Outcomes of acetabular fractures treated with acute fix and replace versus open reduction and internal fixation in elderly population: a multicentric retrospective study
Full text linkPurpose: The optimal operative treatment for displaced acetabular fractures in elderly population is still object of debate. Acute fix and replace procedure, the so called “combined hip procedure” (CHP), was introduced because of the poor results of the open reduction and internal fixation (ORIF) alone. The aim of the study is to compare clinical outcomes of CHP and ORIF alone for the treatment of acetabular fractures in elderly patients. Methods: This is the largest multicentric retrospective analytical study, with a case–control design on the issue. Hospital records and clinical notes were reviewed to collect demographic, peri-operative, and clinical data. Results: A total of 45 patients met the inclusion criteria: 24 patients entered the CHP group whereas 21 entered the ORIF control group. The mean age was 69.5 + − 1.12 years in the ORIF group and 73.4 + − 1.84 in the control group. The most frequent traumatic mechanism was the fall from same level in both groups (37.5% CHP; 42.9% ORIF). Operating time was significantly lower in the CHP group compared to the ORIF group (207 + − 11.0 ORIF; 175 + − 9.16 CHP; p < 0.05). Moreover, full weight-bearing was allowed significantly earlier in the CHP group compared to ORIF alone (37.3 + − 1.59 ORIF; 32.5 + − 1.69 CHP; p < 0.05). Among the clinician-completed scores, the HHS at three months was higher in the CHP group (66.3 + − 1.83 ORIF;73.6 + − 2.09 CHP; p < 0.05). All the other clinical outcomes were similar in both study groups. Conclusion: CHP is desirable treatment option in elderly patients with acetabular fracture when there are poor expected outcomes in terms of joint survival with ORIF alone

Epidemiology and aetiology of male and female sexual dysfunctions related to pelvic ring injuries: a systematic review
Full text linkIntroduction: Pelvic ring injuries, frequently caused by high energy trauma, are associated with high rates of morbidity and mortality (5–33%), often due to significant blood loss and disruption of the lumbosacral plexus, genitourinary system, and gastrointestinal system. The aim of the present study is to perform a systematic literature review on male and female sexual dysfunctions related to traumatic lesions of the pelvic ring. Methods: Scopus, Cochrane Library MEDLINE via PubMed, and Embase were searched using the keywords: “Pelvic fracture,” “Pelvic Ring Fracture,” “Pelvic Ring Trauma,” “Pelvic Ring injury,” “Sexual dysfunction,” “Erectile dysfunction,” “dyspareunia,” and their MeSH terms in any possible combination. The following questions were formulated according to the PICO (population (P), intervention (I), comparison (C), and outcome (O)) scheme: Do patients suffering from pelvic fracture (P) report worse clinical outcomes (C), in terms of sexual function (O), when urological injury occurs (I)? Is the sexual function (O) influenced by the type of fracture (I)? Results: After screening 268 articles by title and abstract, 77 were considered eligible for the full-text analysis. Finally 17 studies that met inclusion criteria were included in the review. Overall, 1364 patients (902 males and 462 females, M/F ratio: 1.9) suffering from pelvic fractures were collected. Discussion: Pelvic fractures represent challenging entities, often concomitant with systemic injuries and subsequent morbidity. Anatomical consideration, etiology, correlation between sexual dysfunction and genitourinary lesions, or pelvic fracture type were investigated. Conclusion: There are evidences in the literature that the gravity and frequency of SD are related with the pelvic ring fracture type. In fact, patients with APC, VS (according Young-Burgess), or C (according Tile) fracture pattern reported higher incidence and gravity of SD. Only a week association could be found between GUI and incidence and gravity of SD, and relationship between surgical treatment and SD. Electrophysiological tests should be routinely used in patient suffering from SD after pelvic ring injuries
Bone metastasis in hepatocellular carcinoma. A report of five cases and a review of the literature.
No full textHepatocarcinoma occurs frequently throughout the world. Bone metastases are rare although incidence has increased because of progress in diagnosis and treatment. The authors report 5 cases of bone metastases and review the literature. The spine is the most frequent localization of bone metastases. Radiotherapy is the treatment of choice for this lesion. Surgery should be used to prevent and treat complications such as nerve compression and pathologic fracture, only if the coagulative pattern and the conditions of the patient allow it. The authors recommend the use of long intramedullary nailing when localization of the disease is in the femur, with prophylactic stabilization of the neck in diaphyseal metastasis
Bone and maxillofacial abnormalities in thalassemia: a review of the literature.
No full textThalassemia is an inherited blood disorder due to an imbalanced globin chain synthesis leading to anaemia that requires regular blood transfusions and iron-chelating therapy. Of all organ failures secondary to iron deposit, and all the complications, heart failure still represents the first cause of death. Osteopenia and osteoporosis can be considered important causes of morbidity in a population whose lifespan is getting longer, with a strong impact on their quality of life. Authors have reported mainly bone, oral and maxillofacial abnormalities and relative complications, especially in terms of traumatic risk, in patients affected by thalassemia. As examples, this study reports bone modifications in three clinical cases; one of these was also complicated with a femoral fracture, surgically treated with the same criteria of metastatic femoral bone disease. More research on this topic is necessary for the prevention of several complications caused by this disease, and to carefully plan dental or traumatologic operations
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
