Successful localisation of recurrent thyroid cancer using preoperative patent blue dye injection.

Purpose: In the follow-up of patients with thyroid cancer, recurrences are often detected, posing challenges in locating and removing these lesions in a reoperative setting. This study aimed to assess the effectiveness of preoperative ultrasound (US)-guided injection of patent blue (PB) dye into the recurrences to aid in their safe and efficient removal.

Methods: In this retrospective analysis, we reviewed the records of the patients in a tertiary care centre between February 2019 and March 2023 who underwent US-guided PB injection in the endocrinology outpatient clinic before reoperative neck surgery.

Incidental thyroid nodules on COVID-19-related thoracic tomography scans: a giant cohort.

Introduction: Computerized thoracic tomography (CT) imaging was extensively employed, especially in the early months of the COVID-19 pandemic. An incidental thyroid nodule (ITN) is defined as a nodule not previously detected or suspected clinically but identified via an imaging study. The present study aimed to determine the incidence of thyroid nodules incidentally detected in thoracic CTs for the suspicion of COVID-19 pneumonia.

Investigation of pre-operative demographic, biochemical, sonographic and cytopathological findings in low-risk thyroid neoplasms.

Objective: The present article analyses pre-operative demographic, biochemical, sonographic and histopathological characteristics of low-risk thyroid neoplasms (LRTNs), with a focus on four subgroups, "well-differentiated carcinoma-not otherwise specified" (WDC-NOS), "non-invasive follicular thyroid neoplasm with papillary like nuclear features" (NIFTP), "well-differentiated tumours of uncertain malignant potential" (WDT-UMP) and "follicular tumour of uncertain malignant potential" (FT-UMP).

Methods: The study retrospectively analyzed the histopathology of 2453 malignant thyroids and the final analyses included 99 cases diagnosed with LRTNs. The demographic and clinical features, pre-operative thyroid function, ultrasonography results, cytopathology results, histopathology results and prognostic classifications were assessed.

Paradoxical GH increase during oral glucose load may predict overall remission in acromegalic patients.

Background: The nadir growth hormone (nGH) during the oral glucose tolerance test (OGTT) is the gold standard method for diagnosing acromegaly. A paradoxical growth hormone (GH) response to oral glucose (OG) in acromegaly can be observed. The role of the paradoxical GH response on how the patients with acromegaly respond to the treatment has been addressed in few studies.

Biochemical characteristics and calcium and PTH levels of patients with high normal and elevated serum 25(OH)D levels in Turkey: DeVIT-TOX survey.

Unlabelled: Vitamin D intake over the recommended dose is usually associated with high serum 25(OH)D levels and generally not associated with symptoms of hypercalcemia. High doses of cholecalciferol need to be avoided to protect against vitamin D toxicity and related complications. Strict adherence to the clinical guidelines for treating vitamin D deficiency can ensure safe and effective treatment.

THE PREVALENCE OF CANCER AND ITS RELATION TO DISEASE ACTIVITY IN PATIENTS WITH ACROMEGALY: TWO CENTERS' EXPERIENCE.

Objective: Acromegaly is characterized by increased serum concentrations of growth hormone (GH) and insulin-like growth factor 1 (IGF-1). Although animal studies have demonstrated a relationship between these hormones and cancer risk, the results of human studies evaluating cancer prevalence in acromegaly are inconsistent. We aimed to investigate the prevalence of malignant neoplasms in patients with acromegaly.

Methods: This cross-sectional, single-center study was conducted in patients with type 2 DM who were followed in outpatient clinics of ophthalmology and internal medicine.

Effects of vitamin D supplementation on insulin resistance and dyslipidemia in overweight and obese premenopausal women.

Introduction: Vitamin D deficiency is a common problem, and it is related to increased risk of obesity, metabolic syndrome, atherosclerosis, and cardiovascular disease. Vitamin D has a beneficial effect on dyslipidemia and insulin secretion. We aimed to investigate the impact of vitamin D supplementation on anthropometric and laboratory parameters in overweight and obese premenopausal women.

Clinical and hormonal characteristics of patients with different types of hypophysitis: a single-center experience.

Objective: The inflammation of the pituitary gland is known as hypophysitis. It is a rare disease accounting for approximately 0.24%-0.

Stratifying the risk factors for hypoparathyroidism after total thyroidectomy. A single Center study.

Background: Post-operative hypoparathyroidism is a complication in patients who undergo thyroid surgery. Our study aimed to evaluate the incidence and causes of post-operative transient and permanent hypoparathyroidism in patients undergoing thyroid surgery.

Materials And Methods: The data of 933 consecutive patients who underwent total thyroidectomy in a single center were retrospectively evaluated.

The effects of three regimens of cholecalciferol (vitamin D) supplementation on vitamin D deficiency in non-obese and obese females.

Introduction: Vitamin D deficiency is a common health problem worldwide and tends to be a risk factor for all-cause mortality. We evaluated the effect of continuous low-dose oral daily and loading dose of oral weekly and loading monthly intramuscular (IM) vitamin D regimens on circulating levels of total 25(OH)D and in vitamin D deficient females, and between non-obese and obese subgroups.

Material And Methods: A total of 231 vitamin D deficient females were included to the study.

Serum Amyloid A, Paraoxonase-1 Activity, and Apolipoprotein Concentrations as Biomarkers of Subclinical Atherosclerosis Risk in Adrenal Incidentaloma Patients.

Background: Adrenal incidentalomas (AIs), particularly subclinical hypercortisolism (SH), are related to an increased risk of atherosclerosis. The anti-oxidative enzyme paraoxonase-1 (PON1) and the acute phase reactant serum amyloid A (SAA) are transported by highdensity lipoprotein and reciprocally regulated in acute inflammatory response. Our aim was to investigate serum SAA, PON1, and apolipoprotein levels as indicators of subclinical atherosclerosis in patients with nonfunctioning AI (NFAI) and SH.

Comparison of echocardiographic findings in patients with nonfunctioning adrenal incidentalomas.

Adrenal incidentalomas (AIs) are usually discovered incidentally after imaging unrelated to adrenal glands. We aimed to evaluate standard risk factors for systemic atherosclerosis and echocardiographic changes in patients with nonfunctioning AIs and compare them with normal subjects. We evaluated 70 patients diagnosed with AIs and 51 healthy controls.

The Relationship Between Increased Epicardial Fat Thickness and Left Ventricular Hypertrophy and Carotid Intima-Media Thickness in Patients With Nonfunctional Adrenal Incidentaloma.

Background: Emerging evidences indicate that patients diagnosed with Adrenal Incidentaloma (AI) may present cardiovascular complications. Epicardial fat thickness (EFT) has recently been described as a new risk factor and an active player in metabolic syndrome and cardiovascular disease.

Objectives: We aimed to evaluate the relationship between EFT and left ventricular hypertrophy and carotid intima-media thickness, which are both strong predictors of cardiovascular morbity and mortality, in patients with nonfunctioning AI.
