Development and Prospective Validation of a Machine Learning-Based Risk of Readmission Model in a Large Military Hospital.

Background: Thirty-day hospital readmissions are a quality metric for health care systems. Predictive models aim to identify patients likely to readmit to more effectively target preventive strategies. Many risk of readmission models have been developed on retrospective data, but prospective validation of readmission models is rare.

Could Nonenhanced Computer Tomography Suffice as the Imaging Study of Choice for the Screening of Asymptomatic Microscopic Hematuria?

Objective: To compare the diagnostic accuracy of the noncontrast and contrast-enhanced phases of computed tomographic urography for detection of upper urinary tract findings in adults undergoing initial evaluation of newly diagnosed asymptomatic microscopic hematuria to determine if less-intensive noncontrast imaging has the potential to become a suitable imaging alternative in the work-up of this common condition.

Materials And Methods: Retrospective review from 2010-2015 for adults who underwent computed tomographic urography for initial evaluation of asymptomatic microscopic hematuria. Three nonblinded physicians independently categorized the upper urinary tract findings described in the computed tomography reports into one of three groups: normal, benign, or suspicious for malignancy.

The role of whole-body magnetic resonance imaging in diagnosing chronic recurrent multifocal osteomyelitis.

Chronic recurrent multifocal osteomyelitis (CRMO) is an uncommon idiopathic inflammatory disorder. The diagnosis is often delayed because a variable clinical presentation and limited awareness among care providers. We present an 11-year-old female diagnosed with CRMO and her imaging workup.

Testicular hemangioma mimicking a malignant neoplasm.

A 34-year-old man who presented with right scrotal pain, and who on subsequent ultrasound examination, was found to have an intratesticular hypoechoic mass. Based on the ultrasound appearance of this mass, a malignant germ cell tumor was thought to be the most likely diagnosis. Preoperative serum tumor markers, including lactate dehydrogenase, alpha-1-fetoprotein, and beta-human chorionic gonadotropin, were negative.

Spontaneous mediastinal haematoma: a rare complication of warfarin therapy.

A 64-year-old woman presented with shortness of breath, right-sided pleuritic chest pain and dry cough. She was systemically anticoagulated with warfarin for a pulmonary embolism diagnosed 3 months previously, with an international normalised ratio (INR) of 3.0 on presentation.
