ReviewDrug management for acute tonic-clonic convulsions including convulsive status epilepticus in children.
Tonic-clonic (grand mal) convulsions and convulsive status epilepticus (currently defined as a grand mal convulsion lasting at least 30 minutes) are medical emergencies and demand urgent and appropriate anticonvulsant treatment. Diazepam, lorazepam, phenobarbitone, phenytoin and paraldehyde may all be regarded as drugs of first choice. ⋯ This review provides no evidence to suggest that intravenous lorazepam should be preferred to diazepam as the first-line drug in treating acute tonic-clonic convulsions including convulsive status epilepticus in children. There was some evidence from this review that rectal lorazepam may be more effective and safer than rectal diazepam, but the data were insufficient to indicate that lorazepam should replace diazepam as the first choice rectal drug in treating acute tonic-clonic convulsions and convulsive status epilepticus.

Review Meta AnalysisSedatives for opiate withdrawal in newborn infants.
Neonatal abstinence syndrome (NAS) due to opiate withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss and seizures. Treatments used to ameliorate symptoms and reduce morbidity include opiates, sedatives and non-pharmacological treatments. ⋯ In newborn infants with NAS, there is no evidence that phenobarbital, compared with supportive care alone, reduces treatment failure; however, phenobarbital may reduce the daily duration of supportive care needed. Phenobarbital, compared to diazepam, reduces treatment failure. There is insufficient evidence to support the use of chlorpromazine or clonidine in newborn infants with NAS. Clonidine and chlorpromazine should only be used in the context of a randomised clinical trial. The results of this review, taken in conjunction with the related review, Opiate treatment for opiate withdrawal in newborn infants (Osborn 2002), indicate that treatment with opiates is the preferred initial therapy for NAS. It is hypothesised that this is particularly true for infants whose mothers have used only opiates during pregnancy. If a sedative is used, phenobarbital is preferred to diazepam. The results of an ongoing trial of the addition of phenobarbital to an opiate are awaited.

ReviewCardioselective beta-blockers for chronic obstructive pulmonary disease.
Beta-blocker therapy has a proven mortality benefit in patients with hypertension, heart failure and coronary artery disease, as well as during the perioperative period. These drugs have traditionally been considered contraindicated in patients with chronic obstructive pulmonary disease (COPD). ⋯ The available evidence suggests that cardioselective beta-blockers, given to patients with COPD do not produce a significant short-term reduction in airway function or in the incidence of COPD exacerbations. However, the trials were small and of short duration. Given their demonstrated benefit in conditions such as heart failure, coronary artery disease and hypertension, cardioselective beta-blockers should be considered for patients with COPD, but administered with careful monitoring since data concerning long term administration and their effects during exacerbations are not available.

Epilepsy is a common neurological condition, affecting almost 0.5 to 1 per cent of the population. Nearly 30 per cent of people with epilepsy are resistant to currently available drugs. Tiagabine is one of the newer antiepileptic drugs and its effects as an adjunct (add-on) to standard drugs is assessed in this review. ⋯ Tiagabine reduces seizures frequency but is associated with some side effects when used as an add-on for people with drug-resistant localization related seizures.

ReviewCarbamazepine for schizophrenia and schizoaffective psychoses.
Many people with schizophrenia do not achieve a satisfactory treatment response with ordinary antipsychotic drug treatment and various additional medications are used to promote additional response. The antiepileptic carbamazepine is one such drug. ⋯ Based on currently available evidence from randomised trials, carbamazepine cannot be recommend for routine clinical use for sole treatment, or augmentation of antipsychotic treatment, of schizophrenia. Large, simple well-designed and reported trials are justified especially if focusing on those with violent episodes and people with schizoaffective disorders or on those with both schizophrenia and EEG abnormalities.
