Background and Purpose: The prevalence of non-alcoholic fatty liver disease (NAFLD) in children has been increasing associated with insulin resistance. However, there is a scarcity of related studies in children with NAFLD with type 2 diabetes mellitus (T2DM) compared to adults. We conducted this study to investigate the association between non-invasive diagnostic methods of liver fibrosis and T2DM in pediatric patients with NAFLD.<stron...

1q21.1 recurrent microdeletion syndrome is a rare chromosomal disorder caused by a genetic abnormality of non-allelic homologous recombination in the sequence of flanking a copy number variation event during meiosis. The characteristic features of 1q21 microdeletion syndrome are dysmorphic facial appearances with microcephaly, and mild to moderate developmental delay of speech and motor, eye abnormality, short stature, skeletal malformation, and psychiatric and behavioral diso...

Background: Osteogenesis imperfecta (OI) includes a group of disorders with a susceptibility to bone fractures, the presentation ranging from slightly increased fracture frequency to death in the perinatal period.Objective and hypotheses: Autosomal-dominant inheritance with type I collagen biosynthesis defects is the most common, but many autosomal-recessive genes have been previously reported.Method: Whole-exome sequencing was per...

Background: Recombinant human GH (rhGH) therapy requires daily s.c. injections, this inconvenient treatment regimen results to poor compliance of the patient. Thus, to improve patient compliance, long-acting rhGH products including various protein fusion techniques have been in development during past 15 years.Objective and hypotheses: In this study, we describe the pharmacokinetics and efficacy of a novel long-acting GH using Fc fusion protein (rhGH-Fc)...

Background: GnRH agonists are a common treatment modality for patients with central precocious puberty.Objective and hypotheses: Danazol-induced precocious puberty rats were used as an animal model to compare the effects of GnRH analogues and to assess combinations of treatment with agonistic and antagonistic GnRH analogues.Method: A 5-day-old female Sprague–Dawley rats were subcutaneously injected with a single dose of 300 &#...

Introduction: Turner syndrome (TS) is caused by monosomy or structural abnormalities of the X chromosome, with a prevalence of out 1/2500 females live birth. Most important clinical features of TS are short stature and gonadal failure. Approximately one third of girls with TS may undergo spontaneous puberty. Here we report a case of a variant TS with breast development.Case report: A 9-year-old girl was referred to our paediatric endocrinology outpatient...

Prolactinoma is most common functioning pituitary adenoma(50%). However, there have been limited studies for prolactinoma in adolescents. Pituitary adenomas are uncommon in childhood and adolescence (<3% of childhood supratentorial tumors, 3–6% of all surgically treated adenomas). The aim of this study is to assess the characteristics of Korean adolescents with prolactinoma and their clinical course. This study is retrospective cohort study. Patients diagnosed with pr...

Background: Patients with Marfan syndrome (MFS) presents with primary skeletal manifestations such as tall stature, chest wall abnormality, and scoliosis. And these primary skeletal manifestations affect the growth pattern in MFS. Therefore, it is not appropriate to use normal growth charts to evaluate the growth status of MFS.Objective and hypotheses: We aimed to develop disease-specific growth charts for Korean MFS patients and to use these growth char...

McCune-Albright syndrome (MAS) is a rare disease defined by the triad of precocious puberty (PP), café au lait spots, and fibrous dysplasia (FD). There are only a few patients with MAS in Korean because of the rarity of this disease. We reported the various clinical and endocrine manifestations and genetic analysis of 14 patients with MAS in Korea. It is a retrospective cohort study of patients’ clinical data including about peripheral PP, FD. Also, treatment experie...
