Root ZX Electronic Foramen Locator: An Ex Vivo Study of Its Three Models’ Precision and Reproducibility

Although Root ZX is considered the gold standard electronic foramen locator (EFL), two variations of this device were launched, however without different operating mechanisms. This investigation aims to evaluate the precision of Root ZX (RZX), Root ZX II (RII), and Root ZX Mini (RM) EFLs. After access cavity preparation, 32 mandibular single rooted human premolars had their real length measured with the aid of a #15 K-type manual file under magnification (25x). Electronic measurements were performed by the devices in an alternate order until the apical foramen was reached (0.0). Each measurement was performed with adjusted file to the real length of the teeth and verified with a digital caliper. The accuracy of the EFLs was 68.8% (RZX), 65.8% (RII), and 68.8% (RM), considering ±0.5 mm as a margin of tolerance. The mean errors of the devices were 0.37±0.25 mm (RZX), 0.41±0.34 mm (RII), and 0.32±0.28 mm (RM). ANOVA and Tukey test were applied to analyze the obtained data, which showed that there were no statistically significant differences among the locators (P>.05). It can be concluded that the three tested devices demonstrated precise measurements of the real length of the canal without performance differences among them

Enfrentamento à pandemia: conhecimento acessível à comunidade / Coping with the pandemic: Knowledge accessible to the community

A pandemia pela COVID-19 altera a saúde global e coloca em risco a comunidade e o grupo de pessoas com deficiência visual e surdas. Docentes e alunos da Universidade Federal de Minas Gerais decidiram ofertar curso via e-mail e via página eletrônica para disseminar conhecimento sobre medidas preventivas e combate às fake News. A divulgação ocorreu dentro da comunidade universitária e em grupos comunitários. O objetivo deste estudo foi avaliar duas metodologias (por e-mail e pela página eletrônica) do curso, com avaliação do perfil dos participantes, da adesão e do desempenho. O curso contou com 1.841 inscritos. O grupo de participantes via e-mail apresentou em relação aos demais:  idade superior (p<0,001); maior número de deficientes (p=0,008) e de mulheres (p<0,001); maior escolaridade (p<0,001). Constatou-se associação entre a metodologia do curso e ter ou não recebido o auxílio financeiro emergencial (p=0,001) devido à pandemia e possuir filhos (p<0,001). Ocorreu progressão no conhecimento em ambos os grupos. A persistência até o final do curso foi maior no sexo masculino com correlação positiva (p=0,03; força de associação de 5,1%). Aqueles que não finalizaram o curso apresentaram média de idade superior (37,5 anos) aos que finalizaram (35,6 anos), com p=0,04. Apesar da baixa adesão geral, o curso contribuiu de forma acessível para disseminação do conhecimento científico sobre a COVID-19

PREVALÊNCIA DE ENCURTAMENTO MUSCULAR EM PROFISSIONAIS DA TECNOLOGIA DA INFORMAÇÃO

Introdução: A área da Tecnologia da Informação (TI) assume um papel impactante nas organizações onde estão inseridas para que estas possam competir e se sobressair aos concorrentes. Os indivíduos que atuam nessa área permanecem longos períodos com a maior parte do corpo, principalmente coluna vertebral e membros inferiores, em posturas inertes, o que de acordo com a literatura atual, afetará as condições de saúde do trabalhador. O trabalho estático, sobretudo sentado, gera tensão muscular desfavorecendo o aporte sanguíneo com consequente prejuízo do bombeamento rítmico dos músculos esqueléticos, o que, pela prática constante e repetitiva, causará encurtamento muscular, além de excessiva carga biomecânica sobre os discos intervertebrais e fadiga. Objetivo: Verificar a prevalência de encurtamento muscular em profissionais da TI. Metodologia: A pesquisa foi realizada no período de março a junho de 2017. Os dados foram coletados a partir de Testes Específicos a saber: Teste de Thomas; Teste de Ober; Teste de Elevação da Perna Estendida; Teste do Piriforme; Teste do Peitoral Maior e Menor; Teste do III Dedo ao Solo; Teste de Schober e Teste de Stibor. Resultados: Foram avaliados 15 profissionais do setor de TI do Centro Universitário Católica de Quixadá, sendo 13 homens e 2 mulheres, com idade entre 20 e 46 anos, que trabalhavam em média 8,5 horas por dia. Os principais achados incluem alta prevalência de contraturas em iliopsoas, sempre bilateral; em piriforme, predominantemente à direita e ainda de importantes encurtamentos da cadeia posterior. Vale ressaltar ainda que 87% dos avaliados apresentaram restrição na mobilidade articular da coluna vertebral. Conclusão: A atividade laboral exercida na postura sentada predominantemente estática, pode ser considerada um fator determinante para o aumento da prevalência de encurtamentos musculares e restrições de mobilidade na coluna vertebral. Destaca-se então, a importância da atenção fisioterapêutica para profissionais que adotam essa postura por longos períodos

