Perineal Hernia
Perineal hernia is a hernia involving the perineum (pelvic floor). The hernia may contain fluid, fat, any part of the intestine, the rectum, or the bladder. It is known to occur in humans, dogs, and other mammals, and often appears as a sudden swelling to one side (sometimes both sides) of the anus. A common cause of perineal hernia is surgery involving the perineum. Perineal hernia can be caused also by excessive straining to defecate. Other causes include prostate or urinary disease, constipation, anal sac disease (in dogs), and diarrhea. Atrophy of the levator ani muscle and disease of the pudendal nerve may also contribute to a perineal hernia. In humans In humans, a major cause of perineal hernia is perineal surgery without adequate reconstruction. In some cases, particularly surgeries to remove the coccyx and distal sacrum, adequate reconstruction is very difficult to achieve. The posterior perineum is a preferred point of access for surgery in the pelvic cavity, parti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hernia
A hernia is the abnormal exit of tissue or an organ (anatomy), organ, such as the bowel, through the wall of the cavity in which it normally resides. Various types of hernias can occur, most commonly involving the abdomen, and specifically the groin. Groin hernias are most commonly of the inguinal hernia, inguinal type but may also be femoral hernia, femoral. Other types of hernias include Hiatal hernia, hiatus, incisional hernia, incisional, and umbilical hernias. Symptoms are present in about 66% of people with groin hernias. This may include pain or discomfort in the lower abdomen, especially with coughing, exercise, or Urination, urinating or Defecation, defecating. Often, it gets worse throughout the day and improves when lying down. A bulge may appear at the site of hernia, that becomes larger when bending down. Groin hernias occur more often on the right than left side. The main concern is Strangulation (bowel), bowel strangulation, where the blood supply to part of the bowe ...

Rectal Prolapse
A rectal prolapse occurs when walls of the rectum have prolapsed to such a degree that they protrude out of the anus and are visible outside the body. However, most researchers agree that there are 3 to 5 different types of rectal prolapse, depending on whether the prolapsed section is visible externally, and whether the full or only partial thickness of the rectal wall is involved. Rectal prolapse may occur without any symptoms, but depending upon the nature of the prolapse there may be rectal discharge, mucous discharge (mucus coming from the anus), rectal bleeding, degrees of fecal incontinence and obstructed defecation symptoms. Rectal prolapse is generally more common in elderly women, although it may occur at any age and in either sex. It is very rarely life-threatening, but the symptoms can be debilitating if left untreated. Most external prolapse cases can be treated successfully, often with a surgical procedure. Internal prolapses are traditionally harder to treat and sur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boston Terrier
The Boston Terrier is a breed of dog originating in the United States of America. This "American Gentleman" was accepted in 1893 by the American Kennel Club as a non-sporting breed. Color and markings are important when distinguishing this breed from the AKC standard. They should be either black, brindle or seal with white markings. Boston Terriers are small and compact with a short tail and erect ears. The AKC says they are highly intelligent and very easily trained. They are friendly and can be stubborn at times. The average life span of a Boston Terrier is around 11 to 13 years. The American Kennel Club ranked the Boston Terrier as the 21st most popular breed in 2019. History The Boston terrier breed originated around 1875, when Robert C. Hooper of Boston purchased from Edward Burnett a dog named Judge (known later as Hooper's Judge), which was of a bull and terrier type lineage. Hooper's Judge is directly related to the original bull and terrier breeds of the 19th and earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Kelpie
The Australian Kelpie, or simply Kelpie, is an Australian sheepdog capable of mustering and droving with little or no guidance. It is a medium-sized dog and comes in a variety of colours. The Kelpie has been exported throughout the world and is used to muster livestock, primarily sheep, cattle and goats. The breed has been separated into two distinct varieties: the Show (or Bench) Kelpie and the Working Kelpie. The Show Kelpie is seen at conformation dog shows in some countries and is selected for appearance rather than working instinct, while the Working Kelpie is bred for working ability rather than appearance. History The ancestors of most Kelpies were British dogs known loosely as collies (sometimes spelled colleys). These were mostly black, or very dark brown, dogs – hence the name collie, which has the same root as coal. (The official collie breeds were not formed until about 10 or 15 years after the Kelpie was established as a breed, and the first recognised Borde ...

