Ultrasound diagnosis and Doppler monitoring of a pelvic spleen in pregnancy
No full textWe describe a patient with a pelvic spleen diagnosed during
pregnancy and monitored through gestation which we
believe to be the first reported case. A 40-year-old woman
was referred at 8 weeks of gestation because of a chronic
intense pain in the left iliac cavity which had spread to her
lower back. Clinical examination revealed a poorly defined
pelvic mass. Pelvic ultrasound demonstrated a gestational sac
containing a viable embryo whose size was consistent with
the period of amenorrhea. While the splenic area in the left
hypocondrium was found to be empty, a homogeneous and
elongate mass measuring 152
́
123 mm with a maximum thickness
of 53.4 mm was observed in the left iliac cavity above the
uterus. This mass, the ectopic spleen, was monitored by Doppler
velocimetry at monthly intervals until delivery and no variation
throughout gestation was observed; therefore, despite
the occasional occurrence of heavy pain, it was possible to
exclude circulatory complications such as thrombosis or
torsion. Doppler ultrasound proved to be a useful tool for
the differential diagnosis of this rare anatomical variation
Perineal ultrasound in the study of urethral mobility: proposal of a normal physiological range
No full textAbstract The aim of the study was to determine, using
perineal ultrasound, the physiological range for urethral
mobility in normal women. Sixty healthy women were
enrolled. The ultrasound parameters obtained with a
perineal “static” and “dynamic” evaluation method were:
pubic–urethral distance and inclination angle of the urethral
axis. We propose a physiological range of pubic–urethral
distance under stress in young women between 10 and
15 mm, the inclination angle of the urethral axis is between
60 and 100°. In peri–post-menopause women we establish a
non-rigid range of mobility in relation to age and parity:
between 15 and 18 mm for the pubis–urethra distance and
80° and 120° for the angle of the urethral axis. Defining a
range of normality for urethral mobility through ultrasound
is useful for further studying therapeutic choices and help to
identify the surgical correction and post-operative follow-u

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
