Occupational noise level emitted by self-propelled harvesters during mechanized coffee harvesting / Nível de ruído ocupacional emitido por colhedoras automotrizes na colheita do cafeeiro

ABSTRACT: This study evaluated the level of occupational noise emitted by automotive harvesters during coffee harvest. For the evaluations, three self-propelled harvesters were used: Case-IH® model Coffee Express 200, with cabin; Korvan® model 9200, without cabin; and Oxbo® model 9220, with cabin. Data were collected using a noise dosimeter model DOS-700. Noise levels were assessed for the operator and assistant of each harvester. Five repetitions were performed for the operator and assistant, with each repetition consisting of 2 h of evaluation. Results obtained were compared with the action level and exposure limit of the Regulatory Norms (NR) 15 and Occupational Hygiene Norms (NHO) 01. The action levels of the NHO 01 (82 dB) and NR 15 (80 dB) regulations were exceeded for the operator and assistant in the three evaluated harvesters. Regarding the exposure limit (85 dB), the level was exceeded for the operator of the Korvan® and Case-IH® harvesters in accordance with NHO 01. In the NR 15 regulation, the exposure limit was > 85 dB for the operator of the Korvan® harvester. For the assistant, all harvesters emitted noise levels > 85 dB based on both the NHO 01 and NR 15 regulations.

RESUMO: O uso da mecanização na cafeicultura tem se mostrado de suma importância na colheita do cafeeiro, reduzindo custo e tempo desta operação. Entretanto, a intensificação da colheita mecanizada, sem o controle dos riscos ocupacionais tem exposto trabalhadores aos níveis elevados de ruído ocupacional capazes de comprometer sua saúde auditiva. O objetivo do trabalho foi avaliar o nível de ruído ocupacional emitido por colhedoras automotrizes na colheita do cafeeiro, bem como os limites de exposição e nível de ação do operador e auxiliar. Para as avaliações foram utilizadas três colhedoras automotrizes: Case-IH® modelo COFFE EXPESS 200, com cabine; OXBO® modelo 9220, com cabine; KORVAN® modelo 9200, sem cabine. A coleta dos dados foi realizada utilizando dosímetro de ruído modelo DOS-700. Foi avaliado o nível de exposição ao ruído do operador e auxiliar das colhedoras. Foram realizadas cinco repetições, sendo cada repetição formada por duas horas de avaliações. Os dados obtidos foram comparados com o nível de ação e limite de exposição das normativas NHO 01 e NR 15. O nível de ação das normativas NHO 01 (82 dB) e NR 15 (80 dB) foram ultrapassados no operador e auxiliar nas três colhedoras avaliadas. Em relação ao limite de exposição (85 dB), o nível foi ultrapassado no operador das colhedoras KORVAN® e Case-IH® de acordo com a NHO 01. Na normativa NR 15, o limite de exposição ficou acima de 85 dB no operador da colhedora KORVAN®. No auxiliar todas as colhedoras emitiram níveis de ruídos acima de 85 dB tanto na normativa NHO 01 quanto na NR 15.

Permanent tracheostomy in a horse: a case report / Traqueostomia permanente em equino: relato de caso

Problems related to the locomotor and gastrointestinal systems correspond to the highest percentage of clinical cases. However, diseases related to the respiratory system can result in low animal performance or even the animal's removal from athletic life. This paper aims to report a case of permanent tracheotomy in a horse. The animal was treated at the Jerônimo Dix-Huit Rosado Maia Veterinary Hospital - HOVET, with respiratory noise and dyspnea claims. In the anamnesis, the owner reported that the animal had been presenting respiratory difficulty for 20 days. On physical examination, respiratory noise and dyspnea were noted. Endoscopy was performed, from which a marked decrease in the arytenoid cartilage movement on the right and left sides was noted. It was possible to diagnose a stage IV case of bilateral laryngeal hemiplegia, combining clinical signs with endoscopy findings. Thus, the surgical treatment of permanent tracheostomy was chosen. After surgery, drug therapy using antibiotics and anti-inflammatory drugs was performed. In addition, a nº 6 metal tracheostomy cannula was inserted. After 36 days of hospitalization, the animal was discharged with regression of clinical signs.(AU)

