BACKGROUND/OBJECTIVE Artificial sweeteners were thought to be metabolically inactive, but after demonstrating that the gustatory mechanism was also localized in the small intestine, suspicions about the metabolic effects of artificial sweeteners have emerged. The objective of this study was to determine the effect of artificial sweeteners (aspartame and(More)
OBJECTIVE To investigate whether thyroid function in the euthyroid range and thyroid autoimmunity status would affect metabolic measures in individuals with obesity. DESIGN Cross-sectional. PATIENTS We retrospectively evaluated 5300 consecutive obese (BMI ≥30 kg/m(2) ) subjects attending the Obesity Outpatient Clinic. Subjects with overt or subclinical(More)
Prolactin (PRL) may have stimulatory effects on vascular resistance. We aimed to analyze uterine, spiral, and intraovarian artery blood flow by Doppler ultrasonography in hyperprolactinemic patients prior to and after treatment with cabergoline. The study was conducted in Sisli Etfal Training and Research Hospital gynecology outpatient clinic between 1(More)
OBJECTIVE To determine whether insulin resistance (IR) accompanies normocalcemic primary hyperparathyroidism (NCPHP). METHODS Twenty-five patients with NCPHP and 25 age-, sex-, and body mass index (BMI)-matched controls were included the study. Patients were diagnosed NCPHP if their serum calcium (Ca) concentrations and ionized serum Ca levels were in the(More)
OBJECTIVE To investigate whether soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) levels are increased in euthyroid patients with Hashimoto's thyroiditis (HT) and whether they are associated with thyroid autoimmunity and metabolic parameters. DESIGN Cross-sectional. SUBJECTS AND METHODS In(More)
Paragangliomas of the head and neck are uncommon neoplasms. They are usually benign, but tend to be locally invasive. Although surgical resection remains the definitive treatment, important issues about management arise when such lesions are inoperable. Beneficial effects of octreotide treatment have already been reported in a malign paraganglioma case.(More)
Background. Our aim was to define the conditions that affect therapeutic success when dipeptidyl peptidase-4 (DPP-4) inhibitor is added to metformin monotherapy. Materials and Methods. We reviewed the medical records of 56 patients who had received DPP-4 inhibitor as an add-on to metformin monotherapy and evaluated their response in the first year of(More)
Behçet's disease (BD) may affect female reproductive vasculature. We aimed to evaluate Doppler sonographic characteristics of female reproductive vasculature and also ovarian volume, endometrial thickness (EMT) and antral follicle count of BD patients in comparison with a healthy control group. Seventeen premenopausal women aged between 18-45 years with BD,(More)
The prognostic importance of 18F-fluorodeoxyglucose avidity in primary thyroid tumor and molecular basis responsible for its mechanism has not yet been well characterized. In this study, we aimed to evaluate the correlation between the maximum standardized uptake levels and B-type Raf kinase mutation positivity in incidentally detected papillary thyroid(More)
UNLABELLED Madelung's disease is a rare fat metabolism disorder characterised by benign multiple symmetric, encapsulated lipomatosis. The exact cause of the disease is unknown; it may be associated with chronic alcoholism and mutations in mitochondrial DNA (A8344G), but there have been cases without these factors reported in the literature. A 29-year-old(More)
