Violations of the development of the fetus and the newborn are often developed with the endocrine maternal diseases, especially diabetes and diseases of the thyroid gland. Until then, until the placenta is formed as iron, secreted hormones of the endocrine glands are influenced by the fruit of similar glands of the mother. So,in the first weeks of pregnancy, fetal thyroid formed under the influence of thyroid hormones mother. When the placenta begins to throw its own hormones,fetus becomes less dependent.In this regard, it is important to women with different hormonal disorders get medical attention in the early stages of pregnancy for the treatment of affected organ.

In addition, a frequent cause of damage to fetus and newborn are infectious diseases the mother during pregnancy.Infection at a relatively early stage of pregnancy sometimes leads to fetal deformities incompatible with life. Infectious agents penetrate to the fetus most often through the placenta and affect it, and then, channeled through the fetal kidneys in the urine, are in the amniotic fluid. In result of ingestion of infected fruit waters, their contact with mucous shell develops a number of new infectious pathological processes, such as conjunctivitis, pneumonia, otitis media, intestinal lesions, etc. There is direct evidence that many viruses can easily penetrate to fetus through the placenta. These include viruses, rubella, enterovirus, cytomegalovirus, herpes virus, mumps, viral hepatitis and others particularly aggressive against the damaging effects on the fetus provides rubella virus. However, we must remember that a person been ill with rubella, the body creates immunity against the virus and its Contact a pregnant patient with rubella, usually not dangerous. When absence of immunity and disease of rubella in the first 3 months of pregnancy, when forming organs and systems of the fetus, fetal damage in the form of congenital heart defects, deafness and cataracts seen in almost 60 - 70% of cases. When disease of rubella in the later stages of pregnancy, fetal malformations usually does not occur.In case of contact with the patient pregnant, not bolevshey rubella, need to examine blood for antibodies to the virus, followed control over their level, and in addition, receive an injection of a specific immunoglobulin.
