Abstract Introduction Aural polyps are a misnomer. Any lesion can present as a mass in the external auditory canal. Aural polyps are proliferation of the granulation tissue due to long standing inflammatory process with associated otalgia and otorrhea. Objectives To document the clinicoradiological presentations, intraoperative findings, and histopathological diagnosis of aural polyp, correlating them. Methods In our study 81 patients underwent treatment for aural polyps in the department of Ear, Nose, and Throat (ENT) from April 1997 to April 2022. Results were tabulated, a simple descriptive analysis was done using the Statistical Package Social Sciences software, and the results obtained were represented as percentages and presented in tables. Results The majority (38) of the patients presenting with aural polyps were diagnosed with mucosal and squamous type of CSOM, and 22 with simple granulation polyps. There were also 5 patients with malignant otitis externa, 3 patients had glomus tumors, 2 patients with retained foreign bodies, and 3 patients with brain herniation. We also identified aberrant internal carotid artery, high jugular bulb, one patient had facial nerve neuroma, one patient had polyp from the tragus diagnosed with tuberculosis, one patient with keratosis obturans, and one with exostosis. Conclusion A thorough detailed examination and mastoid exploration with radiological and histopathological evaluation is mandatory for better defining the definitive treatment.

Resumen: El comercio electrónico del sector de la moda ha aumentado en los últimos años en Latinoamérica, especialmente a raíz de la pandemia, sin embargo, todavía existen problemas en la aceptación de este canal de compra. La presente investigación se centra en algunos factores que podrían influir en la intención de compra y tiene como objetivos comprobar cómo en ella influyen la confianza, los riesgos percibidos, los costos y la conveniencia. Para esto, se suministró un cuestionario a 223 estudiantes de cuatro universidades del Ecuador. Para el análisis de los datos obtenidos se desarrolló un modelo PLS-SEM, en el cual la confianza en el vendedor actúa como variable mediadora en la relación entre los otros tres factores y la intención de compra. Los resultados muestran que dicho modelo tiene un aceptable poder predictivo y explicativo. Asimismo, se comprueba que los riesgos, la conveniencia y la confianza afectan significativamente a la intención de compra, pero no los costos. Además, la confianza mediaría la relación entre las tres variables y la intención de compra en línea. Se concluye que el modelo propuesto puede servir de base para estudios similares y, a su vez, se considera que los resultados obtenidos pueden ser utilizados por las empresas en el sector de la moda que quieren vender a través de plataformas de e-Commerce para el desarrollo de estrategias de marketing.

Abstract: E-commerce in the fashion sector has increased in recent years in Latin America, especially in the wake of the pandemic, however, there are still issues in the acceptance of this shopping channel. The present research focuses on some factors that could influence purchase intention and aims to test how it is influenced by trust, perceived risks, costs and convenience. For this purpose, a questionnaire was given to 223 students from four universities in Ecuador. A PLS-SEM model was developed for the analysis of the data, in which trust in the seller has a mediating role in the relationship between the other three factors and purchase intention. Results show that this model has acceptable predictive and explanatory power. Likewise, it validates that risks, convenience and trust significantly affect intention, but not costs. In addition, trust would mediate the relationship between the other variables and online shopping intention. It is concluded that the proposed model can serve as a basis for similar studies, and, at the same time, it is considered that the results obtained can be used by business in the fashion sector that pursue to sell through e-commerce platforms for marketing strategies development.

Abstract: Passive Optical Networks (PONs) are essential in optical communications to meet the increasing demand for network capacity and connected users, ensuring reliable and adaptable connections for data transmissions. These networks also simplify infrastructures and efficiently utilize energy by eliminating the need for active devices. In this context, Ultra- Dense Wavelength Division Multiplexing (UDWDM) is one of the most prominent solutions for data transmission. This technology uses the narrow separation between channels from 25GHz and even as small as 6.25GHz to increase the transmission capacity. This document analyzes the performance of UDWDM considering the transmission of three simultaneous channels in a PON network for which three different scenarios have been considered for the analysis with the following parameters: i) transmission speed from 10 Gbps to 17 Gbps, ii) the distance from 10 km to 20 km and iii) the separation between channels of 15GHz, 20GHz, and 25GHz. The performance metrics for the analyzed scenario are the bit error rate and the eye diagram. To ensure the reception of the transmitted channel, an analysis of raised cosine and Gauss filters is also discussed. Including these filters allows for verifying whether their use enhances the performance of the channels compared to transmission without a filter. This is crucial for understanding how filters can optimize the quality and reliability of data transmission in a PON, which is of great importance in environments where high efficiency and connection quality are required.

