Edema pulmonar agudo associado à endocardite bacteriana em um filhote de Boxer – Relato de caso

Revista de Educação Continuada em Medicina Veterinária e Zootecnia do CRMV-SP (2013)

A. J. Bendas Bruno Alberigi

A endocardite bacteriana (EB) e causada por infeccao microbiana do endotelio valvular. A EB pode ocorrer subitamente sendo letal em poucos dias ou evoluir de forma lenta por semanas a meses. O requisito para que ocorra e endocardite e a bacteremia que pode ter origem em diversos orgaos e tecidos. Em caes, o lado esquerdo e mais atingido, sendo a valva mitral a mais acometida. Os sinais clinicos estao relacionados a valva afetada, podendo variar de assintomaticos a portadores de insuficiencia cardiaca congestiva (ICC). O diagnostico e realizado atraves de ecocardiografia associada a hemocultura, que nao e um exame de rotina na medicina veterinaria. A lesao caracteristica de necropsia sao lesoes vegetativas nas valvas cardiacas e endocardio. Relato de Caso: Um canino, femea, da raca Boxer, quatro meses, esquema vacinal finalizado ha uma semana, foi encaminhado para emergencia com sintomatologia clinica de dispneia de inicio agudo. Ao exame clinico apresentava mucosas hipocoradas, secrecao nasal sero-sanguinolenta, sopro sistolico em foco mitral e ausculta pulmonar revelando importante crepitacao difusa compativel com edema pulmonar. Foi realizado acesso venoso, iniciando-sefurosemida venosa (4mg/kg). Apos 20 minutos, nao houve melhora no padrao respiratorio aumentando-se a dosagem para 6mg/kg. Apos 15 minutos, o animal apresentou parada cardiorrespiratoria, nao havendo exito na reanimacao. O animal foi encaminhado para necropsia. Resultados/ Discussao: A necropsia revelou hidrotorax, hidropericardio, endocardite atrial esquerda associada a mineralizacao difusa, degeneracao acentuada de valva mitral e edema pulmonar acentuado e difuso. A suspeita inicial foi edema pulmonar secundario a cardiopatia. A secrecao nasal sero-sanguinolenta normalmente esta relacionada a edema pulmonar grave. Iniciou-se protocolo diuretico com furosemida, que e a droga de eleicao. Pelo resultado da necropsia conclui-se que a causa do obito foi edema pulmonar relacionado a degeneracao importante da valva mitral por endocardite. Provavelmente bacteremia nao se encontrava ativa, pois nao foram encontradas bacterias nas lesoes, porem a lesao valvar mineralizada permaneceu. Conclusao: O presente trabalho mostra a importância do exame fisico, provavelmente havia sopro mitral desde a epoca vacinal, que se houvesse sido detectado precocemente poderia ter aumentado a sobrevida do paciente.

Pulmonary stenosis in a dog submitted to valvuloplasty

DOAJ (DOAJ: Directory of Open Access Journals) (2019)

Bruno Alberigi Nathália Marques de Oliveira Lemos Nicole Vallejo Correa dos Santos Julielton de Souza Barata Alexandre José Rodrigues Bendas

The Congenital heart diseases are characterized by morphological defects in the embryonic development and the most frequent in dogs are: pulmonary and aortic valve stenosis, ventricular septal defect and persistente ductus arteriosus. They may occur asymptomatically or even evolve to congestive heart failure. The definitive diagnosis is made through the visualization of the alterations in the echocardiogram. In the present report, a French Bulldog, three month old, asymptomatic was presented to a private Veterinary practice in Rio de Janeiro, Brazil. Cardiac auscultation evidenced a systolic heart murmur in tricuspid focus and diastolic murmur in pulmonary focus. To better evaluate the dog chest radiography, electrocardiogram and echocardiogram were perfomed and allowed the diagnosis of pulmonary stenosis. The clinical treatment with beta-blocker was installed and the surgical procedure was performed with the ballon valvuloplasty. The aim of this study was to report a case of pulmonary artery stenosis in a puppy, treated clinically and surgically, emphasizing the importance of the physical and complementary cardiological exams.

