Background Perioperative management in autologous breast reconstruction has gained focus in recent years. This study compares two pain management protocols in patients undergoing abdominal-based free flap breast reconstruction: a past protocol (PP) and a current protocol (CP)-both intended to reduce opioid consumption postoperatively. The PP entails use of a pain catheter in the abdominal wound and the CP consists of an intraoperative nerve block in addition to refinements in the oral pain management. We hypothesize that the CP reduces opioid consumption compared to PP. Methods From December 2017 to January 2020, 102 patients underwent breast reconstruction with an abdominal-based free flap. Two postoperative pain management strategies were used during the period; from December 2017 to September 2018, the PP was used which entailed the use of a pain catheter with ropivacaine applied in the abdominal wound with continuous distribution postoperatively in addition to paracetamol orally and oxycodone orally pro re nata (PRN). From October 2018 to January 2020, the CP was used. This protocol included a combination of intraoperative subfascial nerve block and a postoperative oral pain management regime that consisted of paracetamol, celecoxib, and gabapentin as well as oxycodone PRN. Results The CP group (n = 63) had lower opioid consumption compared to the PP group (n = 39) when examining all aspects of opioid consumption, including daily opioid usage in morphine milligram equivalents and total opioid usage during the stay (p < 0.001). The CP group had shorter length of hospital stay (LOS). Conclusion Introduction of the CP reduced opioid use and LOS was shorter.

In reverse engineering area, it is rapidly developing reconstruction of surfaces from scanning or digitizing data, but geometric models of existing objects unavailable many industries. This paper describes new methodology of reverse engineering area, good strategies and important algorithms in reverse engineering area. Furthermore, proposing reconstruction of surface technique is presented. A method find base geometry and blending surface between them. Each based geometry is divided by triangular patch which are compared their normal vector for face grouping. Each group is categorized analytical surface such as a part of the cylinder, the sphere, the cone, and the plane that mean each based geometry surface. And then, each based geometry surface is implemented infinitive surface. Infinitive average surface's intersections are trimmed boundary representation model reconstruction. This method has several benefits such as the time efficiency and automatic functional modeling system in reverse engineering. Especially, it can be applied 3D scanner and 3D copier.

This paper presents the development of Artificial Neural Network models for forecasting the cost and contract duration of school reconstruction projects to assist the planners' decision-making in the early stage of the projects. 132 schools reconstruction projects in central Taiwan, which received the most serious damage from the Chi-Chi Earthquake, were collected. The developed Artificial Neural Network prediction models demonstrate good prediction abilities with average error rates under 10% for school reconstruction projects. The analytical results indicate that the Artificial Neural Network model with back-propagation learning is a feasible method to produce accurate prediction results to assist planners' decision-making process.

Background No consensus has been reached regarding the outcome of management of local recurrence after transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction. This study demonstrated the presentation, management, and outcomes of local recurrence after immediate TRAM breast reconstruction. Methods A comparison was conducted among 1,000 consecutive patients who underwent immediate breast reconstruction with a pedicled TRAM flap (TRAM group) and 3,183 consecutive patients who underwent only modified radical mastectomy without reconstruction (MRM group) from January 2001 to December 2009. The presentation, treatment, and outcome including aesthetics and overall survival rate were analyzed. Results Local recurrences occurred in 18 (1.8%) patients (TRAM-LR group) who underwent TRAM breast reconstruction and 38 (1.2%) patients (MRM-LR group) who underwent MRM only (P=0.1712). Wide excision was indicated in almost all the local recurrence cases. Skin graft was required in 4 patients in the MRM-LR group, whereas only one patient required a skin graft to preserve the mound shape in the TRAM-LR group. The breast mound was maintained in all 17 patients that survived in the TRAM-LR group even after wide excision. The overall survival rate was 94.4% in the TRAM-LR group and 65.8% in the MRM-LR group (P=0.276). Conclusions Local recurrence after immediate TRAM flap breast reconstruction could be detected without delay and managed effectively by multiple modalities without reducing overall survival rates. Breast mound reconstruction with soft autologous tissue allowed for primary closure in most of the cases. In all of the patients who survived, the contour of their reconstructed breast remained.

