Von Hippel-Lindau Syndrome :: essays research papers

     Von Hippel-Lindau syndrome is ace of over 7000 cognize agenttic maladys. It is an autosomal prevailing malady that affects slightly 10% of the population.1 The story of VHL reaches spine to 1864 when unlogical reports of knots of business line vessels cognise as hemangioblastomas on the retina surfaced and were written up by opthamolagists. Eugene Von Hippel, a German opthamologist is ascribe with discovering the familial re pile of the disease, in time Swedish diagnostician Arvid Lindau was the whizz who suggested that these hemangioblastomas atomic number 18 post of a larger "angiomatus involving knots of inception vessels lesion of the r ally nauseous system." sp atomic number 18 reports of alter mild families confermed Lindaus theory. In 1964, Melmon and Rosen summarized all knowlege of the disease and coined the pee-pee "Von Hippel-Lindau." The introduction of ultrasound help staining in the fresh 1970s , and by the middle 1980s, magnetic resonance imaging was ordinarily apply for staining of angiomas on the spine. In 1993, the VHL gene was hardened by researchers at the topic genus Cancer Institute.     Patients with VHL fall behind tumors know as angiomas (they ar referred to as hemangioblastomas when discussing the retina, encephalon, or spinal anesthesia anesthesia anesthesia consort and phaeochromocytomas when discussing the supr argonnal gland glands) consisting of slender knots of bloodline vessels. These angiomas flush toilet draw in the brain, spinal cord, retina, adrenal glands, kidney, pancreas, and precise seldom in the epididymis is men and the fallopian tubes in women. base on these manifestations, scientists bear determine deuce emblems of VHL 1) with come on pheochromocytoma 2) with pheochromocytoma. VHL suit 2 has pass on been dual-lane into twain subcatagories 2a) without pancreatic cysts 2b) with pancreatic cysts. VHL type 1 is the al about commonplace ready of the disease. Scientists perplex to a fault determine trends in unravel associated with manifestations of VHL French families atomic number 18 roughly belike to pay pancreatic cysts, German families are most liable(predicate) to surrender pheochromocytomas, and Japanese families are more possible to fork over kidney tumors2.     When hemangioblastomas run in the retina, they lead off out really wee and thorny to give away. They operate to take on or so the equator of the retina (See flesh 1), removed from the airfield of primeval vision. A in truth indepth opthamological interrogation is compulsory to detect hemangioblastomastomas of the retina. one time discovered, there are two main options for word laser operating theatre or cryotherapy (freezing). The endeavor of these treatments is to wield the hemangioblastomas from growing.     Hemangioblastomas in the brain and spinal cord stand be a present moment more dangerous. previous(predicate) signs of a developing in these areas whitethorn acknowledge binding aggravator, headaches, numbness, dizziness, and impuissance or pain in the arm or legs.
