A 9-year-old Arabian stallion with a 3-year history of infertility was evaluated for breeding soundness. Both testes were small. Ultrasonography revealed a small amount of free fluid between the ...tunics of both testes. Results of cytologic examination of the fluid were unremarkable. On semen examination, progressive motility was 10%, and total number of spermatozoa in the ejaculate was 6.6 x 10(9), of which 92% were abnormal. Predominant abnormalities were head defects (75%): 57% of the heads had single or multiple vacuoles, and 60% also had midpiece swelling or bending.
Aortic stenosis (AS) has become an increasingly prevalent condition in ageing Western populations. Symptomatic AS is associated with significant morbidity, high hospitalisation rates and reduction in ...quality of life and life-expectancy. A large number of patients with severe AS are not currently receiving proper treatment, with subsequent increased mortality. While surgical aortic valve replacement continues to be an effective treatment for these patients, transcatheter aortic valve implantation is a new alternative for those at high risk from surgery. Overall, valve replacement and implantation procedures have a significant impact on prognosis and quality of life in AS patients. Referring a patient to a centre that has a multidisciplinary heart team will ensure that all treatment options are fully explored and the best clinical outcomes are reached.

Two stallions had unilateral bacterial epididymitis attributable to S zooepidemicus infection. Diagnosis was based on bacterial isolation, WBC in the semen, higher than normal blood fibrinogen ...concentration, and leukocytosis with regenerative left shift. One horse had high seminal pH. Ultrasonography of the involved epididymides revealed changes consistent with the appearance of abnormal accumulation of exudate in the tail of the epididymis. Treatment included unilateral orchiectomy and antibiotic administration. In stallion 1, the infection persisted despite treatment. Treatment result was not available for stallion 2.
The effect of flunixin meglumine on renal function was studied in 6 healthy horses by use of nonimaging nuclear medicine techniques. Effective renal plasma flow (ERPF) and effective renal blood flow ...(ERBF) were determined by plasma clearance of 131I-orthoiodohippuric acid before and after administration of flunixin meglumine. Mean ERPF and ERBF was 6.03 ml/min/kg and 10.7 ml/min/kg, respectively, before treatment and was 5.7 ml/min/kg and 9.7 ml/min/kg, respectively, after treatment. Although ERPF and ERBF decreased after flunixin meglumine administration, the difference was not statistically significant
Zusammenfassung
Expansiv wachsende Osteoblastome der Halswirbelsäule sind selten, können aber aufgrund ihrer Nähe zu neurovaskulären Strukturen zu schweren neurologischen Störungen führen. ...Insbesondere die A. vertebralis in ihrem transvertebralen Verlauf ist nicht selten von Tumorgewebe ummauert und bei angestrebter totaler Tumorresektion gefährdet. Neben dem konventionellen Röntgen und der Computer- und Magnetresonanztomographie gibt die Okklusionsangiographie mit paralleler transkranieller Dopplersonographie Hinweise über die Resektabilität hirnversorgender Gefäße. Der hier dargestellte Fall beschreibt das stufenweise diagnostische Vorgehen und die erfolgreiche vollständige Resektion eines Osteoblastoms des 5. Halswirbels mit massiver intraspinaler Raumforderung bei einem 11-jährigen Knaben unter Erhalt der langstreckig ummauerten A. vertebralis dextra.
