Can children use orthokeratology?

summary

Thyroid radionuclide examination is generally used for thyroid nodules more than one centimeter, accompanied by low thyroid stimulating hormone levels. In radionuclide imaging, "hot nodule" is almost benign nodule, "warm nodule" is mostly benign tumor, less cancer, a single "cold nodule", fuzzy edge is more likely to be malignant. Can children use orthokeratology? Next, I'd like to share my views with you.

Can children use orthokeratology?

Abnormal results: in patients with hyperthyroidism, thyroid blood flow increased significantly due to hyperthyroidism. Therefore, when hyperthyroidism patients were injected with imaging agent for 8-10 seconds, thyroid was developed, and its radioactivity was higher than that of carotid artery, and thyroid imaging was rapid and clear. The rapid growth of thyroid malignant tumor increases the local blood flow of the nodule. The patients with "hot nodule" in static imaging are mostly toxic thyroid adenoma, while the patients with "cold nodule" in static imaging are more likely to have malignant tumor.

The early clinical manifestation of thyroid cancer is not obvious. Patients or family members and doctors occasionally find a hard and uneven mass in the neck thyroid, most of which have no self-conscious symptoms. The mass in the neck is often an asymmetric hard mass. The mass of thyroid nodules can gradually increase, move up and down with swallowing, and can be fixed by invading the trachea. The mass is easy to produce compression symptoms earlier, such as hoarseness, When the jugular vein is compressed, signs such as venous distention and facial edema on the affected side may appear, which is one of the characteristics of thyroid cancer, such as lung metastasis and bone metastasis, and even pathological fracture. In the case of cervical cancer, thyroid should be carefully examined, and hypothyroidism is more common in the late stage.

In addition to functional autonomous thyroid tumor, most benign thyroid tumors are solitary thyroid nodules, and a few are multiple nodules. Most of them are single, round or oval, with smooth surface, clear boundary, solid texture, no adhesion with surrounding tissues, no tenderness, and can move up and down with swallowing. The tumor is usually several centimetres in diameter, and rarely seen in large cases. Giant tumor can produce the phenomenon of compression of adjacent organs, but does not invade these organs, such as compression of the trachea, causing organ displacement.

matters needing attention

Unsuitable population: pregnant more than 12 weeks, lactation. Note before examination: the preparation of patients before scanning is the same as 131I uptake function test. Because the dose of radionuclide used in thyroid scanning is greater than that of 131I uptake function test, the scanning should be carried out after all tests. If the scanning has been done, the 131I uptake function test should be carried out 2-3 months after the scanning. Inspection requirements: actively cooperate with the doctor's requirements.
