Calvarial Autogenous Bone Graft for Maxillary Ridge and Sinus Reconstruction for Rehabilitation With Dental Implants

Autogenous bone grafting is the gold-standard technique for bone augmentation procedures prior to implant placement. If the amount of available intraoral donor bone is insufficient, it is necessary to harvest bone graft from extraoral sites, such as calvaria. Although this technique is well established, only a few case reports show the histological analysis of the grafted bone at the moment of implant placement. This article reports the case of a 48-year-old female patient with a critical atrophic maxillary ridge reconstructed using autogenous calvarial bone graft prior to implant placement, with clinical and histological evaluation. Bone was collected under general anesthesia from the parietal bone. The outer cortical originated the bone blocks, and the medullar bone layer between was collected to be used in the sinus augmentation procedure, together with 5 of the bone blocks triturated. Six months after bone augmentation, 8 implants were placed in the grafted area and 2 biopsies were retrieved (anterior and the posterior regions), allowing the visualization of the bone-remodeling process in the grafted areas. The patient had a stable recovery. Our results showed that although necrotic bone could still be seen in the outer layer of the grafted area, the interface between this necrotic bone and the already remodeled bone was consistent with biocompatibility. Two-year radiographic evaluation showed success of the grafts and the implants in supporting an esthetic and functionally stable prosthesis. Summarizing, calvarial bone grafts are a viable alternative for the attainment of adequate bone volume prior to implant placement.

Villa Aurore, de J.-M Gustave Le Clézio: duplicações literárias

Le conte “Villa Aurore” montre bien la mobilité et la duplicité qui caractérisent l’oeuvre de Le Clézio: en même temps que le titre de cet ouvrage, La ronde et autres faits divers, annonce la représentation de la réalité à partir des faits divers, la présence du mythe donne au récit un fort potentiel poétique, qui peut être constaté surtout dans le lyrisme du langage et dans les procédés poétiques que l’auteur utilise dans la création de ses récits. Tel que dans d’autres textes de La ronde et autres faits divers, le conte “Villa Aurore” montre la force d’un récit réaliste, attaché à la banalité quotidienne, mais qui se tourne vers le mythe, en configurant une structure circulaire, dont relève le doublement des catégories narratives du temps, de l'espace et du narrateur. Ainsi, ce travail a l’objectif de montrer comment les représentations du narrateur, du temps et de l’espace, doublées et opposées, contribuent-elles à déterminer cette structure et aussi comment semblent-elles converger pour l’expression du désir de l’évocation d’une quête sur les origines dans le corpus étudié

Apectos do fantástico e tradução de um conto de Mracel Aymé

Le corpus de ce travail est constitué par le conte ―Le passe-muraille‖ de Marcel Aymé. À travers la traduction du conte, notre objectif est d’abord de commenter les difficutés trouvées et les solutions données tout du long du processus. En plus, le conte est analisé sous la perspective de la théorie du fantastique, pour montrer que cet ouvrage conserve des caractéristiques du récit fantastique traditionnel du XIX siècle, mais en même temps ces caractériques sont presentées d’une façon tout à fait différente

Reconhecimento de voz para aplicações em automação implementado em FPGA

In many movies of scientific fiction, machines were capable of speaking with humans. However mankind is still far away of getting those types of machines, like the famous character C3PO of Star Wars. During the last six decades the automatic speech recognition systems have been the target of many studies. Throughout these years many technics were developed to be used in applications of both software and hardware. There are many types of automatic speech recognition system, among which the one used in this work were the isolated word and independent of the speaker system, using Hidden Markov Models as the recognition system. The goals of this work is to project and synthesize the first two steps of the speech recognition system, the steps are: the speech signal acquisition and the pre-processing of the signal. Both steps were developed in a reprogrammable component named FPGA, using the VHDL hardware description language, owing to the high performance of this component and the flexibility of the language. In this work it is presented all the theory of digital signal processing, as Fast Fourier Transforms and digital filters and also all the theory of speech recognition using Hidden Markov Models and LPC processor. It is also presented all the results obtained for each one of the blocks synthesized e verified in hardware

Ação de topiramato sobre o desenvolvimento larval de Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae)

