Patient attended a dental clinic because she wanted to replace the missing tooth with an implant. She reported having lost the temporary tooth for one year. The initial Cone-beam Computerised Tomography image showed an edentulous area in the #13 zone, and the presence of a fragment of the deciduous tooth. The small root fragment was removed and an implant 4.0 × 13 mm amplified was installed. Patient presented acute pain and inflammation at the implant site 20 d after the surgery when the implant was originally installed; the first periapical surgery was carried out. Four months after the first periapical surgery, in periapical x-ray a radiolucent lesion was observed surrounding the apical region of the implant with a dry sound under percussion. The second periapical surgery was carried out. Five months after the second periapical surgery, the presence of a fistula was observed clinically, while in X-ray a radiolucent lesion was observed in the apex of the implant. Implant-plasty was carried out, removing approximately 5 mm of the apical portion of the implant. This treatment was successful after 27 months' monitoring. © 2018, Scientific Publishers of India.

Production of doubly charged vector bilepton pairs at γγ\gamma \gamma colliders

The production of pairs of doubly charged vector bileptons is studied at future $\gamma \gamma$ colliders. The unpolarized cross--section for the $\gamma \gamma \to Y^{--}Y^{++}$ subprocess is analytically calculated and convoluted to predict the number of events in the complete $e^+e^-\to \gamma \gamma \to Y^{--}Y^{++}$ process. The gauge or non--gauge character of the vector bilepton $Y^{\pm \pm}$ is discussed. It is found that as a consequence of its spectacular signature, as it decays dominantly into two identical charged leptons, and also due to its charge contents, which significantly enhance the cross--section, the detection of this class of particles with mass in the sub--TeV region can be at the reach of these colliders. The model--independent nature of our results is stressed.Comment: 9 pages, 7 figures, submitted to physical review

Intratumoral hemorrhage in tuberous sclerosis: case report

The authors report the case of 19 year-old patient with features of tuberous sclerosis that developed a massive hemorrhage in a subependymal giant-cell astrocytoma causing sudden death. Aspects of the pathophysiological bleeding are discussed.Os autores relatam o caso de uma paciente de 19 anos de idade, com quadro característico de esclerose tuberosa, que evoluiu com hemorragia maciça em astrocitoma subependimário de células gigantes e óbito súbito. Aspectos da fisiopatologia do sangramento são discutidos.43543

Impactos da pandemia Covid-19 em empresas de grande porte: avaliação das mudanças na infraestrutura de tecnologia para o teletrabalho sob as óticas das teorias das capacidades dinâmicas e estrutura adaptativa

With the emergence of the new Covid-19 disease in Brazil in the beginning of 2020, many companies had to reduce their activities or even paralyze them completely, another part of these companies had an additional demand compared to the daily history of operation. The objective of this article is to understand and analyze the main difficulties in the IT field of three large companies to adapt their ICT infrastructure to the new scenario under the theoretical lenses of the Theory of Dynamic Capacities and Theory of Adaptive Structuring. The methodology of this research project proposes the study of multiple cases with a longitudinal perspective and the Dynamic Capabilities Research Model and the Technology Appropriation Model with an exploratory approach, through a case study. As a result, the two models prove that companies A, B and C were able to meet the new demands, adapting their ICT infrastructures to the new scenario caused by the Covid-19 pandemic, forcing employees to adopt the new form of work.Con el surgimiento de la nueva enfermedad Covid-19 en Brasil a principios de 2020, muchas empresas tuvieron que reducir sus actividades o incluso paralizarlas totalmente, otra parte de estas empresas tuvieron una demanda adicional en comparación con el cotidiano histórico de operación.

La metodología de este proyecto de investigación propone el estudio de casos múltiples con perspectiva longitudinal y los frameworks Modelo de Investigación de Capacidades Dinámicas y el Modelo de Apropiación de Tecnología con abordaje de naturaleza exploratoria, por medio de estudio de caso. Como resultado, los dos modelos demuestran que las empresas A, B y C fueron capaces de soportar las nuevas demandas, adaptando sus infraestructuras de Tics al nuevo escenario causado por la pandemia de Covid-19, obligando a los empleados a adoptar la nueva forma de trabajo.Com o surgimento da nova doença Covid-19 no Brasil no início de 2020, muitas empresas tiveram que que reduzir suas atividades ou até mesmo paralisá-las totalmente, outra parte dessas empresas tiveram uma demanda adicional se comparado com o cotidiano histórico de operação.
