Normal Heart Sounds
Normal Heart Sounds Scott 67,369 Views • 2 years ago

Normal Heart Sounds With the aid of a stethoscope you can hear the characteristic sounds of the normal heartbeat, typically described as a "lub-dub." These sounds are produced by the closure of the heart valves. The first heart sound or "lub" results from closure of the tricuspid and mitral valves. It is a rather low-pitched and a relatively long sound which, as indicated in, represents the beginning of ventricular systole. The second heart sound, or "dub," marks the beginning of ventricular diastole. It is produced by closure of the aortic and pulmonary (pulmonic) semilunar vanes when the intraventricular pressure begins to fall. This "dub" sound is typically heard as a sharp snap because the semilunar valves tend to close much more rapidly than the AV valves. Because diastole occupies more time than systole, a brief pause occurs after the second heart sound when the heart is beating at a normal rate. Therefore, the pattern that one hears is one of: "lub-dub" pause, "lub-dub" pause, and so on. Sometimes, especially in young normal individuals, a third heart sound can be heard. This sound is produced by the very rapid influx of blood into the partially filled ventricle. It is typically very faint and as such difficult to hear.

Porcelain Gallbladder
Porcelain Gallbladder samer kareem 6,601 Views • 2 years ago

Porcelain gallbladder is a condition characterized by calcium salt deposits in the wall of a chronically inflamed gallbladder. The calcifications can be thin or faintly visible, or may be amorphous, patchy, and thick. The gallbladder is generally large, but its size can vary considerably. Most porcelain gallbladders are associated with gallstones. A plain radiograph generally detects these, but computed tomography (CT) has a higher specificity; therefore, a CT scan is performed to confirm the diagnosis. Due to their high risk of gallbladder carcinoma, all patients with porcelain gallbladder should have an elective cholecystectomy.

Travel during pregnancy samer kareem 1,522 Views • 2 years ago

Airline travel. When you're pregnant, the safest time to travel is during your second trimester (18 to 24 weeks), when your risks for miscarriage and preterm labor are lowest. During your third trimester, it's best to stay within 300 miles of home, in case of sudden changes that need medical attention.

Gestational trophoblastic disease
Gestational trophoblastic disease samer kareem 2,309 Views • 2 years ago

What is gestational trophoblastic disease? Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer, and can spread to other areas of the body. To learn more about how cancers start and spread, see What Is Cancer? Gestational trophoblastic (jeh-STAY-shuh-nul troh-fuh-BLAS-tik) disease (GTD) is a group of rare tumors that involve abnormal growth of cells inside a woman's uterus. GTD does not develop from cells of the uterus like cervical cancer or endometrial (uterine lining) cancer do. Instead, these tumors start in the cells that would normally develop into the placenta during pregnancy. (The term gestational refers to pregnancy.) GTD begins in the layer of cells called the trophoblast (troh-fuh-BLAST) that normally surrounds an embryo. (Tropho- means nutrition, and -blast means bud or early developmental cell.) Early in normal development, the cells of the trophoblast form tiny, finger-like projections known as villi. The villi grow into the lining of the uterus. In time, the trophoblast layer develops into the placenta, the organ that protects and nourishes the growing fetus.

Your stomach must be empty, so you should not eat or drink anything for approximately 8 hours before the examination. Your physician will be more specific about the time to begin fasting depending on the time of day that your test is scheduled. Your current medications may need to be adjusted or avoided. Most medications can be continued as usual. Medication use such as aspirin, Vitamin E, non-steroidal anti-inflammatories, blood thinners and insulin should be discussed with your physician prior to the examination as well as any other medication you might be taking. It is therefore best to inform your physician of any allergies to medications, iodine, or shellfish. It is essential that you alert your physician if you require antibiotics prior to undergoing dental procedures, since you may also require antibiotics prior to ERCP. Also, if you have any major diseases, such as heart or lung disease that may require special attention during the procedure, discuss this with your physician. To make the examination comfortable, you will be sedated during the procedure, and, therefore, you will need someone to drive you home afterward. Sedatives will affect your judgment and reflexes for the rest of the day, so you should not drive or operate machinery until the next day.

WHAT IS BURN DEBRIDEMENT? A burn is damage to body tissues caused by sunlight, heat, fire, electricity, friction, radiation, chemicals, hot water or steam. Burns may become infected. Infected burns and the swelling that happens as a result can cause severe damage to the organs and tissues underneath the burned area by putting pressure on the tissues, nerves, and blood vessels. To allow healthy tissue to heal and to prevent more damage or infection, burned tissue is removed in a procedure called burn debridement. Burn debridement can be done by several different methods. They include surgical, chemical, mechanical, or autolytic tissue removal. Debridement may need to be done multiple times as the burned area heals.
