Abstract Objective: To investigate the effects of different physical exercise programs and polymorphisms of the FTO (fat mass and obesity-associated gene) on body composition and cardiovascular risk factors in adolescents with overweight and obesity. Methods: A randomized, parallel, double-blind clinical trial consisting of the adolescent overweight from the state public network, in a simple representative random sample, who participated in an aerobic exercise or weight training intervention for 10 weeks. Anthropometry, body composition, biochemical markers, sexual maturation, and rs9939609 polymorphism in the FTO gene were assessed. 347 adolescents had their characterization of nutritional status. 72 individuals with overweight and obesity were invited to participate. 39 remained for the start of the program and were randomly allocated to both types of intervention. In the end, 26 subjects participated in the intervention programs, with 12 and 14 in the aerobic and weight training programs, respectively. Results: Heterozygous and homozygous bearers of risk allele A participating in the aerobic program showed improvements in glycemia (p = 0.002) and total cholesterol (p = 0.023) and a reduction in body fat mass (p = 0.041). The weight training program reduced glycemia in patients with the risk allele A (p = 0.027). Cameron’s stage four sexual maturation participants were 2.1 times more likely to improve their body fat (CI = 1.31–3.39). Conclusion: Aerobic exercises produced exclusively a significant decrease in fat mass and total cholesterol in patients with risk allele A. Distinct physical exercise programs may cause diverse changes in risk variables related to the health of adolescents.

The problem of improper disposal of polymeric waste is increasingly in present. Thus, the use of biodegradable polymers is a good alternative, especially for packaging. Compostable and biodegradable polymers such as PHBV can be completely degraded, making them ideal. But the short processability window and fluid instability is an important drawback to the wider application of this polymer in pure form. Production of composite materials has been indicated as a possibility for using this polymer. One source of filler is cellulose, because besides being widely available from agroindustrial waste. In this context, the present work reports the formulation of rigid packaging with PHBV and cellulose waste. An analytical mill was used to promote the dispersion of cellulose fibers. In general, the cellulose fibers increased the Vicat softening point of the polymeric matrix. There were more crystalline structures, according to DSC, and a decrease in impact strength, probably due to increased crystallinity and agglomerate formation. The microscopic analysis indicated greater surface roughness of the composite due to the increase of fibers, resulting in increased contact angle.

Abstract Cultivation of species of the genus Eucalyptus is important for the Brazilian economy, with 6.97 million hectares planted. Glycaspis brimblecombei Moore (Hemiptera: Aphalaridae), detected in Brazil in 2003, has dispersed and now damages Eucalyptus crops in all regions of this country. The location and identification of entomopathogenic fungi isolates may increase the options for integrated pest management. The objective of this research was to evaluate the pathogenicity of Cordyceps cateniannulata and Cordyceps javanica isolates to G. brimblecombei. Ten nymphs of G. brimblecombei, with or without lerps, were placed per Eucalyptus leaf cut with one of its edges on hydroretentive gel inside Petri dishes. The fungi isolates were suspended in a solution of Tween 80 (0.1%) at the concentration of 1.0 x 108 conidia mL-1 and sprayed on the G. brimblecombei nymphs. The mortality of this insect was evaluated daily for seven days, and the dead individuals were transferred to humid chambers. The conidia viability of the isolates was greater than 93%. The mortality of G. brimblecombei nymphs, seven days after the application of the fungi, was 100%. This is the first report of the pathogenicity of C. cateniannulata and C. javanica isolates, occurring naturally in the field, to G. brimblecombei.

RESUMO Introdução: Cuidar completamente das crianças com microcefalia é um grande desafio para os seus cuidadores. A situação de vulnerabilidade social aliada à complexidade do cuidado pode levar à sobrecarga com perda de qualidade de vida. Objetivo: Analisar a relação entre aspectos socioeconómicos, domínio social da qualidade de vida e sobrecarga de mães cuidadoras de crianças com microcefalia. Metodologia: Estudo transversal com 105 participantes, por meio da aplicação de questionários sociodemográficos, WHOQOL-BREF, sobrecarga do cuidador. Foram utilizados os testes ANOVA, t de Student, e coeficiente de correlação de Pearson (r). Resultados: População de mães pardas (65.7%), desempregadas (88.6%), dependentes de benefícios sociais (76.2%), baixa escolaridade (50.5%) e insuficiência financeira (90.5%). A média do domínio social foi considerada baixa (51.11). Houve associação entre benefício social e pontuação total de qualidade de vida (p=0.046).

