RESUMO

OBJECTIVE: Surgical treatment for symptomatic Chiari I malformation involves surgical decompression of the craniovertebral junction. Given the proximity of critical brainstem structures, intraoperative neuromonitoring (IONM) is employed for safe decompression in some institutions. However, IONM adds time and cost to the operation, and the benefit to the patient has not been defined. Given the diversity in surgical practices, there is no evidence-based standard of care regarding when to use IONM and which modalities are most helpful. The purpose of this study was to review a single-surgeon experience with IONM in order to determine the sensitivity, specificity, and predictive values of various IONM modalities routinely used in pediatric Chiari I decompression; to examine the associations between patient, clinical, and radiographic characteristics and IONM alerts; and to obtain data regarding the usefulness of these modalities during the surgical process to improve patient outcomes. METHODS: A retrospective review was performed for 300 consecutive pediatric patients who underwent suboccipital craniectomy and C1 laminectomy for Chiari decompression performed by a single surgeon over a 15-year period. Clinical, radiographic, and IONM data were collected. Radiographic measurements of the skull base morphological abnormalities, including clival angle, Chamberlain's line, and Grabb-Oakes line, were compared between patients with and without true IONM signal changes. RESULTS: A total of 291 cases were included, with an age range of 6 months to 19 years. Among 291 cases, somatosensory evoked potentials (SSEPs) were monitored in 291, motor evoked potentials (MEPs) in 209, cranial nerve spontaneous electromyography (sEMG) in 290, and brainstem auditory evoked potentials (BAEPs) in 110. Sensitivity, specificity, positive predictive value, and negative predictive value, respectively, were as follows: 1.00, 1.00, 1.00, and 1.00 for SSEPs; 1.00, 0.99, 0.67, and 1.00 for MEPs; 0.00, 0.88, 0.00, and 1.00 for sEMG; and not appliable, 1.00, not applicable, and 1.00 for BAEPs. Six patients had true IONM signal changes. These patients had radiographic evidence of more severe concomitant craniocervical instability and basilar invagination, with steeper clival angles (124° vs 146°, p = 0.02) and larger Grabb-Oakes lines (10.1 mm vs 6.7 mm, p = 0.02), when compared with the patients without any true IONM changes. CONCLUSIONS: Intraoperative neuromonitoring may be best utilized for patients who show radiographic features of abnormal skull base morphology, defined as a clival angle < 135° or Grabb-Oakes line > 9 mm. When IONM is employed, SSEP and MEP monitoring are the most useful modalities.

RESUMO

OBJECTIVE: This study evaluated frontal behavioural symptoms, via the FrSBe self-report, in military personnel with and without a history of blast-related mild traumatic brain injury (mild TBI). METHODS: Prospective observational cohort study of combat-deployed service members leveraging 1-year and 5-year demographic and follow up clinical outcome data. RESULTS: The blast mild TBI group (n = 164) showed greater frontal behavioural symptoms, including clinically elevated apathy, disinhibition, and executive dysfunction, during a 5-year follow-up, compared to a group of combat-deployed controls (n = 107) without mild TBI history or history of blast exposure. We also explored changes inbehaviourall symptoms over a 4-year span, which showed clinically significant increases in disinhibition in the blast mild TBI group, whereas the control group did not show significant increases in symptoms over time. CONCLUSION: Our findings add to the growing evidence that a proportion of individuals who sustain mild TBI experience persistent behavioural symptoms. We also offer a demonstration of a novel use of the FrSBe as a tool for longitudinal symptom monitoring in a military mild TBI population.

