RESUMO

O tricolemoma é uma neoplasia benigna, rara em cães, que se originam da bainha externa da raiz do folículo piloso. O presente trabalho relata um caso de tricolemoma em cadela da raça Serra da Estrela, fêmea de 9 anos que veio para atendimento no Hospital Veterinário Central - Portugal. O tumor apresentava 9 cm de diâmetro, não aderido, de consistência firme e ulcerado. Foi associada, após ressecção do nódulo, reconstrução com retalho de padrão subdérmico em H-plastia. Após 10 dias houve deiscência na porção medial do retalho, necessitando de nova intervenção cirúrgica. O laudo histológico revelou tricolemoma Istmico, neoplasia que apresenta o prognóstico bom, pois após a excisão cirúrgica raramente apresentam recidiva tendo efeito curativo.

The tricholemmoma is a benign neoplasm, rare in dogs, which originate from the outer sheath of the hair follicle root. This paper reports a case of tricholemmoma in the Serra da Estrela dog race, female and 9 years old, who came to be attended in the Central Veterinary Hospital - PT. The nodule had 9 cm of diameter, not joined, firm consistency and ulcerated. Was associated reconstruction with subdermal flap inH-plastia after ressection the nodule. It performed excision of the nodule and reconstructive surgery in Hplasty. After 10 days there was dehiscence in the medial part of the flap, requiring further surgical intervention. The histological report revealed tricholemmoma isthmic, neoplasm that presents a good prognosis because after surgical excision rarely suffer relapses with curative effect.

RESUMO

Intraoperative ultrasonography (IOUS) is used in medicine for diagnosis and guidance during oncologic surgery. The aims of this study were to assess the performance, feasibility, advantages and difficulties of the IOUS technique in dogs with suspected intra-abdominal tumors. The study included nine client-owed dogs that had suspected intra-abdominal tumors (spleen, liver or bowel) based on transabdominal ultrasound examination and that were subsequently referred for exploratory laparotomy surgery. During surgery, IOUS was performed; results of preoperative transabdominal ultrasonography, inspection by the surgeon and IOUS were compared on a case-by-case basis. IOUS was helpful in determining lesion resection in all cases. Lesions detected solely by the use of IOUS were observed in seven out of nine cases. Analysis of these cases demonstrated that IOUS can be a tool to assist during oncology surgery on the liver, spleen or bowel. Dogs with hepatic tumors can have small non-palpable intraparenchymal nodules, which may be visible by IOUS.(AU)

RESUMO

CASE SUMMARY: A 14-year-old, spayed female domestic shorthair cat was evaluated because of a right adrenal mass. The referring veterinarian had started treatment for hypokalemia and systemic arterial hypertension. During the initial evaluation the cat was alert and responsive, and serum potassium concentration was within the reference range. Serum concentrations of aldosterone and progesterone were increased. Atrophy of the contralateral adrenal and an exaggerated response of cortisol to stimulation with adrenocorticotropic hormone suggested hypersecretion of cortisol. Unilateral adrenalectomy was performed and recovery was uneventful. Histologic examination of the mass revealed an adrenocortical tumor. After surgery, clinical signs of hypercortisolism, hyperaldosteronism and hyperprogesteronism were no longer observed, and neither potassium supplementation nor antihypertensive treatment were needed. RELEVANCE AND NOVEL INFORMATION: In cases with an adrenocortical tumor, clinicians should investigate whether the tumor hypersecretes glucocorticoids, mineralocorticoids, sex steroids or combinations of these. Hypersecretion of more than one adrenal hormone may occur in a cat with an adrenocortical tumor.

RESUMO

Complete blood cell (CBC) changes are directly or indirectly related to cancer and have not been reported in bitches with mammary tumors. The aim of this study was to evaluate CBC changes in 161 bitches with mammary tumors, and to correlate them with disease progression. Normocytic and normochromic anemia and neutrophilic leukocytosis were observed and correlated with disease stages III, IV and V. In conclusion, anemia and leukocytosis may be correlated with advanced stages of mammary tumors in bitches.

As alterações no hemograma estão direta ou indiretamente relacionadas com câncer e são pouco descritas em cadelas com neoplasia mamária. O objetivo deste estudo foi analisar as alterações hematológicas em 161 cadelas portadoras de neoplasia mamária e correlacionar à progressão da doença. As principais alterações hematológicas encontradas foram anemia normocítica e normocrômica e leucocitose neutrofílica, sendo ambas mais frequentes em cadelas em estádio avançado (III, IV ou V) da doença.  Conclui-se que as alterações laboratoriais de anemia e leucocitose verificadas em cadelas com neoplasia mamária estão correlacionadas positivamente com o estádio avançado da doença.

