Objectives: The aim of this study was to generate an objective method to describe MRI data to assess response in the vertebrae of patients with metastatic hormone sensitive prostate cancer (mHSPC), treated with external beam radiation therapy and systemic therapy with Radium-223 and to correlate changes with clinical outcomes.

Methods: Three sets of whole-body MRI (WBMRI) images were utilized from 25 patients from the neo-adjuvant Androgen Deprivation Therapy pelvic Radiotherapy and RADium-223 (ADRRAD) clinical trial: MRI1 (up to 28 days before Radium-223), MRI2, and MRI3 (2 and 6 months post completion of Radium-223). Radiological response was assessed based on post baseline MRI images.

Aims: Cardiac disease is a dose-limiting toxicity in non-small cell lung cancer radiotherapy. The dose to the heart base has been associated with poor survival in multiple institutional and clinical trial datasets using unsupervised, voxel-based analysis. Validation has not been undertaken in a cohort with individual patient delineations of the cardiac base or for the endpoint of cardiac events.

This study aimed to validate a bespoke 3D-printed phantom for use in quality assurance (QA) of a 6 degrees-of-freedom (6DoF) treatment couch. A novel phantom design comprising a main body with internal cube structures, was fabricated at five centres using Polylactic Acid (PLA) material, with an additional phantom produced incorporating a PLA-stone hybrid material. Correctional setup shifts were determined using image registration by 3D-3D matching of high HU cube structures between obtained cone-beam computer tomography (CBCT) images to reference CTs, containing cubes with fabricated rotational offsets of 3.

Introduction: Radiation cardiotoxicity is a dose-limiting toxicity and major survivorship issue for patients with non-small cell lung cancer (NSCLC) completing curative-intent radiotherapy, however patients' cardiovascular baseline is not routinely optimised prior to treatment. In this study we examined the impact of statin therapy on overall survival and post-radiotherapy cardiac events.

Methods: Patients treated between 2015-2020 at a regional center were identified.

Objective: To test the hypothesis that chronic treatment of early-stage Huntington disease (HD) with high-dose coenzyme Q10 (CoQ) will slow the progressive functional decline of HD.

Methods: We performed a multicenter randomized, double-blind, placebo-controlled trial. Patients with early-stage HD (n = 609) were enrolled at 48 sites in the United States, Canada, and Australia from 2008 to 2012.

Purpose: Organ motion is a contributory factor to the variation in location of the prostate and organs at risk during a course of fractionated prostate radiation therapy (RT). A prospective randomized controlled trial was designed with the primary endpoint to provide evidence-based bladder-filling instructions to achieve a consistent bladder volume (BV) and thus reduce the bladder-related organ motion. The secondary endpoints were to assess the incidence of acute and late genitourinary (GU) and gastrointestinal (GI) toxicity for patients and patients' satisfaction with the bladder-filling instructions.

Objectives: To evaluate the cost-effectiveness of alternative approaches to revascularization for patients with three-vessel or left main coronary artery disease (CAD).

Background: Previous studies have demonstrated that, despite higher initial costs, long-term costs with bypass surgery (CABG) in multivessel CAD are similar to those for percutaneous coronary intervention (PCI). The impact of drug-eluting stents (DES) on these results is unknown.

Mycetoma, also known as madura foot, is a local, chronic, slowly progressive disease with the classic presentation involving tumefaction, multiple draining sinuses, and grain-filled pus. It is primarily produced by either a bacteria (actinomycetoma) or a fungal (eumycetoma) organism. Determining the causative organism is fundamental to the treatment process.

Hereditary multiple exostoses is a relatively uncommon disorder of endochondral bone characterized by the presence of multiple, cartilaginous-capped exostoses arising from the metaphyses. A rare presentation of hereditary multiple exostoses in the calcaneus of a 35-year-old man is reviewed and discussed. A brief review of the literature is provided, as well as a discussion of the patient's family history.

Hemangiomas of bone are rare lesions accounting for approximately 1% of all primary bone tumors. Intraosseous hemangiomas of the foot are especially rare, with only sparse reports in the literature. Presented here is a case study of an erosive bony lesion of the midfoot that was microscopically and histopathologically proven to be a mixed cavernous and capillary hemangioma.

Osteomyelitis and osteoarthropathy may appear clinically and radiographically similar. Many retrospective and some prospective studies have shown that magnetic resonance imaging provides valuable information about the pathologic basis of disease, specifically in the differentiation of osteomyelitis from osteoarthropathy. Although culture and biopsy of bone are the definitive diagnostic procedure, this may not always be possible.

The laterally comminuted fracture-dislocation of the ankle can be associated with devastating consequences. Previously described surgical as well as nonsurgical-treatment results have been disappointing. Accurate anatomical reduction and rigid fracture stabilization of a comminuted fibula can be extremely difficult.

Acute dysvascular limb in young adults is a rare entity. Diagnosis is often difficult because symptoms are not recognized as ischemic. The most common causes of this condition are premature atherosclerosis, thromboangiitis obliterans, microemboli, popliteal entrapment syndrome, collagen vascular disease, Takaysu's arteritis, and coagulopathy.
