dysplasia

 [dis-pla´zhah]
an abnormality of development; in pathology, alteration in size, shape, and organization of adult cells. See also dysgenesis. adj., adj dysplas´tic.
bronchopulmonary dysplasia chronic lung disease of premature infants with hyaline membrane disease who have needed high concentrations of oxygen and assisted ventilation. Factors related to its development include alveolar damage due to hyaline membrane disease, oxygen toxicity, positive pressure ventilation, and endotracheal intubation. Treatment includes supportive measures and oxygen therapy. Recovery and normal pulmonary function usually occur by the age of 6 months to 1 year; however, some infants may exhibit limited tolerance to exercise.
craniometaphyseal dysplasia metaphyseal dysplasia associated with overgrowth of the head bones, leonine facies, and increased distance between the eyes.
Craniometaphyseal dysplasia. From Dorland's, 2000.
cretinoid dysplasia a developmental abnormality characteristic of cretinism, consisting of retarded ossification and smallness of the internal and reproductive organs.
cystic renal dysplasia renal dysplasia in which there are cysts.
developmental dysplasia of the hip (DDH) instability of the hip joint leading to dislocation in the neonatal period. Although it may be associated with various neuromuscular disorders, such as myelodysplasia, or occur in utero, it most commonly occurs in neurologically normal infants and is multifactorial in origin. Usually there is laxity of the hip ligaments. Most affected infants are first-born children and 30 to 50 per cent present in the breech position. About 90 per cent of those affected are girls. The condition was formerly called congenital dislocation of the hip, but because the dislocation is not normally present at birth but develops later, the term developmental dysplasia of the hip is preferred.
ectodermal dysplasia any of a group of hereditary disorders involving absence or deficiency of tissues and structures derived from the embryonic ectoderm, such as teeth, hair, nails, and certain glands.
fibromuscular dysplasia dysplasia with fibrosis of the muscular layer of an artery wall, with collagen deposition and hyperplasia of smooth muscle, causing stenosis and hypertension. It most commonly occurs in the renal arteries and is a major cause of renovascular hypertension.
fibrous dysplasia of bone thinning of the cortex of bone and replacement of bone marrow by gritty fibrous tissue containing bony spicules, causing pain, disability, and gradually increasing deformity; it may affect a single bone (monostotic fibrous dysplasia) or several or many bones (polyostotic fibrous dysplasia). When associated with melanotic pigmentation of the skin and endocrine disorders, it is known as albright's syndrome.
metaphyseal dysplasia a disturbance in enchondral bone growth, failure of modeling causing the ends of the shafts to remain larger than normal in circumference.
oculodentodigital dysplasia a rare hereditary condition, characterized by bilateral microphthalmos, abnormally small nose with anteverted nostrils, hypotrichosis, dental anomalies, camptodactyly, syndactyly, and missing phalanges of the toes.
renal dysplasia a congenital disorder of the kidney, with persistence of cartilage, undifferentiated mensenchyme, and immature collecting tubules, as well as with abnormal lobar organization and nearly always cysts; it may be unilateral or bilateral and total or subtotal. Total bilateral dysplasia is rapidly fatal in the neonatal period, while milder disease may be asymptomatic.
retinal dysplasia a general term for a congenital defect resulting from the abnormal growth and differentiation of a retina that fails to develop into functioning tissue.

developmental dysplasia of the hip (DDH)

instability of the hip joint leading to dislocation in the neonatal period. Although it may be associated with various neuromuscular disorders, such as myelodysplasia, or occur in utero, it most commonly occurs in neurologically normal infants and is multifactorial in origin. Usually there is laxity of the hip ligaments. Most affected infants are firstborn children, and 30% to 50% present in the breech position. About 90% of those affected are girls. The condition was formerly called congenital dislocation of the hip, but because the dislocation is not normally present at birth but develops later, the term developmental dysplasia of the hip is preferred.

dysplasia

(dis-pla'zh(e-)a) [ dys- + -plasia]
Abnormal development of tissue. Synonym: alloplasia; heteroplasia

anal dysplasia

Anal intraepithelial neoplasia.

anhidrotic dysplasia

A congenital condition marked by absent or deficient sweat glands, intolerance of heat, and abnormal development of teeth and nails.

arrhythmogenic right ventricular dysplasia

Abbreviation: ARVD
A rare degenerative disease of desmosomes within heart muscle that may produce life-threatening cardiac arrhythmias. It is a cause of sudden death or ventricular tachycardia in athletes. The dysplasia is diagnosed by a combination of tests (specific angiographic, electrocardiographic, echocardiographic, MRI, and biopsy or necropsy criteria). Some forms of the disease are autosomal dominantly inherited. Synonym: arrhythmogenic right ventricular cardiomyopathy; arrhythmogenic right ventricular dysplasia/cardiomyopathy

bronchopulmonary dysplasia

The need for supplemental oxygen in an infant born prematurely, esp. when that need is present after 36 weeks' gestation. Synonym: chronic lung disease of the newborn

Patient care

A team approach is necessary to provide optimal inpatient and outpatient care to infants and their families. Educating the family about the disease, its treatment, and its prognosis are critical to providing optimal care to affected infants. Inpatient care emphasizes respiratory support for the infant, appropriate nutrition to support growth and development, and regular physical contact with parents to encourage bonding esp. during long, and emotionally taxing hospital stays. Enrolling the family in a follow-up program with supportive care for the infant is important to help the parents in the early months after hospital discharge. Educating the family about continuing care about follow-up appointments and therapies is essential. The care team addresses the nutritional, developmental, general medical and social services each infant and family need to promote optimal long-term development of the infant.

cervical dysplasia

Precancerous changes in the cells of the uterine cervix, typically obtained for cytological examination by brushing or scraping cells from the cervix during a Pap test or colposcopy. Changes found on the Papanicolaou test (Pap test) are called a squamous intraepithelial lesion (SIL) and are classified as low grade (LSIL), high grade (HSIL), or possibly malignant. When a biopsy of the cervix is performed, the dysplasia is called a cervical intraepithelial neoplasia (CIN) and is classified as CIN I-mild, CIN II-moderate, and CIN III-severe to carcinoma in situ.

chondroectodermal dysplasia

Ellis–van Creveld syndrome .

developmental dysplasia of the hip

Congenital dislocation of the hip.

ectodermal dysplasia

Any of a group of rare inherited disorders in which there are defects in the function or development of glands, hair, nails, or teeth, i.e., organs that originate embryologically in the ectoderm.

fibromuscular dysplasia

A dysplasia of the fibrous and muscular walls of an artery, resulting in impaired blood flow or stenosis. It is most often found in the renal arteries, esp. in young women as a cause of hypertension, or in the carotid arteries of adults.

fibrous dysplasia

A rare, nonheritable congenital bone disease characterized by disorganized alignment of collagen within bone and weak bone formation. Symptoms include bone pain, bone deformities, fractures, and neurological deficits. Some patients are also affected by endocrine disorders, such as diabetes mellitus, acromegaly, or hyperprolactinemia. There are two forms of the disease: monostotic fibrous dysplasia is a variant of the disease in which a single bony lesion is found; in polyostotic fibrous dysplasia, lesions are found in multiple bones, including long bones, facial and cranial bones, or other locations.

hereditary ectodermal dysplasia

A form of anhidrotic dysplasia marked by few or absent sweat glands and hair follicles, smooth shiny skin, abnormal or absent teeth, nail deformities, cataracts or corneal alterations, absence of mammary glands, a concave face, prominent eyebrows, conjunctivitis, deficient hair growth, and mental retardation.
