What Is the Exact Contribution of and Genes in Clubfoot Development? An Italian Study.

Congenital clubfoot is a common pediatric malformation that affects approximately 0.1% of all births. 80% of the cases appear isolated, while 20% can be secondary or associated with complex syndromes.

Deformity progression in congenital posteromedial bowing of the tibia: a report of 44 cases.

Background: congenital posteromedial bowing of tibia (CPMBT) is a very rare birth defect, characterized by shortened bowed leg and ankle deformity. We described a single institution experience in the management of CPMBT.

Methods: we identified 44 CPMBT in 44 children.

Neurofibromatosis type I and multiple myeloma coexistence: A possible link?

The association between Neurofibromatosis type I (NF1) and multiple myeloma (MM), a plasma cell, dyscrasia is very rare. Here we put to the attention of the scientific community two new cases. The first one is a patient with active MM whereas the second with smoldering MM.

Evolution of clubfoot deformity and muscle abnormality in the Ponseti method: evaluation with the Dimeglio score.

Purpose: The modality of progression of the correction along casting sessions of Ponseti method has been poorly investigated and information regarding evolution of muscular abnormalities is missing. The aim of the study was to investigate dynamics of correction of the different components of clubfoot deformity in a clinical setting.

Methods: In a prospective study, 124 clubfeet consecutively treated by a single orthopaedic surgeon were evaluated with the Dimeglio system at each casting session and score progression was determined.

New insights into osteogenic and chondrogenic differentiation of human bone marrow mesenchymal stem cells and their potential clinical applications for bone regeneration in pediatric orthopaedics.

Human mesenchymal stem cells (hMSCs) are pluripotent adult stem cells capable of being differentiated into osteoblasts, adipocytes, and chondrocytes. The osteogenic differentiation of hMSCs is regulated either by systemic hormones or by local growth factors able to induce specific intracellular signal pathways that modify the expression and activity of several transcription factors. Runt-related transcription factor 2 (Runx2) and Wnt signaling-related molecules are the major factors critically involved in the osteogenic differentiation process by hMSCs, and SRY-related high-mobility-group (HMG) box transcription factor 9 (SOX9) is involved in the chondrogenic one.
