Factors Associated With Same Day Discharge Post-Spinal Cord Stimulator Placement.

BACKGROUND: Spinal cord stimulator (SCS) surgeries, whether performed using the open or percutaneous approach, are becoming increasingly common for a range of neuropathic pain conditions, including post-laminectomy syndrome and complex regional pain syndrome. However, there is limited knowledge regarding the factors linked to same-day discharge patterns following SCS. OBJECTIVE: The purpose of this study was to identify factors associated with same-day discharge after SCS placement. The primary outcome was same-day discharge. STUDY DESIGN: Retrospective, cohort study using a nationwide database. METHODS: Inclusion criteria included patients who underwent percutaneous or open SCS from January 1, 2014 through December 31, 2021. Exclusion criteria included patients with missing data (n = 178) and those with SCS implants for unlisted indications (n = 1,817). A multivariable analysis was conducted on the outcome data and co-variates associated with same-day discharge after SCS. RESULTS: After applying inclusion and exclusion criteria, a total of 18,058 patients remained in the final data set, including 7,339 patients who underwent percutaneous SCS and 10,719 patients who underwent open SCS procedures. After analysis, factors associated with increased rates of same-day discharge after SCS included men (odds ratio [OR] 1.16; 95% CI, 1.09 -1.24;  P < 0.001), patients on Medicaid (OR 1.64; 95% CI, 0.1.34 - 2.01; P < 0.001), and hospitals in the US Midwest (OR 1.66; 95% CI, 1.45 - 1.90; P < 0.001) and hospitals in the US West (OR 1.32; 95% CI, 1.20 - 1.46; P < 0.001). Factors associated with decreased rates of same-day discharge after SCS included the open approach (OR 0.21; 95% CI, 0.19 - 0.23; P < 0.001), Hispanic ethnicity (OR 0.61; 95% CI, 0.54 - 0.69; P < 0.001) and increased age (OR 0.99; 95% CI, 0.98 - 0.99; P < 0.001). LIMITATIONS: Since our study is retrospective, the data are subject to various biases, including variable confounding, human error in data entry, and generalizability of the results. CONCLUSION: These results can be used to help determine hospital bed needs post-SCS surgery. Future research should focus on identifying the specific reasons certain demographic and geographic factors might influence same-day discharge rates. Our study provides important insights into the factors associated with same-day discharge rates post open and percutaneous SCS implant and highlights the need for patient-centered, evidence-based approaches to health care delivery.

Cannabis and Anxiety: A Critical Review.

Introduction: Cannabis has been reported to have both anxiogenic and anxiolytic effects. Habitual cannabis use has been associated with anxiety disorders (AD). The causal pathways and mechanisms underlying the association between cannabis use (CU)/cannabis use disorder (CUD) and anxiety remain unclear. We examined the literature via a systematic review to investigate the link between cannabis and anxiety. The hypotheses studied include causality, the common factor theory, and the self-medication hypothesis. Methods: Critical systematic review of published literature examining the relationship of CU/CUD to AD or state-anxiety, including case reports, literature reviews, observational studies, and preclinical and clinical studies. A systematic MEDline search was conducted of terms including: [anxiety], [anxiogenic], [anxiolytic], [PTSD], [OCD], [GAD], [cannabis], [marijuana], [tetrahydrocannabinol], [THC]. Results: While several case-control and cohort studies have reported no correlation between CU/CUD and AD or state anxiety (N = 5), other cross-sectional, and longitudinal studies report significant relationships (N = 20). Meta-analysis supports anxiety correlating with CU (N = 15 studies, OR = 1.24, 95% CI: 1.06-1.45, p = 0.006) or CUD (N = 13 studies, OR = 1.68, 95% CI: 1.23-2.31, p = 0.001). PATH analysis identifies the self-medication hypothesis (N = 8) as the model that best explains the association between CU/CUD and AD or state-anxiety. Despite the support of multiple large cohort studies, causal interpretations (N = 17) are less plausible, while the common factor theory (N = 5), stress-misattribution hypothesis, and reciprocal feedback theory lack substantial evidential support. Conclusion: The association between cannabis and anxiety is best explained by anxiety predisposing individuals toward CU as a method of self-medication. A causal relationship in which CU causes AD incidence is less likely despite multiple longitudinal studies suggesting so.

