Case: The case is a 19-year-old woman. Her chief complaint is primary amenorrhea. She was born at 40 weeks of gestational age. Birth weight was 2456 g and birth height was 47 cm and she was admitted to the hospital due to abnormality of facial formation, post-nasal cavity closure and respiratory disorders. Her motor development was delayed (standing at 3 years old, walking at 5 years old) and she underwent plastic surgery for 6 times. On admission her height was 151.6 cm (&#87...

Molecular Genetic Diagnosis of Idiopathic Hypogonadotropic Hypogonadism by Using Targeted Next-Generation Sequencing

Aoyama Kohei , Suzuki Atsushi , Tanaka Tatsushi , Mizuno Haruo , Saitoh Shinji

Background: Idiopathic hypogonadotropic hypogonadism (IHH) is a congenital heterogeneous disorder characterized by a deficiency of gonadotropin-releasing hormone. IHH can be categorised as IHH with anosmia/hyposmia (Kallmann syndrome: KS) or as normosmic (n)IHH. More than 25 genes have been identified in IHH. Nevertheless, patients with IHH are genetically diagnosed in only less than 50%.Objective: The objective of this study is to confirm the applicatio...

A Case of Wiedemann–Steiner Syndrome with Central Precocious Puberty

Aoyama Kohei , Yoshida Aya , Yamaguchi Naoya , Suzuki Atsushi , Tanaka Tatsushi , Saitoh Shinji , Mizuno Haruo

Background: Wiedemann–Steiner syndrome (WSS) is a rare autosomal dominant disorder characterized with hypertrichosis cubiti, dysmorphic facial appearance (hypertelorism, thick eyebrows, and narrow palpebral fissures), psychomotor delay, and short stature. WSS is caused by a mutation in the KMT2A gene. The timing of secondary sexual characteristics in patients with WSS is not well known. To our knowledge, two patients (one boy and one girl) with W...

A Successful Switch Experience from High-dose PTU to MMI on Day 4 of Graves’ Thyroid Storm in a 14-Year-Old Girl

Shinohara Hiroyuki , Iwabuchi Atsushi , Yamada Akiko , Kai Tomomi , Kamoda Tomohiro

Background: The standard pharmacological treatment strategy of thyroid storm according to 2016 Japan Society of Pediatric Endocrinology Guideline. Although thiamazole (MMI) is recommended be used as the first choice in GravesÂ’ disease, the effect of propylthiouracil (PTU) to block the conversion from T4 to T3 in peripheral tissues encourages clinicians to use against thyroid storm in its very early phase, and switch to MMI later. Nevertheless, the optimal timing of the sw...

The Correlation between the Increase in IGF1 and the Growth Improvement Induced by GH Treatment in Short Children Born Small for Gestational Age

Hattori Atsushi , Eto Junya , Kawano Atsuko , Miyako Kenichi

Background: IGF1 is an important marker of GH treatment and is used to titrate the GH dose.Objective and hypotheses: We report the correlation between the GH treatment induced increase in IGF1 and growth improvement in short children born small for gestational age (SGA).Method: We recruited 13 pre-pubertal SGA children (eight boys, five girls) who received GH treatment. Eight continued treatment for >2 years. We retrospectively...

A Case Report of a 10-Year-Old Girl with Pituitary Abscess

Yoshida Aya , Oyachi Maki , Yamaguchi Naoya , Suzuki Atsushi , Aoyama Kohei

Background: Pituitary abscess is a rare disorder, representing less than 1% of pituitary lesions. Preoperative diagnosis is often difficult due to non-specific symptoms and image findings.Case Report: Here, we report the case of a 10-year-old girl with a pituitary abscess. She presented with polyuria and polydipsia and headache for the past year. Magnetic resonance imaging revealed polycystic lesion in the sella turcica ...

Diverse Phenotypes of Three Cases of Partial Androgen Insensitivity Syndrome with Androgen Receptor Gene Variants

Aoyama Kohei , Oyachi Maki , Yoshida Aya , Yamaguchi Naoya , Suzuki Atsushi , Mizuno Haruo , Saitoh Shinji

Background: Partial Androgen Insensitivity Syndrome (PAIS) is characterized by varying degrees of masculinization defects due to impaired androgen action, resulting in a wide range of physical and psychological phenotypes.Case 1: 18-year-old with a male social gender. The patient presented with hypospadias, micropenis, and cryptorchidism during the neonatal period, and received testosterone therapy during infancy, but sh...

Homozygous Loss-of-Function Mutation in the SLC26A7 Gene Coding a Novel Iodide Transporter Causes Goitrous Congenital Hypothyroidism

Introduction: Iodide transport in the thyroid is crucial for thyroid hormone synthesis. A homozygous loss-of-function mutation in the SLC26A4gene coding an iodide transporter located at the apical side in the thyroid follicular cells causes Pendred syndrome accompanied with goitrous congenital hypothyroidism (CH) and sensorineural deafness. However, about half of patients with Pendred syndrome demonstrate normal thyroid function. This indicates anothe...

The Dose Dependent Effect of Growth Hormone Therapy in Patients with IGF1 Receptor Haploinsufficiency due to Heterozygous Deletion

Mizuno Haruo , Aoyama Kohei , Tanaka Tatsushi , Saitoh Shinji

Background: The IGF1 receptor (IGF1R) gene is located on the distal long arm of chromosome 15 (15q26.3). Heterozygous inactivating mutations of the IGF1R gene cause intrauterine and postnatal growth failure and mental retardation.Objective: The purpose of this research is to determine the most effective GH treatment for patients with IGF1R haploinsufficiency due to heterozygous deletion.Method: We investigated the clinical course o...
