Abstract The objective of this work was to compare the use of noninformative and informative priors in Bayesian models, as well as to evaluate the viability of including informative priors in the estimation of variance components and genetic values in soybean breeding programs. The used phenotypic data refer to the evaluation of 80 soybean genotypes in ten environments over three years. For each evaluated crop year, informative and noninformative priors were used, and the parameters were estimated using the Gibbs sampler algorithm. Parameter estimates from the previous crop year were used as prior information for the next evaluated crop year. The goodness-of-fit was calculated using the deviance information criterion (DIC). Selective accuracy showed the highest values for the models chosen through DIC for both crop years. However, the intervals of the highest posterior density are narrower for all models that adopted informative priors. Adding information into Bayesian inference does not always result in a better model fitting. programs 8 years algorithm goodnessoffit goodness fit DIC. . (DIC) However fitting (DIC

Resumo O objetivo deste trabalho foi comparar o uso de a priori não informativas e informativas em modelos bayesianos, bem como avaliar a viabilidade da inclusão de a priori informativas na estimativa dos componentes de variância e dos valores genotípicos em programas de melhoramento de soja. Os dados fenotípicos utilizados referem-se à avaliação de 80 genótipos de soja, em dez ambientes, ao longo de três anos. Para cada safra avaliada, foram utilizadas a priori informativas e não informativas, e os parâmetros foram estimados com uso do algoritmo de amostragem de Gibbs. As estimativas dos parâmetros da safra anterior foram utilizadas como informação prévia para a próxima safra avaliada. A qualidade do ajuste foi calculada com uso do critério de informação de desvio (DIC). A acurácia seletiva apresentou maiores valores nos modelos escolhidos por meio do DIC, para ambas as safras. No entanto, os intervalos de maior densidade a posteriori são menores para todos os modelos que adotaram a priori informativas.

Abstract This review elucidates the physiological and endocrinological processes intrinsic to puberty and ovulation induction protocols in Bos indicus and Bos taurus beef heifers. Puberty is a complex physiological event involving gonadotropic and metabolic changes that lead to sexual maturity, first ovulation, and regular reproductive cycles, enabling females to reproduce. Exposure to progesterone-based hormonal protocols, with or without additional hormones, can reduce the age at first ovulation and improve sexual maturity through stimuli in the hypothalamus-pituitary-gonadal (HPG) axis and uterine development. However, inducing puberty differs from inducing ovulation, as it does not ensure the heifer will continue cycling or be ready to establish and maintain pregnancy after hormonal exposure. Regardless of the pharmacological basis, studies consistently report that beef heifers that had a corpus luteum (CL) prior to the timed-artificial insemination (TAI) protocol, have greater expression of estrus in response to synchronization and greater pregnancy per AI compared to heifers without a CL. The combination of P4 and E2 significantly impacts uterine development, increasing reproductive efficiency. Exposure to P4 causes a positive effect on inducing ovulation. However, studies indicate that the addition of E2 esters at the time of P4 device removal increases the ovulation rate. In general, the studies showed that fertility varied according to the type of the ovulation induction protocol used, but with inconsistent results. Although ovulation induction protocols are strategic tools to accelerate sexual maturity, a holistic view of the entire system is extremely important, combining integration with genetics and nutrition to enhance the reproductive outcomes of beef heifers. Future research is needed to understand and refine these protocols, driving the efficiency of beef cattle production systems. cycles reproduce progesteronebased progesterone based hormones hypothalamuspituitarygonadal hypothalamus pituitary gonadal HPG (HPG development However exposure basis CL (CL timedartificial timed artificial TAI (TAI P E rate general used results important systems

