It has been recognized for over 20 years that there is an association between patterns of early growth and long-term risk of traditionally adult onset diseases such as type 2 diabetes. This has been observed both in human epidemiological studies and in animal models. This led to the concept of the developmental origins of health and disease that suggests that the environment to which an individual is exposed during critical periods of development, such as the in utero...

Background: ‘D’ was a 7 year old Caucasian female who presented with a history of adult-type body odour starting at age 3 years. At age 6y 9m her bone age was 7y 10m. She had had a sharp increase in her weight in the past 2 years and her PCP noticed pubic hair growth. Her very anxious single mother was convinced she had a serious illness that needed immediate intervention.Case presentation: At presentation, D had Tanner 2 pubic hair and Tanner ...

Background: Turner syndrome (TS) is one of the most common genetic disorders in females and occurs in phenotypic females who are missing all or part of one sex chromosome. While the most common mosaic forms of the disorder are 45,X/46,XX and 45,X/46,Xiq, mosaicism for cells containing Y chromosome material is well documented.Objective and hypotheses: Owing to increased risk of gonadoblastoma (GB), current recommendations are for elective gonadectomy foll...

Background: Secondary pseudohypoaldosteronism (PHA) type 1 is an uncommon salt losing condition of infancy caused by transient resistance of the mineralocorticoid receptors (MR) of the renal tubule to aldosterone. This can be secondary to urinary tract infection (UTI), urinary tract malformation (UTM) or obstructive uropathy. Ninety percent of reported cases present before 3 months and nearly all are under 7 months of age.Objective and hypotheses: The co...

Background: Pancreatic epithelial cells represent an attractive cell source for replacement therapy of type 1 diabetes. Previously, we designed a protocol for expansion of human pancreatic duct-derived cells (HDDCs) and showed their β-cell engineering potential.Objective and hypotheses: In this study, we reprogrammed HDDCs into β-cell-like lineage by over-expressing mRNAs of key pancreatic transcription factors (TFs).Meth...

Background: Short stature is a recognized complication of Crohn’s disease (CD) in children. Less is known on the impact of disease on final adult height and body proportions.Objective and hypotheses: To assess height and body proportions in 48 adults (F: 30; M: 18) with childhood (ACO) or adult (AAO) onset CD and 44 children (C) (F:22; M:22) with CD.Method: Standing, sitting height (SH) and leg length (SILL) were measured and ...

Background: PHP is a rare heterogeneous genetic disorder causing parathyroid hormone (PTH) resistance. This condition is caused by deficiency of the α subunit of the protein Gs, encoded by GNAS gene. Clinical classification is based on presence or absence of Albright hereditary osteodystrophy (AHO) and multiple or single hormone resistance, to PHP1a/1c and PHP1b respectively.Objective: To describe the clinical and practical management of a case of P...

Background: The association between Turner syndrome and Type1/ Type 2 diabetes is well known. Growth hormone is also utilized in Turner syndrome to improve height outcomes, but association of Turner patients with growth hormone deficiency is rare. To my knowledge, there are no cases of concurring Turner syndrome, Type 1 diabetes, and growth hormone deficiency.Objectives: To describe a rare case where a child diagnosed wi...

Background: Obesity is a persistent disorder that almost universally recurs following treatment, suggesting a disruption on central nervous system control over energy homeostasis. Recent literature suggests that hypothalamic inflammation may have an important role on obesity pathogenesis. This inflammatory reaction, which histologically appears as a reactive gliosis, may be detected using magnetic resonance imaging (MRI), and has just been shown in rodent models and adults.</p...

Introduction: There are few longitudinal male cohort studies with serial assessments of growth and puberty.Objective: To describe the design and implementation of a longitudinal cohort study of Russian boys evaluated annually for growth, development and puberty.Design/methods: We assembled a multi-disciplinary team of U.S. and Russian researchers to design and conduct a longitudinal boys’ cohort study in Chapaevsk, Russia with...