RESUMO

BACKGROUND: A significant proportion of transfemoral cerebral angiography complications are related to the access site, with no clear consensus concerning the optimal closure technique. In this study, we examined the usefulness of a shortened closure protocol for transfemoral diagnostic cerebral angiography. METHODS: We performed a retrospective review of patients who underwent transfemoral (4Fr sheath) diagnostic cerebral angiography procedures at our institution. We included patients > 18 years old who underwent the shortened closure protocol to achieve hemostasis at the access site. The shortened protocol entailed the use of nonocclusive manual compression for 15 min followed by 2 h of bed rest, with additional 10-15 min of compression for new hematoma. We collected and analyzed the patients' demographics, use of antiplatelet and anticoagulation medications, sheath size, and others. RESULTS: The study cohort comprised 119 patients with a mean age was 54 years with (88%) females. Forty-one patients (34%) were on antiplatelet medications, with 12 (10%) on dual antiplatelet therapy (DAPT). Four patients (3%) (two on DAPT, one on Aspirin alone, and one was not on any antiplatelet medication) had access site hematoma that required additional compression. Subgroup analysis showed that within the DAPT, Aspirin alone, and no antiplatelet medications groups, (17%), (3%), and (1%) of patients developed access site hematoma, respectively. CONCLUSION: This pilot study demonstrates that our closure protocol for transfemoral angiograms is safe and effective. There was a trend toward higher access-site complications in patients on DAPT. Further studies are required to expand on and validate our results.

RESUMO

BACKGROUND: The provision of safe and timely surgical care is essential to global health care. Low- and middle-income countries have a disproportionate share of the global surgical disease burden and struggle to provide care with the given resources. Surgery cancellation worldwide occurs for many reasons, which are likely to differ between high-income and low-income settings. We sought to evaluate the proportion of elective surgery that is cancelled and the associated reasons for cancellation at a tertiary hospital in Malawi. METHODS: This was a retrospective review of a database maintained by the Department of Anesthesiology at Kamuzu Central Hospital in Lilongwe, Malawi. Data were available from August 2011 to January 2015 and included weekday records for the number of scheduled surgeries, the number of cancelled surgeries, and the reasons for cancellation. Descriptive statistics were performed. RESULTS: Of 10,730 scheduled surgeries, 4740 (44.2%) were cancelled. The most common reason for cancellation was infrastructural limitations (84.8%), including equipment shortages (50.9%) and time constraints (33.3%). Provider limitations accounted for 16.5% of cancellations, most often due to shortages of anaesthesia providers. Preoperative medical conditions contributed to 26.3% of cancellations. CONCLUSION: This study demonstrates a high case cancellation rate at a tertiary hospital in Malawi, attributable primarily to infrastructural limitations. These data provide evidence that investments in medical infrastructure and prevention of workforce brain drain are critical to surgical services in this region.

RESUMO

INTRODUCTION: Trauma is a major contributor to global morbidity and mortality, and injury to the central nervous system is the most common cause of death in these patients. While the provision of surgical services is being recognized as essential to global public health efforts, specialty areas such as neurosurgery remain overlooked. METHOD: This is a retrospective case review of patients with operable lesions, such as extra-axial hematomas and unstable depressed skull fractures that underwent neurosurgical interventions under local anesthesia. RESULTS: A total of 13 patients underwent neurosurgical intervention under local anesthesia. Two and three patients with burr hole decompression of epidural and subdural hematomas, respectively; seven patients had elevation of depressed skull fractures and lastly one patient had an aspiration of a brain abscess. All patients survived with and without residual neurological deficits. CONCLUSION: Access to resources and staff required to deliver general anesthesia is challenging in resource-poor settings. We have therefore begun performing emergent interventions under local anesthesia, with or without conscious sedation. While some patients had some minor residual weakness after the procedure, the degree of neurological deficit was improved from that observed before the procedure in all patients.

RESUMO

Global health research can transform clinical and surgical practice worldwide. Partnerships between US academic centers and hospitals in low- and middle-income counties can improve clinical care at the host institution hospital and give the visiting institution access to a large volume of valuable research data. Recognizing the value of these partnerships, the University of North Carolina (UNC) formed a partnership with Kamuzu Central Hospital (KCH) in Lilongwe, Malawi. The Department of Neurosurgery joined the partnership with KCH and designed a Head Trauma Surveillance Registry. The success of this registry depended on the development of methods to accurately collect head injury data at KCH. Since medical record documentation is often unreliable in this setting, data collection teams were implemented to capture data from head trauma patients on a 24-hours-a-day, 7-days-a-week basis. As data collection improved, pilot groups tested methods to collect new variables and the registry expanded. UNC provided onsite and remote oversight to strengthen the accuracy of the data. Data accuracy still remains a hurdle in global research. Data collection teams, oversight from UNC, pilot group testing, and meaningful collaboration with local physicians improved the accuracy of the head trauma registry. Overall, these methods helped create a more accurate epidemiological and outcomes-centered analysis of brain injury patients at KCH to date.

