Whether acute, chronic or recurrent, facial pain remains an therapeutic challenge. Neurological tests, otorhinolaryngologic, dental or psychiatric examinations do not always provide a precise diagnosis. We propose a review of painful diseases most often found in the head and neck region. A differential diagnosis between psychiatric and functional diseases is proposed although the subjective component is always present. Neuralgias, migraine, cluster headache, tension-type headache, atypical facial pain and cancer pain are reviewed.

While various aspects of the physical examination in pain patients have been validated, the value of screening maneuvers that reproduce a cancer patient's pain on physical examination has been less well defined. The purpose of this prospective case series is to better characterize the role of bedside provocative maneuvers as part of the comprehensive evaluation of cancer pain patients. Fifty consecutive patients referred to an ambulatory cancer pain clinic were evaluated; they described a total of 89 discrete pains. All or much of the pain that brought each patient to medical attention was reproduced by a provocative maneuver in 47 (94%) patients; 79 of 89 (89%) pains were elicited at the bedside. Pains that were not reproducible with any provocative maneuver included paroxysmal spells of pain, neuropathic pain, and steady headache. On the basis of the history, physical examination, and both positive and negative provocative maneuvers, all pains were characterizable as somatic, visceral, neuropathic, or mixed, and a pathophysiological basis for the pain was inferred in 85 of 89 (95%) pains. On the basis of this preliminary report, we conclude that provocative bedside maneuvers are usually able to reproduce a cancer patient's pain. They help to better characterize the pain and identify the pain sensitive structure, and should be a routine part of the comprehensive assessment of cancer pain patients. Further research is needed to validate the diagnostic role of standardized pain-provoking maneuvers in a variety of clinical situations.

In a regional pain management network in Cologne, the pain clinic of the department of anaesthesiology and the departments of psychosomatic medicine and of informatics, statistics and epidemiology have been cooperating with the regional board of physicians and more than 80 general practitioners since 1996. The program is sponsored by the German Ministry of Health. In this network, guidelines for the management of chronic pain have been implemented for outpatient care in the last three years. Results from the first year confirm the high level of distress of patients with chronic pain. Consultation and education offered by the coordinating office and in training courses were accepted by the practitioners in variable degrees. Some physicians requested consultations frequently while including only a few patients in the study documentation, while other physicians requested consultations rarely and assessed many patients. Participating physicians were also asked to provide analgesic regimens for constructed case reports with chronic headache or cancer pain. The evaluation of these prescriptions showed poor adherence to analgesic guidelines.

Neurosurgeons have successfully used punctate midline myelotomy to relieve visceral cancer pain in human patients. Animal experiments demonstrate a visceral nociceptive pathway in the posterior column that is more effective than the spinothalamic tract in activating thalamic neurons, eliciting behavioral responses and triggering increases in regional cerebral blood flow. This visceral nociceptive pathway involves postsynaptic dorsal column neurons in the central, visceral processing region of the spinal cord. Axons from the sacral cord ascend near the midline and from the thoracic cord at the junction of the gracile and cuneate fasciculi.

Ever since the application in 1980 of morphine for spinal analgesia in patients with refractory cancer pain, spinal infusion therapy has become one of the cornerstones for the management of chronic, medically intractable pain. Initially, spinal infusion therapy was indicated only for patients with cancer pain that could not be adequately controlled with systemic narcotics. However, over the past decade, there has been a significant increase in the number of pumps implanted for the treatment of nonmalignant pain. Indeed, "benign" pain syndromes, particularly failed back surgery syndrome, are the most common indication for intrathecal opiates. As we have gained more experience with this therapy, it has become apparent that even intrathecal opiates, when administered in the long term, can be associated with problems such as tolerance, hyperalgesia, and other side effects. Consequently, long-term efficacy has not been as significant as had been hoped. Because of the difficulties associated with long-term intrathecal opiate therapy, much of the research, both basic and clinical, has focused on developing alternative nonopioid agents to be used either alone or in combination with opiates. Clinical trials have been and continue to be conducted to evaluate drugs such as clonidine, SNX-111, local anesthetics, baclofen, and many other less common agents to determine their efficacy and potential toxicity for intrathecal therapy. This article reviews the agents developed as alternatives to intrathecal opiates.

