Introduction: The objective of this two-arm split-mouth randomized trial, was to evaluate the ability of fluoride-releasing resin composite to prevent demineralization and white spot lesion (WSL) formation, during orthodontic treatment with fixed appliances. Methods: Patients needing comprehensive orthodontic treatment were randomly allocated into two groups, according to the half split-mouth technique. This trial examined a total of 300 teeth in each group: the control group, in which brackets were fixed with a non-fluoride-containing adhesive resin; and the intervention group, in which brackets were fixed with a fluoride-containing adhesive resin...

Aims: Despite the use of 3D mapping systems and new developments of non-fluoroscopic options, most centres still rely at least in part on fluoroscopy for catheter visualization during catheter ablations. The purpose of this study was to assess the feasibility of using an ultra-low frame rate and antiscatter grid-less radiation protocol during complex left atrial ablations to minimize radiation exposure for the patient and staff. Methods and results: A total of 150 consecutive patients undergoing left atrial ablations in our hospital were included in the analysis...

Aims: Assessment of left ventricular (LV) volumes and ejection fraction (LVEF) with cardiac imaging is important in the selection of patients for cardiac resynchronization therapy (CRT). Several observational studies have explored the role of imaging-derived LV dyssynchrony parameters to predict the response to CRT, but have yielded inconsistent results, precluding the inclusion of imaging-derived LV dyssynchrony parameters in current guidelines for selection of patients for CRT. METHODS: The EuroCRT is a large European multicentre prospective observational study led by the European Association of Cardiovascular Imaging...

BACKGROUND: Thyroid incidentaloma is defined as an unsuspected thyroid lesion found on imaging study or while performing a surgery non-related to the thyroid gland. Most recent scientific literature tends to demonstrate a detection rate of 0.1-4.3% for incidental findings of thyroid focal uptake identified by (18)F-fluorodeoxyglugose Positron Emission Tomography with computed tomography ((18)FDG-PET/CT) initially prescribed for nonthyroid disease. From 10.3 to 80.0% of patients who underwent further evaluation are diagnosed with malignant lesions...

INTRODUCTION: Spondylodiscitis refers to infections of the intervertebral disc and the adjacent vertebral body. Although it is still considered a rare condition, its rate is projected to increase. Mortality rate is considered to be low, but an estimated one third of the survivors experience residual disabilities. Literature shows that uncomplicated spondylodiscitis can be adequately treated by early antibiotic therapy and immobilization. The aim of the study is to evaluate the outcome of conservative treatment in patients with haematogenous spondylodiscitis...

Graft failure represents a leading cause of mortality following organ transplantation. Acute late-onset graft failure has not been widely reported. This paper describes the demographics, CT imaging pathology findings and treatment of patients presenting with the latter. A retrospective review of lung transplant recipients at 2 large-volume centres was performed. Acute late-onset graft failure was defined as sudden onset of bilateral infiltrates with an oxygenation index <200 without identifiable cause or concurrent extra-pulmonary organ failure...

REVIEW
Thomas D Coates, John C Wood
Blood transfusion plays a prominent role in the management of patients with sickle cell disease (SCD), but causes significant iron overload. As transfusions are used to treat the severe complications of SCD, it remains difficult to distinguish whether organ damage is a consequence of iron overload or is due to the complications treated by transfusion. Better management has resulted in increased survival, but prolonged exposure to iron puts SCD patients at greater risk for iron-related complications that should be treated...

BACKGROUND: Incidental meningiomas are increasingly being diagnosed due to widespread use of brain imaging. Treatment options include surveillance, surgery and stereotactic radiosurgery, but the natural history of these tumours is not fully understood and there are no accepted management guidelines to aid clinical decision-making. The aim of this study was to assess current practice in the United Kingdom and identify areas of variation for further study. METHODS: A questionnaire was distributed to all members of the Society of British Neurosurgeons (SBNS)...

Treatment options for patients with thyroid cancer that is no longer sensitive to iodine therapy are limited. Those treatments which currently exist are associated with significant toxicity. The SELIMETRY trial (EudraCT No 2015-002269-47) aims to investigate the role of the MEK inhibitor Selumetinib in re-sensitising advanced iodine refractory differentiated thyroid cancer to radioiodine therapy. Patients deemed to have sufficient iodine uptake in previously iodine refractory lesions after 4 weeks of Selumetinib therapy will be given an empirical activity of 5...
