Neuritis of the sensory branch of the radial nerve. Wartemberg's syndrome. A case report.
No full textWartembergs syndrome is an entrapment of the sensory branch of the radial nerve in the forearm. It is not mentioned with the other peripheral nerve entrapments and it is very rare. Wartemberg's syndrome is too often misdiagnosed as the De Quervain's disease or is not diagnosed at all. The Authors report their experience with a case surgically treated
THE PILLAR PAIN IN THE CARPAL TUNNEL'S SURGERY. NEUROGENIC INFLAMMATION? A NEW THERAPTIC APPROACH WITH LOCAL ANAESTHETIC.
No full textAIM: After the surgical decompression of the transverse carpal ligament as treatment of the tunnel carpal syndrome, pillar pain manifestation is possible. This is a painful and temporary invaliding syndrome with unknown aetiology. Aim of the study is to demonstrate that pillar pain is based on autonomic irritation that disappears with simple infiltration of local anaesthetic (LA), or rather by neuromodulation. METHODS: Eighty-four patients were enrolled for this study and underwent an open release technique surgery. They were then asked for regular postoperative follow-ups. RESULTS: Thirty-two out of 84 patients (38%) developed pillar pain. Accordingly, injection of LA as pain treatment has since been studied and results compared with the conventional protocol for this painful syndrome. CONCLUSION: Even if the number of the patients considered is not great, there is evidence of a decrement of pillar pain by means of LA injections. Excellent functional outcomes and satisfaction were achieved using LA infiltrations for pillar pain after carpal tunnel decompression. The minimally invasive technique offers a quick, easy, effective, and inexpensive method useful to minimize and cure in a few days the pillar pain
Surgical treatment of Morton's neuroma: our experience and literature review
No full textOBJECTIVE: Morton's neuroma is a common foot problem associated with pain. MATERIALS AND METHODS: In 52 patients intermetatarsal spaces were operated on for Morton's neuralgia Gautier surgical treatment. The procedure included dorsal incision, division of the deep intermetatarsal ligament, and resection of the common digital nerve including the neuroma. Results. The outcome of the operation was excellent in 47 patients. CONCLUSIONS: The results show the efficacy of the surgical treatment of Morton's neuralgia with a dorsal incision, over a long follow-up perio
Dupuytren's Disease simulated by epithelioid sarcoma with atypical perineural invasion of the median nerve. Case report.
No full textEpithelioid sarcoma is an infrequent tumour, especially in upper limb, which nerve spread is not common. We describe the case of a 27 years old caucasian male with initial diagnosis of Dupuytren's disease. He underwent palmar fascia surgery, but the surgical treatment was followed by recurrence of the deformity in retraction of 4th and 5th finger of the left hand. When he presented himself at our attention, the patient underwent surgical biopsy and new histological examination was made with diagnosis of epithelioid sarcoma. We highlight essentially two aspects of this case: the diagnostic delay of tumour caused by simulation of the Dupuytren's disease and the atypical perineural spread along the median nerve
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
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
