ObjectiveScanty data about glucose metabolism, hypertension and metabolic syndrome (MS) have been reported in Paget’s disease of bone (PDB) to be related with increased cardiovascular mortality. We aimed to determine prevalence of metabolic syndrome in PDB and to determine the relationship between metabolic syndrome and bone-specific alkaline phosphatase levels.Patients and methodsTwenty three patients w...

Aim: Metabolic syndrome rates have been studied especially in adrenal gland secreting cortisol and studies on nonfunctional adenomas are limited. In this study, we investigated metabolic parameters and metabolic syndrome frequency in non-functional adrenal adenomas (NFA).Materials and methods: In our study, 55 patients (15 men (27.3%), 40 women (72.7%) who were diagnosed incidentally, unilateral or bilateral localized, hormone-inactive, and with adenoma-...

Introduction: Hyperkalemia due to zona glomerulosa (ZG) insufficiency is generally transient and mild for patients with aldosterone-producing adenoma (APA) after adrenalectomy. We report here a case with prolonged ZG insuffiency requiring long-term mineralocorticoid replacement (MR) therapy.Case report: A 45-years-old female with hypertension and hypokalemia admitted to outpatient clinic with incidentally detected right adrenal adenoma (3 cm) showing sig...

Introduction: Hypogonadism persisting in man with macroprolactinoma requires exogenous testosterone replacement therapy (TRT). But TRT may cause secondary elevations of prolactin. We report here a case of macroprolactinoma and hypogonadotropic hypogonadism with persistently high prolactin level after initiating TRT.Case report: A 28 year-old male was admitted to outpatient clinic with complaints of headache, low libido and blurred vision on left eye for ...

Purpose: To determine the relationship between grade of diabetic retinopathy and serum vitamin D levels in diabetic patients.Materials and methods: A total of 173 diabetic patients consisting of patients without retinopathy (n=67), patients with non proliferative diabetic retinopathy (NPDRP group n=47), patients with proliferative diabetic retinopathy (PDRP group n=59) was included in the study. Age and sex matched 55 healthy s...

Introduction: Ectopic ACTH syndrome (EAS) is a rare cause of Cushing’s syndrome. EAS is most frequently caused by bronchial carcinoid tumor or small cell lung cancer. Medullary thyroid carcinoma (MTC) is a rare source of EAS, as reported in this case.Case report: A 65-years-old-female with back pain and weight gain referred to our outpatient clinic with determined signs and symptoms of hypercortisolism. She had arterial hypertension, her sister had ...

Introduction: Cushing’s disease (CD) frequently leads to hypogonadotropic hypogonadism by hypercortisolism and hyperandrogenemia. In the literature, there are totally 96 cases of CD and pregnancy. Only four of 11 cases, operated transsphenoidally, were cured. We aimed to present a case of CD developing pregnancy in which hypercortisolism was successfully controlled by transsphenoidal surgery (TSS) in 2nd trimester.Case report: 28 years old female wa...

Introduction: Maturity-onset diabetes of young (MODY) type 2 is caused by mutation of the glucokinase gene. It is characterized by mild fasting hyperglicemia and absence of vascular complications. It is estimated that the incidence of gestational diabetes is 3%. We aimed to present a pregestational diabetic case with MODY-type 2 in pregnancy.Case report: A 38-year-old pregnant woman was referred to our clinic for glycemic regulation at 22th week of gesta...

Introduction: Autoimmune polyendocrine syndromes (APS) are rare endocrinopathies characterized by the coexistence of at least two glandular autoimmune diseases. APS comprise a wide spectrum of autoimmune disorders and are divided into a very rare juvenile (APS type 1) and a more common adult type with (APS 2) or without adrenal failure (APS 3). We present a patient with polyglanduler syndrome type 3a.Case report: A 39-years-old female patient was present...

ObjectiveIn patients with Cushing’s disease (CD), normal pituitary corticotrophs are suppressed by excessive and persistent cortisol secretion in responce to autonomous ACTH secretion by tumour. Therefore, patients exhibit signs and symptoms of ACTH deficiency shortly after resection of tumour and need steroid replacement therapy (SRT) until hypotalamo-pituitary-adrenal (HPA) axis recovery. We aimed to evaluate whether duration of SRT can serve as a...
