In otorhinolaryngologist's experience the nasal out-breath of people affected by chronic nasal or paranasal infections may be characterized by peculiar odours. In a previous study we showed that an electronic nose (EN), examining nasal out breath was able to distinguish subjects affected by chronic rhinosinusitis from healthy subjects. The present study is aimed at analysing the intensity and the quality of the odorous components present in the air expired by patients affected by rhinosinusitis, using a new EN based on gas-chromatography and surface acoustic wave analysis. In the gas-chromatographic tracings of the pathologic subjects there were six peaks, which were not present in control group cases. These peaks correspond to odorous components, whose chemical composition ranges from C6 to C14. Peaks obtained were compared with other tracings revealed from specific bacterial and fungal cultures analyses and we appreciated some analogies.

RESUMOLipomas são tumores freqüentes no tecido subcutâneo, de crescimento lento e benigno, podendo ser encontrados em tecidos mais profundos, como os músculos, órgãos abdominais e torácicos, na cavidade oral e no crânio. Este relato descreveu um caso de lipoma em um papagaio-verdadeiro, mantido em cativeiro na região de Fernandópolis, SP. O animal, de aproximadamente 10 anos de idade e 485 gramas, apresentava dificuldade de locomoção devido ao grande aumento de volume, progressivo há alguns meses e localizado na região adcloacal direita. Não foram evidenciadas alterações comportamentais ou na ingestão de alimentos ou água. À palpação, o nódulo apresentava consistência macia e pequenas áreas crostosas cutâneas. Foi conduzido o exame radiográfico e biópsia aspirativa com agulha e o animal foi submetido à cirurgia para exérese do nódulo, sendo realizada indução anestésica intra-muscular com diazepam e cetamina e manutenção por isoflurano. No período pósoperatório foram realizadas aplicações de antibiótico, antiinflamatório e analgésico. O nódulo extraído pesou 62 gramas, correspondendo a 12,8% do peso corpóreo, e foi processado histologicamente, revelando a presença de adipócitos bem definidos, com citoplasma desenvolvido e núcleos periféricos. ABSTRACTLipomas are usual tumors on subcutaneous tissue and present slow and benign development, occurring even in deep tissues, as muscles, abdominal and thoracic organs, the oral cavity and the skull. This report described a case of lipoma in a blue-fronted parrot, kept in captivity in Fernandópolis, SP, area. The around 10 year-old animal weight 485 grams and presented difficulty for locomotion due the enormous volume of the mass, which was progressively during the last months and was situated on the right adcloacal region. There were no behavior, feeding or drinking changes. By palpation, the nodule presented soft aspect and several skin lesions. Radiographic examination and aspirative needle biopsy were performed and the animal went for surgery for nodule exeresis, by using intramuscular anesthesic induction with diazepam and ketamine and manutention by isofluorane. Antibiotics, anti-inflammatory and analgesics were administered on postoperative time. The nodule weighted 62 grams, corresponding to 12.8% of the body weight, and histologically demonstrated the presence of well defined adipocites, with large cytoplasm and peripheral nuclei.
ResumoA síndrome vestibular é uma afecção bem descrita em animais domésticos e pouco relatada em selvagens. Este relato descreveu essa afecção de origem central em uma fêmea adulta de tamanduá-bandeira (Myrmecophaga tridactyla), caquética, apresentando deambulação em círculos, hipermetria extensora nos membros torácicos, desvio da cabeça e nistagmo espontâneo horizontal e posicional vertical. O animal foi alimentado por sonda oral, 2x/dia e instituiu-se tratamento com dexametasona subcutânea na dose 6mg/kg, 1x/dia, com melhora progressiva a partir da segunda administração. A dose foi diminuída pela metade do quarto ao sexto dia, e reduzida novamente à metade no sétimo dia, quando ocorreu óbito. Entretanto, no quinto dia de tratamento, a deambulação em círculos foi interrompida, e a hipermetria, desvio da cabeça e nistagmo diminuídos. O tratamento de animais selvagens com síndrome vestibular é um desafio e é prejudicado pela hiporexia ou anorexia, dificultando a recuperação dos mesmos, que geralmente apresentam diminuição da massa muscular. Palavras-chave: Síndrome vestibular, tamanduá-bandeira, Myrmecophaga tridactyla AbstractThe vestibular syndrome is a well-defined disease in domestic animals but little known in wild ones. Here this affection of central origin is described in a caquetic adult female giant anteater (Myrmecophaga tridactyla), which presented circling behavior, extensor hypermetry in thoracic limbs, head tilt and spontaneous horizontal and positional vertical nystagmus. The animal received tube feeding twice daily and dexamethasone was given subcutaneous once daily at the dosis of 6mg/kg, with a progressive improvement of health after the second day of treatment. Dose was reduced to a half from fourth to sixth day, and to a quarter on seventh day, when the animal died. On the fifth day, however, circle deambulation had ceased and hypermetry, head tilt and nystagmus were reduced. Treating vestibular syndrome is a challenge in wild animal practice. Treatment is affected by hyporexia and anorexia, making difficult the animals´ health improvement, which generally present muscle atrophy.
