Active clinical trials for "Peripheral Nervous System Diseases"

This study was set out 1) Evaluate the impact of Diabetic Peripheral Neuropathy (DPN) and DPN-P (Diabetic Peripheral Neuropathic Pain) on the overall Quality of Life (QoL) in elderly with Diabetic Mellitus (DM) and 2) Evaluate the association between cognition impairments and DM in the elderly, and the contributions of DPN and/or DPN-P

This study establishes reference material of selected lower extremity nerves at pre-defined sites with high-resolution ultrasound. Furthermore in this study, high-resolution ultrasound of patients with common fibular compression neuropathy and patients with type 2 diabetic polyneuropathy involving the common fibular nerve will be examined and compared to healthy controls. High-resolution ultrasound measurements will be correlated with history, clinical information and electrophysiological data.

This is a double blinded two-arm randomized case-only interventional trial. A total of 60 patients who are to receive Paclitaxel to be included and allocated in two groups. The protocol is to be reviewed by the Research Ethics Committee of Faculty of Medicine Cairo University. All procedure will be done in Kasr El-Einy Center of Radiation Oncology and Nuclear Medicine. The first arm (Venlafaxine group) will receive Venlafaxine extended release (37.5 mg) tablets (Zimmerman et al., 2016). The second arm (Memantine group) will receive memantine 10 mg once daily (Morel et al., 2016)

The study aim is to determine the allele frequencies of 1236 G>A and 3435 G>A in ABCB1 and study their association with the incidence and severity of paclitaxel-induced peripheral neuropathy while adjusting for other baseline covariates in Egyptian patients. Additionally, the study aimed at fitting and validating logistic regression models with the aforementioned SNPs evaluated in additive, dominant, overdominant, and recessive genetic models and performing diagnostics for the best model in terms of internal validity.

The purpose of the present study is to systematically test the occurrence of paradoxical and illusory responses to cold and warm stimuli in healthy volunteers with artificial sensory loss.

The purpose of this research study is to create and validate two patient reported outcome (PRO) questionnaires. PRO questionnaires ask questions that help to measure disability in patients with inherited neuropathies. These questionnaires ask questions about what participants think disability is for themselves or others with inherited neuropathies. These questionnaires are a useful tool when evaluating whether treatments are working in the day to day life of an individual, although there are currently no questionnaires available specifically for people who have Charcot Marie Tooth disease (CMT).

Diabetes mellitus can result in damage to the nerves supplying the feet. Various tests can be used to assess nerve damage but no tests so far have been used to assess loss of sweating which can lead to dry skin, fissuring and ulceration. The indicator test (Neuropad) is a plaster which is applied to the sole of the feet just below the 1st and 2nd toes of both feet. If the color of the plaster changes to pink it indicates that there is no nerve damage to the nerves. However if the plaster retains the blue color or the color only partially changes to pink after 600 seconds then this is a positive test and the patient has nerve damage.

To understand pain pathophysiology in terms of risk factors and protective mechanisms ranging from molecular pathways to societal impacts.

Anti-MAG (Myelin Associated Glycoprotein) neuropathy is related to clonal B lymphocyte proliferation producing an monoclonal immunoglobulin (IgM) with anti-MAG activity. IgM may be a reflection of malignant lymphoproliferative syndrome (Waldenström disease) or, more often, monoclonal gammopathy of unknown significance. The anti-MAG antibody has a direct toxicity on the myelin sheath of the peripheral nervous system responsible for a length-dependent demyelinating polyneuropathy. Clinically, this results in a sensitive, ataxic predominant polyneuropathy in the lower limbs, sometimes associated with a tremor of attitude and action tremor of the upper limbs. Clonal B cells at the origin of IgM production may have acquired mutations affecting MYD88 (MYD88 L265P mutation) and CXCR4 (Whim-like CXCR4 mutation). The prevalence of the MYD88 L265P mutation is estimated to be 50% in monoclonal gammopathies of undetermined significance and more than 80% in Waldenström disease. CXCR4 Whim-like mutations are found in 40% of patients with Waldenström's disease. No studies have reported the prevalence of these mutations in patients with anti-MAG neuropathies.

SARS-COV-2 infection reframed medical knowledge in many aspects, yet there is still a lot to be discovered. our aim is to evaluate neurological impact of covid-19; if there is any.
