Sixty cases of canine sialocoele were reviewed from the records of the Sydney University Veterinary Teaching Hospital. Poodles, dachshunds and Australian silky terriers were significantly over represented in the survey when compared to the hospital sample population (P&0.01). No other statistically significant breed, sex, or age trends were noted. Neoplasia was associated with sialocoele formation in three cases. The sialocoele location was cervical (42), sublingual (four), pharyngeal (four), not recorded (one) or in more than one site (nine). Thirty‐five of 39 surgically treated cases were managed by extirpation of the mandibular and sublingual salivary glands together with drainage. Few complications were recorded. Forty‐two per cent of the cases had received previous veterinary treatment in the form of drainage alone. Drainage of saliva from sialocoeles without removal of the offending salivary glands is inappropriate.
The serum concentrations of serum amyloid A, haptoglobin and fibrinogen were measured in a group of horses before and at intervals after elective and non-elective surgery, and in a control group of normal horses. There was a significant, rapid and repeatable increase in the concentration of serum amyloid A in response to both elective and non-elective surgery. In the control horses its serum concentration was within the normal range, from 0 to 0.2 microg/ml. Twenty-four hours after elective surgery its mean peak concentration was 16.4 microg/ml, and after non-elective surgery it was 27.3 microg/ml. In contrast, the serum concentrations of haptoglobin and fibrinogen increased more slowly after surgery and had not decreased by 72 hours after surgery.
The development of severe secondary laryngeal changes in dogs aged six months or less supports the suggestion that immature brachycephalic dogs should undergo assessment and, if indicated, surgery as soon as any clinical signs of BAS are apparent.
Subcapsular perirenal pseudocysts are formed in cats by accumulation of transudate between the capsule and parenchyma of the kidney as a result of underlying parenchymal disease. Pseudocyst formation can occur at variable stages of renal dysfunction. Resection of the pseudocyst wall is usually effective in eliminating signs but does not stop progression of renal disease. The prognosis for cats with pseudocyst formation is related to the degree of renal dysfunction at time of diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
