Rabbits Flashcards
Rectal prolapse in two rabbits with rectal neoplasia
Two adult pet rabbits presenting for prolapse, still eating/drinking. In both cases the rectal mass was palpable (not sure if by rectal (yikes) or abdominal palpation)? CBC/Chem, AUS & rads wnl both rabbits. Both went to surgery. Inflammatory polyp and a leiomyosarcoma. Both have done great for 2-3 years post op.
Cutaneous squamous cell carcinomas in domestic rabbits (Oryctolagus cuniculi): 39 cases (1998-2019)
Wide range in cases; predilection for ears and feet and possibly lighter-colored rabbits. One case had a papillomavirus involved, other 16 that were tested did not. Aggressive surgical margins provided best outcomes.
Outcomes and survival times of client-owned rabbits diagnosed with thymoma and treated with either prednisolone or radiotherapy, or left untreated
Highly suspected or confirmed thymoma (hmm). intensity-modulated radiotherapy (IMRT) (n = 5) and prednisolone therapy alone (n = 18). A cohort of rabbits that received no treatment (n = 10) was also evaluated and used for comparison. IMRT did not prolong survival above those with no treatment, but did have better QOL/less clinical signs for most of that period. Prednisolone extended survival times!
Analysis of the nutrient composition of selected commercial pet rabbit feeds with respect to nutritional guidelines
No names named but basically every food did not meet criteria for fiber or actually match their labels. Yikes.
Patellar luxation in rabbits (Oryctolagus cuniculus): 6 cases (2017-2020)
All 6 presented for acute unilateral hindlimb lameness. 2 with grade 2 MPL responded to rest and medical management. 2 failed medical mgmt, 1 went to surgery; 2 went straight to surgery. of the 3 that had surgery, all had good outcomes.
Diagnosis, treatment, and characterization with advanced diagnostic imaging of an oral ectopic elodontoma in a pet rabbit (Oryctolagus cuniculus)
dwarf mix rabbit. basically, elodontoma arose from the buccal mucosa. Had an associated abscess. Mass and abscess removed, molar trim done, continues to need molar trims but 16 months later doing well.
The effects of single-dose administration of two topical antiglaucoma medications, 0.005% latanoprost and 0.125% demecarium bromide, on intraocular pressure and iridocorneal angle parameters in nonglaucomatous companion rabbits
each applied to one eye of 20 mixed breed rabbits. Latanoprost did not affect IOP, but increased the gonioscopy score (which I guess is good). Demecarium decreased the gonioscopy score and increased IOP. Ok to try latanoprost, do not use demecarium.
Hepatic coccidiosis in two pet rabbits
Yikes. Two young emaciated rabbits presented with diarrhea. Microscopic fecal examination identified ellipsoidal oocysts. Both rabbits died. on necropsy both livers were basically replaced by damaged hepatocytes and dilated bile ducts, with intrahepatic coccidia etc. Ultrasound changes were present but not that marked.
Labwork:
Increased: Eosinophils, platelets, ALP, ALT, GGT, globulins
Decreased: albumin, amylase, blood urea nitrogen, and creatinine
basically they died of liver failure. Yeesh
Sodium intoxication in a domestic rabbit
acute onset of seizure-like activity, ataxia, vestibular-associated rolling, and obtunded mentation. Had been nibbling a Himalayan salt rock. Recovered after 48h supportive care.
Diagnosis and treatment of glaucoma in client-owned rabbits (Oryctolagus cuniculus): 16 eyes from 11 rabbits (2008–2019)
Median IOP at diagnosis was 39 mmHg (26-55 mmHg) with various clinical signs at presentation including vision loss (11 rabbits, 16 eyes), buphthalmia (8 rabbits, 11 eyes), corneal edema (4 rabbits, 5 eyes), and optic nerve head cupping (5 rabbits, 6 eyes). Other ocular examination findings included cataracts (5 rabbits, 8 eyes) and uveitis (4 rabbits, 8 eyes). Two rabbits were seropositive for Encephalitozoon cuniculi. All eyes were initially treated with topical medications, with 10 eyes from 7 rabbits refractory to initial medical management. Two rabbits (3 eyes) showed progressive reduction in IOPs with long-term continuing topical therapy. Two rabbits (2 eyes) underwent unilateral enucleation and 3 rabbits (5 eyes) received intravitreal gentamicin injections.
