Is any body composition parameter a risk factor for symptomatic hypocalcemia after thyroidectomy?

Celik Suleyman Utku , Akkan Tolga , Konca Can , Genc Volkan

Objective: Postoperative hypocalcemia is one of the major concerns following total thyroidectomy as well as the most frequent cause of prolonged hospital stay. The first purpose of this study was to evaluate the relationship between body composition parameters and symptomatic hypocalcemia following total thyroidectomy. In addition, the effects of disease- and patient-related factors on hypocalcemia were investigated.Methods: In this cohort study, a total...

Two cases with metastatic thyroid cancer

Dagdeviren Murat , Altay Mustafa , Safak Ozge , Akkan Tolga

Although the thyroid gland has an abundant blood supply, metastasis to the thyroid gland is a rare condition. Its incidence varies from 0.1% and 3% in clinical series. First case. A 56-year-old man presented to emergency service with neurological symptoms. CT of brain revealed multiple hyperdens lesions. Posteroanterior chest X-ray showed increased opacity in the left lung. Metastatic lung cancer was considered as a preliminary diagnosis and PET/CT was performed. PET/CT showed...

A new and effective treatment option for challenging chronic hypoparathyroidism cases: Alternate-day dosing regimen

Akkan Tolga , Dagdeviren Murat , Or Koca Arzu , Ertugrul Derun Taner , Altay Mustafa

Objective: In chronic hypoparathyroidism, conventional therapy consists of oral calcium supplements and active vitamin D analogs but some patients cannot achieve treatment goals despite the high dose of oral calcium supplementation. Therefore, parathyroid gland transplantation and recombinant human PTH have been investigating as new therapeutic options. Calcium absorption from intestinal cells occurs by transcellular path and paracellular path. Transcellular absorption occurs ...

Nonfunctional adrenal incidentaloma affects central blood pressures and arterial stiffness parameters

Akkan Tolga , Altay Mustafa , Unsal Yasemin Aydogan , Dagdeviren Murat , Beyan Esin

Introduction: In recent years, it is thought that cardiovascular risk is increased in patients with nonfunctional adrenal insidentaloma (NFAI). There are not enough studies in the literature that evaluating this condition in patients with NFAI who don’t have traditional cardiovascular risk factors. The aim of our study is to determine peripheral and central blood pressures and arterial stiffness in patients with NFAI who don’t have traditional risk factors and autono...

Is there any relationship between nonfunctional pituitary adenoma and arterial stiffness?

Cagir Yavuz , Altay Mustafa , Cakal Erman , Cagir Busra Betul , Akkan Tolga , Dagdeviren Murat , Beyan Esin

Introduction: In a recent study, it was determined that morbidity rates due to cardiovascular diseases were affected as a result of long-term follow-up in patients with nonfunctional pituitary adenoma. And cardio/cerebro vascular diseases were the most frequent cause of mortality when mortality rates were examined. In the literature, there are not enough studies evaluating this condition in patients with nonfunctional pituitary adenoma without traditional cardiovascular risk f...

Neutrophil/lymphocyte (N/L) ratio should not be used as an indicator of inflammation in hyperthyroid patients

Dagdeviren Murat , Akkan Tolga , Celiker Dilek , Karakaya Serdar , Ertugrul Derun Taner , Altay Mustafa

Introduction: Neutrophil/lymphocyte (N/L) ratio is considered as a sign of systemic inflammation in recent years. In our study, we aimed to investigate N/L ratio in hyperthyroid patients and healthy control group.Material & methods: A total of 121 hyperthyroid patients (71 patients with Graves’ disease and 50 patients with other causes of hyperthyroidism) and 40 healthy volunteers were enrolled. Complete blood count was obtained from both group ...

Arterial stiffness in hyperthyroid patients is deteriorated due to thyroid hormones

Yildiz Canan , Altay Mustafa , Yildiz Sedat , Cagir Yavuz , Akkan Tolga , Unsal Yasemin Aydogan , Beyan Esin

Aim: It is aimed to evaluate whether arterial stiffness, which is an independent risk indicator for hyperthyroid cardiovascular diseases, is affected by pulse wave analysis (PWA) and to observe changes in patients treated with hyperthyroidism.Methods: A total of 102 volunteers were included in the study (30 in the overt hyperthyroid group, 28 in the subclinical hyperthyroid group and 14 with euthyroidism by antithyroid therapy and 30 healthy). The arteri...

Evaluation of oxidative stress parameters in subacute thyroiditis patients

Dağdeviren Murat , Koca Arzu Or , Akkan Tolga , Ateş İhsan , Neşelioğlu Salim , Erel Ozcan , Altay Mustafa

Objective: The aim of our study was to determine whether there is a relationship between oxidative stress parameters and subacute thyroiditis.Material and methods: The study included 55 subacute thyroiditis patients and 30 healthy volunteers. Total antioxidant status (TAS), total oxidant status (TOS), paraoxonase (PON) and thiol/disulfide homeostasis parameters were measured by a novel and automated assay in the patient and control groups.<p class="a...
