Hipotermia post febrila de 9 nopți consecutive la un copil de 2 ani și 8 luni - #20677

Dear Doctor, Could you please help us with a problem concerning my daughter? I would greatly appreciate a response from a physician. My daughter is 2 years and 8 months old. For approximately one year, I have noticed that after viral illnesses or episodes of fever, her body temperature drops at night during sleep. So far, this has occurred three times, and each episode lasted 2–3 nights before her temperature returned to normal. Currently, however, she has experienced 9 consecutive nights in which her temperature drops to around 35°C, and it would likely drop further if we did not place warm water bottles near her. During the day, she is well, her temperature is normal, she is active, plays, and eats. However, we are very concerned at night and fear letting her sleep alone. Routine lab tests have come back within normal limits, but we do not know the cause and are unsure what should be done to stabilize her temperature. We have consulted three pediatricians so far, but none could determine the cause. Initially, it was suggested that this could be a reaction to antipyretics, but it has now been 9 days, and the temperature has still not stabilized. We are from Câmpulung Argeș. We went to the hospital there when her temperature was 34.9°C, but they only performed routine tests and said they did not know what was happening. We visited another city, where we were told they had not encountered such cases before and recommended consulting an immunologist and a neurologist. In another place, we were advised to try endocrinology as well. At the endocrinology consultation, the doctor said she is developing normally and there does not appear to be any problem. However, for our peace of mind, we were asked to do cortisol, FT4, TSH, and ACTH tests. These tests can only be done on Monday, and we are worried that something might worsen before then. We were recommended to see Dr. Cochino, but we do not know how to reach him, as he is only at IOMC and we have been unable to schedule an appointment. Could you please advise us on where we should seek help, which specialists to consult, or what steps we should take to investigate this issue? Thank you very much for your time and guidance!
