Authors: Bohman Leif-Erik , Pierce John , Stephen James H. , Sandhu Sukhmeet , Lee John Y. K.
Published: October 2014

Object

Fully endoscopicmicrovascular decompression (E-MVD) of the trigeminal nerve was initially described more than 1 decade ago, but has not yet gained wide acceptance. The authors present the experience of their first 47 consecutive E-MVDs for trigeminal neuralgia (TN).

Methods

All surgeries were performed by a single surgeon (J.Y.K.L.) at the Pennsylvania Hospital at the University of Pennsylvania. Patients prospectively completed pain scales before and after surgery by using the Brief Pain Inventory–Facial outcomes tool. All patients were called on the telephone, and the same outcome tool was administered without reference to their preoperative pain status.

Results

Forty-seven patients (17 men) were identified and enrolled. Forty (85%) had Burchiel Type 1 TN. Vascular compression was observed at surgery in 42 patients (89%). No surgery was aborted or converted to microscope. One patient suffered permanent hearing loss, for a permanent neurological morbidity rate of 2%. Overall improvement in pain outcomes was excellent, with a median maximum pain intensity preoperatively of 10 and postoperatively of 0 (p< 0.0001). The mean interference with global function scores were 6.2 preoperatively and reduced to 1.0 at last follow-up (p < 0.0001). The mean interference with facial function was 7.3 preoperatively and reduced to 1.2 at last follow-up (p < 0.0001). The mean follow-up period after surgery was 15 ± 8 months.

Conclusions

In experienced hands, E-MVD offers superb visualization and illumination and is both safe and effective, at least in the short term. Further longer-term study is needed to compare E-MVD to traditional microscopic MVD.

Object

Endoscopic endonasal treatment of petrous apex cholesterol granulomas allows for a natural drainage pathway into the nasopharynx. Because of the limited number of case series in the literature, there is limited evidence of recurrence rates and outcomes following endoscopic endonasal management. The purpose of this study was to determine the surgical outcomes of endoscopic endonasal approaches in the treatment of cholesterol granulomas of the petrous apex.

Methods

A systematic literature review was performed using PubMed for articles published from January 1980 to April 2014 to identify all studies reporting outcomes for endoscopic endonasal surgical management of cholesterol granulomas of the petrous apex. Operative approach, use of a stent, symptom outcome, restenosis, cyst recurrence, reoperation, and complications were extracted from included studies.

Results

A total of 53 patient cases were included from 22 relevant studies. The mean age was 41 years, and 26 patients (49%) were female. Stents were used in 45.1% of cases. Symptom resolution or improvement was seen in 98.6% of cases at follow-up (mean follow-up 20 months). Complications were reported in 13.2% of cases, with the most common complication being epistaxis. Restenosis on follow-up office endoscopic examination occurred in 9 of 45 cases (20.0%). Only 4 of these restenosis cases resulted in symptomatic cyst recurrence, resulting in an overall recurrence rate of 7.5%. The mean time from surgery to cyst recurrence was 13.5 months. The rate of symptomatic cyst recurrence was 10.7% in cases without the use of a stent compared with 4.3% in cases with stent placement (p = 0.6).

Conclusions

Based on current literature, endoscopic endonasal approaches result in a high rate of symptom improvement or resolution. Complication rates are lower than prior case series that have utilized open approaches. Asymptomatic restenosis can be managed conservatively, since it is associated with symptomatic cyst recurrence less than half of the time. This study revealed a nonsignificant trend toward a decrease in symptomatic cyst recurrence when a stent was used, but further work is needed to clarify its impact.

