components in human neutrophils, the two main antigenic targets being proteinase-3 (PR3) and myeloperoxidase (MPO). Clinical studies done at SA Pathology have found the combination of an ANCA screen and confirmation tests yield the best diagnostic information.

Osteoporosis is a major public health issue. Diagnosis relies on a bone mineral density (BMD) measurement, using dual energy X ray absorptiometry, and is defined as a bone density more than 2.5 standard deviations below the young normal (peak bone) values at the lumbar spine or the hip. Bone turnover markers (BTM) can be used as a complement to BMD in monitoring treatment response as well as fracture prediction in patients with osteoporosis.

Dr DevikA ThomAs
This interesting case highlights the value of clinical history when interpreting test results, particularly those like liver enzymes with significant non-specificity. It reminds us that context is crucial to unravelling the complex web of influences that produce any set of test results. For more on the liver function tests refer to IMVS Newsletter 57.

Wenn die Mieze hustet Ein Überblick über feline Atemwegserkrankungen Husten bei einer Katze sollte man nicht auf die leichte Schulter nehmen. Katzen erkälten sich nicht so leicht wie wir Menschen, Husten gehört bei ihnen nicht zum „Alltäglichen". Daher sollte eine Katze, die wiederholt hustet (ohne dabei etwas hervorzuwürgen, z. B. Haarballen) dem Tierarzt vorgestellt werden.Erste Asthma-Anzeichen zeigen sich oft im Alter von 1 – 3 Jahren, können aber auch früher oder später auftreten. Bei manchen Katzen tritt parallel Niesen und / oder Augenausfluss auf.Wenn eine Katze schwere Atemnot hat (mit geöffnetem Maul und sichtlicher Anstrengung atmet, dabei die Ellbogen evtl. etwas nach aussen dreht), muss sie unverzüglich in tierärztliche Behandlung – dieser Zustand ist lebensbedrohlich! Auch wenn es mitten in der Nacht geschehen sollte – warten Sie lieber nicht bis zum Morgen, sondern rufen Sie den tierärztlichen Notdienst oder bringen Sie Ihre Katze ins nächste Tierspital.