Platynosomum illiciens infection in domestic cats: insights from a sanctuary

Brazilian Journal of Veterinary Medicine/Revista Brasileira de Medicina Veterinária (2023)

Bruno Alberigi Mateus Daudt Matos Thaís Ribeiro Correia Bruno de Oliveira Telles Ferreira Lais Sperandio Cassani

Platynosomum illiciens, a trematode parasite known for its intricate life cycle, predominantly infests the liver, gallbladder, and bile ducts of domestic cats. In this study, we examined feline fecal samples from a cat sanctuary in Metropolitan Rio de Janeiro, Brazil, aiming to determine whether, even in such environments, cats retain their atavistic hunting habits, as evidenced by the presence of P. illiciens in fecal samples. The infection diagnosis utilized centrifugal sedimentation in the formalin-ethyl acetate test. Out of 72 fecal samples collected from various cats, four tested positive for P. illiciens eggs. This study serves as a reminder that even in environments where they are well-fed, cats exhibit predatory behavior, engaging in hunting and consuming prey, thus exposing themselves to parasites. It emphasizes the importance of veterinarians and cat caretakers being cognizant of the widespread presence of P. illiciens in Brazil and considering it in the differential diagnosis for cats presenting with liver or gallbladder issues. In conclusion, our findings underscore that the ancestral instinct for hunting and predation, preserved in domestic cats, persists despite fulfilling their nutritional needs.

Adrenocortical carcinoma in a West White Terrier: clinical and diagnostic approach

Brazilian Journal of Veterinary Medicine/Revista Brasileira de Medicina Veterinária (2024)

Fernanda de Paula Sesti Gabriel Marchiori Gonzaga Flávia Maria Tavares Manoel Zimmer Tatiane Viana de Souza Cruz Bruno Alberigi

Adrenocortical carcinoma (ACC) is a rare condition in dogs. This type of tumor can be functional, hormone-producing, or nonfunctional. Bilateral adrenal tumors are uncommon, whereas unilateral adrenal tumors are more prevalent. Abdominal ultrasonography is crucial for detecting these lesions, which are characterized by heterogeneous parenchymal characteristics. Furthermore, elastography, a technique that assesses tissue stiffness, is useful for differentiating between malignant and benign lesions. This paper describes a case of ACC in a West Highland white terrier. The dog initially presented with dermatological changes and increased adrenal tissue stiffness, as detected by elastography. After additional examinations, including computed tomography, an adrenalectomy was successfully performed. Histopathological analysis confirmed the diagnosis of ACC. Post-surgical follow-ups included periodic ultrasonography to monitor the remaining adrenal gland. A nodular lesion was identified in the left adrenal gland during the follow-up, highlighting the importance of continuous monitoring. This case underscores the significance of an integrated approach, from the initial evaluation to the post-treatment follow-up for the effective management of ACC in dogs.

Tromboembolismo pulmonar secundário a anemia hemolítica imunomediada em um cão com leptospirose – relato de caso.

Revista de Educação Continuada em Medicina Veterinária e Zootecnia do CRMV-SP (2013)

Bruno Alberigi A. J. Bendas Juliana Pereira Alejandro Caballero Rodrígues D. R.B Silvano

