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.

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.

Unfortunately, sharp, severe pain in the area of distribution of the fifth cranial nerve is frequently termed trigeminal neuralgia, and no differentiation is made between typical and atypical neuralgia and other types of facial pain disorders. This can lead to inadequate treatment. ⋯ The process of differential diagnosis is critical in trigeminal neuralgia, because an incorrent or missed diagnosis is one of the most frequent causes of treatment failure. As idiopathic trigeminal neuralgia, craniomandibular disorders or the cervical spine syndrome can involve similar symptoms and response to the use of medication, close interdisciplinary cooperation in the process of diagnosis is recommended.
