Thanatophoric dysplasia is a severe skeletal disorder characterised by extremely short limbs and folds of extra (redundant) skin on the arms and legs. Other features of this condition include a narrow chest, short ribs, underdeveloped lungs, and an enlarged head with a large forehead and prominent, wide-spaced eyes.
Beskrivning
Thanatophoric dysplasia is a severe skeletal disorder characterised by extremely short limbs and folds of extra (redundant) skin on the arms and legs. Other features of this condition include a narrow chest, short ribs, underdeveloped lungs, and an enlarged head with a large forehead and prominent, wide-spaced eyes.
Researchers have described two major forms of thanatophoric dysplasia, type I and type II. Type I thanatophoric dysplasia is distinguished by the presence of curved thigh bones and flattened bones of the spine (platyspondyly). Type II thanatophoric dysplasia is characterised by straight thigh bones and a moderate to severe skull abnormality called a cloverleaf skull.
The term thanatophoric is Greek for "death bearing." Infants with thanatophoric dysplasia are usually stillborn or die shortly after birth from respiratory failure; however, a few affected individuals have survived into childhood with extensive medical help.

Barretts esofagus
The changed cells of Barrett's oesophagus are not cancerous (malignant). However, these cells have an increased risk, compared with normal gullet (oesophageal) cells, of turning cancerous in time. The changed cells in Barrett's oesophagus can develop something called dysplasia. A cell with dysplasia is an abnormal cell. It is not cancerous but is.

För tidigt födda barn
Premature babies are born too early, before they have fully developed in the womb. They often need extra or intensive medical care and support while their organs continue to develop to a point where they can survive without specialist help. Most premature babies go on to have normal healthy lives, but they are at increased risk of medical and.
