hypoplasia of the thyroid gland in children - a congenital disease caused by a deficiency of iodine in the body of a pregnant woman or a hereditary deficiency of enzymes involved in the synthesis of thyroid hormones.It is important to identify this disease right after birth.
main function of the thyroid gland
The main function of the thyroid is the formation and release into the blood and lymph hormones that regulate metabolism improves metabolism and losing weight without dieting in cells and thus regulatethe processes of growth, development and differentiation (acquisition of cell properties specific to a particular tissue) tissues.
thyroid cells absorb and accumulate iodine, and then synthesized from the amino acid tyrosine, and a thyroid hormone - thyroxine Thyroxine - the main thyroid hormone (T4) and triiodothyronine (T3).The human body does not produce iodine, so for the proper functioning it must regularly deal with food and water.Regulates the secretion of thyroid horm
With a lack of iodine in a person develops symptoms of deficiency of thyroid hormone - hypothyroidism.Most suffer from iodine deficiency, pregnant women: this may affect the development of the thyroid gland in the fetus, that is, cause it to hypoplasia or aplasia.
symptoms of thyroid hypoplasia in the newborn
hypoplasia of the thyroid gland - is a congenital anomaly of the prostate, which is accompanied by insufficient development of breast tissue anddecrease its function.Hypoplasia develops in the womb because of a shortage of iodine in her body.
deficiency of thyroid hormones in the blood leads to the rapid development of significant breaches in the body of the child, especially if a significant hypoplasia.
suspect the presence of hypoplasia of the thyroid gland in the newborn child can be the case if the child is lethargic, sleeps a lot and not breastfeeding, she had no reaction to bright objects and loud sounds.A sign of thyroid hypoplasia can also be prolonged physiological jaundice and chronic constipation.
further development of hypoplastic thyroid baby
depends on the degree of underdevelopment and manifests mostly lag in the physical and psychological development.Such children have a poor appetite, constant lethargy and sleepiness, almost does not develop, or it develops very slowly, there is hoarseness.
goes wrong development of the musculoskeletal system: long bones shorter, dense, long-term growth areas are not closed.The skull has a peculiar form, deformed downward.Parietal and frontal bones thicken.
Appearance baby is very characteristic: short stature, short limbs, bulging belly, big head, puffy face, broad nose, open mouth (tongue may be increased in size) and a meaningless expression.
Children suffering hypoplasia hypoplasia - a congenital malformation of the fetus thyroid, have a peculiar character: they are closed, unsociable, sluggish, unsociable.Sometimes these children are flashes of aggressiveness or bouts of depression Depression - a little more than a bad mood , but they do not stay long, if others are child-friendly.Psychological development can vary from small disturbances (mild retardation) to significant changes and even a complete idiot.
Mild hypoplasia of the thyroid symptoms of the disease can be lethargy and lack of alertness of the child, combined with a slight increase, clumsy movements, and some delays in speech development.
fetal thyroid hypoplasia rarely detected during pregnancy.Therefore, all newborns taken blood test for thyroid stimulating hormone - TSH.When hypoplasia thyroid function it will be reduced, i.e. in the blood will be little hormones T3 and T4.The amount of TSH is always elevated.
Child, which revealed a large blood levels of TSH, a fully examined: carried ultrasound of the thyroid gland, bone age X-ray of the child and determine the level of thyroid hormones and TSH levels.
If the diagnosis of hypoplasia of the thyroid gland was installed on time and assign adequate treatment (replacement thyroid hormone therapy), the irreversible changes in the brain tissue can be avoided and the child is developing according to its age.
