Objectives: Differential diagnosis vs. Osteogenesis Imperfecta (OI).Methods: The parents were Moroccan origin, consanguineous. The patient is an 8 year old girl, who was visited for a first time in our hospital in October 2016, presenting a fracture of the left femur, with dramatic bone deformations, with important disability, unable to walk and with growth retardation (weight 15 kg, length: 92 cm). The first registered fracture is at birth, consisting o...

Objectives: Neurofibromatosis 1 (NF1) is one of the most common autosomal dominant diseases. Skeletal involvement such as short stature, kyphoscoliosis, tibial bowing and pseudarthrosis are common osseous manifestations of NF1. Moreover, there is a growing evidence that reduced bone mineral density (BMD), is a common feature of NF1 subjects. The aim of the study was to evaluate the usefulness of Bone Mineral Density and Quantitative Ultrasound (QUS) at phalanxes in the assessm...

Background and aim: Multifaceted risk factors impair bone mass in childhood cancer survivors. Aims of the study were to evaluate bone mass and it’s determinant and fracture prevalence in CBCS 2 (G+2) or 5 (G+5) years after off therapy (OT).Methods: Seventy-three (G+2) and 87 (G+5) CBCS were evaluated at 12.9±4.2 and 14.9±4.4 yrs, respectively. Diagnoses were: astrocytic (G+2:n=25, G+5:n=24), embryonal (G+2:n=28, ...

McCune-Albright-Syndrome (MAS) is a rare multisystem disorder presenting with polyostotic fibrous dysplasia accompanied by a list of extraskeletal features including café-aulait spots and various endocrine hyperfunctioning. There is no effective treatment for FD in MAS nowadays. Patients with MAS (n=60, 49 girls(G) and 11 boys (B) have been diagnosed and followed up during 20 years in the Institute of Pediatric Endocrinology. First clinical manifestations were pe...

Objective: Existing case series examining outcomes following spine surgery for patients with skeletal dysplasias demonstrate high rates of complications. Yet, these earlier studies are from a single institution, contain surgeries performed almost 50 years ago, and only include patients with a diagnosis of achondroplasia. The objective is to determine contemporary outcomes after spinal surgery in patients with skeletal dypslasias, focusing on complications and revisions. We pre...

Osteogenesis imperfecta is a disorder characterized by bone fragility. Current management includes the usage of bisphosphonates to improve bone stock and manage pain. Outcomes in adults have mainly been reported in terms of presentation compared to genotype, most probably due to the heterogeneity of the disease. The head and neck resection of the femur, or Girdlestone procedure, was a common procedure to treat infections of the hip but it has fallen out of favor due to the adv...

Introduction: Epithelioid hemangioendothelioma (HEE) is a tumor of vascular origin, infrequent in the pediatric age and even more infrequent at intestinal level. To our knowledge, there are no previous reports of pediatric patients with malignant humoral hypercalcemia associated with this tumor. Humoral mechanism is seen more often in lung, uterine cérvix, skin and esophagus tumors. The presence of hypercalcemia appears to be an ominous prognostic sign.<p class="abste...

Objective: Bone and muscle deficits are observed in patients with Crohn’s disease (CD). High-impact exercise (HIE), such as jumping based exercise, can provide hypertrophic and osteogenic stimulus, however to date there have been no studies of HIE in CD. This study aimed to assess the acceptability and feasibility of participating in HIE in adolescents and adults with CD.Methods: Two anonymous questionnaires surveyed adolescents and adults, respecti...

Introduction: Osteoporosis is frequently associated with renal disease, namely the bone metabolism disturbances caused by secondary hyperparathyroidism of chronic kidney disease (CKD). The increased risk of fragility fractures is well demonstrated in patients with end-stage renal disease (ESRD). There is recent evidence that bone pathological changes start early in the course of CKD. Our aim is to evaluate whether chronic renal disease, before ESRD, is associated with bone fra...

In order to examine metabolic and biophysical parameters arising from obesity, male rats were given to drinking 30% sucrose (p/v) for 8 weeks. During the experimental period, animals in the control group (C) consumed higher amounts of food and water, but the body mass was smaller than the group receiving sucrose (S). In this group, the caloric load given to the animals for eight weeks resulted in increased energy consumption, in glycemia and in plasma leptin and abdominal fat....
