Background: Prader-Willi Syndrome (PWS), due to loss of paternal gene expression on chromosome 15q11.2-13, is characterized by hypotonia, hypothalamic-pituitary dysregulation, abnormal respiratory drive, and hyperphagia. GH, often started in infancy, improves tone, body composition, and height. Concerns about sudden death in children with PWS started on GH, hypothesized secondary to worsening obstructive sleep apnea (OSA) from adenotonsillar hypertrophy, resulted in guidelines...

An association between Turner syndrome (TS) and Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency is rare. TS is caused by partial or complete loss of the second sexual chromosome which leads to genital system malformation and infertility. 21-hydroxylase deficiency is a well-known cause of disorder of sexual development in genotypic female neonates.The aim of our study is to report this patient and stress this rare possibility. A 8-month-old patient sufferi...

Objectives: To investigate the effect of Letrozole on the reproductive function and linear growth in adolescent boys.Methods: 43 early and middle pubertal boy with seriously damaged predicted adult height(PAH), treated with letrozole 1.5mg/m2/d Po(≯2.5mg/d) with a duration of 3-18 months were enrolled as Short-, medium- and long- treatment group with letrozole of 3-6, 6-12, 12-18 months, respectively. 48 healthy pubertal boys were enrolled as control...

Objectives: To summarize the clinical manifestations of a patient of 46,XY partial gonadal dysgenesis (PGD) accompanied by neuropathy. This is the first reported case of DHH mutation from China.Methods: We retrospectively reviewed the case and summarized the clinical history, physical examinations, laboratory and genetics tests, electromyography, ultrasound, surgical exploration and histopathology results.Results: The 14.3-year-old...

Background: Prader-Willi Syndrome (PWS), due to loss of expression from genes within the PWS imprinted region at chromosome 15q11.2-13, is characterized by hypotonia and feeding intolerance in infancy with later development of hyperphagia and obesity. Growth hormone improves tone, body composition, and height and can be started in infancy. Morbidity and mortality in PWS include those secondary to hyperphagia and respiratory illness as well as a 17% reported incidence of sudden...

Background: Non-alcoholic fatty liver disease (NAFLD) is a common chronic liver disease in both children and adults; however, the exact pathogenesis of NAFLD remains obscure. Accumulating evidence supports the effects of miRNA in the lipid metabolism and the regulation of insulin resistance, providing a potential linkage between the miRNA and NAFLD.Objective and Hypotheses: The aims of this study were to explore microRNA (miRNA) expression profiles in NA...

Background: The gold standard for adequate hormonal suppression during GnRHa treatment for precocious puberty (PP) is attenuated serum LH levels in response to LHRH stimulation.Objective and hypotheses: We aimed to compare basal and post-GnRHa levels of LH to LHRH stimulation test, and to evaluate first-voided urinary LH (ULH) as a non-invasive alternative method for monitoring treatment.Method: Seventeen girls with PP were followe...

Background: Management of transient neonatal diabetes mellitus is complex. Conventional insulin therapy may be increase additional medical problems. From the case is presented, We suggested s.c. insulin pump therapy of neonatal diabetes is a safe and effective approach to management.Objective and hypotheses: To evaluate the therapeutic effect of continuous s.c. insulin infusion with insulin pump in a case with transient neonatal diabetes mellitus (TNDM)....

Background: Congenital hypothyroidism (CH) is a major target of new born screening. It has two major forms (permanent and transient) that have different prognoses.Objective and hypotheses: The purposes of this study were to assess the trends in incidence of permanent and transient CH in China, and to identify clinical variables that may help to distinguish these two forms of CH.Method: Newborns were screened for CH at Xinhua Hospit...

Background: In developing countries, due to the lack of medical resources, it is necessary to do the preliminary diagnosis of Bartter syndrome and Gitelman syndrome according to the existing clinical data rather than the genetic testing. Is clinical diagnosis consistent with the gene diagnosis?Objective and hypotheses: To summarise the children’s clinical features, furosemide/hydrochlorothiazide loading test and genotype of Bartter syndrome and Gite...
