ABSTRACT

Dorsal column (dcSCS) and dorsal root ganglion stimulation (DRG-S) complications are similar, typically related to placement and device failure. We present the first case of tinnitus after DRG-S implantation. The patient presented with complex regional pain syndrome (CRPS) type 2. After previous failed treatments, she had a lumbosacral DRG-S trial, which provided relief; however, she briefly noted ringing in her ears. After permanent implantation, she reported persistent, intolerable left-sided tinnitus. Tinnitus can be modulated by secondary somatosensory inputs to the cochlear nucleus from the dcSCS. Therefore, lumbosacral DRG-S stimulating distal sensory neurons leading to tinnitus is a feasible complication.

ABSTRACT

PURPOSE OF REVIEW: Pain medicine is rapidly expanding. The gap in treatment for patients with chronic pain in between traditional conservative therapy and major invasive surgery is closing. Neuromodulation is one therapeutic area that has continued to show promise for treatment of chronic pain. Our aim is to review updates in non-invasive neuromodulation (NIN) techniques as an adjunct for various chronic pain conditions. RECENT FINDINGS: Overall, the literature suggests that NIN techniques such as tCDS, TMS, TENS, tVNS, and HIFUS/LIFUS have utility in treating various types of chronic pain and have a promising future. There is a better understanding of the mechanistic basis for pain relief from NIN, as well as refinement in technology improving NIN therapy success. Future studies will need to focus on continuing to refine protocols for optimal benefit from NIN as well as implementing larger RCTs to improve the quality of data being generated in the field.

ABSTRACT

BACKGROUND: The COVID-19 pandemic resulted in a novel challenge for healthcare delivery and implementation in the United States (US) in 2020 and beyond. Telemedicine arose as a significant and effective medium for safe and efficacious physician-patient interactions. Prior to the COVID-19 pandemic, telemedicine while available, had infrequently been utilized in pain medicine practices due to difficulties with reimbursement, the learning curve associated with new technology usage, and the need for new logistical systems in place to implement telemedicine effectively. Given the unique constraints on the healthcare system during the COVID-19 pandemic, the ubiquitous utilization of telemedicine among pain medicine physicians increased, giving insight into potential future roles for the technology beyond the pandemic. OBJECTIVES: To survey and understand the state of implementation of telemedicine into pain medicine practices across practice settings and geographical areas; to identify potential barriers to the implementation of telemedicine in pain medicine practice; and to identify the likelihood of telemedicine continuing beyond the pandemic in pain medicine practice. STUDY DESIGN: Online questionnaire targeting Pain Medicine physicians in the US. Participants were asked questions related to the use of telemedicine during the first peak of the COVID-19 pandemic. SETTING: Online-based questionnaire distributed to academic and private practice pain medicine physicians nationally in the United States. METHODS: A 34 web-based questionnaires were distributed by the American Society of Regional Anesthesia and Pain Medicine and the Spine Intervention Society to all active members. Data were analyzed using SAS v9.4. RESULTS: Between December 3, 2020, and February 18, 2021, 164 participants accessed the survey with a response rate of 14.3%. Overall, academic physicians were more likely to implement telemedicine than private practice physicians. Telemedicine was also more frequently utilized for follow-up appointments rather than initial visits. LIMITATIONS: Although our n = 164, the overall low response rate of 14.3% warrants further investigation into the utilization of telemedicine throughout the COVID-19 pandemic. CONCLUSIONS: Telemedicine as an emerging technology for efficient communication played a key role in mitigating the adverse effects of the COVID -19 pandemic on chronic pain patients. The utilization of telemedicine remarkably increased after the start of the pandemic within 1 to 2 weeks. Overall, private hospital-based centers were significantly less likely to implement telemedicine than academic centers, possibly due to limited access to secure telemedicine platforms and high start-up costs. Telemedicine was used more frequently for follow-up visits than initial visit encounters at most centers. In spite of the unforeseen consequences to the healthcare system and chronic pain practices in the US from COVID-19, telehealth has emerged as a unique model of care for patients with chronic pain. Although it has flaws, telehealth has the ability to increase access to care beyond the end of the pandemic. Further identification of barriers to the use of telemedicine platforms in private practices should be addressed from a policy perspective to facilitate increased care access.

