SUMMARY 1. Anthropogenic stressors may influence hosts and their pathogens directly or may alter host–pathogendynamics indirectly through interactions with other species. For example, in aquatic ecosystems, eutrophication may be associated with increased or decreased disease risk. Conversely, pathogens can influence community structure and function and are increasingly recognised as importan…

Abstract: Background: While many pain patients rely on pain-relieving treatments to manage their pain, painrelated research commonly quantifies pain status using validated questionnaires without taking into account that information. This will lead to an underestimate of the burden of pain in the community. To ensure a more accurate assessment of the prevalence and severity of pain, this study …
Abstract: Mechanisms of inflammatory and neuropathic pains have been elucidated and translated to patient care by the use of animal models of these pain states. Cancer pain has lagged behind since early animal models of cancer-induced bone pain were based on the systemic injection of carcinoma cells. This precluded systematic investigation of specific neuronal and pharmacological alterations t…
Abstract: Research has suggested that Solution-Focused Brief Therapy (SFBT) may be effective in facilitating meaningful change for those living with chronic pain. This study aimed to further this understanding through exploring the experiences of people living with chronic pain, who had attended an 8-weekSolution-focused pain management programme. The design of this study was conducted in con…

Abstract: Introduction: Phantom limb pain (PLP) is a painful sensation perceived in the missing limb after amputation. The underlying pathophysiology remains unclear. Until recently, only opioid analgesics have been proven to be effective in prospective studies. Anecdotally, patients with PLP employ self-help measures, sometimes including ‘wrapping up’ or rubbing their stump with alumini…
Abstract: Chronic trigeminal pain, with its severe related functional problems, is difficult to treat. Treatment is often empirically based on medications used for other chronic pain conditions. Systemic sodium channel and calcium channel blocking agents may cause a multitude of complications that are often poorly tolerated by the patient. Aim: The aim of this case report was to assess the …
Abstract: Background: In epidemiological studies, pain location is often collected by paper questionnaire using blank body manikins, onto which participants shade the location of their pain(s). However, it is unknown how reliable these will transfer to online questionnaires. The aim of the current study was to determine agreement between online- and paper-based completion of pain manikins. Me…

Summary points 1. Musculoskeletal problems are the commonest reason for medical discharge in all the British armed forces. By definition, these problems are chronic and resistant to treatment. 2. Pain is also common in veterans who have experienced severe injuries (polytrauma), often accompanied by post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI) orpost concussive syndr…
Abstract: Visceral pain is a highly complex entity whose experience is variable in health and disease. It can occur in patients with organic disease and also in those without any readily identifiable structural or biochemical abnormality such as in the functional gastrointestinal disorders (FGID). Despite considerable progress in our understanding of the culpable underlying mechanisms signifi…
Abstract: Many refugees in the developed world are survivors of torture and present with health needs without their traumatic experience being disclosed or identified. Chronic pain is a common problem, as are symptoms of post-traumatic stress disorder (PTSD), anxiety, depression, and other distress. Current circumstances, particularly poverty, uncertainty about asylum, separation from or loss …
Summary points •• Individual variability in pain perception and differences in the efficacy of analgesic drugs are complexphenomena and are partly genetically predetermined. •• Analgesics act in various ways on the peripheral and central pain pathways and are regarded as one ofthe most valuable but equally dangerous groups of medications. •• While pharmacokinetic properties of dr…
Abstract: Traumatic amputations remain one of the most emotionally disturbing wounds of conflict, as demonstrated by their frequent use in films to illustrate the horrors of war. Unfortunately, they remain common injuries, particularly following explosions, and, in addition, many survivors require primary amputation for unsalvageable injuries or to save their life. A third group, late amputat…
Abstract: Patients with chronic musculoskeletal pain are frequent users of healthcare. Whilst evidence suggests that a multidisciplinary pain management programme (PMP) approach is effective in reducing patients’ levels of distress and disability, there is little research examining the cost-effectiveness of such an approach. The present study sought to address this by examining the impact a …
Abstract: Endometriosis is an enigmatic disease and its fundamental cause is still unknown. Endometriosis associated pain syndrome is a common problem; it is underdiagnosed and patients suffering from the syndrome are rarely seen in specialist pain clinics. The correlation between the extent of the disease and pain is weak. Endometriosis-associated pain syndrome may be cyclical or persistent…

ABSTRACT: Benthic invertebrate communities were assessed after the December 2008 release of approximately 4.1 million m3 coal fly ash from a disposal dredge cell at the Tennessee Valley Authority (TVA) Kingston Fossil Plant on Watts Bar Reservoir in Roane County, Tennessee, USA. Released ash filled the adjacent embayments and the main channel of the Emory River, migrating into reaches of the E…
Abstract: The endocrine effects of opioids used for the management of persistent pain are poorly understood by clinicians and patients, and hormone levels are rarely measured. It is recognized that opioids exert this effect via the hypothalamic-pituitary-gonadal axis. Additional effects on adrenal hormones, weight, blood pressure and bone density may also occur. Symptoms and signs of sex hormo…
Abstract: It has been suggested that older persons are less likely to receive optimal care for pain, and a recent population study suggested that management of low back pain (LBP) in primary care differed with older age. Low back pain is the most commonly reported regional pain syndrome, and the objective of the current review was to determine the evidence base for managing LBP in older perso…
After suffering a stroke Mr Martin Stephen1 decided to write about his experience, narrating a moving yet entertaining story towards recovery. Interestingly, to achieve this very recovery he felt he needed to get out of hospital and cure himself. Reading about his hospital experience I thought that the care he received did not place him at its centre and was fragmented. It consisted of healthc…

In the patient with pain on opioid therapy, use the ‘4 Cs’ to diagnose addiction. 3. Screening and risk stratification of all patients considered for opioid therapy is a key element of ‘universal precautions’ in pain management. 4. There …
Abstract: Failed back surgery syndrome (FBSS) is a complex condition which can be very difficult to treat. In this article, we propose a pragmatic algorithm for the management of the syndrome. The management of this condition should include a comprehensive initial assessment to rule out treatable cause, pharmacological optimisation, psychological techniques and neuromodulation. There is good e…
Summary Points 1. Neuraxial opioids are considered for use in patients who have resistant intractable pain that fails to respond to other treatment options or pain that responds to analgesia but for which the doses required result in unacceptable side-effects. 2. Neuraxial opiods can be considered for both chronic non-malignant pain and chronic cancer related pain. 3. Effectiveness in chroni…
Summary points 1. The majority of people living with persistent pain will receive treatment for the pain from nonspecialists in pain management who may not have received the necessary training to deliver highquality care. 2. There is now a wide range of learning platforms and packages available, but these may struggle to reach beyond those with a specialist interest. Addressing this will requ…
