Imaging
No full textThe goal of male to female (MtoF) sex reassignment surgery (SRS) is to provide an aesthetically attractive and functional result, which permits the new female effortless intromission, preserving the potential for orgasm. Although many of these patients would benefi t from imaging investigation, either to plan SRS or to manage postoperative complications, imaging is not routinely performed in the standard clinical practice. This likely arises, at least in part, from the lack of confidence of most radiologists with the pelvic anatomy after genital reconfi guration and possible postoperative complications

Imaging of Penile Traumas – Therapeutic Implications.
No full textInjury to the penis may result from penetrating or nonpenetrating trauma. Nonpenetrating injury to the erect penis can produce albugineal tear, intracavernous hematoma or extraalbugineal hematoma from rupture of the dorsal vessels. Nonpenetrating injury to the flaccid penis usually follows blunt perineal traumas producing extratunical or cavernosal haematomas, or cavernosal artery tear followed by high flow priapism. Differential diagnosis between albugineal tear and other penile injuries must be obtained as soon as possible, since early surgical repair of albugineal tear reduces significantly the rate of postraumatic curvature and fibrosis. Ultrasonography (US) is able to detect the exact site of the tear in most patients as an interruption of the thin echogenic line of the tunica albuginea. Other imaging techniques are rarely required in the clinical practice. Color Doppler US is the imaging modality of choice to evaluate patients with high flow priapism. Focal or diffuse cavernosal fibrosis can be identified with US as echogenic areas in the cavernosal bodies. Postraumatic erectile dysfunction can result from fibrotic changes, nerve and vascular impairment or both. Doppler evaluation of penile vasculature is required in young patients with postraumatic impotence before surgical revascularization procedures
A review of the emerging profile of the anti-inflammatory drug oxaprozin.
No full textOxaprozin is a nonsteroidal anti-inflammatory drug characterised by a propionic acid-based structure. It is able to diffuse easily into inflamed synovial tissues after oral administration. Although discovered > 20 years ago, it is now under intensive investigation because of its unusual pharmacodynamic properties. Other than being a nonselective cyclooxygenase inhibitor, the drug is capable of inhibiting both anandamide hydrolase in neurons (median inhibitory concentration [IC50] = 85 micromol/l), with consequent potent analgesic activity, and NF-kappaB activation in inflammatory cells (IC50 = 50 micromol/l). Moreover, oxaprozin induces apoptosis of activated monocytes in a dose-dependent manner, with the effect being detectable at a concentration of 5 micromol/l and reaching the maximum activity at 50 micromol/l. As monocyte-macrophages and NF-kappaB pathways are crucial for synthesis of proinflammatory and histotoxic mediators in inflamed joints, oxaprozin appears to be endowed with pharmacodynamic properties exceeding those presently assumed as markers of classical nonsteroidal anti-inflammatory drug
Variations on the Author
No full text“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
Varicocoele. Classification and pitfalls
No full textBackground Varicocoeles have been considered for a long time potentially correctable causes for male infertility, even though the correlation of this condition with infertility and sperm damage is still debated.Objective To present a summary of the evidence evaluation for imaging varicocoeles, to underline the need for a standardized examination technique and for a unique classification, and to focus on pitfalls in image interpretation.Methods Based on the evidence of the literature, the current role of ultrasound (US) imaging for varicocoeles has been reported and illustrated, with emphasis on examination technique, classification, and pitfalls.Results US is the imaging modality of choice. It is widely used in Europe, while in other countries clinical classification of varicocoeles is considered sufficient to manage the patient. A number of US classifications exist for varicocoeles, in which the examinnation is performed in different ways.Discussion An effort toward standardization is mandatory, since lack of standardization contributes to the confusion of the available literature, and has a negative impact on the understanding of the role itself of imaging in patients with varicocoeles.Conclusion Use of the Sarteschi/Liguori classification for varicocoeles is recommended, since it is the most complete and widely used US scoring system available today.Tubular extratesticular structures resembling varicocoeles, either at palpation or at US, should be identified and correctly characterized
