Tonsillectomy (ton-sih-LEK-tuh-me) is the surgical removal of the tonsils, two oval-shaped pads of tissue at the back of the throat — one tonsil on each side. A tonsillectomy was once a common procedure to treat infection and inflammation of the tonsils (tonsillitis). Today, a tonsillectomy is usually performed for sleep-disordered breathing but may still be a treatment when tonsillitis occurs frequently or doesn't respond to other treatments. A tonsillectomy may also be necessary to treat breathing and other problems related to enlarged tonsils and to treat rare diseases of the tonsils.
As the liver becomes more severely damaged, more obvious and serious symptoms can develop, such as: yellowing of the skin and whites of the eyes (jaundice) swelling in the legs, ankles and feet, due to a build-up of fluid (oedema) swelling in your abdomen, due to a build-up of fluid known as ascites.
Before Dr. Benjamin Carson became the first person to successfully separate twins conjoined at the head, before he had a TV movie made about his life, before he became known for his "gifted hands" and before he became head of pediatric neurosurgery at Johns Hopkins, Ben Carson was headed down the wrong path in life.
Gallstone ileus is an important, though infrequent, cause of mechanical bowel obstruction, affecting older adult patients who often have other significant medical conditions. It is caused by impaction of a gallstone in the ileum after being passed through a biliary-enteric fistula. The diagnosis is often delayed since symptoms may be intermittent and investigations fail to identify the cause of the obstruction. The mainstay of treatment is removal of the obstructing stone after resuscitating the patient. Gallstone ileus continues to be associated with relatively high rates of morbidity and mortality.
Breast Cancer spreads by 3 mechanisms- local spread, by lymph nodes, or through the blood. Dr. Lorraine Champion, and Dr. Lisa Bailey discuss how breast cancer spreads. They discuss the different methods of spread and how this will affect the treatment of breast cancer.
A pilonidal sinus (PNS) is a small cyst or abscess that occurs in the cleft at the top of the buttocks. A PNS usually contains hair, dirt, and debris. It can cause severe pain and can often become infected. If it becomes infected, it may ooze pus and blood and have a foul odor. A PNS is a condition that mostly affects men and is also common in young adults. It’s also more common in people who sit a lot, like cab drivers.
The majority of fetuses are in a breech presentation early in pregnancy. By week 38th week of gestation, however, the fetus normally turns to a cephalic presentation. Although the fetal head is the widest single diameter, the fetus’s buttocks [ breech], plus the lower extremities, actually takes up more space. The fundus, being the largest part of the uterus, probably accounts for the fact that in approximately 97% of all pregnancies, the fetus turns so that the buttocks and lower extremities are in the fundus. Vaginal delivery of a breech presentation requires great skill if the fetus is not to be damaged. With the low rate of vaginal breech deliveries in the developed world, experience is being lost. 6% of women with breech presentation still have a vaginal breech delivery as they present too late - so units need to retain a high level of preparedness. Types of breech presentation: I. Complete breech [ flexed breech]: The fetal attitude is one of complete flexion, with hips and knees both flexed and the feet tucked in beside the buttocks. The presenting part consists of two buttocks, external genitalia and two feet. It is commonly present in multiparae. II. Incomplete breech: This is due to varying degrees of extension of thighs or legs at podalic pole. Three varieties are possible; - Breech with extended legs [ frank breech ]: The breech presents with the hips flexed and legs extended on the abdomen. 70% of breech presentations are of this type and it is particularly common in primigravidae whose good uterine muscle tone inhibits flexion of the legs and free turning of the fetus. - Footling breech: This is rare. One or both feet present because neither hips nor knees are fully flexed. The feet are lower than the buttocks, which distinguishes it from the complete breech. - Knee presentation: This is very rare. Thighs are extended but the knees are flexed, bringing the knees down to present at the brim.
To understand high blood cholesterol (ko-LES-ter-ol), it helps to learn about cholesterol. Cholesterol is a waxy, fat-like substance that’s found in all cells of the body. Your body needs some cholesterol to make hormones, vitamin D, and substances that help you digest foods. Your body makes all the cholesterol it needs. However, cholesterol also is found in some of the foods you eat. Cholesterol travels through your bloodstream in small packages called lipoproteins (lip-o-PRO-teens). These packages are made of fat (lipid) on the inside and proteins on the outside. Two kinds of lipoproteins carry cholesterol throughout your body: low-density lipoproteins (LDL) and high-density lipoproteins (HDL). Having healthy levels of both types of lipoproteins is important. LDL cholesterol sometimes is called “bad” cholesterol. A high LDL level leads to a buildup of cholesterol in your arteries. (Arteries are blood vessels that carry blood from your heart to your body.) HDL cholesterol sometimes is called “good” cholesterol. This is because it carries cholesterol from other parts of your body back to your liver. Your liver removes the cholesterol from your body.
