Mechanically induced Roemheld syndrome is characterized by pressure in the epigastric and left hypochondriac region. Often the pressure is in the fundus of the stomach, the esophagus or distention of the bowel. It is believed this leads to elevation of the diaphragm, and secondary displacement of the heart. This reduces the ability of the heart ...
Hypertropia is a condition of misalignment of the eyes ( strabismus ), whereby the visual axis of one eye is higher than the fellow fixating eye. Hypotropia is the similar condition, focus being on the eye with the visual axis lower than the fellow fixating eye. Dissociated vertical deviation is a special type of hypertropia leading to slow ...

Ataxia–telangiectasia. Ataxia–telangiectasia ( AT or A–T ), also referred to as ataxia–telangiectasia syndrome or Louis–Bar syndrome, [ 1] is a rare, neurodegenerative disease causing severe disability. Ataxia refers to poor coordination and telangiectasia to small dilated blood vessels, both of which are hallmarks of the disease. [ 2]
