* Hypoparathyroidism is the most common complication after a total thyroidectomy surgery. It becomes permanent after 6 months. * Untreated permanent hypoparathyroidism is a source of numerous complications in general and therefore requires lifelong replacement therapy resulting in a significant deterioration in quality of life. * The intraoperative use of indocyanine green (ICG) angiography has recently been described as a reliable means of detecting parathyroidism and predicting the risk of postoperative hypoparathyroidism. * This use could prove to be a way to preserve parathyroid in vivo and thus reduce post-operative hypoparathyroidism rates.
NCT07173621
The purpose of this study is to understand how placing Amnioeffect on patients having transcutaneous thyroid or parathyroid surgery affects surgery scar appearance, pain, and the ability to swallow and compare it to patients who do not have anything placed during surgery. The Food and Drug Administration regulates the use of Amnioeffect for homologous use. Both Amnioeffect application and no Amnioeffect application are considered standard of care; however, for the purpose of this study, the use of Amnioeffect during surgery will be considered the intervention, and no Amnioeffect application will be the standard of care.
NCT05022667
This study will see if the use of near infrared autofluorescence (NIRAF) detection with a 'Parathyroid Eye (PTeye)' for identifying parathyroid glands (PGs) during total thyroidectomy (TTx) is better than surgeon's detection alone. It compares risk, benefits and outcomes in TTx patients where NIRAF detection with PTeye for parathyroid identification is either used or not used.

NCT06738888
The investigators have previously proposed a prediction model for difficult transoral and submental thyroidectomy through a retrospective study. In order to better promote transoral and submental endoscopic approach for thyroid surgery and to set up an appropriate training course, the investigators aim to renovate and validate the prediction model through a prospective study.
NCT05294393
In the domain of endocrine gland surgery, thyroidectomy is the most common procedure. Patients report moderate to severe discomfort postoperatively, which is induced by a variety of mechanisms, the most common of which are cervical incision and surgical maneuvers. The other two causes are endotracheal intubation and neck overextension. Incisional pain, odynophagia, dysphagia, neck and shoulder pain have all been reported as sources of discomfort.However, it seems that this discomfort has a time limit, with a considerable decrease in pain scores that will last 24 to 36 hours. Pain is felt more profoundly within the first few hours after surgery, peaking at 6 hours, with patients requesting further analgesic medication. Surgical wound infiltration can inhibit this procedure by preventing the alginate signal from reaching the incision site's receptors. According to the multimodal analgesia trends, magnesium sulfate can be added to the ropivacaine solution. Magnesium acts as an NMDA (N-methyl-D-aspartate) receptor antagonist, inhibiting cerebral sensitization to peripheral pain stimuli while reducing pre-existing hyperalgesia. It becomes evident that this combination could contribute to attain the maximum analgesic efficacy. So, if any superiority of ropivacaine plus magnesium sulphate over ropivacaine could be demonstrated this would be very helpful in providing sufficient analgesic effects with a low incidence of adverse effects, while enhancing the option of one day surgery.
NCT05412680
Prospective study carried out with ICESP (instituto do Câncer do Estado de São Paulo) patients with thyroid disease with surgical indication
NCT06394466
The assessment of ovarian reserve is well established based on the dosage of anti-Mullerian hormone (AMH). The clinical applicability of detecting thyroid autoantibodies levels has been discussed as a potential marker of low-grade inflammation. There are no studies about the detection of these autoantibodies in infertile women. Our objective is to evaluate the association between ovarian reserve and thyroid function and its autoimmunity in infertile women seeking for assisted reproductive treatment (ART).Evaluation ot thyroid function in the first trimester in also be evaluated in women submitted to ART.

Since 2017, a revolution began in the departments of nuclear medicine, with the routine use of gamma-cameras with semiconductor. These gamma-cameras (which obtained the CE-marking in 2016), offer a technological breakthrough by providing an additional information. They allow "to quantify" for the 1st time in clinical routine conditions, the quantity of radioactivity, by means of a "SUVspect", in a volume of interest, while respecting the recommendations of best practice of the learned societies of French nuclear medicine (SFMN), European (EANM) and American (SNM), without injection of tracer nor acquisition or additional irradiation. The SUVspect is therefore an indicator of the quantity of tracer in a given volume of acquisition. Until now, the interpretation criteria of scintigraphies are based on the homogeneity of distribution of a tracer in the explored organ (for single organs such as the heart or the thyroid, for example) or in the asymmetry of distribution of the tracer (for the double organs, such as the kidney or the joints). This new gamma-camera allows to study the distribution of the radio-tracers in "list" mode, allowing to retrospectively reconstruct the images in various ways (for example, by modifying the size of the matrix of acquisition, the energy windows, the time of acquisition). Therefore, we can simulate and propose modifications in current procedures. Every patient referred to our department of nuclear medicine to undergo a scintigraphy with a tracer of nuclear medicine (with a marketing authorization) can, while benefiting from an examination by this gamma-camera, to be the object of this study, and to profit from this additional information. So, without changing the diagnosis or the usual care, we wish to take advantage of this additional information to improve the criteria of interpretation of our examinations. This possibility being new, there is no available bibliography (our department is the 5th department of nuclear medicine in Europe to equip itself with this large field-of-view gamma-camera CZT, the DNM 670, made by General Electric), while 2961 articles speak about the SUVmax (in PET) in Pubmed.

