Emergent off-pump complete myocardial revascularization in dextrocardia   总被引:1,自引:0,他引:1  
Dextrocardia is a rare condition not spared by coronary artery disease. We report the case of a 72-year-old patient with dextrocardia associated with situs inversus totalis who presented to our Institution with acute myocardial infarction complicated by congestive heart failure. Due to the severe general conditions of the patient, an emergent off-pump complete myocardial revascularization was undertaken. The patient tolerated the procedure well and was asymptomatic at discharge. The technical aspects encountered in the setting of mirror-image anatomy and the advantages of off-pump myocardial revascularization in the critically ill patient are discussed.  相似文献

A case is reported of a solid variant of infiltrating papillary carcinoma of the breast with mucinous differentiation in a 74-year-old woman. Macroscopically, the tumor was solid and lobular, 4.5 cm in diameter. Light microscopy showed solid papillary invasive carcinoma mixed with infiltrating ductal carcinoma, not otherwise specified. Abundant intracellular and extracellular acid mucin produced by the solid papillary tumor cells was proven histochemically by: PAS, PAS-D, mucicarmine and alcian blue. Immunohistochemically, the papillary carcinoma cells were strongly reactive to estrogen receptors, and weakly to moderately reactive to smooth muscle actin. We suggest that papillary carcinoma of the breast could have potentially high degree of aggressiveness, and that differential diagnosis of these rare tumors might be a histopathological problem.  相似文献

Tumors of the bladder, particularly urothelial carcinoma (UC) are very rare malignant diseases in young people. They mostly occur in elder persons of male gender. We present 8 patients below 35 years of age, (average age 24.7), in whom the presence of UC was verified. The main symptom was total or terminal hematuria. The results showed that 5 patients had low-risc group of tumors (G1, pTa), while 3 tumors were of medium-risk group (G2, pT1). We concluded that UC in young people was low-grade and non-invasive. However, for better evaluation it was necessary to observe patients for longer period of time.  相似文献

In an outpatient rehabilitation setting, both patients’ use and therapists’ knowledge of complementary and alternative medicine (CAM) varies widely. Based on this observation and a recognition of CAM as an emerging practice area for rehabilitation professionals, it was felt that a thorough and consistent approach to the education and orientation of physical therapists to the world of CAM and integrative care was needed. This special interest paper will describe one center’s approach, development, and use of a unique and comprehensive training manual designed to provide both a structured and standardized approach for educating physical therapists about CAM and related therapeutic modalities. This innovative teaching tool allows for multiple methods of content delivery within a multidisciplinary format and can be used for those who practice currently or desire to practice in an integrative care environment.  相似文献
