Suction forces generated by passive bile bag drainage on a model of post-subdural hematoma evacuation.

Acta Neurochir (Wien)

Article Synopsis
  • - This study aimed to measure the suction forces of a passive drainage system used after subdural hematoma evacuation, particularly focusing on bile bag drains.
  • - Researchers created a model and found that an empty bile bag generates minimal suction, but when the drain tube is fluid-filled, suction increases significantly due to siphoning, varying from 18.7 to 30.6 mmHg based on the bile bag's height.
  • - The results indicate that a passive bile bag drain is ineffective when empty, but can produce suction forces similar to other drainage systems when filled with fluid.

Article Synopsis
  • - This study investigates the timing of heparin administration after ventriculostomy in patients with subarachnoid hemorrhage (SAH) to assess safety and risk of hemorrhagic complications.
  • - It analyzed 46 patients and found that early heparinization (within 4 hours) led to a significantly higher rate of tract hemorrhages (58.8%) compared to those treated after 4 hours.
  • - The conclusion suggests delaying heparin use for at least 4 hours post-ventriculostomy to minimize the risk of serious complications in patients undergoing treatment for ruptured aneurysms.

Assessment of vascularity in glioblastoma and its implications on patient outcomes.

J Neurooncol

There is little data on why glioblastomas (GBM) hemorrhage and how it may affect patient outcomes. The aim of this study was to investigate the mechanisms of hemorrhage in glioblastoma by examining molecular and genetic features by immunohistochemistry (IHC) and mRNA expression profiles in association with imaging and clinical outcomes. An observational retrospective cohort analysis was performed on 43 FFPE GBM tissue samples.

Perineal pain secondary to tethered cord syndrome: retrospective review of single institution experience.

Childs Nerv Syst

November 2015

Division of Neurosurgery, Department of Surgery, University of Nebraska Medical Center, 982035 Nebraska Medical Center, Omaha, NE, 68198-2035, USA.

Article Synopsis
  • * A study reviewed 491 patients who underwent spinal cord detethering, finding that only 7 (1.4%) reported perineal pain or hypersensitivity before surgery.
  • * All 7 patients experienced complete resolution of perineal symptoms post-surgery, indicating that spinal cord detethering can effectively alleviate this specific symptom along with other initial symptoms in many cases.

Analysis of adjacent segment degeneration with laminectomy above a fused lumbar segment.

J Clin Neurosci

November 2013

Division of Neurosurgery, Department of Surgery, University of Nebraska Medical Center, 982035 Nebraska Medical Center, Omaha, NE 68198-2035, USA. Electronic address:

Although recent data suggests that lumbar fusion with decompression contributes to some marginal acceleration of adjacent segment degeneration (ASD), few studies have evaluated whether it is safe to perform a laminectomy above a fused segment. This study investigates the hypothesis that laminectomy above a fused lumbar segment does not increase the incidence of ASD, and assesses the benefits and risks of performing a laminectomy above a lumbar fusion. A retrospective review of 171 patients who underwent decompression and instrumented fusion of the lumbar spine was performed to analyze the association between ASD and laminectomy above the fused lumbar segment.

Long term follow-up after multiple hippocampal transection (MHT).

Seizure

November 2013

University of Nebraska Medical Center, Division of Neurosurgery, 982035 Nebraska Medical Center, Omaha, NE 68198-2035, USA. Electronic address:

Purpose: Multiple hippocampal transection (MHT) is a new surgical procedure which disrupts seizure propagation within the hippocampus without impairing verbal memory or the loss of stem cells. Since there are very few papers on this procedure, the authors are presenting their long term results to increase the database on this procedure.

Method: Long term outcome in 15 consecutive patients who had MHT for unlilateral temporal lobe epilepsy, had intra-operative electro-corticography (ECoG) and have a minimum follow-up of at least 2 years is presented.

A modified stereotactic frame as an instrument holder for frameless stereotaxis: Technical note.

Surg Neurol Int

October 2010

Division of Neurosurgery, University of Nebraska Medical Center, 982035 Nebraska Medical Center, Omaha, NE 68198-2035, USA.

Background: In order to improve the targeting capability and trajectory planning and provide a more secure probe-holding system, a simple method to use a stereotactic frame as an instrument holder for the frameless stereotactic system was devised.

Methods: A modified stereotactic frame and BrainLab vector vision neuronavigation sys¬tem were used together. The patient was placed in the stereotactic head-holder to which a reference array of the neuronavigation system was attached.

Occipital encephaloceles are the most common type of encephalocele encountered in the Western Hemisphere. The occipital encephalocele is typically classified according to the relationship of the herniated tissue to the torcular. We report the unusual case of a premature infant with a rare, large occipital encephalocele which encompassed the posterior superior sagittal sinus and torcular.

Role of Na(+)-Ca(2+) exchanger after traumatic or hypoxic/ischemic injury to spinal cord white matter.

Spine J

December 2003

Section of Neurosurgery, Department of Surgery, University of Nebraska Medical Center, 982035 Nebraska Medical Center, Omaha, NE 68198-2035, USA.

Background Context: Spinal cord injury is a devastating condition in which clinical disability results from demyelination of white matter tracts. Changes in glial-axonal signaling, and enhanced Ca(2+) channel activity with excessive accumulation of intracellular Ca(2+), is a common phenomenon after hypoxia/ischemia or mechanical trauma to spinal cord dorsal column white matter tracts leading to irreversible injury.

Purpose: In the present study we examined the role of Na(+)-Ca(2+) exchanger (NCX) at physiological temperatures after hypoxia/ischemia and compressive injury to spinal cord dorsal column white matter in vitro.
