Prenatal ultrasound signs of Aarskog‐Scott syndrome in a twin pregnancy: A case report
Full text linkL'induzione della crescita follicolare nelle donne con anovulazione [Ovulation induction in anovulatory women]
No full textOvulation induction therapy is administered to stimulate follicular growth and induce ovulation in anovulatory infertile women. In anovulatory women with polycystic ovary syndrome, the treatment of choice is clomiphene citrate, whereas in clomiphene nonresponders, gonadotrophins are given as secondary therapy. Currently, insulin-sensitizing agents are used in the treatment of polycystic ovary syndrome to restore menstrual cyclicity. In selected patients, laparoscopic drilling has also been suggested. In anovulatory patients affected with hypogonadotropic hypogonadism, treatment is based on gonadotrophin replacement therapy or pulsatile gonadotrophin-releasing hormone infusion. In ovulation induction therapy the clinician's attention should be directed at restoring normal ovary function. When pharmacotherapy is required, monofollicular growth should be induced to reduce the risk of multiple pregnancy
Cervical nitric oxide metabolite levels and clinical variables as predictive factors of high-grade cervical intraepithelial neoplasia
No full textTo create a prediction model of high-grade cervical intraepithelial neoplasia (CIN) based on clinical variables and the cervical nitric oxide metabolite (NOx) levels of study participants.This comparative study included 694 women undergoing colposcopy due to abnormal pap smear results. On the basis of the cervical biopsy results, the women were divided into the a parts per thousand currency signCIN 1 or CIN 2-3 group. The two groups were compared in terms of cervical NOx levels and clinical variables. Univariate, multivariate, and receiver-operating characteristic curve analysis were performed.Multivariate analysis showed that CIN 2-3 associated with more than two cervical biopsies [odds ratio (OR) = 5.16], high-grade squamous intraepithelial lesion cytology (OR = 16.19), condom non-use (OR = 4.28), cervical NOx levels a parts per thousand currency sign99.9 mu mol/L (OR = 16.62), more than four lifetime male sexual partners (OR = 10.56), and age at first coitus of a parts per thousand currency sign15 years old (OR = 3.54). This combined model had a sensitivity of 86.49 %, a specificity of 90.74 %, a positive predictive value of 64.0 %, and a negative predictive value of 97.2 %.In the present sample, high-grade CIN associated with decreased cervical NOx levels. Thus, along with some clinical variables, cervical NOx levels may be an additional marker of cervical dysplasia
Seminal plasma total antioxidant capacity and semen parameters in patients with varicocele
No full textTotal antioxidant capacity (TAC) was evaluated in the seminal plasma of infertile patients with varicocele in relation to their semen parameters. The study recruited 60 patients affected by varicocele and 10 fertile non-varicocele subjects as controls. Controls had normal semen parameters and proven fertility. On the basis of semen parameters, patients with varicocele were grouped into normozoospermic (n = 12), asthenozoospermic (n = 8), oligoasthenozoospermic (n = 40). The group with oligosthenozoospermia was divided into mild (<20 à 106/ml; ⥠15 à 106/ml),moderate (<15 à 106/ml; â¥5 à 106/ml), and severe (<5 à 106/ml), based on sperm count. Antioxidant activity was measured in seminal plasma and peripheral blood using the free oxygen radicals defence test. No significant differences were observed in peripheral blood TAC concentrations between controls and groups. In patients with varicocele and moderate oligoasthenozoospermia or severe oligoasthenozoospermia, seminal plasma TAC concentrations were significantly lower (P < 0.05) than in controls and normozoospermic patients with varicocele. Moreover, in patients with severe oligosthenozoospermia, seminal plasma TAC concentrations were also significantly lower (P < 0.05) than in asthenozoozpermic patients with varicocele. In all subjects, concentrations of TAC showed a positive correlation with sperm concentration (r = 0.93, P < 0.05) and motility (r = 0.92, P < 0.05). © 2009 Published by Reproductive Healthcare Ltd
Development of a nomogram based on markers of ovarian reserve for the individualisation of the follicle-stimulating hormone starting dose in in vitro fertilisation cycles
No full textTo elaborate a nomogram based on markers of ovarian reserve for the calculation of the appropriate starting dose of follicle-stimulating hormone (FSH)
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
