RESUMO

INTRODUCTION: Catastrophizing is associated with worse pain outcomes after various procedures suggesting its utility in predicting response. However, the stability of pain catastrophizing as a static predictor has been challenged. We assess, among patients undergoing steroid injections for chronic low back pain (cLBP), whether catastrophizing changes with the clinical response to pain interventions. METHODS: This prospective study enrolled patients undergoing fluoroscopic-guided injections for cLBP. Patients filled out Brief Pain Inventory (BPI) and Pain Catastrophizing Scale (PCS) at baseline and 1-month follow-up. We assessed the change in PCS scores from pre-injection to post-injection and examined its predictors. We also examined the correlation of various domains of BPI, such as pain severity and effect on Relationships, Enjoyment, and Mood (REM), with PCS scores at baseline and follow-up. RESULTS: 128 patients were enrolled. Mean (SD) PCS and pain severity scores at baseline were 22.38 (±13.58) and 5.56 (±1.82), respectively. Follow-up PCS and pain severity scores were 19.76 (±15.25) and 4.42 (±2.38), respectively. The change in PCS pre-injection to post-injection was not significant (p=0.12). Multiple regression models revealed baseline PCS and REM domain of BPI as the most important predictors of change in PCS after injection. Pain severity, activity-related pain, age, sex, insurance status, depression, prior surgery, opioid use, or prior interventions did not predict change in PCS score. In correlation analysis, change in PCS was moderately correlated with change in pain (r=0.38), but weakly correlated with baseline pain in all pain domains. CONCLUSIONS: PCS showed non-significant improvement following steroid injections; the study was not powered for this outcome. Follow-up PCS scores were predicted by the REM domain of BPI, rather than pain severity. Larger studies are needed to evaluate a statistically significant and clinically meaningful change in catastrophizing scores following pain interventions.

RESUMO

Extubation failure remains a challenge in the perioperative setting. The aim of this intervention was to decrease the rate of perioperative extubation failure through the utilization of an extubation checklist. A five-item evidence-based extubation readiness checklist was implemented at a level I trauma center on all patients who were electively extubated in the operating room (OR). Extubation failure rates before and after implementation of the checklist were compared. Of 26,867 trauma patients extubated in the OR after the intervention, 84 cases (0.31%) failed extubation in the immediate postoperative period. A significant and sustained decrease in extubation failure rate per case performed was observed between the pre- and post-checklist period (OR, 0.33; 95% CI, 0.19, 0.56; P < 0.001). Partial (vs full) checklist completion, higher ASA physical status score, advanced age, and longer case length were independently associated with increased odds of extubation failure in the postintervention period.

RESUMO

This article presents data on anesthesia cases filed with the Maryland Health Claims Alternative Dispute Office between 1994 and 2017, a publicly available resource that includes all anesthesia-related claims filed in Maryland, regardless of whether they were reported to any national claims repository. Analysis of anesthesia malpractice claims offers critical information that can both decrease legal liability and improve patient outcomes for those receiving anesthesia. A total of 276 claims were filed. Variables under investigation included venue, types of surgery, legal cause of action, trends, and outcomes. Types of anesthesia-related claims included the administration of general anesthesia (59.8%), monitored anesthesia care (14.9%), pain management (10.9%), epidural/spinal anesthesia (9%), nerve blocks (2.9%), and local anesthesia infiltration (2.6%). Most cases (39.5%) involved failure to adequately monitor the patient. Inadequate perioperative care was alleged as the cause of action in 68.8% of cases. Major adverse patient outcomes were death (38.8%), brain damage (21%), and permanent nerve damage (14.9%). Understanding the events that lead to legal action can assist anesthesia providers to focus on ways to improve their practice.

