RESUMO

We describe an outbreak of leishmaniasis in seven guinea pigs (Cavia porcellus) in which nodular ulcerated skin lesions of varying sizes were observed in the nasal cavity, upper lip, pinnae, vulva, and periarticular region of the limbs. Cytologic exam of collected samples of the lesions in the auricle of one of the animals revealed macrophages containing parasitophorous vacuoles of approximately 4.0μm in diameter in their cytoplasm with morphology suggestive of Leishmania sp. Although skin lesions spontaneously regressed in two of the Guinea pigs, only one survived. All six animals that died were necropsied. Grossly, all animals showed bloody nodular cutaneous lesions with crusts. One of the guinea pigs had distended dark red and firm lungs. Histopathology of the skin lesions revealed histiocytic interstitial acanthotic dermatitis associated with a myriad of Leishmania organisms within macrophages cytoplasm. In the lung, the lesions were characteristic of broncho-interstitial pneumonia with focal infiltrates of neutrophils, epithelioid macrophages, and multinucleated giant cells containing 2µm basophilic amastigotes with morphology compatible with Leishmania spp. A focal granulomatous lesion ,associated with the causal agent in the lung is a novel description of leishmaniasis in guinea pigs caused by L. enriettii. The polymerase chain reaction (PCR) technique with mini-exon primer performed in samples of lesions from two affected guinea pigs was positive and equal to the reference strain, identifying Leishmania enriettii. The cytological, macroscopic, and histological lesions associated with the PCR technique allowed the diagnosis of leishmaniasis and the identification of the specie L. enriettii.


Descrevemos um surto de leishmaniose em sete cobaias (Cavia porcellus), com lesões cutâneas nodulares ulceradas de tamanhos variados observadas na cavidade nasal, lábio superior, pavilhões auriculares, vulva e região periarticular dos membros. No exame citológico foram encontrados macrófagos contendo vacúolos parasitóforos no citoplasma de aproximadamente 4.0μm em diâmetro com morfologia sugestiva de Leishmania sp. Apesar de regressão espontânea das lesões cutâneas terem ocorrido em duas das sete cobaias, apenas um sobreviveu. Seis dos sete animais afetados morreram e foram necropsiados. Macroscopicamente, todos os animais apresentaram lesões cutâneas nodulares, crostosas e sanguinolentas. Uma das cobaias tinha pulmões vermelho-escuros, distendidos e firmes. A histopatologia das lesões cutâneas revelou dermatite acantótica intersticial histiocítica associada a miríades de organismos de Leishmania no citoplasma de macrófagos. Nos pulmões as lesões eram características de pneumonia bronco-intersticial com infiltrado focal de neutrófilos, eosinófilos, macrófagos epitelioides e células gigantes multinucleadas contendo amastigotas basofílicos de 2µm com morfologia compatível com Leishmania spp. Lesões granulomatosas focais associadas ao agente no pulmão são um achado inédito na leishmaniose causada por L. enriettii em cobaias. A técnica de reação em cadeia da polimerase (PCR) com primer mini-exon realizada em amostras de lesões de duas cobaias afetadas foi positiva, identificando Leishmania enriettii. Os aspectos macroscópicos, citológicos, e histológicos associados à técnica da (PCR), permitiram o diagnóstico da leishmaniose e a identificação da espécie L. enriettii.

