The 2 equations used to calculate SIG yielded significantly different results and cannot be used interchangeably. The authors believe SIG(2) to be a more accurate reflection of acid-base status in healthy dogs, and recommend that this calculation be used for future studies.
Case summaryA 1-year-old, female spayed domestic shorthair cat with a 6 week history of upper respiratory signs and a progressive reluctance to move, which culminated in a right-sided hemiparesis, was found to have a sewing needle foreign body lodged in the brainstem. Surgical extraction of the needle was successful and the cat’s neurological deficits resolved over the days to weeks following its removal.Relevance and novel informationThis case report describes, to our knowledge, the first reported incidence and management of an ingested sewing needle migrating into the central nervous system of a cat.
Because urinary bladder rupture can be life threatening, a simple, safe technique for evaluating patients is desirable. Current diagnostic protocols involve radiographic imaging, but ultrasound-based contrast techniques have not been methodically evaluated in veterinary patients with urologic trauma. Ultrasound contrast cystography (contrast cystosonography) involves infusion of microbubbled saline solution through a urinary catheter. It was performed in an in vitro model and in 2 dogs with naturally occurring urinary bladder rupture. A positive result consisted of visualizing microbubbles sonographically in fluid surrounding the bladder immediately after infusion of contrast into the urinary catheter. A positive result was obtained both in the in vitro model and in the 2 dogs, with radiographic and surgical confirmation of naturally occurring intraperitoneal urinary bladder rupture in the dogs. Based on the results of this study, ultrasound contrast cystography appears to be more sensitive than two-dimensional (2D) abdominal sonography for detecting naturally occurring urinary bladder rupture in dogs.
This is the first reported case of PH and hemoperitoneum in a Bartonella species serology positive dog wherein treatment with azithromycin resulted in serology negative status. There have been no subsequent episodes of hemoperitoneum in the 12 months since treatment.
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.
