Acute kidney injury (AKI) is characterized by the acute nature and the inability of kidneys to maintain fluid homeostasis as well as adequate electrolyte and acid-base balance, resulting in an accumulation of nitrogenous waste and elevation of serum blood urea nitrogen and creatinine values. Acute kidney injury may be a single isolated event, yet oftentimes, it results from an acute chronic kidney disease. It is critical to seek out the etiology of AKI and to promptly manage the underlying chronic kidney disease to prevent comorbidities and mortality that may ensue. We described a case of a 16-year-old adolescent girl with Down syndrome who presented with AKI and electrolyte aberrance.Abdominal and renal ultrasounds demonstrated a significantly dilated bladder as well as frank hydronephrosis and hydroureter bilaterally. Foley catheter was successful in relieving the obstruction and improving her renal function. However, a magnetic resonance imaging was pursued in light of her chronic constipation and back pain, and it revealed a structural defect (tethered cord) that underlies a chronic process that was highly likely contributory to her AKI. She was managed accordingly with a guarded result and required long-term and close monitoring.

Sinus pericranii (SP) are abnormal vascular connections between extracranial scalp venous channels and intracranial dural sinuses. This vascular abnormality rarely results in significant sequelae, but in select cases, it can be symptomatic. We describe the case of a 7-year-old girl with an SP who experienced intermittent visual, motor, and sensory symptoms not previously described in the literature. Her symptoms resolved after surgical treatment of the SP. We propose a mechanism for her symptoms and the rationale for the role of neurosurgical intervention along with a review of the literature.

BACKGROUND: Heparin induced thrombocytopenia Type II (HIT-II) is a dangerous thromboembolic complication of heparin therapy. The current literature on incidence and outcomes of HIT-II in aneurysmal subarachnoid hemorrhage (aSAH) patients remains sparse. OBJECTIVE: We report our institution's incidence and outcomes of HIT-II in aSAH patients. METHODS: We performed a retrospective cohort study at an academic medical center between June 2014 and July 2018. All patients had aSAH confirmed by digital subtraction angiography. Diagnosis of HIT-II was determined by positive results on both heparin PF4-platelet antibody ELISA (anti-PF4) and serotonin release assay (SRA). RESULTS: 204 patients met inclusion criteria. Seven patients (7/204, 3.5%) underwent laboratory testing, three of whom met clinical criteria. HIT-II incidence was confirmed in two of these seven patients (2/204, 0.98%), who had high BMI and T4 scores. CONCLUSION: Our institution's report of HIT-II incidence in aSAH patients is lower than previously reported in this population and more closely parallels HIT-II incidence in the general and surgical ICU setting. Widely-accepted American College of Chest Physicians (ACCP) clinical diagnostic criteria in conjunction with anti-PF4 and SRA testing is the gold standard of clinical diagnosis of HIT-II in aSAH patients.

