Methods: In this article, the authors review the most common reconstructive strategies for all types of traumatic thumb defects. Results: Replantation is approached first as the primary option for most amputations. Nonreplantable injuries are organized using a simple classification adapted from Lister, dividing thumb amputations into four functional categories:

soft-tissue deficit with acceptable length, subtotal amputation with borderline length, total amputation with preservation of the carpometacarpal joint, and total amputation with destruction of the carpometacarpal JAK/STAT inhibitor joint. Within each category, relevant microsurgical and nonmicrosurgical reconstructive techniques are discussed, with a focus on appropriate technique selection for a given patient. Evidence and outcomes data are reviewed where available, and

case examples from our own experience are provided. Conclusions: Given that available options now range from simple gauze dressings to complex microsurgical reconstruction, preservation of reconstructive flexibility is essential and should be facilitated by judicious preservation of intact structures. The divergence of available reconstructive pathways underscores the importance of knowing one’s patients, understanding their motivation, and assessing their Selleck PXD101 goals. Only in properly matching the right reconstruction with the right patient will a mutually satisfactory result be achieved.”
“Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) play key roles in tumorigenesis, but little is known of their expression according to mucinous or serous type. This study aimed to evaluate the immunohistochemical expression of MMP-2. -7, -9. MT1-MMP, TIMP-1 and -2 in these tumors. A Staurosporine research buy tissue microarray was set up including 99 serous (25 benign, 27 borderline, 47 malignant) and 79 mucinous (25 benign, 44 borderline, 10 malignant) ovarian tumors. Immunostaining results were scored by using the HSCORE and assessed by univariate, unsupervised hierarchical clustering and multidimensional scaling analyses. Epithelial expression

of MMP-2, -7, -9, MT1-MMP, TIMP-2. but not TIMP-1, was higher in serous than mucinous tumors. Stromal expression of MMP-7 was higher in serous tumors. Alterations in MT1-MMP, MMP-7 and -9 were found in malignant serous tumors, while benign and borderline tumors shared similar expressions. By unsupervised hierarchical clustering analysis, mucinous and serous tumors were better differentiated by epithelial than stromal MMP and TIMP immunolabelling. By multidimensional scaling analysis, the expressions of MMPs and TIMPs were scattered in serous tumors and homogeneous for mucinous tumors. In conclusion. our results support the differential expression in MMPs and TIMPs of ovarian tumors according to serous or mucinous histology.”
