| neural tube | <embryology> The progenitor of the central nervous system. See: neural plate, neurulation. (18 Nov 1997) |
|---|---|
| neural tube defect | <neurology, paediatrics> Abnormal development during embryonic life of the neural tube producing congenital malformations of the nervous system due to closure failure of the neural tube. The structure gives rise to the central nervous system (the brain and spinal cord), and failure to close results in anencephaly (absence of the cranial vault and absence of most or all of the cerebral hemispheres of the brain) and spina bifida or meningomyelocele (open spina with exposure and protusion of the spinal cord). The risk of neuroal tube defects can be decreased by the mother taking folic acid during pregnancy. (04 Jul 1999) |
| dorsal plate of neural tube | The thin layer of the embryonic neural tube connecting the alar plate's dorsally. Synonym: dorsal plate of neural tube. (05 Mar 2000) |
| dorsolateral plate of neural tube | The dorsal division of the lateral walls of the neural tube in the embryo; it gives rise to neurons relaying afferent impulses to higher centres; in the adult such neurons compose the sensory nuclei of the spinal cord and brainstem. Synonym: lamina alaris, alar plate of neural tube, dorsolateral plate of neural tube, lamina dorsalis, wing plate. (05 Mar 2000) |
| anhidrotic ectodermal dysplasia | A hereditary condition (most often x linked) that is characterised by the abnormal development of skin, absence of sweat glands, dry eyes and abnormal development of teeth. Symptoms include absent teeth, peg teeth, inability to sweat, thin skin and heat intolerance. Mucous membrane involvement may result in a foul-smelling nasal discharge. The inability to sweat leads to the inability to maintain normal body temperature in a warm environment. Some may exhibit fevers and will require artificial cooling. Inheritance: mostly sex-linked (X chromosome). Origin: Gr. Plassein = to form (12 Nov 1997) |
| anterofacial dysplasia | Abnormal growth of the face or cranium in an anteroposterior direction as seen and measured with a cephalogram. (05 Mar 2000) |
| arrhythmogenic right ventricular dysplasia | A congenital cardiomyopathy in which transmural infiltration of adipose tissue results in weakness and aneurysmal bulging of the infundibulum, apex, and posterior basilar region of the right ventricle and leads to ventricular tachycardia arising in the right ventricle. (12 Dec 1998) |
| asphyxiating thoracic dysplasia | Hereditary hypoplasia of the thorax, associated with pelvic skeletal abnormality. Synonym: asphyxiating thoracic chondrodystrophy, Jeune's syndrome, thoracic-pelvic-phalangeal dystrophy. (05 Mar 2000) |
| bronchopulmonary dysplasia | <embryology, paediatrics> A form of chronic lung disease of uncertain cause sometimes seen in children who have received mechanical respiratory support (with high oxygenation) in the neonatal period. Often associated with those infants who have been treated for hyaline membrane disease. Origin: Gr. Plassein = to form (27 Sep 1997) |
| mammary dysplasia | An obsolete term for fibrocystic condition of the breast. (05 Mar 2000) |
| mandibulofacial dysplasia | A hereditary disorder occurring in two forms: the complete form (franceschetti's syndrome) is characterised by antimongoloid slant of the palpebral fissures, coloboma of the lower lid, micrognathia and hypoplasia of the zygomatic arches, and microtia. It is transmitted as an autosomal trait. The incomplete form (treacher collins syndrome) is characterised by the same anomalies in less pronounced degree. It occurs sporadically, but an autosomal dominant mode of transmission is suspected. (12 Dec 1998) |
| ventriculoradial dysplasia | A congenital syndrome consisting of a ventricular septal defect with associated absence of thumb or radius. (05 Mar 2000) |
| cerebral dysplasia | Abnormal development of the telencephalon. (05 Mar 2000) |
| retinal dysplasia | <ophthalmology> Congenital, often bilateral, retinal abnormality characterised by the arrangement of outer nuclear retinal cells in a palisading or radiating pattern surrounding a central ocular space. This disorder is sometimes hereditary. (12 Dec 1998) |
| cervical dysplasia | A term which describes precancerous changes to the epithelial cells lining the cervix. The diagnosis is made from the microscopic examination of a PAP smear acquired tissue specimen. Less than 5% of all PAP smears will show cervical dysplasia. The peak incidence is in women 25 to 35 years of age. Risk factors include multiple sexual partners, early onset of sexual activity (less than 18), early childbearing (less than 16) and past medical history of a sexually transmitted disease (for example genital warts, genital herpes, HIV infection). Treatment is based on the degree of dysplasia present, as judged by a pathologist. Treatments include cryotherapy and conisation. Origin: Gr. Plassein = to form (27 Sep 1997) |
