Ecological perspectives on female and male reproductive success with competition in two Serapias species.

The deceptive strategies by which orchids are pollinated and how these are capable of attracting pollinators remain understudied with regard to their implications on plant fitness. Despite its ecological importance, limited investigations have been conducted on sexual deception and shelter mimicry in orchid species, making it a compelling avenue in orchid biology research. To expand the knowledge of these reproductive mechanisms, we studied the pollination of Serapias lingua and S. parviflora, in co-occurring and isolated sites in Balearic Islands (Spain), further accentuated by the presence of a hybrid, indicating shared pollinators. We employed bagging and hand pollination experiments to examine their reproductive biology. Furthermore, we evaluated the influence of phenotypical and ecological factors on reproductive success, including biometric measurements, reproductive performance and neighborhood diversity (co-flowering and pollinator communities). Reproductive mechanisms between these two orchid species exhibit substantial disparities. Serapias lingua relies primarily on insect-mediated pollination, while S. parviflora demonstrates self-reproduction capacity. Although events of open pollination are rare, hybridization occurs predominantly when S. lingua is the pollen donor. Fruit set in S. parviflora was positively correlated with plant height, while in S. lingua it was negatively associated with flower size. The coexistence of both species positively affected pollinia removal in S. parviflora, but did not exert an influence on reproductive traits in S. lingua. Overall, biometric parameters were diminished in isolated compared to co-occurring sites. At the community level, the increased diversity of co-flowering species in the vicinity exhibited an inhibitory effect on pollinia removal in S. parviflora. Under a context of pollinator loss or phenological mismatch between pollinator presence and flowering, the selfing capacity of S. parviflora would guarantee reproduction whereas S. lingua survival would be compromised. Furthers studies are needed to assess the effects of phenotypical and ecological factors on reproductive success of S. lingua in pollinator-decline scenarios.

A Case Report of a Co-Amoxiclav-Induced Black Hairy Tongue.

A black hairy tongue is a benign, self-limiting condition characterized by the discolouration of the tongue due to defective desquamation. Clinical presentation varies, with most cases being asymptomatic although aesthetically unpleasant to the patient. Prevalence varies geographically, ranging from 0.6% to 11.3%. It can be triggered by various factors such as medications, smoking, alcohol, poor oral hygiene, or even underlying systemic conditions such as malignancy. Several antibiotics such as doxycycline, erythromycin, amoxicillin-clavulanate, metronidazole, and piperacillin-tazobactam, have been reported to cause black hairy tongues. Onset can range from a few weeks to as long as five weeks. Diagnosis relies on clinical assessment with a good history and visual examination. Definitive treatment remains unclear, but the condition typically improves by identifying and discontinuing the causative agent and maintaining adequate oral hygiene. Complications are rare, and the prognosis is excellent. This case report aims to raise awareness of the association between the black hairy tongue and co-amoxiclav, which may impose additional burdens on patients, healthcare providers, and the health system if failed to be recognized and treated appropriately.

Casearia sylvestris var. lingua (Càmbess.) Eichler leaves aqueous extract improves colon inflammation through mucogenic, antioxidant and anti-inflammatory actions in TNBS- induced IBD rats.

