Introduction: Debate still exists about the safety of long-term use of prednisone (P) versus hydrocortisone (HC) for treating children with congenital adrenal hyperplasia -21OH D (CAH).Aim: To investigate the linear growth and weigh gain as well as metabolic component in children with CAH who were treated with either HC or P since early infancy for 5 years or more.Methods: Data of ...

Objectives: Thiamine responsive megaloblastic anemia syndrome (TRMA) is characterized by the clinical triad of megaloblastic anemia, non-immune diabetes mellitus and sensorineural deafness. It is a very rare autosomal recessive disease with an increased frequency in consanguineous marriages and isolated communities. The syndrome is due to intracellular thiamine deficiency which is the result of a defective high affinity low performance thiamine transporter pro...

Background: Familial Hypercholesterolaemia (FH) is a common autosomal dominant disorder of low-density lipoprotein (LDL) metabolism characterised by elevated levels of plasma LDL-cholesterol (LDL-C), accelerated atherosclerosis and premature cardiovascular disease (CVD). In the Gulf Co-operation Council states, CVD is often diagnosed at a younger age and is the leading cause of mortality. As such, early genetic diagnosis and treatment of FH is important for ri...

Background: Advances in genetic analysis techniques has greatly contributed to recent discovery of causative genes associated with overgrowth with intellectual disability (OGID). Tatton-Brown-Rahman syndrome (TBRS) (OMIM #615879) was one of them, characterized by tall stature, a distinctive facial appearance, and intellectual disability. This syndrome was first reported in 2014. Thus, long-term clinical courses are unknown. We present our Japanese case with OGID who was diagno...

Background: Gonadal dysfunction is one of the major endocrinological late effects among cancer survivors. Chemotherapeutic agents and radiation are so gonadotoxic that ovarian reserve diminishes. Measurement of anti-müllerian hormone (AMH) concentration is useful as a marker of ovarian reserve or gonadal deficiency in female childhood cancer survivors (CCSs), particularly among patients without high gonadotropin levels.Objective and hypotheses: The ...

Type II collagenopathy is a generic name of the skeletal dysplasia caused by COL2A1 gene, such as achondrogenesis type II, spondyloepiphyseal dysplasia (SEDC), spondyloepimetaphyseal dysplasia (SEMD). Since this is a rare disease, genotype-phenotype characteristics is still unclear. Here, we describe the genotype-phenotype characteristics of four families of type II collagenopathy in our hospital. Family 1: the proband was 2-year-old girl. She showed severe short stat...

Background: Septo-optic dysplasia (SOD) is a rare disorder characterized by optic nerve hypoplasia, anterior midline abnormality and pituitary hormone deficiency. Mutations of several genes are known to cause SOD related condition, such as HESX1, SOX2, SOX3, and OTX2, but mutations of WDR11 has not been reported in SOD.Objective: Reporting the first SOD patient identified a mutation in WDR11.<p cl...

Background: WDR11 has recently been reported as one of the causative genes of hypogonadotropic hypogonadism (HH). To date, five missense mutations in WDR11 have been identified in six patients with normosmic isolated HH (nIHH) or Kallmann syndrome (KS).Methods: We performed mutation screening of WDR11 for 46 cases with various types of HH. RT-PCR was carried out for a patient with a mutation. The protein structure of the mutant...

Background: While existing guidelines recommend long-term follow-up of childhood cancer survivors (CCS), transitional care among pediatric and adult endocrinologists has not been established in Japan.Objective and Hypotheses: To know the present situation and to cultivate a better understanding, we had conducted a nation-wide survey targeting Japanese pediatric endocrinologists.Method</stro...

Background: While existing guidelines recommend long-term follow-up of childhood cancer survivors (CCS), their fertility has not been clarified in Japan.Objective and hypotheses: To address this issue, we organized a working panel to compile evidence from CCSs. The team consisted of various medical specialists in foundation hospitals.Method: We had conducted the questionnaire surveys targeting pediatric endocrinologists regarding r...
