Targeted Epidural Blood Patches Under Fluoroscopic Guidance For Incidental Durotomies Related To Spine Surgeries: A Case Series.
Incidental durotomies are usually managed conservatively. However, 1.8% of patients require surgical dural repair for CSF leak. There are limited data available regarding the use of epidural blood patches (EBP) for persistent CSF leaks secondary to incidental durotomies. This case series aims to evaluate the efficacy of targeted EBPs under fluoroscopic guidance in the treatment of incidental durotomies. ⋯ This case series demonstrated that targeted EBP can be an effective treatment for CSF leak from incidental durotomies. However, dural tears in the cervical region may be more difficult to treat. Larger scale studies are required to evaluate efficacy of EBP in the treatment of symptomatic incidental durotomies.

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.

C7 slope and its association with serum lipid levels and Modic changes in patients with cervical spondylotic myelopathy.
Background: Several studies have substituted the T1 slope (T1S) with the C7 slope (C7S) because the C7 endplate is clearer on radiographs. Further, abnormal serum lipid levels have been proven to be related with the development of disc degeneration. The aim of this study was to explore the relationship between C7S, serum lipid levels, cervical parameters related to cervical sagittal balance and Modic changes (MCs) in patients with multisegment cervical spondylotic myelopathy (CSM). ⋯ The correlation between HDL-C, LDL-C, ALB, GLB, Ca2+, C7S, T1S, MCs, NT, TIA, and C2-C7 SVA was statistically significant. Conclusion: Significant correlations were observed between MCs and TG (as well as other preoperative sagittal parameters), which may accelerate the development of degeneration of the cervical spine. Therefore, alcohol consumption, TG, and sagittal parameters, such as C7S, and T1S could be a promising candidate for the assessment of cervical sagittal balance and predicting neck pain.

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.

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.
