Search for Fingerprints of Tetrahedral Symmetry in
Theoretical predictions suggest the presence of tetrahedral symmetry as an
explanation for the vanishing intra-band E2-transitions at the bottom of the
odd-spin negative parity band in . The present study reports on
experiment performed to address this phenomenon. It allowed to determine the
intra-band E2 transitions and branching ratios B(E2)/B(E1) of two of the
negative-parity bands in .Comment: presented by Q.T. Doan at XLII Zakopane School of Physics: Breaking

Post-operative Aspergillus mediastinitis in a man who was immunocompetent: a case report
<p>Abstract</p> <p>Introduction</p> <p><it>Aspergillus </it>spp. infections mainly affect patients who are immunocompromised, and are extremely rare in immunocompetent individuals.</p> <p>Case presentation</p> <p><it>Aspergillus </it>post-operative mediastinitis is considered to be a devastating infection, usually affecting patients undergoing cardiothoracic surgery with specific predisposing factors. We describe the case of an immunocompetent 68-year-old Caucasian man with severe chronic thromboembolic pulmonary hypertension, who underwent pulmonary thromboendarterectomy and developed post-operative mediastinitis due to <it>Aspergillus flavus</it>. The environmental control did not reveal the source of <it>A. flavus </it>infection and, despite combined antifungal therapy, our patient died as a result of septic shock and multiple organ failure.</p> <p>Conclusion</p> <p><it>Aspergillus </it>mediastinitis mainly affects patients after cardiosurgery operations with predisposing factors, and it is unusual in patients who are immunocompetent. The identification of the <it>Aspergillus </it>spp. source is often difficult, and there are no guidelines for the administration of pre-emptive therapy in this population of at-risk patients.</p
