This case report emphasizes the diagnostic role of cone-beam computed tomography (CBCT) in identifying a rare pediatric case of ameloblastic fibroma (AF), comprising approximately 2% of odontogenic tumors. The 10-year-old patient initially presented with painless left mandibular posterior gingival swelling, resembling radicular or dentigerous cysts in clinical and conventional radiographic assessments. However, CBCT revealed a distinct periapical radiolucency linked to deciduous molar roots and an unerupted premolar, exposing mandibular lingual plate thinning and buccal plate disruption.

Embryo models offer opportunities for understanding development and advancing medicine but rely on intricate procedures with limitations in efficiency and developmental fidelity. Here, we employ a small-molecule-only approach to induce mouse embryonic stem cells into 8- to 16-cell-like embryo founder cells, enabling the generation of a complete embryo model. These founder cells specify all blastocyst lineages, both embryonic and extraembryonic, in vivo and in vitro.

Background: The Da Silva Cone procedure for Ebstein anomaly has dramatically improved tricuspid valve competence and clinical outcomes. However, preoperative left ventricular (LV) dysfunction and immediate postoperative right ventricular (RV) systolic dysfunction are frequently observed. While excellent valve outcomes are well established, recovery of biventricular function following the Cone remains less defined.

Introduction And Objectives: Retinitis pigmentosa (RP) represents a spectrum of rod-cone inherited disorders with characteristic symptoms, and functional changes. The Asp-190-Tyr pathogenic variant of the RHO gene impairs rodopsin transport through the endoplasmic reticulum, leading to accumulation within photoreceptors, inducing cytotoxicity. This report presents the ophthalmologic phenotype of this rare variant.
