Filter by:The goal of this study is to establish a genetic registry of patients with early-onset motor neuron and neuromuscular diseases. The investigators will collect samples from patients with a motor neuron or a neuromuscular disorder and their family members. The samples to be collected will be obtained using minimally invasive (whole blood) means. The research team will then extract high quality genomic DNA or RNA from these samples and use it to identify and confirm novel gene mutations and to identify genes which regulate the severity of motor neuron/neuromuscular diseases.
The purpose of this study is to evaluate the clinical and radiographic success rate of Miniature pulpotomy with Mineral Trioxide Aggregate (MTA) in primary molars.
The Charcot syndrome Marie Tooth is the most frequent hereditary neuromuscular diseases: there is no curative treatment at present, on the other hand precautionary measures can be taken (physiotherapy, port of splints, orthopaedic surgery and technical assistants). In the literature and in our recent study (evaluation of the pain in the disease of CMT - Reference center of the neuromuscular diseases - CHU Bow) the frequency of the pain is important varying from 66 to 96 % cases, affecting especially hands and lower limbs. The care of the pain in the Charcot syndrome Marie Tooth is not codified. The transcutaneous neurostimulation(TENS) is a not medicinal and not invasive therapeutics, without any brought back collateral effect, used at the same time in the chronic pain and acute since 1960, as well for the neuropathic pains that musculo-scrawny. No study was realized this day on the use of the TENS with analgesic aim in the CMT. We suggest studying the analgesic efficiency of the TENS in the Charcot syndrome Marie Tooth on the pains of lower limbs, the most frequent painful location in our recent works. The main objective will be to analyze the improvement of the pain of lower limbs, based on the decrease of the analogical visual scale(ladder) (EVA), at least 30 %. The secondary objectives will be to estimate repercussions on the functional capacities ( ONLS), the quality of life (SF(sci-fi) 12), the satisfaction (EVA), the global impression(printing) of change ( PGIC), the consumption of analgesic, DN4, NPSI (Neuropathic Pain Symptom Inventory), Concise Questionnaire of the Pains ( QCD), HAD (Hospital Anxiety and Depression scale).
Background: - The third molars (wisdom teeth) normally grow in during late adolescence or early adulthood. Many people need or choose to have these teeth removed with oral surgery. Normally, the removed teeth and tissue are thrown away as medical waste. However, oral health researchers want to collect the teeth and tissue for research. They also want to encourage dentists at the National Institutes of Health to improve their skills in oral surgery. This study will collect the teeth and tissue of people who need to have oral surgery to remove their wisdom teeth. Objectives: - To provide continued dental skills training for dentists at the National Institutes of Health. - To collect teeth and tissue samples following wisdom tooth removal surgery. Eligibility: - Individuals between 16 and 50 who need to have their wisdom teeth removed. Design: - This study will involve a minimum of three visits. There will be a screening visit, a surgery visit, and at least one follow-up visit. - Participants will be screened with a physical exam and medical history. A full dental exam with x-rays will be given to evaluate the need for surgery. - At the second visit, participants will have oral surgery to remove their wisdom teeth. The teeth and tissue removed during the surgery will be collected for study. - Participants will receive drugs to control the pain after surgery. They will also be able to contact a dentist if there are any problems. - Between 7 and 21 days after surgery, participants will have a followup visit to check the healing. If they are having no problems, this will be the last visit. If there are any postsurgery issues, they will be scheduled for additional visits as needed.
The primary goal of this project is to develop and test a Charcot Marie Tooth disease (CMT) Pediatric Scale for use in evaluation in natural history CMT study.
This project includes two projects. One is looking for new genes that cause Charcot Marie Tooth disease (CMT). The other is looking for genes that do not cause CMT, but may modify the symptoms a person has.
This is an observational longitudinal study to determine the natural history and genotype-phenotype correlations of disease causing mutations in Charcot Marie Tooth disease (CMT) type 1B (CMT1B), 2A (CMT2A), 4A (CMT4A), and 4C (CMT4C). The investigators will also be determine the capability of the newly developed CMT Pediatric Scale (CMT Peds scale) and the Minimal Dataset to measure impairment and perform longitudinal measurements in patients with multiple forms of CMT over a five year window
The congenital absence of teeth, commonly referred to as hypodontia or tooth agenesis, is a common developmental anomaly of human dentition that affects approximately 20% of the population. Although new genetic and molecular approaches in humans and mice have increased our understanding of the molecules that control tooth patterning (number, position, shape and size), the precise nature of the genes involved in hypodontia in humans is poorly understood. Hence, understanding the molecular basis for missing teeth is an issue of paramount importance that is both timely and significant to the practice of dentistry. So far, only two genes have been associated with non-syndromic familial tooth agenesis: MSX1 and PAX9. Substitution mutations in the homeodomain region of MSX1 were linked to premolar agenesis while an insertion mutation in the paired box domain of PAX9 was shown to be responsible for molar oligodontia. The long-term goals of this research are to elucidate the molecular pathology of human tooth agenesis, in particular, to evaluate whether genes other than MSX1 and PAX9 (locus heterogeneity) are involved. Alternatively, as in the case of MSX1, it will be interesting to know whether allelic variations, different mutations in these genes, are associated with tooth agenesis. We propose to study a potentially large kindred that report the developmental absence of several posterior teeth. The fundamental hypothesis to be tested states that the gene responsible for the congenital absence of molar teeth in this kindred is a critical element in the genesis of molars. The specific goals are to perform linkage analysis followed by direct sequencing of PCR products to identify the gene and to characterize the nature of the underlying defect. Identifying the underlying gene defect in this family affected by tooth agenesis will add new knowledge to our understanding of the pathogenesis of this defect and will provide the basis for future studies.
