Background: The effects of GH deficiency (GHD) and GH replacement therapy (GHRT) on body composition and functional measures of physical fitness are largely unknown particularly in children.Study aim: To evaluate body composition, muscular strength and flexibility, and exercise tolerance in GHD children at baseline and after one-year GHRT.Patients and methods: We enrolled 19 children and adolescents with untreated ...

Background: Leptin is considered to play an important role in the development of hypertension in obesity. The excessive synthesis of aldosterone contributes to the development and progression of metabolic and cardiovascular dysfunctions. Leptin is a newly described regulator of aldosterone synthesis that acts directly on adrenal glomerulosa cells to increase CYP11B2 expression and enhance aldosterone production in human adrenal cells lines and in animal models.<p class="ab...

Primary hyperparathyroidism is a condition characterized by one or more hyperfunctioning parathyroids leading to hypercalcemia and inappropriately normal or elevated levels of parathyroid hormone (PTH). Clinically it can occur asymptomatically or manifests with osteopenia, increased risk of pathological fractures, nephrolithiasis, gastrointestinal symptoms (vomiting, constipation, abdominal pain) or asthenia. We report the case of A.L.M, a 15-year-old female who went to the Em...

Introduction: Septo-optic dysplasia (SOD) is an uncommon, highly heterogeneous entity of multifactorial etiology, consisting in the association of 2 or more of the following characteristics: ophthalmological abnormalities [most frequently optic nerve hypoplasia (ONH)], midline brain abnormalities [such as aplasia/hypoplasia of the septum pellucidum (SP) and/or corpus callosum (CC)] and variable degree of hypotalamo-pituitary insufficiency (HPI)<p class="ab...

Wolf-Hirschhorn syndrome is a genomic disorder caused by 4p16.3 deletion with facial dysmorphology, growth retardation, developmental/intellectual delay and seizures. After 165 kb critical region encompassing NSD2 was identified, most recently, three NSD2 loss of function variants was uncovered in patients with overlapping phenotype with Wolf-Hirschhorn syndrome. In our study, a NSD2 variant, c.1577dupG (p.Asn527fs*14) was identified in two patie...

Objective and hypotheses: The purpose of this research is to establish reference intervals for the steroid hormones of 6 to14 year-old normal male children using LC-MS method; study the variation pattern of steroid hormones in terms of different ages and Tanner stages of puberty.Method: A total of 1175 male children from 6 to 14 years old from Shunyi District, Beijing, have participated in this research, with 820 children determined as normal-weight. Pre...

Background: Bartter syndrome (BS) and Gitelman syndrome (GS) have similar clinical manifestations. It’s hard to be distinguished by the symptoms and laboratory, even though the genetic analysis cannot identify them precisely. The precise diagnoses associate with the right treatment and prognosis. Hypercalciuria usually involved with neonate type Bartter syndrome, and hypomagnesemia with Gitelman syndrome.Objective a...

Background: SRS is a typical epigenetic disease. Approximately 40% of patients can not be detected genetic and epigenetic disturbances.Objective and hypotheses: To analysis whether there is unknown genes or imprinted genes associated with pathogenicity of SRS and to detect the fine mapping SRS hypomethylation position through the Illumina Methylation 450K chip to detect genome-wide methylation differences.Method: To detect genome-w...

Background: We investigate the efficacy and safety of two different treatments which have not been evaluated in peri-puberty boys with HH.Objective and hypotheses: To assess the effectiveness and safety of pulsatile GnRH or hCG treatment in adolescent boys with hypogonadotropic hypogonadodism.Method: 12 patients received 8–10 μg of GnRH, subcutaneously injected every 90 min using a pump. Another 22 patients received hCG, ...

Background: Nearly half of SRS epigenetic etiology is unknown. Effect of GH in SRS is not exact.Objective: To determine novel gene or imprinted gene associated with pathogenicity of Silver–Russell syndrome (SRS) through detection genome-wide methylation differences. To observe GH efficacy in SRS and the relationship between GH and epigenetic changes.Method: To detect genome-wide methylation site through the Illumina 450K methy...
