ABSTRACT

Abstract The aim of this study is to examine the dorsal lingual epithelium of the peregrine falcon (Falco peregrinus) of the family Falconidae. The tongue in its dorsal, lateral and ventral surfaces is covered with a non-keratinized multilayered stratified squamous epithelium. Lamina propria is present beneath the epithelial layers. Morphometrically, thickness of the apex tongue epithelium is more than that in the tongue body. Thickness of the ventral surface of the tongue is less than that in the dorsal one. Thickness of the lateral surface of the tongue was thicker than that in the ventral one and tongue body. Large and small conical papillae appeared on the posterior dorsal surface of the lingual body. There are lingual glands in certain areas of tongue body with numerous openings through the dorsal surface.


Resumo O objetivo deste estudo é examinar o epitélio lingual dorsal do falcão peregrino (Falco peregrinus) da família Falconidae. A língua em suas superfícies dorsal, lateral e ventral é coberta por um epitélio escamoso estratificado de múltiplas camadas não queratinizado. A lâmina própria está presente abaixo das camadas epiteliais. Morfometricamente, a espessura do epitélio do ápice da língua é maior do que a do corpo da língua. A espessura da superfície ventral da língua é menor do que a dorsal. A espessura da face lateral da língua foi mais espessa do que na ventral e no corpo da língua. Papilas cônicas grandes e pequenas apareceram na superfície posterior dorsal do corpo lingual. Existem glândulas linguais em certas áreas do corpo da língua com numerosas aberturas na superfície dorsal.

ABSTRACT

Resumen La lengua negra pilosa (LNP) es una alteración benigna caracterizada por coloración oscura e hipertrofia con hiperqueratosis en las papilas filiformes de la superficie de la lengua. Han sido implicados varios factores intrínsecos y extrínsecos como causales, entre ellos la pobre higiene dental, el tabaquismo, la ingesta de bebidas oscuras, el uso de antibióticos y algunas patologías malignas. Reportamos el caso de un paciente con carcinoma escamocelular avanzado de esófago medio conjunto con LNP, asociación no encontrada previamente en la literatura.


Abstract Black hairy tongue (BHT) is a benign disorder characterized by dark coloration and hypertrophy with hyperkeratosis in filiform papillae on the surface of the tongue. Several intrinsic and extrinsic factors, including poor dental hygiene, smoking, drinking dark beverages, indiscriminate use of antibiotics, and some malignant diseases, have been proposed as potential causes. This is the case of a patient with advanced squamous cell carcinoma of the mid esophagus in conjunction with BHT, a previously unknown association.

ABSTRACT

El fibroma de fibroblastos gigantes (FFG), conocido también como fibroma de células gigantes, es una pápula o nódulo asintomático localizado en la encía, paladar y lengua, es del mismo color que la mucosa adyacente, de base sésil o pediculada, con superficie lisa o papilar que por lo general mide menos de 1 cm. Objetivo: Identificar las características demográficas e histopatológicas de los casos de FFG de un laboratorio privado de patología bucal en la Ciudad de México. Material y métodos: Se obtuvieron los datos de edad, sexo, diagnóstico presuntivo y definitivo de 122 casos de FFG de 2004 a 2019 con un total de 7,681 muestras. Se describe su distribución por edad, sexo y localización. Resultados: El rango de edad obtenido es de 1 a 84 años, con un promedio de X = 38 años, se presenta con mayor frecuencia en la segunda década de vida, con una razón de 1.6:1 mujer a hombre. La localización más frecuente es en lengua (46%); sin embargo, sólo 49.1% de los estudios especificaban este dato. Conclusión: La importancia de esta lesión es que clínicamente se parece a otras patologías de tejido fibroso, por lo tanto, se debe tener presente al FFG como diagnóstico diferencial (AU)


Giant cell fibroma (GCF) is an asymptomatic papule or nodule that is similar in color to the surrounding mucosa, with a sessile or pedunculated base. It is usually less than 1 cm in size and it features a smooth or papillary surface. Objective: To identify the demographic and histopathological characteristics of GCF cases in a private oral pathology laboratory in Mexico City. Material and methods: Data on age, sex, as well as on presumptive and definitive diagnosis of 122 GCF cases were obtained from 2004 to 2019 with a total of 7,681 samples. Its distribution by age, sex and localization is described. Results: The age range obtained is from 1 to 84 years, with a mean age of 38 years. Frequently during the second decade of life, the female to male ratio is 1.6:1. The most frequent location is the tongue (46%), however, only 60 of 122 studies specified this data. Conclusion: Since this lesion clinically resembles another fibrous tissue pathology, it is warranted to have prior knowledge on its clinical characteristics, as GCF should be regarded as a differential diagnosis (AU)

