Burden of coronary artery calcification in ANCA-associated vasculitis.

Background: Cardiovascular disease (CVD) is a leading cause of death in ANCA-associated vasculitis (AAV). Screening and primary cardiovascular prevention may improve outcomes.

Methods: We identified patients in the 2002-2019 Mass General Brigham AAV cohort with thoracic CT scans obtained for other clinical purposes.

Optical coherence tomography angiography enables visualization of microvascular patterns in chronic venous insufficiency.

Chronic venous insufficiency (CVI) is a global health concern with significant public health and individual impact. Currently available diagnostic methods cannot visualize microvenous pathologies that have shown to result in severe forms of CVI and also affect the skin. Optical coherence tomography angiography (OCTA) may close the CVI diagnostic gap by providing a fast, label-free, and non-invasive solution to visualize cutaneous microvasculature.

Are Patch Testing Reactions Underrecognized in Skin of Color? Evaluating the Frequency of Borderline Reactions by Fitzpatrick Skin Type.

Patch testing reactions can be difficult to interpret in patients with skin of color (higher Fitzpatrick skin types [FSTs]) due to limited erythema or vesiculation. Missed reactions may lead to prolonged allergic contact dermatitis duration and prevent disease clearance in this population. To compare the frequency of borderline patch test reactions in patients with different FSTs (I, II, III, IV, V, VI).

Panthenol Allergic Contact Dermatitis: Sources of Exposure, Reported Cases, and a Call for More Frequent Testing.

Panthenol, a vitamin B5 derivative, is a key precursor in the synthesis of fatty acids that maintain epithelial function. Its ability to aid in moisturization, skin barrier restoration, and wound healing has led to its frequent incorporation into personal care products and pharmaceuticals-many of which are marketed to be hypoallergenic. While contact allergy to panthenol is rather uncommon, rates of positive reactions are on the rise, increasing from 0.

Transcranial Cortex-Wide Imaging of Murine Ischemic Perfusion With Large-Field Multifocal Illumination Microscopy.

Background: Ischemic stroke is a common cause of death worldwide and a main cause of morbidity. Presently, laser speckle contrast imaging, x-ray computed tomography, and magnetic resonance imaging are the mainstay for stroke diagnosis and therapeutic monitoring in preclinical studies. These modalities are often limited in terms of their ability to map brain perfusion with sufficient spatial and temporal resolution, thus calling for development of new brain perfusion techniques featuring rapid imaging speed, cost-effectiveness, and ease of use.
