The opioid antagonist naltrexone has been shown to attenuate the subjective effects of amphetamine. However, the mechanisms behind this modulatory effect are currently unknown. We hypothesized that naltrexone would diminish the striatal dopamine release induced by amphetamine, which is considered an important mechanism behind many of its stimulant properties. We used positron emission tomography and the dopamine D2-receptor radioligand [(11)C]raclopride in healthy subjects to study the dopaminergic effects of an amphetamine injection after pretreatment with naltrexone or placebo...

PURPOSE: Results of efficacy and safety assessments of topical sevoflurane use in patients with long-term treatment-refractory vascular ulcers are reported. METHODS: Patients were randomly assigned to receive sevoflurane instillations (1 mL per cm(2) of ulcer area 1-4 times daily) plus standard wound care (ulcer cleaning, debridement, and dressing changes) or standard care only. Topical sevoflurane was initiated during hospitalization, with self- or nurse-administered instillations continued after discharge...

The McGill Pain Questionnaire (MPQ) is composed of 78 words reflecting the mechanisms underlying chronic pain conditions. Ischemic ulcer pain is generally regarded as a nociceptive and inflammatory pain condition. However, it is sometimes refractory to nonsteroidal anti-inflammatory drug (NSAID) and opioid treatment. We categorized ischemic pain into nociceptive/inflammatory pain (NocP) or neuropathic pain (NeP), on the basis of patients' descriptions of their pain using the MPQ. We investigated pain characteristics of 365 patients with NeP and 124 with NocP using the 78 words of the MPQ...

BACKGROUND: Subanesthetic doses of ketamine, an N-methyl-d-aspartate receptor antagonist used as an adjuvant to opioid for the treatment of pain in adults with acute and chronic pain, have been shown, in some instances, to improve pain intensity and to decrease opioid intake. However, less is known about the role of ketamine in pain management in children, adolescents, and young adults. PURPOSE: We examined the effects of subanesthetic ketamine on pain intensity and opioid intake in children, adolescents, and young adults with acute and chronic pain syndromes treated in an inpatient setting...

Previously, we have shown that the N-methyl d-aspartate (NMDA)-receptor antagonist kynurenic acid (KYNA) and its analogue KYNA1 do not bind directly to mu, kappa and delta opioid receptors in vitro. On the other hand, chronic administration of KYNA and KYNA1 resulted in region (cortex vs striatum) and opioid receptor-type specific alterations in G-protein activation of mouse brain homogenates. Here we describe for the first time the acute effect of KYNA and KYNA1 on opioid receptor function with the possible involvement of the NMDA receptor...

BACKGROUND: Total knee arthroplasty (TKA) is associated with high rates of prolonged opioid use after surgery (10%-34%). By decreasing opioid use in the immediate postoperative period, perioperative nerve blockade has been hypothesized to decrease the risk of persistent opioid use. METHODS: Using health care utilization data, we constructed a sample of 120,080 patients undergoing TKA between 2002 and 2012 and used billing data to identify the utilization of peripheral or neuraxial blockade...

Sports-related injuries are a frequent cause of visits to the emergency department (ED) across the United States. A majority of these injuries affect the lower extremities with the ankle as the most frequently reported site. Most sports-related injuries are not severe enough to require inpatient hospitalization; however, they often lead to acute distress and pain which require prompt treatment with analgesics. Approximately 22% of patients who presented to the ED required pharmacotherapy for acute pain management...

OBJECTIVE: Chronic pain is now recognized as a neural disease, which results from a maladaptive functional and structural transformation process occurring over time. In its chronic phase, pain is not just a symptom but also a disease entity. Therefore, pain must be properly addressed, as many patients still report unsatisfactory pain control despite on-going treatment. The selection of the therapy - taking into account the pathophysiological mechanisms of pain - and the right timing can result in a successful analgesic outcome...

PURPOSE OF REVIEW: Recent literature focused on prescription opioids has neglected sex differences in use. Here, we evaluated the recent literature (since 2015) examining sex differences in prescription opioid use. RECENT FINDINGS: Between 2015 and 2016, our review found only eight articles addressing sex differences in prescription opioid use mostly opioid misuse in North America among individuals with chronic pain. Risk factors included depression, pain, and polydrug use...

