    IS THERE A RELATIONSHIP BETWEEN SERUM IGF-1 AND THYROID NODULE, THYROID OR OVARIAN VOLUME IN POLYCYSTIC OVARIAN SYNDROME?
    (Editura Acad Romane, 2021) Topaloglu, O.; Evren, B.; Uzun, M.; Yologlu, S.; Guldogan, E.; Sahin, I
    Context. Studies investigating the association between serum IGF-1, and thyroid nodule, ovarian or thyroid volume in polycystic ovarian syndrome (PCOS) are limited. Objective. We aimed to analyze the association between serum IGF-1 level, and ovarian or thyroid volume, or thyroid nodule in PCOS. Design. The study was performed between June 2017 and August 2019 as prospective design. Subjects and Methods. Adult females with new-onset PCOS were included. The patients having comorbid illness, or using medication were excluded. Basic tests, thyroid and ovarian sonography were performed. The patients were grouped according to thyroid nodule(absent/present) and ovarian volume (<10mL/>= 10mL). We planned to find a positive association between IGF-1, and thyroid nodule, thyroid or ovarian volume in PCOS. Results. Of total 118 patients, 11(9%) had thyroid nodule. The patients with thyroid nodule had a higher ovarian volume (p=0.006). No correlation was found between GH or IGF-1, and thyroid or ovarian volume. IGF-1 was not a predictor for thyroid nodule or higher ovarian volume. Thyroid nodule was a significant predictor for higher ovarian volume. Conclusion. Our study is the first to analyze the association between IGF-1 and thyroid nodule in PCOS. We found that thyroid nodule was associated with thyroid and ovarian volume, but IGF-1 was not associated with thyroid nodule, thyroid or ovarian volume.

    Is there association between QRS-T angle, and hormonal and sonographic features in polycystic ovarian syndrome?
    (Verduci Publisher, 2020) Topaloglu, O.; Cimci, M.; Yologlu, S.; Sahin, I
    OBJECTIVE: Polycystic ovary syndrome (PCOS) is a complex disorder comprising ovulatory dysfunction, hyperandrogenism, and polycystic ovaries (PCO). Several studies have used electrocardiography (ECG) to assess PCOS patients. We aimed to analyze the associations among QRS-T angle, hormonal parameters, and ovarian and thyroid sonography in PCOS. PATIENTS AND METHODS: Adult females with PCOS, but without comorbid illness, were included in our study. Demographic and clinical features (body mass index, Ferriman-Gallwey score, phenotype) were analyzed, as well as laboratory test results. Based on standard 12-lead ECGs, frontal plane QRS-T angles were calculated, defined as the angle between the mean QRS and the mean T vector, and verified with automatic instrument measurements. Values within the range -46 to + 59 degrees were classified as normal, and those out of this range as abnormal. Patients were divided into groups according to the presence of thyroid nodules, echogenicity (normal/decreased), and vascularity (normal/increased) based on thyroid sonography, and by mean ovarian volume (MOV = 10/< 10 mL) or apparent PCO based on ovarian sonography. RESULTS: The mean age of the 92 patients was 22.68 +/- 4.58 years; 11 patients (11.9%) had abnormal QRS-T angles. Demographic, clinical, electrocardiographic, and laboratory parameters were similar between the normal and abnormal QRS-T angle groups, with the exception of MOV, which was higher in the latter group (p=0.032). Among all clinical and laboratory parameters, only MOV was a strong predictor of abnormal QRS-T angle (p= 0.016). CONCLUSIONS: Our study is the first to analyze the association between the QRS-T angle and hormonal and sonographic features of patients with PCOS. A small percentage of patients had abnormal QRS-T angles, and a large MOV was a strong predictor of this abnormality.
