Idiopathic granulomatous lobular mastitis.

Idiopathic granulomatous lobular mastitis (IGLM) is a rare breast condition with prominent skin findings. It is typically seen in young parous women. Painful breast masses, draining sinuses, scarring, and breast atrophy are the main clinical manifestations.

Superantigens in dermatology.

Superantigens (SAgs) are virulent polypeptides that are produced by a variety of infectious organisms. They are capable of causing nonspecific T cell activation by circumventing normal antigen processing in the human host. The genetic makeup of the host plays a role in conferring susceptibility or protection against SAgs.

Intracellular calcium dynamics and anisotropic reentry in isolated canine pulmonary veins and left atrium.

Background: Rapid activations due to either focal discharge or reentry are often present during atrial fibrillation (AF) in the pulmonary veins (PVs). The mechanisms of these rapid activations are unclear.

Methods And Results: We studied 7 isolated, Langendorff-perfused canine left atrial (LA) and PV preparations and used 2 cameras to map membrane potential alone (Vm, n=3) or Vm and intracellular calcium simultaneously (Ca(i), n=4).
