Características cefalométricas de pacientes portadores de más oclusões Classe I e Classe II de Angle Cephalometric characteristics of patients with Angle Class I and Class II malocclusions

OBJETIVOS: o presente estudo comparou algumas medidas cefalométricas relacionadas às características faciais em pacientes com má oclusão Classe I, Classe II 1ª divisão e Classe II 2ª divisão. METODOLOGIA: foram selecionadas 130 telerradiografias de pacientes leucodermas em fase inicial de tratamento ortodôntico, com idades entre 10 e 16 anos (média de 12,6 anos); e divididos em 3 grupos. As medidas cefalométricas utilizadas neste estudo foram: ANB, &#305;-SN, IMPA, AML, Ls-&#305;, Li-&#299; e EI. A análise de variância e o teste de Tukey foram realizados nas medidas ANB, IMPA, AML, &#305;-SN e Li-&#299;. Para as demais variáveis (EI e Ls-&#305;) foi utilizado o teste de Kruskal Wallis e Dunn. RESULTADOS: os resultados mostraram que as medidas Ls-&#305; e EI tiveram diferença estatisticamente significativa entre os grupos I e II-1 e entre os grupos II-1 e II-2 (p < 0,05). As medidas ANB e IMPA tiveram diferença estatisticamente significativa entre os grupos I e II-1 e entre os grupos I e II-2 (p < 0,05). A medida &#305;-SN teve diferença estatisticamente significativa entre os 3 grupos (p < 0,05). CONCLUSÕES: pode-se concluir que a medida &#305;-SN mostrou ser uma medida capaz de diferenciar os 3 tipos de más oclusões e a medida IMPA demonstrou que o comportamento axial dos incisivos inferiores em sua base óssea é bastante variável. A má oclusão Classe II 1ª divisão apresenta características faciais que a diferenciam da Classe II 2ª divisão e Classe I, quanto às medidas AML, Ls-&#305; e EI. As más oclusões Classe II 1ª divisão, Classe II 2ª divisão e Classe I não apresentaram características faciais diferentes para a medida Li-&#299;.<br>AIM: The present study compared some cephalometric measurements related to facial characteristics in patients having Class I, Class II division 1, and Class II division 2 malocclusions. METHODS: One hundred and thirty teleradiographs of Caucasian patients aged 10-16 years (mean age of 12.6 years) under initial orthodontic treatment were selected for study and divided into 3 groups. The cephalometric measurements used in the present study were the following: ANB, &#305;-SN, IMPA, AML, Ls-&#305;, Li-&#299;, and EI. Variance analysis and Tukey's test were carried out for ANB, IMPA, AML, &#305;-SN, and Li-&#299; measurements, whereas Kruskal-Wallis and Dunn's tests were used for EI and Ls-&#305;. RESULTS: Statistically significant differences were found for EI and Ls-&#305; measurements when Group II-1 was compared to Group I and Group II-2 (p < 0.05). ANB and IMPA measurements also had statistically significant differences when Group I was compared to Group II-1 and Group II-2 (p < 0.05). The measurement &#305;-SN had statistically significant differences between the 3 groups (p < 0.05). CONCLUSIONS: One can conclude that the measurement &#305;-SN was found to be capable of differentiating the 3 types of malocclusions, whereas measurement IMPA showed that lower incisors have a variable axial behavior regarding their osseous bases. Based on the AML, EI and Ls-&#305; measurements, Class II division 1 malocclusion was found to have facial characteristics which differentiate it from Class II division 2 and Class I malocclusions. Class II division 1, Class II division 2, and Class I malocclusions did not show different facial characteristics regarding the measurement Li-&#299;

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

Background: Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods: The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results: A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion: Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