NCT04745793
Iatrogenic injuries to the parathyroid glands during thyroid surgery or to the recurrent laryngeal nerve (RLN) do still occur, requiring often specialized management. Recently, it has been demonstrated that the parathyroid gland shows a significant autofluorescence. Using a commercially available Near-InfraRed (NIR) camera (Fluobeam®, Fluoptics©, France), the parathyroid glands can be clearly visualized by contrast-free fluorescence imaging. However it lacks real-time quantification of the fluorescence intensity. The hyperspectral imaging (HSI), which is a technology that combines a spectrometer to a camera system, examines the optical properties of a large area in a wavelength range from NIR to visual light (VIS). It provides spatial information real time, in a contact-free, non-ionizing manner. The HSI technology would add the spatial information, thus enormously enhancing the intraoperative performance. The aim of the proposed study is to identify the spectral features of the important neck target structures, in particular the parathyroid glands, using an appropriate deep learning algorithm, to perform an automated parathyroid recognition. Additionally, this study proposes to compare the detection rate of the hyperspectral based parathyroid recognition with the already existing NIR autofluorescence based recognition.
NCT06036576
The goal of this clinical trial is to investigate the influence of thyroxine supplementation on pregnancy outcomes in women with varying levels of Thyroid-Stimulating Hormone (TSH), who have experienced recurrent pregnancy loss in the first trimester. The main questions it aims to answer are: * Does thyroxine treatment improve pregnancy outcomes in women with TSH levels between 2.5 mU/L and 4 mU/L? * Is the effect of thyroxine treatment different in women with TSH levels higher than 4 mU/L? Participants will be grouped based on their TSH levels, into two groups - those with TSH levels between 2.5 mU/L and 4 mU/L, and those with TSH levels higher than 4 mU/L. They will then be given thyroxine treatment. Researchers will compare these two groups to see if the pregnancy outcomes differ based on the different TSH levels and thyroxine treatment.

the study aimed at evaluating efficacy of auto-transplantation of thyroid tissue after total thyroidectomy in benign thyroid disorders to keep the patient euthyroid with no need for life long hormone replacement therapy.
NCT01848171
Hypothyroidism is a common clinical entity which is often complicated by dyslipidemia. It is also reported increased risk for incidence of atherosclerosis and resulting coronary heart disease(CHD), heart failure(HF) and cardiovascular(CV) death. The effect of L-thyroxine replacement treatment on serum lipid and atherosclerosis is controversial in hypothyroid patients, especially in those with mild or moderate subclinical hypothyroidism. The present study was designed to investigate whether L-thyroxine replacement was effective in improving serum lipid profiles and retarding atherosclerosis progress. Studies have shown that hypothyroidism increased the risk of COVID-19 composite poor outcomes. This study also aimed to investigate whether L-thyroxine replacement therapy was effective in reducing the incidence and mortality of COVID-19, and in improving the severity of COVID-19 and COVID-19 related complications.
NCT05688007
This observational study aims to test the level of parathyroid hormone in pregnant women. The main question it aims to answer is: n Pregnant women, are the levels of serum PTH, calcium, magnesium, phosphorus \& albumin similar in both preterm and term births?
NCT05446012
Fallopian tubes participate in the incorporation of gametes and embryos into the endometrial cavity. It also provides an optimal environment for flattening and early embryonic development. Tubal pathologies can cause both primary and secondary infertility. This condition has been associated with overt and subclinical hypothyroidism. However, the effects of hypothyroidism on tubal activity are not fully known. Although a few animal experiment studies on this subject have been published, there is no study on this subject in the literature. Demonstrating that epithelial and smooth muscle cells of rat fallopian tubes express thyroid receptors in animal experiments showed that fallopian tubes are targets for thyroid hormones. Again, in an animal experiment study, it was revealed that thyroid hormones have an important control on glycogen and lipid storage, lipid signaling and lymphocyte infiltration, which have an important role in maintaining the microenvironment in the rat fallopian tubes. This microenvironment is necessary for fertilization, sperm capacitation and gamete development. In another animal experimental study, it was thought that changes in the size of the epithelium of the fallopian tubes and cell metabolism in hypothyroid rabbits may affect oviductal activity and reproductive functions. An ectopic pregnancy is defined as a pregnancy implanted outside of the uterus. Ectopic pregnancy \>98% implants in the fallopian tube. The etiology of ectopic pregnancy is unclear, but tubal implantation is probably due to impaired embryo-tubal transport. This is due to changes in the tubal environment. Based on this information, we aim to determine the possible relationship between hypothyroidism and ectopic pregnancy in humans in our study.
NCT05510609
The purpose of this clinical trial is to investigate the accuracy of applying three-dimensional ultrasound on thyroid gland patients when determining a gland volume. The method will be compared to conventional b-mode ultrasound where three axis measurements (length, width, and depth) are evaluated in the ellipsoid model. The three dimensional (3D) method is utilizing optical tracking connected to the ultrasound image to form cross-sectional imaging. Patients enrolled in the study are set for complete thyroidectomies enabling a true volume of the gland by water displacement after excision. The aim is to find if this 3D method is more accurate in volume estimation than the ellipsoid model.
NCT04167423
Natural thyroid function changes during pregnancy. In up to tens of percent of pregnant women, these changes can lead to pathological fluctuations in hormone and antibody production. Although the effects on pregnancy and child development are well described, none has determined their influence on mother's emotional well-being and the quality of life. At present, universal thyroid screening in pregnancy in the Czech Republic is not covered by health insurance. The aim of the project is to change this situation by providing quality of life estimate for the cost-effectiveness model. This is a project of three specialized institutions aimed at mapping various aspects of the quality of life of pregnant women and describing the impact of thyroid disease on their lives. The project is a parallel study to a larger project Early screening for thyreopathy in pregnancy (CZ.03.2.63/0.0/0.0/15\_039/0009643) supported by the European Fund Operational Programme Employment through the National screening centre. The data will be collected through online questionnaire from women enrolled in the Early screening for thyreopathy in pregnancy (CZ.03.2.63/0.0/0.0/15\_039/0009643) who were screened for TSH, TPOAb and FT4.
