1. The nervous and immune systems communicate with each other by use of cytokines and neuropeptides. 2. Interactions between immune cell-derived opioid peptides and opioid receptors located in peripheral inflamed tissue lead to endogenous analgesia.…

This article surveys worldwide medical, ethical, and legal trends and initiatives related to the concept of pain management as a human right. This concept recently gained momentum with the 2004 European Federation of International Association for the…

The purpose of this study was to evaluate the need for pain medication and the adequacy or inadequacy of the analgesia achieved, in children with cancer who died while in terminal care. Of the 100 pediatric patients with cancer treated at the…

BACKGROUND: Morphine-6-glucuronide (M-6-G) and morphine-3-glucuronide (M-3-G) are the two most important metabolites of morphine. Both are pharmacologically active, however, with different effects. M-6-G has been demonstrated capable of inducing…

In appropriately selected patients, PCA safely provides analgesia superior to that obtained with traditional IM prn opioid administration; however, to date, no compelling evidence shows that PCA is associated with a reduction in morbidity or a more…

BACKGROUND: Methadone is a very useful drug in cancer pain because of its low cost, lack of active metabolites, high oral availability, and the rapid onset of its analgesic effect. It seems to be well tolerated in patients with difficult pain…

A reliable estimation of prognosis in patients receiving palliative care is desirable in order to facilitate clinical decision finding. For patients with advanced hematological malignancies, only few data are available to estimate prognosis of the…

The past decade has brought about an explosion of knowledge about the physiology of nociception and many new techniques for pain relief, new analgesic drugs, and new applications of old analgesic drugs. These techniques include methods of opioid…

Sedation with analgesia is frequently required to perform painful or invasive procedures in children. The best medication combination for pediatric sedation with analgesia is yet to be identified. Sixty-four of 243 total sedation with analgesia…

BACKGROUND: Codeine analgesia is wholly or mostly due to its metabolism to morphine by the cytochrome P450 enzyme CYP2D6, which shows significant genetic variation in activity. The aims of this study were to investigate genotype, phenotype and…

Traditionally, opioids have been administered as fixed doses at fixed dose intervals. This approach has been largely ineffective. Patient-controlled analgesia (PCA) and upgraded traditional approaches incorporating flexibility in dose size and dose…

Introduction Previous studies by Gourlay and coworkers1-3 have demonstrated that in adults undergoing surgery, methadone has slow elimination and a very long duration of effective analgesia. For children, intramuscular injections are a major source…

INTRODUCTION: Opioid-related mortality appears to be increasing in Canada. We examined the true extent of the problem and the impact of the introduction of long-acting oxycodone. METHODS: We examined trends in the prescribing of opioid analgesics in…

Opioids are often prescribed to children for pain relief related to procedures, acute injuries, and chronic conditions. Round-the-clock dosing of opioids can produce opioid dependence within 5 days. According to a 2001 Consensus Paper from the…

1. The management of chronic pain should be directed by the underlying cause of the pain. Whatever the cause, the primary goal of patient care should be symptom control. 2. Opioid treatment should be considered for both continuous neuropathic and…

Bisphosphonates have become standard treatment in management of malignancy-induced hypercalcemia and malignant bone pain. One obstacle to the routine use of bisphosphonates in palliative patients is that oral bisphosphonates have low bioavailability…

PURPOSE: To evaluate the clinical benefits of switching from morphine to oral methadone in patients who experience poor analgesia or adverse effects from morphine. PATIENTS AND METHODS: Fifty-two consecutive cancer patients receiving oral morphine…

PURPOSE: To define the dose ratio between morphine and methadone in relation to the previous morphine dose and the number of days needed to achieve the same level of analgesia in a group of patients with advanced cancer with pain who switched from…

The principle of double effect is used to justify the administration of medication to relieve pain even though it may lead to the unintended, although foreseen, consequence of hastening death by causing respiratory depression. Although a review of…

Morphine is the strong opioid of choice in the management of moderate-to-severe chronic cancer pain. The preferred route of administration is oral, in individually titrated doses, regularly scheduled around the clock We conducted a retrospective…

The management of pain in children with life-limiting illnesses is complex and unfortunately not often done effectively. Pain is a multidimensional symptom that can overshadow all other experiences of both the child and family. This article focuses…

The opiate hypothesis maintains that patients engage in self-injurious behavior (SIB) either because they are partially analgesic (pathologically altered pain threshold) or because SIB supplies a "fix" for an addicted endogenous opiate system. The…

A 15-year-old girl with combined immune deficiency syndrome, diagnosed with metastatic squamous cell cancer of the anus, had significant pain secondary to vulvar-perianal condyloma. Conventional treatment with oral and intravenous analgesics was…

Tramadol (Ultram, Ortho-McNeil Pharmaceutical, Inc., Raritan, NJ) is considered a Step 2 analgesic under the World Health Organization's guidelines for the treatment of patients with cancer pain. It is a centrally acting analgesic that has affinity…

This multicentre, observational study examined the efficacy of the therapeutic transdermal fentanyl system (TTS-fentanyl) in children requiring opioids for pain in life-threatening disease. Forty-one children receiving oral morphine (median dose 60…
