Mass closure of visceral peritoneum at cesarean section. A proposal method
No full textThe non-closure of the visceral peritoneum (VP) is the gold standard in caesarean section (CS). For surgeons convinced of the benefits of VP closuring, we propose an alternative method for VP closure during CS, named by us, "Mass Closure Method" (MCM). According to our experience, this method has already been experimented, as described earlier, in 314 CSs in loco-regional anaesthesia. All CSs in our department are performed using the modified Joel Cohen incision in the Stark CS, with the Munro Kerr way of hysterotomy. During haemostasis in 18 cases, author observed a small sub-peritoneal haematoma (5.7%), solved intra-operatively by singular stitches; 10 women received a bladder flap intraoperative detachment, with an accurate haemostasis (3.1%). No case of bladder flap haematoma was recorded, but only hyperechogenic areas in the vesicouterine space (VUS), to be ascribed to the intra-operatives stitches. The direct incision, no bladder flap formation and not suturing a part of the VP, substantially reduce the VUS surface, consequently decrease bleeding, and prevent a pouch formation. On the basis of the author's experiences, the MCM could represent for obstetrics a safe alternative to the surgical approach during CS, as it cut down operative time, surgical bleeding, BHF formation for the non-bladder flap formation, thus reducing the VUS surface.</

Occiput posterior position and intrapartum sonography
No full textUltrasound has revolutionized the traditional midwife, and semiotics in particular gave a dignity to the unborn child, who is now framed as a patient.
However, the main interest has been on ultrasound fetal malformations and fetal growth, whether normal or pathological, while little interest has been
directed to the delivery event.
Indeed, although the birth is a common phenomenon, few technologies have
been developed for the monitoring of labor. This phenomenon contrasts with
everyday reality. In fact, for example, although fetal distress represents 1–2% of
deliveries, it can be monitored with different instrumental techniques
(cardiotocography, pulse oximetry using Stan®, pH-metry), dystocia affects
about 40% of the deliveries but it is still diagnosed manually, as it was in 1700.
Intrapartum sonography is a relatively new technique; it adds to what is
felt by the fingers as the eye can see objectively the commitment, the descent,
and the rotation of the fetal head in the birth canal. This makes it possible to
follow the labor in a more objective view by midwives and enables early
detection of labor dystocia, allowing timely intervention and reducing maternal
and fetal complications. On the other hand, an objective evaluation of
labor reduces operative deliveries based on a presumptive diagnosis of dystocia,
provides a documentation of labor developments, and enables operators
to lower exposure to possible litigation in case of complications that bring
charges of malpractice. A new ultrasonography area, intrapartum obstetric
ultrasound, has been documented by a growing number of scientific articles
that increase the literature. In fact, it is forming a scientific level, a real “pelvimetric
ultrasound,” that does not replace but strongly supports pelvimetry
by providing clinical support of objectivity and by showing the mechanisms
of parturition in occipito anterior, posterior, and transverse presentations. In
the near future, the literature will be subject to an inevitable revision of the
results obtained from the classical clinical symptomatology alone. This text,
in the authors’ opinion, is easy to consult and offers practical support to those
who operate and work in the delivery room and attempt to better diagnose
physiological from pathological labor and to reduce the inevitable risks
involved in the complex phenomenon that is childbirth. Furthermore, our
work fills a gap in publishing today on a topic of considerable practical interest
that we hope will inspire the attention it deserves
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Selective genetic analysis of myoma pseudocapsule and potential biological impact on uterine fibroid medical therapy.
Full text linkObjective: Mutations in Mediator Complex Subunit 12 (MED12) gene are
typical genomic aberrations, commonly detected in a high percentage of uterine
leiomyomas (ULs). The aim of this investigation was to define the fibroid or
non-tumor origin of uterine leiomyoma pseudocapsule (PC) surrounding
fibroids and its possible therapeutic targets in uterine fibroid management.
Research design and methods: A non-randomized observational study was
performed on 36 women, not subjected to any previous drug treatment,
undergoing laparoscopic intracapsular myomectomy. Specimens of myometrium
(UM), ULs and corresponding PCs were sampled to analyze MED12
gene status, by direct sequencing of exon 2.
Main outcome measures: Defining the status of MED12 gene in PCs associated
to ULs harboring mutations.
Results: PCs always showed a wild type MED12 gene status, even when
associated to a UL harboring a specific MED12 aberration.
Conclusion: The wild-type status of MED12 gene in the PCs indicates the
non-tumoral origin of this structure: it appears as a protective structure for
the healthy tissue that could enhance regenerative mechanisms. The limitations
of this study, as the restrained number of patients, will be solved in
the future extending the analysis to a larger cohort of women, as tester of
such pharmacological treatments on PC
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