RESUMO

OBJECTIVE: Post-traumatic hydrocephalus (PTH) is a complication following traumatic brain injury (TBI). Early diagnosis and treatment are essential to improving outcomes. We report the incidence and risk factors of PTH in a large TBI population while considering death as a competing risk. METHODS: We conducted a retrospective cohort study on consecutive TBI patients with radiographic intracranial abnormalities admitted to our academic medical center from 2009 to 2015. We assessed patient demographics, perioperative data, and in-hospital data as risk factors for PTH using survival analysis with death as a competing risk. RESULTS: Among 7,473 patients, the overall incidence of PTH requiring shunt surgery was 0.94%. The adjusted cumulative incidence was 0.99%. The all-cause cumulative hazard for death was 32.6%, which was considered a competing risk during analysis. Craniectomy (HR 11.53, P < 0.001, 95% CI 5.57-223.85), venous sinus injury (HR 4.13, P = 0.01, 95% CI 1.53-11.16), and age ≤5 (P < 0.001) were significant risk factors for PTH. Glasgow Coma Score (GCS) > 13 was protective against shunt placement (HR 0.50, P = 0.04, 95% CI 0.26-0.97). Shunt surgery occurred after hospital discharge in 60% of patients. CONCLUSIONS: We describe the incidence and risk factors for PTH in a large traumatic brain injury (TBI) population. Most cases of PTH were diagnosed after hospital discharge, suggesting that close follow-up and multidisciplinary diagnostic vigilance for PTH are needed to prevent morbidity and disability.

RESUMO

BACKGROUND: Some patients with subdural hematoma (SDH) with acute extra-arachnoid lesions and without concomitant subarachnoid blood or contusions may present in similarly grave neurological condition compared with the general population of patients with SDH. However, these patients often make an impressive neurological recovery. This study compared neurological outcomes in patients with extra-arachnoid SDH with all other SDH patients. METHODS: We compared a prospective series of extra-arachnoid SDH patients without subarachnoid hemorrhage or other concomitant intracranial injury with a Transforming Research and Clinical Knowledge in TBI control group with SDH only. We performed inverse probability weighting for key characteristics and ordinal regression with and without controlling for midline shift comparing neurological outcomes (Extended Glasgow Outcome Scale score) at 2 weeks. We used the Corticosteroid Randomization After Significant Head Injury prognostic model to predict mortality based on age, Glasgow Coma Scale score, pupil reactivity, and major extracranial injury. RESULTS: Mean midline shift was significantly different between extra-arachnoid SDH and control groups (7.2 mm vs. 2.7 mm, P < 0.001). After weighting for group allocation and controlling for midline shift, extra-arachnoid SDH patients had 5.68 greater odds (P < 0.001) of a better 2-week Extended Glasgow Outcome Scale score than control patients. Mortality in the extra-arachnoid SDH group was less than predicted by the Corticosteroid Randomization After Significant Head Injury prognostic model (10% vs. 21% predicted). CONCLUSIONS: Patients with extra-arachnoid SDH have significantly better 2-week neurological outcomes and lower mortality than predicted by the Corticosteroid Randomization After Significant Head Injury model. Neurosurgeons should consider surgery for this patient subset even in cases of poor neurological examination, older age, and large hematoma with high degree of midline shift.