Background: Atlantoaxial rotatory subluxation (AARS) is a rare injury of the C1/C2 junction. It is often associated with trauma in adults. Treatment may depend on the duration of symptoms and clinical presentation, but there is no consensus regarding the ideal management of these injuries. Our objective is to ascertain the prevalence of neurological deficit, complications, and outcomes of patients diagnosed with AARS undergoing cervical fusion (CF) versus those treated without CF. Methods: The 2016-2019 National Inpatient Sample (NIS) was queried using International Classification of Diseases, 10th revision (ICD-10) for adult patients with C1/C2 subluxation. Patients undergoing CF were defined through ICD-10 procedure codes. Baseline health and acute illness severity was calculated using the 11-point modified frailty index (mFI-11). Presenting characteristics, treatment complications, and outcomes were evaluated of CF vs. non-CF patients. Results: Of 990 adult patients with AARS, 720 were treated without CF and 270 were treated with CF. CF patients were more often myelopathic. Patients that had undergone CF treatment were negatively associated with having had extensive trauma. Patients undergoing CF experienced significantly longer length of stay (LOS), increased healthcare resource utilization, and decreased inpatient mortality. Sepsis had a negative association with patients that underwent CF treatment while pneumonia had a positive association. Conclusions: Adult patients undergoing CF for AARS demonstrated an increase in healthcare resource utilization but also a significant decrease in mortality. Extent of acute injury appears to have a strong influence on decision making for CF. Further study of decision making for treatment of this rare injury in adults is warranted.
RESUMO
INTRODUCTION: The safety and efficacy of intravenous thrombolysis (IVT) before endovascular thrombectomy (EVT) for large vessel occlusion stroke remains a highly contested and unanswered clinical question. We aim to characterize the clinical profile, complications, and discharge disposition of EVT patients treated with and without preceding IVT using a large, nationally-representative sample. METHODS: The National Inpatient Sample was queried from 2015 to 2018 to identify adult patients with anterior circulation stroke treated with EVT with and without preceding IVT. Multivariable logistic regression analysis and propensity-score matching were employed to assess adjusted associations with clinical endpoints and to address confounding by indication for IVT, respectively. RESULTS: Among 48,525 patients identified, 40.7% (n = 19,735) received IVT prior to EVT. On unadjusted analysis, patients treated with IVT bridging therapy experienced higher rates of intracranial hemorrhage (26% vs. 24%, p = 0.003) and routine discharge to home with or without services (33% vs. 27%, p < 0.001), a lower frequency of thromboembolic complications (3% vs. 5%, p < 0.001), and lower rates of extended hospital stays (eLOS) (20% vs. 24%, p < 0.001). Multivariable logistic regression analysis adjusting for demographic and baseline clinical characteristics demonstrated independent associations of IVT bridging therapy with intracranial hemorrhage (aOR 1.28, 95% CI 1.15, 1.43; p < 0.001), thromboembolic complications (aOR 0.66, 95% CI 0.53, 0.83; p < 0.001), routine discharge (aOR 1.27, 95% CI 1.15, 1.40; p < 0.001), and eLOS (aOR 0.76, 95% CI 0.68, 0.85; p < 0.001). Sensitivity testing confirmed these findings. CONCLUSION: Preceding IVT was associated with favorable functional outcomes following endovascular therapy. Prospective randomized clinical trials are warranted for further evaluation.

