Bone marrow aspirate has been shown to add stem cells, growth factors, and cytokines to bone graft matrices used in bone augmentation sites. The combination of bone marrow aspirate and resorbable scaffold material has a significant osteogenic capability that exceeds that of autogenous bone grafts. This article describes a subperiosteal tunneling technique for applying such grafts to defective sites. Treatment of 2 patients for whom the technique was used to graft 6 deficient sites is described. Histological results and histomorphometric analysis of bone core samples taken from 4 of the 6 grafting sites are also reported. Analysis of the 4 bone cores taken between 4 and 6 months showed a range of 34% to 45% of new bone.

Objective: Eosinophilic Otitis Media (EOM) is an intractable disease caused by type 2 inflammation, such as Eosinophilic Chronic Rhinosinusitis (ECRS) and bronchial asthma. Biologics have recently been used to treat ECRS and bronchial asthma. Biologics are not indicated for EOM; however, because approximately 10% of ECRS cases has concomitant EOM, concomitant EOM improvement has been observed when dupilumab is administered for ECRS.

Objectives: The pathogenesis of premature ovarian insufficiency (POI) not only affects the ovarian structure and function but also gives rise to complications such as osteoporosis and dyslipidemia. Although low-intensity pulsed ultrasound (LIPUS) has been proven effective in treating POI, its impact on the associated complications remains unexplored. Therefore, this study aims to investigate the effects of LIPUS irradiation on osteoporosis and dyslipidemia in a mouse model of POI.
View Article and Find Full Text PDFAims: ultrasound (US) diagnosis of enthesitis is burdened of low specificity, especially when it is performed in patients with psoriasis (PsO) but without clinical psoriatic arthritis (PsA), because of mechanical, dysmetabolic and age-related concurrent enthesopatic changes. We propose a novel US score to quantify the cortical-entheseal bone remodeling burden of several peripheral entheses, aiming to improve the specificity of US for PsA-related enthesitis, and to evaluate its diagnostic value in PsO patients with subsequent diagnosis of psoriatic arthritis (PsO/PsA).
Methods: clinical and US data of 119 consecutive patients with moderate/severe PsO and nonspecific musculoskeletal symptoms, were included in this retrospective study.

Introduction - Rheumatoid arthritis (RA) is a chronic immune-mediated inflammatory disease, which causes local and systemic bone damage. The main goal of this work was to analyze, how treatment intervention with Ab501 (certolizumab mice equivalent) prevents the disturbances on bone structure and mechanics induced by arthritis. Methods - Thirty DBA/1 collagen-induced arthritis (CIA) mice were randomly housed in experimental groups, as follows: arthritic untreated (N=9), preventive intervention (N=10) and treatment intervention (N=11).
