ReviewAcute pain management in dermatology: risk assessment and treatment.
Dermatologists perform many procedures that require acute pain control with local anesthesia and, in some cases, management of postoperative pain. Identifying early risk factors before a procedure can better prepare both the patient and provider anticipate acute postsurgical pain needs. Taking a multimodal, algorithmic approach to managing acute postsurgical pain in dermatology practice can effectively attenuate acute postsurgical paint and reduce patient opioid requirements.

To discuss the phenomenon of opioid induced hyperalgesia (OIH) and investigate the data and clinical recommendations available on this topic. ⋯ As more opioids are prescribed, especially to treat chronic nonmalignant pain, OIH becomes more of a relevant and significant issue. Although the exact mechanisms of OIH are not clearly understood further research is required to broaden and develop our knowledge of this topic.

EphB receptors and their ephrinB ligands are implicated in modulating spinal nociceptive information processing. Here, we investigated whether cyclooxygenase-2 (COX-2), acts as a downstream effector, participates in the modulation of spinal nociceptive information related to ephrinB/EphB signalling. ⋯ These results confirmed the important involvement of COX-2 in the modulation of spinal nociceptive information related to ephrinBs-EphBs signalling.

Multicenter StudyThe pelvic floor muscle hyperalgesia (PFMH) scoring system: a new classification tool to assess women with chronic pelvic pain: multicentre pilot study of validity and reliability.
The contribution of pelvic floor muscle tenderness to chronic pelvic pain (CPP) is well established in the literature. However pelvic floor muscle hyperalgesia (PFMH) is often missed during vaginal examination of women with CPP. To our knowledge criteria for diagnosing PFMH has not been established or validated so far. The aim of this study is to assess the validity and reliability of the PFMH scoring system. ⋯ The PFMH scoring system is a simple, reliable, valid and easy screening tool for in the assessment of women with CPP.

Opioid analgesia not only reduces inhalational anaesthetic requirements but may also induce delayed hyperalgesia, with potential effects on the minimum alveolar concentration (MAC) of inhalational anaesthetics. ⋯ Tramadol-induced hyperalgesia in the rat lasted for several weeks and was associated with an increase in the MAC of sevoflurane. Prior administration of ketamine blocked both phenomena.
