Background: The baby growing in its mother’s womb needs calcium for skeletal development. Maternal osteoporosis has been attributed to pregnancy in some cases.Presenting problem: A 27-year-old woman in the 7th month of her first pregnancy complained of mid-thoracic back pain after lifting a non-heavy object. The pain remained with differing intensity and was attributed to her pregnancy. After the delivery of a healthy child, the back pain prevented ...

Objectives: Adolescent idiopathic scoliosis (AIS) is a complex three-dimensional spinal deformity associated with low bone mass. Our previous clinical trial demonstrated the anabolic bone effect of vibration treatment (VT) at the femoral neck in AIS subjects. The therapeutic effect was more pronounced in those with optimal serum 25(OH) Vit-D level (>40 nmol/l). To investigate possible factor interaction between Vit-D and VT on their anabolic bone effects, this in-vitro...

Introduction: The availability of bone turnover markers (BTMs) that are kidney independent has facilitated the monitoring of bone turnover in renal patients with hyperparathyroid bone disease. The effects of Cinacalcet on BTMs and on the relationship between parathyroid hormone (PTH) and BTMs were studied.Methods: The formation marker procollagen type 1 N propeptide (P1NP) and resorption marker tartrate resistant acid phosphatase 5b (TRACP5b) were measur...

Background: In this case report, we introduce a patient presenting a potentially unknown syndrome with skeletal involvement.Presenting problem: At the time of physical examination, the boy was 10 years old, displaying short stature (z-score=−4.4), hearing loss, visual impairment, delayed eruption of teeth and severe dental caries, dysmorphic facial features, micrognathia, mild platyspondyly and genu valgum. Although he appears to have normal intell...

The childhood obesity is a global epidemic. Some studies with pre-pubertal children reported a positive relationship between fat mass and bone. However, there are no available data on the influence of the nutritional status on parameters of quantitative ultrasound (QUS). The aim of this study was to evaluate the influence of nutritional status in bone mass assessed by QUS of proximal phalanges in girls. The bone mass parameter, amplitude dependent speed sound (AD-SoS) in meter...

Background: Congenital tibial pseudarthrosis (CTP) presents with anterolateral bowing of the lower leg in infancy, which often progresses to fracture and non-union (pseudarthrosis). CTP occurs in 2–3% of children with NF1. The distal end of the fibula and other long bones can also be affected.Objective: We describe three children in whom NF1 related congenital tibial or fibular pseudarthrosis was initially misdiagnosed as NAI....

The objective of this study was to analyze measurement properties of BeamMed Omnisense quantitative ultrasound (QUS) of the radial and tibial speed of sound (SoS) for assessing bone health and screening bone fragility in youth. Bone fragility was defined as low whole body less head bone mineral density (WBLH BMD) measured by DXA (first tertile, 95% CI: −1.1– (−0.9)) and as past history of fractures evaluated by questionnaire. The study was conducted with 319 n...

miRNAs are epigenetic regulators of gene expression, increasingly recognised as prominent regulators of bone metabolism. Following our in vitro studies of miRNAs profiles in osteoblasts we extended the research to human bone samples. Our aim was to find and functionally validate miRNAs differentially expressed in osteoporotic and osteoarthrotic bone with potential for targeting genes relevant in bone metabolism.Trabecular bone tissue samples wer...

Objective: Evaluate the clinical characteristics of all Latin American pediatric patients with Gaucher disease type 1 (GD1) enrolled in the ICGG Gaucher Registry at baseline and investigate long-term outcomes and clinical benefit of prolonged imiglucerase/alglucerase therapy in patients with manifestations of GD1 at baseline.Methods: All Latin American patients with GD1 in the ICGG Gaucher Registry (NCT00358943) who were <18 years of age at the start...
