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
Myositis ossificans in children: description of a clinical case with a rare localization
No full textMyositis ossificans (MO) also defined as myosteosis or hematoma ossificans, is a benign condition presenting as an heterotopic, well-defined neoformation in muscles and soft tissues. It was first described by Guy Patyn in 1692 and defined in its histopathological aspects by Von Dusch in 1868. It most frequently has a posttraumatic onset (60-75% of cases), usually following small repeated traumas or a single bruising episode. MO is rare in subjects under 10 years of age, whereas it is more frequent in teen-age athletes, and over 50% of cases are dignosed in the third decade of life. Its etiopathogenesis in unknown, although it is associated with a traumatic event in 75% of cases. MO most common localizations are arms, legs, shoulders and hands, rarely chest. The lesion presents with different degrees of maturation and diagnostic tools are echotomography (ECT) as a primary investigation, and NMR for a better diagnostic assessment. Because of the self-limiting nature of the lesion and its spontaneous resolution, a conservative treatment is advised along with radiological follow-up which is most indicated in the presence of either typical MO features or highly suggestive ECT o NMR findings. In case of uncertain diagnosis, relevant muscular function impairment, considerable lesion dimension or severe pain, exeresis and histological examinations are suggested. The present paper describes and discusses a clinical case of MO in a child, with a rare localization
Clinical, mammographic and ultrasonographic features of blunt breast trauma
No full textEvaluation of acute breast injury depends largely on the findings at physical examination. Patients may not initially remember the traumatic
event to the breast, and mammography may be the first radiographic study to suggest this history, particularly if it shows findings of fat necrosis.
Clinical, mammographic and sonographic findings resulting from non-iatrogenic trauma to the breast can be mistaken for signs of malignancy,
especially because trauma often is not considered as a cause for such findings.
In this paper some of the manifestations of blunt traumatic injury to the breast are presented.
Familiarity with mammographic and sonographic findings of breast trauma is essential for the radiologist to avoid unnecessary biopsy and to
avoid overlooking breast cancer

No full textA case of hypersensitivity pneumonitis in a worker exposed to terephthalic acid in the production of polyethylene terephthalate
Full text linkOccupational hypersensitivity pneumonitis (OHP) is an interstitial lung disease caused by sensitization to an inhaled antigen. Polyethylene terephthalate (PET) is mainly used for disposable beverage bottles. A clinical case of hypersensitivity pneumonitis (HP) in a 66-year-old patient in the follow-up as a worker formerly exposed to asbestos is presented. At the first visit in 2012 a diagnosis of asbestosis and pleural plaques was formulated. In 2017 the high resolution computed tomography was performed demonstrating a slight progression of the pulmonary fibrosis, while physical examinations revealed inspiratory crackles on auscultation, and lung function tests showed a decreased diffusing capacity for carbon monoxide. The radiological and histological pictures were compatible with HP. From 1992 to 2013 the patient worked in a chemical company that produced PET for disposable beverage bottles. A diagnosis of OHP was made, and the most likely causative agents were terephthalic acid and dimethyl terephthalate. To the best of the authors' knowledge, this is the first report of an OHP case in PET production. Int J Occup Med Environ Health. 2020;33(1):119-23.
