No full textBackground. An intraneural ganglion cyst is a non-neoplastic gelatinous cyst, which can be found within the epineurium of a peripheral nerve and lead to signs and symptoms of peripheral neuropathy. Early diagnosis and appropriate surgical treatment of this condition is a key to a successful outcome. Materials and methods. We describe a case of a patient with peroneal nerve neuropathy caused by an intraneural ganglion cyst. Postsurgically, only partial relieve of the symptoms was achieved because of delayed diagnosis. Results and conclusions. The aetiology of intraneural ganglia is controversial and historically different pathogeneses of this condition have been described. Diagnosis of these cysts is based on MRI. Multiple surgical treatment strategies have been developed based on different pathogenesis of the formation of these cysts, but neuropathy is reversible only, if this condition is diagnosed and treated early
Krūtinės angos sindromas: literatūros apžvalga ir klinikinis atvejis
Full text linkThoracic outlet syndrome (TOS) is a clinical entity comprising a constellation of symptoms resulting from compression of the neurovascular bundle in the thoracic outlet. Vascular, neurological, and neurovascular types of TOS are distinguished according to the structures affected. The most common form of TOS is neurological, occurring in up to 95% of cases. TOS is a common neurological disease with a wide range of symptoms. It is still little known to medical professionals and is often undiagnosed or diagnosed late.
This study provides a literature review of the symptomatology and treatment methods for TOS, highlighting certain symptoms not previously documented in the literature and presenting an illustrative clinical case. A 67-year-old female reported left arm pain following a muscle biopsy conducted for suspected polymyositis. The pain radiated to the inner arm, shoulder blade, and distal parts of the arm. The patient had been experiencing chronic facial and head pain, as well as nausea, for 35 years. Examination revealed arm weakness and positive thoracic outlet syndrome (TOS) provocation tests. Brachial plexus decompression were performed, resulting in an excellent treatment outcome.
This case highlights the complexity of TOS presentations and the importance of considering TOS in differential diagnoses.Krūtinės angos sindromas (KAS) apima visumą simptomų, kylančių dėl neurovaskulinio pluošto kompresijos krūtinės angoje. Išskiriami kraujagyslinio, neurologinio ir neurovaskulinio KAS tipai [1]. Neurologinis KAS (nKAS) laikomas dažniausiu ir, kaip nurodoma kai kuriuose mokslo darbuose, pasireiškia iki 95 proc. atvejų. nKAS gali pasireikšti galvos, viršutinės galūnės, kardiologiniais ar kojų simptomais. Medicinos darbuotojams KAS dar mažai žinoma liga, dažnai neįtariama, diagnozuojama klaidingai arba vėlai.
Šiame darbe sistemingai apžvelgiama ligos simptomatika ir gydymo metodai, pateikiami kai kurie mokslinėje literatūroje neminimi simptomai, aptariamas iliustratyvus klinikinis atvejis. 67 m. moteris skundėsi kairės rankos skausmu, kilusiu atlikus raumens biopsiją dėl įtarto polimiozito. Skausmas plito į žasto vidinę pusę, mentę, žemesnes rankos dalis. Pacientę 35-erius metus kankino veido ir galvos skausmai, pykinimas. Nustatytas rankos silpnumas ir teigiami KAS provokaciniai testai. Pacientei atlikta petinio rezginio dekompresija, pasiekta puikių gydymo rezultatų
Kamptodaktilija: literatūros apžvalga ir klinikinis atvejis
Full text linkCamptodactyly is a congenital hand deformity characterized by a fixed flexion contracture, most commonly affecting the fifth finger. This literature review and case report highlight the clinical manifestations, and treatment options for camptodactyly. Occurring in approximately 1% of the population, the condition may be unilateral or bilateral and varies widely in severity [1–3]. Camptodactyly often appears at birth or during puberty, linked to genetic mutations, usually sporadic or autosomal dominant in nature [4, 5] painless, non-neurogenic flexion deformity at the proximal interphalangeal joint of the little finger, which may occur in isolation or in various developmental dysmorphology syndromes. In a ten-year survey of almost 10,000 consecutive neurology outpatient referrals, using a passive case finding strategy, camptodactyly was observed with a frequency of 0.43%. All were cases of isolated camptodactyly, and all but one were asymptomatic. Camptodactyly was more often bilateral, often asymmetric, than unilateral. A family history was common, sometimes with intrafamilial heterogeneity (symmetry, degree of angulation. Treatment remains controversial, with non-surgical options preferred for mild cases. Surgical intervention is considered when functionality is impaired. In this case, a patient with bilateral fifth finger contractures since birth managed the condition without surgery [3, 6]. This report aims to illustrate current understanding of camptodactyly’s natural course and discusses therapeutic strategies for better clinical outcomes.Kamptodaktilija – įgimta rankos deformacija, pasireiškianti fiksuota lenkiamąja kontraktūra, dažniausiai paveikianti penktąjį pirštą. Šioje literatūros apžvalgoje ir klinikinio atvejo aprašyme nagrinėjamas kamptodaktilijos klinikinis pasireiškimas ir gydymo galimybės. Liga pasireiškia 1 proc. populiacijos, gali būti vienpusė ar abipusė [1–3]. Kamptodaktilija dažniausiai nustatoma gimus arba paauglystėje.

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
