Dolichocolon
Dolichocolon is an abnormally long large intestine.Dolichocolon - definition from CancerWeb at . It should not be confused with an abnormally wide large intestine, which is called a . Dolichocolon may predispose to abnormal rotation (see ) and interposition between the diaphragm and the liver (see |
Megacolon
Megacolon is an abnormal dilation of the colon (also called the large intestine). This leads to hypertrophy of the colon. The dilation is often accompanied by a paralysis of the peristaltic movements of the bowel. In more extreme cases, the feces consolidate into hard masses inside the colon, called fecalomas (literally, ''fecal tumor''), which can require surgery to be removed. A human colon is considered abnormally enlarged if it has a diameter greater than 12 cm in the cecum (it is usually less than 9 cm), greater than 6.5 cm in the rectosigmoid region and greater than 8 cm for the ascending colon. The transverse colon is usually less than 6 cm in diameter. A megacolon can be either acute or chronic. It can also be classified according to cause. Signs and symptoms External signs and symptoms are constipation of very long duration, abdominal bloating, abdominal tenderness and tympany, abdominal pain, palpation of hard fecal masses and, ...

General Surgery
General surgery is a surgical specialty that focuses on alimentary canal and abdominal contents including the esophagus, stomach, small intestine, large intestine, liver, pancreas, gallbladder, appendix and bile ducts, and often the thyroid gland. They also deal with diseases involving the skin, breast, soft tissue, trauma, peripheral artery disease and hernias and perform endoscopic procedures such as gastroscopy and colonoscopy. Scope General surgeons may sub-specialize into one or more of the following disciplines: Trauma surgery In many parts of the world including North America, Australia and the United Kingdom, the overall responsibility for trauma care falls under the auspices of general surgery. Some general surgeons obtain advanced training in this field (most commonly surgical critical care) and specialty certification surgical critical care. General surgeons must be able to deal initially with almost any surgical emergency. Often, they are the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Large Intestine
The large intestine, also known as the large bowel, is the last part of the gastrointestinal tract and of the digestive system in tetrapods. Water is absorbed here and the remaining waste material is stored in the rectum as feces before being removed by defecation. The colon is the longest portion of the large intestine, and the terms are often used interchangeably but most sources define the large intestine as the combination of the cecum, colon, rectum, and anal canal. Some other sources exclude the anal canal. In humans, the large intestine begins in the right iliac region of the pelvis, just at or below the waist, where it is joined to the end of the small intestine at the cecum, via the ileocecal valve. It then continues as the colon ascending the abdomen, across the width of the abdominal cavity as the transverse colon, and then descending to the rectum and its endpoint at the anal canal. Overall, in humans, the large intestine is about long, which is about on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newcastle University
Newcastle University (legally the University of Newcastle upon Tyne) is a UK public research university based in Newcastle upon Tyne, North East England. It has overseas campuses in Singapore and Malaysia. The university is a red brick university and a member of the Russell Group, an association of research-intensive UK universities. The university finds its roots in the School of Medicine and Surgery (later the College of Medicine), established in 1834, and the College of Physical Science (later renamed Armstrong College), founded in 1871. These two colleges came to form the larger division of the federal University of Durham, with the Durham Colleges forming the other. The Newcastle colleges merged to form King's College in 1937. In 1963, following an Act of Parliament, King's College became the University of Newcastle upon Tyne. The university subdivides into three faculties: the Faculty of Humanities and Social Sciences; the Faculty of Medical Sciences; and the Facult ...

Volvulus
A volvulus is when a loop of intestine twists around itself and the mesentery that supports it, resulting in a bowel obstruction. Symptoms include abdominal pain, abdominal bloating, vomiting, constipation, and bloody stool. Onset of symptoms may be rapid or more gradual. The mesentery may become so tightly twisted that blood flow to part of the intestine is cut off, resulting in ischemic bowel. In this situation there may be fever or significant pain when the abdomen is touched. Risk factors include a birth defect known as intestinal malrotation, an enlarged colon, Hirschsprung disease, pregnancy, and abdominal adhesions. Long term constipation and a high fiber diet may also increase the risk. The most commonly affected part of the intestines in adults is the sigmoid colon with the cecum being second most affected. In children the small intestine is more often involved. The stomach can also be affected. Diagnosis is typically with medical imaging such as plain X-rays, a ...

