A 21-year-old female developed severe unremitting intravascular hemolysis following closure of a large patent ductus arteriosus using an Amplatzer duct occluder. Percutaneous deployment of fibered platinum coils within the nitinol wire cage of the Amplatzer duct occluder abolished the residual shunt through the device and resulted in cessation of(More)
The acute response of pig skin to treatment with high energy carbon ions (plateau region) at the Gesellschaft für Schwerionenforschung (GSI, Darmstadt, Germany) was compared with changes after 200 kV x-irradiation. Carbon doses isoeffective to the x-ray doses were computed with a recently established model for calculation of the biological effect of heavy(More)
Hepatitis B virus (HBV) testing and vaccination rates remain low among Asian-American/Pacific Islanders (APIs) despite high rates of HBV infection. The aim of our study was to assess the effectiveness of an outreach campaign to increase HBV knowledge, testing, and vaccination among a cohort of APIs. Vietnamese Americans were invited to participate in a free(More)

A variational principle has been derived for the propagation constant of a wave in a uniform lossless system or of the propagation constant of one of the spatial harmonics in a periodic lossless system containing an electron beam. The principle can be simplified somewhat when it is limited to longitudinal beams and Brillouin beams with zero curl of the(More)
1.  It has previously been demonstrated that metabolism of drugs via a single enzymatic pathway, particularly CYP3A4, is associated with increased risk for drug-drug interactions (DDI). Quantitative experimental systems as well as integrated prediction models to assess such risk during the preclinical phase are highly warranted. 2.  The present study was(More)
Thirty-three X-press cementless stems (Depuy) manufactured according to standardized X-rays were inserted from 1992 to 1994. The patients’ mean age was 49 (range 15–79) years with a mean follow-up of 32 (+/–6) months. A characteristic radiographic pattern of aseptic loosening with erosion of the medial cortex by the tip of the stem occurred in 28 patients(More)
In 2340 adult patients above the age of 26 years with rheumatic valvular disease (RHD) seen since 1987, injection benzathine penicillin (once in 3 weeks) was discontinued and the patients were followed for evidence of rheumatic fever for a period of one to nine years (mean of 3 years). Recurrence of rheumatic fever was seen in 5 patients (0.21%). This study(More)
