial epilepsy were compared at 63 outpatient clinics. Children with two or more generalised tonic-clonic or partial seizures in the previous six months were randomised to oral sodium valproate (N = 130) or oral carbamazepine (N = 130) and followed for three years as outpatients. ⋯ Adverse events were mostly mild, few necessitating drug withdrawal. Those particularly associated with valproate were weight increase, alopecia and appetite increase, and with carbamazepine, rashes, somnolence, diplopia and abnormal gait/ataxia.

Case ReportsSelective injury of the globus pallidus in children with post-cardiac surgery choreic syndrome.
Occasionally children undergoing cardiac surgery using cardiopulmonary bypass with deep hypothermia and cardiac arrest develop a postoperative syndrome of acute chorea. The authors report the neuropathological findings in two such children surgically treated for congenital heart disease. Examination of the brain showed neuronal loss, reactive astrocytosis and degeneration of myelinated fibers (without frank necrosis) in the globus pallidus, primarily the outer segment, with sparing of other regions commonly susceptible to hypoxic-ischemic necrosis. The localization and relative mildness of the brain damage suggest a susceptibility of the globus pallidus to injury in this setting and implicate disruption of pallidal pathways in the pathogenesis of post-cardiac surgery choreic syndrome.
