Design of Plethora Bridge at Kanyakumari
The discrete tourist place such as Vivekananda Rock Memorial and Thiruvalluvar Statue firmed at the offshore of Kanyakumari is connected by the Plethora Bridge. This bridge is designed to connect the span of 550 m between Kanyakumari sea shore and Vivekananda Rock Memorial and to allied the short span of 110 m between anterior bridge and Thiruvallur Statue. It consists of a Multi Cellular Concrete Box Girder Deck Slab, Bearing, Pier, Pile Foundation and Staircase. A Multi celled prestressed concrete box girder deck is designed by Prestressed method as per the recommendation of IRC: 21-2000, Clause 304.2.1, IRC:6-2000 by using Freyssinet type anchorages with M60 grade concrete and Fe 415 grade steel. Reinforced bearing plate is used in between Pier and Deck. Reinforced bearing plate is designed by working stress method with M30 grade concrete and Fe 415 grade steel. The Solid RCC Pier is designed for the axial dead load and live load from the slab, girders, deck beam. Pile Foundation is designed based on safe load bearing in the soil and water current. Staircase is designed by limit state method with M25 grade concrete and Fe 415 grade steel
Continuous ambulatory peritoneal dialysis catheter placement: Is omentectomy necessary?
<b>Context:</b> There are different methods of continuous ambulatory peritoneal dialysis (CAPD) catheter placement. Open surgical technique is a widely followed method. The complication rate following catheter placement varies and catheter blockage due to omental plugging is one of the main reasons. <b>Aim:</b> To analyze the need for routine omentectomy during CAPD catheter placement. <b>Materials and Methods:</b> This was a retrospective analysis of 58 CAPD catheter placements performed between July 2002 and June 2007. Tenckhoff double cuffed catheter was used in all. The postoperative complications were analyzed. <b>Results:</b> There were 44 males and 14 females. The mean age was 51 years ranging from 15 to 76 years. Of these, 40 (69%) patients underwent omentectomy (group A) and 18 (31%) did not (group B). Laparoscopic and open techniques were performed in 5 and 53 patients, respectively. Omentectomy was not performed in 13 patients with open technique and all the five in the laparoscopic group. One patient in group A developed hemoperitoneum which was treated conservatively. None from group A developed catheter blockage, whereas five (27.8%) from group B developed catheter blockage postoperatively. The median time interval between the primary procedure and development of catheter blockage was 45 days (ranged from 14 to 150 days). <b>Conclusions:</b> Omentectomy during CAPD catheter placement prevents catheter blockage and secondary interventions
Renal cell carcinoma associated with granulomatous reaction
Granulomatous inflammation is a distinctive pattern of chronic inflammatory reaction characterized by accumulation of epithelioid histiocytes and multinucleate giant cells. The cause of granulomas can be infectious or non-infectious. Granulomas have been described within the stroma of malignancies like carcinomas of the breast and colon, seminoma and Hodgkin′s lymphoma, where they represent T-cell-mediated reaction of the tumor stroma to antigens expressed by the tumor. Granulomatous reaction in association with renal cell carcinoma (RCC) is uncommon, with only few published reports in the literature. We describe three cases of conventional (clear cell) RCC associated with epithelioid granulomas within the tumor parenchyma