ABSTRACT Species within the genus Corymbia are regarded as potential alternatives to Eucalyptus. In addition to having superior wood quality, Corymbia spp. are tolerant to most pests, diseases, and abiotic stresses that affecting Eucalyptus plantations, including physiological disorders, water deficit, and wind damage. However, environmental stresses stimulate kino production, which decreases the quality of pulp and sawn wood. This study aimed to develop a method for evaluating kinoand estimate genetic parameters in Corymbia. For this, 16 Corymbia (C. citriodora × C. torelliana) hybrid clones and 5 clones of Eucalyptus were used. Two evaluation methods (M1 and M2) were tested for kino evaluation; M1 consisted of drilling the bark with Pilodyn and M2 consisted of drilling the heartwood with Pilodyn. The following kino parameters were evaluated: exudation incidence, exudate length which flowed over the stem, and exudate weight. Genetic parameters were estimated by a mixed model method (REML/BLUP). The significance of random effects of the statistical model was tested by the likelihood ratio test. Significant clone effects were obtained for all kino parameters, except for exudate length as assessed by M2. Kino parameters determined by M1 exhibited higher heritability and accuracy. Therefore, M1 should be preferred for kino evaluation in Corymbia. spp pests diseases plantations disorders deficit damage However production this 1 C (C torelliana used M (M evaluated incidence stem weight REML/BLUP.

RESUMO Espécies do gênero Corymbia são consideradas potenciais alternativas ao eucalipto. Além de possuir madeira de qualidade superior, Corymbia spp. são tolerantes à maioria das pragas, doenças e estresses abióticos que afetam as plantações de eucalipto, incluindo distúrbios fisiológicos, déficit hídrico e danos causados pelo vento. No entanto, as tensões ambientais estimulam a produção de kino, o que diminui a qualidade da celulose e da madeira serrada. Este estudo teve como objetivo estabelecer um método para avaliação de kino e estimativa de parâmetros genéticos em Corymbia. Para isso foram utilizados 16 clones híbridos de Corymbia (C. citriodora × C. torelliana) e 5 clones de Eucalyptus. Dois métodos (M1 e M2) foram testados para avaliação; M1 consistiu na perfuração da casca com Pilodyn e M2 consistiu na perfuração do cerne com Pilodyn. Foram avaliados os seguintes parâmetros: incidência de exsudação, comprimento do exsudato que fluiu sobre o caule e peso do exsudato. Os parâmetros genéticos foram estimados por um método de modelo misto (REML/BLUP). A significância dos efeitos aleatórios do modelo estatístico foi testada pelo teste da razão de verossimilhança. Efeitos clones significativos foram obtidos para todos os parâmetros, exceto para o comprimento do exsudato avaliado por M2. Os parâmetros determinados por M1 apresentaram maior herdabilidade e precisão. Portanto, M1 deve ser preferido para avaliação de kino em Corymbia. eucalipto superior spp pragas fisiológicos vento entanto serrada 1 C (C torelliana Eucalyptus M (M exsudação REML/BLUP.

Abstract Background There are few studies related to Coronavirus Disease 2019 (COVID-19) on the prevalence and nature of pain symptoms after hospital discharge, especially in individuals who develop moderate to severe disease forms. Therefore, this study aimed to evaluate the presence of chronic pain in patients discharged after hospitalization for COVID-19, and the relationship between the presence of chronic pain and intensive care stay, demographics, and risk factors for the worst Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) outcome. Methods A cross-sectional observational study was carried out on patients with COVID-19 who recovered after hospitalization. Patients were recruited at the least 3 months after discharge and their hospital's health files were prospected. The variables evaluated were demographics, the severity of SARS-CoV-2 infection (considering the need for intensive care), and the presence of chronic pain. The results were shown in a descriptive manner, and multivariate analysis expressed as Odds Ratios (ORs) and respective Confidence Intervals (CIs) for the outcomes studied. Statistical significance was set at p < 0.05. Results Of 242 individuals included, 77 (31.8%) reported chronic pain related to COVID-19, with no correlation with the severity of infection. Female sex and obesity were associated with a higher risk for chronic pain with ORs of 2.69 (Confidence Interval [95% CI 1.4 to 5.0]) and 3.02 (95% CI 1.5 to 5.9). The limbs were the most affected areas of the body. Conclusion Chronic pain is common among COVID-19 survivors treated in hospital environments. Female sex and obesity are risk factors for its occurrence. 201 COVID19 COVID 19 (COVID-19 forms Therefore COVID19, 19, stay demographics SARSCoV2 SARSCoV SARS CoV (SARS-CoV-2 outcome crosssectional cross sectional COVID-1 hospitals s prospected SARS-CoV- considering care, , care) manner (ORs CIs (CIs studied 005 0 05 0.05 24 included 7 31.8% 318 31 8 (31.8% 269 69 2.6 95% 95 [95 14 1 4 1. 5.0 50 5 5.0] 302 02 3.0 (95 15 5.9. 59 5.9 . 9 5.9) body environments occurrence 20 COVID1 (COVID-1 (SARS-CoV- COVID- SARS-CoV 00 0.0 31.8 (31.8 26 6 2.

