	Telangiectasia - Wikipedia, the free encyclopedia
		Telangiectasias, or spider veins, are small enlarged blood vessels near the surface of the skin; usually they measure only a few millimeters.
		Telangiectasias can result in nevus flammeus (port-wine stain), which is a flat birthmark on the head or neck that spontaneously regresses.
		Finally, spider telangiectasias are a radial array of tiny arterioles that commonly occur in pregnant women and in patients with hepatic cirrhosis.

	Ataxia telangiectasia - Wikipedia, the free encyclopedia
		AT is characterized by progressive cerebellar ataxia, oculocutaneous telangiectasia, progressive cerebellar dysfunction, and recurrent sinopulmonary infections secondary to progressive immunological and neurological dysfunction (Boder, 1958).
		Telangiectasias are not seen in the early stages of the disease and begin to appear after a few years i.e.
		Oculo-cutaneous telangiectasia is often not obvious in the early stages of the disease.

	Telangiectasia
		Telangiectasias are abnormally dilated blood vessels associated with a number of diseases.
		Telangiectasias may develop anywhere within the body but can be easily seen in the skin, mucous membranes, and whites of the eyes.
		Telangiectasias may also occur in the brain and cause major problems from bleeding.

	Hereditary hemorrhagic telangiectasia - Genetics Home Reference
		Juvenile polyposis/hereditary hemorrhagic telangiectasia syndrome is a condition that involves both arteriovenous malformations and a tendency to develop growths (polyps) in the gastrointestinal tract.
		Mutations in the ACVRL1, ENG, and SMAD4 genes cause hereditary hemorrhagic telangiectasia.
		Juvenile polyposis/hereditary hemorrhagic telangiectasia syndrome is caused by mutations in the gene SMAD4.

	Hereditary Hemorrhagic Telangiectasia \| Principal Health News
		Hereditary hemorrhagic telangiectasia is an inherited condition characterized by abnormal blood vessels which are delicate and prone to bleeding.
		The term telangiectasia refers to a spot formed, usually on the skin, by a dilated capillary or terminal artery.
		Unlike hemophilia, where bleeding is caused by an ineffective clotting mechanism in the blood, bleeding in hereditary hemorrhagic telangiectasia is caused by fragile blood vessels.

	Telangiectasia macularis eruptiva perstans
		COMMENT: Telangiectasia macularis eruptiva perstans is a rare form of cutaneous mastocytosis and is observed in less than one percent of the patients with mastocytosis.[1,2] It is a disorder affecting adults and has been reported in one child.[3] Clinically, there are tan-to-brown macules and patchy erythema with telangiectases that most often involve the trunk.
		However, unilateral facial telangiectasia macularis eruptiva perstans has been reported.[4] Most patients only have cutaneous involvement with pruritus of variable degree.[5] Systemic involvement is rare but can include episodic headaches, flushing, gastrointestinal complaints, palpitations, syncope, splenomegaly, increased numbers of mast cells in the bone marrow, and abnormal skeletal radiographs.
		There is a report of temporary treatment of telangiectasia macularis eruptiva perstans with the 585 nm flashlamp-pumped dye laser.[6] It is also important to pretreat with proper H1 and H2 receptor blockers to avoid potential complications from laser-induced mediator release.

		Telangiectasias are a second major clinical manifestation (nonneurologic) of the disease.
		Ocular telangiectasias may be mistaken for conjunctivitis, but they can be readily distinguished because they are dilated vessels against a white background, whereas the background is pink in conjunctivitis.
		Pigmentary changes were frequent, occurring in a mottled pattern of hyperpigmentation and hypopigmentation with cutaneous atrophy and telangiectasia, similar to the poikiloderma seen in scleroderma, advanced actinodermatitis, or radiodermatitis, and in premature aging.

	Ataxia Telangiectasia: Fact Sheet - National Cancer Institute
		Ataxia telangiectasia (A-T) is a primary immunodeficiency disease which affects a number of different organs in the body.
		Telangiectasias (tiny, red "spider" veins), which appear in the corners of the eyes or on the surface of the ears and cheeks, are characteristic of the disease, but are not always present and generally do not appear in the first years of life.
		The cloning and sequencing of the gene (named ATM, for ataxia telangiectasia, mutated) has opened several avenues of research to develop better treatment, including: (1) gene therapy; (2) the design of drugs to correct the function of the altered protein; and (3) direct replacement of the functional protein.

