Aim: Exophytic nodule refers to a nodule that sticks out of the normal thyroid boundary/outline. Other definition is a nodule with an acute angle between the lesion and adjacent thyroid capsule. In the literature, one study reported that thyroid nodules with exophytic configuration showed a high malignancy rate. We aimed to compare ultrasonographical features and cytopathologic results of exophytic and non-exophytic thyroid nodules.Material and method: T...

Introduction: Ocular changes and ocular symptoms may be encountered in patients with hypothyroidism and hyperthyroidism. However, the data concerning the effects of thyroid disorders on intraocular pressure (IOP), central corneal thickness (CCT), and retinal thickness (RT) are very rare. Here, we aimed to evaluate the alterations in IOP, CCT, and RT in patients with euthyroid autoimmune thyroiditis (AIT).Methods: Twenty-five subjects with euthyroid AIT w...

Introduction: Diabetes insipidus (DI) is a disease characterized by excessive thirst, polydipsia and excess diluted urine caused by insufficiency of antidiuretic hormone or renal resistance to its effect. Although it is generally a benign condition, severe hypernatremia and hypertonicity may cause death if water loss is not compensated.Case report: A 72-years-old man admitted to our clinic for routine control. In medical history, he told that when he was...

Introduction: Acromegaly is a chronic disease caused by excessive secretion of growth hormone (GH), and as a result, of insulin-like growth factor-1 (IGF1). Although controversial, frequency of both benign and malignant neoplasm formation is thought to be increased in acromegalic patients. Pleomorphic adenoma is the most common arising tumour from the parotid salivary gland. Here we report the case of a 33-year-old woman with acromegaly and also who presented with a swelling o...

Introduction: Xantoma disseminatum (XD) is a rare non-Langerhans cell histiocytosis (NLCH) which is often resistant to treatment. In this report, we presented a case with extensive cutaneous, hypothalamohypophysial, cerebral and gastrointestinal system involvement, which responded well to cyclophosphamide.Case: A 16-year-old female patient admitted to our hospital with the complaints of amenorrhoea, weight gain, polidipsia, poliuria, yellow-brownish papu...

Introduction: Leri–Weill dyschondrosteosis (LWD) is a rare autosomal dominant dyschondrosteosis characterised by Madelung deformity and mesomelic dwarfism. Majority of cases are associated with haploinsufficiency of the short-stature homeobox-containing (SHOX) gene. Here we report a patient with LWD and diabetes mellitus (DM).Case report: A 31 years old man applied with polyuria and polydipsia. He did not have any chronic disease. In family history,...

Introduction: Normal or elevated TSH level in the presence of elevated T4 is defined as ‘inappropriate TSH syndrome’. Two main clinical conditions that can lead that syndrome are TSH-secreting adenoma (TSHoma) and resistance to thyroid hormone (RTH). Making the correct diagnosis is crucial in order to decide the most appropriate treatment option. Herein we presented clinical and laboratory data of seven patients who were hospitalised for the differential d...

Aim: Vitamin D deficiency is reported as a risk factor for the development of diabetes in several epidemiologic studies. In this study, we investigated the frequency of 25-OH vitamin D deficiency in type 2 diabetes and the relationship between 25-OH vitamin D deficiency and microvascular complications.Materials and methods: Retrospectively, medical records of 557 type 2 diabetic patients admitted to the Endocrinology Outpatient Clinic in January–Mar...

Case: A 30-year-old man with hypoparathyroidism has been treated with calcitriol and calcium for 2 years, admitted hospital with persisting diarrhea. An endoscopic operation is planned. But when he was waiting for this examination as outpatient condition, he had a convulsion and had been taken in hospital by parents. Initial laboratory analyses revealed that he was hypocalcemic (total calcium of 6 mg/dl) and parathormone (PTH) 8 pg/ml, phosphorus 5.7 mg/dl, and magnesium 2 mg/...

Introduction: Major factor that modulates the PTH secretion is serum Ca level. Paratyhyroid gland also receives direct autonomic innervation. To date, measurement of several hormones such as cortisol,prolactin, renin and aldosteron were found to be affected by changing the posture from recumbent to the upright position. In the present study, we aimed to investigate postural change of PTH in normal individuals and patients with primary hyperparathyroidism (PHPT).<p class="a...
