Nasopharyngeal stenosis in cats: a retrospective study of 21 cases comparing endoscopic and surgical treatment (2018-2022).

Objectives: Feline nasopharyngeal stenosis (NPS) is an uncommon disease in cats. The aim of this study was to compare the outcome with endoscopic and surgical treatments.

Methods: In this retrospective study, medical records were searched for cases of NPS and cases were divided into three groups: endoscopic treatment (balloon dilation); surgical treatment; or no treatment.

Development and validation of a novel clinical scoring system for short-term prediction of death in dogs with acute pancreatitis.

Background: Acute pancreatitis (AP) is associated with a high death rate in dogs, but accurate predictors of early death are still lacking.

Objectives: To develop a scoring system for prediction of short-term case fatality in dogs with AP.

Animals: One hundred sixty-nine dogs with AP including 138 dogs in the training cohort and 31 dogs in the validation cohort.

Fibrinogen deficiency in a dog - a case report.

Background: Among coagulation disorders, primary fibrinogen deficiency is very rare in dogs. It is divided into hypofibrinogenemia, afibrinogenemia and dysfibrinogenemia. Afibrinogenemia has been described in three dogs.

Circadian and postprandial variation in plasma citrulline concentration in healthy dogs.

Objective: To evaluate circadian and postprandial variations in plasma citrulline concentration in healthy dogs.

Animals: 8 healthy Beagles.

Procedures: Blood samples were collected from dogs after 12 hours of food withholding (0 hours; 8:00 am) and then every 2 hours for 12 hours (until 8:00 pm) and again at 24 hours (8:00 am the next day).

The effect of a pre-anesthetic infusion of amino acids on body temperature, venous blood pH, glucose, creatinine, and lactate of healthy dogs during anesthesia.

Objective: To evaluate the effect of preanesthetic, intravenous (IV) amino acids on body temperature of anesthetized healthy dogs.

Study Design: Randomized, experimental, crossover study.

Animals: Eight mixed-breed dogs approximately 2 years of age weighing 20.

Manual ventilation therapy and aggressive potassium supplementation in the management of respiratory failure secondary to severe hypokalaemia in a cat with exocrine pancreatic insufficiency.

A domestic shorthair cat was referred for progressive muscle weakness and dyspnoea. The cat had a 2-month history of severe weight loss, small intestinal diarrhoea, polyphagia and polyuria/polydipsia. Biochemical analysis and venous blood gas evaluation revealed severe hypokalaemia [1.

Incidence of bacteremia following upper gastrointestinal endoscopy and biopsy in healthy dogs before, during, and after treatment with omeprazole.

Objective: To determine the incidence of bacteremia, as detected by routine methods for bacterial culture of blood samples, following routine endoscopic biopsy of the stomach and duodenum in healthy research dogs and to determine whether treatment with omeprazole administration affected the incidence of bacteremia.

Animals: 8 healthy purpose-bred research dogs.

Procedures: All dogs underwent gastroduodenoscopy with biopsy at 4 points: twice prior to treatment with omeprazole, once following 15 days of omeprazole treatment (20 mg, PO, q 12 h), and once 14 days after treatment ceased.

Comparison of three different methods to prevent heat loss in healthy dogs undergoing 90 minutes of general anesthesia.

Objective: To compare a towel under, a warm water pad under or a forced warm air blanket over dogs as techniques to reduce heat loss during a standardized anesthetic.

Study Design: Prospective, randomized, crossover study.

Animals: Eight, healthy, mixed breed dogs weighing 16.

Effect of the proton pump inhibitor omeprazole on the gastrointestinal bacterial microbiota of healthy dogs.

The effect of a proton pump inhibitor on gastrointestinal (GI) microbiota was evaluated. Eight healthy 9-month-old dogs (four males and four females) received omeprazole (1.1 mg kg(-1) ) orally twice a day for 15 days.

Laboratory tests for diagnosis of gastrointestinal and pancreatic diseases.

The panel of laboratory tests available for diagnosis of gastrointestinal (GI) diseases in dogs and cats is wide, and, recently, several new tests have been developed. This article will focus on advances in laboratory tests that are available for the general practitioner for diagnosis of GI diseases. Laboratory tests for diagnosis of gastric and intestinal infectious diseases include fecal parasite screening tests, enzyme-linked immunosorbent assays for parvoviral enteritis, and some specific bacterial tests like fluorescent in situ hybridization for identification of specific bacteria attached to the intestinal epithelial cells.

Protein-losing enteropathies in dogs.

Protein-losing enteropathy is common in dogs but rare in cats. In the vast majority of cases, it is associated with inflammatory bowel disease, intestinal lymphoma, or intestinal lymphangiectasia. The diagnosis is based on identification of hypoalbuminemia and ruling out urinary loss and liver failure.

Disseminated nocardiosis caused by Nocardia abscessus in a dog.

A 4-year-old female spayed Bichon Frise dog that had been receiving cyclosporine A per os 3 times per week for 2 months to control allergic dermatitis developed lethargy, anorexia, fever, and multiple firm subcutaneous masses. Pyogranulomatous inflammation with branching nonseptate filamentous organisms approximately 2 μm in diameter, presumptively fungal organisms, was diagnosed by cytologic evaluation of fine-needle aspirates from several masses. A partially acid-fast actinomycete was cultured from 2 of the masses.

A laparoscopic-sutured gastropexy technique in dogs: mechanical and functional evaluation.

Objective: To describe a laparoscopic-sutured gastropexy technique in dogs and evaluate the tensile strength of the adhesion and effects on gastric function.

Study Design: Experimental study.

Animals: Female beagle dogs (n=7).

Fractional excretion tests: a critical review of methods and applications in domestic animals.

The fractional excretion (FE) of a constituent by the kidney is the fraction of the amount filtered by the glomerulus, which is excreted into urine. It is mostly determined for electrolytes, and is expressed as the ratio of the clearance of a given electrolyte to creatinine clearance. The main physiologic factors affecting FE variation are species, age, and the alimentary supply of electrolytes.
