BACKGROUND.When a change of opioid is considered, equianalgesic dose tables

This qualitative study investigated the meaning of sexuality to palliative patients. Face-to-face interviews were conducted with ten patients receiving care in a tertiary palliative care unit, a hospice or by palliative home care services in their homes. Several themes emerged. Emotional connection to others was an integral component of sexuality, taking precedence over physical expressions. Sexuality continues to be important at the end of life. Lack of privacy, shared rooms, staff intrusion and single beds were considered barriers to expressing sexuality in the hospital and hospice settings. Only one subject had previously been asked about sexuality as part of their clinical care, yet all felt that it should have been brought up, especially after the initial cancer treatments were completed. Home care nurses and physicians were seen as the appropriate caregivers to address this issue. Subjects unanimously mentioned that a holistic approach to palliative care would include opportunities to discuss the impact of their illness on their sexuality.

Research related to spirituality and health has developed from relative obscurity to a thriving field of study over the last 20 years both within palliative care and within health care in general. This paper provides a descriptive review of the literature related to spirituality and health, with a special focus on spirituality within palliative and end-of-life care. CINAHL and MEDLINE were searched under the keywords "spirituality" and "palliative." The review revealed five overarching themes in the general spirituality and health literature: (1) conceptual difficulties related to the term spirituality and proposed solutions; (2) the relationship between spirituality and religion; (3) the effects of spirituality on health; (4) the subjects enrolled in spirituality-related research; and (5) the provision of spiritual care. While the spirituality literature within palliative care shared these overarching characteristics of the broader spirituality and health literature, six specific thematic areas transpired: (1) general discussions of spirituality in palliative care; (2) the spiritual needs of palliative care patients; (3) the nature of hope in palliative care; (4) tools and therapies related to spirituality; (5) effects of religion in palliative care; and (6) spirituality and palliative care professionals. The literature as it relates to these themes is summarized in this review. Spirituality is emerging largely as a concept void of religion, an instrument to be utilized in improving or maintaining health and quality of life, and focussed predominantly on the "self" largely in the form of the patient. While representing an important beginning, the authors suggest that a more integral approach needs to be developed that elicits the experiential nature of spirituality that is shared by patients, family members, and health care professionals alike.

Clinicians involved in the opioid pharmacotherapy of cancer-related pain should be acquainted with a variety of opioids and be skilled in the selection of doses when the type of opioid or route of administration needs changing. The optimal dose should avoid under-dosing or overdosing, both associated with negative outcomes for the patient. Although equianalgesic dose tables are generally used to determine the new doses in these circumstances, the evidence to support the ratios indicated in these tables largely refers to the context of single dose administration. The applicability of these ratios to the setting of chronic opioid administration has been questioned. A systematic search of published literature from 1966 to September 1999 was conducted to critically appraise the emerging evidence on equianalgesic dose ratios derived from studies of chronic opioid administration. There were six major findings: 1) there exists a general paucity of data related to long-term dosing and studies are heterogeneous in nature; 2) the ratios exhibit extremely wide ranges; 3) methadone is more potent than previously appreciated; 4) the ratios related to methadone are highly correlated with the dose of the previous opioid; 5) the ratio may change according to the direction the opioid switch; and 6) discrepancies exist with respect to both oxycodone and fentanyl. Overall, these findings have important clinical implications for clinicians and warrant consideration in the potential revision of current tables. The complexity of the clinical context in which many switches occur must be recognized and also appreciated in the design of future studies.

This was the first known study that focused specifically on the exploration of a collective spirituality. The culture of palliative care seems to foster spiritual reflection among health care professionals both as individuals and as a whole. While spirituality was difficult to describe, it was a shared experience often tangibly present in the provision of care on all levels.

The fact that methadone ratio is different according to the opioid dose used previously should be taken into careful consideration by the clinician in order to avoid severe toxicity or death during switchover. Prospective studies should be carried out in order to better define our findings.

A 62-year-old man receiving subcutaneous fentanyl for the management of cancer pain developed generalized central excitation after an overdose of 5000 micrograms of fentanyl. The patient developed acute confusion, restlessness, generalized myoclonus, visual hallucinations, and hyperalgesia and tremors upon tactile stimulation of the arms or legs. These symptoms rapidly disappeared after the administration of 0.2 mg of naloxone. Within an hour the symptoms reappeared and once again, responded immediately after a second injection of 0.2 mg of naloxone. Our findings suggest that fentanyl overdose can occasionally present with general central irritability that responds to naloxone.

Most cancer patients will experience pain requiring opioid therapy during their illness. Standard opioid therapy includes fixed scheduled doses and so-called "rescue" doses for breakthrough pain. Circadian rhythms seem to influence the expression of pain and the responsiveness to analgesic medication. Delirium is a common complication in advanced cancer patients and it also may modify the expression of pain and the use of analgesic medication. We reviewed the circadian distribution of breakthrough analgesia (BTA) doses in 104 advanced cancer patients who were part of a prospective study of the occurrence of delirium. We found that the circadian distribution of BTA is significantly different from a random distribution in the case of patients with and without delirium. Patients without delirium tended to use more BTA (P < 0.001) in the morning, whereas patients with delirium tended to use more BTA in the evening and at night (P = 0.02). We conclude that delirium is associated with changes in the circadian distribution of BTA, which is possibly related to reversal of the normal circadian rhythm.
