Objective: Multiple endocrine neoplasia type 1 (MEN1) is a rare heritable tumor syndrome caused by germline mutations of MEN1 gene affecting mainly the parathyroid, pituitary and pancreas. Phenotype varies widely, even in first-degree relatives. Recently it has been shown that functionally active gastroenteropancreatic neuroendocrine tumors (GEP-NETs), initially frequently diagnosed as sporadic cases, lead to MEN1 diagnosis. Non-functioning tumors are increasingly rec...

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...

Gastroscopic examination revealed numerous small polypoid lesions within the stomach, and histology of tissue samples obtained by biopsy showed carcinoid associated with atrophic gastritis. Although the patient had no symptoms of carcinoid sy...
