Cannabis in palliative care: current challenges and practical recommendations.

Pain and symptom control challenges are common in palliative care, and the search for other therapeutic strategies is ongoing. Unfortunately, patients and their caregivers are receiving little information or support from healthcare providers regarding the increasingly popular cannabinoid-based medicines (CBM). Clinicians, meanwhile, feel understandably perplexed by the discrepancy between the available evidence and the rapid interest in which patients and their families have demonstrated for CBM. There is an urgent need to address the many challenges that are delaying the appropriate integration of CBM into clinical practice, notwithstanding the obvious need for a solid general knowledge of pharmacology, mechanism of action and available clinical evidence supporting its use. The authors will address these challenges and provide practical recommendations regarding patient assessment for the use of CBM. The authors will also make suggestions regarding patient expectations in order to define clear objectives, review the necessary precautions prior to initiating treatment, aid in selecting the appropriate strain and route of administration as well as establishing proper titration and monitoring protocols. The authors will also discuss the lesser known but potentially therapeutic psychoactive effects of cannabis. As this class of therapeutic agents are likely to play a major role in palliative medicine in the near future, clinicians would benefit from familiarizing themselves with CBM and we can expect that patients and their caregivers will appreciate receiving support in their search for safe and effective therapeutic alternatives.

Effects of relaxing therapies on patient's pain during percutaneous interventional radiology procedures.

BACKGROUND: Interventional radiology procedures in cancer patients cause stress and anxiety. Our objective was to relate our experience in the use of sophrology techniques during interventional radiology procedures and evaluate the effects on patient's pain and anxiety. METHODS: We present a prospective observational study on 60 consecutive patients who underwent interventional radiology procedures in a context of oncologic management from September 2017 to March 2018. Forty-two patients were asked if they wished to benefit from the sophrology and hypnosis techniques during their procedure. A control group was also made including 18 patients. Anxiety level and pain were evaluated using the visual analog scale (VAS) before and during procedures. RESULTS: We observed a significant decrease in anxiety experienced by patients during interventional radiology procedures compared to before procedures in the sophrology group (P=3.318E-08), and a level of anxiety and pain during gestures inferior to that of the control group (P=2.035E-06 and 7.03E-05 respectively). CONCLUSIONS: Relaxing therapies, such as sophrology and hypnosis, seems to be an interesting additional tool for the management of patients in interventional oncology, inducing a decrease of stress, pain, and anxiety in patients.

[Case management based multidisciplinary care protocol in the palliative care of cancer patients]. / Kanser hastasinin palyatif bakiminda vaka yönetimine dayali multidispliner bakim protokolü.

Today, multifaceted approach is needed for the palliative care of advanced stage cancer patients. The main objective for these patients, elimination of pain and other symptoms, psychosocial and spiritual needs are met and to increase the quality of life. We are also faced with the challenge of meeting the physical and psychosocial needs of family members. The purpose of a holistic approach to patient and family who provide effective and quality care, care coordination and case management of a multidisciplinary team approach is based on cooperation. Care protocols specified patient care activities to be carried by the related disciplines to achieve results on a timeline that shows a certain, a multidisciplinary clinical management tool. A lot of care guidelines and protocols developed by a team of experts to contribute to the palliative care activities, and this is thought to be a guiding team members, working with patients.

Treatment of chronic, intractable pain with a conventional implantable pulse generator: a meta-analysis of 4 clinical studies.