BACKGROUND: Delayed cerebral ischemia (DCI) represents a devastating complication of aneurysmal subarachnoid hemorrhage (aSAH) and is a significant predictor of morbidity and mortality. Recent studies have implicated inflammatory processes in the pathogenesis of DCI. METHODS: aSAH patient data were retrospectively obtained from the eICU Collaborative Research Database (eICU CRD). Multivariable logistic regression models and receiver operating characteristic (ROC) curve analyses were employed to assess the association between low serum albumin (< 3.4 g/dL) and clinical endpoints: DCI and in-hospital mortality. RESULTS: Among 276 aSAH patients included in the analysis, 35.5% (n=98) presented with low serum albumin levels and demonstrated a higher incidence of DCI (18.4% vs. 8.4%, OR=2.45, 95% CI 1.17, 5.10; p=0.017) and in-hospital mortality (27.6% vs. 16.3%, OR=1.95, 95% CI 1.08, 3.54; p=0.027) compared to patients with normal admission albumin values. In a multivariable model controlling for age and World Federation of Neurosurgical Societies grade, low serum albumin remained significantly associated with DCI (OR=2.52, 95% CI 1.18, 5.36; p=0.017), but not with in-hospital mortality. A combined model for prediction of DCI, encompassing known risk factors in addition to low serum albumin, achieved an area under the curve of 0.65 (sensitivity=0.55, specificity=0.75). CONCLUSIONS: Serum albumin, a routine and inexpensive laboratory measurement, can may potentially aid in the identification of patients with aSAH at risk for the development of DCI.
RESUMO
BACKGROUND: Traumatic spinal injury (TSI) can lead to severe morbidity and significant health care resource utilization. Intraoperative navigation (ION) systems have been shown to improve outcomes in some populations. However, controversy about the benefit of ION remains. To our knowledge, there is no large database analysis studying the outcomes of ION on TSI patients. Here we hope to compare complications and outcomes in patients with TSI undergoing spinal fusion of 3 or more levels with or without the use of ION. METHODS: The 2015-2019 National Surgical Quality Improvement Program (NSQIP) database was queried for cases of posterior spinal instrumentation of 3 or more levels. This population was then selected for postoperative diagnosis consistent with TSI. The effect of prolonged operative time was analyzed for all patients. Propensity score matching analysis was performed to create ION case and non-ION control groups. Baseline demographic characteristics, complications, and outcome data were collected and compared between ION and non-ION groups. RESULTS: A total of 1,034 patients were included in the propensity matched analysis. Among comorbidities, only obesity was significantly more likely in the non-ION group. There was no difference in case complexity between the two groups. ION was associated with higher incidence of prolonged operative time but was a negative independent predictor for sepsis. Prolonged operative time was a significant independent predictor for pulmonary embolism and requirement of transfusion in all patients. Discharge to home, readmission, and reoperation rates did not differ between TSI patients with or without ION. CONCLUSIONS: Use of ION during posterior spinal fusion of 3 or more levels in TSI patients is not associated with worse outcomes. Prolonged operative time, rather than ION, appears to have a higher influence on the rate of complications in this population. Evaluation of ION in the context of specific populations and pathology is warranted to optimize its use.
RESUMO
Kissing spines syndrome, also known as Baastrup's disease, is a common yet underdiagnosed disorder involving close approximation of adjacent spinous processes. These painful pseudoarticulations may be secondary to the compensatory mechanisms that result from sagittal imbalance. Conventional operative correction of sagittal balance includes a wide range of procedures from facetectomies to vertebral column resection. Resection of kissing spines for the operative management of sagittal imbalance is a treatment modality not extensively discussed in the literature but may offer improved patient outcomes with shorter operative times, lower risk, and reduced length of stay. A 67-year old male with a history of degenerative disk disease and scoliosis presented with neurogenic claudication and severe back pain that worsened with walking and improved with sitting. X-ray imaging of the lumbar spine revealed straightening of the normal lumbar lordotic curvature with mild rotoscoliosis. There was also evidence of retrolisthesis of L2 on L3 that worsened with flexion. The patient had Baastrup's disease at the L3-4 and L4, 5 levels that contributed to his reduced range of motion on extension imaging. Operative treatments including long-segment fusion with interbody cages to correct sagittal balance were considered with a discussion of possible debilitating and high-risk post-surgical outcomes. Instead, the patient underwent a simple decompression surgery involving laminectomies and resection of kissing spines to correct his sagittal imbalance. Postoperative follow-up imaging demonstrated significant improvement in sagittal balance, and the patient expressed relief of back and leg pain. Although underdiagnosed, consideration of kissing spines syndrome in the surgical correction of sagittal imbalance may offer an improvement over conventional operations. Our case presents a unique surgical perspective on the treatment of spinal stenosis with kissing spines with particular regard to correcting the sagittal imbalance, avoiding debilitating procedures, and providing better immediate postoperative outcomes.
RESUMO
BACKGROUND: Spondyloptosis involving complete subluxation of spinal vertebrae resulting in permanent spinal cord damage is rarely caused by high-force trauma. Rapid re-stabilization of the spine is crucial for maximizing chances of neural recovery and can significantly improve the patient's quality of life. In this case study, we describe the challenges associated with the surgical management of traumatic thoracic spondyloptosis, and propose a novel, safe, step-wise, spinal reduction method employing an inflatable beanbag. CASE DESCRIPTION: A 17-year-old male fell 25 feet from a tree, resulting in anterior spondyloptosis at the T11/12 level. He presented with para plegia and a T11 sensory level to pin below the umbilicus. Surgical management involved a posterior-anterior-posterior approach with initial posterior decompression, then T12 corpectomy and reconstruction and finally pedicle screw fixation. We utilized an inflatable beanbag to realign the spinal column in a stepwise fashion, thereby minimizing the risk of damage to the surrounding structures, including the thecal sac and great vessels. Postoperatively, the patient regained some sensory function below his injury level of T11 but remained plegic. X-ray imaging confirmed successful spinal fusion. CONCLUSION: Early spinal realignment and stabilization following spondyloptosis at the T11/T12 level resulted in some improvement in sensory function without resolution of motor plegia. Here, we described how to utilize a novel beanbag reduction method to safely achieve stepwise spinal realignment.
RESUMO
BACKGROUND: Myelomeningocele (MM) is the most common congenital anomaly to affect the nervous system and affects 1500-2000 newborn infants per year in the United States. It is accompanied by symptomatic hydrocephalus in approximately 70%-80% of patients. Different treatment strategies for hydrocephalus characteristically result in different effects on the size of the ventricles. OBJECTIVE: The objective of this systematic review was to determine whether persistent ventricular enlargement adversely impacts neurocognitive development in patients with MM. METHODS: The PubMed National Library of Medicine Medline database and Embase were queried using MeSH headings and keywords relevant to neurocognitive or intellectual development and ventricular size or morphology. Abstracts were reviewed by the authors to identify which studies met strict inclusion criteria. An evidence table was constructed that summarized the included studies and reflected the quality of evidence (Classes I-III) that each represented. A recommendation was made that is based on the quality of the evidence. RESULTS: An initial abstract review utilizing strict inclusion/exclusion criteria yielded 48 studies, 9 of which underwent full-text review. There is limited and conflicting Class III evidence from 2 studies. CONCLUSION: Currently, there is insufficient data to conclude that ventricular size and morphology impact neurocognitive development.The full guideline can be found at https://www.cns.org/guidelines/guidelines-spina-bifida-chapter-5.

