ABSTRACT Macaw palm (Acrocomia aculeata) is a potential raw material for biodiesel production owing to its high oil content. In this study, a model is created that can estimate the oil percentage in Macaw fruit using spectral indices obtained via computer vision. Ninety Macaw fruits are used to perform an experiment. They are categorized into three stages of maturation and counted in terms of weeks after flowering. Images of the fruits are captured using a multispectral camera in the visible spectral region (RGB) and infra-red regions (NIR), which allows spectral indices to be obtained. A model is established using the principal component regression method and used to estimate the oil content based on the colorimetric characteristics of Macaw palm fruits. The selected model is composed of the first two principal components, which indicate an explanatory potency of 91.57% of the variance. Applying this information to the validation data, the model exhibits a determination coefficient of 0.91, mean square error of 10.61%, and standard error of 5.46% in terms of the oil content, which indicates that computer vision is a promising alternative method for estimating oil content.

Abstract This article seeks to unveil the effects of the accountability model in the relationship between teachers and students in high performance schools in Ceará, questioning the place that children of the 2nd grade of elementary school take regarding the policy represented by the “Escola Nota Dez Prize”. The study, qualitative in its nature, has investigated this reality in awarded schools in five municipalities from different regions of the state, using semi-structured interviews with teachers of the 2nd grade of elementary school. The analysis of the empirical material was based on the concept of fusion of horizons from Gadamerian hermeneutics. It was verified that the obsession to work systematically the achievement of the award tends to impose a “standard student”, where the child is passive, a receiver and reproducer of knowledge.

Resumen Este artículo busca revelar los efectos del modelo de rendición de cuentas en la relación entre profesores y alumnos en escuelas de alto rendimiento en Ceará, cuestionando el lugar que ocupan los niños del 2º año de la Enseñanza Fundamental frente a la política representada por el Prêmio Escola Nota Dez. De carácter cualitativo, investigó esta realidad en escuelas premiadas de cinco municipios de diferentes regiones del estado, a través de entrevistas semiestructuradas con docentes del 2º año de la Enseñanza Fundamental. El análisis del material empírico se basó en la noción de fusión de horizontes de la hermenéutica gadameriana. Se constató que la obsesión por trabajar sistemáticamente el alcance del premio tiende a imponer un estándar estudiantil, con el niño ocupando un lugar pasivo, como receptor y reproductor de saberes.

Resumo O presente artigo versa sobre as musicovivências do reggae, enquanto estética musical que emerge das condições impostas pelos processos de colonização, racialização e subalternização na Jamaica. Busco discutir as relações estabelecidas entre os elementos de formação do estilo musical jamaicano e sua constituição como expressão do processo de (re)existências das populações afrodiaspóricas nas Américas. A metodologia de análise utilizada para consecução da pesquisa atrelou dois elementos: uma revisão de literatura, reconstituindo os processos sócio-históricos e culturais que serviram de base para a formação do reggae, e o seu intercruzamento com os elementos biográficos dos principais músicos de reggae jamaicano, entre as décadas de 1960 e 1980. Busca-se assim delimitar a peculiaridade da relação entre música reggae e o cotidiano periférico vivenciado pelos músicos na composição do reggae. Demonstro as condições e estratégias de produção de um estilo que considero outsider, em relação ao estilo estético ocidental.

Abstract The present article considers the musical experiences of reggae, as an aesthetic that emerges out of conditions imposed by processes of colonization, racialization and subalternization in Jamaica. I seek to discuss the relationships established between the elements that make up this Jamaican musical style and its formation as an expression of the process of (re)existence of Afrodiasporic populations in the Americas. The methodology of analysis used to develop this research involved two strands: a revision of the literature, reconstituting the socio-historical and cultural contexts that acted as a foundation for the emergence of reggae, and their interconnections with the biographical narratives of the main Jamaican reggae musicians between the 1960s and 80s. Seeking in this manner to outline the particularity of the relationship between reggae and the day-to-day experience of marginalization of the musicians in the emergence of reggae, I present the conditions and strategies for the production of a musical genre that I consider to be an outsider in relation to the Western aesthetic model.

