Correlation between parafunctional habits and temporomandibular dysfunction: Systematic review / Correlção entre hábitos parafuncionais e disfunção temporomandibular: Revisão sistemática

Introduction: Temporomandibular dysfunction (TMD) is a term belonging to the orofacial pain group that affects the masticatory muscles, temporomandibular joint and adjacent structures. TMD can be triggered by parafunctional habits, which are actions performed without specific natural function of the human being, becoming risk factors. Objectives: To evaluate through a literature review the correlation between parafunctional habits and temporomandibular dysfunctions. Methods: The articles were researched in the PubMed and Scielo databases, from 2009 to 2019. As inclusion criteria: articles published in English and Portuguese with the key words "Temporomandibular Joint", "Parafunctional Habits" and "Temporomandibular Dysfunction". Themes that were not related to the theme were excluded. Results: Eight articles were selected, in which six of them correlated the parafunctional habits with the signs and symptoms of TMD. Through these studies, it was seen that people develop a painful symptomatology, affecting even quality of life. In parallel, through other articles, there is a possible relationship between the intensity of physical activity with the degree of TMD found, and also the emergence of certain habits after certain surgeries. Conclusion: It is remarkable the correlation between the various parafunctional habits and TMD. Thus, the dentist should be paid, during diagnosis, to their presence and consider, as part of the treatment, guidelines for the reduction of these habits, obtaining success in controlling dysfunction

Diagnóstico diferencial nos casos de compressão vásculo-nervosa X DTM em pacientes desdentados totais: descrição de caso clínico / Differential diagnosis in cases of venous-nervous compression X TMJ in total edentulous patients: clinical case description

Introdução: atrofia de rebordo alveolar na mandíbula é uma sequela comum da perda total da dentição. a atrofia progride causando desconforto e comprometimento de função e estética. durante reabsorção óssea alveolar, o forame mentoniano aproxima-se da crista alveolar, esta situação pode ter como consequência uma compressão vásculo-nervosa ocasionando desde parestesia no lábio inferior até sintomatologia dolorosa na região, semelhante à dor paroxística de uma neuralgia trigeminal. provocada pela compressão da prótese no rebordo. objetivo estabelecer critérios para o diagnóstico diferencial da dor causada pela compressão do rebordo alveolar inferior por prótese total. caso clinico: M.A.S., gênero feminino, 75 anos, procurou a clínica odontológica com queixa de dor no ouvido esquerdo ao mastigar. relatou diagnóstico de neuralgia trigeminal e tomar carbamazepina prescrita pelo médico sem melhora. no exame clínico verificou-se que a mesma usava prótese total. na palpação dos músculos da mastigação não foi encontrado ponto gatilho. esta palpação não reproduziu a dor relatada pela paciente. foi solicitado que a remoção das próteses e realizado palpação da área do rebordo inferior. ao se palpar a área superior antero-lateral do rebordo alveolar inferior, área da saída do nervo mentual, gerou a dor familiar queixa principal da paciente. foi realizado alívio da prótese inferior na área geradora da dor, e reembasamento com material resiliente. provável emergência do nervo mentual. Conclui-se, que a necessidade de cuidadoso exame físico e anamnese são necessários para o diagnóstico diferencial entre DTM e dor causada por compressão vascúlo-nervosa no nervo mentual em pacientes desdentados totais. Além da palpação dos músculos da mastigação, a palpação do rebordo alveolar é essencial para reproduzir a dor familiar, e estabelecer o diagnóstico diferencial e condutas de tratamento

Uso do laser de baixa potência no tratamento de disfunção temporomandibular muscular - revisão sistemática/ Low-power laser use for tratment of temporomandibular muscle dysfunction: a systematic review

Objetivo: Realizar uma revisão sistemática sobre a eficácia do uso do Laser de Baixa Potência em pacientes com disfunção temporomandibular muscular. Método: Realizou-se uma busca de artigos nas bases de dados PubMed e Scielo, buscando estudos clínicos realizados em humanos, artigos que relatam o uso do Laser de Baixa Potência  em tratamentos e o seu acompanhamento, publicados nos idiomas português e inglês, até o ano de 2019 com os descritores “Low-level”, “Laser Therapy”, “Myofascial Pain” e “Temporomandibular Dysfunction”. Foram excluídos artigos que não apresentavam clareza na metodologia ou não se adequavam à temática pesquisada. Resultados: Após a triagem sete artigos foram selecionados, nos quais os resultados apontaram que laser de baixa potência pode ser utilizado como uma modalidade de tratamento no controle da disfunção temporomandibular dolorosa, possibilitando redução da intensidade de dor à palpação, melhora da percepção subjetiva da dor e da movimentação mandibular, podendo-se observar também efeitos positivos em aspectos psicológicos em pacientes com dor orofacial crônica. Conclusão: De acordo com os estudos antepostos, o uso do Laser de Baixa Potência tem demonstrado em curto prazo, eficácia no auxilio da abertura bucal dos pacientes analisados, permitindo o alivio nas dores dos pacientes, possibilitando melhor qualidade de vida. Contudo, ainda não é um consenso na literatura sobre os melhores parâmetros específicos para gerar efeitos mais satisfatórios. Assim, são necessários mais estudos para desenvolver uma confirmação precisa dos resultados e avaliação de outras doses e protocolos

Rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART): Study protocol for a randomized controlled trial

Background: Acute respiratory distress syndrome (ARDS) is associated with high in-hospital mortality. Alveolar recruitment followed by ventilation at optimal titrated PEEP may reduce ventilator-induced lung injury and improve oxygenation in patients with ARDS, but the effects on mortality and other clinical outcomes remain unknown. This article reports the rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART). Methods/Design: ART is a pragmatic, multicenter, randomized (concealed), controlled trial, which aims to determine if maximum stepwise alveolar recruitment associated with PEEP titration is able to increase 28-day survival in patients with ARDS compared to conventional treatment (ARDSNet strategy). We will enroll adult patients with ARDS of less than 72 h duration. The intervention group will receive an alveolar recruitment maneuver, with stepwise increases of PEEP achieving 45 cmH(2)O and peak pressure of 60 cmH2O, followed by ventilation with optimal PEEP titrated according to the static compliance of the respiratory system. In the control group, mechanical ventilation will follow a conventional protocol (ARDSNet). In both groups, we will use controlled volume mode with low tidal volumes (4 to 6 mL/kg of predicted body weight) and targeting plateau pressure <= 30 cmH2O. The primary outcome is 28-day survival, and the secondary outcomes are: length of ICU stay; length of hospital stay; pneumothorax requiring chest tube during first 7 days; barotrauma during first 7 days; mechanical ventilation-free days from days 1 to 28; ICU, in-hospital, and 6-month survival. ART is an event-guided trial planned to last until 520 events (deaths within 28 days) are observed. These events allow detection of a hazard ratio of 0.75, with 90% power and two-tailed type I error of 5%. All analysis will follow the intention-to-treat principle. Discussion: If the ART strategy with maximum recruitment and PEEP titration improves 28-day survival, this will represent a notable advance to the care of ARDS patients. Conversely, if the ART strategy is similar or inferior to the current evidence-based strategy (ARDSNet), this should also change current practice as many institutions routinely employ recruitment maneuvers and set PEEP levels according to some titration method.Hospital do Coracao (HCor) as part of the Program 'Hospitais de Excelencia a Servico do SUS (PROADI-SUS)'Brazilian Ministry of Healt

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