OBJECTIVE: To provide further short-term (6 mo) and long-term (1 y) evidence for the use of spinal cord stimulation (SCS) with a conventional implantable pulse generator in the management of chronic, intractable pain. MATERIALS AND METHODS: We conducted a meta-analysis of 4 prospective, multicenter studies that collected outcome data from patients implanted with SCS to treat chronic pain of the trunk and/or limbs (Genesis IPG system). Two of these were conducted as long-term studies lasting 1 year, and 2 as shorter term studies lasting 6 months. A total of 300 patients from 28 investigational sites were prospectively evaluated for efficacy at 3 months after implant and safety at 6 months after implant. None of the sites participated in more than one study. Outcome measures included patient-reported percent of pain relief, patient satisfaction, quality of life improvement, pain evaluation (0 to 10 rating), pain relief rating, Short-Form McGill Pain Questionnaire, visual analog scale, the Short Form-36, and the total number of adverse events (AEs). RESULTS: At 3 months after implantation of the permanent system, 75.4% of the patients (190/252) reported a 50% or greater pain relief as determined by the patient-reported degree of pain relief. Similarly, assessment of patient satisfaction with SCS therapy showed that 86.1% of patients (217/252) in all 4 studies were satisfied or very satisfied with the therapy at 3 months. In the 2 long-term studies, 80.9% of patients (140/173) were satisfied or very satisfied with the therapy at the 1-year evaluation point. Quality-of-life (QoL) data indicated that at 3 months after implant, 77.8% of patients (196/252) reported QoL as improved or greatly improved. Similarly, QoL was improved or greatly improved for 74.0% patients in the long-term study at 1 year (128/173). In the safety analysis, AEs were reviewed for all 4 studies. A total of 190 AEs were reported in 117 of 300 patients during all studies. CONCLUSIONS: This analysis provides further evidence of the safety and effectiveness of SCS in treating chronic intractable pain of the trunk and/or limbs. Specifically, it underscores a high level of effectiveness and acceptable safety concerns in the use of nonrechargeable SCS devices.

Hypnosis for cancer care: over 200 years young.

Answer questions and earn CME/CNE Hypnosis has been used to provide psychological and physical comfort to individuals diagnosed with cancer for nearly 200 years. The goals of this review are: 1) to describe hypnosis and its components and to dispel misconceptions; 2) to provide an overview of hypnosis as a cancer prevention and control technique (covering its use in weight management, smoking cessation, as an adjunct to diagnostic and treatment procedures, survivorship, and metastatic disease); and 3) to discuss future research directions. Overall, the literature supports the benefits of hypnosis for improving quality of life during the course of cancer and its treatment. However, a great deal more work needs to be done to explore the use of hypnosis in survivorship, to understand the mediators and moderators of hypnosis interventions, and to develop effective dissemination strategies.

The management of cancer-related breakthrough pain: recommendations of a task group of the Science Committee of the Association for Palliative Medicine of Great Britain and Ireland.

A task group of the Science Committee of the Association for Palliative Medicine of Great Britain and Ireland (APM) was convened to produce some up-to-date, evidence-based, practical, clinical guidelines on the management of cancer-related breakthrough pain in adults. On the basis of a review of the literature, the task group was unable to make recommendations about any individual interventions, but was able to make a series of 12 recommendations about certain generic strategies. However, most of the aforementioned recommendations are based on limited evidence (i.e., case series, expert opinion). The task group also proposed a definition of breakthrough pain, and some diagnostic criteria for breakthrough pain.

Opioids in context: relieving the pain of cancer. The role of comprehensive cancer management.

Optimal pain control requires detailed appraisal of each symptom; in many cases definitive treatment of the underlying cause will be the most effective means of pain control. As an example back pain may be due not only to bone metastases but also enlarging lymph nodes, renal pain or retroperitoneal tumour. Benign causes including degenerative joint disease should also be considered and each cause treated specifically alongside the use of analgesics.

Combined antioxidant therapy reduces pain and improves quality of life in chronic pancreatitis.

Patients with chronic pancreatitis (CP) typically suffer intractable abdominal pain that is resistant to most analgesic strategies. Recent research indicates that the pain of CP may be in part due to oxygen free radical induced pancreatic damage. Using a randomized, double-blind, placebo-controlled crossover trial, we evaluated the efficacy of a combined antioxidant preparation in the management of CP. Patients with confirmed chronic pancreatitis (N = 36) were randomized to receive treatment with either Antox, which contains the antioxidants selenium, betacarotene, L-methionine, and vitamins C and E, or placebo for 10 weeks. Each group of patients then switched to receive the alternative treatment for a further 10 weeks. Markers of antioxidant status were measured by blood sampling, whereas quality of life and pain were assessed using the SF-36 questionnaire. Nineteen patients completed the full 20 weeks of treatment. Treatment with Antox was associated with significant improvements in quality of life in terms of pain (+17 antioxidant vs. -7 placebo), physical (+9 vs. -3) and social functioning (+8 vs. -7), and general health perception (+10 vs. -3). We conclude that treatment with antioxidants may improve quality of life and reduce pain in patients suffering from chronic pancreatitis.

Cannabinoids and cancer: causation, remediation, and palliation.

