Portal Hypertension
Portal Hypertension samer kareem 9,195 Views • 2 years ago

Portal hypertension is an increase in the blood pressure within a system of veins called the portal venous system. Veins coming from the stomach, intestine, spleen, and pancreas merge into the portal vein, which then branches into smaller vessels and travels through the liver.

Ovarian teratoma is a type of germ cell tumour. Germ cell tumours are cancers that begin in egg cells in women or sperm cells in men. There are 2 main types of ovarian teratoma. Mature teratoma, which is benign. Immature teratoma, which is cancerous.

An appendectomy (sometimes called appendisectomy or appendicectomy) is the surgical removal of the vermiform appendix. This procedure is normally performed as an emergency procedure, when the patient is suffering from acute appendicitis.

Endometrial Polyp
Endometrial Polyp samer kareem 20,642 Views • 2 years ago

Uterine polyps are growths attached to the inner wall of the uterus that extend into the uterine cavity. Overgrowth of cells in the lining of the uterus (endometrium) leads to the formation of uterine polyps, also known as endometrial polyps. These polyps are usually noncancerous (benign), although some can be cancerous or can eventually turn into cancer (precancerous polyps). Uterine polyps range in size from a few millimeters — no larger than a sesame seed — to several centimeters — golf-ball-size or larger. They attach to the uterine wall by a large base or a thin stalk.

Signs and symptoms of bone cancer samer kareem 1,644 Views • 2 years ago

Pain in the affected bone is the most common complaint of patients with bone cancer. At first, the pain is not constant. It may be worse at night or when the bone is used (for example, leg pain when walking). As the cancer grows, the pain will be there all the time. The pain increases with activity and the person might limp if a leg is involved.

Familial Hypocalciuric Hypercalcemia
Familial Hypocalciuric Hypercalcemia samer kareem 4,340 Views • 2 years ago

There are 3 genetic types of FHH based on chromosome location. FHH type 1 accounts for 65% of cases and is due to inactivating mutations in the CASR gene, localized to 3q21.1. This gene encodes the calcium-sensing receptor (CaSR). Loss of CaSR function results in a reduction in the sensitivity of parathyroid and renal cells to calcium levels so hypercalcemia is perceived as normal. The other 35% have either a mutation GNA11 (19p13.3) seen in FHH type 2 or AP2S1 (19q13.2-q13.3) seen in FHH type 3 (see these terms) or in genes not yet discovered. FHH is rarely caused by auto-antibodies against CaSR in those without a mutation.

Insulin, Glucose and you
Insulin, Glucose and you samer kareem 2,606 Views • 2 years ago

Insulin is a hormone made naturally in the pancreas that helps move sugar into the cells of your body. Your cells use the sugar as fuel to make energy. Without enough insulin, sugar stays in your bloodstream, raising your blood sugar. High blood sugar, or hyperglycemia, can lead to the signs and symptoms of diabetes:

Lumbar Epidural Abscess
Lumbar Epidural Abscess samer kareem 10,969 Views • 2 years ago

An epidural abscess is a collection of pus (infected material) between the outer covering of the brain and spinal cord and the bones of the skull or spine. The abscess causes swelling in the area. Spinal cord abscess (SCA) is a rare condition capable of causing permanent damage to the spinal cord. Abscesses are caused when injured tissue becomes infected. The body's immune system sends white blood cells to help fight off the infection. They begin to fill the damaged tissue, causing pus to build up.

Acute Intermittent Porphyria
Acute Intermittent Porphyria samer kareem 10,126 Views • 2 years ago

Acute intermittent porphyria (AIP) is a rare autosomal dominant metabolic disorder affecting the production of heme, the oxygen-binding prosthetic group of hemoglobin. It is characterized by a deficiency of the enzyme porphobilinogen deaminase.

ADENOMYOSIS
ADENOMYOSIS samer kareem 22,906 Views • 2 years ago

Adenomyosis is a condition in which the inner lining of the uterus (the endometrium) breaks through the muscle wall of the uterus (the myometrium). Adenomyosis can cause menstrual cramps, lower abdominal pressure, and bloating before menstrual periods and can result in heavy periods.

Immunity System Attacking The Sperms Inside Woman's Body samer kareem 121,143 Views • 2 years ago

An antisperm antibody test looks for special proteins (antibodies) that fight against a man's sperm in blood, vaginal fluids, or semen. The test uses a sample of sperm and adds a substance that binds only to affected sperm. Semen can cause an immune system response in either the man's or woman's body. The antibodies can damage or kill sperm. If a high number of sperm antibodies come into contact with a man's sperm, it may be hard for the sperm to fertilize an egg. The couple has a hard time becoming pregnant. This is called immunologic infertility.

Sound waves enter the ear canal and make the ear drum vibrate. This action moves the tiny chain of bones (ossicles – malleus, incus, stapes) in the middle ear. The last bone in this chain 'knocks' on the membrane window of the cochlea and makes the fluid in the cochlea move.
