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 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.

Historical Article
Validation of the German version of the Fear-Avoidance Beliefs Questionnaire (FABQ).
Fearful avoidance of physical activities is a major factor in low back pain (LBP) and disability. In 1993 Waddell et al. developed the Fear-Avoidance Beliefs Questionnaire (FABQ) focusing on patients' beliefs about how physical activity and work affect LBP. The focus of our study was to analyse and validate the German version of the FABQ. ⋯ Patients out of work demonstrated more fear-avoidance beliefs in comparison to those who were still working. It can be concluded that the German version of the FAQB is a reliable and valid instrument, but it shows a different factor structure from the original English version. The FABQ has been proven to identify patients with maladaptive beliefs which have to be focused on in proper treatment.

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.

Tramadol is an option for the treatment of rheumatological pain. Its mode of action and safety profile distinguishes it from other opioids. Tramadol differs from other opioids by combining a weak opioid and a monoaminergic mode of action. ⋯ Tramadol should be avoided or used with caution in epileptics, or in individuals who are receiving seizure-threshold lowering drugs. Finally, tramadol has a low risk of abuse because it has only a weak opioid effect and its monoaminergic action could inhibit the development of dependence. The low abuse potential of tramadol has been demonstrated by postmarketing surveillance data.
