Quantitative assessment of post-operative recurrence of chronic subdural haematoma using mean haematoma density.

Purpose: The purpose of this study was to establish a quantitative method with which to assess the post-operative recurrence of chronic subdural haematoma (CSDH).

Methods: CT scans were reviewed from 44 consecutive patients with CSDHs who underwent burr hole drainage between July 2008 and January 2012. The area of the haematoma was quantified according to the mean haematoma density (MHD) using computer-based image analysis of pre-operative brain CT scans.

Correlation between Glasgow coma score components and survival in patients with traumatic brain injury.

Background: The Glasgow coma scale (GCS) score is used in the initial evaluation of patients with traumatic brain injury (TBI); however, the determination of an accurate score is not possible in all clinical situations. Our aim is to determine if the individual components of the GCS score, or combinations of them, are useful in predicting mortality in patients with TBI.

Methods: The components of the GCS score and the receiver-operating characteristic (ROC) curves were analyzed from 27,625 cases of TBI in Taiwan.
