	Lesion - Wikipedia, the free encyclopedia
		A lesion is a non-specific term referring to abnormal tissue in the body.
		Lesions can also be inflicted intentionally during surgery, for example to specific regions of the brain to treat epilepsy.
		Lesion is derived from a Latin word which means "injury."

	American Lesion - Wikipedia, the free encyclopedia
		American Lesion is a solo album by Greg Graffin, lead singer of the punk band, Bad Religion.
		American Lesion for the most part features Graffin's voice alone, and each song is based around a piano rather than a guitar.
		The songs on American Lesion are much more personal; the songs were apparently written during the breakup of his marriage, making the album very sentimental.

	BERC Publications: The Nature of a Fatal DNA Lesion (Site not responding. Last check: 2007-10-22)
		All that is required to predict the probability a cell survives a dose of radiation is a model to estimate the distribution of fatal lesions produced among a group of irradiated cells.
		Then once the distribution of fatal lesions in a group of cells has been determined, the number of cells surviving irradiation is easily computed because all cells with one or more fatal lesions in their DNA die.
		To formalize the relationship between fatal lesions and cell survival, a fatal lesion is the minimum amount of some type of DNA damage (or the expected number of mutations) required to kill, in the reproductive sense, a cell.

	Lesion...What Does The Doctor Mean? - Cancer information on MedicineNet.com
		A benign lesion is non-cancerous whereas a malignant lesion is cancerous.
		For example, a biopsy of a skin lesion may prove it to be benign or malignant, or evolving into a malignant lesion (called a premalignant lesion).
		For instance, a Ghon lesion (or Ghon focus) is the scar-like "signature" in the lungs of adults left by tuberculosis in childhood.

	Skin lesion removal
		Lesions that are confined to the surface may be sampled with a shave biopsy, where the physician holds a scalpel blade parallel to the surface of the skin and slides the blade across the base of the lesion, removing a sample.
		If a lesion is suspected to be cancerous, the physician will not cut directly around the lesion, but will attempt to also remove a healthy margin of tissue surrounding it.
		It is typically sprayed on the lesion in several freeze-thaw cycles to ensure adequate destruction of the lesion.

		The fidelity of lesion repair tends to increase as the polarity increases.
		Lesions composed of a single EDS have a EDS density of zero.
		The fidelity of lesion repair thus tends to increase as the density decreases.

		The lesion was hairless, measuring 0.5 cm in diameter, with a slightly denuded appearance and a rolled edge (Figure 2).
		Lesions with findings such as vascular flushing, tethering (which may be a sign of a dural attachment), or abnormal surrounding hair may signal further abnormalities and warrant evaluation.
		Lesions typically are hairless and yellowish and often occur on the scalp or face.

	Bundling of Lesion Excision and Repair Procedures
		If multiple distinct lesions are removed using different methods, an anatomic modifier or the 59 modifier would be used to indicate a different site, a different method, or a different lesion.
		A lesion biopsy represents the partial removal of a lesion and is frequently performed as a part of a lesion excision, in order for example, to procure a pathological specimen.
		When a biopsy is performed as part of a lesion removal, it is considered inherent to the overall procedure and is not reported separately.

	Fact Sheet: Nodules, Polyps, and Cysts
		Vocal cord lesions are one of the most common causes of voice problems and are generally seen in three forms; nodules, polyps, and cysts.
		This type of lesion is thought to develop from trauma or repeated injury caused by the lesion on the opposite vocal cord.
		Lesions are thought to arise following "heavy" or traumatic use of the voice, including voice misuse such as speaking in an improper pitch, speaking excessively, screaming or yelling, or using the voice excessively while sick.

	lesion - multiple sclerosis encyclopaedia (Site not responding. Last check: 2007-10-22)
		In multiple sclerosis, lesions, also known as plaques, are patches of inflammation in the central nervous system (CNS) in which the nerve cells (neurons) have been stripped of their myelin, an insulating fatty protein.
		Lesions tend to be randomly distributed in the CNS white matter.
		Recent research indicates that there may be at least four different types of lesion indicating four different forms of multiple sclerosis or even that MS is in fact four different diseases.

	Epilepsy and Lesionectomy
		A lesionectomy is an operation to remove a lesion -- a damaged or abnormally functioning area -- in the brain.
		A lesion causes seizures (is the seizure focus) in about 20% to 30% of people with epilepsy that do not improve after taking medication (intractable or refractory epilepsy).
		In addition, it must be possible to remove the lesion and surrounding brain tissue without causing damage to areas of the brain responsible for vital functions, such as movement, sensation, language and memory.

	Will just removing the lesion stop my seizures? : Epilepsy.com
		For lesions in the temporal lobe, this means that your surgery will be more like a temporal lobectomy, the most common kind of epilepsy surgery for people who do not have visible lesions.
		If your lesion is close to the hippocampus or if your seizures began when you were very young, it's likely that an examination would show that many cells have been lost.
		If the lesion is in the dominant temporal lobe, subdural grid electrodes may be used to record seizures and map regions of language function.

		Stener described a lesion of the UCL in which the distal attachment was traumatically avulsed from the proximal phalanx of the thumb.
		With a Stener lesion, a situation exists in which the MCP joint of the thumb is rendered permanently unstable because the UCL is prevented from healing by the interposed adductor aponeurosis.

	Skin Lesion Biopsy - Page 3
		Used to remove an entire lesion when the lesion is small, or when the lesion is large but is located in an area of the body where it can be removed without affecting the patient’s appearance.
		Sometimes, lesions are removed by a process called curettage, during which a lesion is scraped off with a scoop–shaped instrument called a curet.
		Lesions filled with fluid may be examined during a separate process called a skin lesion aspiration.

	Skin Lesion Recognition
		Primary lesions occur de novo in the skin and often reflect the underlying etiology.
		It must be kept in mind that lesions in skin disease may undergo a sequential evolution, resulting in a variety of identifiable changes in the skin, that when observed together can assist in deducing the underlying pathologic changes, and formulating a differential diagnosis.
		These are often regarded as secondary lesions, but can be thought of as ruptured, peripherally spreading pustules, vesicles or bullae, giving rise to the appearance of a ring of scale.

	Lesion reconstruction notes
		The general idea is that the lesions are traced onto a standard template image of the brain.
		With this package, the user draws the lesion on the patient's actual MRI or CT scan, and then the image is automatically normalized (coregistered) to a template brain that includes overlays of the Damasio and Damasio Brodmann Area overlays.
		Note that a posterior lesion has been mapped onto the template image, and that the lesion can also be displayed on the Brodmann Area map.

		Herpes viral culture of a lesion is a test to confirm the presence of herpes simplex virusÂ in a skin sore.
		A specimen from a skin lesion (often a genital sore) is collected during the acute phase (worst part) ofÂ an outbreak and placed in a special substance called medium.
		The specimen may be placed in cell cultures, so they can replicate to helpÂ identification, or it may be identified by monoclonal antibodies that detect early antigens of herpes simplex virus.

		The data suggest that within an individual, the lesion pattern is the same, but between individuals, it can be very different.
		In active lesions of these individuals, a specific myelin protein called MAG (myelin-associated glycoprotein) was more likely to be lost, with other myelin proteins being well preserved.
		The team is preparing to report findings about individuals with one pattern of lesion who showed findings on MRI that were distinct from other individuals.
