Abstract
We present a case report of laparoscopic management of a spontaneous hemoperitoneum in the second trimester of pregnancy. The patient was a 40-year-old woman at 15 weeks of gestation. At laparoscopic surgery, the hemoperitoneum was evacuated, and the right-sided uterine vessels were closed with diathermocoagulation. Every pregnant woman with severe abdominal pain, vomiting, and imminent hypovolemic shock should be carefully evaluated. After ruling out the most prevalent causes of hemoperitoneum, idiopathic spontaneous hemoperitoneum should be considered. Rapid diagnosis and aggressive fluid replacement together with prompt surgical intervention may be the only chance for a favorable outcome for both mother and child in the presence of such a rare complication. Moreover, in early stages of pregnancy, the laparoscopic approach should be considered but only in the hands of experienced laparoscopic surgeon

Abstract
OBJECTIVE: To describe how a hydronephrosis can lead to a difficult differential diagnosis between endometriosis and retroperitoneal fibrosis.
SETTING: Department of Obstetrics and Gynecology, Sacro Cuore Don Calabria General Hospital, Negrar, Verona, Italy.
PATIENT(S): The history of a 34-year-old woman revealed the appearance of hydroureteronephrosis on the right side at the 35th week of pregnancy. She had an magnetic resonance imaging scan and was diagnosed with a spread retroperitoneal fibrosis. After 2 months, the patient reported the occurrence of pelvic pain, dyspareunia and dysmenorrhea. She was treated with corticosteroids and tamoxifen with no results.
INTERVENTION(S): Laparoscopic surgery. A complete retroperitoneal extirpation was done of an endometriotic nodule of the right broad ligament, near the right ureter (without stenosis).
MAIN OUTCOME MEASURE(S): Reduction of pelvic pain.
RESULT(S): She noticed an important decrease of pain.
CONCLUSION(S): The cause of hydronephrosis could be a physiologic hydroureteronephrosis, which is the most common cause of dilatation of the urinary tract in pregnancy. The pain symptoms of the patients seemed to be linked to endometriosis and not to retroperitoneal fibrosis. Magnetic resonance imaging sometimes does not enable a correct diagnosis between these two pathologies. Fertile women with suspected fibrosis should undergo a diagnostic laparoscopy by an expert surgeon in retroperitoneal surgery
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
Non-human papilloma virus associated adenocarcinomas of the cervix uteri. Cytologic features and diagnostic agreement using whole slide digital cytology imaging
No full textBackground: Non-Human Papilloma Virus associated adenocarcinomas (NHPVAs) are uncommon tumors of the cervix uteri which often show a deceptive morphology. Therefore, their diagnostic assessment may be challenging. Slide digital cytology imaging may be an useful tool to improve cytological diagnostic accuracy. However, this novel technology has not been applied to NHPVAs associated cytologies yet. Methods: The study included 31 whole slide digital cytology cases from 10 women with a proven histological diagnosis of NHPVA. As a control group, three further digital slides, from two women with a histological diagnosis of squamous intraepithelial lesion (SIL), were included. The digitally scanned cytological slides were revised to assess the concordance rate among three observers and to find out the most relevant NHPVA cytological criteria. Results: Overall diagnostic agreement between observers was 67.60% (K = 0.50; P < 0.0001). At the consensus diagnosis 34 cases were re-classified as at least suspicious for glandular lesion (n = 24), SIL (n = 2) and negative (n = 8). The most relevant cytologic features for atypical glandular cells or adenocarcinoma at consensus were evident nucleoli, nuclear overlapping and atypical enlarged nuclei. Conclusions: The diagnosis of NHPVA in digital cytology is feasible using criteria which are also used in conventional microscopy. Our study shows a moderate agreement for the cytological diagnosis of NHPVAs using whole slide digital cytology approach. These results are discussed taking into account the most relevant differential diagnostic issues
Major and minor complications in Veress needle (VN) and direct trocar insertion (DTI) for laparoscopic closed-entry techniques: an updated systematic review and meta-analysis
No full textOBJECTIVE: Direct insertion of the trocar is an alternative method to Veress needle insertion for the creation of pneumoperitoneum. We conducted a systematic review and meta-analysis to compare these two entry closed techniques. DATA SOURCE: A systematic review of the literature was done on PubMed, MEDLINE, Embase, Scopus, and EBSCO. METHODS: The literature search was constructed until May 01, 2022, around search terms for "Veress," "direct trocar," "needle," "insertion," and "laparoscopic ways of entry." This systematic review was reported according to the PRISMA Statement 2020. RESULTS: Sixteen controlled trials (RCTs) and 5 observational studies were included in the systematic review. We found no significant differences in the risk of major complication during the access manoeuvres between DTI and VN: bowel injuries (OR = 0.76, 95% CI: 0.24-2.36, P = 0.63), major vascular injuries (OR = 1.74, 95% CI 0.56-5.38, P = 0.34), port site hernia (OR = 2.41, 95% CI: 0.28-20.71, P = 0.42). DTI has a lower risk of minor complications such as subcutaneous emphysema (OR = 5.19 95% CI: 2.27-11.87, P < 0.0001), extraperitoneal insufflation (OR = 5.93 95% CI: 1.69-20.87, P = 0.006), omental emphysema (OR = 18.41, 95% CI: 7. 01-48.34, P < 0.00001), omental bleeding (OR = 2.32, 95% CI: 1.18-4.55, P = 0.01), and lower number of unsuccessful entry or insufflation attempts (OR = 2.25, 95% CI: 1.05-4.81, P = 0.04). No significant differences were found between the two groups in terms of time required to achieve complete insufflation (MD = - 15.53, 95% CI: - 91.32 to 60.27, P = 0.69), trocar site bleeding (OR = 0.66, 95% CI, 0.25-1.79, P = 0.42), and trocar site infection (OR = 1.19, 95% CI, 0.34-4.20, P = 0.78). CONCLUSION: There were no statistically significant differences in the risk of major complications during the access manoeuvres between DTI and VN. A lower number of minor complications were observed in DTI compared with those in Veress access
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
