Incidence and clinical significance of postoperative delirium after brain tumor surgery.

Background: Delirium is an acute and reversible deterioration of mental state. Postoperative delirium (POD) can develop after surgical procedures and is associated with impaired health status and worse recovery. So far, there is little data about postoperative delirium after brain surgery.

Digit ratio (2D:4D) in primary brain tumor patients: A case-control study.

Background: The second-to-fourth digit ratio (2D:4D) reflects prenatal estrogen and testosterone exposure, and is established in utero. Sex steroids are implicated in development and progression of primary brain tumors.

Aims: To investigate whether there is a link between 2D:4D ratio and primary brain tumors, and age at presentation.
