Clinical outcome of root canal obturation using different based sealers: a retrospective cohort study.
BMC Oral Health
December 2024
Department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Sakarya University, Sakarya, Turkey.
Background: This study aimed to assess and compare the performance of root canal treatment obturated either with calcium silicate-based or epoxy resin-based root canal sealers on retreatment cases with periapical lesions.
Methods: Patients' radiographic data and clinical records were obtained retrospectively from the computerized patient record system. A total of 44 teeth, 28 teeth treated with calcium silicate-based sealer and 16 teeth treated with epoxy resin-based sealer, were included in the study.
Does new research address persistent questions since the publication of the CDC's 2018 pediatric mTBI guideline.
Childs Nerv Syst
December 2024
New York Medical College, Valhalla, NY, USA.
Background And Objective: Due to the potential debilitating sequelae following pediatric mTBI, the CDC published the Guideline on the Diagnosis and Management of mTBI Among Children in 2018. However, the guideline identified several key gaps in our clinical knowledge to support several clinical recommendations. The objective of this review is to evaluate if subsequent research has addressed these gaps in clinical practice recommendations.

December 2024
Department of Radiology, Northwestern Medicine, Northwestern University, Chicago, IL, USA.
Many tasks performed in image-guided procedures can be cast as pose estimation problems, where specific projections are chosen to reach a target in 3D space. In this study, we construct a framework for fluoroscopic pose estimation and compare alternative loss functions and volumetric scene representations. We first develop a differentiable projection (DiffProj) algorithm for the efficient computation of Digitally Reconstructed Radiographs (DRRs) from either Cone-Beam Computerized Tomography (CBCT) or neural scene representations.

Orthop Surg
December 2024
The First School of Clinical Medicine, Southern Medical University, Guangzhou, China.
Objectives: To minimize the risk of V3 segment of vertebral artery (VA) injury in the atlantoaxial dislocation (AAD) patients with C1 pedicle height less than 4.0 mm and provide a strong toggle force in irreducible AAD and revision surgery. We evaluated the feasibility of C1 "Zero Angle" screw (C1ZAS) and safe entry point with "in-out-in" technique as an alternative option for C1 pedicle screw (PS) in cases with AAD.

Ther Adv Musculoskelet Dis
November 2024
Department of Rheumatology, Amsterdam Rheumatology and Immunology Center, Amsterdam UMC, De Boelelaan 1117, 1081 HV Amsterdam, Amsterdam, The Netherlands.
Background: The efficacy and safety of bimekizumab (BKZ), an inhibitor of interleukin (IL)-17F in addition to IL-17A, has been established in axial spondyloarthritis (axSpA). Early assessment of new bone formation is possible using F-fluoride positron emission tomography-computerised tomography (PET-CT) imaging to quantitatively monitor osteoblastic activity.
Objectives: This exploratory study, initiated before phase IIb/III studies, assessed the efficacy and safety of BKZ in patients with radiographic (r-)axSpA and its effect on new bone formation.