RESUMO A qualidade e o valor da bebida do café podem ser afetados pela contaminação de impurezas durante a torra e moagem. Métodos que permitem o controle de qualidade do produto comercializado são importantes para atender aos padrões exigidos pelos consumidores e pela indústria. Objetivou-se neste estudo estimar o percentual de impurezas contidas no café usando descritores texturais e colorimétricos obtidos a partir de imagens digitais. Os grãos de café arabica (Coffea arabica L.) com 100% de pureza foram submetidos a processos de torra e moagem, e o café moído inicialmente puro foi gradativamente contaminado por impurezas. As imagens digitais foram coletadas em amostras de café com 0, 10, 30, 50 e 70% de impurezas. A partir das imagens, foram obtidos os descritores texturais de histogramas (média, desvio padrão, entropia, uniformidade e terceiro momento) e os descritores colorimétricos (espaço de cores RGB e espaço de cores HSI). O método de regressão de componente principal (PCR) foi aplicado ao grupo de dados de descritores texturais e colorimétricos para o desenvolvimento de modelos lineares para estimativa de impurezas do café. Os modelos selecionados para o grupo de dados dos descritores texturais e o grupo de dados dos descritores colorimétricos foram compostos por dois e três componentes principais, respectivamente. O modelo dos descritores colorimétricos apresentou maior capacidade de estimativa da porcentagem de impurezas no café quando comparado com o modelo dos descritores texturais.

ABSTRACT The quality and price of coffee drinks can be affected by contamination with impurities during roasting and grinding. Methods that enable quality control of marketed products are important to meet the standards required by consumers and the industry. The purpose of this study was to estimate the percentage of impurities contained in coffee using textural and colorimetric descriptors obtained from digital images. Arabica coffee beans (Coffea arabica L.) at 100% purity were subjected to roasting and grinding processes, and the initially pure ground coffee was gradually contaminated with impurities. Digital images were collected from coffee samples with 0, 10, 30, 50, and 70% impurities. From the images, textural descriptors of the histograms (mean, standard deviation, entropy, uniformity, and third moment) and colorimetric descriptors (RGB color space and HSI color space) were obtained. The principal component regression (PCR) method was applied to the data group of textural and colorimetric descriptors for the development of linear models to estimate coffee impurities. The selected models for the textural descriptors data group and the colorimetric descriptors data group were composed of two and three principal components, respectively. The model from the colorimetric descriptors showed a greater capacity to estimate the percentage of impurities in coffee when compared to the model from the textural descriptors.

Abstract Licania macrophylla is a medicinal plant from the Amazon. It is mainly used in the form of a decoction and has been reported to contain several phenolic compounds. However, the effect of seasonality on the phenolic composition and antioxidant potential of this plant has not been well studied, especially in the Amazon region, an area affected by the rainy and less-rainy seasons. Therefore, we evaluated the seasonality of these aromatic compounds and the antioxidant potential of the extracts from L. macrophylla stem bark. We also determined the correlation between the extraction methods used and precipitation levels during each period for 1 year. The total flavonoid and phenolic content, DPPH-scavenging potential, percentage of phosphomolybdenum complex reduction, and iron-reducing power were quantified. The levels of phenolic compounds were the highest in June, whereas those of flavonoids were the highest in September and October; however, these differences were not significant. The extracts from April, November, and June showed the best results for DPPH scavenging, phosphomolybdenum reduction, and iron reduction power, respectively. Significant differences in the phenolic content and DPPH-scavenging activity were observed between the more- and less-rainy seasons. The total phenolic content was positively correlated with FRAP and DPPH, whereas flavonoid levels were negatively correlated.

Resumo: Políticas de accountability educacional têm sido adotadas no mundo inteiro, baseadas em processos de avaliação, prestação de contas e responsabilização. A eficiência desses instrumentos ainda é questionada, sendo criticados seus efeitos sobre as escolas, com base em lógicas gerenciais. Este artigo objetiva investigar o Prêmio Escola Nota Dez, uma iniciativa do Programa Alfabetização na Idade Certa (Paic), coordenado pelo governo estadual do Ceará. Essa política concede incentivos financeiros às escolas municipais, além de promover uma cooperação entre escolas para repercutir práticas de gestão. A pesquisa, de natureza quantitativa e qualitativa, utilizou, como procedimentos metodológicos, análise dos documentos legais e normativos referentes ao Prêmio, como leis, decretos, manuais de operação, e dados sobre escolas e sobre recursos financeiros que foram examinados com o uso de estatística descritiva para o período 2008-2018. Os resultados mostram que o Prêmio limita o número de escolas participantes, permite que uma mesma escola ganhe alternadas vezes e favorece os municípios com redes escolares pequenas. Caracteriza-se como uma política de accountability high stake pelas regras estabelecidas para concessão aos beneficiários, envolvendo recursos financeiros, e parece induzir expressivo reordenamento das redes escolares municipais, que reduziram a quantidade de escolas ofertantes dos anos iniciais do ensino fundamental.

