Ectropion
Ectropion is a medical condition in which the lower eyelid turns outwards. It is one of the notable aspects of newborns exhibiting congenital Harlequin-type ichthyosis, but ectropion can occur due to any weakening of tissue of the lower eyelid. The condition can be repaired surgically. Ectropion is also found in dogs as a genetic disorder in certain breeds. Causes *Congenital *Aging *Scarring *Mechanical *Allergic * Facial nerve palsy *Anti-cancer treatments such as erlotinib, cetuximab, and panitumumab, which block the function of EGFR (the epidermal growth factor receptor). Diagnosis Ectropion can usually be diagnosed with a routine eye exam and physical. The eyelid's muscle tone and tightness can be assessed by pulling gently on the eyelid. Ectropion in dogs Ectropion in dogs usually involves the lower eyelid. Often the condition has no symptoms, but tearing and conjunctivitis may be seen. Breeds associated with ectropion include the Cocker Spaniel, the Saint Bernard, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cervical Erosion
Cervical ectropion is a condition in which the cells from the 'inside' of the cervical canal, known as glandular cells (or columnar epithelium), are present on the 'outside' of the vaginal portion of the cervix. The cells on the 'outside' of the cervix are typically squamous epithelial cells. Where the two cells meet is called the transformation zone, also known as the stratified squamous epithelium. Cervical ectropion can be grossly indistinguishable from early cervical cancer and must be evaluated by a physician to determine risks and prognosis. It may be found incidentally when a vaginal examination (or pap smear test) is done. The area may look red because the glandular cells are red. While many women are born with cervical ectropion, it can be caused by a number of reasons, such as: *Hormonal changes, meaning it can be common in young women *Using oral contraceptives *Pregnancy. Signs and symptoms Cervical ectropion can be associated with excessive, non-purulent vagina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clumber Spaniel
The Clumber Spaniel is a breed of dog of the spaniel type, developed in the United Kingdom. It is the largest of the spaniels, and comes in predominantly white with either lemon or orange markings. The name of the breed is taken from Clumber Park in Nottinghamshire where the breed was first developed. It is a gundog that specialises in hunting in heavy cover. They are gentle and loyal, and can act aloof with strangers. They have several habits which could be considered disadvantages, including a constant shedding of its coat and snoring. The history of Consort, Prince Albert, King Edward VII and King George V. They were introduced into Canada in 1844, and in 1884 became one of the first ten breeds recognised by the American Kennel Club. The breed can suffer from a variety of breed-specific ailments varying in severity from temporary lameness due to bone growth whilst young to hip dysplasia or spinal disc herniation.

