The purpose of this study was to evaluate children with specific language impairment (SLI) and their proficiency with the use of prepositions. Ten children with SLI were compared to 10 younger, normally developing children matched for mean length of utterance and 10 children matched for age. Each child was asked to produce 24 sentences containing locative (in, on) and dative (to) prepositions. Responses were coded for omission or word selection errors for the target prepositions. It was hypothesized that children with SLI would make more errors than the typically developing children. Omission errors would support a difficulty with syntax because of the role prepositions play in case marking. Word selection errors would support a deficit in the area of semantics. The results confirmed that children with SLI made more errors than the control group. The children with SLI made more errors in the selection of dative prepositions, indicating a difficulty linking the semantics of prepositions and verbs.

Patients with Down syndrome may not be cooperative during dental treatment and, in cases of complex treatment, it is necessary to use oral or inhaled sedation and/or general anesthesia, which represent safe and efficient treatment resources. There are few reports about oral rehabilitation with dental implants in patients with Down syndrome in the literature. This paper presents the case of a patient with Down syndrome and moderate mental retardation who suffered avulsion of the maxillary left central incisor after a fall, and was treated by means of a single dental implant with immediate load carried out under general anesthesia. After 4 years of follow up, there has been improvement in the sleep obstructive apnea syndrome due to the use of a tongue crib adapted for providing esthetics and preserving the implant placed.

BackgroundGreen synthesis is an ecological technique for the production of well characterized metallic nanoparticles using plants. This study investigated the synthesis of silver nanoparticles (AgNPs) using a Caesalpinia ferrea seed extract as a reducing agent.MethodsThe formation of AgNPs was identified by instrumental analysis, including ultraviolet–visible (UV–Vis) spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD) of the AgNPs, and surface-enhanced Raman scattering (SERS) spectra of rhodamine-6G (R6G). We studied the physicochemical characterization of AgNPs, evaluated them as an antifungal agent against Candida albicans, Candida kruzei, Candida glabrata and Candida guilliermondii, and estimated their minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) values. Lastly, this study evaluated the cytotoxicity of the AgNPs in murine L929 fibroblasts cells using an MTT assay.ResultsThe UV–Vis spectroscopy, SERS, SEM and XRD results confirmed the rapid formation of spheroidal 30–50 nm AgNPs. The MIC and MFC values indicated the antifungal potential of AgNPs against most of the fungi studied and high cell viability in murine L929 fibroblasts. In addition, this study demonstrated that C. ferrea seed extracts may be used for the green synthesis of AgNPs at room temperature for the treatment of candidiasis.

O atendimento odontológico de pacientes surdos é considerado um desafio. A falta de contato dos estudantes com a Língua Brasileira de Sinais (Libras) durante a graduação pode ser um fator agravante da condição de saúde bucal desta população. Assim, o objetivo do estudo foi oferecer um panorama sobre a inclusão da disciplina de Libras nos projetos pedagógicos dos cursos de graduação em Odontologia da Região Sudeste do Brasil. Consiste em um estudo exploratório, quantitativo e transversal. As matrizes curriculares dos cursos foram analisadas, buscando-se as informações referentes às variáveis: categoria administrativa da Instituição de Ensino Superior (IES), oferta e natureza do componente curricular e carga horária. A população do estudo foi constituída por 176 IES, das quais 32 não disponibilizaram suas respectivas matrizes curriculares. Observou-se que 125 cursos (86,8%) eram de IES particulares e 19 (13,19%) de públicas, com 83 (57,63%) oferecendo o componente curricular Libras em sua matriz, sendo que 71 (91,02%) das 78 IES que disponibilizaram a informação ofertam o conteúdo como opcional ou eletivo. A carga horária variou de 30 a 80 horas, com média de 49,7h. Conclui-se que a implementação da Libras ainda é discreta nas universidades públicas e mais concentrada nas IES privadas, sendo, em sua maioria, não-obrigatória.
