Abstract

BACKGROUND:Due to the limited information and lack of studies on neoplasms in domestic ruminants, i.e., cattle, sheep, and goats, and domestic swine, the objective of the present study was to systematically review the scientific literature to verify the occurrence, type, organ system, and organs most affected by neoplasms in these animals.

METHODS:The recommendations of the PRISMA methodology were followed for the elaboration of this study. The research consisted of a systematic review of neoplasms in domestic cattle, sheep, goats, and swine.

RESULTS:The number of neoplasms found was 1873. The most affected organ system was the integumentary system with 35.0%, followed in descending order by the alimentary system with 16.90%, the hematopoietic system with 13.50%, the special senses (i.e., eyes and ears) with 10.51%, the female and male genital systems with 7.31%, the urinary system with 4.38%, the liver and biliary system with 3.152%, the endocrine glands with 3.91%, the respiratory system with 2.67%, the nervous system with 2.35%, bones and joints with 0.43%, muscles and tendons with 0.37%, the cardiovascular system with 0.21%, and the pancreas with 0.16%. Of the animals with neoplasms studied, cattle were affected in 69.80% of cases, goats in 10.52%, sheep in 10.46%, and swine in 9.18%. In all species, the most frequent neoplasms were squamous cell carcinomas in ruminants, while melanoma was the most frequent in swine. Few studies carried out in slaughterhouses were found, and the existing ones referred to cattle and swine. No data were found on economic losses with carcass condemnation.

CONCLUSIONS:In view of the above, it is necessary to carry out extensive and detailed studies that provide knowledge about the impact of neoplasms on the production and condemnation of carcasses in domestic cattle, sheep, goats, and swine and the respective risk factors.

From the Cat’s Point of View: Creating a Cat Friendly Veterinary Environment
Prepare the examination table in advance with warm blankets sprayed with synthetic feline pheromones placed on nonslip surfaces (e.g., yoga mats). Spraying synthetic feline pheromones on the examination table 15 minutes before the physical examination has been shown to lower stress levels compared with placebo Synthetic feline pheromone diffusers are also recommended.

A review of prevention and management of castration complications
Despite castration being one of the most frequently performed elective equine surgical procedures, complication rates are high and range from severe life-threatening conditions to mild complications that are of no consequence to the horse. This article will briefly review strategies to prevent complications and surgical castration techniques before reviewing, in-depth, the following complications: excessive scrotal swelling and seroma formation, scrotal infection, septic funiculitis, septic peritonitis, haemorrhage, evisceration, omental prolapse, pyrexia, tetanus, penile trauma, hydrocele, signs of colic, and continued stallion-like behaviour.

Spotting the Pattern: A Review on White Coat Color in the Domestic Horse.
only two genetic markers are used to determine a horse's base coat color, whereas over 50 genetic variations have been discovered to cause white patterning in horses. Some of these white-causing mutations are benign and beautiful, while others have a notable impact on horse health. In this review, we explore, in detail, the etiology of white spotting and its overall effect on the domestic horse to Spot the Pattern of these beautiful (and sometimes dangerous) white mutations.

Retrospective Study of the Prevalence, Histopathology, Therapy, and Survival Time of Neoplastic Disease in Fish.
The species with the highest neoplasia prevalence was koi (18.5%), followed by goldfish (10.8%). The eye was the most commonly reported site for a primary neoplasm (8.4%), and the most prevalent diagnosis across all organ systems was soft tissue sarcoma (26.2%). Only 13 patients in this study (2.9%) received any form of treatment, with a mean survival time of 8.85 months post-treatment.

Wavy changes in the whiskers of domestic cats are correlated with feline leukemia virus infection.
The prevalence of wavy whiskers (WW) was significantly correlated with FeLV antigen positivity in the blood. Of 56 cases with WW, 50 (89.3%) were serologically positive for FeLV. The significant association between WW and serological FeLV positivity was also confirmed by multivariate analysis. In WW, narrowing, degeneration, and tearing of the hair medulla were observed. Mild infiltration of mononuclear cells in the tissues, but no degeneration or necrosis, was found. By immunohistochemistry, FeLV antigens (p27, gp70, and p15E) were observed in various epithelial cells including the sinus hair follicular epithelium of the whisker.