RESUMO

BACKGROUND: The acute abdomen is any abdominal disorder resulting in pain, shock, or sepsis. Although it has a multifactorial etiology, the primary cause is gastrointestinal tract pathology. The aim of this study was to assess the contribution of abdominal ultrasound as a complementary diagnostic tool in non-human primates with an acute abdomen. METHODS: Three different non-human primates with clinical signs of acute abdomen were evaluated as follows: a chimpanzee (Pan troglodytes), a tufted capuchin (Cebus apella), and a black-tufted marmoset (Callithrix penicillata). RESULTS: Ultrasonographic examination assisted in the identification of a variety of differential diagnoses and was used in decision-making for exploratory laparotomy, which was performed in two animals. Ultrasound examination confirmed the source of the acute abdomen as the gastrointestinal tract in the three animals studied. CONCLUSIONS: Abdominal ultrasound is a useful technique for the investigation of signs of acute abdomen in non-human primates.

RESUMO

As proteínas de fase aguda (PFA) apresentam concentrações séricas alteradas mediante processos infecciosos, inflamatórios e neoplásicos. Objetivou-se com este trabalho avaliar as variações séricas das PFA em cadelas portadoras de neoplasia mamária, comparando com a avaliação histológica e leucograma. As PFA foram avaliadas em 45 cadelas com tumor de mama, distribuídas nos grupos neoplasia benigna (n=13), maligna não ulcerada (n=24) e maligna ulcerada (n=8). O grupo controle foi composto por 20 cadelas saudáveis. Foram realizados o teste de eletroforese em gel de poliacrilamida contendo dodecil sulfato de sódio (SDS-PAGE) para identificar as PFA (albumina, ceruloplasmina, transferrina, haptoglobina Hp, α-1 antitripsina e α-1 glicoproteina ácida) e o teste ultrassensível para proteína C reativa (PCR). As pacientes com neoplasia mamária maligna ulcerada apresentaram elevações sérica para PCR e Hp e redução da albumina (P<0,05, One-Way ANOVA e Teste de Dunn). Nessas pacientes, foi observada correlação positiva entre o leucograma inflamatório e o aumento das PFA (P=0,002, Teste de Fisher) e não foram observadas correlações entre as PFA e os subtipos histológicos. Conclui-se que avaliações conjuntas da PCR, Hp e albumina podem ser utilizadas como ferramenta de auxílio diagnóstico e prognóstico em cadelas com neoplasia mamária.

Acute phase proteins (APPs) are serum proteins whose concentrations change after infectious and inflammatory disease, and cancer. The aims of this study were to evaluate changes in APPs concentration and to correlate these findings with histological classification and WBC in female dogs with mammary tumors. APPs were studied in 45 female dogs with mammary tumor distributed in the following groups: benign (n=13), malignant without tumor ulceration (n=24), and malignant with tumor ulceration (n=8). SDS-polyacrylamide gel (SDS-PAGE) electrophoresis was used to measure APPs concentrations (albumin, ceruloplasmin, transferrin, haptoglobinHp, α-1-acid glycoprotein and α-1-antitrypsin) and ultrasensitive assay was used to evaluate serum C-reactive protein (CRP). Patients with malignant mammary neoplasia plus ulceration had significant increase of CRP and Hp, and had decreased levels of albumin (P<0.05, One-Way ANOVA and Dunn Test). Positive correlation among APPs and inflammatory leukocytosis were observed (P=0.002, Fisher test). No correlation was observed between APPs and histological subtype. In conclusion, combined changes of CRP, Hp and albumin may be used as a prediagnostic tool and prognosis in dogs with mammary tumors.

