Adding eosinophil count to EMERALD rules predicts subarachnoid haemorrhage better in emergency department.

Background: Subarachnoid haemorrhage (SAH) clinical decision rules can provide successful results in the differential diagnosis of non-traumatic headache.

Aim: The aim of this study is to investigate whether a laboratory parameter that can be added to clinical decision-making rules can better predict subarachnoid haemorrhages in patients presenting to the emergency department with headache.

Methods: We conducted a retrospective cohort study between March 2017 and March 2019.

Clinical comparison of patients with angiography: Negative perimesencephalic and nonperimesencephalic subarachnoid hemorrhages.

Aims: This study aimed to compare the clinical courses, complications, and clinical outcome scores of patients with perimesencephalic (PM) and nonperimesencephalic (n-PM) subarachnoid hemorrhage (SAH) with no vascular pathology observed on cerebral angiography.

Materials And Methods: This retrospective study included 52 of 310 patients who underwent cerebral digital subtraction angiography for SAH between October 2016 and April 2018. The patients were categorized into PM and n-PM groups based on the type of hemorrhage observed on brain CT.

Significance of Preoperative Prone Position Computed Tomography in Free Hand Subaxial Cervical Pedicular Screwing.

Objective: The subaxial cervical pedicle screwing technique shows powerful biomechanical properties for posterior cervical fusion. When applying a pedicle screw using the freehand technique, it is essential to analyse cervical computed tomography and plan the surgery accordingly. Normal cervical computed tomography is usually performed in the supine position, whereas during surgery, the patient lies in a prone position.

Paediatric High-Grade Intracranial Mesenchymal Chondrosarcoma: A Case Report with 6 Years of Follow-Up without Recurrence.

Introduction: Intracranial mesenchymal chondrosarcoma (MSC) is an extremely rare tumour that constitutes only 0.015% of all central nervous system tumours. These tumours usually originate from skull base synchondrosis and are often observed in young adults during their second and third decades of life.

The Effect of Straight or Lordotic Rods on Cervical Subaxial Alignment While Fusing C1-C2.

Background: The C1 lateral mass and C2 pedicle screw with rod fixation system has been used commonly in recent years. Despite the numerous reports on this technique in the literature, there are no studies regarding the effect of the angle of the rod used. We investigated the effect of rod angle on subaxial lordosis, cervical sagittal balance, and pain scores.
