ABSTRACT Objective: The aim of this study was to characterize the parameters of reproductive anatomy and pituitary hormone expression levels in ames dwarf mice (Prop1df/df). Materials and methods: Male Prop1df/df mice aged 30 days received daily intraperitoneal injections of recombinant human GH and levothyroxine three times weekly for 60 days. The sexual maturation of these animals was compared with that of their wild-type (Prop+/+) and untreated (Prop1df/df) siblings. Results: The Prop1df/df treated group developed sexual maturation 2 weeks later than […]

INTRODUCTION: Neonatal cholestasis due to endocrine diseases is infrequent and poorly reco-gnized. Referral to the pediatric endocrinologist is delayed. OBJECTIVE: We characterized cholestasis in infants with congenital pituitary hormone deficiencies (CPHD), and its resolution after hormone replacement therapy (HRT). SUBJECTS AND METHODS: Sixteen patients (12 males) were included; eleven with CPHD, and five with isolated central hypocortisolism. RESULTS: Onset of cholestasis occurred at a median age of 18 days of life (range 2-120). Ten and nine patients had elevated transaminases […]
