Head Pressing
Head pressing is a veterinary condition characterized by pressing the head against a wall or pushing the face into a corner for no apparent reason. This condition is seen in dogs, cats, cows, horses, and goats. Head pressing is usually a sign of a neurological disorder, especially of the forebrain (e.g., prosencephalon disease), or of toxicity due to liver damage, such as portosystemic shunt and hepatic encephalopathy. It should be distinguished from bunting, which is a normal behavior found in healthy animals. Possible causes * Prosencephalon disease * Liver shunt * Brain tumor * Metabolic disorder (e.g., hyponatremia or hyperatremia) * Stroke * Infection of the nervous system (rabies, parasites, bacterial, viral or fungal infection) * Head trauma Liver neurotoxicity A liver shunt is a congenital or acquired condition that may lead to toxicity and head pressing. Additional symptoms include drooling and slow maturation early in development. Middle-aged and older animals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Veterinary
Veterinary medicine is the branch of medicine that deals with the prevention, management, diagnosis, and treatment of disease, disorder, and injury in animals. Along with this, it deals with animal rearing, husbandry, breeding, research on nutrition, and product development. The scope of veterinary medicine is wide, covering all animal species, both domesticated and wild, with a wide range of conditions that can affect different species. Veterinary medicine is widely practiced, both with and without professional supervision. Professional care is most often led by a veterinary physician (also known as a veterinarian, veterinary surgeon, or "vet"), but also by paraveterinary workers, such as veterinary nurses or technicians. This can be augmented by other paraprofessionals with specific specialties, such as animal physiotherapy or dentistry, and species-relevant roles such as farriers. Veterinary science helps human health through the monitoring and control of zoonotic disease (i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyponatremia
Hyponatremia or hyponatraemia is a low concentration of sodium in the blood. It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. Symptoms can be absent, mild or severe. Mild symptoms include a decreased ability to think, headaches, nausea, and poor balance. Severe symptoms include confusion, seizures, and coma; death can ensue. The causes of hyponatremia are typically classified by a person's body fluid status into low volume, normal volume, or high volume. Low volume hyponatremia can occur from diarrhea, vomiting, diuretics, and sweating. Normal volume hyponatremia is divided into cases with dilute urine and concentrated urine. Cases in which the urine is dilute include adrenal insufficiency, hypothyroidism, and drinking too much water or too much beer. Cases in which the urine is concentrated include syndrome of inappropriate antidiuretic hormone secretion (SIADH). High vo ...

Bovine Diseases
Bovines (subfamily Bovinae) comprise a diverse group of 10 genera of medium to large-sized ungulates, including cattle, bison, African buffalo, water buffalos, and the four-horned and spiral-horned antelopes. The evolutionary relationship between the members of the group is still debated, and their classification into loose tribes rather than formal subgroups reflects this uncertainty. General characteristics include cloven hooves and usually at least one of the sexes of a species having true horns. The largest extant bovine is the gaur. In many countries, bovid milk and meat is used as food by humans. Cattle are kept as livestock almost everywhere except in parts of India and Nepal, where they are considered sacred by most Hindus. Bovids are used as draft animals and as riding animals. Small breeds of domestic bovid, such as the Miniature Zebu, are kept as pets. Bovid leather is durable and flexible and is used to produce a wide range of goods including clothing and bags. Sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canine Brain Tumors
Cancer of the nervous system is common in domestic canids, and includes primary neoplasia of the peripheral nervous system, primary neoplasia of the central nervous system and various metastatic cancers. Some of the most common of the central nervous system tumors are several types of primary (originating from brain tissue) canine brain tumors. Examples of these include: meningiomas, astrocytomas, glioblastomas, oligodendromas, choroid plexus papillomas, and pituitary adenomas. Breeds predisposed to brain tumors include: Boxer Dog, Pug, English Bull Dog, Boston Terrier, and Golden Retrievers. Common canine brain tumors Meningiomas Meningiomas (arising from the meninges, a neural crest-derived cell) are the most common brain tumor of dogs, accounting for 40% of all primary brain tumors. Golden Retrievers as well as other dolichocephalic (long-nosed) breeds are particularly susceptible. Astrocytomas and glioblastomas Astrocytomas are the most common neuroectodermal tumor ...

