[Domestic exposure to moulds and mite allergens in Parisian patients].

Introduction: Moulds and mite allergens present in indoor environments are well known for their effects on respiratory health.

Methods: From 2011 to 2015, the Paris Service for Environmental Health (SPSE) conducted investigations in 293 dwellings following medical referral. These audits included fungal analysis of air (in 12% of dwellings), in mattress surface and floor dust (24%), and mite allergen quantifications in mattresses and carpets (18%).

Effects of autologous platelet rich plasma gel and calcium phosphate biomaterials on bone healing in an ulnar ostectomy model in dogs.

The aim of the study was to evaluate the bone healing properties of an osteopromotive platelet rich plasma (PRP) gel in combination with osteoconductive calcium phosphate (CaP) ceramic granules in a long-bone critical size defect in dogs. A standardised 2 cm long ulnar ostectomy was performed bilaterally in four dogs to compare new-bone formation by CaP matrix with and without association with PRP. Radiographic and histological evaluations were performed blindly.
