Published: July 2015

OBJECT
Distal coil or stent migration is a rare, but potentially morbid complication of intracranial aneurysm embolization. At present, there is no established standard of surgical evacuation of displaced material—in particular, there is no consensus on the optimum time for such intervention. The authors report their positive experiences with an ultra-early surgical evacuation of 2 migrated coils and a flow-diverter stent.

METHODS
Uncontrolled coil or stent migration occurred in 3 (0.75%) of approximately 400 patients treated between 1999 and 2012 in the authors' institution. In all 3 cases, the materials moved from their intended position to the middle cerebral artery (MCA). Surgical evacuation was started immediately (within half an hour) after a futile attempt of removing them via intraarterial route, under the same anesthesia and with no active reversal of heparinization.

RESULTS
No excessive bleeding was observed. Displaced coils were extracted through an incision of a branch of MCA—the anterior temporal artery, the stent was removed through a direct incision of MCA. Recombinant tissue plasminogen activator (rtPA) was injected to the stem of the internal carotid artery toward the end of the procedure, with no discernible adverse effects. Two patients were discharged with no deficit (Glasgow Outcome Scale [GOS] Score 5); the other patient was conscious with mild hemiparesis (GOS Score 4) at discharge.

CONCLUSIONS
The experiences of these 3 cases suggest that immediate removal of a migrated stent/coil is feasible and may be effective. Indirect access to the MCA through its branch helps to shorten the time of temporary clipping of the artery to a minimum. Maintaining active heparinization and direct intraarterial injection of rtPA are helpful in promoting blood flow in the MCA.

Published: July 2015

OBJECT
The expansion of endovascular procedures for obliteration of cerebral aneurysms highlights one of the drawbacks of clip ligation through the transcranial route, namely brain retraction or brain transgression. Sporadic case reports have emerged over the past 10 years describing endonasal endoscopic clip ligation of cerebral aneurysms. The authors present a detailed anatomical study to evaluate the feasibility of an endoscopic endonasal approach for application of aneurysm clips.

METHODS
Nine human cadaveric head specimens were used to evaluate operative exposures for clip ligation of aneurysms in feasible anterior and posterior circulation locations. Measurements of trajectories were completed using a navigation system to calculate skull base craniectomy size, corridor space, and the surgeon's ability to gain proximal and distal control of parent vessels.

RESULTS
In each of the 9 cadaveric heads, excellent exposure of the target vessels was achieved. The transplanum, transtuberculum, and transcavernous approaches were used to explore the feasibility of anterior circulation access. Application of aneurysm clips was readily possible to the ophthalmic artery, A1 and A2 segments of the anterior cerebral artery, anterior communicating artery complex, and the paraclinoid and paraclival internal carotid artery. The transclival approach was explored, and clips were successfully deployed along the proximal branches of the vertebrobasilar system and basilar trunk and bifurcation. The median sizes of skull base craniectomy necessary for exposure of the anterior communicating artery complex and basilar tip were 3.24 cm2 and 4.62 cm2, respectively. The mean angles of surgical corridors to the anterior communicating artery complex and basilar tip were 11.4° and 14°, respectively. Although clip placement was feasible on the basilar artery and its branches, the associated perforating arteries were difficult to visualize, posing unexpected difficulty for safe clip application, with the exception of ventrolateral-pointing aneurysms.

CONCLUSIONS
The authors characterize the feasibility of endonasal endoscopic clip ligation of aneurysms involving the paraclinoid, anterior communicating, and basilar arteries and proximal control of the paraclival internal carotid artery. The endoscopic approach should be initially considered for nonruptured aneurysms involving the paraclinoid and anterior communicating arteries, as well as ventrolateral basilar trunk aneurysms. Clinical experience will be mandatory to determine the applicability of this approach in practice.
Mapping HIV Nursing Core Competencies in Entry-Level Education: A Pilot Project
Authors: Gagnon Marilou , Cator Stephany 
Published: July 2015

Background:
Many nursing specialty groups in Canada have developed their own entry-to-practice frameworks to inform nursing curricula. This article focuses on the framework of HIV/AIDS core competencies developed by the Canadian Association of Nurses in HIV/AIDS Care.

