RESUMO

Background: Reports of yeast isolates resistant to traditional antifungal drugs have become common. Similarly, refractory clinical cases treated with these traditional antifungal drugs have also been reported. These cases ‘may or may not be related to pregnancy. Newly developed therapeutic approaches, such as the immunostimulant β-glucan combined with the traditional antifungal agents show promising results. Therefore, knowledge of the effects of these new associations is essential. The aims of this study were to evaluate the effects of the combination of itraconazole and β (1-3) glucan on fertility in female rats and its interference in the development of their offspring, including teratogenic potential.Materials, Methods & Results: A total of 180 female Wistar rats (90 days old) separated into six groups were used (n = 30 per group): Negative Control - treated daily with the volume corresponding to 10 mL.kg-1 of sterile distilled water orally, and 0.25 mL of sterile 0.9% NaCl solution subcutaneously weekly; IT - treated daily with itraconazole at a dose of 10 mg.kg-1 orally, and 0.25 ml of sterile 0.9% NaCl solution subcutaneously weekly; Beta - treated daily with the volume corresponding to 10 mL.kg-1 of sterile distilled water orally, and 0.5 mg of β (1-3) glucan subcutaneously weekly; DT - treated daily with itraconazole at a dose of 10 mg.kg-1 orally, and 0.5 mg of β (1-3) glucan subcutaneously weekly; DT5x - treated daily with itraconazole at a dose of 50 mg.kg-1 orally, and 0.5 mg of β (1-3) glucan subcutaneously weekly; DT10x - treated daily with itraconazole at a dose of 100 mg.kg-1 orally, and 0.5 mg of β (1-3) glucan subcutaneously weekly. The rats were treated before (14 days) and during the mating period (up to 21 days), pregnancy (21 days) and lactation (21 days).[...]

RESUMO

Durante a avaliação radiográfica aos 60 dias de pós-operatório de estabilização vertebral em um cão, foi observada a presença de um pino de Steinmann intra-abdominal. Foi realizada cirurgia laparoscópica para inspeção cavitária e remoção do objeto. O implante estava envolvido pelo omento, não sendo observados sinais de infecção. O procedimento foi executado em 15 minutos e permitiu mínimo trauma. Os autores não encontraram relatos da migração desse tipo de implante para a cavidade peritoneal em cães com sucessiva remoção videocirúrgica.


An intra-abdominal Steinmann pin was detected during a radiographic assessment of the 60th post- operative day of a vertebral stabilization in a dog. Laparoscopic inspection and retrieval of the foreign body were performed. The implant was surrounded by omentum with no noticeable signs of infection. The procedure was performed within 15 minutes with minimal trauma. To the authors' knowledge, this is the first report of this kind of implant migration to the peritoneal cavity followed by laparoscopic removal in dogs.

RESUMO

Background: Panniculitis can be associated with a group of multifactorial diseases that develop intense inflammatory response of the subcutaneous fat tissue. The damaged fat cells suffer hydrolysis and saponification. The etiology remains unknown, although it has been associated with infectious agents, vascular pathologies, pancreatic disorders, neoplasms, immunologic diseases and nutritional deficiencies. Nodular sterile panniculitis is referred to the fat subcutaneous tissue inflammation without the presence of microorganisms and generally is presented with multiple or single nodules associated either with systemic or traumatic issues. This assay reports a case of traumatic Panniculitis presented as a single nodule on a dog admitted at the Veterinary Teaching Hospital of Passo Fundo University (HV-UPF), State of Rio Grande do Sul, Brazil, emphasizing the clinical signs, diagnosis and surgical treatment. Case: An adult mixed breed bitch, weighting 7,5 kg, was admitted at the HV-UPF because of a one-month evolution of a dorsal thoracic subcutaneous mass. Symptomatic treatment with unknown oral antibiotics was administered by another veterinarian, who also tried to perform local puncture drainage unsuccessfully. There was no previous history of local puncture or subcutaneous drug infiltration that could explain the mass. During physical examination, a single, painless and nodular subcutaneous mass (4 x 6 cm) was located on the dorsal thoracic median line, below the scapula, discharging a serosanguineous fluid probably due to the previous puncture. No other occurrences were found. The patient was treated with cephalexin and meloxicam. Hematological and biochemistry examinations were within reference range. Cytological exam demonstrated slightly degenerated neutrophilis and a great amount of adipose tissue. This could suggest, among other pathologies, neoplasm. Surgery was performed after 15 days. An elliptical incision was performed maintaining a 2,5 cm safety margin from the mass. Histopathological findings were compatible with sterile nodular panniculitis, likely traumatic. Discussion: There was a single, firm, regular, painless nodule, correspondent with other studies. The lesion location was also similar to other author's findings. Cytological findings were unspecific and could lead to several diagnoses. Careful pathologic study is necessary to differentiate from benign or malignant neoplasms and other affections. The hematological and biochemistry examinations, ultrasounds and radiographs were all within reference range on the case. These diagnose tools are very important and should always be used in order to achieve the correct screening, diagnosis and treatment. Surgical removal was considered effective, once 7 months after the treatment there was no local recurrence, with great cosmetic result.