		In cells from ataxia telangiectasia patients, due to their lack of active ATM kinase, an increase in chromosomal aberrations and a failure to induce G(2) lengthening could be expected.
		The differential response to caffeine of ataxia telangiectasia and control lymphocytes may be explained by the presence of two different subpathways in the G(2) checkpoint: one regulating the processing and repair of damaged DNA and the other controlling G(2) timing.
		Confirmation of this model in ataxia telangiectasia cells with another cell type in which both subpathways are mediated by DNA-PK should define whether a metylxanthine such as caffeine may also have an additional direct inhibitory effect on DNA repair.

	Ataxia Telangiectasia
		In addition, telangiectasias may develop by mid-childhood, often appearing on sun-exposed areas of the skin, such as the bridge of the nose, the ears, and certain regions of the extremities, as well as the mucous membranes of the eyes (conjunctiva).
		Ataxia Telangiectasia is inherited as an autosomal recessive trait.
		However, in individuals with Ataxia Telangiectasia, abnormal changes (mutations) of the ATM gene cause an absence or defect of the ATM protein and delayed accumulation of the p53 protein.

		In medicine, hereditary hemorrhagic teleangiectasia (HHT), also known as Rendu-Osler-Weber syndrome, is a genetic disorder that leads to vascular malformations.
		HHT is characterised by telangiectasia (small vascular malformations) on the skin and mucosal linings, epistaxis (nosebleeds), and arteriovenous malformation s (AVMs) in various internal organs.
		Skin and mucosa telangiectasias are most remarkable on the tongue, hands/fingers, nose, lips, mouth/throat and conjunctiva.

	Hemorrhagic Telangiectasia, Hereditary
		Hereditary hemorrhagic telangiectasia type I is caused by a gene on chromosome 9 and is probably associated with a greater frequency of pulmonary arteriovenous malformations.
		Hereditary hemorrhagic telangiectasia type II is caused by a gene on chromosome 12 and has been proven to be associated with symptoms and manifestations similar to those seen with HHT type I. A third type of HHT is suspected, but no gene has been identified.
		A diagnosis of hereditary hemorrhagic telangiectasia is made based upon a detailed patient history, a thorough clinical evaluation, and identification of characteristic findings.

	Telangiectasia (Red Spots on Skin)
		Scleroderma can cause telangiectasia on the face and/or hands, and the presence of telangiectasia on the face and/or hands counts as one of the criteria for diagnosing CREST Syndrome.
		Telangiectasia frequently appear on the trunk and extremities of healthy people and so although you may have them there also, those telangiectasia do not count towards a CREST diagnosis.
		However, "Second Generation" Telangiectasia (ones that return after the first treatment) are often resistant to treatments, and I highly recommend that you (and your dermatologist) read about that situation before starting any course of treatment for telangiectasia.

		We must emphasize that no sourcebook on ataxia telangiectasia should affirm that a specific diagnostic procedure or treatment discussed in a research study, patent, or doctoral dissertation is “correct” or your child’s best option.
		When their child has been diagnosed with ataxia telangiectasia, parents will often log on to the Internet, type words into a search engine, and receive several Web site listings which are mostly irrelevant or redundant.
		Because of this, far less research is conducted on ataxia telangiectasia compared to other health problems afflicting larger populations, like breast cancer or heart disease.

		Symptoms Ataxia telangiectasia presents in childhood at the age of about 2 with a progressive cerebellar ataxia which is present in all cases.
		Signs Telangiectasia develop at a later stage than the ataxia, and may not be present until the age of 10, but once again will be present in all cases.
		Differential Diagnosis Ataxia telangiectasia can be distinguished from other hereditary ataxia such as Friedrich’s ataxia by an earlier age of onset, the presence of telangiectasia and the development of dystonia and chorea later on.

		The kinetics of p53 response was intermediate between normal and classical ataxia telangiectasia cells in both the 7271T-->G and 5762ins137 cells, but interestingly, c-Jun kinase activation following DNA damage was equally deficient in cell lines derived from all the ataxia telangiectasia patients.
		RESULTS: Comparing the pattern of short repeats in the Thy-1 gene sequences of Turkish patients with ataxia telangiectasia (AT) with the "wild type" sequence from the DNA database, we identified a missing 8-bp repeat element due to an SNP in position 1271 (intron II) in AT-DNA sequences.
