Cystic parathyroid adenomas: ultrasonography features

Karbek Basak , Karakose Melia , Caliskan Mustafa , Bozkurt Nujen Colak , Aslan Muyesser Sayki , Delibasi Tuncay

Introduction: Parathyroid adenomas appear typically as homogeneous, hypoechoic lesions compared to the thyroid on the ultrasonography examination. They can be detected easily when they are more than 1 cm. However, cystic parathyroid adenomas are rare. When present, they appear as decreased echogenic areas in the gland. Extrathyroidal feeding from an artery at one pole of the gland is characteristic which is seen on Doppler imaging. We aimed to present a case series including s...

İntroduction: Polycystic ovary syndrome (PCOS) is associated with risk of cardiovascular disease (CVD). Endocan is potential immunoinflammatory and endothelial dysfunction marker that may be linked to CVD. This study aimed to evaluate the risk of CVD in PCOS patients and to identify the novel biomarker for CVD risk.Material and methods: We analyzed 52 premenopausal women with PCOS and 59 healthy controls. Clinical, biochemical parameters and endoca...

Introduction: Vitamin D deficiency is a common health problem. Vitamin D supplements are used to improve vitamin D status. However, there are few data about what doses to give and how often to give. The aim of this study is to determine the effects of single high dose or daily low dose oral cholecalciferol (vitamin D3) on vitamin D levels and muscle strenght.Methods and design: 60 healthy postmenouposal women who had serum vitamin D levels wer...

Introduction: Hypopituitarism is commonly acquired in adult life and its main causes are pituitary tumors and/or their treatments, empty sella syndrome and etc.Patients and methods: A double centre, cross-sectional database study was performed in Turkish population for last 10 years to investigate the etiology of hypopituitarism. One-hundred forty nine patients were included (53% female and 47% male) with a mean age of 47.9±15.6 years (ranging from ...

Demirci Taner , Uyar Mehmet , Catalli Emel Tatar , Caliskan Mustafa , Ucan Bekir , Demiral Dilek , Arslan Muyesser Sayki , Ozbek Mustafa , Korkmaz Mehmet Hakan , Delibasi Tuncay

Introduction: The relationship between hyperthyroidism and voice disorders has not been identified before. The aim of this study was to investigate the changes in the acoustic values in patients with subclinical thyrotoxicosis.Methods: In this study, acoustic voice analysis was evaluated in a total of 115 cases. Sixty of 115 individuals (18 men and 42 women) had subclinical thyrotoxicosis, aged between 18 and 65 years, and all had no history of laryngeal...

Apaydin Mahmut , Beysel Selvihan , Kan Seyfullah , Ucan Bekir , Tutal Esra , Demirci Taner , Caliskan Mustafa , Kizilgul Muhammed , Ozbek Mustafa , Cakal Erman , Delibasi Tuncay

Introduction: Levothyroxine sodium (LT4) is widely used thyroid hormone to treat hypothyroidism. It is generally recommended to take it in the morning and hungry. Several studies about timing of thyroid hormone administration have shown different effects on TSH and FT4. The aim of this study is to determine the effects of timing of LT4 administration on TSH and the clinical outcomes.Method: The study group includes 65 pat...

Aims: Primary hyperparathyroidism (PH) has been reported to be associated with increased insulin resistance, hypertension, dyslipidemia and cardiovascular inflammatory markers. The aims of this study were to evaluate the rate of metabolic syndrome (MS) and effect of parathormone, calcium and phosphorus levels to MS components in PH subjects.Methods: One hundred and fifty one subjects, 23 men and 128 women, aged 53±11.2 years with newly diagnosed PH ...

Cervical paraganglioma ultrasonographically mimicking parathyroid adenoma: a case report

Beysel Selvihan , Caliskan Mustafa , Arslan Muyesser Sayki , Karakose Melia , Tutal Esra , Kan Seyfullah , Kizilgul Muhammed , Apaydin Mahmut , Cakal Erman , Ozbek Mustafa , Delibasi Tuncay

Introduction: Paragangliomas are neuroendocrine tumors arising from extra-adrenal chromaffin cells. Paragangliomas of the head and neck frequently originate from the paraganglionic system including the carotid bifurcation, middle ear and the ganglion nodosum of the vagus nerve. However, of paragangliomas of the head and neck, only 1–3% secrete hormones and majority are non-functional. Here, we describe a case of non-functional paraganglioma confused with parathyroid adeno...

Introduction: While mediastinal parathyroid carcinoma is a rare entity by itself, multiglandular coexistence of parathyroid carcinoma and adenoma represents an extremely rare condition. Herein, we report such a rare presentation of multiglandular parathyroid neoplasm with an ectopic carcinoma in the mediastinum and adenoma on the right side of neck in a patient with persistent primary hyperparathyroidism (PHP).Case report: A 38-year-old female patient wh...

Aim: Overt hypothyroidism affects mostly women with an increased prevalence in individuals by age. Hypothyroidism is associated with accelerated atherosclerotic cardiovascular diseases, possibly caused by the higher incidence of hyperlipidemia, insulin resistance, hypertension which all are associated to hypothyroidism. Heart-type fatty acid binding protein (H-FABP) is specific for cardiomyocytes and a sensitive marker of myocardial injury. The purpose of this study is examini...
