RESUMEN
Introducción: La esclerosis lateral amiotrófica (ELA) es la forma más común de enfermedad degenerativa de motoneurona en la edad adulta y es considerada una enfermedad terminal. Por lo mismo, el accionar del fonoaudiólogo debe considerar el respeto a los principios bioéticos básicos para garantizar una asistencia adecuada. Objetivo: Conocer aquellas consideraciones bioéticas relacionadas al manejo y estudio de personas con ELA para luego brindar una aproximación hacia el quehacer fonoaudiológico. Método: Se efectuó una búsqueda bibliográfica en las bases de datos PubMed, Scopus y SciELO. Se filtraron artículos publicados desde 2000 hasta junio de 2023 y fueron seleccionados aquellos que abordaban algún componente bioético en población con ELA. Resultados: Aspectos relacionados al uso del consentimiento informado y a la toma de decisiones compartidas destacaron como elementos esenciales para apoyar la autonomía de las personas. Conclusión: Una correcta comunicación y una toma de decisiones compartida son claves para respetar la autonomía de las personas. A su vez, la estandarización de procedimientos mediante la investigación clínica permitirá aportar al cumplimiento de los principios bioéticos de beneficencia y no maleficencia, indispensables para la práctica profesional.
Introduction: Amyotrophic lateral sclerosis (ALS) is the most common form of degenerative motor neuron disease in adulthood and is considered a terminal disease. For this reason, the actions of the speech therapist must consider respect for basic bioethical principles to guarantee adequate assistance. Objective: To know those bioethical considerations related to the management and study of people with ALS to then provide an approach to speech therapy. Methodology: A bibliographic search was carried out in the PubMed, Scopus, and SciELO databases. Articles published from 2000 to June 2023 were filtered and those that addressed a bioethical component in the population with ALS were selected. Results: Aspects related to the use of informed consent and shared decision-making stood out as essential elements to support people's autonomy. Conclusion: Proper communication and shared decision-making are key to respecting people's autonomy. In turn, the standardization of procedures through clinical research will contribute to compliance with the bioethical principles of beneficence and non-maleficence, essential for professional practice.
RESUMEN
In a context where different protocols for recommended practices in clinical voice assessment exist, while there are gaps in the literature regarding the evidence base supporting assessment procedures and measures, clinicians from regions where a strong community holding expertise in clinical and scientific voice practices lack can struggle to confidently develop their voice assessment practices. In an effort to improve voice assessment practices and strengthen professional identity among speech-language pathologists in Quebec, Canada, a community of practice (CoP) was established, with the aim of promoting knowledge sharing, implementing change in clinical practice, and improving professional identity. Thirty-nine participants took part in the CoP activities conducted over a four-month period, including virtual meetings and in-person workshops. Participants had a high rate of attendance (> 74% participation rate in virtual meetings), and were highly satisfied with their participation and intended to remain involved after the project's end. Statistically significant changes in voice assessment practices were observed post-CoP, regarding probability of performing assessments (p < .001), and perceived importance of assessment for evaluative purposes (p <.001), as well as improvements in assessment specific confidence, specifically for procedure of auditory-perceptual assessment (p < .001) and purpose of aerodynamic assessment (p = .05). Moreover, there was an increase in professional identity post-CoP (p < .001) and participants felt they made significant learnings. The present study highlighted the need to involve SLPs in future research to identify assessments that are relevant to the specific evaluative objectives of SLPs working with voice, and suggests CoPs are an efficient tool for that purpose.
En un contexto en el que existen diferentes protocolos para las prácticas recomendadas en la evaluación vocal clínica, y en el que se presentan vacíos en la literatura respecto a la base de evidencia que respalda los procedimientos y medidas de evaluación, los profesionales de regiones donde no hay una comunidad sólida con experiencia en prácticas vocales clínicas y científicas pueden enfrentar dificultades para desarrollar con confianza sus prácticas de evaluación vocal. Con el propósito de mejorar las prácticas de evaluación vocal y fortalecer la identidad profesional entre los logopedas de Quebec, Canadá, se estableció una comunidad de práctica (CdP). Esta tenía como objetivo fomentar el intercambio de conocimientos, implementar cambios en la práctica clínica y mejorar la identidad profesional. Un total de treinta y nueve participantes se involucraron en las actividades de la CdP, llevadas a cabo durante un período de cuatro meses, que incluyeron reuniones virtuales y talleres presenciales. Los participantes tuvieron una alta tasa de asistencia (> 74% de participación en las reuniones virtuales) y expresaron un alto grado de satisfacción con su participación, manifestando su intención de continuar involucrados después de la finalización del proyecto. Se observaron cambios estadísticamente significativos en las prácticas de evaluación vocal posterior a la CdP, en lo que respecta a la probabilidad de llevar a cabo evaluaciones (p < .001) y la percepción de la importancia de la evaluación con fines evaluativos (p < .001), así como mejoras en la confianza específica en la evaluación, particularmente en el procedimiento de evaluación auditivo-perceptual (p < .001) y el propósito de la evaluación aerodinámica (p = .05). Además, se registró un aumento en la identidad profesional posterior a la CdP (p < .001) y los participantes sintieron que obtuvieron aprendizajes significativos. El presente estudio destacó la necesidad de involucrar a los logopedas en investigaciones futuras, para identificar evaluaciones pertinentes a los objetivos evaluativos específicos de los logopedas que trabajan con la voz, y sugiere que las CdP son una herramienta eficiente con ese propósito.
