In this issue, you will find a paper by Vasović et al., entitled "Trigeminal neuropathic pain development and maintenance in rats are suppressed by a positive modulator of α6GABAA receptors" (D. Vasović et al., 2019). Loss of GABA-mediated inhibition within pain circuits is one of the mechanisms commonly invoked to explain allodynia and hyperalgesia following injury. Intrathecal administration of picrotoxin produces pain like signs. Positive allosteric modulators of GABAA receptors like benzodiazepines are known to produce analgesia although their main effects are sedative, hypnotic and anxiolytic and therefore their use as analgesics is curtailed (Schliessbach et al...

BACKGROUND: Complex Regional Pain Syndrome (CRPS) is much more prevalent in women than men but potential differences in clinical phenotype have not been thoroughly explored to date. Differences in the clinical presentation between sexes may point at new avenues for a more tailored management approach of CRPS. We therefore explored if in CRPS the patient's sex is associated with differences in clinical and psychological characteristics. METHODS: In this cross-sectional study of 698 CRPS patients (599 females) fulfilling the Budapest clinical or research criteria, CRPS signs and symptoms, CRPS severity, pain (average pain intensity in the previous week and McGill pain rating index), pain coping (Pain Coping Inventory), physical limitations (Radboud Skills Questionnaire (upper limb), Walking and Rising questionnaire (lower limb)), anxiety and depression (Hospital Anxiety and Depression scale) and kinesiophobia (Tampa scale for kinesiophobia) were evaluated...

INTRODUCTION: Pain which persists after thoracotomy is well recognized, and activation of the N-methyl-d-aspartate (NMDA) receptor could be a contributing factor. This study sought to establish whether ketamine given peri-operatively could reduce persistent post-surgical pain. TRIAL DESIGN: Double-blind, randomized, placebo-controlled trial comparing low-dose intravenous ketamine and saline placebo. METHODS: Seventy patients undergoing thoracotomy were randomized to receive either intravenous ketamine (0...

BACKGROUND: Transcutaneous electrical nerve stimulation (TENS) is a non-invasive treatment to relieve pain. Contralateral TENS (i.e., TENS administered to the contralateral side of a painful body part) is beneficial when TENS cannot be directly applied to pain site, such as in cases of trauma. Although TENS produces segmental analgesia in an ipsilateral limb, it has been unclear whether TENS produces higher analgesic effects in the contralateral segmental area. The aim of present study was to investigate the analgesic effects of TENS in contralateral segmental or extra-segmental areas on physiological and subjective pain outcomes, using a nociceptive flexion reflex (NFR) method...

BACKGROUND: Athletes who play contact sports are regularly exposed to pain, yet manage to perform complex tasks without significant decrement. Limited research has suggested that superior pain tolerance in contact athletes may be important in this context and this may be altered via experience of pain. Other psychological variables such as challenge states, pain bothersomeness and coping style may also influence skill execution during pain. METHODS: Forty experienced contact athletes (>3years experience), 40 novice contact athletes (<6months experience) and 40 non-contact athletes performed a motor task both in pain and without pain...

BACKGROUND: Primary dysmenorrhea (PDM), characterized as menstrual pain without pelvic pathology, is associated with pain-related negative mood and hormone fluctuations. Previous studies strongly supported the link between pain and negative mood in affected individuals; however, it remains largely unknown in patients with PDM. METHODS: We focused on the effects how spontaneous pain, negative mood and hormone levels played on the central nervous system in 34 PDM women and 33 matched healthy controls across their cycles (periovulatory phase and menstruation phase) by using T1-weighted and functional imaging...

Fibromyalgia represents a condition still controversial in its entity, pathophysiology, diagnosis and management. In a world where everybody is connected, and everybody is sharing their own image, fibromyalgia (FM) represents the emblematic pathology of misconnection and lack of specific biomarker. FM is an invisible experience with all normal tests and analyses, without any visible biomarker to exhibit to healthcare professionals, colleagues and relatives. In this context we propose to consider FM as a disease of misconnection at different levels: misconnection with society, misconnection with healthcare professionals, misconnection with pathophysiological concepts, misconnection between brain and body...