Abstract: Educational accountability policies have been adopted worldwide, based on processes of evaluation, account and accountability. There are still questions around this instruments’ efficiency, and criticism over their effects on schools based on managerial logic. This article aims to investigate Escola Nota Dez Award, an initiative of Programa Alfabetização na Idade Certa (Paic), managed by state government of Ceará. This policy provides financial incentives to municipal schools, in addition to promoting cooperation between schools to reflect management practices. The research, of quantitative and qualitative nature, used, as methodological procedures, the analysis of legal and normative documents referring to the Award, such as laws, decrees, operation manuals and data on schools and on financial resources that were analyzed using descriptive statistics for the period 2008 - 2018. Results show that the Award limits the number of participating schools, allows the same school to win alternately and favors municipalities with small school networks. It is characterized as a high-stake accountability policy due to the rules established for granting to beneficiaries, involving financial resources, and it seems to induce a significant reorganization of the municipal school networks, which reduced the number of schools offering the early years of elementary school.

Resumen: Se han adoptado políticas educativas de responsabilidad en todo el mundo, basadas en procesos de evaluación, rendición de cuentas y responsabilización. Aún se cuestiona la eficacia de estos instrumentos y se critican sus efectos en las escuelas, basándose en lógicas de gestión. Este artículo tiene como objetivo investigar el Prêmio Escola Nota Dez, una iniciativa del Programa Alfabetização na Idade Certa (Paic), gestionado por el gobierno estatal de Ceará. Esta política proporciona incentivos financieros a las escuelas municipales, además de promover la cooperación entre las escuelas para reflejar las prácticas de gestión. La investigación, de naturaleza cuantitativa y cualitativa, utilizó, como procedimientos metodológicos, el análisis de los documentos legales y normativos que se refieren al Premio, tales como leyes, decretos, manuales de operación y datos en escuelas y en recursos financieros que fueron analizados utilizando estadísticas descriptivas para el periodo 2008-2018. Los resultados muestran que el Premio limita el número de escuelas participantes, permite que una misma escuela gane sucesivamente y favorece a los municipios con pequeñas redes escolares. Se caracteriza como una política de rendición de cuentas de alto riesgo por las reglas establecidas para otorgar a los beneficiarios, que involucran recursos financieros, y parece inducir una reorganización significativa de las redes escolares municipales, lo que redujo el número de escuelas que ofrecen los primeros años de la escuela primaria.

RESUMO A aplicação de métodos ópticos para análise da qualidade de frutos apresenta vantagens em comparação a métodos convencionais, tais como, a não destruição da amostra e a possibilidade de automatizar processos de controle de qualidade. Objetivou-se com este trabalho comparar redes neurais artificiais desenvolvidas a partir de índices de atividade biológica obtidos pela técnica óptica do biospeckle laser e a partir das variáveis físico-químicas obtidas por técnicas convencionais destrutivas, avaliando o acerto de classificação quanto a maturação de tomates utilizando como referência uma classificação previamente realizada por inspeção visual. Para realização do experimento foram utilizados 150 tomates divididos em três estádios de maturação. A análise multivariada de componentes principais foi realizada visando avaliar a interação da variância dentro dos grupos de dados obtidos pela técnica do biospeckle laser e pelos métodos laboratoriais destrutivos. Duas redes neurais artificiais foram desenvolvidas, sendo a primeira rede neural gerada utilizando os índices de atividade biológica como vetores de entrada e a segunda rede neural gerada utilizando as variáveis físico-químicas como vetores de entrada. A comparação da capacidade de acerto entre as duas redes neurais, tendo como base uma classificação de referência, foi realizada a partir dos parâmetros índice Kappa e exatidão global. A variância da maturação em função dos índices de atividade biológica pôde ser explicada pelo primeiro componente principal. A rede neural gerada a partir dos índices de atividade biológica apresentou melhor desempenho para classificar os tomates nos três estádios de maturação apresentando índice Kappa significativo e uma exatidão global de 67,5%.

