The delay in speech development, abbreviated as RRDS, represents a later mastery of oral speech skills by children under 3 years of age compared to the average age norm. The delay in speech development can be qualitative or quantitative, it is expressed in the insufficient development of the vocabulary and in the lack of expressive conversation, and may also be the absence of phrasal speech in a child of 2 years. If the baby does not speak coherently and more or less understandably by the age of 3, his speech development is delayed.
Children with a delay in speech development must necessarily be consulted by a pediatric neurologist and pediatric otolaryngologist, as well as a speech therapist and psychologist. However, the latter is not necessary and is done only by necessity. In some cases, a medical examination and diagnosis are necessary. Further, corrective work is carried out aimed at eliminating the delay in speech development. This must necessarily include psychological and pedagogical, and if necessary, medical assistance.

Unvaccinated children 2-9 years old are most often affected. Rubella is especially dangerous in the first 3 months of pregnancy – in this case, severe congenital malformations of the child often develop, intrauterine death of the fetus is possible. In general, rubella is more severe in adults than in children.
The source of infection is a person with a clinically expressed or worn-out form of rubella. Routes of transmission – airborne (in conversation with the patient, kisses) and vertical (from mother to fetus). A contact route of infection is also possible – through children’s toys. The patient becomes contagious 1 week before the rash appears and continues to secrete the virus for 5-7 days after the rash appears. A child with congenital rubella excretes the pathogen for a longer time (up to 21-20 months).
The incubation period of the disease lasts from 11 to 24 days (usually 16-20). Continue reading
Nature took great care of man, making it possible to make up for the deficiency of nutrients from food, the environment, and water. However, people did not appreciate this gift. Pollution of air, water, production of non-natural products led to various unpleasant consequences. One of them was iodine deficiency. Why is this trace element needed? And what are the consequences of its lack?
Why does a person need iodine
Iodine is a water soluble trace element. It is found in many foods (in shrimp, seaweed). They are rich in sea air and water. In the human body, iodine is responsible for the proper functioning of the thyroid gland. Thanks to this microelement, the most important hormones are synthesized – thyroxine and triiodothyronine. They provide the correct course of metabolism, cell division, heat transfer in the body and many other functions.
If we talk about iodine, then it participates in the following functions:
stimulation of metabolic processes; Continue reading
