RESUMO

El tratamiento con implantes dentales hoy en día es un procedimiento clínico de rutina que permite rehabilitar a los pacientes con prótesis fijas. En este caso presentamos un tratamiento complejo de implantación inmediata del sector anterior con pérdida parcial de la cortical vestibular en el que se realizó una regeneración ósea guiada y provisionalización en un tiempo quirúrgico en un paciente con patología renal. Complementamos el estudio con una revisión de la efectividad de las técnicas utilizadas y las posibles respuestas celular asociadas a la patología renal.


Treatment with dental implants nowadays is a routine clinical procedure that allows patient rehabilitation with fixed prostheses. In this case we present a complex treatment of immediate implantation of the anterior sector with partial loss of the vestibular cortex, in which guided bone regeneration and provisionalization was performed in surgical time in a patient with kidney pathology. The study was complemented with a review of the effectiveness of the techniques used and the possible cellular responses associated with kidney pathology.

RESUMO

Resumen El carcinoma sarcomatoide primario hepático es un tumor agresivo que representa el 0.4-0.7% de todas las neoplasias primarias hepáticas. Se asocia a hepa topatía por virus hepatotropos, es más prevalente en la población asiática y en su histología se evidencian componentes de carcinoma y sarcoma. No posee carac terísticas clínicas ni imagenológicas patognomónicas y su diagnóstico se realiza en base a los hallazgos de la anatomía patológica e inmunohistoquímica. La cirugía en estadio localizado representa la única modalidad terapéutica con impacto en la sobrevida. Reportamos el caso de una paciente de 72 años, coreana, con an tecedentes de hepatopatía crónica por virus B, a quien se le diagnosticó un carcinoma sarcomatoide hepático primario con metástasis ósea y ganglionares.


Abstract Primary hepatic sarcomatoid carcinoma is a very ag gressive tumor, representing 0.4-0.7% of all primary he patic neoplasms. The disease is associated with liver dis ease due to hepatotropic viruses and is more prevalent in Asians. Histology shows sarcomatous and carcinoma components. It does not have pathognomonic clinical or imaging characteristics and its diagnosis is based on the pathological and immunohistochemistry findings. Surgery could prolong survival in localized stages. We report the case of a 72-year-old Korean patient with a history of chronic liver disease due to B virus, who was diagnosed with primary hepatic sarcomatoid carcinoma with bone and lymph node metastases.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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)

RESUMO

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.

Se trata de un estudio transversal, descriptivo y observacional de 542 pacientes, de los cuales el 62.7% (340) pertenecen al sexo femenino y 37.3% (202) al masculino; la edad se distribuyó en un rango de dos a 85 años con una media de 28 años y fue categorizada en cinco grupos etarios: 2 a 12, 13 a 18, 19 a 35, 36 a 69 y > 70 años. En este estudio participaron una especialista en patología bucal, un especialista en odontopediatría y una pasante de la licenciatura de estomatología quien fungió como ayudante de investigación. Fueron identificadas 13 variantes de la normalidad y 52 lesiones en total, mismas que son reportadas por zona anatómica, por rangos de edad y por sexo. El número de condiciones y lesiones diagnosticadas por paciente varió de una a cinco en 87.27% y en el restante 12.73% no se detectó ninguna. Las variantes de la normalidad o condiciones más frecuentes fueron lengua fisurada con 12.17%, apéndice mucoso en frenillo vestibular con 11.25% y gránulos de Fordyce con 10.88%. Las lesiones más prevalentes por zona anatómica fueron: nevo intradérmico con 2.39% en labio externo superior e inferior; queilitis simple con 11.43% en la interfase de piel y mucosa de los labios (borde bermellón); úlcera traumática con 3.87% en mucosa labial; absceso de origen dental con 1.42 en encía; frenillo con inserción baja 1.84% en frenillos; úlcera traumática con 5.53% en mucosa bucal; candidiasis atrófica crónica con 5.53% en paladar; amígdalas hipertróficas con 8.11% en zona amigdalina; lengua pilosa con 1.66% en lengua; úlcera traumática con 3.69% en piso de boca; granuloma piógeno con 0.18% en proceso alveolar; y por último, hipertrofia de glándulas salivales labiales con 0.55% asociadas a presencia de aparatología ortodóntica. Finalmente se llevó a cabo una prueba de χ2 de Pearson para establecer correlación entre variables dependientes e independientes, encontrando significancia estadística de p < 0.000 entre lesiones de lengua y condición sistémica y edad en relación a lesiones de lengua, paladar y labios con p < 0.000 (AU)