Mental disorders in children and adolescents with lower urinary tract dysfunction

Abstract Lower urinary tract dysfunction (LUTD) affects about 2-25% of the pediatric population and is associated with the presence of emotional and behavioral disorders. The purpose of this literature review was to identify studies focusing on mental disorders in children and adolescents with LUTD. The prevalence of these disorders is high - ranging from about 20 to 40% - in children with symptoms of LUTD and comorbidities. The presence of emotional and behavioral symptoms impact in the treatment of the dysfunction, self-esteem of patients and caregivers. Despite the association between mental/behavioral disorders and LUTD be well documented in the literature, the investigation of psychiatric symptoms in clinical practice is still not common and should be stimulated

Higher Concentration of Taenia Antigens in the CSF is Related to Slight Ventricle Enlargement and Periventricular Neuronal Decrease in Young Rats

Purpose Experimental models might help understand the pathophysiology of neurocysticercosis-associated hydrocephalus. The present study aimed to compare the extent of hydrocephalus and tissue damage in rats with subarachnoid inoculation of different concentrations of Taenia crassiceps cyst proteins. Methods Sixty young rats were divided into two groups: low- and high-concentration groups. The animals in the low concentration group received 0.02 ml of 2.4 mg/ml T. crassiceps cyst proteins while those in the high concentration group received 0.02 ml of 11.6 mg/ml T. crassiceps cyst proteins. The animals underwent magnetic resonance imaging at 1, 3, and 6 months postinoculation to assess the ventricle volume. Morphological assessment was performed at the end of the observation period. Results Repeated measures of ventricle volumes at 1, 3, and 6 months showed progressive enlargement of the ventricles. At 1 and 3 months, we observed no differences in ventricle volumes between the 2 groups. However, at 6 months, the ventricles were larger in the high concentration group (median = 3.86 mm3, range: 2.37–12.68) compared with the low concentration group (median = 2.00 mm3, range: 0.37–11.57), p = 0.003. The morphological assessment revealed a few inflammatory features in both groups. However, the density of oligodendrocytes and neurons within the periventricular region was lower in the high concentration group (5.18 versus 9.72 for oligodendrocytes and 15.69 versus 21.00 for neurons; p < 0.001 for both). Conclusion Our results suggest that, in rats, a higher concentration of T. crassiceps cyst proteins in the subarachnoid space could induce ventricle enlargement and reduce the number of neurons within the periventricular area

Translation, cross-cultural adaptation and validation of the Short Screening Instrument for Psychological Problems in Enuresis for use in Brazil (SSIPPE-Br)

Objective: Enuresis is associated with attentional and emotional comorbidities in 20 to 30 % of cases. The Short Screening Instrument for Psychological Problems in Enuresis (SSIPPE) is a questionnaire that allows the initial screening of these comorbidities. This study aimed to translate, culturally adapt, and validate the SSIPPE for Brazilian children and adolescents (SSIPPE-Br). Methods: Six steps were performed for translation and cross-cultural adaptation: translation, synthesis of translations, back-translation, preparation of the pre-final version of the translated instrument, test of comprehensibility of the pre-final version of the tool, and elaboration of the instrument cross-culturally adapted for Brazil, named 13-itens version SSIPPE-Br. To validate the SSIPPE-Br, a cross-sectional study was carried out, in which the validated Brazilian version of the Child and Adolescent Behavior Inventory (CABI) was used. Results: Validation was performed on 127 children and adolescents with a mean age of 9.7 ± 2.8 years, 48 % male. The reliability was estimated using Cronbach's alpha, ranging from 0.86 to 0.89, indicating good internal consistency. The factorial analysis had a good agreement adjustment (KMO 0.755, Bartlett's test < 0.001) and explained 70.5 % of the data variability. In the reproducibility analysis, the Kappa coefficient ranged from 0.94 to 1, which can be considered almost perfect. A highly significant (p-value < 0.001) and direct correlation existed between the three SSIPPE-Br domains and all evaluated CABI domains. Conclusion: The SSIPPE-Br is a valid and reliable tool for emotional problems screening and ADHD symptoms in children and adolescents with enuresis whose first language is Brazilian Portuguese
