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 Graves’ 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...

Background: Although thiamazole (MMI) is the first-line treatment for non-pregnant women with Graves’ disease, the teratogenic effects of this drug have been confirmed. Surgical anomalies known as ‘major MMI-related anomalies’ include omphalomesenteric duct remnants. This is a common difficulty when attempting to clarify whether there is any association between infrequent surgical anomalies and MMI exposure using data derived from women with Graves’ disease...

Introduction: The Sonic hedgehog (SHH) signaling pathway plays a crucial role in development of the forebrain and pituitary. Mutations in SHH signaling related genes are well known to be the cause of Holoprosencephaly (HPE), which results from developmental field defect or impaired midline cleavage of the embryonic forebrain, and is frequently associated with hypopituitarism. This study aimed to define the prevalence of congenital hypopituitarism (CH) in terms...

Background: Mutations in HESX1, SOX3 responsible for combined pituitary hormone deficiency (CPHD) have been identified in a small number of hypogonadotropic hypogonadism (HH), suggesting that the genetic overlap between CPHD and HH.Case presentation: A 2-month-old boy was referred because of micropenis (stretched penile length 1.0 cm) with intrascrotal testes (1 ml). Hormone assays revealed very-low plasma testosterone levels (0.06 ng/m...

Background: GLI2 is a transcription factor in Sonic Hedgehog signaling and implicated in ventral forebrain and pituitary development. GLI2 mutations were reported not only in patients with holoprosencephaly but also in patients with pituitary hormone deficiencies without holoprosencephaly. Other phenotypes of GLI2 mutations are midline facial defects, cleft hands and feet, and polydactyly. We report two patients with combined pituitary hormone defici...

Background: Concerns about a child's growth are one of the most common topics parents express during pediatric visits and are a leading cause for referral to a pediatric endocrinologist. For the general pediatric, when short stature is diagnosed, its clinical management remains a challenge.Objective: The aim of the study was to approach and understand the perception from the general pediatrician about short stature,...

Introduction: Denosumab is an inhibitor of receptor activator of nuclear factor kappa-B ligand that strongly suppresses differentiation and function of osteoclasts. Cherubism is a rare autosomal dominant disorder characterized by symmetrical swelling of the mandible and the maxilla. In patients with cherubism, the bone is replaced by a fibrous granuloma containing multinucleated giant cells, which are differentiated into activated osteoclasts<p class="abst...

Background: Interstitial deletions of the short arm of chromosome 11 are rare chromosomal anomalies, and are considered to be associated with several clinical conditions including WAGR syndrome.Objective: To report the clinical and molecular findings in the first case of a heterozygous 11p14.1-p15.3 deletion.Patient: A Japanese female patient was born at 39 weeks of gestation after an uncomplicated pregnancy and delivery. At birth,...

Case presentation: A 2-year-boy was referred tour hospital for the rickets. He was the first son between non-consanguineous parents and fed with breast milk. But after weaning, he was avoided from taking egg, dairy products including cow’s milk. He was also suffered from developmental delay and had strong food preference. He could take only two kinds of foods, steamed rice and soy bean product, tofu. X-ray findings showed typical rachitic change on long bone metaphysis. L...

Norditropin® was approved for children with short stature due to NS in Japan in 2017. The aim of this post-marketing surveillance study was to evaluate long-term safety and effectiveness of Norditropin® for the approved indication. This real-world non-interventional study (NCT03435627) was conducted February 2018–January 2022. Seventy patients enrolled: 35 received Norditropin® after study initiation (new patients); 35 were previously ra...
