Combined Surgical and Medical Treatment in an Adolescent with Severe Gynecomastia Due to Excessive Estradiol Secretion: A Case Report

Lee Miseon , Moon JungEun , Woo Ko Cheol , Seok Lee Joon , Dug Yang Jung

Background: Gynecomastia develops due to the reversed estradiol-to-Testosterone ratio in adolescence, and symptoms typically improve within two years. The causes vary widely, including estrogen excess and tumors, and surgical treatment is usually given in late adolescence because postoperative symptoms may recur in adolescents. There are no guiding recommendations for gynecomastia to date besides the suggestion to consider rapidly growing gynecomastia and brea...

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...

Clinical and Endocrine Characteristics and Genetic Analysis of Korean Children with McCune–Albright Syndrome

Cho Eun-Kyung , Im Minji , Kim Jinsup , Yang Aram , Song Ari , Ki Chang-Seok , Lee Ji-Eun , Cho Sung Yoon , Jin Dong-Kyu

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...

Kim Insung , Hwang JiHoon , Sung Juyoung , Eun Kim Sung , Lee Dong-Yun , Kim Min-Sun , Yoon Cho Sung , Jin Dong-Kyu , Seok Choi Doo

Introduction: Estrogen treatment can be used for pediatric patients with Marfan syndrome who wish to control the rate of excessive height growth. However, the appropriate timing of treatment initiation is controversial and studies were limited. In this study, the authors aimed to find out when the initiation of estradiol therapy is most appropriate for controlling height growth rate in patients with Marfan syndrome.Methods:</stro...

Genetic spectrum of 26 Korean patients with congenital hypothyroidism by targeted next-generation sequencing

Oh Arum , Han Heon-Seok

Introduction: Congenital hypothyroidism (CH) is caused by underdeveloped thyroid gland or defect of thyroid hormone synthesis. The prevalence of CH in Korea is 1 per 4,225 people, and DUOX2 mutations were previously known as the most prevalent mutation in Korean patients with CH. This study was performed to identify the correlation between etiology and genetic mutations in patients with CH in a single tertiary hospital.Methods:</...

A case of a newborn diagnosed with CMAMMA suspected of primary immunodeficiency

Oh Arum , Han Heon-Seok

Background and Aims: Combined malonic and methylmalonic aciduria (CMAMMA) is a rare genetic disorder that affects the body's ability to break down certain proteins and fats. It is caused by mutations in the ACSF3 gene, which provides instructions for making an enzyme involved in the metabolism of fatty acids. As a result of the enzyme deficiency, individuals with CMAMMA experience an accumulation of malonic and methylmalonic acids in their blood and urine...
