OBJECTIVE: to review the evolution of acute respiratory distress syndrome (ARDS) definitions and present the current definition for the syndrome. DATA SOURCE: a literature review and selection of the most relevant articles on ARDS definitions was performed using the MEDLINE®/PubMed® Resource Guide database (last ten years), in addition to including the most important articles (classic articles) that described the disease evolution. DATA SYNTHESIS: the review included the following subjects: introduction; importance of definition; description of the first diagnostic criterion and subsequently used definitions, such as acute lung injury score; definition by the American-European Consensus Conference, and its limitations; description of the definition by Delphi, and its problems; accuracy of the aforementioned definitions; description of most recent definition (the Berlin definition), and its limitations; and practical importance of the new definition. CONCLUSIONS: ARDS is a serious disease that remains an ongoing diagnostic and therapeutic challenge. The evolution of definitions used to describe the disease shows that studies are needed to validate the current definition, especially in pediatrics, where the data are very scarce.

A estenose congênita da abertura piriforme é uma rara causa de obstrução nasal que pode ocorrer no recém-nascido. É provocada pelo crescimento excessivo do processo nasal medial da maxila causando um estreitamento do terço anterior da fossa nasal. Inicialmente foi relatada uma deformidade isolada, posteriormente a estenose congênita da abertura piriforme foi considerada como apresentação de forma menor da holoprosencefalia. Neste artigo relatamos um caso de recém-nascido do sexo masculino que apresentava desde o parto dispnéia, cianose e episódios de apnéia. O paciente foi submetido a cirurgia com alargamento da abertura piriforme por acesso sublabial. No seguimento apresentou boa evolução durante o acompanhamento. O relato desta deformidade mostra sua importância como causa de obstrução nasal congênita e diagnóstico diferencial de atresia coanal. A estenose congênita da abertura piriforme pode ser reparada adequadamente, quando necessário, através de procedimento cirúrgico.

Doenças congênitas e adquiridas das vias aéreas podem causar dispnéia e estridor em crianças. Nas UTIs tem-se registrado maior sobrevida de prematuros, porém também elevada incidência de complicações relacionadas à intubação. OBJETIVO: Analisar retrospectivamente os achados endoscópicos em crianças com estridor. TIPO DE ESTUDO: Corte transversal. MATERIAL E MÉTODOS: Foram revisados 55 prontuários de crianças com estridor, submetidas aos exames endoscópicos de janeiro de 1997 a dezembro de 2003. Endoscopias foram: estridor pós-extubação (63,63%) e avaliação de estridor neonatal (21,82%). Observou-se alto índice de doenças associadas, como pulmonares (60%), neurológicas (45,4%) e DRGE (40%). Os principais achados endoscópicos e as indicações de traqueotomia foram: estenose subglótica (27,27%) e processos inflamatórios das vias aéreas (21,82%), principalmente em crianças com menos de cinco anos. Lesões congênitas foram mais freqüentes em crianças com menos de um ano. CONCLUSÕES: O estridor na infância possui múltiplas etiologias, sendo as relacionadas à intubação traqueal as mais freqüentes em hospitais com atendimento de doenças complexas. Pediatras e otorrinolaringologistas devem conhecer as causas de estridor, realizando avaliação clínica detalhada para determinar a gravidade do caso. O exame endoscópico deverá ser minucioso e detalhado.

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.

Surgery on the head and neck region may be complicated by vascular trauma, caused by direct injury on the vascular wall. Lesions of the arteries are more dangerous than the venous one. The traumatic lesion may cause laceration of the artery wall, spasm, dissection, arteriovenous fistula, occlusion or pseudoaneurysm.We present a case of a child with a giant ICA pseudoaneurysm after tonsillectomy, manifested by pulsing mass and respiratory distress, which was treated by endovascular approach, occluding the lesion and the proximal artery with Histoacryl. We reinforce that the endovascular approach is the better way to treat most of the traumatic vascular lesions.

