Jump performance during a season in elite volleyball players.

Background: The aim of this study was to measure and compare jump load and dynamic performance in elite volleyball athletes under varied conditions over an entire season of practices and games. Jump load and dynamic performance were compared among best jump height, mean jump height, as well as according to the number of jumps per game or practice session and the proportion of jumps higher than 50 cm relative to the total number of jumps in a practice or game.

Methods: Every jump performed by each of 12 players, in all practices and regular games (813 player-sessions in total), was measured by a particle accelerometer in accordance with a validated protocol (Vert, Fort Lauderdale, FL, USA).

The impact of a standardized perioperative management on hospital mortality after the Norwood procedure in a low volume center: results and perspectives.

Background: Mortality of newborns with Hypoplastic Left Heart Syndrome (HLHS) is mainly concentrated after Norwood procedure (NP) stage 1 palliation (S1P) and between S1P and stage 2 palliation (S2P). Standardized management of these patients may help to control hospital mortality. Aim of the study was to evaluate the impact on hospital mortality of a standardized perioperative management (SPM) for newborns requiring S1P in a low volume center for NP.

Use of a biodegradable, oversized stent in a child with tracheomalacia secondary to vascular external compression.

We describe the implantation of an absorbable, custom-made stent of polydioxanone to treat tracheomalacia in a 5-month-old patient with extrinsic compression by a double aortic arch. The use of an absorbable, oversized stent treated the tracheal collapse caused by vascular compression, avoided removal procedures, and allowed the infant's growth. The use of an oversized stent prevented stent migration and gave minimal problems of granulation.

Coronary Artery Involvement of Williams Syndrome in Infants and Surgical Revascularization Strategy.

Williams syndrome (WS) is a genetic disorder due to deficiency of elastin gene expression. It is characterized by typical somatic abnormalities and a wide range of cardiovascular malformations. Coronary artery involvement is a frequent finding of the syndrome, particularly in those patients with severe supravalvular aortic stenosis.

The successful management of a Bronchoesophageal fistula after lung transplantation: a case report.

We describe an unprecedented, disastrous complication after bilateral lung transplantation (BLT), a bilateral bronchial dehiscence with a right bronchoesophageal fistula leading to life-threatening septic shock. We also report the successful endoscopic management of this complication by double stenting and stress the efficacy of the multidisciplinary approach to this critical case.