RESUMEN
La displasia dentinaria tipo I (DD-I) corresponde a una alteración dentinaria de heterogeneidad genética y penetrancia completa, en donde se presenta un defecto en el desarrollo de las raíces de los dientes tanto temporales como definitivos. Clínicamente se observan dientes con extrema movilidad junto con antecedentes de exfoliación prematura o espontánea. Los defectos estructurales de los tejidos dentarios, tales como DD-I; implican un desafío ya que son pocos los casos documentados en la literatura que hablan de esta condición. Además implican un tratamiento multidisciplinario y altamente invasivo. El objetivo de este artículo es presentar dos casos de DD-I, enfatizando en su tratamiento y características histopatológicas.
Dentin Dysplasia Type I (DD-I) consists of a pathological dentinary alteration with genetic heterogeneity that results in a defectuous development of dental roots both in primary and secondary dentition. Clinically we can appreciate teeth with extreme pathological mobility and premature or spontaneous exfoliation. Alterations within normal dental structure, such as DD-I imply a challenge for the common practitioner, because of the scarce number of case reports with in the scientific literature regarding this condition and also, because of the need for a highly invasive and multidisciplinary approach they require. The aim of this article is to present two DD-I cases, emphasizing on their treatment and histopathological features.
RESUMEN
Introdução: os lipomas são as neoplasias benignas de origem mesenquimal mais comum, podendo acometer diversas partes do corpo, sendo a região maxilofacial, de fato, uma das menos frequentes. Clinicamente, manifestam-se como aumentos de volume de crescimento lento e circunscrito, de base séssil ou pediculada, superfície lisa e consistência macia e coloração amarelada. Os sítios intra-orais mais acometidos são a mucosa jugal e o vestíbulo bucal.Dentre suas variantes microscópicas mais comuns, estão o fibrolipoma, composto de um componente fibroso. No entanto, tais variações não afetam o prognóstico do seu tratamento, que deve ser realizado através da excisão conservadora da lesão. OBJETIVO: O presente trabalho tem como objetivo relatar um caso atípico de lipoma intra-oral. DESCRIÇÃO DO CASO: Paciente do sexo feminino, 67 anos, apresentou-se com aumento de volume em região de fundo de vestíbulo mandibular com evolução de, aproximadamente, 10 meses, indolor, com queixas de dificuldade no posicionamento da prótese dentária inferior. O diagnóstico inicial foi de lipoma, confirmado por análise anatomopatológica através de biópsia excisional da peça. Considerações finais: O tratamento de lipomas intra-orais preconizado pela literatura é a excisão local, obtida por meio da biópsia excisional, sendo uma solução eficaz e de baixa morbidade ao paciente(AU)
Introduction: lipomas are the most common benign neoplasms of mesenchymal origin, which can affect different parts of the body, with the maxillofacial region, in fact, one of the least frequent. Clinically, they manifest as slow-growing, circumscribed swellings, with a sessile or pedunculated base, smooth surface, soft consistency and yellowish color. The most affected intraoral sites are the buccal mucosa and the buccal vestibule. Among its most common microscopic variants are the fibrolipoma, composed of a fibrous component. However, such variations do not affect the prognosis of its treatment, which must be carried out through conservative excision of the lesion. OBJECTIVE: This study aims to report an atypical case of intraoral lipoma. CASE DESCRIPTION: A 67-yearold female patient presented with swelling in the bottom region of the mandibular vestibule with an evolution of approximately 10 months, painless, with complaints of difficulty in positioning the lower dental prosthesis. The initial diagnosis was lipoma, confirmed by anatomopathological analysis through excisional biopsy of the specimen. Final considerations: The treatment of intraoral lipomas recommended by the literature is local excision, obtained through excisional biopsy, being an effective solution with low morbidity for the patient(AU)

El conocimiento de la patología oral, y su correcto diagnóstico es fundamental en Odontología, puesto que un diagnóstico tardío, particularmente en casos de lesiones premalignas o malignas, pueden conducir a serias consecuencias para el paciente. El objetivo de este trabajo fue establecer la congruencia diagnóstica clínica - histopatológica de lesiones en cavidad oral en pacientes que asistieron a la Facultad de Odontología, Universidad de Costa Rica, y a quienes se les realizó biopsia de la lesión, durante el período 2016-2019. El estudio fue descriptivo y retrospectivo, basado en datos de reportes histopatológicos en la población mencionada, por presentar alguna lesión, de tejidos blandos o duros, en cavidad oral. La muestra estadística fue por conveniencia, no probabilística y no aleatoria. Las técnicas estadísticas utilizadas fueron descriptivas para el análisis de la información, el cual se basó en la distribución de frecuencias y cruce de variables. El procesamiento estadístico de los datos se diseñó en una base de datos creada en Excel. La muestra comprendió 160 reportes histopatológicos de los cuales se excluyeron 14. La edad promedio de los pacientes fue 42 años (rango 2 - 78 años). La proporción hombre: mujer correspondió 1:1.4, predominado el sexo femenino en 58,9 %. La congruencia del diagnóstico histopatológico con el diagnóstico clínico correspondió a 55,8 %. La congruencia de los diagnósticos demuestra el conocimiento del profesional en identificar la lesión clínicamente de forma correcta, lo que permite actuar en el momento preciso y confirmar la impresión clínica diagnóstica de una patología mediante el estudio histopatológico, el cual es el estándar oro. El problema radica en aquellos casos en que hay discrepancia diagnóstica, pues exige conocer los factores responsables de esta discrepancia, exige la búsqueda de soluciones y exige reforzar y redireccionar la formación académica del profesional y de los estudiantes para reconocer y describir estas lesiones.