Foi encontrada associação entre os níveis de sobrecarga e as variáveis de etnia (p= 0.027), ocupação (p= 0.043) e meio de transporte (p <0.0001). A sobrecarga tem um impacto negativo na qualidade de vida (r= -.463, p <0.0001), percepção de qualidade de vida (r= -.476, p= <0.0001), qualidade de vida total (r= -.576, p= <0.0010). Conclusões: As mães cuidadoras sofrem sobrecarga com perda de qualidade de vida. Os aspectos sociais influenciam diretamente e podem potenciar a sobrecarga do cuidado. A enfermagem tem um papel fundamental na criação e implementação de linhas de cuidados com ênfase na promoção da saúde e no alívio da sobrecarga do cuidador.

ABSTRACT Introduction: Taking care of children with microcephaly is a great challenge for their care providers because of the associated social vulnerability, work overload, and loss of quality of life. Objective: To analyze the associations related to the social aspects, the quality of life, and the work overload among care providing mothers of children with microcephaly. Methodology: This is a transversal study with 105 participants. Social and demographic questionnaires and WHOQOL-BREF were used. ANOVA tests, Student’s t-test, and Pearson’s correlation coefficient were calculated. Results: 65.7% were of mixed ethnicity; 88.6% were unemployed; 76.2% were dependent on Social Welfare; 50.5% had a low level of education; and 90.5% were financially insufficient. The social domain average was considered low (51.11). An association was found between social benefits and quality of life (p=0.046). 39% of these mothers suffer from severe work overload while 30.4% suffer from intense work overload. An association was found between the levels of work overload and ethnicity (p= 0.027), occupation (p= 0.043), and transportation means (p <0.0001). Work overload had a negative impact on the quality of life (r= -.463, p <0.0001), the perception of quality of life (r= -.476, p= <0.0001), and total quality of life (r= -.576, p= <0.0010). Conclusions: These care providing mothers suffer work overload with an associated loss of quality of life. Social aspects have a direct influence and can increase work overload. Nursing professionals have a fundamental role in the creation and implementation of attention initiatives aimed at promoting health and relief to this kind of care providing mothers.

RESUMO Cicatrização de ferida é um processo dinâmico, que tem por objetivo restaurar a continuidade do tecido lesionado. No entanto, em alguns casos, é necessário favorecer condições adequadas para viabilizar o processo fisiológico. Neste estudo foram utilizados ratos Wistar, divididos aleatoriamente entre cinco grupos, com 12 animais cada, sendo eles: grupo P (Bidens pilosa L.), grupo mel, grupo Co1 (pomada comercial alopática), grupo Co2 (pomada comercial homeopática) e grupo CT (controle). As lesões foram geradas por incisão com punch de 8mm, sendo tratadas diariamente de forma tópica. Foram eutanasiados quatro animais por grupo, no terceiro, sétimo e 14º dias do experimento, e o material coletado foi armazenado em formalina 10% e encaminhado para processamento histológico. Posteriormente, realizou-se a contagem de leucócitos mononucleares, fibroblastos e neovasos e avaliou-se a arquitetura de fibras colágenas. Os resultados da contagem foram analisados pela ANOVA, seguida pelo teste de Tukey (P<0,05). O modelo experimental proposto neste estudo demonstrou que todos os tratamentos apresentaram potencial cicatrizante, com exceção do mel. A aplicação tópica do creme do extrato de Bidens pilosa L. a 10% apresentou melhor perfil anti-inflamatório; a pomada alopática apresentou boa aderência à superfície da lesão e a pomada homeopática, grande potencial angiogênico, com menor tempo de cicatrização.

