(p.ex. description des symptômes tels que la fréquence et la gravité
On 18 Jun 2013 a 7 year old, 18.6 pound female, mixed breed canine in good condition was seen by the veterinarian for a mass removal on the mammary gland. During the mass removal a routine spay was performed. The mass was a benign mammary adenoma. On 07-Jul-2013,the dog was administered 1 tube of K9 Advantix II Medium Dog (Imidacloprid Permethrin Pyriproxyfen) once topically by the owner. Thirty minutes after product application the dog developed application site pruritus and agitation. On 09 Jul 2013 the dog was being bathed. During the bath she developed pale mucous membranes and collapsed. The dog was taken to the emergency clinic and was pronounced dead on arrival. Attempts to resuscitate were not successful. The dog has been sent to Purdue University for necropsy. A preliminary necropsy report was recieved on 12 Jul 2013. Gross examination revealed the following findings Lungs Pulmonary congestion and edema Heart Cariomegaly, left atrioventricular valve endocardiosis, focal epicardial and myocardial pallor Abdominal cavity Mild serosanguineous effesion Liver hepatomegtaly Abdominal wall Multifocal subcuataneous and intramuscular hemorrhage. A definitive cause of the reported clinical signs and death in this dog could not be determined on gross examination. Histopathology, bacteriology and virology are currently pending. On 15 Jul 2013 the first results from the bacteriology were positive for E. coli, Clostridium perfringens and Clostridium bifermentans in the intestines. Virus isolation is currently pending from the intestines, lungs and tongue. Follow-up on 26 Jul 2013: 26 Jul 2013 The results of the necropsy revealed chronic cardiomyopathy and left atrioventricular endocardititis. Comments on Diagnosis Gross and histologic findings are consistent with chronic cardiomyopathy with cardiac enlargement, mycordial fibrosis and necrosis. Cardiac disease is a potential cause of sudden death in canines. The definitive cause of the myocardial changes is unknown; however, the chronic nature of the histiological changes indicates long standing myocardial disease that was not caused by the reported recent antiparasitic treatment. The histologic lesions in the kidney also represent chronic changes that may be related to chronic cardiovascular disease. No more information is expected. Case is closed. NOTE the dog had presented application site pruritus and agitation after a previous application of Advantix.
Mort
Reported application site pruritus and agitation may reflect paraesthesia caused by permethrin, shortly after application of product. These early signs and their time to onset are consistent. However, death not expected in dog after product application, as inconsistent with pharmaco-toxicological product profile. No signs of allergy/anaphylactic reaction reported. As time to onset to death was 2 days, allergic/anaphylactic reaction can be excluded. Other etiologies more probable, in particular as dog had recent history of neoplasm and surgery. Necropsy revealed chronic myocardial disorder and renal disorder, deemed to be responsible for dogs death. Considering all aspects, product connection is unlikely.
