Perfuração esofágica associada a corpo estranho em cão / Esophageal perforation associated with a foreign body in a dog

Background: The esophagus is a tubular organ that connects the laryngopharynx to the stomach. This organ has three pointsof narrowing: the thoracic inlet, the base of the heart, and the diaphragmatic hiatus; these are common sites of obstructionby foreign bodies. Clinical signs of esophageal obstructions include sialorrhea, dysphagia, regurgitation, dehydration, anddepression. The diagnosis is based on clinical examination, anamnesis, and complementary imaging. The treatment requiresthe removal of the foreign body. Herein, we report a case of esophageal perforation associated with a foreign body in aSpitz German treated at the Veterinary Hospital of the Federal Rural University of Pernambuco.Case: A 2-year-old female German Spitz was referred to the Veterinary Hospital of the Federal Rural University of Pernambuco (HV-UFRPE); she presented with recurrent drooling and emesis. According to the instructor, approximatelyfive days after a party at the residence, the animal began to exhibit clinical signs. She was examined at a veterinary clinic,where she remained hospitalized for three days, without clinical improvement. She was then taken to the HV-UFRPE forfurther assessment. Upon physical examination, sialorrhea, hypercormed conjunctival mucosa, hyperthermia (41ºC), andregurgitation were observed. Imaging tests (simple radiography and ultrasonography), blood count, and a serum biochemistry panel (urea, creatinine, alanine aminotransferase, alkaline phosphatase, total protein, and albumin) were requested.The radiographic examination revealed a pulmonary interstitial pattern and pleural effusion. Analysis of the thoracic fluidyielded results consistent with a septic exudate. No significant changes were observed on total abdominal ultrasonography.The hemogram showed thrombocytosis, leukocytosis with absolute neutrophilia, as well as relative and absolute monocytosis. Esophagoscopy was offered...(AU)

Ocorrência simultânea de hemangiossarcoma e mastocitoma de grau II em cão da raça Pitbull / Simultaneous occurrence of hemangiosarcoma and grade II mast cell tumor in a Pit Bull Terrier

Background: The incidence of cutaneous neoplasms in dogs is high and quite variable. Hemangiosarcoma (HSA) and mast celltumor (MCT) are commonly diagnosed neoplasms in isolation; however, reports of concomitant occurrence in a single patientare rare. HSA is a malignant mesenchymal neoplasm of endothelial origin; the spleen is the most commonly affected organ.MCT is a common neoplasm that may affect any region of the body, without predilection for sex, although some breeds haveshown higher incidence. This report describes a case of HSA and MCT in a Pit bull terrier.Case: A 5-year-old white male Pit bull was presented to the Small Animal Clinic of the Federal Rural University of Pernambucowith nodules in preputial region measuring 5.4 x 3.7 cm and an ulcerated nodule in the right lateral thoracic region measuring23.0 x 19.0 x 5.5 cm. The owner reported surgical excision of two previous nodules one year before the consultation, but neitherwere submitted for cytopathological or post-surgical histopathological examination. Two months after the procedure, the nodulesrecurred. Cytopathological examinations of preputial and lateral thoracic nodules were performed, with a suggestive diagnosisfor HSA and MCT, respectively. Due to the unfavorable prognosis and the weakness of the animal, euthanasia was elected.Necroscopic examination revealed an ideal body condition score (4/9), hypertrophy of right pre-scapular and axillary lymphnodes, red hepatization in the apical lobe of the right lung, with multiple, soft and pigmented nodules in the spleen, liver, pancreas and testis. Several tissue samples were collected, conditioned in 10% buffered formaldehyde solution, routinely processedfor histology, and stained with hematoxylin-eosin and toluidine blue. Microscopically, the lateral thoracic nodule consisted ofround cells in cordonal arrangement, with sparse basophilic and discretely granular cytoplasm...(AU)

Isolation and identification of Mycobacterium bovis in cattle slaughtered from an abattoir in Garanhuns, Pernambuco / Isolamento e identificação de Mycobacterium bovis em bovinos abatidos em matadouro público de Garanhuns, Pernambunco

Tuberculosis is a chronic infectious disease caused by the Mycobacterium tuberculosis complex (CMT), members including M. bovis. The sanitary inspection in slaughterhouses has a great importance on public health for the removal of contaminated meat with pathological lesions. Cattle slaughtered in the abattoir of Garanhuns were subjected to macroscopic, histological, bacteriological, and molecular analyses. Lung inspection revealed gross lesions suggestive of tuberculosis. The characterization of tuberculous granulomas was performed by histopathology and hematoxylin and eosin (HE) staining. The identification of acid-fast bacilli (AFB) was performed on smears with fresh material and histological staining using Ziehl-Neelsen stain. Bacteriological diagnosis was carried out using Stonebrink and Lowenstein-Jensen media, and polymerase chain reaction (PCR) was performed from the DNA extracted from colonies for the identification of Mycobacterium spp. We found that 1% (32/3,.180) of the collected lungs showed lesions suggestive of tuberculosis. Histopathological analysis revealed that 65.62% (21/32) samples had granulomatous pneumonia. AFB was detected in 46.88% (15/32) smears and 4.16% (1/24) histological sections, as analyzed by Ziehl-Neelsen staining. Moreover, 68.75% (22/32) samples showed bacterial growth and molecular identification 90% (18/20) of the samples were positive...(AU)
