The current study reports the case of a 15-year-old male who presented to The First Affiliated Hospital of Soochow University (Suzhou, Jiangsu, China) with a 3-day history of anergy and epistaxis. The patient was diagnosed with T-cell acute lymphoblastic leukemia according to the results of a bone marrow examination and received chemotherapy. During the agranulocytosis period, the patient developed pneumonia of the right upper lung (RUL). Once complete remission was achieved, the patient underwent a lobectomy of the RUL, together with amphotericin B therapy, following the confirmation of pulmonary mucormycosis by the histopathological results. The patient experienced 12 months of uneventful follow-up post-surgery. [ABSTRACT FROM AUTHOR]

To study the clinical application of dual-energy CT (DECT) in the knee ligaments. Twelve cases (24 knees) were scanned using dual-energy CT for the knee. Two- and three-dimensional images were used for display in all cases by means of multi-planar reformation (MPR) and volume rendering technique (VRT). All images were ranked by two radiologists according to the grade of knee ligament displayed, the definition of edge and attachment points of the knee ligament. The partial ligaments of 24 knees, such as the patellar ligament, fibular collateral ligament, anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) were clearly displayed; the tibial collateral ligament was not satisfactorily displayed. The transversal ligaments, such as lateral patellar retinaculum and medial patellar retinaculum, and the posterior ligament, such as oblique popliteal ligament could not be shown clearly. The dual-energy CT is a new and valuable tool to qualitatively display the main ligaments of the knee. [ABSTRACT FROM AUTHOR]

Patients with hepatocellular carcinoma (HCC) exhibit a high incidence of concomitant cirrhosis with leukopenia and/or thrombocytopenia. In the present study, perioperative changes in the white blood cell (WBC) and platelet (PLT) counts and associated complications were investigated to assess the safety of transcatheter arterial chemoembolization (TACE) for HCC patients with preprocedural leukopenia or thrombocytopenia. The records of 1,461 HCC patients who received TACE between January 2012 and December 2013 were retrospectively reviewed. The incidence of complications during the perioperative period and changes in the WBC and PLT counts were recorded. A Chi-squared test was used to evaluate the associations between postoperative infection and preprocedural WBC count and between bleeding at the puncture site and preprocedural PLT count. The WBC count of the majority of the patients increased within 3 days and returned to the preprocedural level within 30 days after TACE. The PLT count decreased within 3 days and returned to the preprocedural level within 30 days after TACE. The major complications were liver decompensation (n=66), puncture site bleeding (n=45), infection (n=33), severe thrombocytopenia (n=8), upper gastrointestinal bleeding (n=6), tumor bleeding (n=4) and agranulocytosis (n=3). A Chi-squared test revealed that postoperative infection was not associated with preprocedural WBC count and puncture site bleeding was not associated with decreased PLT count due to hypersplenism. Therefore, TACE was found to be safe for HCC patients with preprocedural thrombocytopenia or leukopenia due to hypersplenism, with a low incidence of major complications during the perioperative period.

We discuss the generation and evolution of a macroscopic entanglement light with a subthreshold non-degenerate parametric oscillator, coupled to a vacuum reservoir. The four-level atoms driven by two classical fields interact with the parametric oscillator. The master equation for the cavity modes of the scheme is derived and analyzed, the entanglement properties of the two-mode light generated by this scheme inside and outside the cavity is studied. We show that the light produced by this system is strongly entangled with time evolution inside and outside a cavity. [ABSTRACT FROM AUTHOR]
