Objective: Platelet activation is a recently recognized characteristic of prolactin, which functions through the potentiation of ADP-induced P-selectin expression on platelets. Studies in hyperprolactinemic patients demonstrated atherosclerotic disorders related to insulin resistance; convenient milieus for platelet activation. To investigate the association between hyperprolactinemia and platelet activation related to P-selectin expression, we studied on hyperprolactinemic an...

To asses the presence of antibodies to BIP/GRP78, which is a chaperon of endoplasmic reticulum and has immune modulating and antiapoptotic effects in Hashimoto’s thyroiditis.The study included 62 patients with autoimmune thyroiditis. Of these, 20 had euthyroid, 27 had subclinical hypothyroid, and 15 had hypothyroid Hashimato’s thyroiditis. A control group including 37 healthy patients also participated in the study.There ...

Objective: Our aim was to determine the prevalence and clinicopathological characteristics of thyroid cancers in the dialysis population and to evaluate potential risk factors.Design: We performed a retrospective analysis of our end-stage renal disease (ESRD) patients on dialysis and thyroidectomized patients without ESRD (2000–2006). Then we compared the data of thyroid cancer patients on dialysis (n=9) with the data of patients who had hist...

Objective: Approximately 30% of patients with thyroid nodules have indeterminate, nondiagnostic, or suspicious fine-needle aspiration (FNA) biopsy results. These patients usually undergo thyroidectomy because of cancer risk. Our aim was to determine diagnostic markers to distinguish benign from malignant thyroid neoplasms, so we focused on G2-M boundary regulators of the cell cycle and investigated the expression of two proteins, cyclin A and cyclin B1.M...

Objective: The thiazolidinediones are new and potentially useful developments in the treatment of type 2 diabetes and impaired glucose tolerance. We tested the effects of the thiazolidinedione, rosiglitazone on blood pressure in normotensive type 2 diabetes.Methods: After receiving approval from the local ethics committee, 25 normotensive diabetic patients were were enrolled to the study. Before the rosiglitazone treatment we measured plasma glucose, HbA...

Objective: Thiazolidinediones (TZDs) have become a powerful tool for lowering insulin resistance. The problem of cardiovascular adverse events including fluid retention and risk of heart failure, although of a low incidence, should be well known and recognized. We aimed to evaluate the effects of rosiglitazone treatment on cardiac function and show whether these effects are reversible when we continued this treatment.Methods: Fourty-six type 2 diabetic p...

The aim of this study was to compare the efficacy of treatment with insulin alone, insulin plus acarbose, insulin plus metformin or insulin plus rosiglitazone in type 2 diabetic subjects who were previously on insulin monotherapy, and to evaluate the effects of these treatments on cardiovascular risk factors including lipid profile, C-reactive protein (CRP) and fibrinogen. Sixty-six poorly controlled type 2 diabetic patients on insulin monotherapy were involved. They were rand...

There are limited data inquiring the relationship between somatostatin analogues and insulin sensitivity among acromegalic cases. This study was conducted to evaluate short-term effects of lanreotide autogel (LA), administered every 28 days by deep subcutaneous injection, on insulin sensitivity among acromegalic patients with pituitary tumors. Before and following six months of LA treatment, insulin resistance and beta-cell function were calculated by using homeostasis model a...

Pain is one of the few drawbacks of fine-needle aspiration biopsy (FNAB) in patients with nodular thyroid disease (NTD). Lidocaine/prilocaine cream, an eutectic mixture of local anesthetics (EMLA), is a frequently used topical anesthetic. Despite its well-documented efficacy for the relief of pain associated with other cutaneous procedures that involve needle insertion, the analgesic role of EMLA has not been previously reported in patients with NTD who are undergoing FNAB. Th...

Objective: Amiodarone-induced thyrotoxicosis (AIT) is usually classified into 2 types (type 1, in which a high iodine content triggers the autonomous production of thyroid hormone; and type 2, in which destructive thyroiditis causes the release of preformed thyroid hormone). A mixed form of AIT has also been also described. AIT is a difficult management problem that sometimes requires ablative thyroid therapy. The use of radioactive iodine (RAI) therapy in patients with type 1...
