Randomized Controlled Trial Multicenter Study Clinical TrialIbuprofen plus caffeine in the treatment of tension-type headache.
The effectiveness of caffeine as an adjuvant to ibuprofen has been documented in investigations of acute pain. Our objectives were to assess this agent in the treatment of tension-type headache and to establish clinical trial methods capable of assessing this agent in comparison with various tension headache treatments. Stopwatch technology was used for measurement techniques. ⋯ Sensitive methods have been introduced to assess differences in analgesia among over-the-counter analgesic agents in relieving tension-type headache pain. A double-blind study with this method suggests that ibuprofen and caffeine administered together provides greater analgesic effectiveness than either component alone.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Comparison of remifentanil versus regional anaesthesia in children anaesthetised with isoflurane/nitrous oxide. International Remifentanil Paediatric Anaesthesia Study group.
We compared the efficacy and safety of a remifentanil (0.25 microg x kg(-1) x min(-1)-based balanced anaesthetic technique with a bupivacaine-based regional anaesthetic technique in an open label, multicentre study in 271 ASA physical status 1 or 2 children aged 1-12 years. Subjects requiring major intra-abdominal, urological or orthopaedic surgery were randomly allocated to receive either intravenous remifentanil (group R; n = 185) or epidural bupivacaine (group B; n = 86) with isoflurane/nitrous oxide for their anaesthesia. The majority of children in both groups (85% in group R, 78% in group B) showed no defined response to skin incision, and although the mean increase in systolic blood pressure (+11 mm Hg) was significantly greater in group R than in group B, this change did not represent a serious haemodynamic disturbance. ⋯ Adverse events, mainly nausea and/or vomiting, occurred in 45% of group R and 42% of group B (NS). The adverse event profile of remifentanil in this study was typical of a potent mu-opioid receptor agonist. Remifentanil was as effective as epidural or caudal block in providing analgesia and suppressing physiological responses to surgical stimuli in children aged between 1 and 12 years undergoing major abdominal, urological, or orthopaedic surgery under isoflurane/nitrous oxide anaesthesia.

Use of a simple pain model to evaluate analgesic activity of ibuprofen versus paracetamol.
To evaluate the analgesic activity of ibuprofen against paracetamol using a simple pain model. ⋯ Sore throat pain provided a sensitive model to assess the analgesic efficacy of class I analgesics and discriminated between the analgesic efficacy of ibuprofen and paracetamol.

Randomized Controlled Trial Multicenter Study Clinical Trial
A placebo-controlled trial of lamotrigine for painful HIV-associated neuropathy.
To investigate the analgesic efficacy of lamotrigine in the treatment of painful HIV-associated distal sensory polyneuropathy (DSP). ⋯ In this small trial, lamotrigine showed promise in the treatment of pain associated with HIV-related DSP. The frequency of rash was greater than in lamotrigine studies in epilepsy. A larger controlled study of lamotrigine is warranted.
