Peripheral nerves and nerve function in highland Ethiopians.

Introduction: In Ethiopia, where leprosy has been one of the commonest causes of peripheral nerve enlargement and dysfunction, nerve functions are assessed by a battery of "physical" tests. Voluntary Muscle Test (VMT) and Graded Sensory Skin Test (STG) are standard tests used for persons with leprosy. Normal values for nerve function tests (NFT) in Highland Ethiopians have not previously been determined, but have been taken from standard textbooks.

Background: In conjunction with an investigation of nerve function tests of highland Ethiopians in an area of low endemicity of leprosy for 25-30 years, a comprehensive health survey was performed.

Methods: We assessed 236 subjects, 118 females and 118 males, 177 students and 59 adults (Others) aged 10-75 years from Chencha woreda. We used a detailed medical, personal and social history, anthropomorphic measurements and complete physical examination.

Introduction: In Ethiopia, a large percentage of leprosy patients present with established nerve damage. Present techniques for measuring nerve function impairment show no abnormality until 30% of nerve axons are destroyed. Nerve damage in leprosy occurs first in small diameter unmyelinated fibres, then in small myelinated fibres, and much later in large myelinated fibres.

Growth and development of children of mothers with leprosy and healthy controls.

Introduction: In the pre-sulphone and early sulphone years children of leprous parents had been followed in a few prospective studies to observe the development of leprosy. No studies were made of the growth and development of these children.

Methods: A prospective, open-ended, cohort study began in 1975 with follow-up of both mothers and their children until 2003.