RESUMO

INTRODUCTION: The use of glucocorticoid as local anesthetic adjuvant in single-injection adductor canal block (ACB) is well-documented but its effects in the presence of an indwelling catheter is unclear. The purpose of this study was to determine the impacts of one-time perineural glucocorticoid injection on continuous adductor canal block in patients undergoing total knee arthroplasty. METHODS: A single center retrospective study of 95 patients undergoing unilateral total knee arthroplasty (TKA) was performed. Patients were divided into three groups based on adjuvant received through ACB before continuous catheter placement: a control group with no adjuvant (N = 41), a treatment group with dexamethasone (DEX) as adjuvant (N = 33) and another treatment group with DEX/ Methylprednisolone acetate (MPA) as adjuvant (N = 21). The primary outcome was the amount of ropivacaine administered via patient controlled ACB catheter. Secondary outcomes included numeric pain score, perioperative opioid usage, immediately postoperative prosthetic knee joint active range of motion (AROM), opioid usage at 6 weeks and 3 months, length of stay and discharge disposition. RESULTS: Patients in both treatment groups demonstrated a statistically significant decrease in the requirement of self-administered ropivacaine than the control group on postoperative day (POD) 1 (p<0.001) and POD 2 (p<0.001). There was no significant difference in opioid consumption and pain scores between either treatment group vs. control. Compared to control (66%), more home disposition was observed in the DEX (88%, p = 0.028) and DEX/MPA group (95%, p = 0.011). CONCLUSION: This study suggested that single dose perineural glucocorticoid injection with DEX or DEX/MPA significantly decreased the dose of local anesthetic ropivacaine infusion required through continuous ACB for TKA while maintaining comparable level of pain score and opioid consumption, and significantly more patients were discharged home.

RESUMO

OBJECTIVE: Collate available evidence and provide guidance on whether to delay steroid injections after receiving a vaccine, and whether to delay vaccination if a recent steroid injection has been administered, leaving formal recommendations to various national societies. METHODS: A literature search was performed to identify information pertinent to steroid administration and the subsequent downstream effects on vaccine efficacy. The search was initiated on December 20, 2020, and the terms used were (steroid OR cortisone OR dexamethasone) AND (vaccine). The studies were limited to articles in the English language. RESULTS: Six studies specifically addressed the effect of steroids on vaccine efficacy. Three of the 6 studies indicated that steroids could be used during the peri-vaccine period without significant suppression of the immune response. One study associated intra-articular steroid injections with an increased risk of developing influenza even when vaccinated. The remaining 2 studies had mixed findings. One study showed that patients who received dexamethasone, but not prednisolone were able to mount an immune response resulting in increased IgG. Another study showed that vaccine efficacy was maintained if patients were on continuous steroids or steroids after vaccination, but not if they stopped steroids prior to vaccination. CONCLUSIONS: Although there is no shared consensus in the studies reviewed, all but one study noted scenarios in which patients receiving steroids can still be successfully vaccinated.

RESUMO

Over the past four decades, there have been progressive changes in the epidemiology of traumatic spinal cord injury (tSCI). We assessed trends in demographic and injury-related variables in traumatic cervical spinal cord injury (tCSCI) patients over an 18-year period at a single Level I trauma center. We included all magnetic resonance imaging-confirmed tCSCI patients ≥15 years of age for years 2001-2018. Among 1420 patients, 78.3% were male with a mean age 51.5 years. Etiology included falls (46.9%), motor vehicle collisions (MVCs; 34.2%), and sports injuries (10.9%). Median American Spinal Injury Association (ASIA) Motor Score (AMS) was 44, complete tCSCI was noted in 29.6% of patients, fracture dislocations were noted in 44.7%, and median intramedullary lesion length (IMLL) was 30.8 mm (complete injuries 56.3 mm and incomplete injuries 27.4 mm). Over the study period, mean age and proportion of falls increased (p < 0.001) whereas proportion attributable to MVCs and sports injuries decreased (p < 0.001). Incomplete injuries, AMS, and the proportion of patients with no fracture dislocations increased whereas complete injuries decreased significantly. IMLL declined (p = 0.17) and proportion with hematomyelia did not change significantly. In adjusted regression models, increase in age and decreases in prevalence of MVC mechanism and complete injuries over time remained statistically significant. Changes in demographic and injury-related characteristics of tCSCI patients over time may help explain the observed improvement in outcomes. Further, improved clinical outcomes and drop in IMLL may reflect improvements in initial risk assessment and pre-hospital management, advances in healthcare delivery, and preventive measures including public education.

