Von Hippel-Lindau (VHL) syndrome is a pathological condition that causes various clinical symptoms and is difficult to diagnose. The most common pathological lesions are hemangioblastomas of the central nervous system, retinal angiomas, renal clear cell carcinomas, and pheochromocytomas. Here we reposrt a case of likely to be VHL due to his family history.Case: A 33-year-old male suffering from hypertension and a history of hemangioblastoma operated in 2...

Introduction: Malignant struma ovari is a rare ovarian mature teratoma. The diagnosis can be done histopathologically. There are no specific diagnostic findings in terms of imaging, clinical and laboratory. We present two cases of malignant struma ovarii in papillary follicular variant subtypes in this report.Case report: Case 1; The patient was a 44 year old female, she had complaints of pelvic pain and a palpable lower abdominal mass. Pelvic MRI examin...

Thyroid cancer is the most common malignancy of the endocrine system. Papillary thyroid cancer is the most common thyroid malignancy worldwide and has a good prognosis. The prevalence of follicular thyroid cancer in endemic iodine deficiency regions is higher than in regions without iodine deficiency. However, it has been observed that the incidence of follicular thyroid cancer decreases and the incidence of papillary thyroid cancer increases after iodine prophylaxis. The Our ...

Objective: To determine whether relationship between trace element levels and microvascular complications of type 2 Diabetes Mellitus (T2DM).Methods: One hundred eighteen patients with type 2 DM (mean age: 56±6.2 years) and 40 control subjects (mean age: 40.0±8.8 years) were included in the study. Group 1 (n=40 patients) was composed of patients with no had microvascular complications and it divided into two subgroup, first subgroup (<...

Aim: İmpaired glucose tolerance and hyperinsulinism/insulin resistance frequently accompany by acromegaly. NLO (Neutrophile lymphocyte ratio) is demonstrated as a simple indicator of systemic inflammation and it is also known that NLO is associated with atherosclerosis progression in coronary artery and a risk factor in coroner artery disease. In this study, we intend to search the association between both coronary atherosclerosis seen frequently in patients diagnosed wi...

Introduction: The Sodium Iodide Symporter (NIS) is responsible for active transport of iodide into thyroid follicular cells, enabling the use of radioactive iodine (RAI) for treatment of metastatic disease. Still, a significant proportion of patients with advanced forms of thyroid cancer (TC) became refractory to RAI therapy. Defective NIS expression is the main reason for impaired iodide uptake in TC and NIS downregulation has been associated with several pathways linked to m...

Introduction: Patients with Down syndrome are vulnerable to autoimmune thyroid disease and progression from Graves’ disease (GD) to Hashimoto’ thyroiditis or vice-versa may be more frequently seen in this population, specially at a younger age. In the last years questions have been raised regarding the distinction of this metamorphic scenario from a single entity: autoimmune thyroiditis with TRAbs that trigger opposite functional actions.Case...

Thyroid hormone has long been known as a key developmental factor in human and model species. Insufficient thyroid hormone during development can impair the growth and maturation of diverse tissue and organ systems. One of the most serious risks associated with congenital hypothyroidism is defective brain maturation and mental retardation. However, in recent years, targeted mutagenesis of the thyroid hormone receptor genes in model species has expanded our understanding of the...

Background: Pregnancy alters the natural history of autoimmune thyroid disorders. The incidence rate of positive thyroid antibodies (T-abs +) in asymptomatic women during pregnancy has been reported to be between 6 and 19.6%.Aim: To determine the prevalence of thyroid antibodies (T-abs) in Gestational Diabetes Mellitus (GDM).Subjects & Method: In 408 women, at the time of diagnose of GDM, TSH, free thyroxine, free tri-iodothyro...

Introduction: Bartter syndrome represents a set of closely related autosomal recessive renal tubular disorders characterised by hypokalemia, hypochloremia, metabolic alkalosis and hyperreninemia with normal blood pressure. The underlying abnormality results in excessive urinary losses of sodium, chloride and potassium. Bartter syndrome is classified into 3 main clinical variants: neonatal Bartter syndrome, classic syndrome and Gitelman syndrome.Case repo...