Problemas relacionados aos sistemas locomotor e gastrointestinal correspondem ao maior percentual de casos clíni-cos. No entanto, doenças relacionadas ao sistema respiratório podem resultar em baixo desempenho do animal ou mesmo na retirada do animal da vida atlética. Este trabalho tem como objetivo relatar um caso de traqueotomia permanente em um cavalo. O animal foi atendido no Hospital Veterinário Jerônimo Dix-Huit Rosado Maia - HOVET, com queixas de ruído respiratório e dispneia. Na anamnese, o proprietário relatou que o animal apresentava dificuldade respiratória há 20 dias. Ao exame físico, notou-se ruído respiratório e dispneia. Foi realizada endoscopia, a partir da qual foi notada diminuição acentuada do movimento da cartilagem aritenoide nos lados direito e esquerdo. Foi possível diagnosticar um caso em estágio IV de hemiplegia laríngea bila-teral, combinando os sinais clínicos com os achados endoscópicos. Assim, optou-se pelo tratamento cirúrgico da traqueostomia definitiva. Após a cirurgia, foi realizada terapia medicamentosa com antibióticos e anti-inflamatórios. Além disso, uma cânula de traqueostomia de metal nº 6 foi inserida. Após 36 dias de internação, o animal recebeu alta com regressão dos sinais clínicos.(AU)

Morte súbita pós-estresse não traumático em cão submetido a procedimento estético / No traumatic sudden death following stetic procedure in a dog / Muerte súbita por stress no traumático durante baño y corte en un perro

Ambientes destinados a procedimentos de banho e tosa expõem os animais a grande número de agentes estressores, como ruidos de secadores, alterações na temperatura e manipulação por desconhecidos, causando apreensão, ansiedade, medo e podendo levar ao óbito por traumas físicos em tentativas de fuga ou por colapso respiratório secundário a estresse agudo. Relata-se o caso de uma cadela da raça shih-tzu de 6 meses de idade, higida e sem sinais prévios de doença respiratória ou cardiovascular, que foi a óbito algumas horas após banho em per shop, com sintomas de estresse e insuficiência respiratória aguda e com alterações necroscópicas compatíveis com hemorragia e edema pulmonar, sem sinais de trauma craniano ou em outros órgãos. Ressalta-se a importância da minimização do estresse aos animais nos procedimentos de banho e tosa, a fim de evitar esses acidentes, bem como da presença do profissional responsável pelo estabelecimento, para que tomem medidas cabíveis e precoces para reverter esses quadros potencialmente fatais.(AU)

Assessment of spatial variability of environmental conditions in different swine production typologies in tropical conditions

Comfort index and environmental variables are indicators of thermal stress conditions inside a livestock facility.The environmental conditions of ten different constructive typologies of swine-production facilities with natural ventilation were characterized in a tropical country (Antioquia, Colombia). Temperature and humidity index (THI), enthalpy (H), animal surface temperature (ST), light intensity, and noise level were measured and computed for each typology, which were located at heights above sea levels between 8:00-23:00. Data was analyzed as a function of each typology, geographical altitude, and time of the day. It was employed descriptive statistics, analysis of variance, and contour maps to analyze the data. It was found that more than 80% of the typologies presented moderate or critical stress conditions associated with the construction typology, not suitable THI and light intensity values, especially in warm and mild-mild climates. Showing high special variability inside the facilities. New typological designs and bioclimatic conditioning for swine facilities need to be studied to be implemented in these climatic conditions.(AU)

Linfoma de células T na cavidade nasal de caprino / T-cell lymphoma in the nasal cavity in goat