Knowledge of oral pathology and its correct diagnosis is fundamental in Dentistry, since a late diagnosis, particularly in cases of premalignant or malignant lesions, can lead to serious consequences for the patient. The objective of this study was to establish the clinical- histopathological diagnostic consistency of lesions in the oral cavity in patients who attended the Faculty of Dentistry, Universidad de Costa Rica, and who underwent a biopsy of the lesion, during the period 2016-2019. The study was descriptive and retrospective, based on data from histopathological reports in the mentioned population, due to presenting some lesion, soft or hard tissue, in the oral cavity. The statistical sample was for convenience, non- probabilistic nor random. The statistical techniques used were descriptive for the analysis of the information, which was based on frequency distribution and crossing of variables. The statistical processing of the data was designed in a database created in Excel. The sample collects 160 histopathological reports, of which 14 were excluded. The average age of the patients was 42 years (range between 2 - 78 years old).The male:female ratio corresponded to 1:1.4, with a predominance of the female sex at 58.9 %.The congruence of the histopathological diagnosis with the clinical diagnosis corresponded to 55.8 %. Diagnostic consistency demonstrates knowledge of the professional in correctly identifying the lesion clinically, which allows acting at the precise moment and confirming the diagnostic clinical impression of the pathology via histopathological study which is the gold standard. The problem lies in those cases in which there is a diagnostic discrepancy, since it requires having knowledge of the underlying factors and therefore, requires searching for solutions, reinforcing and redirecting the academic training of professionals and students to recognize and describe these lesions.

The purpose of this study is to analyze the prevalence of variants of normality and pathology in the mucosa of the oral cavity by anatomical area in a controlled population in a university undergraduate stomatological clinic in the state of Mexico. This is a cross-sectional, descriptive and observational study of 542 patients, of which 62.7% (340) belonged to the female gender and 37.3% (202) to the male gender, the age was distributed in a range of two to 85 years with a mean of 28 years and was categorized in five age groups: 2 to 12, 13 to 18, 19 to 35, 36 to 69 and > 70 years. A specialist in oral pathology, a specialist in pediatric dentistry and an intern in stomatology who served as a research assistant participated in this study. Thirteen variants of normality and 52 lesions in total were identified and reported by anatomical area, age range and gender. The number of conditions and lesions diagnosed per patient ranged from one to five in 87.27% and none were detected in 12.73% of the population studied. The most frequent variants of normality or conditions were fissured tongue with 12.17%, mucous appendage in the vestibular frenulum with 11.25% and Fordyce granules with 10.88%. The most prevalent lesions by anatomical area were: intradermal nevus with 2.39% in upper and lower external lip; simple cheilitis with 11.43% in the interphase interface of skin and mucosa of the lips (vermilion border); traumatic ulcer with 3.87% in labial mucosa; abscess of dental origin with 1.42 in gingiva; frenulum with low insertion 1.84% in frenulum; traumatic ulcer with 5. 53% in buccal mucosa; chronic atrophic candidiasis with 5.53% in palate; hypertrophic tonsils with 8.11% in tonsillar area; hairy tongue with 1.66% in tongue; traumatic ulcer with 3.69% in floor of mouth; pyogenic granuloma with 0.18% in alveolar process and finally; hypertrophy of labial salivary glands with 0.55% associated with the presence of orthodontic appliances. Finally, a Pearson's χ2 test was carried out to establish correlation between dependent and independent variables, finding statistical significance of p < 0.000 between tongue lesions and systemic condition and age in relation to tongue, palate and lip lesions with a p < 0.000 (AU)

Introducción: el metotrexato se usa ampliamente para el tratamiento de una variedad de enfermedades neoplásicas y autoinmunes. Sin embargo, como todo fármaco, su eficacia viene marcada por cierto grado de toxicidad debido a la farmacocinética del medicamento. El metotrexato se creó como un fármaco anticancerígeno; sin embargo, se ha convertido en el tratamiento de elección contra la artritis reumatoide. Principalmente, el metotrexato causa inflamación de las mucosas epiteliales. La mayoría de los efectos secundarios del metotrexato se pueden detectar de forma temprana y son reversibles. La mucositis del tracto alimentario es el principal efecto secundario de la quimioterapia contra el cáncer. Se le conoce colectivamente como lesión de la mucosa inducida por quimioterapia, afecta todo el canal alimentario desde la boca hasta el ano, ocasionando la mucositis oral y la mucositis intestinal. Material y métodos: se buscaron casos clínicos en los que se reporte mucositis causada por metotrexato en tratamiento de artritis reumatoide. Se empleó un diagrama de flujo, PRISMA modificado para la búsqueda de artículos. Finalmente, se cotejó que los casos clínicos cumplieran con los fundamentos de la CARE guide, para manejar una correcta estructura y bajo riesgo a sesgo. Conclusiones: una correcta anamnesis y exploración clínica oral es lo más importante de la medicina oral. Es relevante indagar sobre las enfermedades que presentan los pacientes, así como la historia de medicamentos que se administren, especialmente en pacientes mayores, con mayores padecimientos de enfermedades sistémicas (AU)