Resumen: Las redes ópticas pasivas (PON) son esenciales en las comunicaciones ópticas para satisfacer la creciente demanda de capacidad de red y usuarios conectados, garantizando conexiones fiables y adaptables para la transmisión de datos. Estas redes también ofrecen un uso eficiente de la energía y la simplificación de las infraestructuras, eliminando la necesidad de dispositivos activos. En este contexto, la multiplexación por división de longitud de onda ultradensa (UDWDM) es una de las soluciones más destacadas para la transmisión de datos; esta tecnología aprovecha la estrecha separación entre canales a partir de 25GHz e incluso de tan solo 6,25GHz para aumentar la capacidad de transmisión. Este documento analiza el rendimiento de UDWDM considerando la transmisión de tres canales simultáneos en una red PON para la que se han considerado tres escenarios diferentes para el análisis con los siguientes parámetros: i) velocidad de transmisión de 10 Gbps a 17 Gbps; ii) la distancia de 10 km a 20 km; y iii) la separación entre canales de 15GHz, 20GHz, y 25GHz. Las métricas de rendimiento para el escenario analizado son la tasa de errores de bit y el diagrama de ojo. Para garantizar la recepción del canal transmitido, también se analiza la utilización de filtros coseno elevado y Gauss. La inclusión de estos filtros permite comprobar si su uso mejora el rendimiento de los canales en comparación con la transmisión sin filtro. Esto es crucial para entender cómo los filtros pueden optimizar la calidad y fiabilidad de la transmisión de datos en una PON, lo que es de gran importancia en entornos donde se requiere una alta eficiencia y calidad de conexión.

ABSTRACT Cholesteatoma of the External Auditory Canal (CCAE) is a rare pathology. Its diagnosis is fundamentally clinical, based on imaging studies and final anatomopathological confirmation. Some cases can be asymptomatic and other cases can present complications such as facial paralysis, middle ear involvement, etc. Its treatment is surgical with a series of techniques called canaloplasties, which aim to remove the cholesteatomatous tissue and create a self-evacuation mechanism. We present the description of a case of cholesteatoma of the auditory canal complicated with retroauricular abscess in a young patient with congenital stenosis, discuss the relevant aspects regarding the clinic, differential diagnoses, and therapeutic options in a review of the available literature.

RESUMEN El Colesteatoma del Conducto Auditivo Externo (CCAE) constituye una patología poco frecuente. Su diagnóstico es fundamentalmente clínico, se apoya en los estudios de imagen y confirmación final anatomopatológica. Algunos casos pueden ser asintomáticos y otros casos pueden presentar complicaciones como parálisis facial, afectación del oído medio, etc. Su tratamiento es quirúrgico con una serie de técnicas denominadas canaloplastias, las cuales tienen como objetivo retirar el tejido colesteatomatoso y crear un mecanismo de autoevacuación. Presentamos la descripción de un caso de colesteatoma del conducto auditivo complicado con absceso retroauricular en una paciente joven con estenosis congénita, discutimos los aspectos relevantes respecto a la clínica, diagnósticos diferenciales y opciones terapéuticas en una revisión de la literatura disponible.

Teachers can integrate this social platform to foster motivation and learning in students.

