It is still not known what causes anencephaly. It is probably triggered by a combination of genetic and environmental factors. We nevertheless know that taking Folic Acid can prevent anencephaly. Some medicines (the pill, valproic acid, antimetabolic drugs and others) lower Folic Acid levels, hence taking them increases the risk of giving birth to a child with anencephaly.

Spina bifida and anencephaly are birth defects that occur in the first four weeks of pregnancy, before most women know that they are pregnant. Because about half of all pregnancies are unplanned, it is important to include 400 micrograms of folic acid in every childbearing age woman's diet. Spina bifida occurs when the lower end of the neural tube fails to close. Thus, the spinal cord and back bones do not develop properly.

Anencephaly is a fatal condition in which the upper end of the neural tube fails to close. In these cases, the brain either never completely develops or is totally absent. Pregnancies affected by anencephaly often result in miscarriages. Infants who are born alive die very soonafter birth.

For some time now, the aetiology of Neural Tube Defects has cited diet and environmental factors. Clinical studies have confirmed that taking a vitamin called Folic Acid reduces the risk of developing a Neural Tube Defect. If all women of child-bearing age took 0.4 mgs of Folic Acid every day before conception and at least until the end of the first term of pregnancy, 50 to 70% of potential cases of anencephaly and Spina Bifida could be prevented.

experienced specialist using a high-resolution ultrasound scan can detect an anencephaly as early as the 10th week. In less-than-ideal circumstances, however, an anencephaly cannot be picked up or ruled out by an ultrasound scan until the 16th week of the pregnancy. AFP levels can be measured via a maternal serum screening test (blood test). If levels are high, there is a risk that the child may be suffering from an NTD.

Almost all teenagers get acne at one time or another. You haven't done anything to cause your acne. It's not your fault if you have it. Pimples are caused when oil ducts in the skin get plugged up and then burst, causing redness and swelling. Although there are many myths about acne, the following are the three main factors that cause it. When you begin puberty, certain hormones, called androgens, increase in both males and females.

Several factors contribute to the development of acne. The primary problem is that the abnormal flaking of cells inside the hair follicle leads to the formation of a plug. The plug can enlarge and even rupture the hair follicle. A ruptured hair follicle spills its contents of oil and debris into the skin where it leads to swelling and causes redness (inflammation).
