acute onset of ocular hypertension in myopic patient with pigment dispersion syndrome mimicking uveitis
Full text linkAbstract
Purpose:
To report the acute onset of ocular hypertension in myopic patient with pigment dispersion syndrome.
Methods:
A 40-year-old male patient, suffering from unresponsive chronic open-angle glaucoma in multi drugs-
therapy, underwent complete ophthalmological evaluation at our department in order to have a second opinion on
his pathology.
Results:
Visual acuity was 20\20 in both eyes, gonioscopy showed the presence of iris pigment in the
iridocorneal angle (Grade 4 Shaffer classification) and an iris anterior concavity. The intraocular pressure (IOP), in
spite of the topical therapy, was 28 mmhg; the anterior chamber was normal without Tyndall phenomenon, while the
retina and optic disc were normal. The patient underwent a bilateral YAG laser peripheral iridotomy and a bilateral
Selective Laser Trabeculoplasty (SLT). After a two-year- follow up, the visual acuity is stable and the IOP is set on
12 mmhg in both eyes (instilling one drop of 10 daily).
Conclusion:
In the myopic patient the pigmentary glaucoma is a complication which has to be and often causes
misdiagnose
The impact of migrant remittances on economic and social welfare in municipalities of El Salvador:
No full textIn order expand the body of knowledge on the impacts of international migration on developing nations, this dissertation examines the effects of transnational migration and migrant remittances on communities in El Salvador. The effects of migration on the migrant-sending country can be dramatic on both a macro and microeconomic level, which create serious challenges for governments, communities and families. As one of the world economies most heavily dependant on remittances from the United States and also a country whose most vital export has become its human capital in the form of migrants, this study of El Salvador can serve as a case study to be applied to illustrate the potential situations and opportunities in other nations. Data from the 2004 national census and from a 2005 UNDP study were used to construct several regression models to determine the incremental impact of migrant remittances on poverty, health, education level attained, workforce participation, life expectancy, crime and gender roles in households across El Salvador. The results revealed that the dollar amount of remittances has a statistically significant positive relationship with a number of quality of life variables, such as reduced unemployment in households, higher average grade level and higher life expectancy; however, this variable was also correlated with increased cases of malnourishment in children. A similar variable, the percent of people receiving remittances, which represents penetration of migrant remittances throughout communities, had a statistically significant inverse relationship with several of the same quality of life variables, such as lower average grade level, lower levels of malnourishment and decreased life expectancy. The reasons for these differences are examined, including the possibility that while dollar amount of remittances may ease financial constraints and improve certain conditions for households, the psychological effects of widespread migration may exert a different and sometimes opposite effect. A review of relevant research determined that while globally there have been attempts at policy shifts towards channeling remittances into more productive, the majority of remittance income is spent on immediate consumption, which presents opportunities for intervention by both the public and private sector to encourage more sustainable use of remittances.Ph.D.Includes bibliographical references (p. 173-180)by Mary Kate Roman

COGAN'S SYNDROME: CASE REPORT.
No full textLa S. di Cogan è una patologia sistemica immuno-mediata con frequente interessamento di strutture oculari e audio-vestibolari. Sebbene la cheratite interstiziale in assenza di cause infetti-ve è la classica forma di interessamento oculare, possono rinvenirsi anche altre cause non infiam-matorie oculari. Il danno audio-vestibulare è difficile da trattare e può concludersi con una profonda perdita dell'udito. Scopo del lavoro è quello di illustrare un raro caso clinico di S. di Cogan in un paziente di 28 anni

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
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
