Reconstructive Algorithm

AbstractResection and reconstruction of midface involve complex ablative and reconstructive tools in head and oncology and maxillofacial prosthodontics. This region is extraordinarily important for long-term aesthetic and functional performance. From a reconstructive standpoint, this region has always been known to present challenges to a reconstructive surgeon due to the complex three-dimensional anatomy, the variable defects created, combination of the medical and dental functionalities, and the distance from reliable donor vessels for free tissue transfer. Another challenge one faces is the unique features of each individual resection defect as well as individual patient factors making each preoperative planning session and reconstruction unique. Understanding the long-term effects on speech, swallowing, and vision, one should routinely utilize a multidisciplinary approach to resection and reconstruction, including head and neck reconstructive surgeons, prosthodontists, speech language pathologists, oculoplastic surgeons, dentists, and/or craniofacial teams as indicated and with each practice pattern. With this in mind, we present our planning and reconstructive algorithm in midface reconstruction, including a dedicated focus on dental rehabilitation via custom presurgical planning.

Environmental protection efforts require numerous advanced technologies to prevent and monitor the health and ecological effects associated with abiotic and biotic systems. Development of innovative tools and methodologies with the help of multidisciplinary approach to assess the transport, accumulation, and impact of pesticides will avoid the long-term effects in the environment. The lack of information about the pesticides hampers the labeling requirements that lead to misuse and discharge of pesticide-contaminated effluents into the water resources. This chapter covers the information on major sources of pesticides, chronic impacts, labeling of pesticides, multidisciplinary approach for monitoring, current cost-effective technologies, pros and cons of current technologies, and future perspectives of the pesticide monitoring technologies.

On the heels of the rural ‘land grab’ debate, the ongoing urban transition combined with large-scale urban infrastructure investments and land scarcity forces us to also pay more attention to issues of land in urban discussions. Yet how can we conceptualise land-related problems in order to connect and integrate rural and urban debates in overarching discussions of development? In this commentary, we argue for moving beyond the directly visible outcomes and presumed ‘culprits’ of land investments by critically analysing indirect and long-term effects of land acquisitions on people’s livelihoods as well as the differentiation of these effects for different actors. We propose three specific arguments to disentangle the grab–development dichotomy: 1) placing a focus on the sequential chain of effects of displacement; 2) paying more attention to the ambivalent roles and contradictory interests of different actors; and 3) taking the three-dimensional aspects of land development into account.

In patients with haemophilia (PWH) (from Greek “blood love”), the long-term consequences of repeated haemarthrosis include cartilage damage and irreversible arthropathy, resulting in severe impairments in locomotion. Quantifying the extent of joint damage is therefore important in order to prevent disease progression and compare the efficacy of treatment strategies. Musculoskeletal impairments in PWH may stem from structural and functional abnormalities, which have traditionally been evaluated radiologically or clinically. However, these examinations are performed in a supine position (i.e., non-weight-bearing condition). We therefore suggest three-dimensional gait analysis (3DGA) as an innovative approach designed to focus on the functional component of the joint during the act of walking. This is of the utmost importance, as pain induced by weight-bearing activities influences the functional performance of the arthropathic joints significantly. This review endeavors to improve our knowledge of the biomechanical consequences of multiple arthropathies on gait pattern in adult patients with haemophilia using 3DGA. In PWH with arthropathy, the more the joint function was altered, the more the metabolic energy was consumed. 3DGA analysis could highlight the effect of an orthopedic disorder in PWH during walking. Indeed, mechanical and metabolic impairments were correlated to the progressive loss of active mobility into the joints.

