Delayed cerebral ischaemia (DCI) due to cerebral vasospasm (cVS) remains the foremost contributor to morbidity and mortality following aneurysmal subarachnoid haemorrhage (aSAH). Past efforts in preventing and treating DCI have failed to make any significant progress. To date, our most effective treatment involves the use of nimodipine, a calcium channel blocker. Recent studies have suggested that cilostazol, a platelet aggregation inhibitor, may prevent cVS. Thus far, no study has evaluated the effect of cilostazol plus nimodipine on the rate of DCI following aSAH.This is a multicentre, double-blinded, randomised, placebo-controlled superiority trial investigating the effect of cilostazol on DCI. Data concerning rates of DCI, symptomatic and radiographic vasospasm, length of intensive care unit stay, and long-term functional and quality-of-life (QoL) outcomes will be recorded. All data will be collected with the aim of demonstrating that the use of cilostazol plus nimodipine will safely decrease the incidence of DCI, and decrease the rates of both radiographic and symptomatic vasospasm with subsequent improvement in long-term functional and QoL outcomes when compared with nimodipine alone.Ethical approval was obtained from all participating hospitals by the Ascension Providence Hospital Institutional Review Board. The results of this study will be submitted for publication in peer-reviewed journals.NCT04148105.
Anterior cervical decompression and fusion (ACDF) procedures are common and neck scar appearance is important aesthetically. This study compared subcuticular suture closure with staple closure regarding the aesthetics of the neck incision scar.A single-blinded comparative prospective study with two cohorts involving one facility and multiple surgeons was done to study all consecutive patients who underwent one/two-level ACDF operations from 2015-2016. We excluded patients with corpectomies, postoperative wound infection, reoperations in the same admission, any previous ACDF operations, non-compliance in follow-up, and inability to give informed consent. We did single-layer skin stapling without platysma closure or subcuticular suture with platysma closure. Patients followed up between 1.5 and six months. We used the Stony Brook Scar Evaluation Scale (SBSES), range 0-5 with five being the best score. Digital images were taken in a standardized manner and saved in a secure database. A blinded plastic surgeon and a blinded neurosurgeon, not involved in the operation, evaluated the scars using SBSES. A priori sample size using a clinically significant difference of one was determined. Wilcoxon rank-sum test was used; a p-value <0.05 was considered statistically significant.We studied 93 staple and 66 suture closures. There is no significant difference between the groups regarding age, sex, the incidence of diabetes, smoking, obesity (body mass index (BMI) >30 kg/m2), chemotherapy or the length of the incision. There is no statistically significant difference regarding SBSES as evaluated by the plastic surgeon (staples vs. sutures, median 2 vs. 2, range 0-5, p = 0.32). There is a statistically significant difference as evaluated by the neurosurgeon (staples vs. sutures, median 4 vs. 3, range 0-5, p = 0.003). Post hoc power analysis was 0.90.Using the validated SBSES to assess the aesthetic outcome of ACDF scars, we demonstrated that staples and sutures provide equivalent aesthetic outcomes per plastic surgeon evaluation, and staple closure results in statistically significant better aesthetic outcomes per neurosurgeon evaluation.

Compression fractures are common among osteoporotic patients and can be a significant source of pain and disability. Patients who suffer a compression fracture at an instrumented level of a lumbar fusion are most often treated conservatively. Herein, we demonstrate a safe and effective treatment for a vertebral compression fracture (VCF) at a previous level with instrumented fusion and pedicle screw fixation. An 89-year-old female with a history of multiple osteoporotic compression fractures treated with previous kyphoplasties and a prior instrumented fusion at L4-L5 presented with debilitating lower back pain for one week. After failing conservative management, computed tomography (CT) and magnetic resonance imaging (MRI) study of the lumbar spine revealed an acute VCF of the previously instrumented L5 vertebral body. Under biplanar fluoroscopy, a balloon kyphoplasty was performed at the L5 vertebrae utilizing the Inflatable Vertebral Augmentation System (IVAS) from Stryker® (Kalamazoo, MI, USA). We were able to demonstrate that the treatment of an acute VCF with balloon kyphoplasty is feasible in patients who have a history of previous instrumentation with pedicle screws remaining at the fracture level.
