We describe a female neonate born from consanguineous parents who presented at birth with respiratory distress and severe hypoglycemia. At six months of age, the child was admitted to the Intensive care Unit because of two critical episodes characterized by fever and loss of consciousness. Child condition were critical and suggestive of sepsis, but blood tests showed severe hypoglycemia (19 mg/dl), hyponatremia (Na 132 mmol/l), compensated metabolic acidosis and increased infl...

Background: Congenital hypopituitarism (CH) is characterized by a deficiency of one or more pituitary hormones. Mutations in the genes coding for transcription factors, such HESX1, involved in the development of the pituitary, determine a highly variable phenotype which may include severe midline defects, septo-optic dysplasia and other congenital abnormalities. A small number of HESX1 variants have been identified in humans. The phenotype sh...

Introduction: Laron Syndrome (LS) or primary growth hormone (GH) insensitivity is an autosomal recessive disorder due to variants in the GH-receptor (GHR) gene or to post-receptor defects. LS prevalence is estimated 1-9/1000000. We report a case of LS with a missense variant in the GHR gene not previously described.Case: female, Turkish, was referred to our clinic for short stature. Born at term, birth ...

Background: GH secretion is classically assessed by provocative tests and, indirectly, by IGF-1 serum levels. However, their diagnostic accuracy is low. The aim of the study was to evaluate the adult height (AH) in short patients with IGF-1 ≤-1,5 SDS.Method: 52 short patients (height-SDS -2.6 (-3.1- -2.3), age 12.2 (10.2-13.7) y, 36 boys), with low height velocity(HV)-SDS (-1.6 (-3.2- -0.9)) and IGF-1 ≤-1,5 SDS (-2...

Introduction: McCune Albright Syndrome (MAS) is a rare disorder caused by somatic activating mutations of the GNAS gene, characterized by monostotic/polyostotic fibrous dysplasia, café au lait skin pigmentation and hyperfunctioning endocrinopathies. We report a case of MAS presenting with mild phenotypic characteristics and central precocious puberty (CPP).Case: Indian female was referred to our clinic fo...

Introduction: The association between ATD and AIG is very poorly characterized in pediatric age. We review the prevalence of the anti-gastric parietal cells antibodies (APCA) in young patients with ATD and we evaluated the development of AIG during follow-up, in order to define the usefulness of these markers for AIG screening in these patients.Patients and Methods: We evaluated 220 children and adolescents (11.28 ±...

Background and Aim: The relationship between T1DM and autoimmune thyreopathies is known and described, but the relationship between thyreopathies and other type of diabetes is not sufficiently clarified in pediatric age. The aim of our study was to assess the prevalence of autoimmune thyroid diseases (ATD) in children and adolescents with maturity onset diabetes of the young (MODY) in comparison with patients with T1DM and control group....

Background: Chronic granulomatous disease (CGD) is a rare primary immunodeficiency. Growth retardation is a common finding, due to recurrent severe infections and inflammatory complications. Bone marrow transplantation (BMT) can lead to stable remission, with overall pediatric survival rates > 90% after non-myeloablative conditioning transplants. As reported in previous studies, growth rates in CGD recovered following BMT.<strong...

Background: Kallmann syndrome (KS) is a genetic disorder, mainly characterized by the association of anosmia (due to hypo/aplasia of the olfactory bulbs) and hypogonadotropic hypogonadism (due to GnRH deficiency). Both partial or complete forms are described. Other features (skeletal and renal malformations, deafness, bimanual synkinesis) can be variably associated. Behind this phenotypic heterogeneity, there is a considerable complexity of genetic mutations. KAL1, <e...

Background: The Wilms tumor suppressor gene 1 (WT1) is essential for kidney and gonadal development. WT1 gene mutations are associated with two syndromes called Denys-Drash (DDS) and Frasier (FS) that clinically overlap and differ in the type of mutation and in the age at nephropathy onset. In 46,XY subjects WT1 mutations are associated with steroid-resistant nephrotic syndrome (NS), Wilms tumor, disorder of sex development (DSD) with dysgenetic gonads and gonadoblastoma risk....
