Any woman who is pregnant will be very worried about her baby's Down syndrome. Now I'll share with you the symptoms of Down syndrome.
What are the symptoms of Down syndrome
First, Down's syndrome, also known as trisomy 21 syndrome or Down's syndrome, is a disease caused by chromosome abnormality (one more chromosome 21). 60% of the patients had abortion in the early intrauterine period. The survivors had obvious mental retardation, special face, growth and development disorder and multiple malformations.
Second, the child has obvious special facial signs, such as wide eye distance, low and flat nasal root, small eye fissure, oblique lateral eye, epicanthus, small external ear, fat tongue, often extending out of the mouth, salivation. Short stature, less than normal head circumference, short anterior and posterior head diameter, flat occipital head. The neck is short and the skin is loose. Bone age often lags behind age, and tooth emergence is delayed and often dislocated.
Third, the hair is soft and less. The anterior fontanel was closed late, and the third fontanel could be found in the midline of parietooccipital. The limbs are short. Due to the loose ligaments, the joints can be excessively bent. The fingers are thick and short. The middle segment bone of the little finger is dysplasia, which makes the little finger bend inward. The phalanges are short. The trigeminal point of the palm moves to the distal end. It is common to pass through the palmprint and the grass shoe foot. About half of the children have bow shaped dermatoglyphs at the bulb of the big toe.
matters needing attention
The prevention of Down's syndrome is very important. First of all, pregnant women should avoid electric radiation and chemical substances. In life, they should avoid electric radiation, try not to have X-ray examination, stay away from radioactive substances, and even watch TV for a long time. Women of childbearing age living in rural areas should do a good job in protecting all kinds of pesticides and some chemical substances to avoid direct contact.
