The Evaluation of Palpable Thigh Nodularity in Vaccination-age Children - Differentiating Vaccination Granulomas from Other Causes.

Palpable thigh nodularity is a relatively frequent indication for imaging of vaccination-age children, with patients often referred by their community physician or general practitioner. Ultrasound (US) is the imaging modality of choice to delineate the abnormality, and we present a number of characteristic findings that permit the radiologist and pediatrician to accurately identify the cause. A retrospective review was performed at the largest children's hospital in a European country between 2015 and 2017 over a 30-month period.

CT-guided Lung Biopsy: Effect of Biopsy-side Down Position on Pneumothorax and Chest Tube Placement.

Background Supine or prone positioning of the patient on the gantry table is the current standard of care for CT-guided lung biopsy; positioning biopsy side down was hypothesized to be associated with lower pneumothorax rate. Purpose To assess the effect of positioning patients biopsy side down during CT-guided lung biopsy on the incidence of pneumothorax, chest drain placement, and hemoptysis. Materials and Methods This retrospective study was performed between January 2013 and December 2016 in a tertiary referral oncology center.

Post-influenzal triazole-resistant aspergillosis following allogeneic stem cell transplantation.

Influenza virus infection is now recognised as a risk factor for invasive pulmonary aspergillosis (IPA). Delays in diagnosis contribute to delayed commencement of antifungal therapy. In addition, the emergence of resistance to first-line triazole antifungal agents puts emphasis on early detection to prevent adverse outcomes.

A prospective study of fungal biomarkers to improve management of invasive fungal diseases in a mixed specialty critical care unit.

Purpose: The diagnosis of invasive fungal diseases (IFD) in critical care patients (CrCP) is difficult. The study investigated the performance of a set of biomarkers for diagnosis of IFD in a mixed specialty critical care unit (CrCU).

Methods: A prospective observational study in patients receiving critical care for ≥7days was performed.

Transseptal transcatheter coil embolization of a symptomatic pulmonary arteriovenous aneurysm in a patient with hereditary hemorrhagic telangiectasia.

An atrial transseptal approach was used for embolization of a pulmonary arteriovenous aneurysm in a 56-year-old man with hereditary hemorrhagic telangiectasia. Two previous attempts at embolization of the aneurysm failed because of an inability to cannulate the feeding vessel. A transseptal puncture was performed to gain access to the left superior pulmonary vein allowing retrograde cannulation of the venous sac and successful coiling of the aneurysm without complications.