Boxer (dog)
The Boxer is a medium to large, short-haired dog breed of mastiff-type, developed in Germany. The coat is smooth and tight-fitting; colors are fawn, brindled, or white, with or without white markings. Boxers are brachycephalic (they have broad, short skulls), have a square muzzle, mandibular prognathism (an underbite), very strong jaws, and a powerful bite ideal for hanging on to large prey. The Boxer was bred from the Old English Bulldog and the now extinct Bullenbeisser, which became extinct by crossbreeding rather than by a decadence of the breed. The Boxer is a member of both The Kennel Club and American Kennel Club (AKC) Working Group.http://www.akc.org/dog-breeds/boxer/#standard "Get to Know the Boxer", 'The American Kennel Club', Retrieved 14 May 2014 The first Boxer club was founded in 1895, with Boxers being first exhibited in a dog show for St. Bernards in Munich the next year. Based on 2013 AKC statistics, Boxers held steady as the seventh-most popular breed of dog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Welsh Corgi
The Welsh Corgi ( or Corgi, plural Corgis, or occasionally the etymologically consistent Corgwn; ) is a small type of herding dog that originated in Wales. The name ''corgi'' is derived from the Welsh words and (which is mutated to ), meaning "dwarf" and "dog", respectively. Two separate breeds are recognized: the Pembroke Welsh Corgi and the Cardigan Welsh Corgi. Physical differences are seen between the two breeds. According to the breed standards, overall the Cardigan is larger, both in weight and height. Their tails are of different shapes, and docking was previously performed on Corgis before the practice was largely banned. Historically, the Pembroke has been attributed to the influx of dogs alongside Flemish weavers from around the 10th century, while the Cardigan is attributed to the dogs brought with Norse settlers, in particular a common ancestor of the Swedish Vallhund. The Pembroke is the more popular of the two, yet still appears on the Kennel Club's vulner ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neutering
Neutering, from the Latin ''neuter'' ('of neither sex'), is the removal of an animal's reproductive organ, either all of it or a considerably large part. The male-specific term is castration, while spaying is usually reserved for female animals. Colloquially, both terms are often referred to as fixing. In male horses, castrating is referred to as ''gelding''. An animal that has not been neutered is sometimes referred to as ''entire'' or ''intact''. Neutering is the most common method for animal sterilization. Humane societies, animal shelters, and rescue groups urge pet owners to have their pets neutered to prevent the births of unwanted litters, which contribute to the overpopulation of unwanted animals in the rescue system. Many countries require that all adopted cats and dogs be sterilized before going to their new homes. Methods of sterilization Females (spaying) Spaying is the surgical removal of the ovaries and uterus in female animals. It is commonly performed as a ...

Gluteus Maximus
The gluteus maximus is the main extensor muscle of the hip. It is the largest and outermost of the three gluteal muscles and makes up a large part of the shape and appearance of each side of the hips. It is the single largest muscle in the human body. Its thick fleshy mass, in a quadrilateral shape, forms the prominence of the buttocks. The other gluteal muscles are the medius and minimus, and sometimes informally these are collectively referred to as the glutes. Its large size is one of the most characteristic features of the muscular system in humans,Norman Eizenberg et al., ''General Anatomy: Principles and Applications'' (2008), p. 17. connected as it is with the power of maintaining the trunk in the erect posture. Other primates have much flatter hips and cannot sustain standing erectly. The muscle is made up of muscle fascicles lying parallel with one another, and are collected together into larger bundles separated by fibrous septa. Structure The gluteus maximus is the ...

Orthopedic
Orthopedic surgery or orthopedics ( alternatively spelt orthopaedics), is the branch of surgery concerned with conditions involving the musculoskeletal system. Orthopedic surgeons use both surgical and nonsurgical means to treat musculoskeletal trauma, spine diseases, sports injuries, degenerative diseases, infections, tumors, and congenital disorders. Etymology Nicholas Andry coined the word in French as ', derived from the Ancient Greek words ὀρθός ''orthos'' ("correct", "straight") and παιδίον ''paidion'' ("child"), and published ''Orthopedie'' (translated as ''Orthopædia: Or the Art of Correcting and Preventing Deformities in Children'') in 1741. The word was assimilated into English as ''orthopædics''; the ligature ''æ'' was common in that era for ''ae'' in Greek- and Latin-based words. As the name implies, the discipline was initially developed with attention to children, but the correction of spinal and bone deformities in all stages of life eventually ...

Coccygectomy
Coccygectomy is a surgical procedure in which the coccyx or tailbone is removed. It is considered a required treatment for sacrococcygeal teratoma and other germ cell tumors arising from the coccyx. Coccygectomy is the treatment of last resort for coccydynia (coccyx pain) which has failed to respond to nonsurgical treatment. Non surgical treatments include use of seat cushions, external or internal manipulation and massage of the coccyx and the attached muscles, medications given by local injections under fluoroscopic guidance, and medications by mouth. To remove the coccyx, an incision is made from the tip of the coccyx to its joint with the sacrum. The coccyx is cut away from the surrounding tissues, cut off at the joint with the sacrum, and removed. If the tip of the sacrum is rough, it is filed down. The wound is closed in layers.An improved technic of coccygectomy. Clinical Orthopedics, 85: 143-145, 1972. Richard C Gardner. http://www.coccyx.org/medabs/gardner.htmPrevention o ...

Sacrococcygeal Teratoma
Sacrococcygeal teratoma (SCT) is a type of tumor known as a teratoma that develops at the base of the coccyx (tailbone) and is thought to be primarily derived from remnants of the primitive streak. Sacrococcygeal teratomas are benign 75% of the time, malignant 12% of the time, and the remainder are considered "immature teratomas" that share benign and malignant features. Benign sacrococcygeal teratomas are more likely to develop in younger children who are less than 5 months old, and older children are more likely to develop malignant sacrococcygeal teratomas. The Currarino syndrome, due to an autosomal dominant mutation in the MNX1 gene, consists of a presacral mass (usually a mature teratoma or anterior meningocele), anorectal malformation and sacral dysgenesis. Presentation Complications Maternal complications of pregnancy may include mirror syndrome. Maternal complications of delivery may include a Cesarean section or, alternatively, a vaginal delivery with mechanical dyst ...
