The aim of our analysis was to explore the effects of immunosuppression on the rates of wound complications. Comparative analysis of immunocompetent and immunocompromised patients with elective mesh repair of inguinal, femoral, primary ventral, incisional or parastomal hernia between January 2001 and December 2013. Immunosuppression included glucocorticoids, biologicals, chemotherapy and chemoradiotherapy. Primary outcome parameter was mesh infection rate. Follow-up questionnaires were completed in written form or by telephone interview. Questionnaire response rate was 59.5% (n = 194) with a median follow-up of 33 (interquartile range 28-41) months. There were no differences between immunocompromised (n = 40, 20.6%) and immunocompetent patients (n = 154, 79.4%) based on hernia and patient characteristics. Immunosuppression was not associated with the rates of mesh infecth. However, immunosuppression and mesh infection are risk factors for hernia recurrence. Electronic cigarettes have given rise to a new, largely unregulated market within the smoking industry. While generally supposed to be less harmful than traditional tobacco smoke, awareness of the biological effects of electronic cigarette liquid is still scarce. Our objective was to determine the impact of electronic cigarette flavoring and nicotine on gingival squamous cell carcinoma invasion, RAGE expression, and the elaboration of pro-inflammatory molecules. Gingival and tongue squamous cell carcinoma cells were exposed to Red Hot or Green Apple flavored electronic cigarette flavoring with or without nicotine. Immunofluorescence determined RAGE expression. Real-time cellular invasion was assessed using a RTCA DP instrument. Culture medium was assayed for cytokine secretion. Compared to controls we observed increased cel
