Background: No therapeutic intervention is universally accepted as the most effective treatment for adhesive capsulitis. An intra-articular corticosteroid injection (IAI) with a suprascapular nerve block (SSNB), a common treatment for this disease, is a safe and effective method for the resolution of pain and restoration of shoulder range of motion (ROM). Purpose: To compare the efficacy of combined SSNB and IAI with that of IAI alone in the treatment of adhesive capsulitis. Study Design: Cohort study; Level of evidence, 3. Methods: We performed a retrospective review of 102 patients with adhesive capsulitis who were treated at an outpatient clinic from July 2016 to January 2017. A combined SSNB with IAI was performed in 48 patients (SSNB + IAI group), and an IAI alone was performed in 54 patients (IAI group). Patients were assessed before the intervention and at 2 weeks and 2 months after the intervention. ROM and pain and function visual analog scales (PVAS and FVAS, respectively), the American Shoulder and Elbow Surgeons (ASES) score, the Korean Shoulder Scoring System (KSS), the Constant score, the Simple Shoulder Test (SST), and the Shoulder Pain and Disability Index (SPADI) were used for clinical assessments. PVAS, FVAS, and ASES scores at a minimum of 1 year after the intervention were assessed for 82 patients. Results: At the 2-month assessment, all parameters significantly improved in both the SSNB + IAI and IAI groups ( P < .05), however, improvements in forward flexion (FF) and abduction (ABD) between the 2-week and 2-month assessments were better in the SSNB + IAI group. At the 2-month assessment, improvements in the FVAS, ASES, SST, and SPADI scores and FF and ABD values were statistically significantly greater in the SSNB + IAI group compared with the IAI group. Improvements in FVAS and ASES scores were significantly greater in the SSNB + IAI group at a minimum of 1 year. Conclusion: Both a combined SSNB and IAI and an IAI alone significantly improved pain and functional outcomes in patients with adhesive capsulitis. The use of an SSNB with an IAI further increased treatment efficacy, as per the FVAS, ASES, SST, and SPADI scores and FF and ABD values. Patients who underwent SSNB combined with an IAI showed better improvements in the FVAS and ASES scores compared with IAI alone at a minimum of 1 year after the intervention. Therefore, an SSNB combined with an IAI may be a good treatment choice for adhesive capsulitis.
The placement of an anchoring stent appears to be a simple and effective method of preventing premature migration of FCSEMSs in patients with BBS. Appropriately powered studies are needed to confirm this finding.
Drugs are currently being developed to attenuate oxidative stress as a treatment for brain injuries. C-phycocyanin (C-Pc) is an antioxidant protein of green microalgae known to exert neuroprotective effects against oxidative brain injury. Astrocytes, which compose many portions of the brain, exert various functions to overcome oxidative stress; however, little is known about how C-Pc mediates the antioxidative effects of astrocytes. In this study, we revealed that C-Pc intranasal administration to the middle cerebral artery occlusion (MCAO) rats ensures neuroprotection of ischemic brain by reducing infarct size and improving behavioral deficits. C-Pc also enhanced viability and proliferation but attenuated apoptosis and reactive oxygen species (ROS) of oxidized astrocytes, without cytotoxicity to normal astrocytes and neurons. To elucidate how C-Pc leads astrocytes to enhance neuroprotection and repair of ischemia brain, we firstly developed 3D oxidized astrocyte model. C-Pc had astrocytes upregulate antioxidant enzymes such as SOD and catalase and neurotrophic factors BDNF and NGF, while alleviating inflammatory factors IL-6 and IL-1β and glial scar. Additionally, C-Pc improved viability of 3D oxidized neurons. In summary, C-Pc was concluded to activate oxidized astrocytes to protect and repair the ischemic brain with the combinatorial effects of improved antioxidative, neurotrophic, and anti-inflammatory mechanisms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