Introduction: methotrexate is widely used for the treatment of a variety of neoplastic and autoimmune diseases. However, like all drugs its efficacy is marked by a certain degree of toxicity due to the pharmacokinetics of the drug. Methotrexate was developed as an anticancer drug, however, it has become the treatment of choice for rheumatoid arthritis. Methotrexate primarily causes inflammation of the epithelial mucous membranes. Most of the side effects of methotrexate can be detected early and are reversible. Mucositis of the alimentary tract is the main side effect of cancer chemotherapy. It is collectively known as chemotherapy-induced mucosal injury, affecting the entire alimentary canal from the mouth to the anus, where oral mucositis and intestinal mucositis are both common. Material and methods: we searched for clinical cases reporting mucositis caused by methotrexate in the treatment of rheumatoid arthritis, using a modified PRISMA flowchart to search for articles. Finally, the clinical cases were checked for compliance with the fundamentals of the CARE guide, in order to manage a correct approach to oral medicine. It is important to inquire about the diseases the patients present, as well as the history of medications administered, especially in older patients, with more systemic disease conditions, structure, and low risk of bias. Conclusion: a correct anamnesis and oral clinical examination is the most important aspect of oral medicine. It is important to inquire about the diseases that the patients present, as well as the history of medications that are administered, especially in older patients with major systemic diseases (AU)

Métodos. Estudio observacional retrospectivo, transversal descriptivo, realizado con reportes de patologías de pacientes con diagnóstico de melanoma cutáneo en un laboratorio de patología en Cali, Colombia, entre 2016-2021. Se incluyeron las variables edad, sexo, localización, subtipo, espesor de Breslow, ulceración, márgenes, mitosis, invasión linfovascular, neurotrofismo, regresión tumoral, nivel de Clark e infiltración tumoral por linfocitos. Resultados. Se obtuvieron 106 reportes y fueron excluidos 54 por duplicación. Se incluyeron 52 registros, la media de edad fue de 61 años, con una mayor frecuencia de mujeres (55,8 %). De los 33 casos donde se especificó el subtipo histológico, el más frecuente fue el de extensión superficial (66,6 %), seguido del acral lentiginoso (18,1 %) y nodular con (15,2 %). La localización más frecuente fue en extremidades (61,5 %). El espesor de Breslow más común fue IV (34,6 %) y el nivel de Clark más frecuente fue IV (34,6 %). La ulceración estuvo en el 40,4 %. El subtipo nodular fue el de presentación más agresiva, donde el 100 % presentaron espesor de Breslow IV. Conclusiones. El subtipo de melanoma más común en nuestra población fue el de extensión superficial; el segundo en frecuencia fue el subtipo acral lentiginoso, que se localizó siempre en extremidades. Más del 50 % de los melanomas tenían espesor de Breslow mayor o igual a III, lo que impacta en el pronóstico.
Background. Melanoma is the malignant proliferation of melanocytes associated with aggressive behavior. The objective of this study was to determine the histological variables of cutaneous melanoma. Methods. Observational, cross-sectional, descriptive, retrospective study carried out with reports of pathologies with a diagnosis of cutaneous melanoma in a pathology laboratory in Cali between 2016-2021. The variables were age, sex, location, subtype, Breslow thickness, ulceration, margins, mitosis, lymphovascular invasion, neurotropism, tumoral regression, Clark level and tumor infiltration by lymphocytes. Results. One hundred and six reports were obtained and 54 were excluded due to duplication. A descriptive analysis was made on the 52 records that were included, the mean age was 61 years, with a higher frequency in women with 55.8%. Of the 33 cases where the histological subtype was specified, the most frequent was superficial extension with 66.6%, followed by acral lentiginous with 18.1% and nodular with 15.2%. The most frequent location was in the extremities (61.5%); the most common Breslow was IV (34.6%), and the most frequent Clark was IV (34.6%). Ulceration was in 40.4%. The nodular subtype was the most aggressive presentation where 100% presented Breslow IV. Conclusions. The most common subtype of melanoma was that of superficial extension. In our population, the second most frequent was the acral lentiginous subtype, which was always located on the extremities. More than 50% of the melanomas had Breslow greater than or equal to III, which affects the prognosis.