Method:
The goal of this pilot project was to map the courses offered in one entry-level program to assess the applicability of the framework as a tool to inform curriculum development.

Results:
This project highlighted competencies that were well covered in the current courses offered in the program, as well as existing gaps. To address these gaps, five areas of improvement were identified.

Conclusion:

The gaps and areas of improvement identified in this project are similar those identified in the nursing literature. As such, they reinforce the importance of incorporating education and training in entry-level programs with actual clinical experiences with and exposure to people living with HIV. [

The Nature of Clinical Judgment Development in Reflective Journals
Authors: Bussard Michelle 
Published: July 2015

Background:
Evaluating the development of clinical judgment after high-fidelity simulation (HFS) scenarios is essential for nurse educators to ensure that prelicensure nursing students are meeting course and curriculum outcomes.

Method:
This qualitative, interpretive description study reviewed the reflective journals of 30 prelicensure nursing students who participated in four progressive HFS scenarios during a medical–surgical nursing course to determine their levels of clinical judgment, using Lasater’s Clinical Judgment Rubric (LCJR).

Results:
Within journal one, 172 comments were identified as either beginning or developing in clinical judgment, whereas 52 comments were identified as such within journal four. In journal one, 65 comments were identified as accomplished or exemplary in clinical judgment, whereas 170 comments were identified as such within journal four.

Conclusion:

This study indicated that evaluating reflective journals using the LCJR is an effective method for ensuring that course and curriculum outcomes are met after prelicensure nursing students participate in HFS scenarios. [

Synovial sarcoma (SS) is the fourth most common type of soft tissue sarcoma, following malignant fibrous histiocytoma, liposarcoma, and rhabdomyosarcoma. It usually occurs in the extremities near the large joints of middle-aged patients. We describe a case of synovial sarcoma of the anterior abdominal wall (SSAW) in an adolescent girl and undertake a review of the literature.
“Honor” in Rhodes: Dio Chrysostom’s Thirty-First Oration
Authors: Bailey C. 
Published: July 2015

Abstract
This article argues that Dio Chrysostom’s thirty-first Oration offers a commentary on the condition of the Greek polis in a Roman world. Dio addresses the practice of re-using statues in order to show the role that the past plays in contemporary constructions of identity. Statues honoring past benefactors enable present citizens, and therefore Rhodes, to compete with those past benefactors and to live up to their full potential. Dio shows that it is a failure to contend with past benefactors that threatens the ability of the polis to be a polis.
Naples and the Landscape of Virgilian otium in the Carmina Bucolica of Petrarch and Boccaccio
Authors: Fielding Ian 
Published: July 2015

Abstract
This article explains how Virgil’s traditional association with Naples inspired the fourteenth-century humanist poets Francesco Petrarca and Giovanni Boccaccio to set their own Virgilian eclogues in the same city. Petrarch began his Bucolicum Carmen by composing an allegorical eclogue about the death of his patron Robert of Anjou, the King of Naples; and in imitation of this poem, his admiring friend Boccaccio later wrote a series of Neapolitan eclogues depicting the events that followed Robert’s death. As Petrarch and Boccaccio each had different relationships with Naples, it will be shown that the city represents their respective ideals of poetic otium.
Interstitial Lung Diseases That Are Difficult to Classify: A Review of Bronchiolocentric Interstitial Lung Disease
Authors: Virk Renu K. , Fraire Armando E. 
Published: July 2015