This review discusses three different associations between cannabinoids and cancer. First, it assesses evidence that smoking of cannabis preparations may cause cancers of the aerodigestive and respiratory system. There have been case reports of upper-respiratory-tract cancers in young adults who smoke cannabis, but evidence from a few epidemiological cohort studies and case-control studies is inconsistent. Second, there is mixed evidence on the effects of THC and other cannabinoids on cancers: in some in vitro and in vivo studies THC and some synthetic cannabinoids have had antineoplastic effects, but in other studies THC seems to impair the immune response to cancer. As yet there is no evidence that THC or other cannabinoids have anticancer effects in humans. Third, Delta(9)-tetrahydrocannabinol (THC) may treat the symptoms and side-effects of cancer, and there is evidence that it and other cannabinoids may be useful adjuvant treatments that improve appetite, reduce nausea and vomiting, and alleviate moderate neuropathic pain in patients with cancer. The main challenge for the medical use of cannabinoids is the development of safe and effective methods of use that lead to therapeutic effects but that avoid adverse psychoactive effects. Furthermore, medical, legal, and regulatory obstacles hinder the smoking of cannabis for medical purposes. These very different uses of cannabinoids are in danger of being confused in public debate, especially in the USA where some advocates for the medical use of cannabinoids have argued for smoked cannabis rather than pharmaceutical cannabinoids. We review the available evidence on these three issues and consider their implications for policy.

Complementary and alternative therapies to manage HIV-related symptoms.

Persons with HIV infection report substantial use of complementary and alternative medical (CAM) therapies for symptom management. Anecdotal reports from patients indicate that CAM approaches are helpful; however, there is limited scientific information on the safety and efficacy of these therapies in the HIV population. The purpose of this review is to critically appraise the scientific evidence for selected CAM therapies that are used by HIV-infected persons to manage three common symptoms: nutritional alterations, pain, and depression.

Neuropathic pain--from mice to men.

The past decade has seen great progress in understanding the syndrome of neuropathic pain, its causes and in finding new drugs that promise great benefit. For example, an early outcome of the research has been the observation that the new drugs do not blunt normal pain sensation--a pattern beginning to find explanation through the realisation that neural pain circuits rewire themselves, both anatomically and biochemically, after nerve injury. In this article, we discuss a case of a known diabetic patient with intractable pain and the course of management provided by the use of novel tools and devices coming to the fore in this rapidly expanding specialty.

Easing cancer pain through treatment options.

The diagnosis of life-threatening illness delivers patients and families into new and often unfamiliar territory--a place one author has named "the country of illness." There are no easy road maps in that new world, and the way is made harder by the burdens thrust upon its inhabitants. For cancer patients, one of the greatest burdens is the pain that comes with the disease.

Relaxation for the relief of chronic pain: a systematic review.

The effectiveness of relaxation techniques in the management of chronic pain was determined in this systematic review of published randomized controlled trials. Reports were sought by searching MEDLINE, psycLIT, CINAHL, EMBASE and the Oxford Pain Relief Database. Studies were included in this review if they were randomized controlled trials of relaxation techniques in chronic pain. Studies which investigated the effects of relaxation in combination with other interventions were not considered. Nine studies involving 414 patients met the predefined inclusion criteria and are critically appraised in this review. Meta-analysis was not possible, due to lack of quantitative data in the primary studies. Studies involved patients with a range of chronic pain conditions. The McGill Pain Questionnaire was the most common pain outcome used. Whilst four studies were able to show a significant difference for the pain outcomes in favour of relaxation for the pre- and post-treatment assessments, few statistically significant differences were reported in favour of relaxation when between treatment comparisons were used. Only three studies reported statistically significant differences in favour of relaxation (judged as a significant difference for at least 1 of the pain outcomes) compared to the other treatment groups. In rheumatoid arthritis the McGill Pain Questionnaire scores were significantly lower for patients receiving relaxation compared to those who were in the routine treatment control group. In ulcerative colitis significant differences were reported for six of seven different pain outcome measures in favour of progressive muscle relaxation compared to patients in the waiting list control group. In one of the two cancer pain studies, relaxation taught by nurses produced significantly lower pain sensation scores compared to the control group. Two studies reported significant differences in favour of the experimental control groups rather than for relaxation. There is insufficient evidence to confirm that relaxation can reduce chronic pain. Many of the studies both positive and negative suffer methodological inadequacies. Recommendations for future research into the effectiveness of relaxation techniques for chronic pain are made.
