| retrograde menstruation | A flow of menstrual blood back through the fallopian tubes; it sometimes carries with it endometrial cells. Supplementary menstruation, bleeding from the navel or urinary tract due to endometriosis occurring at the time of menstruation. Suppressed menstruation, nonappearance of menstrual bleeding from whatever cause. Vicarious menstruation, bleeding from any surface other than the mucous membrane of the uterine cavity, occurring periodically at the time when the normal menstruation should take place.

| retrograde metamorphosis | An effect whereby the productivity of a microbial strain used in a commercial process diminishes after repeated transfer from one culture media to another, often caused by genetic mutation. (14 Nov 1997) |
| retrograde P wave | The P wave pattern in the electrocardiogram representing retrograde depolarisation of the atria, the impulse spreading from the A-V junction or the lower atrium upward. (05 Mar 2000) |
| retrograde pyelography | Pyelography in which contrast material is injected into the ureters from an endoscope in the bladder. (05 Mar 2000) |
| cholangiopancreatography, endoscopic retrograde | Fibreoptic endoscopy designed for duodenal observation and cannulation of vater's ampulla, in order to visualise the pancreatic and biliary duct system by retrograde injection of contrast media. Endoscopic (vater) papillotomy (sphincterotomy, endoscopic) may be performed during this procedure. (12 Dec 1998) |
| endoscopic retrograde cholangiopancreatogram | A diagnostic procedure to examine diseases of the liver, bile ducts and pancreas. It is uncomfortable but not painful, is performed under intravenous sedation, usually without general anaesthesia, and has a low incidence of complications. ERCP provides important information unobtainable by other diagnostic means. Therapeutic measures can often be take at the time of ERCP to remove stones in the bile ducts or to relieve obstructions of the bile ducts. (12 Dec 1998) |
| endoscopic retrograde cholangiopancreatography | <investigation, procedure> A diagnostic-therapeutic procedure that involves the X-ray of the pancreatic duct and biliary tree after the selective introduction of a contrast material into the common bile duct and pancreatic duct. In this procedure, a flexible endoscope is passed through the mouth and down into the duodenum. A catheter is then passed through the endoscope and inserted into the pancreatic and bile ducts. It is uncomfortable but not painful, is performed under intravenous sedation, usually without general anaesthesia, and has a low incidence of complications. A contrast agent is injected into the catheter which highlights the coarse and calibre of the ducts. Narrowing, stones or ductal tumours can be identified with this procedure. Therapeutic measures can often be take at the time of ERCP to remove stones in the bile ducts or to relieve obstructions of the bile ducts, so that traditional open surgeries can be avoided. ERCP is increasingly accepted as the diagnostic and therapeutic procedure of choice in identifying and removing gallstones in the bile ducts. Acronym: ERCP (12 Dec 1998) |
| adipose degeneration | Abnormal formation of microscopically visible droplets of fat in the cytoplasm of cells, as a result of injury. Synonym: adipose degeneration, steatosis. (05 Mar 2000) |
| adiposogenital degeneration | A disorder characterised primarily by obesity and hypogonadotrophic hypogonadism in adolescent boys; dwarfism is rare, and when present is thought to reflect hypothyroidism. Visual loss, behavioural abnormalities, and diabetes insipidus may occur. Frohlich's syndrome often is used synonymously for this disorder, although the original case involved a pituitary tumour; most cases are thought to result from hypothalamic dysfunction in areas regulating appetite and gonadal development. The most common causes are pituitary and hypothalamic neoplasms. Synonym: adiposis orchica, adiposogenital degeneration, adiposogenital dystrophy, adiposogenital syndrome, hypophysial syndrome, hypothalamic obesity with hypogonadism. Origin: L. Fr. G. Dys-, bad, + trophe, nourishment (05 Mar 2000) |
| age-related macular degeneration | A common macular degeneration beginning with drusen of the macula and pigment disruption and sometimes leading to severe loss of central vision. (05 Mar 2000) |
| albuminous degeneration | An obsolete terms for cloudy swelling. (05 Mar 2000) |
| amyloid degeneration | Infiltration of amyloid between cells and fibres of tissues and organs. Synonym: waxy degeneration. (05 Mar 2000) |
| angiolithic degeneration | Calcareous degeneration of the walls of the blood vessels. (05 Mar 2000) |
| ascending degeneration | Retrograde degeneration of an injured nerve fibre; i.e., toward the nerve cell of the fibre, degeneration cephalad to a spinal cord lesion. (05 Mar 2000) |
| atheromatous degeneration | Focal accumulation of lipid material (atheroma) in the intima and subintimal portion of arteries, eventually resulting in fibrous thickening or calcification. (05 Mar 2000) |