Background: Lymphomas are considered uncommon in goats, being the multicentric form with the highest number of cases for the species. Primary intranasal lymphomas are often diagnosed in dogs, cats, and humans. In the literature, there is only a description of a multicentric case involving the frontal sinuses and mucosa of the nasal cavity in a goat; therefore, it is important to describe unusual cases of this disease for the inclusion of new clinical and pathological characteristics in the ruminant clinic medicine. The objective of this work is to describe a case of T-cell lymphoma in the nasal cavity of a young goat. Case: The animal had dyspnea and respiratory noise for 15 days. Clinical examination showed nodulation in the right nasal cavity associated with serosanguinous secretion. Tracheostomy was performed; however, after 30 days the animal was euthanized. A sagittal plane of the head showed a pinkish-gray mass in the right and left nasal cavity, with a smooth, multilobulated surface, smooth adhering to the rostral portion of the dorsal concha and occluding the dorsal nasal meatus. Submandibular lymph nodes were slightly enlarged. Histopathological examination of the nasal cavity revealed a non-encapsulated, poorly delimited and ulcerated tumor composed of round cells arranged in a mantle supported by a discrete fibrovascular stroma extending the mucosa and lamina propria. Cells were round with sparse, eosinophilic and poorly delimited cytoplasm. Nuclei varied from round to elongated with condensed chromatin and evident nucleoli. Occasionally, aberrant nuclei, reniform shape and multinucleated cells were seen. Pleomorphism was moderate characterized by anisocytosis and anisocariosis. Typical and atypical mitosis were frequent (0-4 per field of highest magnification [400x]). Amidst the neoplasm, there were multifocal areas of necrosis and hemorrhage associated with a mild lymphocytic inflammatory infiltrate. Immunohistochemistry showed positive immunostaining for Vimentin antibodies and CD3, and negative for pan CK and CD20. Discussion: The lymphomas immunophenotyping is little used when it comes to farm animals, and there are few studies that use this technique for the definitive diagnosis of these neoplasms for small ruminants. The use of this technique must be considered in each case, in order to determine the pathogenesis, the accurate diagnosis and the origin of the neoplastic lymphocytes. In goats, T-cell lymphomas are the most diagnosed, although cases of multicentric B-cell lymphomas with ocular involvement have been diagnosed. In view of the clinical picture of the case described, infectious rhinitis already described in goats, such as aspergillosis and protothecosis, should be included as differential diagnoses. However, the anatomopathological findings facilitate the direction of the diagnosis, since infectious rhinitis presents as nodules / ulcerated masses or focal areas of necrosis associated with purulent secretion and in the histopathological examination it is possible to observe the intralesional etiological agents. In addition, the enzootic ethmoidal tumor must be included, as it has similar clinical signs and affects young animals, but they are adenomas/adenocarcinomas that affect the ethmoidal nasal shells induced by a retrovirus. Lymphomas in the caprine species are rare in the Northeastern semi-arid, but that in the present diagnostic routine occasionally occurs, being important the first description of its nasal shape for its inclusion in the differential diagnoses of diseases that present with clinical obstruction and dyspnea for the species.

Evaluating the influence of noise emitted by environmental enrichment equipment in routine farrowing management practices / Avaliação da influência do ruído ambiental emitido por enriquecimento físico e suínos em práticas de rotina exercidas na fase de maternidade

The installation of fans and rooftop sprinklers in swine housing and management facilities can increase noise intensity and may impair workers' hearing health over longs periods of time; therefore, an assessment of the piglets stress during invasive practices was made. This study set out to evaluate the noise intensity emitted by environmental enrichment devices (fans and rooftop sprinklers) and by piglets restrained for body temperature assessments and its effect on animal welfare and on the hearing health of workers exposed to it for long periods. Twenty piglets ranging in age from five to twenty days were observed. The sow gestation area was divided into a cooled (fans and rooftop sprinklers) and uncooled area. Two decibel meters were used to measure noise intensity, one for the general noise in the facilities and the other for the piglets, with five-minute intervals between assessments. Digital thermometers were used to take the rectal temperature, and infrared thermometers were used to take the body surface temperature. Fixed-effects ANOVA for the housing environment and periods and multiple comparisons at a significance level of 5% were applied. The average dorsal temperature of the piglets was 36 °C ± 1.2 in the cooled area and 38.4 °C ± 0.5 in the uncooled area. In both periods, the average maximum noise intensity was over 100 decibels. In the afternoon, the maximum in

