La dentición humana presenta una notable estabilidad morfológica, mediada por un fuerte control poligénico y una baja influencia de factores ambientales. Estas características vuelven a los rasgos dentales discontinuos muy útiles para evaluar vinculaciones biológicas entre grupos humanos y para la identificación de individuos en contextos forenses. Dens evaginatus es un rasgo dental discreto poco usual que se presenta en forma de tubérculo en la cara lingual y labial de los dientes anteriores y en la cara oclusal de los dientes posteriores. En este trabajo se presenta el primer caso bioarqueológico de dens evaginatus descripto en Argentina para individuos con dentición permanente, en los segundos premolares inferiores de un cráneo procedente de la provincia de Mendoza. Se examina el rasgo en función de los distintos criterios clasificatorios existentes, se evalúa la presencia de desgaste dental y de patologías orales asociados al mismo y se analizan las implicancias de este en la caracterización biológica del individuo estudiado.

Well-conducted randomized controlled trials (RCTs) represent the highest level of evidence when the research question relates to the effect of therapeutic or preventive interventions. However, the degree of control over bias between RCTs presents great variability between studies. For this reason, with the increasing interest in and production of systematic reviews and meta-analyses, it has been necessary to develop methodology supported by empirical evidence, so as to encourage and enhance the production of valid RCTs with low risk of bias. The aim here was to conduct a methodological analysis within the field of dentistry, regarding the risk of bias in open-access RCTs available in the Lilacs (Literatura Latino-Americana e do Caribe em Ciências da Saúde) database. This was a methodology study conducted at Universidade Federal de São Paulo (Unifesp) that assessed the risk of bias in RCTs, using the following dimensions: allocation sequence generation, allocation concealment, blinding, and data on incomplete outcomes. Out of the 4,503 articles classified, only 10 studies (0.22%) were considered to be true RCTs and, of these, only a single study was classified as presenting low risk of bias. The items that the authors of these RCTs most frequently controlled for were blinding and data on incomplete outcomes. The effective presence of bias seriously weakened the reliability of the results from the dental studies evaluated, such that they would be of little use for clinicians and administrators as support for decision-making processes.
Resumo Os aneurismas de artéria poplítea correspondem a 70% dos aneurismas periféricos e o tratamento é cirúrgico, com controvérsias sobre os resultados da via endovascular. Este estudo objetivou realizar uma revisão da literatura sobre a comparação entre cirurgia aberta e endovascular no tratamento dos aneurismas da artéria poplítea. A pesquisa foi realizada utilizando os termos apropriados nos portais de periódicos LILACS e MEDLINE, com a seleção de 15 artigos. Um total de 5.166 procedimentos cirúrgicos foram comparados, sendo 3.930 cirurgias abertas e 1.236 cirurgias endovasculares. A cirurgia aberta com bypass venoso continua sendo o padrão-ouro. A cirurgia endovascular apresenta menor tempo de internação e é uma opção viável em pacientes eletivos, com baixa expectativa de vida, alto risco cirúrgico, comorbidades e mais idosos, desde que tenham anatomia favorável para o procedimento. Contudo, são necessários estudos de longo prazo para estabelecer os reais benefícios e indicações das duas técnicas, como o ensaio clínico randomizado controlado.
Misoprostol is reported to prevent non-steroidal anti-inflammatory drug (NSAID)-associated gastroduodenal complications. There is, however, limited information regarding the efficacy of DA-9601 in this context. We performed a comparative study on the relative efficacy of DA-9601 and misoprostol for prevention of NSAID-associated complications. In this multicenter, double-blinded, active-controlled, stratified randomized, parallel group, non-inferiority trial, 520 patients who were to be treated with an NSAID (aceclofenac, 100 mg, twice daily) over a 4-week period were randomly assigned to groups for coincidental treatment with DA-9601 (60 mg, thrice daily) (236 patients for full analysis) or misoprostol (200 μg, thrice daily) (242 patients for full analysis). [corrected]. The primary endpoint was the gastric protection rate, and secondary endpoints were the duodenal protection rate and ulcer incidence rate. Endpoints were assessed by endoscopy after the 4-week treatment period. Drug-related adverse effects, including gastrointestinal (GI) symptoms, were also compared. At week 4, the gastric protection rates with DA-9601 and misoprostol were 81.4 % (192/236) and 89.3 % (216/242), respectively. The difference between the groups was -14.2 %, indicating non-inferiority of DA-9601 to misoprostol. Adverse event rates were not different between the two groups; however, the total scores for GI symptoms before and after administration were significantly lower in the DA-9601 group than in the misoprostol group (-0.2 2.8 vs 1.2 3.2; p
To describe orofacial muscle function in patients with severe asthma. This was a descriptive study comparing patients with severe controlled asthma (SCA) and severe uncontrolled asthma (SUA). We selected 160 patients, who completed a sociodemographic questionnaire and the 6-item Asthma Control Questionnaire (ACQ-6), as well as undergoing evaluation of orofacial muscle function. Of the 160 patients evaluated, 126 (78.8%) and 34 (21.2%) presented with SCA and SUA, respectively, as defined by the Global Initiative for Asthma criteria. Regardless of the level of asthma control, the most frequent changes found after evaluation of muscle function were difficulty in chewing, oronasal breathing pattern, below-average or poor dental arch condition, and difficulty in swallowing. When the sample was stratified by FEV1 (% of predicted), was significantly higher proportions of SUA group patients, compared with SCA group patients, showed habitual open-mouth chewing (24.8% vs. 7.7%; p
