RESUMO
Tracheal luminal stenosis can cause clinical respiratory distress in wild birds. We describe a case of tracheal stenosis due to diffuse ossification with osteopetrosis of tracheal rings in a yellow-crowned parrot (Amazona ochrocephala) with a history of chronic respiratory distress and death after development of marked dyspnoea. An ante-mortem radiographic examination revealed that the tracheal rings were radiopaque and that there were multiple areas of osteopenic change in long bones. At necropsy, there was stenosis of the tracheal rings characterized by complete replacement of cartilage by thickened compact bone with osteopetrosis and bone necrosis. The clinical respiratory distress and death of the parrot were associated with tracheal luminal stenosis due to thickening of the tracheal rings by diffuse ossification with osteopetrosis.

Objective. To stablish the electrocardiographic parameters of individuals of the species Amazona ochrocephala, from the Unidad de Rescate y Rehabilitacion de Animales Silvestres at the Universidad Nacional de Colombia. Materials and methods. The electrocardiographic examination was performed under inhaled anesthesia with isoflurane. Leads I, II, III, aVL, aVR and aVF were measured. Results. Electrocardiographic parameters obtained in Lead II. P wave Duration: 0.015-0.044 s, P wave amplitude: 0.031 to 0.6 mv, R wave duration: 0.015-0.022 s, amplitude R: 0.034-0.038 mv, S wave Duration: 0.019- 0.042 s, amplitude S: 0.194-0.815 mv, T wave Duration: 0.025-0.064 s, T-wave amplitude: 0.010 to 0.5 mv, PQ Duration: 0.021-0.076 s, QRS Duration: 0.036-0.068 s, QT Duration: 0.070-0.015 s, RR Duration: 0.104-0.324 s, EEM: -111° to -80°, FC: 240-600 ppm. Conclusions. The results showed different values for amplitude and duration of the P, R and T waves in comparison to those obtained in other studies. However, they were similar for heart rate, MEA and duration of the PQ/R, QT and QRS segments.
Objetivo. Establecer los parámetros electrocardiográficos en individuos de la especie Amazona ochrocephala, de la Unidad de Rescate y Rehabilitación de Animales Silvestres de la Universidad Nacional de Colombia sede Bogotá. Materiales y Métodos. El examen electrocardiográfico se realizó bajo anestesia inhalada con Isoflurano. Se tomaron derivadas I, II, III, aVL, aVR y aVF y posterior medición de ondas e intervalos usando magnificación con lupa. Resultados. Parámetros electrocardiográficos de la segunda derivada. Duración onda P: 0.015-0.044 s, amplitud onda P: 0.031-0.6 mv, duración onda R: 0.015-0.022 s, amplitud R: 0.034-0.038 mv, Duración onda S: 0.019- 0.042 s, Amplitud S: 0.194-0.815 mv, Duración onda T: 0.025-0.064 s, Amplitud onda T: 0.010-0.5 mv, Duración PQ: 0.021-0.076 s, Duración QRS: 0.036-0.068 s, Duración QT: 0.070-0.015 s, Duración R-R: 0.104-0.324 s, EEM: -111° a -80°, FC: 240-600 ppm. Conclusiones. Los resultados mostraron valores diferentes para los rangos de amplitud y duración de las deflexiones P, R y T en comparación a los obtenidos en otros estudios pero similares en cuanto al rango de frecuencia cardiaca, EEM y a la duración de los segmentos PQ/R, QT y QRS.

A retrospective study was conducted to identify the occurrence and types of ocular disorders in 57 Amazon parrots admitted to the Ophthalmology Service, Veterinary Teaching Hospital, School of Veterinary Medicine, University of São Paulo, Brazil from 1997 to 2006. The most frequent observed disorder was cataracts, present in 24 of the 114 examined eyes (57 parrots). Uveitis, ulcerative keratitis and keratoconjunctivitis were frequently diagnosed as well. The cornea was the most affected ocular structure, with 28 reported disorders. Uveal disorders also were commonly observed. Conjunctiva and eyelid disorders were diagnosed in lower frequency. Results suggest that cataracts are common and that cornea, lens and uvea are the most affected ocular structures in Amazon parrots.(AU)
Realizou-se estudo retrospectivo para identificar a ocorrência e os tipos de alterações oculares observadas em 57 papagaios atendidos no Serviço de Oftalmologia do Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo (USP), de 1997-2006. Catarata em diferentes estágios de evolução foi a alteração ocular mais frequentemente diagnosticada, sendo observada em 24 dos 114 olhos examinados. Uveíte, ceratite ulcerativa e ceratoconjuntivite foram também diagnosticadas. A córnea foi a estrutura ocular mais acometida (28 registros). Alterações uveais foram frequentemente observadas. Alterações das pálpebras e conjuntiva foram observadas em menor freqüência. Concluí-se que catarata foi a alteração mais frequentemente observada e que a córnea, lente e úvea são as estruturas oculares mais susceptíveis a alterações em papagaios.(AU)