Control of malignant pain and related symptoms is paramount to clinical success in caring for cancer patients. To achieve the best quality of life for patients and families, oncologists and palliative care clinicians must work together to understand problems related to psychologic, social, and spiritual pain. Pain is the primary problem targeted for control using the World Health Organization's (WHO) analgesic ladder. This article focuses on increased knowledge of analgesic action that may enable expansion of the WHO analgesic ladder to fulfill the broader objectives of palliative medicine. We discuss clinical experience with several classes of drugs that are currently used to treat cancer pain: 1) nonsteroidal anti-inflammatory drugs, with emphasis on cyclooxygenase-2 inhibitors; 2) opioid analgesics, with specific emphasis on methadone and its newly recognized value in cancer pain; 3) ketamine, an antagonist at N-methyl-d-aspartate receptors; and 4) bisphosphonates, used for pain resulting from bone metastases. New concepts that compare molecular actions of morphine at excitatory opioid receptors, and methadone at nonopioid receptor systems, are presented to underscore the importance of balancing central nervous system excitatory (anti-analgesic) versus inhibitory (analgesic) influences.

In a regional pain management network in Cologne, sponsored by the German Ministry of Health, structures of outpatient pain treatment in general practice and the adherence to pain management guidelines were examined. The 3-year project was divided into a 1-year observational period to analyze the present state of outpatient pain management followed by a 2-year period of interventions such as consultations and educational training programs in pain treatment. Eighty physicians with different specializations working in general practice took part in the network. The knowledge of and adherence to the guidelines for the treatment of headache and cancer pain were examined by questionnaire surveys and six simulated patient cases. These investigations were performed yearly from 1997 to 2000. The adherence to the guidelines for the treatment of headache and cancer pain by the physicians participating in the network was low. The levels achieved for simulated cases of headache were higher than for cancer pain. The results of simulated patient cases from the beginning and the end of the project were available for comparison for 28 physicians. Evaluation of the physicians' assessment of the simulated patient cases increased only fractionally and was not significant in headache patients (median change of 0.67) and cancer pain patients (median change of 0.17). The network interventions resulted in a slight improvement in the knowledge of and attitudes to the treatment of headache and cancer pain as judged by simulated patient cases. This improvement, however, did not reach statistical significance. The small number of physicians answering at the beginning and at the end of the project made it difficult to draw a general conclusion on whether the interventions had led to an improvement in outpatient pain management in a larger group of physicians.

It is estimated that 40% to 50% of patients with metastatic disease and 90% of patients with terminal cancer experience unrelieved pain. Furthermore, inadequate treatment of cancer pain is a greater possibility if the patient is a substance abuser. In this paper, we will explore pertinent conceptual and clinical aspects of addiction that can assist in improving the identification and treatment of patients with substance use disorders.

Cancer pain is progressive and complex. The multidimensional character of cancer pain requires comprehensive management by a multidisciplinary team of health care professionals. Pharmacotherapy is a cornerstone of cancer pain management. Pharmacists who are engaged in ambulatory cancer pain management can play a pivotal role in the pharmacotherapy of cancer pain by optimizing medication therapy, monitoring outcomes, enhancing adherence through patient education regarding drug use, pain and symptom control, educating other health professionals and students, and conducting research. To fully meet the therapeutic challenges of cancer pain, pharmacists need to improve their knowledge and attitudes about cancer pain and pain medications.

Cancer pain is a significant problem despite the advent of the World Health Organization's cancer pain guidelines, the US government's cancer pain guidelines, and the Joint Commission's mandate for hospital pain evaluation and treatment. Ninety percent of patients with cancer pain can be effectively treated with oral conservative medications. The remaining 10% need more invasive treatments to control their pain. This article reviews current methods of controlling cancer pain using intrathecal catheters, nerve blocks, and neurosurgical procedures.
