Leukoplakia - leukokeratosis, manifested as milky-white spots on the mucous membranes covered with multilayered flat epithelium (oral cavity, vagina, red lip rim), develops as a result of local irritant factors, as well as inflammatory phenomena.
Leukoplakia is a chronic disease of the mucous membrane of the mouth and lips, resulting from an exogenous stimulus, and characterized by keratinization of the mucous membrane. It occurs on all continents. Men are sick 2 times more often than women, at the age of 40-70 years.
Leukoplakia is a pathological process, the basis of which is the disturbance of the function of multilayered planar epithelium: the absence of glycogenesis and the appearance of keratinization (hyperkeratosis).
Simple leukoplakia refers to dyskeratosis diseases - that is, to those that are accompanied by impaired keratinization. Pathology affects stratified squamous epithelial tissue and can be found in the oral cavity, respiratory tract, urogenital tract, and the anal area.
Leukopenia or neutropenia is a syndrome in which the absolute number of circulating neutrophils in the blood is below 1.5x109 / L The extreme manifestation of neutropenia is agranulocytosis, a condition in which the number of granulocytes in the blood is below 0.5x109 / l.
Leukoderma - like leukocytes, leukemia and plaster - the term of Greek etiology, and leukos means "white". Although, you will agree, if you do not know what is the essence of leukoderma, then the name of this skin disease (according to the consonance with blood cancer - leukemia) looks ominous.
Leukemia is a malignant tumor of leukocyte germ, involving the pathological process of bone marrow, circulating leukocytes and organs, for example the spleen and lymph nodes.
Skin leukemids (synonyms: skin leukemia, hemoderma) are symptoms of leukemia and manifest in its terminal stage. However, sometimes skin signs are the initial symptoms of leukemia, when other symptoms (changes in blood, lymph nodes and bone marrow) are still absent.
Leukemia is a common name for malignant tumors originating from the hematopoietic cells, which account for about 1/3 of all oncological morbidity in children. Oncological morbidity (leukemia, lymphomas and solid tumors) in Russia is about 15 cases per year per 10,000 children and adolescents, which in absolute figures is more than 15,000 children newly infected per year.
Leukocyturia is an indicator of the presence of an inflammatory process in the urinary tract, renal pelvis and kidney tissues.
Damage to the larynx is one of the most life-threatening injuries, which, if not lead to death, is most often doomed to permanent cannulation, disability and a significant deterioration in the quality of life.
Multi-form exudative erythema of Gerbera is a rare itchy dermatosis, manifested by strongly itchy papules that rise above the surface of the skin, which is an acute cyclical disease characterized by a sudden symmetrical rash on the skin of the extensor surfaces of the extremities.
Anthrax is an acute infectious disease, zoonotic caused by an anthrax wand that occurs with skin, lymph nodes and internal organs. The skin form of anthrax in most cases is manifested with the formation of a specific carbuncle.
The eye can also be involved in the process with other common viral diseases; in particular chicken pox, measles, and rubella.
Wegener's granulomatosis is a severe general disease from the group of systemic vasculitides. Which is characterized by granulomatous lesions, in the first place, the upper respiratory tract, lungs and kidneys.
Epidemiology of Leszmann's syndrome. Population frequency is unknown. Not more than 1% of patients with deep mental retardation exhibit a 5p- deletion.
The disease is an infectious parasitic disease of the mucous membrane of the pharynx, which proceeds in the form of acute pharyngitis or sore throat with a defeat of the palatine tonsils.
Leptospirosis - an acute infectious disease, related to zovozam. It is characterized by a primary lesion of liver, kidney, cardiovascular, nervous system and eye.
Leptospirosis is widespread on all continents. At the end of XIX century. German physician A. Weyl (1886) and Russian researcher N.P. Vasiliev (1889) reported a special form of infectious jaundice, which occurs with liver, kidney and hemorrhagic syndrome.
Leptospirosis (Vasiliev-Weil disease, infectious jaundice, Japanese 7-day fever, nannukai, water fever, ikterogemorragicheskaya fever, etc.) - a general term for all infections caused by bacteria of the genus Leptospira regardless of the serotype; includes infectious, or leptospiroznuyu, jaundice and canine fever.