A inserção de ventiladores e aspersores de água no telhado assim como o manejo de contenção de suínos podem aumentar a intensidade de ruídos dentro das instalações podendo, em longos exposições, prejudicar a saúde auditiva dos funcionários, permitindo a avaliação do estresse de leitões após práticas invasivas. O objetivo deste estudo foi estimar a intensidade do ruído emitido por enriquecimentos ambientais físicos (ventiladores e aspersores de água no telhado) e de leitões contidos para colheita da temperatura corporal e a influência dos ruídos emitidos na saúde auditiva de funcionários expostos por longos períodos e no bem-estar animal.  Vinte leitões machos e fêmeas foram utilizados, com idades entre cinco e 20 dias. A área de maternidade foi dividida em resfriada (ventiladores e aspersores de água no telhado) e área não resfriada. Para a análise da intensidade do ruído foram utilizados dois decibelímetros, sendo um para o ruído geral das instalações e um para os leitões, com cinco minutos de intervalo entre as análises. Para mensurar a temperatura retal foram utilizados termômetros digitais e para as temperaturas superficiais corporais termômetros infravermelhos. Utilizou-se ANOVA com efeito fixo de ambiente e período e comparação múltipla em 5%. A temperatura média do dorso dos leitões foi de 36 °C ± 1,2 na instalação refrigerada e 38,4 °C ± 0,5 no ambiente não refrigerado.

Bem-estar dos cães de abrigos municipais no estado do Paraná, Brasil, segundo o protocolo Shelter Quality / The welfare of dogs from municipal shelters in the state of Paraná, Brazil, under the Shelter Quality protocol

O bem-estar dos animais, além dos aspectos individuais, depende do entendimento e dedicação dos responsáveis pelo abrigo. O objetivo do presente trabalho foi avaliar o bem-estar dos cães mantidos em abrigos municipais do estado do Paraná, mediante a aplicação do protocolo Shelter Quality. Foram avaliados 16 abrigos, 439 cães e 165 recintos, na estação do outono de 2017. A maioria dos abrigos apresentou cães com condição corporal adequada e pelagem limpa, em recintos seguros, com metragem e suprimento de água adequados e conforto térmico. Além disso, a maioria dos cães eram mantidos em recintos coletivos e em ambientes abertos, com baixo nível de ruído e demonstravam mais emoções positivas, desejáveis na adoção. Como aspectos negativos, 58% (96/165) dos recintos avaliados tinham camas inadequadas ou inexistentes e 30% (50/165) dos recintos mantinham cães individualmente, sendo indicadores de baixo grau de bem-estar para os cães envolvidos. Além disso, nenhum abrigo disponibilizava ração para cães idosos e 81% (13/16) dos abrigos negligenciavam o diagnóstico e tratamento da dor. Apesar de a maioria dos abrigos apresentarem mais pontos positivos que negativos em sua avaliação, a gestão dos abrigos deve sempre visar à correção dos pontos críticos que comprometam o bem-estar dos animais.(AU)

Animal welfare, in addition to individual aspects, depends on the understanding and dedication of those responsible for the shelter. The objective of this study was to evaluate the welfare of dogs kept in municipal shelters in the state of Paraná, using the Shelter Quality protocol. A total of 16 shelters, 439 dogs and 165 enclosures were evaluated in the fall season of 2017. Most shelters presented dogs with adequate body condition and clean coat, in secure enclosures with adequate water supply and thermal comfort. In addition, most dogs were kept in collective enclosures and in open environments, with low noise levels and showing more positive, desirable emotions in adoption. As negative aspects, 58% (96/165) of the precincts evaluated had inadequate or inexistent beds and 30% (50/165) of the enclosures kept dogs individually, being indicators of a low degree of well-being for the dogs involved. In addition, no shelter provided elderly dog rations and 81% (13/16) of the shelters neglected the diagnosis and treatment of pain. Although most shelters present more positive than negative points in their evaluation, shelter management should always aim at correcting critical points that compromise animal welfare.(AU)

