Forty-four stifle joints of 32 client-owned dogs were included in this study. Dogs were presented for hindlimb lameness and suspected cranial cruciate ligament rupture. The diagnostic procedures included radiographic examination. The mediolateral projection of the stifle joint including the tibia and the tarsal joint was used in this study. We tested the most widely used gold standard method as well as three additional methods for tibial plateau angle measurement on each joint. The tibial plateau angle, the positioning of the stifle joint and the presence of osteoarthrosis were recorded. Only 29 (66%) joints had correct position on the radiograph and were used for further study. Repeated-measures ANOVA identified significant differences in mean tibial plateau angle between the different measuring methods. Dunnett's post-hoc test identified a significant difference between the TA-2 and TA-2i methods and TA-0. No significant differences in tibial plateau angle were identified between joints with and without osteoarthrosis. The positioning of the limb significantly influenced the tibial plateau angle. One of the modified methods was found to not differ significantly from the gold standard method; thus, it can be recommended for further testing.

The aim of this study was to describe the influence of internal or external rotation of the femur on the projected radiographic position of the patella within the trochlear groove, and on the femoral head in relationship to the acetabulum in the standard ventrodorsal hip extended view, i.e., medial or lateral patella displacement, Norberg angle, femoral head subluxation index and femoral head subluxation category. Eleven adult dog cadavers of large and giant breeds were radiographed in standard ventrodorsal hip extended view and with internal and external femoral rotation. The medial and lateral patella displacement, Norberg angle, subluxation index and subluxation category variables were measured on radiographs, and analysed comparing the normal position with positions of different degrees of internal or external rotation of the femur. In the normal ventrodorsal hip extended view, the patella was centred within the distal femoral metaphysis (P > 0.05). A mean ± SD internal femoral rotation of 16.0 ± 5.9° resulted in a medial patella index displacement of 0.23 ± 0.09, and a mean external femoral rotation of 17.9 ± 6.7° resulted in a lateral patella index displacement of 0.24 ± 0.1. The mean Norberg angle was 105.3 ± 4.3°, 107.7 ± 5.5° and 104.2 ± 4.3° (P < 0.05); the subluxation index was 0.15 ± 0.06, 0.12 ± 0.05 and 0.18 ± 0.06 (P < 0.05); the subluxation category was 1.55 ± 0.6, 1.46 ± 0.7 (P > 0.05) and 1.96 ± 0.65 (P < 0.05) in normal, internal and external femoral rotation ventrodorsal hip extended views, respectively. In conclusion, as the Norberg angle, subluxation index and subluxation category are parameters used for classification in the main international hip dysplasia scoring systems, adequate femoral position with the patella centred in the distal metaphysis is of uppermost importance to ensure the technical quality of radiographs.

During the summer, only a few pesticides such as desiccants, typically quaternary ammonium (quat) and glyphosate formulations, are applied. We therefore analysed samples of not only a wide range of pesticides, but also desiccants. Additionally, we analysed dying honeybees, already dead individuals and comb pollen from the case hive. The LC-MS/MS (triple quadrupole) analysis of glyphosate-based quaternary ammonium pesticides (quats) and a wide range of 148 other pesticides allowed identification of 23 different pesticides in the samples: (I) two quats, (II) twelve fungicides, (III) four insecticides, (IV) four herbicides and (V) one rodenticide. The plant growth regulator chlormequat was the pesticide identified in the highest amounts and was present in all of the analysed samples (bees and pollen). However, it is regarded as being practically non-toxic to honeybees. In summary, this manuscript describes the detection of quat in honeybees and pollen.

Cerebellar and thyroid masses were identified using 0.3T magnetic resonance imaging. The 18F-fluorodeoxyglucose uptakes of the masses were elevated on positron emission tomography and 7 T-magnetic resonance imaging fusion imaging. At 113 days after the initial presentation, new nodular lesions were observed in the skin, liver and spleen. Histopathology revealed multiple lesions of disseminated histiocytic sarcoma in the cerebellum, liver, spleen and skin, whereas the thyroid lesions were diagnosed as mixed medullary-follicular thyroid carcinoma. The primary site of the disseminated histiocytic sarcoma was found to be in the cerebellum. To our knowledge, this is the first case report to describe the imaging and histopathological findings of extracranial metastasis of a primary intracranial histiocytic sarcoma in a dog.

