BACKGROUND AND PURPOSE Imaging of patients with a clinical diagnosis of mandibular osteoradionecrosis (ORN) is often performed to support that clinical suspicion, evaluate the extent of the disease, or exclude coexistent tumor recurrence. The purpose of our study was to describe the clinical, MR imaging, and CT features of five patients with mandibular ORN associated with prominent soft-tissue ...

: Osteoradionecrosis (ORN) following radiation therapy is a much-feared complication of the treatment head and neck cancer. Free flap reconstruction in ORN patient has specific challenges for surgeon. From 2014 to 2020 Head Neck Microvascular unit Oral Maxillofacial Surgery Division at Jackson Health/University Miami treated 149 patients with free reconstruction. The fibula (n=65) anterior late...

Plants facing adverse conditions usually alter proline (Pro) metabolism, generating changes that help restore the cellular homeostasis. These organisms synthesize Pro from glutamate (Glu) or ornithine (Orn) by two-step reactions that share Δ(1) pyrroline-5-carboxylate (P5C) as intermediate. In the catabolic process, Pro is converted back to Glu using a different pathway that involves Pro dehydr...

BACKGROUND Direct microscopy, anaerobic culture and DNA-DNA hybridization have previously demonstrated an association between microorganisms and osteoradionecrosis (ORN). The purpose of our study was to use culture independent molecular techniques to detect bacteria in necrotic bone lesions of the mandible after radiation therapy. DESIGN Bacterial DNA was extracted from eight deep medullar sp...

Over the last decades, several therapeutic options were considered in the treatment of the osteoradionecrosis (ORN) of the mandible, including supportive measures, ultrasound therapy, corticosteroids, hyperbaric oxygen, surgical resection with reconstruction, and, more recently, drugs capable of reversing the fibroatrophic process. Once established, the ORN does not spontaneously disappear and ...

This study evaluates the event-related potential (ERP) components in a single outcome gambling task that involved monetary losses and gains. The participants were 50 healthy young volunteers (25 males and 25 females). The gambling task involved valence (loss and gain) and amount (50 cent and 10 cent) as outcomes. The outcome-related negativity (ORN/N2) and outcome-related positivity (ORP/P3) we...

Osteoradionecrosis (ORN) of the jaw is a significant complication of radiotherapy for oral cavity cancer. In addition to antibiotic medication, treatment options such as hyperbaric oxygen therapy, surgical approaches, and combined therapy with pentoxifylline and tocopherol have been recently introduced. In this review article, we will discuss the definition and classifications of osteoradionecr...

Entity-Relationship and UML class diagrams allow users to model the structural relationships, i.e., associations, that occur between entities or objects. By extending these diagrams with Object Relationship Notation (ORN), users can model the semantics of a variety of common association types with improved precision. Mapping these semantics to SQL, however, is very difficult. Here, we provide a...
