Objectives: To analyze clinical features, dosimetric parameters, and outcomes of osteoradionecrosis (ORN).
Study Design: Thirty-six patients with ORN who had been previously treated with radiotherapy (RT) were retrospectively identified between January 2009 and April 2014. ORN volumes were contoured on planning computed tomography (CT) scans. Near maximum dose (D2%), minimum dose (Dmin), mean dose (Dmean), and percentage of bone volume receiving 50 Gy (V50) were examined. Clinical and dosimetric variables were considered to compare ORN resolution versus ORN persistence.
Results: Median interval time from end of RT to development of ORN was 6 months. Of the ORN cases, 61% were located in the mandible. Dmean to affected bone was 57.6 Gy, and 44% had a D2% 65 Gy or greater. Smoking was associated with ORN persistence on univariate analysis, but no factors were found to impact ORN resolution or progression on logistic regression.
Conclusions: Prevention strategies for ORN development should be prioritized. Dose-volume parameters could have a role in preventing ORN.

This randomized-controlled study evaluates the effectiveness of a newly developed social cognition rehabilitation intervention, the modified Social Cognition Individualized Activity Lab (mSoCIAL), in improving social cognition and clinical and functional outcomes of persons with schizophrenia recruited in two Italian sites: University of Campania "Luigi Vanvitelli" in Naples and ASST Fatebenefratelli-Sacco in Milan. mSoCIAL consists of a social cognitive training module focusing on different domains of social cognition and of a narrative enhancement module. We assessed changes in social cognition, clinical characteristics and functional variables in patients with schizophrenia who participated in 10 weekly sessions of mSoCIAL or received treatment as usual (TAU).

The objective of this study was to evaluate the utility of inflammation-based prognostic scores (IBPS) in predicting ORN among patients undergoing superselective intra-arterial chemoradiotherapy (SSIACRT). This retrospective cohort study examined the medical records of 54 patients with advanced oral cancer (stage 3 or 4) treated with SSIACRT. The predictor variable was IBPS.

Objectives: Osteoradionecrosis (ORN) following radiation therapy (RT) is a serious complication for patients undergoing head and neck cancer treatment. Recent literature has found an association between ipsilateral external carotid artery (ECA) diameter and the development of ORN. This study evaluates microvascular free-flap arterial anastomosis diameter and the development of ORN.

Objective: This study aims to summarize the clinical characteristics of skull base osteoradionecrosis (ORN) with the internal carotid artery (ICA) involvement and to distill the key surgical techniques that can enhance the protective measures for ICA.
Methods: We conducted a retrospective, observational study over a six-year period from February 2017 to May 2023. We included patients who were diagnosed with osteoradionecrosis with invasion of the internal carotid artery and collected their demographic information, pathology results, complication rates, ect.

Potassium is the most represented intracellular electrolyte in the human body. Its extracellular levels are maintained within strict limits through different mechanisms, which constitute the homeostasis of potassium. Hyperkalemia is the most common electrolyte disorder in patients with cardiovascular disease.
