Background: In Vietnam, surgery or aspiration is preferred to treat thyroid cysts however each of them still have limitations. Purposes of this study were to evaluate the efficacy and safety of ethanol ablation in treating thyroid cysts and determine factors that predict the outcome of treatment. Methods: This prospective study was approved by the Ethics Committee of the Institutional Review Board of Family hospital and written informed consent for procedures was obtained. From May 2018 to March 2019, 23 patients who underwent treatment for thyroid cysts by EA were enrolled in this study and were followed up for 1 month at Family hospital. The primary endpoint was efficient after one month as the volume reduction ratio was ≥ 50%. Secondary endpoints were improvements in symptoms, cosmetic scores, and safety. Multiple logistic regression analysis was used. Results: In the finding, from May 2018 to March 2019, only 17 patients who matched inclusion criteria were included in the analyst, including 7 purely thyroid cysts, and 10 predominantly cystic nodules. Mean volume decreased significantly from 5.21 ± 3.37 ml to 2.35 ± 2.52 ml in corresponding to 52.87% of volume reduction with p < 0.05. Ethanol ablation (EA) success rate was 52.90% after 1 month. Symptoms and cosmetic scores were improved significantly. The thyroid function was constant. No adverse events occurred. Purely thyroid cyst was a predictive factor contributing to the success of EA. Conclusion: EA seems likely to be a safe and an efficient therapy for patients who had purely or predominantly cystic thyroid nodules.

Efficient Elimination

In many animals, including us, the genetic sex is determined at fertilization by sex chromosomes. Seemingly, the sex determination (SD) in human and animals is determined by the amount of constitutive heterochromatin on Y chromosome via cell thermoregulation. It is assumed the medulla and cortex tissue cells in the undifferentiated embryonic gonads (UEG) differ in vulnerability to the increase of the intracellular temperature. If the amount of the Y chromosome constitutive heterochromatin is enough for efficient elimination of heat difference between the nucleus and cytoplasm in rapidly growing UEG cells the medulla tissue survives. Otherwise it doomed to degeneration and a cortex tissue will remain in the UEG. Regardless of whether our assumption is true or not, it remains an open question why on Y chromosome there is a large constitutive heterochromatin block? What is its biological meaning? Does it relate to sex determination, sex differentiation and development of secondary sexual characteristics? If so, what is its mechanism: chemical or physical? There is no scientifically sound answer to these questions.