Resumen Este estudio tuvo como objetivo investigar el impacto de la combinación de cloruro de benzalconio (BAC) e hipocloruro de sodio (NaOCl) y su aplicación después del ácido etilendiaminotetraacético (EDTA) en procedimientos de irrigación del conducto radicular sobre la microdureza y el contenido mineral de la dentina. Las raíces distales de los terceros molares mandibulares se incluyeron en resina acrílica autopolimerizable y se seccionaron de coronal a apical, lo que dió como resultado cincuenta y cuatro secciones de raíz. Treinta secciones se sometieron a una evaluación de microdureza y veinticuatro secciones fueron elegidas al azar para el análisis mineral. La evaluación de la microdureza comprendió tres grupos: Grupo 1 (2,5% NaOCl), Grupo 2 (2,5% NaOCl con 0,084% BAC) y Grupo 3 (2,5% NaOCl con 0,084 BAC post-17% EDTA). Para cada grupo se midieron los valores de microdureza inicial y post- irrigación. Para el análisis mineral, las muestras se clasificaron en cuatro grupos: agua destilada, 2,5% NaOCl, 2,5% NaOCl con 0,084% BAC y 17% EDTA+2,5% NaOCl con 0,084% BAC. La espectroscopía fotoelectrónica de rayos X midió inmediatamente el contenido de minerales de magnesio, fósforo y calcio en las superficies de la dentina después de la irrigación. Los resultados indicaron una reducción significativa en la microdureza de la dentina radicular para todas las soluciones (p<0,05). Sin embargo, no se observó diferencia estadísticamente significativa en el porcentaje de reducción entre los grupos (p>0,05). El análisis XPS no reveló ninguna disparidad significativa en el contenido mineral de la superficie de la dentina entre los grupos (p>0,05). En conclusión, la adición de cloruro de benzalconio al hipocloruro de sodio, solo o después de EDTA, no indujo una alteración significativa en la microdureza o el contenido mineral de la dentina. Estos hallazgos contribuyen a una comprensión matizada de los protocolos de irrigación dental y sus efectos sobre las propiedades de la dentina durante los procedimientos de endodoncia.

Abstract This study aimed to investigate the impact of the combination of Benzalkonium chloride (BAC) and sodium hypochloride (NaOCl) and its application after ethylenediaminetetraacetic acid (EDTA) in root canal irrigation procedures on the microhardness and mineral content of dentin. Distal roots of mandibular third molars were embedded in auto-polymerizing acrylic resin, sectioned coronally to apically resulting in fifty-four root sections. Thirty sections underwent microhardness evaluation, and twenty-four sections were randomly chosen for mineral analysis. The microhardness assessment comprised three groups: Group 1 (2.5% NaOCl), Group 2 (2.5% NaOCl with 0.084% BAC), and Group 3 (2.5% NaOCl with 0.084 BAC post-17% EDTA). Initial and post-irrigation microhardness values were measured for each group. For mineral analysis, samples were categorized into four groups: distilled water, 2.5% NaOCl, 2.5% NaOCl with 0.084% BAC, and 17% EDTA+2.5% NaOCl with 0.084% BAC. X-ray photoelectron spectroscopy immediately measured magnesium, phosphorus, and calcium mineral contents on dentin surfaces post-irrigation. Results indicated a significant reduction in root dentin microhardness for all solutions (p<0.05). However, no statistically significant difference in the percentage of reduction was observed among the groups (p>0.05). XPS analysis revealed no significant disparity in dentin surface mineral content among the groups (p>0.05). In conclusion, the addition of Benzalkonium chloride to sodium hypochloride, either alone or after EDTA, did not induce a significant alteration in dentin microhardness or mineral content. These findings contribute to a nuanced understanding of dental irrigation protocols and their effects on dentin properties during endodontic procedures.

RESUMEN La competencia con arvenses es uno de los factores que limitan la producción del fríjol caupí en el mundo, causando pérdidas de hasta 90% del rendimiento y calidad de grano. El conocimiento del periodo crítico de competencia de las arvenses es importante para prevenir pérdidas significativas de grano y recursos en el proceso productivo. El objetivo fue determinar el periodo crítico de competencia de las arvenses en el cultivo de fríjol caupí, cultivar Missouri, en dos estaciones de siembra: seco (2022B) y lluvioso (2023A) del Caribe colombiano cálido y seco. Se utilizó el diseño bloques completos aleatorizados con ocho tratamientos y cuatro repeticiones. Los primeros cuatro tratamientos correspondieron al control manual de arvenses en los intervalos 0-10, 0-20, 0-30 y 0-50 días después de la emergencia (DDE), los segundos cuatro tratamientos correspondieron a la coexistencia cultivo-arvense, en los mismos intervalos. Se evaluó el rendimiento de grano del caupí, y masa seca, cobertura y composición de la comunidad de arvenses. El periodo crítico de competencia de las arvenses en el cultivo de fríjol caupí para la estación seca y lluviosa fue de 14-33 y 14-29 DDE. La reducción del rendimiento de grano fue de 65,2% en la estación seca y de 80,46%, en la estación lluviosa. Rottboellia cochinchinensis, fue la de mayor índice de ocurrencia con 30,3% y densidad de 90 individuos por m2; lo cual es importante para el manejo agronómico del cultivo en la subregión Caribe húmedo.