ABSTRACT

OBJECTIVES@#This study aims to explore the effect of acidic culture conditions on the proliferation, apoptosis, and migration ability of human tongue squamous cell carcinoma SCC15 and CAL27 cells and its potential molecular mechanism.@*METHODS@#After acidic culture for different periods, methyl thiazolyl tetrazolium (MTT) method was adop-ted to detect the cell proliferation of SCC15 and CAL27. Flow cytometry was employed to detect the apoptosis level of SCC15 and CAL27 cells. The migration ability of SCC15 and CAL27 after acidic culture was detected by scratch hea-ling test. Real-time fluorescence quantitative polymerase chain reaction (FQ-PCR) was used to detect the mRNA expression of cyclooxygenase 2 (COX-2) and survivin in SCC15 and CAL27 cells after acidic culture.@*RESULTS@#After culture for 24 h under acidic microenvironment, SCC15 and CAL27 cells grew rapidly and reached the stationary phase after adjustment for 3 days. The apoptosis levels of SCC15 and CAL27 cells decreased after acidic culture, but the most significant reduction occurred after 6 h of acidic culture. The scratch healing rates of SCC15 and CAL27 cells increased after acidic culture. The results of FQ-PCR showed that the mRNA expression levels of COX-2 and survivin in SCC15 and CAL27 cells increased after acidic culture.@*CONCLUSIONS@#Extracellular acidic microenvironment can inhibit the apoptosis of tongue squamous carcinoma cells, promote their migration, and induce more adaptable and malignant tongue squamous carcinoma cells. The mechanism may be related to COX-2 and survivin and their signal pathways.

ABSTRACT

OBJECTIVES@#This study aims to investigate the effect of RhoE expression on the migration and invasion of tongue squamous cell carcinoma (TSCC).@*METHODS@#Forty-eight TSCC cases were selected from the Maxillofacial Surgery Center of Qingdao Municipal Hospital from 2017 to 2019. The expression of RhoE in the specimens (TSCC and adjacent tissues) was detected by immunohistochemistry, and RhoE mRNA and protein were extracted to further detect the expression of RhoE. SCC-4 and CAL-27 cells were selected for @*RESULTS@#The expression level of RhoE in TSCC was significantly lower than that in adjacent tissues (@*CONCLUSIONS@#RhoE expression is low in TSCC. Over expression RhoE in TSCC can significantly decrease its migration and invasion abilities. Hence, RhoE may play an important role in regulating the metastasis and invasion of TSCC and provide a new target for gene therapy.

ABSTRACT

OBJECTIVES@#The effect of isoprenylcysteine carboxymethyltransferase (ICMT) silencing on the migration and invasion of tongue squamous cell carcinoma was investigated by constructing the small interfering RNA (siRNA) of ICMT.@*METHODS@#Through liposomal transfection, siRNA was transfected into human tongue squamous cell carcinoma CAL-27 and SCC-4 cells (ICMT-siRNA group) with a negative control group (transfected with NC-siRNA) and a blank control group (transfected with a transfection reagent but not with siRNA). Quantitative real-time polymerase chain reaction was performed to analyze the mRNA expression of ICMT and RhoA in each group of cells after transfection and to measure the silencing efficiency. Western blot was applied to examine the expression levels of ICMT, total RhoA, membrane RhoA, ROCK1, matrix metalloproteinase (MMP)-2, and MMP-9 proteins in each group. The migration and invasion abilities were evaluated via wound healing and Transwell motility assays.@*RESULTS@#After CAL-27 and SCC-4 cells were transfected with ICMT-siRNA, the expression levels of ICMT genes and proteins decreased significantly in the experimental group compared with those in the negative and blank control groups (@*CONCLUSIONS@#The migration and invasion abilities of CAL-27 and SCC-4 cells were reduced significantly after the transfection of ICMT-siRNA, and the involved mechanism might be related to the RhoA-ROCK signaling pathway.

