What information should parents provide at the time of consultation for patients with dwarfism? What are the tests that need to be done? Parents of children with dwarfism should provide the following information when they visit the hospital: 1. the mother’s pregnancy status, and the baby’s condition at birth, whether the birth was difficult, asphyxia, and what type of delivery method was used, height and weight at birth, etc. 2. Annual height growth rate. 3. Parents’ height and youth development, and whether there is short stature in the family. 4.Intellectual development, the presence of chronic hepatitis, kidney disease, etc. The child needs routine blood and urine tests, liver and kidney function tests and thyroid hormone level tests when he arrives at the hospital, and karyotype analysis for girls. Next, x-rays of the left wrist and metacarpal fingers are needed to measure bone age and determine the child’s bone growth, the degree of epiphyseal closure and growth potential. If necessary, blood tests for growth hormone and insulin-like growth factor levels will be taken. In addition, if short stature is considered to be growth hormone deficiency, a growth hormone stimulation test is required for diagnosis. MRI of the skull is performed in all children with short stature to rule out the possibility of congenital developmental abnormalities or tumors.
