Randomized Controlled Trial Clinical TrialRecovery characteristics following anaesthesia with sevoflurane or propofol in adults undergoing out-patient surgery.
The aim of the study was to compare recovery characteristics in adult patients following general anaesthesia either with the new investigational volatile agent sevoflurane or with propofol. Accordingly, two groups of 25 adults undergoing outpatient surgery were entered into a prospective, randomised study. ⋯ Modified Aldrete scores were also higher in this group within the first hour after anaesthesia than in the propofol group. Sevoflurane appears to be a useful alternative to propofol in outpatient anaesthesia.

According to the World Health Organisation, a country's morphine consumption is an important indicator of progress in cancer pain relief. Due to its very high opioid consumption, Denmark is often pointed out as a country worthy of imitation. The aim of the present study was to analyse Danish opioid consumption in order to elucidate the usage pattern and to identify the consumers. ⋯ The consumption of long acting opioids (sustained release morphine, methadone, buprenorphine) and short acting opioids (others) increased by 1427% and 105%, respectively. Analysis of a sample of 1854 prescriptions for opioids revealed that less than 10% of the prescriptions were issued for cancer pain conditions. It is concluded: that if other countries consider Denmark as worthy of imitation in opioid treatment for cancer pain, attention should be paid to the pattern of the Danish opioid consumption, which is outstanding with respect to quantity but the quality may be questionable.

Randomized Controlled Trial Comparative Study Clinical TrialComparative efficacy of hamamelis distillate and hydrocortisone cream in atopic eczema.
In a double-blind, randomized, paired trial lasting 14 days in 72 patients with moderately severe atopic eczema, hamamelis distillate cream (5.35 g hamamelis distillate with 0.64 mg ketone/100 g) was compared with the corresponding drug-free vehicle and 0.5% hydrocortisone cream, and reductions of the basic criteria of severe atopic eczema (delta values of the sum scores), i.e. itching, erythema and scaling, were evaluated. Thirty-six patients in each group were treated, which allowed the detection of a 10% difference between verum and control (confirmatory study). Effects were compared using Wilcoxon's test. ⋯ Unwanted cutaneous reactions occurred in six patients, although due to their inflammatory nature and their confinement to vehicle-treated patients, they may not represent true adverse effects but rather a lack of efficacy. The results prove the superiority of low-dose hydrocortisone cream over hamamelis distillate cream, and the therapeutic outcome following this preparation was no better than following the base preparation. The mild, yet unmistakable anti-inflammatory effect of hamamelis cream in experimental models of inflammatory skin disease was thus not reflected by an efficacy in patients with atopic eczema greater than that obtained from the base preparation.

Randomized Controlled Trial Clinical TrialInfluence of piroxicam coadministration on pharmacodynamic parameters and the plasma concentration/effect relationship of recombinant hirudin (CGP 39393).
Recombinant hirudins are currently under investigation for use in myocardial infarction and unstable angina. In this study the influence of piroxicam on the pharmacodynamics and pharmacokinetics of a recombinant hirudin preparation (CGP 39393) administered intravenously was determined. Twelve healthy, male volunteers received piroxicam 10 mg and matching placebo once daily for 12 days according to a double-blind, randomised cross-over design. ⋯ No change was observed in the platelet adhesion index. Responsiveness parameters according to a sigmoidal Emax-model were obtained from the hirudin-plasma concentration/effect (i.e. APTT-prolongation)-curves after placebo and piroxicam.(ABSTRACT TRUNCATED AT 250 WORDS)

Case Reports4-methylpyrazole monitoring during haemodialysis of ethylene glycol intoxicated patients.
4-methylpyrazole (4-MP) was administered IV during haemodialysis of two ethylene glycol-intoxicated patients with anuric renal failure. The plasma 4-MP concentration decreased after each pass through the dialyser, indicating its dialysability in humans. In these two cases, the extraction coefficient was 0.78 and 0.71, and the mean dialysance was calculated to be 137 and 117 ml.min-1, corresponding to a 4-MP removal rate of 83 and 50 mg.h-1, respectively. ⋯ A recent study in pigs indicated that the amount of 4-MP removed by haemodialysis was significant [8]. No data were available for man. The aim of the study was to evaluate the dialysability of 4-MP in the two intoxicated patients, and to estimate how to compensate for 4-MP elimination during haemodialysis.
