Introduction: The role of F-18 FDG PET/CT in follow-up of differentiated thyroid cancer (DTC) is well established. Molecular markers were shown to be related with malignancy risk of thyroid nodules and prognosis of DTC. The goal of this study was to assess the relation of molecular markers such as NIS, Galectin-3, PTEN, Ki-67, p53 with PET positivity and malignancy of thyroid.Methods/design: We evaluated patients who had 18-FDG uptake in thyroid gland at...

Introduction: Lymphocytic hypophysitis is an uncommon disease of the pituitary gland mimicking pituitary macroadenoma on magnetic resonance imaging (MRI).Case: A 37-year-old female admitted to our clinic with headache, amenorrhea, polyuria and history of pituitary microadenoma. On laboratory examinations, prolactin level was mildly elevated (42 ng/ml) and FSH–LH levels were normal (2.4–4.04 mIU/ml) despite the low estrogen level (<20 pg/ml)...

Background: The 4th edition of World Health Organization (WHO) classification of pituitary tumors recommended evaluation of tumor proliferation and invasion to identify aggressiveness. We aimed to assess the relationship between Ki-67, mitotic index, P53 expression, invasion and recurrence risk in pituitary adenomas.Methods: Among 601 patients who underwent TN/TS adenomectomy between 2001 and 2016, 101 patients (16.8%) who had tumors with Ki-67 index &#8...

Introduction: Subacute thyroiditis is an iflammatory disease of the thyroid gland characterized by pain, tenderness and swelling in the neck. Less frequently, it may present with painless or silent thyroiditis that occurs spontaneously or in the postpartum period. In a few studies in the literature, urinary iodine was reported to be high in patients with postpartum thyroiditis, but it was not evaluated in patients with subacute thyroiditis. We aimed to evaluate urinary iodine ...

Introduction: Pregnancy or lactation related osteoporosis (PLO) is very rare. It usually occurs in the third trimester or in the early post partum period and manifestations are severe back pain and loss of height due to vertebral fractures. Its etiology is not well understood. Classical treatment is cessation of lactation, calcium and Vit-D supplementation and biphosphanates in chosen cases. All osteoporosis drugs are approved mainly for post-menouposal osteoporosis a...

Plant growth factors are used commonly in agriculture. The effect of these factors on human health is unknown. Gibberellins are the most commonly used growth factors that have the structure of Diterpenoid acid. One of the gibberellins (GA3) induces tumor formation in mice but the mechanism of action is not known. We here examined changes in levels of GH and IGF-1 and examined whether there is a correlation between growth factors’ levels and weight changes.<p class="ab...

Backgorund: Adrenal incidentalomas (AI) are lesions discovered incidentally on imaging without clinical symptoms or examination findings. AI can produce hormones in 5-30% of cases. Autonomic cortisol secretion (ACS) is the most common of these. Although ACS is asymptomatic, it increases the risk of metabolic disorders.Methods: Patients aged ≥18 years with adrenal adenoma and upper abdominal MRI who presented and were examined in the endocrinology o...

Introduction: Parathyroid carcinoma (PC) is a rare endocrine malignancy which accounts for 0.005% of all cancers and less than 1% of primary hyperparathyroidism cases. This uncommon tumor usually occurs during the fifth decade of life, with equal frequency in both sexes, and has an indolent but progressive course. It’s frequently symptomatic and patients may have high values of serum calcium and parathyroid hormone (PTH) with a palpable cervical mass. PC generally occurs ...

Introduction: Thyroid carcinoma is common in young women. Radioactive iodine (RAI) therapy has been confirmed as a useful treatment in the management of differentiated thyroid carcinoma (DTC). For women with DTC, the effect of RAI therapy on gonadal and reproductive function is an important consideration. We aimed to evaluate effects of RAI therapy on ovarian function.Method: Women younger than 40 years old and diagnosed with thyroid cancer that required...

Due to inhibition affect on proliferation, motility, resistance to apoptosis and growth of metastasis, the epidermal growth factor receptor (EGFR) inhibitor erlotinib and vascular endothelial growth factor receptor (VEGF) and EGFR inhibitor vandetanib are viable treatment options for treatment of advanced non-small cell lung cancer and thyroid cancer respectively. Advanced non-small cell lung carcinomas (NSCLC) or medullary and differentiated thyroid carcinomas (MTC and DTC) m...