A Entomologia Forense é um ramo de investigação científica que aplica o estudo de insetos e outros artrópodes a procedimentos legais e está se desenvolvendo e chamando bastante atenção nos últimos anos. Diversos estudos vêm sendo realizados nesta área para que os profissionais responsáveis possuam o maior número de informações possível sobre os insetos utilizados para estes fins, permitindo-lhes assim fazer melhores análises nos casos litigiosos envolvendo a descoberta da causa até a estimativa de tempo do intervalo pós-morte (I.P.M.) em um cadáver humano. Dentro deste ramo de estudo, a ordem Diptera apresenta certo destaque por apresentar diversos insetos com hábitos necrófagos, como por exemplo a família Calliphoridae, que se destaca pela grande distribuição e número de registros da presença de seus representantes nos tecidos de corpos animais no início da decomposição. A espécie Chrysomya megacephala (Fabricius), pertencente a esta família, tendo sido introduzida acidentalmente aqui no Brasil alguns anos atrás, possui uma importância médico-sanitária como veiculadora de patógenos, eventual causadora de miíases e, pelo fato de colocar seus ovos sobre tecidos de animais em decomposição, é uma importante espécie utilizada em estudos forenses. Baseando-se em trabalhos já realizados, sabe-se que a presença de determinadas substâncias químicas no substrato alimentar das larvas destas moscas pode alterar seu desenvolvimento, e sabendo quais seriam as mudanças provocadas por uma dessas substâncias, a análise do cadáver se tornaria mais completa e confiável durante a estimativa do I.P.M. A área responsável pelo estudo da interação entre substâncias químicas e os seus efeitos nos insetos é chamada de Entomotoxicologia, que também permite detectar traços de drogas lícitas ou não no trato digestivo de insetos necrófagos...

Amphibians of grasslands in the state of Paraná, southern Brazil (Campos Sulinos)

Amphibian conservation depends on knowledge about species composition and distribution. This emphasizes the need for inventories, especially in poorly sampled areas. This is the case of Southern grasslands (Campos Sulinos) associated with Araucaria forest in the state of Paraná, southern Brazil. We sampled amphibians in 105 environments from 2004 to 2013 using transect sampling, active search and surveys at breeding sites. We found 61 anuran species and two caecilians. This is the first comprehensive list of amphibian species inhabiting grasslands in Paraná. This landscape deserves high conservation priority before these natural grasslands vanish.

Osteomielitis crónica con periostitis proliferativa

Chronic osteomyelitis with proliferative periostitis is a kind of osteomyelitis that is characterized by a great periosteal reaction resulting of low grade stimulation, usually a caries lesion associated a periapical pathology. It affects especially children and young adults, with the mandible as the most common site, usually in the inferior aspect. Clinically presents as a painless hard swelling intra and/or extra-oral. Radiographic aspects include bone layers new formed, parallel to each other and to the underlying cortical surface, giving the characteristic appearance of "onion skin". Treatment includes elimination of the cause, with or without antibiotics, being restored the facial symmetry of patient. The present article is a clinical case report of chronic osteomyelitis with proliferative periostitis affecting a female 11 year old patient, caused by a caries lesion in the left permanent first molar, that was submissed to a exodontia and the facial symmetry of the patient was restored with management.

Nasopalatine duct cyst: a case report within 3 years follow-up

The nasopalatine duct cyst (NPDC) is considered to be the most common non-odontogenic cyst in oral cavity. These cysts are usually asymptomatic; however they can result in swelling, pain and drainage. The radiological analysis can reveal a round, oval or heart shaped well-demarcated image, which can be confounding with inflammatory lesions. The aim of this paper is report a clinical case of NPDC in a patient of 33 years old, occurring near a periapical inflammatory lesion. During clinical examination, it was not possible to detect swelling of the anterior palate and patient didn´t complain painful symptoms. Surgical treatment, enucleation, was performed under local anesthesia and there was no post operative complications. Histological results showed the presence of a cuboidal and respiratory epithelium associated with vessels, nerves and inflammatory cells. The patient’s 3 years follow-up was uneventful with subsequent bone regeneration and no sign of the lesion recurrence.

Implantes dentais em pacientes com diabetes mellitus

Dental implants represent a great improvement in Dentistry in respect to rehabilitation of edentulous ridges due to the functional and aesthetic reestablishment with long-term predictability and success. However, the effectiveness of this treatment relies on successful osseointegration during the healing period. In this way, the applicability of dental implants in patients with diabetes mellitus (DM) remains controversial, by the fact that the hyperglycemic status presents a negative effect on the osseointegration. It is not clear yet if the therapy with dental implants is an absolute contraindication to these patients. For this reason, the aim of the present study is to review the literature about the treatment with dental implants in patients with diabetes and to propose a protocol to perform dental implants in patients with diabetes. Diabetes has been considered a relative contraindication to dental implants, as the patients with adequate metabolic control can be treated with this kind of therapy, because inadequate metabolic control can lead to the failure of the treatment. Besides, there are risk factors for the diabetic implant patient that may decrease the success rates of dental implants therapy. In this way, the dentist should understand all the relevant implications before considering the indication of dental implants to patients with diabetes. It is important to have more controlled studies to evaluate the effects of diabetes on the implant-tissue interface and further investigations are necessary in order to elucidate the role of insulin and molecular mechanisms that might interfere on the osseointegration in patients with diabetes.