ABSTRACT Optical methods for analysing fruit quality have various advantages compared to conventional methods, including not destroying the sample and the possibility of automating the quality control process. The aim of this study was to compare artificial neural networks developed from biological activity indices obtained using the biospeckle laser optical technique, and from physico-chemical variables obtained by conventional destructive techniques, through an evaluation of their precision in classifying ripe tomatoes, using as a reference an earlier classification carried out by visual inspection. A total of 150 tomatoes were used in the experiment, divided into three ripening stages. Multivariate principal component analysis was used to evaluate interaction of the variance within the groups of data obtained using the biospeckle laser technique and destructive laboratory methods. Two artificial neural networks were developed, the first generated using biological activity indices as input vectors, and the second using physico-chemical variables. The precision of the two neural networks was compared using the Kappa index and overall accuracy, and was based on a reference classification. The variation in ripening as a function of the biological activity indices was explained by the first principal component. The neural network generated from the biological activity indices showed the best performance in classifying the tomatoes into the three ripening stages, with a significant Kappa index and an overall accuracy of 67.5%.

ABSTRACT Bulk transportation of tomatoes is a step with high occurrence of mechanical impacts, leading to increased losses and reduction in the quality of fruits arriving at the industry and reaching the consumer market. The present study aimed to evaluate variations in physical-chemical parameters associated with the quality of tomato fruits, occurred during bulk transportation, using an approach based on principal component analysis. The experiment was conducted in the municipality of Morrinhos - Goiás, Brazil. Firmness, titratable acidity, total soluble solids, pH and mass loss were evaluated in the fruits at three times: during transportation on dirt road; after transportation on dirt road and during transportation on asphalt-paved road; after transportation on dirt and asphalt-paved roads and arrival at the processing yard. Principal component analysis was used to identify which physical-chemical attributes were most affected by transportation and generate quality indices of tomato fruits according to the physical-chemical attributes. Variation in the attributes was explained by the first three principal components, which had cumulative explained variance of 78.37%. Titratable acidity, soluble solids and mass loss had the highest correlations with the most representative principal component, thus being the most affected attributes during the bulk transportation of the fruits.

ABSTRACT Coffee growers who produce the robusta species (Conilon) have sought to increase productivity and drink quality by improving production techniques. Artificial vision systems can assist in increasing the efficiency of operations associated with crop management. This study aimed to obtain colorimetric characteristics of robusta coffee fruits at different stages of maturity and use them for classifying fruits from digital images. A digital camera with spectral resolution in the visible was used to acquire images from 60 samples of coffee fruits at the green, cherry, and over-ripe stages of maturity. Colorimetric variables were extracted from the RGB, HIS, and L*a*b* color models and correlated with the physicochemical attributes of the fruits. The principal component analysis associated with the k-means technique was applied to the colorimetric variables that showed a significant correlation with the physical-chemical attributes. The colorimetric variables were reduced to a principal component, which presented an explanatory percentage of the variance of 82.33%. The clustering obtained by the application of the k-means technique showed the feasibility of using images for the automatic classification of robusta coffee fruits, with an overall accuracy of 100%.

RESUMO Variáveis obtidas por métodos ópticos podem apresentar correlação com características relacionadas à qualidade e maturação de tomates. Neste contexto, objetivou-se com este estudo analisar a correlação entre as variáveis colorimétricas e físico-químicas de tomates, agrupando-os em função do estádio de maturação, utilizando análise multivariada. O experimento foi realizado utilizando 150 frutos em três estádios de maturação (imaturos, coloridos e maduros). As variáveis físico-químicas foram obtidas por meio de métodos tradicionais. As variáveis colorimétricas foram obtidas a partir de uma câmera digital no espaço de cor RGB. A análise da correlação entre as variáveis colorimétricas e físico-químicas foi realizada por meio do coeficiente de Pearson. A análise de componentes principais associada à técnica de agrupamento k-means foi aplicada em três grupos de dados: variáveis RGB isoladas; variáveis colorimétricas calculadas pela relação entre as bandas RGB (índices colorimétricos); e variáveis físico-químicas. As variáveis colorimétricas apresentam maior capacidade explicativa da variação da maturação quando comparadas às variáveis físico-químicas. O conjunto de índices colorimétricos apresentou o maior desempenho no agrupamento (exatidão global = 0,98) dos tomates em função da maturação.