Harlequin-type Ichthyosis
Harlequin-type ichthyosis is a genetic disorder that results in thickened skin over nearly the entire body at birth. The skin forms large, diamond/trapezoid/rectangle-shaped plates that are separated by deep cracks. These affect the shape of the eyelids, nose, mouth, and ears and limit movement of the arms and legs. Restricted movement of the chest can lead to breathing difficulties. These plates fall off over several weeks. Other complications can include premature birth, infection, problems with body temperature, and dehydration. The condition is the most severe form of ichthyosis, a group of genetic disorders characterised by scaly skin. Harlequin-type ichthyosis is caused by mutations in the ''ABCA12'' gene. This gene codes for a protein necessary for transporting lipids out of cells in the outermost layer of skin. The disorder is autosomal recessive and inherited from parents who are carriers. Diagnosis is often based on appearance at birth and confirmed by genetic testin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Entropion
Entropion is a medical condition in which the eyelid (usually the lower lid) folds inward. It is very uncomfortable, as the eyelashes continuously rub against the cornea causing irritation. Entropion is usually caused by genetic factors. This is different from when an extra fold of skin on the lower eyelid causes lashes to turn in towards the eye ( epiblepharon). In epiblepharons, the eyelid margin itself is in the correct position, but the extra fold of skin causes the lashes to be misdirected. Entropion can also create secondary pain of the eye (leading to self trauma, scarring of the eyelid, or nerve damage). The upper or lower eyelid can be involved, and one or both eyes may be affected. When entropion occurs in both eyes, this is known as "bilateral entropion". Repeated cases of trachoma infection may cause scarring of the inner eyelid, which may cause entropion. In human cases, this condition is most common to people over 60 years of age. Symptoms Symptoms of entropion incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornea
The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. Along with the anterior chamber and lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power. In humans, the refractive power of the cornea is approximately 43 dioptres. The cornea can be reshaped by surgical procedures such as LASIK. While the cornea contributes most of the eye's focusing power, its focus is fixed. Accommodation (the refocusing of light to better view near objects) is accomplished by changing the geometry of the lens. Medical terms related to the cornea often start with the prefix "'' kerat-''" from the Greek word κέρας, ''horn''. Structure The cornea has unmyelinated nerve endings sensitive to touch, temperature and chemicals; a touch of the cornea causes an involuntary reflex to close the eyelid. Because transparency is of prime importance, the healthy cornea does not have or need blood ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physical Trauma
An injury is any physiological damage to living tissue caused by immediate physical stress. An injury can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries. Treatment of a major injury is typically carried out by a health professional and varies greatly depending on the nature of the injury. Traffic collisions are the most common cause of accidental injury and injury-related death among humans. Injuries are distinct from chronic conditions, psychological trauma, infections, or medical procedures, though injury can be a contributing factor to any of these. Several major health organizations have established systems for the classification and description of human injuries. Occurrence Injuries may be intentional or unintentional. Intentional injuries may be acts of vio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basset Hound
The Basset Hound is a short-legged breed of dog in the hound family. The Basset is a scent hound that was originally bred for the purpose of hunting hare. Their sense of smell and ability to ''ground-scent'' is second only to the Bloodhound.Hart, Ernest H. ''This Is the Basset Hound'', T.F.H. Books, 1974. Basset Hounds are one of six recognized " basset"-type breeds in France. The name ''Basset'' is derived from the French word ''bas'', meaning 'low', with the attenuating suffix ''-et''—together meaning 'rather low'. Basset Hounds are usually bicolours or tricolours of standard hound coloration. Description Appearance Bassets are large, short, solid and long, with curved sabre tails held high over their long backs. An adult dog weighs between . This breed, relative to its size, is heavier-boned than any other. This breed, like its ancestor the Bloodhound, has a hanging skin structure, which causes the face to tend to have a sad look; this, for many people, adds to the ...

Bloodhound
The bloodhound is a large scent hound, originally bred for hunting deer, wild boar and, since the Middle Ages, for tracking people. Believed to be descended from hounds once kept at the Abbey of Saint-Hubert, Belgium, in French it is called, ''le chien de Saint-Hubert''. This breed is famed for its ability to discern human scent over great distances, even days later. Its extraordinarily keen sense of smell is combined with a strong and tenacious tracking instinct, producing the ideal scent hound, and it is used by police and law enforcement all over the world to track escaped prisoners, missing people, and lost pets. Appearance Bloodhounds weigh from 36 to 72 kg (80 to 160 lbs). They are 58 to 69 cm (23 to 27 inches) tall at the withers. According to the AKC standard for the breed, larger dogs are preferred by conformation judges. Acceptable colors for bloodhounds are black, liver, and red. Bloodhounds possess an unusually large skeletal structure wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Condition
A disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies and autoimmune disorders. In humans, ''disease'' is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, or death to the person affected, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structure a ...

Cocker Spaniel
Cocker Spaniels are dogs belonging to two breeds of the spaniel dog type: the American Cocker Spaniel and the English Cocker Spaniel of which are commonly called simply Cocker Spaniel in their countries of origin. In the early 20th century, Cocker Spaniels also included small hunting spaniels. Cocker Spaniels were originally bred as hunting dogs in the UK, with the term "cocker" deriving from their use to hunt the Eurasian woodcock. When the breed was brought to the United States, it was bred to a different standard, which enabled it to specialize in hunting the American woodcock. Further physical changes were bred into the cocker in the United States during the early part of the 20th century. Spaniels were first mentioned in the 14th century by Gaston III, Count of Foix in his work the ''Livre de Chasse''. The "cocking" or "cocker spaniel" was a type of field or land spaniel in the 19th century. Prior to 1901, Cocker Spaniels were only separated from Field Spaniels and Sprin ...
