A person presented with multiple gunshot injury. Chest x-ray & CT whole body trauma protocol was done which showed multiples pellets of bullet in abdomen and one bullet in elbow according to entry wound. There was an entry wound without any bullet in left maxillofacial region however there was no exit wound. A bullet was noticed in tracheobronchial tree. There was no pneumothorax any signs of chest trauma or any pneumomediastinum. It is assumed that the bullet first hit the left cheek (maxilla) and lost its momentum. As the patient lost consciousness and had a fall leading to inhalation (aspiration) of bullet in the airway. As per ballistic experts it was basically a jacketed metallic bullet. As bullet moved in airway, the outer metallic core reached the trachea near carina and the soft metallic core slipped more distally to right main bronchus and bronchus intermedius. While inspection the outer metallic capsule was seen in trachea just above carina which was hollow and was gently removed with the help of foreign body forceps. The core was removed with dormia basket without any mucosal tear. The favorable outcome can be attributed as patient had no lung contusion or chest trauma and bullet was inhaled which was not very old. The evolution of bronchoscopy started with rigid one but the fibreoptic bronchoscopy (FOB) has revolutionized the pulmonary interventions. The FOB can be used with minimal traumas under local anesthesia resulting in markedly reduced morbidity and mortality.

Firearm-related scenarios can be highly complex, involving multiple shooters, firearms, types of ammunition, victims, and various impact zones. Obtaining the maximum amount of information to connect each piece of the puzzle is crucial for resolving these cases. Currently, new tools are being developed in the forensic field that facilitate both fieldwork and laboratory analysis, enabling the estimation of trajectories, identification of shooters, and more.

Introduction: George Floyd's death in 2020 galvanised large protests around the country, including the emergence of the Capitol Hill Autonomous Zone (CHAZ) in Seattle, Washington, a non-policed, organised protest region that may have differing injury risks than other regions. We sought to quantitatively describe characteristics of injuries related to protests documented at visits to two nearby major emergency departments, including the only Level 1 trauma centre in the state.
Methods: Using the International Classification of Diseases, 10th Revision code inclusion criteria, we identified 1938 unique patient visits across the two emergency departments from 29 May 2020 and 1 July 2020.

Introduction: Arterio-enteric fistula is one of the extremely rare complications of penetrating trauma.
Case Presentation: A 27-year-old male presented to the emergency department with a gunshot to the right buttock. Initial assessments revealed a left femoral shaft fracture, the right buttock as the bullet inlet and the medial portion of the left thigh as an outlet, with no other significant findings.

This work aims to address key issues in the ballistic performance of ceramic-based composite armor, particularly at the joints of spliced bulletproof panels. The edge structure of C/C-SiC ceramic plates and ultra-high molecular weight polyethylene is redesigned to superimpose the joint areas. These structurally optimized composite pads are examined by numerical simulation of impact dynamics to understand their anti-penetration performance whose accuracy is then validated by live fire tests.

Objectives: Photon-counting detector CT (PCD-CT) is expected to substantially improve and expand CT-imaging applicability due to its intrinsic spectral capabilities, increased spatial resolution, reduced electronic noise, and improved image contrast. The current study aim is to evaluate PCD-CT efficacy in characterizing bullets based on their dimensions, shape, and material composition.
Materials And Methods: This is an observational phantom study examining 11 unfired, intact bullets of various common calibers, placed in ballistic gelatin.