BACKGROUND: The incidence of spina bifida (SB) is higher in the developing world as compared to the United States because of folic acid deficiency during pregnancy. Advances in technology have made prenatal repair of myelomeningocele (MM) possible. OBJECTIVE: The objective of this guideline was to determine if there is a difference in the rate of development of tethered cord syndrome (TCS) in infants who had prenatal closure compared to infants who had MM repair after birth. METHODS: The Guidelines Task Force developed search terms and strategies to search PubMed and Embase for the relevant literature published between 1966 and September 2016. Strict inclusion/exclusion criteria were used. Full text articles were reviewed and, when appropriate, included as evidence. RESULTS: A total of 261 abstracts were reviewed. Fifty-four full-text articles were selected for further analysis. Three studies met inclusion criteria. CONCLUSION: There was Class II evidence from 1 study and Class III evidence from another 2 studies demonstrating that TCS develops in infants with prenatal MM closure at an equal or higher rate than with postnatal closure. There was an increased risk of development of inclusion cysts in infants who underwent in utero closure. Continued surveillance for TCS and/or the development of inclusion cysts in children with prenatal and postnatal closure of MM is indicated (Level II). Differences between prenatal and postnatal repair with respect to the development of TCS and/or inclusion cysts should be considered alongside other relevant maternal and fetal outcomes when deciding upon a preferred method for MM closure.The full guideline can be found at https://www.cns.org/guidelines/guidelines-spina-bifida-chapter-6.

BACKGROUND: The incidence of spina bifida (SB) in the developing world is higher than in the United States because of malnutrition and folic acid deficiency during pregnancy. Advances in technology have made prenatal repair of myelomeningocele (MM) possible. OBJECTIVE: The objective of the guidelines are, (1) To create clinical recommendations for best practices, based on a systematic review and analysis of available literature, (2) to obtain multi-disciplinary endorsement of these guidelines from relevant organizations, and (3) to disseminate the educational content to physicians to improve the care of infants with MM. METHODS: The Guidelines Task Force developed search terms and strategies used to search PubMed and Embase for literature published between 1966 and September 2016. Strict inclusion/exclusion criteria were used to screen abstracts and to develop a list of relevant articles for full-text review. RESULTS: Guidelines authors aimed to systematically review the literature and make evidence based recommendations about the timing of closure after birth, hydrocephalus, the impact of prenatal closure, and the effect of prenatal closure on ambulation ability and tethered spinal cord. Evidence concerning persistent ventriculomegaly and cognitive impairment was also evaluated. Hundreds of abstracts were identified and reviewed for each of the 5 topics. A total of 14 studies met stringent inclusion criteria. CONCLUSION: Based on a comprehensive systematic review, a total of 5 clinical practice recommendations were developed, with 1 Level I, 2 Level II and 2 Level III recommendations.The full guideline can be found at https://www.cns.org/guidelines/guidelines-spina-bifida-chapter-1.