Long-Term Outcomes After Spinal Cord Stimulator Placement in Patients with Pre-procedural Active Opioid Use Versus Patients Who Were Opioid-Naïve.

BACKGROUND: Outcome optimization after the placement of a spinal cord stimulator (SCS) is critical. The objective of this study was to determine if an association existed between pre-procedural opioid use (compared to patients who were opioid-naïve) and postoperative long-term outcomes following SCS placement. OBJECTIVE: To examine the impact of preprocedural opioid use on long-term outcomes after SCS therapy. STUDY DESIGN: Cohort study utilizing a nationwide database. SETTING: Retrospective. METHODS: With the use of data from HCA Healthcare's national database, a retrospective cohort study was performed to analyze differences in outcomes between opioid-naïve patients and preoperative opioid users who underwent SCS placements. The primary outcome of interest was device explantation at 6 months and 12 months. Secondary outcome measurements included reoperations and readmissions at 6 months and 12 months, as well as operative complications. Multivariable logistic regression models were performed to analyze the association of preoperative opioid use with those outcomes. The odds ratio (OR), 95% confidence intervals (CI), and P values were reported for the independent variables. RESULTS: The final study population consisted of 13,893 patients who underwent SCS placements. In univariate analyses, patients who used opioids preoperatively had higher 6-month (3.6% vs. 2.6%) and one-year removal rates (3.6% vs. 2.8%) (all P < 0.009). On multivariable logistic regression, those using opioids preoperatively had higher odds of removal at 6 months (OR = 1.290, 95% CI 1.05-1.58, P = 0.01) and at one year (OR = 1.23, 95% CI 1.01-1.50, P = 0.04). There was no difference between patients requiring preoperative opioids and patients who were opioid-naive as far as the odds of 6- or 12-month readmissions were concerned. Compared to the opioid-naive group, patients requiring preoperative opioids had increased odds of reoperation at 6 months (OR = 1.2, 95% CI 1.02-1.40, P = 0.03). There were no differences in the odds of complications between both cohorts. LIMITATIONS: Opioid use in this study was defined as using opioids preoperatively in the 30 days leading up to surgery. CONCLUSION: Patients requiring preoperative opioids before SCS placements had increased odds of SCS explantation at 6 months and 12 months, as well as increased odds of reoperation at 6 months.

The Association of Psychiatric Comorbidities With Short-Term and Long-Term Outcomes Following Spinal Cord Stimulator Placement.

BACKGROUND: Outcomes after spinal cord stimulator (SCS) placement are affected by psychologic comorbidities. It is part of routine practice to do psychologic assessments prior to SCS trials to assess for the presence of maladaptive behavioral patterns. However, few studies have sought to quantify the effect of psychiatric comorbidities on complications, reoperation, and readmission rates. The purpose of this study was to assess the association of psychiatric comorbidities with postprocedural outcomes after SCS implantation. MATERIALS AND METHODS: Inclusion criteria included SCS placement between 2015 and 2020 (percutaneous approach or an open laminectomy-based approach) using Healthcare Corporation of America National Database. Data on psychiatric comorbidities present at the time of SCS implantation surgery were collected. Outcomes of interest included complication rates (defined as lead migration, fracture, malfunction, battery failure, postoperative pain, infection, dural puncture, or neurological injury), reoperation rates (defined as either revision or explant [ie, removal]), and readmission rates within 30-day and 1-year time after SCS implantation. We measured the association between psychiatric comorbidities and outcomes using multivariable regression and reported odds ratio (OR) and respective 95% confidence intervals. RESULTS: A total of 12,751 cases were included. The most common psychiatric comorbidities were major depressive disorder (16.1%) and anxiety disorder (13.4%). In unadjusted univariate analysis, patients with any psychiatric comorbidity had heightened rates of any complication (27.1% vs 19.4%), infection (5.9% vs 1.9%), lead displacement (2.2% vs 1.3%), surgical pain (2.1% vs 1.2%), explant (14.7% vs 8.8%), and readmission rates at one year (54.2% vs 33.8%) (all p < 0.001). In multivariable logistic regression, with each additional psychiatric comorbidity, a patient had increased odds of experiencing any complication (OR = 1.5, 95% CI = 1.36-1.57, p < 0.001), requiring a reoperation (OR = 1.5, 95% CI = 1.37-1.6, p < 0.001), and requiring readmission (OR = 1.7, 99% CI = 1.6-1.8, p < 0.001). CONCLUSIONS: The presence of psychiatric comorbidities was found to be associated with postoperative complication rates, reoperation, and readmission rates after SCS placement. Furthermore, each consecutive increase in psychiatric comorbidity burden was associated with increased odds of complications, reoperation, and readmission. Future studies might consider examining the role of presurgical mental health screening (ie, patient selection, psychologic testing) and treatment in optimizing outcomes for patients with psychiatric comorbidities.