Abstract Background: Conventional dental care is often impossible in patients with Autism Spectrum Disorder (ASD). Non-collaborative behaviors, sometimes associated with aggressiveness, are usual justifications for premedication in this population. Thereby, this research focuses on the effects of oral midazolam versus oral ketamine plus midazolam as preanesthetic medication in ASD. Methods: The sample included 64 persons with ASD, aged 2-59 years, scheduled for dental care under general anesthesia. The primary objective of this study was to compare degrees of sedation between two parallel, double-blinded, equally proportional groups randomized to receive oral midazolam (0.5 mg.kg−1, maximum 15 mg) or oral midazolam (0.5 mg.kg−1) associated with oral S(+)-ketamine (3 mg.kg−1, maximum 300 mg). The secondary outcomes were the need of physical stabilization to obtain intravenous line, awakening time, and occurrence of adverse events. Results: According to the dichotomous analysis of sedation level (Ramsay score 1 and 2 versus Ramsay ≥ 3), oral association of S(+)-ketamine and midazolam improved sedation, with increased probability of Ramsay ≥ 3, Relative Risk (RR) = 3.2 (95% Confidence Interval [95% CI] = 1.32 to 7.76) compared to midazolam alone. Combined treatment also made it easier to obtain venous access without physical stabilization, RR = 2.05 (95% CI = 1.14 to 3.68). There were no differences between groups regarding awakening time and the occurrence of adverse events. Conclusion: The association of oral S(+)-ketamine with midazolam provides better preanesthetic sedation rates than midazolam alone and facilitates intravenous line access in patients with autism.

Resumo O objetivo deste trabalho foi estimar os parâmetros genéticos e avaliar a diversidade genética de 12 genótipos de lima ácida 'Tahiti' (Citrus latifolia) enxertados em dois porta-enxertos. O experimento foi conduzido de julho de 2017 a janeiro de 2019, no município de São Mateus, no estado de Espírito Santo, Brasil. Foram mensuradas características vegetativas (diâmetro de caule, diâmetro de projeção de copa e altura de planta), produtivas (rendimento e número de frutos) e de qualidade de frutos (diâmetros de fruto, teor de sólidos solúveis e rendimento de suco). Utilizou-se modelo misto para estimar os coeficientes de herdabilidade e repetibilidade, bem como predizer os valores genéticos. A diversidade entre os enxertos foi obtida por meio da diferença da distância euclidiana média padronizada, e os genótipos foram agrupados pelo método de Tocher modificado. A qualidade do agrupamento e a importância dos caracteres foi avaliada pela análise de componentes principais (ACP). Observou-se variabilidade genética, o que indica a possibilidade de seleção de genótipos superiores. O método de Tocher mostrou a presença de três grupos de genótipos, o que foi congruente com os resultados da ACP. O uso de técnicas multivariadas permite a seleção e a recomendação de genótipos superiores de lima ácida 'Tahiti'. 1 Tahiti 'Tahiti Citrus latifolia portaenxertos. portaenxertos porta enxertos. porta-enxertos 201 2019 Mateus Santo Brasil caule planta, planta , planta) diâmetros fruto suco. suco . suco) Utilizouse Utilizou se repetibilidade padronizada modificado ACP (ACP) Observouse Observou Tahiti. 20 (ACP 2

