When is endoscopy used? Endoscopes were first developed to look at parts of the body that couldn’t be seen any other way. This is still a common reason to use them, but endoscopy now has many other uses too. It’s often used in the prevention, early detection, diagnosis, staging, and treatment of cancer. To prevent and screen for cancer Some types of endoscopes are used to look for cancer in people who have no symptoms. For example, colonoscopy (KO-lun-AH-skuh-pee) and sigmoidoscopy (SIG-moid-AH-skuh-pee) are used to screen for colon and rectal cancer. These procedures can also help prevent cancer because they let doctors find and remove polyps (growths) that might become cancer if left alone. To find cancer early Endoscopy can sometimes be used to find cancer early, before it has had a chance to grow or spread. Looking for causes of symptoms When people go to the doctor with certain symptoms, endoscopy can sometimes be used to help find a cause. For instance: Laryngoscopy to look at the vocal cords in people with long-term hoarseness Upper endoscopy in people having trouble swallowing Colonoscopy in people with anemia (low red blood cell counts) with an unknown cause Colonoscopy in people with blood in their stool Looking at problems found on imaging tests Imaging tests such as x-rays and CT scans can sometimes show physical changes within the body. But these tests may only give information about the size, shape, and location of the problem. Doctors use endoscopes to see more details, like color and surface texture, when trying to find out what’s going on. Newer methods of endoscopy that include high magnification are being tested to find out whether they are more useful in detecting cancer and other abnormal cells on the inner surfaces of the body. To diagnose and find out the stage (extent) of cancer To get a tissue sample Going one step further, most types of endoscopes have tools on the end that the doctor can use to take out small tissue samples. This procedure is called a biopsy (BY-op-see). Samples can be taken from suspicious areas and then looked at under a microscope or tested in other ways to see if cancer is there. A biopsy is usually the best way to find out if a growth or change is cancer or something else. Getting a closer look In some cases endoscopes are used to help find out how far a cancer has spread. Thoracoscopy (THOR-uh-KAHS -kuh-pee) and laparoscopy (LAP-uh-RAHS-kuh-pee) can be very useful in finding out if cancer has spread into the thorax (chest) or abdomen (belly). The surgeon can look into these places making only a small incision (cut) in the skin.

Every 10 minutes, someone is added to the national transplant waiting list, and every day, 22 people on average die waiting for a match, according to the United Network for Organ Sharing. But, thanks to innovations in bioengineering, all of that could change. Conceived nearly 60 years ago, the total artificial heart (TAH) has helped sustain the sickest biventricular failure patients waiting for a transplant. While the design of the primary TAH used today has mostly remained stagnant since the ’80s, when it was first implanted in a patient, new models and clinical trials may lead to a better device and, one day, a permanent solution. “We are still many years away from that,” Dr. Nader Moazami, director of the Cardiac Transplantation and Ventricular Assist Device Therapy Program at the Cleveland Clinic, told FoxNews.com of a permanent artificial heart. “Although tremendous strides have been made, biocompatibility will always remain a challenge.”

The accumulation of ascitic fluid represents a state of total-body sodium and water excess, but the event that initiates the unbalance is unclear. Although many pathogenic processes have been implicated in the development of abdominal ascites, about 75% likely occur as a result of portal hypertension in the setting of liver cirrhosis, with the remainder due to infective, inflammatory, and infiltrative conditions. Three theories of ascites formation have been proposed: underfilling, overflow, and peripheral arterial vasodilation. The underfilling theory suggests that the primary abnormality is inappropriate sequestration of fluid within the splanchnic vascular bed due to portal hypertension and a consequent decrease in effective circulating blood volume. This activates the plasma renin, aldosterone, and sympathetic nervous system, resulting in renal sodium and water retention. The overflow theory suggests that the primary abnormality is inappropriate renal retention of sodium and water in the absence of volume depletion. This theory was developed in accordance with the observation that patients with cirrhosis have intravascular hypervolemia rather than hypovolemia. The most recent theory, the peripheral arterial vasodilation hypothesis, includes components of both of the other theories. It suggests that portal hypertension leads to vasodilation, which causes decreased effective arterial blood volume. As the natural history of the disease progresses, neurohumoral excitation increases, more renal sodium is retained, and plasma volume expands. This leads to overflow of fluid into the peritoneal cavity. The vasodilation theory proposes that underfilling is operative early and overflow is operative late in the natural history of cirrhosis. Although the sequence of events that occurs between the development of portal hypertension and renal sodium retention is not entirely clear, portal hypertension apparently leads to an increase in nitric oxide levels. Nitric oxide mediates splanchnic and peripheral vasodilation. Hepatic artery nitric oxide synthase activity is greater in patients with ascites than in those without ascites. Regardless of the initiating event, a number of factors contribute to the accumulation of fluid in the abdominal cavity. Elevated levels of epinephrine and norepinephrine are well-documented factors. Hypoalbuminemia and reduced plasma oncotic pressure favor the extravasation of fluid from the plasma to the peritoneal fluid, and, thus, ascites is infrequent in patients with cirrhosis unless both portal hypertension and hypoalbuminemia are present.

