Introduction: Endocrinological and metabolic changes can occur in critically ill patients, which may affect the prognosis and outcome. The hypothalamic–anterior–pituitary axis (HPA) plays a crucial role in the endocrine regulation of metabolic and immunological homeostasis. In this prospective study, we evaluated the pituitary–adrenal–gonadal–thyroid axis in the adult Intensive Care Unit (ICU) patients,their outcome, the association between these hormo...

Aim: It is well known that there is a strong relationship between chronic inflammation and tumorigenic process. The cytological diagnosis of follicular neoplasm (FN) carries a 20–30% risk of malignancy for thyroid nodules. In this study, we aimed to evaluate whether preoperative neutrophil to lymphocyte ratio (NLR) is a predictive factor for malignancy in thyroid nodules diagnosed as FN on cytology.Materials and methods: A total of 139 patients with...

Introduction: The risk of malignancy has often been reported to be more frequent in Graves’ disease (GD) than non-autoimmune thyroid nodules. However, frequency of thyroid nodules, diagnostic yield of fine-needle aspiration (FNA), and their potential for bearing malignancy in GD are still debatable issues. We aimed to determine the prevalence, ultrasonographic and cytological features, and the rate of malignancy outcome of thyroid nodules in a group of patients with GD.</...

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: 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...

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...

Addison’s disease (AD), is an autoimmune disorder. However, its association with connective tissue diseases is rare. Here, we report a case of AD associated with ankylosing spondylitis (AS).Case: A 57-year-old male patient admitted to internal medicine polyclinic with complaints of debility and anorexia. In the physical examination, he has hyperpigmentation on his skin, gingiva and palm lines. Blood pressure was 80/50 mmHg, pulse was 64/min. The oth...

Introduction: Viruses and virus-induced lymphokines may have an important role in the pathogenesis of autoimmunity. The occurrence and significance of autoimmune manifestations after the administration of viral vaccines remain controversial. Herein we have represented a case who developed type 1 diabetes 1 month after vaccination for measles in military.Case: A 25-year-old male patient admitted to our clinics with the complaints of polyuria, poydipsia, a...

Introduction: Diabetic nephropathy (DN) is an important one of the complications and is detected in almost 30-40% of the patients with type 1 diabetes mellitus (T1DM). Besides the well known risk factors, endothelial dysfunction also plays a role in the pathogenesis of DN and diabetic retinopathy. Our aim was to determine flow mediated dilation measurements and serum soluable ET-1, ICAM-1, and VCAM-1 levels in T1DM patients with or without inceased albumin excretion and compar...
