Purpose: Previous studies have pointed to the role of parathormone (PTH) in the development of simple renal cysts. However, there is insufficient evidence related to simple renal cysts in primary hyperparathyroidism (PHPT). Therefore, this study aimed to evaluate the prevalence and risk factors associated with renal cysts in PHPT patients.

Fatty acid-binding protein-4 as a biomarker predicting acromegaly-associated diabetes mellitus.

Background: The known pathogenesis of diabetes mellitus (DM) in acromegaly is mainly based on growth hormone (GH) and insulin-like growth factor-1 (IGF-1) excess. Fatty acid-binding protein 4 (FABP-4), a novel adipokine, is found to induce insulin resistance and type 2 DM. We aimed to investigate the possible effect of FABP-4 on glucose metabolism in patients with acromegaly.

The Importance of Vitamin D Level in Subacute Thyroiditis Disease and the Effect of Vitamin D on Disease Prognosis.

Objective: Subacute thyroiditis (SAT) is an inflammatory thyroid disease that manifests with severe pain. The presence of the vitamin D receptor in immune system cells shows that vitamin D deficiency can trigger inflammatory diseases. The aim of the present study was to determine the prevalence of vitamin D deficiency in SAT patients, and the relationship between vitamin D level and permanent hypothyroidism and recurrence rate.

The contribution of ultrasonographic findings to the prognosis of subacute thyroiditis.

Objective: Ultrasound assessment plays an important role in the diagnosis, and monitoring of subacute thyroiditis (SAT). However, the relationship between ultrasonographic findings and severity or prognosis of the disease is not known. The aim of the present study was to evaluate the relationship between bilateral and unilateral disease involvement and severity and prognosis of the disease.

Preoperative Vitamin D Levels as a Predictor of Transient Hypocalcemia and Hypoparathyroidism After Parathyroidectomy.

Hypocalcemia is a common problem after parathyroidectomy and/or thyroidectomy. The complication may be transient or permanent. Most cases occur as a result of removal of the parathyroid glands or damage to the glands during neck surgery.

The effects of patient and disease-related factors on the quality of life in patients with hypoparathyroidism.

Unlabelled: This study aims to evaluate factors affecting the quality of life (QOL) of hypoparathyroidism. While QOL is reduced in post-surgical and non-surgical groups, mental health seems to be less affected in non-surgical patients. Having an additional disease affects QOL negatively but having thyroid cancer may not change the QOL results.

Serum cortisol level after low dose dexamethasone suppression test may be predictive for diabetes mellitus and hypertension presence in obese patients: A retrospective study.

Aims: Obesity, a remarkably increased healthcare problem, accompanies with morbidities including type 2 diabetes mellitus (DM), hypertension, and cardiovascular diseases. Hypothalamic-pituitary-adrenal (HPA) axis alteration is thought to be effective on the background of obesity, even concomitant with DM and hypertension. We aimed to evaluate the negative feedback mechanism of the HPA axis via overnight 1 mg dexamethasone suppression test (DST) and the association of post-1 mg DST cortisol level with DM and hypertension presence in obesity.

The Effect of Exenatide on Thyroid-Stimulating Hormone and Thyroid Volume.

Objective: Glucagon-like peptide-1 (GLP-1) analogues are now widely used for the treatment of type 2 diabetes mellitus (DM). Many binding sites for GLP-1 have been demonstrated in the specific tissue compartments of organs in-cluding the brain and thyroid. The aim of this study was to investigate the effect of exenatide treatment on thyroid-stimulating hormone (TSH) and thyroid volume in diabetic patients without thyroid disease.

The prognostic and diagnostic use of hematological parameters in subacute thyroiditis patients.

Background: Subacute thyroiditis (SAT) is an acute inflammatory disease of the thyroid. Mean platelet volume (MPV), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) values determined from peripheral blood, are accepted as available and practical indicators of systemic inflammation. The purpose of this study was to evaluate the value of hematological parameters in the diagnosis and prognosis of subacute thyroiditis patients.

Soluble Tumor Necrosis Factor (TNF)-Like Weak Inducer of Apoptosis (Tweak) Independently Predicts Subclinical Atherosclerosis in Behcet's Disease.

Background: Vasculopathy is a major cause of mortality and morbidity in Behcet's Disease (BD). Subclinical atherosclerosis can even be detected in the early stage of BD.

Atherogenic index of plasma: a useful marker for subclinical atherosclerosis in ankylosing spondylitis : AIP associate with cIMT in AS.

Ankylosing spondylitis (AS) is associated with an increased risk of atherosclerotic cardiovascular disease (ACD). The atherogenic index of plasma (AIP), which is the logarithmic transformation of the plasma triglyceride (TG) level to the high-density lipoprotein level (HDL) ratio, has been suggested to be a novel marker in the identification of atherosclerosis risk. Therefore, this study aims to determine if the AIP can act as an accurate marker for the detection of subclinical atherosclerosis.

Plasma Atherogenic Index is an Independent Indicator of Subclinical Atherosclerosis in Systemic Lupus Erythematosus.

Objective: Systemic lupus erythematosus (SLE) is characterized by chronic inflammation. Plasma atherogenic index (PAI) is a valuable marker for the cardiovascular disease and cardiac risk. The aim of this study was to evaluate the role and clinical use of PAI in atherosclerosis and the cardiac risk in SLE patients.

The Relationship Between Atherogenic Index and Carotid Artery Atherosclerosis in Familial Mediterranean Fever.

Familial Mediterranean fever (FMF) is a disease characterized by chronic inflammation. Atherogenic index of plasma (AIP) is a logarithmic value of the triglyceride to high-density lipoprotein cholesterol ratio and it is a good marker for atherosclerotic heart disease and cardiac risk. In this study, we investigated subclinical atherosclerosis and cardiac risks in patients with FMF.
