Introduction We aimed to investigate malignancy rates in atypia of undetermined significance (AUS) subcategories and their association with cytomorphologic and ultrasonographic features. Methods A total of 201 thyroid nodules with AUS cytology that underwent surgical resection were analy-zed, including 169 AUS-Nuclear (AUS-N) and 32 AUS-Other (AUS-O) nodules. Cytomorphological and ultrasonographic features, along with the American College of Radiology Thyroid Imaging Reporting and Data System (ACR-TIRADS) and the European Thyroid Imaging Reporting and Data System (EU-TIRADS) classifications, were analyzed to assess the association between malignancy and AUS subcategories.

Objective: This study aimed to evaluate the diagnostic performance of biochemical markers in normocalcemic primary hyperparathyroidism (nPHPT), analyse their temporal variations, and assess their correlation with adenoma localisation and size.

Methods: In this multicenter retrospective study-the largest patient cohort reported in the literature to date (n = 474) we comprehensively profiled normocalcemic patients diagnosed with primary hyperparathyroidism nPHPT was diagnosed based on persistently elevated PTH levels with normal serum calcium after excluding secondary causes such as vitamin D deficiency, renal impairment, and other conditions. This retrospective multicenter study included a large cohort of patients whose biochemical markers-including serum calcium, phosphorus, magnesium, vitamin D, parathyroid hormone (PTH), and glomerular filtration rate (GFR)-were measured at three time points, using standardised laboratory protocols.

Purpose: The primary objective of this study was to retrospectively evaluate the demographic, biochemical, and clinical characteristics of patients with asymptomatic primary hyperparathyroidism (aPHPT), analyze their long-term outcomes, and discuss the effectiveness of current therapeutic strategies in light of the existing literature. We anticipate that our study will provide clinicians with guidance regarding surgical decision-making beyond the standard criteria for aPHPT.

Methods: This was a nationwide, multicenter, observational, retrospective cohort study.

Medullary thyroid carcinoma is a rare neuroendocrine malignancy, with sporadic and hereditary forms accounting for 75% and 25% of cases, respectively. This study compares the clinicopathological features of sporadic medullary thyroid carcinoma (sMTC) and hereditary medullary thyroid carcinoma (hMTC) using real-world data to provide risk factors that aid in the early detection of the disease. The retrospective study comprised 77 patients with confirmed MTC treated at a tertiary referral center between January 2019 and December 2024.

Purpose: To assess the utility of blood cell-derived parameters in differentiating subacute thyroiditis (SAT) from Graves' disease (GD) and their association with recurrence and the development of permanent hypothyroidism in the patients with SAT.

Methods: The study involved 414 patients with SAT, 415 patients with GD, and 92 healthy controls. Pre-treatment hematological parameters were retrospectively compared, especially in cases where differentiation is challenging, including painless SAT, acute phase reactants negative SAT, and TSI, TRAB (Thyroid Stimulating Immunoglobulin, TSH-receptor-antibodies) negative GD.

Objective: Accurate tumor localization is necessary for the application of minimally invasive surgery, which is preferred in the treatment of primary hyperparathyroidism. Parathormone-washout (PTH-WO) is parathyroid fine-needle aspiration followed by PTH measurement in the needle washout fluid. This study aimed to determine appropriate cutoff values for the PTH-WO method.

Hypoparathyroidism is a disorder that causes renal complications, bone disease, an increased risk of cardiovascular diseases, neuromuscular complications, and ocular findings. In this study, we aimed to determine how well the existing guidelines were followed in the follow-up of patients with hypoparathyroidism. In the endocrinology and metabolism outpatient clinic, routine controls were conducted on patients 18 years of age and older with a diagnosis of hypoparathyroidism between February 2019 and September 2021.

Purpose: Our study aimed to discern disparities in metabolic, hormonal profiles, and comorbidities among patients with pituitary Cushing (PC), adrenal Cushing (AC), and Mild autonomous cortisol secretion (MACS).

Methods: We conducted a retrospective analysis involving 76 patients diagnosed with PC ( = 26), AC ( = 21), and MACS ( = 29) at our clinic. We compared the groups' demographic data, clinical characteristics, biochemical profiles, hormonal analyses, and surgical interventions.

Although seasonal changes were suggested to be among the many factors that affect thyroid functions, this issue is still controversial. In this study, we aimed to investigate the possible relationship between seasonal changes and thyroid function. We retrospectively scanned all thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4) values checked in our hospital between 2019 and 2023.

Article Synopsis
  • The study investigated the link between diabetic nephropathy (DN) and two markers of insulin resistance: the triglyceride/glucose (TyG) index and the triglyceride/high-density lipoprotein cholesterol (Tg/HDL-C) ratio.
  • Data from 15,378 individuals were examined, revealing that 35.1% of patients had DN, with females showing a 10% higher risk compared to males.
  • The TyG index indicated a significant risk for DN when above 9.58, while the Tg/HDL ratio was significant in early analysis but lost significance in more complex analysis.

Euglycemic diabetic ketoacidosis (DKA) is a rare complication of diabetes mellitus (DM) characterized by metabolic acidosis, ketosis, and blood glucose levels < 250 mg/dL. The prevalence of euglycemic DKA is increasing with the popularity of ketogenic (low-carbohydrate) diets. We present herein the case of a patient with newly diagnosed type 1 DM who developed euglycemic DKA following a ketogenic diet.

Article Synopsis
  • Nonalcoholic fatty liver disease is a common chronic liver condition linked to higher risks for type 2 diabetes and its complications, and the FIB-4 scoring system can help predict liver fibrosis.
  • This study reviewed medical records of 312 type 2 diabetes patients to evaluate the relationship between FIB-4 scores and microvascular complications like nephropathy, neuropathy, and retinopathy.
  • Results showed that while FIB-4 scores did not differ significantly for neuropathy or retinopathy, higher FIB-4 scores were associated with a greater prevalence of nephropathy, suggesting that FIB-4 scores could be a useful tool in predicting this specific complication in diabetic patients.

Introduction: High-resolution ultrasonography devices have led to the increased detection of thyroid nodules and the need for fine-needle aspiration biopsy (FNAB). However, FNAB is an invasive procedure that can cause discomfort and pain. Music therapy has been used for centuries to alleviate pain, and our clinical trial was conducted to investigate its impact on pain scores during thyroid FNAB.