Evidence has demonstrated that dynorphin (DYN) and the kappa opioid receptor (KOR) system contribute to various psychiatric disorders, including anxiety, depression, and addiction. More recently, this endogenous opioid system has received increased attention as a potential therapeutic target for treating alcohol use disorders. In this review, we provide an overview and synthesis of preclinical studies examining the influence of alcohol (ethanol) exposure on DYN/KOR expression and function, as well as studies examining the effects of DYN/KOR manipulation on ethanol's rewarding and aversive properties...

BACKGROUND: Endogenous opioids, including enkephalins, are fundamental regulators of pain. In inflammatory conditions, the local release of opioids by leukocytes at the inflammatory site inhibits nociceptor firing, thereby inducing analgesia. Accordingly, in chronic intestinal Th1/Th17-associated inflammation, enkephalins released by colitogenic CD4(+) T lymphocytes relieve inflammation-induced visceral pain. The present study aims to investigate whether mucosal T-cell-derived enkephalins also exhibit a potent anti-inflammatory activity as described for exogenous opioid drugs in Th1/Th17-associated colitis...

Studies in animal models suggest that sugar deprivation following excessive intake elicits some opioid-like withdrawal signs. In the present study, opioid-like effects of excessive sucrose intake were further characterized in C57BL/6 mice by comparing the effects of the opioid antagonist naloxone on food-reinforced responding before and during sucrose availability and, in parallel experiments, following chronic morphine administration. Results show that naloxone produced time-dependent and dose-dependent decreases in operant response rates after 4 weeks of excessive sucrose consumption, and that these effects were comparable with those produced by chronic morphine injections...

A fixed-dose combination tablet comprising the hepatitis C virus (HCV) NS5A inhibitor elbasvir and the HCV NS3/4A protease inhibitor grazoprevir (elbasvir/grazoprevir; Zepatier™) was recently approved for the treatment of chronic HCV genotype 1 and 4 infection in the EU and the USA. In phase III trials, 12 or 16 weeks of treatment with once-daily elbasvir/grazoprevir (fixed-dose tablet or as individual agents), taken with or without ribavirin, generally provided high rates of sustained virological response at 12 weeks (SVR12) in treatment-naive and -experienced adult patients with chronic HCV genotype 1a, 1b or 4 infection, including those with or without compensated cirrhosis, HIV co-infection, inherited blood disorders or chronic kidney disease or patients receiving opioid agonist therapy or of Japanese origin...

BACKGROUND: Childhood adversities and emotional dysregulation are connected with chronic pain, alexithymia, and depression. Longitudinal studies exploring the impact of their co-occurrence on the pain situation are rare. AIMS: The influence of alexithymia, depression, baseline pain situation, and treatment options on the course of chronic pain in a clinical sample was studied. METHODS: The baseline data was collected from chronic pain patients (n = 154) before their first pain clinic visit, and the follow-up data after 1 year by self-report questionnaires...

Low dose naltrexone (LDN) has been evaluated in several small studies for the treatment of inflammatory conditions. It is thought to work through modulation of inflammatory mediators and upregulation of endogenous opioid receptors. This may hypersensitize patients to exogenous opioids. Drug-drug interaction screening tools built into electronic health records and other services identify the interaction as risk of opioid withdrawal rather than hypersensitivity. We present a case of a drug-drug interaction in a patient who was receiving LDN treatment of multiple sclerosis...

REVIEW
Anitra C Carr, Cate McCall
The vitamin C deficiency disease scurvy is characterised by musculoskeletal pain and recent epidemiological evidence has indicated an association between suboptimal vitamin C status and spinal pain. Furthermore, accumulating evidence indicates that vitamin C administration can exhibit analgesic properties in some clinical conditions. The prevalence of hypovitaminosis C and vitamin C deficiency is high in various patient groups, such as surgical/trauma, infectious diseases and cancer patients. A number of recent clinical studies have shown that vitamin C administration to patients with chronic regional pain syndrome decreases their symptoms...
