Orphan date December 2008 Enteric neuropathy is a Degenerative disease degenerative neuromuscular condition of the digestive system. In simple terms the Gut zoology gut stops functioning, due to degradation of the nerves and muscles. The condition affects all parts of the digestive tract . There is no known cure or treatment for Enteric neuropathy at this time it is only possible to work on symptom management. The name Enteric Neuropathy only seems to be used for diagnosis within the UK. The most common name worldwide for this condition is Intestinal pseudoobstruction . Symptoms The main symptom of enteric neuropathy is severe and constant pain. Other symptoms include nausea , vomiting , diarrhoea , constipation , bloating and abdominal abnormalities. In addition malabsorption and malnutrition poor nutrition are common, as the digestive system begins to fail. Symptom management is very important and the main priority is usually to get on top of the pain. However, as most people may have been waiting for years for a diagnosis they are often already addicted to Analgesic painkillers such as tramadol and oramorph and these have adverse effects on the primary condition. Diagnosis The diagnosis of enteric neuropathy is rather difficult, in that many symptoms present in ways that are common to many other Bowels bowel and Gut zoology gut related diseases. It is common that many people undergo many surgery surgeries , sometimes over several years, to attempt to combat other possible diseases. The diagnosis itself requires a bowel motility study, which for those who have enteric neuropathy will show signs of severe abnormalities in the movement of the gut. An operation to take a section of muscle for biopsy which, if it shows signs of nerve degradation, confirms the diagnosis.

Ulnar neuropathy may be caused by Ulnar nerve entrapment entrapment of the ulnar nerve at the elbow or wrist with resultant numbness and tingling into the fourth and fifth fingers. Motor function can be assessed by testing for a positive Froments sign, or making an OK sign which the patient will be unable to do . Little finger abduction can be tested as well. Pathophysiology The nerve, axon, and myelin can be affected. Within the axon, fascicles to individual muscles may be involved selectively. Axonal involvement leads to motor unit loss and amplitude area reduction. Conduction block implies impaired transmission through a segment of nerve. In the absence of changes indicating axonal damage, conduction block implies myelin damage to the involved segment. Significant slowing of conduction and or significant spreading out of the temporal profile of the recorded response i.e., abnormal temporal dispersion with preserved axonal integrity suggests demyelination.

Multifocal motor neuropathy MMN is a progressively worsening condition where muscles in the extremities gradually weaken. The disorder, a pure motor neuropathy syndrome, is sometimes mistaken for amyotrophic lateral sclerosis ALS because of the similarity in the clinical picture, especially if muscle fasciculations are present.

Nevertheless, definitive diagnosis is often difficult, and many MMN patients labor for months or years under an ALS diagnosis before finally getting a determination of MMN.

Beginning in childhood or early adulthood, most people with NARP experience numbness, tingling, or pain in the arms and legs sensory neuropathy muscle weakness and problems with balance and coordination ataxia . Many affected individuals also have vision loss caused by changes in the light sensitive tissue that lines the back of the eye the retina . In some cases, the vision loss results from a condition called retinitis pigmentosa . This eye disease causes the light sensing cells of the retina gradually to deteriorate. Learning disabilities and developmental delays are often seen in children with NARP, and older individuals with this condition may experience a loss of intellectual function dementia . Other features of NARP include seizures, hearing loss, and abnormalities of the electrical signals that control the heartbeat cardiac conduction defects . These signs and symptoms vary among affected individuals. Neuropathy, ataxia, and retinitis pigmentosa is a condition related to changes in mitochondrial DNA . Mutations in the MT ATP6 gene cause neuropathy, ataxia, and retinitis pigmentosa. The MT ATP6 gene provides instructions for making a protein that is essential for normal mitochondrial function. Through a series of chemical reactions, mitochondria use oxygen and simple sugars to create adenosine triphosphate ATP , the cell s main energy source. The MT ATP6 protein forms one part subunit of an enzyme called ATP synthase , which is responsible for the last step in ATP production. Mutations in the MT ATP6 gene alter the structure or function of ATP synthase, reducing the ability of mitochondria to make ATP. It remains unclear how this disruption ... more details

Organophosphate induced delayed neuropathy OPIDN , also called organophosphate induced delayed polyneuropathy OPIDP , is a neuropathy caused by killing of neurons in the central nervous system , especially in the spinal cord , as a result of acute or chronic organophosphate poisoning . A striking example of OPIDN occurred during the 1930s Prohibition in the United States Prohibition Era when thousands of men in the American South and Midwest developed arm and leg weakness and pain after drinking a medicinal alcohol substitute. The drink, called Ginger Jake, contained an adulterated Jamaican ginger extract containing tri ortho cresyl phosphate TOCP which resulted in partially reversible neurologic damage. The damage resulted in the limping Jake Leg or Jake Walk which were terms frequently used in the blues music of the period. Europe and Morocco both experienced outbreaks of TOCP poisoning from contaminated abortifacient s and cooking oil , respectively. ref Morgan 1978 Segalla, Spencer 2011 , The 1959 Moroccan Oil Poisoning and US Cold War Disaster Diplomacy, Journal of North African Studies.

This condition is due to mitochondrial dysfunction mediating the death of optic nerve fibers. Dominant optic atrophy was first described clinically by Batten in 1896 and named Kjer s optic neuropathy in 1959 after Danish ophthalmologist Poul Kjer, who studied 19 families with the disease. ref Kjer, P. Infantile Optic Atrophy with Dominant Mode of Inheritance. Copenhagen Bogtrykkeriet Forum pub. 1959. ref Although dominant optic atrophy is the most common autosomally inherited optic neuropathy i.e., disease of the optic nerves aside from glaucoma , it is often misdiagnosed. Synonyms Dominant optic atrophy is also known as autosomal dominant optic atrophy, Kjer type Kjer optic atrophy or, Kjer s autosomal dominant optic atrophy. Clinical presentation Autosomal dominant optic atrophy can present clinically as an isolated bilateral optic neuropathy non syndromic form or rather as a complicated phenotype with extra ocular signs syndromic form . Dominant optic atrophy usually affects both eyes roughly symmetrically in a slowly progressive pattern of vision loss beginning in childhood. Vision testing will reveal scotoma s areas of impaired visual acuity in the central visual field s with peripheral vision sparing and impaired color vision color blindness .
