Signs of pregnancy

Stay healthy when pregnant:

Every pregnant woman's life is a special time. This is a period of a woman to pay the most attention a healthy lifestyle, reasonable, balanced diet, harmful factors that may damage the embryo or fetus's health tax.
Alcohol is considered the most safe during pregnancy alcohol consumption is not, because the minimum amount of alcohol and alcohol can affect fetal development, resulting in the so-called. Fetal alcohol syndrome (FAS in the United States was diagnosed in 1750 newborns per year). FAS includes mental retardation, fetal growth retardation, including weight, height and head of the children, craniofacial, cardiac abnormalities, behavioral disorders perimeter. FAS is preventable, but you can not heal when damaged, but drinking during pregnancy. They are particularly dangerous spirit, but should avoid wine and beer, because the minimum drinking (1 drink per day) can cause fetal developmental defects, especially in the organs begin to form during pregnancy. Mild to moderate consumption of these beverages may lead to premature delivery.
Smoking, drugs and a very long time to have a clear recommended drugs: no smoking, no consumption of drugs. Obviously related to smoking, such as low birth weight, prematurity, low gestational age, sudden infant death syndrome and poor pregnancy outcome 1 age, birth stillbirth. The good news is that a significant number of pregnant women (40%) spontaneously stopped smoking during pregnancy, but 2 / 3 of these women do not abstain from smoking within the year of birth. Medication during pregnancy should not arbitrarily, but only in the doctor's recommendations, there is a drug consumption indicators, and categories, which for the safety of the fetus. Particularly sensitive period, the first three months, fetal organ development. In the systemic circulation, not only solved the rectal suppositories oral medication (oral), but also transdermally (through the skin) and, therefore, caution is necessary, mandatory, on the preparatory work of the doctor. Avoid the use of pesticides, herbicides and pesticides.

Coffee For most pregnant women, drinking two cups of coffee per day (containing approximately 150 milligrams of caffeine) is not dangerous, but we must avoid a lot of caffeine, 4 cups of coffee a day, or higher than the amount of over 500 mg of caffeine more pregnant. Caffeine (which includes chocolate, some soft drinks) 15 minutes after drinking coffee affect the central nervous system. Slight increase in blood pressure, heart rate and stimulate the body to reduce the amount of fluid in the urine, but the good hydration is the basis for a healthy pregnancy. Some studies suggest that more than 600 mg / day of caffeine can cause low birth weight.
Nutrition listeriosis caused by Listeria monocytogenes bacteria, and toxic and cause mild to severe gastrointestinal illness with nausea, vomiting and diarrhea is characterized. In severe cases of poisoning can cause abortion, that abortion, neonatal meningitis or sepsis. To prevent this situation from food-borne diseases, it is best to wash hands frequently when preparing food, keep food warm, fresh eyes, thoroughly wash fruits and vegetables.

Skin cancer

In some cases skin cancer appears in area skin who is often in sun light or UV radtiation. Malignant skin cancer coming in backs of a man and legs of women.
Another risk for genetic, tendency cancer skin usually coming on person who have light skin, green or blue eyes, red or blue hair and to much type of radiation.


Melanoma is skin disease in wich cell cancer appears in cells who gives colors to skin.  Melamoma is usually comming in adults , but sometimes it can be found in the child and adolescent. Skin protect body of heat, light, infection and injury. Consistis of two main layer, Melanocytes are in epidermis and they contain melanin that gives skin color.
Melanoma  is hard severe form of cancer  than the more common forms of skin cancer, which begins in the basal plate or epidermal cells. Melanoma can spread rapidly to other parts the body through the lympatic system of by blood. Lymph nodes small lesion in the form of beans that are fonud in all parts of the body, they produce and store cells that serve to fight infection.

Down syndrome

Aproximately one of 650 newborn children is born with Down syndrome,with cromosomic disorder which is happening with one chromosome more. That disorder is not allowing mental and fisical growth of a child. Down syndrome is possible everywhere in all races regardless to economic situation or way of living. Better study of Down syndrome is helping us to help ill people and give them chance for easier life.

Why is Down syndrome happening?
Human body is made of large number of cells. Every cell has a core where are located hereditary materials also called genes. Genes create group of genes and they are complexed in spiral which we call chromosomes. Every healthy person has 46 chromosomes or 23 pairs. Down syndrome is caused by parents gametes,when they give to embryo one chrosome more than usual. That is syndrome nobody can predict. Down syndrome is also called trisomy 21 because there are three copies of 21st chrosome. Despite years of studying,scientists still doesnt know why is that one chromosome happening. It is only known that women from 35 and older have bigger possibility to born child with Down syndrome.
It is known over 50 characteristics of syndrome. In dyagnosis mother can see right after birth,that baby is having specific look. Then doctor is taking some medical searches of blood which is called karyotype. Karyotype is showing number of chromosomes and their size and look. Here are some specific characteristics of ill children:
Muscular hipotony, reduction of tension of muscle
     Wide neck. The child may have a short, wide neck with excess skin and fatty tissue
     Inclined position of eye opening (the person's facial features mongol race, of which he was         commonly called "mongolodysm")
     A round face straight profile
     Abnormal form of ears
     Quick hands on the palm of a specific transverse furrow
     Small mouth and nose with a disproportionately large tongue
     Short and broad hands and feet, often there is a gap between the big toe and the adjacent finger
     Short rib cage of an unusual shape
     small head

Breast cancer

British scientist from Oxford University published that genes have limited meaning in growth of breast cancer,and they are independent of individual way of living. This facts include weight,nutrition,consumation of alcohol and breast feeding and it is science proved that theese facts have greater impact on cancer than genes. Researches after collected results from 18 000 women conclude that healthy living has great importance regardless genetic predispositions to develop breast cancer. Breast cancer is the most common form of cancer in hi-developed countries and takes half million lifes by vear. It is estimated that so far 18 identificated often genetic variants is releated 8 percent of cases of this disease. Taking results from one study 40 percent  of breast cancer is possible to stop by keeping healthy living,keeping healthy weight,stop consumation alcohol,fitness and breast feeding.