Renal embryonal nephroma exhibiting malignant features in a Dutch rabbit (Oryctolagus cuniculus)
basically 3yo rabbit had a tumor, they took out the kidney, evidence of abdominal mets in sx/histopath, but a year out from sx no palpable regrowth or clinical signs.
Diatrizoate contrast agent study for luminal patency and visualization of the gastrointestinal tract in healthy rabbits (Oryctolagus cuniculus) and its influence on selected blood parameters and fecal quality
2, 7 or 10 ml/kg of iodine/diatrizoate combo. all were effective for various times not in abstract. all 3 caused changes in urea and creatinine - still within reference ranges but statistically significant. Dry matter in feces decreased at the higher dosages and some of the 10 ml/kg group got diarrhea (self limiting).
Characterization of cells collected from nasolacrimal duct flush samples in healthy rabbits (Oryctolagus cuniculus)
Generally low cellularity (500 cells/L), heterophils highest percentage.
Contrast echocardiography for detecting bidirectional shunting in a rabbit with an atrial septal defect
Cardiomegaly found incidentally in 3 yo rabbit. Echo + agitated saline contrast echocardiography can be easily performed and provides an accurate assessment of hemodynamic status in rabbit. Therefore, it should be widely considered for the diagnosis of rare congenital cardiac defects in rabbits. survived another 2 years after dx, died of CHF.
Tracheal resection and anastomosis for treatment of tracheal collapse in a rabbit
A 7-year-old rabbit with concurrent upper respiratory disease was diagnosed with tracheal collapse using diagnostic imaging and tracheoscopy. Tracheal resection and anastomosis was performed to remove the affected area and produced resolution of clinical signs for approximately 6 months. The patient’s signs eventually returned due to development of granulation tissue at the anastomosis site.
Intra-abdominal torsion of a neoplastic testicle in a rabbit (Oryctolagus cuniculus) with cryptorchidism
Acute anorexia. Transabdominal ultrasonography showed a structure consistent with an enlarged testis, with decreased echogenicity, and absent blood flow upon color Doppler ultrasonography. Sertoli cell tumor on histopath. arrested in surgery, revived, proceeded with neuter.
Naturally occurring tetanus in a rabbit (Oryctolagus cuniculus) associated with Psoroptes cuniculi otitis
Cytology of the aural crusts confirmed the presence of Psoroptes cuniculi and Gram stain of the purulent material confirmed concurrent mixed bacterial otitis with a large number of nonsporulating Gram positive rods. euthanized after developing tetanus. various tests confirmed Clostridium tetani with nerve toxin. Holy shit!
Preliminary evaluation of an immunoturbidimetric assay and lateral flow device for the measurement of serum amyloid A in rabbits
Reference laboratory testing for APPs allows for accurate measurement of SAA and CRP; the point of care lateral flow device (LFD) offers a new option for point of care testing. Additional studies may show that APPs can have value in the diagnosis and prognosis of diseases in rabbits. Whee.
Presumptive nonthyroidal illness syndrome in pet rabbits (Oryctolagus cuniculus)
euthyroid sick - origin of the fractures and ileus thing. included both t4 & free t4 (unspecified type) and both were affected by fx/ileus.
Comparison of enzyme-linked immunosorbent assay and immunofluorescence test for determination of anti-Encephalitozoon cuniculi antibodies in sera from rabbits with different clinical and histopathological presentations
ELISA vs IFA (two different labs). good agreement but not quite equivalent. specificity 100%, sensitivity 50-80%. IgG and IgM are different from each other. Whee.
