Case ReportsMethadone analgesia in cancer pain patients on chronic methadone maintenance therapy.
Methadone is currently best known for its use as the maintenance drug in opioid addiction. The main concern when using methadone for the treatment of pain is its long and unpredictable half-life, which is associated with the risk of delayed toxicity. This may result in side effects such as sedation and respiratory depression if careful titration and close observation of individual patient responses are not performed. ⋯ The first five patients were at least partially refractory to the analgesic effects of opioids other than methadone. All six patients achieved analgesia without sedation or respiratory depression from aggressive upward methadone titration. Methadone analgesia can be considered early in the course of treatment of patients with chronic exposure to methadone who develop new or worsening pain requiring opioid therapy.

Economic evaluation of the fentanyl transdermal system for the treatment of chronic moderate to severe pain.
The fentanyl transdermal system (Duragesic) is an opioid analgesic indicated for the management of chronic moderate to severe pain. The purpose of this analysis is to estimate its economic value compared to two long-acting oral opioids. A cost-utility analysis was performed using a three-phased decision analytic model. ⋯ The fentanyl transdermal system achieved incremental cost-utility ratios of $20,709 (vs. morphine) and $5,273 (vs. oxycodone) per quality-adjusted life year (QALY) gained. In a conservative modeled analysis, the fentanyl transdermal system led to increased QALDs at a nominal increased cost. In the absence of head-to-head clinical trials, models help clarify cost and outcome trade-offs and provide a consistent theoretical framework for use by individual decisionmakers.

Breathlessness leading to exercise limitation is common in patients with advanced cancer and is ineffectively treated. There are few research data to guide clinicians on best practice. The shuttle walking test has been validated for some conditions such as chronic obstructive pulmonary disease but not for advanced cancer. One of the well documented difficulties of doing clinical research in palliative care is the acceptability of assessment tests. This study examined the reproducibility of the shuttle walking test in patients with advanced cancer to help facilitate the systematic evaluation of interventions designed to improve breathlessness. ⋯ The shuttle walking test is a reproducible test of functional capacity in ambulant patients with advanced cancer, WHO performance status 1 or 2. The data indicate that a practice session is needed. It is easy to carry out and acceptable for patients with advanced cancer.

Chronic pain is an important problem following spinal cord injury (SCI) and is a major impediment to effective rehabilitation. The reported prevalence of chronic SCI pain is variable but averages 65% with around one third of these people rating their pain as severe. The mechanisms responsible for the presence of pain are poorly understood. ⋯ Current treatments employ a variety of pharmacological, surgical, physical and psychological approaches. However, evidence for many of the treatments in use is still limited. It is hoped that future research will identify effective treatment strategies that accurately target specific mechanisms.
