Five patients with Paget's disease involving the patella were evaluated for the following radiographic features: trabecular pattern, cortical integrity, density, and size of the affected patella. Radiographic appearances consisted of minimal trabecular coarsening in the patella of nearly normal size and progressed to considerable cortical thickening and osteoblastic remodeling in a dramatically enlarged patella. The radiologic features of Paget's disease of the patella are distinctive and should obviate biopsy.The opinions and assertions contained herein are the private views of the authors and do not reflect the views of the Department of the Army or of the Department of Defense 相似文献

Emerging infectious diseases are some of modern society’s greatest threats. Like some great construction efforts designed to protect mankind, current public health measures against these emerging pathogens have not always been successful. This paper highlights the importance of embracing new interdisciplinary approaches towards emerging pathogen threats. One such approach, termed One Health, is quickly being embraced by professional organizations and public health institutions across the world as a way forward. This paper briefly discusses the above problems and preliminary steps taken by Chinese academic institutions to embrace the One Health approach. 相似文献

Donation-related data for 1488 allogeneic peripheral blood stem cell (PBSC) transplants reported to the International Bone Marrow Transplant Registry (IBMTR) or the European Blood and Marrow Transplant Group (EBMT) by 152 teams worldwide between 1994 and 1998 were reviewed. In 1998, 26% of allografts registered with the IBMTR were collected from blood. Median age of PBSC donors was 38 years (range <1-76), and 55% were male. Of 1486 donor-recipient pairs evaluable for HLA compatibility, 1322 (89%) were HLA-identical siblings. Recombinant human granulocyte colony-stimulating factor (G-CSF) was employed to mobilize PBSCs in almost all (99%) cases. One hundred and seventy (20%) of 828 evaluable PBSC donors had a central catheter placed for leukapheresis. Eighty-five percent of 1321 evaluable PBSC grafts were collected with one or two leukaphereses. There were 15 reported donation-related adverse events (1% of evaluable donors). Complications were catheter-related in five. No donation-related fatalities were reported. These data suggest that PBSC donation is becoming more prevalent worldwide. It appears to have a safety profile comparable to marrow harvesting, although experience with the latter is much more extensive. 相似文献

Hyperpolarization-activated cyclic-nucleotide-gated (HCN) channels in the heart modulate cardiac automaticity via the hyperpolarization-activated cation current ( named Ⅰf, Ⅰh, or Ⅰq). Recent studies have unveiled the molecular identity of HCN (HCN1-4) channels. HCN isoforms are unevenly expressed in the heart, even in the sinoatrial node. Features of HCN currents have been characterized in cardiac and other types of cells or in cell lines transfected with the HCN isoforms. The factors modulating Ih and the physiological significance of HCN channels in the heart have been extensively investigated in recent years. The hypothesis for transplanting and/or creating biological pacemakers to replace diseased sinoatrial and/or atrioventricular nodes has been postulated and tested in animal models. Local overexpression of HCN2 channels in the left atrium or in the left conductive bundle branch of the left ventricle via gene delivery induced significant Ⅰh and escape rhythms during vagal stimulation in canines. In addition, implantation of human mesenchymal stem cells with overexpression of HCN2 channels to the canine left ventricular wall was associated with formation of spontaneous escape rhythms of left-sided origin during vagal-stimulation-induced sinus arrest. This preliminary data suggest that the use of HCN channels may hold great promise in,the development of biological pacemakers. 相似文献

To determine attitudes regarding attending rounds, the authors surveyed all internal medicine residents and attending physicians
at the eight Army teaching hospitals. The response rate was 86%, including 166 (76%) of 217 residents and 246 (93%) of 264
attendings. Of 12 educational activities, attending rounds were randked seventh by residents in their perceived value. Both
residents and attendings favored sessions that lasted 90 minutes or less and were held three to four times per week. Most
respondents felt case presentations should take 5 minutes or less and be delivered away from the patient’s bedside. On average,
residents preferred less time at the bedside than did attendings (25% vs. 34% of attending round time). Residents desired
substantial control of the agenda for rounds and also wanted to be responsible for one-third of the teaching. The attending-physician
attributes that residents valued most highly were fund of knowledge, availability, and relating well to housestaff. Since
residents’ and attending physicians’ attitudes may differ, expectations regarding attending rounds should be clarified at
the beginning of a ward rotation so that mutually acceptable goals can be established.
