The Epidemiology and Management of Bell's Palsy in the Sudan.

Background: Bell's palsy is an acute idiopathic facial nerve paralysis of sudden onset. It is the most common cause of lower motor neuron facial nerve paralysis with an annual incidence of 15-30 per 100,000.The objective of this work is to study the prevalence and the management of Bell's palsy in the Sudan.

Stereology and ultrastructure of chronic phase axonal and cell soma pathology in stretch-injured central nerve fibers.

Magnetic resonance imaging (MRI) suggests that with survival after human traumatic brain injury (TBI), there is ongoing loss of white and grey matter from the injured brain during the chronic phase. However; direct quantitative experimental evidence in support of this observation is lacking. Using the guinea pig stretch-injury optic nerve model, quantitative evidence by stereology of damage to the optic nerve and retina was sought.
