Thyroid Disease During Pregnancy
Thyroid Disease During Pregnancy samer kareem 2,351 Views • 2 years ago

Uncontrolled hyperthyroidism during pregnancy can lead to serious health problems in the mother and the unborn baby. During pregnancy, mild hyperthyroidism does not require treatment. More severe hyperthyroidism is treated with antithyroid medications, which act by interfering with thyroid hormone production.

Gastroparesis & Diabetes
Gastroparesis & Diabetes samer kareem 12,783 Views • 2 years ago

Gastroparesis is a disorder affecting people with both type 1 and type 2 diabetes in which the stomach takes too long to empty its contents (delayed gastric emptying). The vagus nerve controls the movement of food through the digestive tract. If the vagus nerve is damaged or stops working, the muscles of the stomach and intestines do not work normally, and the movement of food is slowed or stopped. Just as with other types of neuropathy, diabetes can damage the vagus nerve if blood glucose levels remain high over a long period of time. High blood glucose causes chemical changes in nerves and damages the blood vessels that carry oxygen and nutrients to the nerves. - See more at: http://www.diabetes.org/living-with-diabetes/complications/gastroparesis.html?referrer=https://www.google.com/#sthash.rTgZiOuM.dpuf

Spleen
Spleen samer kareem 5,353 Views • 2 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.

Cell Membrane
Cell Membrane samer kareem 1,394 Views • 2 years ago

The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.

Inguinal Hernia Surgery
Inguinal Hernia Surgery samer kareem 21,962 Views • 2 years ago

During surgery to repair the hernia, the bulging tissue is pushed back in. Your abdominal wall is strengthened and supported with sutures (stitches), and sometimes mesh. This repair can be done with open or laparoscopic surgery. You and your surgeon can discuss which type of surgery is right for you.

Iris Surgery
Iris Surgery samer kareem 6,828 Views • 2 years ago

Cosmetic iris implants have not been evaluated by any U.S. regulatory agency or tested for safety in clinical trials. While the implants are not approved by the U.S. Food and Drug Administration, it has been reported in the media this month that the surgery is being performed overseas. During iris implant surgery, an artificial iris made of silicone is folded and inserted into a slit that has been cut into the cornea. Then the iris is unfolded and adjusted to cover the natural iris. Local anesthesia is used.

Leg Vein Valve
Leg Vein Valve samer kareem 7,065 Views • 2 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.

Robotic Partial Nephrectomy
Robotic Partial Nephrectomy samer kareem 2,313 Views • 2 years ago

The robotic approach to renal surgery, particularly partial nephrectomy, has some inherent challenges, and some familiarity with the da Vinci robotic system is necessary. The surgeon must gain an understanding of the robotic arm movements and range of motion, especially in relation to the clutch and camera. The advent of robotically assisted prostatectomy in 2001 [23] paved the way for widespread accessibility to the da Vinci robotic unit and its application to renal surgery. Since that time, at least one multi-institutional survey has demonstrated superiority of the robotic approach when compared to laparoscopic for outcomes of blood loss, hospital stay and a substantially shorter warm ischemia time, while maintaining equivalence in positive margin rate, operative time and complications. [11] A transperitoneal approach is most commonly used. Prior abdominal operation is not necessarily a contraindication to this procedure, but access should be approached with regard for previous operation(s) by an experienced team.

Laparoscopic Colectomy
Laparoscopic Colectomy samer kareem 6,171 Views • 2 years ago

On the day of your surgery, your health care team will take you to a preparation room. Your blood pressure and breathing will be monitored. You may receive an antibiotic medication through a vein in your arm. You will then be taken to an operating room and positioned on a table. You'll be given a general anesthesia medication to put you in a sleep-like state so that you won't be aware during your operation. The surgical team will then proceed with your colectomy. Colon surgery may be performed in two ways: Open colectomy. Open surgery involves making a longer incision in your abdomen to access your colon. Your surgeon uses surgical tools to free your colon from the surrounding tissue and cuts out either a portion of the colon or the entire colon. Laparoscopic colectomy. Laparoscopic colectomy, also called minimally invasive colectomy, involves several small incisions in your abdomen. Your surgeon passes a tiny video camera through one incision and special surgical tools through the other incisions. The surgeon watches a video screen in the operating room as the tools are used to free the colon from the surrounding tissue. The colon is then brought out through a small incision in your abdomen. This allows the surgeon to operate on the colon outside of your body. Once repairs are made to the colon, the surgeon reinserts the colon through the incision. The type of operation you undergo depends on your situation and your surgeon's expertise. Laparoscopic colectomy may reduce the pain and recovery time after surgery. But not everyone is a candidate for this procedure. Also, in some situations your operation may begin as a laparoscopic colectomy, but circumstances may force your surgical team to convert to an open colectomy. Once the colon has been repaired or removed, your surgeon will reconnect your digestive system to allow your body to expel waste. Options may include: Rejoining the remaining portions of your colon. The surgeon may stitch the remaining portions of your colon together, creating what is called an anastomosis. Stool then leaves your body as before. Connecting your intestine to an opening created in your abdomen. The surgeon may attach your colon (colostomy) or small intestine (ileostomy) to an opening created in your abdomen. This allows waste to leave your body through the opening (stoma). You may wear a bag on the outside of the stoma to collect stool. This can be permanent or temporary. Connecting your small intestine to your anus. After removing both the colon and the rectum (proctocolectomy), the surgeon may use a portion of your small intestine to create a pouch that is attached to your anus (ileoanal anastomosis). This allows you to expel waste normally, though you may have several watery bowel movements each day. As part of this procedure, you may undergo a temporary ileostomy.

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.