ETHNOPHARMACOLOGICAL RELEVANCE: Casearia sylvestris var. lingua (Cambess.) Eichler, a member of the Salicaceae family, holds a prominent place in traditional medicine across various cultures due to its versatile therapeutic properties. Historically, indigenous communities have utilized different parts of the plant, including leaves, bark, and roots, to address a wide array of health conditions. Traditional uses of C. sylvestris var. lingua encompasses the treatment of gastrointestinal disorders, respiratory infections, wound healing, inflammation, and stomach ulcers. Pharmacological studies have demonstrated the plant's antimicrobial, anti-inflammatory, antioxidant, analgesic, gastroprotective, and immunomodulatory effects. This signifies the first scientific validation report for C. sylvestris var. lingua regarding its effectiveness against ulcerative colitis. The report aims to affirm the traditional use of this plant through pre-clinical experiments. AIM OF THE RESEARCH: This work uses an aqueous extract from C. sylvestris var. lingua leaves (AECs) to evaluate the acute anti-ulcerative colitis efficacy in rat and HT-29 (human colorectal cancer cell line) models. METHODS: To determine the secondary metabolites of AECs, liquid chromatography with a diode array detector (LC-DAD) study was carried out. 2,4,6-trinitrobenzenesulfonic acid (TNBS, 30 mg/0.25 mL EtOH 30% v/v) was used as an enema to cause acute colitis. Three days were spent giving the C. sylvestris var. lingua extract orally by gavage at dosages of 3, 30, and 300 mg/kg. The same route was used to deliver distilled water to the vehicle and naïve groups. After the animals were sacrificed on the fourth day, intestinal tissues were taken for histological examination and evaluation of biochemical tests such as those measuring superoxide dismutase (SOD), reduced glutathione (GSH), catalase (CAT), malondialdehyde (MDA), nitrite/nitrate, myeloperoxidase (MPO) activity. Additionally, interleukin 1 beta (IL-1ß), tumor necrosis factor alpha (TNF-α), and interleukin 10 (IL-10), were conducted on the intestinal tissues. Additionally, an MTT assay was used to evaluate the effect of AECs on the viability of HT-29 cells. Additionally, a molecular docking study was carried out to compare some potential target proteins with identified chemicals found in AECs. RESULTS: LC-DAD analysis identified five compounds (caffeic acid, ellagic acid, ferulic acid, gallic acid, and quercetin) in AECs. Pre-administration of AECs (3; 30; 300 mg/kg) and mesalazine (500 mg/kg) reduced macroscopic scores (55%, 47%, 45%, and 52%, p < 0.001) and ulcerated areas (70.3%, 70.5%, 57%, and 56%, p < 0.001), respectively. It also increased SOD, GSH, and CAT activities (p < 0.01), while decreasing MDA (p < 0.001), nitrite/nitrate (p < 0.05), and MPO (p < 0.001) activities compared to the colitis group. Concerning inflammatory markers, significant modulations were observed: AECs (3, 30, and 300 mg/kg) lowered levels of IL-1ß and TNF-α (p < 0.001) and increased IL-10 levels (p < 0.001) compared to the colitis groups. The viability of HT-29 cells was suppressed by AECs with an IC50 of 195.90 ± 0.01 µg/mL (48 h). During the molecular docking analysis, quercetin, gallic acid, ferulic acid, caffeic acid, and ellagic acid demonstrated consistent binding affinities, forming stable interactions with the 3w3l (TLR8) and the 3ds6 (MAPK14) complexes. CONCLUSION: These results imply that the intestinal mucogenic, anti-inflammatory, and antioxidant properties of the C. sylvestris var. lingua leaf extract may be involved in its therapeutic actions for ulcerative colitis. The results of the in silico study point to the possibility of quercetin and ellagic acid interacting with P38 and TLR8, respectively, in a beneficial way.

Verbal and nonverbal disagreement in an ELF academic discussion task.

Recent English as a Lingua Franca (ELF) studies have examined the linguistic features of disagreements during interactive academic tasks and casual conversations. Fewer studies, however, have explored nonverbal cues of disagreement, and even less is known about how interlocutors perceive disagreements. Therefore, using data from a corpus of ELF interaction, this study examined the verbal features and visual cues used by ELF university students to disagree during an academic discussion task. The disagreement episodes were selected through a content analysis of stimulated recall protocols in which a speaker stated that a disagreement had occurred. Transcripts were analyzed to classify the speaker's verbal strategies as being mitigated or unmitigated. Video recordings were examined for facial expressions, body movements, and hand gestures. Findings revealed that ELF students used mitigated linguistic strategies, such as hedges, during disagreement while gaze aversion, smiling, and head nods were the most frequent nonverbal cues. The stimulated recall data showed that disagreements were perceived as an opportunity to listen, think, and share different opinions. Implications are discussed in terms of how to interpret features of disagreement in language classrooms.

Ecology needs to overcome siloed modelling.

Bahlburg et al. re-implemented eight growth models of Antarctic krill and showed that their predictions are all over the place. The authors discuss the reasons for this and how more coherence in modelling could be achieved through systematic model comparison and integration. For this, we need a common language.

Casearia Essential Oil: An Updated Review on the Chemistry and Pharmacological Activities.

