Vitamin D is an essential steroid involved in bone metabolism, cell growth, differentiation, and regulation of the minerals in the body. The main sources of this vital vitamin are adequate diet and photosynthesis in the skin. The aim of this study was to investigate the efficiency of vitamin D synthesis in 48 premenopausal women (14-44 years) in relation to(More)
Langerhans cell histiocytosis (LCH) is a rare disease in which the most common endocrine manifestation is diabetes insipidus (DI). Data on anterior pituitary function in patients with LCH are limited. Thus, the present study investigated anterior pituitary function in LCH patients with DI via the evaluation of clinical and radiological findings at disease(More)
The aim of the study was to assess the effect of dopamine agonist (DA) withdrawal, the current recurrence rate of hyperprolactinemia, and possible factors that predict recurrence in patients with prolactinoma. We evaluated DA withdrawal in 67 patients with prolactinoma (50 female/17 male) who received DA treatment for at least 2 years and showed(More)
Hypopituitarism in adult life is commonly acquired and the main causes are known as pituitary tumors and/or their treatments. Since there are new insights into the etiology of hypopituitarism and presence of differences in various populations, more studies regarding causes of hypopituitarism are needed to be done in different ethnic groups with sufficient(More)
Pheochromocytoma usually presents with typical signs and symptoms, such as headache, sweating, and palpitations due to excessive catecholamine release. Few publications have reported that these tumors are capable of secreting a variety of bioactive neuropeptides and hormones other than catecholamines, resulting in unusual clinical manifestations.(More)
INTRODUCTION Cytokines play a crucial role in the pathogenesis of autoimmune thyroid disease, and recent studies have demonstrated an association between cytokine gene polymorphisms and Graves' Disease (GD) in different ethnic groups. The aim of the present study was to investigate the relationship of interleukin-6 (IL-6), IL-10, tumor necrosis factor-alpha(More)
Insulin-secreting pancreatic tumors and insulin-like growth hormone-secreting non-islet cell tumors can cause hypoglycemia. However, insulin-releasing paraganglioma or pheochromocytoma has almost never been reported. A 67-year-old female patient was admitted to our hospital because of headache, palpitation, perspiration, faintness, frequent sense of hunger(More)
BACKGROUND Clodronic acid, a first-generation bisphosphonate, has been successfully used in the treatment of high bone turnover states, Paget's disease and osteolytic bone metastases. However, controversies remain over its optimal dosage and method of administration in the treatment of postmenopausal osteoporosis. In this study we aimed to evaluate the(More)
OBJECTIVE In many pituitary tumor, immunohistochemical studies have been shown to be correlated with different aspects of tumor behavior.There is no study up to date in which markers of Ki-67, p53, VEGF were evaluated concomitantly in GH-secreting adenomas.This study aims to determine which marker has a major role in tumor behavior and whether these markers(More)
One form of prolactin (PRL) is macroprolactin with high molecular mass. Many macroprolactinemic patients have no pituitary adenomas and no clinical symptoms of hyperprolactinemia, it is controversial whether macroprolactinemia is a benign condition that does not need further investigation and treatment. In this study, we aimed to compare macroprolactinemic(More)
