ABSTRACT
Mucous membrane pemphigoid (MMP) is an autoimmune blistering, scarring and occasionally mutilating disease that may progress to blindness or airway obstruction. Over the past few years, rituximab (RTX) has emerged as a potential therapeutic solution for MMP; however, the literature regarding its efficacy in the treatment of severe MMP is sparse. We studied four patients with recalcitrant MMP who were treated with RTX. Three of these had recalcitrant laryngeal disease; two were unresponsive to RTX, while the third patient achieved complete remission (CR) but relapsed twice. The fourth patient, who had oral and ocular disease, also achieved CR. In addition, we reviewed 143 cases of MMP treated with RTX reported in the literature to date. Of these, 120 had late observation endpoints, of whom 81 (67.5%) achieved CR, 24 (20%) received partial remission and 15 (12.5%) had no remission. Based on this study, the presence of laryngeal MMP seems to predict refractoriness to RTX treatment. In conclusion, we found that RTX can ameliorate the MMP course and that laryngeal involvement, which is known to be a prognostic factor for severe MMP, may also predict poor response to RTX.

UNLABELLED: Nutritional approaches may help to preserve bone quality. The purpose of our study was to demonstrate the efficiency of an innovative bone health product (BHP) including micellar casein rich in calcium, vitamin D2 and vitamin K2, to improve bone mineral density. INTRODUCTION: The aim of postmenopausal osteoporosis treatment is to decrease bone resorption and/or increase bone formation. Because of the slow bone turnover, osteoporosis prevention and therapies are long-lasting, implying great costs and poor compliance. Even if the effects of nutrition on bone are not as marked as that of pharmaceutical agents, it can be of great help. The purpose of our study was to demonstrate the efficiency of an innovative bone health product (BHP) containing micellar casein rich in calcium, vitamin D2 and vitamin K2, for the improvement of bone mineral density (BMD). METHODS: An ovariectomized mice model was used to study the effect of different concentrations of the ingredient on BMD and microarchitectural parameters. Blood concentrations of C-terminal telopeptide of type I collagen (CTX), N-terminal propeptide of type 1 procollagene (PINP), alkaline phosphatase (ALP), osteocalcin (OC) and RANKL were also measured to evaluate bone remodelling, To evaluate the efficiency of the product to modulate osteoblast and osteoclast growth and differentiation, primary murine bone cells were used. RESULTS: In vivo studies showed that BMD and microarchitectural parameters were dose-dependently improved after ingestion of the supplement for 3 months. We also report increased osteoblast activity as shown by increased OC activity and decreased osteoclastogenesis as shown by reduced CTX activity. In vitro studies support that BHPs stimulate osteoblast differentiation and mineralization and inhibit osteoclast resorption activity. CONCLUSION: Our results show that, when chronically ingested, BHPs improve BMD of ovariectomized mice. This work supports that providing an ingredient including micellar casein rich in calcium, vitamin D2 and vitamin K2 is more efficient than the control diet to maintain bone quality.

OBJECTIVE: To assess self-reported stress during the performance of different procedures in pediatric dentistry, according to the professional experience of the dentists. STUDY DESIGN: During the years 2010 to 2011, an anonymous survey was administered by means of an internet link, and by distribution at professional meetings of dentists . RESULTS: No statistically significant differences in stress were reported for maxilla and mandibular procedures. Placement of a rubber dam was rated as the most stressful procedure among dental students. For general practitioners and specialists, injection of local anesthesia to an anxious child was the most stressful procedure, regardless of age, sex, or years of professional experience. A negative correlation was found between years of experience and level of stress for all the procedures surveyed, but not for the use of nitrous oxide. No differences were found between male and female dentists in stress scores for any of the procedures. CONCLUSION: Higher rates of stress during operative procedures were reported among dental students than among experienced dentists. Anxiety of the pediatric patients, but not the location of the procedure: maxillary or mandibular, affected the dentists' reported level of stress.