ABSTRACT

OBJECTIVES@#A study was conducted to investigate the molecular mechanism of chromodomain helicase/ATPase DNA binding protein 1-like gene (CHD1L) influencing the invasion and metastasis of tongue squamous cell carcinoma and to provide a new target for clinical inhibition of invasion and metastasis of tongue squamous cell carcinoma.@*METHODS@#Ualcan website was used to analyze the expression of CHD1L in normal epithelial tissue and primary head and neck squamous cell carcinoma and to analyze the effect of lymph node metastasis on the expression of CHD1L in tissues with head and neck squamous cell carcinoma. The relationship between CHD1L expression and the survival rate of patients with head and neck squamous cell carcinoma was tested by the GEPIA website. Western blot was used to quantify the levels of CHD1L protein in human tongue squamous cell carcinoma CAL27 and immortalized human skin keratinocyte cell HaCaT. After knocking down CAL27 in human tongue squamous cell carcinoma cells with an RNA interference plasmid, the cells were designated as SiCHD1L/CAL27 and Scr/CAL27. Western blot was utilized to detect the expression of CHD1L in each group of cells. The change in CAL27 cell proliferation ability was tested by EdU proliferation test after CHD1L knockdown. The change of cell migration ability of each group cells was tested through the wound healing assay. Western blot was used to detect epithelial-mesenchymal transition (EMT) marker E-cadherin and Vimentin protein expression levels.@*RESULTS@#Ualcan database showed that the expression of CHD1L in primary head and neck squamous cell carcinoma tissues was higher than in normal epithelial tissues and in head and neck squamous cell carcinoma tissues with lymph node metastasis. GEPIA website analysis showed that the overall survival rate of patients with head and neck squamous cell carcinoma with high expression of CHD1L was significantly lower than that of patients with low expression. Western blot results showed that CHD1L expression in human tongue squamous carcinoma cells CAL27 was higher than that of human normal skin cells HaCaT. CHD1L expression in SiCHD1L/CAL27 cells was much lower than that in Scr/CAL27 cells. Results of EdU proliferation experiments showed the significant reduction in the cell proliferation ability of the SiCHD1L/CAL27 cells. Results of the wound healing experiments showed the reduction in the migration capacity of the SiCHD1L/CAL27 cells. The expression of E-cadherin increased, whereas that of Vimentin decreased, in SiCHD1L/CAL27 cells.@*CONCLUSIONS@#CHD1L promoted the EMT, proliferation, migration, and invasion ability of tongue squamous cell carcinoma cells.

ABSTRACT

OBJECTIVES@#This study aimed to explore the effects of silencing isoprenylcysteine carboxyl methyltransfe-rase (Icmt) through small interfering RNA (siRNA) interference on the proliferation and apoptosis of tongue squamous cell carcinoma (TSCC).@*METHODS@#Three siRNA were designed and constructed for the Icmt gene sequence and were then transfected into TSCC cells CAL-27 and SCC-4 to silence Icmt expression. The tested cells were divided as follows: RNA interference groups Icmt-siRNA-1, Icmt-siRNA-2, and Icmt-siRNA-3, negative control group, and blank control group. The transfection efficiency of siRNA was detected by the fluorescent group Cy3-labeled siRNA, and the expression of Icmt mRNA was screened by quantitive real-time polymerase chain reaction (qRT-PCR) selected the experimental group for subsequent experiments. The expression of Icmt, RhoA, Cyclin D1, p21, extracellular regulated protein kinases (ERK), and phospho-extracellular regulated protein kinases (p-ERK) were analyzed by Western blot. The proliferation abilities of TSCC cells were determined by cell counting kit-8 assay. The change in apoptosis was detected by AnnexinV-APC/propidium staining (PI) assay. Cell-cycle analysis was conducted by flow cytometry.@*RESULTS@#The expression of Icmt mRNA and protein in TSCC cells significantly decreased after Icmt-siRNA transfection (@*CONCLUSIONS@#Silencing Icmt can effectively downregulate its expression in TSCC cells, reduce the RhoA membrane targeting localization and cell proliferation, and induce apoptosis. Thus, Icmt may be a potential gene therapy target for TSCC.

ABSTRACT

ABSTRACT Purpose Verify the position of lips and tongue at rest in newborns with and without ankyloglossia. Methods Cross-sectional study, carried out with 130 newborns in University Hospital. Data collection was performed by the researcher and speech-language pathologists from the Hospital. Information on gestational age, sex, weight, height and days of life was collected. The position of the lips and tongue at rest was evaluated through visual inspection with the newborns asleep. After the newborns were awakened, Neonatal Screening of the validated Protocol for the evaluation of the lingual frenulum for infants was performed to detect the alteration of the lingual frenulum. The data obtained were described and submitted to statistical analysis using the Chi-Square test to verify the association between the position of the lips with the tongue and to compare the position of the lips and tongue with and without ankyloglossia. The Mann-Whitney test was used to verify the behavior of the variables the differed between newborns with and without ankyloglossia. The significance level of 5% was adopted. Results When comparing the data, a significant difference was found between: weight and height with and without ankyloglossia; position of lips and tongue. An association between the position of the tongue and lips with and without ankyloglossia was also found. Conclusion Newborns without alteration of the lingual frenulum have a tendency to remain with their lips closed and their tongue elevated during rest and newborns with ankyloglossia have a tendency to keep their lips parted and their tongue low during rest.