Spinal Cord Stimulator (SCS) Placement: Examining Outcomes Between the Open and Percutaneous Approach.

BACKGROUND: Spinal cord stimulator (SCS) placement has been gaining traction as an approach to modulate pain levels for several different chronic pain conditions. This procedure can be performed via a percutaneous or open approach. Data regarding SCS complications are relatively limited. OBJECTIVE: The purpose of this study was to leverage a large national database to examine outcomes between the percutaneous and open SCS placement approaches. Outcomes in this study include length of stay (LOS), complication rates, reoperation rates, and 1-year readmission rates. MATERIALS AND METHODS: Inclusion criteria for the current study is SCS placement between 2015 and 2020, with receipt of an SCS using either a percutaneous approach or an open laminectomy based approach. Encounters included were limited to true SCS placement, such that trial placements were not included in the study. Univariate statistics and multivariable logistic regression was performed to compare outcomes between cohorts. RESULTS: Total SCS case volumes were 9935 between the percutaneous (n = 4477, 45.1%) and open (n = 5458, 54.9%) approach. Patients receiving the percutaneous approach were found to have a mean decrease in LOS of 9.91 hours when compared to those receiving the open approach. The percutaneous approach was significantly associated with the need for reoperation within one year compared to the open approach (odds ratio [OR]: 0.663, p < 0.001), as well as with the need for readmission within 30 days (51.2% vs 40.2%, OR: 0.759, p < 0.001). CONCLUSION: The open approach, when compared to the percutaneous approach, had a longer mean LOS, lower outpatient discharge rates, and higher odds of experiencing an operative complication in comparison to the percutaneous approach. The percutaneous approach had relatively increased odds of thirty-day readmission, although no significant difference in one-year readmission or removal was demonstrated.

Experience of Botulinum Toxin A Injections for Chronic Migraine Headaches in a Pediatric Chronic Pain Clinic.

OBJECTIVES: Prevalence of chronic migraine in children can reach 7.7%, causing decreased school performance, difficulty with extracurricular activities (including sports, theater, or music), and changes in sleep and mood. Many studies confirm that botulinum toxin type A injections effectively alleviate chronic migraines in adults; however, the literature regarding children is sparse. This study aims to analyze the safety and effectiveness of botulinum type A injections in a group of pediatric patients diagnosed with chronic migraines in a pediatric pain clinic. METHODS: In this retrospective (2013-2018) study, the effects of botulinum toxin type A injections were analyzed using data from 65 pediatric patients diagnosed with chronic migraines. The study group ranged from 11 to 18 years of age. A pediatric pain management physician administered the botulinum using the Phase 3 Research Evaluating Migraine Prophylaxis Therapy program protocol and followed the pain pattern. Dosages, tolerance, and side effects were measured. RESULTS: In this study, 74% of the patients tried more than 6 medications before the injections. There was a decrease in the visual analog scale score of 5.2 ± 2.2 points upon 6-week follow-up. The mean amount of medication used was 173.2 ± 35 units, and patients received an average of 2.8 ± 1.1 units/kg. Adverse events include one patient who developed dizziness and another who had low-grade fevers with enlarged cervical lymph nodes; both resolved within few minutes. CONCLUSIONS: This study supports the use of botulinum type A for chronic migraines in pediatric patients. Multicentered, randomized studies with larger population are needed to evaluate the long-term safety and efficacy of this therapy.

Submandibular Gland Injury With a Ball Bearing Gunshot Wound.

