Congenital adrenal hyperplasia(CAH)due to 21-hydroxylase deficiency (21-OHD) is an inherited autosomal recessive disorder. Its incidence is 1 in 10,000 to 20,000 worldwide. This disease shows phenotypic differences, and it is divided into three forms i.e., the salt wasting (SW), simple virilizing (SV), and nonclassic (NC) forms. The most severe form of SW manifests in the first months of life with life-threatening adrenal insufficiency, leading to death. To prevent death by adrenal insufficiency in neonates with the SW form and wrong gender assignment of 46,XX female patients with SW and SV, neonatal mass screening of 21-OHD is performed in several countries including Japan. However, the positive predictive value (PPV) remains low, especially in preterm infants. To reduce the false positive rate and increase the PPV, liquid chromatography followed by tandem mass spectrometry (LC-MS/MS) as a second-tier test may be useful. In this review, the current knowledge on neonatal mass screening of 21-OHD is summarized.","PeriodicalId":10678,"journal":{"name":"Clinical Pediatric Endocrinology","volume":"25 1","pages":"1 - 8"},"PeriodicalIF":1.4,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1297/cpe.25.1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66287598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RTH is endocrinologically characterized by high serum thyroid hormones together with inappropriately normal TSH. The severity of hormonal resistance varies among different tissues in an affected individual, due to differences in the relative expression of TRβ and thyroid hormone receptor alpha (TRα) in different tissues (2).

The use of a GnRH agonist (GnRHa) in central precocious puberty (CPP) is known to slow puberty progression, subsequently prevent early menarche, and attenuate the height loss caused by advanced skeletal maturation. But enhancing the final height has been so controversial that an additional approach has been used. We investigated the menarcheal age and near final height (NFH) in girls with CPP treated with GnRHa (N = 61) or GnRHa combined GH (N = 24). GnRHa was started at 8.1 ± 0.7 yr and administered for 2.1 ± 1.0 years. GH was used for 2.1 ± 1.1 yr in subjects with a short predicted adult height (PAH). Menarche occurred at 11.6 ± 0.8 yr of age, which was 15.7 ± 6.4 mo after GnRHa discontinuation. PAH increased significantly from 152.0 ± 7.2 cm to 158.8 ± 5.6 cm during treatment, and the NFH (159.7 ± 4.8 cm) was taller than the midparental height (157.8 ± 3.4 cm). The combined treatment group showed a greater height increment during treatment. Younger age, taller height at the start of treatment, taller parental height and longer duration of treatment were the factors influencing NFH. In conclusion, GnRHa treatment in girls with CPP could improve NFH and delay menarche close to the general population. If GnRHa combined with GH is used in girls with CPP and a short midparental height, it would improve the NFH to a value similar to that in the general population.","PeriodicalId":10678,"journal":{"name":"Clinical Pediatric Endocrinology","volume":"24 1","pages":"175 - 183"},"PeriodicalIF":1.4,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1297/cpe.24.175","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66287968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main bone age assessment methods are the Greulich-Pyle and Tanner-Whitehouse 2 methods, both of which involve left hand and wrist radiographs. Several other bone age assessment methods have been developed, including ultrasonographic, computerized, and magnetic resonance (MR) imaging methods. The ultrasonographic method appears unreliable in children with delayed and advanced bone age. MR imaging is noninvasive; however, bone age assessment using MR imaging is relatively new, and further examinations are needed. An automated method for determining bone age, named BoneXpert, has been validated for Caucasian children with growth disorders and children of various ethnic groups. Sex hormones are necessary for bone growth and maturation in children with a bone age corresponding to normal pubertal age, and estrogen is essential for growth plate closure. Bone age is an effective indicator for diagnosing and treating various diseases. A new method for adult height prediction based on bone age has been developed using BoneXpert, in addition to the commonly used Bayley-Pinneau and Tanner-Whitehouse mark II methods. Furthermore, bone age may become a predictor for the timing of peak height velocity and menarche.","PeriodicalId":10678,"journal":{"name":"Clinical Pediatric Endocrinology","volume":"24 1","pages":"143 - 152"},"PeriodicalIF":1.4,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1297/cpe.24.143","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66287519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
