Review Practice Guideline
Standards for the management of cancer-related pain across Europe. A position paper from the EFIC Task Force on Cancer Pain.
Pain is a common symptom in patients who survive cancer and in those who live with progressive advanced disease. Evidence from meta-analyses suggests that pain remains poorly controlled for a large proportion of patients; barriers to good management include poor assessment of pain, inadequate support for patient self-management and late or inadequate access to strong opioid analgesia in those with advanced disease. ⋯ Pain affects up to 40% of cancer survivors and affects at least 66% of patients with advanced progressive disease, many of whom experience poor pain control. These 10 standards are aimed to improve cancer pain management, promote the quality of care of patients and reduce variation across Europe.

Primary dysmenorrhoea (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. ⋯ Our findings provide further evidence of amygdala-related abnormalities, which may be associated with pain-related affective distress and hormonal fluctuations in women with PDM, and complement the brain mechanism investigations for the pathophysiology of PDM.

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. ⋯ Athletes with even relatively small amounts of contact sport experience perform better during experimental pain than athletes who play non-contact sports. Experienced contact athletes had higher levels of direct coping and were more challenged and less threatened by pain than non-contact athletes.

γ-Aminobutyric acid type A (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. ⋯ Results obtained in two protocols of chronic constriction injury of the infraorbital nerve in rats dosed intraperitoneally with DK-I-56-1 during 14 days after surgery or with DK-I-56-1 or DK-I-87-1 during 14 days after trigeminal neuropathy were already established, demonstrated that DK-I-56-1 but not DK-I-87-1 significantly reduced the hypersensitivity response to von Frey filaments. SIGNIFICANCE: Neuropathic pain induced by trigeminal nerve damage is poorly controlled by current treatments. DK-I-56-1 that positively modulates α6 GABAA receptors is appropriate for repeated administration and thus may represent a novel treatment option against the development and maintenance of trigeminal neuropathic pain.
