Noninvasive hydrostatic reduction of an ileocecocolic intussusception in a puppy.

A 5-week-old male intact Golden Retriever puppy was presented for a history of vomiting and diarrhea with hematochezia. Ultrasound findings confirmed the presence of an ileocecocolic intussusception. Surgical correction was declined because of financial concerns.

Ultrasonographic and clinicopathologic features of segmental dilatations of the common bile duct in four cats.

Case Series Summary: This case series documents ultrasonographic and clinicopathologic features of four cats with marked segmental dilatations of the common bile duct (CBD). All cats had additional ultrasonographic changes to the hepatobiliary system, including hepatomegaly, tubular to saccular intra/extrahepatic biliary duct dilatation and biliary debris accumulation. Based on all available data the presence of extrahepatic biliary duct obstruction (EHBDO) was ruled out in 3/4 cases and was equivocal in one case.

Gastroduodenal Ulceration in Small Animals: Part 1. Pathophysiology and Epidemiology.

Gastroduodenal ulceration in small animals is a complex and important comorbidity that occurs when the physiological homeostasis of the gastrointestinal tract is disrupted secondary to administration of medications or the presence of local or systemic diseases. The aim of this article is to provide a comprehensive review of the veterinary literature regarding the pathophysiology, epidemiology, and risk factors associated with gastroduodenal ulceration in small animals. Pertinent concepts from the human literature will be integrated into the discussion.

Gastroduodenal Ulceration in Small Animals: Part 2. Proton Pump Inhibitors and Histamine-2 Receptor Antagonists.

In the first part of this review, we discussed the pathophysiology and epidemiology of gastric acid secretion and the epidemiology of gastroduodenal ulceration in dogs and cats. In this section, we discuss the pharmacology and evidence-based clinical use of histamine-2 receptor antagonists and proton pump inhibitors.

Ultrasonographic and clinicopathological features of pyloroduodenal adenomatous polyps in cats.

Objectives The aim of the study was to report the ultrasonographic and clinicopathological findings in cats with confirmed pyloroduodenal adenomatous polyps. Methods Clinicopathological data, ultrasonographic and histopathological findings were collected retrospectively from medical records. Results Pyloroduodenal polyps appeared as small moderately echogenic and homogeneous nodules filling most of the proximal duodenal or pyloroduodenal lumen.

Elevation of neutrophil gelatinase-associated lipocalin (NGAL) in non-azotemic dogs with urinary tract infection.

Neutrophil gelatinase-associated lipocalin (NGAL) is a promising biomarker in humans and dogs with kidney disease. This protein is expressed by many cells including renal tubular cells and neutrophils. The aim of this study was to evaluate the effect of urinary tract infection (UTI) on urinary NGAL (uNGAL) concentration in dogs.