Natural history in newspapers: Dugald Semple (1884–1964), Ayrshire naturalist and nature journalist
Authors: Moore P. G.
Published: October 2014

Dugald Semple (1884–1964), living in Ayrshire, Scotland, was a prolific twentieth-century author of books and articles in local newspapers on natural history, as well as on diet and simple living. Forsaking a conventional urban life he chose to live close to nature in rural surroundings. Espousing vegetarianism he emulated Thoreau, following for fifty years a Ghandi-like philosophy of simplicity while earning enough from his writings and lecturing to provide for what he could not grow himself. It was his life outdoors and his enthusiasm for the natural world that he imparted not only in the printed word, but also in lectures to all who were prepared to listen. He illustrated many of his articles with his own photographs, a collection of which survive as deteriorating glass-quarter-plate negatives and lantern slides, along with three decrepit, but extensive, scrapbooks of his personal press cuttings. These form the basis for his contribution to the popularization of natural history, which deserves to be more widely recognized.
Juan Cristóbal Gundlach's contributions to the knowledge of Puerto Rican birds and his influence on the development of natural history in Puerto Rico
Authors: Wiley James W. , Frahnert Sylke , Aguilera Román Rafaela , Eckhoff Pascal
Published: October 2014

The German naturalist, Juan Cristóbal Gundlach (1810–1896), resided in Cuba for the last 57 years of his life, except for two expeditions to Puerto Rico in 1873 and 1875–1876, when he explored the southwestern, western, and northeastern regions. Gundlach made representative collections of the island's fauna, which formed the nucleus of the first natural history museum in Puerto Rico. He substantially increased the number of species known from the island, and was the first naturalist to make meticulous observations and produce detailed reports of the island's natural history. Gundlach greatly influenced other naturalists in the island, so that a period of concerted advancement in knowledge of natural history occurred in the 1870s. That development coincided with the establishment of the first higher education institutions in the island, including the first natural history museum. The natural history museums eventually closed, and only a few of their specimens were passed to other institutions, including foreign museums. None of Gundlach's and few of his contemporaries’ specimens have survived in Puerto Rico.
La mémoire volontaire de l'écrivain médiéval : aspects et enjeux de la remembrance

Glenohumeral Pressure With Surface Replacement Arthroplasty Versus Hemiarthroplasty
Authors: Petraglia Carmen A. , Ramirez Miguel A. , Tsai Michael A. , Parks Brent G. , Murthi Anand M.
Published: October 2014

It is not known whether significant differences in the glenohumeral center of pressure and contact pressure exist between surface replacement arthroplasty and hemiarthroplasty compared with the native joint. Twelve fresh-frozen cadaveric shoulders were dissected free of soft tissue, and the joint capsule was removed. The scapula was potted with the glenoid parallel to the ground. A pressure-sensitive sensor was placed in the glenohumeral joint, and each specimen was tested in sequence: intact, surface replacement, and hemiarthroplasty. Loading was done with a 440-N compression load at 0.5 Hz with the shoulder in 4 different positions. The center of pressure and contact pressure were measured at each position. The glenohumeral contact pressure with surface replacement was not different from intact pressure in 2 arm positions. Pressure with hemiarthroplasty was significantly different compared with the intact shoulder at all 4 arm positions and compared with the surface replacement group at 2 arm positions (
P
≤.05). Change in the anterior-posterior center of pressure from intact was significantly smaller with surface replacement compared with hemiarthroplasty with the humerus at 0° flexion/0° abduction and at 0° flexion/90° abduction (1.11±0.89 mm vs 2.38±1.62 mm,
P
=.02, and 0.68±0.50 mm vs 2.37±2.0 mm,
P
=.01, respectively). Change in the superior-inferior center of pressure was significantly smaller with surface replacement vs hemiarthroplasty at 0° flexion/0° abduction and at 90° flexion/90° abduction (0.98±1.16 mm vs 2.33±1.38 mm,
P
=.02, and 1.50±1.28 mm vs 2.90±1.92 mm,
P
=.04, respectively). Compared with hemiarthroplasty, surface replacement arthroplasty more closely replicated the contact pressure and center of pressure in the intact glenohumeral joint.
Lyme Arthritis of the Pediatric Ankle
Authors: Aiyer Amiethab , Walrath Jessica , Hennrikus William
Published: October 2014

