Contrast-enhanced ultrasound (CEUS): one step forward in the identification of "high risk" solitary fibrotic tumors of the liver.

BACKGROUND: Solitary fibrous tumors of the liver (SFTL) are rare neoplasms, whose identification and definition of malignant potential are challenging. CASE PRESENTATION: A 62-year-old patient underwent conventional imaging and CEUS to characterize an indeterminate liver lesion after other imaging techniques were inconclusive. In fact, all diagnostic techniques concluded that it was a partially fibrotic lesion, while CEUS determined its extra-hepatocellular origin and malignant potential, initially hypothesized to be a cholangiocarcinoma. Due to the possible risk of seeding following a biopsy procedure, the patient was a candidate for surgery. Subsequently, histopathological examination revealed SFTL. CONCLUSION: CEUS confidently characterized the malignancy and hypothesized the origin of the liver lesion, thus aiding in treatment planning.

Investigating the impacts of personality on the use and perceptions of online collaborative platforms in higher education.

Collaborative work is a critical component of active learning. Where in-person collaboration may not be possible, inclusion of online collaboration tools has become more prevalent. Previous studies have suggested that online collaboration is beneficial to overall learning outcomes; however, little research has investigated how differences in personality traits, such as extraversion and agreeableness, impact the benefits and effectiveness of collaborative learning, both through online (synchronous and asynchronous) and in-person platforms. In the present study, 360 (66.4% female) undergraduate students completed an online survey to assess perceptions of and beliefs about online synchronous, online asynchronous, and in-person collaboration in higher education with a focus on the impact of extraversion and agreeableness. Findings indicated that students had more experience and greater preference for online synchronous collaboration compared to online asynchronous collaboration; however, students believed that in-person collaboration was most effective. Both extraversion and agreeableness predicted positive beliefs about group work in both online and in-person settings but not uniformly. These findings support the use of online synchronous collaboration when in-person opportunities are limited; however, individual differences related to personality traits can differentially impact students' perceptions toward and actions within collaboration contexts.

Fonoaudiologia e educação infantil: uma parceria necessária / Speech therapy and infantile education: a necessary partnership

OBJETIVO: investigar as informações que os professores de educação infantil possuem em relação a Fonoaudiologia na escola, bem como sobre temas ligados à área de linguagem. MÉTODOS: foi aplicado um questionário, contendo 17 questões objetivas em uma amostra com 73 professores de educação infantil da rede municipal de ensino da cidade de Maceió-AL. RESULTADOS: os participantes relacionaram a atuação fonoaudiológica na escola à presença de alterações no desenvolvimento da criança. O índice de professores da amostra que obtiveram contato com o fonoaudiólogo na escola é de 4,1 por cento. Estes educadores relatam que apenas 57,5 por cento receberam informações sobre a aquisição de linguagem e o desenvolvimento da escrita. CONCLUSãO: com a realização da presente pesquisa foi possível confirmar a necessidade de reforçar as ações fonoaudiológicas na escola, bem como a parceria entre fonoaudiólogos e professores.
