Background: Thyrotoxic periodic paralysis (TPP) is a rare clinical manifestation of hyperthyroidism, commonly seen in Asian males. Patients often present with sudden onset muscle weakness associated with severe hypokalemia.Case presentation: A 16-year-old Filipino male presented with acute onset bilateral lower extremities weakness. He woke up at night but was unable to move his legs. He denied any recent viral infections, ingestion of canned food or his...

Background: Silver Russell syndrome (SRS) is an imprinting defect disease.Objective: To study clinical characteristics and imprinting defects in Chinese children with SRS.Methods: Forty-nine SRS cases were studied retrospectively. Out of these 49 cases, 36 were available to be detected chromosome 11p15 imprinting defects and 21 cases were detected uniparental disomy of maternal chromosome 7 (UPD(7) mat).Resul...

Background: The growth pattern of normal children was inappropriately used to evaluate those who with DSD.Objective: To understand growth and development of the 46, XY disorders of sex development (DSD) children, drawing height, weight and BMI curve of children with 46, XY DSD at the age of 0–16.Method: The registration database was used in this study. Non- CAH 0-16 years old 46, XY DSDs were collected. Growth curves were fitt...

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: The initial L-T4 dose currently recommended in the treatment of congenital hypothyroidism (CH) is 10–15 mcg/kg per day.Objective and hypotheses: We designed a multicenter randomized trial to evaluate the effects of different starting doses of L-T4 within the range 10–15 mcg/kg per day on neurocognitive development in children with CH.Method: Seventy-two children with CH diagnosed by neonatal screening were enr...

Objective: To evaluate the response to recombinant human GH (rhGH) treatment in NS children with short stature and previously identified mutations in the RAS/MAPK pathway genes.Methods: 23 patients with NS (17 males; 19 PTPN11, 3 RAF1 e 1 SHOC2) were daily treated with rhGH (mean rhGH dose of 47 μg/kg per day). The main outcome measures were 1st year growth velocity, change in height SDS (Noonan syndrome specifi...

Introduction: Noonan syndrome (NS) is a relative frequent genetic disorder, mainly characterized by dysmorphic face features, congenital heart defects and short stature. Though delayed pubertal development has been described in both sexes, the physiopathological root remains unclear. This study aims at characterizing puberty development in Noonan syndrome.Materials and Methods: The study population included 111 individuals with a molecul...

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...