Casearia species are found in the America, Africa, Asia, and Australia and present pharmacological activities, besides their traditional uses. Here, we reviewed the chemical composition, content, pharmacological activities, and toxicity of the essential oils (EOs) from Casearia species. The EO physical parameters and leaf botanical characteristics were also described. The bioactivities of the EOs from the leaves and their components include cytotoxicity, anti-inflammatory, antiulcer, antimicrobial, antidiabetic, antioxidant, antifungal, and antiviral activities. The main components associated with these activities are the α-zingiberene, (E)-caryophyllene, germacrene D, bicyclogermacrene, spathulenol, α-humulene, ß-acoradiene, and δ-cadinene. Data on the toxicity of these EOs are scarce in the literature. Casearia sylvestris Sw. is the most studied species, presenting more significant pharmacological potential. The chemical variability of EOs components was also investigated for this species. Caseria EOs have relevant pharmacological potential and must be further investigated and exploited.

Carga das Doenças Crônicas Não Transmissíveis nos Países de Língua Portuguesa / The burden of Noncommunicable Diseases in Portuguese Language Countries

Resumo Foram analisadas tendências da mortalidade prematura por doenças crônicas não transmissíveis (DCNT) entre 1990 e 2019, as projeções até 2030 e os fatores de risco atribuíveis a estas doenças na Comunidade dos Países de Língua Portuguesa (CPLP). Utilizou-se estimativas do estudo Carga Global de Doenças e análise da carga de mortalidade prematura por DCNT para nove países da CPLP, utilizando taxas padronizadas por idade, usando-se RStudio. Portugal, Brasil, Guiné Equatorial, Angola e Guiné Bissau apresentam taxas de mortalidade prematura por DCNT em declínio e; Timor Leste, Cabo Verde, São Tomé e Príncipe e Moçambique apresentaram aumento das taxas. As projeções indicam que nenhum dos países deverá atingir as metas de redução em um terço da mortalidade prematura por DCNT até 2030. A carga de doença atribuível mostrou que os fatores de riscos mais importantes em 2019 foram: pressão arterial sistólica elevada, tabaco, riscos dietéticos, índice de massa corporal elevado e poluição do ar. Conclui-se pelas profundas diferenças na carga de DCNT entre os países, com melhores resultados em Portugal e Brasil e que nenhum país do CPLP deverá atingir a meta de redução das DCNT até 2030.

Abstract The present study analyzed trends in premature mortality from Noncommunicable diseases (NCDs) between 1990 and 2019, the projections up to 2030, and the risk factors (RFs) attributable to these diseases in the Community of Portuguese Language Countries (CPLP). Estimates from the Global Burden of Disease (GBD) study and the analysis of the burden of premature mortality due to NCDs were used for nine CPLP countries, applying age-standardized rates, using RStudio. Portugal, Brazil, Equatorial Guinea, Angola, and Guinea Bissau showed declining premature mortality rates caused by NCDs, while East Timor, Cape Verde, São Tomé and Príncipe, and Mozambique showed an increase in rates. Projections indicate that none of the countries is expected to achieve the goals of reducing premature mortality due to NCDs by one third by 2030. The attributable burden of disease showed that the most important RFs in 2019 were: high systolic blood pressure (SBP), tobacco, dietary risks, high body mass index (BMI), and air pollution. It can therefore be concluded that there are profound differences in the burden of NCDs among the countries, with better results in Portugal and Brazil, and that no CPLP country is likely to reach the NCD reduction target by 2030.

Diferença entre os vocábulos bucal e oral na terminologia odontológica e seus significados na língua portuguesa / Difference between oral and oral vocables in dental terminology and their meanings in portuguese language

O objetivo do presente trabalho foi discutir sobre a diferença entre os termos bucal e oral na Odontologia, tendo como respaldo a Língua Portuguesa. A metodologia bibliográfica buscou se ancorar em teóricos da linguagem e da Odontologia para investigar a diferença entre tais palavras. Após leitura de textos que versaram sobre essas vertentes, observamos que a principal diferença residiu na origem das palavras bucca e os, originárias do latim clássico e vulgar, respectivamente, com significados distintos. Todavia, ao migrarem para o português, os falantes escolheram o termo bucca em detrimento de os, o qual ainda hoje é usado ao lado de oral, com sentidos semelhantes. Notamos, ainda, que para os profissionais da saúde seria importante padronizar a terminologia, pois facilitaria a compreensão desses termos para pacientes e profissionais de outras áreas, tais como os tradutores; por outro lado, ficou nítido que, em alguns momentos, a unificação terminológica seria mais difícil, pois os contextos de uso teriam que ser mudados. Por fim, destacamos que estudar estes vocábulos no contexto da Odontologia é importante para que tanto pacientes quanto os profissionais de saúde, ou de áreas similares conheçam a peculiar diferença(AU)