RESUMO

Background: Gout, a metabolic disease affecting multiple species, is frequent in birds which are uricotelic animals. It is primarily caused by hyperuricemia originating from birds' renal disorders with subsequent deposition of urate crystals into tissue. The location of the crystals determines the type of disease. Joint disease occurs with deposition inside and around joints, joint capsules, and tandine hems, while visceral disease occurs when the serous surface of visceral organs (mainly pericardium, liver, kidneys, air sacs, peritoneum, and spleen) are affected. This report describes a case of visceral uric gout in a Muscovy duck, which is rare. Case: An adult, male, Muscovy duck (Cairina moschata), kept under human care in a zoo, was referred to a veterinary clinic. The animal presented suddenly with prostration, ataxia, and anorexia, and died the following day. The body was sent to the Pathology Sector of Ritter dos Reis University Center (UniRitter) for a necropsy. During the necropsy, it was observed that white membranes, presenting a "chalk dust" appearance, were deposited under the serous layer of organs including the liver, kidneys, and pericardium. Following the necropsy and macroscopic evaluations, fragments of multiple organs were fixed in 10% formalin and processed routinely with hematoxylin and eosin (HE) staining for histopathological evaluation in an analysis laboratory in Porto Alegre city. A deposition of amorphous eosinophilic material was identified in the intestine, liver (serous), kidneys, lungs, and heart (epicardium) with findings of serositis, nephritis, and fibrinous epicarditis. The liver parenchyma and lungs had areas of congestion. There was both moderate and intense hepatocellular degeneration as well as degeneration in the renal tubular cells. These macro and microscopic changes were compatible with urate crystal deposition which represents visceral uric gout. Discussion: As opposed to free-living birds, birds in captivity have easy access to food and are sedentary. These factors, together with inadequate food management, make nutritional disorders the main predisposing cause of uric gout in these animals. Since it was not possible to determine the causative factors of this individual animal's disease due to the absence of examinations while alive, a nutritional origin of this animal's demise was considered. According to prior reports, an important cause of avian disease can be attributed directly or indirectly to kidney dysfunction. In addition to a deposition of amorphous material in the renal cortex, this Muscovy duck had areas of tubular cell degeneration and proliferation of fibrous connective tissue. However, it was not possible to establish a cause and effect relationship between the renal damage and the uric gout. Despite being common in birds under human care, the disease still is challenging for veterinarians, since the diagnosis is often late and treatment is often ineffective. The absence of documentation of this disease in the Muscovy duck contributes to the difficulty in establishing predisposing factors and a distinct disease etiology. This highlights the importance of the present report and the need for new studies. To the best of our knowledge, this is the first report of visceral uric gout in a Muscovy duck (Cairina moschata). This highlights the importance of necroscopic examinations and the impact they can have in the clinical arena, especially in wild animals.

RESUMO

RESUMO Objetivo identificar na literatura a formação do biofilme e o seu comportamento diante das intervenções em feridas cutâneas. Métodos revisão integrativa, realizada nas bases de dados Cumulative Index to Nursing and Allied Health Literature , Literatura Latino-Americana e do Caribe em Ciências da Saúde, EMBASE, Scopus, The Cochrane Library Collaboration , MEDLINE/PubMed e Science Direct, sem delimitação temporal. Foram selecionados 19 estudos. Avaliação das informações ocorreu de forma descritiva, confrontando com os achados pertinentes. Resultados os estudos da amostra foram publicados no idioma inglês e contemplaram três tipos de pesquisa de biofilme: dois clínicos, seis in vitro e 11 in vivo (animal). Incluíram-se três temas: criação de modelo biofilme (n=4), avaliação do biofilme (n=3), comportamento do biofilme diante de intervenções para o seu manejo (n=12). Conclusão efeitos prejudiciais do biofilme na cicatrização de feridas foram confirmados. Diversas intervenções foram capazes de reduzir e eliminar o biofilme nos modelos in vitro e in vivo . Contribuições para a prática constatou-se que avaliação clínica da lesão não permite identificar o biofilme, inclusive quando presente encontra-se abaixo da superfície da lesão. Este achado suscita reflexão por parte dos enfermeiros a respeito das intervenções adotadas para a remoção do biofilme.