Introducción. Los teratomas son neoplasias que surgen a partir de células germinales pluripotenciales y derivan de dos o más capas de células. Se clasifican en tumores maduros, que contienen tejidos bien diferenciados, o inmaduros, que contienen estructuras inmaduras y embrionarias. Su localización más frecuente son las gónadas; la ubicación mesentérica es infrecuente y se han descrito aproximadamente 40 casos en la literatura mundial. Dentro del abordaje diagnóstico y terapéutico, se emplea la tomografía computarizada y la resonancia magnética nuclear para caracterizar la lesión, evaluar la extensión intraabdominal y la relación con otras estructuras. El diagnóstico debe confirmarse mediante el examen histopatológico. Caso clínico. Paciente femenina de 56 años, con antecedente de carcinoma ductal infiltrante de mama izquierda en remisión, en estudios de seguimiento con hallazgo incidental en tomografía de abdomen de lesión abdominopélvica dependiente del mesenterio, contornos lisos y nivel grasa-líquido. Estudios de extensión con marcadores tumorales negativos. Resultados. Por la alta sospecha clínica e imagenológica de teratoma, fue llevada a resección quirúrgica de la lesión. El examen histopatológico confirmó el diagnóstico de teratoma quístico maduro del mesenterio. Conclusión. El teratoma mesentérico es una entidad clínica rara, que debe ser considerado como uno de los diagnósticos diferenciales de una masa abdominal con efecto compresivo. El diagnóstico se basa principalmente en el examen clínico y los hallazgos imagenológicos. La escisión quirúrgica temprana es el pilar del tratamiento; el abordaje laparoscópico o abierto depende de las características clínicas y la experiencia del cirujano.
Background. Teratomas are neoplasms that arise from pluripotent germ cells, derived from two or more layers of germ cells. They are classified as mature tumors (cystic or solid), which contain well-differentiated tissues, or as immature tumors, which contain immature and embryonic structures. Its most frequent location is the female and male gonads; the mesenteric location is rare and approximately 40 cases have been described in the world literature. Within the diagnostic and therapeutic approach, computed tomography and magnetic resonance imaging are used to characterize the lesion, assess intra-abdominal extension and the relationship with other structures. The diagnosis must be confirmed by histopathological examination. Clinical case. A 56-year-old female patient with a history of infiltrating ductal carcinoma of the left breast in remission. In follow-up studies, incidental abdominal tomography finding of an abdominopelvic lesion dependent on the mesentery at the level of the mesogastrium, smooth contours with fat-liquid level. Extension studies with negative tumor markers. Results. Due to high clinical and imaging suspicion of teratoma, the patient was taken to resection of the lesion. Histopathological examination confirmed the diagnosis of mature cystic teratoma of the mesentery. Conclusion. Mesenteric teratoma is a rare clinical entity and is considered one of the differential diagnoses of an abdominal mass with a compressive effect. Diagnosis is mainly based on clinical examination and imaging findings. Early surgical excision is the mainstay of treatment; laparoscopic or open approach depends on the clinical characteristics and the experience of the surgeon.

Abstract Several topics related to the oral cavity are briefly addressed in this article, from anatomical variations that, when recognized, avoid unnecessary investigations, to diseases that affect exclusively the mouth, mucocutaneous diseases, as well as oral manifestations of systemic diseases. A complete clinical examination comprises the examination of the mouth, and this approach facilitates clinical practice, shortening the path to diagnosis in the outpatient clinic as well as with in-hospital patients. The objective of this article is to encourage the examination of the oral cavity as a useful tool in medical practice, helping to recognize diseases in this location.
RESUMEN
Objective@#To explore the clinical manifestations, histopathological characteristics, diagnosis, treatment, and prognosis of simultaneous unilateral primary tumors of different pathological types in the parotid gland.@*Methods@#A case of simultaneous unilateral primary parotid gland tumors, i.e., adenolymphoma and basal cell adenoma, was reviewed and analyzed in combination with the literature.@*Results@#The patient discovered a lump in the right parotid gland area one month prior to presentation, and a tumor was palpated in the shallow lobe of the right parotid gland before surgery. According to MR images, the initial diagnoses were tumors of the shallow and deep lobes of the right parotid gland. The tumors of the deep and shallow lobes were excised with part of the gland, and the facial nerves were dissected under general anesthesia. Postoperative pathology revealed an adenolymphoma in the shallow lobe of the right parotid gland and a basal cell adenoma with cystic transformation in the deep lobe. The surgical effect was good, with no complications, and there was no recurrence after 1 year of follow-up. A review of the relevant literature showed that multiple primary tumors of the parotid gland can manifest as the simultaneous presence of two or more types of tumors on both sides or on one side, and the disease is mainly treated with surgery.@*Conclusion@#Multiple unilateral primary parotid gland tumors are rare. Imaging examinations need to be combined with clinical evaluations to prevent missed diagnoses. Surgery is the first treatment option, and patients with benign tumors have a good prognosis.