Lung-digit syndrome related to an adenosquamous feline lung carcinoma

Background: The lung-digit syndrome is a rare syndrome characterized by the presence of a primary pulmonar neoplasiamanifesting metastasis to the digit, occurring exclusively in felines. The diagnosis is based on the clinical signs, associatedwith radiographic and histopathological exams. There are no therapeutic protocols well-established, and surgical excisionis considered controversial due to high recurrence and metastasis rates. The prognosis is considered poor, with low survivalrates. The aim of this paper is to report a case of lung-digit syndrome attended in Rio de Janeiro.Case: A 12-year-old female cat, no defined race, was attend with the complaint of weight loss and injury in the right thoraciclimb, already having histopathological diagnosis of squamous differentiation adenocarcinoma through biopsy. Physicalexamination showed no other clinical signs at first, including no signs of respiratory disease. Laboratory and imaging examswere performed, and the radiographic examination showed alterations in the pulmonary parenchyma showing a nodulararea of increased radiographic density. Followed up by the manifestation of breathing noise at rest, as the first respiratorysigns. The association of the clinical evaluation, medical history, and histopathological report from the limb lesion, leadto the suspicion diagnostic of lung-digit syndrome. The owners decide for the palliative treatment with chemotherapy, using carboplatin and prednisolone. Only the first session was performed, with the animal being euthanized due to clinicalworsening 48 days after the initial manifestation of clinical signs. The diagnosis was confirmed...

The aim of this paper is to report a case of lung-digit syndrome attended in Rio de Janeiro.Case: A 12-year-old female cat, no defined race, was attend with the complaint of weight loss and injury in the right thoraciclimb, already having histopathological diagnosis of squamous differentiation adenocarcinoma through biopsy. Physicalexamination showed no other clinical signs at first, including no signs of respiratory disease. Laboratory and imaging examswere performed, and the radiographic examination showed alterations in the pulmonary parenchyma showing a nodulararea of increased radiographic density. Followed up by the manifestation of breathing noise at rest, as the first respiratorysigns. The association of the clinical evaluation, medical history, and histopathological report from the limb lesion, leadto the suspicion diagnostic of lung-digit syndrome. The owners decide for the palliative treatment with chemotherapy, using carboplatin and prednisolone. Only the first session was performed, with the animal being euthanized due to clinicalworsening 48 days after the initial manifestation of clinical signs. The diagnosis was confirmed...(AU)

Effect of traffic noise on Scinax nasicus advertisement call (Amphibia, Anura) / Efecto del ruído del tráfico en la vocalización de machos de Scinax nasicus (Amphibia, Anura)

El aumento de los sonidos de origen antropogénico, como los ruidos del tráfico, contribuyen a la contaminación acústica, que produce un efecto nocivo en el canto de los vertebrados. Comparamos la vocalización de machos de Scinax nasicus (Cope, 1862) en ambientes naturales (como referencia o control, Sitio A) y sitios afectados por ruidos de tráfico (Sitio B). La estructura de la vocalización se registró y amplificó en sonogramas (software Raven Pro 1.5). Se midieron siete variables de su vocalización: duración (s), número de notas, número de pulsos por nota, frecuencia máxima, mínima y dominante (kHz) y amplitud (dB). Además, en cada sitio se midió el ruido de fondo (frecuencia fundamental, la F0 y amplitud, dB). La amplitud del ruido de fondo alcanzó valores más altos (68.02 dB) en el Sitio B, en el Sitio A fue menor (34.81 dB). Por lo tanto, el F0 en el Sitio A fue de 6.28 kHz y en el Sitio B fue de 4.15 kHz. Las vocalizaciones de esta rana en el ambiente con ruido de tráfico (Sitio B) se caracterizaron por menor duración (s) y número de pulsos por nota, mayor amplitud (dB) y frecuencias máximas y dominantes más altas (kHz), baja frecuencia mínima en comparación con el ambiente control (Sitio A). Nuestro estudio resaltó que los machos de S. nasicus cambian su estructura vocal en estanques de ruido de tráfico, principalmente por ajuste vocal de sus frecuencias y amplitud para contrarrestar el efecto de enmascaramiento del ruido. Finalmente, el monitoreo acústico de anuros en ambientes ruidosos debe considerar el solapamiento espacial, temporal y espectral entre ruido acústico específico y el comportamiento de la especie.(AU)

