Background A persistent problem in autologous breast reconstruction in skin-sparing mastectomies is skin restoration after skin necrosis or secondary oncological resection. As a solution to facilitate reconstruction, skin banking of free-flap skin has been proposed in cases where the overlying skin envelope must be resected, as this technique spares the patient an additional donor site. Herein, we present the largest series to date in which this method was used. We investigated its safety and the possibility of skin banking for prolonged periods of time. Methods All skin-sparing mastectomies and immediate autologous breast reconstructions from December 2009 until June 2013 at our institution were analysed. Results We identified 31 patients who underwent 33 free flap reconstructions in which skin banking was performed. Our median skin banking period was 7 days, with a maximum duration of 171 days. In 22.5% of cases, the banked skin was used to reconstruct overlying skin defects, and in 9.6% of cases to reconstruct the nipple-areolar complex. Microbiological and histological investigations of the banked skin revealed neither clinical infections nor malignancies. Conclusions In situ skin banking, even for prolonged periods of time, is a safe and cost-effective method to ensure that skin defects due to necrosis or secondary oncological resection can be easily reconstructed.

Ternary organic photovoltaic devices were prepared through the addition of small amounts of metalloporphyin-terthiophenes to two established low bandgap polymer:fullerene blends. The methodology afforded a PCDTBT:PC<SUB>71</SUB>BM-based device that displayed an initial power conversion efficiency of 5.1%, an increase of 16% when compared to the binary blend. Among the range of metalloporphyrins considered in this study, the Cu(II)-porphyrin derivatives were found to result in the most significant efficiency improvements.

Background Pectus excavatum is less common in females than in males, and it often aggravates a coexistent breast asymmetry. We conducted a study comparing female patients' versus medical professionals' evaluation of pectus excavatum repair to assess differences in aesthetic outcome ratings. Moreover, we evaluated the influence of surgical correction on patients' self-perception. Methods Of 30 female patients who were initially screened, 18 patients (mean age, 20 years) who underwent bar removal after surgical correction of pectus excavatum deformity participated in the survey (60%). They completed a questionnaire rating their appearance before and after surgery and responded to a psychological questionnaire about the changes that they had experienced. The mean interval between pectus bar removal and evaluation was 28 months. Standardized preoperative and postoperative patient photographs were evaluated using the same questionnaire by a panel of medical professionals and students (n=24) and the results were compared. Results Patients rated their preoperative deformity as more severe than the other evaluators, revealing the significant impact of the deformity on patients' self-perception. Postoperatively, patient and professional evaluations were much better than before and were very similar. The psychological evaluation showed a clear improvement in well-being. The ratings of the medical professionals were not influenced by their degree of medical education. Conclusions Surgical correction of pectus excavatum in female patients positively influences body perception and psychological well-being. It should therefore not be considered as a merely aesthetic correction, but as an important procedure to restore a patient's self-perception.
