Use of the American College of Rheumatology classification criteria for the clinical diagnosis of fibromyalgia syndrome (FMS) is under debate. The Regional Pain Scale (RPS) had been developed for the diagnosis of FMS in clinical practice and in survey settings (survey criteria of FMS). So far a German version has not been validated. ⋯ The RPS has good reliability and convergent validity, but limited discriminant validity. The RPS is suited as a screening instrument for the diagnosis of FMS in clinical practice.

Pain perception is a central aspect of the multidimensional model of chronic pain. Up to now, validated measurement tools are lacking in the German language for measuring pain perception in adolescents. The aim of this study was to examine and adapt the well-established Pain Perception Scale for Adults by Geissner (SES) for use in adolescents with chronic pain to provide a measure for clinical diagnosis and evaluation of treatment effects. ⋯ With this questionnaire there is now a validated German assessment tool to measure pain perception in adolescents with chronic pain (Pain Perception Scale for Adolescents, SES-J). Due to its practicability it is suitable for clinical application.

The efficacy of opioids has been proved and several guidelines and expert panel-based recommendations regarding the use of opioids in different pain syndromes are available. Nevertheless, undertreatment of pain with strong opioids was reported in previous studies. It was shown that physicians' lack of knowledge, their concerns and misconceptions about the opioid use and the controlled substances regulations that govern the prescriptions of opioids occasionally contribute to insufficient pain treatment. This study was designed to evaluate German physicians' knowledge and their concerns about the use of opioids. ⋯ It is necessary to improve the medical students' education and the physicians' postgraduate training regarding principles of pain management such as the WHO guidelines for the treatment of cancer pain. A better knowledge of important pharmacological aspects of opioids should help to reduce physicians' concerns about the use of strong opioids. Nevertheless, improvement of physicians' skills in pain therapy is only one aim in a multidisciplinary concept in order to improve patients' pain therapy.

In 2009, the German version of ICD-10 (ICD-10 GM version 2009) introduced the diagnosis of "chronic pain disorder with somatic and psychological factors", because current ICD-10 diagnoses did not address the biopsychosocial character of chronic pain adequately. For most patients, a dichotomous classification into psychologically versus biomedically caused pain is inappropriate and does not reflect current knowledge on pain. The new code F45.41 addresses the relevance of psychological factors for chronic pain persistence and chronic pain treatment, even in those conditions with a clear biomedical cause at the beginning. ⋯ The distinction of this new diagnosis from other pain-associated diagnoses and recommendations for the coding of comorbid conditions are presented. The differentiation of everyday pain symptoms from pain disorders is outlined. Finally, contextual factors of the classification process, as well as problems in integrating this new diagnosis into diagnosis-related group (DRG) systems of financial reimbursement are discussed.
