Video: Common upper extremity injections utilizing musculoskeletal ultrasound.
The purpose of this video article is to demonstrate the use of ultrasound for upper extremity musculoskeletal injections, covering general guidelines, preprocedure planning, needle selection, and basic technique. Several different upper-extremity injections are shown, including joint injections and aspirations, tendon sheath and bursal injections, and percutaneous treatment of calcific tendinitis. ⋯ Musculoskeletal ultrasound is well suited for imaging-guided injections of the upper extremities. It is readily available, allows for high-resolution real-time imaging of the soft tissues and joints, and is adaptable for patient comfort and positioning. After viewing this video article, the observer should have an understanding of the applications for ultrasound in upper-extremity musculoskeletal interventions and should be able to apply that knowledge to advance their clinical practice.

Prevalence and clinical importance of mesenteric venous thrombosis in the Swiss Inflammatory Bowel Disease Cohort.
The purpose of this study was to evaluate the prevalence of mesenteric venous thrombosis (MVT) in the Swiss Inflammatory Bowel Disease Cohort Study and to correlate MVT with clinical outcome. ⋯ MVT is frequently found in patients with IBD. Among patients with CD, MVT is associated with bowel stenosis and CD-related intestinal surgery.

Ratios of peripheral-to-central airway lumen area and percentage wall area as predictors of severity of chronic obstructive pulmonary disease.
The purpose of this study was to assess the ability of the ratios of peripheral-to-central airway lumen area (hereafter referred to as LA) and percentage wall area (hereafter referred to as %WA) to predict the severity of chronic obstructive pulmonary disease (COPD) according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines. ⋯ Ratios of peripheral-to-central airway LA and %WA show improved correlation with COPD severity.

CT-guided nerve block for pudendal neuralgia: diagnostic and therapeutic implications.
The objective of our study was to help clarify the role of CT-guided pudendal nerve blocks in the problematic and poorly understood entity of pudendal neuralgia (PN). ⋯ CT-guided pudendal nerve blocks appear to be valuable diagnostically for PN and uncommonly therapeutically. On the basis of these preliminary results, we have developed an algorithm for the role of the procedure for PN.
