dys- +

Referring to the wasting of the gray matter of the nervous system.

1. Wasting of the gray matter of the nervous system.
2. Any degenerative disease of gray matter in the central nervous system.

A condition characterized by the presence of many congenital anomalies of the connective tissues.

An occurrence of symptoms indistinguishable from those of bacillary dysentery, resulting frokm causes other than the presence of the specific microorganisms of bacillary dysentery.

Inducing a dreamlike or delusional mental state; hallucinatory.

1. An inheritable disorder of bone, characterized by a short stature, a large skull with absence of knitting of the anterior frontanel, receding chin, shortness of fingers, and toes, and fragility of bones.

Radiographs show an abnormal thickness of bones, which is responsible for the fractures.

2. An autosomal recessive disease that affects bones and resembles osteopetrosis, but the disease is considered to be mild and not associated with hematological or neurological abnormalities.

The only treatment is surgical correction of deformities and fractures.

Bad breath, some causes include smoking, poor dental hygiene, alcoholism, throat infection, dental infection, sinusitis, lung infection, gum disease, impacted tooth or teeth, and a foreign body in the nose (children).

An abnormal heart rhythm with a rate greater than 100 beats per minute in an adult; the term tachyarrhythmia is usually used instead.

1. Impaired nutrition of hair, which can lead to baldness.
2. Defective nutrition of hair, often culminating in alopecia. May be acquired or congenital; the latter often with metabolic or other birth defects.

Congenital defect of copper metabolism manifested in short, sparse, poorly pigmented kinky hair.

This condition is associated with failure to thrive in life, physical and mental retardation, and progressive severe deterioration of the brain; apparently a defect of copper transport.

1. An abnormality of the hair shaft in which the fine, brittle hairs show alternating light and dark zones when viewed under a polarizing microscope.

The sulfur content of the hair is greatly reduced and mental retardation has frequently been a related feature.

2. Congenital fragile hair with multiple fractures resulting from low sulfur-containing amino acid, cysteine, content of the hair, mental impairment, and short stature.

1. A congenital condition of females associated with a defect or absence of an X-chromosome, characterized by short stature, sexual underdevelopment, and other physical abnormalities.
2. A genetic disorder affecting women in which only one X-chromosome per cell is present, instead of two, resulting in underdeveloped ovaries and underdevelopment of the womb, vagina, and breasts.

Named after Henry Hubert Turner (1892–1970), an American endocrinologist; this congenital endocrine disorder, or ovarian dysgenesis, is caused by the failure of the ovaries to respond to pituitary hormone stimulation.

Clinically, a female with this endocrine disorder has a shorter than normal stature; absence of secondary sexual characteristics, with infantile development of the vagina, uterus, and breast; failure to develop sexual maturation, webbing of the neck, and inconsistent cardiac defects.
