Assessment of the Accuracy of Ultrasonographically Measured Optic Nerve Sheath Diameter as a Surrogate for the Detection of Intracranial Hypertension Compared to Optic Nerve Sheath Diameter Measured by MRI: A Prospective Observational Study.

Background: Ultrasonographic measurement of optic nerve sheath diameter (ONSD) has been proposed as a non-invasive, bedside method to detect raised intracranial pressure (ICP) in various clinical settings. We aimed to correlate the ONSD obtained by ultrasonography (USG) with the ONSD obtained by magnetic resonance imaging (MRI) and to find its measurement accuracy.
Methodology: A prospective double-blind study was carried out by performing ocular ultrasounds on 32 patients with clinical features of intracranial hypertension.

Post-comatose disorders of consciousness (DoC) represent persistent neurological conditions with limited therapeutic options and a poor prognosis. Recent works advocate for exploring the effects of psychedelics to enhance brain complexity in DoC and ameliorate their consciousness. We investigated sub-anesthetic concentration of the atypical psychedelic ketamine for treating post-comatose prolonged DoC through a double-blind, placebo-controlled, cross-over trial involving three adult patients.

Department of Regional Health Research, University of Southern Denmark, Odense, Denmark.
Background: The objective was to investigate if cryoneurolysis were superior to sham in reducing pain intensity in patients with chronic knee osteoarthritis. We hypothesized that cryoneurolysis was an effective and safe therapy to reduce chronic pain in patients with knee osteoarthritis.
Methods: The study was a randomized, double-blind, sham-controlled.
Effect of Dexmedetomidine on Blood Loss and Patient Outcomes in Orthognathic Surgery: A Randomised Clinical Trial.
Int Dent J
January 2025
Department of Dental Pathology, Faculty of Dentistry, Chulalongkorn University, Bangkok, Thailand.
Introduction And Aims: Blood loss is a common side-effect in orthognathic surgery. Deliberated hypotensive anaesthesia can reduce blood loss. The purpose was to evaluate the effect of add-on dexmedetomidine compared with the usual hypotensive drug bolus on blood loss and patient outcomes in orthognathic surgery.