Chilaiditi Syndrome
Chilaiditi syndrome is a rare condition when pain occurs due to transposition of a loop of large intestine (usually transverse colon) in between the diaphragm and the liver, visible on plain abdominal X-ray or chest X-ray. Normally this causes no symptoms, and this is called Chilaiditi's sign. The sign can be permanently present, or sporadically. This anatomical variant is sometimes mistaken for the more serious condition of having air under the diaphragm (pneumoperitoneum) which is usually an indication of bowel perforation, possibly leading to surgical interventions. Chilaiditi syndrome refers only to complications in the presence of Chilaiditi's sign. These include abdominal pain, torsion of the bowel (transverse colon volvulus) or shortness of breath. Causes The exact cause is not always known, but it may occur in patients with a long and mobile colon ( dolichocolon), chronic lung disease such as emphysema, or liver problems such as cirrhosis and ascites. Chilaiditi's sign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elderly
Old age refers to ages nearing or surpassing the life expectancy of human beings, and is thus the end of the human life cycle. Terms and euphemisms for people at this age include old people, the elderly (worldwide usage), OAPs (British usage which stands for Old Age Pensioner), seniors, senior citizens (American usage), older adults (in the social sciences), and the elders (in many cultures). Elderly people often have limited regenerative abilities and are more susceptible to AIDS, herpes, hemorrhoids, and other illnesses than younger adults. A number of other disciplines and domains concern the aging and the aged, such as organic processes of aging (senescence), medical studies of the aging process ( gerontology), diseases that afflict older adults ( geriatrics), technology to support the aging society (gerontechnology), or leisure and sport activities adapted to older people, such as senior sport. The elderly face various social issues concerning retirement, loneliness, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abdominal X-ray
An abdominal x-ray is an x-ray of the abdomen. It is sometimes abbreviated to AXR, or KUB (for kidneys, ureters, and urinary bladder). Indications In children, abdominal x-ray is indicated in the acute setting: *Suspected bowel obstruction or gastrointestinal perforation; Abdominal x-ray will demonstrate most cases of bowel obstruction, by showing dilated bowel loops. * Foreign body in the alimentary tract; can be identified if it is radiodense. *Suspected abdominal mass *In suspected intussusception, an abdominal x-ray does not exclude intussusception but is useful in the differential diagnosis to exclude perforation or obstruction. Yet, CT scan is the best alternative for diagnosing intra-abdominal injury. Computed tomography provides an overall better surgical strategy planning, and possibly less unnecessary laparotomies. Abdominal x-ray is therefore not recommended for adults with acute abdominal pain presenting in the emergency department. Projections The standar ...

Colonoscopy
Colonoscopy () or coloscopy () is the endoscopic examination of the large bowel and the distal part of the small bowel with a CCD camera or a fiber optic camera on a flexible tube passed through the anus. It can provide a visual diagnosis (''e.g.,'' ulceration, polyps) and grants the opportunity for biopsy or removal of suspected colorectal cancer lesions. Colonoscopy can remove polyps smaller than one millimeter. Once polyps are removed, they can be studied with the aid of a microscope to determine if they are precancerous or not. Colonoscopy is similar to sigmoidoscopy—the difference being related to which parts of the colon each can examine. A colonoscopy allows an examination of the entire colon (1,200–1,500mm in length). A sigmoidoscopy allows an examination of the distal portion (about 600mm) of the colon, which may be sufficient because benefits to cancer survival of colonoscopy have been limited to the detection of lesions in the distal portion of the colon ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolichos (race)
The dolichos or dolichus (Greek: , English translation: "long race") in the ancient Olympic Games was a long race ( 4800 m) introduced in 720 BC. Separate accounts of the race present conflicting evidence as to the actual length of the dolichos. However, the average stated length of the race was approximately 12.5 laps, or about three miles. The event was run similarly to modern marathons (the runners would begin and end their event in the stadium proper), but the race course would wind its way through the Olympic grounds. The course would often flank important shrines and statues in the sanctuary, passing by the Nike statue by the temple of Zeus before returning to the stadium.Miller, p. 32. "At the next Olympiad, in 720, a long-distance footrace called the ''dolichos'' was added to the program. The sources are not unanimous about the length of this race: some claim that it was twenty laps of the stadium track, others that it was twenty-four. It may have differed from sit ...
