Quantitative E.M.G. of E.O.M. in patients with congenital fibrosis of the extraocular muscles (CFEOM1).
No full textCongenital fibrosis of the extraocular muscles (CFEOM) is a relatively rare eye movement disorder typically inherited in an autosomal dominant fashion. Affected individuals show congenital, bilateral ptosis and restrictive external ophthalmoplegia, with their eyes partially or completely fixed in an infraducted (eownward) and strabismic position. It remains unclear whether this disorder results from a primary myopathic or from a neuropathic process, and wherther these two processes can be pathophysiologically related to one another. We performed the electromyography with quantitative analysis (QEMG) of the extraocular muscles (EOM) in three members of a family affected by CFEOM whose disease gene maps to the locus on chromosome 12 (CFEOM1). QEMG data from the EOM of the affected members provides a furgher demonstration of a neuropathic process for CFEOM1 involving the superior and inferior division of the oculomotor nerve
Surgical ancorage of the lateral rectus muscle to the periosteum of the orbit: a new tool to tuckle retraction in Duane syndrome and exotropia in 3rd cranial nerve palsy.
No full textObjective of the present study was to evaluate the possibility of surgically eliminating of any function of the lateral rectus muscle of the affected eye in patients with Duane syndrome with globe retraction in adduction and in patients with complete 3rd cranial nerve paralysis. Surgery was based upon a technique introduced by Alan Scott zhich consists in anchoring the lateral rectus detached from the globe onto the periosteum of the lateral wall of the orbit wigh a non-absorbable 6-0 prolene suture. Two patients with complete 3rd cranial nerve paralysis and one patient with Duane syndrome type I underwent surgery with this technique. Eye position improved in the two patients with complete 3rd cranial nerve paralysis. The patient with Duane syndrome shozed disappearance of globe retraction in adduction. Additional surgery was required to correct esotropia in the patient with Duane syndrome and to improve hypotropia in one patient with 3rd cranial nerve palsy
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 textVariations 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Subtenon triamcinolone acetonide to treat diabetic macular edema.
No full textPurpose: To evaluate the efficacy of Triamcinolone Acetonide subtenon injections in the treatment of diabetic macular edema.
Methods: We selected 11 patients, 8 of which were male, and 3 of which were female, ages ranging between 61 and 74 years old (average 68.3). The patients were all affected by diabetes type II and they presented macular edema previously diagnosed with fluorescence angiography. The patients’ visual acuity was evaluated utilizing the ETDRS logarithm (logMAR), the measurement of intraocular pressure (IOP), and a biomicroscopic examination of both anterior and posterior segments of the eyes. Subsequently, an Optical Coherence Tomography (OCT) was performed using an OCT3 (Zeiss-Humphrey, Dublin, CA).
After a topical 0.4% oxybuprocaine anesthesia, the patients were given a 40 mg peribulbar inferotemporal subtenon injection of Triamcinolone Acetonide. Each patient was given three injections; each injection separated by 30 days. After each injection, the patients were prescribed a topical antibiotic treatment for three consecutive days.
Results: Visual acuity before cortisonic treatment was 0.464+0.112 log with a 16.182+1.4011 mm/Hg. A month after the beginning of the treatment, visual acuity was 0.118+0.125 log (p<0.001) while the IOP was 16.727+1.191 mm/Hg (p<0.147). Twelve months after the end of the treatment, we observed a stabilization of visual acuity and IOP. After three months of treatment, the condition was successfully cured. The OCT results were also stable a year after the treatment.
Conclusions: Utilizing Triamcinolone Acetonide with a peribulbar subtenon injection showed to be an effective solution for diabetic macular edema without showing signs of the complication