70년대 이후 급속히 건설된 공동주택은 시간이 경과함에 따라 구조체와 시설이 노후화 되면서 유지관리 비용이 상승하였고 또한 경제성장에 따른 생활수준의 향상으로 인해 주거공간으로의 기능을 상실하게 되었다. 이러한 이유로 인해 공동주택 재건축 수요가 창출되었고 90년대를 기점으로 활성화되었다. 그러나, 사업시행주체인 조합임원의 대부분이 비전문인이기 때문에 사업시행에 않은 문제점들이 발생하게 되었다. 본 연구에서는 이러한 문제점들을 해결하기 위한 방안으로 재건축조합의 전반적인 업무를 대행하고, 공정하고 투명한 절차에. 의해 사업을 추진할 수 있도록 공동주택 재건축사업에 대한 CM의 적용방안을 모색하고자 하며, 특히 재건축사업 추진단계별 CM업무를 제시하고자 한다. 또한 향후 재건축사업의 CM적용시 현실적으로 활용 가능한 업무를 중심으로 제안하여 조합과 CM회사에서 이를 활용할 수 있도록 하였다.

Background A pharyngocutaneous fistula is a common and difficult-to-manage complication after head and neck reconstruction. It can lead to serious complications such as flap failure, carotid artery rupture, and pharyngeal stricture, and may require additional surgery. Previous radiotherapy, a low serum albumin level, and a higher T stage have been proposed as contributing factors. We aimed to clarify the risk factors for pharyngocutaneous fistula in patients who underwent flap reconstruction and to describe our experiences in treating pharyngocutaneous fistula. Methods Squamous cell carcinoma cases that underwent flap reconstruction after cancer resection from 1995 to 2013 were analyzed retrospectively. We investigated several significant clinical risk factors. The treatment modality was selected according to the size of the fistula and the state of the surrounding tissue, with options including conservative management, direct closure, flap surgery, and pharyngostoma formation. Results A total of 127 cases (18 with fistulae) were analyzed. A higher T stage (P=0.048) and tube-type reconstruction (P=0.007) increased fistula incidence; other factors did not show statistical significance (P>0.05). Two cases were treated with conservative management, 1 case with direct closure, 4 cases with immediate reconstruction using a pectoralis major musculocutaneous flap, and 11 cases with direct closure (4 cases) or additional flap surgery (7 cases) after pharyngostoma formation. Conclusions Pharyngocutaneous fistula requires global management from prevention to treatment. In cases of advanced-stage cancer and tube-type reconstruction, a more cautious approach should be employed. Once it occurs, an accurate diagnosis of the fistula and a thorough assessment of the surrounding tissue are necessary, and aggressive treatment should be implemented in order to ensure satisfactory long-term results.

This paper collected 132 schools reconstruction projects in central Taiwan, which received the most serious damage from the Chi-Chi Earthquake. Regression analysis was implemented to build the prediction model of the cost and the duration for the collected projects. It is found that the cubic regression models are capable for predicting the cost and the duration of the projects contracted by the central agency of which the contracting awarding approach was based on the most advantageous tendering (MAT) approach. On the other hand, power regression models are capable for predicting the cost and the duration of the projects contracted through the low bid tendering (LBT) approach. It is also found that the performance of the regression prediction model differs in accordance with organizations that contracted the reconstruction projects.

Tongue reconstruction remains a major aspect of head and neck reconstructive procedures. Surgeons planning tongue reconstruction should consider several factors to optimize the overall outcomes. Specifically, various technical aspects related to tongue reconstruction have been found to affect the outcomes. Multidisciplinary teams dedicated to oncologic, reconstructive, and rehabilitative approaches play an essential role in the reconstructive process. Moreover, operative planning addressing certain patient-related and defect-related factors is crucial for optimizing functional speech and swallowing, as well as quality of life outcomes. Furthermore, tongue reconstruction is a delicate process, in which overall functional outcomes result from proper flap selection and shaping, recipient vessel preparation and anastomosis, surgical approaches to flap insetting, and postoperative management. The second part of this review summarizes these factors in relation to tongue reconstruction.
