Hippocampal volume as treatment predictor in antidepressant naïve patients with major depressive disorder.

Major depression disorder (MDD) limits psychosocial functioning and quality of life. One of the biological alterations is a hippocampal volume (HV) reduction. Previous prospective neuroimaging studies present inconsistencies regarding HV reductions and clinical features and response of antidepressant treatment of the participants.

Avoiding iatrogenic injuries to the vertebral artery: A morphometric study of the vertebral artery-free dissection area.

Objective: To determine the area of a safety window that excludes the vertebral artery for the safe access of the occipital condyle screws during occipitocervical fixation.

Methods: This study included 138 cervical computed tomography angiograms. Six measurements per side were made in each imaging study.

Clinical and surgical implications regarding morphometric variations of the medial wall of the orbit in relation to age and gender.

The ethmoidal foramens are located on the medial wall of the orbit and are key reference points for intraoperative orientation. Detailed knowledge of the anatomy, bony landmarks and morphometric characteristics of the medial wall of the orbit is essential for various surgical procedures. The aim of this study was to determine the morphometric variations in the medial wall of the orbit and establish significant variations regarding age and gender.