ABSTRACT Objective to identify in the literature the biofilm formation and its behavior when faced with interventions in cutaneous wounds. Methods an integrative review, carried out in the Cumulative Index to Nursing and Allied Health Literature, Latin American and Caribbean Health Sciences Literature, EMBASE, Scopus, The Cochrane Library Collaboration, MEDLINE/PubMed and Science Direct databases, without temporal delimitation. Nineteen studies were selected. The information was evaluated descriptively, comparing it with the pertinent findings. Results the sample studies were published in English and included three types of biofilm research: two clinical, six in vitro and 11 in vivo (animal). Three themes were included: biofilm model creation (n=4), biofilm assessment (n=3), biofilm behavior before interventions for its management (n=12). Conclusion the detrimental effects of biofilm on wound healing have been confirmed. Several interventions were able to reduce and eliminate biofilm in in vitro and in vivo models. Contributions to practice it was found that clinical evaluation of the lesion does not allow the identification of biofilm, even when present; it is below the surface of the lesion. This finding raises reflection on the part of nurses regarding the interventions adopted for the removal of biofilm.

RESUMO

Background: Congenital anomalies are structural, functional, or metabolic defects caused by a combination of environmental, genetic, or even iatrogenic factors. Genetic defects, which can be inherited, are more common in purebred dogs. Teratogenic factors such as radiation, toxins, chemical agents, infectious diseases, mechanical influences, drugs given to the mother, and nutrition can affect the litter during gestational development. The incomplete division of a fertilized egg results in monozygotic, conjoined or Siamese twins, which are animals with complete or incomplete duplications. This paper reports on an adult bitch with monocephalus dipygus dibrachius and the surgical procedures. Case: A 2-year-old female Shih Tzu weighing 5 kg was admitted to a veterinary clinic, presenting with swelling and myiasis near the anus and several development disorders, characterized by 2 pelvises, 2 anuses, 2 vulvas, 2 forelimbs and 6 hindlimbs. Her physiological parameters were otherwise normal. Only the dog's myiasis was treated at this time due to the owner's financial straits. After 5 months, the owner brought the bitch back to the veterinary clinic because the animal presented with fecaloma in 1 of the anuses. Radiography revealed numerous alterations: seven lumbar vertebrae with marked vertebral axis deviation, reduced disc space, as well as ankylosis and fused ventral spondylosis at L6 and L7. Two pelvises fused medially by the wings of the ileum, with slight deviation and thinning of pelvic bones. Four hip joints and medial joints with pelvic avulsion and bone remnants of the pelvic limbs. Acetabular tearing slightly flattened femoral head and thickened femoral neck. Caudal vertebrae and vertebral axis located in left pelvis. Left lateral patella inserted in the trochlear groove and lateral dislocation of right patella. Right patellofemoral joint with smooth surface, preserved intra-articular density and cranial displacement of the tibia relative to the femoral condyles (cranial cruciate ligament rupture). An ultrasound analysis revealed 2 bladders. Two months later surgery was performed due to recurrent complications. During laparotomy 2 uteruses, 2 bladders and bifurcation of the intestine were observed. Ovariosalpingohysterectomy was performed in both uterus and enterectomy of the problematic intestinal portion. After 2 days of the surgery, blood transfusion was performed. After 2 days of the transfusion, there was extravasation of yellow fluid from the surgical cut and abdominal palpation was indicative of bladder rupture, so the patient was sent to emergency surgery. Unilateral nephrectomy and ureterectomy, and ruptured bladder cystectomy were performed. The dog remained hospitalized for 24 days after surgery, before it was released. Discussion: The classification of conjoined twins is based on the location of the junction and the number of limbs. Monocephalus dipygus dibrachius was diagnosed based on the fact that the dog had 1 skull, 2 thoracic limbs and 4 pelvic limbs, as well as the corresponding genitourinary and gastrointestinal tract alterations. Imaging scans are extremely important for a proper diagnosis to ensure appropriate surgery planning. The bitch was the result of inbreeding between a male dog and its offspring, which probably contributed to this malformation. There are very few reports of surviving adult conjoined animals, and even fewer descriptions of successful surgical treatments. To the best of knowledge of the authors, there are no previous reports of a surviving adult dog suffering from this malformation.

