Low grade papillary transitional cell carcinoma pelvic recurrence masquerading as high grade invasive carcinoma, ten years after radical cystectomy

BACKGROUND: Tumor recurrence following radical cystectomy for a low-grade superficial transitional cell carcinoma (TCC) is exceedingly uncommon and has not been reported previously. CASE PRESENTATION: We describe a case of a young male presenting with anorexia, weight loss and a large, painful locally destructive pelvic recurrence, ten years after radical cystoprostatectomy. The pathology was consistent with a low-grade urothelial carcinoma. After an unsuccessful treatment with cisplatin-based chemotherapy, the patient underwent a curative intent hemipelvectomy with complete excision of tumor and is disease free at one year follow-up. CONCLUSION: A literature review related to this unusual presentation is reported and a surgical solutions over chemotherapy and radiotherapy is proposed

Is the tetraneutron a bound dineutron-dineutron molecule?

In light of a new experiment which claims a positive identification, we discuss the possible existence of the tetraneutron. We explore a novel model based on a dineutron-dineutron molecule. We show that this model is not able to explain the tetraneutron as a bound state, in agreement with other theoretical models already discussed in the literature.Comment: 9 pages, 3 figures, J. Phys.

Analytical and Experimental Studies of a Divided-flow Ram-jet Combustor

Results of a theoretical and experimental study of the total pressure losses and combustion efficiencies associated with the divided-flow combustor are presented and comparisons made with the nondivided-flow combustor. The theoretical treatment indicated the range of primary-zone size, primary-zone air flow, and flame-holder pressure-loss coefficients over which the total-pressure loss through the divided-flow combustor was less than that through the nondivided-flow combustor. The experimental work indicated the range of fuel-air ratios, for a given size primary zone, over which the combustion efficiency in the divided-flow combustor was higher than that in the nondivided-flow combustor
