The majority of patients with epilepsy have a good prognosis and their seizures are well controlled by a single antiepileptic drug, but up to 30% develop refractory epilepsy, especially those with partial seizures. In this review we summarise the current evidence regarding a new antiepileptic drug, gabapentin, when used as an add-on treatment for drug-resistant partial epilepsy. ⋯ Gabapentin has efficacy as an add-on treatment in patients with drug-resistant partial epilepsy. However, trials reviewed were of relatively short duration, and provide no evidence for the long term efficacy of gabapentin. Results cannot be extrapolated to monotherapy or patients with other epilepsy types.

ReviewAnti-epileptic drugs for preventing seizures following acute traumatic brain injury.
Seizure activity in the early post-traumatic period following head injury may cause secondary brain damage as a result of increased metabolic demands, raised intracranial pressure and excess neurotransmitter release. ⋯ Prophylactic anti-epileptics are effective in reducing early seizures, but there is no evidence that treatment with prophylactic anti-epileptics reduces the occurrence of late seizures, or has any effect on death and neurological disability. Insufficient evidence is available to establish the net benefit of prophylactic treatment at any time after injury.

The primary rationale for surgery for disc prolapse is to relieve nerve root irritation or compression due to herniated disc material. Claims of the merits of alternative surgical procedures are made without clear evidence about clinical outcomes. The objective of this review was to assess the effects of surgical interventions for the treatment of lumbar disc prolapse. ⋯ Chemonucleolysis is more effective than placebo and it is less invasive but less effective than surgical disectomy. Surgical discectomy for carefully selected patients with sciatica due to lumbar disc prolapse provides faster relief from the acute attack than conservative management, although any positive or negative effects on the lifetime natural history of the underlying disc disease are unclear.

ReviewSingle dose paracetamol (acetaminophen), with and without codeine, for postoperative pain.
Patient surveys have shown that postoperative pain is often not managed well, and there is a need to assess the efficacy and safety of commonly used analgesics as newer treatments become available. Paracetamol (acetaminophen) is an important non-opiate analgesic, commonly prescribed, as well as being available for retail sale. This review seeks to examine the efficacy of paracetamol alone and in combination with codeine, and also considers adverse effects. ⋯ Paracetamol is an effective analgesic with a low incidence of adverse effects. The addition of codeine 60 mg to paracetamol produces additional pain relief even in single oral doses, but may be accompanied by an increase in drowsiness and dizziness.

Review Comparative StudyMecamylamine (a nicotine antagonist) for smoking cessation.
Mecamylamine is a nicotine antagonist (that is it blocks the effect of nicotine). The rationale for its use in smoking cessation is that it may block the rewarding effect of nicotine and thus reduce the urge to smoke. ⋯ Data from two small studies suggest that the combination of nicotine and mecamylamine may be superior to nicotine alone in promoting smoking cessation. However, these results require confirmation in larger studies before the treatment can be recommended clinically.
