The series of publications is continued in which the results of a review of German pain-related psychological assessment tools are presented. The taskforce of the German Society for the Study of Pain (DGSS) describes and examines instruments assessing the qualitative aspects of how pain is experienced (part II). Part III describes and comments on methods regarding self-reporting and observation of pain behaviour. Part IV discusses the use of pain diaries and introduces different forms of diaries, focussing on the measurement of pain intensity.

An expert committee of the German Chapter of the IASP has published five recommendations for the prevention and early treatment of low back pain. These refer to an early activation of the patient facilitated by scheduled pain medication and an interdisciplinary treatment including physiotherapy and psychotherapy if risk factors for chronicity are detected.

Effective treatment of patients with trigeminal neuralgia is often a long and complicated procedure. The symptoms of trigeminal neuralgia are clearly defined in most cases. Sudden and brief episodes of severe and stabbing pain (tic douloureux) occur, with pain usually starting from a trigger point. Recent reports suggest 80-90% suppression of pain with various treatment regimens, which seems to indicate that the diagnosis and successful treatment of the disorder are no longer a major problem. In fact, however, the intense suffering of patients and isolated reports in the literature suggest that there are still considerable diagnostic difficulties. Patients are referred from one specialist to another, in most cases without the necessary interdisciplinary cooperation, and countless interventions and attempts at therapy not only remain unsuccessful, but may cause serious adverse effects. ⋯ Apparently there is a considerable need for more information about the clinical symptoms, cause, diagnosis and therapy of trigeminal neuralgia, especially as the symptoms are often no longer typical because they have become chronic or are the result of previous treatment. This is needed by all specialists involved, including dentists and general practitioners. In patients in whom clinical criteria suggest the diagnosis of trigeminal neuralgia, drug treatment should be initiated immediately in consultation with the neurologist or neurosurgeon. For cases in which drug treatment fails or resistance to the drug develops surgical treatments are available, such as non-destructive microvascular decompression or thermocoagulation of the gasserian ganglion.

This is the first in a series of publications presenting the results of a taskforce on quality assurance in psychological assessment of chronic pain. The initiative was motivated by the increasing and confusing variety of newly developed German instruments and/or translations of Anglo-American instruments. Our main work was therefore concentrated on the collection of existing German assessment instruments, on summarizing the essentials in a documentary sheet, and on examining their objectivity, reliability, validity, clinical relevance, economy and degree of empirical foundation. For each diagnostic domain we thus elaborated specific differential recommendations for those working in psychological pain research and clinical practice, in an attempt to devise criteria enabling them to choose the optimal instrument or test battery for their needs and conditions.

The adequate use of opioids in the treatment of chronic cancer pain requires sound knowledge of selection criteria for the various opioids, the routes of administration, dosages, dosing schemes and possible side effects. Drug selection depends on the intensity of pain rather than on the specific pathophysiology. Mild to moderate pain can often be treated effectively by so-called "weak" opioids. ⋯ True dependence or psychological addiction rarely occurs in patients with chronic cancer pain. In most cases, progression of the underlying disease associated with increasing tissue damage and increasing pain is found. Fear of dependence and addiction often contributes to undertreatment of patients suffering from chronic cancer pain.
