Myxedema's characteristic physical sign is non-pitting edema, in contrast to pitting edema. [1] Myxedema can also occur in the lower leg (pretibial myxedema) and behind the eyes (exophthalmos). [citation needed] Severe cases, requiring hospitalization can exhibit signs of hypothermia, hypoglycemia, hypotension, respiratory depression, and coma.
Peripheral edema is edema (accumulation of fluid causing swelling) in tissues perfused by the peripheral vascular system, usually in the lower limbs. In the most dependent parts of the body (those hanging distally ), it may be called dependent edema.
Periorbital edema. Periorbital puffiness, also known as puffy eyes, or swelling around the eyes, is the appearance of swelling in the tissues around the eyes, called the orbits. It is almost exclusively caused by fluid buildup around the eyes, or periorbital edema. Minor puffiness usually detectable below the eyes only is often called eye bags.
Edema may be described as pitting edema, or non-pitting edema. [32] Pitting edema is when, after pressure is applied to a small area, the indentation persists after the release of the pressure. Peripheral pitting edema, as shown in the illustration, is the more common type, resulting from water retention.
White dog shaker syndrome causes full body tremors in small, white dog breeds. It is most common in West Highland White Terriers, Maltese, Bichons, and Poodles. [6] Wobbler disease (cervical instability) is a condition of the cervical vertebrae that causes an unsteady gait and weakness in dogs.
Pretibial myxedema is almost always preceded by the ocular signs found in Graves' disease. [3] It usually presents itself as a waxy, discolored induration of the skin—classically described as having a so-called peau d'orange (orange peel) appearance—on the anterior aspect of the lower legs, spreading to the dorsum of the feet, or as a non-localised, non-pitting edema of the skin in the ...
Dog with atopic dermatitis, with signs around the eye created by rubbing. Atopy is a hereditary [3] and chronic (lifelong) allergic skin disease. Signs usually begin between 6 months and 3 years of age, with some breeds of dog, such as the golden retriever, showing signs at an earlier age.
