Background:In children and adolescents suffered form primary intracranial germ cell tumors, bifocal GCTs are rare and were reported a bad prognosis. In this study, we report a case and summarize the clinical characteristics and prognosis.Methods: A boy suffered form bifocal GCTs (Basal ganglia and pineal region) was diagnosed in our hospital and accepted chemotherapy+radiotherapy, and was followed up.<p class="abstex...

Background: Precocious puberty in girls may result in loss of FAH, and particularly may relates to obesity when entering adulthood. However,The influence of the timing of pubertal onset on the FAH and the change of body weight during pubertal stages is still controversial.Objective: The research is to investigate the pubertal growth pattern and the change of BMI levels in girls with ICPP and those who have normal onset of puberty but at different ages.</...

Background: Because ghrelin is closely linked to insulin resistance and type 2 diabetes mellitus in adults, ghrelin might also participate in the development and progression of pathological changes in insulin resistance in SGA infants.Objective and hypotheses: This study aimed to determine insulin sensitivity index (ISI), variation in ghrelin levels, and their relationship in small for gestational age (SGA) rats.Method: The SGA ani...

Background: Ovarian adrenal rest tumours (OARTs) are rare in contrast to testicular adrenal rest tumours (TARTs).Objective and hypotheses: To summarise the characterization of OART in children and adolescent females with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD).Method: We have diagnosed four cases of CAH 21-OHD with OART in the recent 5 years and summarised the characterisations.<p class="a...

Background: Tamoxifen is a selective estrogen receptor modulator，administrated in girls with precocious puberty such as McCune-Albright syndrome.Objective: To explore the effect of tamoxifen on the linear growth of precocious pubertal female rats.Method: At 16-22 day of age, 16 precocious pubertal female rats(induced by 300 μg danazol s.c. at 5-day old), were randomized...

Background: McCune-Albright Syndrome(MAS）is a rare disease caused by somatic gain-of-function mutations of the GNAS gene, presenting with fibrous dysplasia(FD), cafe-au-lait spots and gonadotropin-independent precocious puberty(PP). Adenohypophyseal hyperfunction syndromes is reported uncommon but potentially severe complication of MAS.Method: A prospective study was performed to evaluate the prevalence of the pit...

Background: Hepatoblastoma is the most common malignant pediatric hepatic tumor virtually confined to infants and young children. Accompanied by raised levels of alpha fetoprotein (AFP)，rarely, the beta human chorionic gonadotropin (β hCG) levels may also be elevated, which can cause male peripheral precocious puberty (PPP).Objective: To report a case of HB presented with PPP with elevated serum AFP, β h...

Background: In children with extracranial germ cell tumors (GCTs), brain metastases are rare and are classified as “poor prognosis”. The longest interval to brain metastases was 36 months after diagnosis in children, however, it is still less understood.Methods: We report a boy who had suprasella tumor recurrence 4 years after the first diagnosis of extracranial GCTs (thymus).Re...

Background and Aims: A novel bioactive peptide, mitochondrial-derived peptide (MOTS-c), has recently attracted interests as a potential prevention or therapeutic option for obesity and type 2 diabetes mellitus in mice. MOTS-c profiles have not yet been reported in type 1 diabetes (T1DM). We aimed to determine circulating MOTS-c levels in T1DM and explore the association between MOTS-c levels and various metabolic parameters.Metho...

Objective: We sought to evaluate the role of long-term HRT on the lipid profile and glucose metabolism in girls with TS.Design: A pre-test/post-test observational study.Seting: Pediatric TS clinic in The First Affiated Hospital, Sun Yat-sen University.Patients: 56 girls with TS had accurate maintenance HRT data....
