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.

Outbreak of canine distemper in domestic ferrets (Mustela putorius furo).

In 2006 an outbreak of canine distemper affected 14 young domestic ferrets in Barcelona, Spain. Their clinical signs included a reduced appetite, lethargy, dyspnoea, coughing, sneezing, mucopurulent ocular and nasal discharges, facial and perineal dermatitis, diarrhoea, splenomegaly and fever. Late in the course of the disease, general desquamation and pruritus, and hyperkeratotic/crusting dermatitis of the lips, eyes, nose, footpads, and perineal area were observed. None of the ferrets developed neurological signs. Non-regenerative anaemia and high serum concentrations of alpha- and beta-globulins were the most common laboratory findings. Most of the animals died or were euthanased because of respiratory complications. Postmortem there were no signs of lung collapse. Distemper was diagnosed by direct immunofluorescence of conjunctival swabs or pcr of several organs, and histology revealed the characteristic eosinophilic intracytoplasmic and intranuclear inclusion bodies of canine distemper virus in several organs. The minimum incubation periods calculated for six of the ferrets were 11 to 56 days, and in 13 of the ferrets the signs of disease lasted 14 to 34 days. Inclusion bodies compatible with infection by herpesvirus were found in the lungs of one of the ferrets.

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.

Effects of acepromazine on capture stress in roe deer (Capreolus capreolus).

The aim of this study was to evaluate effect of a short-acting neuroleptic (acepromazine) on capture stress response in roe deer (Capreolus capreolus). Sixteen roe deer were captured by drive-nets in the winters of 1998, 1999, and 2001. Roe deer were divided into two groups: animals in the treatment group received an intramuscular injection of acepromazine (0.093 mg/kg +/- 0.003 SEM; n = 8) while animals in the control group (n = 8) did not receive tranquilizer. Heart rate and body temperature, as well as hematologic and biochemical indicators of stress, were used to evaluate effect of the neuroleptic over 3 hr. Heart rate decreased over time after capture in both groups (P < 0.05), but stabilized sooner in the treated roe deer (75 min after capture) than in the controls (105 min after capture). Body temperature decreased over 45 min and then stabilized in both groups (P < 0.05). Comparisons of blood parameters revealed significantly lower red blood cell count (RBC), lymphocyte count, hemoglobin concentration, packed cell volume (PCV), and serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK), and lactate dehydrogenase (LDH) activities in tranquilized animals compared with controls (at least P < 0.05). A reduction in PCV, lymphocyte count, and serum cortisol concentrations (at least P < 0.05) and an increase in serum creatinine levels (P < 0.05) were recorded over time in control animals, while a reduction in RBC and hemoglobin concentration (at least P < 0.05) and an increase in serum urea concentrations (P < 0.05) over time were observed in the treated group. Finally, a decrease in serum lactate and potassium levels and an increase in CK, AST, ALT, and LDH activities were recorded over time in both groups. Results obtained showed the suitability of using acepromazine in capture operations in order to reduce stress response and prevent its adverse effects in roe deer. The beneficial effect was not only due to the sedative effect of acepromazine, but also to peripheral vasodilatation.