Lyme arthritis results from acute inflammation caused by the spirochete
Borrelia burgdorferi.
The number of cases per year has been rising since 2006, with a majority of patients being affected in the northeastern United States. Development of Lyme arthritis is of particular importance to the orthopedic surgeon because Lyme arthritis often presents as an acute episode of joint swelling and tenderness and may be confused with bacterial septic arthritis. Considering the vast difference in treatment management between these 2 pathologies, differentiating between them is of critical importance. Septic arthritis often needs to be addressed surgically, whereas Lyme arthritis can be treated with oral antibiotics alone. Laboratory testing for Lyme disease often results in a delay in diagnosis because many laboratories batch-test Lyme specimens only a few times per week because of increased expense. The authors present a case of Lyme arthritis in the pediatric ankle in an endemic region. No clear algorithm exists to delineate between septic arthritis and Lyme arthritis of the joint. Improved clinical guidelines for the identification and diagnosis of Lyme arthritis of the ankle are important so that appropriate antibiotics can be used and surgery can be avoided.
Digital Breast Tomosynthesis Findings after Surgical Lipomodeling in a Breast Cancer Survivor
Authors: Daye Dania , Conant Emily F.
Published: October 2014

Autologous fat grafting or lipomodeling is a newly-adopted technique that is gaining increasing popularity in the treatment of contour deformities following breast conservation therapy. Here, we describe the case of a 47-year-old woman with a prior history of breast cancer treated with a lumpectomy and radiation therapy. She underwent lipomodeling not only of her treated breast but also of the contralateral breast. She presented for her annual mammogram which was performed with digital breast tomosynthesis. On imaging, a space-occupying lesion of mixed density was seen, expanding the lumpectomy site. There was also subtle distortion in the contralateral, non-treated breast. This case aims to highlight the mammographic and tomosynthesis findings seen following lipomodeling that may present diagnostic challenges in this patient population.

Authors: Hayes Michael C. , Rubin Stephen P. , Reisenbichler Reginald R. , Wetzel Lisa A.
Published: October 2014

Emigration was evaluated for hatchery Chinook salmon (Oncorhynchus tshawytscha) microjacks (age-1 mature males) and immature parr (age-1 juveniles, both sexes) released from both a hatchery and a natural stream (fish released as fry). In the hatchery, volitional releases (∼14 to 15 months post-fertilization) to an adjacent river occurred during October–November. The hatchery release was monitored by using an experimental volitional release that diverted fish to a neighboring raceway. Fish captured during the experimental release (range 361–4,321 volitional migrants) were made up of microjacks and immature parr. Microjacks were found only in the migrant samples, averaged 18% (range 0–52%) of all migrants, and were rarely found in non-migrant samples. In comparison, immature parr were common in both the migrant and non-migrant samples. Microjacks were significantly longer (9%), heavier (36%), and had a greater condition factor (16%) than migrant immature parr (P < 0.01). In addition, they differed significantly (P < 0.01) from non-migrant immature parr; 10% longer, 44% heavier and 14% greater condition factor. In natural streams, microjacks were captured significantly earlier (P < 0.01) than immature parr during the late-summer/fall migration and comprised 9–89% of all fish captured. Microjacks have the potential to contribute to natural spawning populations but can also represent a loss of productivity to hatchery programs or create negative effects by introducing non-native genes to wild populations and should be monitored by fishery managers.
« Tout a un maître » : possession individuelle, usage communautaire de la nature et gestion environnementale participative dans la réserve extractiviste ‘Quilombo do Frechal’ (Brésil)
Authors: Tassan Manuela
Published: October 2014

