Article: [Ultrasonographic findings in a cow with extraskeletal chondroblastic osteosarcoma of the neck region].
[show abstract] [hide abstract]
ABSTRACT: This case report describes the clinical, ultrasonographic and pathological findings in a five-year-old Swiss Braunvieh cow with extraskeletal chondroblastic osteosarcoma of the neck region. The cow was referred because of a firm, non-painful swelling, approximately 25 cm in diameter, which was situated mainly on the lower left side of the neck but extended to the right. Ultrasonographic examination of the mass revealed a chambered structure containing echoic material that was separated by hyperechoic septa. Chondroblastic osteosarcoma was diagnosed based on histological evaluation of a biopsy sample, and the diagnosis was confirmed by postmortem examination.SAT Schweizer Archiv für Tierheilkunde 08/2010; 152(8):379-83. · 0.60 Impact Factor -
Article: Clinical findings in 28 cattle with traumatic pericarditis.
[show abstract] [hide abstract]
ABSTRACT: Traumatic pericarditis was confirmed postmortem in 28 cattle that had shown signs of a heart rate of more than 100 bpm, distended jugular veins and muffled heart sounds or abnormal pericardial sounds. The heart rate was higher than normal in 24 of them, and in 18 of these it ranged from 100 to 130 bpm. Twenty of the cattle had muffled heart sounds and 10 had pericardial sounds, such as splashing, rubbing or squeaking sounds. Both jugular veins were distended in 24 of the cattle, and 15 had oedema of the throat region, brisket and ventral abdomen. The most important laboratory findings were a reduced clotting time in the glutaraldehyde test in 26 animals, leucocytosis in 22 and a higher than normal concentration of fibrinogen in 19. There was an increase in the activity of gamma-glutamyl transferase in 20, and of aspartate aminotransferase in 15, and in the concentration of bilirubin in 11 of the cattle, indicative of hepatic congestion. A definitive diagnosis of traumatic pericarditis was made on the basis of the clinical findings in 15 of the 28 animals, all of which had typical signs of the disease. In another eight animals, traumatic pericarditis was suspected, although one of the characteristic signs was absent. A tentative but incorrect diagnosis of valvular endocarditis was made in three animals, and a similarly incorrect diagnosis of traumatic reticuloperitonitis was made in the other two.The Veterinary record 11/2007; 161(16):558-63. · 1.25 Impact Factor -
Article: Reverse transcription real-time PCR assays for detection and quantification of Borna disease virus in diseased hosts.
[show abstract] [hide abstract]
ABSTRACT: Borna disease is a severe, immunopathological disorder of the central nervous system caused by the infection with the Borna disease virus (BDV). The detection of BDV in diseased animals, mainly sheep and horses, is achieved by histological, immunohistochemical and serological approaches and/or PCR-based technologies. In the present study, reverse transcription, real-time PCR assays were established for the detection of BDV in the brain tissue from sheep and horses, using loci for the p40 (nucleoprotein) and the p24 (phosphoprotein) genes. The PCRs were equally specific and sensitive, detecting 10 target molecules per reaction and one BDV-infected cell among 10(6) non-infected cells. In tissues from BDV-diseased sheep and horses, the p24 target was detected at higher abundance than for p40. Therefore, the p24 test is suggested to be of higher value in the diagnostic laboratory. However, both assays should be useful for addressing questions in pathogenesis and for detecting BDV reservoirs in endemic areas.Molecular and Cellular Probes 03/2007; 21(1):47-55. · 2.08 Impact Factor
