Power Rotational Interleaver on an Idma System

In this paper we are proposing an interleaver design i.e. power rotational interleaver. The basic purpose of this design is to reduce the bandwidth occupied by the interleaver. This approach provides an efficient result for multiple users. The complexity of this design is same as that of master random interleaver while the bandwidth requirement is reduced up to a great extent. On the basis of simulation results it is concluded that the performance of power rotational interleaver is as good as that is of random interleaver. Keywords: Master random interleaver, a posteriori probability, tree based interleaver

Study the demographic, clinical and surgical outcomes of endoscopic dacryocystorhinostomy

This study was done with an aim to study the demographic, clinical and surgical outcomes of Endoscopic Dacryocystorhinostomy. The records of patients who underwent Endoscopic DCR in the last five years were retrieved from the archival records of Department of Otorhinolaryngology and Head-Neck Surgery, K.G.M.U and were reviewed for demographic data, laterality, pre-operative complaints, co-morbidities, clinical and surgical profiles, adjunctive procedures, complications, and success rates at the last follow up. Result: The distribution of cases according to operation type is shown in table-7. Among the cases, Endoscopic DCR Left operation was performed in 94 (41.6%) cases while Endoscopic DCR Right operation was performed in 131 (58.0%) cases. There was one case operated with Endoscopic Bilateral DCR. On comparing pre to post op tearing status, it was found that at pre op the mean tearing score was 5.80±2.02 which was reduced to 1.17±1.35 at post op. So a mean reduction of 4.63±0.12 was observed which was significant statistically (p<0.001). Conclusion: Endoscopic DCR can be adopted the first-line surgical procedure for the treatment of acquired Nasolacrimal duct obstruction. Endoscopic DCR avoids external scar, endoscopic visualization and assessment can be done immediately with correction of pathology including endonasal pathologies (DNS, turbinate hypertrophy etc.).&nbsp

Study the quality of life post endoscopic dacryocystorhinostomy

Background & Method: Aim of this study is to Study the quality of life post Endoscopic Dacryocystorhinostomy. The records of patients who underwent Endoscopic DCR in the last five years were retrieved from the archival records of Department of Otorhinolaryngology and Head-Neck Surgery, K.G.M.U and were reviewed for demographic data, laterality, pre-operative complaints, co-morbidities, clinical and surgical profiles, adjunctive procedures, complications, and success rates at the last follow up. Result: On comparing pre to post op swelling around eye status, it was found that at pre op the mean swelling score was 2.90±2.33 which was reduced to 0.50±1.03 at post op. So a mean reduction of 2.40±0.14 was observed which was significant statistically (p<0.001). On comparing pre to post op general condition status, it was found that at pre op the mean condition score was 0.08±0.48 which was unchanged at post op. Conclusion: Endoscopic DCR has improved the treatment of Nasolacrimal duct obstruction, with outcome as comparable to external DCR. Thus the present study state Endoscopic DCR as an effective and safe alternative to external DCR with improved patient satisfaction.&nbsp