RESUMEN
Introdução: a hanseníase apresenta potencial incapacitante secundário às reações hansênicas. Existe considerável número de indivíduos com episódios recorrentes de reação durante o tratamento. Objetivo: identificar características clínicas e histopatológicas que diferenciem pacientes com reação hansênica ou não. Método: estudo prospectivo de julho/2015 a dezembro/2016, com avaliação de indivíduos com diagnóstico novo de hanseníase atendidos no serviço de dermatologia do Complexo Hospitalar Clementino Fraga, na cidade de João Pessoa, Paraíba, Brasil. Os sujeitos foram classificados segundo os critérios de Ridley-Jopling/Madrid e por classificação operacional. Realizaram exame histopatológico no momento do diagnóstico e após 12 meses, e reavaliados após 6 e 12 meses do diagnóstico. Resultados: o grupo sem reação apresentou maior número de lesões com nítida delimitação. Observou-se predomínio das formas multibacilares entre indivíduos com reação. Quanto ao grau de incapacidade, o grupo com reação apresentou maior número de indivíduos com grau de incapacidade maior que zero. No grupo sem reação, encontrou-se menor frequência de fatores predisponentes. Notou-se correlação positiva do índice baciloscópico de biópsia cutânea com a ocorrência de reações. Discussão: a ausência de delimitação periférica das lesões pode se correlacionar com o surgimento de reação hansênica. O predomínio de reação entre os indivíduos que apresentavam grau de incapacidade maior que zero sugere associação de deficiência física e doença multibacilar. A ausência de fatores predisponentes aponta menor risco de reação hansênica. Observou-se correlação positiva do índice baciloscópico da biópsia com a ocorrência das reações. Conclusão: a significativa prevalência de reações graves enfatizam a importância do estudo contínuo da hanseníase e a necessidade de identificar precocemente as características clínicas sugestivas de reações hansênicas.(AU)
Introduction: leprosy reactions have the potential to cause disabilities. Many individuals experience recurrent episodes of reaction during treatment. Objective:to identify clinical and histopathological characteristics that differentiate patients with leprosy reactions from those without leprosy reactions. Method: this is a prospective study conducted from July 2015 to December 2016, evaluating individuals newly diagnosed with leprosy and treated at the dermatology service of the Clementino Fraga Hospital Complex in João Pessoa, Paraíba, Brazil. The subjects were classified according to the Ridley-Jopling/Madrid criteria and operational classification. They underwent a histopathological examination at the time of diagnosis and 12 months later, and were reassessed 6 and 12 months after the diagnosis. Results: the group without a reaction had a greater number of lesions with clear delimitation. Individuals with a reaction showed a predominance of multibacillary forms. The group with a reaction had a greater number of individuals with a degree of disability greater than zero. A positive correlation was observed between the bacilloscopic index and the occurrence of reactions. Discussion: the lack of clear boundaries around the lesions may be linked to the onset of a leprosy reaction. The higher incidence of reactions in individuals with some degree of physical disability indicates a correlation between disability and multibacillary disease. Additionally, a positive correlation was found between the bacilloscopic index of the biopsy and the occurrence of reactions. Conclusion: the high incidence of severe reactions underscores the need for ongoing studies on leprosy and the identification of early clinical characteristics that suggest leprosy reactions.(AU)

Abstract This study aimed to evaluate the effect of atmospheric plasma application on the inactivation of fungi on the surface of Erythrina velutina seeds and on isolated fungal colonies. Two experiments were conducted using a completely randomized design. First, plasma was applied to the surface of the seeds using helium gas and atmospheric plasma for 3, 6, and 9 min in addition to the control (untreated seeds), constituting seven treatments with five repetitions each. In the second experiment, Petri dishes containing the inoculum of different fungi were treated with atmospheric air plasma for 3, 6, and 9 min (Air-3, Air-6, and Air-9) and were compared with untreated fungi in Petri dishes without treatment (control), totaling four treatments and five repetitions each. We found that the application of atmospheric air plasma to E. velutina seeds for 9 min had an antimicrobial effect on the fungi Aspergillus niger, Aspergillus flavus, Fusarium sp., Brachysporium sp., and Rhizopus sp. The formation of fungal colonies isolated from E. velutina seeds was also inhibited by 3 min of exposure to atmospheric air plasma, except for A. niger, whose inhibition occurred after 6 min of exposure to atmospheric plasma.
