What is Perimysial inflammation?

Its name means “inflammation of many muscles” (poly- + myos- + -itis). The inflammation of polymyositis is mainly found in the endomysial layer of skeletal muscle, whereas dermatomyositis is characterized primarily by inflammation of the perimysial layer of skeletal muscles.

What are inflammatory myopathies?

What are the inflammatory myopathies? The inflammatory myopathies aare a group of diseases that involve chronic (long-standing) muscle inflammation, muscle weakness, and, in some cases, muscle pain. Myopathy is a general medical term used to describe a number of conditions affecting the muscles.

What is Perifascicular?

Perifascicular atrophy is the occurrence of small muscle fibers at the periphery of a fascicle that are atrophic with some fibers regenerating, and are thought to reflect ischemic changes secondary to disease of the vessels (6).

What are the symptoms of polymyositis?

Muscle pain and stiffness.
Muscle weakness, particularly in the belly (abdomen), shoulders, upper arms, and hips.
Joint pain and stiffness.
Trouble catching your breath.
Problems with swallowing.
Irregular heart rhythms, if the heart muscle becomes inflamed.

What are the signs and symptoms of Pyomyositis?

Pyomyositis is rare bacterial infection of the skeletal muscle (the muscles used for movement). Signs and symptoms may include pain and tenderness of the affected muscle, fever, and abscess formation. If left untreated, the abscess may extend into the bone and joint or blood poisoning may occur.

Is there an autoimmune disease that affects tendons?

When you have a connective tissue disease, these connecting structures are negatively affected. Connective tissue diseases include autoimmune diseases like rheumatoid arthritis, scleroderma and lupus.

Does dermatomyositis affect blood vessels?

In dermatomyositis, an abnormal immune reaction appears to lead to obstructive inflammatory changes of blood vessels within muscle, connective tissues of the skin, and other tissues; patchy degeneration, wasting (atrophy), and regeneration of muscle fibers; thinning of the outermost skin layer (epidermis); and/or other …

What organs are affected by polymyositis?

Polymyositis mostly affects the muscles of the hips and thighs, the upper arms, the top part of the back, the shoulder area and the neck.

What is the difference between polymyositis and polymyalgia?

Polymyositis is an inflammatory, destructive, autoimmune muscle disease, usually with weakness but unusually with pain. Polymyalgia rheumatica is an inflammatory disease of muscle that always causes symmetrically painful muscles. Polymyalgia rheumatica is not destructive to muscles.

What do you need to know about perihilar infiltrates?

Diseases Perihilar infiltrates is a condition in which any foreign substance gets stuck in perihilar region of lungs. Perihilar is the region which joins hilar I.e. roots of lungs with lungs. It consist of main pulmonary arteries and veins and main lung branch I.e. bronchi.

When do you use the term pulmonary infiltrate?

The term pulmonary infiltrate is considered a context-dependent, non-specific and imprecise descriptive term when used in radiology reports (plain film or CT).

What causes an external substance in the perihilar?

The external substance is an abnormal substance which can be virus, bacteria or fluids. Sometimes accumulation if growth tissue within perihilar can also cause perihilar infiltrate. Accumulating of fluids is the common cause of perihilar infiltrates. This condition closely resembles with pneumonia.

Can a virus cause a perihilar infiltrate in a child?

If the causative agent is a virus, then respiratory viruses are responsible. Viral perihilar infiltrates are not fatal, as they remain for short time and resolve on their own. It commonly occurs in older children and teenagers. Fluids accumulation in perihilar region leads to blockage of airways, as a result patient feel difficulty in breathing.
