Dialysis Disequilibrium Syndrome and Intracranial Pressure Fluctuations in Neurosurgical Patients Undergoing Renal Replacement Therapy: Systematic Review and Pooled Analysis.

Background: Dialysis disequilibrium syndrome is a rare, well-known, potentially life-threatening complication of renal replacement therapy (RRT), often involving cerebral edema and increased intracranial pressure (ICP). However, the impact of RRT on ICP and rate of dialysis disequilibrium syndrome in neurosurgical patients have not been systematically assessed.

Methods: In February 2022, a systematic review following PRISMA guidelines was conducted using various combinations of 9 keywords in the MEDLINE database.

Through-and-through stab wound of the cervical spinal canal with retained weapon but no neurological repercussions: an exceptionally rare injury and the case for direct withdrawal. Illustrative case.

Background: Nonmissile penetrating spinal injuries are rare and potentially debilitating. Such injuries can sometimes be complicated by the retention of a foreign body, which is usually part of the assailant's weapon, making their management even more problematic.

Observations: We present a unique case of stab wound to the neck with a retained ice pick, traversing the spinal canal from one intervertebral foramen to the other, yet with no ensuing neurological damage to the patient.

Sinking bullet syndrome: A unique case of transhemispheric migration.

Background: Spontaneous migration of retained intracranial bullet fragments is an increasingly recognized phenomenon. However, such migration is usually limited in extent, since it occurs along the bullet tract or cerebrospinal fluid (CSF) spaces. Transhemispheric migration through an intact cerebral hemisphere has not been previously reported.
