Tale of fat and fib - cardiac lipoma managed with radiofrequency ablation: A case report.

Background: Cardiac lipoma and lipomatous hypertrophy of interatrial septum (LHIS) are very rare disorders with distinct pathological features. While cardiac lipoma is a well-circumscribed encapsulated tumor of mature adipocytes, LHIS is due to entrapment of fat cells in the interatrial septum during embryogenesis. Although a biopsy is the definitive diagnostic test, these disorders can be differentiated by a cardiac magnetic resonance imaging (MRI).

Fetal-placental inflammation, but not adrenal activation, is associated with extreme preterm delivery.

Objective: Spontaneous labor at term involves the activation of placental corticotropin-releasing hormone and the fetal adrenal axis, but the basis for extreme preterm labor is unknown. Our objective was to determine whether placental corticotropin-releasing hormone is activated in extreme preterm labor.

Study Design: One thousand five hundred six mothers delivering at less than 28 weeks' gestation were enrolled.
