Situs Inversus
Situs Inversus samer kareem 7,220 Views • 3 years ago

Situs inversus is a condition in which the arrangement of the internal organs is a mirror image of normal anatomy. It can occur alone (isolated, with no other abnormalities or conditions) or it can occur as part of a syndrome with various other defects. Congenital heart defects are present in about 5-10% of affected people. The underlying cause and genetics of situs inversus are complex. Familial cases have been reported.[1][2]

Spleen
Spleen samer kareem 5,355 Views • 3 years ago

The spleen, a spongy, soft organ about as big as a person’s fist, is located in the upper left part of the abdomen, just under the rib cage. The splenic artery brings blood to the spleen from the heart. Blood leaves the spleen through the splenic vein, which drains into a larger vein (the portal vein) that carries the blood to the liver. The spleen has a covering of fibrous tissue (the splenic capsule) that supports its blood vessels and lymphatic vessels. The spleen is made up of two basic types of tissue, each with different functions: White pulp Red pulp The white pulp is part of the infection-fighting (immune) system. It produces white blood cells called lymphocytes, which in turn produce antibodies (specialized proteins that protect against invasion by foreign substances). The red pulp filters the blood, removing unwanted material. The red pulp contains other white blood cells called phagocytes that ingest microorganisms, such as bacteria, fungi, and viruses. It also monitors red blood cells, destroying those that are abnormal or too old or damaged to function properly. In addition, the red pulp serves as a reservoir for different elements of the blood, especially white blood cells and platelets (cell-like particles involved in clotting). However, releasing these elements is a minor function of the red pulp.

Hodgkin's lymphoma
Hodgkin's lymphoma samer kareem 5,887 Views • 3 years ago

Hodgkin's lymphoma — formerly known as Hodgkin's disease — is a cancer of the lymphatic system, which is part of your immune system. In Hodgkin's lymphoma, cells in the lymphatic system grow abnormally and may spread beyond the lymphatic system. As Hodgkin's lymphoma progresses, it compromises your body's ability to fight infection. Hodgkin's lymphoma is one of two common types of cancers of the lymphatic system. The other type, non-Hodgkin's lymphoma, is far more common. Advances in diagnosis and treatment of Hodgkin's lymphoma have helped give people with this diagnosis the chance for a full recovery. The prognosis continues to improve for people with Hodgkin's lymphoma.

Hip Replacement
Hip Replacement samer kareem 3,784 Views • 3 years ago

On September 28, 1940 at Columbia Hospital in Columbia, South Carolina, Dr. Austin T. Moore (1899–1963), an American surgeon, reported and performed the first metallic hip replacement surgery. In a total hip replacement (also called total hip arthroplasty), the damaged bone and cartilage is removed and replaced with prosthetic components. The damaged femoral head is removed and replaced with a metal stem that is placed into the hollow center of the femur.

Leg Vein Valve
Leg Vein Valve samer kareem 7,067 Views • 3 years ago

The deep veins play a significant role in propelling blood toward the heart. The one-way valves in deep veins prevent blood from flowing backward, and the muscles surrounding the deep veins compress them, helping force the blood toward the heart, just as squeezing a toothpaste tube ejects toothpaste.

Prenatal Repair of Spina Bifida samer kareem 2,561 Views • 3 years ago

Repairing a myelomeningocele in utero, rather than after birth, reduces the risk for fetal or neonatal death and the need for shunting by age 1 and substantially improves neurologic and motor outcomes. However, it is not without maternal and fetal risks. These are the findings, in a nutshell, of the long-awaited Management of Myelomeningocele Study (MOMS), which were published online February 9 in The New England Journal of Medicine.

Reactive Arthritis Causes
Reactive Arthritis Causes samer kareem 1,615 Views • 3 years ago

Reactive arthritis is a painful form of inflammatory arthritis (joint disease due to inflammation). It occurs in reaction to an infection by certain bacteria. Most often, these bacteria are in the genitals (Chlamydia trachomatis) or the bowel (Campylobacter, Salmonella, Shigella and Yersinia). Chlamydia most often transmits by sex. It often has no symptoms, but can cause a pus-like or watery discharge from the genitals. The bowel bacteria can cause diarrhea. If you develop arthritis within one month of diarrhea or a genital infection – especially with a discharge – see a health care provider. You may have reactive arthritis. - See more at: https://www.rheumatology.org/i-am-a/patient-caregiver/diseases-conditions/reactive-arthritis#sthash.PukaaQhj.dpuf
