To conduct a network meta-analysis comparing all treatments for osteoarthritis (OA) pain in the Cochrane Library.

The aim of this review was to assess diagnostic and treatment challenges of adolescents with SI joint pain. We diagnosed 13 of the patients who were referred to our chronic pain clinic because of low back pain (30%) with SI joint pain based on provocative tests response. We performed SI joint steroid infiltration. Six patients (46%) felt better immediately after the procedure and 1 (8%) patient had a one-side only pain relief after a bilateral block. Four of these patients (31%) did not experience any further episode of pain during the follow-up and three patients reported recurring pain on average 2 months after the initial procedure. The 2nd procedure was successful in two patients and the third one experienced pain again 12 months later, requiring a third successful infiltration. Six patients (46%) experienced pain again within a few hours or days after the infiltration and their pain score were unchanged compared with what they had reported prior to the procedure. We were unable to place the needle within the joint under fluoroscopy in 1 patient; however, we were successful repeating the procedure under CT guidance. One patient experienced a motor and sensory block in the distribution of the sciatic nerve immediately after the procedure, which resolved within 24 and 48 hours, respectively. SI joint pain is a distinctive pathology that can be present in children and adolescents and is often overlooked by practitioners. Its diagnosis and management are challenging in this population as it is in adults. SI joint steroids injections may play a role in the management of these patients.

The aim of the present study was to investigate the analgesic effects of repetitive transcranial magnetic stimulation over the primary motor cortex (M1-rTMS) using different stimulation parameters to explore the optimal stimulus condition for treating neuropathic pain.

To investigate the role of osteoarthritis (OA) in the incidence of musculoskeletal, metabolic, cardiovascular, digestive, neuro-psychological, kidney and other comorbidities/adverse events after (i) incident non-steroidal anti-inflammatory drug (NSAID) initiation and (ii) NSAID discontinuation.

Theta burst stimulation (TBS) is often used in clinical practice and research protocols for adults with neuropsychiatric disorders. There are substantial knowledge gaps related to the application of TBS in children and adolescents. This systematic review examined the safety and tolerability of TBS in children and adolescents.

Spinal neuroinflammation plays a critical role in the genesis of neuropathic pain. Accumulating data suggest that abscisic acid (ABA), a phytohormone, regulates inflammatory processes in mammals. In this study, we found that reduction of the LANCL2 receptor protein but not the agonist ABA in the spinal cord is associated with the genesis of neuropathic pain. Systemic or intrathecal administration of ABA ameliorates the development and pre-existence of mechanical allodynia and heat hyperalgesia in animals with partial sciatic nerve ligation (pSNL). LANCL2 is expressed only in microglia in the spinal dorsal horn. Pre-emptive treatment with ABA attenuates activation of microglia and astrocytes, ERK activity, and TNF□ protein abundance in the dorsal horn in rats with pSNL. These are accompanied by restoration of spinal LANCL2 protein abundance. Spinal knockdown of LANCL2 gene with siRNA recapitulates the behavioral and spinal molecular changes induced by pSNL. Activation of spinal toll-like receptor 4 (TLR4) with lipopolysaccharide leads to activation of microglia, and over production of TNF□, which are concurrently accompanied by suppression of protein levels of LANCL2 and peroxisome proliferator activated-receptor γ. These changes are ameliorated when ABA is added with LPS. The anti-inflammatory effects induced by ABA do not requires Gi protein activity. Our study reveals that the ABA/LANCL2 system is a powerful endogenous system regulating spinal neuroinflammation and nociceptive processing, suggesting the potential utility of ABA as the management of neuropathic pain.
