Background: Reproductive health is an integral part of a women’s general health and is influenced by various endogenous and exogenous factors.Objectives: The aim was to detect the possible effects of COVID-19 on women’s reproductive health.Methods: We created an anonymous survey about reproductive health and shared it with women of reproductive age. Regarding menstrual cycle characteristics all women used the smartphone a...

Aim: Metabolic syndrome rates have been studied especially in adrenal gland secreting cortisol and studies on nonfunctional adenomas are limited. In this study, we investigated metabolic parameters and metabolic syndrome frequency in non-functional adrenal adenomas (NFA).Materials and methods: In our study, 55 patients (15 men (27.3%), 40 women (72.7%) who were diagnosed incidentally, unilateral or bilateral localized, hormone-inactive, and with adenoma-...

Background: İt is known that there is a relationship between some diseases and blood groups.Objective: The objective of our study is to investigate how often ABO and Rh blood groups are seen in benign thyroid diseases, especially in autoimmune-mediated thyroid diseases, and hence whether there is an association between blood groups and thyroid diseases.Method: A total of 958 patients who were followed due to any benign thyroi...

We would like to present a case of primary hyperparathyroidism presumably present with clinically large cystic parathyroid adenoma with multiple destructive skeletal lesions, which is of course referred to bone metastases.Case: A 58-year-old male patient was admitted to the orthopedy polyclinic with left leg pain and on the MR imaging performed here, multiple lytic lesions compatible with metastasis to the tibia and fibula were detected. He was directed ...

Physiological circulating concentrations of estrogens are very low in men and postmenopausal women (<50 pg/ml), which presenting analytical challenges. Immunoassays can detect as low as 30 pg/ml, but cross-reactivity is a concern. Liquid chromatography–tandem mass spectrometry (LC–MS/MS) offers greater specificity than immunoassays, but ionisation of estrogens is inefficient. Derivatisation, which introduces charged moieties, may enhance ionisation. Dansylated de...

Introduction: In pregnancy, the incidence of Primary Hyperparathyroidism is 1%; and there are 80% adenoma, 15% parathyroid hyperplasia, 3% multiple adenoma, and 1% parathyroid carcinoma in its etiology. In pregnancy, serum calcium (Ca) levels may not rise as much as expected. This is associated with hypoalbuminemia, GFR increase, placental Ca transfer, and inhibition of PTH–related bone resorption by estrogen. In pregnancy, hyperparathyroidism is asymptomatic at a rate o...

While pituitary adenomas (PA) usually occur as a sporadic disease, an increasing number of patients are recognised with a family member also suffering from a PA. If no other syndromic features are present, these families are categorised as FIPA. In published studies, 20% of the FIPA families, 20% of sporadic childhood and 13% of sporadic young-onset (≤30 years) acromegaly patients carry a germline AIP mutation. As familial disease is more aggressive, family scre...

Familial isolated pituitary adenoma (FIPA) occurs if two or more members of a family develop pituitary adenoma with no features of multiple endocrine neoplasia type 1 or Carney complex. FIPA is an autosomal dominant disease with incomplete penetrance. FIPA families can be divided into two distinct groups based on genetic and phenotypic features. In 20% of FIPA families mutations have been identified in the aryl hydrocarbon receptor interacting protein (AIP) gene. The AIP-posit...

Background: It is well established that 1,25-dihydroxyvitamin D3 (1,25-D3) inhibits cell growth and induces apoptosis in numerous tumors. Increased expression of 1,25-D3 inactivating enzyme, (24-hydroxylase - CYP24A1), has been observed in numerous thyroid cancer cell lines after calcitriol treatment in vitro. We examined the expression of CYP24A1 as well as the activating 1-α-hydroxylase (CYP27B1) gene in human thyroid cancer tissue.Methods:...

It is established that somatic oncogene mutation (BRAF, NRAS, HRAS, KRAS) and gene translocations (RET/PTC, PAX8/PPAR-gamma) are associated with the development of thyroid cancer. Somatic single nucleotide polymorphisms were analyzed by LigthCycler melting method, while translocations were identified by real-time polymerase chain reaction technique. In 22 intraoperative thyroid tissue samples (11 pathologic and 11 normal). In tumorous sample 3 BRAF, 2 NRAS and one HRAS mutatio...