RESUMO

Human respiratory syncytial virus (HRSV) is the most frequent cause of severe respiratory disease in children. The main targets of HRSV infection are epithelial cells of the respiratory tract, and the great majority of the studies regarding HRSV infection are done in respiratory cells. Recently, the interest on respiratory virus infection of lymphoid cells has been growing, but details of the interaction of HRSV with lymphoid cells remain unknown. Therefore, this study was done to assess the relationship of HRSV with A3.01 cells, a human CD4+ T cell line. Using flow cytometry and fluorescent focus assay, we found that A3.01 cells are susceptible but virtually not permissive to HRSV infection. Dequenching experiments revealed that the fusion process of HRSV in A3.01 cells was nearly abolished in comparison to HEp-2 cells, an epithelial cell lineage. Quantification of viral RNA by RT-qPCR showed that the replication of HRSV in A3.01 cells was considerably reduced. Western blot and quantitative flow cytometry analyses demonstrated that the production of HRSV proteins in A3.01 was significantly lower than in HEp-2 cells. Additionally, using fluorescence in situ hybridization, we found that the inclusion body-associated granules (IBAGs) were almost absent in HRSV inclusion bodies in A3.01 cells. We also assessed the intracellular trafficking of HRSV proteins and found that HRSV proteins colocalized partially with the secretory pathway in A3.01 cells, but these HRSV proteins and viral filaments were present only scarcely at the plasma membrane. HRSV infection of A3.01 CD4+ T cells is virtually unproductive as compared to HEp-2 cells, as a result of defects at several steps of the viral cycle: Fusion, genome replication, formation of inclusion bodies, recruitment of cellular proteins, virus assembly, and budding.

RESUMO

Background: Pyometra or pyometritis is a serious and common condition of intact female dogs characterized by the inflammation of the uterus with a buildup of purulent exudate. It may be classified as open or closed. If untreated, pyometracan lead to uterine rupture and sepsis. Pyometra may also predispose to uterine torsion, defined as a rotation of one orboth uterine horns around its longitudinal axis. Uterine torsion in female dogs is rare, and usually with late pregnancy orparturition. This case report describes the clinical presentation and therapeutic management of uterine torsion correlatedwith open pyometra in a non-gravid bitch with no history of exogenous progesterone exposure.Case: A 10-year-old intact Yorkshire Terrier bitch weighing 3.2 kg was referred to a veterinary clinic in Porto Alegre,Brazil, with a 7 day history of prostration, anorexia, polydipsia, and sanguinopurulent vulvar discharge. Physical examination revealed pronounced abdominal tenderness. On abdominal ultrasonography, the uterus was enlarged and filled withcellular anechoic content, suggestive of pyometra. A complete blood count showed mild microcytic normochromic anemiaand leukocytosis. The animal was stabilized and an urgent ovariohysterectomy was performed. Preanesthetic analgesiaconsisted of subcutaneous methadone 0.3 mg/kg. Anesthesia was induced with propofol 3 mg/kg i.v. and maintained withinhaled isoflurane. During the procedure, significant enlargement of the left uterine horn and slight enlargement of theright uterine horn were observed. In addition, a torsion was identified near the left ovary, with copious sanguinopurulentsecretion. The animal remained under observation and fluid therapy for 48 h after the procedure and was discharged topostoperative follow-up. After discharge, the following treatment was medicine, local cleaning and rest for 14 days. Concluding...(AU)