BACKGROUND: Myelomeningocele (MM) is a condition that is responsible for considerable morbidity in the pediatric population. A significant proportion of the morbidity related to MM is attributable to hydrocephalus and the surgical management thereof. Postnatal repair remains the most common form of treatment; however, increased rates of prenatal diagnosis, advances in fetal surgery, and a hypothesis that neural injury continues in utero until the MM defect is repaired have led to the development and evaluation of prenatal surgery as a means to improve outcomes in afflicted infants. OBJECTIVE: The objective of this guideline is to systematically evaluate the literature to determine whether there is a difference in the proportion of patients who develop shunt-dependent hydrocephalus in infants who underwent prenatal MM repair compared to infants who had postnatal repair. METHODS: The Guidelines Task Force developed search terms and strategies used to search PubMed and Embase for relevant literature published between 1966 and September 2016. Strict inclusion/exclusion criteria were used to screen abstracts and to develop a list of relevant articles for full-text review. Full-text articles were then reviewed, and when appropriate, included as evidence. RESULTS: A total of 87 abstracts were identified and reviewed by 3 independent reviewers. Thirty-nine full-text articles were selected for analysis. Three studies met selection criteria and were included in the evidence table. CONCLUSION: Class I evidence from 1 study and class III evidence from 2 studies suggest that, in comparison to postnatal repair, prenatal surgery for MM reduces the risk of developing shunt-dependent hydrocephalus. Therefore, prenatal repair of MM is recommended for those fetuses who meet specific criteria for prenatal surgery to reduce the risk of developing shunt-dependent hydrocephalus (level I). Differences between prenatal and postnatal repair with respect to the requirement for permanent cerebrospinal fluid diversion should be considered alongside other relevant maternal and fetal factors when deciding upon a preferred method of MM closure.

BACKGROUND: Myelomeningocele (MM) is an open neural tube defect treated by pediatric neurosurgeons with prenatal or postnatal closure. OBJECTIVE: The objective of this systematic review was to answer the question: What is the evidence for the effectiveness of prenatal vs postnatal closure of MM regarding short and long-term ambulatory status? Treatment recommendations were provided based on the available evidence. METHODS: The National Library of Medicine PubMed database and Embase were queried using MeSH headings and keywords relevant to ambulatory status after prenatal or postnatal closure of MM. Abstracts were reviewed to identify which studies met the inclusion criteria. An evidence table was assembled summarizing the studies and the quality of evidence (Classes I-III). Based on the quality of the literature, a recommendation was rendered (Level I, II, or III). RESULTS: One randomized controlled trial (Class II) and 3 retrospective cohort studies (Class III) were included as evidence. Initial ambulatory status depended on anatomic level of the neural tube defect. In the short term, prenatal closure may improve ambulatory status compared to postnatal closure. Spinal cord tethering or dermoid inclusion cyst has been associated with neurologic deterioration in infants closed in utero and after birth. Ambulation may cease in both groups over time. No long-term studies evaluated whether there is a difference in the ability to ambulate upon reaching adulthood. CONCLUSION: Prenatal closure of MM may improve ambulatory status in the short term (Level II). Spinal cord tethering in both groups caused deterioration in the ability to walk. Evaluation and treatment of spinal cord tethering may help maintain ambulatory status (Level III). No studies evaluate whether prenatal or postnatal repair provides improved ability to ambulate upon reaching adulthood.The full guideline can be found at https://www.cns.org/guidelines/guidelines-spina-bifida-chapter-3.

