Disorders of sex development (DSD) are those congenital conditions in which development of chromosomal, gonadal, or anatomical sex is atypical. The aim of this study was to characterize the histology of 46,XX DSD prepubertal gonads. We studied 25 gonads of fourteen 46,XX DSD patients. The age of biopsy/gonadectomy was 1.17 (0.08–4.17) years (median and range). Molecular studies confirmed the absence of SRY by PCR and/or MLPA in blood samples of all patients and i...

Background: In Androgen insensitivity syndrome (AIS) is a hereditary disease in which AR mutations in 46,XY patients present with partial (PAIS) or complete (CAIS) defects in virilisation.Objective and hypotheses: The aim was to analyze the effect of lack of androgen action in germ cell (GC) health and survival along postnatal development, previous to Sertoli cell (SC) pubertal maturation.Method: The histological features and quant...

Background: Carriers of germline DICER1 mutations are predisposed to a rare cancer syndrome, the DICER1 syndrome, associated with tumors such as pleuropulmonary blastoma (PPB), ovarian Sertoli-Leydig cell tumors (SLCT), multinodular goiter (MNG), cystic nephroma (CN), embryonal rhabdomyosarcoma (ERMS) or primitive neuroectodermic tumor. DICER1 is involved in the generation of microRNAs (miRNAs), short, double-stranded, non-coding RNAs that modulate gene expression at ...

Objectives: Osteogenesis imperfecta (OI) is an extremely heterogeneous connective tissue disorder characterized by low bone mass, which together with altered bone matrix properties leads to skeletal fragility. Due to the wide range of symptoms, the pathophysiology of the OI is not fully understood. Null mutations in SERPINF1, encoding the potent antiangiogenic factor PEDF, cause type VI OI with excessive osteoid formation, abnormal osteoblast-osteocyt...

Introduction: Primary hypothyroidism is the most frequent thyroid disease in children, and elevation of serum TSH is a common presenting complaint (pc) in the pediatric endocrinology outpatient clinic. Subclinical hypothyroidism (sHT) predominates in relation to overt hypothyroidism (cHT). The benefit of Levothyroxine is controversial specially when serum TSH levels are less than 10 uUI/ml.Objectives: To evaluate the pre...

Background: IGF1R gene mutations have been associated with varying degrees of intrauterine and postnatal growth retardation, and microcephaly. We have previously reported three novel variants in the IGF1R gene: de novo p.Arg1256Ser, de novo p.Asn359Tyr and p.Tyr865Cys (ENDO 2013, OR20-2).Aim: To characterize the functional effects of the novel IGF1R gene allelic variants.Methods: In ...

Background: 25-Hydroxyvitamin D (25(OH)D) deficiency is reported to be common in patients with rheumatoid arthritis and associated with disease activity, physical disability, and cardiometabolic intermediates; data in patients with juvenile idiopathic arthritis (JIA) are inconsistent.Objective and hypotheses: To assess serum 25(OH)D in children, adolescents, and young adults with JIA, and to identify the risk factors for vitamin D deficiency in JIA patie...

Management of patients presenting a chronic endocrine or metabolic disease during transition period is a challenge for multiple reasons. The department of Adult Endocrinology and Reproductive Medicine in Pitie Salpêtrière Hospital, Paris has been involved in the management of such patients for many years. However, in our own experience, 81% of patients are still followed-up after 1 year, 71% after 3 years and only 49% after 5 years. Based on such experience, we decid...

Objective: To describe clinical, laboratory and genetic characteristics of 42 short children from 34 consanguineous Turkish families.Design: Descriptive case series.Methods: After collecting clinical information, DNA samples were analysed in three European laboratories. In 18 children (12 families) suspected of a genetic defect in the growth hormone (GH)-insulin-like growth factor ...

We present the case of a 11-years-old girl who came to our attention for a first critical episode lasting a few minutes, with spontaneous resolution, described as a generalized clonic tonic crisis, which occurred in full well-being. An electroencephalogram (EEG) was performed which showed focal epileptiform anomalies in the right temporal center that spread evoked by hyperpnea and eye closure and an EEG after sleep deprivation that showed an accentuation of the anomalies in ph...