ContextIdiopathic bronchiolocentric interstitial pneumonia, airway-centered interstitial fibrosis, centrilobular fibrosis, and bronchiolitis interstitial pneumonia are increasingly recognized histopathologic variants of idiopathic interstitial pneumonia that are difficult to fit within existing classification schemes.ObjectiveTo review and analyze the appropriate literature that describes the spectrum of histopathologic changes in these conditions, in an effort to ascertain similarities as well as their differences. In addition, we examined associations with hypersensitivity, cigarette smoking, and survival data.Data SourcesRelevant and peer-reviewed literature indexed in PubMed (National Library of Medicine) coupled with experience gained by review of personal cases with appropriate histopathology constitute the basis of this study.ConclusionsAs anticipated, the common link among the above-cited conditions is their bronchiolocentricity, with a predominance of either fibrosis or inflammation. Clear-cut associations with hypersensitivity or cigarette smoking are not evident in this study. The airway-centered interstitial fibrosis variant of bronchiolocentric interstitial lung disease appears to have a poor outcome.

Published: July 2015

ContextHemolysis is an important clinical laboratory quality attribute that influences result reliability.ObjectiveTo determine hemolysis identification and rejection practices occurring in clinical laboratories.DesignWe used the College of American Pathologists Survey program to distribute a Q-Probes–type questionnaire about hemolysis practices to Chemistry Survey participants.ResultsOf 3495 participants sent the questionnaire, 846 (24%) responded. In 71% of 772 laboratories, the hemolysis rate was less than 3.0%, whereas in 5%, it was 6.0% or greater. A visual scale, an instrument scale, and combination of visual and instrument scales were used to identify hemolysis in 48%, 11%, and 41% of laboratories, respectively. A picture of the hemolysis level was used as an aid to technologists' visual interpretation of hemolysis levels in 40% of laboratories. In 7.0% of laboratories, all hemolyzed specimens were rejected; in 4% of laboratories, no hemolyzed specimens were rejected; and in 88% of laboratories, some specimens were rejected depending on hemolysis levels. Participants used 69 different terms to describe hemolysis scales, with 21 terms used in more than 10 laboratories. Slight and moderate were the terms used most commonly. Of 16 different cutoffs used to reject hemolyzed specimens, moderate was the most common, occurring in 30% of laboratories. For whole blood electrolyte measurements performed in 86 laboratories, 57% did not evaluate the presence of hemolysis, but for those that did, the most common practice in 21 laboratories (24%) was centrifuging and visually determining the presence of hemolysis in all specimens.ConclusionsHemolysis practices vary widely. Standard assessment and consistent reporting are the first steps in reducing interlaboratory variability among results.
The So-called Short-Fiber Controversy: Literature Review and Critical Analysis
Authors: Roggli Victor L. 
Published: July 2015

Context
Numerous articles in the scientific literature indicate that pathogenic fibers with respect to asbestos-related diseases are those that exceed 5 μm in length. Nonetheless, some authors have expressed concerns regarding pathogenicity of shorter fibers.

Objective
To review the scientific evidence regarding pathogenicity (or lack thereof) of fibers less than or equal to 5 μm in length, with particular attention to publications indicating that such fibers might be hazardous.

Data Sources
The scientific literature was reviewed for experimental animal studies and human studies that address the role of fiber size in causation of disease. Sources included original studies, as well as review articles related to the topic.

Conclusions
Experimental animal studies involving inhalation of fibers have demonstrated that fibers greater than 5 μm in length are associated with both pulmonary fibrosis (ie, asbestosis) and malignancies (carcinoma of the lung and mesothelioma). There is no convincing evidence for a pathogenic effect for fibers that are 5 μm or less in length. Fiber analyses of human lung tissue samples provide further support for pathogenicity of long fibers, particularly the more biopersistent amphibole fibers. Similar observations have been reported for nonasbestos mineral fibers. Concerns expressed by some authors (eg, the greater abundance of short fibers) do not alter these conclusions. Similarly, in vitro studies demonstrating biological activity of short fibers do not override inhalational studies of whole animals or the epidemiological findings in humans.
Complexity in salt marsh circulation for a semienclosed basin