The objective of the present work was to discuss the difference between the terms oral and oral in Dentistry, based on the Portuguese language. The bibliographic methodology sought to anchor in language and dentistry theorists to investigate the difference between such words. After reading texts that dealt with these aspects, we observed that the main difference resided in the origin of the word bucca and os, originating from classical and vulgar Latin, respectively, with different meanings. However, when migrating to Portuguese, the speakers chose the term bucca over os, which is still used alongside oral, with similar meanings. We also noted that for health professionals it would be important to standardize the terminology, as it would facilitate the understanding of these terms for patients and professionals from other areas, such as translators; on the other hand, it was clear that at times, terminological unification would be more difficult, as the contexts of use would have to be changed. Finally, we emphasize that studying these words in the context of Dentistry is important so that both patients and health professionals, or from similar areas, know the peculiar difference(AU)

Antimicrobial activity of violacein against oral bacteria associated with halitosis: an in vitro study

Introduction: violacein is a natural purple pigment produced by environmental bacteria that presents antimicrobial activity, particularly against Gram-positive bacteria. Intraoral halitosis (IOH) is a condition defined by the unpleasant odor emanating from the mouth, whose main source are volatile sulfur compounds, produced by Gram-negative oral bacteria on the tongue coating. In IOH treatment, antimicrobials have been indicated as chemical adjuncts, including natural products. Objective: thus, this study tested the antimicrobial activity of a violacein extract on key IOH-related bacteria (Porphyromonas gingivalis, Porphyromonas endodontalis, Fusobacterium nucleatum, Prevotella intermedia, Solobacterium moorei). Materials and Methods: bacteria were cultured in fastidious anaerobe blood agar in anaerobiosis, and 109 cells/ml suspensions were plated. Crude extract of violacein obtained from Chromobacterium violaceum was diluted in a 25% ethanol aqueous solution to 8, 4, 2, 1, 0.5 and 0.25 mg/ml. Using the disk agar diffusion method, 10 µl aliquots of each dilution were deposited on the seeded plates. Chlorohexidine (0.1%) and 25% ethanol solution were used as controls. Plates were incubated in anaerobiosis at 37°C for 72h, and the inhibition halos were recorded. Results: although chlorhexidine showed higher inhibition halos than the violacein extract, most species were inhibited at 4 and 8 mg/ml concentrations (p<0.05). P. gingivalis followed by F. nucleatum were the most affected species in relation to the other bacteria, although statistical significance was only reached for P. gingivalis (p<0.05). Conclusion: crude violacein extract from C. violaceum demonstrated antimicrobial activity against IOH-associated oral bacteria, being a potential antimicrobial to be studied as an adjunct in the control of IOH.

Introdução: a violaceína é um pigmento roxo natural produzido por bactérias ambientais que apresenta ação antimicrobiana, particularmente contra bactérias Gram-positivas. A halitose intraoral (HIO) é uma condição definida pelo odor desagradável que emana da boca, cuja principal fonte são os compostos sulfurados voláteis produzidos por bactérias Gram-negativas da saburra lingual. No tratamento da HIO, antimicrobianos têm sido indicados como adjuvantes, incluindo produtos naturais. Objetivo: assim, este estudo avaliou o potencial antimicrobiano de um extrato de violaceína em patógenos-chave da HIO (Porphyromonas gingivalis, Porphyromonas endodontalis, Fusobacterium nucleatum, Prevotella intermedia, Solobacterium moorei). Materiais e Métodos: bactérias foram cultivadas em meio ágar sangue para fastidiosos, em anaerobiose, e suspensões de 109 células/ml foram semeadas. O extrato bruto de violaceína obtido de Chromobacterium violaceum foi diluído em solução aquosa com 25% de etanol nas concentrações de 8, 4, 2, 1, 0,5 e 0,25 mg/ml. Através do método de disco difusão, 10 µl de cada diluição foram depositados nas placas semeadas. A clorexidina (0,1%) e a solução etanólica a 25% foram usadas como controles. As placas foram incubadas em anaerobiose a 37°C por 72h, e os halos de inibição foram registrados. Resultados: embora a clorexidina tenha apresentado os maiores halos de inibição do do que o extrato, a maioria das espécies foi inibida nas concentrações de 4 e 8 mg/ml (p<0,05). P. gingivalis e F. nucleatum foram as espécies mais afetadas em relação às outras bactérias, porém só foi observada significância estatística para P. gingivalis (p<0,05). Conclusão: o extrato bruto de violaceína de C. violaceum demonstrou atividade antimicrobiana contra bactérias orais associadas a HIO, sendo um potencial antimicrobiano a ser estudado como adjuvante no controle da HIO.