ABSTRACT

The management of patients on direct oral anticoagulants (DOACs) who require emergent cardiac surgery is slowly evolving. The introduction of andexanet alfa, a novel antidote for apixaban and rivaroxaban, added a specific reversal agent to our armamentarium, but its safety and efficacy are still being investigated. We report 2 patients on DOAC treatment who required emergency cardiac surgery. Both received perioperative andexanet alfa together with prothrombin complex concentrate (PCC) at some time during 6 hours before operative management. Heparin resistance was noted in each instance, and pump thrombosis developed in 1 case.

ABSTRACT

OBJECTIVE: This was a retrospective, cohort study investigating the efficacy and safety of continuous low-dose postoperative tranexamic acid (PTXA) on drain output and transfusion requirements following adult spinal deformity surgery. METHODS: One hundred forty-seven patients undergoing posterior instrumented thoracolumbar fusion of ≥ 3 vertebral levels at a single institution who received low-dose PTXA infusion (0.5-1 mg/kg/hr) for 24 hours were compared to 292 control patients who did not receive PTXA. The cohorts were propensity matched based on age, sex, American Society of Anesthesiologist physical status classification, body mass index, number of surgical levels, revision surgery, operative duration, and total intraoperative TXA dose (n = 106 in each group). Primary outcome was 72-hour postoperative drain output. Secondary outcomes were number of allogeneic blood transfusions. RESULTS: There was no significant difference in postoperative drain output in the PTXA group compared to control (660 ± 420 mL vs. 710 ± 490 mL, p = 0.46). The PTXA group received significantly more crystalloid (6,100 ± 3,100 mL vs. 4,600 ± 2,400 mL, p < 0.001) and red blood cell transfusions postoperatively (median [interquartile range]: 1 [0-2] units vs. 0 [0-1] units; incidence rate ratio [95% confidence interval], 1.6 [1.2-2.2]; p = 0.001). Rates of adverse events were comparable between groups. CONCLUSION: Continuous low-dose PTXA infusion was not associated with reduced drain output after spinal deformity surgery. No difference in thromboembolic incidence was observed. A prospective dose escalation study is warranted to investigate the efficacy of higher dose PTXA.

ABSTRACT

Inflammaging plays an important role in most age-related diseases. However, the mechanism of inflammaging is largely unknown, and therapeutic control of inflammaging is challenging. Human alpha-1 antitrypsin (hAAT) has immune-regulatory, anti-inflammatory, and cytoprotective properties as demonstrated in several disease models including type 1 diabetes, arthritis, lupus, osteoporosis, and stroke. To test the potential anti-inflammaging effect of hAAT, we generated transgenic Drosophila lines expressing hAAT. Surprisingly, the lifespan of hAAT-expressing lines was significantly longer than that of genetically matched controls. To understand the mechanism underlying the anti-aging effect of hAAT, we monitored the expression of aging-associated genes and found that aging-induced expressions of Relish (NF-ĸB orthologue) and Diptericin were significantly lower in hAAT lines than in control lines. RNA-seq analysis revealed that innate immunity genes regulated by NF-kB were significantly and specifically inhibited in hAAT transgenic Drosophila lines. To confirm this anti-inflammaging effect in human cells, we treated X-ray-induced senescence cells with hAAT and showed that hAAT treatment significantly decreased the expression and maturation of IL-6 and IL-8, two major factors of senescence-associated secretory phenotype. Consistent with results from Drosophila,RNA-seq analysis also showed that hAAT treatment significantly inhibited inflammation related genes and pathways. Together, our results demonstrated that hAAT significantly inhibited inflammaging in both Drosophila and human cell models. As hAAT is a FDA-approved drug with a confirmed safety profile, this novel therapeutic potential may make hAAT a promising candidate to combat aging and aging-related diseases.
