When mesenchymal dysproteinosis in the connective tissue of the dermis and the walls of the blood vessels, protein metabolism is disrupted. At the same time, metabolic products accumulate, which can come with blood or lymph, or are formed as a result of improper synthesis or disorganization of the main substance of the dermis and its fibrous substances.
Mesangioproliferative glomerulonephritis is characterized by the proliferation of mesangial cells, the expansion of mesangium, the deposition of immune complexes in mesangium and under the endothelium.
Mesangiocapillary (membranoproliferative) glomerulonephritis - a variant of glomerulonephritis with a progressive course is very rare.
MERRF syndrome (Myoclonic Epilepsy with Ragged-Red Fibers, myoclonus-epilepsy, "torn" red fibers) was first described in 1980. Later, the disease was allocated to an independent nosology.
Mental retardation is a condition caused by congenital or early acquired underdevelopment of the psyche with a pronounced lack of intelligence, which makes it difficult or completely impossible for an adequate social functioning of the individual.

The upper surface of the meniscus is concave, and the lower surface is almost flat.

Meningococcal infection is an acute infectious disease with clinical manifestations from nasopharyngitis and asymptomatic carriage to generalized forms - purulent meningitis, meningoencephalitis and meningo-coccemia with the defeat of various organs and systems.
Meningococcal infection is an acute anthroponous infectious disease with an aerosol mechanism of transmission of the pathogen, which is characterized by fever, intoxication, hemorrhagic rash and purulent inflammation of the brain membranes.
Meningocele is a type of pathological condition that refers to anterior cerebral hernia caused by congenital deficiency of bone tissue in the bottom of the anterior cranial fossa during embryonic development under the influence of certain external (infection) and internal (genetic) causes, resulting in a delay in the closure of the protero-vertebral brain plates

Meningitis is an inflammation of the membranes of the brain or spinal cord. Often the disease is infectious in nature and is one of the most common infectious diseases of the central nervous system.

In rare cases, meningitis develops without fever, which greatly complicates the diagnosis and may indicate disorders of the immune system. 

The main pathogens of purulent meningitis in newborns and children - streptococcus group B or D, Escherichia coli, Listeria monocytogenes, Haemophilus influenzae, in adults - pneumococci, staphylococcus, etc. Risk factors include immunodeficiency, craniocerebral trauma, surgery on the head and neck .
