No full textIMPACT OF 3D PRINTING ON THE SURGICAL MANAGEMENT OF TRACHEAL STENOSIS ASSOCIATED TO PULMONARY SLING: A CASE REPORT.
No full textCongenital tracheal stenosis (CTS) is rare lesions frequently associated with pulmonary sling (PS). Despite the recent improvement in the results by the introduction of slide tracheoplasty (ST) and multidisciplinary approach, surgical management remains difficult and several authors, for this reason, debate for a conservative approach in these cases. Preoperative planning, require hence the use of the most innovative technology to gain the best possible result. This report describes a complicated, unsuccessful surgically treated case of CTS associated to PS. Based on this result and in order to improve the outcomes, we have built a 3D model of patient's trachea simulating preoperative surgical planning. We have hypnotized that having the model preoperatively the choice of surgical technique would have been different. Since that case, 3D models are introduced in our practice and built before tracheal or cardiac cases considered to have complex anatomy. Future investigations are required but at the moment this experience confirms the utility of 3D model in the evaluation of children considered for tracheal surgery
Temporary epicardial pacing in an extremely low-birth-weight infant with congenital atrioventricular block
No full textCongenital atrioventricular block is a rare, but severe occurrence in the newborn can be related to various cardiac malformations or to maternal autoimmune diseases, particularly systemic lupus erythematosus. We report an extremely low-birth-weight infant affected by congenital heart block, due to positive anti-RO/SSA and anti-LA/SSB antibodies of the mother, with progressively increasing respiratory distress syndrome and heart failure. The infant was successfully treated with an external constant-current, single-chamber ventricular (VVI) temporary epicardial pacing, placed on the second day of life, at the weight of 810 g. After this treatment, cardiac failure resolved and respiratory assistance could be rapidly stopped. A single-chamber, rate-responsive, permanent pacemaker was placed at 3 months of life with steroid-eluting, epicardial-pacing leads. We emphasize that early extrathoracic temporary epicardial pacing is able to resolve heart failure in an extremely low-birth-weight infant. © 2007 The Authors; Journal compilation © 2007 Blackwell Publishing, Inc
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
SUPRA-ANNULAR MITRAL VALVE IMPLANTATION IN VERY SMALL CHILDREN
No full textObjective Mitral valve replacement (MVR) is a surgical option when mitral valvuloplasty is not feasible/successful. This study reviews our experience with MVR in very young children. Methods From July 2004 to January 2014, seven children (mean age 13.3-±-11.2 months; range 4 months to 35 months; mean body weight 6.0-±-2.2-kg) underwent MVR with a mechanical prosthesis in the supra-annular position. To provide better exposure in the left atrium, we performed in all but one case a biatrial transeptal incision according to Guiraudon. Six patients had congenital defects of the mitral valve and one had rheumatic. Six patients had undergone previous cardiosurgical procedures. Results All patients were implanted with a CarboMedics (CarboMedics, Austin, TX, USA) mechanical prosthesis. Mean prosthesis size was 19.0-±-3.1-mm (range 16 to 25). There were no cases of operative or late mortality. At follow-up (mean 67.1-±-34.8 months; range 25 to 108 months) two patients (28.6%) required reoperation both for thrombotic pannus formation over the disc at two and three months from first operation, respectively; only in one case was replacement necessary. Conclusion Supra-annular MVR may be considered a feasible secondary surgical option in children with a small annulus when mitral valvuloplasty is unsuccessful or unsuitable. Early and mid-term outcomes are acceptable but complications are not uncommon, especially related to thrombotic events
