No full textThe use of oxygen ozone therapy in the treatment of cervicobrachial pain: case series study
No full textThis retrospective, observational, uncontrolled case series study was carried out to evaluate the clinical efficacy and safety of intramuscular paravertebral injections of an oxygen-ozone (O2-O3) mixture in patients with cervicobrachial pain. One hundred and sixty-eight subjects affected by cervicobrachial pain, referred to Ozone Therapy Unit at San Pietro Fatebenefratelli Hospital in Rome (Italy), were enrolled in the study. All the subjects (n=168, 106 females and 62 males) completed the treatment and the follow-up visits. Subjects received 12 cervical intramuscular injections of an O2-O3 mixture (5 mL) with an O3 concentration of 16 μg/mL once a week. The overall reduction of pain was measured by the change in mean of Visual Analogue Scale (VAS) score from baseline to the end of treatment and from baseline to one, two, three, four and five years of follow-up. Patient satisfaction was assessed at the end of treatment, by modified MacNab Questionnaire. Possible adverse events related to the treatment were recorded. The mean (± standard deviation) VAS pain score at baseline, at the end of treatment, and during the follow-up at one, two, three, four and five years were 7.82 (±1), 1.6 (±1.5), 1.5 (±1.4), 1.4 (±1.3), 1.6 (±1.2), 1.5 (±1.3) and 1.60 (±1.2), respectively, showing a significant reduction in pain over time (p<0.001). Of 156 patients who responded to treatment, 128 (82.05%) were pain free at one year, 110 (70.51%) at second year, 103 (66.02%) at third year, 94 (60.25%) at fourth year and 86 (55.12%) at fifth year follow-up visit. According to pain distribution all subjects showed a significant reduction in pain over time in each group (p<0.05). No significant differences were observed between groups. No serious adverse events were observed during the entire study. We suggest the use of intramuscular paravertebral injections of an oxygen-ozone (O2-O3) mixture in patients with cervicobrachial pain as an effective and safe treatment option to consider before surgical intervention
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
Glenoid version: the role of genetic and environmental factors on its variability. An MRI study on asymptomatic elderly twins
No full textBACKGROUND: Glenoid version is the most variable parameter of the shoulder joint. No authors investigated if intrinsic genetic factors or influences from extrinsic sources are responsible for its variability. AIM: We compared glenoid version between elderly monozygotic and dizygotic twins intending to separate the contributions of genetics from shared and unique environments. METHODS: Glenoid version of the dominant shoulder was assessed by MRI using Friedman’s method in 30 pairs of elderly twins (16 monozygotic–14 dizygotic; mean age ± SD: 63.72 ± 3.37, 53–72). Heritability was estimated as twice the difference between the intraclass correlation coefficients for monozygotic and dizygotic pairs. The influence of shared environment was calculated as the difference between monozygotic correlation coefficient and the heritability index. According to job category, one way analysis of variance was used to estimate the differences between groups in the total sample and within zygosity groups. RESULTS: Glenoid version angle in monozygotic and dizygotic twins was −2° (SD: 2°) and −3° (SD: 3°), respectively (p = 0.334). Heritability index was 0.98, while the contributions of shared and unique environment were 0 and 0.02, respectively. According to working classes, no significant differences were found between the groups (p = 0.732, F = 0.31). CONCLUSIONS: Glenoid version is mainly genetically determined and only marginally influenced by environments. Level of evidence: III
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
Adhesive capsulitis of the shoulder: pain intensity and distribution
Full text linkPurpose
Papers regarding adhesive capsulitis (AC) of the shoulder focused on etiology, epidemiology, diagnosis, and treatment; until now, information on shoulder pain characteristics is still scarce. Our aim was to analyze pain intensity and distribution in patients with AC.
Methods
The study group was composed of 278 (133M–145F) consecutive patients with AC. After diagnosis, shoulder pain distribution was assessed through an upper limb pain map and pain intensity through a visual analog scale. Patients were distinguished on the basis of gender, age, time elapsed from onset of symptoms, and severity of functional limitation. Data were submitted to statistical analysis.
Results
Intensity of shoulder pain caused by AC was higher in females (p 0.05).
Conclusion
Shoulder pain due to AC may be influenced by gender and severity of functional limitation. AC pain distribution principally involves anterior aspect of the shoulder with downward extension of the arm until its distal third