ABSTRACT Weed competition is one of the factors that limit cowpea production in the world, causing losses of up to 90% of grain yield and quality. Knowledge of the critical period of weed competition (CPC) is important to prevent significant losses of grain and resources in the production process. The objective was to determine the critical period of weed competition in the cultivation of cowpea beans, Missouri cultivar, in two sowing seasons: dry (2022B) and rainy (2023A) of warm dry Colombian Caribbean. The randomized complete block design was used with eight treatments and four repetitions. The first four treatments corresponded to manual control of weeds in the intervals 0-10, 0-20, 0-30 and 0-50 days after emergence (DAE), the second four treatments corresponded to the crop-weed coexistence, in the same intervals. Cowpea grain yield, dry mass, cover and weed community composition were evaluated. The critical period of competition of weeds in the cowpea crop for the dry and rainy seasons was 14-33 and 14-29 days after emergence, respectively. The reduction in grain yield was 65.2% in the dry season and 80.46% in the rainy season. Rottboellia cochinchinensis had the highest occurrence rate with 30.3% and a density of 90 individuals per m2; which is important for the agronomic management of the crop in the humid Caribbean subregion.

Abstract Television became the most important communication device in the 1990s, reaching all middle-class households and playing a relevant role in constructing shared social meaning. The aim of this article is to examine different dimensions and senses of humor in El palacio de la risa, a very popular television comedy show hosted by Antonio Gasalla between 1992 and 1996 -broadcast by ATC and Canal 13- in Argentina. We will focus on the sketches starred by the actors Alejandro Urdapilleta and Humberto Tortonese, who, together with Gasalla, introduced relevant innovations in the production of television humor. In the first section, we will analyze which elements of performing arts of the 1980s underground are used and put into play in this television comedy. Then, we will examine three dimensions that function as crucial material for the trio's humorous production: the critique of the Argentinean high classes, the tension between dominant and dissident sexualities, and the parodic mentions made about television itself. In terms of methodology, the work was based on an analysis of 30 sketches by the Urdapilleta-Gasalla-Tortonese trio, frequent subjects, aesthetic aspects, body gestures and discursive uses. In short, the work seeks to make a contribution to the knowledge of mass culture, as well as the parody and destabilization of the common sense upheld by television during the 1990s in Argentina.

Resumen La televisión se constituyó en el dispositivo comunicacional de mayor importancia en los años 1990, al llegar a todos los hogares de clase media y ocupar un rol preponderante en la elaboración de sentidos sociales compartidos. El objetivo de este artículo es indagar distintas dimensiones y sentidos del humor en El palacio de la risa, programa humorístico de gran relevancia conducido por Antonio Gasalla entre 1992 y 1996 y transmitido por ATC y Canal 13, en Argentina. Nos enfocaremos en los números protagonizados por los actores Alejandro Urdapilleta y Humberto Tortonese, quienes, junto a Gasalla, introducen importantes innovaciones en la producción humorística televisiva. En la primera sección, analizaremos qué elementos del teatro underground de los años 1980 son recuperados y puestos en juego en la propuesta televisiva. A continuación, se examinarán tres dimensiones que funcionan como materia prima para la producción humorística del trío: la crítica a las clases dominantes argentinas, la tensión entre sexualidades dominantes y disidentes, y las menciones paródicas realizadas sobre la propia televisión. En cuanto a la metodología, el trabajo fue realizado en base a un análisis de 30 sketches del trío Urdapilleta-Gasalla-Tortonese, registrando temas, aspectos estéticos, gestualidad corporal y usos discursivos. En suma, el trabajo realiza una contribución al conocimiento de la cultura de masas y las posibilidades paródicas y de desestabilización del sentido común de la televisión durante los años 1990 en Argentina.

Resumen El síndrome del martillo hipotenar es la trombosis de la arteria cubital en el canal de Guyon causada por traumatismos repetitivos. Se trata de un cuadro infrecuente que se diagnostica mediante la detallada valoración de los antecedentes y el examen físico, y se confirma con estudios vasculares. El manejo incluye desde tratamiento médico hasta cirugía reconstructiva. El objetivo de este artículo es brindar una breve reseña de esta enfermedad y presentar el caso de un paciente de 45 años, con parestesias y signos de hipoperfusión de los dedos 4.° y 5.° luego de múltiples traumatismos en la eminencia hipotenar. En la prueba de Allen, se detectó ausencia de vascularización de la arteria cubital, y la trombosis se confirmó mediante ecografía Doppler y angiotomografía. Se resecó el fragmento trombosado y se liberó el canal de Guyon. La evolución fue satisfactoria, no se observaron signos de isquemia y las parestesias mejoraron. Se realizó un seguimiento por 1 año.