Submandibular gland injury is a rare occurrence that has been only documented in case reports. This is due to its protected location under the mandible, and only penetrating injuries to the floor of the mouth or trauma underneath the mandible can reach and damage it. While pediatric injuries due to non-powder firearms are decreasing yearly, 80.8% of the injuries were due to ball bearing (BB) guns. This case report explores the diagnosis and management of a 16-year-old girl who presented with a BB gunshot wound to the submandibular gland. The anatomy, imaging, and surgical management are detailed, and diagnosis guidelines and treatment options are analyzed and explained. This case highlights the importance of understanding the harm that non-powder firearms are capable of causing despite being perceived as toys.

Routine circumcision? The role of prepuce in syndactyly repair.

Circumcisions are among the most commonly performed procedures in the pediatric population, but the value of the preputial skin often goes unrecognized as a potential graft (Ehrlichman et al., 2018). We highlight three patients who underwent coordinated circumcision and use of the excised preputial skin as a graft for syndactyly repair. Syndactyly, a condition where fingers are fused together, is often repaired utilizing skin from the groin region, which can result in unwanted hair growth and subcutaneous fat growth. The utilization of the prepuce is a convenient alternative that may have fewer undesirable qualities.

Acute Colonic Pseudo-Obstruction After Ventriculoperitoneal Shunt Placement for Normal Pressure Hydrocephalus.

Ogilvie's syndrome is a rare postoperative condition commonly referred to as a "colonic pseudo-obstruction" due to the absence of mechanical obstruction. It should be a differential for patients over the age of 60 years who present with nausea, vomiting, and colonic dilatations on imaging. Ogilvie's syndrome following a ventriculoperitoneal (VP) shunt placement is an extremely rare entity with only one other adult patient reported in the English literature. In this case report, we explore the diagnosis and management of a 76-year-old patient who presented with abdominal pain and multiple bouts of bilious, non-bloody vomitus two days after a ventriculoperitoneal shunt. The ultimate diagnosis of Ogilvie's syndrome along with imaging and subsequent management is detailed, and diagnosis guidelines and treatment options for Ogilvie's syndrome are analyzed and explained. This case highlights the importance of keeping Ogilvie's syndrome on the list of differentials in a postoperative patient in all abdominal surgeries, even if they are minimally invasive.

Scrotal abscess after a perforated appendicitis.

Although perforated appendicitis in pediatric patients can result in a diverse array of complications, scrotal abscess is a rarely documented phenomenon. We present a case of acute scrotum after laparoscopic appendectomy. A retrospective review of prior literature on scrotal abscess secondary to perforated appendicitis was performed via PubMed to review the clinical presentation, etiology, type of treatment and outcome of pediatric patients. Patients without a patent processus vaginalis still require vigilant follow-up postoperatively to ensure timely intervention if scrotal pain develops during recovery.

Cardiac resynchronization therapy reduces T-wave alternans in patients with heart failure.

AIMS: T-wave alternans (TWA) represents myocardial instability. The present study was to determine the impact of cardiac resynchronization therapy (CRT) on TWA and left ventricular ejection fraction (LVEF) in heart failure patients. METHODS AND RESULTS: T-wave alternans was analysed using a spectral method in 27 CRT-ICD patients. Ambulatory device electrograms were collected and LVEF and New York Heart Association (NYHA) classification were assessed at baseline prior to CRT and 3 months following CRT. Patients were followed for 6 months to monitor cardiac events. Spectral TWA of device electrograms was measured during AAI and CRT pacing tests. Each pacing mode had the up-titration pacing rate from 90 to 105 b.p.m. with 90 s for each pacing rate. At baseline, 20 (76.9%) patients had TWA during AAI pacing tests and 13 (50%) during CRT pacing tests (P = 0.044 between two pacing modes). Following 3-month CRT, TWA was identified in 11 patients (45.8%) during AAI pacing tests (a 31.1% reduction from the baseline value, P = 0.023) and 7 patients (28%) during CRT pacing tests (a 22% reduction, P = 0.108). Six of seven patients who had cardiac events had TWA (three patients had arrhythmic events, two died of heart failure, one received heart transplant). Overall, LVEF improved from 27.3 ± 5.8 to 35.9 ± 10.5% (P < 0.001) and NYHA classification improved from 2.8 ± 0.6 to 1.6 ± 0.6 after 3-month CRT (P < 0.001). CONCLUSION: In heart failure patients who receive a CRT-ICD, CRT reduces TWA that is associated to cardiac events, suggesting that CRT promotes clinically significant reverse electrical and mechanical remodelling.