BACKGROUND: The Fear-Avoidance Model (FAM) is a leading theoretical paradigm for explaining persistent pain following musculoskeletal injury. The model suggests that as injuries heal, pain-related outcomes are increasingly determined by psychological, rather than physiological factors. Increasing literature, however, suggests that neurophysiological processes related to pain sensitivity also play an important role in chronicity. To date, there has been limited research that has specifically explored the role of pain sensitivity within the FAM...

GABAA receptors containing the α6 subunit are located in trigeminal ganglia, and their reduction by small interfering RNA increases inflammatory temporomandibular and myofascial pain in rats. We thus hypothesized that enhancing their activity may help in neuropathic syndromes originating from the trigeminal system. Here, we performed a detailed electrophysiological and pharmacokinetic analysis of two recently developed deuterated structurally similar pyrazoloquinolinone compounds. DK-I-56-1 at concentrations below 1 μM enhanced GABA currents at recombinant rat α6β3γ2, α6β3δ and α6β3 receptors whereas it was inactive at most GABAA receptor subtypes containing other α subunits...

BACKGROUND: Pain-related cues are evolutionarily primed to capture attention, although evidence of attentional biases towards pain-related information is mixed in healthy individuals. The present study explores whether healthy individuals show significantly different eye-movement behaviours when viewing real-world pain-related scenes compared to neutral scenes. The effect of manipulating via written information the threat value of the pain-related scenes on eye-movement behaviours was also assessed...

BACKGROUND: Placebo analgesia is explained by two learning processes: classical conditioning and observational learning. A third learning process, operant conditioning, has not previously been investigated as a mechanism of placebo effects. We aimed to induce placebo analgesia by operant conditioning. METHODS: Three groups of participants received electrocutaneous pain stimuli of the same intensity, preceded by either an orange or blue stimulus. In the conditioning phase of the study, participants from the experimental group were rewarded for low pain responses following one of the colour stimuli (placebo) and for high pain responses following the other colour stimuli (non-placebo)...

BACKGROUND: Estimation of a patient's pain may have a considerable impact on the level of care that patient receives. Many studies have shown that contextual factors may influence an observer's pain estimation. Here, we investigate the effect of an observer's impression of a person in pain and justification of his/her pain on the observer's pain estimation, tendency to help and perceived empathy. METHODS: Thirty healthy individuals (half females) read scenarios aimed to manipulate the reader's impression of characters who ultimately were fired from their work (four positive characters and four negative; half females)...

BACKGROUND: Psychosocial risk factors associated with chronic orofacial pain are amenable to self-management. However, current management involves invasive therapies which lack an evidence base and have the potential to cause iatrogenic harm. OBJECTIVES: To determine: 1) whether self-management is more effective than usual care in improving pain intensity and psychosocial well-being 2) optimal components of self-management interventions. DATABASES AND DATA TREATMENT: Cochrane Oral Health Group Trials Register, Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, PsycINFO, WHO International Clinical Trials Registry Platform and Clinical Trialsgov were searched...

Opioids have incredible power to make lives better, as well as destroy them. After the latest US opioid overuse crisis reported by the United Nations (UN) in 2017, several other countries started observing their own opioid consumption tendencies in order to better understand current practices, predict future changes, and protect their nations if necessary. The report presented by the UN showed the use of opioid in the US as being the highest of any country in the world, and more than fifty percent higher than Germany, the second country in the rank...

BACKGROUND: Complex Regional Pain Syndrome is a painful and disabling post-traumatic primary pain disorder. Acute and chronic CRPS are major clinical challenges. In Europe progress is hampered by significant heterogeneity in clinical practice. We sought to establish standards for the diagnosis and management of CPRS. METHODS: The European Pain Federation established a pan-European task force of experts in CRPS who followed a four-stage consensus challenge process to produce mandatory quality standards worded as grammatically imperative (must-do) statements...