RESUMO

Background: Burns are caused by a direct or indirect action of heat on an organism, compromising the functional integrityof the skin. Hypothermia is a common intercurrence in animals during the transoperative period; thermal mattresses areused to maintain the animals body temperature, but inappropriate use can cause the patients skin to burn. In humans, burnsare quite common; however, in veterinary medicine, they are infrequent. The aim of this study was to describe a case ofaccidental burn in a canine caused by a thermal mattress, emphasizing wound treatment and analgesia used.Case: A 12-year-old male canine without defined breed weighing 15 kg underwent an emergency exploratory laparotomydue to rupture of a spleen mass and presented with intercurrence hypothermia during the anesthesia procedure, which wascontrolled using a thermal mattress. Ten days after the surgical procedure, he developed a skin lesion with erythema, suffusion, and necrosis, evolving skin displacement along the entire back with a lot of pain which was possibly caused by theuse of a thermal mattress in the transoperative procedure. The intuited analgesic treatment involved the use of numerousand different drugs, including Methadone (0.3 mg/kg, QID, SC), Dipyrone (25 mg/kg, TID, IV), and Ketamine (0.5 mg/kg,TID, SC) (during hospitalization), as well as Tramadol (4 mg/kg, TID, PO) and Dipyrone (25 mg/kg, TID, PO) after medicalrelease as support therapy. For the wound treatment, calcium alginate was initially used daily and subsequently changedfor daily application of dermisana oil. The patient followed up weekly for approximately two months for wound monitoring as well as adjustments to the drug therapy. The would almost completely healed, but the patient showed a significantworsening in the general clinical condition correlated with the neoplasm that he had, and the owner and clinical staff ofthe veterinary hospital opted for euthanasia...(AU)

RESUMO

Background: The taxonomic order Anura is composed of frogs and toads, with approximately 6,000 species worldwide, of which 900 species are found in Brazil. Rhinella marina, popularly known as "sapo-cururu," is the most commonly found frog in Brazil. Although most of these animals are found in research laboratories and zoos, they are increasingly being reared as pets. Therefore, sedation or anesthesia is often necessary for these animals to facilitate medical care, complementary examinations, or surgical procedures. However, there are only a few reports of anesthesia in frogs. Therefore, the present report aimed to describe the anesthetic protocol for femoral osteosynthetic surgery in an adult cane toad. Case: An adult cane toad presented with a history of difficulty in moving the left hindlimb and loss of limb movements. Radiography showed a simple, complete, transverse, and closed average shaft of the left femur and bone shaft fracture deviation. The animal was referred for an osteosynthetic surgery to stabilize the fracture. Animal restraint was performed using humidified gloves on the operating table. As premedication, ketamine, meloxicam, and morphine were administered, and general anesthesia was induced with isoflurane through a face mask. The anesthesia was maintained with isoflurane through a drip on the animal's back for cutaneous absorption. Lidocaine (2%) anesthetic gel was applied on the incision line to complement the somatic analgesia. The fracture was fixed using an intramedullary Kirschner pin. The heart rate was measured based on the beep of the arterial pulse using a Doppler ultrasonic device, respiratory rate was recorded by visual observation of the animal's respiratory motion, and body temperature was assessed using an esophageal digital thermometer - all of these remained stable during the procedure. Morphine, enrofloxacin, and meloxicam were administered postoperatively. The animal was discharged from the hospital seven days after the surgery, and 14 days later, the animal was deemed clinically stable with favorable wound healing. Discussion: Toads use their skin to breathe and maintain osmotic balance. Therefore, their skin is extremely sensitive to dehydration, requiring constant wetting. General anesthesia in amphibians is recommended for prolonged and painful procedures, as in the present case. Different anesthetics, analgesics, and associated drugs may be used. Ketamine is often used for chemical restraint in amphibians, and the induction and recovery times may vary due to sensitivity and drug resistance. Inhalational anesthesia with isoflurane may also be effective; in the present case, the anesthetic was administered using a mask placed on the frog's skin, without any irritation. Analgesia is essential for any animal, and amphibians have opioid receptors that may be used as targets of non-steroidal anti-inflammatory agents. As indicated for all species, the animal was monitored throughout the procedure. Assessment of heartbeat is the simplest way to monitor anesthesia using Doppler (on the heart or throat); in the present case, was placed on the axillary artery for clear auscultation. In addition, other parameters, such as temperature and primary respiratory movements, were monitored. Anesthetic recovery can take hours or even days, whereas excretion depends on the metabolic rate of each animal. In the present case, recovery was observed 4 h after completion of the procedure, using fresh water on the animal's body to accelerate recovery, as indicated in the literature. This case demonstrated that anesthesia and medications used for anesthesia induction, maintenance, and recovery are safe in toads. For cane toads, during femoral osteosynthesis, this anesthetic procedure has never been described previously in the literature. Finally, such information can aid veterinarians in performing safe and adequate analgesic and anesthetic procedures for the wellbeing of animals.