En adoptant une perspective anthropologique, cet article essaie de montrer comment certaines formes d'appropriation individuelle et d’usage communautaire de la nature peuvent non seulement coexister, mais constituer également un élément important d'identification sociale au sein d’une « communauté traditionnelle » de l’Amazonie brésilienne. Le texte attire également l’attention sur les conséquences que pourraient avoir l’adoption d’une approche qui n’envisage pas ou qui méconnaît le rôle de la possession individuelle de la nature. L’article suggère qu’une approche stéréotypée ou idéologique du concept d’«  usage commun » peut avoir des répercussions inattendues et problématiques sur le processus de mise en œuvre d’aires protégées établies dans un but social et environnemental, telles que les réserves extractivistes. En soutenant une gestion partagée entre le gouvernement et les communautés locales, ce type de réserves brésiliennes fut créé principalement pour protéger et valoriser les relations coutumières des humains avec le territoire. Dans cet article, l’auteure analyse le cas de la Reserva Extrativista Quilombo do Frechal (Maranhão, Brésil), habitée par une communauté de descendants d’esclaves africains (quilombo), qui se consacre essentiellement à une agriculture de subsistance sur brûlis (slash and burn).
L’art contemporain au prisme des biotechnologies
Authors: Voison Catherine
Published: October 2014

En utilisant la matière biologique comme outil et matériau de leurs productions, les bio-artistes reconfigurent la nature in vivo et réalisent en laboratoires des entités vivantes inédites. La manipulation et la transformation, des organismes naturels, qu’ils soient microscopiques (à l’état de cellules) ou non, permettent à ces artistes d’établir de nouveaux rapports entre l’homme et le milieu vivant, et rendent de plus en plus complexe le sens que nous accordons au mot « nature » ou à ses occurrences. Toutefois, les organismes vivants renaturés par les artistes sont autant d’incarnations du pire et/ou du meilleur des mondes. En marge de toute recherche appliquée à la médecine et à l’industrie, les altérités biologiques qui sortent des coulisses de la science pour être exposées dans le monde de l’art, anticipent non sans risque, les conséquences sociales et environnementales de l’artificialisation des mécanismes naturels de la vie.

Culture is a track of human existence in which humanity pursues its self-limits in invention, and explores human origins and the meaning of life (Miyazaki, 2002). A product designer imparts new meaning and value to products through innovative methods, and creates an impressive product that expresses the ideas he/she wishes to convey. Consequently, the core value of a product is to increase its emotional energy through innovation and to use a “story” to obtain meaningful situational and sentimental values that exemplify human affection. The author investigate the problem of a “legend” in grasping the thread of a story in design. Regarding the design of a cultural product, we discuss the application of a legend from the perspective of an emotional value that reflects local features and local cultural values through local stories. The author investigate the introduction of a story into the design of culturally creative products and explore the problem-solving ability involved in a story by discussing the perspectives of consumers who buy story-based cultural products that create experiences regarding the 5 senses through story-based design.
Managing International Information Technology Project Relationships
Authors: Haried Peter , Huang Chun-Lung
Published: October 2014

Many organizations in recent years have adopted an offshore model to deliver most or part of their information technology needs. While offshoring can be associated with significant cost savings and implementation benefits, it can also be a challenge to effectively manage the international client-vendor relationship. Thus, it is argued that the effective management, coordination and structuring of the international client-vendor relationship is critical to project management success. In this paper an agency perspective is applied to examine the management of international client-vendor relationships in offshore information technology (IT) projects. This paper synthesizes key relational findings from eight offshore IT projects consisting of 29 client interviews. The authors' findings suggest that the relational tenets of agency theory (shirking, privately held information, task programmability and monitoring) play key roles in successfully managing international project relationships. Based on the findings, propositions are presented to guide future offshore IT project research and organizations to successfully manage and structure their client-vendor relationships.
Model for Improving Productivity Without Impacting Quality of Deliverables in IT Projects
Authors: Mohapatra Sanjay , Sreejesh S
Published: October 2014

This research has developed a theoretical model that will help to improve productivity without reducing quality in software projects. It has been observed that while trying to increase productivity, quality gets hit in software projects. However, customer requirements in these projects demand that the projects be delivered on time without having defects or bugs in the final deliverables. Thus, it becomes important to identify variables that would increase productivity without compromising the quality. In the present study, through literature review different variables were identified that would affect both productivity and quality simultaneously. The data were collected from 36 software projects and were analysed to check the relationships between the identified variables, productivity and quality. Using structured equation modelling it was found that level of application complexity, training, level of client support, reusing existing code and quality of document management system significantly impact productivity without compromising quality. The findings can be used in projects engaged in customized software development as well as in commercial software development.

