Over time, diabetes patients are at increased risk for microvascular and macrovascular complications leading to increased morbidity and mortality compared to metabolically healthy people. In addition, acute life-threatening metabolic derangements at first manifestation as well as during the course of the disease may occur, comprising diabetic ketoacidosis, hyperosmolar hyperglycaemic state and hypoglycaemia. Diabetes-related emergencies require fast diagnosis and early treatment initiation as well as close monitoring of vital signs and laboratory parameters. The present article gives an overview on the acute metabolic complications in diabetes, focussing on diagnostic work-up and treatment goals., Competing Interests: Erklärung zu finanziellen InteressenForschungsförderung erhalten: nein; Honorar/geldwerten Vorteil für Referententätigkeit erhalten: nein; Bezahlter Berater/interner Schulungsreferent/Gehaltsempfänger: nein; Patent/Geschäftsanteile/Aktien (Autor/Partner, Ehepartner, Kinder) an Firma (Sponsor der Veranstaltung): nein; Patent/Geschäftsanteile/Aktien (Autor/Partner, Ehepartner, Kinder) an Firma (Nicht-Sponsor der Veranstaltung): nein.Erklärung zu nichtfinanziellen InteressenDie Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Using B-mode ultrasonography, the frequency of carotid atherosclerosis was investigated prospectively in 50 patients on maintenance haemodialysis compared to healthy controls. The patients showed significantly more atheromatous plaques at the carotid bifurcation, as well in the internal and external carotid artery (chi-square-test, p less than 0.05). There was no statistical difference between normotensive patients on haemodialysis and the control group, but hypertensive patients showed statistically significant more plaques of the cervical vessels (chi-square-test, p less than 0.05). Therefore, atheromatous plaques in haemodialysis patients appear to be due to hypertension rather than to maintenance dialysis.

Concentrations of rumen fluid characteristics were compared between rumen fluid which was taken by standardized conditions via stomach tube and via rumen fistula respectively depending on time after feeding (2.5 or 9 hours ppr.). The results were as follows: Differences (%) of the characteristics of rumen fluid taken via stomach tube to that by rumen fistula: [table: see text] Other investigations showed that the admixture of saliva to rumen fluid resulted in a degradation of the concentrations especially of VFA. The pH was not appreciable changed. The consequences for veterinary practitioners are discussed.
