Ultrasound-guided diagnosis of occult mandibular osteomyelitis.

Background: Skin and soft-tissue infections (SSTIs) are common disease presentations to the emergency department (ED), with the majority of the infections attributed to community-acquired methicillin-resistant Staphylococcus aureus. Rapid and accurate identification of potentially serious SSTIs is critical. Clinician-performed ultrasonography (CPUS) is increasingly common in the ED, and assists in rapid and accurate identification of a variety of disease processes.

Evaluation of SOX2 as a potential marker for ameloblastic carcinoma.

Objective: Ameloblastic carcinoma often poses diagnostic challenges in its separation from benign ameloblastoma with atypical cytologic features or an unusual clinical course. This study aimed to determine whether SOX2 (sex determining region-Y-related high mobility group box 2), a protein expressed in the epithelial basal proliferative zone in dentigerous cysts, is a marker for ameloblastic carcinoma as well as for high-grade transformation in ameloblastic neoplasms.

Study Design: Immunoperoxidase stains were performed according to a standard protocol.