Published: October 2014

In the domain of image processing, image segmentation has become one of the key application that is involved in most of the image based operations. Image segmentation refers to the process of breaking or partitioning any image. Although, like several image processing operations, image segmentation also faces some problems and issues when segmenting process becomes much more complicated. Previously lot of work has proved that Rough-set theory can be a useful method to overcome such complications during image segmentation. The Rough-set theory helps in very fast convergence and in avoiding local minima problem, thereby enhancing the performance of the EM, better result can be achieved. During rough-set-theoretic rule generation, each band is individualized by using the fuzzy-correlation-based gray-level thresholding. Therefore, use of Rough-set in image segmentation can be very useful. In this paper, a summary of all previous Rough-set based image segmentation methods are described in detail and also categorized accordingly. Rough-set based image segmentation provides a stable and better framework for image segmentation.

Published: October 2014

In order to check whether there are defects in GIS (gas-insulation-switchgear), it is necessary to do AC voltage withstand test before putting into operation. According to the standards, when doing AC voltage withstand test after GIS expansion or maintenance, the original neighboring parts should be power cut and grounded. For the double bus substation,it means that the whole substation should be power cut, which will decrease the power supply reliability of the grid and have a tremendous impact on the power grid To solve the problem, this paper presents a new AC voltage withstand test method for GIS without power cut, and explains principles and field applications of this method.

Published: October 2014

The objective of this study was to investigate the effects of salinity on power generation and microbial community structure in the microbial fuel cell (MFC). Three two-chamber MFCs (MFC-A, MFC-B, MFC-C) were used to conduct experiments. The MFC-A was operated sequentially using solutions of 0, 20, 40, 60, and 70 g/L NaCl in the anode chamber of the cell. The MFC-B was operated with solutions of 0 and 40 g/L NaCl and the MFC-C with solutions of 0 and 70 g/L NaCl. Results showed that the salinity inhibited power generation in all the MFCs. In the MFC-A, the maximum voltage outputs and CEs decreased from 660 to 130 mV and from 67% to 4%, respectively, with the NaCl concentrations from 0 to 70 g/L. However, the NaCl concentrations did not affect the removal efficiency of substrate (glucose) in the MFC, which reached 100% at the end of every cycle. Moreover, voltages could be recovered to the maximum value (630 mV) within 60 h after replacing the salt solutions with water. With the solutions of 40 and 70 g/L NaCl in the MFC-B and MFC-C, respectively, no obvious electricity was generated after two cycle operations.

Authors: Dai Jin Song , Cao Fu Liang
Published: October 2014

Maximum entropy (Maxent) modeling was used to predict the potential climate habitat distribution of Chinese hybrid poplar (clone I-63, I-69 and I-72). Occurrence data were collected from literatures. The Maxent model performed better than random with an average cross-validated AUC value of 0.96. Under the three future climate scenarios (emission scenarios A1B, A2 and B1), the geographic distribution of suitable habitat would shift from southwest to northeast, the suitable habitat area of scenario A1B increased most compared to other two, the ranking of the loss habitat area was scenario B1 > scenario A2 > scenario A1B, and the gain habitat area was scenario A1B > scenario A2 > scenario B1. The results of this work could be used as scientific basis for adapting and mitigating Chinese hybrid poplar planting to a climate change.

Authors: Wang Sheng Quan , Sun Da Jun , Zhang You Wen
Published: October 2014

Efficient intra-cluster communication on the MAC layer in the underwater acoustic sensor networks has always been the primary concern. However, the existing MAC protocols are not suitable for the intra-cluster communication. In this paper, we analyze some typical MAC protocols and the reasons for their unsuitability. We propose IC-MAC, an Intra-cluster MAC protocol based on a model of intra-cluster nodes location. This protocol realizes the slot synchronization between nodes, sleep mechanism and collision avoidance. Finally, we simulate IC-MAC, TDMA and T-Lohi for comparison. The results show IC-MAC has better performance in terms of throughput and end-to-end delay. Our design is also energy-efficient.
