    Background. Chronic graft versus host disease (cGVHD) is a complication following bone marrow transplantation. The oral lesions are difficult to control with a systemic pharmacological therapy. Case Description. A 63-year-old female patient, who underwent an allogeniec transplantation for acute myeloid leukemia, developed a chronic oral and cutaneous GVHD. The patient was treated with topical tacrolimus 0.1%, twice daily for two months, and underwent a protocol of oral hygiene characterized by 3 appointments of scaling, root planning, and daily oral hygiene instructions. The patient showed marked resolution of gingival lesions and a significant improvement of related pain and gingival inflammatory indexes. Clinical Implications. This case report suggests that treatment with topical tacrolimus and professional oral hygiene may be helpful in the management of chronic oral GVHD with severe gingival involvement

    Background: Oral lichen planus (OLP) is a chronic inflammatory disease, affecting nearly 1-2% of the population; Proposed therapies are usually symptomatic and numerous drugs have been used, but recently, it has been published that there is insufficient evidence to support the effectiveness of any specific treatment as being superior. To the best of our knowledge, direct evaluation of the efficacy of topically applied pimecrolimus and tacrolimus in the treatment of atrophic-erosive OLP, refractory to topical steroids, is still lacking. Objectives: To assess the efficacy and safety of topical calcineurin inhibitors for unresponsive OLP. An 8 week randomized, double-blind controlled trial, followed by a 6 month follow-up period. Patients were treated with either pimecrolimus 1% cream or tacrolimus 0.1% ointment, both mixed with an equivalent amount of 4% hydroxyethyl cellulose gel. The medications were to be applied twice daily for 2 months. Each patient was examined at the beginning of therapy, and then every 2 weeks during the treatment and every 3 months of follow-up. Main outcome measures were: (i) to compare the effectiveness of topically applied pimecrolimus and tacrolimus; (ii) to evaluate which is more cost-effective; (iii) to determine which drug is faster in reducing signs and symptoms and (iv) which gives the longest remission. Results: Thirty patients were involved in the study. Both drugs were effective at inducing clinical improvement, with no statistical difference. Pimecrolimus creams revealed a significantly better stability of the therapeutic effectiveness (P = 0.031). Conclusion: Both medications would currently appear to be a treatment of choice for patients with unresponsive atrophic-erosive OLP. Pimecrolimus seemed to be more effective in providing long-term resolution of signs and symptoms. Future efforts are however needed to obtain more objective evidence of the benefit of these medications in the treatment of immunologically mediated oral mucosal lesion. © 2013 European Academy of Dermatology and Venereology

    Stratifying prognosis following coronary bifurcation percutaneous coronary intervention (PCI) is an unmet clinical need that may be fulfilled through the adoption of machine learning (ML) algorithms to refine outcome predictions. We sought to develop an ML-based risk stratification model built on clinical, anatomical, and procedural features to predict all-cause mortality following contemporary bifurcation PCI. Multiple ML models to predict all-cause mortality were tested on a cohort of 2393 patients (training, n = 1795; internal validation, n = 598) undergoing bifurcation PCI with contemporary stents from the real-world RAIN registry. Twenty-five commonly available patient-/lesion-related features were selected to train ML models. The best model was validated in an external cohort of 1701 patients undergoing bifurcation PCI from the DUTCH PEERS and BIO-RESORT trial cohorts. At ROC curves, the AUC for the prediction of 2-year mortality was 0.79 (0.74–0.83) in the overall population, 0.74 (0.62–0.85) at internal validation and 0.71 (0.62–0.79) at external validation. Performance at risk ranking analysis, k-center cross-validation, and continual learning confirmed the generalizability of the models, also available as an online interface. The RAIN-ML prediction model represents the first tool combining clinical, anatomical, and procedural features to predict all-cause mortality among patients undergoing contemporary bifurcation PCI with reliable performance