Abstract Hypothenar hammer syndrome is a thrombosis of the ulnar artery in Guyon’s canal induced by repeated trauma. It is a rare disorder that can be diagnosed with an extensive medical history and physical examination, and confirmed by vascular studies. Management options include medical treatment and reconstructive surgery. The aim of this article is to provide a brief overview of this disorder and to discuss the case of a 45-year-old patient who developed paresthesias and signs of hypoperfusion of the fourth and fifth fingers following multiple injuries to the hypothenar eminence. The Allen test revealed the absence of vascularization in the ulnar artery, and thrombosis was verified by Doppler ultrasound and angiotomography. The thrombosed portion was excised, and Guyon’s canal was cleared. The evolution was satisfactory; no signs of ischemia were found, and paresthesias improved. Follow-up was performed for 1 year.

Introdução: O canal inguinal é região propensa a hérnias que podem ter indicação cirúrgica. Embora a videocirurgia possa ser menos agressiva, a identificação dos ramos nervosos é necessária para diminuir a incidência de inguinodinia que pode ocorrer mesmo com essa via minimamente invasiva. Objetivo: Revisar a incidência e os motivos da inguinodinia nos procedimentos cirúrgicos laparoscópicos na correção das hérnias inguinais. Método: Revisão sistemática, realizada nas bases de dados PubMed, BVS e Google Scholar no período de 2018 a 2024, incluindo artigos em português e inglês. De 1.758 artigos, 10 foram selecionados. Resultado: Os principais achados da pesquisa comprovaram que o reconhecimento e a devida identificação anatômica dos principais nervos da região inguinal durante a operação – ílio-hipogástrico, ilioinguinal e ramo genital do genitofemoral - são capazes de diminuir as chances de os pacientes desenvolverem dor crônica na região inguinal após hernioplastia. A perícia e experiência do cirurgião ao evitar trauma nos nervos locais garante qualidade de vida aos pacientes e reduz a exposição deles a eventuais novas intervenções subsequentes para tratamento de inguinodinia. Conclusão: A prevenção é a medida mais importante tratando-se de erradicar a inguinodinia. Dessa maneira, o profissional deve ter conhecimento suficiente da topografia mais frequente da passagem dos principais nervos e seus ramos para evitar lesões iatrogênicas.

Introduction: The inguinal canal is a region prone to hernias that may require surgery. Although videosurgery may be less aggressive, the identification of nerve branches is necessary to reduce the incidence of inguinodynia that can occur even with this minimally invasive route. Objective: To review the incidence and reasons for inguinodynia in laparoscopic surgical procedures for the correction of inguinal hernias. Method: Systematic review, carried out in the PubMed, BVS and Google Scholar databases from 2018 to 2024, including articles in Portuguese and English. From initial number of 1,758 articles 10 were selected. Result: The main findings of the research proved that the recognition and proper anatomical identification of the main nerves of the inguinal region during the operation - iliohypogastric, ilioinguinal and genital branch of the genitofemoral - are able to reduce the chances of patients developing chronic pain in the inguinal region after hernioplasty. The surgeon's expertise and experience in avoiding trauma to local nerves guarantees quality of life for patients and reduces their exposure to possible new subsequent interventions to treat inguinodynia. Conclusion: Prevention is the most important measure when it comes to eradicating inguinodynia. Therefore, the professional must have sufficient knowledge of the most frequent topography of the passage of the main nerves and their branches to avoid iatrogenic injuries

