Is it time for midwives to do intrapartum ultrasound in the delivery ward?
Full text linkIn the last 40 years, intrapartum ultrasound (IU) has been a technique often used in the delivery ward. Many studies are reported in literature about it. According to literature, the IU improves especially the diagnosis of fetal head position (FHP) during the labor, in comparison with traditional digital vaginal examination (DVE). ISUOG practice guidelines highlighted high levels of evidence and grades of recommendation, in particular for the sonographic confirmation of FHP in the pelvis before OVD.
IU is currently used in the delivery room for FHP labor diagnosis with VE. The caput succedaneum in labor limits the DVE of FHP diagnosis because reduces the digital examinations of sutures and fontanels. Some authors demonstrate that angle of progression (AOP), head-perineal distance (HPD), and head-symphysis distance (HSD) are important to determine fetal head station during labor.
It is time for IU use by midwives together with obstetricians because it improves the traditional VE in the FHP diagnosis
Malformazioni fetali dell'apparato scheletrico ecograficamente misconosciute: profili di responsabilità professionale
No full textPrendendo spunto da due casi peritali, gli Autori esaminano la complessa materia della responsabilità professionale da omessa diagnosi di malformazioni fetali dopo ecografia ostetrica. La maggior parte delle anomalie (specie dell'apparato scheletrico) sono identificabili a partire dal secondo trimestre di gravidanza e tale condizione rende quanto meno problematico, se non impossibile, il giudizio a posteriori sulla esperibili di un intervento ai sensi della Legge 194/78. La discussione si sofferma anche sulla ondivaga giurisprudenza di merito che, nel solco della Suprema Corte, ha sostituito il criterio di certezza del rapporto di causa-effetto con quello di probabilità dello stesso e, nella fattispecie, addirittura con il criterio di mera possibilità
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
["Defensive medicine" in the choice of cesarean section]
No full textAim: To evaluate the perception of "Defensive Medicine" by hospital obstetricians and the influence of this attitude on the choice of cesarean delivery. Methods: Questionnaire sent by mail to a sample of obstetricians of general district, teaching and university hospitals in a region of southern Italy (Puglia). Doctors were selected as the head, the senior and the junior specialist of each department. Independent variables of the-study were considered as demographic data of the subjects, seniority, interest in private practice, size of the hospital, background cesarean section rate, personal and site of work exposure to legal claims. Outcome measures were experience and confidence in training for operative vaginal and breech delivery, use of the partogram in labour, opinion about a trial of labour after a previous cesarean section and about section on request, personal perception of Defensive Medicine. Univariate and multivariate analysis of data were performed. Results: The response r..
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
Reversal of foetal hydrops and foetal tachyarrhythmia associated with maternal diabetic coma.
No full textFoetal hydrops is always a challenge for the clinician. We report a case of tachycardia associated with hydrops and hydramnios in a pregnancy complicated with diabetic coma at 28 weeks gestation. Normal foetal heart rate was recorded immediately after correction of maternal acidotic status and hydrops eventually disappeared. The woman was delivered at 32 weeks and the baby had an uncomplicated postnatal course. We hypothesise that maternal ketoacidosis has been the precipitating factor of tachycardia and congestive heart failure and that this case is conceptually similar to the "late death" phenomenon, reported in cases of poorly controlled maternal diabetes
