Stress-related mucosal disease (SRMD) is an acute, erosive gastritis representing conditions ranging from stress-related injury to stress ulcers (1, 2). Stress-related injury is superficial mucosal damage that presents primarily as erosions, whereas stress ulcers are deep, focal mucosal damage penetrating the submucosa with high risk for gastrointestinal bleeding (2, 3). Mucosal damage has been reported to occur during the first 24 hours of hospital admission in 75% to 100% of intensive care unit (ICU) patients (4, 5). Clinically important gastrointestinal bleeding can cause hemodynamic instability and increase the need for red blood cell transfusions (1). Significant bleeding may also increase the length of stay in the ICU and mortality (1).

Uterine polyps, also called endometrial polyps, are usually small, bulb-shaped masses of endometrial tissue attached to the uterus by a stalk. They are soft, as opposed to uterine fibroids, which can grow much bigger and are made of hard muscle.
The dural venous sinuses are spaces between the endosteal and meningeal layers of the dura. They contain venous blood that originates for the most part from the brain or cranial cavity. The sinuses contain an endothelial lining that is continuous into the veins that are connected to them.
Overview
Heart bypass surgery creates a new route, called a bypass, for blood and oxygen to reach the heart.
Heart bypass surgery begins with an incision in the chest, and the breastbone is cut exposing the heart. Next, a portion of the saphenous vein, which is very large, is harvested from the inside of the leg. Pieces of this large vein are used to bypass the blocked coronary arteries, which are arteries that supply blood to the heart. The venous graft is sewn to the aorta, the main artery of the body, and to the affected coronary artery, to bypass the blocked site.
The internal mammary artery from the chest may also be used to bypass a clogged artery.
Several arteries may be bypassed depending on the condition of the heart. After the graft is created, the breastbone and chest are closed.
Red eyes usually are caused by allergy, eye fatigue, over-wearing contact lenses or common eye infections such as pink eye (conjunctivitis). However, redness of the eye sometimes can signal a more serious eye condition or disease, such as uveitis or glaucoma.
Prenatal repair of myelomeningocele (MMC), the most common and severe form of spina bifida, is a delicate surgical procedure where fetal surgeons open the uterus and close the opening in the baby's back while they are still in the womb.
