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...

Background: As a curative therapy, haematopoietic stem cells transplantation (HSCT) has been also used for patients with non-neoplastic diseases such as aplastic anemia, primary immunodeficiency, and some congenital metabolic diseases. For these diseases, the intensity of the conditioning has been reduced comparing to that of malignancy diseases. Therefore, late effects of HSCT for non-neoplastic diseases has been expected to be milder than that for neoplastic diseases, howeve...

Background: Haematopoietic stem cell transplantation (HSCT) is a risk factor for young adult onset diabetes mellitus (DM) and hyperlipidaemia (HL) as late effects, especially the use of total-body irradiation (TBI). In order to investigate the clinical details, we retrospectively analysed the post-HSCT patients in our institution that required treatment for DM and/or HL.Results: From 1983 to 2012, 24 children received HSCT in our hospital because of haem...

Background: N-acetylneuraminic acid synthetase-congenital disorder of glycosylation (NANS-CDG) is a recently established rare autosomal recessive disease caused by pathogenic variants in NANS involved in the biosynthesis of N-acetylneuraminic acid (the most common member of sialic acids). Sialic acids are ubiquitously distributed in the body including the brain and skeletal system, and are required for the development and function of multiple organs/tissues. C...

Background: Reference values for penile length have not been established for Japanese boys.Objective: We aimed to develop percentiles and means with standard deviations of stretched penile length (SPL) in Japanese boys.Method: We conducted a cross-sectional study in 1 628 Japanese boys aged <9 years from 2007 through 2014. The LMS method was used to develop a growth reference and chart for SPL in boys aged 0–7 years. Inter...

Background: Aromatase excess syndrome (AEXS) is a rare autosomal dominant disorder caused by the overexpression of CYP19A1 at 15q21. Patients with AEXS manifest various clinical features associated with oestrogen excess; gynecomastia, hypogonadotropic hypogonadism, and advanced bone age are the most salient features in this condition.Objective and hypotheses: The primordial treatment of the gynecomastia in patients with AEXS is surgical mastecto...

Objectives: This trial (NCT01927861) evaluated the growth-promoting effect and safety of Norditropin® (somatropin; recombinant human growth hormone) in Japanese children with short stature due to Noonan syndrome over four years of treatment.Methods: Pre-pubertal children diagnosed with Noonan syndrome were randomized 1:1 to receive Norditropin® 0.033 mg/kg/day or 0.066 mg/kg/day. Change in...

Back ground: The incidence rate of vitamin D deficiency is increasing throughout the world in recent years, but the rate of vitamin D deficiency in Japan is unknown.Aims: We measured the incidence rate of vitamin D deficiency in 12-year old children in Japan.Methods: A total of 492 children (247 boys and 245 girls) from one Japanese community enrolled in this study. At age 12, 25 hydroxyvitamin D (25OHD) were measured in all childr...

Introduction: Obesity is one of common complications in achondroplasia (ACH) and hypochondroplasia (HCH). Obesity can be a risk factor for excessive load on joints or lower spines in aged, worsen sleep apnea and develop a metabolic syndrome. Thus, it is critical to maintain their proper weight from early childhood. ACH specific growth charts and BMI has been used to evaluate their overweight and obesity. Due to disproportional short stature, the assessment by BMI could lead an...

Background: The type I IGF1R plays a role in intrauterine and postnatal growth. Heterozygous IGF1R mutations have been identified in over 20 families. Some of them are linked to the etiology of short stature in previous studies. In addition, we previously reported that a heterozygous nonsense mutation (p.Q1250X) of the IGF1R gene led to decrease IGF1R protein expression through endoplasmic reticulum-associated protein degradation (ERAD) mechanism, resulted in...
