Body Temperature Fluctuation After Ovariohysterectomy in Dogs in Luteal Phase, Inactive Phase and Pyometra: A Clinical Study of 77 Cases.

Progesterone (P4) has a thermogenic effect in the bitch and a decrease in P4 has been associated with a mild transient decrease in body temperature. The aim of this study was to investigate the presence, the extent and the pattern of possible hypothermia after ovariohysterectomy (OHE) in healthy dogs in luteal phase and in bitches with pyometra that underwent therapeutic OHE. Sixty-two healthy dogs and 15 dogs with pyometra that underwent standardized OHE were included.

Evaluation of blood T-lymphocyte subpopulations involved in host cellular immunity in dogs with mammary cancer.

Cancer-bearing patients are often immunosuppressed. In dogs with mammary or other cancers, various alterations in blood cell populations involved in host cellular immunity have been reported; among these cell populations some T-lymphocyte subsets play an important role against cancer. The purpose of the present study was to investigate any alterations in circulating T-lymphocyte subpopulations involved in cellular immunity in bitches with mammary cancer, in comparison to age-matched healthy intact bitches.

Gastro-oesophageal reflux in large-sized, deep-chested versus small-sized, barrel-chested dogs undergoing spinal surgery in sternal recumbency.

Objective: The aim of this study was to investigate whether an increased frequency of gastro-oesophageal reflux (GOR) is more common in large-sized, deep-chested dogs undergoing spinal surgery in sternal recumbency than in small-sized, barrelchested dogs.

Study Design: Prospective, cohort study.

Animals: Nineteen small-sized, barrel-chested dogs (group B) and 26 large-sized, deep-chested dogs (group D).

Anesthetic management of a 4-month-old red fox (Vulpes vulpes) for orthopedic surgery.

A 4-mo-old red fox (Vulpes vulpes) was found recumbent after a vehicular accident. Radiology revealed several limb fractures and the fox underwent surgery after 24 hr of initial stabilization. Premedication consisted of dexmedetomidine and morphine.

The effect of the stage of the ovarian cycle (anoestrus or dioestrus) and of pregnancy on the incidence of gastro-oesophageal reflux in dogs undergoing ovariohysterectomy.

Objective: To investigate the potential association of increased blood progesterone (P4 ) concentrations and/or late pregnancy with the incidence of gastro-oesophageal reflux (GOR), in healthy bitches undergoing ovariohysterectomy under general anaesthesia during anoestrus or dioestrus or during the second half of pregnancy.

Study Design: Prospective observational study.

Animals: Ninety-four healthy, female, dogs, aged 1-8 years presented for elective ovariohysterectomy.
