(eg. description of the frequency and severity of the symptoms

9/19/2011 1:43:32 PM: DVM states Advantage II was applied for the first time on 9/15/11 in the clinic at the time of an appointment for dysuria. The cysto was not submitted. The cat was discharged and became distressed on the car ride home and developed respiratory distress. The cat re-presented immediately upon arriving home and re-presented cyantoic, open mouth breathing, foaming, salivating and recumbent. The cat was intubated and was placed on O2, had a temperature of 103.6. The cat arrested within 10 minutes, and was re-vived with CPR, then arrested again within 3 minutes and the caller states they were unable to revive the cat a second time. The caller states a necropsy was performed and the DVM cannot tell what was post mortem change, but states she sees bloody fluid in the chest and abdomen and notes that her impression was hemorragic shock. No emesis was noted in any of the airways. Histopath was sent out and is pending. The DVM notes on discharge the temp was 101.7. Update 10.10.2011 Technical assessment: The complained batch was manufactured according to specifications. No deviations occurred. Update 17.10.2011: Post mortem radiographs of thorax and abdomen revealed air filled stomach. Owner declined necropsy. Doctors differential diagnosis is open: Anaphylactoid reaction, Cardiomyopathy related, vomit/aspiration or thrombosis. On 9/16/2011 owner allowed necropsy. The body was taken out of the freezer to thaw. On 9/18/2011 gross necropsy at the regular veterinary clinic: proximate cause of death appears to be acute pulmonary edema with subsequent body cavity effusion but cause of edema could not be conclusively determined: however significant numbers of eosinophils in alveolar fluid suggest an allergic/anaphylactic component. On 9/21/2011 histopathology report from an independent consultation service. Clinical history: Presented for straining to urinate: cystocentesis preformed, claws trimmed, dose of Advantage II applied: vomited during the ride home, following by severe respiratory distress, cyanosis and foaming at the mouth by the time it returned to hospital: arrested, CPR performed but rearrested and could not be revived: necropsy (body had been frozen and thawed) = good body condition, heart seemed small, bloody effusion in chest and abdomen, lungs appeared diffusely hemorrhagic, petechiae on omentum and bladder was full, mesenteric nodes slightly prominent. Diagnosis: A. Heart - Mild mutifocal acute or subacute myocardial necrosis B. Lung - Marked pulmonary congestion and edema with mild eosinophilic pneumonia, pulmonary artery smooth muscle hypertrophy. C. Kidney - Mild to moderate medullary fibrosis and tubular degeneration. Comments: This is a complex case. and the relative roles of the various lesions is difficult to determine. The proximate cause of death appears to be acute pulmonary edema and subsequent body cavity effusion. Significant numbers of eosinophils in the alveolar fluid suggest an allergic/anaphylactic component: however, typical lesions of underlying feline asthma were not appreciated. The etiology of feline pulmonary artery hypertrophy is still unclear: some but not all cases are attributed to previous parasite exposure or chronic hypertension. It is also unclear if this lesion is always associated with hemodynamic alterations that are of pathologic significance. The small heart size could be due to hypovolemia from the body cavity effusions: there is no obvious cardiomyopathy. Myocardial necrosis is very unusual finding in cats: it was not possible to determine if it was a result of tissue hypoxia due to pulmonary edema or primary cause of cardiac dysfunction leading to pulmonary edema. The latter seems less likely based on the small size and number of necrotic foci in the heart. No further information expected.

19. Provide supplemental information here

Reported signs inconsistent with pharmaco-toxicological product profile and experience. Post-mortem examination revealed myocardial necrosis and pulmonary edema but pathogenesis still unclear. The necropsy results indicate that other etiologies could be contributing facts in the clinical signs and death. based on available information a product relation was ruled out. No quality issues were noted upon product investigation.