Abstract The objective of this work was to estimate the genetic parameters and to evaluate the genotypic diversity of 12 'Tahiti' acid lime (Citrus latifolia) genotypes grafted onto two rootstocks. The experiment was carried out from July 2017 to January 2019, in the municipality of São Mateus, in the state of Espírito Santo, Brazil. Vegetative (stem diameter, canopy projection diameter, and plant height), productive (yield and fruit number), and fruit quality (fruit diameter, soluble solids content, and juice yield) traits were determined. A mixed model was used to estimate heritability and repeatability coefficients, as well as to predict clonal values. Scion diversity was determined through the standardized mean difference of Euclidean distances, and genotypes were clustered by modified Tocher. Clustering quality and trait importance were evaluated using the principal component analysis (PCA). Genotypic variance was observed, which is indicative of the possibility of selection of superior genotypes. The Tocher method showed the presence of three clusters, which is in alignment with the PCA results. The multivariate analyses allows of the selection and the recommendation of superior 'Tahiti' acid lime genotypes. 1 Tahiti 'Tahiti Citrus latifolia rootstocks 201 2019 Mateus Santo Brazil stem diameter height, height , height) yield number, number number) content coefficients values distances PCA. .

RESUMO: Neste estudo retrospectivo, são descritos os achados clínicos e anatomopatológicos das doenças fúngicas em cães e gatos no Nordeste do Brasil. Durante o período de estudo, foram revisados 6.827 exames histopatológicos (4.090 necropsias e 2.737 biópsias) de animais de companhia e diagnosticados 54 casos de infecções fúngicas. Destes, 32 casos foram diagnosticados em gatos e 22 em cães. A esporotricose foi a micose mais prevalente (19/54), seguida pela dermatofitose (9/54), criptococose (8/54), candidíase (7/54) e feo-hifomicose (4/54). Outras doenças tiveram dois casos cada, incluindo aspergilose, mucormicose e histoplasmose, enquanto a coccidioidomicose ocorreu uma vez. As micoses foram diagnosticadas por meio das lesões microscópicas associadas às características histomorfológicas do agente, evidenciadas pelas colorações de rotina e histoquímicas especiais, e ocasionalmente confirmadas pela imuno-histoquímica e cultivo microbiológico. Esse estudo retrospectivo demonstrou que apesar de incomuns, as doenças fúngicas são importantes causas de morte em cães e gatos da região, sendo os gatos a espécie mais afetada e a esporotricose, a micose mais prevalente. Os sinais clínicos estavam correlacionados com a porta de entrada da infecção, associados a lesões cutâneas localizadas ou disseminadas superficiais e profundas ou afetando órgãos parenquimatosos, especialmente em infecções sistêmicas. As lesões microscópicas eram caracterizadas principalmente por inflamação piogranulomatosa associada a estruturas fúngicas. Nos cães, as micoses ocorreram principalmente devido ao comprometimento imunológico secundária a coinfecção pelo vírus da cinomose canina.

ABSTRACT: In this retrospective study, the clinical and anatomopathological findings of fungal diseases in dogs and cats in Northeastern Brazil are described. During the study period, 6,827 histopathological examinations (4,090 necropsies and 2,737 biopsies) of companion animals were reviewed, and fungal infections were diagnosed in 54 cases. Of these, 32 cases were diagnosed in cats and 22 in dogs. Sporotrichosis was the most prevalent mycosis (19/54), followed by dermatophytosis (9/54), cryptococcosis (8/54), candidiasis (7/54), and phaeohyphomycosis (4/54). Other diseases had two cases each, including aspergillosis, mucormycosis, and histoplasmosis, whereas coccidioidomycosis occurred once. Mycoses were diagnosed through microscopic lesions associated with the histomorphological characteristics of the agent, as evidenced by routine and special histochemical stains. They were occasionally confirmed by immunohistochemistry and microbiological cultivation. This retrospective study showed that despite being uncommon, fungal diseases are important causes of death in dogs and cats in the region, with cats being the most affected species and sporotrichosis being the most prevalent mycosis. Clinical signs were correlated with the portal of entry of the infection associated with localized or disseminated superficial and deep skin lesions or affecting parenchymal organs, especially in systemic infections. Microscopic lesions were mainly characterized by pyogranulomatous inflammation associated with fungal structures. In dogs, mycoses occurred mainly owing to an immunological impairment secondary to canine distemper virus co-infection.