Abstract Introduction: Subtotal Petrosectomy (SPT) is an effective and definitive solution in cases of recurrent chronic otitis media. The expansion of its indications demonstrates its usefulness and safety in resolving various challenging otologic pathologies. Materials and Methods: A retrospective study of 25 patients (26 ears) who underwent SPT was conducted. Data regarding the indication, surgical procedures performed, complications, and clinical outcomes were collected. Results: Fourteen (n=14) patients with cholesteatomatous chronic otitis media (COM) were proposed for SPT due to recurrence. None of these patients (n=0) had useful hearing. Five (n=5) had facial palsy. The second most frequent indication (n=10) was COM associated with profound sensorineural hearing loss, and cochlear implantation was performed simultaneously in these cases. None (n=0) had facial palsy or disease recurrence. Other indications included tympanomastoid paraganglioma (n=1), anatomical factors in cochlear implant surgery (n=2), and intracochlear schwannoma (n=1). During the follow-up period (mean = 25 months), no signs or symptoms of recurrence were observed in these patients. Complications occurred in four cases, skin fistulization of SPT cavity (1), electrode array extrusion (1) and postoperative infection of the PST cavity (2). Conclusion: PST has proven to be a safe and effective surgical technique. PST with simultaneous cochlear implantation is a viable option for patients with COM. Surgical treatment with PST for COM should be considered when a poor audiological outcome is expected in a Canal Wall Down (CWD) mastoidectomy.

Resumo Introdução: A Petrosectomia Subtotal (PST) é uma solução eficaz e definitiva em várias patologias otológicas de difícil tratamento e pressupõe a exclusão do ouvido médio. Esta revela-se particularmente útil nestes casos, pois apresenta uma baixa taxa de complicações comparativamente a outras opções cirúrgicas. Material e Métodos: Estudo retrospetivo de 25 doentes (26 ouvidos) submetidos a PST. Foram recolhidos dados relativos à indicação, procedimentos cirúrgicos realizados, complicações e evolução clínica. Resultados: Catorze (n=14) doentes foram propostos para PST por recidiva de otite média crónica (OMC) colesteatomatosa. Nenhum destes doentes apresentava audição útil. Cinco (n=5) tinham parésia facial como complicação desta doença. A segunda indicação mais frequente (n=10) foi a surdez neurossensorial profunda com OMC não coleateatomatosa, a tímpano fechado. Em todos os casos foi realizada implantação coclear no mesmo tempo cirúrgico. Paraganglioma timpanomastoideu (n=1), fatores anatómicos na cirurgia de implantação coclear (n=2) e schwannoma intracoclear (n=1) constituíram as outras indicações. No follow up (x̅ = 25 meses) desses doentes, não foram observados sinais ou sintomas de recorrência. Foram registadas como complicações (n=4): fistulização da cavidade à pele (1), extrusão de elétrodo do Implante Coclear (1) e infeção pós-operatória da cavidade de PST (2). Conclusão: A PST demonstrou ser uma técnica cirúrgica segura e eficaz na doença otológica de difícil tratamento, mesmo quando associada com a implantação coclear no mesmo tempo cirúrgico. O tratamento cirúrgico com PST de uma OMC deve ser considerado quando se prevê um fraco resultado audiométrico numa mastoidectomia Canal Wall Down (CWD)

Abstract Radicular cysts result from an inflammatory process associated with teeth with pulp necrosis. The initial therapy is the endodontic treatment. However, if it fails, other treatment alternatives should be considered. Among them are some types of endodontic surgery that should be indicated according to the diagnosis of the tooth involved. Another technique for treating cysts is decompression, which can be used for the reduction or complete regression of the lesion and the preservation of adjacent noble structures. This case report, with a follow-up of two years, aims to present the therapy of a radicular cyst in close association with the mandibular canal through endodontic surgery and decompression of the lesion, as an alternative method to preserve the innervation of the inferior alveolar nerve.

Resumo O cisto radicular é um cisto de origem odontogénica causado por um processo inflamatório associado a dentes com diagnóstico de necrose pulpar. São os cistos mais comuns dos maxilares. A terapia inicial de eleição é o tratamento endodôntico do dente acometido. Contudo, em casos de insucesso, outras alternativas de tratamento devem ser consideradas. Entre as alternativas existem alguns tipos de cirurgia paraendodôntica que devem ser indicados de acordo com o diagnóstico do dente envolvido. Outra técnica para tratamento dos cistos é a descompressão, que pode ser utilizada para redução ou regressão completa da lesão e para conservação de estruturas nobres adjacentes. Esse relato de caso, com acompanhamento de dois anos, tem como objetivo apresentar a terapia de um cisto radicular em íntimo contato com o canal mandibular, por meio da cirurgia paraendodôntica e descompressão da lesão como método alternativo para preservação da inervação do nervo alveolar inferior.

