Introduction: Disorders of sex development (DSD) describes conditions affecting gonadal and adrenal function and therefore to large extent affect fertility. In some cases the gonads have been removed due to risk of malignancy. Information to the patients about their fertility and treatment options have not been optimal in the past.Objective: To describe fertility outcome in the different diagnostic groups of DSD and to assess to what extent assisted repr...

Background: There is increasing evidence from epidemiological studies that some man-made chemicals present in the environment can disrupt endocrine homeostasis in exposed humans. Exposure during foetal life to e.g. phthalates has been linked to adverse effects on testicular and ovarian development, thyroid homeostasis and growth in postnatal life. Exposure to phthalates fluctuates not only from day to day but also over time which poses a major challenge for ex...

In Italy, treatment of children with CP is not centralized. We collected data of 117 patients (pts) (M/F 56/41) with CP diagnosed after 01/01/2000, followed-up in 14 centres of paediatric endocrinology belonging to the I.S.P.E.D. Five centres provided data on more than 10 pts (range 12-19), while the remaining on 1-9. 46 pts were diagnosed between 2000-2010 and 71 afterwards. Follow-up was 7.5±4.1 yrs.Results. Histology was adamanti...

Background: Cleidocranial dysplasia (CCD) is a very rare dominantly inherited autosomal bone disorder mainly characterized by hypoplasia or aplasia of clavicles, failure of cranial suture closure, dental anomalies, short stature, and other changes in skeletal patterning and growth. Heterozygous loss-of-function mutations cause the majority of the abnormalities in the run-related transcription factor 2 gene (RUNX2). This gene is located on chromosome 6p21 and i...

Introduction: in females with precocious thelarche (PT) (< 8 years), elevation of morning luteinizing hormone levels (mLH) may be indicative of pubertal activation of the pituitary gonadal axis. However, this approach could not be satisfactory in real life management of PT due to the risk of reduced specificity and sensitivity of the mLH thresholds. We propose a diagnostic flow-chart based on basal and stimulated gonadotrophins integrated with bone age and ...

Introduction: The gonadotropin releasing hormone stimulation test (GnRHST) is commonly used to screen CPP. Some recent studies reported that morning unstimulated luteinizing hormone levels may be sufficient to discriminate pubertal from prepubertal children. The aim of this study is to evaluate the clinical efficacy of mLH to screen CPP in femalesPatients and Methods: We retrospectively studied the clinical and hormonal ...

Background: Idiopathic hypogonadotropic hypogonadism (IHH) is due to the failure of gonadotrofin releasing hormone (GnRH) secretion which impairs the physiological initiation of puberty. About 30 to 50% of IHH is associated to hereditary causes and about 50 mutated genes have been identified.Objective and methods: We present three intra-familial cases of normosmic IHH (nIHH) related to a new association of two hetero...

The WT1 gene has a crucial role in the genesis of the bipotential genital ridge and subsequently in the specification of the Sertoli cells of testis. Mutations involving the WT1 gene are associated with a wide range of phenotypes impacting testis-determination and development including Denys-Drash syndrome, Frasier syndrome and Meacham syndrome. Here, we describe two sibs with DSD carrying a de novo mutation in the WT1 gene. A girl was born with Prader IV intersex genitals. Cy...

Background: Functional insulin therapy allows precise insulin adjustments to achieve normoglycaemia.Objective and hypotheses: To assess metabolic control (A1c) and lipid profile in children and adolescents with DM1 in a 3-year period under multiple daily injections (MDI) since the diagnosis.Method: Retrospective analysis of children and adolescents under functional insulin therapy since the diagnosis of DM1. The variables studied w...

Background: Central precocious puberty is due to premature activation of the hypothalamo–pituitary–ovarian axis. In girls it is idiopathic in up to 95%. Children with clinical rapid progression are treated with prolonged activity GnRH agonist.Objective and hypotheses: Characterise cases of idiopathic central precocious puberty (ICPP) followed at our hospital comparing the group treated with GnRH agonist (group A) with the group not treated (gro...
