Comparison of pressure controlled, volume controlled, and volume guaranteed pressure controlled modes in prone position in patients operated for lumbar disc herniation: A randomized trial.

Background: To compare pressure-controlled ventilation (PCV), volume-controlled ventilation (VCV), and pressure-controlled ventilation-volume guaranteed (PCV-VG) modes in patients undergoing spinal surgery in the prone position under general anesthesia.

Methods: The study included 78 patients aged 20 to 80 years, American Society of Anesthesiologists 1-2, scheduled for lumbar spinal surgery. Patients included in the study were randomly divided into 3 groups Group-VCV; Group-PCV; Group-PCV-VG.

Effects of Pterional and Osteoplastic Craniotomy on Temporalis Muscle and Calvarial Bone Graft Atrophy.

This study aims to compare the effects of osteoplastic craniotomy on temporalis muscle and bone graft atrophy in patients operated on with a pterional approach to the standard technique. Patients operated on for an intracranial aneurysm with a pterional approach between 2014 and 2018 were studied. Following the exclusion criteria, 36 patients were included in this retrospective study.

Identification of Attention-Deficit-Hyperactivity Disorder Subtypes Based on Structural MRI Grey Matter Volume and Phenotypic Information.

Background: One of the neurodevelopmental disorders widely affecting school-aged children in recent years is attention deficit hyperactivity disorder (ADHD). In many neurodevelopmental disorders, grey matter may be used as a clinical indicator by looking at MRIs.

Objective: The study aimed to segment grey matter from brain MRI using a proposed fuzzy c-means clustering-based technique for the detection of ADHD and its subtypes (ADHD-Inattentive, ADHDHyperactive, and ADHD-Combined).

Preoperatively, Which Parameter Allows Us to Predict the C5 Palsy After Cervical Open-Door Laminoplasty?

Aim: To uncover factors that can predict the development of C5 palsy before surgery by evaluating several different parameters.

Material And Methods: A total of 177 patients who underwent surgery between 2015 and 2020 were included in the study. In total, C5 palsy was observed in 22 (12.
