AVMs are lesions of the vasculature that develop such that blood flows directly from the arterial system to the venous system without passing through a capillary system.

The clinical manifestations of Chagas disease are due to cell death in the target tissues that occurs during the infective cycle, by sequentially inducing an inflammatory response, cellular lesions, and fibrosis.

Two groups of rats are observed: a control group with no lesions and an experimental group with hippocampal lesions.

Diagnosis is done on a case by case basis, as lesions often affect surrounding cortex and deficits are not well conserved between patients.

Other causes of epilepsy are brain lesions, where there is scar tissue or another abnormal mass of tissue in an area of the brain.

The most common surgeries are the resection of lesions like tumors or arteriovenous malformations, which, in the process of treating the underlying lesion, often result in control of epileptic seizures caused by these lesions.

Other lesions are more subtle and feature epilepsy as the main or sole symptom.

Some sexually transmitted diseases are communicable between women, including human papillomavirus ( HPV )— specifically genital warts — squamous intraepithelial lesions, trichomoniasis, syphilis, and herpes simplex virus ( HSV ).

DNA polymerase η may help bypass these lesions in an error-free manner ; however, individuals with defective DNA repair function, such as sufferers of Xeroderma pigmentosum, are sensitive to sunlight and may be prone to skin cancer.

* CT scanning when mass lesions are suspected or to help diagnosis nephrolithiasis ;

Certain HPV types, in particular types 16 and 18, can also lead to progression from a benign wart to low or high-grade cervical dysplasia, which are reversible forms of precancerous lesions.

Quinolones are contraindicated if a patient has epilepsy, QT prolongation, pre-existing CNS lesions, CNS inflammation or suffered a stroke.

New lesions may appear for a few days after mites are eradicated.

The lesions are inflammatory, and involve the spinal cord typically on both sides.

The lesions can be present anywhere in the spinal cord, though they are usually restricted to only a small portion.

The three main conditions to be considered in the differential diagnosis are: acute spinal cord trauma, acute compressive lesions of the spinal cord such as epidural metastatic tumour, and infarction of the spinal cord, usually due to insufficiency of the anterior spinal artery.

Often, such bony lesions are absent and it is only the MRI or CT that discloses the presence or absence of a compressive lesion.

* In Langerhans cell histiocytosis, lesions initially are erythematous, purpuric papules and they then become scaly, crusted and sometimes confluent.

Named after physician Gerhard Armauer Hansen, leprosy is primarily a granulomatous disease of the peripheral nerves and mucosa of the upper respiratory tract ; skin lesions are the primary external sign.

Then, after the medical team has made sure they are on the right track, the tip of the electrode is advanced to the plane of the cingulate where it is heated to 75-90 C. Once the first lesion is created it serves as a center around which several other lesions are created.

In order to confirm whether lesions are made at the right place, images are taken postoperatively and analyzed.

Optic ataxia may be caused by lesions to the posterior parietal cortex.

Recovery may also be caused in very acute lesions by a return of blood flow and function to damaged tissue that has not died around an injured area.

It has also been seen that patients with aphasia caused by sub cortical lesions have a better chance of recovery than those with aphasia due to cortical stroke.

Many mutations arise as a result of problems caused by the DNA lesions during replication, resulting in errors in replication.

Characteristic evidence of the damage caused by PML in the brain can also be detected on MRI images, which classically show multifocal nonenhancing lesions without mass effect.

On funduscopic exam, a doctor will see cotton wool spots, flame hemorrhages ( similar lesions are also caused by the alpha-toxin of Clostridium novyi ), and dot-blot hemorrhages.

In 1981, researchers found that selective radio frequency lesions of the whole amygdala caused Klüver-Bucy Syndrome.

Specific types of micropsia include hemimicropsia, a form of micropsia that is localized to one hemisphere of the brain and can be caused by brain lesions.

A report on skin and soft tissue infections in the Cook County Jail in Chicago in 2004 – 05 demonstrated that MRSA was the most common cause of these infections among cultured lesions and furthermore that few risk factors were more strongly associated with MRSA infections than infections caused by methicillin-susceptible S. aureus.

Non-communicating hydrocephalus, or obstructive hydrocephalus, is caused by a CSF-flow obstruction ultimately preventing CSF from flowing into the subarachnoid space ( either due to external compression or intraventricular mass lesions ).

The term refers to a group of syndromes caused by different mechanisms all resulting in vascular lesions in the brain.

* Both lesions are caused by sexually transmissible organisms

Although trauma is a less common rhinoplastic occurrence, a nasal defect or deformity caused by blunt trauma ( impact ), penetrating trauma ( piercing ), and blast trauma ( blunt and penetrating ) requires a surgical reconstruction that abides the conservational principles of plastic surgery, as in the corrections of cancerous lesions.

With these criteria and environmental qualifiers ( e. g., 22 % of a 50-fish sample, all of the same species, have lesions caused by a toxin ), it is likely that Pfiesteria-related surveillance data can better track potential illnesses.

Another type of lesion is excitotoxic lesions that can be caused by excitatory amino acid like kainic acid that kills neuron by stimulating to death.

study ) will require antibiotic treatment for infection which is usually caused by bacteria from the skin or the baby's mouth that entering the milk ducts through skin lesions of the nipple or through the opening of the nipple.

* Both lesions are caused by sexually transmissible organisms

Granuloma inguinale is a bacterial disease caused by Klebsiella granulomatis characterized by ulcerative genital lesions.

Oral based lesions caused by viral infections like Herpes Simplex and HPV may also contribute to bad breath.

Common ailments affecting dairy cows include infectious disease ( e. g. mastitis, endometritis and digital dermatitis ), metabolic disease ( e. g. milk fever and ketosis ) and injuries caused by their environment ( e. g. hoof and hock lesions ).

It can be caused by a number of sources, including infections of the hoof tissue ( e. g. fungal infections that cause dermatitis ) and physical damage causing bruising or lesions ( e. g. ulcers or hemorrhage of the hoof ).

The dermatological symptoms of PCT that include blistering and lesions on sun-exposed areas of the skin are caused by a buildup of porphyrin compounds ( specifically uroporphyrinogen ) close to the surface of the skin.
