Background/Aims: 46,XY gonadal dysgenesis (GD) is classified as complete (CGD) or partial (PGD) depending on gonadal morphology and function. In contrast to the typical female external genitalia in CGD, the phenotype of PGD is variable depending on androgen production. A diagnosis of PGD is based on clinical/biochemical features, gonadal histology and genetic findings. The aim of this study is to characterise these features, particularly histological, in a lar...

Background: Skeletal dysplasias comprise heterogeneous disorders often characterised by short stature with abnormalities of one or more of epiphysis, metaphysis or diaphysis. Over 200 types of skeletal dysplasias are identified, most of which are autosomal dominantly inherited. Actually, surgery has attempted to correct bone deformities but drug therapy for improving their severe short stature has been rarely attempted.Objective and hypotheses: Administr...

Background: Congenital Hyperinsulinism (CHI) is the most common cause of recurrent and severe hypoglycaemia in childhood and can be broadly categorised into two subtypes. Diffuse CHI (CHI-D) involving all pancreatic cells is usually treated with medications and rarely subtotal pancreatectomy. Focal CHI (CHI-F) involves a solitary insulin hypersecreting pancreatic lesion and can be cured following surgical lesionectomy. Many patients with CHI-F and CHI-D underg...

Background: Most published studies on 46,XY DSD focused on genetic findings without association with biochemical work-up.Objectives: To retrospectively analyze the clinical and genetic findings of a large cohort of 46,XY DSD patients.Methods: 285 non-syndromic 46,XY DSD individuals (192 sporadic and 89 familial cases) were studied. LH, FSH, testosterone (T), androstenedione (A) wer...

Background: 46,XY gonadal dysgenesis (GD) is a spectrum disorder which lead to variable degrees of atypical external genitalia, ranging from female to micropenis and absent of gonadal tissue (known as Embryonic Testicular Regression Syndrome -ETRS). Most patients with 46,XY GD remains without a molecular diagnosis.Objective: To report the DEAH-box helicase 37 gene (DHX37) as a novel candidate for the GD etiology.Patients a...

Abnormal DNA methylation contributes to tumor progression and is emerging as a prognostic marker in several types of cancers. To investigate whether DNA methylation is associated with pediatric adrenocortical tumor (pACT) presentation and patient prognosis, we analyzed the methylation profile of 57 tumors (MethylationEPIC BeadChip Array-Illumina) and patients’ clinicopathological features and outcome. The study comprehended 40 girls and 17 boys, with median age at diagnos...

Background: Childhood onset growth hormone deficiency (CO-GHD) may contribute to low bone mass and alterations of body composition. However, the mechanisms by which CO-GHD effects bone health are not yet clearly defined.Objective and hypotheses: To evaluate musculoskeletal health in CO-GHD subjects at initial evaluation and retesting after final height.Method: A cross-sectional study of assessing bone health and body composition by...

Background: Turner syndrome (TS) is one of the most common genetic disorders in females and occurs in phenotypic females who are missing all or part of one sex chromosome. While the most common mosaic forms of the disorder are 45,X/46,XX and 45,X/46,Xiq, mosaicism for cells containing Y chromosome material is well documented.Objective and hypotheses: Owing to increased risk of gonadoblastoma (GB), current recommendations are for elective gonadectomy foll...

Background: Secondary pseudohypoaldosteronism (PHA) type 1 is an uncommon salt losing condition of infancy caused by transient resistance of the mineralocorticoid receptors (MR) of the renal tubule to aldosterone. This can be secondary to urinary tract infection (UTI), urinary tract malformation (UTM) or obstructive uropathy. Ninety percent of reported cases present before 3 months and nearly all are under 7 months of age.Objective and hypotheses: The co...

Background: GH deficiency (GHD) occurs in one in 4000–one in 10 000 children, but can also be diagnosed in adults.1 GHD therapy typically requires injections over a period of years.2 Adherence to long-term GHT presents a challenge.Objective and hypotheses: This study describes the rates of adherence to GHT among patients with GHD.Method: Members who were continuously enrolled 6 months pre- and 12 months p...
