Local ozone (O2-O3) versus corticosteroid injection efficacy in plantar fasciitis treatment: a double-blinded RCT.
To compare the efficacy of local ozone injection versus corticosteroid in plantar fasciopathy treatment. ⋯ The present results showed no remarkable superiority between the two groups. In other words, although ozone injection showed a slower efficacy than methylprednisolone, it could be used in plantar fasciitis management as an appropriate alternative.

Altered gray matter volume in patients with herpes zoster and postherpetic neuralgia.
The aim of this study was to measure brain alterations in patients with herpes zoster (HZ) and postherpetic neuralgia (PHN) and compare their differences using a voxel-based morphometry (VBM) technique. ⋯ The VBM method revealed widespread GMV abnormalities in HZ and PHN patients. The brains of PHN patients have broader abnormalities in nonpain-related regions, suggesting the complexity of a central mechanism. When PHN patients were compared with HZ patients, the left cerebellar tonsil, culmen, and left lentiform nucleus corresponded to greater area under the curve, suggesting that abnormalities in these regions are risk factors for HZ patients' transformation to PHN.

TRPV1 channel contributes to remifentanil-induced postoperative hyperalgesia via regulation of NMDA receptor trafficking in dorsal root ganglion.
Remifentanil is widely used in general anesthesia due to its reliability and rapid onset. However, remifentanil-induced postoperative hyperalgesia might be a challenge nowadays. Accumulating evidence suggests that the transient receptor potential vanilloid 1 (TRPV1) was involved in the development of neuropathic pain and hyperalgesia. However, the contribution of TRPV1 in modulating remifentanil-induced postoperative hyperalgesia is still unknown. The aim of this study is the contribution of TRPV1 to the surface expression of N-methyl-d-aspartate (NMDA) receptors in remifentanil-induced postoperative hyperalgesia. ⋯ Our study demonstrates that TRPV1 receptors are involved in remifentanil-induced postoperative hyperalgesia. TRPV1 contributes to the persistence of remifentanil-induced postoperative hyperalgesia through the trafficking of NMDA receptors via the activation of CaMKII-PKC signaling pathways in DRG neurons.

Evaluation of postoperative analgesia in pediatric patients after hip surgery: lumbar plexus versus caudal epidural analgesia.
Background:There continues to be focus on the value of regional and neuraxial anesthetic techniques when combined with general anesthesia to improve postoperative analgesia. The reported advantages include decreased postoperative opioid requirements, decreased medication-related adverse effects, decreased hospital length of stay, and increased patient satisfaction. Orthopedic procedures of the hip may be amenable to such techniques as there is significant postoperative pain with the requirement for hospital admission and the administration of parenteral opioids. ⋯ Over the first 24 hrs after surgery, the median pain score in the LPB group was 5 (IQR: 1-6), compared to 3 (IQR: 0, 5) in the CEA group (p=0.014). Conclusion: These retrospective data suggest a modest postoperative benefit of CEA when compared to LPB following hip surgery in the pediatric population. Postoperative pain scores were lower in patients receiving CEA; however, no difference in the intraoperative or postoperative opioid requirements was noted between the two groups.

Therapeutic Efficacy and the Impact of the "Dose" Effect of Acupuncture to Treat Sciatica: A Randomized Controlled Pilot Study.
To investigate the required sample size for and feasibility of a full-scale randomized controlled trial examining the impact of the "dose" effect of acupuncture in treating sciatica. ⋯ Results of this pilot study indicate that acupuncture is safe and may effectively relieve symptoms and disability in patients with non-acute sciatica. MAL was as effective as MAH in treating sciatica. A subsequent trial with a larger sample size (estimated at n=96) is required to confirm whether patients with a high level of chronicity would benefit from MAH treatment.