ABSTRACT

RESUMO Objetivo Sintetizar o estado do conhecimento científico sobre biomecânica da língua durante a deglutição após laringectomia total. Estratégia de pesquisa Formulou-se a questão PICO e combinações de descritores e termos livres para busca nas bases de dados PubMed/Medline, EMBASE, LILACS e SciELO. Critérios de seleção incluíram-se artigos nos idiomas português, inglês ou espanhol; sem limite de tempo; com resultados sobre a biomecânica da língua durante a deglutição em laringectomizados totais; e estudos do tipo ensaio clínico randomizado ou não randomizado, coorte, caso controle, transversal, série de casos e estudos de caso. Análise dos dados analisou-se ano, país, população, objetivo, delineamento do estudo, instrumentos de avaliação, principais desfechos e qualidade metodológica. Resultados Foram incluídos quatro estudos realizados nos Estados Unidos, um na Austrália e um no Brasil, publicados entre 1986 e 2014. Em todos os estudos incluídos a biomecânica da língua foi um desfecho secundário. A maioria dos artigos teve baixa qualidade metodológica, com amostras pequenas, predomínio do sexo masculino e desenho transversal prevalente. Os instrumentos de avaliação foram videofluoroscopia, manometria, acelerômetro ou dispositivo para captar pressão de língua. Resultados principais indicaram mais força de propulsão da base de língua para superar a alta resistência da neofaringe ao fluxo do bolo alimentar; redução do contato e pressão entre base de língua e parede posterior da faringe; resíduo em base de língua após deglutição; pressão aumentada e resistência reduzida da língua oral. Conclusão Existem indícios de movimentos compensatórios de língua durante a deglutição após laringectomia total, porém, as evidências científicas são insuficientes.


ABSTRACT Purpose To synthesize the state of scientific knowledge about biomechanics of the tongue during swallowing after total laryngectomy. Research strategy The PICO question and combinations of descriptors and single terms were formulated in the PubMed/Medline, EMBASE, LILACS, and SciELO databases. Selection criteria Articles in Portuguese, English, or Spanish were included, without time limit, with results on the biomechanics of the tongue during swallowing and total laryngectomy, and studies on randomized or non-randomized clinical trials, cohort, case control, cross-sectional, case series, and case studies. Data analysis year, country, population, objective, study design, assessment methods, main outcomes, and methodological quality were analyzed. Results There were four studies in the United States, one in Australia, and one in Brazil, all published between 1986 and 2014. In all studies, the biomechanics of the tongue was the secondary outcome. Most articles had low methodological quality, small samples, predominance of the male gender, and a prevalent cross-sectional design. The assessment instruments were fluoroscopy, manometry, accelerometer or a device to capture tongue pressure. Main results indicated a higher propulsion force of the tongue base to overcome the high resistance of the neopharynx to the bolus flow, reduced contact and pressure between the base of the tongue and the posterior pharyngeal wall, residues in the tongue base after swallowing, increased pressure, and reduced resistance of the oral tongue. Conclusion There are indications of compensatory tongue movements during swallowing after total laryngectomy; however, the scientific evidence is insufficient.

ABSTRACT

RESUMO Objetivo Analisar o efeito imediato da hidratação de superfície laríngea associado à técnica de vibração sonorizada de língua (TVSL) em cantores. Método Participaram 30 cantores, sem queixas vocais ou alterações laríngeas, divididos em grupo controle (GC) e experimental (GE). O GC realizou a TVSL por cinco minutos. O GE foi submetido à nebulização de 3 ml de solução salina seguido da TVSL por cinco minutos. Foram realizadas autoavaliação vocal, análise acústica e avaliação perceptivoauditiva nos momentos pré (PréTVSL) e pós (PTVSL) no GC e no momento pré (PréHTVSL), pós hidratação (PH) e pós hidratação+TVSL (PHTVSL) no GE. Na autoavaliação foram avaliados: qualidade, estabilidade, rouquidão e intensidade vocal. Os parâmetros acústicos analisados foram Frequência Fundamental; Jitter%; Shimmer%, Noise-to-harmonic Ratio e Cepstral Peak Prominence-Smoothed (CPPs). A avaliação perceptivoauditiva foi realizada por uma fonoaudióloga experiente. Resultados Na comparação dos resultados da autoavaliação, entre os grupos, observou-se melhora da percepção de estabilidade e intensidade vocal no PTVSL (GC) em relação ao PH (GE). Na comparação entre os momentos do GE houve diferença estatística na sensação de intensidade vocal, apontando melhor resultado para PHTVSL. Não houve diferença estatística entre os grupos investigados na avaliação perceptivoauditiva e na análise acústica. Conclusão A hidratação laríngea de superfície não potencializa o efeito da TVSL em cantores em condição natural de hidratação com uso de 3ml de nebulização. Para os profissionais da voz com grande demanda vocal, a hidratação de superfície pode ser introduzida durante a utilização da voz, para manutenção da qualidade vocal, sem perda de sua qualidade.