BACKGROUND: Appropriate timing for closure of myelomeningocele (MM) varies in the literature. Older studies present 48 h as the timeframe after which infection complication rates rise. OBJECTIVE: The objective of this guideline is to determine if closing the MM within 48 h decreases the risk of wound infection or ventriculitis. METHODS: The Guidelines Task Force developed search terms and strategies used to search PubMed and Embase for relevant literature published between 1966 and September 2016. Strict inclusion/exclusion criteria were used to screen abstracts and to develop a list of relevant articles for full-text review. Full text articles were then reviewed and when appropriate, included in the evidentiary table. The class of evidence was evaluated, discussed, and assigned to each study that met inclusion criteria. RESULTS: A total of 148 abstracts were identified and reviewed. A total of 31 articles were selected for full text analysis. Only 4 of these studies met inclusion criteria. CONCLUSION: There is insufficient evidence that operating within 48 h decreases risk of wound infection or ventriculitis in 1 Class III study. There is 1 Class III study that provides evidence of global increase in postoperative infection after 48 h, but is not specific to wound infection or ventriculitis. There is 1 Class III study that provides evidence if surgery is going to be delayed greater than 48 h, antibiotics should be given.The full guideline can be found at https://www.cns.org/guidelines/guidelines-spina-bifida-chapter-4.

BACKGROUND: Giant invasive spinal schwannomas (GISSs) comprise a rare, specific subtype of schwannomas that extend >2 spinal levels, erode vertebral bodies, and invade extraspinal tissues. Optimal surgical management of resulting spinal instability has yet to be determined, and overall there is limited published literature on GISS. We report an innovative method used to treat a rare case of lumbosacral GISS using a triangular frame reconstruction to reconnect the spinal column to the pelvis after tumor debulking. This method of using femur allograft in lieu of metal rods can promote stronger bony fusion of the construct. CASE DESCRIPTION: A 19-year-old woman presented with worsening lower back pain, which was due to a giant invasive spinal schwannoma that invaded the L4-S1 vertebral bodies and extended intrathecally from T10-S2, compromising the stability of her spine. The primary resection of the tumor was completed in 3 stages and was followed by a multilevel fusion involving a triangular construct made of femur allograft to reconnect the unstable spinal column with the pelvis. Maximal resection of the tumor was achieved with early rehabilitation. Pseudoarthrosis occurred, which was successfully fused after revision with the addition of an implanted bone stimulator. Seven years later, she remains in stable neurological condition. CONCLUSIONS: We recommend the use of femur allograft in triangular frame constructs for lumbosacral GISS to foster more stable, physiologic spinopelvic fusion.

The authors present a patient with a lipomyelomeningocele and worsening back pain due to recurrent tethered cord syndrome. Because of the increased risk and unlikely improvement in symptoms with repeated surgical untethering, she was offered an alternative treatment with a trial of dorsal spinal cord stimulation. She had an excellent response to the percutaneous trial, and a permanent implant was placed, with good initial results. The authors review her case as well as the treatment options, indications, and outcomes for recurrent tethered cord syndrome.

We present a novel salvage technique for pediatric subaxial cervical spine fusion in which lateral mass screw fixation was not possible due to anatomic constraints. The case presentation details a 4-year-old patient with C5-C6 flexion/distraction injury with bilateral jumped facets. Posterior cervical fixation was attempted; however, lateral mass fracture occurred during placement of screws. Using a wire-screw construct, an attempt was made to provide stable fixation. The patient was followed post-operatively for assessment of outcomes. After the patient had progressive kyphosis following initial closed reduction and external orthosis, internal reduction with fusion/fixation was performed. Lateral mass fracture occurred during placement of lateral mass screws. After placement of a sub-laminar wire-lateral mass screw construct, intra-operative evaluation determined stability. Post-operatively, the procedure resulted in stable fixation with evidence of bony fusion on follow-up. Pediatric subaxial cervical spine instrumentation provides rigid fixation however is technically difficult due to anatomic and instrumentation related constraints. In the presented patient, the wire-screw construct resulted in stable fixation and bony fusion on follow-up. A modified sublaminar wire-lateral mass screw construct is an example of a salvage technique that provides immediate stability in the event of instrumentation related lateral mass fracture.
