Intrathecal Baclofen Pump Migration Into the Peritoneal Cavity: A Case Report.

Introduction: Intrathecal baclofen pumps are valuable treatment options for those with cerebral palsy. Although subfascial baclofen pump placement is generally preferred over a subcutaneous pump placement due to lower infection rates, rare complications can occur with the subfascial approach such as pump migration.

Case Presentation: The authors here describe a case of baclofen pump migration into the peritoneal cavity of a 26-year-old male patient with cerebral palsy, shunted hydrocephalus, and epilepsy.

Feasibility of CT-based intraoperative 3D stereotactic image-guided navigation in the upper cervical spine of children 10 years of age or younger: initial experience.

OBJECT Rigid screw fixation may be technically difficult in the upper cervical spine of young children. Intraoperative stereotactic navigation may potentially assist a surgeon in precise placement of screws in anatomically challenging locations. Navigation may also assist in defining abnormal anatomy.

Transsylvian selective amygdalohippocampectomy for treatment of medial temporal lobe epilepsy: Surgical technique and operative nuances to avoid complications.

Background: A number of different surgical techniques are effective for treatment of drug-resistant medial temporal lobe epilepsy. Of these, transsylvian selective amygdalohippocampectomy (SA), which was originally developed to maximize temporal lobe preservation, is arguably the most technically demanding to perform. Recent studies have suggested that SA may result in better neuropsychological outcomes with similar postoperative seizure control as standard anterior temporal lobectomy, which involves removal of the lateral temporal neocortex.

Subacute posttraumatic ascending myelopathy in a 15-year-old boy.

Secondary injury following initial spinal cord trauma is uncommon and frequently attributed to mismanagement of an unprotected cord in the acute time period after injury. Subacute posttraumatic ascending myelopathy (SPAM) is a rare occurrence in the days to weeks following an initial spinal cord injury that is unrelated to manipulation of an unprotected cord and involves 4 or more vertebral levels above the original injury. The authors present a case of SPAM occurring in a 15-year-old boy who sustained a T3-4 fracture-dislocation resulting in a complete spinal cord injury, and they highlight the imaging findings and optimum treatment for this rare event.

Modified periinsular hemispherotomy: operative anatomy and technical nuances.

Surgical options for pediatric patients with marked dysfunction of a single epileptogenic hemisphere have evolved over time. Complications resulting from highly resective operations such as anatomical hemispherectomy, including superficial siderosis and secondary hydrocephalus, have led to the development of less resective and more disconnective functional hemispherectomy. Functional hemispherectomy has recently given rise to hemispherotomy, the least resective operation primarily aimed at disconnecting the abnormal hemisphere.

Bilateral ptosis as initial presentation of gliomatosis cerebri: case report.

Gliomatosis cerebri is a rare, diffuse glioma of neuroepithelial origin involving more than two cerebral lobes. Clinical presentation of gliomatosis cerebri is variable and depends on the degree, extent, and location of cortical involvement. Signs and symptoms related to supratentorial cortical involvement predominate and the diagnosis is reached through a combination of clinical, radiographic, and histopathological evaluations.

A calcineurin homologous protein is required for sodium-proton exchange events in the C. elegans intestine.

Caenorhabditis elegans defecation is a rhythmic behavior, composed of three sequential muscle contractions, with a 50-s periodicity. The motor program is driven by oscillatory calcium signaling in the intestine. Proton fluxes, which require sodium-proton exchangers at the apical and basolateral intestinal membranes, parallel the intestinal calcium flux.