ABSTRACT Purpose To analyze the immediate effect of laryngeal surface hydration associated with the performance of Tongue Trills (TT) on singers. Methods Thirty singers without vocal complaints or laryngeal alterations divided into control (CG) and experimental (EG) groups. The CG performed the TT for five minutes. The EG was submitted a nebulization with 3 ml of saline solution followed by TT for five minutes. Voice self-assessment, acoustic analysis and perceptual assessment were performed at Pre (Pre TT) and post (PTT) moments in CG and pre (Pre TT), post hydration (PH) and post hydration + TT (PHTT) in GE. In the self-assessment were evaluated quality, stability, vocal intensity and hoarseness. There were extract the values of the Fundamental frequency; Jitter%; Shimmer%, Noise-to-harmonic Ratio e Cepstral Peak Prominence-Smoothed (CPPs) in the acoustic analyze. The perceptual evaluation was performed by an experienced speech therapist. Results Comparing the results of self-assessment between groups showed improvement in the perception of stability and vocal intensity in the PTT (CG) in relation to PH (EG). Comparison between the EG moments showed a statistical difference in the vocal intensity perception, indicating a better results for PHTT. There was no statistical difference between the groups investigated in the perceptual assessments and acoustic analysis. Conclusion Surface laryngeal hydration does not potentiate the effect of TT on naturally hydrated singers with 3ml nebulization. For voice professionals with high vocal demand, surface hydration can be introduced during voice use to maintain vocal quality.

ABSTRACT

The aim of this study was to explore the effect of hsa_circ_0002162 on regulating cell proliferation, apoptosis, and invasion, and investigate its potential target microRNA (miRNA) in tongue squamous cell carcinoma (TSCC). Hsa_circ_0002162 expression was detected in human TSCC cell lines and human oral keratinocytes (HOK) cell line. Cell proliferation, apoptosis, invasion, and candidate target miRNA expressions were detected in hsa_circ_0002162 knockdown-treated CAL-27 cells and hsa_circ_0002162 overexpression-treated SCC-9 cells. In the rescue experiment, miR-33a-5p knockdown plasmid was transfected into hsa_circ_0002162 knockdown-treated CAL-27 cells, while miR-33a-5p overexpression plasmid was transfected into hsa_circ_0002162 overexpression-treated SCC-9 cells. Subsequently, cell proliferation, apoptosis, and invasion were detected, and then luciferase reporter assay was performed. Hsa_circ_0002162 expression was increased in human TSCC cell lines SCC-9, CAL-27, HSC-4, and SCC-25 compared with HOK. In CAL-27 cells, hsa_circ_0002162 knockdown inhibited cell proliferation and invasion and promoted apoptosis. In SCC-9 cells, hsa_circ_0002162 overexpression enhanced cell proliferation and invasion and suppressed apoptosis. Furthermore, a negative regulation of hsa_circ_0002162 on miR-33a-5p (but not miR-302b-5p and miR-545-5p) was observed. In the rescue experiment, miR-33a-5p knockdown increased cell proliferation and invasion, and decreased apoptosis in hsa_circ_0002162 knockdown-treated CAL-27 cells, whereas miR-33a-5p overexpression decreased cell proliferation and invasion, but increased apoptosis in hsa_circ_0002162 overexpression-treated SCC-9 cells. The luciferase reporter assay showed the direct binding of hsa_circ_0002162 to miR-33a-5p. In conclusion, hsa_circ_0002162 had an important role in malignant progression of TSCC through targeting miR-33a-5p.

