Anal glands are located on either side of the anus and normally produce secretions that are pushed when feces is evacuated from the rectum. An anal sac tumor is a tumor of made up of cells originating from the glands of the anal sac. These tumors can spread and therefore staging is recommended prior to surgery. To diagnose these tumors, a fine needle aspirate can be placed from the outside and into the anal sac to retrieve cells. After surgery, chemotherapy may be considered. Radiation therapy has also been considered as a primary or secondary treatment option.
Anemia is a medical term referring to a reduced number of circulating red blood cells, hemoglobin, or both. It is not a specific disease but rather it is the result of some other disease process or condition. The most easily observed and common clinical sign of anemia is a loss of the normal pink color of the gums. Several tests are performed on blood samples to diagnose anemia. If your cat's anemia is so severe that it is life threatening, a blood transfusion will be needed.
The word anesthesia comes from the Greek meaning "lack of sensation". Anesthesia is accomplished by administering drugs that depress nerve function. With general anesthesia, the patient is made unconscious for a short period. During this unconscious state, there is muscular relaxation and a complete loss of pain sensation.
The pupil constricts or dilates (enlarges) according to the amount of light that enters the eyes, with both pupils normally dilating in dim light and constricting in bright light. Anisocoria is a condition in which the pupils of the cat's eyes are different sizes. Anisocoria is a sign of an underlying disease condition and therefore there are several different causes. Your veterinarian will begin by conducting a physical examination of your cat, including a detailed examination of the structures of the eye. The treatment and prognosis of anisocoria depends entirely on the underlying cause of the condition, and specific treatment will be tailored specifically to the diagnosis.
A cat that is not wanting to eat or is not eating, is a cat who has a potentially life-threatening medical condition. Many conditions can lead to the inability of your cat to eat or for your cat to lose her appetite completely. It is important to find the underlying cause so that an appropriate treatment plan can be created. Appetite stimulants may be prescribed and in some cases a feeding tube may be placed by your veterinarian. Decreased food intake or any change in eating habits warrants investigation by your veterinarian.
Different animals have different levels of susceptibility to anthrax infection. In general, herbivores are found to be more susceptible to anthrax than carnivores. Under normal circumstances, cases of anthrax in cats are very rare and cats seem relatively resistant to infection, especially under normal circumstances.
Antibiotic resistant bacterial infections are bacterial infections that are minimally or no longer responsive to commonly used antibiotics. In other words, these bacteria are resistant to antibiotics - they cannot be killed and their growth cannot be stopped. Antibiotic resistant bacterial infections most commonly affect the skin, the gastrointestinal tract, the urinary tract, or the respiratory tract.
Antibodies are specialized proteins, also called immunoglobulins that are primarily found in the bloodstream. They are produced by specialized white blood cells called plasma cells, a form of lymphocyte.
An antioxidant is any compound, whether vitamin, mineral, nutraceutical, or herb that protects against cellular damage from reactive oxygen species, including free radicals, single oxygen atoms and hydrogen peroxide. Some of the more well-known antioxidants include ascorbic acid (Vitamin C), alpha-tocopherol (Vitamin E), beta-carotene, and enzymes such as catalase, superoxide dismutase and glutathione peroxidase.
Aortic stenosis is a heart disease that is present at birth. Cats affected with aortic stenosis have a narrowing at the aortic valve of the heart. This narrowing forces the heart to work abnormally hard to force blood through the narrowed valve. The clinical signs of aortic stenosis vary depending on how severe the stenosis is; some cats remain asymptomatic throughout their life, while other cats begin showing clinical signs at an early age and can experience sudden death. The treatment of aortic stenosis depends upon the severity of the condition.
