gaucher's disease, type 1


A progressive genetic disease caused by a defect in an enzyme. The enzyme, called glucocerebrosidase, is needed to break down the chemical glucocerebroside. The enzyme defect in persons with Gaucher's disease (GD) leads to the accumulation of glucocerebroside in the spleen, liver, and lymph nodes. The most common early sign is enlargement of the spleen (located in the upper left abdomen). Other signs include low red blood cell counts (anaemia), a decrease in blood clotting cells (platelets), increased pigmentation of the skin, and a yellow fatty spot on the white of the eye (a pinguecula). Severe bone involvement can lead to pain and collapse of the bone of the hips, shoulders, and spine. The GD gene is on chromosome 1. The disease is a recessive trait. Both parents carry a GD gene and transmit it for their child with the disease. The parents' risk of a child with the disease is 1 in 4 with each Pregnancy. This type of Gaucher's disease (noncerebral juvenile Gaucher's disease) is most common in Ashkenazi Jews (of European origin) and is the most common genetic disease among Jews in the United States.


tympanic nerve (medicine)


tympanic nerve
<anatomy, nerve> A nerve from the inferior ganglion of the glossopharyngeal nerve, passing through the tympanic canaliculus to the tympanic cavity, forming there the tympanic plexus which supplies the mucous membrane of the tympanic cavity, mastoid cells, and auditory tube; presynaptic parasympathetic fibres also pass through the tympanic nerve via the lesser superficial petrosal nerve to the otic ganglion, where they synapse with postsynaptic fibres that continue to supply the parotid gland.

Synonym: nervus tympanicus, Andersch's nerve, Jacobson's nerve.
