Willi, B; Kook, P; Quante, S; Boretti, F; Sieber-Ruckstuhl, N S; Grest, P; Scherrer, O; Riond, B; Hofmann-Lehmann, R; Nussberger, J; Reusch, C (2012). Primärer Hyperaldosteronismus bei Katzen. Schweizer Archiv für Tierheilkunde, 154(12):529-537.

Abstract

Primary hyperaldosteronism is a clinical syndrome characterized by an elevated aldosterone secretion by the adrenals. The present case series describes 7 cats with primary hyperaldosteronism, which were presented between 2002 and 2011. Common clinical symptoms were weakness, anorexia, cervical ventroflexion and blindness. All cats showed hypokalemia. In 6 cats, blood pressure was determined: 5 cats showed hypertension, of which 4 animals exhibited retinal detachment and blindness. In the ultrasonographic examination, unilateral adrenomegaly was present in 6 cats whereas one animal showed normal adrenals. In 4 cats, the serum aldosterone concentration was above the reference range. Five cats underwent unilateral adrenalectomy, which was accomplished uneventfully and returned the electrolytes back to normal. Histopathological examination of the adrenals revealed 2 carcinomas and 4 adenomas; one cat with ultrasonographic normal adrenals exhibited bilateral nodular hyperplasia.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
