CORRELAZIONE TRA LUNGHEZZA MUSCOLARE E LESIONE MIO TENDINEA DEI MUSCOLI ISCHIO CRURALI NELLO SPORTIVO
Hamstrings lesions are common sport injuries and are the most frequent cause of sport arrest in professional athletes for an average time of more than 8 days. The recurrence rate is around 33% in the first 2 weeks after.
Hamstrings lesions develop commonly in terminal swing under eccentric contraction.
Muscular imbalance, lack of elasticity and flexibility have been considerated related to the risk of lesion.
The role of stretching in the prevention of the risk of muscular lesion have been studied in terms of correlation of Range of Motion and frequency of muscular lesion of hamstrings.
In this retrospective study the correlations between muscular lesion of hamstrings and muscular length have been studied to evaluate the presence of any correlation in a population of 20 athletes of an average age of 28,5 years.
Clinical measures have been done by goniometry of knee ROM and muscular length have been evalued sonographically. All measures have been compared with a control healthy population of athletes.
The results of the study showed a significative correlation between ROM and muscular length and a possible role of sonography in the identification of subjects at risk for lesion in case of insufficient muscular length
D.D.S.H. : developmental displasia of the spastic hip : strategies of management in cerebral palsy : a new suggestive algoritm
Hip problems in cerebral palsy are relatively frequent (25-75%). Subluxation and dislocation of the hip is proportional to the neuromuscular involvement and is often due to alteration caused by spastic muscle forces acting on the femoral head in the acetabular cavity. The EMMA approach (Early Multilevel Minimally-invasive Approach) has been designed to restore muscle balance, decrease hip migration and prevent bone deformities thereby avoiding future pain with minimal biological cost to the patient. EMMA is suitable for most patients, especially those with increased tone, poor muscle control and selectivity, Reimer Index (R.I.) 20%. We consider age and R.I crucial prerequisites for treatment steps. EMMA 1) age 2-4 years, RI 20%: multilevel injection of botulinum toxin in case of muscular hyperactivity without morphological alterations of the couple muscle-tendon (contractures). EMMA 2) age 4-6, RI 20%: multilevel aponeurectomies in case of muscular hyperactivity with morphological alterations of the couple muscle-tendon (retraction). EMMA 3) early bone surgery (growth plates). This approach has been adopted in the last 4 years to prevent bone deformities and give early mobilisation and early control of the pain. EMMA is simple to apply even in infants, both for hip containment and to decrease spasticity

Slipped Upper Femoral Epiphysis (SUFE): to do or not to do in sufe
Slipped upper femoral epiphysis (SUFE) is not an uncommon hip disease in adolescence. Usually, diagnosis of SUFE is delayed, has high risk of sequela and poor long-term results. This paper reviews the literature with a focus on epidemiology, aetiology, diagnosis, treatment and results regarding SUFE
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Ultrasound evaluation of the hips and histological correlations in Ellis van Creveld Syndrome : a case report
Ellis van Creveld Syndrome (EVCs) is a chondroectodermal dysplasia. Its clinical picture includes a meso-acromielic limb dwarfism with normal spine, involvement of the teeth, hair and nails, polydactyly of the hands and feet and heart malformations. Ultrasonography compared with histology were used in the present study to evaluate neonatal ultrasonographic hip development and acetabular hysto-morphology in EVCs. A flat and abnormal acetabulum with small beta angles and non measurable alfa angles were detected at repeated ultrasonographic evaluations at birth and at four months, with irregular echoes spiking from the inner part of the sockets; the acetabular cavities contained large early ossified proximal femoral epiphyses. Histology was obtained from phalangeal growth plates of a surgically removed extradigit, stained with alcian blue/PAS and E.E.. The growth plates showed a distorted anatomy with irregular column formation and abnormal distribution of the hypetrophic cells. Ultrasound morphology corresponded to the altered growth plates seen at histology. Early detection of an abnormally early developed proximal femoral ossification centre could be considered a diagnostic feature of the syndrome especially when present in the prenatal period
Variations on the Author
“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
We 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
