| retrograde intussusception | The invagination of a lower segment of the bowel into one just above. (05 Mar 2000) |
|---|---|
| colic intussusception | The ensheathing of one portion of the colon into another. (05 Mar 2000) |
| double intussusception | <gastroenterology, surgery> A second intussusception that involves the bowel above the first; the first intussusception is followed by contraction of the bowel wall around it, and the solid mass so formed is enveloped by the proximal portion of the bowel and is thus the cause of the second intussusception. (05 Mar 2000) |
| ileal intussusception | Intussusception in which one portion of the ileum is ensheathed in another portion of the same division of the bowel. (05 Mar 2000) |
| ileocaecal intussusception | Intussusception in which the lower segment of the ileum passes through the valve of the colon into the caecum. (05 Mar 2000) |
| ileocolic intussusception | Intussusception in which the lower portion of the ileum with the valve of the caecum passes into the ascending colon. (05 Mar 2000) |
| intussusception | Intussusception refers to a telescoping of one portion of the intestine into another. This results in reduced blood supply to the affected portion of the intestine. Intussusception is seen almost exclusively in children between the ages of 5 months and 1 year. It is three times more common in boys and the exact cause is unknown. In older children, tumours and polyps can cause intussusception. (27 Sep 1997) |
| jejunogastric intussusception | A rare complication following gastrojejunostomy in which the afferent or the efferent loop of bowel invaginates into the stomach. (05 Mar 2000) |
| adrenal hyperplasia, congenital | A group of inherited disorders of adrenal steroidogenesis, the physical expression of which varies with the sex of the patient, the severity of the congenital enzyme defect, and the age at which the defect makes its presence felt. The most common form, the simple virilizing form, is due to a 21-hydroxylase deficiency. There is also a salt-losing form (a more complete 21-hydroxylase deficiency), a hypertensive form (11-hydroxylase deficiency), a 17-hydroxylase deficiency form, a desmolase deficiency form, and a 3-beta-hydroxysteroid deficiency form.

| anaemia, dyserythropoietic, congenital | A familial disorder characterised by anaemia with multinuclear erythroblasts, karyorrhexis, asynchrony of nuclear and cytoplasmic maturation, and various nuclear abnormalities of bone marrow erythrocyte precursors. Type II is the most common of the 3 types of congenital dyserythropoietic anaemia; it is often referred to as hempas, based on the hereditary erythroblast multinuclearity with positive acidified serum test. (12 Dec 1998) |
| anaemia, haemolytic, congenital | Haemolytic anaemia due to various intrinsic defects of the erythrocyte. (12 Dec 1998) |
| anaemia, haemolytic, congenital nonspherocytic | Any one of a group of congenital haemolytic anaemias in which there is no abnormal haemoglobin or spherocytosis and in which there is a defect of glycolysis in the erythrocyte. In some cases, pyruvate kinase deficiency has been demonstrated; in other cases, glucose-6-phosphate dehydrogenase deficiency has been demonstrated. (12 Dec 1998) |
| bovine congenital ataxia | An autosomal recessive ataxia seen in several European breeds of cattle. (05 Mar 2000) |
| bullous congenital ichthyosiform erythroderma | Diffusely red, eroded skin at birth, with subsequent scaling, tending to improve in later life, characterised by generalised epidermolytic hyperkeratosis and autosomal dominant inheritance. See: epidermolytic hyperkeratosis. Synonym: generalised epidermolytic hyperkeratosis, ichthyismus hystrix, ichthyosis hystrix. (05 Mar 2000) |
| pain insensitivity, congenital | Absence of sensibility to pain or inability to feel pain. The condition is present at birth. (12 Dec 1998) |
