Non-Tumorous Diseases of the Sternum and Its Articulations: At the Front Gate of the Chest.

Abnormalities of the sternal and peri-sternal regions are commonly seen in clinical practice and may be one of the important causes of chest pain particularly anterior chest wall pain. While reading computed tomography (CT) of the chest for evaluation of chest pain, the sternal region is either easily overlooked or its abnormality is often detected incidentally. This article will provide an overview of normal sternal anatomy and congenital variants as well as a variety of non-tumorous pathologic conditions of the sternum and adjacent joints, with emphasis on CT, to help radiologists, particularly thoracic radiologists, to make an accurate diagnosis in their daily practice.

Beyond Pulmonary Embolism; Nonthrombotic Pulmonary Embolism as Diagnostic Challenges.

Nonthrombotic pulmonary embolism (NTPE) is less well understood and is encountered less frequently than pulmonary embolism from venous thrombosis. NTPE results from embolization of nonthrombotic material to the pulmonary vasculature originating from many different cell types as well as nonbiologic or foreign materials. For many radiologists NTPE is a challenging diagnosis, presenting nonspecific or unusual imaging findings in the setting of few or unusual clinical signs.

Variability of Tear Osmolarity in Patients With Dry Eye.

Importance: Knowledge about the variability of measurements using the TearLab Osmolarity System is necessary when evaluating the clinical utility of readings.

Objective: To examine the variability of tear osmolarity measured by the TearLab Osmolarity System in patients with Sjögren syndrome (SS), patients with blepharitis, and control participants.

Design, Setting, And Participants: Cross-sectional study at a tertiary care academic center from June 13, 2012, to March 21, 2013.
