1. Peripheral neuropathy exacerbation associated with topical 5-fluorouracil.
Match Strength: 6.918
Peripheral neuropathy secondary to 5-flourouracil and capecitabine (Xeloda) has been reported. We report the first case of exacerbation of peripheral neuropathy related to topical 5-flourouracil (Efudex). A 70-year-old Caucasian male with a history of actinic keratosis for 15 years was treated intermittently with topical application of 5-flourouracil. He also developed sensory peripheral neuropathy around the same time, but extensive work-up disclosed no clear etiology. In early 2005, he developed an exacerbation of his peripheral neuropathy following a 21-day course of topical 5-flourouracil ... Read More »

3. G protein beta2 subunit interacts directly with neuropathy target esterase and regulates its activity.
Match Strength: 5.734
Neuropathy target esterase (NTE) was identified as the primary target of organophosphate compounds that cause a delayed neuropathy with degeneration of nerve axons. NTE is a novel phospholipase B anchored to the cytoplasmic face of endoplasmic reticulum and essential for embryonic and nervous development. However, little is known about the regulation of NTE. A human fetal brain cDNA library was screened for proteins that interact with NTE, Gbeta2 and Gbeta2-like I subunits were found to be able to bind the C-terminal of NTE in yeast. The interaction of Gbeta2 and NTE was confirmed by in vivo ... Read More »

4. Increased nodal persistent Na+ currents in human neuropathy and motor neuron disease estimated by latent addition.
Match Strength: 5.247
OBJECTIVE: To investigate the changes in nodal persistent Na(+) currents in human neuropathy and motor neuron disease. In human motor axons, approximately 1.0% of total Na(+) channels are active at rest, termed "persistent" Na(+) channels, and the conductance can be non-invasively estimated by the technique of latent addition in vivo. METHODS: Latent addition was performed in median motor axons of 93 patients with axonal neuropathy (n=38), lower motor neuron disorder (LMND; n=19) or amyotrophic lateral sclerosis (ALS; n=36) and in 27 age-matched normal subjects.

6. Impact of diabetic polyneuropathy and cardiovascular autonomic neuropathy on the excretion of urinary 8-epi-PGF2alpha and its metabolites (2, 3-dinor and 2, 3-dinor-5, 6-dihydro).
Match Strength: 4.627
The objective of this study was to establish if diabetes in the presence of polyneuropathy (PN) and/or cardiovascular autonomic neuropathy (CAN) is associated with alterations in the amounts of 8-epi-PGF2alpha (IP) and its metabolites including 2, 3-dinor-8-epi-PGF2alpha (dinor-IP) and 2, 3-dinor-5, 6 dihydro-8-epi-PGF2alpha (dinor-dihydro-IP) in urine. Mass spectrometric separation showed that excretion of IP was similar in the PN + /CAN- and PN+/CAN+ groups but higher than in the PN-/CAN- group (n = 103, 22 and 60, respectively; P < 0.05). By contrast, excretion of dinor-IP or dinor ... Read More »

7. Effect of over-expression of neuropathy target esterase on mammalian cell proliferation.
Match Strength: 4.446
Neuropathy target esterase (NTE), the human homologue of a protein required for brain development in Drosophila, is expressed primarily in neural cells but is also detected in non-neural cells. Although NTE has been proposed to play a role in neurite outgrowth and process elongation during neurodifferentiation, the function of NTE has not been defined in neural cells. In this study we have investigated the possible role of NTE in neuroblastoma cells and non-neural cells using an over-expression strategy. Over-expression of NTE in human neuroblastoma SH-SY5Y cells and monkey kidney COS7 cells ... Read More »

8. Effects of diabetic neuropathy on body sway and slip perturbation detection in older population.
Match Strength: 4.295
Postural control is a common mechanism to compensate for unexpected displacements of the body. In the older population, a slip or fall due to a failure of postural control is a common cause of morbidity and mortality. The ability of postural control decreases with aging or neuropathy. In this study, 2 groups, diabetics and non-diabetics in the older population, were compared to determine how patterns of postural sway during quiet standing were related to the detection of perturbation. The SLIP-FALLS system was applied to the measurement of sway and detection of perturbation. In phase 1 of the ... Read More »

