Children with congenital brain and skull deficiencies

Yes, the landlord said that he was brainless. You can encyclopedia brainless, if you have strong psychological endurance, you can directly click on the brainless **, let me remind you, it's a little scary, it looks really like a frog, don't look at it if you have weak psychological endurance. ps:

Encyclopedia also has a brainless **.

Introductions from elsewhere:

Anencephaly is a malformation that occurs in the early stages of the fetus. Anencephaly is a malformation in which the top of the baby's head and skull are not well developed, and most of the brain is not well developed. Anencephaly often dies in the mother's womb before the malformation, and although a few survive at birth, they usually die within a few days, and there are no cases of survival.

Causes: Genetic factors: Genetic diseases are diseases that can be passed on to future generations, and are diseases caused by harmful changes in the person's genetic material, including genetic mutations, chromosome number and structural abnormalities, the most common diseases are trisomy 21 and trisomy 18.

Environmental factors: including biological factors, chemical factors, physical factors and drug factors.

Biological factors: It is one of the more important causes of birth defects, especially when the mother is infected by certain pathogens during pregnancy (including viruses, bacteria, parasites, etc.), these pathogens can infect the fetus through the placental villous barrier or the cervix, mainly torch pathogen group, what is the doctor talking about torch? They are Toxoplasma, Rubella Virus, Cytomegalovirus, Herpes Simplex Virus, in addition to chickenpox, herpes zoster virus, hepatitis virus and Treponema pallidum, among others.

Chemical factors: pesticides such as dichlorfon, trichlorfon, organochlorine, organic mercury, oxyoxyacid herbicides, dibromochlorohydrin, dichloride, lead, cadmium, mercury, manganese, aluminum and other heavy metals and vinyl chloride, chloroprene, acrylonitrile and other polymer compounds.

Physical factors: Physical factors refer to the meteorological conditions, radiation noise and vibration that exist in people's daily life and production labor. Teratogenesis is mainly caused by radiation, such as X-rays and various other rays. Radiation can cause chromosomal aberrations that can cause malformations in the fetus.

Drug factors: Most antineoplastic drugs are toxic, and embryonic cells are more sensitive to antineoplastic drugs than mature and differentiated cells, so most of these drugs cause greater damage to the embryo at lower doses. Antibiotics such as streptomycin, kanamycin, most anti-tuberculosis drugs, hormones, and live vaccines are teratogenic when used in the first trimester, that is, during the teratogenic sensitive period.

Others: such as smoking, alcohol, the risk of fetal malformations after drinking a lot of alcohol is very high, which is characterized by developmental retardation, microcephaly, multiple small malformations, etc., smoking can cause miscarriage, premature birth, congenital heart disease and low birth weight of newborns.

It is recommended that you ask a doctor or look up on the medical network...

Yes A friend of mine was fighting in Vietnam, and the bullet passed through the top of his head and he didn't die.

The impact of the shot only hurt the skull? Dream unless you rub it against your scalp.

Flying by your scalp is a possibility.

Your child's skull and brain development have spinal lead mold problems, and at present, to find out the child's convulsive manifestations, whether an EEG examination has been done, first of all, to determine whether it is a seizure.
