NeuropathyDiabetic2 more

MEDON aims to examine new methods for early detection and grading of diabetic peripheral neuropathy focusing on both small- and large nerve fibers. Furthermore, MEDON aims to describe differences between people with classic diabetic peripheral neuropathy and those with painful diabetic neuropathy.

Visualize Nociceptor Changes in Neuropathic Human

Chemotherapy-induced Peripheral NeuropathyPeripheral Neuropathy

The purpose of this experiment is to establish a solid medical foundation for the successful development of non-invasive harmonic generation (HGM) microscopic slicing methods. The purpose of this new technology platform is to directly observe the nerve endings of nociceptors To enhance understanding of how neuropathies occur, persistence, and ease. This technique will assist in the diagnosis and prognosis of patients with neuralgia.

Carpal Tunnel SyndromeCharcot-Marie-Tooth Disease1 more

The purpose of this study is to learn about focal compressive median neuropathy at the wrist (Carpal Tunnel Syndrome) and outcomes of therapies (e.g. conservative and surgery) in the upper extremities of patients diagnosed with an inherited neuropathy. All patients enrolled in the Rare Diseases Clinical Research Network (RDCRN) Inherited Neuropathies Consortium (INC) Contact Registry who have marked one of the following disorders: CMT1A, CMT1B, CMT2A, CMT4, CMTX, other known CMT peripheral neuropathy, other unknown CMT peripheral neuropathy, or Hereditary Neuropathy with liability to Pressure Palsies (HNPP), will be invited via email to participate in this online study.

Complementary and Integrative Therapy for Diabetic Neuropathy

Diabetes MellitusType 21 more

Despite the long tradition of complementary and alternative medicine (CAM) therapies there are hardly any interventional trials on type 2 diabetes mellitus. Hence this pilot study aims to investigate the influence of a two weeks integrative inpatient therapy on the quality of life in 50 patients suffering from diabetic neuropathy. Integrative treatment includes aspects of conventional and traditional European and Chinese medicine, mind-body medicine, physical therapy and lifestyle modification (nutrition advices, stress management and exercise training). The observational design intends four measurement points: tree months before (T0), directly before (T1), directly after treatment (T2) and three months follow-up (T3). The subjective evaluation of the neuropathy-related quality of life was combined with neurophysiologic instruments (QST), to measure neuropathic symptoms. Also pain intensity, locus of control, interpretation of illness, coping style, anxiety/depression, life satisfaction and several biomarkers (HbA1c, ABI, WHR and BMI) are measured. In addition a qualitative interview should give a view to patient perspective of therapy process.

Fall Risk Assessment in People With Diabetic Neuropathy

Diabetic Peripheral Neuropathy

Fall risk is increased in people with diabetic peripheral neuropathy (DPN) and yet, minimal research has been conducted to identify appropriate fall risk assessment tools and improve our understanding of falls in these individuals. Purpose: The primary purpose of this study is to establish a foundation of knowledge needed to address falls in people with DPN. This will be accomplished through 1) comparing the validity of 4 fall risk assessment tools, 2) identifying risk factors for falls and 3) determining how quality of life is influenced by factors related to falls in people with DPN.

Evaluation of Neuromuscular Disease

HealthyNeuromuscular Disease1 more

The peripheral nervous system is the portion of the nervous system outside of the brain and spinal cord. It includes the 12 pairs of cranial nerves, 31 pairs of spinal nerves and their branches, nerves responsible for sensation and maintenance of normal body functions (sympathetic and parasympathetic nerves). Years of research using clinical examinations, microscopic examinations, and electrophysiology have made the peripheral nervous system the best-studied and most available portion of the nervous system. However, even with all of the extensive studies conducted on the peripheral nervous system, many conditions remain unclassified. The EMG Laboratory at the NIH concentrates on studying disorders of the peripheral nervous system. This protocol was designed to allow the EMG Laboratory to; I) Learn more about established diseases of the peripheral nervous system II) Identify and characterize new diseases of the peripheral nervous system III) Assess current techniques in the diagnosis of diseases of the peripheral nervous system IV) Refine old methods and develop new ones for the diagnosis of diseases of the peripheral nervous system.

Neurotoxic Health Hazards of Long-Term Low-Level Exposure to Organophosphate (OP) Compounds in in...

Peripheral Neuropathy

During 1987-1991, WHO supported studies of exposures and short term neurobehavioral effects in a cohort (n=200) with occupational and community exposures to pesticide drift containing organophosphates from orchards and cotton fields in the Hula Valley. We aim (1) to re-examine neurobehavioral outcomes in members of the original cohort and (2) to examine cognitive effects in children with residential exposures. In adults, we will carry out assays of alkyl phosphates, PON1 (paraoxonase-1), NTE (Neuropathy Target Esterase), neurobehavioral tests of cognitive and performance skills, nerve conduction measurements and mood status. We will carry out Psycho-Didactic tests in children. The findings will advance knowledge on delayed term health effects of lengthy everyday exposure to OP pesticides and guide regulatory policy.

Diabetic Neuropathy Screening Study 1.1 + Substudy 1.2-1.3-1.4

Diabetic NeuropathiesDistal Peripheral Sensory Neuropathy4 more

The overall objective of this project is to describe the prevalence of and risk factors to diabetic neuropathy in a representative cohort of diabetes patients and to investigate pathophysiological conditions in those patients with neuropathy. This project will yield substantial new knowledge about the prevalence of diabetic neuropathy in type 1 and type 2 DM persons, new risk factors to neuropathy and the association to other diabetic complications. Findings related to the study may facilitate new treatment regimens prompting a better neuropathy treatment with reduced incidence of diabetic complications. First patients at SDCC will be screened for diabetic neuropathy (Study 1.1) with an extended neuropathy screening program as an addition to the routine neuropathy screening at SDCC. 1000 patients with type 1 DM and 1000 patients with type 2 DM will be included. This screening study is a prerequisite for the further study of study participants in substudies investigating associations between diabetic neuropathy and diabetic complications as described below. Hypothesis: Several patients with diabetes have undiagnosed neuropathy and associated diabetic complications. We hypothesize that diabetic neuropathy is underdiagnosed at SDCC and can be diagnosed with targeted screening with new and traditional measuring techniques. In addition, several patients may have complications related to neuropathy, including foot complications, and dysregulation of glucose metabolism Aim: This study consists of a screening study (study 1.1) and two substudies (1.2 and 1.3 ). Study 1.1 is a cross-sectional study describing the prevalence of diabetic neuropathy based on questionnaire data and objective measures as described below and associated diabetic complications including foot complications. The primary aim is to explore the prevalence of diabatic neuropathy in patients with type 1 and type 2 DM at SDCC and secondarily to explore associations between diabetic neuropathy and complications, as described in the respective sections below. The substudy 1.2 is an observational single center cohort study with the aim of investigating associations between neuropathy diagnosed with new devices for measurement of neuropathy and foot complications in patients with type 1 and type 2 diabetes. The substudy 1.3 is an observational single center cohort study investigating the association between CAN and glycemic variability in patients with type 1 diabetes.