On clinical examination, the dog showed deformity of the left nasal plane in the absence of any cutaneous lesions or nasal discharge, and presented with nasal snoring noises during both the inspiratory and expiratory phases. The patency of nasal cavities was evaluated using the cotton swab test, and was found to be preserved only on the right side. Endoscopic, radiographic and computed tomographic examination revealed an osteoproductive lesion that distorted the nasal, maxillar and frontal bones, completely occupying the left nasal cavity and frontal sinuses, resulting in destruction of the nasal septum and invasion of the contralateral nasal cavity. Five bioptic samples of the mass were collected from the cutaneous surface using a 9G Jamshidi bone marrow bioptic instrument. Histologically, the lesion consisted of a non-encapsulated, multilobulated mass composed of dense coalescing trabeculae of well-differentiated bone, which was lined by osteogenic cells. The morphology was suggestive of nasal osteoma. Due to the large size of the mass, evidenced by computed tomography, chronic systemic nonsteroidal anti-inflammatory treatment with carprofen was proposed instead of surgery. The description of this case is useful for veterinarians, who should consider osteoma as a possible differential diagnosis for nasal tumours.

The use of low-field MRI for 3D volume rendering has been described in human medicine, but no such reports are available as yet in veterinary medicine. A two-year-old male mongrel dog (8.5 kg body mass) with an unknown previous history of hindlimb lameness was presented to our clinic. The left stifle joint was hyperextended, slightly enlarged and it showed a limited range of motion. Three-dimensional sequences were used to visualise bones of the stifle joint. Optimal values of in-plane spatial resolution were obtained for small structures. The developed 3D model contributed to our understanding of the spatial localisation of bone deformities in the patient, which was crucial in surgical planning. This report shows that three-dimensional models do significantly enhance the clinical applicability of low-field MRI.

Clinical examination revealed a non-weightbearing left limb, pain upon manipulation of the hip joint, complete immobilisation of the stifle joint and muscle atrophy in the left thigh. Low-field magnetic resonance images were acquired in sagittal, transverse and dorsal planes with T1-weighted spin echo, T2-weighted fast spin echo, T1-weighted gradient echo, gradient echo short tau inversion recovery and T1-weighted XBone sequences. Total examination time was 59 min 20 s. The obtained images revealed the presence of osteophytes on the surface of the femoral head, subluxation of the hip joint, atrophy and fatty infiltration of the quadriceps femoris muscle. The symmetry and size of callus in the fracture site were also evaluated. Based on the results of the magnetic resonance imaging exam, the patient was diagnosed with hip osteoarthritis, atrophy and fatty degeneration of the quadriceps femoris muscle with homogeneous and symmetrical distribution of callus in the fracture site. The results of this study confirm the high diagnostic value of low-field magnetic resonance imaging in diagnostics of musculoskeletal injuries in cats.

For this purpose, clinical observation, ELISA fowl adenovirus and chicken anaemia virus antibody detection in serum at 21 and 42 days, mortality evaluation, epidemiological analysis, histology and genetic identification were performed. The six flocks of the farm consisted of 90,000 chickens. Only one flock of 15,000 chickens was affected on this farm. At 19 days of age, ill chickens showed clinical signs of depression, anorexia, somnolence, ruffled feathers, anaemic comb and wattles and occasionally nervous signs. Based on ELISA titres, the antibody response to fowl adenovirus increased greatly from 21 to 42 days. The antibody response to vaccination against infectious bursal disease virus and chicken anaemia virus was at the expected level in all broiler flocks. Necropsy showed diffuse petechial and ecchymotic haemorrhages in skeletal muscles, liver, pancreas, kidney, together with hepatomegaly, splenomegaly and catarrhal enteritis. Histologically, fatty liver degeneration, multifocal liver necrosis and intranuclear inclusions in hepatocytes, as well as focal necrosis in pancreas and spleen parenchyma were seen. The DNA of AAV-1 (avian adenovirus group 1) was detected using the PCR method in paraffin-embedded liver samples. The results revealed no association of inclusion body hepatitis with infectious bursal disease virus or chicken anaemia virus infection, and suggested primary disease. However, the involvement of only one chicken flock on the farm remains unexplained.