Resumo Este trabalho teve como objetivo avaliar o efeito da aplicação de plasma atmosférico na inativação de fungos na superfície de sementes de Erythrina velutina e em colônias fúngicas isoladas. Dois experimentos foram realizados em delineamento inteiramente casualizado: no primeiro, o plasma foi aplicado na superfície das sementes usando gás hélio e plasma atmosférico por três, seis e nove minutos, além do controle (sementes sem tratamento), constituindo sete tratamentos com cinco repetições cada; no segundo experimento, placas de Petri contendo o inóculo de diferentes fungos foram tratadas com plasma atmosférico por três, seis e nove minutos (Air-3, Air-6 e Air-9) e comparadas com fungos não tratados em placas de Petri sem tratamento (controle), totalizando quatro tratamentos e cinco repetições cada. Descobrimos que a aplicação de plasma atmosférico nas sementes de E. velutina por nove minutos teve efeito antimicrobiano sobre os fungos Aspergillus niger, Aspergillus flavus, Fusarium sp., Brachysporium sp. e Rhizopus sp. A formação de colônias fúngicas isoladas de sementes de E. velutina também foi inibida por três minutos de exposição à aplicação de plasma atmosférico, exceto para A. niger, cuja inibição ocorreu a partir de 6 minutos de exposição à aplicação de plasma atmosférico.

RESUMO Objetivo Criar um checklist da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) a partir de categorias relevantes para o desenvolvimento de fala e linguagem, segundo a percepção de pais e fonoaudiólogos. Método Realizou-se aplicação piloto e pesquisa. Na pesquisa participaram 100 pais de pré-escolares, com desenvolvimento típico de linguagem/cognição e 57 fonoaudiólogos especialistas em linguagem. Elaborou-se questionário com 199 categorias da CIF dos componentes de funções do corpo, atividades e participação e fatores ambientais. Cada categoria foi pontuada como: indispensável (2); importante (1) ou sem importância (0). Realizou-se a análise estatística (descritiva, soma, cluster/Método K-means e Mann-Whitney). Resultados Com a soma dos pontos (indispensável, importante e sem importância) e a quantidade de respostas indispensável, foram identificadas as categorias de maior relevância para cada grupo de respondentes, assim como o conjunto de categorias em comum (72 consideradas de maior influência). A listagem comum aos grupos contou com os três componentes: funções do corpo (30 categorias/40% do total), atividades e participação (35/49,29%) e fatores ambientais (sete/13,20%). Das categorias selecionadas, 58,33% apresentaram resultados estatisticamente significantes entre os grupos, quanto à relevância dada. Conclusão As categorias foram consideradas com pontuações distintas entre os grupos: as de funções do corpo foram mais pontuadas pelos fonoaudiólogos, enquanto as de fatores ambientais pelos pais. Assim, foi possível criar um checklist a partir da identificação das categorias mais relevantes para o desenvolvimento de fala e linguagem, em idade pré-escolar, contemplando os componentes funções do corpo, atividades e participação e fatores ambientais.
ABSTRACT Purpose Create a checklist of the International Classification of Functioning, Disability and Health (ICF) based on relevant categories for the development of speech and language, according to the perception of parents and speech therapists. Methods Pilot application and research were carried out. 100 parents of preschool children with typical language/cognition development and 57 language specialist speech therapists participated in the survey. A questionnaire was created with 199 ICF categories of body function components, activities and participation, and environmental factors. Each category was scored as: indispensable (2); important (1) or unimportant (0). Statistical analysis was performed (descriptive, sum, cluster/K-means and Mann-Whitney method). Results With the sum of the points (essential, important and unimportant) and the number of responses essential, the most relevant categories were identified for each group of respondents, as well as the set of categories in common (72 considered to have the greatest influence). The common list to the groups included the three components: body functions (30 categories/40% of the total), activities and participation (35/49.29%) and environmental factors (seven/13.20%). From the selected categories, 58.33% presented statistically significant results between the groups, regarding the relevance given. Conclusions The categories were considered with different scores between the groups: those of body functions were more scored by speech therapists, while those of environmental factors by parents. Thus, it was possible to create a checklist from the identification of the most relevant categories for the development of speech and language, in preschool age, contemplating the components of body functions, activities and participation and environmental factors.

RESUMEN
ABSTRACT Purpose: To longitudinally compare isolated structural parameters obtained using RTVue optical coherence tomography in patients with glaucoma and suspected glaucoma with stable visual fields. Methods: All patients were required to have a reliable SITA Standard 24-2 Humphrey Visual Field test. Visual field stability was defined as having <5 points with p<5% and/or having no points with p<1% and/or p<0.05% in the glaucoma progression analysis comparison graph. Furthermore, the glaucoma assessment strategy was used in optical coherence tomography. Results: The study included 75 eyes from 75 patients, 43 of which had glaucoma and 32 had suspected glaucoma. The mean visual field intervals were 29.57 ± 9.65 months between the first and third tests. No visual field parameter variations (mean deviation, pattern standard deviation, and visual field index) and no retinal nerve fiber layer or optic disk parameter variations between the first and third tests were observed (p>0.05 for all), and no retinal nerve fiber layer parameter variations throughout the study were observed, except for optic disk parameters presenting with cup volume changes (p=0.004). However, ganglion complex cells presented a progressively decreased average ganglion cell complex parameter, with a variability of -0.98% ± 3.71% (p=0.04) between the first and third tests. By contrast, the global loss volume progressively increased throughout the study, with a variability of 14.71% ± 44.52% (p=0.04) between the first and third tests. The inferior ganglion cell complex parameter was significantly decreased between the first and third tests (p=0.02). Conclusion: The present findings suggest that patients with glaucoma or suspected glaucoma with stable visual fields may present structural ganglion complex cell progression as assessed using RTVue optical coherence tomography.