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)

RESUMO

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)

RESUMO

Introducción. El melanoma es la proliferación maligna de melanocitos asociado a un comportamiento agresivo. El objetivo de este estudio fue determinar las variables histológicas del melanoma cutáneo. 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.

RESUMO

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.

RESUMO

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.

RESUMO

ABSTRACT BACKGROUND: There is a lack of studies evaluating the oral health of traditional indigenous communities in Brazil. OBJECTIVES: Thus, the objective of this study was to describe the oral health characteristics of the indigenous Fulni-ô ethnic group in Northeast Brazil. DESIGN AND SETTING: A cross-sectional observational investigation was conducted within the Project on Atherosclerosis among Indigenous Populations. METHODS: This study included participants of both sexes from the Fulni-ô ethnic group. The participants included in this investigation underwent a comprehensive oral health evaluation by a registered and experienced dentist to assess oral health and identify potentially malignant oral lesions. Participants with suspicious lesions were referred for biopsy. Shapiro-Wilk, Mann-Whitney, and Student's t-tests were used, and measures of central tendency and dispersion were described. Statistical significance was 5%. RESULTS: A total of 104 individuals were included in this study. The prevalence of the use of tobacco derivatives was 94.0%, with similarities between sexes. The prevalence of oral changes in this study population was 84.4%. Fifty-one individuals who underwent oral reassessment were referred for oral lesion biopsy. CONCLUSIONS: This study demonstrated a high prevalence of oral alterations in the Fulni-ô population. Histopathological analyses indicated the presence of mild oral epithelial dysplasia in five cases.

RESUMO

ABSTRACT Purpose: To assess Meibomian gland dysfunction using meibography in patients with xeroderma pigmentosum and correlate with ocular surface changes. Methods: This cross-sectional study evaluated patients with xeroderma pigmentosum. All patients underwent a comprehensive and standardized interview. The best-corrected visual acuity of each eye was determined. Detailed ophthalmic examination was conducted, including biomicroscopy examination of the ocular surface, Schirmer test type I, and meibography, and fundus examination was also performed when possible. Meibomian gland dysfunction was assessed by non-contact meibography using Oculus Keratograph® 5M (OCULUS Inc., Arlington, WA, USA). Saliva samples were collected using the Oragene DNA Self-collection kit (DNA Genotek Inc., Ottawa, Canada), and DNA was extracted as recommended by the manufacturer. Factors associated with abnormal meiboscores were assessed using generalized estimating equation models. Results: A total of 42 participants were enrolled, and 27 patients underwent meibography. The meiboscore was abnormal in the upper eyelid in 8 (29.6%) patients and in the lower eyelid in 17 (62.9%). The likelihood of having abnormal meiboscores in the lower eyelid was 16.3 times greater than that in the upper eyelid. In the final multivariate model, age (p=0.001), mutation profile (p=0.006), and presence of ocular surface malignant tumor (OSMT) (p=0.014) remained significant for abnormal meiboscores. For a 1-year increase in age, the likelihood of abnormal meiboscores increased by 12%. Eyes with OSMT were 58.8 times more likely to have abnormal meiboscores than eyes without ocular surface malignant tumor. Conclusion: In the final model, age, xeroderma pigmentosum profile, previous cancer, and clinical alterations on the eyelid correlated with a meiboscore of ≥2. Meibomian gland dysfunction was common in patients with xeroderma pigmentosum, mainly in the lower eyelid. The severity of Meibomian gland dysfunction increases with age and is associated with severe eyelid changes.

