We are liking this very current article:. Comparison of clinical findings between dogs with suspected anaphylaxis and dogs with confirmed sepsis. Walters, Andrea M.; O’Brien, Mauria A.; Selmic, Laura E.; McMichael, Maureen A. Journal of the American Veterinary Medical Association.9/15/2017, Vol. 251 Issue 6, p681-688. This is an interesting issue… I strongly suspect that I have missed diagnoses of anaphylaxis in the past … Continue reading
This case is an illustration of why some deep pyoderma cases in short-haired breeds can be difficult to fix. Obviously it’s sensible to rule out factors such as hypothyroidism, HAC, demodicosis, immunosuppressive drugs etc. This particular patient had been through that process quite thoroughly. After months of struggling, we examined the lesions under … Continue reading
Three forms of Demodex are carried by dogs and are sometimes associated with dermatitis D. canis and D. cornei have been shown to be morphological variants of the same species. Which makes sense since they can often be found in the same skin scrapes from dogs affected with conventional demodicosis. Vet Dermatol. 2012 Dec;23(6):509-e101. doi: … Continue reading
Amongst the various potential adverse effects of cyclosporine in dogs is a gingival hyperplasia. It’s not dramatic in this patient: they can be much worse. The same phenomenon is seen in people. In human medicine it can be managed with azithromycin in capsule or toothpaste formulation. In dogs this approach has proved less successful: Vet … Continue reading
This is just a slightly unusual shunt conformation in a six-month old kitten. As is common, the anomalous vessel originates from the base of the splenic vein and courses cranially and dorsally. The slightly unusual thing is that the confluence with the cava is intra-hepatic. With colour Doppler (clip starts with cava (above) … Continue reading
One of the cardinal rules of serious small animal sonography is ‘don’t forget to scan the ovaries, uterus and testicles’. At least in the UK it’s easy to forget that they’ve not always been removed!. A couple of recent examples: Firstly a young unilaterally-cryptorchid dog presented with acute abdominal pain. Impressively, the first opinion practitioner … Continue reading
AHDS (or HGE as it is probably more widely known) has long remained an enigmatic condition. Despite being common and serious, a definitive cause remained elusive. Cicrumstantial evidence supported the involvement of Clostridia but we lacked an explanation as to why only a few dogs develop signs when Clostridia are ubiquitous in gut flora… ….until … Continue reading
Neoplastic fever is an important differential for pyrexia. However, it’s easy to overlook the possibility and it’s also a phenomenon about which we know relatively little. An excellent summary from human medicine can be found here: http://www.clinicalcorrelations.org/?p=7966 I suspect that, as in people, hepatic masses (especially metastases) or lymphoma are the commonest culprits in dogs. … Continue reading
I’m interested in lung ultrasound. I feel it has a lot to offer, it’s quick and easy. For a while I’ve been waiting for a convincing case of pulmonary thromboembolism (PTE) to come along. It seems very likely that such cases exist amongst our workload but, since we don’t do a lot of CT angiography, … Continue reading
*Advanced warning -gory surgical photo involved here* This Great Dane presented with acute, non-tympanic abdominal distention and malaise. On sonography the spleen exhibits the classic ‘starry sky’ parenchymal pattern which is typical although not specific for torsion: There is no detectable flow in the splenic vessels with Doppler. At the point where the splenic veins … Continue reading
