Methotrexate is a medication used to treat cancers, autoimmune diseases like rheumatoid arthritis, and skin conditions like psoriasis and atopic dermatitis. It slows the growth of rapidly dividing cells, such as cancer cells, and reduces inflammation in autoimmune disorders. Administered orally or by injection, it requires regular monitoring due to potential side effects like liver damage and bone marrow suppression.

MRSA is an acronym that stands for "methicillin-resistant staphylococcus aureus". So it is a bacterium called Staphylococcus aureus that is resistant to the antibiotic methicillin.

MPV is an acronym for "mean platelet volume". It refers to the average volume or size of platelets. This test is routinely performed as part of a hemogram or complete blood count examination.

Monocytes are cells that are located in the blood. They belong to leukocytes or white blood cells. They are part of the immune system. Monocytes from the blood migrate to tissues, where they transform into macrophages. The essential task of macrophages is the "swallowing" of microorganisms or dead cells, but they also have other functions within the immune response.

It is a viral skin infection, in which tiny warts (usually the color of the skin) appear on the skin, caused by the mollusc virus. Molluscs are a common infection in children with atopic dermatitis. In adult patients, however, it can also be a sexually transmitted infection.

It is a viral skin infection, where small warts (usually the color of the skin) appear on the skin, caused by the molluscum virus. Mehkužke are a common infection in children with atopic dermatitis. In adult patients, however, it can also be a sexually transmitted infection.

The methacholine test is a diagnostic examination used to detect asthma, especially when symptoms are mild or irregular. Methacholine is a substance that causes narrowing of the airways (bronchospasm) in people with asthma, but not in healthy individuals. The test is performed by having a person inhale increasing amounts of methacholine. After each inhalation, it is measured how much air a person can exhale at once. If the amount of air a person can exhale is reduced by a certain percentage, the test is positive for asthma.

MEF is an acronym for "maximal expiratory flow". It refers to the maximum air flow during exhalation. MEF is measured in liters per second. The measurement is carried out during spirometry.

MCV is an acronym found in the results of lab. blood tests. MCV stands for "mean corpuscular volume". It refers to the average volume of red blood cells or erythrocytes. MCV is important when we want to determine the type of anemia (anemia - a decrease in the amount of hemoglobin and/or the number of red blood cells). In microcytic anemia (e.g., iron deficiency), the MCV is decreased, while in macrocytic anemia (e.g., vitamin B12 deficiency), the MCV is increased.

MCHC is an acronym that we find in the lab. blood test results. MCHC stands for "mean corpuscular hemoglobin concentration". It refers to the amount of hemoglobin per specific volume unit (e.g. g/dcl).