A leptospirose e uma doenca infecciosa causada por uma espiroqueta do genero Leptospira que pode levar a destruicao imunomediada de eritrocitos, fenomeno conhecido como anemia hemolitica imunomediada (AHIM). A presenca de tromboembolismo pulmonar e sistemico tem sido detectada em 29 a 32% dos caes com AHIM, com taxa de letalidade de 70%. O presente trabalho tem o objetivo de relatar um cao com leptospirose e AHIM que desenvolveu TEP. Relato de Caso: Um canino, macho, da raca Akita, oito anos, foi atendido com historico de prostracao, e trombocitopenia persistente, apresentava mucosas hipocoradas e prostracao. O hemograma revelou VG 12%, leucometria normal; creatinina 1,7 mg/dL, ureia 157 mg/dL, Fosfatase alcalina 132 mU/dL e ALT 113 mU/dL. Foi realizada ELISA para Erlichiacanis, sendo o resultado negativo. Foi realizada hemotransfusao. Dois dias apos, apresentou ictericia, ALT 1024 mU/dL, fosfatase alcalina 164 mU/dL, e aumento das bilirrubinas. O exame ultrassonografico revelou hepatopatia difusa, esplenomegalia, e perda de relacao cortico medular de ambos os rins. Realizou-se sorologia para leptospirose sendo reagente na titulacao de 1:400, foi iniciada penicilina G. O animal apresentou dispneia, sendo realizada radiografia toracica que revelou bronquite cronica discreta, o hemograma revelou presenca de VG de 14% com 0,2 % de reticulocitos, leucometria 20.000 n/μL; plaquetas normais; creatinina 0,3 mg/dL, ureia 63 mg/dL. Em 48horas o animal veio a obito e na necropsia constatou-se presenca de trombo de 7cm em arteria pulmonar. Discussao: A ictericia pode ser decorrente tanto de necrose celular hepatica como hemolise, no caso relatado acredita-se que ocorreram ambas as situacoes, devido as alteracoes de imagem hepaticas e pela anemia acentuada. A AHIM pode ter sido agravada por reacao de hemolise pos-transfusional. Acredita-se que nessa situacao o sistema imunologico do paciente ja estava altamente sensibilizado pela presenca do antigeno da Leptospira. A dispneia apresentada pode ser resultante da hipoxia pela anemia ou formacao de microtrombos obstruindo o leito vascular pulmonar. O presente trabalho mostra a importância da investigacao de disturbios de coagulacao em pacientes com leptospirose, realizando-se medidas profilaticas que evitem o tromboembolismo.

Clinical, electrocardiographic and echocardiographic profile of dogs with chronic degenerative mitral valve disease, treated at a private service of cardiology and respiratory diseases

Revista Brasileira de Ciência Veterinária (2023)

Mário dos Santos Alicia da Silva Bento Nathália Marques de Oliveira Lemos Karen Denise da Silva Macambira Bruno Alberigi

Chronic degenerative mitral valve disease is the most common acquired heart disease and the main cause of congestive heart failure (CHF) in middle-aged to elderly dogs, being more frequent in small and miniature breeds, being rare in breeds of medium to large size.This disease is characterized by nodular deformity of the valve leaflets, as well as thickening and, in some cases, distension of the chordae tendineae.Echocardiographic findings include cardiomegaly, thickening of the atrioventricular valves, valve insufficiency and myocardial dysfunction, which, in turn, become more common with the progression of the disease.According to the consensus of the American College of Veterinary Internal Medicine, endocardiosis can be classified into stages, according to its clinical evolution.The objective of the present study was to determine the clinical, electrocardiographic, radiographic and echocardiographic profile of dogs with chronic degenerative mitral valve disease in a cardiology service between the years 2017 to 2022.The selected animals were those whose diagnoses involved valve alteration with association with echocardiographic evaluation.The data obtained were compiled in Microsoft Excel® spreadsheets and evaluated using descriptive statistics and Pearson's correlation using the BioEstat® software.Through the observations and results obtained, it was possible to relate that the hypothesis of the correlation between the severity of clinical signs and the exacerbation of the structural alteration of the heart valves may be indicators of a worse prognosis for the evolution of chronic degenerative mitral valve disease.

