Title Endoscopic Transnasal Cryo-assisted Removal of an Orbital Cavernous Hemangioma: a Technical Note.
Date March 2012
Journal Minimally Invasive Neurosurgery : Min
Excerpt

The cryoprobe device is commonly used by orbital surgeons for the extraction of intraorbital lesions. Cryoprobes provide a safe mechanism to manipulate fluid-filled tumors. Such lesions can present in locations in which intraoperative neurosurgical assistance is essential. The authors describe a technique whereby removal of an orbital hemangioma was facilitated by the aid of an endoscopic, transnasal cryoprobe while standard microsurgical dissection was performed concurrently via a transconjunctival approach.

Title Hypoxia Activates the Notch Signaling Pathway in Cells of the Intervertebral Disc: Implications in Degenerative Disc Disease.
Date August 2011
Journal Arthritis and Rheumatism
Excerpt

To investigate whether hypoxia regulates Notch signaling, and whether Notch plays a role in intervertebral disc cell proliferation.

Title Comparison of Icd-9-based, Retrospective, and Prospective Assessments of Perioperative Complications: Assessment of Accuracy in Reporting.
Date January 2011
Journal Journal of Neurosurgery. Spine
Excerpt

large studies of ICD-9-based complication and hospital-acquired condition (HAC) chart reviews have not been validated through a comparison with prospective assessments of perioperative adverse event occurrence. Retrospective chart review, while generally assumed to underreport complication occurrence, has not been subjected to prospective study. It is unclear whether ICD-9-based population studies are more accurate than retrospective reviews or are perhaps equally susceptible to bias. To determine the validity of an ICD-9-based assessment of perioperative complications, the authors compared a prospective independent evaluation of such complications with ICD-9-based HAC data in a cohort of patients who underwent spine surgery. For further comparison, a separate retrospective review of the same cohort of patients was completed as well.

Title Outcomes After a Purely Endoscopic Transsphenoidal Resection of Growth Hormone-secreting Pituitary Adenomas.
Date December 2010
Journal Neurosurgical Focus
Excerpt

Using strict biochemical remission criteria, the authors assessed surgical outcomes after endoscopic transsphenoidal resection of growth hormone (GH)-secreting pituitary adenomas and identified preoperative factors that significantly influence the rate of remission.

Title Cerebral Cavernous Malformations As a Disease of Vascular Permeability: from Bench to Bedside with Caution.
Date November 2010
Journal Neurosurgical Focus
Excerpt

Tremendous insight into the molecular and genetic pathogenesis of cerebral cavernous malformations (CCMs) has been gained over the past 2 decades. This includes the identification of 3 distinct genes involved in familial CCMs. Still, a number of unanswered questions regarding the process from gene mutation to vascular malformation remain. It is becoming more evident that the disruption of interendothelial junctions and ensuing vascular hyperpermeability play a principal role. The purpose of this review is to summarize the current understanding of CCM genes, associated proteins, and functional pathways. Promising molecular and genetic therapies targeted at identified molecular aberrations are discussed as well.

Title Emerging Clinical Imaging Techniques for Cerebral Cavernous Malformations: a Systematic Review.
Date November 2010
Journal Neurosurgical Focus
Excerpt

Cerebral cavernous malformations (CCMs) are divided into sporadic and familial forms. For clinical imaging, T2-weighted gradient-echo sequences have been shown to be more sensitive than conventional sequences. Recently more advanced imaging techniques such as high-field and susceptibility-weighted MR imaging have been employed for the evaluation of CCMs. Furthermore, diffusion tensor imaging and functional MR imaging have been applied to the preoperative and intraoperative management of these lesions. In this paper, the authors attempt to provide a concise review of the emerging imaging methods used in the clinical diagnosis and treatment of CCMs.

Title Early Complications Related to Approach in Thoracic and Lumbar Spine Surgery: a Single Center Prospective Study.
Date October 2010
Journal World Neurosurgery
Excerpt

Thoracic and lumbar spine surgical procedures are performed for a variety of pathologies. The literature consists of multiple retrospective reviews examining complication prevalence with the surgical treatment of these disorders. However, there is limited direct examination of perioperative complications through a prospective approach. Of the prospective assessments, the majority focuses on specific surgical procedures or provides a limited assessment of certain spinal implants. Prospective assessments of complication incidence in broad patient populations are limited. This article analyzes a prospectively collected database of patients who underwent a thoracic and/or lumbar spine surgery at a large tertiary care center and the effect of surgical approach (anterior or posterior) on the incidence of early complications.

Title Obesity and Spine Surgery: Reassessment Based on a Prospective Evaluation of Perioperative Complications in Elective Degenerative Thoracolumbar Procedures.
Date October 2010
Journal The Spine Journal : Official Journal of the North American Spine Society
Excerpt

The correlation between obesity and incidence of complications in spine surgery is unclear, with some reports suggesting linear relationships between body mass index (BMI) and complication incidence and others noting no relationship.

