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...

Introduction: Vitamin D deficiency has become a major public health problem. It’s known that the effects of vitamin D are made by its receptors. VDR gene polymorphisms in susceptibility to different diseases demonstrated in many studies. The polymorphisms of VDR are ApaI, TaqI, FokI, and BsmI. BsmI is the most extensively studied polymorphism. In our study, the aim is to show the frequency of VDR BsmI gene polymorphisms and to show the relationship between polymorphisms a...

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...

Introduction: Adrenal failure due to tuberculosis is rarely seen nowadays. There are few reports in the literature suggesting that adrenal insufficiency may improve with anti-tuberculosis therapy during the active phase of the disease. Herein, we presented a case of reversible adrenal failure in a patient with active tuberculosis.Case report: A 50-years-old-female patient admitted to our clinics with the complaints of weakness and darkening of the skin. ...

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...

Background: Diabetic retinopathy (DR) is the leading cause of blindness in the world. Retinopathy and nephropathy can still progress in diabetics despite optimal metabolic control. The aim of the present study was to determine whether different degrees of DR (proliferative or non-proliferative) were associated with abnormally modulated hemostatic parameters in patients with type 1 DM.Method: 52 type 1 diabetic patients and 40 healthy controls were enroll...

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...

Introduction: Hypoglycemia is common in people with diabetes who aim to achieve strict glucose control. The neurologic manifestations of hypoglycemia are mostly reversible and includes behavioral changes, difficulty in concentration, confusion, loss of fine motor functions, and seizures. Herein we have presented a case who was pregnant and experienced severe hypoglycemia which led to permanent ataxia.Case: A 26-years-old female patient was brought to our...

Background: PCOS is one of the most common disorders affecting at least 5–10% of women of reproductive age. Increased prevalance of autoimmune thyroiditis and goiter were reported in PCOS patients. This study investigated the prevalance of hypothyroidism, thyroid autoimmunity, ultrasonographic features and presence of nodules in PCOS patients and compare them with the control group. We also aimed to detect correlation of thyroid volume (TV) with serum IGF1 levels in patie...