RESUMO

Actinobacillosis outbreak with clinical manifestation of hippopotamus-like face observed in a property located in the municipality of Capão do Leão, Southern Brazil, in September 2016, is described. The cattle herd remained for most of the year in rice stubble. When these areas were occupied with new crops, they were transferred to areas where there were small native forests. Three cattle were affected. They presented a volume increase in the nasolabial and maxillary region, and there was also regional lymph node swelling. The evolution of the disease occurred in approximately six months. In tissue fragments collected for culture, Actinobacillus lignieresii was isolated. The diagnosis was based on clinical findings, histopathological evaluation characterized by the presence of piogranulomas with Splendore Hoepli reaction in its center, bacterial isolation, and identification of A. lignieresii by polymerase chain reaction (PRC) and genetic sequencing.(AU)

RESUMO

BACKGROUND: Cancer neoantigens have attracted great interest in immunotherapy due to their capacity to elicit antitumoral responses. These molecules arise from somatic mutations in cancer cells, resulting in alterations on the original protein. Neoantigens identification remains a challenging task due largely to a high rate of false-positives. RESULTS: We have developed an efficient and automated pipeline for the identification of potential neoantigens. neoANT-HILL integrates several immunogenomic analyses to improve neoantigen detection from Next Generation Sequence (NGS) data. The pipeline has been compiled in a pre-built Docker image such that minimal computational background is required for download and setup. NeoANT-HILL was applied in The Cancer Genome Atlas (TCGA) melanoma dataset and found several putative neoantigens including ones derived from the recurrent RAC1:P29S and SERPINB3:E250K mutations. neoANT-HILL was also used to identify potential neoantigens in RNA-Seq data with a high sensitivity and specificity. CONCLUSION: neoANT-HILL is a user-friendly tool with a graphical interface that performs neoantigens prediction efficiently. neoANT-HILL is able to process multiple samples, provides several binding predictors, enables quantification of tumor-infiltrating immune cells and considers RNA-Seq data for identifying potential neoantigens. The software is available through github at https://github.com/neoanthill/neoANT-HILL.

RESUMO

Background: Transmissible venereal tumor (TVT) is a common contagious neoplasm in dogs that spreads through coitus.Extra-genital presentations of this tumor are frequent and usually develop through implantation of neoplastic cells onexposed mucosae. TVT metastasis is rare, and when it happens its usually affecting regional lymph nodes and adjacentcutaneous tissue.Case: A female mixed breed dog, with estimated age of 7 to 11 months old, was rescued from the streets and taken to aveterinary clinic in the city of Porto Alegre, RS. The animal had multiple nodules on its body, vulva, ocular mucosa, andgingiva, along with signs of malnutrition and apathy. Cytological examination of the nodules and vulva was done andyielded a cytologic picture compatible with TVT. Weakly treatment with 0,3mg/m² vincristine sulphate was used untilclinical cure was noted. Approximately two weeks after clinical cure, the dog showed a blue colored eye and was referredfor ophthalmological, where it was diagnosed with vision loss due to glaucoma secondary to a neoplasm. The eye wasthen removed and sent for histopathological evaluation. Histopathology of the eye was compatible with TVT diagnosis.One month after enucleation the animal display dispenia, pain, aggressiveness and epistaxis. The animal was euthanizedand submitted for post-mortem evaluation. At necropsy there was a well-defined grayish-white, nodule near the thalamus.Similar nodules were also found on the lung, and anterior chamber of the eye. Histologically, all the nodules were compatible with TVT. Immunohistochemical examination was done, with the neoplastic cells being positive for vimentin andnegative for cytokeratin, CD79a, CD3 and CD117. Based on the post-mortem examination and clinical history, diagnosisof TVT...(AU)