Title Early Complications in Spine Surgery and Relation to Preoperative Diagnosis: a Single-center Prospective Study.
Date September 2010
Journal Journal of Neurosurgery. Spine
Excerpt

The reported incidence of complications in spine surgery varies widely. Variable study methodologies may open differing avenues for potential bias, and unclear definitions of perioperative complication make analysis of the literature challenging. Although numerous studies have examined the morbidity associated with specific procedures or diagnoses, no prospective analysis has evaluated the impact of preoperative diagnosis on overall early morbidity in spine surgery. To accurately assess perioperative morbidity in patients undergoing spine surgery, a prospective analysis of all patients who underwent spine surgery by the neurosurgical service at a large tertiary care center over a 6-month period was conducted. The correlation between preoperative diagnosis and the incidence of postoperative complications was assessed.

Title Deep Brain Stimulation in the Management of Disorders of Consciousness: a Review of Physiology, Previous Reports, and Ethical Considerations.
Date September 2010
Journal Neurosurgical Focus
Excerpt

Patients suffering from disorders of consciousness constitute a population that exists largely outside of the daily practice patterns of neurosurgeons. Historically, treatment has focused on nursing and custodial issues with limited neurosurgical intervention. Recently, however, deep brain stimulation has been explored to restore cognitive and physical function to patients in minimally conscious states. In this article, the authors characterize the physiological mechanisms for the use of deep brain stimulation in persistently vegetative and minimally conscious patients, review published cases and associated ethical concerns, and discuss future directions of this technology.

Title Complications in Spine Surgery.
Date August 2010
Journal Journal of Neurosurgery. Spine
Excerpt

The overall incidence of complications or adverse events in spinal surgery is unknown. Both prospective and retrospective analyses have been performed, but the results have not been critically assessed. Procedures for different regions of the spine (cervical and thoracolumbar) and the incidence of complications for each have been reported but not compared. Authors of previous reports have concentrated on complications in terms of their incidence relevant to healthcare providers: medical versus surgical etiology and the relevance of perioperative complications to perioperative events. Few authors have assessed complication incidence from the patient's perspective. In this report the authors summarize the spine surgery complications literature and address the effect of study design on reported complication incidence.

Title Endocrinological and Ophthalmological Consequences of an Initial Endonasal Endoscopic Approach for Resection of Craniopharyngiomas.
Date July 2010
Journal Neurosurgical Focus
Excerpt

The expanded endoscopic approach to craniopharyngiomas has recently been described in several small case series. The authors present their experience with this technique and review the available literature.

Title Adult Scoliosis Surgery Outcomes: a Systematic Review.
Date May 2010
Journal Neurosurgical Focus
Excerpt

Appreciation of the optimal management of skeletally mature patients with spinal deformities requires understanding of the natural history of the disease relative to expected outcomes of surgical intervention. Appropriate outcome measures are necessary to define the surgical treatment. Unfortunately, the literature lacks prospective randomized data. The majority of published series report outcomes of a particular surgical approach, procedure, or surgeon. The purpose of the current study was to systematically review the present spine deformity literature and assess the available data on clinical and radiographic outcome measurements.

Title Traumatic Spondyloptosis of the Thoracolumbar Spine.
Date September 2008
Journal Journal of Neurosurgery. Spine
Excerpt

OBJECT: Traumatic Grade V thoracolumbar spondylolisthesis, or traumatic spondyloptosis (severe translation injuries), are uncommon spinal injuries. To the best of the authors' knowledge, this article represents the first reported case series of these unique spinal lesions. METHODS: The authors undertook a retrospective review of a tertiary care regional spinal cord injury patient population treated over a 10-year period (1997-2007). They analyzed data regarding age, sex, mechanism of injury, neurological status, and treatment. RESULTS: Five patients were identified (3 men and 2 women) with ages ranging from 17 to 44 years. All patients had sustained high-energy closed spinal injuries: 3 motor vehicle accidents, 1 injured in a building collapse, and 1 hurt by a fallen steel beam. Four patients, all with sagittal-plane spondyloptosis, had a complete neurological deficit (American Spinal Injury Association [ASIA] Grade A), and 1, with coronal-plane spondyloptosis, presented with an incomplete neurological deficit (ASIA Grade C). Four patients had sustained concurrent multisystem trauma. All patients underwent surgery: an isolated posterior fusion in 2 and combined posterior-anterior fusion in 3. Only the patient with an incomplete neurological deficit (coronal-plane spondyloptosis) recovered neurological function postoperatively. CONCLUSIONS: Traumatic thoracolumbar junction spondyloptosis is rare. Surgical reconstruction and stabilization allow for early mobilization and rehabilitation. In the present series, a patient with coronal-plane spondyloptosis presented with preserved neurological function. This may be due to the result of differences in resultant neurological compression due to displacement mechanics compared with sagittally displaced injuries.
