Hirschsprung's Disease
Hirschsprung's Disease samer kareem 10,975 Views • 3 years ago

Hirschsprung's (HIRSH-sproongz) disease is a condition that affects the large intestine (colon) and causes problems with passing stool. The condition is present at birth (congenital) as a result of missing nerve cells in the muscles of the baby's colon. A newborn who has Hirschsprung's disease usually can't have a bowel movement in the days after birth. In mild cases, the condition might not be detected until later in childhood. Uncommonly, Hirschsprung's disease is first diagnosed in adults.

A V FISTULA GRAFT
A V FISTULA GRAFT samer kareem 1,910 Views • 3 years ago

arteriovenous hemodialysis access has been the "gold standard" for patients needing hemodialysis for the past 30 years. Despite the reported advantages of autologous access, the availability of prosthetic graft material, coupled with the challenging dialysis candidate, has led to a trend of primary prosthetic graft dialysis access in the 1980s and 1990s. In recognition of this unfortunate trend, the National Kidney Foundation Dialysis Outcomes Quality Initiative (DOQI) used evidence from published studies and summary articles to generate clinical practice guidelines, emphasizing a shift back to autologous arteriovenous fistula (AVF) as the key to long-term successful hemodialysis.[1,2] These initial guidelines proposed a goal of 50% autologous AVF as the initial access, with a 40% prevalence of autologous access for a given practice or unit.

The development of the gastrointestinal tract
The development of the gastrointestinal tract samer kareem 2,554 Views • 3 years ago

The gastrointestinal tract (GIT) arises initially during the process of gastrulation from the endoderm of the trilaminar embryo (week 3) and extends from the buccopharyngeal membrane to the cloacal membrane. The tract and associated organs later have contributions from all the germ cell layers. During the 4th week three distinct regions (fore-, mid- and hind-gut) extend the length of the embryo and will contribute different components of the GIT. The large mid-gut is generated by lateral embryonic folding which "pinches off" a pocket of the yolk sac, the 2 compartments continue to communicate through the vitelline duct. The oral cavity (mouth) is formed following breakdown of the buccopharyngeal membrane (oropharyngeal or oral membrane) and contributed to mainly by the pharynx lying within the pharyngeal arches (More? Head Development). Loss of buccopharyngeal membrane opens the tract to amniotic fluid through the remainder of development, and during the fetal period is actively swallowed.

Tonsillitis
Tonsillitis samer kareem 2,432 Views • 3 years ago

Tonsillitis is inflammation of the tonsils, two oval-shaped pads of tissue at the back of the throat — one tonsil on each side. Signs and symptoms of tonsillitis include swollen tonsils, sore throat, difficulty swallowing and tender lymph nodes on the sides of the neck. Most cases of tonsillitis are caused by infection with a common virus, but bacterial infections also may cause tonsillitis. Because appropriate treatment for tonsillitis depends on the cause, it's important to get a prompt and accurate diagnosis. Surgery to remove tonsils, once a common procedure to treat tonsillitis, is usually performed only when bacterial tonsillitis occurs frequently, doesn't respond to other treatments or causes serious complications.

Reyes syndrome
Reyes syndrome samer kareem 2,074 Views • 3 years ago

In Reye's syndrome, a child's blood sugar level typically drops while the levels of ammonia and acidity in his or her blood rise. At the same time, the liver may swell and develop fatty deposits. Swelling may also occur in the brain, which can cause seizures, convulsions or loss of consciousness. The signs and symptoms of Reye's syndrome typically appear about three to five days after the onset of a viral infection, such as the flu (influenza) or chickenpox, or an upper respiratory infection, such as a cold

Spider Vein Sclerotherapy Injections samer kareem 1,722 Views • 3 years ago

Sclerotherapy is a medical procedure used to eliminate varicose veins and spider veins. Sclerotherapy involves an injection of a solution (generally a salt solution) directly into the vein. The solution irritates the lining of the blood vessel, causing it to collapse and stick together and the blood to clot.

Varicose Veins: samer kareem 5,231 Views • 3 years ago

Varicose veins are caused by weakened valves and veins in your legs. Normally, one-way valves in your veins keep blood flowing from your legs up toward your heart. When these valves do not work as they should, blood collects in your legs, and pressure builds up. The veins become weak, large, and twisted.

Diverticulitis
Diverticulitis samer kareem 2,411 Views • 3 years ago

Diverticula are small, bulging pouches that can form in the lining of your digestive system. They are found most often in the lower part of the large intestine (colon). Diverticula are common, especially after age 40, and seldom cause problems. Sometimes, however, one or more of the pouches become inflamed or infected. That condition is known as diverticulitis (die-vur-tik-yoo-LIE-tis). Diverticulitis can cause severe abdominal pain, fever, nausea and a marked change in your bowel habits. Mild diverticulitis can be treated with rest, changes in your diet and antibiotics. Severe or recurring diverticulitis may require surgery.
