Randomized Controlled Trial Clinical TrialEffect of epidural buprenorphine and clonidine on vesical functions in women.
Buprenorphine (4 micrograms/kg body weight) and clonidine (3 micrograms/kg body weight) were administered epidurally to investigate their effect on vesical function in 20 American Society of Anaesthesiologists Classification I (ASA I) adult females. Cystometry was performed before and 30 minutes following epidural administration of drugs. ⋯ Epidural administration of clonidine did not produce any significant change in the above urodynamic parameters. None of the patients in both groups developed retention of urine.

Clinical TrialEvaluation of the therapeutic range of whole blood cyclosporin concentration in the treatment of psoriasis.
Cyclosporin (CyA) trough levels in whole blood in 17 patients receiving CyA for the treatment of severe psoriasis were measured by fluorescence polarization immunoassay (FPIA) employing a specific monoclonal antibody. Clinical success was defined as a PASI score reduction greater than or equal to 75% (group A), partial success by a PASI score reduction of 60%-74% (group B), and insufficient efficacy by a PASI score reduction of less than 60% (group C). Nine of the 17 patients given CyA (53%) exhibited an improvement rate of > or = 75% in the PASI score within 8 weeks of the initiation of treatment. ⋯ In these 2 patients the relapse may have been due, in part, to the sharp decrease in whole blood concentration secondary to partial noncompliance. Measurement of whole blood CyA trough level is the only method for assessing the patient's noncompliance. Contrary to previous reports we confirmed that the measurement of CyA concentration in whole blood was useful for monitoring the effects in patients with psoriasis.

Randomized Controlled Trial Clinical TrialA new route, jet-injection for anesthetic induction in children - II. ketamine dose-range finding studies.
Ketamine (K) i.m. has been widely used for anesthetic induction in small children in the last decades, if mask induction has failed. In many instances, however, physical restraint was required. In order to eliminate the pain of i.m. injection and to prevent the psychological and physical trauma associated with restraint, we evaluated the utility of jet-injection (j.i.) of K for anesthetic induction in a dose-range finding study. ⋯ None of the children experienced unpleasant recall or pain for the injection or the whole procedure. This new route of anesthetic induction with the jet-injector utilizing K may provide pain-free and stress-free induction as compared to its i.m. injection. This technique also prevents transmission of infection and is [correction of and cost] cost effective since simultaneous and/or sequential injection can be given from a single vial of K.

Randomized Controlled Trial Clinical TrialRelative bioavailability of controlled-release oral morphine sulfate during naltrexone blockade.
The effect of naltrexone hydrochloride on the bioavailability of 60 mg controlled-release oral morphine sulfate in normal volunteers was determined using a randomized, 2-way crossover, analytically blinded study design. Although naltrexone did not qualitatively alter the concentration-time curve for controlled-release morphine, the area under the plasma morphine concentration-time curve from 0-24 h (AUC0-24) was significantly greater (p < 0.01) for morphine given with naltrexone (265 ng x h/ml) than for morphine given alone (215 ng x h/ml). Compared to morphine given alone, the apparent absorption half-life of morphine was decreased from 0.94-0.58 h (p = 0.01) and Cmax was increased from 28.17 ng/ml to 32.26 ng/ml (p = 0.04) during naltrexone blockade, whereas the Tmax and apparent elimination half-life of morphine were not significantly affected. The minimal differences in morphine bioavailability indicate naltrexone may be useful in comparative bioavailability studies of high-dose opioids in opioid-naive normal volunteers.

Randomized Controlled Trial Comparative Study Clinical TrialComparative efficacy of diclofenac dispersible 50 mg and ibuprofen 400 mg in patients with primary dysmenorrhea. A randomized, double-blind, within-patient, placebo-controlled study.
Sixty female out-patients suffering from moderate to severe primary dysmenorrhea, aged 14-40 years (mean 27 years), entered this randomized, double-blind, 3-period, within-patient study, evaluating the efficacy and tolerability of diclofenac dispersible 46.5 mg (equivalent to 50 mg of diclofenac sodium), ibuprofen 400 mg and placebo taken up to 4 times daily for a maximum of 3 days. Pain relief was evaluated on a verbal rating scale (0 = none, 1 = slight, 2 = moderate, 3 = considerable, 4 = complete) at 0.5, 1,2,3,4,5 and 6 hours after the first dose; the weighted sum of pain relief scores over the 6-hour observation period was also investigated (TOTPAR-6). Pain intensity was assessed on a verbal rating scale (0 = nil, 1 = mild, 2 = moderate, 3 = severe) at baseline and at the above mentioned time points; the weighted sum of pain intensity differences at each time point was also analyzed (SPID-6). ⋯ Finally, adverse experiences were recorded throughout the study period. Analysis of covariance and Koch's adaptation of the Wilcoxon-Mann-Whitney rank sum test were used, where appropriate, for statistical analysis. Mean TOTPAR-6 values for diclofenac dispersible, ibuprofen and placebo were 16.5, 17.8 and 14.7, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