ABSTRACT Wound healing is a dynamic process that aims to restore the continuity of injured tissue. However, in some cases it is necessary to favor adequate conditions to enable the physiological process. Wistar rats were randomly divided into 5 groups with 12 animals each, namely: group P (Bidens pilosa L.), group honey, group Co1 (commercial allopathic ointment), group Co2 (commercial homeopathic ointment) and group CT (control). The lesions were generated by an 8mm punch incision and were treated topically daily. Four animals per group were euthanized on the 3rd, 7th and 14th day of the experiment and the collected material was stored in 10% formalin and sent for histological processing, after which mononuclear, fibroblasts and neovascular leukocytes were counted and collagen fiber architecture was evaluated. Counting results were analyzed by ANOVA, followed by Tukey test (p <0.05). The experimental model proposed in this study showed that all treatments had healing potential, except honey. The topical application of 10% Bidens pilosa L. extract cream showed the best anti-inflammatory profile; Allopathic ointment showed good adhesion to the surface of the lesion and homeopathic ointment showed great angiogenic potential with shorter healing time.

RESUMO Avaliou-se a produção de calor corporal de vacas F1 HxZ manejadas em diferentes microclimas. Foram avaliadas 48 vacas, divididas em três grupos, manejadas em pastos e microclimas diferentes. Cada grupo foi subdividido em três grupos de suplementação fornecida durante a ordenha. Os registros termográficos dos flancos direito e esquerdo ocorreram com os animais a pasto. As temperaturas do olho e retal foram mensuradas após a ordenha. O ITGU caracterizou sinal de perigo para o microclima 1 no período da tarde (81,7) e para o microclima 2 nos turnos da manhã e da tarde (81,6 e 83,8, respectivamente). No microclima 2, houve diferença da temperatura do flanco direito para animais do grupo 2 em relação aos animais do grupo 3. A temperatura do flanco esquerdo foi superior para os animais do grupo 1. O microclima 1 foi caracterizado de conforto térmico, e o 2 de desconforto nos períodos da manhã e da tarde. A suplementação não influenciou na produção de calor dos animais. As médias da temperatura retal e do olho não diferiram entre os grupos, e a correlação apresentou valores baixos e moderados para os microclimas 1 e 2, respectivamente. A oferta de diferentes fontes de suplementação não interfere na produção de calor corporal de vacas F1 HxZ, mesmo quando fornecido em ambiente climático em que o ITGU é próximo a 84.

ABSTRACT Body heat production of F1 HxZ cows managed in different microclimates was evaluated. We evaluated 48 cows, divided into two groups, managed in different pastures and microclimates. Each group was subdivided into three groups of supplementation provided during milking. The thermographic records of the right and left flanks occurred with the animals on the grass. Eye and rectal temperatures were measured after milking. The BGT had a danger signal for microclimate 1 in the afternoon (81.7) and microclimate 2 in the morning and afternoon shifts (81.6 and 83.8, respectively). In microclimate 2, there was difference in the temperature of the right flank for animals in group 2 in relation to the animals in group 3. The temperature of the left flank was higher for the animals in the group 1. Microclimate 1 was characterized by thermal comfort and 2 was discomfort in the morning and afternoon. Supplementation did not influence the heat production of the animals. Rectal and eye mean averages did not differ between groups and the correlation presented low and moderate values for microclimate 1 and 2, respectively. The supply of different sources of supplementation does not interfere with the production and body heat of F1 HxZ cows even when supplied in a climatic environment in which the BGT is close to 84.

