Louis-Bar's syndrome
Also known as:
Boder-Sedgwick syndrome
Associated persons:
Elena Boder
Denise Louis-Bar
Robert P. Sedgwick
Description:
A degenerative brain disease characterised by progressive cerebellar ataxia, athetoid movements, nystagmus, slow dysarthric speech, telangiectasis of the bulbar conjunctiva, recurrent respiratory infections, mental retardation (50%) and an increased incidence of lymphoreticular malignancies. It affects both sexes equally, with onset at the age of about four years. Death usually occurs in adolescence or early adulthood of a pulmonary infection or a lymphoreticular malignant tumour. It is transmitted as an autosomal recessive trait.
The first description of patients with ataxia-telangiectasia was published in French in 1926 by the internist Ladislav Syllaba (1868-1930) and the neurologist Kamil Henner (1895-1967). They reported 3 adolescent Czech siblings with progressive choreoathetosis and ocular telangiectasia. Denise Louis-Bar in 1941 reported a 9-year-old girl with progressive cerebellar ataxia, mental retardation and bilateral oculocutaneous telangiectasia.
In 1958, Elena Boder and Robert P. Sedgwick studied 8 cases from 5 unrelated families, including 6 familial cases. They emphasized the heredofamilial nature of the disease and the susceptibility of these patients to sinopulmonary infections. Boder and Sedgwick introduced the term ataxia-telangiectasia.
