Association between previous splenectomy and gastric dilatation-volvulus in dogs: 453 cases (2004-2009).

Objective: To evaluate the association between previous splenectomy and gastric dilatation-volvulus (GDV) in dogs.

Design: Multi-institutional retrospective case-control study. Animals-151 dogs treated surgically for GDV and 302 control dogs with no history of GDV.

Evaluation of coagulation in dogs with partial or complete extrahepatic biliary tract obstruction by means of thromboelastography.

Objective: To characterize in vitro coagulation status in a cohort of dogs with extrahepatic biliary tract obstruction (EHBO) and to evaluate these patients for hypercoagulability by means of thromboelastography.

Design: Prospective cohort study. Animals-10 dogs with EHBO and 19 healthy control dogs.

Alterations in the hemostatic profiles of dogs with naturally occurring septic peritonitis.

Objective: To characterize derangements in the hemostatic profiles of dogs with naturally occurring septic peritonitis and determine if such derangements were predictive of survival.

Design: Prospective, observational single cohort study.

Setting: University veterinary teaching hospital.

Heterodimerization studies of calix[4]arene derivatives in polar solvents.

[reaction: see text] Several calix[4]arene derivatives propylated on the lower rim and substituted on the upper rim with amino or carboxyl groups have been synthesized. Examples include calixarenes substituted with alanino (C- and N-linked), amino, carboxy, carboxyphenyl, and amidino groups. The self-assembly of these derivatized calixarenes into heterodimers has been studied by NMR in DMSO-d(6) or CD(3)OD with 5% aqueous phosphate buffer.

Intestinal choristoma in the midcervical region of a dog.

A 5-year-old, neutered male, mixed-breed dog was evaluated for a fluctuant mass in the right midcervical region. The mass recurred following aspiration of its contents and after removal of the right sublingual and mandibular salivary glands. The lateral midcervical location of the mass and the serous nature of the fluid within the mass were inconsistent with a salivary mucocele.

Volvulus of the colon in four dogs.

Four dogs were examined because of vomiting of 7 to 48 hours' duration. Gas-distended segments of intestine were identified radiographically in all dogs, but the affected portion of the intestinal tract could not always be identified as the colon. Volvulus of the colon was diagnosed during surgery in all 4 dogs.
