Introduction: Acromegaly is usually caused by pituitary macroadenoma producing excess growth hormone. Treatment options include surgery to remove the tumor, medications, and radiation therapy.Case report: A 39-year-old woman has been referred to the endocrine clinic with suspected acromegaly in December 2019. Surgery for benign ovarian cyst, endometriosis, amenorrhoea, unsuccessful in vitro fertilisations were present in her medical history. She complain...

Objectives: The use of levothyroxine (LT4) treatment aiming to improve fertility in euthyroid women with positive thyroid peroxidase antibodies (TPOAb), is not supported by the available evidence, however the extent to which this is applied in clinical practice is unknown. The aim of the study was to document the demographic, work-related characteristics, and therapeutic choices of European physicians in the case of euthyroid infertile women positive for TPOAb.<p class="ab...

Drinking water is the major natural source of iodine in many European countries. In the present study, we examined possible sites of iodine loss during the usual water purification process. Water samples from 6 sites during the technological process were taken and analyzed for iodine content. Under laboratory circumstances, prepared iodine in water solution has been used as a model to test the effect of the presence of chlorine. Samples from the purification sites revealed tha...

Objectives: Differentiation of orbital fibroblasts (OFs) into myofibroblastic phenotype contributes to tissue remodelling in thyroid eye disease (TED). Our study aimed to investigate the impact of TGF-β1 induced myofibroblast differentiation on hyaluronan turnover, with a particular focus on the expression of its key enzymes.Methods: OF cultures were established from tissue samples acquired from decompression surgeries of patients with TED (TED-OFs;...

Introduction: During the course of thyroid eye disease (TED) immune cells infiltrate the orbital connective tissue leading to overstimulation of orbital fibroblasts (OFs). In the persistent inflammatory environment, OFs differentiate into myofibroblasts or adipocytes, simultaneously creating two phenotypes with different morphology and function. Activated OFs secrete pro-inflammatory cytokines and growth factors and contribute to the prolonged inflammation, among other things ...

Background: Hypothyroidism is one of the most frequent conditions in endocrinology. Despite of that fact, indications for treatment differ among specialists in Spain.Aims: To identify attitudes of Spanish endocrinologists in the use of levothyroxine (LT4) therapy and the management of hypothyroidism.Methods: The members of the Sociedad Española de Endocrinología y Nutrición (Spanish Society of Endocrinology ...

Introduction: In acromegaly GH excess leads to impaired insulin sensitivity with an alteration of beta-cell function. The consequent hyperglycemia leads to a further increased cardiovascular risk and mortality.Case report: A 16 years old patient was first referred to the Department of Pediatrics in 2014 with accentuated growth since the age of 10. The reason of the first referral was a sport injury (head trauma during playing basketball). Sella MRI depic...

Background: The standard, lifelong therapy of phenylketonuria (PKU) is natural protein-restricted diet completed with Phenylalanine (Phe)-free L-amino acid mixtures that provide the daily necessary micronutrients, such as iodine and selenium. Our main objective in this study was to assess the iodine and selenium status of patients with PKU, based on their adherence to the low-Phe diet, compared to a healthy control group. Secondly, we aimed to asses whether adherence to therap...

Introduction: Insulinoma is a rare tumor of the beta cells of the pancreas. The clinical manifestation is diverse with hypoglycemia and autonomic neurological symptoms. For diagnosis the Whipple’s triad needs to be present: signs of hypoglycemia, glucose level under 3 mmol/l and the cessation of symptoms after administration of iv. glucose. The fasting test confirms the diagnosis. The most commonly used imaging techniques that may localize the tumor are the abdominal ult...

Papillary thyroid cancer (PTC) cells and immune cells can kill each other by death ligands. Death ligands induce apoptosis only in sensitive cells. The sensitivity to apoptosis is regulated in a complex and poorly understood manner. The aim of this study was to investigate the Fas ligand (FasL) and Tumor Necrosis Factor-Related Apoptosis Inducing Ligand (TRAIL) expression in PTC cells and tumor infiltrating immune cells. Twenty-six PTCs without and fifteen PTCs with cervical l...
