Introduction: Subclinical hypothyroidism (SH) is a biochemical condition characterized by serum levels of TSH above the reference range upper limit (4,5μUI/mL), with normal concentrations of thyroid hormones. In cases of non-autoimmune subclinical hypothyroidism (NASHT), genetic defects have been described and can determine disorders in the biosynthesis process of thyroid hormones, such as heterozygous mutations in the TSH receptor gene (TSHR) and ...

Preterm and low birth weight(LBW) newborns are at risk of thyroid dysfunction during a critical period for neurodevelpment and this dysfunction can be missed in congenital hypothyroidism screening program(CHSP). Consequently, reassessment of thyroid function has been promoted in neonatal units, added to CHSP.Objectives: To evaluate prevalence and risk factors of thyroid dysfunction in≤32weeksGA and/or 1500g newborn, and compare differ...

Background: Hyperinsulinemic hypoglycemia is a heterogeneous condition characterized by inappropriate insulin secretion in the presence of low blood glucose levels. It can have various causes, including genetic, metabolic, syndromic, autoimmune, insulinoma, non-insulinoma pancreatogenous hypoglycemia or non-islet cell tumor hypoglycemia. On the other hand, oculofaciocardiodental syndrome is a rare X-linked dominant condition characterized by multiple congenita...

Background: POR deficiency is a rare form of congenital adrenal hyperplasia, transmitted in an autosomal recessive trait, that is characterized by ambiguous genitalia, impaired steroidogenesis and skeletal malformations similar to those of Antley-Bixler syndrome. It is caused by mutations in the P450 oxidoreductase gene (POR), an electron donor for all microsomal P450 enzymes including the three steroidogenic enzymes P450c 17 (17 alfa-hidroxylase /17,20 lyase)...

Background: Simultaneous pancreas kidney transplantation (SPKT) is a standard treatment option for young adults with type I diabetes (T1D) and concurrent renal failure. Despite the long-term immunosuppressive therapy the patients have better glycemic control, normalized renal function and an improved quality of life. Whether this is also reflected in the skeleton is not that clear yet.Methods: Patients were prospectively...

Background: Disorders of Sex Development (DSD) are a rare disease often caused by complex genetic mechanisms, with a wide spectrum of clinical manifestations that lead to a continous evolution of the diagnostic classification. From 2002, In the Veneto Region, all DSD diagnoses have been collected thanks to the creation of a Registry for Rare diseases, including DSD.Material and Methods: We could retrospectively analyze t...

Background: Few previous studies suggested an association between insulin resistance (IR) and TSH serum levels in euthyroid patients. This relation could have some particularities in populations characterized by intrinsic insulin resistance like polycystic ovary syndrome (PCOS) patients.Objective and hypotheses: The aim of our study was to study the relationship between IR and TSH serum levels in adolescent euthyroid PCOS patients....

Background: Dent’s disease is an X-linked recessive proximal tubulopathy characterized by low molecular weight proteinuria, hypercalciuria, nephrocalcinosis, nephrolithiasis, and progressive renal failure. Growth retardation, due to resistance to GH action is a feature commonly associated with Dent’s disease.Case report: We describe a boy diagnosed with Dent disease, treated with recombinant human GH. He was initially referred at 6 years of age...

Case report: A 13-year old boy treated with rGH for short stature due to isolated GH deficiency was submitted in our clinic in June 2014 for regular follow-up. From his medical history we note that he was diagnosed with GH deficiency in 2009 (−4.5 S.D.) and started treatment with rGH 0.035 mg/kgc per day since February 2009. The physical exam showed H=149.9 cm (−0.74 S.D.), 39 kg, Tanner P3G3 and a subcutaneous left paravertebral tumou...

Background: Congenital hypothyroidism (CH) is a treatable thyroid hormone deficiency that causes intellectual disabilities and growth deficiency if not detected and treated early.Material and Methods: We retrospectively analyzed the medical records of 22 patients, 13 (59%) females and 9 (41%) males, with positive CH screening at birth and confirmed by TSH & FT4 serum concentrations measurements, thyroid ultrasound an...