RESUMO

Entre os problemas cirúrgicos das aves, as fraturas são os de maior prevalência. Em virtude das variações no tamanho, peso, anatomia óssea peculiar, alta incidência de fraturas complicadas e das diferentes demandas funcionais entre espécies e indivíduos, não foi possível estabelecer ainda um método ideal de osteossíntese para os ossos longos das aves. Microplacas de titânio comumente utilizadas em cirurgias maxilofaciais de humanos foram empregadas recentemente na osteossíntese de aves, porém com poucos resultados disponíveis. O objetivo do presente estudo foi avaliar a utilização das microplacas de titânio no tratamento de fraturas experimentais de tibiotarso em pombos domésticos (Columba livia). Foram utilizadas 30 aves adultas, machos e fêmeas, com 7 meses de idade, pesando entre 400 a 500 gramas. Os animais foram separados em três grupos de dez, sendo que no grupo 1 foi utilizado uma microplaca de titânio com 6 furos e espaçador central; no grupo 2, com oito furos sem espaçador central; e, no grupo 3, com oito furos com espaçador central. Após avaliação clínica, as aves foram submetidas à osteotomia médio-diafisária no tibiotarso direito para colocação das diferentes configurações de microplaca de titânio, sendo fixadas com microparafusos de titânio com 7mm de comprimento. Os animais foram avaliados clínica e radiograficamente até os 90 dias de pós-operatório. Após esse período, foi realizada eutanásia em duas aves de cada grupo. Em todas elas, foi observada a consolidação óssea, sendo que, no grupo 1, o tempo médio e o desvio padrão foram 32,9±9,9; no grupo 2, 30,8±6,7 e, no grupo 3, 26,6±6,4 dias, não havendo diferença estatística entre os grupos. O envergamento do implante foi a complicação mais frequente. A configuração da microplaca resultou em diferença estatisticamente significativa em relação à deambulação e ao grau de envergamento nos diferentes grupos, sendo que, no grupo 3, houve maior precocidade no apoio do membro e menor grau de envergamento em relação aos outros grupos. Histologicamente, foi verificada a formação de calo ósseo em todos os animais e presença de tecido ósseo ao redor da microplaca e dos microparafusos. Apesar das complicações observadas, as microplacas de titânio são uma opção para osteossíntese de tibiotarso em aves de médio porte.


Among the surgical problems in birds, the fractures are the most prevalent. Due to variations in size, weight, peculiar bone anatomy, high incidence of complicated fractures and functional demands of different species and individuals, it is still not possible to establish an ideal method for osteosynthesis of long bones in birds. Titanium microplates commonly used in human maxillofacial surgery have been recently employed in osteosynthesis of birds, but with few results available. The aim of this study was to evaluate the use of titanium microplates in the treatment of tibiotarsus fractures in 30 pigeons (Columba livia) , adult males and females, with 7 months old, weighing from 400 to 500. The animals were divided into 3 groups with ten animals each. In group 1, a titanium microplate with 6 holes and a central spacer was used; in group 2, a titanium microplate with 8 holes without a spacer in the center was used; in group 3, a titanium microplate with 8 holes with central spacer was used. After clinical evaluation, the birds were submitted to mid-diaphyseal osteotomy in the right bone for placement of different configurations of the titanium plate, and fixed with titanium microscrews 7mm long. The animals were evaluated clinically and radiographically until 90 days postoperatively. After this period, euthanasia was performed in 2 animals from each group. In all animals was observed bone healing and in group 1 the mean and standard deviation were 32.9±9.9 days, in group 2, 30.8±6.7 days in group 3, 26.6±6.4 days. There was no statistical difference in healing time between groups. The bending of the implant was the most common complication. The configuration of the plate resulted in a statistically significant difference in relation to walking and to the degree of bending in the different groups. Moreover, in group 3 there was higher precocity in the member suppor and a lower degree of bending in relation to other groups. Histologically, it was verified formation of the callus in all animals and presence of bone tissue around the plate and microscrews. Despite the complications of titanium microplates, they are an option for tibiotarsus osteosynthesis in birds of medium size.

RESUMO

Luxating patella is one of the most frequent conditions of the stifle joint in dogs and it can evolve into a degenerative joint disease. The occurrence of the condition can be medial or lateral, unilateral or bilateral. Its origin can be traumatic or congenital and, additionally, it may undergo genetic and environmental influence. Lateral luxation is more common in large breed dogs, and it can rarely affect medium and small breeds, whilst medial luxation is more common in small breed dogs. The classification of patellar luxation comprises four grades, according to the patellar position, clinical signs and seriousness of the bone deformities found. The diagnosis is made based on the clinical evaluation, associated with a radiographic evaluation. The present study aims at describing a case of bilateral grade 3 lateral luxating patella in a Toy Poodle dog.(AU)
