There has been a global increase in pediatric endocrinology referrals for the concerns of early puberty. The objective of this study was to determine the reasons behind this increase. A retrospective cross-sectional study was designed to analyze the clinical characteristics of patients seen for the concerns of early puberty in pediatric endocrinology clinic of a tertiary care center (Study A). Additionally, a prospective questionnaire study was designed to assess the knowledge and concerns of the mothers regarding the timing of puberty in girls (Study B). In study A, of the 305 girls, 42.9% were overweight/obese, 68.5% either had normal pubertal development for age or were prepubertal, 1 had non-classic congenital adrenal hyperplasia, and 2 had central precocious puberty. Of the 36 boys, 56% were overweight/obese, 64% either had normal pubertal development for age or were prepubertal, and 1 had non-classic congenital adrenal hyperplasia. In study B, 95% of the participants thought the girls have been developing earlier, over 10% considered the first sign of puberty to be normal after the age 14 years and 12.4% considered menarche to be normal after age 14 years. The common sources of anxiety for the participants regarding the earlier timing of puberty were psychosocial issues and short final height. In conclusion, many parents had wrong beliefs/information about the normal timing of puberty and were concerned about precocious puberty in girls. Education of parents about the normal timing of puberty may help avoiding unnecessary referrals, parental anxiety, and financial burden to the society.
Persistent Hyperinsulinemic Hypoglycemia with Pancreatic Teratoma in Infancy: A Case Report
(2020) Cemeroglu, Ayse Pinar; Sarialioglu, Faik; Belen-Apak, Fatma Burcu; Terzi, Yunus Kasim; 0000-0002-8257-810X; 32782239; AAL-7766-2021
Objective: Unusual clinical course Background: Pediatric intraabdominal pancreatic teratomas have been rarely reported. This is the first case of severe hyper-insulinemic hypoglycemia in a 6-month-old infant secondary to an intraabdominal teratoma. The hypoglycemia resolved after surgical removal. Case Rreport: A 6-month-old infant was seen in a pediatric emergency department with complaints of lethargy and abnormal eye movements. She was diagnosed with hyperinsulinemic hypoglycemia and started on diazoxide. A CT and MRI of the abdomen revealed a 165x77x72 mm cyst with a 51x45x30 mm solid structure connecting to the wall of the cyst by a stalk, raising suspicion of a fetus in fetu. The mass had no connection to her pancreas. Following total excision of the intraabdominal mass, her hypoglycemia resolved. Histopathological examination showed immature fetal pancreatic tissue consistent with a mature teratoma. Whole exon sequencing of the infant's peripheral blood showed a negative mutation of ABCC8 and presence of heterozygous variations of HNF1b and IRS1 genes. Conclusions: This is the first case report of an infant with severe hyperinsulinemic hypoglycemia secondary to a pancreatic teratoma. The heterozygous variations of HNF1b and IRS1 genes likely played a role in the embryogenesis, causing a pancreatic teratoma and hyperinsulinemic hypoglycemia.
