Lesions

Identify the physiological origins of the following skin lesions TELANGIETASIA These are typically known as broken capillaries. They can also be known as... Naevus flammeus, Klippel-Trenaunay syndrome, Maffucci's syndrome, Hereditary hemorrhagic, Telangiectasia, Ataxi-telangiectasia. Telangiectasia are tiny blood vessels on the surface of the skin that are permanently dilated they appear bright red or sometimes appear as a dull red. These appear like small red likes and may even look like tree

Introduction Traumatic brain injuries are one of the leading causes for damage in the brain and lesions (TBI) (Wheeler, Nickerson, Long & Silver, 2014). Two types of injuries that occur following brain damage are open and closed head injuries. Open head injuries are often fatal and occur in such cases as when objects such as bullets penetrate the head of the victim. Closed head injuries result from blows to the head in situations such as car accidents or sports injuries. TBIs normally evolve in two

The neuroanatomical approach to aphasia relies on the localization of lesions on the brain in addition to clinical observation in order to classify patients according to syndromes. For example, according to the neuroanatomical approach, Broca’s aphasia, which us usually associated with a lesions on the posterior inferior frontal gyrus of the brain, has cardinal features that distinguish is from other fluent and non-fluent aphasias (e.g. poor repetition, poor repetition and poor naming with good auditory

nervous system to the muscle fibers; from the brainstem to the cranial nerves with motor function, or from the anterior horns of grey matter to the spinal nerves (Murdoch, 1998). If there are lesions to spinal nerves and the cranial nerves with motor speech functions, it is indicative of a lower motor neuron lesion and flaccid dysarthria. Damage to lower motor neurons that supply the speech

• Streptococcus pneumoniae, (cause pneumonia, and upper lobe lesions) • Klebsiella pneumoniae,(cause pneumonia, cause destructive changes to lungs, leading to rise the respiratory rate) • Haemophilus influenzae, (cause pneumonia, opportunistic with alcoholism can lead to enlarge the liver) • Moraxella catarrhalis, (cause pneumonia, pathogen with an affinity for the human upper respiratory tract) • Staphylococcus aureus, (cause pneumonia, it usually affect patient with chronic illness) • Legionella

learned to dissect the fragile structures of the eye by inventing new methods that involved sectioning the eye after it had been fixed by heating in egg whites. Discovering the lesions of the atherosclerosis and their possible role in obstruction of the coronary arteries. Even more remarkably, he presciently attributed these lesion to an “overabundance of nourishment” from the blood. The

atrophy. Now a days , cortical lesions and brain atrophy have emerged as new pathological markers of MS Progression. GM damage was first reported by Sander in 19th century . About 26% lesions are found in cortical and subcortical GM. In a study by Dalton et al, no WM loss and increasing GM loss was seen in patients with developing MS over 3 years following a CIS. The immunohistochemical staining techniques differentiates 4 major categories of cortical lesions: 1) lesion involves deeper layer of GM and

Lesion segmentation methods can be applied to different regions of the body. Lipková et al. (2017), used an unsupervised segmentation algorithm to find liver lesions in computed tomography (CT) scans. Researchers in this study agree that manual and semi-automated methods are impractical “with an intra- and interobserver variability up to 11 % in volume difference on liver CT scans” (p. 1). Furthermore, they oppose supervised methods because “a significant variation in lesions shape and

Treatment of lymphoma may cause fibrosis and necrosis in lymph nodes which can limit size-based response assessments. In 1999, the IWG criteria commonly known as Cheson criteria, defined five categories of clinical response based on CT imaging of lesion size for non-Hodgkin Lymphoma (NHL) [36]. Original criteria had limitations such as a high variability, the failure to consider 18FDG-PET, immunohistochemistry (IHC) and flow cytometry and the failure to take into account non-nodal disease. Revised

Fig:Transverse sonography image shows well circumscribed hypoechoic, oval shaped mass without any suspicious characteristics, suggesting probably benign lesion (BIRADS category 3) in a 32-year-old woman with palpable breast mass. It was confirmed as fibroadenoma on sonography-guided core biopsy (Kim et al, 2008). Ultrasound BIRADS 3 lesions are difficult to manage because of their uncertain nature. Although they are likely to be benign, there is still a low possibility of malignancy. And thus they
