Spontaneous abscess with intraventricular rupture in an immunocompetent adult without prior neurosurgical intervention.

Previously viewed as a culture contaminant, can cause infection following neurosurgical intervention. Its role in brain abscess in the immunocompetent, surgically naïve population has been infrequently reported. Herein, we describe an immunocompetent 55-year-old man with no risk factors found to have a thalamic abscess with intraventricular rupture.

Bacterial translocation as a cause of ventriculoperitoneal shunt infection: A case report.

Bacterial translocation as a mechanism of distal catheter infection may play a larger role in ventriculoperitoneal shunt infections than previously recognized.

Ventriculogallbladder Shunt: Percutaneous Transhepatic Placement of the Distal Catheter.

Background: Ventriculogallbladder (VGB) shunts are currently placed as a salvage procedure in treatment of hydrocephalus when all other options are exhausted. Although VGB shunts work well when successfully implanted, they are still rarely used because of the technical challenges with the traditional surgical technique.

Objective: To implant VGB shunts using a minimally invasive technique that is safer and less technically challenging.

Increased plasmin-mediated proteolysis of L1CAM in a mouse model of idiopathic normal pressure hydrocephalus.

Idiopathic normal pressure hydrocephalus (iNPH) is a common neurological disorder that is characterized by enlarged cerebral ventricles, gait difficulty, incontinence, and dementia. iNPH usually develops after the sixth decade of life in previously asymptomatic individuals. We recently reported that loss-of-function deletions in lead to the development of iNPH in a subgroup of patients, but how this occurs is poorly understood.

Evidence for increased intraabdominal pressure as a cause of recurrent migration of the distal catheter of a ventriculoperitoneal shunt: illustrative case.

Background: Placement of a ventriculoperitoneal (VP) shunt is an effective treatment for several disorders of cerebrospinal fluid flow. A rare complication involves postoperative migration of the distal catheter out of the intraperitoneal compartment and into the subcutaneous space. Several theories attempt to explain this phenomenon, but the mechanism remains unclear.