10. Intravenous paclitaxel administration in the rat induces a peripheral sensory neuropathy characterized by macrophage infiltration and injury to sensory neurons and their supporting cells.
Match Strength: 4.005
Paclitaxel-induced peripheral neuropathy (PN) can be a significant problem for patients receiving chemotherapeutic regimens for the treatment of breast, ovarian, and lung cancer as PN can influence the quality of life and survivorship in these patients. To begin to understand the cellular changes that occur within the peripheral and central nervous system as PN develops, we intravenously infused rats with clinically relevant doses of paclitaxel. Ten days later, behavioral changes indicative of PN became evident that included mechanical allodynia, cold hyperalgesia, and deficits in ambulation ... Read More »

11. Bladder sensation in peripheral nerve lesions.
Match Strength: 3.988
OBJECTIVE: To present bladder sensory data of three common peripheral nerve lesions (e.g., distal, intermediate/focal, and proximal). METHODS: We measured first sensation (FS) and bladder capacity (BC) (not exceeding 600 ml) in 71 patients with peripheral nerve lesions: 35 diabetic neuropathy (D group), 6 post-pelvic surgery (S), and 27 cauda equina syndrome due to lumbar spondylosis (L). We excluded those with detrusor overactivity or low compliance that might affect bladder sensation. RESULTS: The mean FS was 301.7 ml (D), 271.3 ml (S), and 189.4 ml (L), with the largest being in the D group ... Read More »

12. An active dominant mutation of glycyl-tRNA synthetase causes neuropathy in a Charcot-Marie-Tooth 2D mouse model.
Match Strength: 3.911
Of the many inherited Charcot-Marie-Tooth peripheral neuropathies, type 2D (CMT2D) is caused by dominant point mutations in the gene GARS, encoding glycyl tRNA synthetase (GlyRS). Here we report a dominant mutation in Gars that causes neuropathy in the mouse. Importantly, both sensory and motor axons are affected, and the dominant phenotype is not caused by a loss of the GlyRS aminoacylation function. Mutant mice have abnormal neuromuscular junction morphology and impaired transmission, reduced nerve conduction velocities, and a loss of large-diameter peripheral axons, without defects in ...

18. Acute transient encephalopathy following paclitaxel treatment in an adolescent with a recurrent suprasellar germinoma.
Match Strength: 3.047
Paclitaxel is an antineoplastic agent that is used in the treatment of a variety of solid tumors. Dose-limiting side effects of myelosuppression and peripheral neuropathy are well known. Paclitaxel has minimal penetration of the blood-brain barrier and central nervous system side effects are rare. However, transient encephalopathy following paclitaxel infusion has been described in adults but not in children. We present the case of a 14-year-old female with a recurrent suprasellar germinoma who developed an acute encephalopathy 4-6 hr following paclitaxel infusion. Pediatr Blood Cancer (c) ... Read More »

20. Abdominal pain related to mitochondrial neurogastrointestinal encephalomyopathy syndrome may benefit from splanchnic nerve blockade.
Match Strength: 2.738
Patients diagnosed with abdominal pain related to mitochondrial neurogastrointestinal encephalopathy (MNGIE) may benefit from splanchnic nerve blockade. MNGIE, varying in age of onset and rate of progression, is caused by loss of function mutation in thymidine phosphorylase gene. Gastrointestinal dysmotility, pseudo-obstruction and demyelinating sensorimotor peripheral neuropathy (stocking-glove sensory loss, absent tendon reflexes, distal limb weakness, and wasting) are the most prominent manifestations. Patients usually die in early adulthood (mean 37.6 years; range 26-58 years). We report a ... Read More »
