Objective: To evaluate the pulpal temperature changes due to the polymerisation of resin and glass ionomer-based materials in dentine thicknesses in immature permanent teeth with open apices. Material and Methods: Forty extracted sound human third molar teeth with open apices were included. The width of the cavities prepared on the occlusal surface was 4×5 mm. The depth was 2 mm in the resin groups. 4 mm in the groups in which glass ionomer liner was applied before composite restoration. The coronal parts of the samples were then placed on an acrylic plate with three gaps for feeding-extraction needles and the thermocouple. The temperature changes were recorded. The data was analyzed by SPSS. Statistical significance was accepted as p

Resumo Fundamento A Terapia Antiplaquetária Dupla (DAPT, do inglês dual antiplatelet therapy) é o tratamento de escolha para pacientes com síndromes coronarianas agudas e crônicas, uma vez que ela reduz mortalidade e previne complicações trombóticas recorrentes. A avaliação da carga isquêmica e do risco de sangramento é crucial na escolha da DAPT e de sua duração. Objetivos O objetivo de nosso estudo foi conduzir um acompanhamento clínico prospectivo de pacientes recebendo terapia combinada (AAS 75mg + clopidogrel 75 mg). Nosso estudo é um estudo multicêntrico, transversal, observacional, do tipo coorte. Métodos Foram incluídos 1500 pacientes que iniciaram DAPT combinada para o tratamento de síndrome coronariana aguda ou síndrome coronariana crônica. Os desfechos primários foram internação hospitalar por qualquer motivo, internação por causa cardiovascular, infarto agudo do miocárdio, trombose de stent, revascularização de vaso alvo e sangramento; os desfechos secundários foram morte por qualquer razão ou por causa cardiovascular e acidente vascular cerebral. O nível de significância adotado na análise estatística foi 5%. Resultados A idade mediana foi 63 anos; 78,5% dos pacientes estavam recebendo DAPT por síndrome coronariana aguda. As taxas de internação por causas cardiovasculares, de infarto agudo do miocárdio, de trombose de stent e de revascularização de vaso alvo foram 7,9%, 2,3%, 1,3% e 4,2%, respectivamente. Enquanto a taxa de sangramento segundo a escala BARC tipo 1 foi de 3,3%, a taxa de sangramento BARC tipo 5, 3, ou 2 foi 0,6%. As taxas dos desfechos secundários morte por qualquer razão, morte por causa cardiovascular e acidente vascular cerebral foram 0,5%, 0,3% e 0,3%, respectivamente. Conclusão Nosso estudo mostrou que a DAPT em regime combinado de doses fixas de AAS e clopidogrel é eficaz e seguro em pacientes com síndrome coronariana aguda ou crônica adequadamente selecionados.

Abstract Background: A single dose injection or continuous infusion of local anesthetics into the joint space is considered to be a well-defined analgesia technique. The aim of this study was to investigate the chondrotoxic and apoptotic effects of single-dose intra-articular injection of levobupivacaine and bupivacaine on rabbit knee joint tissues. Materials and methods: The animals were allocated into two groups each containing 20 rabbits. 0.5% levobupivacaine (Group L) and 0.5% bupivacaine (Group B) were applied intra-articularly to the left posterior joints of rabbits. At the same time, normal saline was applied to the right posterior leg knee joints of rabbits in both groups and used as a control (Group S). At the end of the 7th and 28th days after the intraarticular injections, ten randomly chosen rabbits in each group were killed by applying intraperitoneal thiopental. Sections of cartilage tissue samples were stained for light microscopic examinations and the TUNEL method was used to investigate apoptotic cells. Results: As a result of immunofluorescence microscopic examination, the number of apoptotic cells in Group B at day 7 and day 28 were both significantly higher than Group L and S (p < 0.05). Also, the number of apoptotic cells in Group L at day 7 and day 28 were both significantly higher than Group S (p < 0.05). Conclusions: We found that bupivacaine is more chondrotoxic than other anesthetic agent and increases the number of apoptotic cells. These results indicated that bupivacaine caused high chondrotoxic damage and it led to more apoptotic activation than levobupivacaine.
