Population-based case-control study of essential tremor
No full textCurrent epidemiologic data on the association between environmental factors and essential tremor (ET) are scanty. In a population-based case-control study we investigated the relationship between some putative risk factors and ET. In the present study, we included all subjects identified during a door-to-door prevalence survey in a Sicilian community, affected by ET, and alive on 1 November 1987 (n=31). Of the 31 prevalent cases of ET, we were able to contact 28 subjects. Twenty-eight controls were randomly selected from the general population and matched to each case for age and sex. Exposure variables were investigated by interviewing the patients and their controls or close relatives, using a structured questionnaire. The odds for habitual alcohol consumption were 0.3, indicating a protective effect. The odds for exposure to agricultural chemicals and domestic animals were 2.5 and 2.7, respectively, suggesting a role as potential risk factors. However, the associations found by us were not statistically significant. © Springer-Verlag 1998
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
Bilobed placenta and management choices: literature review and two cases studies
No full textObjective. Bilobed placenta is a placental morphological variation with an
estimated incidence of 4% of all pregnancies. It is associated with an increased
risk of cord insertion anomalies and vasa previa. We searched the literature,
focusing on the diagnosis, management, and particular aspects of cases of
bilobed placenta. Moreover, we described our experience with two cases of
bilobed placenta.
Materials and Methods. A literature search was conducted from January 2011
to January 2022. We selected all clinical studies in English, investigating the
diagnosis and management of cases of bilobed placenta. Moreover, we reported two cases of a bilobed placenta.
Results. Ten papers were included in the review: 7 case reports, 1 cross-sectional
study, 2 retrospective analysis. Based on the type of found articles, the quality of
evidence is limited, mainly on the pathophysiology and aetiology of this anomaly. Moreover, our search showed a significantly lower incidence compared to the
literature. About our reported two cases of a bilobed placenta associated with
anomalous cord insertion: case 1, characterized by a velamentous cord insertion,
case 2, with a marginal previa placenta associated with vasa previa.
Conclusions. A close ultrasound follow-up should be performed in case of
suspicion of bilobed placenta to confirm the morphology and proximity to
the cervix, assess the umbilical cord’s insertion and to identify other eventual
associated anomalies. The management should be carried out by a dedicated
team of specialists with experience with placenta abnormalities to reduce the
risk of adverse foetal and maternal outcomes
Is Vaginal Laser Effective for Overactive Bladder? Results of a Systematic Review
No full textPurpose of Review: The aim of this review is to determine the efficacy of laser treatment in overactive bladder (OAB) syndrome in women. Recent Findings: In international literature, there are few studies focusing on OAB symptoms. The proposed treatments included thulium laser, fractional CO2 laser and Erbium:YAG laser. Summary: Although the analysed studies are not RCTs, the results show the efficacy of laser treatment in OAB symptoms, also compared to conventional medical and surgical treatments. However, these tests must be implemented with RCTs and with large patient samples
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
Long and fluctuating bone fragments in uterine isthmus: A curious feature of true osseous metaplasia
No full textOsseous metaplasia in the uterine cavity is a rare phenomenon arising from an unusual transformation of non-osseous connective tissue into mature bone. It is unclear how this alteration occurs and it has no single clinical manifestation. We report a case of asymptomatic endometrial osseous metaplasia of the isthmus with a singular picture: numerous long, floating bone-like structures in the cavity. The lesion was treated by operative hysteroscopy. Histological findings described a rare picture of true osseous metaplasia with the extraordinary presence of cells referable to areas of hematopoietic tissue in the cavities of trabecular bone. Physicians should be more informed and alert regarding this rare disorder in all its strange shapes and localizations, so as to be able to follow suitable therapy. © 2014 The Authors.

Attitudes of mothers of preadolescent girls on HPV vaccine in Italy: do we need a turning point?
No full textBACKGROUND: To investigate the knowledge, awareness and attitude of mothers of pre-adolescent girls regarding the HPV vaccination and cervical cancer, and to understand how to improve the efficacy of the Italian vaccination campaign through the gathered data.METHODS: A questionnaire-based survey was conducted in mothers of unvaccinated 9 to 12-year-old (yo) girls in Italy from November 2018 to July 2019, to evaluate their awareness and the attitude toward HPV, its vaccination and the information sources of the vaccination campaign. The selection of the distribution sites of the questionnaire was performed with randomization of 50 major places of aggregation located throughout the Italian territory. RESULTS: Three hundred mothers of unvaccinated girls were included in the study and divided into two groups (191 subjects <45yo, 109 subjects >45yo). Results showed that 79.6% of <45yo knew what HPV is, compared to 60.6% of >45yo (p-value <0.001); only 60.2% (<45yo) and 54.1% (>45yo) showed awareness about the HPV vaccine (p-value 0.03). The percentage of parents against vaccination in pre-adolescent was higher in the >45yo (29.4%); however, most of them appeared favorable to the information campaigns regarding the vaccine (p-value <0.001). CONCLUSIONS: Our study showed that mothers of unvaccinated pre-adolescent girls have suboptimal knowledge on the topic. Moreover, the implementation of communication strategies dedicated to the population segment appears as a central aspect. As HPV vaccination keeps being a public health concern, it is fundamental to understand which trigger should be managed by healthcare decision makers in order to boost the vaccination campaigns
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
Burkitt's lymphoma in pregnant woman: Difficult management of a rare case
Full text linkIntroduction: Burkitt's lymphoma (BL), an aggressive subtype of non-Hodgkin lymphoma (NHL), is extremely rare during pregnancy. In the case of bowel localization, diagnosis can be very difficult. Moreover, signs and symptoms of the primary small intestine lymphoma are nonspecific, mostly attributable to the “mass effect” of the tumor. The most frequent symptom is abdominal cramp-like pain, associated with nausea and vomiting. Presentation of case: We report a rare case of a 37-year-old pregnant woman, at the 33rd week of gestation, with an abdominal-pelvic mass of uncertain nature. Surgical strategy consisted of a two-step procedure, which involved a cesarean section and typing of the mass: extemporaneous examination hypothesized intestinal lymphoma. The definitive histological examination confirmed the diagnosis of rare case of BL in pregnancy. Discussion: The clinical case reported, representing a rare occurrence of BL in pregnancy, was associated with difficult interpretation and complex management. Lymphoma of the small intestine is often overlooked in the early stages of the disease, due to the fact that symptoms are non-specific and consequently underestimated. In our case, based on gestational age, it was possible to perform a multidisciplinary approach, a cesarean section with surgical intestinal exploration, achieving at the same time delivery of the child and a definitive diagnosis of BL with intestinal involvement. Conclusion: The involvement of multiple professionals is undoubtedly the best way to deal with the above referred to situation, with the main point being to keep in mind the possibility of this type of occurrence
