Ultrasound pattern of a rare skin disease: multiple miliaryosteoma cutis
No full textPURPOSE:
Multiple miliaryosteoma cutis (MMOC) is a rare nodular skin disease, characterized by tiny bone nodules in the dermis and subcutaneous tissue, presenting clinically as multiple normochromic papules and nodules, usually on the face. We described the case of MMOC of the face in a woman, ultrasonically evaluated with very high frequency probe.
MATERIALS AND METHODS:
A 45-year-old patient with multiple papules, 3-5 mm in diameter, grouped in the frontal region. Skin ultrasound examination, cutaneous biopsy and laboratory evaluation were performed.
RESULTS:
High-frequency ultrasound showed the presence of multiple hyperechogenic linear and roundish structures, associated by hypoechogenic shadow. The histology revealed a normal orthokeratotic stratified epithelium with fragment of mature lamellar bone localized at level of the reticular dermis. Laboratory evaluation was normal. According to the clinical, pathological, laboratory and instrumental analyses, a final diagnosis of miliaryosteoma cutis (or primary osteoma cutis not associated with Albright's hereditary osteodystrophy) was made.
CONCLUSION:
In case of multiple papules of subcutaneous tissue, the diagnosis of MMOC, although rare, should be considered and high-frequency sonography, identifying the calcifications, suggests diagnosis
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

No full textAbstract
Background Ultrasound (US) and Power Doppler (PD) US are useful tools to study and monitor the patients with
hidradenitis suppurativa (HS).
Objective Describe the PD signal of HS nodules, abscesses and fistulas.
Methods A retrospective analysis of PD in mild, moderate and severe HS patients, collecting all demographic and clinical
data. The lesions were classified according to their US morphology, describing the vascular degree – high, moderate
and minimal – and distribution – peripheral, internal and mixed. Statistical analysis was performed using odds ratio and
bivariate regression.
Results A total of 241 lesions, 62 nodules, 64 abscesses, 99 simple fistulas and 16 complex fistulas, from 61 patients
with HS, were included. Vascular distribution was defined peripheral in 143/241, mixed in 55/241 and internal in 0/241
lesions, regardless the clinical type. Qualitative Doppler showed high vascularization in 44/241 lesions, moderate in 79/
241 and minimal in 75/241, despite the clinical type. All lesions showed resistive index <0.7. Age, disease’s duration, size
of the lesions, high Sartorius score and high BMI showed positive statistical correlation with both PD signal and mixed
vascular distribution. No statistical significance was evidenced for vascular degree measurements.
Limitations US cannot detect lesions <0.1 mm.
Conclusion Vascular distribution of HS lesions can be evaluated by PD with additional relevant information for earlier
and better disease management
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
