Broncopneumopatia eosinofílica em cães / Eosinophilic bronchopneumopathy in dog

Background: The eosinophilic bronchopneumopathy (EBP) is characterized by pulmonary infiltration with eosinophils. The etiology of canine EBP remains unclear, although hypersensitivity to aeroallergens is suspected. Dogs affected are usually young. The persistent cough is the most common clinical sign, often associated with respiratory difficulty and exercise intolerance. The diagnosis is based on signalment, radiographic and bronchoscopic findings, and the tissue eosiphilic infiltration demonstrated by cytology of bronchoalveolar lavage (BAL). No reports were found in Brazil. The aim of this paper is report four cases of canine BPE, with emphasis on clinical aspects, diagnosis and therapy.Cases: Case 1. A 18-month-old female dog with 12 kg of body weight was presented for consultation with a 60-day history of cough, inappetence and weariness. It presented cough and tachypnea. The complementary exams demonstrated peripheral eosinophilia, bronchointersticial pulmonary pattern on radiography, moderate amount of mucus on bronchoscopy and tissue eosinophilis infiltration on the BAL. The treatment was based on steroids, with improvement of clinical signs. Case 2. A 24-month-old female dog with 16 kg of body weight was presented for consultation with one-year history of cough, inappetence and lethargy. It presented only cough, and in complementary exams showed transitory peripheral eosinophilia, bronchointersticial pattern on radiography and predominantly eosinophilic inflammation on citology of BAL. The therapy was based on steroids, with improvement followed by worsening of signs, with need of readjustment of doses. Case 3. A 8-year-old male dog with 6.2 kg of body weight was presented for consultation with 3-weeks history of productive cough, vomiting and weight loss. The complementary exams showed peripheral eosinophilia, bronchointersticial pulmonary pattern on radiography and eosinophils infiltration on cytology of BAL.[...]

Morfologia da traqueia e lobação pulmonar de Leopardus pardalis (jaguatirica) / Morphology of the trachea and lung lobation of Leopardus pardalis (ocelot)

A espécie Leopardus pardalis, conhecida popularmente como jaguatirica, é um felino de médio porte com ampla distribuição em território nacional e está incluída na lista de espécies da fauna brasileira ameaçadas de extinção. Este estudo teve como objetivo caracterizar os aspectos macroscópicos e microscópico da traqueia e lobos pulmonares em L. pardalis. As análises foram feitas utilizando cinco exemplares de jaguatirica, sendo dois machos e três fêmeas, adultos, três desses exemplares foram a óbito por atropelamento em rodovias próximas ao município de Alta Floresta, e dois doados após a morte pelo IBAMA ao o Laboratório de Zoologia e Morfologia Animal. Nos espécimes a traqueia era um tubo flexível formado por pares de arcos cartilaginosos, apresentando epitélio pseudo-estratificado não ciliado no seu revestimento interno, e outros estruturas básicas deste órgão. O pulmão se mostrou como um órgão constituído por lobos separados por fissuras com um parênquima usual aos demais mamíferos descritos. No que diz respeito às caraterísticas anatômicas da traqueia e pulmão se mostraram semelhantes à de outros mamíferos, já nos aspectos microscópicos da traqueia apresentou certas peculiaridades diferindo dos demais trabalhos encontrados. No que tange o aspecto do parênquima pulmonar as características histológicas não variaram com as que estão descritas.(AU)

The species Leopardus pardalis, popularly known as ocelot, is a medium sized cat with wide distribution in the national territory and is included in the list of species of Brazilian fauna threatened with extinction. This study aimed to characterize the macroscopic and microscopic aspects of the trachea and lung lobes in L. pardalis. Analyses were performed using five copies of ocelot, two males and three females, adults, three of these specimens died from being run over on highways nearby the municipality of Alta Floresta, and two donated after death by IBAMA to the Laboratory of Zoology and Animal Morphology. In the trachea specimens was a flexible tube formed by pairs of cartilaginous arches, with pseudo-stratified epithelium ciliated not in its inner lining, and other basic structures of this body. Lung proved as a body made up of lobes separated by cracks with a usual parenchyma to the other described mammals. With respect to the anatomic features of the trachea and lung were similar to other mammals, as in the microscopic aspects of the trachea showed certain peculiarities found differing from the other jobs. Regarding the appearance of the lung parenchyma histological characteristics did not differ with those described.(AU)

Pneumonia por Klebsiella pneumoniae em potro Relato de Caso

Pneumonias são afecções graves que se caracterizam pela inflamação do parênquima pul­monar, estando frequentemente associada à inflamação dos brônquios, bronquíolos e pleura. As causas são variáveis, podendo ser viral, bacteriana, fúngica, parasitária, falhas imunológicas e iatrogênicas. Os potros são frequentemente acometidos, sendo esta enfermidade considera­da a causa mais importante de morbidade e mortalidade em potros com mais de um mês de vida. A sintomatologia está diretamente ligada ao grau de lesão do parênquima pulmonar.

Neumonía en Organización: revisión del tema y presentación de 4 casos / Organizing pneumonia: revision of the topic and presentation of 4 cases

Se hace una revisión de las Neumonías en Organización según el concepto actual de las mismas, su nomenclatura diferente de las usadas previamente (BOOP), y las características clínicas, clasificación etiológica, alteraciones funcionales y anormalidades en las imágenes. Se comentan 4 casos clínicos de interés, dos con confirmación biópsica, y dos debidos a toxicidad por amiodarona. Se describe la afectación clínica, funcional y radiológica de los casos y se enfatiza un paciente con alteración tomográfica inusual y otro con evolución fibrótica progresiva asociado a artritis reumatoidea que se hizo aparente un año después del COP y coincidió con una exacerbación tardía del mismo.

Organizing pneumonias are reviewed according to the new approach from ATS/ERS statement. Most frecuent clinical patterns, image studies and functional alterations are commented on. Four clinical cases are described, two with pathological confirmation and two other amiodarone related. Unusual HRTC presentation is remarked in one case and another one due to rheumatoid arthritis, with pulmonary alteration preceding in one year rheumatic manifestations and relapsing one year later simultaneously with clinical and serologic rheumatoid arthritis.