Bovine Malignant Catarrhal Fever
Bovine malignant catarrhal fever (BMCF) is a fatal lymphoproliferative disease caused by a group of ruminant gamma herpes viruses including ''Alcelaphine gammaherpesvirus 1'' (AlHV-1) and ''Ovine gammaherpesvirus 2'' (OvHV-2) These viruses cause unapparent infection in their reservoir hosts (sheep with OvHV-2 and wildebeest with AlHV-1), but are usually fatal in cattle and other ungulates such as deer, antelope, and buffalo. In Southern Africa the disease is known as ''snotsiekte'', from the Afrikaans. BMCF is an important disease where reservoir and susceptible animals mix. There is a particular problem with Bali cattle in Indonesia, bison in the US and in pastoralist herds in Eastern and Southern Africa. Disease outbreaks in cattle are usually sporadic although infection of up to 40% of a herd has been reported. The reasons for this are unknown. Some species appear to be particularly susceptible, for example Pére David's deer, Bali cattle and bison, with many deer dying with ...

Bovine Alphaherpesvirus 5
''Bovine alphaherpesvirus 5'' (BoHV-5) is a virus species of the genus ''Varicellovirus'' and subfamily ''Alphaherpesvirinae''. It causes meningoencephalitis and bovine respiratory disease, respiratory disease in cattle and sheep. As with all herpes viruses latent infection can occur, with recrudescence at times of stressed and/or immunosuppression. Sites of latency include the CNS and mucosae of the nose and trachea. The disease has been documented in South America, the United States, Australia, Germany and Hungary. Caused by: ''BHV-5 – Bovine Encephalitis Virus – Bovine Encephalitis Herpesvirus'' Disease is most common in calves up to ten months of age. Clinical signs and diagnosis Signs of respiratory disease include tachycardia and tachypnea with pyrexia, dyspnea, mucoid nasal discharge, hypersalivation and abnormal lung sounds. Systemic signs such as lethargy and Anorexia (symptom), anorexia are seen. Neurological signs are normally acute. These signs include opisth ...

Meningoencephalitis
Meningoencephalitis (; from ; ; and the medical suffix ''-itis'', "inflammation"), also known as herpes meningoencephalitis, is a medical condition that simultaneously resembles both meningitis, which is an infection or inflammation of the meninges, and encephalitis, which is an infection or inflammation of the brain. Signs and symptoms Signs of meningoencephalitis include unusual behavior, personality changes, and thinking problems. Symptoms may include headache, fever, pain in neck movement, light sensitivity, and seizure An epileptic seizure, informally known as a seizure, is a period of symptoms due to abnormally excessive or synchronous neuronal activity in the brain. Outward effects vary from uncontrolled shaking movements involving much of the body with los .... Causes Causative organisms include protozoans, virus, viral and bacterial pathogens.

Encephalitis
Encephalitis is inflammation of the brain. The severity can be variable with symptoms including reduction or alteration in consciousness, headache, fever, confusion, a stiff neck, and vomiting. Complications may include seizures, hallucinations, trouble speaking, memory problems, and problems with hearing. Causes of encephalitis include viruses such as herpes simplex virus and rabies virus as well as bacteria, fungi, or parasites. Other causes include autoimmune diseases and certain medications. In many cases the cause remains unknown. Risk factors include a weak immune system. Diagnosis is typically based on symptoms and supported by blood tests, medical imaging, and analysis of cerebrospinal fluid. Certain types are preventable with vaccines. Treatment may include antiviral medications (such as acyclovir), anticonvulsants, and corticosteroids. Treatment generally takes place in hospital. Some people require artificial respiration. Once the immediate problem is under co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liver Shunt
A portosystemic shunt or portasystemic shunt (medical subject heading term; PSS), also known as a liver shunt, is a bypass of the liver by the body's circulatory system. It can be either a congenital (present at birth) or acquired condition and occurs in humans as well as in other species of animals. Congenital PSS are extremely rare in humans but are relatively common in dogs. Thus a large part of medical and scientific literature on the subject is grounded in veterinary medicine. Background Blood leaving the digestive tract is rich in nutrients, as well as in toxins, which under normal conditions undergo processing and detoxification in the liver. The liver's position downstream to the intestines in the body's circulatory system - the hepatic portal vein conveys blood from the intestines to the liver - allows it to filter this nutrient rich blood before it passes to the rest of the body. The presence of a shunt, a bypass of the liver, causes blood to flow directly to the hear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
