| iodine cysts | An obsolete term used to indicate the cyst's of Iodamoeba butschlii, characterised by a large iodine-positive glycogen vacuole. (05 Mar 2000) |
|---|---|
| odontogenic cysts | Cysts found in the jaws and arising from epithelium involved in tooth formation. They include follicular cysts (e.g., primordial cyst, dentigerous cyst, multilocular cyst), lateral periodontal cysts, and radicular cysts. They may become keratinised (odontogenic keratocysts). Follicular cysts may give rise to ameloblastomas and, in rare cases, undergo malignant transformation. (12 Dec 1998) |
| ovarian cysts | General term for cysts and cystic diseases of the ovary. (12 Dec 1998) |
| enterogenous cysts | Mediastinal cysts derived from cells sequestered from the primitive foregut; may be classified histologically as bronchogenic, oesophageal, or gastric. (05 Mar 2000) |
| jaw cysts | Saccular lesions lined with epithelium and contained within pathologically formed cavities in the jaw; also nonepithelial cysts (pseudocysts) as they apply to the jaw, e.g., traumatic or solitary cyst, static bone cavity, and aneurysmal bone cyst. True jaw cysts are classified as odontogenic or nonodontogenic. (12 Dec 1998) |
| foregut cysts | <radiology> Bronchogenic and enteric cysts: more common on the right, neurenteric cysts: associated with vertebral anomalies, enteric cysts: may contain acid-secreting gastric mucosa;, confirm with TcO4 scan (12 Dec 1998) |
| ABO haemolytic disease of the newborn | Erythroblastosis foetalis due to maternal-foetal incompatibility with respect to an antigen of the ABO blood group; the foetus possesses A or B antigen which is lacking in the mother, and the mother produces immune antibody which causes haemolysis of foetal erythrocytes. (05 Mar 2000) |
| bullous impetigo of newborn | Usually, widely disseminated bullous lesions appearing soon after birth, caused by infection with Staphylococcus aureus. Synonym: impetigo neonatorum, pemphigus gangrenosus. (05 Mar 2000) |
| respiratory distress syndrome of the newborn | A disease seen especially in premature neonates with respiratory distress; characterised postmortem by atelectasis and alveolar ducts lined by an eosinophilic membrane; also associated with reduced amounts of lung surfactant. Synonym: hyaline membrane syndrome, respiratory distress syndrome of the newborn. (05 Mar 2000) |
| pleural effusion in newborn | <radiology> Chylothorax most common cause of large effusion, erythroblastosis foetalis, Turner syndrome, congestive heart failure, infantile polycystic kidneys, wet-lung disease, hypervolaemia (idiopathic or iatrogenic), oesophageal tear, enteric cyst, obstructed pulmonary veins (12 Dec 1998) |
| congenital epulis of newborn | A congenital benign nodular tumour of the alveolar ridge, of unknown histogenesis; histologically, it is composed of large cells with a granular cytoplasm similar to that of a granular cell tumour (myoblastoma). (05 Mar 2000) |
| postnatal pit of the newborn | It marks the site where the embryonic spinal cord attaches to the skin. Synonym: postnatal pit of the newborn. (05 Mar 2000) |
| haemolytic anaemia of newborn | <haematology> A condition which develops in the foetus due to an incompatibility between the mother's blood type (RH factor) and the baby's. Maternal antibodies, which enter the foetal circulation during delivery attack the baby's red blood cells leading to haemolysis (rupture of the cells). Symptoms include an infant with an enlarged liver and spleen, swelling, jaundice and anaemia. (27 Sep 1997) |

| haemolytic disease of the newborn | Abnormal breakup of red blood cells in the foetus or newborn. This is usually due to antibodies made by the mother directed against the baby's red cells. It is typically caused by rh incompatibility, that is differences between the mother and baby uinvolving the rh blood group. (12 Dec 1998) |
