Micropenis is the term used to describe the penis, the size of which is less than 2 standard deviations from the norm in the absence of any other visible pathology, accompanied by underdevelopment of the penis (eg, hypospadias, hermaphroditism).
Very close to the clinical manifestations of the linear migrating miase is the "migratory larva" (larva migrans), a skin disease caused by the larval of intestinal worms, most often by hookworm (Ancylistoma brasiliense, A. Ceylonicum, A. Caninum). All these parasites are the intestinal worms of animals, primarily dogs and cats.
Migraine status - more pronounced and prolonged in comparison with the usual attack of migraine symptoms. The development of migraine is due to a hereditary predisposition to inadequate regulation of the tone of the vessels of the brain (spasm and subsequent vasodilation) in response to the action of various factors of the external and internal environment.
Migraine is the most frequent diagnosis of headache, which is characterized by attacks of pulsating pain in the head lasting from several hours to several days, mostly in one half of the head, more often in women, as well as in young and adolescents.
Middle ear hemangiomas are characterized by the development of angiomatous formations from the vessels of the mucous membrane of the tympanic cavity and their spread to the surrounding tissues, accompanied by atrophy through pressure and various functional impairments.
Microtropy (monofixation syndrome) may be primary or occur in the outcome of surgery after removal of a large deviation angle.
Microsporia, a disease that affects the skin and hair, is more common in children. The causative agents of the microspores are classified by etiologic signs into anthropophiles, zoophiles and geophiles.
Microscopic polyarteritis - necrotizing vasculitis with small vessel damage associated with antineutrophil cytoplasmic autoantibodies (ANCA); It is common in many organs and systems, but the most pronounced changes are observed in the lungs, kidneys and skin. Isolated into a separate nosological form of systemic vasculitis in recent years and included in the 1992 classification.
Microscopic polyangiitis - necrotizing vasculitis with or without minimal immune deposits, affecting small vessels (arterioles, capillaries, venules), less often the arteries of the middle caliber, with a predominance in the clinical picture of necrotizing glomerulonephritis and pulmonary capillaritis.
The diagnosis of the microphthalmic is set when the length of the anterior-posterior axis of the eyeball is less than normal and corresponds to 21 mm in an adult and 19 mm in a one-year-old child.
Microcephaly is an extremely difficult incurable pathology, in which there is underdevelopment of the skull, insufficient functioning of the brain, dementia and other psychoneurological abnormalities.
In essence, the delimited forms of purulent peritonitis refer to extragenital foci of purulent inflammation. In patients with purulent formations of the uterine appendages, especially with a prolonged recurrent course, microperforations can occur during the next activation (exacerbation) of the process.
Mesadenitis is an inflammation of the lymph nodes of the mesentery and intestine. There are nonspecific (simple) and specific (tuberculous or pseudotuberculous) mesadenitis, which along the course is acute and recurrent.
Methylenedioxymethamphetamine (MDMA - commonly known as ecstasy, or Adam, or "E") is an analogue of amphetamine. MDMA is usually used in the form of pills. It has both stimulating and hallucinogenic properties. Long-term use can cause dependence.
One of the main functions of the endometrium is the provision of implantation and embryo nidation. An important role in this process is played by the maturity of the endometrium, its synchronization with the hormonal background during the menstrual cycle.
Methemoglobin, in contrast to conventional hemoglobin, contains unreduced iron (Fe2 +), and oxidized (Fe3 +) and in the process of reversible oxygenation, oxyhemoglobin (HbO2) is partially oxidized to methaemoglobin (Mt Hb).
This is a very dangerous substance that acts quickly enough and leads to serious consequences, disability and even death.
Meteorological cheilitis is a disease caused by the influence of meteorological factors (high or low humidity, dustiness of the air, wind, cold).
Metatypical skin cancer (syn: basal cancers, mixed cancers, intermediate carcinoma) can develop on unchanged skin, but often occurs against a pre-existing basal cell, especially after X-ray therapy. The clinical manifestations of metatypeic cancer in most cases do not differ from the clinical picture of basal cell and usually correspond to its tumor and ulcerated forms.
