Características fenotípicas do nanismo em pôneis neonatos: relato de casos

Three newborn Mini-Horses and one Brazilian Pony horses were presented to the Veterinary Hospital with phenotypic appearance of dwarfism. They had relatively larger head conformation, occlusive dental defect and musculoskeletal changes such as abnormal short limbs and deformation on the third metatarsal bone. The radiographic examination showed abnormal growth plates on femoral condyle and proximal thirds metatarsal bones. Due to the high possibility of future complications and quality of life loss, the animals were euthanized. We emphasize the importance of recognition of phenotypic changes related to dwarfism in horses, enabling the phenotypic diagnosis can direct crossings for nontransmission of this abnormality as genetic inheritance.

Undifferentiated pulmonary adenocarcinoma of clear cells associated to hypertrophic osteopathy in a dog

Background: Most of the primary pulmonary tumors in dogs are malignant and from epithelial origin, being bronchioalveolar tumors more prevalent. Adenocarcinoma of clear cells, however, is a very rare pulmonary tumor and its origin is still unknown. It is related to several clinical abnormalities, including hypertrophic osteopathy, an unusual paraneoplastic syndrome characterized by a periosteal reaction along the shaft of long bones. Because of the unusual presentation of the pulmonary adenocarcinoma, the aim of this study was to describe the radiographic, histopathological, and immunohistochemical fi ndings of a dog affl icted with hypertrophic osteopathy secondary to an undifferentiated pulmonary adenocarcinoma of clear cells. Case: A 12-year-old, 45 kg, not castrated male Great Dane dog was presented with painful swelling of all four limbs and moderate respiratory distress. Radiographic examination and computed tomography of the limbs showed palisade-like periosteal bone proliferation involving radius, ulna, femur, patella, tibia, fi bula, tarsus, metacarpal, metatarsal and digits, suggesting hypertrophic osteopathy. Radiographic examination and computed tomography of the lungs also showed a round mass well delimited localized in the right diaphragmatic lobe. A lobectomy of the right diaphragmatic lobe and partial lobectomy of accessory lobe were performed. A poorly differentiated clear squamous cell carcinoma was diagnosed by histological examination. An immune-panel of CK5/CK6, CK7, p63 and TTF-1 was used for immunophenotyping. Immunostaining was weakly positive for CK5/CK6 and negative to all others. Therefore, the diagnosis was poorly differentiated clear cell adenocarcinoma. The dog showed improvement in clinical signs seven days after surgery. One month postoperatively, radiographic examination of the limbs showed less intense periosteal reaction and initiation of bone remodeling. Discussion: Primary pulmonary tumors are considered very infrequent in small animals, but its true incidence rate is dif- fi cult to establish in animal populations. The histological origin of the tumor in the present case, as verifi ed in the literature, is not well established by histological analysis. In these situations, the immunohistochemistry panel may be useful. The modifi cation of the diagnosis between histological analysis and by immunohistochemistry, among other factors, might be due to transdifferentiation from one phenotype to another at various stages in the neoplastic process. The clear cell appearance observed in this case may be verifi ed in all types of carcinoma due to intracellular accumulation of glycogen, most of which is dissolved during the preparation of paraffi n sections. This uncommon neoplasm apparently did not infl uence the radiographic or tomographic fi ndings of the hypertrophic osteopathy in the present case. The frequency of metastases depends on the histological type of the tumor, being common in the pulmonary adenocarcinoma and usually to tracheobronchial lymph nodes and pulmonary parenchyma. Although in this case the imaging studies did not show metastases to other pulmonary lobes, the histological exams showed metastatic lesions that may be associated to the dog’s death after the surgery.

Doença cerebelar em cães e gatos

Diseases of the cerebellar system are common in small animals, and result in a clinical syndrome characterized by hypermetria, base-wide stance and intentional tremors of the head and body. All movements of the limbs are spastic and awkward. The neurological examination assists in the localization of lesions restricted to the cerebellum or in the detection of disorders relating to other parts of the nervous system, which characterizes a multifocal disease process. Neurological disorders in dogs and cats may suggest a very extensive list of differential diagnoses, since they may be caused by infectious, degenerative and traumatic processes, among others. The possible etiologies for cerebellar syndrome include: aplasia and hypoplasia, abiotrophy, cancer, vascular stroke and inflammatory disorders. The aim of this paper is to review the clinical signs that aid in the location of the cerebellar lesion and discuss the possible causes of this syndrome in dogs and cats.

Manifestação incomum de paralisia de membros pélvicos em felino com hidronefrose decorrente de ovariectomia - Relato de caso

This study describes the occurrence of iatrogenic hydronephrosis in left kidney with compression of the abdominal aorta in persian cat and paralysis of hind limbs. The animal had slight dehydration, pale mucous membranes, cold extremities and cyanotic, absence of bilateral femoral artery pulse, and absence of superficial and deep pain, and presence of a mass of firm consistency with six centimeters in diameter, on abdominal palpation. Performed exploratory celiotomy, there was increased left kidney compressing the abdominal aorta and dilation of the cranial left ureter attached to the uterine horn by means of ligation with nonabsorbable. After nephrectomy, it was observed the restoration of local circulation. The animal died after eight hours.
