Pollinosis in children is largely genetically determined by the key link in pathogenesis - increased synthesis of IgE. It has been proven that the ability to increased production of IgE is inherited in a recessive-dominant manner and is a necessary, but not the only condition for the formation of allergy to plant pollen.
Among allergens of biological origin, pollen occupies a prominent place. In humans, it causes an allergic disease called hay fever.
Poliomyelitis [from the Greek polio (gray), myelos (brain)] is an acute viral anthroponotic infectious disease with a fecal-oral mechanism of transmission of the pathogen, which is characterized by the predominant damage to the motor neurons of the spinal cord and brain with the development of paralysis.
According to WHO, snake venom poisoning is registered annually in 500,000 people, among them 6-8% of cases are fatal. The most severe poisoning occurs when a snake bites the head and neck or when the venom gets directly into the blood. When bitten by asps and sea snakes, there is often no pain, but within 20-30 minutes the condition sharply worsens, weakness develops, a feeling of numbness in the face and body, and collapse due to the release of histamine.
Of the 3,000 species of snakes in existence, only about 15% worldwide and 20% in the United States are dangerous to humans because they have venom or poisonous secretions.
Accidental poisonings and intentional self-inflicted (deliberate) poisonings are a common cause of emergency department visits and some deaths.
