Febrile seizures.

BACKGROUND: Febrile convulsions, or febrile seizures, are frequently encountered in paediatrics, and despite often being self limiting, these seizures strike fear in the hearts of patients' carers. OBJECTIVE: This article reviews the assessment and management of febrile seizures in children. DISCUSSION: The initial assessment of a child who convulses with fever should be directed at finding a cause for the fever, rather than the seizure itself, once the seizure has abated. A lumbar puncture should be performed if there is clinical suspicion of meningitis. Electroencephalograms and neuroimaging studies are not routinely indicated. Overall, febrile seizures carry a good prognosis, although one-third of children have recurrent attacks. Febrile seizures are genetic in origin. The risk of later epilepsy is small but increased if the child has a complex febrile seizure, neurological deficit, or a family history of epilepsy. Carers should be counselled in the management of seizures. The effectiveness of prophylactic treatment with medication remains controversial.

Should a lower treatment line be used when treating paracetamol poisoning in patients with chronic alcoholism?: a case for.

A lower threshold for treatment of paracetamol (acetaminophen) poisoning has been advocated in chronic heavy users of alcohol, based originally on animal studies indicating that chronic alcohol ingestion increased hepatotoxicity. This was attributed to increased production of the toxic metabolite, N-acetyl-p-benzoquinoneimine, by cytochrome P450 (CYP)2E1 induction. The clinical evidence for increased risk is limited to four retrospective studies with potential for referral and reporting bias and conflicting results. No study has specifically addressed the issue of the treatment threshold for acute paracetamol overdose in chronic alcohol users. However, animal studies in multiple species have consistently shown a lower dose of paracetamol is required to produce hepatotoxicity after chronic alcohol use. The knowledge of potential mechanisms has expanded to include effects of other alcohols, such as isopentanol, induction of CYP enzymes other than CYP2E1 and glutathione depletion. There are no convincing reasons or data to suggest these findings do not apply to humans. However, further human toxicokinetic and clinical research is required to quantify the extent of the interaction. Arguments about treating overdoses should not be confused with those about whether there is an alcohol-paracetamol interaction at therapeutic doses. Halving the threshold dose/concentration for treatment is a conservative educated guess that has been widely adopted. In overdose, the potential benefits of treatment at this lower threshold clearly outweigh the minimal risks of acetylcysteine.
