Modalities and Effects of Left Ventricle Unloading on Extracorporeal Life support: a Review of the Current Literature.

Introduction/aim: Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) support is increasingly used in refractory cardiogenic shock and cardiac arrest, but is characterized by a rise in afterload of the left ventricle (LV) which may ultimately either further impair or delay cardiac contractility improvement. The aim of this study was to provide a comprehensive overview regarding the different LV venting techniques and results currently available in the literature.

Methods: A systematic literature search was performed in the PubMed database: 207 articles published between 1993 and 2016 were included.

Familial chromosomal translocation X; 22 associated with infertility and recurrent X mosaicism.

Background: Individuals with apparently balanced translocations, often, show no clinical findings. However, in meiosis, translocations tend to cause errors on chromosome disjunction and the ones involving sex chromosomes have particular implications for the phenotype. Male carriers of balanced X-autosome translocations are almost invariably infertile due to interruption of the spermatogenesis, but the mechanism is not fully understood.

Simplified upper pole nephrectomy: initial experience.

Objective: To assess the results of an upper pole nephrectomy technique on 5 children.

Materials And Methods: Upper pole nephrectomy was performed on 5 children, including 4 females and 1 male. Age ranged from 3 to 6 years old.