RESUMO: A indução do parto visa concentrar os nascimentos para melhor acompanhamento das parturientes e primeiros cuidados aos neonatos. Contudo, mesmo que a técnica de indução de parto, com administração de dexametasona, tenha sido descrita com sucesso desde o final da década de 70, existem estudos escassos que relatam a influência desta técnica sobre o parto em ovinos da raça Santa Inês. Dessa forma, o objetivo do estudo foi avaliar a eficácia da dexametasona em duas doses (8 e 16mg), para a indução do parto de ovelhas Santa Inês com 145 dias de gestação e avaliar os seus efeitos nas características de desencadeamento e finalização do parto. Para este estudo foram utilizadas 58 ovelhas, criadas em sistema extensivo nas fazendas experimentais da UFBA, com prenhez confirmada após inseminação artificial em tempo fixo ou monta controlada. Essas fêmeas foram separadas em três grupos, de acordo com a dose de dexametasona administrada (G1 = 0mg, G2 = 8mg e G3 = 16mg). Destes partos nasceram 79 cordeiros. Foram avaliados o período em horas da indução do parto aos nascimentos, a apresentação fetal ao nascimento, assim como o peso da placenta e o período para o delivramento. Os dados foram analisados pelo pacote estatístico Statistical Analysis System (SAS v.9.0®, 2002) sendo considerado para todas as análises o nível de significância de 5%. Os nascimentos dos grupos induzidos ocorreram em média com 48,4±22,1 horas após a indução, enquanto que as fêmeas com parto não induzido pariram em média 131,96±41,9 horas após aplicação do placebo (P<0,05), confirmando a eficácia de ambas as doses para indução do parto. O período da indução até o parto não diferiu (P>0,05) entre as doses utilizadas. Não ocorreram diferenças no parto em relação à estática fetal, tempo para o delivramento e peso da placenta nos diferentes grupos. Com este estudo, conclui-se que a indução de parto em ovelhas aos 145 dias de gestação com oito e 16 mg de dexametasona é uma técnica eficaz e que não altera o trabalho de parto nas ovelhas da raça Santa Inês.

ABSTRACT: The induction of labor aims to concentrate births to follow up better the parturient and the first care to the neonates. However, even if the labor induction technique with dexamethasone administration has been successfully described since the late 1970s, few studies report the technique of birth development and neonatal vitality in Santa Inês sheep. This study aimed to evaluate the efficiency of dexamethasone use in two doses (8 and 16mg) in labor induction of Santa Inês ewes at 145 days of gestation and to evaluate its effects on the birth characteristics. In this study, 58 ewes were used, raised in an extensive system in the experimental farms of UFBA, with confirmation pregnancy after fixed-time artificial insemination or controlled breeding. These female ewes were separated into three groups according to the dose of dexamethasone administered (G1 = 0mg, G2 = 8mg, and G3 = 16mg). From these births, 79 lambs were born. This study analyzed the period from induction of labor to birth, fetal presentation at birth, the weight of the placenta, and the period for placenta expulsion. The data were analyzed by the Statistical Analysis System (SAS v.9.1.3®, 2002), and the significance level considered for all analyzes was 5%. Births of induced groups occurred on average at 48.4±22.17 hours after induction, while the females with non-induced labor gave birth 131.96±41.9 hours on average after the placebo application (P<0.05), confirming the efficiency of both doses for induction of labor. The period from induction to birth did not differ (P>0.05) between the doses used. There were no differences in delivery about the fetal static relation, time to placental attachment, and weight. With this study, it can be concluded that the induction at 145 days of gestation with eight or 16mg of dexamethasone is a useful technique and does not alter the labor in Santa Inês sheep.

Abstract Periodontal disease is considered the main oral cavity disorder in dogs. Essential oils have the potential for use in the prevention and treatment of oral diseases. The antimicrobial activity of Schinus molle L. essential oil (SMEO) has already been reported. Chitosan, a natural product with antimicrobial activity and good biocompatibility has potential in biodental applications. In this study, we evaluated the in vitro antimicrobial activity of SMEO against bacteria associated with periodontal disease in dogs, developed and evaluated the physicochemical properties of a novel chitosan-based buccal delivery system containing SMEO. SMEO showed antimicrobial activity against Gram positive and Gram negative bacteria associated with canine periodontitis, with MIC values of 750 µg.mL-1 for Staphylococcus spp. and Streptococcus spp, 1000 µg.mL-1 for Corynebacterium spp. and 1250 µg.mL-1 for Pseudomonas spp. All formulations evaluated presented adequate physicochemical properties, good stability, and pH values close to buccal pH (5.0–7.0). Chitosan gel loaded with SMEO showed potential as a SMEO delivery system, having the ideal physicochemical and rheological properties (pseudoplastic and apparent viscosities) required for application on buccal tissue. Thus, we can conclude that formulation has the potential to be used for buccal mucosa delivery in the prevention and treatment of periodontal disease in dogs.

