Objetivo:O objetivo deste estudo foi investigar o fenótipo do HLA em pacientes com contratura de Dupuytren (CD) para verificar a correlação desses alelos com os fatores de risco para o desenvolvimento da CD na população brasileira.Métodos:Este foi um estudo de caso-controle de 25 pacientes com CD e 443 indivíduos saudáveis sem histórico de doenças associadas ao HLA. As tipagens classe I e classe II do HLA foram feitas utilizando o método iniciador de sequências específicas da reação em cadeia da polimerase.Resultados:O fenótipo HLA-B*18 foi observado em 32% dos pacientes e 10,5% do grupo controle. Contudo, os valores de p não permaneceram significativos após correção.Discussão:Apesar de termos observado um aumento na tendência de os pacientes com CD terem o alelo HLA-B*18, os resultados não foram estatisticamente significativos após correção. Esse alelo foi maior em pacientes de etnia italiana e/ou espanhola, locais com frequências superiores a 18% e 14%, respectivamente. São necessárias investigações adicionais com uma coorte maior de pacientes com CD para confirmar o possível papel do HLA nessa doença.

Purpose: To investigate the predictors of intolerance to beta-blockers treatment and the 6-month mortality in hospitalized patients with acute coronary syndrome (ACS).Methods: This was a single-center, prospective, and longitudinal study including 370 consecutive ACS patients in Killip class I or II. BBs were prescribed according to international guidelines and withdrawn if intolerance occurred. The study was approved by the institutional ethics committee of our university. Statistics: the clinical parameters evaluated at admission, and the related intolerance to BBs and death at 6 months were analyzed using logistic regression (p<0.05) in PATIENTS.Results: BB intolerance was observed in 84 patients and was associated with no prior use of statins (OR: 2.16, 95%CI: 1.26-3.69, p= 0.005) and Killip class II (OR: 2.5, 95%CI: 1.30-4.75, p=0.004) in the model adjusted for age, sex, blood pressure, and renal function. There was no association with ST-segment alteration or left anterior descending coronary artery plaque. Intolerance to BB was associated with the greatest risk of death (OR: 4.5, 95%CI: 2.15-9.40, p<0.001).Conclusions: After ACS, intolerance to BBs in the first 48 h of admission was associated to non previous use of statin and Killip class II and had a high risk of death within 6 months.

We evaluated the frequency of different HLA-DRB1 alleles in Plasmodium vivax-infected individuals and in healthy blood donors from malaria endemic areas of Brazil. Low-resolution human leukocyte antigen-DRB1 genotyping was performed for 73 malaria patients and 29 healthy blood donors. The most frequent alleles in individuals from northern Brazil were human leukocyte antigen-DRB1*04, *08, *07 and *13. The frequency of human leukocyte antigen-DRB1*07 was higher in malaria-infected individuals than in the control group, which reinforces the theory that this allele plays an important role in susceptibility to malaria. This study offers new information about a potential susceptibility factor for P. vivax malaria in a Brazilian population that is naturally exposed to malaria.

In malocclusion studies, may happen not only dental discrepancies but even skeletal discrepancies. In Class III malocclusion can be observed underdeveloped maxilla, mandible protraction or both of them, and, in most of the times associated with a narrow maxilla that causes anterior or posterior crossbites, in one side or in two sides. The aim of this case report is to evaluate the facial profile and occlusal effects of interceptive orthodontics therapy. The treatment with upper arch expansion and maxilla protraction was done in an early age to be effective in the circummaxillary sutural system and to make the orthopedic effect easier. The facial mask used is positioned on two facial points and allows an anterior maxillary replacement. Patients’ compliance is important to reach treatment success, this because using the mask still in this growth and development phase is essential to make the facial and occlusal effects happen. It is important to mention that patients with Angle Class III malocclusion need to be followed till the end of their growth.
