Contributions by Martin Grotschel's doctoral descendants. 330 $aMartin Grötschel is one of the most influential mathematicians of our time. He has received numerous honors and holds a number of key positions in the international mathematical community. He celebrated his 65th birthday on September 10, 2013. Martin Grötschel?s doctoral descendant tree 1983?2012, i.e., the first 30 years, features 39 children, 74 grandchildren, 24 great-grandchildren, and 2 great-great-grandchildren, a total of 139 doctoral descendants.  This book starts with a personal tribute to Martin Grötschel by the editors (Part I), a contribution by his very special ?predecessor? Manfred Padberg on ?Facets and Rank of Integer Polyhedra? (Part II), and the doctoral descendant tree 1983?2012 (Part III). The core of this book (Part IV) contains 16 contributions, each of which is coauthored by at least one doctoral descendant.  The sequence of the articles starts with contributions to the theory of mathematical optimization, including polyhedral combinatorics, extended formulations, mixed-integer convex optimization, superclasses of perfect graphs, efficient algorithms for subtree-telecenters, junctions in acyclic graphs, and preemptive restricted strip covering, as well as efficient approximation of non-preemptive restricted strip covering.  Combinations of new theoretical insights with algorithms and experiments deal with network design problems, combinatorial optimization problems with submodular objective functions, and more general mixed-integer nonlinear optimization problems. Applications include VLSI layout design, systems biology, wireless network design, mean-risk optimization, and gas network optimization.  Computational studies include a semidefinite branch and cut approach for the max k-cut problem, mixed-integer nonlinear optimal control, and mixed-integer linear optimization for scheduling and routing of fly-in safari planes.  The two closing articles are devoted to computational advances in general mixed-integer linear optimization, the first by scientists working in industry, the second by scientists working in academia. These articles reflect the ?scientific facets? of Martin Grötschel who has set standards in theory, computation, and applications. 606 $aCombinatorial optimization 615 0$aCombinatorial optimization. 676 $a003.3 676 $a519.6 676 $a519.64 701 $aJu?nger$b M$g(Michael)$00 701 $aReinelt$b G$g(Gerhard)$01220838 701 $aGro?tschel$b Martin$042045 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910438027203321 996 $aFacets of combinatorial optimization$94202255 997 $aUNINA LEADER 06316nam 22007695 450 001 9910568257403321 005 20260202154228.0 010 $a3-030-76670-5 024 7 $a10.1007/978-3-030-76670-2 035 $a(MiAaPQ)EBC6976408 035 $a(Au-PeEL)EBL6976408 035 $a(CKB)21989073400041 035 $a(PPN)269155058 035 $a(OCoLC)1315652625 035 $a(DE-He213)978-3-030-76670-2 035 $a(EXLCZ)9921989073400041 100 $a20220504d2022 u| 0 101 0 $aeng 135 $aurcnu|||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aAnal Fistula and Abscess /$fedited by Carlo Ratto, Angelo Parello, Francesco Litta, Veronica De Simone, Paola Campennì 205 $a1st ed. 2022. 210 1$aCham :$cSpringer International Publishing :$cImprint: Springer,$d2022. 215 $a1 online resource (698 pages) 225 1 $aColoproctology,$x2511-8161 311 08$aPrint version: Ratto, Carlo Anal Fistula and Abscess Cham : Springer International Publishing AG,c2022 9783030766696 320 $aIncludes bibliographical references and index. 327 $aAnorectal Anatomy Related to Anal Fistula and Abscess -- Anorectal Physiology Related to Anal Fistula and Abscess -- Classification of Anal Fistula and Abscess: Useful Features to Address the Treatment -- Epidemiology of Anal Fistula and Abscess -- From Abscess to Fistula: Is This the Rule? -- Pathophysiology of Anal Fistula and Abscess: Old Concepts and New Insights -- Severity Scores for Anal Fistulas -- Unconventional insights into etiology of fistulas in the peri-anal region -- Clinical Assessment of Crohn?s Anal Abscess and Fistula -- Clinical Assessment of Cryptoglandular Anal Abscess and Fistula -- Anorectal Physiology Assessment