Etiology



Tissue helminthiases, common in our country, are most often caused by helminth larvae belonging to different types and families: toxocariasis - by nematodes (roundworms) of the Anisakidae family: Toxocara canis, Toxocara mystax (s. T.catis); trichinella - nematode of the family Trichinellida Trichinella spiralis; ekhinokokokozyts and tstsertserkoz - cestodes (tapeworms) of the family Taeniidae: Echinococcus granulosus, E. multilocularis and Cysticercus cellulosae - the larva of pork tapeworm Taenia solium (respectively )

Etiology

  1. Etiology
    The etiological spectrum of pneumonia depends on the criteria for its diagnosis. Data on the predominance of viruses in the etiology of pneumonia are valid with extended diagnostic criteria. The leading role of viruses in the etiology of bronchiolitis, not accompanied by infiltrates or foci in the lungs, is proved by their successful treatment without antibiotics. Among lung lesions, accompanied by focal or infiltrative
  2. Etiology of granulomatosis.
    Distinguish between endogenous and exogenous etiological factors in the development of granulomas. Endogenous factors include insoluble products of damaged tissues, especially adipose tissue (soap), as well as products of impaired metabolism (urate). Exogenous factors causing the formation of granulomas include biological (bacteria, fungi, protozoa, helminths), organic and inorganic substances (dust,
  3. Etiology
    The etiology is unclear. Among the reasons that cause it, various authors tend to give priority to the following factors: - biomechanical; - developmental anomalies; - hormonal; - vascular; - infectious; - infectious and allergic; - functional; - hereditary. Osteochondrosis of the spine basically has local overload of the vertebral motor segments (PDS) and
  4. Etiology
    Infectious endocarditis is a polyetiological disease, the potential pathogens of which can be up to 128 varieties of microorganisms. The main ones are staphylococci (30-50%) and streptococci (20-30%). The increase in the etiological role of staphylococcus (usually golden) over the past 10-15 years is due to the widespread introduction of antibiotics into clinical practice, as well as
  5. ETIOLOGY
    The etiology of ulcerative colitis is not fully understood. Previously, they attached importance to microbial infection, viruses, fungi, as well as their associations. However, the microbial factor plays a role only in the formation of dysbiosis and in itself is insufficient for the development of the disease. At present, impairment of nonspecific resistance and immunological
  6. ETIOLOGY
    The cause of acute asphyxia is intranatal factors. However, the most severe course and prognosis is asphyxiation, which arose against a background of chronic antenatal hypoxia, which caused a violation of the normal maturation and functioning of all fetal systems. Mechanisms leading to acute asphyxia of the newborn 1) inadequate hemoperfusion of the maternal part of the placenta (hyper- or
  7. ETIOLOGY.
    According to current data, myocarditis can be associated with any infection. Almost all infectious diseases can be accompanied by myocarditis. Allocate: - infectious (diphtheria, scarlet fever, typhoid fever); - caused by a viral infection (most often influenza viruses, Coxsackie, polymyelitis, adenoviruses); - spirochitosis (syphilis, leptospirosis, relapsing fever); - parasitic
  8. Etiology
    The etiology of Parkinson's disease in the second half of 2011 is not fully understood. Etiological risk factors are aging, genetic predisposition, and environmental factors. Pathomorphologically normal aging is accompanied by a decrease in the number of neurons of the substantia nigra and the presence of Levi bodies in them. Aging is also accompanied by neurochemical changes in
  9. ETIOLOGY.
    All pleurisy is divided into infectious and non-infectious (aseptic), in which the inflammatory process in the pleura occurs without the direct participation of pathogenic microorganisms. An important cause of pleurisy is the causative agent of acute pneumonia and acute pulmonary suppuration: pneumococcus, staphylococcus, gram-negative bacilli, etc. Of great importance in the occurrence of pleurisy are mycobacterium tuberculosis.
  10. Etiology
    Irradiation - radiation leukemia, for example, radiologists are observed 10 times more often than people of other specialties. 2. Under the influence of medications: cytostatics: the incidence rate after their use increases by 100 times. Contrast media (used in coronary angiography, etc.). 3. Viral etiology - proven for leukemia of birds, rodents, but not convincing
  11. Etiology
    The causative agent of sepsis can be many microorganisms (table. 1). These are numerous bacteria: streptococci, staphylococci, meningococci, pneumococci, Escherichia coli, Pseudomonas aeruginosa, Klebsiella, Proteus, Salmonella, as well as mainly Candida and Aspergillus fungi. Sepsis can be complicated by the course of tuberculosis, typhus, typhoid fever and other infectious diseases,
  12. Etiology of Vitiligo
    The etiology and pathogenesis of the disease are complex and not completely established, and most often they are multifactorial in nature. The etiology of vitiligo is still not well understood and, in addition to the main classical theories of vitiligo, namely: melanocytic destruction (autoimmune, neurogenic), impaired redox status, impaired adhesion of melanocytes. According to autoimmune theory
  13. Etiology of Onychomycosis
    About 50 species of fungi can cause nail infections as the only pathogens. The etiology of these diseases becomes more diverse, given the cases of mixed infection, when several types of fungi are isolated from the affected nail. The role of many fungi as possible causative agents of onychomycosis has not yet been established. Known pathogens of onychomycosis are usually divided
  14. ETIOLOGY
    The etiology of pyelonephritis is the main bacterial factor. The non-bacterial nature of the disease is associated with viruses and mycoplasmas. The leading role in the occurrence of pyelonephritis belongs to autoinfection with a predominance of flora of the intestinal group, less often - pyogenic coccal flora from nearby or distant inflammatory foci. The most common pathogens are bacteria related to
  15. Etiology
    In 80% of all cases of acute pancreatitis, the cause is the cytotoxic effect of alcohol and the entry of bile into the pancreatic duct caused by bile stones. Ethanol is a more likely etiological factor in men, while bile stones are a more common cause of pancreatitis in women. TABLE 38.1 REASONS FOR ACUTE PANCREATITIS Common causes: Ethanol ~ 80% bile
  16. ETIOLOGY
    Determining the etiology of acute pneumonia is still a difficult problem to solve. In practical medicine, it is quite difficult to establish the true cause of the disease. Even the isolation of certain bacteria from the patient’s sputum does not mean that this particular microorganism is the culprit of the disease. To confirm the etiological role of the microbe found during microscopic examination
