Filter by:The purpose of this study is to describe midfacial segment pain phenotype, burden and comorbidities in a multicentre and multidisciplinary setting. The ultimate goal is a comprehensive description of this type of pain allowing for its implementation in future classifications. This cross-sectional study is designed to describe midfacial segment pain in a clinical setting. Patients from rhinologic, headache and facial pain or oral medicine/dentistry secondary care centres will be recruited during a one year period. Individuals with other facial pain according to current classification such as sinonasal disorders, neoplasms, local infections, history of significant trauma associated with pain onset will be excluded. Data will be collected through a structured questionnaire covering pain characteristics, coexisting diagnoses, pain-related burden and consequences, physical examination and paranasal sinuses imaging.
- 20 patients will be divided into 2 groups - Group 1 : in which conventional appliance will be constructed after alginate impression - Group 2 : in which 3d printed appliance will be constructed after intra-oral scanning
Patients with orofacial pain lasting at least 3 months. The patients will be randomly assigned to one of the two groups according to the treatment method: group I (intraoral injection) and group II (transcutaneous injection) where each patient injected Botox at each trigger point according to the treatment group by the same operator. Patients will be examined by a blinded investigator at pre- and post-injections at the following intervals: during diagnosis, 1 week, 4, and 6 weeks post-injection. The patients will be assessed using a pain score measured on a 10-point visual analog scale (VAS). The secondary outcome assessed will be measuring the quality of life in an Oral Health Impact Profile questionnaire (OHIP-14).
Research question: Dose the use of oral zinc supplement improve the effects of botulinum toxins injection in patients with myofascial pain dysfunction syndrome? Statement of the problem: MPDS Patients treated with botulinum toxin A injection usually suffers from return of the symptoms which requires successive injections almost every (3-4M) Rationale for conducting the research: The concept of adding the zinc supplementation prior to BTXA injection is contributed to the fact that botulinum toxin is a zinc-dependent metalloprotease; therefore, every botulinum toxin molecule must be accompanied with a zinc molecule to effectively paralyze a muscle. However, commercially available BTXA preparations exclude zinc from their preparations, and BTX clinical efficiency and duration varies according to the zinc levels of the patient. Although the BTX effect could remain for several months, its zinc-dependent proteolytic activity befalls within hours of administration before the toxins are degraded in the tissues. Therefore, for achieving better results from BTX, the recipients should have adequate zinc levels at the time of administration. Therefore, oral zinc supplement intake prior to BTXA injection may enhance its clinical efficiency and duration. botulinum neurotoxins are the most potent toxins known. They bind to nerve cells, penetrate the cytosol and block neurotransmitter release. Comparison of their predicted amino acid sequences reveals a highly conserved segment that contains the HExxH zinc binding motif of metalloendo peptidases. The metal content of tetanus toxin was then measured and it was found that one atom of zinc is bound to the light chain of tetanus toxin. Zinc could be reversibly removed by incubation with heavy metal chelators. Zn2+ is coordinated by two histidines with no involvement in cysteines, suggesting that it plays a catalytic rather than a structural role. Bound Zn + was found to be essential for the tetanus toxin inhibition of neurotransmitter release in Aplysia neurons injected with the light chain. The intracellular activity of the toxin was blocked by phosphoramidon, a very specific inhibitor of zinc endopeptidases. Purified preparations of light chain showed a highly specific proteolytic activity against synaptobrevin, an integral membrane protein of small synaptic vesicles. The present findings indicate that tetanus toxin, and possibly also the botulinum neurotoxins, are metalloproteases and that they block neurotransmitter release via this protease activity. So The use of zinc supplementation prior to BTXA injection has been suggested by several previous studies to prolong its duration of action as well as improve its efficacy
Orofacial pain is diagnosed for more than 1.9 percent of general population and for 0.3 percent origin of the facial pain is unknown. Commonly atypical facial pain is treated as a neurological condition without an emotional or psychiatric evaluation. Since atypical pain and mood affective disorders can be related, patients do not receive proper care for this condition. The aim of this study is to evaluate the relationship between atypical facial pain syndrome and affective mood disorders. We aim to assess patients' with no diagnosed organic pathology tendency towards anxiety, depression, sleep disorders and one of big five personality traits through self-rating questionnaires. We will compare the gathered data with biosensors from iMotions software.