ABSTRACT. Multi-trait multi-environment (MTME) models were fitted to eucalyptus breeding trials data to assess residual variance structure, genetic stability and adaptability. To do so, 215 eucalyptus clones were evaluated in a randomized complete block design with 30 replicates and one plant per plot in four environments. At 36 months of age, tree diameter at breast height (DBH) and pilodyn penetration (PP) were measured. Two MTME models were fitted, for which residuals were considered homoscedastic and heteroscedastic, with the best MTME model selected using Bayesian information criterion. The harmonic mean of the relative performance of the genotypic values (HMRPGV) was used to determine stability and adaptability. Of the two models, the heteroscedastic MTME model had better fit and provided greater accuracy. In addition, genotype-by-environment interaction was complex, and there was low genetic correlation between DBH and PP. Rank correlation between the clones selected by the MTME models was high for DBH but low for PP. The HMRPGV facilitated clone selection through simultaneous evaluation of stability, adaptability, and productivity. Thus, our results suggest that heteroscedastic MTME model / HMRPGV can be efficiently applied in the genetic evaluation and selection of eucalyptus clones.

Os sinais clínicos incluíam protrusão da membrana nictante, lacrimejamento, edema palpebral, congestão ocular, destruição do globo ocular, emagrecimento e morte. A evolução clínica variou de oito a 16 meses. Macroscopicamente, observou-se espessamento das pálpebras e conjuntivas associado a numerosas estruturas parasitárias alaranjadas. No segundo surto, as lesões eram mais graves e consistiam em perda do globo ocular direito e anexos. Histologicamente, as lesões caracterizavam-se por conjuntivite linfoplasmocítica e heterofílica, multifocal a coalescente, moderada, crônica associada a hiperplasia e ectasia da glândula de Harderian e numerosas estruturas parasitárias. Os parasitas eram ovalados, achatados com ventosa oral e acetábulo e cutícula espessa contendo espículas. O diagnóstico de filoftalmíase foi realizado com base nos achados epidemiológicos, clínicos e patológicos associadas as características morfológicas dos parasitas presentes nos sacos conjuntivais compatíveis com o trematódeo Philophthalmus sp. A filoftalmíase pode ocorrer em avestruzes criados em propriedades urbanas e rurais no Nordeste do Brasil, provavelmente associado ao contato das aves com água contaminada e caracteriza-se por quadros de conjuntivite grave que pode resultar com a perda do globo ocular e morte dos animais.

ABSTRACT: This study discusses the epidemiological, clinical, and pathological characteristics of two outbreaks of ocular infection in ostriches (Struthio camelus) caused by the trematode Philophthalmus sp. The outbreaks occurred in the states of Ceará and Rio Grande do Norte in Northeast Brazil. Ostrich farming was categorized as semi-intensive farming with free access to the weir and river. The clinical symptoms for infection included nictitating membrane inflammation, epiphora (tearing), eyelid edema, ocular congestion, eyeball destruction, emaciation, and death, and the infection period ranged from 8 to 16 months. Macroscopically, thickening of the eyelids and conjunctiva were observed, with orange parasites infestation. Histologically, the lesions were characterized as lymphoplasmacytic and heterophilic, multifocal to coalescing, moderate, chronic conjunctivitis associated with hyperplasia and ectasia of the Harderian gland, and numerous parasites. The parasites were oval and flattened with an oral suction cup, acetabulum, and thick cuticle containing spicules. The diagnosis of philophthalmiasis was based on epidemiological, clinical, and pathological findings associated with the morphological characteristics of the parasites present in the conjunctival sacs which were similar to the trematode Philophthalmus sp. Philophthalmiasis can occur in ostriches raised on urban and rural properties in Northeastern Brazil, probably associated with the contact of birds with contaminated water, and is characterized by severe conjunctivitis that can result in the loss of the eyeball and death of the animals.

