Background: Sertoli-Leydig Cell Tumors (SLCT) account only for 1% of all ovarian neoplasia, occur more commonly in the second or third decade of life and seldom secrete tumor markers. The experience in adolescence is limited.Objective and hypothesis: To report the hormonal and biological profile of a SCLT in a young adolescent. Ovarian tumor markers as well as FDG-PET scanning might be helpful in diagnosing ovarian malignancy in case of normal ultrasound...

Background: The main reason of decrement of growth in children with Prader-Willi Syndrome (PWS) is dysfunction of hypothalamo-hypophseal axis (HHA) and a decrease in the capacity of secretion of growth hormone (GH). In fact, in some cases, GH levels are normal, so there may be other factors in the etiology.Objective and hypotheses: In this study, 19 months old PWS case with growth failure is represented.Method: 13 months old male p...

Background: The aim of this study was to examine plasma visfatin levels in pediatric patients with type 1 diabetes (T1D). Visfatin, a novel adipokine, is predominantly secreted by visceral adipose tissue and seems to have insulin-mimetic effects. It has not been studied in children and adolescents with type 1 diabetes (T1D) yet.Objectives: We studied 124 subjects; 62 patients with T1D: 31 girls, mean age 13.7±3.7 years; mean duration of diabetes 5.9...

Background: Septo-optic dysplasia (SOD) is a rare disorder characterized by optic nerve hypoplasia, anterior midline abnormality and pituitary hormone deficiency. Mutations of several genes are known to cause SOD related condition, such as HESX1, SOX2, SOX3, and OTX2, but mutations of WDR11 has not been reported in SOD.Objective: Reporting the first SOD patient identified a mutation in WDR11.<p cl...

Background: Adrenal insufficiency is an important and potentially life-threatening condition, and it is also known as a rare cause of hypercalcaemia.Objective and hypotheses: Resistant hypercalcemia may be associated with hypocortisolism.Method: A 18-day-old male infant was born at 36 weeks by emergency cesarean section for fetal distress and intrauterine growth retardation. He was referred to paediatric endocrinology because of th...

Background: Vitamin D is an essential hormone in the homeostasis of calcium. Its main source is sun exposure. Changes in lifestyle and migratory movements have favored the reappearance of vitamin deficiency in our country.Method: We present three cases of newborn with hypocalcemic seizures, secondary to maternal vitamin D deficiency. Mother’s origin was North Africa.Results: Case 1: 7 days old male brought for several episodes...

Background: C-peptide secretion is the most accurate measurement of residual β-cell function in type 1 diabetes (T1D) and even residual levels seem to positively correlate with a lower probability of complications.Objective and hypotheses: Identify key determinants to the evolution of the β pancreatic cell function, measured by fasting C-peptide (FCP).Method: Prospective study of patients diagnosed with T1D, with evaluati...

Background: Patients with Klinefelter syndrome (SK) have a 47, XXY karyotype and tall stature as a result of overexpression of the SHOX gene. The case of a patient with peculiar phenotype, microcephaly, proportional short stature and 47, XXY karyotype with a deletion in band p11.3 of one X chromosome is presented.Clinical description: A 2-year, 4 month-old boy was referred for study of growth retardation. The product of a first gestation of 39 weeks of h...

Background: Pituitary gigantism is a rare disorder. Paediatric endocrinologists may see at most one or two patients during their careers. In one large series of 2367 children and adolescents with pituitary adenomas, only 15 (0.6%) had pituitary gigantism. Much of our understanding is derived from isolated case reports and extrapolation from the adult literature. No sex predilection is known. Gigantism may occur at any age, and has been observed as early as the first 6–9 m...

Background: Some studies suggested a correlation between vitamin D (VD) and the GH-IGF1 but few studies, and with controversial results, have prospectively analysed the vitamin D status in children before and after GH treatment.Objective and hypothesis: To assess VD status in pre-pubertal children with idiopathic GH deficiency (GHD); and to evaluate effect of GHD and GH treatment on VD levels.Methods: 50 pre-pubertal children with ...
