An aural hematoma is a collection of blood between the cartilage and skin of the ear flap. It is most usually caused by trauma but can also be due to a bleeding disorder. Hematomas in dogs can be treated in different ways but should be treated early to minimize pain and disfigurement. If an underlying cause is determined such as otitis externa, this needs to be treated as well. Hematomas may eventually resolve on their own, but there is a risk of cauliflower ear and they are painful, so prompt treatment is recommended.

Hemophilia A and B are clotting disorders involving a deficiency of a specific clotting factor (A: Factor VIII, B: Factor IX) needed for appropriate homeostasis. They are caused by a sex-linked recessive genetic mutation. Affected dogs will show inappropriate hemorrhage including bruising, lameness induced by bleeding into joints and body cavity hemorrhage. It can be diagnosed with a slow APTT and demonstrating low levels of the factor involved. Hemophilia A is more common than B and is generally, more severe. Because it is sex-linked recessive, males are more likely to be affected than females but females still act as carriers, so genetic screening is important prior to breeding to prevent this disease.

Hepatic encephalopathy is a neurologic condition in cats and dogs that is caused by an underlying liver condition. It can cause lethargy, seizures, problems with balance and coordination, and coma. Common causes, methods to diagnose the condition, and its treatment options are explained in this handout.

Hepatic lipidosis, also known as fatty liver syndrome, is unique to cats and is one of the most common liver diseases seen in cats. Usually a cat with hepatic lipidosis has recently gone through a period of anorexia (little or no eating) for 3 to 4 consecutive days. Diagnosis of hepatic lipidosis is made from blood tests that demonstrate poor liver function and/or from a liver biopsy or fine needle aspirate. Hepatic lipidosis is treatable with aggressive nutritional support until a normal appetite returns. Treating the underlying initial cause of the inappetence is also essential for full recovery.

This handout explains hepatic microvascular dysplasia, a condition where microscopic blood vessels within the liver are underdeveloped or absent, resulting in decreased blood flow to the liver. As a result, the liver is less capable of dealing with toxins or producing the vital proteins needed for good health. Methods to diagnose the condition and its treatment options are also explained.

Hepatoid gland tumors are a type of cancer that develop from the sebaceous (sweat) glands of the skin. The most common location for these tumors to develop is the perianal area, and the most common tumor is the perianal adenoma. Perianal adenocarcinomas, and rarely perianal epitheliomas may also occur. These tumors appear as one or more small, round, pink, hairless, slow-growing nodules around the anus, and can sometimes ulcerate and become infected. Malignant tumors can grow much bigger and faster, invade the underlying tissue, and metastasize. Diagnosis may be made by fine needle aspiration, biopsy, or full excision of the tumor. Staging is recommended for adenocarcinomas. Treatment may involve surgical removal along with neutering, cryotherapy, laser ablation, radiotherapy, chemotherapy, and occasionally hormone therapy. The prognosis is good with perianal adenomas, fair to poor with adenocarcinomas, and generally good with epitheliomas.

Hepatozoonosis in dogs is caused by ingestion of one of two organisms: H. americanum and H. canis. Both parasites are more common in the southern United States. The clinical sign and treatments for dogs with hepatozoonosis differ depending on the parasite species causing the infection. In either case, with appropriate treatment, the prognosis is generally good.

Fight Wound Infections in Cats
Los gatos tienen un instinto muy territorial. Se pelean con otros gatos para proteger su territorio o para adquirir más territorio. Por tanto, las heridas por peleas son muy frecuentes en gatos. Se considera que el 90 % de las heridas infectadas en gatos se producen por mordeduras de otros gatos.
