Diaphragmatic muscle thickness and diaphragmatic function are reduced in patients with systemic lupus erythematosus compared to those with primary Sjögren's syndrome.

Introduction: Systemic lupus erythematosus (SLE) is associated with an increased risk of pulmonary infections, as well as a rare condition known as shrinking lung syndrome (SLS). The diaphragm has an important role to play in lung physiology and might also play a role in these adverse events. Here, we aimed to investigate whether SLE patients have impairment in their diaphragmatic muscle thickness and function with respect to another connective-tissue disease: primary Sjögren's syndrome (pSS).

Interobserver variability and stiffness measurements of normal common extensor tendon in healthy volunteers using shear wave elastography.

Objectives: The purposes of our study are to determine the quantitative elasticity values of normal common extensor tendon (CET) and to assess the interobserver variability of stiffness measurements using shear wave elastography (SWE).

Materials And Methods: A total of 60 CETs of 30 (15 female, 15 male, mean age 30.2 years) healthy volunteers without any symptoms of lateral epicondylitis were examined by two radiologists.
