Long-term results of US-guided high-intensity focused ultrasound treatment of benign thyroid nodules

Kovatcheva Roussanka , Vlahov Jordan , Stoinov Julian , Zaletel Katja

Introduction: Thyroid nodules can be detected by ultrasound (US) in 20–30% of unselected populations. Various non-surgical techniques such as laser and radiofrequency ablation have been developed to reduce thyroid nodule size. High-intensity focused ultrasound (HIFU) ablation is a new, non-invasive method that has been shown recently. The aim of our study was to assess the long-term efficacy and safety of US-guided HIFU treatment of benign solid thyroid nodules.<p cla...

Correlation between parathyroid adenoma volume and markers of calcium-phosphate metabolism in patients with primary hyperparathyroidism

Yankova Inna , Ivanova Gergana , Shinkov Alexander , Kovatcheva Roussanka

IntroductionIn primary hyperparathyroidism (PHPT) the chronic overproduction of parathormone (PTH) is mostly due to a solitary adenoma.AimThe aim of our study was to examine the relationship between calcium-phosphate metabolism and the volume of the parathyroid adenoma (PTA) in patients with PHPT.Material and methodsThe study included 195 patients with biochemical...

Thyroid-receptor antibodies, immunoglubulin E and antinuclear antibodies in patients with Graves’ disease and their association with Graves’ orbitopathy and smoking habits

Stoynova Mariya , Shinkov Alexander , Kirilov Georgi , Kovatcheva Roussanka

IntroductionThyrotropin-receptor antibodies (TRAb) play a key role in the pathogenesis of Graves’ disease (GD) and Graves’ orbitopathy (GO) and are important for the diagnosis of both diseases. Elevated levels of immunoglobulin E (IgE) and antinuclear antibodies (ANA) were also found in GD patients. Smoking is a risk factor for GD and GO development and GO progression. We aimed to assess the associations between TRAb, IgE and ANA, and the prese...

The nodular goiter is the most prevalent thyroid disorder. Its prevalence increases with age and reaches over 70%. The aim of the study was to compare the nodule prevalence in two population-based studies, carried in Bulgaria in 2006 and 2012.Material and methods: Two thousand four hundred and two subjects (1347 female and 1053 male, age range 20–94 years) were included in 2006 and 2022 (1073 female and 949 male, 20–88 years) in 2012. All subje...

Shinkov Alexander , Borissova Anna-Maria , Atanassova Iliana , Kovatcheva Roussanka , Vlahov Jordan , Aslanova Nina

The aim of the study was to investigate the relationship among the indices of insulin resistance (IR), the lipid parameters and thyroid function in euthyroid adults.Material and methods: Two hundred and sixteen euthyroid adults, mean age 57.08±13.81 years (112 female and 104 male) were included. Serum lipirds, Immunoreactive insulin, glucose, TSH, waist circumference (WC), body height and weight were measured. HOMAi and BMI were calculated.<p cl...

Increased gene expression of TIMP1 and CHI3L1 in fine-needle aspiration biopsy washouts from papillary thyroid cancer

Dimitrova Inna , Shinkov Alexander , Dodova Rumyana , Ivanova Radina , Kaneva Radka , Kovatcheva Roussanka

AimTo assess the relative expression of tissue inhibitor of metalloproteinase-1 gene (TIMP1) and chitinase-3-like protein 1 gene (CHI3L1) in fine-needle aspiration biopsy (FNAB) washouts and the serum levels of their protein products (TIMP-1 and chitinase-3-like protein 1 also known as YKL-40) in patients with histologically confirmed papillary thyroid cancer (PTC) and with benign nodules. Further, we evaluated the correlation between the gene expression...