Increased anthropogenic-made sounds such as traffic noises contribute to acoustic pollution, which produces deleterious effect on song-vertebrates. We compared the advertisement call of Scinax nasicus (Cope, 1862) males in natural (as a reference or control, Site A) and Sites affected by traffic noises (Site B). Call structure was recorded and it was amplified in sonograms (software Raven Pro 1.5). Seven variables were measured on its advertisement call: duration (s), number of notes, number of pulses per note, maximum and minimum frequency (kHz), dominant frequency (kHz) and amplitude (dB). In addition, at each Site the background noise (the fundamental frequency, F0 and amplitude, dB) was measured. The amplitude of background noise reached higher values (68.02 dB) in Site B, while in Site A was lower (34.81 dB). Thus, the F0 in Site A was 6.28 kHz and in Site B it was 4.15 kHz. Frog call in noisy environment (Site B) were characterized by lesser duration (s) and number of pulses per note, higher maximum and dominant frequencies (kHz), lower minimum frequencies, and amplitude (dB) when compared with control environment (Site A). Our study highlights, that S. nasicus males shift their vocal structure in traffic noisy ponds, mainly by vocal adjust of their frequencies and amplitude to counteract masking effect. Finally, acoustic monitoring of anurans on noise environments should be considering the spatial, temporal and spectral overlap between noise and species-specific acoustic behaviour.(AU)

ABSTRACT Increased anthropogenic-made sounds such as traffic noises contribute to acoustic pollution, which produces deleterious effect on song-vertebrates. We compared the advertisement call of Scinax nasicus (Cope, 1862) males in natural (as a reference or control, Site A) and Sites affected by traffic noises (Site B). Call structure was recorded and it was amplified in sonograms (software Raven Pro 1.5). Seven variables were measured on its advertisement call: duration (s), number of notes, number of pulses per note, maximum and minimum frequency (kHz), dominant frequency (kHz) and amplitude (dB). In addition, at each Site the background noise (the fundamental frequency, F0 and amplitude, dB) was measured. The amplitude of background noise reached higher values (68.02 dB) in Site B, while in Site A was lower (34.81 dB). Thus, the F0 in Site A was 6.28 kHz and in Site B it was 4.15 kHz. Frog call in noisy environment (Site B) were characterized by lesser duration (s) and number of pulses per note, higher maximum and dominant frequencies (kHz), lower minimum frequencies, and amplitude (dB) when compared with control environment (Site A). Our study highlights, that S. nasicus males shift their vocal structure in traffic noisy ponds, mainly by vocal adjust of their frequencies and amplitude to counteract masking effect. Finally, acoustic monitoring of anurans on noise environments should be considering the spatial, temporal and spectral overlap between noise and species-specific acoustic behaviour.

Whole body vibration in operators using agricultural soil preparation equipment / Alteração na vibração de corpo inteiro em operadores pela utilização de equipamentos agrícolas de preparo do solo

Agricultural tractors have been reported to exert negative effects on operator health. It is well known that when a farm machine is designed it must consider the human factors, to raise the safety levels and work quality. The aim of the present study was to estimate the degree of vibration transmissibility from the agricultural equipment used for the periodic soil preparation process and determine the exposure of the whole body of the operator to the vibration, incident to the agricultural tractor during the operation. A 4x2 TDA tractor was employed, coupled to the periodic soil preparation equipment. Five sets were used (tractor- disk plough, tractor-moldboard plow, tractor-offset disc harrow, tractor-rotary hoe, and tractor-scarifier) and the tractor without the equipment being coupled, at two tractor speeds of displacement (3.5 km.h-1 and 6.1 km.h-1). An index (IAVEA) was developed to assess whether the amplification or attenuation of the vibrations takes place on each orthogonal axis. The data were processed using the Noise Studio® software 6.95. Statistical evaluation was performed using the ASSISTAT version 7.7 beta program. After normality, the data were submitted to the analysis of variance by the F test; when significance was reported, the means were compared using the Tukey test, at 5% significance. The disk plow was the equipment that showed the greatest intensification of the vibrations in all the parameters estimated. All the sets assessed revealed statistically equal or higher values in terms of the tractor without the attached equipment. The IAVEA% was an index that enabled the quantification of the amplification or attenuation caused by the use of the agricultural equipment.(AU)

