Endoscopic administration of Coca-Cola for medical management of a wedged intestinal trichobezoar in a cat.

A 16-year-old, neutered male domestic longhair feline with gastroduodenal and jejunal trichobezoars was treated with administration of Coca-Cola through endoscopic injection catheter. Examination with a Karl Storz endoscope identified a trichobezoar causing suspected partial or early complete obstruction of the jejunum; however, the length of the scope was inadequate to retrieve the trichobezoar. Consequently, 55 mL of Coca-Cola and 5 mL of iohexol were instilled into an injection catheter to disrupt the trichobezoar.

Serum Cobalamin and Folate Concentrations in Common Marmosets () with Chronic Lymphocytic Enteritis.

Serum cobalamin and folate concentrations can serve as surrogate markers of gastrointestinal disease in dogs and cats, where they can have diagnostic, therapeutic, and prognostic implications. Chronic disease of the gastrointestinal tract, particularly chronic lymphocytic enteritis (CLE), occurs frequently in captive common marmosets. The aims of this study were to validate a commercially available assay for measuring serum cobalamin and folate concentrations in common marmosets, to establish reference intervals for these analytes in healthy marmosets, and to measure serum concentrations in common marmosets with CLE.

Gastrointestinal pythiosis with concurrent presumptive gastrointestinal basidiobolomycosis in a Boxer dog.

A 2-year-old female spayed Boxer dog was presented for a 1-month history of progressive hemorrhagic diarrhea with tenesmus and weight loss despite trial courses of antibiotics and diet change. Abdominal ultrasound revealed severe, focal thickening, and loss of normal architecture of the colonic wall with abdominal lymphadenomegaly. Dry-mount fecal cytology, performed on several consecutive days, consistently revealed numerous, round, 16-20 μm structures with basophilic, granular content, and a thin cell wall.

Fecal Concentrations of N-methylhistamine in Common Marmosets ().

Chronic lymphocytic enteritis (CLE) is a frequent disease in common marmosets. However, no diagnostic test for early detection of CLE is available. Mast cells have an important role in gastrointestinal disease.

Development and analytic validation of a sandwich ELISA for the measurement of α-proteinase inhibitor concentrations in serum and feces of common marmosets (Callithrix jacchus).

OBJECTIVE To develop and validate a sandwich ELISA for the measurement of α-proteinase inhibitor (α-PI) concentrations in serum and fecal samples obtained from common marmosets (Callithrix jacchus). SAMPLE Leftover serum (n = 42) and fecal (23) samples submitted for diagnostic testing; paired serum and fecal samples obtained from 30 common marmosets at 2 research colonies. PROCEDURES A sandwich ELISA was developed and analytically validated by determining the lower limit of detection, linearity, accuracy, precision, and reproducibility.

Urine-Filled Large Prostatic Cystic Structure in Two Unrelated Male Miniature Dachshunds.

A 1 yr old intact male miniature dachshund presented for posturing to urinate without voiding and nocturia. Physical examination revealed congenital reproductive abnormalities and a fluid-filled structure caudal to the urinary bladder. The dog was diagnosed with a prostatic cyst and underwent an exploratory laparotomy with an attempt to remove the cyst.

Randomized placebo controlled clinical trial of an enteric coated micro-pelleted formulation of a pancreatic enzyme supplement in dogs with exocrine pancreatic insufficiency.

Background: Pancreatic enzyme supplements for the treatment of exocrine pancreatic insufficiency (EPI) in dogs can be uncoated or enteric coated. Enteric coated supplements might be advantageous.

Hypothesis/objectives: Enteric coated enzyme supplements are superior to uncoated supplements in dogs with clinical EPI.

Development and analytical validation of a radioimmunoassay for the quantification of alpha -proteinase inhibitor in serum and feces from the common marmoset (Callithrix jacchus).

Background: The objective of this study was to develop and analytically validate a radioimmunoassay (RIA) for the measurement of alpha -proteinase inhibitor (α -PI) concentrations in serum and feces from the common marmoset.

Methods: Serum samples (n = 30) and 3-day fecal samples (n = 30) were obtained from healthy marmosets. An RIA was established and validated by determination of sensitivity, working range, dilutional parallelism, spiking recovery, and intra- and interassay variability.

Evaluation of density gradient ultracentrifugation serum lipoprotein profiles in healthy dogs and dogs with exocrine pancreatic insufficiency.

Changes in proportions of lipoprotein classes have been described in disease states in humans. In veterinary medicine, hyperlipidemia can cause complications, such as cutaneous xanthomas, liver disease, cholelithiasis, pancreatitis, glomerular disease, lipemia retinalis, or peripheral neuropathy, but there are few reports regarding lipoproteins in diseased animals. For canine serum, we partially validated continuous lipoprotein density profiling (CLPDP), a novel density gradient ultracentrifugation technique.

The fecal microbiome of dogs with exocrine pancreatic insufficiency.

Exocrine pancreatic insufficiency (EPI) in dogs is a syndrome of inadequate synthesis and secretion of pancreatic enzymes. Small intestinal bacterial dysbiosis occurs in dogs with EPI, and is reversed with pancreatic enzyme therapy. However, there are no studies evaluating the fecal microbiome of dogs with EPI.

Purification and partial characterization of α1-proteinase inhibitor in the common marmoset (Callithrix jacchus).

Fecal alpha1-proteinase inhibitor (α1-PI) concentration has been to diagnose enteric protein loss in dogs and cats. Chronic lymphocytic enteritis is commonly seen in the marmoset (Callithrix jaccus) and is characterized by hypoalbuminemia. As a prelude to immunoassay development for detecting enteric protein loss, marmoset serum α1-PI was purified using immunoaffinity chromatography and ceramic hydroxyapatite chromatography.
