Keutel syndrome

Keutel syndrome: A rare genetic syndrome characterized by narrowing of blood flow through the pulmonary artery, calcification of cartilage (such as in nose, ear, ribs) and short end bones on fingers and toes.

KID syndrome

KID syndrome: Acronym for the Keratitis- Ichthyosis-Deafness syndrome, a genetic disorder. Keratitis-ichthyosis-deafness syndrome: An inherited disorder in which affected persons have: * Keratitis -- gradual destruction of the cornea of the eye, sometimes leading to blindness * Ichthyosis -- localized areas of disfiguring reddish thickened skin ("fish skin") * Deafness -- at birth Another characteristic feature is thin or even absent scalp hair. Some patients have developed carcinoma of the tongue while others have subtle abnormalities of the nervous system. The KID syndrome is inherited as an autosomal dominant trait. The cause of the syndrome is mutation in the GJB2 (connexin 26) gene. The mutations in GJB2 involve one of the following amino acid substitutions: glycine replaced by arginine at position 12 (Gly12Arg), serine replaced by phenylalanine at position 17 (Ser17Phe), or aspartic acid replaced by tyrosine at position 50 (Asp50Tyr). The disease is also called the KID syndrome, an acronym for Keratitis-Ichthyosis-Deafness. Keratitis-ichthyosis-deafness syndrome, autosomal recessive: Another name for Ichthyosiform erythroderma, corneal involvement, deafness (or close medical condition association).

Klatskin tumor

A Klatskin tumor, also known as Hilar Cholangiocarcinoma, is a cholangiocarcinoma (cancer of the biliary tree) occurring at the confluence of the right and left hepatic bile ducts.

Klebsiella

Klebsiella: A genus of aerobic, facultatively anaerobic, nonmotile, non-spore-forming bacteria (family Enterobacteriaceae) containing gram-negative, encapsulated rods that occur singly, in pairs, or in short chains. These organisms produce acetylmethylcarbinol and lysine decarboxylase or ornithine decarboxylase. They do not usually liquefy gelatin. Citrate and glucose are ordinarily used as sole carbon sources. These organisms may or may not be pathogenic. They occur in the respiratory, intestinal, and urogenital tracts of humans as well as in soil, water, and grain. The type species is Klebsiella pneumoniae. [E. Klebs] Source: Stedman's Medical Spellchecker, © 2006 Lippincott Williams & Wilkins. All rights reserved. Klebsiella: genus of gram negative, facultatively anaerobic, rod shaped bacteria whose organisms arrange singly, in pairs, or short chains; this genus is commonly found in the intestinal tract and is an opportunistic pathogen that can give rise to bacteremia, pneumonia, urinary tract and several other types of human infection.

Kleeblattschaedel syndrome

Kleeblattschaedel syndrome: A very rare syndrome characterized mainly by a head the is somewhat cloverleaf shaped.

Kleefstra syndrome

A rare chromosomal disorder where the long arm (q) of chromosome 9 is deleted resulting in variable symptoms.

Kleine Levin Syndrome

Kleine-Levin Syndrome: A rare condition characterized by periods of excessive sleepiness (up to 20 hours a day), increased hunger, irritability and disorientation.

Kleiner Holmes syndrome

At a glance: Malformative syndrome characterized by the association of polysyndactyly and hallux valgus. Synomym: Hallux varus and Preaxial Polysysndactyly. Incidence and genetic inheritance: One case report of two siblings. Exact incidence unknown.Autosomal recessive inheritance. Clinical aspects: In 1980, Kleiner and Holmes described two brothers with bilateral hallux varus, One brother had duplication-triplication of the great toes and the other bad unusually broad great toes with Incomplete duplication of the phalanges. The parents were not related and showed no skeletal abnormality. Anesthetic considerations: No specific anesthetic considerations.

Klinefelter syndrome

Klinefelter syndrome is the set of symptoms that result from two or more X chromosome in males. The primary feature is sterility.

Klinefelter syndrome- variants

Klinefelter syndrome, variants: A genetic condition where males have at least one extra X chromosome or extra copies of both the X and Y chromosomes in each cell. Normally male cells contain one X and one Y chromosome in each cell. The condition is not inherited but is a result of problems during cell division.

Klippel Feil syndrome dominant type

Klippel-Feil syndrome, dominant type: A rare dominantly inherited disorder characterized by abnormal fusion of two or more vertebrae in the neck. The disorder is often associated with other abnormalities but their incidence is highly variable.

Klippel Feil syndrome recessive type

Klippel-Feil syndrome recessive type: A rare recessively inherited disorder characterized by abnormal fusion of two or more vertebrae in the neck. The disorder is often associated with other abnormalities but their incidence is highly variable.

Klippel Trenaunay syndrome

Nevus verucosus hypertrophicans Klippel-Trenaunay syndrome is a group of findings consisting of: * Multiple port wine stains or other blood vessel malformations, including dark spots of skin. * Excessive growth of bones and soft tissue. This occurs most commonly in the legs, but may affect the arms, the face, head, or internal organs. * Varicose veins that may be noted in early infancy. However, they are more likely to be seen later in childhood or adolescence. Bleeding from the rectum and blood in the urine may also occur.

Klumpke paralysis

Brachial palsy in newborns Alternative Names: Klumpke paralysis; Erb-Duchenne paralysis; Erb's palsy. Brachial palsy is a loss of movement or weakness of the arm caused by damage to the collection of nerves around the shoulder. This bundle of nerves is called the brachial plexus.

Kluver Bucy syndrome

  • Kluver-Bucy Syndrome: A condition where damage to the temporal brain lobes from any of a variety of causes (accident, hypoglycemia, Alzheimer's and others) results in symptoms such as memory loss and abnormal behavior.

  • Kluver-Bucy Syndrome: A neurobehavioral syndrome associated with bilateral medial temporal lobe dysfunction. Clinical manifestations include oral exploratory behavior; tactile exploratory behavior; hypersexuality; BULIMIA; MEMORY DISORDERS; placidity; and an inability to recognize objects or faces. This disorder may result from a variety of conditions, including CRANIOCEREBRAL TRAUMA; infections; ALZHEIMER DISEASE; PICK DISEASE OF THE BRAIN; and CEREBROVASCULAR DISORDERS.

Kniest dysplasia

Kniest dysplasia is one of several forms of dwarfism that is caused by a change (mutation) in a gene known as COL2A1. This gene is involved in the production of a particular protein that forms type 2 collagen, which is essential for the normal development of bones and other connective tissue. Changes in the composition of type 2 collagen lead to abnormal skeletal growth and, thus, to a variety of dwarfing conditions known as skeletal dysplasias.

Knobloch syndrome

Knobloch syndrome: A rare genetic syndrome characterized by detachment of the retina of the eye and an occipital encephalocele (protrusion of brain tissue through gap in skull at the back of the head).

Kohler disease

Synonyms of Kohler Disease

  • Kohler's Disease (of the Tarsal Navicular)
  • Kohler's Osteochondrosis of the Tarsal Navicular
  • Navicular Osteochondrosis

Kohler disease is a rare bone disorder of the foot in children that may be the result of stress-related compression at a critical time during the period of growth. It is characterized by limping caused by pain and swelling in the foot. It most often occurs in children between the ages of three and seven, and it affects males five times more often than it does females. Typically, just one foot is affected. Children appear to grow out of the disorder, and the affected bones regain their size, density and structure within a year. For some, however, symptoms may last as long as two years.

Kohlschutter Tonz syndrome

Kohlschutter-Tonz syndrome: A rare syndrome involving degeneration of the central nervous system, seizures and abnormal tooth development.