ABSTRACT

Abstract Background Malocclusions are highly prevalent in childhood and adolescence, being considered a public health problem worldwide, in addition to be considered an important predictor in the tongue position and speech disorders. Objective Evaluate the association of malocclusions with tongue position and speech distortion in mixed-dentition schoolchildren from the south of Brazil. Methodology This cross-sectional study was performed using a database of an epidemiological survey realized in the southern of Brazil, in 2015, for evaluating the dental and myofunctional condition of the mixed-dentition from 7-13 years' schoolchildren. The outcome variables were tongue position and speech distortion, evaluated by a trained and calibrated examiner. Characteristics regarding sociodemographic and oral health measures (Angle's classification of the malocclusion, overjet, overbite, posterior crossbite and respiratory mode) were also assessed. Poisson regression models with adjusted robust variance were used to evaluate the association among predictors variables in the outcomes. Results are presented as prevalence ratio (PR) and 95% confidence interval (95% CI). Results A total of 547 children were evaluated. Schoolchildren who presented anterior open bite (PR 2.36 95%CI 1.59-3.49) and having oral/oral-nasal breathing (RP 2.51 95%CI 1.70-3.71) are more likely to have altered position of the tongue. Both deep bite and being male represent protection factors for the abnormal tongue position. Regarding speech distortion, deep overbite presents a protective relationship to speech distortion (PR 0.41; 95%CI 0.24-0.71), whereas schoolchildren with posterior crossbite were more likely to present this problem (PR 1.77; 95%CI 1.09-2.88). Conclusion Anterior open bite and posterior crossbite were the malocclusions related to speech distortion and/or altered tongue position. Oral/oral-nasal breathing was also related to myofunctional changes. Deep bite malocclusion was a protective factor for both speech problems and altered tongue position when compared to a normal overbite.

ABSTRACT

La iniciativa internacional para la estandarización de la dieta de disfagia (IDDSI) clasifica la viscosidad de los líquidos por niveles y determina metodologías específicas para evaluar cada consistencia. Con todo, la iniciativa no determina las medidas específicas de espesante requeridas para obtener cada nivel de viscosidad y sugiere hacer adaptaciones de acuerdo con las condiciones particulares de aplicación. Este estudio desarrolló una propuesta para la preparación de viscosidades mediante pruebas experimentales en las que se controló rigurosamente la cantidad de espesante y agua haciendo uso de instrumentos de mezclado de fácil acceso en entornos clínicos (vasos plásticos, jarra de agua, baja lenguas para integrar los elementos y cronómetro para considerar el tiempo de fraguado). Posterior a ello, cada nivel de viscosidad obtenido fue evaluado con el test de flujo propuesto por las IDDSI. Como resultado, este estudio especifica las cantidades necesarias de agua y espesante para conseguir viscosidad en bebidas de 0-4. Los hallazgos presentados, tienen en cuenta factores influyentes como la ubicación geográfica, temperatura y altitud. Se espera que esta propuesta incida en las dinámicas de evaluación de la deglución en el área clínica colombiana de forma que esta sea más precisa y eficaz. Finalmente, es pertinente realizar futuras investigaciones que determinen medidas específicas de espesante para lograr cambios en la viscosidad de líquidos diferentes al agua e igualmente necesario, replicar esta propuesta con otros espesantes de más fácil acceso para los usuarios y que tengan en cuenta otros aspectos como la palatabilidad


The International Dysphagia Diet Standardisation Initiative (IDDSI) classifies the viscosity of liquids by levels and determines specific methods to evaluate each consistency. However, the initiative does not determine the specific measures of thickener required to obtain each level of viscosity and suggests making adaptations according to the particular conditions of application. This study developed a proposal for the preparation of viscosities through experimental tests in which the amount of thickener and water was rigorously controlled using mixing instruments that were easily accessible in clinical settings (plastic cups, pitcher of water, tongue depressors to integrate the elements and timer to consider setting time). After that, each level of viscosity obtained was evaluated with the flow test proposed by the IDDSI. As a result, this study specifies the required amounts of water and thickener to achieve drinks viscosities 0-4. The findings presented take into account influencing factors such as geographic location, temperature and altitude. It is expected that this proposal will affect the dynamics of swallowing assessment in the Colombian clinical area so that it is more precise and effective. Finally, it is pertinent to carry out future investigations that determine specific measures of thickener to achieve changes in the viscosity of liquids other than water and it is equally necessary to replicate this proposal with other thickeners that are easier for users to access and that take into account other aspects such as palatability.

