Osteogenesis Imperfecta Type I Caused by a Novel Mutation in the Start Codon of the COL1A1 Gene in a Korean Family and the Course of Pamidronate Treatment for 1 Year

Cho Sung Yoon , Jin Dong-Kyu , Yu Jae-Hong , Han Heon-Seok

Background: A 3-year-old boy appeared healthy at birth and did not experience any fractures until 12 months of age. Blue sclera, frequent fractures without adequate trauma, nearly normal stature, the absence of dentinogenesis imperfecta, no bony deformity, and no limitation of mobility were characteristics suggestive of OI type I that were observed in the patient. The patient’s mother had blue sclera and a history of frequent fracture episodes until the age of 15 years.</...

Hypothalamic Obesity in Children with Craniopharyngioma: Prevalence and Risk Factors of Obesity and Longitudinal Trends of BMI

Cho Ja Hyang , Kim Ja Hye , Kim Yoo-Mi , Choi Jin-Ho , Yoo Han-Wook

Background: Craniopharyngioma is the most common parasellar tumor in childhood arising from remnants of Rathke’s pouch. As the hypothalamus plays a vital role in regulation of body weight by balancing energy intake and expenditure, hypothalamic damage by structural lesions is one of the most common causes of hypothalamic obesity. This study investigated prevalence, risk factors for the development of hypothalamic obesity, and consequent morbidities in children following t...

A Korean Boy with Pseudohypoparathyrodism Type Ia Presenting with Congenital Megacolon and Spinal Stenosis: Identification of a Novel GNAS Gene Mutation

Lee J E , Lee S H , Cho S Y , Ki C S , Jin D K

Pseudohypoparathyroidism (PHP) is a disease of rare frequency. There are five subtypes with each having different phenotypes and blood laboratory test results, which depend on gene mutation and hereditary styles. Among them, the most common type is PHP Ia which inherits maternal gene mutation and expresses Albright’s hereditary osteodystrophy (AHO) appearance, hypocalcemia, hyperphosphatemia and serum parathyroid hormone elevation. Another type, pseudo-pseudohypoparathyro...

Response of GH Therapy in Six Children with Achondroplasia

Kim Yoon Jung , Cho Byung Wook , Kim Ji Yoon , Kim Heung Sik , Lee Hee Jung

Background: Achondroplasia is the most common condition characterized by disproportionate short stature. Patients with achondroplasia progressively fall below normal standards for length and height. GH has been widely used to treat short stature with or without GH deficiency (GHD).Objective and hypotheses: The purpose of the present study was to clarify the effectiveness of GH therapy on short stature in achondroplasia.Method: The ...

Novel Compound Heterozygous BMP1 Variants Associated with Osteogenesis Imperfecta

Yang Aram , Huh Rimm , Kim Jinsup , Cho Sung Yoon , Jin Dong-Kyu

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...

Pharmacokinetics and Efficacy of a Long-Acting Human GH with Fc Fusion Protein

Kim Sujin , Jin Dong-Kyu , Cho Sungyoon , Huh Rimm , Kim Jinsup , Yang Aram , Kwak Hyunhee

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)...

Effects of GnRH Agonists and Antagonists on Danazol-Induced Precocious Puberty Rat

Yang Aram , Huh Rimm , Kim Jinsup , Cho Sung Yoon , Jin Dong-Kyu

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 &#...

Simultaneous Occurrence of Thyroid Storm, Diabetic Ketoacidosis, and Multiple Cerebral Infarction in a 16-Year-Old Girl

Park So-Eun , Noh Byoungho , Cho Sang-Won , Ahn Sung Yeon

Background: Diabetic ketoacidosis is one of the precipitating factors that can evoke a thyroid storm. Thyroid storm may cause cerebral ischemia in moyamoya disease, which coexist in the patient with Graves’ disease.Case presentation: A 16-year-old girl complaining of dizziness and palpitation visited emergency room, and was diagnosed with diabetic ketoacidosis (DKA) combined by hyperthyroidism. Thyroid storm occurred in 6 h after the start of DKA ma...

Turner Syndrome with Breast Development: Case Report

Park Sung Won , Cho Sung Yoon , Kim Jinsup , Huh Rimm , Kim Su Jin , Jin Dong-kyu

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...

Outcomes of growth hormone treatment in children with Prader Willi Syndrome over a 30-year period at the Children’s Hospital at Westmead, New South Wales Australia

Gamage Dilhara , Chan Albert , Maguire Ann , Srinivasan Shubha , Ambler Geoffrey , Hi Cho Yoon

Background: Prader-Willi syndrome (PWS) is a rare genetic obesity syndrome associated with relative growth hormone deficiency. Scoliosis is a known association of both PWS and growth hormone therapy (GH), although its role in causation remains uncertain. In the literature, short-term and long-term data revealed no adverse effects of GH on scoliosis. As the metabolic and clinical benefit of growth hormone therapy is established in the management of PWS, it is d...
