Nasal Polyp: From 1 Different Sources
A growth in the lining of the nose, usually attached by a small stalk.
Most nasal polyps are noncancerous, but they may need to be removed if they cause nasal obstruction.

The presence of a crop, or large number, of polypi (see POLYPUS). The most important form of polyposis is that known as familial polyposis coli. This is a hereditary disease characterised by the presence of large numbers of polypoid tumours in the large bowel. Every child born to an affected parent stands a ?fty-?fty chance of developing the disease. Its importance is that sooner or later one or more of these tumours undergoes cancerous change. If the affected gut is removed surgically before this occurs, and preferably before the age of 20, the results are excellent.... polyposis
A suggestion by two epidemiologists, made in the British Medical Journal in 2003, that many lives could be saved if all persons aged over 55 took a daily combination pill they termed the polypill. Its components would be ASPIRIN, a CHOLESTEROL-lowering agent, FOLIC ACID and two blood-pressure-lowering agents. The suggestion caused a massive correspondence as it implied treating a whole population rather than individuals considered to be at special risk.... polypill

either of a pair of narrow oblong bones that together form the bridge and root of the nose. See skull.... nasal bone
a fixation device to prevent patients pulling out *nasogastric (NG) tubes. Two tiny catheter-mounted magnets are inserted either side of the nasal septum to meet in the nasopharyngeal space. This leaves tapes exiting from each nostril. A clip then secures the tapes and NG tube together.... nasal bridle
the space inside the nose that lies between the floor of the cranium and the roof of the mouth. It is divided into two halves by a septum: each half communicates with the outside via the nostrils and with the nasopharynx through the posterior nares.... nasal cavity
(turbinate bone) any of three thin scroll-like bones that form the sides of the *nasal cavity. The superior and middle nasal conchae are part of the *ethmoid bone; the inferior nasal conchae are a separate pair of bones of the face. See skull.... nasal concha
(in Britain), a vaccine currently offered to all 2- and 3-year-olds in the form of a spray into each nostril. It contains live forms of the influenza virus that have been attenuated (weakened). The vaccine stimulates the immune system but does not cause disease in healthy people.... nasal flu vaccine
a hormone released from the D cells of the *islets of Langerhans of the pancreas in response to protein in the small intestine. Its actions are to inhibit pancreatic bicarbonate and protein enzyme secretion and to relax the gall bladder. It belongs to a family of similar hormones that have actions on appetite and food metabolism.... pancreatic polypeptide
n. the endoscopic or surgical removal of a *polyp. The technique used depends upon the site and size of the polyp. Endoscopically, polyps can be removed by various methods. A hot biopsy involves coagulation of a small polyp using a diathermy current passed through biopsy forceps, which obtains a sample for analysis at the same time. Cold biopsy involves removal of a polyp using forceps alone, thereby decreasing the perforation risk. Snare polypectomy uses a wire loop (snare) to cut through the base of the polyp. This is performed with or without a diathermy current (hot snare vs. cold snare); the current reduces the risk of bleeding by coagulating local blood vessels as the snare cuts through the polyp. Endoscopic mucosal resection (EMR) involves lifting a flat polyp by injecting a hypertonic solution into the submucosa beneath the polyp followed by snare polypectomy with diathermy. Nasal polyps may be removed using *endoscopic sinus surgery techniques, sometimes utilizing a *microdebrider.... polypectomy
