Clinical InformationClinical

  • Hyaline Fibromatosis Syndrome

    autosomal recessive disorder characterized by hyaline deposition in the skin, bone, gastrointestinal tract, muscles and glands; multiple subcutaneous skin nodules; gingival hypertrophy; and joint contractures. mutations in the capillary morphogenesis protein-2 are associated with the disorder.

  • Pseudoxanthoma Elasticum

    an inherited disorder of connective tissue with extensive degeneration and calcification of elastic tissue primarily in the skin, eye, and vasculature. at least two forms exist, autosomal recessive and autosomal dominant. this disorder is caused by mutations of one of the atp-binding cassette transporters. patients are predisposed to myocardial infarction and gastrointestinal hemorrhage.

  • Necrobiotic Xanthogranuloma

    a cutaneous necrobiotic disorder characterized by firm, yellow plaques or nodules, often in a periorbital distribution. it is often accompanied by an elevated erythrocyte sedimentation rate; leukopenia; and monoclonal gammopathy (igg-kappa type) and systemic involvement.

  • Arterio-Arterial Fistula

    abnormal communication between two arteries that may result from injury or occur as a congenital abnormality.

  • Arteriovenous Fistula

    an abnormal direct communication between an artery and a vein without passing through the capillaries. an a-v fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. the locations and size of the shunts determine the degree of effects on the cardiovascular functions such as blood pressure and heart rate.

  • Biliary Fistula

    abnormal passage in any organ of the biliary tract or between biliary organs and other organs.

  • Bronchial Fistula

    an abnormal passage or communication between a bronchus and another part of the body.

  • Carotid-Cavernous Sinus Fistula

    an acquired or spontaneous abnormality in which there is communication between cavernous sinus, a venous structure, and the carotid arteries. it is often associated with head trauma, specifically basilar skull fractures (skull fracture, basilar). clinical signs often include vision disorders and intracranial hypertension.

  • Cassia

    a plant genus of the family fabaceae. many species of this genus, including the medicinal c. senna and c. angustifolia, have been reclassified into the senna genus (senna plant) and some to chamaecrista.

  • Cutaneous Fistula

    an abnormal passage or communication leading from an internal organ to the surface of the body.

  • Dental Fistula

    an abnormal passage in the oral cavity on the gingiva.

  • Digestive System Fistula

    an abnormal passage communicating between any components of the digestive system, or between any part of the digestive system and surrounding organ(s).

  • Esophageal Fistula

    abnormal passage communicating with the esophagus. the most common type is tracheoesophageal fistula between the esophagus and the trachea.

  • Fistula

    abnormal communication most commonly seen between two internal organs, or between an internal organ and the surface of the body.

  • Gastric Fistula

    abnormal passage communicating with the stomach.

  • Intestinal Fistula

    an abnormal anatomical passage between the intestine, and another segment of the intestine or other organs. external intestinal fistula is connected to the skin (enterocutaneous fistula). internal intestinal fistula can be connected to a number of organs, such as stomach (gastrocolic fistula), the biliary tract (cholecystoduodenal fistula), or the urinary bladder of the urinary tract (colovesical fistula). risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (medical errors).

  • Oral Fistula

    an abnormal passage within the mouth communicating between two or more anatomical structures.

  • Oroantral Fistula

    a fistula between the maxillary sinus and the oral cavity.

  • Pancreatic Fistula

    abnormal passage communicating with the pancreas.

  • Rectovaginal Fistula

    an abnormal anatomical passage between the rectum and the vagina.

  • Respiratory Tract Fistula

    an abnormal passage communicating between any component of the respiratory tract or between any part of the respiratory system and surrounding organs.

  • Salivary Gland Fistula

    a fistula between a salivary duct or gland and the cutaneous surface of the oral cavity.

  • Tracheoesophageal Fistula

    abnormal passage between the esophagus and the trachea, acquired or congenital, often associated with esophageal atresia.

  • Urinary Bladder Fistula

    an abnormal passage in the urinary bladder or between the bladder and any surrounding organ.

  • Urinary Fistula

    an abnormal passage in any part of the urinary tract between itself or with other organs.

  • Vaginal Fistula

    an abnormal anatomical passage that connects the vagina to other organs, such as the bladder (vesicovaginal fistula) or the rectum (rectovaginal fistula).

  • Vascular Fistula

    an abnormal passage between two or more blood vessels, between arteries; veins; or between an artery and a vein.

  • Vesicovaginal Fistula

    an abnormal anatomical passage between the urinary bladder and the vagina.

  • Arteries

    the vessels carrying blood away from the heart.

  • Stomach

    an organ of digestion situated in the left upper quadrant of the abdomen between the termination of the esophagus and the beginning of the duodenum.

  • Pancreas

    a nodular organ in the abdomen that contains a mixture of endocrine glands and exocrine glands. the small endocrine portion consists of the islets of langerhans secreting a number of hormones into the blood stream. the large exocrine portion (exocrine pancreas) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the duodenum.

  • Rectum

    the distal segment of the large intestine, between the sigmoid colon and the anal canal.

  • Urinary Bladder

    a musculomembranous sac along the urinary tract. urine flows from the kidneys into the bladder via the ureters (ureter), and is held there until urination.

  • Urinary Tract

    the duct which coveys urine from the pelvis of the kidney through the ureters, bladder, and urethra.

  • ABCC6 wt Allele|ABC34|ARA|ATP-Binding Cassette, Sub-Family C (CFTR/MRP), Member 6 wt Allele|ATP-Binding Cassette, Subfamily C, Member 6 Gene|EST349056|GACI2|MLP1|MOAT-E|MOATE|MRP6|PXE|PXE1|Pseudoxanthoma Elasticum Gene|URG7

    human abcc6 wild-type allele is located in the vicinity of 16p13.1 and is approximately 75 kb in length. this allele, which encodes multidrug resistance-associated protein 6, plays a role in the active transport of drugs across the plasma membrane. mutation of the gene is associated with pseudoxanthoma elasticum and generalized arterial calcification of infancy type 2.

  • Pseudoxanthoma Elasticum

    a rare, progressive, autosomal recessive inherited disorder caused by mutations in the abcc6 gene. it is characterized by calcification and fragmentation of the elastic fibers of the skin, retina, and cardiovascular system. signs and symptoms include skin plaques and bumps, thickened skin, retinal hemorrhage and obstruction of the blood vessels.

  • Spastic Paraplegia 56|Autosomal Recessive Spastic Paraplegia-56 with or without Pseudoxanthoma Elasticum|SPG56

    an autosomal recessive subtype of hereditary spastic paraplegia caused by mutation(s) in the cyp2u1 gene, encoding cytochrome p450 2u1.

  • Skin Eschar

    a crust that covers necrotic tissue in the skin that is caused by a burn or gangrene.

  • Stiff Skin Syndrome

    a rare, autosomal dominant inherited syndrome caused by mutations in the fbn1 gene. it is characterized by hard and thickened skin, usually over the entire body, and limited joint motility.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