RESUMO: Descreve-se um caso de infarto cerebral e meningoencefalite trombótica devido a candidíase em um bezerro de sete meses de idade. A morte ocorreu três dias após o início de apatia, febre e desvio lateral da cabeça para a esquerda. As alterações macroscópicas no cérebro consistiam em assimetria dos hemisférios telencefálicos; o hemisfério direito estava aumentado, causando herniação cerebelar. Uma extensa área vermelha focal foi observada na superfície do lobo occipital direito. Nos cortes transversais do encéfalo fixado, as lesões revelaram áreas extensas, marrom-avermelhadas, moles ou cavitadas, afetando a substância branca e cinzenta desde o nível do tálamo até o cerebelo e comprimindo as estruturas subjacentes. Histologicamente, havia meningoencefalite necrossupurativa multifocal aguda, coalescente, associada a vasculite, congestão, trombose, edema, infarto e hifas fúngicas intralesionais. O diagnóstico de infarto cerebral e meningoencefalite trombótica devido a candidíase foi feito pelas alterações patológicas, coloração e características morfológicas do agente e imuno-histoquímica. O infarto cerebral e meningoencefalite trombótica em bovinos pode resultar de lesões vasculares devido à infecção por Candida sp.; embora incomum, este caso demonstra que a candidíase deve fazer parte de uma lista de diagnósticos diferenciais de lesões cerebrais graves em bovinos.

ABSTRACT: We described a case of cerebral infarction and thrombotic meningoencephalitis due to candidiasis in a seven-month-old calf. The death occurred three days after the onset of apathy, fever, and the head’s lateral deviation to the left. Macroscopic changes in the brain consisted of asymmetry of telencephalic hemispheres; the right hemisphere was enlarged, causing cerebellar herniation. A focally extensive red area was observed on the surface of the right occipital lobe. At cross-sections of the fixed brain, the lesions revealed to be extensive, red-brown, soft or cavitated areas affecting the white and grey matter from the level of the thalamus to the cerebellum and compressing subjacent structures. Histologically, there was acute, coalescent, multifocal necrosupurative meningoencephalitis, associated with vasculitis, congestion, thrombosis, edema, infarction, and intralesional fungal hyphae. The diagnosis of cerebral infarction and thrombotic meningoencephalitis due to candidiasis was made by the pathological changes, the staining and morphological characteristics of the agent, and immunohistochemistry. The cerebral infarction and thrombotic meningoencephalitis in cattle can result from vascular lesions due to infection by Candida sp.; although uncommon, this case demonstrated that candidiasis should be part of a list of differential diagnoses of severe brain injuries in cattle.

RESUMO: Descreve-se um caso de rinite por Exserohilum rostratum em um caprino, sem raça definida, fêmea, três anos, com diminuição do apetite, dispneia e deformidade facial, com evolução de aproximadamente dois meses. Durante a necropsia, observou-se que na cavidade nasal havia área focal extensa, amarelo acastanhada, irregular, ulcerada e friável, que drenava secreção purulenta acometendo o vestíbulo nasal e estendendo-se da porção caudal da concha dorsal, associada a obstrução do meato nasal, destruição do septo nasal e osso nasal palatino e vômer. Histologicamente, a lesão foi caracterizada como rinite e osteomielite piogranulomatosa e necrosante, multifocal a coalescente, aguda, crônica, associada a uma miríade de estruturas fúngicas. Morfologicamente, as hifas foram caracterizadas por paredes finas, discretamente tortuosas e septadas medindo 2 a 6 μm de diâmetro. Observamos algumas cadeias de conídios ou grupos com 8 a 10 μm de diâmetro e clamidoconídios pigmentados medindo de 7,5 a 15 μm de diâmetro. Foram positivos na histoquímica especial de Fontana Masson, Nitrato de Metenamina de Prata de Grocott e Ácido Periódico de Schiff. O agente foi determinado por meio de isolamento microbiológico associado à identificação molecular. A rinite piogranulomatosa causada por E. rostratum em caprinos é inédita, sendo o primeiro isolamento do agente em animais no Brasil e o primeiro caso de feo-hifomicose nasal na espécie caprina.

