The impact of the use of intraoperative radiotherapy on costs, travel time and distance for women with breast cancer in the Mexico City Metropolitan Area.

Background And Objectives: The low availability and poor access to external beam radiotherapy (EBRT) in developing countries makes it hard for women with breast cancer to receive breast conservation. We studied the effect of providing intraoperative radiotherapy (IORT) on the travel time, distance, and costs of in the Mexico City Metropolitan Area (MCMA).

Methods: Sixty-nine patients treated between January 2013 and September 2014 were analyzed.

Previously unappreciated carotid artery stenosis diagnosed by cone beam computerized tomography.

Stroke is the third leading cause of death in the western world. Calcification noted on cone beam computerized tomography, frequently used to evaluate the maxillofacial structures for extent of tumor, trauma, and implant placement, may indicate atherosclerotic disease in the carotid artery. Internal carotid artery stenosis is a recognized risk factor for stroke; multiple, large randomized controlled trials have demonstrated a decreased risk of stroke after repair of the stenotic artery.

The prevalence and significance of anatomic variance in the mandibular symphysis: a retrospective study.

As computerized tomography (CT) becomes more widespread in implant treatment planning, dentists are bound to encounter more uncharacteristic anatomical conditions in the jaws. This retrospective study examined the prevalence of one such anatomic variance on 78 CT scans of human mandibles. Irregular heterogeneous circular radiopacities with internal radiolucencies were present in a majority (97.
