| cystic acne | <dermatology> A form of acne which results from the bacterial infection of cysts deep within the skin. Generally requires treatment with antibiotics and other agents (Isotretinoin). Without treatment cystic acne may result in scarring. (27 Sep 1997) |
| cystic adenomatoid malformation of lung | <radiology> Only true pulmonary cystic disease of newborn, three X-ray types: multicystic, walls of varying thickness, multicystic, one large dominant thin-walled cyst, solid, mediastinal shift common, cysts often contain foetal lung fluid, Treatment: surgery Cf: congenital lobar emphysema (12 Dec 1998) |
| cystic adenomatoid malformation of lung, congenital | A developmental anomaly that usually becomes apparent in the neonatal period with progressive respiratory distress. This malformation is a focal pulmonary dysplasia characterised by a multicystic mass of terminal bronchiolar structures. Ccam is classified into 3 separate types (I, II, III) depending on cyst size. (12 Dec 1998) |
| cystic adnexal masses | <radiology> Ovarian cyst, mature follicle measures up to 2.5 cm at ovulation, corpus luteum cyst common in first 16 weeks of pregnancy, polycystic (Stein-Leventhal) disease, paraovarian cyst, Wolffian duct remnants in broad ligament, ovarian neoplasm, serous cystadenoma (most common benign ovarian tumour), mucinous cystadenoma (usually complex), cystic teratoma (usually complex), endometriosis, diffuse (not detectable by ultrasound), localised (generally anechoic or hypoechoic), ectopic pregnancy, pelvic inflammatory disease, gonorrhoea or chlamydia, localised abscess and hydrosalpinx, non-gynecologic mass, mesenteric cyst, ureterocele, bladder diverticula, lymphocele (12 Dec 1998) |
| cystic artery | <anatomy, artery> Origin, right branch of hepatic; distribution, gall bladder and visceral surface of the liver. Synonym: arteria cystica. (05 Mar 2000) |
| cystic bronchiectasis | Bronchiectasis in which the bronchi end in blind sacs greater in diameter than the draining bronchi. See: saccular bronchiectasis. (05 Mar 2000) |
| cystic carcinoma | <tumour> A carcinoma in which true epithelium-lined cysts are formed, or degenerative changes may result in cystlike spaces. (05 Mar 2000) |
| cystic diathesis | A condition in which multiple cysts form in the liver, kidneys, and other organs. (05 Mar 2000) |
| cystic disease of renal medulla | Presence of small cysts in the renal medulla associated with anaemia, sodium depletion, and chronic renal failure. It is of two types: 1) fatal autosomal recessive or juvenile type (also called familial juvenile nephrophthisis), beginning at about age 10 with an average duration of 6 to 8 years; 2) autosomal dominant or adult type, beginning at about age 30 but with a more fulminant course. Synonym: microcystic disease of renal medulla. (05 Mar 2000) |
| cystic duct | <anatomy> A bile duct that connects the gallbladder to the common bile duct. A gallstone that blocks the cystic duct can lead to inflammation and infection of the gallbladder. See: common bile duct. (27 Sep 1997) |
| cystic duct cholangiography | Radiography of the biliary system after introduction of contrast medium through the cystic duct. (05 Mar 2000) |
| cystic fibrosis | <chest medicine> A generalised disorder of infants, children and young adults, in which there is widespread dysfunction of the exocrine glands, characterised by signs of chronic pulmonary disease (due to excess mucus production in the respiratory tract), pancreatic deficiency, abnormally high levels of electrolytes in the sweat and occasionally by biliary cirrhosis. There is an ineffective immunologic defense against bacteria in the lungs. Pathologically, the pancreas shows obstruction of the pancreatic ducts by amorphous eosinophilic concretions, with consequent deficiency of pancreatic enzymes, resulting in steatorrhoea and azotorrhoea and intestinal malabsorption. The degree of involvement of organs and glandular systems may vary greatly, with consequent variations in the clinical picture. Inheritance: autosomal recessive. (13 Nov 1997) |
| cystic fibrosis antigen | Now known to be MRP 8. See: calgranulins. (18 Nov 1997) |
| cystic fibrosis transmembrane conductance regulator | Gene believed to be defective in cystic fibrosis. Gene encodes a chloride channel, homologous to a family of proteins that actively transport small solutes in an ATP dependent manner (ABC transporters). The regulator protein is a protein which is embedded in the cell membrane and acts as a channel for certain ions to be transported into or out of the cell. The disease cystic fibrosis is caused by a defect in the gene for this protein. (09 Oct 1997) |
