The clinical experience with cardiac myxomas and "myxoid imitators" at the Humana Heart Institute International is reviewed and contrasted with a comprehensive review of the world literature. Twenty-two patients with primary cardiac tumors have been treated at our institution. Three (13.6%) of them had myxoid imitators, and 19 had classic myxomas. One of the 19 patients with a classic myxoma had recurrence on two occasions (recurrence rate, 5.3%). The cases of 57 patients from the world literature are reviewed. Recurrence and/or metastases (including formation of mycotic aneurysm) occurred in approximately 50% of these patients. The overall mortality in these patients was 47%. This review provides documentation of the malignant clinical behavior of cardiac myxomas and myxoid imitators. Neither local recurrence nor regrowth of the tumor in a new location, whether intracardiac or extracardiac, can be predicted from the microscopic appearance of the primary tumor. Resection of the myxoma with a wide margin is the recommended surgical procedure but does not ensure a cure. Therefore, long-term follow-up is mandatory. 相似文献

We describe a case of a 54-year-old woman who had a right cardiac mass found on coronary angiography. Echocardiography, computed tomography, and cardiac magnetic resonance imaging characterized it as a thrombosed giant right coronary artery aneurysm. This was confirmed on pathology. We present the role of multimodality cardiovascular imaging in the diagnosis and characterization of a giant coronary artery aneurysm. 相似文献

AbstractPurpose: Evaluating the long-term impact of faculty development programs (FDPs) can help monitor the effectiveness of the program and identify areas for development. This study examined long-term differences in confidence, knowledge, behaviors, and policies of faculty members who attended FDPs on multiple choice question (MCQ) item analysis and faculty members who did not attend the FDPs.Methods: A cross-sectional study design was used, by administering a 24-item survey to a representative sample (simple random selection) of 61 faculty members at King Abdulaziz University Faculty of Medicine.Results: Among respondents, 34% did not attend FDPs; 53% attended 1–3 FDPs; and 13% attended more than 3 FDPs on MCQ item analysis. Results showed that faculty knowledge on elements of MCQ item analysis was significantly greater (p?=?.01) for members who attended the FDPs. Faculty who attended FDPs on MCQ item analysis were twice more likely to conduct item analysis in general (p?=?.020) and four times more likely to conduct item analysis for more than 70% of module examinations (p?=?.005).Conclusion: FDPs focused on MCQ item analysis can yield systematic changes on faculty confidence, knowledge, and behaviors. Moreover, FDPs also need support from the department and need sustained strategic support to ensure continued effectiveness. 相似文献

Currently, praziquantel is the only drug of choice for treatment of schistosomiasis. Reports of praziquantel resistance raise concerns about future control of the disease. Therefore, the search for new schistosomicidal drugs is eminent. In this study, the effect of a novel benzimidazole-derived compound (compound BTP-Iso) was assessed in mice harboring adult Schistosoma mansoni (Egyptian strain). Mice were treated 42 days p.i. with compound BTP-Iso using two treatment regimens (200 or 300 mg/kg). In both regimens, there were significant reductions in the number of recovered S. mansoni worms especially females and in immature ova, in addition to a significant reduction in the number and size of hepatic granulomata. A dose of 300 mg/kg resulted in a significant decrease in intestinal and hepatic tissue egg loads. Effect on schistosomes was confirmed by scanning electron microscopy, where adult worms recovered from mice treated with 200 mg/kg of compound BTP-Iso revealed tegumental alternations, characterised by swelling of tegumental ridges, bleb formation, and mild erosion in male worms; however in females, there were extensive erosion and destruction of the tegumental surface. These promising results may encourage future use of compound BTP-Iso in the treatment of schistosomiasis. However, more research is needed to detect the effect of compound BTP-Iso on early developmental stages of S. mansoni and on other species of human schistosomes. 相似文献
