Parâmetros De Avaliação Do Equilíbrio Sagital Cervical Na Escoliose Idiopática

There are no values defined as standard in the literature for the parameters of assessment of cervical sagittal balance in patients with idiopathic scoliosis. This study describes the sagittal cervical parameters in patients with idiopathic scoliosis. Methods: Study carried out in a tertiary public hospital in patients with adolescent idiopathic scoliosis, through the evaluation of panoramic radiographs in lateral view. The Cobb method was used to evaluate cervical lordosis from C2 to C7, distance from the center of gravity (COG) of the skull to C7, measurement of T1 slope, thoracic inlet angle (TIA), neck tilt, and plumb line from C7 to S1 (SVA C7-S1). A statistical analysis was performed, to demonstrate the relationship between the alignment of the thoracic spine in the sagittal plane and the cervical sagittal balance of patients with scoliosis. Results: Thirty-four patients were female (69.4%) and 15 male (30.6%). The mean values for COG-C7 were 0.71 mm (median 0.8 mm/standard deviation [SD]= 0.51 mm). For Cobb C2-C7, the mean was -11.7° (median -10°/SD= 20.4°). The mean slope of T1 was 23.5° (median 25°/SD= 9.5°). The mean cervical version was 58.8° (median 60°/DP= 15.4°). The mean TIA was 81.8° (median 85°/SD= 16.7°). The mean plumb line C7-S1 was -0.28 (-0.3/SD= 1.0). Conclusion: The analysis of the results showed that the mean values for the cervical lordosis are lower than the values described as normal in the literature, suggesting a loss of sagittal cervical balance in these patients.161384

Relação Entre Qualidade De Vida E Osteólise Em Torno De Parafusos Pediculares Lombares

To evaluate whether the presence of osteolysis around the pedicle screws affects the quality of life of patients who underwent posterolateral arthrodesis of the lumbosacral spine. Methods: A retrospective study of patients undergoing lumbar posterolateral or lumbosacral arthrodesis due to spinal degenerative disease. CT scans of the operated segments were performed at intervals of 45, 90, 180, and 360 postoperatively. In these tests, the presence of a peri-implant radiolucent halo was investigated, which was considered present when greater than 1mm in the coronal section. Concurrently with the completion of CT scans, the participants completed the questionnaire Oswestry Disability Index (ODI) to assess the degree of disability of the patients. Results: A total of 38 patients were evaluated, and 14 (36.84%) of them showed some degree of osteolysis around at least one pedicle screw at the end of follow-up. Of the 242 analyzed screws, 27 (11.15%) had osteolysis in the CT coronal section, with the majority of these occurrences located at the most distal level segment of the arthrodesis. There was no correlation between the presence of the osteolysis to the quality of life of patients. The quality of life has significantly improved when comparing the preoperative results with the postoperative results at different times of application of ODI. This improvement in ODI maintains linearity over time. Conclusion: There is no correlation between the presence of peri-implant osteolysis to the quality of life of patients undergoing lumbar or posterolateral lumbosacral arthrodesis in the follow-up period up to 360 days. The quality of life in postoperative has significantly improvement when compared to the preoperative period.15429029

Root canal retreatment: a retrospective investigation using regression and data mining methods for the prediction of technical quality and periapical healing

Objectives: This study aimed to investigate patterns and risk factors related to the feasibility of achieving technical quality and periapical healing in root canal non-surgical retreatment, using regression and data mining methods. Methodology: This retrospective observational study included 321 consecutive patients presenting for root canal retreatment. Patients were treated by graduate students, following standard protocols. Data on medical history, diagnosis, treatment, and follow-up visits variables were collected from physical records and periapical radiographs and transferred to an electronic chart database. Basic statistics were tabulated, and univariate and multivariate analytical methods were used to identify risk factors for technical quality and periapical healing. Decision trees were generated to predict technical quality and periapical healing patterns using the J48 algorithm in the Weka software. Results: Technical outcome was satisfactory in 65.20%, and we observed periapical healing in 80.50% of the cases. Several factors were related to technical quality, including severity of root curvature and altered root canal morphology (p<0.05). Follow-up periods had a mean of 4.05 years. Periapical lesion area, tooth type, and apical resorption proved to be significantly associated with retreatment failure (p<0.05). Data mining analysis suggested that apical root resorption might prevent satisfactory technical outcomes even in teeth with straight root canals. Also, large periapical lesions and poor root filling quality in primary endodontic treatment might be related to healing failure. Conclusion: Frequent patterns and factors affecting technical outcomes of endodontic retreatment included root canal morphological features and its alterations resulting from primary endodontic treatment. Healing outcomes were mainly associated with the extent of apical periodontitis pathological damages in dental and periapical tissues. To determine treatment predictability, we suggest patterns including clinical and radiographic features of apical periodontitis and technical quality of primary endodontic treatment