ABSTRACT Results of evaluations using optical evaluation methods may be correlated with tomato quality and maturation. In this context, the objective of this study was to evaluated the correlation between tomato colorimetric and physico-chemical variables, clustering them as a function of maturation stages, using multivariate analysis. The experiment was conducted using 150 fruits and three maturation stages (immature, light red and mature). The physico-chemical variables were evaluated through traditional methods. The colorimetric variables were assessed on images in RGB color model taken with a digital camera. The correlation between colorimetric and physico-chemical variables was analyzed using the Pearson’s coefficient. Principal components analysis and k-means clustering method was applied to three data set: RGB isolated variables; colorimetric variables calculated by relation between the RGB bands (colorimetric indexes); and physico-chemical variables. The colorimetric variables present higher explanatory capacity of the maturation variation than physico-chemical variables. The colorimetric indexes presented higher performance in clustering (accuracy of 0.98) tomatoes as a function of maturation.

Abstract Multinucleate cell angiohistiocytoma is a rare, benign vascular proliferation of unknown etiology. It occurs mainly in middle-aged women and usually affects the acral regions; the lesions appear as discrete, grouped, and asymptomatic violaceous papules. Histopathology shows proliferation and dilated small vessels in the papillary dermis, fibrous stroma with thickened collagen bundles, and multinucleated giant cells. To date, there are approximately 140 cases described in the indexed literature. This report presents the case of a 62-year-old woman with a typical clinical condition, who chose not undergo treatment, considering the benign character of her illness. The clinical and immunohistological aspects of this unusual dermatological entity are emphasized.

RESUMO A produção de cebola é uma atividade agrícola cujo rendimento está associado a fatores ambientais, de mercado e ao manejo cultural. Objetivou-se com este estudo avaliar o custo de produção de cebola em função do sistema de preparo adotado e do teor de água do solo no momento de realização das operações. Foram avaliados três sistemas de preparo: P1 - uma aração + duas gradagens + duas operações de encanteiramento; P2 - duas gradagens + uma operação de encanteiramento; P3 - uma gradagem + uma operação de encanteiramento; e quatro teores iniciais de água do solo: 12, 15, 23 e 26%, em experimento conduzido no perímetro irrigado Tourão, Juazeiro, BA (9° 24’ 07.3” S; 40° 26’ 08.7” W, e altitude de 376 m), em 2017, em parcelas subdivididas, no delineamento em blocos casualizados, com quatro repetições. Foram determinados os custos referentes às operações mecanizadas, operações manuais, insumos e a irrigação da cultura. A eficiência econômica foi avaliada por meio das variáveis custo total e custo unitário de produção da cebola, receita bruta, receita líquida e taxa interna de retorno. A utilização do sistema de preparo com uma gradagem, um encanteiramento e semeadura, na condição de teor de água do solo a 23%, resultou em maior eficiência econômica.

ABSTRACT Onion production is an agricultural activity whose yield is associated with environmental, market and cultural management factors. The objective of this study was to evaluate the cost of onion production as a function of the tillage system adopted and the soil water content at the moment of the operations. Three tillage systems were evaluated: P1 - one plowing + two harrowings + two seedbed raising operations; P2 - two harrowings + one seedbed raising operation; P3 - one harrowing + one seedbed raising operation; and four soil water contents: 12, 15, 23 and 26%, in experiment conducted at the Tourão irrigated perimeter, Juazeiro, BA, Brazil (9° 24’ 07.3” S; 40° 26’ 08.7” W, and altitude of 376 m), in 2017, in split plots, in a randomized block design, with four repetitions. The costs related to mechanized operations, manual operations, inputs and crop irrigation were determined. The economic efficiency was evaluated through the variables total cost and unit cost of onion production, gross revenue, net revenue and internal rate of return. The use of the tillage system with one harrowing, one seedbed raising operation and seeding, under the condition of 23% soil water content, resulted in higher economic efficiency.

ABSTRACT Objective: Describe the clinical management of an atypical Le Fort I fracture case. Case presentation: A 33-year-old patient was brought to the Surgical and Maxillofacial Traumatology Service of Humberto Lucena Senatorial Emergency and Trauma Hospital in Joao Pessoa (PB), Brazil, after undergoing physical aggression. The patient was conscious and lucid. Clinical examination revealed sinking of the middle third of the face with edema and bilateral periorbital ecchymosis. Visual acuity and ocular motricity were preserved in both eyes. A cut-contusion injury on the upper lip, maxillary mobility when handled and discrete occlusal dystopia were also observed. Imaging examination identified a high bilateral Le Fort I fracture. The therapeutic approach chosen was fracture reduction and fixation with plates and screws. After a period of two months, the patient is healing well without any apparent functional or aesthetic alteration. Conclusions: Atypical Le Fort I fractures are not frequent; however, a number of etiologies besides the impact force may bring about them. Treatment should be based on the one for classical Le Fort I fractures with adjustments to the surgical access approach.