English linguistic neo-imperialism in the era of globalization: A conceptual viewpoint.

As Phillipson warned, "[l]inguistic imperialism [is] alive and kicking" and has become even more subtle in an era when English has become the global lingua franca. With this, this conceptual paper aims to propose features of linguistic neo-imperialism by describing how English has continuously spread and retained its power in various domains particularly in periphery countries, whether ex-colonies or non-colonies. Broadly, we highlight these features from the aspects of communication, business, academia, and education. The features of English linguistic neo-imperialism are interrelated and interactive in these fields, reinforcing the current dominant position of English. We then proceed with drawing implications for the local languages, particularly in their preservation and use alongside English and other dominant lingua francas.

Conclusão O fluxo expiratório nasal simétrico está associado com a posição de língua elevada e lábios fechados no REPOUSO; por outro lado, o fluxo expiratório nasal maior e/ou ausente em uma narina está associado com queixa materna de dificuldade do recém-nascido para respirar, posição de lábios abertos/entreabertos E posição de língua baixa no repouso, bem como, com movimentos repetidos de anteriorização de língua.

ABSTRACT Purpose To verify the association between breathing nasal expiratory flow and posture of lips and tongue at rest, presence of repeated forward movements of the tongue and maternal complaint of respiratory difficulty in the newborn in the first days of life. Method A observational study was carried out in 130 babies, in a university hospital. Included newborn with Apgar score greater than or equal to 8 in exclusive breast milk. It was the following data: position of lips and tongue at rest, nasal expiratory flow and maternal complaint of difficulty in breathing in the newborn. The data were subjected to statistical analysis using the tests, Fisher's exact test and the Chi-Square test, adopting a significance level of 5% . Results there was a significant association between maternal complaint of newborn difficulty breathing with repeated forward tongue movements and nasal expiratory flow; tongue position with resting lips position at rest, repeated tongue forward movements with nasal expiratory flow and tongue position at rest; nasal expiratory flow exit with tongue position at rest. Conclusion Symmetrical nasal expiratory flow is associated with an elevated tongue position and closed lips at rest; on the other hand, increased and/or absent nasal expiatory flow in one nostril is associated with maternal complaints of difficulty in breathing, open/ half-open lips position and low tongue position during rest, as well as, repeated forward tongue movements.

Correlação entre achados da avaliação clínica miofuncional orofacial, a pressão e a atividade eletromiográfica da língua na deglutição em indivíduos com diferentes alterações da motricidade orofacial / Correlation between findings of the oral myofunctional clinical assessment, pressure and electromyographic activity of the tongue during swallowing in individuals with different orofacial myofunctional disorders

