Certain organophosphorus esters such as diisopropylfluorophosphate (DFP) cause delayed neuropathy by inhibition of neuropathy target esterase (NTE) keeping neuron in normal function. In this study, effects of neurobion alone and in combination with dexamethasone on DFP–induced delayed neuropathy were evaluated. Thirty-five mice were divided to five groups that each group consists 7 mice. Except...

Pneumocephalus is a common occurrence after cranial surgery, with patients typically remaining asymptomatic from a moderate amount of intracranial air. Postsurgical pneumocephalus rarely causes focal neurological deficits; furthermore, cranial neuropathy from postsurgical pneumocephalus is exceedingly uncommon. Only 3 cases have been previously reported that describe direct cranial nerve compre...

The cause of peripheral neuropathy associated with tuberculosis is controversial. Possibilities include an immune mediated neuropathy, direct invasion of nerves, vasculitic neuropathy, compressive neuropathy, a meningitic reaction, and the toxic effects of antituberculous chemotherapy. This report describes the unusual finding of granulomas in the peripheral nerve of a patient with tuberculosis...

Organophosphate induced delayed neuropathy (OPIDN) is an uncommon clinical condition. It occurs in association with the ingestion of great amounts of organophosphate after the stimulation of cholinergic receptor. The clinical picture is characterized by a distal paresis in lower limbs associated with sensitive symptoms. Electrodiagnostic studies show a motor axonal neuropathy. Involvement of th...

BACKGROUND Organophosphates (OPs) represent the most widely used class of pesticides. Although perceived as low toxicity compounds compared to the previous organochlorines, they still possess neurotoxic effects both on acute and delayed levels. Delayed neurotoxic effects of OPs include OPIDN and OPICN. The mechanisms of these delayed effects have not been totally unraveled yet. One possible con...

We have previously demonstrated an abnormally delayed mean brake response time and an increased frequency of abnormally delayed brake responses in a group of neuropathic diabetic drivers compared with a control group of drivers with neither diabetes nor lower extremity neuropathy. The objective of the present case-control study was to compare the mean brake response time between neuropathic dia...

Brain neuropathy target esterase (NTE), associated with organophosphorus (OP)-induced delayed neuropathy, has the same OP inhibitor sensitivity and specificity profiles assayed in the classical way (paraoxon-resistant, mipafox-sensitive hydrolysis of phenyl valerate) or with lysophosphatidylcholine (LysoPC) as the substrate. Extending our earlier observation with mice, we now examine human eryt...
