Impact of BrainLab VectorVision Infrared-Based Neuronavigation on Surgical Outcomes in Intracranial Meningioma Patients: A Retrospective Study.

BACKGROUND The BrainLab VectorVision neuronavigation system is an image-guided, frameless localization system used intraoperatively, which includes a computer workstation for viewing and analyzing operative microscopic images. This retrospective study aimed to evaluate the use of the BrainLab VectorVision infrared-based neuronavigation imaging system in 80 patients with intracranial meningioma removed surgically between 2013 and 2023. MATERIAL AND METHODS Data were retrospectively collected from 36 patients with convexity meningioma and 44 patients with parasagittal meningioma between 2013 and 2023.

The Insidious Enemy of the Liver: The Situation in Childhood Acetaminophen Poisoning and Early N-AC Treatment.

Methods: This study was designed as a cross-sectional, observational, retrospective study. The variables of the study were paracetamol overdose, demographic information, poisoning mechanisms, clinical, laboratory findings, and clinical progression of the cases. The cases compared in whom treatment was initiated within the first 8 hours after poisoning and those in whom it was not.

Multimodal ultrasonography evaluation in thyroid nodule characterization: what is the ideal algorithm?

Aims: The aim of this study is to investigate the diagnostic performances of Ultrasonography (US), Shear-wave Elastography (SWE), and Superb Microvascular Imaging (SMI) findings in the diagnosis of malignant thyroid nodules (MTNs) and to determine the US algorithm with the best diagnostic performance.

Material And Methods: Eighty-one nodules in 77 patients who had underwent multimodal US with biopsy results, were evaluated. Echogenicity, nodule components, contours, presence and type of calcification, and size were analyzed with US.

Reimagining the Rheumatology Fellowship Interview: Using Participatory Design-Thinking Process to Create a More Applicant-Centered Experience.

Objective: Design thinking is a creative problem-solving process used to better understand users' needs and experiences so that a product or service can be improved. Its emphasis on empathy, iterative prototyping, and participatory collaboration make it an ideal methodology for innovation in medical education. We apply this framework to the virtual rheumatology fellowship interview process so that interviews can become more applicant centered.

Can the greater trochanter/femoral neck signal intensity ratio on coronal T1 weighted images of the hip differentiate normal-abnormal bone mineral density?

Unlabelled: A simple index calculated by dividing the greater trochanter signal intensity by that of the femoral neck on coronal T1-weighted magnetic resonance images of the hip may be useful as an opportunistic screening tool to differentiate normal vs. abnormal bone mineral density.

Purpose: The aim of this study is to evaluate the efficacy of the greater trochanter/femoral neck (T/N) signal intensity (SI) ratio on T1 weighted images of the hip in differentiating patients with normal vs.
