Sawicka Beata , Borysewicz-Sańczyk Hanna , Michalak Justyna , Bossowski Artur ,

Non-classic form of congenital adrenal hyperplasia due to 21-hydroxylase deficiency is the most common disorder, which is associated with the use of hydrocortisone. Clinically patients present the GnRH-independent precocious puberty with rapid growth and advanced bone age. Inappropriate inhibition of androgen secretion can induce precocious central puberty. We present the case of 9-year-old girl, who was treated of the congenital adrenal hyperplasia due to 21- hydroxylase defi...

Application of Shear Wave Elastography (SWE) in the ultrasound evaluation of thyroid nodules in children and adolescents

Borysewicz-Sańczyk Hanna , Bossowski Filip , Sawicka Beata , Michalak Justyna , Dzięcioł Janusz , Bossowski Artur

Introduction: Shear wave elastography (SWE) is an ultrasound diagnostic method used to measure tissue stiffness. Since the mechanical properties of tissue involved in the pathological process are changed, SWE might indicate regions of the examined tissue covered by the disease. It is well documented, that SWE helps differentiate benign and malignant nodules in thyroid gland in adults, however there are still few studies on application of SWE in thyroid diagnos...

Effects of methimazole therapy on effector T and B regulatory cells in pediatric patients with Graves' disease

Stożek Karolina , Grubczak Kamil , Starosz Aleksandra , Bossowski Filip , Moniuszko Marcin , Bossowski Artur

Introduction: The incidence of autoimmune thyroid diseases (ATD) is constantly rising. Graves’ disease (GD) remains the most common cause of thyrotoxicosis in pediatric population, but the exact pathogenesis of GD is still not fully understood. The immunological basis of ATD assumes an imbalance between effector and regulatory T lymphocytes. B regulatory cells (Breg) are able to suppress the pro-inflammatory properties of effector T cells. Methimazole (M...

Thyrotropin receptor stimulating antibodies in pediatric patients with Graves’ diseases using ultra-rapid turbo bioassay

Bossowski Artur , Hatun Burak , Sawicka Beata , Stożek Karolina , Bossowski Filip , J Kahaly George

Background: Thyrotropin receptor (TSH-R) stimulating autoantibodies (TSAb) are present in 90-100% of patients with Graves’ disease (GD). TSAb are functional, impact thyroid function, and are clinically relevant. This study we performed in a pediatric patients with dynamic of Graves’ disease before and during methimazole therapy and in patient with Hashimoto’s thyroiditis using a novel and ultra-rapid TSAb andTBAb bioassay.<p class="abstex...

Change in timbre of voice as one of the signs of hyperandrogenism in a 11-year-old girl- a case report

Sawicka Beata , Szarras-Czapnik Maria , Borysewicz-Sanczyk Hanna , Michalak Justyna , Stozek Karolina , Bossowski Artur

Background: Partial gonadal dysgenesis with a 46,XY karyotype (46,XY PGD) is a disorder of sex development (DSD) associated with abnormal development of the gonads. It is characterized by abnormally developed external genitalia with or without Mullerian structures. The degree of abnormality varies from a female phenotype with clitoral hyperplasia to a male phenotype with isolated hypospadias. The incidence is unknown. In 20-30% of patients, gonadoblastoma or i...

Assessment of serum concetrations of decorin, vaspin and kallistatin in children with type 1 diabetes

Polkowska Agnieszka , Bossowski Filip , Żelazowska-Rutkowska Beata , Marcinkiewicz Katarzyna , Nesterowicz Miłosz , Leoniuk Rafał , Bossowski Artur

The increasing knowledge on the functions of gastric peptides and adipokines in the body allows the assumption of their major role linking the process of food intake, nutritional status, and body growth, largely through the regulation of glucose metabolism and insulin resistance. The aim of the study was the assessment of serum levels of selected gastric peptides and adipocytokines in children with type 1 diabetes, with respect to the disease duration. The study included 88 ch...

Retrospective assessment of malignant thyroid nodules in a group of polish children and adolescents involving elastography

Borysewicz-Sańczyk Hanna , Sawicka Beata , Karny Agata , Bossowski Filip , Marcinkiewicz Katarzyna , Rusak Aleksandra , Dzięcioł Janusz , Bossowski Artur

Introduction: Thyroid nodules occur in 1.8% children which is not so often in comparison to adults (19–68%), but in children they appear to be at higher risk of malignancy (22–26% vs.5–10% respectively). It has been shown that the probability of thyroid nodules malignancy correlates with the presence of characteristic ultrasonographic features. Elastography - the noninvasive ultrasound imaging technique based on estimation of the tissue flexi...

Bossowski Artur , Rydzewska Marta , Michalak Justyna , Bossowska Anna , Chen Shu , Black Sarah , Powell Michael , Furmaniak Jadwiga , Smith Bernard Rees

Background: Zinc transporter 8 autoantibodies (ZnT8Abs) together with glutamic acid decarboxylase autoantibodies (GADAbs), insulinoma antigen 2 autoantibodies (IA-2Abs) and insulin autoantibodies (IAbs) are markers of type 1 diabetes mellitus (T1DM). We studied the prevalence of ZnT8Ab in children with autoimmune thyroid diseases (AITDs) to assess the association of AITDs and T1DM at the serological level.Methods: The st...
