MAY ENDOMETRIOSIS BE CORRELATED WITH STRESSFUL LIFE EVENTS AND PSYCHIATRIC DISORDERS? THE ROLE OF SEROTONIN TRANSPORTER GENE PROMOTER POLYMORPHISM
Avoiding Inappropriate Surgery on Undetermined Mass: May the Combination of Magnetic Resonance Imaging (MRI) and Ovarian Markers Be Helpful?
In order to avoid inappropriate surgery on an ovarian mass, it is essential to correctly classify the mass whether benign or malignant. The aim of the study is to evaluate diagnostic accuracy of MRI associated to human epididymis protein 4 (HE4) and carbohydrate antigen 125 (CA-125) serum levels in discriminating benign and malignant ovarian masses
Endometriosis and Glanzmann's thrombasthenia
Glanzmanns thrombasthenia (GT) is a rare bleeding syndrome characterized by deficiency or defect of platelet aggregation complex. The pathogenesis of endometriosis is controversial but the strongest evidence leans towards retrograde menstruation. GT probably predisposes to endometriosis. The management of women affected by this disease can be difficult due to the risk of bleeding complications, especially during surgical treatment. We describe the cases of three sisters affected by endometriosis and GT, referred to our Department, who received different therapeutic management
Olaparib, PARP1 inhibitor in ovarian cancer
Ovarian cancer is the most important cause of gynecological cancer-related mortality. Conventional treatments for advanced or recurrent disease offer limited results in terms of long-term responses and survival. Researches have recently focused on target therapies, which represent a new, promising, therapeutic approach, able to maximizing tumor kill and minimizing toxicity. The family of polyadenosine diphosphate-ribose polymerase (PARP) inhibitors is currently one of the most hopeful and investigated alternatives. Preclinical and clinical studies of Olaparib , the most investigated PARP inhibitor in ovarian cancer, are analyzed and discussed. Data were obtained by searching for all English peer-reviewed articles on Medline, on Cochrane Database and all on-going Phase I and II studies registered on National Cancer Institute Clinical Trials; also any related abstracts recently presented on Olaparib at major international congresses will be included. Bad prognosis and drug resistance usually affect ovarian cancer. Recent trends toward the knowledge of molecular-specific pathways have produced new target drugs. PARP inhibition mediated by Olaparib in BRCA1 (breast cancer 1) and BRCA2 (breast cancer 2)-mutated and in sporadic ovarian cancer represents a promising field of investigation. Further studies are needed to confirm initial exciting results
Cervical cancer: are there potential new targets? An update on preclinical and clinical results
According to international guidelines, treatment of cervical cancer (CC) consists of surgery in early stages and of chemoradiation in locally advanced disease. Metastatic disease is usually treated with palliative chemotherapeutic regimens, but cytostatic drugs present significant side effects and show limited activity. Thus, the discovery of new anticancer agents, interfering with molecular targets expressed by the tumor’s microenvironment or by the tumor cell itself, represents a possible chance for the struggle against this tumor. The aim of this review is to report all targets that have been investigated in preclinical and clinical studies. We discuss these potential targets according to “targeted therapies” NCI classification. The most investigated molecular targets have been epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF), both involved in CC etiopathogenesis. Studies with anti-angiogenetic agents showed encouraging clinical efficacy and acceptable toxicity. Other interesting results have been obtained by immunotherapeutic strategies. Since biological characteristics of CC, especially in recurrent disease, are still partially unknown, future studies are necessary to understand mechanisms involved in CC carcinogenesis, in order to give to patients the most tailored and efficient treatments
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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

Variations on the Author
“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