Malnutrition is still considered endemic in many developing countries. Malnutrition-enteric infections may cause lasting deleterious effects on lipid metabolism, especially in children living in poor settings. The regional basic diet (RBD), produced to mimic the Brazilian northeastern dietary characteristics (rich in carbohydrate and low in protein) has been used in experimental malnutrition models, but few studies have explored the effect of chronic RBD on liver function, a central organ involved in cholesterol metabolism. This study aimed to investigate whether RBD leads to liver inflammatory changes and altered reverse cholesterol metabolism in C57BL6/J mice compared to the control group, receiving a standard chow diet. To evaluate liver inflammation, ionized calcium-binding adapter protein-1 (IBA-1) positive cell counting, interleukin (IL)-1β immunohistochemistry, and tumor necrosis factor (TNF)-α and IL-10 transcription levels were analyzed. In addition, we assessed reverse cholesterol transport by measuring liver apolipoprotein (Apo)E, ApoA-I, and lecithin-cholesterol acyltransferase (LCAT) by RT-PCR. Furthermore, serum alanine aminotransferase (ALT) was measured to assess liver function. RBD markedly impaired body weight gain compared with the control group (P<0.05). Higher hepatic TNF-α (P<0.0001) and IL-10 (P=0.001) mRNA levels were found in RBD-challenged mice, although without detectable non-alcoholic fatty liver disease. Marked IBA-1 immunolabeling and increased number of positive-IBA-1 cells were found in the undernourished group. No statistical difference in serum ALT was found. There was also a significant increase in ApoA mRNA expression in the undernourished group, but not ApoE and LCAT, compared with the control. Altogether our findings suggested that chronic RBD-induced malnutrition leads to liver inflammation with increased ApoA-I activity.

Abstract Chronic stress exposure commonly increases adrenals weight and changes their morphology. This study aimed to compare four methods to delimitate the cortical and medullary layers of adrenals glands in Nelore bulls. Fresh adrenals did not present differentiation between layers. Then, frozen adrenals were distributed in plastics bags with fixative Bouin (G1), 96ºGL ethylic alcohol (G2), 10% formaldehyde (G3), or 2.5% glutaraldehyde (G4). After 12 hours of fixation, the G1 adrenal glands did not show the entire cortical layer marked by Bouin’s solution. For G2 and G3 there was a poor contrast, while for G4 there was a reasonable contrast. After 24 hours of fixation, G1 had an excellent contrast between layers, while G2 and G4 had a reasonable contrast and G3 a very bad contrast. After 48 hours it was difficult to differentiate cortical and medullar layers for G1; for Group 2 we get a reasonable contrast; and for G3 the contrast was bad. For G4 the contrast was not as sharp due to the medulla became dark. It was concluded that fixation of adrenals must be done in Bouin’s solution for 24 hours to obtain an effective evaluation of the adrenals’ morphometry.

RESUMO: Saimiri sciureus é uma espécie de primata neotropical muito utilizada como animal de pesquisa. No entanto ainda há dificuldades em biotérios quanto a sua reprodução devido à alta ocorrência de distocia. A distocia em primatas pode ter origem devido à desproporção cefalopélvica, sendo que em macacos-de-cheiro é relatada a gestação de fetos grandes. O presente trabalho descreve dados de pelvimetria em espécimes de macaco-de-cheiro, fêmeas adultas e subadultas provenientes de uma colônia de pesquisa do Pará, Brasil. Foram realizadas radiografias da pelve em projeção ventrodorsal e por meio destas mensurados os diâmetros biilíaco superior (DBIS); diâmetro biíliaco inferior (DBII); diâmetro biilíaco médio (DBIM); diâmetro diagonal direito (DDD); diâmetro diagonal esquerdo (DDE); diâmetro sacro-púbico (DSP); com base nos diâmetros obtidos também foi calculada a área de entrada da pelve (AEP). Os valores médios dos diâmetros pélvicos e da AEP em fêmeas adultas foram: DBIS 1,714cm, DBIM 1,957cm, DBII 1,686cm, DDD 2,771cm, DDE 2,764cm, DSP 2,543cm e AEP 3,9056cm2; e para fêmeas subadultas: 1,588cm DBIS, 1,850cm DBIM, 1,625cm DBII, 2,50cm DDD, 2,474cm DDE, 1,95cm DSP e 2,8293 cm2 AEP. Observou-se que a pelve de Saimiri sciureus é dolicopélvica. Houve diferença estatística significativa entre os valores para fêmeas adultas e subadultas para DBIS, DBIM, DDD, DDE, DSP e AEP. Em comparação com dados da literatura de pelvimetria para S. sciureus observaram-se menores valores de DBIS e DBII. O resultado deste trabalho servirá como base para futuros estudos utilizando-se mensurações pélvicas e predição de distocia em primatas neotropicais e referência para comparação entre S. sciureus de diferentes biotérios.

