Fractionated dosage of radioiodine for the ablation of low-risk differentiated thyroid cancer has no impact on survival.

Introduction: Due to a limited number of hospital beds dedicated to radioiodine therapy (RIT) in some countries, a fractionated dose of radioiodine may be considered as the ablation therapy of differentiated thyroid cancer (DTC). The aim of the study was to compare the late effects of ablation therapy with single and fractionated dose of radioiodine in patients with DTC.

Patients And Methods: Patients with low-risk DTC referred to our institution 5-16 weeks after thyroidectomy, treated with 2.

Shear wave elastography in the diagnostics of parathyroid adenomas-new application of the method.

Purpose: Shear wave elastography (SWE) was described as valuable tool in the diagnostics of distinct types of thyroid lesions, thyroiditis and several other non-thyroidal conditions, such as liver inflammation and fibrosis or diagnostics of breast lesions. The aim of the current study was to assess the appearance of parathyroid adenomas in SWE and to check prospectively if SWE can be valuable additional tool in the diagnostics of pathologically enlarged parathyroids.

Methods: Patients with parathyroid adenomas confirmed by histopathology were included.

Content of RNA originating from thyroid in washouts from fine-needle and core-needle aspiration biopsy - preliminary study.

Introduction: In the evaluation of molecular markers in washouts from fine-needle aspiration biopsy (FNAB) the extremely small amount of material can be a major problem. Some authors tried to use washouts from core-needle aspiration biopsy (CNABs) to gain more material from larger needles. However, according to some studies, CNAB samples are commonly contaminated with blood.

Risk of malignant neoplasms in acromegaly: a case-control study.

Purpose: Acromegaly is a chronic disease resulting from pathological oversecretion of growth hormone and subsequently insulin growth factor-1. Several complications of the disease have been reported, including cardiovascular diseases, respiratory disorders but also increased risk of benign and malignant neoplasms. The aim of the study was to evaluate the risk of malignant neoplasms in the patients with acromegaly in comparison with the control group.

The usefulness of fluorine-18 fluorodeoxyglucose PET in the detection of recurrence in patients with differentiated thyroid cancer with elevated thyroglobulin and negative radioiodine whole-body scan.

Introduction: PET/computed tomography (CT) using fluorine-18 fluorodeoxyglucose (F-FDG) has been used in the diagnosis of recurrence and metastases of differentiated thyroid cancer (DTC) in cases of negative whole-body scan (WBS) despite elevated concentrations of stimulated thyroglobulin (Tg).

Aim: To assess the utility of PET/CT in the detection of recurrence among patients with DTC with increased Tg levels and negative results of WBS.

Materials And Methods: PET/CT results were retrospectively analyzed in patients with DTC with increased Tg and negative results of WBS as well as negative cervical ultrasonography and chest radiography.

Dysfunction of the thyroid gland during amiodarone therapy: a study of 297 cases.

Aim: This study aims to explore and compare the efficacy of radioiodine treatment (RIT) in hyperthyroid and euthyroid patients who have been treated with amiodarone (AM) in the past or are currently undergoing AM treatment. Clinical observation of a group of patients with amiodarone-induced hypothyroidism during a 12-month follow-up period was used for comparison.

Design: This was a observational, two-centered study.

Comparison of diagnostic yield of core-needle and fine-needle aspiration biopsies of thyroid lesions: Systematic review and meta-analysis.

Objectives: Thyroid nodular disease is one of the most commonly observed medical conditions. Cytological evaluation of the specimens obtained with fine-needle aspiration biopsy (FNAB) is the most accurate tool for selecting nodules which should be further surgically removed. A major limitation of this method is the high occurrence of non-diagnostic results.

VEGF-C Is a Thyroid Marker of Malignancy Superior to VEGF-A in the Differential Diagnostics of Thyroid Lesions.

Introduction: Thyroid nodular goiter is one of the most common medical conditions affecting even over a half of adult population. The risk of malignancy is rather small but noticeable-estimated by numerous studies to be about 3-10%. The definite differentiation between benign and malignant ones is a vital issue in endocrine practice.

Treatment of severe thyroid function disorders and changes in body composition.

Introduction: Hyper- and hypothyroidism are accompanied by altered metabolic rate, thermogenesis, and body weight. The aim of this study was to estimate the relation between treatment-induced changes in thyroid function, and the accompanying body composition in patients with either severe hypo- or hyperthyroidism.

Material And Methods: Body composition analysis and hormonal assessment were measured at the initial diagnosis of thyroid disorder, after three-month treatment, and finally after complete recovery from hyperthyroidism (n = 18) or hypothyroidism (n = 27).

Emotional functions in transsexuals after the first step in physical transformation.

Transsexuals have to face multiple medical, social and bureaucratic problems. These problems are not only encountered before the transformation, but also during and after medical procedures. In the search for improvement of transsexual individuals' quality of life during therapy, it seems desirable to supplement hormonal treatments with psychological explorations.

Dependence of thyroid sonographic markers of malignancy and its influence on the diagnostic value of sonographic findings.

Introduction: Thyroid nodules constitute frequent medical condition. Ultrasonographic (US) examination remains the basis in the diagnostics of nodular goiter and selection of the suspected ones requiring fine-needle aspiration biopsy (FNAB). The aim of this study was to evaluate if the features so far considered to be US malignancy markers are dependent or independent variables and to check if these data are clinically relevant.