Abstracy Achieving a favorable outcome after endodontic treatment depends on a clear understanding of tooth anatomy, identification of variations, and precise root canal location. Multi-rooted mandibular molars often deviate from the expected configuration, sometimes featuring additional roots, such as radix entomolaris (RE) and radix paramolaris (RP), posing challenges during treatment. Detecting these variations is challenging due to their proximity to the distal root, and overlooking them can lead to complications. This study presents three cases involving RE and RP and offers insights into their clinical management, encompassing thorough clinical assessment, diagnosis, and root canal treatment. At follow-up examinations, patients were asymptomatic with no radiographic evidence of persistent infection. Therefore, clinicians must be aware and informed about the potential presence of additional roots in mandibular molars during root canal procedures, as understanding and addressing anatomical variations like RE and RP is crucial for achieving favorable outcomes in root canal treatments.

Resumo Abordagem endodôntica de raízes adicionais dos molares mandibulares: relato de casos de radix entomolaris e radix paramolaris A obtenção de prognósticos favoráveis em tratamentos endodônticos está muito relacionada com um correto conhecimento da anatomia dentária. Molares mandibulares podem apresentar inúmeras variações da anatomia, sendo a presença de raízes adicionais uma possibilidade, como é o caso do radix entomolaris (RE) e do radix paramolaris (RP). A identificação destas variações pode tornar-se um desafio devido à sua proximidade com a raiz distal, o que pode levar a complicações no caso de serem ignoradas. O presente estudo apresenta três casos envolvendo RE e RP e descreve a sua abordagem clínica, que envolveu análise clínica, diagnóstico e tratamento endodôntico. Os controlos demonstraram que os pacientes estavam assintomáticos e sem sinais de infeção persistente. Os clínicos devem estar informados sobre a potencial presença de raízes adicionais durante os tratamentos endodônticos, uma vez que conhecer essas variações anatómicas, como o RE e RP, é crucial para alcançar um prognóstico mais favorável nos tratamentos.

Abstract A determination of how the amount of allotted feedlot living space influences both production indicators as well as carcass and meat quality traits obtained from Holstein steers was performed by forming two treatment groups, T14: 65 steers/pen (14 m2/head of space allowances) and T16: 57 steers/pen (16 m2/head of space allowances), with five replications each treatment. The average arrival weight 238 ± 0.74 kg. During the fattening period the cattle was feed twice a day with commercial diets. The steers were slaughtered after a 261-d period. At the moment of the first reimplant a greater average body weight was found in T16 vs T14 (384.25 vs 378.38 kg; P<0.05) and the difference continued until day 261 (612.35 vs 595.54 kg; P<0.05); regarding ADG, hot carcass weight and cold carcass weight the result were: 1.50 vs 1.46 kg (P<0.05), of ADG kg/d; 367.34 vs 360.35 kg (P<0.05) and 366.68 vs 358.78 kg (P<0.05). No difference between treatments were found in dorsal fat, marbling, pH and meat color. The results suggest that an increase from 14 m2/animal to 16 m2/animal improves the production results as well as the hot and cold carcass weight, with no effect on the quality traits of the carcass and beef.

Resumen Se determinó cómo la cantidad de espacio vital asignado en el corral de engorda, influye tanto en los indicadores de producción como en los rasgos de calidad de la canal y la carne obtenidas de novillos Holstein mediante la formación de dos grupos de tratamiento, T14: 65 novillos/corral (14 m2/cabeza de espacio permitido) y T16: 57 novillos/corral (16 m2/cabeza de espacio permitido), con cinco repeticiones en cada tratamiento. El peso promedio de llegada fue de 238 ± 0.74 kg. Durante el período de engorda el ganado se alimentó dos veces al día con dietas comerciales. Los novillos se sacrificaron después de un período de 261 días. En el momento del primer reimplante se encontró un mayor peso corporal promedio en T16 vs T14 (384.25 vs 378.38 kg; P<0.05) y la diferencia se mantuvo hasta el día 261 (612.35 vs 595.54 kg; P<0.05); en cuanto a la GDP, el peso de la canal caliente y el peso de la canal fría, los resultados fueron: 1.50 vs 1.46 kg (P<0.05), de GDP kg/día; 367.34 vs 360.35 kg (P<0.05) y 366.68 vs 358.78 kg (P<0.05). No se encontraron diferencias entre los tratamientos en la grasa dorsal, el marmoleado, el pH y el color de la carne. Los resultados sugieren que un aumento de 14 m2/animal a 16 m2/animal mejora los resultados productivos, así como el peso de la canal caliente y fría, sin afectar a los rasgos de calidad de la canal y la carne.