Linfoma multicêntrico foi diagnosticado em um cão com dois anos de idade que apresentava insuficiência respiratória, aumento de volume abdominal (ascite) e linfoadenopatia generalizada. O exame imunoistoquímico revelou origem de células T com expressão CD3+ e CD79-. Após cinco semanas, o cão apresentou déficits neurológicos progressivos, sendo identificada a presença de linfócitos neoplásicos no líquor. O exame histopatológico demonstrou invasão de células neoplásicas no baço, linfonodos, cérebro e cerebelo.

Urolithiasis is a disease that despite being a commonly observed problem in veterinary practice is uncommon in birds. Such disease was not reported in passeriforms to date. Accordingly, the aim of the present article is to describe a case of urolithiasis in an adult female lesser seed finch (Sporophila angolensis) pet bird which presented abdominal distension, respiratory distress, and apathy prior to death. The bird had history of being fed with a diet rich in protein. After the bird death, a necropsy was conducted in order to determine the cause of death. At necropsy, accentuated ascites, hydropericardium, and ureteral stones in the left ureter could be grossly observed. Additional tests related with viral and bacterial microbiological testing and with the determination of calculi composition could not be performed since the owner did not consent with the procedures because of the cost. Since the bird was fed on a high protein diet, a relationship between the ureteroliths and dietary imbalance was suggested with participation of protein in calculi development by providing the organic nuclei. Additionally, we conclude that the presence of calculi in the ureter resulted in urinary flow blockage, ascites, and consequent acute respiratory failure due to filling of air sacs with liquid.

Os nódulos vocais são causas freqüentes de disfonias infantis, porém, através das vídeoendoscopias, outras lesões têm sido diagnosticadas na laringe infantil, como os cistos, sulcos, pontes e micromembranas, denominadas de lesões estruturais mínimas. OBJETIVO: Avaliar, em 71 crianças com disfonia agendadas nos ambulatórios de Foniatria da Faculdade de Medicina de Botucatu (Unesp) nos últimos cinco anos: sexo, idade, diagnósticos, tratamentos e evolução clínica. FORMA DE ESTUDO: Clínico retrospectivo. CASUÍSTICA E MÉTODO: Realizou-se estudo retrospectivo das avaliações otorrinolaringológicas e endoscópicas de 71 crianças com queixas de disfonia e idade entre 3 a 13 anos (45 meninos e 26 meninas). As crianças haviam sido submetidas a exame endoscópico com telescópio rígido ou nasofibroscópio flexível. Foram excluídas as crianças com disfonias funcionais ou com queixas de obstrução respiratória. RESULTADOS: Os principais diagnósticos foram: nódulo vocal (47 casos; 66,2%), cisto epidérmico (7 casos; 9,9%), cisto aberto fistulizado (6 casos; 8,4%), sulco vocal (5 casos; 7,1%), ponte + cisto (2 casos; 2,8%), micromembrana anterior (2 casos; 2,8%) e pólipo vocal (2 casos; 2,8%). As disfonias foram mais freqüentes entre os meninos (63,3%). A fonoterapia isolada foi o tratamento de escolha nos casos de nódulo vocal (evolução favorável), sulco vocal (evolução desfavorável) e micro-membrana (evolução desfavorável). Nas demais lesões (cistos, pontes e pólipos) o tratamento de escolha foi a cirurgia associada à fonoterapia, com resultados satisfatórios, exceto nos casos que recusaram a cirurgia. CONCLUSÃO: Os nódulos vocais são as principais causas de disfonias em crianças, porém as lesões estruturais mínimas mostraram-se também freqüentes, exigindo exame minucioso para o diagnóstico.

Calves aged 3 mth were readily infected with oocysts and cysts of Toxoplasma gondii administered by the oral route. Fever, respiratory distress, nasal discharge, and hyperemia of the conjunctivas were the most significant clinical signs noted in the infected animals. Parasitemia was demonstrated in all infected calves. It occurred on different days and up to 62 days after the infection. Toxoplasma was demonstrated in tissues of all infected calves, and the organ most frequently parasitized was the lymph node. Parasitism of the retina was demonstrated in 2 calves. All infected animals had antibody against T. gondii in their serum. The Sabin-Feldman dye test and the indirect immunofluorescent test were both useful in detecting antitoxoplasma antibody.