RESUMO

Complete traumatic cervical fracture-dislocation with spinal cord transection in children is a rare entity with no evidence-based guidelines on management. The authors reviewed the literature for pediatric spinal cord injury and present the case of a 3-year-old with traumatic cervical fracture-dislocation and spinal cord transection who presented as a cervical-6 complete spinal cord injury (ASIA A). His other organ systems injured included liver, spleen, bowel, and abdominal aortic injury. The patient underwent halo placement for preoperative reduction followed by open reduction and internal fixation with posterior segmental instrumented fusion. Intraoperatively, the patient had motor evoked potential signals present below the level of his injury. Early postoperative follow-up demonstrated that, although his leg function did not improve, he did demonstrate improvement in upper extremities. This is a rare case of complete cervical spinal cord transection in a pediatric patient. We elected to manage this challenging case with initial external reduction and orthosis with a halo vest followed by acute posterior cervical fusion. Despite a cervical-6 injury level on clinical exam, there was electrographic evidence of function below that level on intraoperative neuromonitoring. Postoperatively the patient has recovered some lost function.

RESUMO

Chondroblastoma is a rare bone tumor, most often found in epiphyseal plates of long bones. It has infrequently been reported in the skull, most often in the temporal bone. We present a case of chondroblastoma of the occipital bone in a pediatric patient presenting with a bony protuberance of the occiput and imaging consistent with obstructive hydrocephalus, which persisted even after removal of the obstructing tumor. Pathological examination demonstrated that this unusually placed tumor also lacked the classic genetic markers typically associated with chondroblastoma.

RESUMO

Body-Worn-Cameras (BWCs) are being introduced into Mental Health Inpatient Units. At present, minimal evidence surrounding their use in a mental health environment exists. This review examined research on the uses of BWCs in public sector services including healthcare, public transportation, and law enforcement. All eligible studies included a visible BWC, recording on a continuous loop as the main intervention. The evidence base presented high levels of bias, highly varied camera protocols, and heterogeneity of outcome measurements. This review found there is limited evidence for the efficacy of BWCs to control and manage violence within mental health inpatient wards. The technology has shown to be effective in reducing the number of public complaints in a law enforcement setting, but it is unclear how this is achieved. It appears there may be potential beneficial uses and unintended consequences of BWCs yet to be explored by mental health services.

RESUMO

OBJECTIVE: Cranioplasty is a technically simple procedure, although one with potentially high rates of complications. The ideal timing of cranioplasty should minimize the risk of complications, but research investigating cranioplasty timing and risk of complications has generated diverse findings. Previous studies have included mixed populations of patients undergoing cranioplasty following decompression for traumatic, vascular, and other cerebral insults, making results challenging to interpret. The objective of the current study was to examine rates of complications associated with cranioplasty, specifically for patients with traumatic brain injury (TBI) receiving this procedure at the authors' high-volume level 1 trauma center over a 25-year time period. METHODS: A single-institution retrospective review was conducted of patients undergoing cranioplasty after decompression for trauma. Patients were identified and clinical and demographic variables obtained from 2 neurotrauma databases. Patients were categorized into 3 groups based on timing of cranioplasty: early (≤ 90 days after craniectomy), intermediate (91-180 days after craniectomy), and late (> 180 days after craniectomy). In addition, a subgroup analysis of complications in patients with TBI associated with ultra-early cranioplasty (< 42 days, or 6 weeks, after craniectomy) was performed. RESULTS: Of 435 patients identified, 141 patients underwent early cranioplasty, 187 patients received intermediate cranioplasty, and 107 patients underwent late cranioplasty. A total of 54 patients underwent ultra-early cranioplasty. Among the total cohort, the mean rate of postoperative hydrocephalus was 2.8%, the rate of seizure was 4.6%, the rate of postoperative hematoma was 3.4%, and the rate of infection was 6.0%. The total complication rate for the entire population was 16.8%. There was no significant difference in complications between any of the 3 groups. No significant differences in postoperative complications were found comparing the ultra-early cranioplasty group with all other patients combined. CONCLUSIONS: In this cohort of patients with TBI, early cranioplasty, including ultra-early procedures, was not associated with higher rates of complications. Early cranioplasty may confer benefits such as shorter or fewer hospitalizations, decreased financial burden, and overall improved recovery, and should be considered based on patient-specific factors.

