The diagnosis is made by the clinical picture and the chest X-ray, which demonstrates decreased lung volumes (bell-shaped chest), absence of the thymus (after about six hours), a small (0.5–1 mm), discrete, uniform infiltrate (sometimes described as a "ground glass" appearance or "diffuse airspace and interstitial opacities") that involves ...
Primary familial brain calcification [1] (PFBC), also known as familial idiopathic basal ganglia calcification (FIBGC) and Fahr's disease, [1] is a rare, [2] genetically dominant or recessive, inherited neurological disorder characterized by abnormal deposits of calcium in areas of the brain that control movement.
With the brain, this process happens early in development, again during puberty, and pregnancy probably reflects another wave of cortical refinement.” Increase in brain white matter during pregnancy
Hypoxia refers to deficiency of oxygen, Ischemia refers to restriction in blood flow to the brain. The result is “encephalopathy” which refers to damaged brain cells. Encephalopathy is a nonspecific response of the brain to injury which may occur via multiple methods, but is commonly caused by birth asphyxia, leading to cerebral hypoxia. [2 ...
High-resolution CT image showing ground-glass opacities in the periphery of both lungs in a patient with COVID-19 (red arrows). The adjacent normal lung tissue with lower attenuation appears as darker areas. Ground-glass opacity (GGO) is a finding seen on chest x-ray (radiograph) or computed tomography (CT) imaging of the lungs.
The underlying cause may be a dysfunctional molecular mechanism in the primary cilia structures of the cell organelles that are present in many cellular types throughout the human body. The cilia defects adversely affect "numerous critical developmental signaling pathways" essential to cellular development and thus offer a plausible hypothesis ...
Around the foci is generally defined area of other lesions of the brain white matter - the death of prooligodendrocytes, proliferation mikrogliocytes and astrocytes, swelling, bleeding, loss of capillaries, and others (the so-called "diffuse component PVL"). However, diffuse lesions without necrosis are not PVL.
The symptoms of a TIA typically resolve within 24 hours, unlike a stroke. Brain injury may still occur in a TIA lasting only a few minutes. Having a TIA is a risk factor for eventually having a stroke. [10] [11] Silent stroke is a stroke which does not have any outward symptoms, and the patient is typically unaware they have had a stroke.
