In residency programs,... Prion Infections Infection without inflammation – Prion diseases A. PathogenesisHuman spongiform encephalopathies are a group of disorders that share certain clinical, pathological, and pathogenetic features. All cause a progressive, fatal, dementing illness; most... Alzheimer Disease Alzheimer's Disease is the most common dementing illness and can occur at any age over 30. It tends to affect women more than men, even when survival differences are taken into account. It is relatively uncommon before age 65, affecting about 0.1% of the... Vascular Disease 4: Other topics in vascular disease Working from the outside in, intracranial hemorrhage may be epidural, subdural, subarachnoid, intraparechymal, or intraventricular in origin (though many do not remain localized to a single compartment). The term “hemorrhagic stroke” only applies to subarachnoid and intraparenchymal hemorrhages... GFAP Glial fibrillary acidic protein (GFAP) is the major intermediate filament expressed in astrocytes and ependyma. Immunohistochemical staining with antibodies specific for GFAP consequently highlights these cells. In the examples here, the regions which stain brown indicate the presence of GFAP... H&E - Normal Example (image) Commonly used stains In this section, we'll go over some of the more commonly used stains in neuropathology. Different stains might be used in different tissues. For example, the Gomorri trichrome stain is especially helpful in muscle to find certain types of myopathy... Other Immune Stains Immunohistochemical (IHC) staining is the technique of using antibodies against a specific antigen (such as amyloid, CD68, ubiquitin, or GFAP) to label a tissue. This technique is extremely versatile, since it can be applied to virtually any epitope to which a specific antibody can be created... Electron Microscopy In pathology-speak, Electron Miscroscopy is often referred to as EM or ultrastructural examination.EM is time consuming and technically challenging, but allows the visualization of structures much, much smaller than anything visible on light miscoscopy. ... COX (Cytochrome Oxidase) Staining Cytochrome oxidase (cox) is an oxidative enzyme in the electron transport chain. Staining for cox is a sensitive method to assess capacity for oxidative metabolism. Type I muscle fibers have a higher capacity for oxidative metabolism than type II cells,... NADH NADH is a marker for oxidative activity. Histochemical staining for NADH can therefore give an indication of the relative oxitadive activity of a structure. Among other things, NDAH staining can be used to differentiate Type I from Type II mucle fibers, or show the presence of central cores. ATPase ATPase stains are histochemical stains to assess the relative function of myofibrillar ATPase. This is helpful in distinguishing Type I fibers from Type II fibers.ATPase stains differently depending on the pH at which the stain is performed. At lower pH values (e... H & E H&E is short for Hematoxylin and Eosin. The H&E staining method is the most commonly used stain in neuropathology. It is a simple stain, and provides an excellent first look at the tissue of interest.Hematoxylin as a basic dye, and has an affinity for basophilic structures... H&E Stain of a Pilocytic Astrocytoma (image) Other non-immune stains These stains are ones that you may come across during your rotation or during your reading, but are less frequently used than the ones discussed elsewhere.These are all tinctorial stains, not immune or histochemical stains.Click any of the images below for... Myopathy with Tubular Aggregates Tubular aggregates are a fairly nonspecific finding. They are found in many muscle disorders, including perioric paralyses, some myotonic disorders, ond some toxic myopathies. Tubular aggreagates look like this (click to enlarge): References:Katirji, B...

They are often apparent at birth, but may not manifest symptoms until later in life. Categorization of Congenital Myopathies Since there is considerable overlap in... Multicore Disease / Minicore Disease Multicore Disease and Minicore Disease are synonymous terms.The disorder they describe is related to, but distinct from, central core disease. In central core disease, the mitochondria-lacking cores run the whole length of the muscle fiber. In minicore...

Pilocytic Astrocytoma Pilocytic astrocytomas are less common than diffuse astrocytomas, accounting for about 2% of all primary CNS tumors in all age groups. However, they are the most common glioma in children.They frequently occur in the cerebellum, but can occur in other areas as well... Ependymomas Ependymomas are classified as glial tumors, although they also have epithelial properties. They are common, accounting for 3%-9% of all brain tumors. They can occur at any age, but are somewhat more common in children.40% of ependymomas occur in the first decade of life...
