Filter by:Our primary objective in this study is to investigate the cutaneous silent period (CSP) in normal subjects in the Egyptian population, as it was not carried out before in Egypt. The aim was to carry out the test in our unit to study the appropriate method, technique, and parameters of this new test so that we can apply it in future research. In addition, to obtain preliminary normative data of the test; onset latency, end latency, duration, and latency difference (LD) of CSP, as well as assess the effect of age, height, upper limb length, and gender on CSP values.
In order to meet the challenge of an unambiguous diagnosis and effective therapy of SFN or the prognosis of susceptibility to the development of SFN, this project aims to create a data basis on which software will be developed during the project. This software should later be able to combine (integrate) quantifiable biometric data collected from the patient (both objectively measured and patient reported parameters) with the results of biological analyses of the patient's own nerve cells from stem cells. We expect that the patient-specific combination and correlation of biometric and biological data can lead to a significant improvement in the diagnosis, prognosis and therapy of chronic pain. The initial data collection required for the development of such a software (Bio2Integrate) will be carried out in three different project parts: Bio2Watch, Bio2Patient and Bio2Cell
Small fiber neuropathy affects millions of peoples worldwide. The neuropathy is causing disabling burning pain and dysautonomia such as dizziness with standing, brain fog, fatigue, constipation, too much or too little sweating. The detection of nerve damage is complicated and not widely available; it requires either skin biopsy or specialized equipment and training. This project utilizes the mathematical processing of skin pictures for the purpose to extract the statistical features related to loss of small fibers. This approach can improve the availability of diagnosis of small fiber neuropathy.
The study aims to compare different methods to assess thermal detection ability in diabetic patients, as a way to monitor and diagnose neurological complications of diabetes mellitus.
We examine patients with different autonomic neuropathies and Ehlers Danlos syndromes compared to healthy controls at three different points over time (baseline, after 3 months and after 1.5 years) to gain knowledge about the course of this disease and understand its pathophysiology, with a focus on Small Fiber neuropathy. Moreover we will validate the german version of the Malmö POTS Score and establish an easy diagnostic scheme for patients in outpatient care.
Small fiber neuropathy (SFN) is an injury of cutaneous nerve fibers, mainly by a decrease in their density within the cutaneous tissue. The symptomatology associated with this SFN is broad with symptoms that are essentially sensory, but also autonomic. The etiologies of SFN are numerous (diabetes, drug, infectious, immunological...) and clinically non-specific, justifying a broad etiological assessment. The appearance of staged skin biopsies in the SFN balance sheet has greatly helped to improve diagnosis. Despite this, a significant part of SFN remains without associated etiology and is considered idiopathic. As the distribution of the different causes of SFN remains a missing data to date, the completion of this cohort study by one of the SFN reference centres should make it possible to establish the prevalence of SFN causes over a large population. Only patients with clinical symptoms that may be related to SFN and who have been sampled for SFN, positive or not, will be eligible for recruitment. The result of the anatomopathological sampling will allow patients to be separated into two groups, with or without SFN. The main judgement criteria will be the prevalence of etiologies associated with SFN: diabetes, medication, systemic lupus erythematosus, Gougerot-Sjögren syndrome, amylosis, dysthyroidism, alcoholism, vitamin B12 deficiency, HIV infection, hepatitis C, paraneoplastic syndrome, hereditary disease (Fabry disease, Friedreich ataxia,...), idiopathic, others.
The investigators will treat patients (targeting enrollment of n=20) who suffer from trigeminal or glossopharyngeal nerve pain in the context of painful small fiber neuropathy. The primary pain-related objective is reduction of pain and reduced use of rescue and other anti-pain medications. Another goal is to monitor and confirm the safety profile established in the migraine population, during previous Phase 3 trials.
This study will enroll patients with small fiber neuropathy (SFN). The study will look at an intravenous immunoglobulin (IVIG) called Panzyga. Panzyga is approved by the FDA as a therapy for Primary humoral immunodeficiency (PI) in patients 2 years of age and older; Chronic immune thrombocytopenia (ITP) in adults and Chronic inflammatory demyelinating polyneuropathy (CIDP) in adults. It has not been approved by the FDA for use in SFN. There is mounting evidence that Intravenous Immunoglobulin (IVIG) can cause pain reduction and improve objective nerve fiber densities on skin biopsies in great numbers in SFN patients. The primary outcome is quantified improvement in intraepidermal nerve fiber density (IENFD) on repeat skin punch biopsy after 6 months of IVIG treatment.
To detect small fiber neuropathy in patients with possible or established diabetic peripheral neuropathy (DPN) by skin biopsy and explore clinical characteristics and pathological features in Chinese patients with diabetes.
This study will evaluate the effects of a nutritional supplement called nicotinamide riboside in preventing small fiber nerve degeneration that is experimentally induced by applying capsaicin to skin in otherwise healthy study participants. Furthermore, the effects on nerve regeneration will also be evaluated. The results will be compared to a placebo control drug.
