No full textAdipose compartments of the upper eyelid: anatomy applied to blepharoplasty: reply.
No full textMany authors have indicated the presence of ectopic or accessory upper eyelid fat pads, but the effective rate of eyelid fat variations and the corresponding clinical features are still unclear. The purpose of this study was to evaluate the variability of upper lid fat and to define the anatomical landmarks of the adipose pockets of the upper lid. From January of 1998 to January of 2002, the authors investigated the upper eyelid fat compartments of 47 patients who underwent upper blepharoplasty. To support surgical findings, 11 fresh cadavers were also investigated; the anatomy of the intraorbital fat and of the upper eyelid fat compartments was reviewed. Ten patients (21.3 percent) showed an accessory fat pad in the upper lid, which was found on both sides in nine cases. In all patients, the third fat pad was situated lateral to the two classic compartments described by Castanares, behind the orbital septum. Surgical dissections demonstrated that this fat pad derived from the preaponeurotic fat. Anatomical dissections in three cadavers demonstrated an accessory fat compartment protruding under the inferior border of the lacrimal gland. This protruding fat derived from the preaponeurotic fat in all cases and might justify the clinical appearance of a bulge or fullness in the lateral third of the upper eyelid. In the authors' experience, the presence of an accessory upper eyelid fat pad was a frequent finding during blepharoplasty; it could be found and actually resected in about 21 percent of all cases. Surgical and experimental findings put this element as a lateral physiological extension of the preaponeurotic fat that can anteriorly protrude under the inferior border of the lacrimal gland toward the orbital septum. The clinical appearance may be a bulge or fullness in the upper eyelid, and its resection can better define the lateral one third of the supratarsal fold
Order and randomness in Kolmogorov–Johnson–Mehl–Avrami-type phase transitions
No full textThe distribution of points on a 2D domain influences the kinetics of its coverage when a
growth law is attached at each point. This implies that the kinetics of space filling can be
adopted as a descriptor of the degree of order of the initial point distribution. In this paper, the
degree of order of an initial array of points has been changed following two paths: (i) from a
regular square lattice, through increasing displacement assigned to each point, towards
Poissonian disorder; (ii) from a Poissonian distribution, by introducing a hard core potential
with increasing correlation lengths, towards a more ordered lattice. A linear growth law has
been attached to the points of the initial array and the kinetics X.Xe/, where Xe is the extended
coverage as defined in the Kolmogorov–Johnson–Mehl–Avrami model, has been monitored.
The quantitative analysis has been performed by fitting the kinetics to an equation which we
propose for the first time and which has proved to be, in fact, highly suitable for the purpose.
The results demonstrate that the gross of variation from order to disorder is obtained for point
displacements, u, of the order of a, the latter being the constant of a square lattice. Vice versa,
the introduction of a correlation distance in a random distribution provokes at most an order
limited to the first neighbors and no real order can ever be reached. Others descriptors have
been investigated, all confirming our results. We also developed an analytical description
based on the use of the f -functions, as have been defined by Van Kampen, up to the second
order terms. Such a description has been shown to work well for u=a < 1 within an interval
1Xe which depends on the value
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
Cystitis glanduralis complicating an eosinophilic cystitis: A case report
No full textWe report on a rare case of cystitis glandularis complicating an eosinophilic cystitis in an adult. Complaints at presentation included dysuria, haematuria and abdominal pain. Ultrasound and cystoscopy suggested a bladder tumor. Histological analysis of bladder biopsy showed the typical findings of cystitis glandularis associated with eosinophilic cystitis. The patient was treated with transurethral resection of the lesion and a combination of corticosteroids and anthistaminics for three months. He is disease-free at 24 months of follow-up
Adipose compartments of the upper eyelid: anatomy applied to blepharoplasty
No full textMany authors have indicated the presence of ectopic or accessory upper eyelid fat pads, but the effective rate of eyelid fat variations and the corresponding clinical features are still unclear. The purpose of this study was to evaluate the variability of tipper lid fat and to define the anatomical landmarks of the adipose pockets of the upper lid. From January of 1998 to January of 2002, the authors investigated the upper eyelid fat compartments of 47 patients who underwent upper blepharoplasty. To support surgical findings, 11 fresh cadavers were also investigated; the anatomy of the intraorbital fat and of the tipper eyelid fat compartments was reviewed. Ten patients (21.3 percent) showed an accessory fat pad in the upper lid, which was found on both sides in nine cases. In all patients, the third fat pact was situated lateral to the two classic compartments described by Castanares, behind the orbital septum. Surgical dissections demonstrated that this fat pact derived from the preaponeurotic fat. Anatomical dissections in three cadavers demonstrated an accessory fat compartment protruding under the inferior border of the lacrimal gland.

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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
