Background: The polycystic ovary syndrome (PCOS) is often seen in reproductive age women. Although the ratio of insulin resistance is not knowm definitely in PCOS patients it is thought to be between 50 to 65%. Several studies have shown that low serum 25-Hydroxy Vitamin D (25(OH) D) levels are associated with high body mass index (BMI), insulin resistance, and waist/hip circumference, but it has not yet been clearly determined. In this study, we aimed to determine the correla...

Primary Hyperparathyroidism is a common endocrine disorder characterized with high parathyroid hormone (PTH) and calcium (Ca) levels. Although most of the patients are asymptomatic, some patients may be presented with renal, gastrointestinal, musculoskeletal, neurologic or cardiovascular signs associated with hypercalcemia or elevated parathyroid hormone related findings such as bone disease, nephrolithiasis, hypophosphatemia increased production of calcitriol, hypomagnesemia,...

Background: Brown tumor of bone is a non-neoplastic lesion resulting from abnormal bone metabolism in hyperparathyroidism. Brown tumor, as the only and initial symptom of normocalcemic primary hyperparathyroidism is extremely rare.Case presentation: A 69-year-old female patient was admitted to the hospital with a mass in the right thigh. A mass lesion of the right distal femur with bone and soft tissue infiltration was observed in the lower extremity mag...

Objectives: Obesity is a chronic and progressive disease that limits physical activity, causes psychological problems, and finally leads to social isolation of the person. Detecting the factors affecting obesity and its prevalence in the populaton are important steps in dealing with the problem. In this study, we aimed to evaluate the obesity prevalence and the factors affecting this prevalence in randomly selected volunteers from residents of the city of Bursa.<p class="a...

Background: Aggressive pituitary adenomas (APAs) take place phenotypically between benign pituitary adenomas and pituitary carcinomas with systemic metastasis. Frequent recurrence and resistance to conventional treatments are characteristic features of APAs in their clinical course. Temozolomide is an alkylating agent that has been used in the treatment of pituitary carcinomas and APAs since 2006. Herein, we report a patient who received temozolomide treatment due to APA.<...

Background: Because of prolong exposure to elevated endogenous growth hormone (GH) and insulin-like growth factor (IGF-1) levels in acromegaly, it is resulted in multipl comorbidities such as somatic growth, hypertension, diabetes and sleep apnea. Systemic complications caused by acromegaly include gastrointestinal (GIS) involvement. In our study it was planned to evaluate the upper GIS findings by using endoscopic and ultrasonographic methods in acromegaly patients.<p cla...

Introduction: Adrenocortical carcinoma (ACC) is a rare endocrine malignancy, with an incidence in the literature of 0.5 to 2 cases per million population per year. The most important prognostic factors are stage of cancer at the time of diagnosis and success of the first surgery. However, advanced age, tumor size, functionality, high Ki-67 index (>10%), necrosis, and high mitotic activity are among poor prognostic factors.Patients and method: Fifteen...

Introduction: Vitamin D Deficiency has been widely regarded as contributing to autoimmune disease, but low levels of vitamin D in patients with autoimmune disease may be a result rather than a cause like from malabsorbtion due to celiac disease, gastrointestinal disorders related to diabetes or thyroid disease, corticosteroid therapy complications etc\..In this study, we aimed to investigate vitamin d levels in autoimmune endocrine disorders and relationship with silent celiac...

One of the main problems encountered with increased levels of serum PTH is decrease in bone mineral density in the long term. Secondary hyperparathyroidism due to vitamin D deficiency leads to mineralization disorders of the bones, low bone mineral density, osteoporosis and ultimately an increased risk of bone fracture in adults. In this study, we aimed to determine the reasons of secondary hyperparathyroidism for bone mineral density.One hundred and thi...

In this study, we aimed to investigate the causes of elevated PTH levels in postmenopausal women without the use of drugs that may affect of PTH levels and without concomitant diseases.A total of 156 postmenopausal women, aged ≥ 50 years, had no menstruation for at least 2 years and had no disease known to affect calcium metabolism were considered. Education, occupation, average duration of exposure to sunlight per day in summer and winter, consump...