ABSTRACT: We described a case of rhinitis case caused by Exserohilum rostratum in a 3-year-old, mixed breed, afemale goat, presenting with decreased appetite, dyspnea, and face deformity, with evolution of approximately 2 months. Necropsy revealed an extensive brownish yellow, irregular, ulcerated, and friable focal lesion in the nasal cavity. Purulent secretion drained from the lesion, affecting the nasal vestibule and extending the caudal portion of the dorsal concha, associated with nasal meatus obstruction, destruction of the nasal septum, and nasal bone palatine and vomer. Histologically, the lesion was characterized as rhinitis and pyogranulomatous and necrotizing osteomyelitis (multifocal to coalescent, sharp, and chronic) and associated with a myriad of fungal structures. Morphologically, the hyphae were characterized by thin, slightly tortuous, and rarely septate walls (2-6 μm diameter), multiple chains of individual conidia or in groups (8-10 μm diameter), and pigmented chlamydoconidia (7.5-15 μm diameter). They showed positive results for the special histochemical techniques such as Fontana Masson, methenamine silver nitrate by Grocott, and periodic acid by Schiff. E. rostratum was identified as the causative agent using microbiological isolation associated with molecular identification. Pyrogranulomatous rhinitis caused by E. rostratum in goats is unprecedented, being the first isolation of the agent in animals in Brazil and the first case of nasal phaeohyphomycosis in the goats.

RESUMO: Descreve-se os achados clínicos e anatomopatológicos observados em um caso de leiomiossarcoma nasal em um equino, Quarto de Milha, macho, de cinco anos de idade, com queixa principal de diminuição do rendimento esportivo e secreção nasal purulenta bilateral. Na cavidade nasal, observou-se um nódulo obstruindo a narina esquerda associada à secreção purulenta. O nódulo era de superfície irregular, amarelada, brilhante, fibroelástica, medindo 19,4 x 6,9 x 4,3cm de tamanho, com áreas multifocais a coalescente acastanhadas, friáveis, opacas e fétidas. Ao corte, a superfície era compacta, branco-acinzentada e lisa com áreas multifocais amarelas, friáveis e irregulares, medindo 1-3,2 cm de diâmetro. No exame histopatológico foi observado proliferação de células neoplásicas fusiformes, que foram negativas na coloração de Tricrômico de Masson. O diagnóstico de leiomiossarcoma foi estabelecido com base nos aspectos morfotintoriais das células neoplásicas e confirmado através da imuno-histoquímica, no qual houve imunomarcação positiva para os anticorpos 1A4, HHF35, Desmina e S100. O leiomiossarcoma pode afetar primariamente a cavidade nasal de equinos, devendo ser incluído no diagnóstico diferencial de doenças que afetam a cavidade nasal e que provocam quadros de obstrução nasal associado a dispneia.

ABSTRACT: We described the clinical and anatomopathological findings observed in a case of nasal leiomyosarcoma in a five-year-old male Quarter Mile horse, whose main complaints were decreased sports performance and bilateral purulent nasal discharge. The nodule was observed in the nasal cavity, obstructing the left nostril and associated with purulent drainage. The nodule was of irregular shape and yellow color, measuring 19.4 cm × 6.9 cm × 4.3 cm in size, with coalescent multifocal areas that were brownish, friable, opaque, and fetid. When cut, the surface was compact, grayish-white, and smooth with yellow, friable, irregular multifocal areas, measuring 1-3.2 cm in diameter. Histopathological examination showed spindle-shaped neoplastic cells, which was negative on Masson’s trichromic stain. A diagnosis of leiomyosarcoma was established based on the morphotintorial aspects of neoplastic cells and confirmed through immunohistochemistry, with positive immunostaining for antibodies 1A4, HHF35, desmin, and S100. Leiomyosarcoma primarily affects the nasal cavity of horses and should be included in the differential diagnosis of diseases that affect the nasal cavity and cause nasal obstruction associated with dyspnea.
