Practice Guideline
Recognition and management of iatrogenically induced opioid dependence and withdrawal in children.
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. ⋯ Guidance on this subject is available only for adults and primarily for adults with substance use disorders. The guideline will summarize existing literature and provide readers with information currently not available in any single source specific for this vulnerable pediatric population.

Voices that may not otherwise be heard: a qualitative exploration into the perspectives of primary care patients living with chronic pain.
Although psychometrically sound pain assessment tools are available, there is a paucity of research that comprehensively defines chronic pain from the perspective of patients. The purpose of this study was to examine the utility of a combination of qualitative methods (Photovoice, one-on-one interviews, and focus groups) in examining the daily experiences of primary care patients living with chronic pain. ⋯ The qualitative methods employed in this study provide deep insight into perceptions and experiences of patients living with chronic pain that is vital for informing future clinical interventions.

Two different patterns of breathlessness have been identified: chronic or continuous breathlessness and breathlessness crisis (acute, incident, episodic, breakthrough breathlessness). Meta-analysis and systematic reviews prove that opioids are beneficial in either opioid-naïve or -tolerant patients. However, data from two recent randomised controlled trials were not able to show the effectiveness of fentanyl for the relief of exertion-induced dyspnoea.

Clinical evaluation of the efficacy of methylnaltrexone in resolving constipation induced by different opioid subtypes combined with laboratory analysis of immunomodulatory and antiangiogenic effects of methylnaltrexone.
Opioid-induced constipation (OIC) is one of the major symptoms in palliative care with a prevalence of 30-50%. Methylnaltrexone for the treatment of OIC is significantly more effective than placebo, but only in about fifty percent of the patients regardless of dose increase. Dose increases cause increased toxicity without additional efficacy, and are therefore not recommended. While methylnaltrexone is a μ-receptor antagonist, only a few opioids are solely μ-receptor agonists. Therefore, the response to methylnaltrexone may be determined by the receptor-profile of a specific opioid. In addition, methylnaltrexone may also affect the immune system and angiogenesis as was found in pre-clinical studies. Primary aim of this study is to determine differences in the efficacy of methylnaltrexone prescribed to resolve opioid induced constipation between three commonly used opioid subtypes: morphine sulphate, oxycodone and fentanyl. Secondary aim is to explore potential immunomodulatory and antiangiogenic effects of methylnaltrexone. ⋯ In this study we aim to determine the efficacy of methylnaltrexone per opioid subtype to reduce constipation. We expect that the outcome of this study will improve the clinical use of methylnaltraxone.

Opioid-induced constipation in patients with chronic noncancer pain in the USA, Canada, Germany, and the UK: descriptive analysis of baseline patient-reported outcomes and retrospective chart review.
The characteristics of patients who suffer from noncancer pain and opioid-induced constipation are not well understood. ⋯ Patients treated with opioids for noncancer pain commonly endure constipation symptoms that limit their work productivity and overall health-related quality of life while adhering to treatments that provide little relief. Further research is needed to identify more efficacious constipation therapies for this patient population.