RESUMO

BACKGROUND: Intraoperative manipulation of the craniocervical junction with the Cervical Management Base Unit (CMBU) has been used as an adjunct for achieving optimal anatomic alignment during instrumented fusion procedures in a variety of disease settings. Here, we present our experience using the CMBU as a supplement to achieving a successful reduction and fixation of a reducible craniocervical subluxation with associated basilar impression/medullary compression in the setting of Grisel syndrome. CASE DESCRIPTION: Under fluoroscopy and neuromonitoring guidance, the elevator and axial translation mechanisms of the CMBU safely allowed for presurgical assessment of reducibility and facilitated complete reduction of the deformity with restitution of a normal atlantodental interval, spinolaminar line, and clivoaxial angle. Magnetic resonance imaging acquired 1 month after surgery and antibiotic therapy showed resolution of a large epidural abscess in the region of the dens and no evidence of residual neural impingement. Upright plain films at 9 months showed maintenance of the desired craniocervical alignment. CONCLUSIONS: Intraoperative manipulation of the craniocervical junction using the CMBU, when implemented under fluoroscopy and neuromonitoring, can safely facilitate an enduring anatomic correction of craniocervical deformity in the setting of Grisel syndrome. The dynamic utility of the CMBU for translation of the head and neck obviated the need to apply forces directly to hardware-bone interfaces, and its utility may extend to craniocervical disorders of other etiologies, especially those of a reducible nature and in the setting of poor bone quality and joint laxity.

RESUMO

BACKGROUND: Carotid endarterectomy (CEA) and carotid artery stenting (CAS) are well-established treatments that have been shown to decrease stroke recurrence in patients with underlying carotid artery disease. We assessed clinical outcome, safety, and restenosis rates for patients who underwent standardized CEA or CAS at our tertiary care center using patient selection criteria based on available scientific evidence. METHODS: Retrospective chart review of patients who underwent CEA or CAS between 2009 and 2016. RESULTS: In total, 314 cases (204 with CEA and 110 with CAS) were analyzed. Patients were predominantly white (84.4%), men (61.1%) with hypertension (86.9%) and hyperlipidemia (81.8%). Most patients (84.5%) had symptomatic carotid disease. No significant differences were observed in median postoperative National Institutes of Health Stroke Scale and modified Rankin scale (mRS) scores based on pretreatment symptomatic status or treatment modality (CEA vs. CAS). Most patients (85.9%) had favorable outcomes (mRS score 0-2) at a median follow-up of 11.7 months (interquartile range, 1.8-28.8). The perioperative complication rate was low (3.2%), and permanent neurologic deficit was seen in only 3 patients (1%). Restenosis was found in 7.3%, without significant difference between CEA and CAS at last follow-up. Restenosis was asymptomatic in most patients. CONCLUSIONS: Our findings in a real-world predominantly symptomatic cohort demonstrate that favorable patient outcomes and low restenosis and complication rates can be achieved with both CEA and CAS by the utilization of a consistent institutional patient selection and treatment process.