RESUMO

Background: Ectopic ureter is the most common cause of congenital urinary incontinence in dogs. Intramural ectopic ureter occurs when the ureter runs within the urinary bladder wall, while extramural ectopic ureter occurs when the distal ureter is not associated with the bladder wall. Ectopic ureters are diagnosed using different techniques and/or combinations of various imaging studies. Surgical correction is the standard treatment for dogs with an ectopic ureter, and these surgical techniques include neoureterostomy, ureteroneocystostomy, and nephroureterectomy. The aim of this report is to describe two cases of ectopic ureter successfully treated with surgery. Cases: In case 1, a 2-month-old female poodle, weighing 1.3 kg, with urinary incontinence since birth was presented to our veterinary service. Excretory urography revealed an ectopic ureter, and ureteroneocystostomy was performed. Abdominal ultrasonography performed 30 days after surgery revealed left renal pyelectasis and ureteral dilatation. Based on these findings, nephrectomy was performed. In case 2, a 3-month-old Golden Retriever, weighing 13.5 kg, with urinary incontinence since birth was brought to our veterinary service. Abdominal ultrasonography revealed a small left kidney and left ureteral dilation. Laparotomy was performed and revealed bilateral intramural ectopic ureters. Based on these findings, bilateral neoureterostomy was performed. Thirty days after surgery, patient presented with urinary infection that was controlled with antibiotics. Both dogs were continent one year after treatment. Discussion: Imaging results of the urinary tract can be useful in diagnosing ectopic ureter. Image modalities used for detecting ectopic ureter include excretory urography, pneumocystography, vaginography, retrograde urethrography, ultrasonography, computed tomography, and magnetic resonance imaging. The difference between extra and intramural ureteral ectopia, in some cases, can only be determined during exploratory laparotomy. Surgical complications vary due to several factors, such as whether the ureteral ectopia is uni- or bilateral, intra or extramural, and also the surgical treatment used. Ureteroneocystostomy complications include hydroureter, hydronephrosis, cystitis, transient stenosis, anastomotic dehiscence, persistent dysuria, and loss of normal ureteric peristalsis. Complications of neoureterostomy include persistent dysuria, cystitis, and reflex dyssynergia. Recanalization is a possible cause of postoperative incontinence if the distal ureter is not completely resected. Unilateral hydronephrosis was observed in the first reported case, and nephroureterectomy was performed. A nephroureterectomy is indicated when severe pathologic findings are present, such as severe hydronephrosis, hydroureter, or renal dysplasia and when the contralateral kidney and ureter are functioning normally. In the second case, bacterial cystitis was diagnosed during the post-operative period and was controlled with antibiotic therapy. After surgery, 44­67% of dogs had persistent urinary incontinence. Although residual incontinence can occur after incomplete intramural ureteral remnant or ureteral trough resection, incontinence has also been reported after ureteral reimplantation and nephroureterectomy. Bilateral disease and concurrent urogenital abnormalities often contribute to treatment failure. Therapeutic success was reported in both cases without signs of urinary incontinence one year after surgery.

RESUMO

Objetivou-se com este estudo analisar a acurácia do exame ultrassonográfico na definição da origem de neoplasias abdominais e avaliar a eficiência da técnica em sugerir a malignidade do processo. Em 24 pacientes de 113 animais avaliados pelo exame ultrassonográfico, foi observado massa e/ou entremeado nodular em diferentes órgãos da cavidade abdominal, classificados em tipo I, II, II(+) e III. Compararam-se os achados ultrassonográficos com a cirurgia e o exame histopatológico. A determinação da origem da massa foi correta em 20 (83 por cento) animais. Pelos dados estatísticos de acurácia de 91,67 por cento obtidos, acredita-se que o exame ultrassonográfico é interessante para se determinar previamente a malignidade, principalmente naqueles pacientes que apresentam lesões agressivas.

The aim of this study was evaluate efficacy of the ultrassonographic exam in the defining the location of the abdominal neoplasm and to estimate the accuracy of the method in screening the malignant neoplasm process. In 24 patients of 113 animals evaluated by the ultrassonographic exam it was observed a mass and/or a intermingled nodule in different organs in the abdominal cave, classified as type I, II, II(+) e III. It was compared the sonographic findings with surgical and histopathological analysis. The determination of the mass origin was correct in 20 (83 percent) animals and the percentage accuracy of malignant ultrasound determination was 91.67 percent. So, it is believed that the ultrasound is interesting to determine the malignancy in advanced cases, especially in those patients who have aggressive lesions.

RESUMO

A maioria das neoplasias do trato respiratório superior é maligna em gatos. O carcinoma de células escamosas é a neoplasia cutânea mais comum em felinos. O objetivo do tratamento cirúrgico é ressecar a neoplasia com ampla margem de segurança, bem como obter tecidos para realização de exame histopatológico. Os sinais clínicos apresentados pelos gatos acometidos podem mimetizar infecções crônicas do trato respiratório, sendo importante o diagnóstico diferencial. O objetivo desta revisão é demonstrar a simplicidade e as vantagens do procedimento cirúrgico de resseção bilateral do plano nasal, no tratamento das lesões causadas pelo carcinoma de células escamosas do plano nasal em felinos
