| reflux otitis media | Otitis media caused by passage of nasopharyngeal secretions through the eustachian tube. (05 Mar 2000) |
|---|---|
| hepatojugular reflux | An elevation of venous pressure visible in the jugular veins and measurable in the veins of the arm, produced in active or impending congestive heart failure by firm pressure with the flat hand over the abdomen. Often called hepatojugular reflex when pressure is exclusively over the liver. Synonym: abdominojugular reflux. (05 Mar 2000) |
| pyelotubular reflux | Urinary reflux from renal pelvis and calices into the collecting ducts. This is seen as a blush of the renal pyramid on voiding cystourethrography. Synonym: pyelotubular reflux. (05 Mar 2000) |
| duodenogastric reflux | Reflux of duodenal contents into the stomach. (12 Dec 1998) |
| intrarenal reflux | Urinary reflux from renal pelvis and calices into the collecting ducts. This is seen as a blush of the renal pyramid on voiding cystourethrography. Synonym: pyelotubular reflux. (05 Mar 2000) |
| oesophageal reflux | A condition wherein stomach contents regurgitate or back up (reflux) into the oesophagus (a long cylindrical tube that transports food from the mouth to the stomach). The food in the stomach is partially digested by stomach acid and enzymes. Normally, the partially digested acid content in the stomach is delivered by the stomach muscle into the small intestine for further digestion. In oesophageal reflux, stomach acid content refluxes backwards up into the oesophagus, occasionally reaching the breathing passages, causing inflammation and damage to the oesophagus, as well as to the lung and larynx (the voice box). The process is medically termed gastroesophageal reflux disease (GERD). 10% of patients with GERD develop a Barrett's oesophagus which can increase the risk of cancer of the oesophagus. (12 Dec 1998) |
| ureterorenal reflux | Backward flow of urine from ureter into renal pelvis. (05 Mar 2000) |
| cancer, gastric | Cancer of the stomach, the major organ that holds food for digestion. Stomach cancer (gastric cancer) can develop in any part of the stomach and spread to other organs. Stomach ulcers do not appear to increase a person's risk of developing stomach cancer. Symptoms of stomach cancer are often vague, such as loss of appetite and weight. The cancer is diagnosed with a biopsy of stomach tissue during a procedure called an endoscopy. (12 Dec 1998) |
| vagotomy, proximal gastric | Vagal denervation of that part of the stomach lined with acid secreting mucosa. Since the procedure leaves the vagal branches to the antrum and pylorus intact, it circumvents gastric drainage required with truncal vagotomy techniques. (12 Dec 1998) |
| gastric | <anatomy> Of or relating to the stomach. (09 Oct 1997) |
| gastric acid | Hydrochloric acid present in gastric juice. (12 Dec 1998) |
| gastric acidity determination | Gastric analysis for determination of free acid or total acid. (12 Dec 1998) |
| gastric algid malaria | See: algid malaria. Induced malaria, malaria acquired by artificial means, e.g., via blood transfusion, common syringes, or malariotherapy. Intermittent malaria, a malarial fever, usually of the tertian or quartan type, in which there is complete apyrexia, with absence of the other symptoms, in the intervals between the paroxysms. (05 Mar 2000) |
| gastric analysis | Measurement of pH and acid output of stomach contents; basal acid output can be determined by collecting the overnight gastric secretion or by a 1-hr collection; maximal acid output is determined following injection of histamine; output is measured by titration with a strong base. (05 Mar 2000) |
| gastric area | One of a number of small polygonal area's, 1-6 mm in diameter, separated by linear depressions on the surface of the mucous membrane of the stomach; they contain the gastric pits, with several gastric glands opening into each pit. Synonym: area gastrica. (05 Mar 2000) |