X-linked adrenoleukodystrophy is a genetic disorder that occurs primarily in males. It mainly affects the nervous system and the adrenal glands, which are small glands located on top of each kidney. In this disorder, the fatty covering (myelin) that insulates nerves in the brain and spinal cord is prone to deterioration (demyelination), which reduces the ability of the nerves to relay information to the brain. In addition, damage to the outer layer of the adrenal glands (adrenal cortex) causes a shortage of certain hormones (adrenocortical insufficiency). Adrenocortical insufficiency may cause weakness, weight loss, skin changes, vomiting, and coma.

Pigmentflecken, Vitiligo Komplett Geheilt, Pigmentflecken Oberlippe, Vitiligo Heilung, Vitiligo--- http://vitiligo-heilung.info-pro.co/ --- Was ist Vitiligo? Vitiligo ist ein medizinischer Zustand, der die Haut befällt. Die Haut entwickelt dabei an unterschiedlichen Körperstellen nach und nach weiße Flecken, weshalb die Hautstörung im Deutschen auch als "Weißfleckenkrankheit" bekannt ist. Vitiligo macht keine Unterschiede bei Geschlecht oder Rasse und kann jeden befallen. Es wird geschätzt, dass gegenwärtig mehr als 100 Millionen Menschen weltweit in mehr oder minderem starken Maße an Vitiligo leiden. In den Vereinigten Staaten ist die Prävalenzrate etwa 1 % der Bevölkerung; Europa weist ähnliche Raten auf. Was verursacht den Zustand? Vitiligo tritt auf, wenn die Melanozyten in der Haut aus irgendeinem Grund zerstört werden oder ihre Funktion einstellen. Als Melanozyten bezeichnet man jene Hautzellen, die für die Hautfarbe verantwortlich sind. Werden sie zerstört oder anderweitig kompromittiert, stellen produzieren sie kein Melanin mehr, das Hautpigment. Das führt dann zu weißen Hautflecken. Es gibt verschiedene Faktoren, welche die Melanozyten zerstören oder beeinträchtigen können. Dennoch bleibt die Ursache bei den meisten Fällen von Vitiligo ungeklärt. Es wird außerdem angenommen, dass es sich bei Vitiligo um eine Autoimmunerkrankung handelt, welche das Immunsystem die Melanozyten angreifen lässt. Vitiligo kann zudem das Resultat einer Melanozytenstörung sein, welche diese Zellen praktisch veranlasst, "Sebstmord" zu begehen. Laut mancher Forscher kann Vitiligo aber auch durch chronischen Stress und Sonnenbrand hervorgerufen werden. Was sind die Symptome? Das offensichtlichste Symptom von Vitiligo sind die weißen Hautflecken, die sich im Laufe der Zeit vergrößern und auch weiter ausbreiten können. Die Rate, mit der die Hautstörung voranschreitet, unterscheidet sich dabei von Patient zu Patient. "Gratis-Präsentation enthüllt einen ziemlich ungewöhnlichen Tipp zur Beseitigung von Vitiligo für alle Zeiten und in nur 45-60 Tagen - Garantiert!" http://vitiligo-heilung.info-pro.co