Study of the heart rate variability in dogs with brachycephalic syndrome submitted to rhinoplasty surgery

DOAJ (DOAJ: Directory of Open Access Journals) (2020)

Mário dos Santos Filho Daniel Carvalho Hainfellner Nathália Marques de Oliveira Lemos Karen Denise da Silva Macambira Juliana Silva do Carmo

The aim of the present study was to evaluate the HRV in the brachycephalic races, before and after surgical correction of the stenosis of the nostrils, by means of prolonged electrocardiography, observing the excess of the parasympathetic stimulation regarding the occurrence of bradyarrhythmias and their clinical consequences, and possibility of improvement of the autonomic balancing after the treatment, increasing the quality and life expectancy of these patients. Sixteen dogs with nostril stenosis were included, where the analysis and progression of the HRC findings at different moments before the surgical procedure (day 0) and after the procedure were performed in two moments, 30 and 60 days. The technique of alavestibulplasty was performed and HRV analysis was recorded by means of prolonged electrocardiography. For this examination, the indexes were analyzed in the time domain. Regarding the clinical findings, there was an improvement in the evaluation of the heart and respiratory rate, as well as a reduction in parasympathetic activity, as shown in the bradyarrhythmias. Regarding the HRV indexes in the time domain, rMSSD and SDNN associated with mean heart rate findings, have brought strong indications that the reduction of parasympathetic stimulation is related to the reduction of HRV in these animals. The rMSSD is the HRV index in the domain of the time that early changed can be used as indicator of the increase of the parasympathetic activity caused by the Brachycephalic Syndrome

Evaluation of the right ventricular function in dogs with brachycephalic syndrome before and after rhinoplasty

Brazilian Journal of Veterinary Medicine/Revista Brasileira de Medicina Veterinária (2021)

Daniel Carvalho Hainfellner Mário dos Santos Bruno Alberigi Alexandre José Rodrigues Bendas Carolina do Valle Aben Athar

Brachycephalic dogs are usually affected by primary and secondary anatomical changes in the airways that contribute to the brachycephalic syndrome. Chronically, these changes contribute to an increase in pulmonary arterial pressure and right cardiac overload (cor pulmonale). The right cardiac function in 17 dogs with brachycephalic syndrome was assessed using echocardiography before, and at 30 and 60 days after rhinoplasty. The maximum pulmonary systolic flow velocity, the pressure gradient between the AP and RV (GrFP), the right ventricular systolic function (tricuspid ring systolic excursion (TAPSE), the variation of the right ventricular area (FAC), the velocity of the systolic displacement of the right ventricular myocardium (S’) by tissue Doppler) and right ventricular diastolic function (transtricuspid flow and the relationship between the E and A waves, evaluation of the E’ and A’ waves using tissue Doppler of the free wall of the right ventricle) were evaluated. The right ventricular fractional area, velocity, and pressure gradient of pulmonary arterial flow showed the best sensitivity in these analyses. The present study reinforces the concept that obstructions in the anterior airways contribute to pulmonary hypoxia. However, the correction of these obstructions proved to be beneficial in the reduction of right heart overload.

Medicina Veterinária (UFRPE) (2019)

Mário Santos Filho Daniel Carvalho Hainfellner Bruno Alberigi Nathália Marques Oliveira Lemos Juliana Silva do Carmo

A bronquite crônica é uma doença de alta ocorrência em cães. Sua etiologia é associada a causas alérgicas e/ou infecciosas, levando a irritação das vias aéreas, acúmulo de muco e sinais clínicos como a tosse produtiva. O diagnóstico baseia-se nos achados clínicos e radiográficos. Para descartar processo infeccioso, é indicado lavado brônquio-alveolar, com realização de citologia e cultura microbiológica. O protocolo terapêutico já estabelecido na clínica de pequenos animais, associado ao manejo complementar se tronam ferramentas imprescindíveis para resolução de casos mais complicados. O presente trabalho teve como objetivo estabelecer uma revisão bibliográfica sobre a bronquite crônica canina, baseando-se nos achados clínicos e estudo epidemiológico para o correto diagnóstico, tratamento e manejo.