Long-term pavement performance is highly dependent on its initial condition. High initial roughness leads to higher maintenance and rehabilitation costs, to shorter service life, and to significant reduction in riding quality. A performance-based specification applicable for new and rehabilitated warranted pavements is developed and presented here. The primary purpose of this specification is control of the initial longitudinal roughness of pavements, which will lead to smoother pavements and hence satisfactory long-term performance. In this specification, pavement roughness is measured by using Class I or calibrated Class II profilometers, such as infrared and laser profilometers. Tests are performed on each asphalt layer before the next layer is constructed. Three criteria are considered in the specification: surface tolerance, roughness indices, and repeated waves. It should be noted that this specification focuses on the functional performance of pavements and does not directly address their structural performances. A user-friendly software is developed to implement this specification. The software is capable of simulating straightedge inspections, calculating roughness statistics, and performing frequency analyses, such as power spectral analysis. With the software, a pavement section can be evaluated, tested, and analyzed in few minutes. Highway agencies as well as contractors will benefit from implementing this specification. Highway agencies will benefit by being able to achieve the goal of having safe, smooth, and economic pavements, and contractors will benefit by reducing maintenance cost during maintenance and warranty periods. Also, contractors will get quick results and meaningful feedback to the paving operation. A payment structure, including bonus payments for extended service lives, is included in the specification. This payment structure is based on the long-term effects of the initial roughness on the pavement life-cycle costs. The bonus program will encourage contractors to achieve higher levels of quality.

Through the introduction of food chain, our paper analyzed the short and long-term effects that ocean garbage patch provided to ocean environment. We used plastic density, quality of ocean water and the ratio of organisms eating plastic to examine effects of plastic debris. We described effect as a three-dimensional vector and creatively employed the three dimensional coordinate and sphere to explain the effects. Finally, we put forward some feasible measures to relieve the problem.

Nasoalveolar Molding

Objective: This objective of this study was to determine the effect of presurgical nasoalveolar molding on long-term nasal shape in complete unilateral clefts. Design: The study was retrospective, and the subjects were chosen at random. Nasal casts of the subjects were scanned in three dimensions. Each nose was best fit to its mirror image, and a numerical asymmetry score was determined. Setting: All patients were treated at the Institute of Reconstructive Plastic Surgery, NYU Medical Center, New York, New York. Patients: The study subjects (n = 10) were selected from a group that had undergone presurgical nasal molding in conjunction with alveolar molding. The control subjects (n = 10) were selected from a group that had undergone presurgical alveolar molding alone. Interventions: All subjects underwent presurgical orthopedic treatment until the age of approximately 4 months at which time the primary surgery was performed. Main Outcome Measure: The nasal shape following nasal molding should be more symmetrical than if molding had not been done. Results: The mean asymmetry index for the nasoalveolar molding group was 0.74, and the control group was 1.21. This difference was statistically significant (p < .05). Conclusions: Presurgical nasoalveolar molding significantly increases the symmetry of the nose. The increase in symmetry is maintained long term into early childhood. The limitations of this study include (1) asymmetry alone is not an adequate shape result in most situations, (2) the children evaluated in this study were not fully grown, and (3) the control group was not age matched.

Background: Three-dimensional printing provides an exciting opportunity to customise upper-limb prostheses. Objective: This review summarises the research that assesses the efficacy and effectiveness of three-dimensional printed upper-limb prostheses. Study design: Systematic review. Methods: PubMed, Web of Science and OVID were systematically searched for studies that reported human trials of three-dimensional printed upper-limb prostheses. The studies matching the language, peer-review and relevance criteria were ranked by level of evidence and critically appraised using the Downs and Black Quality Index. Results: After removing duplicates, 321 records were identified. Eight papers met the inclusion criteria. No studies used controls; five were case studies and three were small case-series studies. All studies showed promising results, but none demonstrated external validity, avoidance of bias or statistically significant improvements over conventional prostheses. The studies demonstrated proof-of-concept rather than assessing efficacy, and the devices were designed to prioritise reduction of manufacturing costs, not customisability for comfort and function. Conclusion: The potential of three-dimensional printing for individual customisation has yet to be fully realised, and the efficacy and effectiveness to be rigorously assessed. Until randomised controlled trials with follow-up are performed, the comfort, functionality, durability and long-term effects on quality of life remain unknown. Clinical relevance Initial studies suggest that three-dimensional printing shows promise for customising low-cost upper-limb prosthetics. However, the efficacy and effectiveness of these devices have yet to be rigorously assessed. Until randomised controlled trials with follow-up are performed, the comfort, functionality, durability and long-term effects on patient quality of life remain unknown.