RESUMO Objetivo correlacionar os achados da avaliação clínica miofuncional orofacial, pressão de língua e da eletromiografia de superfície (EMGs) da deglutição de grupos de pacientes com diferentes alterações da motricidade orofacial. Método 44 pacientes (20 homens e 24 mulheres com idades entre 17 e 63 anos), com diferentes alterações miofuncionais orofaciais foram avaliados por meio da Avaliação Miofuncional Orofacial com Escores Expandido (AMIOFE-E), avaliação da amplitude mandibular e antropometria facial, mensuração da pressão de língua (ponta e dorso) e exame de Eletromiografia de Superfície (EMGs) em região supra hioidea na tarefa de deglutição de saliva e diferentes volumes de água. Resultados a análise estatística encontrou algumas correlações fracas que envolvem a pressão do dorso de língua e sugerem que quanto maior for a medida do terço inferior, menor será a pressão do dorso da língua; quanto maior for a medida dos trespasses (vertical e horizontal) maior será a pressão do dorso da língua; quanto maior for a pontuação da avaliação de postura e funções orofaciais, maior será a pressão do dorso de língua e quanto maior for a pressão do dorso de língua, maior será a pressão da ponta da língua. Conclusão os resultados sugerem que as alterações miofuncionais orofaciais encontradas nos diferentes grupos de pacientes estão mais relacionadas às discrepâncias maxilomandibulares do que às patologias pesquisadas no presente estudo.

ABSTRACT Purpose To correlate the findings regarding the myofunctional orofacial examination, tongue pressure and surface electromyography (sEMG) of deglutition in individuals with different orofacial myofunctional disorders. Methods 44 patients (20 males and 24 females, aged between 17 and 63 years old) with different orofacial myofunctional changes were clinically assessed using the Expanded Protocol of Orofacial Myofunctional Evaluation with Scores (OMES-E). In addition, the range of mandibular movements and facial anthropometry were measured, along with the assessment of the tongue pressure (tip and dorsum) and of the electrical activity of the suprahyoid muscles during deglutition, using surface electromyography (sEMG). Results The statistical analysis found weak correlations between tongue dorsum pressure values, suggesting that the greater the measurement of the lower third of the face, the lower the pressure of the tongue dorsum; the greater the measurement of the overlaps (vertical and horizontal), the higher the pressure of the tongue dorsum; the higher the score from the orofacial evaluation and orofacial functions assessment, the higher the pressure of the tongue dorsum; and the higher the pressure of the tongue dorsum, the higher the pressure of the tongue tip. Conclusion The present study results indicate that the orofacial myofunctional changes found in different groups of patients are more related to the maxillomandibular discrepancies than to the pathologies investigated herein.

Percepção de sintomas osteomusculares e sua repercussão nas atividades de vida diária em intérpretes de língua de sinais / Musculoskeletal symptoms perception and its impact on language interpreters' daily lives

Resumo Objetivo: analisar a percepção de sintomas osteomusculares e sua repercussão nas atividades de vida diária referidas por intérpretes da língua brasileira de sinais (libras). Métodos: pesquisa qualitativa de natureza descritiva-analítica, utilizando a análise de conteúdo categorial temática. Foi aplicado questionário sociodemográfico e realizada entrevista semiestruturada com 12 profissionais intérpretes de libras, atuantes nas redes de ensino nos níveis fundamental, médio e superior do município de Goiânia, convidados via redes sociais, no primeiro semestre de 2021. Resultados: foram identificadas três categorias temáticas: percepção álgica, percepção de cansaço e atividades de vida diária. Os profissionais estavam trabalhando remotamente devido à pandemia da doença COVID-19, cujo regime permitiu uma flexibilização do processo de trabalho com aulas on-line, eventos, palestras e congressos a partir do domicílio do trabalhador. Houve um aumento expressivo da demanda física e psicológica, devido ao aumento das atividades a serem cumpridas e por estarem ausentes os limites entre ambiente de "trabalho" e "casa". Conclusão: os participantes apresentaram percepções negativas em todos os aspectos avaliados, evidenciando a existência de sobrecarga na atuação como intérprete de língua de sinais.

Abstract Objective: to analyze the perception of musculoskeletal symptoms and their repercussion in the activities of daily living reported by professional Brazilian sign language interpreters (LIBRAS). Methods: descritive-analytical qualitative research, using thematic categorical content analysis. We used a sociodemographic questionnaire and a semi-structured interview with 12 professional LIBRAS interpreters, working in the primary, secondary, and superior education in the municipality of Goiânia. They were invited via social media, in the first half of 2021. Results: we identified three thematic categories: pain perception, perception of tiredness, and activities of daily living. The professionals were working remotely due to the COVID-19 pandemic. This allowed flexibility in the work schedule, with online classes, events, lectures, and congresses participation from the worker's home. Conclusion: the participants had negative perceptions in all aspects evaluated, evidencing an overload in acting as a sign language interpreter in educational activities.