RESUMO

O uso de um dispositivo auxiliar da marcha (DAM), como bengala ou andador, pode auxiliar os idosos na realização de suas atividades diárias, mantendo-os funcionalmente independentes e relativamente ativos. Porém, a utilização inadequada, o mau estado e as dimensões incorretas do dispositivo, assim como erros na prescrição do tipo de dispositivo podem aumentar o risco de quedas nos idosos usuários de DAM. Diante da falta de recomendações quanto à sua prescrição, o objetivo desse artigo é discorrer sobre os pré-requisitos para a prescrição de cada dispositivo (bengala e andador), de acordo com a nossa experiência adquirida na Área de Fisioterapia em Gerontologia, no Centro de Reabilitação (CER) do Hospital das Clínicas de Ribeirão Preto, considerando as evidências científicas disponíveis até o momento. Assim, com a difusão das informações contidas nesse artigo para os profissionais da saúde que prestam assistência a idosos, espera-se aprimorar a prática de prescrição do DAM e de educação do idoso, de seus familiares e cuidadores, a fim de que sejam alcançados os benefícios do uso de um DAM e prevenidos os possíveis eventos adversos, como as quedas.


The use of a walking aid device (WAD), such as a cane or walker, can assist older adults in performing their daily activities, keeping them functionally independent and relatively active. However, improper use, poor condition and incorrect dimensions of the device, as well as errors in prescribing the type of device may increase the risk of falls in older people who use a WAD. Given the lack of recommendations on its prescription, the purpose of this article is to discuss the requirements for the prescription of each device (cane and walker), according to our experience obtained in the area of ​​Gerontology Physiotherapy in the Rehabilitation Center (CER) of the Hospital das Clínicas de Ribeirão Preto, considering the scientific evidence available at the moment. Thus, by disseminating the information contained in this article to health professionals who provide care to older people, it is expected to improve the practice of prescribing WAD and educating the older adults, their families and caregivers, in order to achieve the benefits of use a WAD and prevent possible adverse events such as falls.

RESUMO

Lymphoma is a neoplasm that originates from solid hematopoietic tissues and is one of the most common tumors in dogs. The goal of the present study was to perform a retrospective study of canine lymphomas diagnosed at the "Laboratório Regional de Diagnóstico", at the "Faculdade de Veterinária" of the "Universidade Federal de Pelotas" (LRD-UFPel) from 2000 to 2017, to determine the epidemiology and anatomical distribution, and to evaluate the histopathological and immunohistochemical aspects of each case according to the adapted Kiel classification. The protocols for necropsies and biopsies in the laboratory were reviewed. Lymphoma was diagnosed in 77 dogs. Approximately 37.7% (29/77) of affected dogs had no defined breed, while dogs with defined breeds accounted for 58.4% (45/77) of the diagnoses. The occurrence in males (40/77) was slightly higher than that in females (36/77), and the mean age was 8.1 years (1.4-17 years). The most affected age group was between six and 10 years of age with 31 cases (40.2%). Regarding the anatomical classification, the multicentric form was the most prevalent, accounting for 71.4% (55/77) of the diagnoses. In 40 cases that immunophenotyping was performed, B-cell lymphomas represented 62.5% of the diagnoses (25/40), while T-cell lymphomas corresponded to 37.5% of the diagnoses (15/40). The degree of malignancy according to the modified Kiel classification was low in 35% of lymphomas (14/40) and high in 65% of cases (26/40). The multicentric form was more frequent in the region of influence of the LRD-UFPel. Identification of the immunophenotype can improve the quality of life and survival in affected dogs since it allows the most appropriate treatment for each patient.(AU)

