Concurrent Transitional Meningioma and Ceruminous Gland Adenocarcinoma in a Scottish Wildcat Hybrid (Felis silvestris).

The Scottish wildcat (Felis silvestris) is an iconic and endangered subpopulation of the European wildcat (F. silvestris silvestris). There is much research devoted to the ecology, genetics and conservation of this animal, but little published information on pathology and disease. The investigation and reporting of such information is vital to furthering understanding of the effects of hybridization, a factor that is crucial if we are to secure a future for the Scottish wildcat. This report describes the clinical presentation, gross post-mortem and histological findings in an elderly Scottish wildcat hybrid with concurrent transitional meningioma and ceruminous gland adenocarcinoma.

Endogenous lipid pneumonia in an African grey parrot (Psittacus erithacus erithacus).

Lipid pneumonia is an unusual, non-infectious, inflammatory lung disease characterized by patchy pneumonic consolidation secondary to accumulation of lipid in macrophages. It can be classified as exogenous or endogenous, depending on whether it is associated with the aspiration of foreign material. Endogenous lipid pneumonia (EnLP) has been reported in many mammal species. In pet birds, EnLP is an incidental and uncommon lesion of unknown pathogenesis. A 35-year-old African grey parrot (Psittacus erithacus erithacus) was presented for depression lasting several months, with marked worsening over the 2 days prior to presentation. The animal died shortly after admission. Necropsy examination showed that the lungs were firm with diffuse grey discolouration. Microscopically, there was EnLP, anthracosis, severe atherosclerosis and hepatic amyloidosis. Although the pathogenesis of EnLP in birds is not clear, it has been associated with concurrent atherosclerosis, hepatic diseases and other lesions of the respiratory tract. This is the first description of EnLP in a bird associated with severe respiratory distress.

Formas de presentación de la enfermedad diverticular en los pacientes del servicio de gastroenterología del Sahum

El propósito del estudio fue identificar las formas de presentación más frecuentes con que cursan los pacientes con enfermedad diverticular que son atendidos en el SAHUM, en el período 2003 - 2006. Se realizó una revisión de historias clínicas de pacientes con enfermedad diverticular ambulatorios u hospitalizados, que fueron diagnosticados a través de colonoscopia o métodos de imagenes, cuyos datos fueron reportados en una ficha derecolección diseñada en función de las variables del estudio. Conclusiones: la forma mas frecuente de presentación de la enfermedad diverticular fue la simple con cerca de un 50 %, además es importante resaltar que la hemorragia digestiva inferior secundaria a esta enfermedad presento una incidencia elevada comparada con la reportada a nivel mundial.

The purpose of the study was to identify the forms of presentation more frequently found in patients with diverticular disease treated at the SAHUM, in the period 2003-2006. We made a revision of clinical histories of patients with diverticular disease ambulatory or hospitalized, who were diagnosed through colonoscopy or other imaging methods, whose data were reported in a card of data collection in function of the variables of the study. Conclusions: the presentation form most frequent of the diverticular disease was the simple one with close to 50%, moreover is important to stand out that lower digestive haemorrhage secondary to this disease presented a high incidence compared with the one reported at world level.

Clinical aspects of systemic granulomatous inflammatory syndrome in ferrets (Mustela putorius furo).

Nine ferrets (Mustela putorius furo) were diagnosed with systemic granulomatous inflammatory syndrome between 2005 and 2006. Common signs included diarrhoea, lethargy, weight loss, and weakness in the hindlimbs. Pathological findings consisted of mesenteric lymphadenopathy, splenomegaly, hypergammaglobulinaemia and non-regenerative anaemia. The condition was progressive and fatal in all the cases.

Identification of group 1 coronavirus antigen in multisystemic granulomatous lesions in ferrets (Mustela putorius furo).

Tissues from nine ferrets with granulomatous lesions similar to those seen in feline infectious peritonitis were examined histopathologically and immunohistochemically. Four main types of lesions were observed: diffuse granulomatous inflammation on serosal surfaces; granulomas with areas of necrosis; granulomas without necrosis; and granulomas with neutrophils. Other less commonly seen lesions were granulomatous necrotizing vasculitis and endogenous lipid pneumonia. FCV3-70 monoclonal antibody produced immunolabelling of group 1 coronavirus antigen in tissue samples from eight animals, the antigen being present in the cytoplasm of macrophages in the different types of granulomatous lesions.