A utilização de tratores agrícolas tem causado efeitos negativos na saúde do operador. Faz-se necessário que no projeto de uma máquina agrícola sejam levados em consideração fatores humanos, para aumentar a segurança e melhorar a qualidade de trabalho. O objetivo do presente trabalho foi avaliar a transmissibilidade da vibração em equipamentos agrícolas de preparo periódico do solo devido a exposição a vibração de corpo inteiro incidente ao operador de trator agrícola durante a operação. O trator utilizado foi um trator 4x2 TDA acoplado a equipamentos de preparo periódico do solo. Foram utilizados cinco conjuntos (trator-arado de disco, trator-arado de aiveca, trator-grade off-set, trator-enxada rotativa, trator-escarificador) e um trator sem equipamento acoplado, em duas velocidades de deslocamento do trator (3,5 km.h-1 e 6,1 km.h-1). Foi desenvolvido um índice (IAVEA) para avaliar se ocorre amplificação ou atenuação das vibrações em cada eixo ortogonal. Os dados foram processados no software Noise Studio® 6.95. Para avaliação estatística foi utilizado o programa ASSISTAT versão 7.7 beta. Comprovada a normalidade, os dados foram submetidos à análise de variância pelo teste F e, quando significativas, as médias foram comparadas pelo teste de Tukey a 5% de significância. O arado de disco foi o equipamento que apresentou maior intensificação das vibrações em todos os parâmetros avaliados. Todos os conjuntos avaliados apresentam valores estatisticamente iguais ou superiores em relação ao trator sem equipamento acoplado. O IAVEA% se mostrou um índice capaz de quantificar a amplificação ou atenuação proporcionada pelo uso de equipamentos agrícolas.(AU)

Glossopharyngeal and vagus neuropathy associated to stylopharyngeus muscle compression in horse guttural pouch ­ case report / Neuropatia do glossofaringeo e vago associada à compressão pelo musculo estilofaringeo em bolsa gutural de equino ­ relato de caso

Neuropathies of pharyngeal branches of glossopharyngeal and vagus are often associated with guttural pouches diseases; however, these branches of injury due to stylopharyngeus muscle compression are not reported. A case was reported of a quarter horse mare, 8 years old, 450 kg, presenting dyspnea and respiratory noise associated with weight loss. Clinical examination observed mixed dyspnea, tachycardia, dysphagia, sialorrhea, lung crackles and submandibular and parotid lymphadenopathy. Endoscopic exam showed right arytenoid chondritis, nasopharyngeal collapse, generalized larynx edema and dorsal displacement of the soft palate. Right guttural pouch evaluation showed swelling in the origin of stylopharyngeus muscle with consequent compression of the XII, X and IX cranial nerves. Tracheotomy, systemic treatment with corticosteroids, beta lactams and aminoglycosides antibiotics were performed. No resolution was observed and, after 16 days, the animal showed clinical worsening, developed pleuropneumonia, uveitis, severe sepsis, acute renal failure and was euthanized. The mixed neuropathy resulted in rapid clinical deterioration of the animal, due to the difficulty in swallowing and consequent associated respiratory processes. This report emphasizes the importance of evaluating stylopharyngeus muscle origin in cases of nasopharyngeal collapse associated with dysphagia in horses, given the possibility that structural changes in this muscle can result in laryngeal neuropathy.(AU)

As neuropatias do glossofaríngeo e vago são frequentemente associadas com enfermidade das bolsas guturais. A ocorrência desta lesão secundária a compressão pelo músculo estilofaríngeo não é reportada. Relata-se o caso de uma égua quarto de milha, 8 anos de idade, 450 kg, apresentando dispneia, ruído respiratório e perda de peso. No exame clínico observou-se dispnéia mista, taquicardia, disfagia, sialorréia, crepitação pulmonar e linfadenopatia submandibular e parotídea. Ao exame endoscópico identificou-se condrite aritenóide direita, colapso nasofaríngeo, edema generalizado da laringe e deslocamento dorsal do palato mole. Na avaliação da bolsa gutural direita identificou-se aumento de volume na origem do músculo estilofaríngeo com consequente compressão dos nervos cranianos XII, X e IX. Foi realizada traqueotomia, tratamento sistêmico com corticosteróides e antibióticos. Nenhuma resolução foi observada, após 16 dias o animal apresentou piora clínica, pleuropneumonia, uveíte, sepse grave, insuficiência renal aguda e foi submetido à eutanásia. A neuropatia mista resultou em rápida deterioração clínica do animal, devido à dificuldade de deglutição e processos respiratórios associados. Salienta-se a importância de se avaliar a origem do músculo estilofaríngeo em casos de colapso nasofaríngeo associado a disfagia em cavalos, dada a possibilidade de que alterações estruturais nesse músculo possam resultar em neuropatia laríngea.(AU)
