Patient: Hello, my little girl, born in September 2001, found her breasts protruding last summer, pubic hair is still visible, and she is growing fast. My daughter, born in September 2001, found her breasts protruding last summer (she didn’t pay much attention to it before), her pubic hair was faintly visible, and she was growing fast. On October 25, she went to the local children’s hospital to see her growth and development. ultrasound showed that her uterus and ovaries were larger than her age, her thyroid gland was enlarged, and her breasts were developing. x-ray (bone age) showed early fusion, blood test showed high estradiol (33) and serum lactogen (22.17), and on November 19, she was contacted for an MRI. The doctor said to take the medicine first, and gave 2 months of the big Yin pill, said to eat after to review, a bottle of cap every day in two times to eat, a bottle to eat 5 days. The child began to eat on November 21, probably because the amount is small, a week to finish a bottle, see the breast or no change, after strictly in accordance with medical advice to take medicine, January 9, 2010 to finish the medicine, the breast than the previous smaller and softer, but did not go down, height 139 cm. Hello, what are the treatment options? I also want to know if I have to take the injection, there is a saying, the actual height of the bone age height, you do not have to take the injection, mainly because the late addition of growth hormone afraid to affect the child, her psychological impact, and whether you can see the bone age film to determine the actual bone age of the child. A: The child’s height is not very high in the same age children, mainly depends on the bone age, bone age more than a year, height minus 5 centimeters, so the bone age is the key, but should also ask the doctor to look before making treatment plans. Patient: Thank you very much for your timely reply. At that time, the doctor said that the bone age should be 10 years old, and they said that the detailed assessment of bone age is a lie. Is it necessary to do the stimulation test to determine whether it is true precocious puberty, and if it is true precocious puberty, is injection the only treatment method? A: Only injection is the only effective treatment for true precocious puberty. Although doctors have different perceptions, bone age is still an effective indicator for diagnosing precocious puberty and can determine the actual developmental age of the child.