Tecnologias digitais na educação superior: reflexões acerca da disciplina de cálculo diferencial e integral i / digitals technologies in higher education: reflections about the differential and integral calculation discipline i

Com o avanço tecnológico, a utilização das Tecnologias Digitais da Informação e Comunicação (TDIC’s) tornou-se uma importante ferramenta para potencializar a aprendizagem em sala de aula, se usada corretamente. Deste modo, este artigo teve por objetivo analisar as pesquisas que utilizaram as TDIC’s efetivamente em sala de aula, como recurso didático, e não somente como fruto de pesquisa e/ou sugestão de utilização nos eventos Congresso Internacional de Educação Matemática (CIEM), Encontro Nacional de Educação Matemática (ENEM) e Encontro Mineiro de Educação Matemática (EMEM) no período 2008-2018.A metodologia utilizada foi de cunho qualitativo, com objetivo exploratório e tendo o estado da arte como procedimento técnico. O corpus analítico-investigativo final do trabalho, a partir da seleção nos anais dos respectivos eventos, consistiu em quatro produções, pautados sob o eixo temático “Tecnologia”. A técnica de análise dos dados utilizada foi a análise de conteúdo. Revelou-se aqui quais temáticas que recorreram a utilização das TDIC’s e quais são as TDIC’s utilizadas, bem como a escassez das produções acerca desta temática investigativa. Como principais achados da pesquisa, observou-se a falta de produções científicas que abordem as TDIC’s em conteúdos de Cálculo Diferencial e Integral I como ferramenta didático-pedagógica acompanhadas de resultados efetivos do potencial que elas podem melhorar o processo de ensino-aprendizagem

Reactional changes in short-term levonorgestrel-releasing intrauterine system (lng-ius) use

Objective: To evaluate endocervical and vaginal environment changes in women using a levonorgestrel-releasing intrauterine system (LNG-IUS). Methods: A quasi-experimental study included sixty women who had an LNG-IUS inserted in the Family Planning Clinic of UNICAMP between April and November of 2016. Women in reproductive age, non-pregnant, without the use of antibiotics and contraceptives seeking for LNG-IUS insertion were selected for this study. All women were evaluated with regard to vaginal and endocervical pH, vaginal and endocervical Gram-stained bacterioscopy, and Pap-smear before and two months after LNG-IUS insertion. Clinical aspects such as cervical mucus, vaginal discharge, and cervical ectopy were also observed. Results: After LNG-IUS insertion, there was an increase in the following parameters: endocervical pH>4.5 (p=0.02), endocervical neutrophil amount (p<0.0001), vaginal cytolysis (p=0.04). There was a decrease in vaginal discharge (p=0.01). No statistically significant changes were found in vaginal pH, neutrophils amount in the vaginal mucosa, vaginal discharge appearance, vaginal candidiasis, bacterial vaginosis, vaginal coccobacillary microbiota, cervical mucus appearance, or cervical ectopy size. Conclusions: Short-term LNG-IUS use did not increase vulvovaginal candidiasis or bacterial vaginosis, and led to diminished vaginal discharge. Notwithstanding, this device promoted reactional changes in the vaginal and endocervical environment, without modification on cervical ectopy size.65685786

Influência da heterogeneidade da serapilheira sobre as formigas que nidificam em galhos mortos em floresta nativa e plantio de eucalipto

This study investigated the twig-nesting ants of native forest and eucalyptus plantations in southeast of Brazil. The diversity of twig-nesting ants was greater on native forest than on eucalyptus plantations. Native forest had a greater diversity of twig types, mainly of those used by ants. Overall ant richness was 12 species in native forest and 4 species in eucalyptus plantations. The characteristics of litter and microclimatic conditions may be responsible for the different ant fauna found on both vegetation types. Key words: Atlantic Forest, Eucalyptus citriodora, diversidade, Formicidae.Este estudo investigou a fauna de formigas que nidifica em pequenos galhos da serapilheira em floresta nativa e em plantio de eucaliptos em área de Mata Atlântica no sudeste do Brasil. A densidade de galhos colonizados e a riqueza de espécies de formigas foram maiores em floresta nativa do que no eucaliptal, possivelmente porque a diversidade de galhos na serapilheira da floresta nativa foi maior, havendo uma maior abundância dos tipos mais usados pelas formigas. A riqueza total de formigas encontrada na mata nativa foi de 12 espécies, enquanto que apenas quatro espécies foram encontradas em plantio de eucaliptos. As características da serapilheira em conjunto com condições microclimáticas diferenciadas podem ser responsáveis pelo padrão de uso de galhos por formigas observado na área de estudo.
