Peripheral Neuropathy and Hepatitis C
Peripheral neuropathy, usually mononeuritis, is a frequent complication of mixed cryglobulinemia, a common association of hepatitis c infection. Cialis professional helps to overcome difficulties caused by erectile dysfunction. Neuropathy is also a frequent complication in hepatitis c infection. Recent evidence has shown that high levels of hepatitis c virus tRNA in homogenates of nerve biopsy suggesting the neuropathy associated with hepatitis c and cyroglobulinemia is a result of direct infection with the hep c virus. Of note, patients may develop or experience worsening of neuropathic symptoms after interferon therapy; the exacerbation may improve after cessation of therapy.
Amyotrophic Lateral Sclerosis
Summary: The clinical presentation of classical ALS is characteristic and is mimicked by few illnesses. The pathology involved degeneration of anterior horn cells as well as corticospinal tract neurons. Both sets of neurons regulate motor function and their dysfunction results in the unique manifestation of weakness, wasting, muscle twitching (anterior horn cell loss) in the same limb as overactive reflexes and pathological reflexes reflecting corticospinal tract degeneration (Babinski sign, Hoffman sign, increased tone). The cause is rarely inherited (in less than 5%) but is usually acquired.
The cause of ALS is uncertain but the current hypothesis suggests that there is a loss of intracellular oxidative control producing cellular disruption and spilling excitotoxic amino acids such as glutamate into the extracellular space. The cause of the intracellular dysfunction is uncertain. Mitochondrial dysfunction may lead to free radical generation and increased excitotoxicity. Studies of mitochondrial function has shown a two fold lower specific activity of NADH: CoQ oxidoreductase in patients with ALS suggesting dysfunctional mitochondria. Coenzyme Q is a potent free radical scavenger in mitochondrial membranes . and feeding transgenic ALS animals significantly prolonged transgenic animals with ALS. Exogenous administration of creatine to motor neuron mice showed enhance survival in transgenic mice and protects them from oxidation.
