The aim of this study was to analyze the prescription of high-potency (WHO step III) opioids with respect to regional differences and to assess the proportion of opioid-naïve new users of transdermal fentanyl. ⋯ Although oral morphine, oxycodone and hydromorphone are recommended as first-line step III opioids, transdermal fentanyl seems to be prescribed too often as the first choice and might not be appropriate.

Patients' readiness to behavioural changes according to the transtheoretical model (TTM) and criteria of treatment outcome are positively associated and have in part already been confirmed. For a stable effect of therapeutic treatment, patients' readiness to change seems indispensable for an independent and active pain management. Thus, in addition to an enhanced quality of life, increasing patients' motivation is a declared objective of the treatment at Dresden's Comprehensive Pain Center. In this study, it was examined how the readiness to change develops in the course of and during the 2 years following the multimodal treatment program. Furthermore, associations between outcome criteria of the treatment and patients' readiness to change were explored. ⋯ The results indicate that the outpatient pain management program favorably affects patients' motivation and general quality of life. This effect also seems to be stable over a long period of time. As not all patients show an improvement in stage of readiness to change, the question arises whether the reason of the differences might lie within the patients' and whether specific interventions for motivation might be useful to enhance motivation before starting treatment.

Parkinson's disease (PD) is caused by degeneration of the dopaminergic neurons in the substantia nigra (SN) and a resulting dysfunction of the nigrostriatal pathways including the basal ganglia. Beside motor symptoms, different types of pain (e.g., dystonic musculoskeletal pain or central pain) occur in a considerable number of patients. ⋯ The present article gives an overview of the relevant experimental studies, investigating the abnormalities of pain processing in PD by means of electrophysiological [electroencephalography (EEG), sympathetic skin response (SSR)] and psychophysical methods [quantitative sensory testing (QST), RIII reflex threshold]. Based on a review of the literature, it is postulated that dysfunction in endogenous pain inhibition caused by dopaminergic deficiency in the basal ganglia, especially in the striatum, but also in mesolimbic areas is a main pathophysiological mechanism involved in nociceptive abnormalities in PD.
