Insights from using biplanar intersection for freehand frontal ventriculostomy: a retrospective case-control study with virtual simulation.

Background: Frontal ventriculostomy (FV) is essential in neurosurgery; however, traditional freehand puncture methods have low accuracy, and ultrasound guidance is time consuming and expensive. To improve freehand puncture accuracy, this study introduced a biplanar intersection (BI) method, and analyzed the frontal-horn puncture mechanism. No related reports exist to date.

Protective effect of ligustrazine on oxidative stress and apoptosis following testicular torsion in rats.

Testicular torsion is a common urologic emergency and one of the causes of infertility in males. It has been reported that ligustrazine may decrease oxidative stress and reduce ischemia-reperfusion injury. This study aims to investigate the protective effect of ligustrazine in ischemia-reperfusion injury after testicular torsion-detorsion.

Assessment of a 3D printed simulator of a lateral ventricular puncture in interns' surgical training.

Purpose: In this study, a simulator for training lateral ventricular puncture (LVP) was developed using three-dimensional (3D) printing technology, and its function of improving the skills of LVP in young interns was evaluated.

Methods: A virtual 3D craniocerebral simulator of a 51-year-old female patient with hydrocephalus was reconstructed with 3D printing technology. The anatomical and practical validity were assessed by all interns on a 13-item Likert scale.

Effect of baicalin on hippocampal damage in kainic acid-induced epileptic mice.

The aim of the present study was to determine the effect of baicalin on the expression of miR-497 and its target B-cell lymphoma-2 (Bcl-2) in the hippocampus of kainic acid (KA)-induced epileptic mice. To establish status epilepticus (SE), 0.1 µg/5 µl KA was injected into the lateral cerebral ventricle in mice, which then received an intraperitoneal injection of baicalin (100 mg/kg) after 1 and 8 h.

Secondary headache due to aspergillus sellar abscess simulating a pituitary neoplasm: case report and review of literature.

Fungal sellar abscess is rare. A 42-year-old man was admitted with 2-month headache characterized by right peri-orbital pain. An intrasellar mass was found to be simulated a pituitary neoplasm after magnetic resonance imaging examination, and operated on via an endoscopic trans-sphenoidal approach.