RESUMEN Objetivo: Describir los manejos clínicos realizados en una víctima de fractura de Le Fort I atípica. Reporte de caso: Un hombre de 33 años fue llevado al Servicio de Traumatología Quirúrgica y Maxilofacial del Hospital de Trauma y Emergencias Senatorial Humberto Lucena - Joao Pessoa (PB), Brasil, víctima de agresión física. El paciente estaba consciente y lúcido. Clínicamente, se observó hundimiento del tercio medio de su cara con edema y equimosis periorbital bilateral. La agudeza visual y la motricidad ocular se conservaron en ambos ojos. También se observaron herida constuso-cortante en el labio superior, movilidad maxilar cuando se manipula y discreta distopia oclusal. El examen de imagen identificó una fractura bilateral alta de Le Fort I. El enfoque terapéutico elegido fue la reducción de la fractura y la fijación con placas y tornillos. Después de un período de 2 meses, el paciente está evolucionando bien sin aparentes alteraciones funcionales o estéticas. Conclusiones: las fracturas atípicas de Le Fort I no son frecuentes, sin embargo, diferentes etiologías añadidas a la fuerza de impacto pueden justificarlas. El tratamiento debe basarse en las fracturas clásicas de Le Fort I con ajustes en el abordaje de acceso quirúrgico.

O presente artigo tem como objetivo central compreender os processos de interferência da indústria fonográfica sobre a música popular. Diante da expansão da lógica formal capitalista no campo da arte, a relação entre objetividade e subjetividade será a mola propulsora que utilizaremos para analisar paradoxos no processo de reprodução da música popular moderna, tais como indústria cultural e a reprodutibilidade técnica. Assim, partindo da análise do reggae jamaicano, buscamos ampliar o postulado adorniano sobre massificação da música para uma análise na qual seja possível investigar a experiência de produção artística periférica, como a da música popular jamaicana. Essa problemática abriu espaço para a discussão acerca da possibilidade de a indústria fonográfica ter múltiplas formas de atuação, a partir das contingências geradas pela singularidade do funcionamento desigual das condições econômicas, políticas e culturais de cada região, não perdendo de vista que as configurações locais são partes integrantes do modo de produção capitalista.

This article is about popular music, focusing in the relations built by music in face of capitalism’s expansion in the arts’ field. For this instance, the relations between objectivity and subjectivity will be the plot from where we will analyze the paradoxes in the process of modern popular music reproduction, such as: culture industry and the work of art in the age of its technological reproduction. So, starting from the Jamaican reggae, we seek to wise Adorno’s perspective about music investigation to an analysis where is possible to investigate the outlying artistic production, as the popular music that rises in Jamaica. This argument opened space to a discussion about the possibility of the phonographic industry have multiple actuation forms developed from its contingencies that are created by the singularities of its unequal way of work in face of different economic, political and cultural circumstances, keeping in sight that local realities are integrated to the capitalism mode of production.

Le sujet de cet article c’est la musique populaire. On prend la question des rapports entre la musique et la logique de l’expansion capitaliste au domaine de l’art. Pour cela, la relation entre l’objectivité et la subjectivité c’est la force motrice de notre analyse sur les paradoxes du procès de reproduction de la musique populaire moderne, tels que : l’industrie culturelle et la reproductibilité technique. On part de la musique jamaïcaine pour faire la critique au postulat adornien de la négativité appliqué à la musique erudite, en visant comprendre avec lui, aussi, la musique populaire, particulièrement la musique pop des régions périphériques du monde. Cette voie des discussions nous ouvre des multiples possibilités des investigations sur l’industrie phonographique, issues des contingences générées par la singularité du fonctionnement inégal des conditions économiques, politiques et culturelles de chaque région, sans oublier que les configurations locales font partie intégrante de mode de production capitaliste.

Abstract We present a case of atypical presentation of secondary syphilis with extensive lymph node involvement and pulmonary lesions, initially suspected as lymphoma. The patient presented with weight loss, dry cough, chest pain, palpable lymph nodes in several peripheral chains, and multiple pulmonary nodules and masses on chest imaging. The key features for secondary syphilis diagnosis were a lymph node biopsy suggestive of reactive lymphadenopathy, positive serologic tests for syphilis, and complete recovery after antisyphilitic treatment.