Hemangioma intramuscular con flebolitos de lengua. Reporte de un caso clínico-patológico

Se presenta un caso de hemangioma intramuscular con flebolitos de lengua en una mujer de 60 años. Clínicamente correspondía a una tumefacción de dos años de evolución, sin signos que sugirieran su origen vascular. Luego de su evaluación inicial se realizó biopsia excéresis de la lesión para su estudio histopatológico. En el estudio histológico se pudo observar una formación tisular redondeada y circunscripta constituida por tejido conjuntivo fibroso con abundantes capilares congestivos que desplazaban el tejido muscular, destacándose la presencia de trombos con calcificaciones dispuestas en capas concéntricas (flebolitos). En base a estos hallazgos morfológicos, el diagnóstico definitivo fue de hemangioma capilar intramuscular con flebolitos de lengua. Para confirmar la naturaleza neoplásica vascular de la lesión se realizó inmunomarcación con el anticuerpo GLUT1. Es de destacar, de acuerdo a la revisión bibliográfica realizada en PubMed, que esta entidad patológica es rara, particularmente en la lengua.

Apresentamos um caso de hemangioma intramuscular com flebólitos de língua em uma mulher de 60 anos. Clinicamente, correspondia a um inchaço com duração de dois anos, sem sinais que sugerissem sua origem vascular. Após sua avaliação inicial, foi realizada biópsia excisional da lesão para estudo histopatológico. No estudo histológico pôde-se observar uma formação tecidual arredondada e circunscrita constituída por tecido conjuntivo fibroso com abundantes capilares congestivos que deslocavam o tecido muscular, destacando a presença de trombos com calcificações dispostos em camadas concêntricas (flebólitos). Com base nesses achados morfológicos, o diagnóstico definitivo foi de hemangioma capilar intramuscular com flebólitos de língua. Para confirmar a natureza neoplásica vascular da lesão, foi realizada imunocoloração com o anticorpo GLUT1. Ressalta-se, de acordo com a revisão bibliográfica realizada no PubMed, que esta entidade patológica é rara, principalmente na língua.

Summary We present a case of intramuscular hemangioma with tongue phleboliths in a 60-year-old woman. Clinically it corresponded to a swelling of two years of evolution, without signs that suggested its vascular origin. After her initial evaluation, an excisional biopsy of the lesion was performed for histopathological study. In the histological study it was possible to observe a rounded and circumscribed tissue formation made up of fibrous connective tissue with abundant congestive capillaries that displaced the muscle tissue, highlighting the presence of thrombi with calcifications arranged in concentric layers (phleboliths). Based on these morphological findings, the definitive diagnosis was intramuscular capillary hemangioma with tongue phleboliths. To confirm the vascular neoplastic nature of the lesion, histochemical immunostaining was performed with the GLUT1 antibody. It is noteworthy, according to the bibliographic review carried out in PubMed, that this pathological entity is rare, particularly in the tongue.

Abordagem interdisciplinar no tratamento da macroglossia na síndrome de Beckwith-Wiedemann: relato de caso / Interdisciplinary approach in the treatment of macroglossia in Beckwith-Wiedemann syndrome: case report

RESUMO O objetivo deste estudo foi relatar a abordagem interdisciplinar no manejo da macroglossia em um caso de paciente com síndrome de Beckwith-Wiedemann, no período de dez anos. O acompanhamento iniciou pela equipe de Cirurgia Bucomaxilofacial, seguido da Fonoaudiologia, em função de dificuldades alimentares. Após avaliação clínica e instrumental, aos 8 meses de idade, iniciou-se a intervenção fonoaudiológica com foco na disfagia orofaríngea e na terapia miofuncional orofacial. Foi verificado, com 1 ano e 11 meses, ausência de sinais de alteração de deglutição em fase faríngea e melhora na postura de lábios e língua. Aos 3 anos, foram iniciados estímulos para retirada dos hábitos orais e o treino da função mastigatória. O tratamento ortodôntico para correção de mordida aberta anterior e mordida cruzada posterior unilateral iniciou-se aos 6 anos. Aos 7 anos e 5 meses de idade, constatou-se estabilidade do modo respiratório nasal e adequação da postura de repouso de lábios e língua. Aos 9 anos, em função de recidiva das alterações oclusais, optou-se pela redução cirúrgica da língua seguida de terapia miofuncional orofacial, retomada aos 9 anos e 3 meses. O resultado foi a correção da postura da língua na deglutição e a adequação da fala. A associação dos tratamentos, envolvendo Fonoaudiologia, Ortodontia e Cirurgia Bucomaxilofacial foi considerada efetiva no manejo da macroglossia, resultando na adequação e equilíbrio das funções orofaciais.