Study Design. This was a single-institute retrospective study. Objective. To describe perioperative and postoperative complications in elderly who underwent multilevel minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) while identifying predictors of complications. Summary of Background Data. The number of elderly patients undergoing spinal fusion is rising. Spinal surgery in the elderly is considered high risk with high rates of complications. Perioperative and postoperative complications in elderly undergoing multilevel MIS TLIF is, however, not known. Methods. A retrospective analysis was performed on 467 consecutive patients who underwent multilevel MIS TLIF at a single institution from 2013 to 2017. Two cohorts, 70 years or older and 50 to 69 years old were analyzed. Multiple logistic regressions with minor and major complication rates as the dependent variables were performed to identify predictors of complication based on previously cited risk factors. A p- value of 0.008 or less was considered significant. Results. One hundred fifty-two elderly and 315 nonelderly patients underwent multilevel MIS TLIFs. The average age was 76.4 and 60.4 years for the elderly and nonelderly cohorts. We observed 13 major (8.44%) and 72 minor (47.4%) complications in the elderly. No difference was noted in complication rates between the cohorts, except for urinary tract infection ( P = .004) and urinary retention ( P = .014). There were no myocardial infarctions; hardware complications; visceral, vascular, and neural injuries; or death. Length of stay, comorbidity, and length of surgery were predictive of major and minor complications. Conclusion. Elderly may undergo multilevel MIS TLIF with comparable complication rates. Age was not a predictor of complications. Rather, attention should focus on evaluation of comorbidity and limiting operative times. Level of Evidence: 3
Abstract This study focuses on a subset of medical students who participated in an anatomy dissection program and undertook an additional self-directed learning (SDL) project investigating incidental findings of cadaveric pathology. The value of SDL activity is explored as a means of enhancing medical student education, particularly its student perceived value in preparing and developing them as future medical educators. It was assessed whether the project advanced student interest in medical education by analyzing their motivations for participation. The results of the study highlight the potential of SDL as an experiential learning opportunity for medical students and the role of anatomic pathology in connecting multiple domains of medical education.
Study Design. Retrospective review of prospectively collected data at a single institution. Objective. To compare perioperative and clinical outcomes in morbidly obese patients who underwent minimally invasive transforaminal lumbar interbody fusion (MiTLIF). Summary of Background Data. Obesity remains a serious public health concern. Obese patients who undergo lumbar fusion have historically thought to be at higher risk for complications and fare worse regarding quality-of-life outcomes. However, recent literature may demonstrate comparable risk and outcomes in obese patients. An increasing number of patients are categorized as morbidly obese (body mass index [BMI] ≥ 40 kg/m 2 ). Perioperative and patient-reported outcomes (PROs) are lacking in this patient population. Methods. The authors retrospectively reviewed a prospectively collected database of all morbidly obese and non-obese patients that underwent MiTLIF between 2015 and 2018 for degenerative conditions who had minimum 1-year follow-up for outcome assessment. An inverse propensity/probability of treatment weighting was utilized to create a synthetic weighted sample in which covariates were independent of obesity designation to adjust for imbalance between groups. Generalized estimating equations (GEE) was used to estimate the association of morbid obesity and complications and 1-year PROs. Results. A total of 292 patients were analyzed with 234 non-obese patients and 58 morbidly obese patients. Multivariate analysis failed to demonstrate any association between morbid obesity and achieving minimal clinically important difference (MCID) for Oswestry disability index (ODI), visual analog scale (VAS), or short form-12 (SF-12) physical component score. However, morbid obesity was associated with significant decrease in odds of achieving MCID for SF-12 mental component score ( P = 0.001). Increased surgery duration was significantly associated with morbid obesity ( P = 0.001). Morbid obesity exhibited no statistically significant association with postoperative complications, readmission, pseudarthrosis, or adjacent segment disease (ASD). Conclusion. Morbidly obese patients who undergo MiTLIF can achieve meaningful clinical improvement comparable to nonobese patients. Morbid obesity was associated with longer surgical times but was not associated with postoperative complications, readmission, or ASD. Level of Evidence: 3
