Reconstructive surgery for burn patients

Reconstructive surgery in burn patients is difficult because of the intense scarring and the necessity to carry out multiple operative procedures for different reconstructive needs in a single patient. The primary aim of the surgeon is to prevent hypertrophic scar by early wound closure, and proper postburn treatment using a combination of silicone gel, splinting, and pressure therapy. Reconstructive procedures should be deferred until the wounds have matured. Accurate preoperative assessment and appreciation of the true tissue deficiency, appropriate application of different reconstructive options, and the establishment of the priorities of reconstruction in relation to individual requirements are essential for a successful outcome. In general, functional needs have to be met before attending to aesthetic concerns and priority should be given to restore active before passive function. Different reconstructive options using direct closure, skin grafts, flaps, free tissue transfer, and tissue expansion are discussed.published_or_final_versio

Monitoring trail: on fast link failure localization in all-optical WDM mesh networks

We consider an optical layer monitoring mechanism for fast link failure localization in all-optical wavelength-division-multiplexing (WDM) mesh networks. A novel framework of all-optical monitoring, called monitoring trail (m-trail), is introduced. It differs from the existing monitoring cycle (m-cycle) method by removing the cycle constraint. As a result, m-trail provides a general all-optical monitoring structure, which includes simple, nonsimple m-cycles, and open trails as special cases. Based on an in-depth theoretical analysis, we formulate an efficient integer linear program (ILP) for m-trail design to achieve unambiguous localization of each link failure. The objective is to minimize the monitoring cost (i.e., monitor cost plus bandwidth cost) of all m-trails in the solution. Numerical results show that the proposed m-trail scheme significantly outperforms its m-cycle-based counterpart.published_or_final_versio

Monitoring Cycle Design for Fast Link Failure Localization in All-Optical Networks

A monitoring cycle (m-cycle) is a preconfigured optical loop-back connection of supervisory wavelengths with a dedicated monitor. In an all-optical network (AON), if a link fails, the supervisory optical signals in a set of m-cycles covering this link will be disrupted. The link failure can be localized using the alarm code generated by the corresponding monitors. In this paper, we first formulate an optimal integer linear program (ILP) for m-cycle design. The objective is to minimize the monitoring cost which consists of the monitor cost and the bandwidth cost (i.e., supervisory wavelength-links). To reduce the ILP running time, a heuristic ILP is also formulated. To the best of our survey, this is the first effort in m-cycle design using ILP, and it leads to two contributions: 1) nonsimple m-cycles are considered; and 2) an efficient tradeoff is allowed between the monitor cost and the bandwidth cost. Numerical results show that our ILP-based approach outperforms the existing m-cycle design algorithms with a significant performance gain.published_or_final_versio

Analysis of recurrence after surgical treatment of advanced laryngeal carcinoma

The pattern of recurrences after surgical treatment of 276 patients with stage T3 and T4 laryngeal carcinoma was reviewed. Nodal recurrence was the commonest site and occurred mainly in patients with supraglottic and transglottic carcinoma. Distant metastasis was the second commonest site of recurrence, and the most distant metastases developed without locoregional recurrence. Local recurrence alone was uncommon in patients treated with primary surgery.published_or_final_versio

Reconstruction after craniofacial trauma

Management of craniofacial trauma has became a sophisticated branch of reconstructive surgery in the last 20 years. New operative techniques and advanced technologies have evolved to allow much better treatment results to be achieved. The general principles of diagnosis and management of craniofacial trauma are discussed. The approach to individual fractures is also highlighted.published_or_final_versio
