External longitudinal titanium support for the repair of complex pectus excavatum in adults
No full textSeveral techniques exist for the repair of complex pectus excavatum. The placement of retrosternal metal bars improves the results by reducing the recurrence rate, but entails several possible risks, complications and disadvantages. A new method, specifically conceived for the repair of severe, asymmetric forms in adult patients, is reported. The corrected bone is fixed in the proper position by two, patient-customized, titanium struts, externally screwed to the manubrium and sternal body. Any retrosternal bar is thus avoided, reducing possible complications, without hampering the chest wall dynamic. In this particularly difficult issue, this technique provides long-term good functional, mechanical and cosmetic results and does not entail a second surgery for struts removal
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
the acute stress reaction to major thoracic surgery
No full textThe aim of this revue is to examine the current literature on the physio-pathological mechanism liable for the inflammatory reaction after major surgical injury and the nature
and development of the related morbidity. We describe the endocrine and metabolicchanges that occur as consequences of major thoracic surgery and the clinical implications of these reactions. The understanding of the stress response mechanism and the early detection
of it’s clinical manifestations will aid in recognizing and probably help in correcting
deviations from the norm

No full textDiagnosis and endovascular treatment of an internal mammary artery injury
Full text linkInternal mammary artery (IMA) disruption after blunt chest trauma is rare. In some instances, it may occur after
mild chest trauma with minor external physical findings. However, prompt diagnosis and treatment are necessary,
as it can be associated with vascular and parenchymal injuries.
We report a case of blunt chest trauma resulting in a sternal fracture associated with an IMA injury, active
anterior mediastinal bleeding, bilateral lung contusions, and a left hemothorax. It was successfully treated by selective
embolization to the left IMA branch and chest tube placement
