Sonoisterografia : valutazione della cavità uterina e dello stato tubarico
No full textL’ecoisterosalpingografia (EISG) è una tecnica che consente di studiare la cavità uterina e lo stato tubarico. Tale procedura diagnostica consiste nell’iniettare una soluzione salina (NaCL 0,9%) nella cavità uterina sotto controllo ecografico continuo.
Scopo del nostro studio è di valutare l’efficacia della EISG nella diagnosi della patologia uterina e della pervietà tubarica e di confrontantare i risultati con quelli ottenuti con l’isteroscopia diagnostica e l’ecografia transvaginale.
Abbiamo studiato 221 pazienti infertili, con età compresa tra i 23-44 (media 33.5). Tutte le pazienti sono state sottoposte ad ecografia transvaginale seguita da isteroscopia diagnostica e EISG. Delle 221 pazienti, 155 presentavano anomalie della cavità uterina rilevate all’esame isteroscopico. L’ecografia ha permesso di individuare 105 delle 155 patologie uterine (67.0%). Ad eccezione per un singolo polipo endometriale, la sonoisterografia ha permesso di evidenziare tutte le anomalie (99.3%). Abbiamo inoltre effettuato un isterosalpingografia (ISG) dopo sei mesi circa di intervallo in 53 donne per valutare l’effficacia diagnostica dell’EISG nello studio della pervietà tubarica. Le tube sono risultate pervie in 39 (73.3%) e 41 (77%) casi rispettivamente dopo EISG e ISG. Percio’, i risultati ottenuti con l’EISG risultano essere efficaci se confrontati con quelli ottenuti con gli altri mezzi diagnostici. Tutte le 155 donne hanno ben tollerato l’esame che si effettua in 15 minuti circa (SD 5.6 min) permettendo di ottenere immagini di ottimo livello e qualità. Inoltre l’ EISG permette un precisa programmazione della chirurgia endoscopica e di ottenere un preciso screening delle anomalie dell’endometrio e del miometrio. In casi di mioma sottomucoso da trattare con isteroscopia, ci permette di misurare esattamente lo spessore del miometrio e di formulare una diagnosi immediata perché effettuabile anche nei casi di sanguinamenti uterini. Quindi la EISG è un metodica diagnostica di rapida attuazione, facile da eseguire e non invasiva e consente un risparmio in termini economici. E’ percio’ raccomandabile per la diagnosi di anomalie della cavità uterina e dello stato tubarico
Fertility preservation in female cancer patients: an emerging challenge for physicians
No full textFertility preservation has become an issue of great importance in female cancer patients due
to increasing survival rates and delayed childbearing. It is an emerging challenge for
physicians, cause of several related issues (multidisciplinary approach, doctor-patient
communication, ethical, religious and legal problems) and many unresolved questions.
This review aims to update the latest literature data, summarizing the effects of cancer
treatments on female fertility and the various options currently available to offer cancer
patients the opportunity of future pregnancies.
Many strategies exist for fertility preservation in young women and they should be assessed
according to the patient’s age, type of cancer, partner status and time available. Some
techniques are well established, others are still experimental. The established methods include
embryo cryopreservation, transposition of ovaries prior to radiation therapy, radiation
shielding of gonads and conservative surgical approaches. The experimental methods include
oocyte cryopreservation, in vitro maturation of oocytes, ovarian tissue cryopreservation and
transplantation, and ovarian suppression. Improvement of these techniques as well as better
characterization of their success rates and risks, await further investigation. Oocytes donation
and gestational surrogacy represent the last options.
Thus, the care of these patients is challenging, complex and requires a multidisciplinary
approach. A close collaboration between Oncologists, Specialists in Reproductive Medicine,
Gynecologic Oncologists and Endocrinologists is crucial for always offering the best possible
option
[Hysteroscopic vs histologic diagnosis. Study of 222 cases of abnormal uterine hemorrhage].
No full textAUB (abnormal uterine bleeding) is one of the most common pathologies. It is therefore important to use a method that is easy to carry out in order to ensure a rapid and reliable diagnosis. Hysteroscopy may represent the elective method for the study of the uterine cavity. A total of 222 women suffering from AUB were studied between January 1996 and June 1997 at the Department of Surgery, Gynecology Clinic of L'Aquila University. Their age ranged between 30 and 74 years old. The exclusion criteria for the study were as follows: presence of a genital infection in active or latent phase, pregnancy in progress or abortion. All patients underwent operative hysteroscopy with targeted biopsy accompanied, when necessary, by endometrial ablation. All biopsies underwent histological analysis and the results of hysteroscopic diagnosis and histological diagnosis were then compared. There was a 85% correspondence between results. The main difficulties were encountered in the identification and selection of the characteristics of hyperplasia. Moreover, during the study it was found that hysteroscopy was both diagnostic and also therapeutic since it enabled the removal of polyps and intracavitary fibroma or endometrial ablation if required. Hysteroscopy was therefore found to be a totally reliable method for the study of abnormal uterine bleeding compared to the histological tests carried out
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
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
