Randomized Controlled Trial Comparative Study Clinical TrialThe analgesic efficacy of diclofenac dispersible and ibuprofen in postoperative pain after dental extraction.
We have compared single oral doses of drinkable diclofenac dispersible (50 mg) with ibuprofen (400 mg) and placebo in a randomized, double-blind, parallel-group trial in 127 adults complaining of at least moderately severe pain after removal of an impacted third molar. Within 40 min both diclofenac and ibuprofen produced significant pain relief that persisted for 6 h. There were no differences between diclofenac and ibuprofen in analgesic efficacy.

Randomized Controlled Trial Clinical TrialMorphine-sparing effect of diclofenac in cancer pain.
The effectiveness of diclofenac 50 mg t.i.d. as additive treatment to parenteral patient-controlled administration therapy (PCAT) with morphine in cancer pain has been investigated in a double-blind study. In the fifteen patients who completed the study, morphine i.v. was titrated to optimal pain relief over 5 days. The mean total morphine consumption was significantly reduced during diclofenac administration (82.8 mg morphine per day) compared to placebo (95.0 mg morphine per day). ⋯ Pain, self-assessed according to VAS, tended to be lower during the diclofenac period, although the difference did not reach statistical significance. No adverse events were recorded among the 15 patients who completed the study. The present findings show that a non-steroidal anti-inflammatory agent, such as diclofenac, has a morphine-sparing effect in morphine-treated patients with cancer pain.

Since the withdrawal of phenformin in 1978, the use of metformin has increased from 13,500 to 22,000 patient years/year. During the period 1977-91 a total of 18 cases of metformin-associated acidosis was reported, of which 16 had lactic acidosis. ⋯ All the reports described patients with several other concomitant diseases, mainly cardiovascular and renal, when the acidosis was diagnosed. It is important continuously to re-evaluate metformin therapy and to stop treatment at the onset of impaired renal or cardiovascular function.

Randomized Controlled Trial Clinical TrialEffects of thiopentone/suxamethonium on intraocular pressure after pretreatment with alfentanil.
The effects of pretreatment with alfentanil on intraocular pressure (IOP) were investigated in 40 patients undergoing ophthalmic surgery. Patients were randomly allocated to two study groups. Group 1 patients (n = 20) received alfentanil 15 micrograms.kg-1, vecuronium 0.01 mg.kg-1, thiopentone 3-4 mg.kg-1, and suxamethonium 1 mg.kg-1 for anaesthetic induction, whereas patients in group 2 (n = 20) received vecuronium 0.01 mg.kg-1, thiopentone 3-4 mg.kg-1, and suxamethonium 1 mg.kg-1. ⋯ In group 2 patients, there was an increase in IOP after endotracheal intubation. In group 1 patients, a decrease in IOP occurred which was related to the decrease in arterial blood pressure. We conclude that alfentanil pretreatment can prevent the increase in IOP following suxamethonium administration.

Randomized Controlled Trial Comparative Study Clinical TrialEffect of penicillin on the clinical course of streptococcal pharyngitis in general practice.
The aim of the study was to explore whether penicillin was superior to placebo in altering the clinical course of proven streptococcal pharyngitis. A randomised, parallel, double blind placebo controlled trial of 10 days duration was undertaken in 42 general practices in the Gent region (Flemish part of Belgium). Phenoxymethylpenicillin (adults 250 mg t.i.d. and children 125 mg t.i.d.) or placebo were administrated to 173 patients, aged 5 to 50 y, with acute sore throat and a positive culture for Group A beta-haemolytic streptococci. ⋯ Penicillin had more adverse effects than placebo (P < 0.007). It also inhibited the rise in ASLO (P < 0.001). In this study in general practice, penicillin had a slight but definitive positive effect on the clinical evolution of streptococcal pharyngitis.(ABSTRACT TRUNCATED AT 250 WORDS)
