Novel SLC34A1 Mutation in a Girl Infant with Idiopathic Infantile Hypercalcemia

Kang Seokjin , Kim Heung Sik

SLC34A1 encodes renal sodium-phosphate cotransporter 2A. It has been identified as being a part of the etiology of idiopathic infantile hypercalcemia. We report a case of a 1-month old girl, initially hospitalized due to perinatal detection of nephrocalcinosis. Blood tests showed hypercalcemia, hypophosphatemia, hypercalciuria and increased 1,25-(OH)2D3. Renal ultrasound revealed medullary nephrocalcinosis. An abnormality in vitamin-D metabolism was suspected and genetic testi...

Relation between Hypomagnesemia and Increased Level of HbA1c in Patients with Diabetes Mellitus

Kang Seokjin , Kim Heung Sik

Background: Hypomagnesemia is a frequent condition in patients with diabetes mellitus (DM). It could influence metabolic control in patients with DM. Relevant studies concern mainly adults and there are few data from the pediatric population. The aim of the present study was to evaluate magnesium levels and examine their possible association with glycemic control in pediatric patients with diabetes mellitus.Methods: In all, 36 patients with DM (type 1, 3...

Hypercalcemia Associated with Increased Parathyroid Hormone-related Protein (PTHrP) in a Patient with Medulloblastoma Successfully Treated with Pamidronate

Kang Seok Jin , Kim Heung Sik

We report a patient with medulloblastoma showing severe hypercalcemia and a raised PTHrP serum level. He was a 19-year-old with a history of recurrent medulloblastoma. He developed constipation, lethargy and altered mentality for 3 weeks. There was no family history of hypercalcemia. Laboratory test revealed hypercalcemia of 18.2 mg/dL. PTHrP increased to 10.7 pmol/L (normal range: <1.1 pmol/L), whereas serum level of intact parathyroid hormone was suppressed to 5 pg/mL (n...

A Case of Acute Suppurative Thyroiditis with Piriform Sinus Fistula Treated with Chemocauterization Using Trichloroacetic Acid

Son Kyung Lae , Kim Heung Sik

Case presentation: A 23 months-old girl visited the hospital because of fever and left neck mass. She was diagnosed as acute suppurative thyroiditis with piriform sinus fistula. Thyroid sonography showed perithyroidal abscess formation and thyroid scan showed decreased uptake of Tc-99 m pertechnate of both thyroid glands. Magnetic resonance imaging of neck suggested infected 3rd and 4th branchial cyst. And there was tiny fistula between thyroid and piriform sinus on barium eso...

Birth Anthropometry with Cord Blood Insulin-Like Growth Factor 1 and Leptin in Korean Appropriate-For-Gestational-Age Infants Born at ≥28 Weeks' Gestation

Kang Seok Jin , Kim Se Jin , Lee Ga Hyun , Kim Heung Sik

Background: We investigated the relationship of birth anthropometry with cord blood insulin-like growth factor 1 (IGF-1) and leptin levels in Korean infants born at ≥28 weeks' gestation.Methods: One hundred five appropriate-for-gestational-age (AGA) infants, defined as infants with birth weights (BWs) between the 10th and 90th percentiles for gestational age, were enrolled. Enrolled infants were stratified into...

Association Between Nonalcoholic Fatty Liver Disease and Growth Hormone Deficiency in Patients with Childhood-Onset Hypopituitarism

Kim Se Jin , Kim Heung Sik , Lee Ga Hyun , Kang Seok Jin

Background & Aims: Although, there has been reports demonstrating association between adult-onset hypopituitarism and development of nonalcoholic fatty liver disease (NAFLD), studies are lacking regarding the development of NAFLD in children and young adult with childhood-onset hypopituitarism. We aimed to identify association between NAFLD and hypopituitarism in these patients.Methods: 76 Korean children and young a...

Adult Height and Growth Pattern in Patients with Classic Congenital Adrenal Hyperplasia

Lee Ga Hyun , Kim Se Jin , Kang Seok Jin , Kim Heung Sik

Background: Congenital adrenal hyperplasia (CAH), mostly caused by 21-hydroxylase deficiency, is autosomal recessive disorder characterized by impaired cortisol synthesis. It can be presented with a combination of aldosterone and cortisol deficiency and androgen excess. Therefore, excess production of androgen and glucocorticoid replacement can result to early bone maturation and ultimately diminished adult height (AH).Objectives...

Novel Thyroid Hormone Receptor β-Gene Mutations in Resistance to Thyroid Hormone

Kim Heung Sik , Kim Se Jin , Kim Ga Hyun , Kang Seok Jin

The syndrome of resistance to thyroid hormone (RTH) is caused by decreased tissue responsiveness to thyroid hormone. With the exception, inheritance of RTH is autosomal dominant. The receptors are encoded by two genes (THRA and THRB), each of which undergoes alternate splicing to generate receptor subtypes (TRa1, TRβ1, and TRβ2), with differing tissue distributions.Here we describe a child with novel heterozygous mutations for THRB. Nine-months-old ...

Corticosteroid-Induced Adrenal Insufficiency in a Child with T Cell Lymphoblastic Lymphoma

Lee Sang Hyun , Son Kyung Lae , Sim Yeji , Kim Heung Sik

Background: Glucocorticoids play a major role in the treatment of lymphoblastic lymphoma. However, supraphysiological glucocorticoid therapy may cause the secondary adrenal insufficiency.Presentation of case: A 11-year-old boy with T cell lymphoblastic lymphoma, treated according to COG A5971 protocol, experienced sudden onset of tremor and general weakness in the first day after tapering 28 days of glucocorticoid therapy. He had a moon face and pigmenta...

A Case of Growth Hormone Deficiency with Combined Encephalocraniocutaneous Lipomatosis and Jaffe–Campanacci Syndrome

Choi Eun Mi , Shim Ye Jee , Kim Jun Sik , Kim Heung Sik

Introduction: Encephalocraniocutaneous lipomatosis (ECCL) is a rare neurocutaneous syndrome characterized by unilateral lipomatosis and ipsilateral neurologic/ophthalmic malformation. Jaffe–Campanacci syndrome (JCS) is characterized by the association of café-au-lait spots, axillary freckles, multiple non-ossifying fibromas of the long bones and jaw. Both of ECCL and JCS was associated neurofibromatatosis type 1. We had a case of GH deficiency with combined ECCL and ...
