A Prospective Study of a Custom-Made Eco-Friendly Thyroid Shield: A Breakthrough in Radiation Protection.
Cureus
December 2024
Department of Oral Medicine and Radiology, Drs Sudha and Nageswara Rao Siddhartha Institute of Dental Sciences, Vijayawada, IND.
Background The thyroid gland is the most susceptible organ to radiation during the exposure of teeth because the thyroid area appears to be within the primary beam, and the dose levels are relatively high even after using collimation. This study aims to develop an eco-friendly thyroid shield by reusing lead foils from intra-oral periapical radiographic films and evaluate its effectiveness in intraoral radiography. Methods A total of 16 patients undergoing endodontic procedures who gave written consent to participate in the study were included and divided into four categories: anterior, canine, premolar, and molar.

Int J Surg Case Rep
January 2025
Department of Thoracic Surgery, Damascus Hospital,Damascus, Syria.
Introduction And Significance: Zenker's diverticulum is a rare condition characterized by a false diverticulum, as a true diverticulum involves herniation of all wall layers outward. Dysphagia, difficulty in swallowing, is the most common symptom. Diagnosis is primarily made through X-ray studies using contrast material during swallowing.

Methods: The study consisted of six stages: preparation of femur from a healthy dog cadaver; digitalization of the bone through a 3D scanner and creation of the base model; creation of a 3D AMDFD based on the image of the base model, 3D modeling carried out to reproduce five different types of diaphyseal fractures; printing the models produced on a 3D printer with a thermoplastic material; insertion of neodymium magnets in the fracture line to allow the assembly and disassembly of the parts; and radiography of 3D AMDFD in lateromedial and craniocaudal positions.
Results: The base model and 3D AMDFD had high precision in the replication of bone structures, like the bone in natura.
Fluid structure Interaction analysis for rupture risk assessment in patients with middle cerebral artery aneurysms.
Sci Rep
January 2025
Department of Neurosurgery, Kepler University Hospital and Johannes Kepler University Linz, Wagner-Jauregg Weg 15, 4020 Linz and Altenbergerstrasse 69, Linz, 4040, Austria.
Accurate rupture risk assessment is essential for optimizing treatment decisions in patients with cerebral aneurysms. While computational fluid dynamics (CFD) has provided critical insights into aneurysmal hemodynamics, most analyses focus on blood flow patterns, neglecting the biomechanical properties of the aneurysm wall. To address this limitation, we applied Fluid-Structure Interaction (FSI) analysis, an integrative approach that simulates the dynamic interplay between hemodynamics and wall mechanics, offering a more comprehensive risk assessment.

Medicine (Baltimore)
November 2024
Department of Joint and Hand Orthopedics, Hunan University of Medicine General Hospital, Huaihua, China.
Rationale: As a rare cause of femoral neck fracture, usually, hyperparathyroidism is missed diagnosed by orthopedist. Patient can present with various disappearance of clinical manifestations. Primary hyperparathyroidism in senile male population is commonly an asymptomatic disorder discovered incidentally through routine lab testing.