ABSTRACT

RESUMO As próteses bucomaxilofaciais (PBMF) têm como objetivo a reabilitação oral de pacientes com mutilações decorrentes de cirurgias de câncer de boca. Como parte dessa reabilitação oral, a terapia fonoaudiológica associada ao biofeedback ultrassonográfico da língua possibilita melhor precisão da produção de fala. O presente estudo teve por objetivo caracterizar a produção de fala de um indivíduo com histórico de múltiplas cirurgias oncológicas que levaram à glossectomia total, com auxílio de um dispositivo individualizado de acrílico, idealizado a partir da parceria Odonto-Fonoaudiologia da instituição e confeccionado por especialista em PBMF e terapia fonoaudiológica, utilizando o biofeedback visual com ultrassonografia. O indivíduo era homem, 45 anos, professor aposentado com histórico de carcinoma epidermóide de língua com episódios de recidiva. Como tratamento oncológico, foram realizadas diversas cirurgias associadas à radioterapia, ao longo de sete anos. O tratamento oncológico culminou com a glossectomia total e instalação de osteorradionecrose de mandíbula. O tratamento desta sequela da radioterapia também exigiu múltiplas abordagens cirúrgicas, com perda de grande parte da mandíbula, levando ao severo comprometimento das funções de deglutição e fala. Durante o atendimento multiprofissional da equipe Odonto-Fonoaudiologia de um hospital universitário, foi idealizada a confecção de um dispositivo individualizado de acrílico, objetivando melhorar a inteligibilidade da fala do paciente. Tal dispositivo foi confeccionado por dentista especialista em PBMF e ajustado em conjunto com a equipe de Fonoaudiologia. Com o dispositivo de acrílico adaptado, o indivíduo iniciou a terapia fonoaudiológica associada ao biofeedback, por meio da ultrassonografia de língua, com o objetivo de promover o refinamento da produção de fala dos fones fricativos [s] e [∫]. Ao comparar a avaliação pré-terapia e pós-terapia, foi possível identificar, após a análise das falas por juízes, melhora quanto à Porcentagem de Consoantes Corretas, de moderadamente severa para levemente moderada, bem como a inteligibilidade de fala, de insuficiente para regular. O dispositivo individualizado com a terapia fonoaudiológica associada ao biofeedback produziram resultados de fala satisfatórios, considerando-se a gravidade do caso e o elevado grau de mutilação do paciente.


ABSTRACT The oral maxillofacial prostheses (PBMF) aim the oral rehabilitation of patients with mutilations resulting from oral cancer surgery. The oral rehabilitation was composed of speech therapy associated with ultrasound biofeedback of the tongue, which allows better precision in speech production. The present study aims to characterize the speech production of an individual with a history of multiple oncological surgeries with total glossectomy with the aid of an individualized acrylic device, designed based on the partnership between Dentistry and Speech Therapy and made by a prosthetic dentist, undergoing therapy and speech therapy with visual biofeedback by ultrasound. The individual is a 45-year-old man, retired teacher with a history of tongue squamous cell carcinoma with episodes of recurrence. The cancer treatment was performed by several surgeries associated with radiotherapy over seven years. This treatment resulted in total glossectomy and the presence of osteoradionecrosis (ORN) of the mandible. The sequel to radiotherapy also required multiple surgical approaches with loss of a large part of the jaw, causing severe impairment of swallowing and speech functions. During the multidisciplinary care provided by the Dentistry and Speech Therapy team at a university hospital. The creation of an individualized acrylic device was conceived, aiming to improve the speech intelligibility of the patient. This device was made by a prosthetic dentist and adjusted together with the Speech Therapy team. With the adapted acrylic device, the individual started speech therapy associated with biofeedback by means of tongue ultrasound with the aim of promoting the refinement of the speech production of the fricative headphones [s] and [∫]. When comparing the pre-therapy and post-therapy assessment (after the analysis of the speeches by judges) it was possible to identify an improvement in the Percentage of Consonants Correct (PCC) from moderately-severe to slightly-moderate, as well as speech intelligibility from insufficient to regulate. The individualized device with speech therapy associated with biofeedback produced satisfactory speech results, considering the severity of the case and the high degree of mutilation of the patient.

ABSTRACT

ABSTRACT Objective: To evaluate and systematize tongue color-related manifestations among patients with PCR-confirmed COVID-19 infection. Material and Methods: This retrospective study included analysis of tongue images obtained from patients with PCR-confirmed COVID-19 infection. Evaluation of coronavirus disease severity (mild, moderate, severe, critical) was provided, considering clinical symptomatology and results of laboratorial and instrumental diagnostic methods. Each picture was analyzed considering the parameters of color of the tongue and color of the tongue plaque by two dental specialists. Cochran-Armitage test for trend was used to evaluate associations between the tongue color and tongue plaque color, and coronavirus disease severity. Results: The most prevalent tongue colors were pale pink, red and dark red (burgundy color). A total of 64.29% of patients with mild disease demonstrated pale pink color of the tongue. Patients with moderate coronavirus disease were characterized with the adverse trend: 62.35% of them presented with red-colored tongue, while in 37.64% of cases, the tongue was pale pink. Severe COVID-19 patients, almost in 90% of the cases, had either red or burgundy color of the tongue. Conclusion: SARS-COV-2 infection is not manifested by tongue-targeted or tongue-specific signs and features; however, coronavirus disease itself provokes changes within the tongue color and tongue plaque color similar to those registered during other internal pathologies.

