VITAMINS AND THEIR SIGNIFICANCE



Vitamin is a term applied to a group of substances which exist in minute quantities in natural foods, and which are necessary to normal nutrition, especially in connection with growth and development. Vitamins are widely used for medical purposes; many of them are produced synthetically. Different kinds of vitamins are designated by letters of the Latin alphabet. There are several groups of vitamins. All of them are very necessary for the life of the organism.

Vitamin A is found in cod-liver oil, eggs, liver, milk, butter and most green vegetables. Deficiency of vitamin A is considered to be responsible for serious inflammation of the eyes, various skin eruption, defective development of the teeth.

Vitamin B is present in the seeds of grains. The best sources of this vitamin are believed to be flour, bacon, liver, eggs. Its deficiency may result in a form of neuritis with muscular weakness, heart failure, etc., which is known as beri-beri.

Vitamin C is available in fresh fruits, berries, green vegetables, milk, meat and other fresh foods. It is quickly destroyed by high temperature. The deficiency of vitamin C leads to scurvy.

Vitamin D is of special importance for the growth of children. Only a few foods contain vitamin D naturally, viz. cod-liver oil, caviar, egg yolk, fresh vegetables and milk to a greater or lesser degree.

Cod-liver oil is a product with a high vitamin D content. Vitamin D is manufactured in very large amounts at the plants. The deficiency of this vitamin in children may cause rickets. Since vitamin D is known to be preventive as well as curative for rickets the doctors often prescribe the course of vitamin D treatment.

A lack of vitamins in food or an insufficient amount of them results in a serious breakdown in the organism. Prolonged deficiency of any vitamin is sure to result in a disease known as avitaminosis, e.g. scurvy, beri-beri, rickets. Most avitaminoses are accompanied by reduced working capacity, rapid fatigue, a sharp decrease in the resistance of the organism to infection, incorrect development and retarded growth (in children), etc. To prevent avitaminoses infants should be daily given cod-liver oil and fresh fruit and vegetable juices.

Any person using a diet containing such foods as milk, eggs, butter, cheese, fat, fish,

bread, fresh vegetables and fruit obtains a sufficient amount of vitamins to be protected from avitaminoses.

OBESITY

 

 

Obesity in children is actually more frequent than the number of overweight children who came for treatment. Parents are inclined to overlook obesity in a young child and to resent having attention to it.

Pathogenesis. Children grow fat when they persistently eat more than they need. At the same time there is usually marked physical inactivity. Obesity is only the symptomatic expression of some underlying disturbance in the weight-regulatory mechanism. In most children the reflex tends to persist into adult life.

Symptoms. Physical complaints due directly to the burden of weight are relatively rare in otherwise normal obese children. However, we know obesity to be a troublesome complication in children with cardiac conditions, diabetes and orthopedic disorders. Increase in blood pressure is frequently associated with severe degrees of obesity. Fatigue, perspiration, poor coordination and shortness of breath may be due to overweight, but these symptoms may also be related to emotional factors. The real suffering is experienced in the field of social relations. They often become objects of ridicule and are excluded from the activities of their age group. The social and psychological problems which obesity creates for a child become more serious with increasing age. Obesity in an adolescent may lead to complete withdrawal.

Treatment. As a physiological problem the treatment of the obese child is simple. Doctors suppose restriction alone or combined with increased physical activity to invariably result in a predictable loss of weight. In a rapidly growing child who is only moderately overweight, it may not be necessary or desirable to plan for weight reduction. It may be preferable merely to retard or arrest the rate of gain until the child grows up to his weight. Caution should be exercised in employing complete starvation, a procedure that has been recently recommended.

 

Active words to remember:

 

Obesity, to be inclined, avoidance, to persist, to respond, to achieve, to justify, to predispose, perspiration, to experience, adjustment, restriction, to retard, to arrest, caution, starvation, withdrawal.

CRACK COMES TO NURSERY

 

More and more cocaine using mothers are bearing afflicted infants. Numerous reports that appeared in 1980s showed that cocaine use by pregnant women could cause serious physical and mental impairment to their newborns. It was another warning that the snowy white drug was not as harmless as some believed. Since then the situation has only changed for the worse. Despite wide-spread publicity many pregnant women underestimate the extent of the problem. There are women who would not smoke and would not drink but they can’t stay away from cocaine.

Cocaine is a powerful stimulant drug that has become increasingly popular and available in the United States. Smoking cocaine results in short periods of intense euphoric feelings, during which energy and self-esteem are enhanced and anxiety is decreased. However, within hours of use cocaine rebound effects result in anxiety, exhaustion and depressive feelings. The dependent person has to take cocaine repeatedly to avoid these “crash” rebound effects. Because of cocaine’s low molecular weight and its water and lipid solubility it readily crosses the placenta and the fetal blood brain barrier.

The growing number of women are using crack, the cheap purified form of cocaine that plagues American’s inner cities and has spread into middle class suburbs. More than 100.000 babies born in the US annually are believed to have been exposed to cocaine or other drugs during the critical period of fetal development. Doctors found that cocaine like heroin and alcohol could be passed from the user-mother to the fetus with disastrous results.

As doctors see more and more crack-damaged infants – many of them premature – a clear picture of the effects of the drug is emerging. It is not a pretty one. Because a mother’s crack binge triggers spasms in the baby’s blood vessels the vital flow of oxygen and nutrients can be severely restricted for long periods. Fetal growth including head and brain size may be impaired, strokes and seizures may occur and malformations of the kidneys, genitals, intestines and spinal cord may develop. If cocaine dose is large enough, the blood supply can be cut so sharply that the placenta may tear loose from uterus, putting mother in danger and killing the fetus. In this way even one “fit” of crack can irreparably damage the fetus. At birth the babies display obvious signs of crack exposure – tremors, irritability and lethargy that may belie the seriousness of the harm done. These symptoms may disappear in a week or more but the underlying damage remains.

Cocaine-exposed neonates have been found to have lower birth weight, smaller head circumference, inferior visual and auditory orienting skills, poorer motor abilities, decreased consolability and more abnormal reflexes.

Because there is no specific treatment for cocaine babies doctors must work with mothers. Parenting programs are teaching women how to handle the baby’s long bouts of inconsolable crying and unresponsiveness. But such programs are usually designed for motivated women with some financial resources.
