There has been no previous prospective examination of the homogeneity of chronic non-cancer pain (CNCP) patients in risk factors for non-adherent opioid use. ⋯ Clusters of CNCP patients with distinct risk profiles for non-adherence exist. Each group was identified by at least one risk factor but the likelihood of non-adherent opioid use was higher in groups with particular clusters of multiple risk factors. Not all those with risk factors display non-adherence, emphasising the need for strategies to reduce risk for those patients displaying particular clusters of risks.

Low back pain is a disabling and common condition, whose etiology often remains unknown. A suggested, however rarely considered, cause is neuropathy of the medial branch of the superior cluneal nerves (mSCN)-either at the level of the originating roots or at the point where it crosses the iliac crest, where it is ensheathed by an osseo-ligamentous tunnel. Diagnosis and treatment have, to date, been restricted to clinical assessment and blind infiltration with local anesthetics. ⋯ We hereby confirm that it is possible to visualize the mSCN in the majority of anatomical specimens. The patients described may indicate a higher incidence of mSCN syndrome than has been recognized. mSCN syndrome should be considered in patients with low back pain of unknown origin, and HRUS may be able to facilitate nerve detection and US-guided nerve block.

A 75-year-old man, who was healthy, visited the hospital because of shooting pain and numbness in both lower limbs (right > left). The patient had an L4/5 moderate right foraminal stenosis and right subarticular disc protrusion and received a lumbar epidural block. ⋯ The patient expired 4 months later with respiratory failure due to motor neuron disease. This case suggests that any abnormal neurological symptoms that occur after an epidural block should be examined thoroughly via testing and consultations to identify the cause of the symptoms.

The following case series describes the treatment of neuropathic pain in post-surgical scars, using adipocytes and adipose-derived stem/progenitor cells (ASCs). Two cases are described in which patients underwent lipofilling to treat painful scars after cosmetic surgery. ⋯ We found a notable long-lasting reduction in the NRS values after the "modified" lipofilling treatment. The results are promising and reinforce earlier data on the positive effect of lipofilling and pain in scars.

Spinal Cord Stimulation for Complex Regional Pain Syndrome: A Case Study of a Pregnant Female.
Spinal cord stimulation (SCS) is a form of neuromodulation, used to treat chronic neuropathic pain refractory to conventional medical management. Spinal cord stimulators are treatment options when intractable chronic pain has not responded to more conventional treatment modalities. Currently, the use of SCS is contraindicated in pregnancy. Nevertheless, many SCS/neuromodulation recipients are women of child bearing age who may become pregnant. There are no published reports that focus on the possible side effects of SCS or neuromodulation therapy on human fertility, fetal development, pregnancy, delivery, or lactation. ⋯ Women of child bearing age who are recipients of SCS/neuromodulation implantation should be informed of the limited knowledge available regarding the impact of SCS/neuromodulation use during pregnancy. For current recipients, decisions about ongoing use during pregnancy should be an individual decision based on the potential risks and benefits.