ABSTRACT: Saimiri sciureus is a neotropical primate widely used in research. However, there are still difficulties regarding their reproduction in vivaria due to the high incidence of dystocia. Dystocia in primates can be caused by cephalopelvic disproportion and in Squirrel Monkeys, pregnancy of large fetuses were reported. This paper describes pelvimetry data of adult females and subadults in specimens of Squirrel Monkeys, from a research colony of Para, Brazil. Pelvic radiographs were obtained in ventrodorsal projections and the following measurements were taken: superior bi-iliac diameter (SBID); inferior bi-iliac diameter (IBID); bi-iliac average diameter (BIAD); right diagonal diameter (RDD); left diagonal diameter (LDD); sacro-pubic diameter (SPD); Based on the obtained diameters, the entrance area of the pelvis (EAP) was also calculated. The average values of the pelvic diameters and EAP in adult females were SBID 1.714cm, BIAD 1.957cm, IBID 1.686cm, RDD 2.771cm, LDD 2.764cm, SPD 2.543cm and EAP 3.9056cm2; and subadult females: 1.588cm SBID, 1.850cm BIAD, 1.625cm IBID, 2.50cm RDD, LDD 2.474cm, 1.95cm SPD and 2.8293 cm2 EAP. Saimiri sciureus pelvis is characterized as dolichopelvic. There was statistical significance between the values for adult females and subadults to SBID, BIAD, RDD, LDD, SPD and EAP. The values of SBID and IBID were lower when compared to the published data for the same species. The result found on this paper will serve as a basis for future studies using pelvic measurements and dystocia prediction of neotropical primates and comparison between different vivaria.

RESUMO O ciclo silvestre da raiva constitui um sério desafio para a vigilância epidemiológica no controle da doença nos animais domésticos, de companhia ou de produção, e nos seres humanos. O entendimento sobre a circulação do vírus rábico no ambiente natural é cada vez mais importante, em razão da constância de reservatórios naturais da doença e da presença de vetores potenciais da infecção aos humanos e aos animais domésticos. Com o objetivo de avaliar a ocorrência da raiva no estado de Sergipe, foram analisados 935 morcegos hematófagos (Desmodus rotundus), 46 cachorros-do-mato (Cerdocyon thous) e 24 primatas (Callithrix spp.) no período de 1987 a 2014, dos quais resultaram positivos um morcego, 17 cachorros-do-mato e nenhum primata. Em que pese a contundente falta de resultados positivos em morcegos hematófagos, principal vetor da raiva dos herbívoros, mais estudos são necessários no monitoramento dos casos, pois o estado, do ponto de vista epidemiológico, é endêmico para a raiva dos herbívoros. A vigilância epidemiológica do vírus da raiva nos animais silvestres é primordial para o sucesso dos programas de controle da doença em rebanhos de animais domésticos e em seres humanos.

ABSTRACT The wild cycle of rabies constitutes a serious challenge to epidemiological surveillance for disease control in domestic, companion or production animals, and in humans. The understanding of rabies virus circulation in the natural environment is increasingly important due to the constancy of natural reservoirs of the disease and the presence of potential vectors of the infection to humans and domestic animals. Aiming to evaluate the occurrence of rabies in the State of Sergipe a total of 935 hematophagous bats (Desmodus rotundus), 46 wild dogs (Cerdocyon thous) and 24 primates (Callithrix spp.) were analyzed from 1987 to 2014, of which 1 bat, 17 crab-eating foxes and no primates were positive. Due to the lack of positive results in hematophagous bats, the main vector of herbivorous rabies, more studies are needed to monitor cases, because from an epidemiological point of view, Sergipe is endemic for herbivorous rabies. Epidemiological surveillance of rabies virus in wild animals is primordial for the success of disease control programs in herds of domestic animals and humans.

