A stress ulcer is a single or multiple mucosal defect which can become complicated by upper gastrointestinal bleeding during the physiologic stress of serious illness.

A brain (cerebral) aneurysm is a bulging, weak area in the wall of an artery that supplies blood to the brain. In most cases, a brain aneurysm causes no symptoms and goes unnoticed. In rare cases, the brain aneurysm ruptures, releasing blood into the skull and causing a stroke. When a brain aneurysm ruptures, the result is called a subarachnoid hemorrhage. Depending on the severity of the hemorrhage, brain damage or death may result. The most common location for brain aneurysms is in the network of blood vessels at the base of the brain called the circle of Willis. What causes a brain aneurysm? A person may inherit the tendency to form aneurysms, or aneurysms may develop because of hardening of the arteries (atherosclerosis) and aging. Some risk factors that can lead to brain aneurysms can be controlled, and others can't. The following risk factors may increase your risk for an aneurysm or, if you already have an aneurysm, may increase your risk of it rupturing: Family history. People who have a family history of brain aneurysms are more likely to have an aneurysm than those who don't. Previous aneurysm. People who have had a brain aneurysm are more likely to have another. Gender. Women are more likely to develop a brain aneurysm or to suffer a subarachnoid hemorrhage. Race. African Americans are more likely than whites to have a subarachnoid hemorrhage. High blood pressure. The risk of subarachnoid hemorrhage is greater in people who have a history of high blood pressure. Smoking. In addition to being a cause of high blood pressure, the use of cigarettes may greatly increase the chances of a brain aneurysm rupturing.

What is Laparoscopic Surgery:
Laparoscopic surgery describes procedures performed using one or multiple small incisions in the abdominal wall in contrast to the larger, normally singular incision of laparotomy. The technique is based around principles of minimally invasive surgery (or minimal access surgery): a large group of modern surgical procedures carried out by entering the body with the smallest possible damage to tissues. In abdominopelvic surgery, minimally invasive surgery is generally treated as synonymous with laparoscopic surgery as are procedures not technically within the peritoneal cavity, such as totally extraperitoneal hernia repair, or extending beyond the abdomen, such as thoraco-laparoscopic esophagectomy. The term laparoscopy is sometimes used interchangeably, although this is often reserved to describe a visual examination of the peritoneal cavity or the purely scopic component of a laparoscopic procedure. The colloquial keyhole surgery is common in non-medical usage.

Surgical Objective of Laparoscopic Surgery:
The objective of a laparoscopic approach is to minimize surgical trauma when operating on abdominal or pelvic structures. When correctly indicated and performed, this can result in smaller scars, reduced postoperative morbidity, shorter inpatient durations, and a faster return to normal activity. For a number of abdominopelvic procedures, a laparoscopic approach is now generally considered to be the gold-standard treatment option.

Developments of Laparoscopic Surgery:
Following a number of smaller-scale applications of minimally invasive techniques to abdominopelvic surgery, laparoscopic surgery became a major part of general surgical practice with the introduction of laparoscopic cholecystectomy in the 1980s and the subsequent pioneering of endoscopic camera technology. This led to the widespread adoption of the technique by the early- to mid-1990s. The portfolio of procedures that can be performed laparoscopically has rapidly expanded with improvements in instruments, imaging, techniques and training — forming a central component of modern surgical practice and cross-specialty curricula [2]. Techniques such as laparoscopically assisted surgery and hand-assisted laparoscopic surgery have allowed the application of laparoscopic techniques to a greater variety of pathology. Single-incision laparoscopic surgery, natural orifice transluminal endoscopic surgery, and minilaparoscopy-assisted natural orifice surgery continue to push forward the applications of minimally invasive abdominopelvic techniques; however, the widespread practice and specific indications for these remain to be fully established. More recently, robotic surgery has been able to build on laparoscopic principles through developments in visualization, ergonomics, and instrumentation.

To understand congenital heart defects, it's helpful to know how a healthy heart works. Your child's heart is a muscle about the size of his or her fist. The heart works like a pump and beats 100,000 times a day. The heart has two sides, separated by an inner wall called the septum. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body. The heart has four chambers and four valves and is connected to various blood vessels. Veins are blood vessels that carry blood from the body to the heart. Arteries are blood vessels that carry blood away from the heart to the body.

A central venous catheter, also called a central line, is a long, thin, flexible tube used to give medicines, fluids, nutrients, or blood products over a long period of time, usually several weeks or more. A catheter is often inserted in the arm or chest through the skin into a large vein.

Pain in joints or any part of body is very unpleasant and annoying experience. It is very common in people those suffering from arthritis. To get an end to all such pains, one can start using Generic Celebrex ( https://www.medexpressrx.com/celebrex-generic.aspx ). Here is a brief detail about this wonderful painkiller.

The heart weighs between 7 and 15 ounces (200 to 425 grams) and is a little larger than the size of your fist. By the end of a long life, a person's heart may have beat (expanded and contracted) more than 3.5 billion times. In fact, each day, the average heart beats 100,000 times, pumping about 2,000 gallons. Your heart is located between your lungs in the middle of your chest, behind and slightly to the left of your breastbone (sternum). A double-layered membrane called the pericardium surrounds your heart like a sac. The outer layer of the pericardium surrounds the roots of your heart's major blood vessels and is attached by ligaments to your spinal column, diaphragm, and other parts of your body. The inner layer of the pericardium is attached to the heart muscle. A coating of fluid separates the two layers of membrane, letting the heart move as it beats. Your heart has 4 chambers. The upper chambers are called the left and right atria, and the lower chambers are called the left and right ventricles. A wall of muscle called the septum separates the left and right atria and the left and right ventricles. The left ventricle is the largest and strongest chamber in your heart. The left ventricle's chamber walls are only about a half-inch thick, but they have enough force to push blood through the aortic valve and into your body.

Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of damage to another organ system, often the kidneys. Preeclampsia usually begins after 20 weeks of pregnancy in a woman whose blood pressure had been normal. Even a slight rise in blood pressure may be a sign of preeclampsia. Left untreated, preeclampsia can lead to serious — even fatal — complications for both you and your baby. If you have preeclampsia, the only cure is delivery of your baby. If you're diagnosed with preeclampsia too early in your pregnancy to deliver your baby, you and your doctor face a challenging task. Your baby needs more time to mature, but you need to avoid putting yourself or your baby at risk of serious complications.

A peritonsillar abscess forms in the tissues of the throat next to one of the tonsils. An abscess is a collection of pus that forms near an area of infected skin or other soft tissue. The abscess can cause pain, swelling, and, if severe, blockage of the throat. If the throat is blocked, swallowing, speaking, and even breathing become difficult. When an infection of the tonsils (known as tonsillitis) spreads and causes infection in the soft tissues, a peritonsillar abscess may result. Peritonsillar abscesses are generally uncommon. When they do occur they are more likely among young adults, adolescents, and older children.
