Medication-induced exacerbation of neuropathy in Charcot Marie Tooth disease.

Toxin or medication-induced worsening of preexisting peripheral neuropathy is a generally accepted but not well-studied phenomenon in humans. Drug-induced exacerbation of Charcot Marie Tooth disease (CMT) neuropathy is a common concern; a list of potential drugs to avoid is maintained by the CMT Association but with limited direct evidence or advice on relative risk. An extensive literature search for reported cases of drug effects in CMT patients found the vast majority concerned excessive vincristine toxicity in patients with undiagnosed demyelinating forms of CMT, many after 1 or 2 doses.

The diabetic neuropathies.

Background: Diabetes remains the most common cause of neuropathy in the United States and is a significant source of morbidity and mortality, accounting for substantial suffering and billions of dollars in health care expenditures each year.

Review Summary: Our insight into the pathophysiology of the diabetic neuropathies has increased considerably over the last decade. aided by advances in the basic science of diabetes itself.

Diabetic neuropathy: clinical features, etiology, and therapy.

Diabetes mellitus is a common cause of peripheral nervous system disorders that manifest in a variety of clinical forms, many of which are often misdiagnosed. Over the past two decades, our understanding of the pathophysiology of diabetic nerve injury has improved remarkably through the elucidation of the important roles of the polyol pathway of glucose metabolism, oxidative injury, advanced glycosylation end-products, vascular insufficiency, and other mechanisms. A large number of clinical treatment trials based upon this abundant scientific data have met with limited success, but ongoing and future trials offer promise for more dramatic success in treating this common cause of morbidity and mortality in the diabetic population.

DNA biomarkers antecede semiquantitative anthracycline cardiomyopathy.

Adriamycin (ADM, or doxorubicin hydrochloride) is an effective antineoplastic agent whose use is restricted by its well-described, dose-dependent cardiotoxicity. This study measures ADM DNA adduct formation by 32P-radiolabeling DNA, enzymatically digesting radiolabeled DNA, separating the formed adducts on two-dimensional thinlayer chromatography (2D-TLC), and quantitating the adducts with autoradiography and densitometry. Thirty-six male Sprague-Dawley rats are randomized to receive ADM at varying intraperitoneal (i.

Unilateral auditory neuropathy: case study.

This article reports on an 11-year-old boy who was diagnosed with unilateral auditory neuropathy. After failing his annual medical and school hearing screenings, he was referred for audiologic testing, which identified a profound sensorineural hearing loss in his left ear that has remained stable for the past 3 1/2 years. Subsequently, otoacoustic emissions revealed findings that were consistent with an auditory neuropathy.
