2005 PRETEXT: a revised staging system for primary malignant liver tumours of childhood developed by the SIOPEL group
Over the last 15Â years, various oncology groups throughout the world have used the PRETEXT system for staging malignant primary liver tumours of childhood. This paper, written by members of the radiology and surgery committees of the International Childhood Liver Tumor Strategy Group (SIOPEL), presents various clarifications and revisions to the original PRETEXT system
All-sky Medium Energy Gamma-ray Observatory: Exploring the Extreme Multimessenger Universe
The All-sky Medium Energy Gamma-ray Observatory (AMEGO) is a probe class
mission concept that will provide essential contributions to multimessenger
astrophysics in the late 2020s and beyond. AMEGO combines high sensitivity in
the 200 keV to 10 GeV energy range with a wide field of view, good spectral
resolution, and polarization sensitivity. Therefore, AMEGO is key in the study
of multimessenger astrophysical objects that have unique signatures in the
gamma-ray regime, such as neutron star mergers, supernovae, and flaring active
galactic nuclei. The order-of-magnitude improvement compared to previous MeV
missions also enables discoveries of a wide range of phenomena whose energy
output peaks in the relatively unexplored medium-energy gamma-ray band
Good Samaritan liver donor in pediatric transplantation.
We report a case of anonymous liver transplantation from adult to child
Historical review and perspectives in pediatric transplantation
Purpose of review
Recent progress in organ transplantation in children is illustrated by analysis of the most informative papers published during 2005-2006.
Recent findings
The review focuses on immunosuppression, steroid withdrawal or avoidance, living-related transplantation, long-term survival, drug-related nephrotoxicity, growth, and quality of life in solid organ transplantation.
Summary
Research on better, more selective, and safer immunosuppression must be pursued as well as the search for surrogate markers of tolerance. Long-term analysis is needed of quality of life beyond 10 - 15 years after transplantation
