Efficacy of vaginal danazol treatment in women with recurrent deeply infiltrating endometriosis
No full textOBJECTIVE:
To describe a safe long-term medical treatment for deeply infiltrating endometriosis, a critical condition characterized by multiple painful symptoms and a high recurrence rate after surgical treatment.
DESIGN:
Prospective study.
SETTING:
University of Siena.
PATIENT(S):
Twenty-one women with deeply infiltrating endometriosis.
INTERVENTION(S):
In a nonrandomized prospective study a low dose of vaginal danazol (200 mg/d) was self-administered for 12 months. After a previous laparoscopic surgery, these patients had reported recurrent severe dyspareunia, dysmenorrhea, and pelvic pain (in five cases also painful defecation).
MAIN OUTCOME MEASURE(S):
Before and every 3 months during the treatment a visual analogue pain scale was used. Transvaginal and transrectal ultrasound examinations were performed before and after 6 and 12 months of treatment. Adverse effects were registered, and serum concentration of cholesterol, triglycerides, aspartate aminotransferase, alanine aminotransferase, glycemia, protein S, protein C, antithrombin III, and homocysteine was evaluated before and after 12 months.
RESULT(S):
Dysmenorrhea, dyspareunia, and pelvic pain significantly decreased within 3 months and disappeared after 6 months of treatment, with a persistent effect during the 12 months of treatment. A relief of painful defecation was also shown. Ultrasound examination showed a reduction of the nodularity in the rectovaginal septum within 6 months. The medical treatment did not affect metabolic or thrombophilic parameters; few local vaginal adverse effects were reported.
CONCLUSION(S):
Vaginal danazol resulted in effective medical treatment for the various painful symptoms in women with recurrent deeply infiltrating endometriosis, and because of the lack of significant adverse effects it may be proposed as an alternative to repeated surger
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Use of a progestogen only preparation containing desogestrel in the treatment of recurrent pelvic pain after conservative surgery for endometriosis
No full textObjective: To assess the effect of a new progestin progestogen only pill (desogestrel) versus an oral contraceptive in the treatment of recurrent endometriosis.
Study design: A randomized prospective clinical study. A group of women with endometriosis (n = 40) who showed recurrent dysmenorrhea and/or pelvic pain after conservative surgery, and did not desire a pregnancy. Continuous treatment for 6 months with desogestrel (75 mu g/d) (n = 20) versus a combined oral contraceptive (ethinyl estradiol 20 mu g plus desogestrel 150 mu g) (n = 20) was performed.
Results: A significant improvement of both pelvic pain and dysmenorrhea was observed following each type of treatment (P < 0.001). The use of desogestrel progestogen only pill was associated with a breakthrough bleeding in 20% patients, while a significant body weight increase was observed in 15% after oral contraceptive.
Conclusions: Both desogestrel and an oral estro-progestinic were effective, safe and low cost therapy of pain symptoms after endoscopic surgery for endometriosis, the former showing an impact on breakthrough bleeding, the later an incidence on body weight increas
Tubal sterilization by laparoscopy or hysteroscopy: which is the most cost-effective procedure?
No full textBy using the activity-based cost/management (ABC/M) system we computed and compared costs needed for laparoscopic tubal sterilization (LTS) and Essure hysteroscopic tubal occlusion (EHTO). We found that total health costs related to consultation and presurgery did not differ between LTS and EHTO; EHTO has low recovery unit costs but is more costly for the operating theater, mainly due to Essure microinserts.

Surgical scar endometriosis after Cesarean section: a case report
No full textBackground. Cutaneous endometriosis is a rare condition. Case report. A 37-year-old woman came to our observation 3 years after Cesarean section for a nodule under the scar that became spontaneously painful during menstrual bleeding. Transabdominal ultrasound examination, serum CA125 determination and histopathological analysis of the nodule were performed. Ultrasound revealed the presence of an oval-shaped hypoechogenic neoformation, while the serum CA125 level was slightly increased, and a diagnosis of endometriosis was confirmed by the histopathological analysis of a surgical specimen. Conclusion. This is an interesting case of surgical scar endometriosis, and the etiopathogenetic mechanism of this location may be explained by a dissemination of endometrial tissue during the Cesarean section. © 2006 Taylor & Francis
Variations on the Author
Get PDF“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
A randomized controlled study comparing harmonic versus electrosurgery in laparoscopic myomectomy
No full textOBJECTIVE:
To compare the effectiveness and safety of harmonic scalpel versus electrosurgery to reduce blood loss during laparoscopic myomectomy.
DESIGN:
Prospective randomized controlled study.
SETTING:
Tertiary referral centers for gynecological care.
PATIENT(S):
One hundred sixty consecutive premenopausal women with symptomatic uterine leiomyomata who were assigned to one of the two treatment groups (a total of 80 patients in each group): treatment with electrosurgery devices with a vasoconstrictive solution (50 mL of saline solution and 0.5 mL of epinephrine [1/2 vial of 1 mg/mL]; group A) or harmonic scalpel (group B).
INTERVENTION(S):
Laparoscopic myomectomy.
MAIN OUTCOMES MEASURE(S):
The global operative time, the time spent for myoma enucleation and for suturing uterine wall defects, and intraoperative blood loss as well as the surgical difficulty degree and postoperative pain at 24 and 48 hours after the laparoscopic procedure.
RESULT(S):
No relevant intra- or postoperative complications were observed in either group. The degree of pain 24 hours after surgery was significantly lower in patients in whom the harmonic scalpel was used. The degree of surgical difficulty did not differ between groups, but the global operative time was significantly shorter in the harmonic scalpel group.
CONCLUSION(S):
The use of the harmonic scalpel for laparoscopic myomectomy is associated with low total operative time, low intraoperative blood loss, and low postoperative pain, with no increase in surgical difficulty
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