RESUMO

ABSTRACT Purpose: To evaluate the choroidal vascular alterations and effect of surgical treatment in the setting of idiopathic epiretinal membranes. Methods: The structure of the choroid was studied in 33 patients with unilateral idiopathic epiretinal membrane using optical coherence tomography with enhanced depth imaging and optical coherence tomography angiography. Eyes with epiretinal membrane underwent 25-gauge vitrectomy with epiretinal membrane and internal limiting membrane peeling. The choroidal vascularity index, Haller layer/choroidal thickness ratio, and choriocapillaris flow density were used to evaluate changes in choroidal structure after surgery and compare with the healthy fellow eyes. Results: The choroidal vascularity index and Haller layer/choroidal thickness ratio of the eyes with epiretinal membrane were higher than those of the fellow eyes at baseline (p=0.009 and p=0.04, respectively) and decreased postoperatively compared with preoperative values (p=0.009 and p=0.001, respectively). The choriocapillaris flow of eyes with epiretinal membrane was lower than that of the fellow eyes at baseline (p=0.001) and increased after surgery compared with the preoperative value (p=0.04). The choroidal vascularity index, Haller layer/choroidal thickness ratio, and choriocapillaris flow values of the healthy fellow eyes were comparable at baseline and final visit. In eyes with epiretinal membrane, the final choroidal vascularity index correlated with the final choriocapillaris flow (r=-0.749, p=0.008) in the multivariate analysis. Conclusion: Idiopathic epiretinal membrane appears to affect the choroidal structure with increased choroidal vascularity index and Haller layer/choroidal thickness ratio and decreased choriocapillaris flow. These macrovascular (choroidal vascularity index and Haller layer/choroidal thickness) and microvascular (choriocapillaris flow) alterations appear to be relieved by surgical treatment of the epiretinal membranes.

RESUMO

ABSTRACT Echinococcosis is a parasitic disease caused by infection with tiny tapeworms of the genus Echinococcus. Echinococcosis is classified as either cystic echinococcosis or alveolar echinococcosis. The common form is a zoonosis from goats and sheep that tends to cause liver lesions. The larval stage of Echinococcus multilocularis causes alveolar echinococcosis/alveolar hydatid disease. It is a zoonosis with field mice and tundra voles as intermediate and wild carnivores like foxes and wolves as definitive hosts. This zoonosis is highly uncommon compared to the other form known as cystic echinococcosis but poses a great human threat if untreated. We report the case of a young man who was working in the Kashmir Valley, North India, and presented with jaundice and right upper quadrant abdominal pain. Computed tomography revealed a large solid-cystic intrahepatic lesion measuring 125x118x123 mm, suggestive of a malignant tumor with central necrosis. A liver biopsy showed necrosis with PAS-positive membranes morphologically consistent with echinococcosis. Alveolar echinococcosis can present as a solid-cystic mass in the liver and can simulate metastatic malignancy.

RESUMO

Abstract Objective: To identify the most prevalent oral lesions based on reports from a pathology institute's reports and associations between malignant and oral potentially malignant disorders with patient's demographic variables and the anatomical location. Material and Methods: All 1,298 histopathological reports of oral lesions recorded in the database were reviewed. Demographic variables, anatomical location of the lesion, histopathological diagnosis of the lesions, and their biological behavior were analyzed. Results: Regarding the biological behavior of the identified lesions, benign lesions were predominant (70%), followed by lesions of undetermined behavior (14.3%), malignant lesions (14.2%), absence of histological alteration (1.2%), and finally, oral potentially malignant disorders (0.5%). The anatomical locations of the most prevalent oral lesions potentially malignant disorders and malignant were in the following structures of the oral cavity: gums, buccal mucosa, floor of the mouth and hard palate (p=49.2%), and tongue (p=48.7%). Conclusion: The probability of malignant and premalignant lesions was higher among males (PR= 4.21; 95% CI 2.08-6.22), the increase in age (PR = 1.06; 95% CI 1.05-1.08), and in the tongue region (PR = 5.48; 95% CI 1.67; 17.92). Identification of malignant and potentially malignant oral conditions is higher in older men and in tongue specimens.
