Concurrent repair of inguinal hernias with mesh application during transperitoneal robotic-assisted radical prostatectomy: Is it safe?
No full textThe repair of inguinal hernias during Robot-assisted laparoscopic radical prostatectomy (RARP) has been published in several studies, which have demonstrated its effectiveness and safety . Overall, it has been observed that the hernioplasty adds on an average, 12–15 min in total surgical time . No significant difference was found between RARP with or without concomitant hernioplasty, with respect to hospitalization or bleeding complications . This procedure can be performed both robotically or laparoscopically depending on patient and surgeon preference. The two methods used for the hernia repair are total extraperitoneal screen placement (TEP), as well as preperitoneal transabdominal screen insertion (TAPP).
As well as for concurrent cesarean section and hernia repair, repair of inguinal hernias during transperitoneal robotic-assisted radical prostatectomy performed in one session, avoids need for readmission to hospital, is safe, effective, and well accepted. It neither increases the complication rate nor prolongs the hospital stay, with clear advantages for both the patients and the hospital budget
Umbilical metastasis. Current viewpoint
No full textMetastatic cancer of the umbilicus is an uncommon and rare presentation. Named ‘Sister Mary Joseph Nodule’, is typically associated with visceral malignancy. These nodules usually arise from the gastrointestinal or genitourinary tract and may represent the first sign of a previously unknown primary tumor. It not only indicates the presence of visceral malignancy but also reveals the poor prognosis of these malignancies. Physicians need to be aware of this rare clinical condition so that they can promptly diagnose the primary cancer. All umbilical mass lesions should be biopsied to determinate the pathological nature. Clinical experience suggests that an aggressive approach, whenever it is possible, may be considered to offer the patient the best survival probability

Hydrogen absorption processes in Mg(2)Ni-based systems: Thermal and mechanochemical kinetics
No full textMg2Ni/Ni and LaMg2Ni alloy powders were exposed to hydrogen under isothermal and
mechanical treatment conditions. In the former case, the amount of hydrogen absorbed
tends with time to a final asymptotic value. Once such a value has been reached, further
hydrogen absorption can be obtained only by submitting the powders to mechanical processing
in the presence of hydrogen. Hydrogen absorption processes under isothermal and
mechanical treatment conditions exhibited different kinetics and their rates have been
compared on a phenomenological basis starting from kinetic evidences. It appeared that
mechanical treatment enhances the rate of hydrogen absorption by four orders of
magnitude as a consequence of a mix of surface area enlargement, temperature rise and local structural excitation processes

Experimental and Theoretical Studies in Modern Mechanochemistry
No full textMechanochemistry is the branch of Chemistry focusing on the chemical
reactivity of solid substances submitted to the application of mechanical
forces under either elastic or plastic deformation conditions. A measure of
its ancestral roots is given by the many citations to mechanochemical
procedures in documents dating back to the Classical Roman Age. Quite
noticeably, even then such learning was referred to as remarkably ancient.
Other important tracks occasionally emerged during the Middle Age, when
the so-called via caloris of Alchemists dreaming the transmutation of matter
overwhelmed the slow comminution of powders in cold stone mortars. Yet,
Mechanochemistry only apparently was sunk in oblivion. The ancient
learning survived through the centuries, and was brought back to life by the
insatiable curiosity of little and great scientists.
After decades of continuous efforts, we are now aware that some of the
most important properties of materials in high-technology applications are
strongly influenced, or even controlled, by mechanochemical phenomena.
The interplay between mechanical stress and chemical reactivity lies for
example at the basis of the corrosion behavior as well as in metallic glasses
and ceramics where local atomic strain plays a critical role in structural
failure. At last, the entire field of Materials Science no longer ignores the
fascinating properties of mechanochemical reactions.
In contrast to their scientific and technological importance, our basic
understanding of even the simplest mechanochemical processes is at best
rudimentary. A deeper understanding and control of elementary processes in
Mechanochemistry is therefore needed. To call attention on the considerable
opportunities existing in this area of fundamental and applied research on
materials, we highlight in this book a number of past achievements and
promising recent developments in the field.
It is today widely accepted that only a highly interdisciplinary approach
holds the greatest promise to provide novel insight into the fundamental
features of physical, chemical and mechanical processes in the various
fields of Materials Science. The same is true for Mechanochemistry. As a
whole, the “mechanochemical” community is as diverse as virtually any
other in materials research, involving disciplines as disparate as
fundamental Physics and Chemistry on the one hand, and Engineering,
Physical Metallurgy and Physical Ceramics on the other. Yet, it is rare that
this diverse pool of expertise is ever brought together in a focused attack on
mechanochemical phenomena and properties. It is our hope that this volume
could give the reader a sense of the rich and fertile common ground which
already exists between the different disciplines, giving thus a contribution to
bring these very different communities closer together.
A central theme in much of the ongoing work on Mechanochemistry
concerns the interrelation between the chemical properties and the
underlying structure of materials. While for a number of scientific research
subjects many suitable experimental techniques for the characterization and
investigation of properties and processes have become available in recent
years, Mechanochemistry still poses a major challenge. This is mostly due
to the fact that in a general mechanochemical process only a small fraction
of atoms is directly affected. It is precisely this inhomogeneity that
undermines any effort to characterize in more detail the mechanochemical
process.
In organizing this book we soon realized that any attempt to cover a
wide field of research such as Mechanochemistry would necessarily
represent a highly selective endeavor. There are many ways of classifying
the contributions offered by the different authors that can be in principle
chosen. For example by distinguishing theoretical from experimental
studies, microscopic from macroscopic investigations, or fundamental from
applied research. The latter distinction appears to be particularly meaningful
for two reasons. First, because the methodologies required for the
investigations are fundamentally different. Second, because of the necessarily
different aims of the works. Nevertheless, a clean-cut separation between
fundamental and applied contributions is often difficult to find, thus the
chosen classification of contributions may not be the most satisfactory one.
Following the aforementioned distinction between fundamental and
applied research, the first part of the book is devoted to contributions
dealing with the fundamental features of Mechanochemistry, including
thermodynamic as well as kinetic and atomistic studies. By contrast with the
emphasis on fundamentals, the second part is instead dedicated to a variety
of applications of mechanochemical methods devoted to the preparation of
inorganic and organic materials and to the processing of minerals and
wastes. The two parts of the book are opened by two introductory chapters.
The former focuses on materials properties and chemical reactions under
well-controlled and well-defined loading conditions, so introducing most of
the fundamental concepts. The latter offers instead an overview of the
reactivity enhancement promoted by the mechanical treatment in various
apparatuses.