Radioiodine therapy in patients with type II amiodarone-induced thyrotoxicosis.

Introduction: The treatment of amiodarone-induced thyrotoxicosis (AIT) still remains a clinical challenge, requiring the cooperation of both endocrinologists and cardiologists. Unfortunately, even today AIT is related to significantly increased mortality.

Objectives: The aim of this study was to compare the efficacy of radioidine therapy for type II AIT in 2 groups of patients: with high or normal radioiodine uptake and treated by amiodarone (AM) in the past (AM- group) and with low radioiodine uptake and currently treated with AM (AM+ group).

The usefulness of standardized uptake value in differentiation between benign and malignant thyroid lesions detected incidentally in 18F-FDG PET/CT examination.

Introduction: In the last decade, (18)F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET and PET/CT) has become one of the major diagnostic tools used in oncology. A significant number of patients who undergo this procedure, due to non-thyroidal reasons, present incidental uptake of (18F-FDG) in the thyroid. The aim of the study was to compare the SUVmax (standardized uptake value) of thyroid focal lesions, which were incidentally found on PET/CT, in relation to the results of thyroid fine-needle aspiration biopsy (FNAB) and/or histopathological evaluation.

Shear wave elastography: a new noninvasive tool to assess the intensity of fibrosis of irradiated salivary glands in head and neck cancer patients.

The aim of the study was to assess salivary gland parenchyma by means of sonoelastography in patients irradiated for head and neck squamous cell carcinoma (HNSCC). The studied group consisted of 52 patients after radiotherapy (RT) and 54 healthy volunteers. All of the former were treated for advanced larynx (40), oropharynx (9), or maxilla (3) squamous cancers and suffered from chronic dryness.

How to select nodules for fine-needle aspiration biopsy in multinodular goitre. Role of conventional ultrasonography and shear wave elastography - a preliminary study.

Introduction: The wide prevalence and relatively low malignancy ratio of thyroid nodular disease (TND) make the selection of suspicious lesions for fine-needle aspiration biopsy (FNAB) a vital problem in endocrinology. Apart from the decision as to whether FNAB is necessary, there is often a second problem - which nodule or nodules to choose in a case of multinodular goitre (MNG), when the number of lesions may be high. The aim of this study was to compare the usefulness of conventional ultrasonography (US) to that of a novel method of tissue stiffness assessment - shear wave elastography (SWE) - in differentiating between malignant and benign nodules and in selecting the most suspicious lesions in MNG.

Biochemical and ultrasonographic parameters influencing thyroid nodules elasticity.

Elastography is a method of tissue stiffness assessment. It has already been demonstrated that thyroid cancers are less elastic than benign lesions. However, little is known about other factors, which might influence the stiffness of thyroid nodules and disrupt the prediction of malignancy using this technique.

Core needle biopsy of thyroid nodules - evaluation of diagnostic utility and pain experience.

Objective: A crucial problem in the non-operative diagnosis of thyroid nodules is the significant amount of non-diagnostic biopsies. This is a challenge for practicing endocrinologists especially when the results of the repeated biopsies remain non-diagnostic. The lack of a concrete preoperative diagnosis may result in unnecessary thyroidectomies in patients.

Differences in the psychological and hormonal presentation of lean and obese patients with polycystic ovary syndrome.

Background: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders found in women of reproductive age. Differences in hormonal and metabolic profiles are observed in groups of patients with normal and elevated BMI. Cause of disturbances observed in the two groups of patients with PCOS is analyzed.

Comparison of diagnostic value of conventional ultrasonography and shear wave elastography in the prediction of thyroid lesions malignancy.

Introduction: Thyroid nodular disease (TND) is a very common disorder. However, since the rate of malignancy is reported to be 3-10%, only a minority of patients require aggressive surgical treatment. As a result, there is a need for diagnostic tools which would allow for a reliable differentiation between benign and malignant nodules.

Individual plasma ghrelin changes in the same patients in hyperthyroid, hypothyroid and euthyroid state.

Ghrelin is a multifunctional peptide of widespread expression. Since it has been shown to influence energy homeostatis, its potential role in thyroid dysfunction may have clinical significance. In this study, plasma ghrelin changes have been analyzed in the same patients in three different thyroid states for the first time.

Patients with chronic hepatitis type C and interferon-alpha-induced hyperthyroidism in two-years clinical follow-up.

Objectives: Interferon-α (IFN-α) is a gold standard in the therapy of viral chronic hepatitis type C (CHC). However, such treatment might lead to thyroid dysfunction. Patients usually present hypothyroidism, but rarely also hyperthyroidism may develop.

Smoking and endocrine disorders.

Patients suffering from endocrine disorders, which affect the function of central nervous system, need a special care and approach in the process of smoking cessation. The process of informing about negative effects of smoking addiction, including potential aggravation of the disease, has to be specially tailored to the need of the patient and the type of the disease. The informing physician should also serve as a model by not smoking and try to confirm the patient about positive benefits of quitting smoking.

[The problem of cigarette smoking in the workplace].

European countries take various actions to reduce smoking, including an introduction of appropriate legislation. In Poland, the main piece of legislation is the Act of 9 November 1995 on protection of health against the consequences of tobacco use and their products. Among the places where smoking is prohibited, the document mentions all indoor areas of workplaces, among others.
