Dioctophymosis is caused by Dioctophyme renale, a nematode that usually affects the right kidney of carnivores. The aim of this study was to report on a case of a dog with progressive weight loss and swollen abdomen that was diagnosed as presenting dioctophymosis. The patient underwent surgical treatment through which 34 nematodes were found, of which 18 were female and 16 were male, with a maximum length of 74 centimeters. The parasites were free in the abdominal cavity and inside the right kidney, and had caused peritonitis, free fluid, severe adherences between the abdominal organs and renal perforation. Parasitic diseases with a high number of specimens of this species are uncommon in dogs. The disease progresses with an inflammatory reaction and consequent formation of adherences and granulomatous tissue. This surrounds the eggs that were eliminated in the abdominal cavity by the free parasites. This disease occurs frequently in the city of Pelotas, Rio Grande do Sul, Brazil, where the patient of this report was living. To the best of authors’ knowledge, this is the case with the largest number of specimens of D. renale removed from a single dog in vivo.
This study aimed to evaluate the effectiveness of acepromazine as an adjuvant to ketamine, midazolam and methadone in the chemical restraint and anesthesia of cats undergoing ovariohysterectomy. We allocated 14 cats in two groups: group ketamine (GK), premedicated with ketamine 8 mg/kg, midazolam 0.3 mg/kg and methadone 0.3 mg/kg and group acepromazine (GAK), premedicated with acepromazine 0.05 mg/kg in addition to the above-mentioned drugs. At baseline (T0) and every 5 mins up to 20 mins (T5, T10, T15 and T20) after premedication, the sedation score was evaluated at 0 to 24 points. The sedation score was significantly higher at T5, T10, T15 and T20 in both groups. There were no significant differences in extubation times (3.7 ± 1.3 mins in GK; 5.2 ± 2.6 mins in GAK) and the time to reach a score equal to 0 on the sedation scale (88 ± 63.9 mins in GK; 133 ± 39.7 mins in GAK); however, the time of anesthetic release was significantly higher in the GAK than in GK (19.7 ± 6.5 mins vs 11 ± 5.9 mins) (P = 0.023). Sedation was adequate in both groups. The results indicated that the administration of acepromazine did not contribute to sedation in the protocol and could delay the anesthetic release.
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.
