The functional brace in the treatment of delayed union and non-union
No full textAfter years of experience in the treatment of fresh disphyseal fractures of the tibia and humerus using functional braces, we began to use them in cases of delayed union and pseudoarthrosis. This decision was encouraged by the excellent results obtained in fresh fractures and by the favourable effects of function on the repair process. The 15 cases reviewed, 13 in the tibia and 2 in the humerus, had previously been treated by various traditional methods. Treatment by functional bracing consisted of removing any plates or other devices, sometimes in association with 'minimal' surgery such as fibular osteotomy, prior to the application of the functional brace. Total weightbearing was allowed ab initio until there was complete radiographic healing. All the cases resulted in complete healing over a period ranging from two to five months, with total functional recovery of the limb involved

No full textPodoscopic examination was performed in 582
children (index subjects) aged 4 to 10 years,
and in 132 couples of parents and 114 siblings
of index subjects with flat or cavus foot or
normal foot. In the index subjects the overall
incidence of flat foot was 15 % with a greater
frequency in males; the incidence decreased
from 29 % to 14 % between 4 and 6 years and
then remained substantially stable. Two thirds
of the affected children had a flat foot of slight
or moderate severity; 39 °/o were obese. Overall,
a cavus foot was found in 16 % of the index
subjects, females being more frequently affected; the incidence of the deformity ranged
from 3 % at 4 years to about 20 % at 8-10
years. The frequency of flat foot was significantly higher in the parents (33%) and siblings (31 %) of the index subjects with flat
foot than in the parents (10%) and siblings
(11 %) of the index subjects with a normal
foot. No familiar predisposition to cavus foot
was observed
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
Impiego clinico della stimolazione elettrica in ortopedia e traumatologia
No full textLa scelta terapeutica del medico, nel trattamento di patologie dell’apparato muscolo-scheletrico, si fonda su una diagnosi appropriata e sulla scelta della terapia efficace per la patologia in cura. La terapia potrà essere attuata con un farmaco oppure con un dispositivo medico. La terapia con un dispositivo medico per la stimolazione elettrica dell’osteogenesi o della condroprotezione deve garantire:
la sicurezza elettrica del dispositivo;
la sicurezza biologica, intesa come assenza di effetti collaterali;
l’efficacia del dispositivo nella specifica patologia, dimostrata da studi clinici;
l’assenza di controindicazioni specifiche per il paziente che dovrà utilizzare il dispositivo medico.
La letteratura dimostra che l’efficacia terapeutica di un dispositivo medico è legata alle caratteristiche fisiche del segnale elettrico, magnetico o elettromagnetico generato dall’applicatore. Pertanto, l’impiego di un dispositivo deve fondarsi o su documentate esperienze cliniche condotte con il dispositivo stesso o su una chiara dimostrazione di equivalenza con dispositivi che erogano segnali efficaci. Attualmente è presente nel mercato italiano una pletora di dispositivi per “magnetoterapia” o “CEMP”, privi di documentazione clinica che ne documentino l’efficacia e la sicurezza biologica. Questi dispositivi sono proposti ai pazienti per le più svariate e ampie indicazioni: dalla pseudoartrosi alla cellulite. Non è facile se non impossibile per l’ortopedico reperire in letteratura le necessarie informazioni sulle caratteristiche dei diversi dispositivi di “magnetoterapia” o “CEMP”. Indicazioni, controindicazioni ed effetti collaterali sono contenuti unicamente nel manuale di istruzione, che rimanda alla responsabilità del medico l’uso del dispositivo, il quale, in assenza di adeguata documentazione clinica, potrebbe esporre il paziente ad un trattamento inefficace se non dannoso. Nella pratica clinica, la prescrizione all’uso della stimolazione elettrica si deve fondare su una corretta diagnosi e su una specifica indicazione all’uso del dispositivo più idoneo. In questo modo, il medico ottempera al suo dovere di proporre una terapia efficace e sicura
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
