Three-dimensional cone-beam computed technology evaluation of skeletal and dental changes in growing patients with Class II malocclusion treated with the cervical pull face-bow headgear appliance.

Introduction: This study aimed to 3-dimensionally quantify and compare the outcomes of growing patients with Class II malocclusion treated with the cervical pull face-bow headgear appliance in combination with full fixed orthodontic appliances.

Methods: The study sample consisted of 22 patients with Class II malocclusion with the following inclusion criteria: ANB >4.75°, Class II molar relationship, and SN-GoGn <37°.

Complete postsurgical left ventricular-aortic discontinuity and pseudoaneurysm formation.

Background: Left ventricular outflow tract pseudoaneurysm is a rare but potentially fatal complication of aortic valve replacement, infective endocarditis (IE), and suture dehiscence. Left ventricular-aortic discontinuity is a severe and uncommon manifestation of IE. For patients who have a long-standing history of endocarditis, periannular lesions in the aortic valve may rupture, leading to the rare occurrence of complete, or total, left ventricular-aortic discontinuity.

A Lost Bullet in the Coronary Sinus: A Cautionary Tale.

We present a case of venous bullet embolism to the right atrium following a gunshot wound (GSW) to the abdomen. A 53-year-old male presented after a GSW to the abdomen. His workup included a computed tomography (CT) scan demonstrating an aortic injury with aortocaval fistula.