Published: July 2015

AbstractThe fine details of overmarsh circulation remain largely unexplored and yet they are typically assumed to control many attributes of salt marsh material cycling, transport, and accretion. We characterized the spatial and temporal variability in overmarsh circulation at a 2 km2 Georgia, USA, salt marsh using field observations, dye tracer, and numerical simulations. The marsh bathymetry was created with a high‐precision Global Positioning System survey that details the geomorphic structure of intertidal creeks and salt marsh platform features greater than about 1 m in width. We assessed flow path dynamics at four spatial scales ranging from 1 m to 1000 m. Results show the development and decay of simultaneous flow divergence and convergence, concentrated flow and large‐scale rotational flow, and strong differences between flood and ebb pathways. This current complexity is set by submergence and emergence of subtle salt marsh platform geomorphic structure, and it highlights the role of topography in system‐wide flow processes.
Changes in seismic velocity during the first 14 months of the 2004–2008 eruption of Mount St. Helens, Washington

Published: July 2015

AbstractMount St. Helens began erupting in late 2004 following an 18 year quiescence. Swarms of repeating earthquakes accompanied the extrusion of a mostly solid dacite dome over the next 4 years. In some cases the waveforms from these earthquakes evolved slowly, likely reflecting changes in the properties of the volcano that affect seismic wave propagation. We use coda‐wave interferometry to quantify small changes in seismic velocity structure (usually <1%) between two similar earthquakes and employed waveforms from several hundred families of repeating earthquakes together to create a continuous function of velocity change observed at permanent stations operated within 20 km of the volcano. The high rate of earthquakes allowed tracking of velocity changes on an hourly time scale. Changes in velocity were largest near the newly extruding dome and likely related to shallow deformation as magma first worked its way to the surface. We found strong correlation between velocity changes and the inverse of real‐time seismic amplitude measurements during the first 3 weeks of activity, suggesting that fluctuations of pressure in the shallow subsurface may have driven both seismicity and velocity changes. Velocity changes during the remainder of the eruption likely result from a complex interplay of multiple effects and are not well explained by any single factor alone, highlighting the need for complementary geophysical data when interpreting velocity changes.
Last glacial maximum radiative forcing from mineral dust aerosols in an Earth system model

Published: July 2015

AbstractThe mineral dust cycle in preindustrial (PI) and Last Glacial Maximum (LGM) simulations with the Coupled Model Intercomparison Project Phase 5 model Hadley Centre Global Environment Model 2‐Atmosphere (HadGEM2‐A) is evaluated. The modeled global dust cycle is enhanced at the LGM, with larger emissions in the Southern Hemisphere, consistent with some previous studies. Two different dust uplift schemes within HadGEM2 both show a similar LGM/PI increase in total emissions (60% and 80%) and global loading (100% and 75%), but there is a factor of 3 difference in the top of the atmosphere net LGM‐PI direct radiative forcing (−1.2 W m−2 and −0.4 W m−2, respectively). This forcing is dominated by the short‐wave effects in both schemes. Recent reconstructions of dust deposition fluxes suggest that the LGM increase is overestimated in the Southern Atlantic and underestimated over east Antarctica. The LGM dust deposition reconstructions do not strongly discern between these two dust schemes because deposition is dominated by larger (2–6 μm diameter) particles for which the two schemes show similar loading in both time periods. The model with larger radiative forcing shows a larger relative emissions increase of smaller particles. This is because of the size‐dependent friction velocity emission threshold and different size distribution of the soil source particles compared with the second scheme. Size dependence of the threshold velocity is consistent with the theory of saltation, implying that the model with larger radiative forcing is more realistic. However, the large difference in radiative forcing between the two schemes highlights the size distribution at emission as a major uncertainty in predicting the climatic effects of dust cycle changes.
