Use of Hyaluronic Acid in Osteoarthritis of Temporomandibular Joint in Adolescent Patient

Osteoarthritis is a type of articular origin Temporomandibular disorders, being one of the most common degenerative processes affecting the temporomandibular joint. It is characterized by remodeling of the underlying subchondral bone, deterioration and abrasion of articular tissue. Intra-arti- cular injections of hyaluronic acid are considered beneficial for treatment of pain and recovery of joint tissues properties. The aim of this article is to describe the use of hyaluronic acid in the management of osteoarthritis of temporomandibular joint in an adolescent patient. Female patient, 15 years old, presented pain with a year of progress in the bilateral preauricular region, with increased pain at maximum aperture. Considering the clinical and imaging tests the patient was diagnosed with disk displacement with reduction with bilateral osteoarthritic and inflammatory component. Mandibular rest, liquid diet, NSAIDs were indicated and the application of intra-articular hyaluronic acid (Suprahyala 25 mg / 2.5 ml) bilaterally. Control was quoted at 2, 3 and 16 weeks where the patient has no spontaneous pain and tenderness. The use of hyaluronic acid is one of the most commonly used therapeutic alternatives for the management of osteoarthritis of temporomandibular joint. However, further evidence of its use in intra-articular application in adolescents and children should be incorporated

Dolor miofascial en el territorio craneocervical: una revisión de la patología y su relación con polimorfismos genéticos del sistema GABAérgico

El dolor miofascial es una patología muscular regional no inflamatoria caracterizada por la presencia de una zona hiperirritable de tejido muscular que se encuentra en una banda tensa, denominado punto gatillo. En la región orofacial pertenece a un conglomerado de patologías denominadas trastornos temporomandibulares, correspondiendo al de mayor prevalencia. Las manifestaciones clínicas van desde dolor local, tensión muscular y disfunción estructural hasta dolor referido, fenómenos autonómicos e hiperexcitabilidad en el sistema nervioso central. Durante las últimas décadas se han asociado variantes genéticas con diferentes expresiones en patologías dolorosas, algunas de las cuales se encuentran en el sistema GABAérgico. En el presente artículo se realiza una revisión del dolor miofascial como patología y su relación con estos polimorfismos genéticos

Enhancing the removal of hazardous pollutants from coke making wastewater by dosing activated carbon to a pilot‐scale activated sludge process

Powdered activated carbon (PAC) was investigated for its ability to remove 6 polycyclic aromatic hydrocarbons (Σ6PAHs) (fluoranthene, benzo[b + J]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, indeno[1,2,3-cd]pyrene, benzo[g,h,i]perylene), trace metals and colour from coke making wastewater when dosed to a pilot-plant activated sludge process (ASP). The ASP had a volume of 0.68 m3 and was operated to simulate the full-scale ASP treating coke wastewater from a steel works. Operational conditions included a flow rate of 0.78 m3/day, a hydraulic retention time of 21 hours, a sludge retention time of 38 days and a temperature of 27°C. The ASP was operated for a control period before PAC was dosed directly into the aeration cell at a dose of 400 mg/L. Powdered activated carbon addition resulted in a 20% increase in removal efficiency of the Σ6PAHs. Removal efficiency of trace metals was variable, but increased for nickel, chromium and cadmium by 22.6%, 20.5% and 12.4%, respectively. Improvement in colour removal efficiency was marginal at 5%. PAC addition allowed the improvement of treatment efficiencies in the ASP process at relatively low capital and operational costs, which may assist in reaching tighter effluent emission limits set for the industry
