Oclusão em prótese sobre implante - parte II

In part I of this article, the factors related to the establishment of a favourable occlusion for the implant prosthodontics as well as its real importance in this kind of rehabilitation were showed up. However, it is known that the occlusal characteristics adopted in implant prosthodontics show specific patterns which must be different between each other in accordance to the type of prosthesis installed. The objective of the second part of this work is to present to the reader, by a literature review, those characteristics, justifying the reason because they must be associated to specific kind of prosthesis for favor the treatment established.

O brincar para conhecer o desenvolvimento de crianças com implante coclear

This research analyses the development of children presented with profound deafness and benefited by the cochlear implant, discovery of great significance in hearing health. The work is based, theoretically, on Winnicott, and methodologically, in anamnesis data and playing on a set of ludic scenes, systematically organized. Ten pre-school children with implants, selected by hospital and homogenization eligibility criteria participate in this study encompassing interviews with parents and playful observation sessions with the children, besides Lynn´s Dolls Structured Game. In the children, the results show immaturity, regression to earlier stages of their development, dependency and behavioral disorders, in particular, those related to language, interrelationship and anxiety. In the parents, family disorientation, partly overcome. The children and family participating are assisted by a multidisciplinary health team, at the hospital where they are attended.

Desempenho de crianças com deficiência auditiva e implante coclear em tarefas de seleção de e de nomeação de figuras

The aim of this study was to investigate the development of specific domains of Numerical Cognition (Number Sense – NS, Number Comprehension – NC, Number Production – NP, and Calculation – CA) in Brazilian children with Specific Learning Disorders. The study included 72 children (36 boys), from 9-to 10-years-old, enrolled in 4th and 5th years of elementary school of public schools at countryside of Sao Paulo State, Brazil. They were divided into three groups: control (CT, N = 42), Developmental Dyslexia (DL, N = 11) and Developmental Dyscalculia combined with dyslexia (DDc, N = 19). All participants had intellectual level within the normal range, however, children from the last two groups had Learning Disorders classified by School Achievement Test - TDE (Stein, 1994) and DDc children received necessarily classification as 'inferior' in Arithmetic Test of TDE. The children did not differ in NS. DL and DDc children showed slight deficits in NC. However, DDc children had moderate in NP and mild to moderate deficits in CA, which indicates a more generalized impairment in Numerical Cognition. Furthermore, DDc children showed discrepancy in Numerical Cognition performance when compared to the other groups. Thus, children with Learning Disorders showed different performances in Numerical Cognition, although both groups had preserved SN, DDc children showed higher deficits and discrepancy in relation DL and typically developing children.

Aprendizagem após via exclusão e formação de classes de equivalência em crianças com deficiência auditiva e implante coclear (aceito condicionalmente)

Studies on learning by exclusion have shown that participants tend to select a new object or a new figure when a new word is dictated, rejecting the objects and figures they already know or that were associated with other words. This study aimed at training conditional relations between dictated word-picture and between picture-printed word, by exclusion, and verify whether this training would be a condition for the emergence of relations between dictated word-printed word, printed word-figure, picture naming and reading. We also investigated whether responding to the words dictated with a female voice generalized to other frequencies such as male and child voices. Participants were five children between five and nine years old, with acute neurosensorial bilateral hearing impairment, users of cochlear implant Nucleus 24k®. They were exposed, individually, to tasks that consisted in selecting a comparison stimulus (either picture or printed word) related to the sample (either dictated word or picture). Words with lowest scores on a pre-test were used. The relations between dictated word-figure (AB) and figure-printed word (BC) were taught by exclusion. We assessed the emergence of the relations between dictated and printed words (AC), printed word and picture (CB), male and child voices generalization (A’C and A’’C), naming (BD) and reading (CD). All the children responded by exclusion and learned relations AB and BC, showing receptive vocabulary; AC and CB relations also were learned, consistent with class formation. Responding generalized to male and child voices, but data on naming were not systematic. Learning by exclusion was similar to that of children with typical hearing and these results describe some conditions that can improve receptive verbal repertoire.

Ecóico e nomeação de figuras em crianças com deficiência auditiva pré-lingual com implante coclear

The aim of this work was to verify the effect of teaching the echoic behavior over the pictures naming in four children between eight and nine years old with prelingual hearing impaired, users of cochlear implants. The design adopted was: (a) pre-training that taught the matching-to-sample task; (b) pre-tests that selected three words to teach; (c) teaching of auditory-visual conditional relations; (d) naming pos-test; (e) the teaching of echoic with orofacial clues and, (f) the second naming pos-test. In the pre-test all participants achieved smaller percentage of correct on naming (60%-80%) and echoic (20%-50%) when compared to percentages word recognition (86%-93%). All participants learned the auditory-visual relations. The improvement on naming test occurred after auditory training select based for two participants; for other two participants the improvement on naming test occurred just after the training of echoic. Analysis of data showed that the listening and speaking performances are independent in their establishment and require specific conditions of teaching; in the case of this study, even though the result is not generalized to all participants, the highest correspondence into point to point naming was obtained following the teaching of echoic.

Análise macroscópica e histológica do emprego da poliuretana derivada do óleo de mamona (Ricinus communis) aplicada na tíbia de cães em fase de crescimento

OBJETIVO: Estudar o efeito da poliuretana de mamona aplicada ao osso de cães em crescimento. MÉTODOS: Foram utilizados 12 cães subdivididos aleatoriamente em 3 grupos, os quais receberam o implante de mamona na face medial proximal da tíbia, com análise macroscópica e histopatológica aos 30 (GIII), 60 (GII) e 90 (GI) dias. RESULTADOS: A poliuretana foi recoberta por uma cápsula conjuntiva fibrosa, não ocorrendo proliferação óssea ao seu redor. CONCLUSÃO: A poliuretana é biocompatível, comportando-se como espaçador biológico em cães. Nesta espécie não ocorre a osteointegração.

Vitamin C and endogenous cortisol in foreign-body inflammatory response in pacus

O objetivo deste trabalho foi avaliar o efeito da suplementação com vitamina C no aumento da atividade de macrófagos e células gigantes multinucleadas (CGM), em pacus mantidos em duas densidades de estocagem. O experimento foi realizado em parcelas subdivididas, em arranjo fatorial 2x2x3 com: 0 e 500 mg kg-1 de vitamina C; densidade de estocagem de 5 e 20 kg m-3; e tempos de avaliação de 3, 6 e 12 dias após o implante subcutâneo (DPI) de lamínulas de vidro. Foram determinados o número de macrófagos e de CGM, bem como os níveis de cortisol e glicose no plasma. O número de macrófagos e de CGM com 2 a 5 núcleos foi significativamente maior nos peixes suplementados com vitamina C, à densidade 5 kg m-3, aos 3 DPI, em relação aos não suplementados. Constatou-se menor quantidade de macrófagos e CGM em peixes com baixa concentração plasmática de cortisol. A suplementação com 500 mg de vitamina C por quilograma de ração beneficia a atividade de macrófagos em inflamações do tipo corpo estranho, e a elevada concentração de cortisol circulante tem efeito supressor nesta resposta.