ABSTRACT This study aims to report the interdisciplinary management of macroglossia in a Beckwith-Wiedemann syndrome patient during ten years. Clinical follow-up started by the Oral and Maxillofacial Surgery team, followed by Speech Therapy due to feeding difficulties. After clinical and instrumental evaluation, at 8 months old, the speech therapy intervention was indicated, focusing on oropharyngeal dysphagia and orofacial myofunctional therapy. At 1 year and 11 months, no signs of swallowing alteration in the pharyngeal phase and improvement in the posture of the lips and tongue were found. At the age of 3, stimulation to remove oral habits and train masticatory function were initiated. Orthodontic treatment to correct anterior open bite and unilateral posterior crossbite started at age 6. At 7 years and 5 months, there was stability in the nasal breathing mode and adequacy of resting posture of lips and tongue. At the age of 9, due to relapse of the occlusal alterations, surgical reduction of the tongue was indicated, followed by orofacial myofunctional therapy, restarted at the age of 9 years and 3 months. The result was the correction of the posture of the tongue during swallowing and speech adequacy. The association of treatments involving Speech Therapy, Orthodontics and Oral and Maxillofacial Surgery was considered effective in the management of the macroglossia. It resulted in the adequacy and equilibrium of orofacial functions.

Afasias e construção de sentido: estudo com foco em história em quadrinhos / Aphasia and construction of meaning: study focused on comic strips

RESUMO Objetivo observar, na linguagem em afasia de sujeitos adultos, a constituição de sentidos, considerando a (re)organização enunciativa na leitura e na escrita. Métodos pesquisa qualitativa com método aplicado e exploratório e perspectiva de análise enunciativa sobre a linguagem, tendo as noções de forma e sentido como base analítica. Foi realizada uma atividade com três sujeitos com afasia (Bir, Cr e Aul), integrantes do Grupo Interdisciplinar de Convivência (GIC), formado por participantes com e sem afasia. Tal atividade consistiu em (re)organizar quadrinhos de uma história, visando constituir sentido, uma vez que a leitura/escrita de textos são habilidades comumente comprometidas nas afasias. Resultados a categoria de tempo crônico mostra-se fundante para elaboração das narrativas dos sujeitos com afasia. Entretanto, eles encontraram formas distintas de sustentação de sentidos, mas sempre atrelados a experiências provenientes da relação entre homem e mundo. Conclusão as narrativas foram organizadas/construídas pelos participantes, tendo por base as imagens (base formal) - uma vez comprometida a habilidade de leitura de textos verbais. Bir, Cr e Aul usaram o tempo crônico como eixo organizacional de suas narrativas e suas histórias em quadrinhos, demonstrando que promovem leitura e escrita ao se considerar o viés enunciativo de análise da linguagem.

ABSTRACT Purpose to observe , in the language of aphasic adult subjects, the constitution of meanings, considering the enunciative (re)organization in reading and writing. Methods qualitative research with applied and exploratory methods and a perspective of enunciative analysis on language, using the notions of form and meaning as analytical base. From an activity performed by three subjects with aphasia (Bir, Cr and Aul), members of the Interdisciplinary Coexistence Group (GIC), formed by participants with and without aphasia, which constituted of (re)organizing the panels (frames) of a comic strip, in order to constitute meaning - since the reading/writing of texts are skills that are commonly affected in aphasia. Results the chronic time category shows itself to be fundamental for the elaboration of the narratives of the subjects with aphasia, however they found different ways of sustaining meanings, but always linked to experiences arising from the relationship between man and world. Conclusion the narratives were organized/constructed by the participants, having the images as a base (formal base) - since the ability to read verbal texts is impaired. Bir, Cr and Aul used chronic time as an organizational axis of their narratives and their comic strips show that these subjects with aphasia promote reading and writing when considering enunciative bias of language analysis.
