Telomere length is not altered in girls with idiopathic central precocious puberty treated with a GnRH analog - leuprolide acetate.

Background: Idiopathic central precocious puberty (iCPP) presents a disproportionate advancement of bone age and maturation, as well as metabolic and endocrinological changes that may be related to effects on telomere biology.

Objective: To investigate the telomere length in iCPP girls treated with GnRHa.

Study Design: Observational case-control study with 85 girls, including 45 iCPP treated with GnRHa and 40 controls.

Use of a Gonadotropin-releasing Hormone Analog to Treat Idiopathic Central Precocious Puberty Is Not Associated with Changes in Bone Structure in Postmenarchal Adolescents.

Study Objectives: To evaluate bone quantity and quality in postmenarchal adolescents treated for idiopathic central precocious puberty (CPP) in childhood with a gonadotropin-releasing hormone analog (GnRHa) and to determine the serum concentrations of bone remodeling markers.

Design And Participants: This cross-sectional study included 53 postmenarchal adolescent girls who were divided into 2 groups: 27 adolescents who were treated with GnRHa in childhood for idiopathic CPP (the CPP group) and 26 women who presented with physiological development of secondary sex traits (the control group).

Interventions: None.

Analysis of bone microarchitecture related to anthropometry in climateric women.

Background: Osteoporosis is one of the most important public health problems involving a high percentage of costs in the medical care system. Reliable diagnostic techniques for an early detection of bone deterioration and studies of factors that influence its development in menopausal women are crucial. The aim of the study was to determine the relationship between bone microarchitecture and anthropometry in climacteric women.