RESUMO

Objective: The pupillary light reflex (PLR) and the pupillary diameter over time (the PLR curve) is an important biomarker of neurological disease, especially in the diagnosis of traumatic brain injury (TBI). We investigated whether PLR curves generated by a novel smartphone pupillometer application could be easily and accurately interpreted to aid in the diagnosis of TBI. Methods: A total of 120 PLR curves from 42 healthy subjects and six patients with TBI were generated by PupilScreen. Eleven clinician raters, including one group of physicians and one group of neurocritical care nurses, classified 48 randomly selected normal and abnormal PLR curves without prior training or instruction. Rater accuracy, sensitivity, specificity, and interrater reliability were calculated. Results: Clinician raters demonstrated 93% accuracy, 94% sensitivity, 92% specificity, 92% positive predictive value, and 93% negative predictive value in identifying normal and abnormal PLR curves. There was high within-group reliability (k = 0.85) and high interrater reliability (K = 0.75). Conclusion: The PupilScreen smartphone application-based pupillometer produced PLR curves for clinical provider interpretation that led to accurate classification of normal and abnormal PLR data. Interrater reliability was greater than previous studies of manual pupillometry. This technology may be a good alternative to the use of subjective manual penlight pupillometry or digital pupillometry.

RESUMO

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To determine the rate of recurrent or adjacent-level stenosis requiring reoperation after single-door cervical laminoplasty for spondylotic myelopathy at our institution. SUMMARY OF BACKGROUND DATA: Adjacent-level stenosis requiring reoperation is a commonly evaluated condition for anterior or posterior arthrodesis, however, there are few studies that evaluate adjacent-level stenosis in the case of cervical laminoplasty. METHODS: Retrospective review of adults undergoing cervical laminoplasty for spondylotic myelopathy between January 2005 and May 2018 at our institution. Demographics, symptom duration, stenotic levels, preoperative and postoperative Medical Research Council motor, American Spinal Injury Association, modified Japanese Orthopaedic Association scores, and Nurick grade were obtained. Postoperative data included presence of C5 palsy, infection rate, alleviation or persistence of symptoms, and rate of recurrent or adjacent-level stenosis. RESULTS: A total of 102 patients underwent cervical laminoplasty; mean age was 56.7 years (±12.96). Most were men (n=76, 74.5%), with myelopathy (n=64, 63.4%), C4 (n=94, 93.1%), and C5 (n=92, 91.1%) cervical stenosis; mean symptom duration was 55 days (7 d to 2.8 y). Average follow-up was 6.4 months (±3.4). After surgery, there was statistically significant improvement in Nurick grade (3.1±2.2 vs. 2.7±2.4, P=0.002) and modified Japanese Orthopaedic Association score (11.4±3.7 vs. 13.9±3.6, P<0.001); American Spinal Injury Association scores also improved (P<0.001). Rate of postoperative C5 palsy was 7.8% (n=8); postoperative infection rate was 1.96% (n=2). Reoperation rate was 4.9% (n=5); reoperation for recurrent or adjacent-level stenosis was 1.96% (n=2). CONCLUSIONS: Recurrent or adjacent-level stenosis requiring reoperation after cervical laminoplasty is rare. Longitudinal studies are needed to verify correlation between motion preservation and incidence of adjacent or recurrent stenosis. LEVEL OF EVIDENCE: Level III-treatment benefits: nonrandomized controlled cohort/follow-up study.

RESUMO

BACKGROUND: Degenerative spine disease is common in athletes and can progress to requiring surgical intervention. Traditional open surgical techniques necessitate prolonged recovery time and time away from play. Newly developed endoscopic surgical techniques may promote faster healing and recovery, and increased return to play. The goal of this paper is to summarize the current evidence in return to play after spine surgery and to present our series of 3 athletes who underwent endoscopic spine surgery. METHODS: A complete search of all PubMed indexed articles pertaining to spine surgery in athletes was conducted. This was supplemented by a 3-patient case series of our own endoscopic spine experience in athletes. RESULTS: There are no current widely accepted guidelines for return to play after spinal surgery. The best evidence available cites a return to play of 81% at 5.2-8.7 months after traditional open and minimally invasive surgery, and endoscopic surgery produces an average 88% return to play rate at 3 months. CONCLUSIONS: Although return to play can vary widely, case-based evidence as well as biomechanical principles support endoscopic spine surgery as a viable surgical modality for the treatment of spinal pathologies in athletes.