Foram revisados os protocolos de necropsias e biópsias recebidos no laboratório identificando-se 77 casos de cães com diagnóstico de linfoma. A doença afetou cães sem raça definida em 37,7% (29/77) dos casos, enquanto os cães com raças definidas tiveram 58,4% (45/77) dos diagnósticos. A ocorrência em machos (40/77) foi discretamente maior do que em fêmeas (36/77) e a idade média foi de 8,1 anos (1,4-17 anos). A faixa etária mais acometida foi entre seis e 10 anos de idade com 31 casos (40,2%). Quanto à classificação anatômica a forma multicêntrica foi a mais prevalente atingindo 71,4% (55/77) dos diagnósticos. Em 40 casos em que a imunofenotipagem foi realizada, os linfomas de células B representaram 62,5% dos casos (25/40), enquanto os linfomas de células T equivaleram a 37,5% dos diagnósticos (15/40). O grau de malignidade de acordo com a classificação de Kiel modificada foi baixo em 35% dos linfomas (14/40) e alto em 65% dos casos (26/40). Conclui-se que a forma multicêntrica é mais frequente na região de influência do LRD-UFPel e que a identificação do imunofenótipo pode melhorar a qualidade de vida e dar maior sobrevida aos cães afetados uma vez que permite o tratamento mais adequado para cada caso.(AU)

RESUMO

Rabies affects several domestic species, causing significant economic losses due to the death of animals in characteristic areas of the southern region of Rio Grande do Sul. In this context, this work aimed to study the epidemiology of rabies outbreaks observed in cattle from January 2008 to December 2017, through its space and time distribution in the southern region of Rio Grande do Sul. We performed an observational and ecological retrospective through the analysis of data recorded in necropsy protocols performed in cattle at the "Laboratório Regional de Diagnóstico" of the "Universidade Federal de Pelotas" (LRD-UFPel). A descriptive data analysis aimed at evaluating the distribution of cases over time. The statistical analysis was performed with Gretl statistical software 1.9.12 (GNU Regression, Econometric, and Time-series Library). To the existence of stationarity was verified with the Dickey-Fuller test, considering a value of p<0.05. From January 2008 to December 2017, 1418 bovine diagnostic materials were received at the LRD-UFPel, and 160 outbreaks of rabies were confirmed in 160 farms located in the 24 municipalities of the LRD-UFPel area of influence. We observed 591 cattle out of a total of 25,886 infected with the virus. We conclude that rabies does not exhibit seasonality in the study region, with a tendency to decrease in frequency in the next years. The disease has an epidemic characteristic in most of the analyzed months (2012-2014), remaining endemic in the remaining period (2011, 2015 and 2016) with sporadic episodes of epidemics in these years. We also observed that as the incidence of the disease increased in the animals and in the properties, there was a geographical spread of the virus for the majority (54.16%) of the municipalities in the area of influence of the LRD-UFPel.(AU)

Para a análise temporal foi utilizado o software estatístico Gretl 1.9.12 (GNU Regression, Econometricand Time-series Library). Para verificar a existência da estacionariedade utilizou-se o teste de Dickey-Fuller aumentado, considerando um valor de p<0,05. No período de janeiro de 2008 a dezembro de 2017, foram recebidos no LRD-UFPel 1418 materiais de bovinos para diagnóstico, sendo confirmados 160 surtos de raiva em 160 propriedades situadas nos 24 municípios da área de influência do LRD-UFPel. O número de animais infectados pelo vírus foi de 591 bovinos de um total de 25.886. O presente estudo permitiu concluir que a raiva não tem sazonalidade na região do estudo, tendo tendência de queda na frequência nos próximos anos. A doença tem característica epidêmica na maioria dos meses analisados (2012-2014), mantendo-se endêmica no período restante (2011, 2015 e 2016) com episódios esporádicos de epidemias nestes anos. Observou-se ainda, que na medida em que aumentou a incidência da doença nos animais e nas propriedades, houve disseminação geográfica do vírus para a maioria (54,16%) dos municípios da área de influência do LRD-UFPel.(AU)