in Patients With Anal Fistula: When Necessary? -- Endoanal Ultrasound in The Diagnosis of Cryptoglandular Anal Fistula and Abscess -- Future perspectives in The Diagnosis of Anal Fistula and Abscess -- Magnetic Resonance and Traditional Radiology in The Diagnosis of Cryptoglandular Anal Fistula and Abscess -- Magnetic Resonance in The Diagnosis of Crohn?s Anal Fistula and Abscess -- Utility and Limitations of Endoanal Ultrasound in The Diagnosis of Crohn?s Anal Fistula and Abscess -- Additional Surgical Options to Treat Anal Fistulas: Gracilis Interposition, Martius Flap, Gluteal Flap -- Anal Fistula: Actual Perspectives of Scientific Research Toward the Future -- Correct Use of Setons: Is There Any Agreement? -- Dermal Flap -- Fistula Laser Closure -- Fistulectomy -- Fistulotomy -- Flap -- Glue and Paste Injection -- How to Drain an Abscess -- Ligation of Intersphincteric Fistula Tract (LIFT) -- Quality of Life Following Anal Fistula Treatment -- Risk Factors for Recurrence and Incontinence After Anal Fistula Surgery -- Stem Cells in Cryptoglandular Anal Fistulas -- Treatment by Over-The-Scope Clip -- Utility of Adding Marsupialization to Fistulotomy -- Utility of Adding Sphincter Reconstruction to Fistulotomy/Fistulectomy -- Video-Assisted Anal Fistula Treatment -- Evidences for optimal surgical management of anal fistulas and abscess -- Future directions in surgical approach of anal fistulas and abscess -- Integration of surgery with medical therapy in treating anal fistulas: when and how? -- New perspectives in the treatment of anal fistulas: stem cells -- Ostomy and Proctectomy to treat anal fistulas and abscess; when and why? -- Patients? quality of life during and after treatment of anal fistulas and abscess -- Treatment of anal fistulas and abscess: when does surgery come first? -- Anastomotic dehiscence and fistulization -- Best Surgical Strategy to Treat Anal Fistula and Abscess: A Comprehensive Meta-Analysis of Literature -- Fournier Syndrome -- Real Practice in the Management of Anal Fistula and Abscess: Results of a Worldwide Survey as Related to the International Guidelines -- Recto-vaginal and recto-urethral fistulas. 330 $aThis volume comprehensively describes the anatomy, pathophysiology, diagnostics, and modalities of treatment of one of the most complex and debated clinical conditions in coloproctology: anal fistulas and abscesses. It also debates current controversies and presents the best approaches based on the authors? clinical expertise. Providing an in-depth understanding of the anal canal anatomy and surrounding area, it enables readers to manage anal sepsis and avoid excessive damage, in particular to the anal sphincters. Further, the book presents insights into the pathophysiological processes (in cryptoglandular and Crohn?s disease) causing abscess and fistula, which have a significant impact on the management of these conditions. It also discusses diagnostic assessments crucial for selecting the optimal surgical technique and offers guidance on the timing. Lastly, it assesses the pros and contras of the various surgical procedures, evaluating the possible outcome in terms of both therapeutic success and detrimental effects on the anorectal functions. As such it is a valuable resource for all physicians involved in the management of anal fistulas and abscesses (coloproctologists, general surgeons, gastroenterologists, radiologists). . 410 0$aColoproctology,$x2511-8161 606 $aSurgery 606 $aMedical sciences 606 $aInternal medicine 606 $aRadiology 606 $aSurgery 606 $aHealth Sciences 606 $aSurgery 606 $aInternal Medicine 606 $aSurgery 606 $aRadiology 606 $aMalalties de l'anus$2thub 606 $aFístules$2thub 608 $aLlibres electrònics$2thub 615 0$aSurgery. 615 0$aMedical sciences. 615 0$aInternal medicine. 615 0$aRadiology. 615 14$aSurgery. 615 24$aHealth Sciences. 615 24$aSurgery. 615 24$aInternal Medicine. 615 24$aSurgery. 615 24$aRadiology. 615 7$aMalalties de l'anus 615 7$aFístules 676 $a617.555 676 $a617.555 702 $aRatto$b Carlo 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910568257403321 996 $aAnal Fistula and Abscess$92852959 997 $aUNINA
