Objectives: To estimate the status of 25-hydroxyvitamin D in healthy Mexican children and to describe factors related to vitamin D deficiency.Methods: A cross-sectional study was conducted in children 2–14 years old in Mexico City and Toluca Edo de Mexico. Trained interviewers applied a questionnaire including all relevant demographics, medical history, sun exposure, sunblock use and skin phototype. Morning fasting blood was collected in all subject...

Background: Osteoporosis in otherwise healthy children demands thorough study as it may be the first manifestation of an occult illness. When other diseases can be ruled out, juvenile idiopathic osteoporosis (JIO) is the purported diagnosis.PresentationWe report the case of an 8-year -old boy with no personal or family history of chronic disease who presented with sudden ankle pain unrelated to trauma and not responsive to rest and...

Background: Vitamin D (Vit-D) plays a role in calcium metabolism during pregnancy, and studies have found widespread deficiency in this period. Its significance is still not fully understood, although low Vit-D levels have been associated with increased risk for preeclampsia, bacterial vaginosis, neonatal sepsis and early respiratory infections in the infant. Supplementation to the pregnant mother remains a matter of debate; thus, it is important to better understand the cause...

Rationale: Trabecular Bone Score (TBS) is a texture-based tool analyzing DXA images in order to assess bone microarchitecture in the lumbar region. In pediatric population, definition of normative values has remained elusive due to the disparities of results in normal population, probably link to uncontrolled factors which impact bone microarchitecture and the nonlinear behavior of bone growth. Our objective was to evaluate TBS in healthy Mexican children and adolescents using...

Chronic kidney disease in children causes multiple bone alterations, particularly renal osteodystrophy, which affects both bone quality and size, in turn causing short stature, bone deformities and brittleness. Once they get a transplant, this process starts to revert, and although mineral alterations improve, short stature often requires growth hormone supplementation but bone fragility requires evaluations in order to revert the disease’s effects. DXA is a valuable tool...

Fracture prevalence in children appears to change in recent years due to variations in physical activity and enforcement of laws that protect children within motor vehicles. However, in Mexico such variation has not been explored so far.Objective: To analyze fracture prevalence in the paediatric population of Mexico to detect patterns of change in time, between genres and among different diagnoses.Methods: We analyzed data from the...
