Developmental abnormalities, blood pressure variability and renal disease in Riley Day syndrome

The Riley-Day syndrome

Familial dysautonomia (Riley et al., 1949) is an autosomal recessive disease affecting Jews of Eastern European ancestry (Brunt and McKusick, 1970). As the name implies the autonomic nervous system is defective, and this is seen clinically as defective control of temperature, blood pressure, and swallowing, by skin blotching, excessive sweating, lack of tearing, and bowel disturbance. Abnormali...

Familial dysautonomia (Riley-Day syndrome).

Familial dysautonomia, also known as Riley-Day syndrome, is a disorder of autonomic nervous system with an autosomal recessive mode of inheritance. Reduction and/or loss of unmyelinated and small myelinated fibers is found, as reduction of dopamine beta-hydroxylase in blood. The diagnosis is based on clinical features: diminished lacrimation, insensitivity to pain, poor temperature control, abo...

Day-to-day blood pressure variability and dementia

Riley-Day Syndrome (congenital familial dysautonomia).

THIS rare disease is of particular importance to ophthalmologists because of the congenital failure of tear production and corneal anaesthesia. It was first described as an entity by Riley, Day, Greeley, and Langford (1949). Since then, many further cases have been reported (Braun-Vallon and Bessman, 1960; Levin, 1960; Laxdal, Khera, and Haworth, 1961; Thieffry, Joseph, Martin, Job, and Lorthol...
