Ectropion (ek-TROH-pee-on) is a condition in which your eyelid turns outward. This leaves the inner eyelid surface exposed and prone to irritation.

Ectropion is more common in older adults, and it generally affects only the lower eyelid. In severe ectropion, the entire length of the eyelid is turned out. In less severe ectropion, only one segment of the eyelid sags away from the eye. | #Ectropion

Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of your heart's two lower pumping chambers (ventricles). These extra beats disrupt your regular heart rhythm, sometimes causing you to feel a fluttering or a skipped beat in your chest.

Premature ventricular contractions are common — they occur in many people. | #Pvc

Ebstein anomaly is a rare heart defect that's present at birth (congenital). In this condition, your tricuspid valve is in the wrong position and the valve's flaps (leaflets) are malformed. As a result, the valve does not work properly.

Blood might leak back through the valve, making your heart work less efficiently. Ebstein anomaly can also lead to enlargement of the heart and heart failure | #Ebstein anomaly

Ebola virus and Marburg virus are related viruses that may cause hemorrhagic fevers. These are marked by severe bleeding (hemorrhage), organ failure and, in many cases, death. Both viruses are native to Africa, where sporadic outbreaks have occurred for decades.

Ebola virus and Marburg virus live in animal hosts. Humans can get the viruses from infected animals. After the initial transmission, the viruses can spread from person to person through contact with body fluids or unclean items such as infected needles | #Ebola and Marburg

Binge-eating disorder is a serious eating disorder in which you frequently consume unusually large amounts of food and feel unable to stop eating.

Almost everyone overeats on occasion, such as having seconds or thirds of a holiday meal. But for some people, excessive overeating that feels out of control and becomes a regular occurrence crosses the line to binge-eating disorder. | #Binge eating