RESUMO O presente trabalho teve como objetivo avaliar se contatos extradurais durante hemilaminectomia em cães com extrusão de disco intervertebral causariam piora neurológica no pós-operatório imadiato e/ou tardio. Dezenove cães com extrusão toracolombar de disco intervertebral foram submetidos à hemilaminectomia para descompressão medular e remoção do material extruso. Durante o procedimento cirúrgico, os contatos meningomedulares foram quantificados. Antes da cirurgia, 11/19 cães apresentavam paraplegia (com nocicepção) e 8/19 cães, paraparesia. Ao fim do estudo, apenas dois cães (2/19) mostravam paraplegia com dor profunda e um (1/19), paraparesia. Observou-se maior quantidade de contatos extradurais quando o material discal extruso encontrava-se em posição ventrolateral. Os contatos extradurais não mostraram influência estatística na evolução neurológica dos animais, bem como no tempo de recuperação das funções motora. Vinte e quatro e 48 horas após a cirurgia, 13/19 cães apresentavam o mesmo grau neurológico de antes da cirurgia. Após sete e 90 dias de pós-operatório, 13/19 e 17/19 demonstraram melhora neurológica em comparação com o pré-operatório, respectivamente. A quantidade de contatos extradurais não influenciou na recuperação neurológica dos cães. Esses achados indicam que uma inspeção minuciosa do canal vertebral pode ser recomendada, a fim de remover o máximo de material discal extruso, evitando-se piora neurológica por compressão medular.

ABSTRACT The objective of the present study was to evaluate if extradural contact during hemilaminectomy would cause neurological deterioration in the early and/or late postoperative period in dogs with intervertebral disc extrusion. Nineteen dogs with thoracolumbar intervertebral disc extrusion underwent hemilaminectomy for spinal cord decompression and removal of extruded disc material. Meningeal contacts during surgery were quantified. Paraplegia (with nociception) and paraparesis were observed in 11/19 and 8/19 of dogs, respectively, before surgery. At the end of our study, only two (2/19) had paraplegia and one (1/19), paraparesis. There were more extradural contacts when extruded intervertebral disc material was at a ventrolateral position. Extradural contacts during surgery had no influence on neurological progression nor on time to recovery of motor function. Immediately (24 and 48 hours) after surgery, 13/19 dogs had the same neurological stage before surgery. At 7 and 90 days, 13/19 and 17/19 dogs, respectively, showed neurological improvement, compared with their preoperative stage. There was no influence of the number of extradural contacts on neurological recovery. These findings indicate that a careful inspection of the vertebral canal for removal of as much extruded disc material as possible does not cause neurologic deterioration.

RESUMO Objetivou-se com o presente trabalho relatar um caso de mieloma múltiplo (MM) em uma cadela com apresentação clínica atípica de rigidez da musculatura facial. Foram realizados hemogramas seriados, exames bioquímicos, sumário de urina, sorologia para leishmaniose, radiografias de crânio, citologia de medula óssea e eletroforese de proteínas séricas. O infiltrado plasmocitário em medula óssea >20%, a gamopatia monoclonal e as lesões compatíveis com lise óssea, observados no mielograma, eletroforese de proteínas e exame radiográfico, respectivamente, foram determinantes para conclusão diagnóstica de MM. A doença pode ter uma apresentação clínica variável em cães e representar um desafio ao diagnóstico na clínica de animais de companhia, principalmente em áreas endêmicas de doenças infecciosas que se manifestam com apresentações clínicas e laboratoriais semelhantes.

ABSTRACT This paper reports a case of multiple myeloma (MM) in a bitch with atypical clinical presentation of rigidity of the facial muscles. Hemogram, biochemical tests, urinalysis, serology for leishmaniasis, skull radiography, bone marrow cytology and serum protein electrophoresis were performed. The plasma cell infiltration in bone marrow was >20 %, the monoclonal gammopathy and lesions compatible with bone lysis observed in the myelogram, protein electrophoresis and radiographic examination respectively, were decisive for diagnostic conclusion of MM. The disease may have a variable clinical presentation in dogs and pose a challenge for diagnosis in the pet clinic, especially in endemic areas of infectious diseases that present with similar clinical and laboratory presentations.