ABSTRACT

Escalas e questionários podem participar do rastreio, diagnóstico e acompanhamento de condições médicas, por isso são importantes na prática clínica. Para que sejam utilizados em um país diferente do de origem, estes devem passar por um processo de adaptação cultural, visando garantir a validade e confiabilidade iguais ao instrumento original. Embora não exista um modelo padrão-ouro a ser seguido, quatro passos são essenciais e recomendados para este processo: tradução, tradução reversa, revisão por um comitê de juízes e pré-teste. O objetivo do estudo foi identificar quais são os processos reconhecidos cientificamente realizados para a validação de instrumentos de pesquisa direcionados à língua portuguesa do Brasil. Os artigos foram identificados na base de dados PubMed, através dos descritores validation studies AND translation AND adaptation AND cross-cultural AND Brazil. Foram selecionados 16 artigos para esta revisão, publicados entre 2017 e 2019. As metodologias de validação foram variadas, sendo que cada trabalho apresentou elementos metodológicos complementares e particulares às populações estudadas. A compilação destas metodologias permitiu evidenciar os pontos comuns que podem ser seguidos na elaboração de futuras pesquisas, buscando a construção de um roteiro unificado que permita sua utilização universal na validação e adaptação transcultural de instrumentos de pesquisa.

ABSTRACT

La Tomografía Computarizada continúa como la técnica diagnóstica de elección para la estadificación inicial y seguimiento de los pacientes con cáncer de lengua. Objetivo: Determinar las características imagenológicas por Tomografía Computarizada Simple y Contratada a casos con carcinoma epidermoide de lengua. Materiales y métodos: Se realizó una investigación preliminar, descriptiva, prospectiva en una muestra de 21 casos. Resultados: La edad predominante estuvo entre los 60-65 años, con antecedentes de tabaquismo y/o alcoholismo (63,4%). La mayor cantidad de casos presentaron tumores en la base (n=11; 52,38 %) y borde derecho (n=5; 23,81%) de la lengua, con tomas ganglionares submentoniana (n=9; 42,86%), submandibular (n=6; 28,57%) y yugular medio (n=4; 19,05%). Todos los tumores primarios (n=21; 100%) presentaron realce tras el contraste endovenoso, de ellos 19 (90,48%) mostraron patrón de captación intensa y homogénea. Mayoritariamente no se observó infiltración vascular (n=20; 95,24%), ni infiltración del tejido subcutáneo (n=20; 95,24%) o infiltración ósea (n= 8; 38,10 %). La infiltración glandular y el cruce de línea media se precisaron en 8 casos (38,10 %) respectivamente. Conclusiones: Los casos con tumores de lengua predominan en hombres mayores de 60 años con factores de riesgo como el tabaquismo y/o alcoholismo. La tomografía contrastada posibilita redefinir los indicadores imagenológicos en la arquitectura tumoral y ganglionar para el diagnóstico del cáncer de lengua. Se recomienda la inclusión de la maniobra dinámica en la evaluación de las dimensiones, extensión de la lesión primaria y la valoración del engrosamiento de las encías como un predictor de futuras metástasis óseas.

Computed Tomography continues as the diagnostic technique of choice for initial staging and follow-up of tongue cancer patients. Objective: To determine the imaging characteristics by Simple and Contracted Computed Tomography to cases with epidermoid tongue carcinoma. Materials and methods: A preliminary, descriptive, prospective investigation was conducted in a sample of 21 cases. Results: The predominant age was between 60-65 years, with a history of smoking and/or alcoholism (63.4%). The largest number of cases had tumors at the base (n=11; 52.38%) and right edge (no=5; 23.81%) of the tongue, with submentonian ganglion sockets (n=9; 42.86%), submandibular (n=6; 28.57%) and middle jugular (n-4; 19.05%). All primary tumors (n=21; 100%) highlighted after the endovenous contrast, of which 19 (90.48%) showed an intense and homogeneous uptake pattern. Mostly no vascular infiltration was observed (n=20; 95.24%), nor infiltration of subcutaneous tissue (n=20; 95.24%) bone infiltration (no=8; 38.10%). Glandular infiltration and midline crossing were specified in 8 cases (38.10%) respectively. Conclusions: Cases with tongue tumors predominate in men over 60 years of age with risk factors such as smoking and/or alcoholism. Proven tomography makes it possible to redefine imaging indicators in tumor architecture and ganglion for the diagnosis of tongue cancer. It is recommended to include dynamic manoeuvre in the evaluation of dimensions, extent of primary injury and assessment of gum thickening as a predictor of future bone metastases. (AU)