RESUMO Objetivo: Comparar longitudinalmente os parâmetros estruturais isolados obtidos através da tomografia de coerência óptica RTVue em pacientes glaucomatosos e suspeitos de glaucoma com campos visuais estáveis. Métodos: Todos os incluídos deveriam ter Campimetria Computadorizada Humphrey Sita Standard 24-2 confiáveis. A estabilidade campimétrica foi definida se apresentassem menos de cinco pontos com p<5% e/ou nenhum ponto com p<1% e/ou p<0,05% no gráfico de comparação do Glaucoma Progression Analysis. Para a tomografia de coerência óptica, foi utilizado a estratégia de avaliação para glaucoma. Resultados: Foram incluídos 75 olhos de 75 pacientes: 43 com glaucoma e 32 suspeitos. A média dos intervalos do campo visual entre o 1o e 3o exame, foi de 29,57 ± 9,65 meses. Não houve variação para os parâmetros do campo visual (desvio médio, desvio padrão e índice da função visual) entre o primeiro e o último exame (p>0,05 para todos). Não houve variação dos parâmetros da camada de fibras nervosas da retina ao longo do estudo, enquanto que para os parâmetros do disco óptico, apenas cup volume apresentou mudança (p=0,004). Em relação à camada de células ganglionares da retina, notou-se uma redução progressiva na espessura média da Ganglionar Complex Cells com uma variabilidade entre o primeiro e último exame de -0,98 ± 3,71% (p=0,04). Quanto ao Global loss volume, houve um aumento progressivo ao longo do estudo com uma variabilidade entre o primeiro e último exame de 14,71 ± 44,52% (p=0,04). O parâmetro inferior do Ganglionar Complex Cells também reduziu significativamente entre o 1o e 3o exames (p=0,02). Os demais parâmetros da tomografia de coerência óptica RTVue se mantiveram estáveis entre o 1o e 3o exames. Conclusão: Os presentes achados sugerem que pacientes glaucomatosos ou com suspeita de glaucoma e com campos visuais estáveis, podem apresentar progressão estrutural na camada de células ganglionares da retina avaliada por meio da tomografia de coerência óptica RTVue.
RESUMEN
Abstract Background Cutaneous melanoma is a neoplasm with a high mortality rate and risk of metastases to distant organs. The Breslow micrometric measurement is considered the most important factor for evaluating prognosis and management, measured from the granular layer to the deepest portion of the neoplasm. Despite its widespread use, the Breslow thickness measurement has some inaccuracies, such as not considering variations in the thickness of the epidermis in different body locations or when there is ulceration. Objective To evaluate the applicability of a modified Breslow measurement, measured from the basal membrane instead of from the granular layer, in an attempt to predict sentinel lymph node examination outcome and survival of patients with melanoma. Methods A retrospective and cross-sectional analysis was carried out based on the evaluation of slides stained with hematoxylin & eosin from 275 cases of melanoma that underwent sentinel lymph node biopsy from 2008 to 2021 at a reference center in Brazil. Results Analysis of the Cox model to evaluate the impact of the Breslow measurement and the modified Breslow measurement on survival showed that both methods are statistically significant. Logistic regression revealed a significant association between both measurements and the presence of metastasis in sentinel lymph nodes. Conclusion Measuring melanoma depth from the basal membrane (modified Breslow measurement) is capable of predicting survival time and sentinel lymph node outcome, as well as the conventional Breslow measurement.
RESUMEN
Abstract Background Bullous pilomatricoma is a rare variant of pilomatricoma. As it has been published in sporadic case reports, a limited understanding of its clinicopathological characteristics restricts its effective diagnosis and treatment. Objectives This study aimed to analyze the clinicopathological and immunohistochemical characteristics of bullous pilomatricoma to better understand the bullous transformation of pilomatricoma. Methods The authors conducted a retrospective study of 12 patients with bullous pilomatricoma and compared their clinical, histopathological, and immunohistochemical data with those of patients with ordinary pilomatricoma. Results Bullous pilomatricoma showed no sex preference, with a mean onset age of 31.2 years. The common sites were the upper extremities and trunk. Bullous pilomatricoma had a shorter disease duration, a larger diameter, and a greater tendency to increase in size than those of ordinary pilomatricoma. Histopathologically, bullous pilomatricoma had a shorter duration, lesser calcification, more mitotic figures, and distinct dermal features from those of ordinary pilomatricoma. Immunohistochemically, the expression of Matrix Metalloprotease (MMP)-2, MMP-9, vascular endothelial growth factor receptor-3 (VEGFR-3), and VEGF-C was elevated. Study limitations The study was retrospective, and the sample size was small. Conclusion The distinctive features of bullous pilomatricoma potentially result from dermal changes associated with the release of angiogenic factors and proteolytic enzymes. This comprehensive analysis provides novel insights into the clinical features and pathogenesis of bullous pilomatricoma.
