In this paper w e discuss three little known letters on the Konigsberg bridges problem. These letters indicate more clearly Euler’s attitude to the problem and to his solution of it.
BACKGROUND Mistreatment of trainees remains a frequently reported phenomenon in medical education. One barrier to creating an educational culture of respect and professionalism may be a lack of alignment in the perceptions of mistreatment among different learners. Through the use of clinical vignettes, our aim was to assess the perceptions of trainees toward themes of potential mistreatment at ...
Despite improvements in standard therapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone for patients with untreated, diffuse large B-cell lymphoma, up to 40% of these patients relapse. Lenalidomide alone or in combination with rituximab has been shown to be active in relapsed/refractory aggressive lymphomas. In this phase I study we determined the maximum tolerated do...
The significance and treatment of ventricular premature beats (VPBs) in patients without sustained ventricular tachycardia (VT), sudden death, or syncope remains unclear. We undertook a prospective study of programmed electrical stimulation (up to two extrastimuli and burst pacing) in 73 patients (age 60 +/- 10 years) with high-grade VPBs who had no evidence of sustained VT, sudden death, or sy...
There is no consensus on optimal screening for anal cancer (AC) in HIV+ women. Seven hundred fifteen unique asymptomatic women in a high-prevalence HIV+ community were screened for AC with anal cytology and triage to high-resolution anoscopy after routine screening was implemented in a large urban hospital system. Of these, 75 (10.5%) had an abnormal anal cytology and 29 (38.7%) of those with a...
Levels of clotting factors II, V, and VII were measured on admission and then daily in 12 patients with grade IV hepatic coma due to fulminant hepatic failure. Factor VII levels obtained within 36 hours of the development of grade IV coma were not of value in predicting which patients would subsequently recover consciousness. Four of the latter group had levels below 9% at this time while the l...
Non-small cell lung cancer (NSCLC) accounts for the majority of all lung cancers. A 69-year-old female with postoperatively recurrent NSCLC was treated weekly with nanoparticle-albumin-bound paclitaxel (nab-paclitaxel) monotherapy every 4 weeks as a tenth line chemotherapy, and stable disease was achieved by seven cycles of this regimen. The patient developed grade 4 neutropenia and grade 3 leu...
BACKGROUND Patients seropositive for cytomegalovirus (CMV) and undergoing allogeneic haemopoietic stem-cell transplantation (HCT) are at risk for CMV reactivation. Stimulating viral immunity by vaccination might achieve CMV viraemia control without the need for antiviral agents. CMVPepVax is a chimeric peptide composed of a cytotoxic CD8 T-cell epitope from CMV pp65 and a tetanus T-helper epito...
The natural history of gastric epithelial dysplasia and its relation to gastric cancer are ill defined. A consecutive series of 40 patients with an initial diagnosis of gastric epithelial dysplasia based on examination of endoscopic biopsies has been reviewed to determine the clinical outcome and to evaluate a two tier histological grading system as a predictor of the risk of cancer. On review,...
