Umstellungsosteotomie am Metatarsalknochen zur Heilung und Prophylaxe diabetisch- neuropathischer Schwielen und Ulzerationen

Die periphere Neuropathie, die am häufigsten beim Diabetes vorkommt, führt über die Beeinträchtigung der Motorik und der Sensibilität zu einer Dysbalance der Fußmuskulatur. Sie begünstigt Fußfehlstellungen wie Hallux valgus, Hammerzehenstellung und das Tiefertreten der Mittelfußköpfchen. Daraus resultiert eine Störung der Abrollbewegung. Bleiben tief stehende Metatarsalköpfchen über längere Zeit bestehen, entwickeln sich zunächst plantare Druckschwielen und später Ulzerationen. Diese führen zu Infektionen des Fußes, die eine Amputation erforderlich machen können. Konservative Behandlungsmethoden können zur Ulkusheilung führen, haben aber eine hohe Rezidivrate. Die operativen Verfahren bestanden bislang v. a. in Resektionen. Diese führen zur Überlastung der Nachbarknochen. Es entstehen an diesen Stellen neue Läsionen, sog. Transferulzerationen. Ziel dieser Arbeit war es, druckentlastende Operationsmethoden mit Erhalt der Metatarsalknochen auf Ulkusheilung und Operationskomplikationen zu untersuchen. Es wurde bei 14 Patienten mit 9 Schwielen und 9 Ulzerationen eine gelenkerhaltende Umstellungsosteotomie am Metatarsale zur Druckreduktion durchgeführt. Alle Läsionen heilten in einem Zeitraum von 2 bis 8 Wochen ab. Postoperative Heilungskomplikationen traten nicht auf. Die Ergebnisse zeigen, dass Neuropathie bedingte Ulzerationen durch druckentlastende Osteotomien an den Mittelfußknochen zur Heilung gebracht werden können, wenn konservative Maßnahmen nicht zum Erfolg geführt haben

TRACK-TWO DIPLOMACY AS A RESOLUTION APPROACH TO INTERNATIONAL AND INTER-SOCIETAL CONFLICTS

ABSTRACT This work provides a descriptive discussion for one of the new conflict resolution approaches, track-two diplomacy. The study discusses both strengths and weaknesses of the approach in detail, concluding that as a part of broader conflict resolution efforts, track-two diplomacy may be very useful, despite its practical shortcomings, to overcome psychological barriers between the parties, to make them understand their issue mutually, to produce new insights for resolution, and to create a psychological maturity for a negotiated agreement. Thus, it is stressed that track-two diplomacy should be utilized to complement formal negotiation process in resolving international and inter-societal conflicts

Usporedba transvaginalnog ultrazvuka, magnetske rezonancije i metode smrznutih rezova u prijeoperacijskom otkrivanju zahvaćenosti miometrija u bolesnica s karcinomom endometrija

We aimed to evaluate the depth of myometrial invasion preoperatively with transvaginal ultrasound, magnetic resonance imaging, and frozen section examination techniques in patients diagnosed with endometrial cancer. Our study included 65 patients. Transvaginal ultrasound and magnetic resonance imaging were performed in study patients in the preoperative period. Frozen section examination was performed in all hysterectomy samples obtained from all study patients. Data were analyzed with SPSS Statistics 22.0 program. The sensitivity of transvaginal ultrasound in determining the depth of myometrial invasion was 88.64%, specificity 90.48%, positive predictive value 95.12%, and negative predictive value 79.17%. For magnetic resonance imaging, the sensitivity was 63.64%, specificity 95.24%, positive predictive value 96.55%, and negative predictive value 55.56%. In addition to the frozen section examination, which is the gold standard in determining the myometrial invasion depth, transvaginal ultrasound and magnetic resonance imaging have become commonly used methods for this purpose in recent years. Ultrasound examination performed by an experienced specialist is superior to magnetic resonance imaging as it is fast, inexpensive, and associated with higher sensitivity.Cilj je bio prijeoperacijski procijeniti dubinu zahvaćenosti miometrija pomoću transvaginalnog ultrazvuka, magnetske rezonancije i metode smrznutih rezova u bolesnica s dijagnozom karcinoma endometrija. Istraživanje je obuhvatilo 65 bolesnica. Transvaginalni ultrazvuk i magnetska rezonancija provedeni su kod ovih bolesnica u prijeoperacijskom razdoblju. Ispitivanje smrznutih rezova provedeno je na uzorcima prikupljenim tijekom histerektomije kod svih bolesnica uključenih u istraživanje. Dobiveni podatci analizirani su programom SPSS Statistics 22.0. Osjetljivost transvaginalnog ultrazvuka u određivanju dubine zahvaćenosti miometrija bila je 88,64%, specifičnost 90,48%, pozitivna prediktivna vrijednost 95,12% i negativna prediktivna vrijednost 79,17%. Za magnetsku rezonanciju osjetljivost je bila 63,64%, specifičnost 95,24%, pozitivna prediktivna vrijednost 96,55% i negativna prediktivna vrijednost 55,56%. Uz metodu smrznutih rezova, koja je zlatni standard u određivanju dubine invazije miometrija, posljednjih godina se transvaginalni ultrazvuk i magnetska rezonancija često primjenjuju za ovu namjenu. Ultrazvučna pretraga koju provodi iskusni specijalist bolja je od magnetske rezonancije, jer je brza, osjetljivija i nije skupa

A Long View of Shareholder Power: From the Antebellum Corporation to the Twenty-First Century

For most of the twentieth century, the conventional wisdom held—probably correctly—that shareholders in America’s large, public corporations were passive and powerless and that managers wielded the real power. Beginning in the 1980s, however, shareholders in the form of institutional investors started to push for a greater say in corporate decision-making. In the twenty-first century, hedge funds have upped the ante, fighting for major changes in corporations whose shares they own. Once-imperial CEOs have now become embattled as they fight, but often lose, against activist shareholders demanding policy changes, new dividends, board representation, and even the sale or break-up of corporations. In short, things have changed. This Article situates the present-day rise of shareholder power by taking a long view of the previous two centuries, moving beyond traditional accounts to reach all the way back to the beginnings of the American business corporation in the early nineteenth century, then following the story of shareholder power up to the present day. Its long view reveals the complicated and shifting nature of shareholder power, documenting how periods of greater shareholder power were interspersed with periods where shareholders had little power, how the focus of shareholder power has moved from controlling shareholders to autonomous managers, and how shareholder power has ebbed and flowed across the last two centuries. This Article not only provides the backstory to present-day developments, but also suggests that what has appeared as a hallmark of American corporate capitalism—the relative powerlessness of shareholders—may only have been typical of a few decades in the middle of the twentieth century.\u3c.p\u3

Real-Time Cyber Attack Detection Over HoneyPi Using Machine Learning

The rapid transition of all areas of our lives to the digital environment has kept people away from their intertwined social lives and made them dependent on the isolated cyber environment. This dependency has led to increased cyber threats and, subsequently, cyber-attacks nationally or internationally. Due to the high cost of cybersecurity systems and the expert nature of these systems\u27 management, the cybersecurity component has been mostly ignored, especially in small and medium-sized organizations. In this context, a holistic cybersecurity architecture is designed in which fully open source and free software and hardware-based Raspberry Pi devices with low-cost embedded operating systems are used as a honeypot. In addition, the architectural structure has an integrated, flexible, and easily configurable end-to-end security approach. It is suitable for different platforms by creating end-user screens with personalized software for network security guards and system administrators