RESUMO

Glycerol rhizotomy was originally described as an initial surgical treatment for trigeminal neuralgia after the failure of medical therapy. Here we describe its use as a salvage procedure, typically after failure of multiple other modalities including microvascular decompression, stereotactic radiosurgery, and/or other percutaneous procedures. Foramen ovale cannulation as a "salvage procedure" may be complicated by lack of cerebrospinal fluid (CSF) return despite adequate cannulation of the foramen ovale, making conventional fluoroscopic confirmation of adequate needle placement less certain. In this article, we describe the application of intraoperative CT, fused with high-resolution preoperative CT/MRI for neuronavigation to accurately cannulate the foramen ovale and Meckel's cave for glycerol rhizotomy. Intraoperative CT, again fused with high-resolution preoperative CT and MRI studies, was then used to confirm accurate trajectory through the foramen ovale and the adequate location of the needle tip in Meckel's cave before injecting glycerol. We present our initial experience with 14 patients who underwent glycerol rhizotomy by these techniques depending on intraoperative CT. It appears that intraoperative CT-guided neuronavigation provides a practical, reliable, and accurate route to the foramen ovale and aids in the confirmation of adequate needle placement even when there is a lack of CSF return. These methods may be especially useful for difficult cannulations typical in salvage procedures. In an era of feasible intraoperative guidance, with advanced stereotactic planning software allowing the fusion of intraoperative CT with high-resolution preoperative CT and MRI datasets, these techniques can be applied to foramen ovale cannulation for glycerol rhizotomy without major modification.

RESUMO

BACKGROUND: More than 90% of trauma mortality occurs in low- and middle-income countries, especially in sub-Saharan Africa. Head injury is the primary driver of trauma mortality in the prehospital and in-hospital setting. METHODS: An observational study was performed on patients presenting with traumatic brain injury (TBI) from October 2016 through May 2017 at Kamuzu Central Hospital, Malawi. Bivariate analysis and logistic regression were performed to determine the odds of favorable functional outcomes and mortality after controlling for significant covariates. RESULTS: Of the 356 patients with TBI, 72 (20.2%) were children <18 years of age. Males comprised 202 (87.1%) and 46 (63.9%) of the adult and pediatric cohorts, respectively. Motor vehicle crash was the leading etiology in adults and children. There was no significant difference between adult and pediatric Glasgow Coma Scale score on admission, 10.8 ± 3.9 versus 10.9 ± 3.5, respectively (P = 0.8). More adult (n = 76, 32.3%) than pediatric (n = 13, 18.1%) patients died. On multivariable analysis, pediatric patients were more likely to have a favorable outcome defined by a Glasgow Outcome Scale of good recovery or moderate disability (odds ratio 3.70, 95% confidence interval 1.22-11.17, P = 0.02) and were less likely to die after TBI (odds ratio 0.29, 95% confidence interval 0.09-0.93, P = 0.04). CONCLUSIONS: We show a survival advantage and better functional outcomes in children following TBI. This may be attributable to increased resiliency to TBI in children or the prioritization of children in a resource-poor environment. Investments in neurosurgical care following TBI are needed to improve outcomes.

RESUMO

Spinal cord injury (SCI) is relatively rare and affects an estimated 15-40 per 1 million people globally. All patients admitted from October 2016 to June 2017 at Kamuzu Central Hospital, Malawi with a spinal column injury were retrospectively studied. Out of 1442 patients, 46 had vertebral column injury, and half of these had neurological deficit. The most common mechanism of injury was road traffic crash (45.7%), and cervical SCIs were the most common (41.3%). The overall mortality was 15.2%, thus demonstrating devastating morbidity and mortality. Owing to the latter, and the relative lack of operative facilities, primary prevention remains the most effective way to attenuate the tragedy of SCIs.
