प्रश्न
A child suffering from Thalassemia is born to a normal couple. But the mother is being blamed by the family for delivering a sick baby.
(a) What is Thalassemia?
(b) How would you counsel the family not to blame the mother for delivering a child suffering from this disease? Explain.
(c) List the values your counselling can propagate in the families.
उत्तर
(a) Thalassemia is a group of autosomal recessive blood disorders characterized by severe anemia as a result of production of faulty haemoglobin chains. Mutations in the genes coding for the alpha, beta or delta chains constituting haemoglobin lead to the synthesis of improperly folded haemoglobin that is incapable of transporting oxygen efficiently.
(b) Thalassemia is an autosomal recessive disease, which means the mutation is carried on one of the autosomes, so the carrier can be any one of the two parents. It has an equal probability of coming from the mother or the father, so to just blame the mother for the child's abnormality is unjustified.
(c) The values counseling can propagate in the families are:
i. Give a healthy diet plan to the child
ii. Accepting their child with all his/her positives and negatives
iii. Neither of the parents is responsible for giving birth to a sick baby.
iv. The defect is caused by a random change in the genes of the child.
v. Encouraging the child to follow his/her treatment regularly and lead a happy and normal life.
vi. Support the child emotionally by talking about fear, anxiety, and depression or stress the child feels.