RESUMO

STUDY DESIGN: Systematic review. OBJECTIVES: Past research has demonstrated increased speed and severity of progression for spinal epidural abscesses (SEAs) of the thoracic level, specifically, when compared with SEAs of other spinal cord levels. Untreated, this infection can result in permanent neurological sequelae with eventual progression to death if inadequately managed. Despite the seriousness of this disease, no articles have focused on the presentation, diagnosis, and treatment of SEAs of the thoracic level. For this reason, specific focus on SEAs of the thoracic level occurred when researchers designed and implemented the following systematic review. METHODS: A query of Ovid-Medline and EMBASE, Cochrane Central, and additional review sources was conducted. Search criteria focused on articles specific to thoracic epidural abscesses. RESULTS: Twenty-five articles met inclusion criteria. The most commonly reported symptoms present on admission included back pain, paraparesis/paraplegia, fever, and loss of bowel/bladder control. Significant risk factors included diabetes, intravenous drug use, and advanced age (P = .001). Patients were most often treated surgically with either laminectomy, hemilaminectomy, or radical decompression with debridement. Patients who presented with neurological deficits and had delayed surgical intervention following a failed antibiotic course tended to do worse compared with their immediate surgical management counterparts (P < .005). CONCLUSIONS: For the first time researchers have focused specifically on SEAs of the thoracic level, as opposed to previously published general analysis of SEAs as a whole. Based on the results, investigators recommend early magnetic resonance imaging of the spine, laboratory workup (sedimentation rate/C-reactive protein, complete blood count), abscess culture followed by empiric antibiotics, and immediate surgical decompression when neurological deficits are present.

RESUMO

BACKGROUND: Subjective tinnitus is a hearing disorder in which a person perceives sound when no external sound is present. It can be acute or chronic. Because our current understanding of its pathology is incomplete, no effective cures have yet been established. Mouse models are useful for studying the pathophysiology of tinnitus as well as for developing therapeutic treatments. NEW METHOD: We have developed a new method for determining acute and chronic tinnitus in mice, called sound-based avoidance detection (SBAD). The SBAD method utilizes one paradigm to detect tinnitus and another paradigm to monitor possible confounding factors, such as motor impairment, loss of motivation, and deficits in learning and memory. RESULTS: The SBAD method has succeeded in monitoring both acute and chronic tinnitus in mice. Its detection ability is further validated by functional studies demonstrating an abnormal increase in neuronal activity in the inferior colliculus of mice that had previously been identified as having tinnitus by the SBAD method. COMPARISON WITH EXISTING METHODS: The SBAD method provides a new means by which investigators can detect tinnitus in a single mouse accurately and with more control over potential confounding factors than existing methods. CONCLUSION: This work establishes a new behavioral method for detecting tinnitus in mice. The detection outcome is consistent with functional validation. One key advantage of mouse models is they provide researchers the opportunity to utilize an extensive array of genetic tools. This new method could lead to a deeper understanding of the molecular pathways underlying tinnitus pathology.

RESUMO

OBJECTIVE: This review examined the diagnostic approach, surgical treatment, and outcomes of cervical sympathetic chain schwannomas (CSCS) to guide clinical decision making. DATA SOURCES: Medline, EMBASE, and Cochrane databases. REVIEW METHODS: A literature review from 1998 to 2013 identified 156 articles of which 51 representing 89 CSCS cases were evaluated in detail. Demographic, clinical, and outcomes data were extracted by 2 independent reviewers with high interrater reliability (κ = .79). Cases were mostly international (82%), predominantly from Asia (50%) and Europe (27%). CONCLUSIONS: On average, patients were 42.6 years old (SD = 13.3) and had a neck mass ranging between 2 to 4 cm (52.7%) or >4 cm (43.2%). Nearly 70% of cases were asymptomatic at presentation. Presurgical diagnosis relied on CT (63.4%), MRI (59.8%), or both (19.5%), supplemented by cytology (33.7%), which was nearly always inconclusive (96.7%). US-treated cases were significantly more likely to receive presurgical MRI than internationally treated cases but less likely to have cytology (P < .05). Presurgical diagnosis was challenging, with only 11% confirmatory accuracy postsurgically. Irrespective of mass size, extracapsular resection (ie, complete resection with nerve sacrifice) was the most frequently (87.6%) performed surgical procedure. Common postsurgical adverse events included Horner's syndrome (91.1%), first bite syndrome (21.1%), or both (15.7%), with higher prevalence when mass size was >4 cm. Adverse events persisted in 82.3% of cases at an average 30.0 months (SD = 30.1) follow-up time. IMPLICATIONS FOR PRACTICE: Given the typical CSCS patient is young and asymptomatic and the likelihood of persistent morbidity is high with standard surgical approaches, less invasive treatment options warrant consideration.
