Randomized Controlled Trial Clinical Trial
The analgesic efficacy of topical capsaicin is enhanced by glyceryl trinitrate in painful osteoarthritis: a randomized, double blind, placebo controlled study.
The aim of this study was to assess if the pain of osteoarthritis is reduced by topical capsaicin and to determine whether addition of glyceryl trinitrate has an effect on analgesic efficacy and tolerability of capsaicin. A randomized, double blind, placebo controlled study was carried out on 200 adult patients attending a Pain Clinic with osteoarthritis pain. Patients applied one of four creams topically over the affected joint over a 6 week period. ⋯ The study showed that topical capsaicin and glyceryl trinitrate have an analgesic effect in painful osteoarthritis. When used together this effect is increased with the combination being more tolerable than capsaicin alone. Analgesic consumption is decreased by capsaicin, glyceryl trinitrate and to a greater extent by both combined.

Randomized Controlled Trial Comparative Study Clinical Trial
No effect of preoperative paracetamol and codeine suppositories for pain after termination of pregnancies in general anaesthesia.
Outpatient surgery demands rapid recovery and satisfied patients. The purpose of the study was to investigate whether rectal premedication with paracetamol and codeine would reduce the need of rescue analgesics, reduce the postoperative pain experience and result in faster eligibility for discharge. Ninety pregnant patients scheduled for day-case surgery with evacuation of the uterine cavity were randomly assigned into two groups. ⋯ The paracetamol and codeine patients were significantly more sleepy at 30 min postoperatively. There were no differences between the groups in postoperative nausea or vomiting and no difference in discharge eligibility. The use of pre-operative suppository with paracetamol 800 mg and codeine 60 mg is unnecessary in this group of patients.

Randomized Controlled Trial Clinical Trial
Citalopram in patients with fibromyalgia--a randomized, double-blind, placebo-controlled study.
The effect of the selective serotonin reuptake inhibitor citalopram was studied in a randomized, double-blind, placebo-controlled, 4-month trial in patients with the fibromyalgia syndrome (FMS) who all fulfilled the American College of Rheumatology criteria. The citalopram doses varied between 20-40 mg daily. Forty female patients, 21 patients in the citalopram and 19 in the placebo group, participated. ⋯ After 4 months, however, the effect had diminished. Measured with the FIQ, significant differences in the pain ratings were seen at the end of the trial. Significant effects on the depressive symptomatology measured by means of the MADRS were seen already after 1 month of treatment and were increasing further at the end of the trial, when a significant difference between the groups was also found.

Randomized Controlled Trial Multicenter Study Clinical Trial
Pain and quality of life in patients with critical limb ischaemia: results of a randomized controlled multicentre study on the effect of spinal cord stimulation. ESES study group.
We carried out an assessment of pain and quality of life of patients with critical limb ischaemia during the follow-up of a multicentre randomized trial in more detail than previously reported. In a multicentre clinical trial 120 patients were randomized between medical treatment and medical treatment plus spinal cord stimulation. Patients were selected on the basis of clinical symptoms and macrocirculatory data as described in the European consensus document on critical limb ischaemia. ⋯ Amputation had a negative effect on mobility, resulting in a difficult rehabilitation but relieved pain substantially (p<0. 05). In contrast to the existing literature, the randomized trial revealed no major difference in overall pain and quality of life assessment between treatment groups. The effect on energy and mobility was significantly better in patients treated with SCS, who also used substantially fewer analgesics.

Randomized Controlled Trial Comparative Study Clinical Trial
Plasma levels after peroral and topical ibuprofen and effects upon low pH-induced cutaneous and muscle pain.
Cutaneous applications are gaining popularity in the treatment of cutaneous pain and of painful disorders in joints and muscle. The low pH-pain model in human skin has previously been able to demonstrate the effects of NSAIDs in dose-dependent manner and to establish time-effect relationships. We examined the analgesic action of ibuprofen after cutaneous application and compared the effects with oral administration. ⋯ In the muscle model, the commercial ibuprofen gel did not reduce the pain in the acidic muscle. The peroral ibuprofen was less effective in the muscle compared to the skin pain model, although there was a significant progressive pain reduction within 55 min. Reasons for the differential susceptibility of cutaneous vs muscular acidosis pain to ibuprofen remain to be established.
