Randomized Controlled Trial
The Pharmacokinetics, Efficacy, and Safety of a Novel Selective-Dose Cannabis Inhaler in Patients with Chronic Pain: A Randomized, Double-Blinded, Placebo-Controlled Trial.
Precise cannabis treatment dosing remains a major challenge, leading to physicians' reluctance to prescribe medical cannabis. ⋯ Evidence suggests that cannabis-based medicines are an effective treatment for chronic pain in adults. The pharmacokinetics of THC varies as a function of its route of administration. Pulmonary assimilation of inhaled THC causes rapid onset of analgesia. However, currently used routes of cannabinoids delivery provide unknown doses, making it impossible to implement a pharmaceutical standard treatment plan. A novel selective-dose cannabis inhaler delivers significantly low and precise doses of THC, thus allowing the administration of inhaled cannabis-based medicines according to high pharmaceutical standards. These low doses of THC can produce safe and effective analgesia in patients with chronic pain.

Randomized Controlled Trial
Effects of a person-centred approach in a school setting for adolescents with chronic pain - The HOPE randomized controlled trial.
Chronic pain among adolescents is common but effective interventions applicable in a school setting are rare. Person-centred care (PCC) is a key factor in improving health by engaging persons as partners in their own care. ⋯ This study evaluates the effects of a pain management programme based on a PCC approach in a school setting addressing adolescents at upper secondary and secondary schools with chronic pain. No overall effects were shown, but results illustrate that the intervention improved self-efficacy in adolescents at secondary school. Implementation of a PCC approach in a school setting may have the potential to improve self-efficacy in daily activities for adolescents with chronic pain at secondary school.

Cervical dystonia is the most common form of focal idiopathic dystonia and is frequently associated with pain. Headaches are not considered to be more prevalent among patients presenting with cervical dystonia, and headaches attributed to craniocervical dystonia are considered to be a rare disorder, despite the lack of studies and clinical information regarding the subject. ⋯ We found that headaches are more frequent among patients with cervical dystonia than previously thought, and that they contribute towards an overall increase in pain in these patients. Headaches attributed to craniocervical dystonia are associated with greater disability among patients with cervical dystonia. These headaches improve after botulinum toxin injections, in parallel with the improvement of cervical dystonia symptoms.

Opioid use has increased to epidemic levels over the past decade within the United States, particularly among vulnerable populations. This retrospective study aimed to evaluate rates of prolonged opioid use in the Veteran population after thoracic surgery and identify specific risk clusters. ⋯ This article presents population-level chronic opioid use trajectories after thoracic surgery, using latent class structures. Demographics, preoperative psychological diagnoses, medication usage and chronic pain variables were utilized to identify population-level clusters. The cluster identified as highest risk had preoperative chronic opioid use, psychological diagnoses, other medication prescriptions and chronic pain.

Pain is common and refractory in spinal cord injury (SCI). Currently, most studies evaluated pain in male-predominant traumatic-SCI. Also, concomitant secondary pain syndromes and its temporal evolution were seldom reported. ⋯ In this longitudinal study with NMO-related SCI, pain affected almost three-quarters of patients with NMO. Over 70% have more than one pain syndrome and at-level neuropathic pain is the most common type of pain syndrome. Patients without pain were significantly younger but had the same burden of inflammatory lesions than those with pain. During follow-up, up to one fifth of patients presented with changes in the main pain syndromes, which can occur even in the absence of clinical activity of the inflammatory disease. In this cohort, Pain affected quality of life as much as disability or motor strength.
