Background: Dohi's Reticulated Acropigmentation is a rare autosomal dominant genodermatosis with high penetrance, characterized by small, irregular, hypo and hyperpigmented macules on the dorsal surface of the distal extremities.
Case: The authors report a case of Dohi’s Reticulated Acropigmentation in a 61 years old female patient. The patient complained of spots on hands, feet and posteriorly face involvement since she was 7 years old.
Conclusion: Dohi's Reticulated Acropigmentation is a rare clinical condition, which usually appear in childhood and commonly interrupt their onset before adolescence. The diagnosis is based on clinical data, physical examination and histopathological findings. The treatment is unsatisfactory and still no therapy is proposed.
Facial Vein Variation: A Cadaveric Study
Authors: Ferreira Arquez Humberto 
Published: January 2018

Background: The veins of the head and neck have a complex developmental pattern which predisposes them to variations in formation and drainage. Superficial veins of the head and neck are utilized for central venous cannulation, oral reconstruction and parenteral nutrition in debilitated patients. Clinical and sonological examinations of these veins may provide clues toward underlying cardiac pathology.
Aims: The aim of the present study was to describe anatomical variation and determined the position of the facial vein in relation to neighboring structures.
Methods and Findings: Head and neck region were carefully dissected as per standard dissection procedure, studied serially during the years 2013-2017 in 16 males and 2 females, i.e. 36 sides, embalmed adults cadavers with different age group, in the laboratory of Morphology of the University of Pamplona. In 34 sides (94.5 %) of the cases the facial vein (FV) terminated into the internal jugular vein via the common facial vein (CFV) as per standard anatomic description. The facial vein on two sides (5.5 %) was found to drain into the external jugular vein with different degree of angulations and variable distance from the angle of the mandible. On the right side, the facial vein was draining into external jugular vein (EJV), 63.6 mm below the angle of the mandible. On the left side, the facial vein was draining into EJV, 42.4 mm below the angle of the mandible. The length of the neck was 137.8 mm. The mean distance of the superior and inferior labial veins, deep facial vein, and angular vein from the inferior orbital margin was 41.89 ± 3.01, 52.31 ± 3.72, 26.85 ± 3.55 and 6.25 ± 0.65 mm, respectively.
Conclusion: A sound knowledge on variation of the course and termination of facial vein is very useful for oral and maxillofacial surgeons, plastic surgeons, otorrhinologists and radiologists, is essentially important in the clinical examination and surgical procedures of the head and neck region.
Unusual Combination Of Vascular Variations In The Retroperitoneal Region. A Morphological Study
Authors: Ferreira Arquez Humberto 
Published: January 2018

Background: Blood supply of kidney and gonads is characterized by the presence of variations, which are usually silent and unnoticed until they are found by retroperitoneal surgery, radiologic examination or necropsy. Multiple renal vessels are no longer relative contraindication for laparoscopic donor nephrectomy, however of their presence may help avoid possible complication on a patient with these variations. The purpose of this morphological study was to analyze the frequency of supernumerary renal and testicular vessels and describe an unusual combination of vascular variations in the retroperitoneal region.
Methods and Findings: A total of 18 cadavers with different age group and 10 visceral blocks were used for the study in the Morphology Laboratory of the University of Pamplona. Multiple anatomical variations bilateral of testicular vessels and renal were found during routine dissection in a 65-year-old male cadaver. The variations found were: bilateral presence of three renal arteries and three renal veins. The three left renal arteries are divided and gave rise to seven branches: the left main renal artery originates two branches; the upper branch originates four branches and the lower branch originates one branch. Retro-aortic left renal vein. Three left testicular artery and double right testicular artery all originating from accessory renal arteries.
Conclusions: Awareness of renal and testicular vessels anomalies is essential for decreasing the rate of accidental injuries in surgical procedures in the retroperitoneal region as well as aid in diagnosis of diseases associated with vascular variation in the posterior abdomen. An understanding of the morphology of renal and testicular vessels is necessary in uroradiology, Doppler imaging and computed tomography studies.

Abstract
Atmospheric temperature and planetary gravity are thought to be the main parameters affecting cloud formation in giant exoplanet atmospheres. Recent attempts to understand cloud formation have explored wide regions of the equilibrium temperature-gravity parameter space. In this study, we instead compare the case of two giant planets with nearly identical equilibrium temperature (T
eq ∼ 1050 K) and gravity (g ∼ 10 m s−1). During HST Cycle 23, we collected WFC3/G141 observations of the two planets, WASP-67 b and HAT-P-38 b. HAT-P-38 b, with mass 0.42 M
J and radius 1.4 R
J, exhibits a relatively clear atmosphere with a clear detection of water. We refine the orbital period of this planet with new observations, obtaining P = 4.6403294 ± 0.0000055 days. WASP-67 b, with mass 0.27 M
J and radius 0.83 R
J, shows a more muted water absorption feature than that of HAT-P-38 b, indicating either a higher cloud deck in the atmosphere or a more metal-rich composition. The difference in the spectra supports the hypothesis that giant exoplanet atmospheres carry traces of their formation history. Future observations in the visible and mid-infrared are needed to probe the aerosol properties and constrain the evolutionary scenario of these planets.
Probing the Massive Star-forming Environment: A Multiwavelength Investigation of the Filamentary IRDC G333.73+0.37

Abstract
We present a multiwavelength study of the filamentary infrared dark cloud (IRDC) G333.73+0.37. The region contains two distinct mid-infrared sources S1 and S2 connected by dark lanes of gas and dust. Cold dust emission from the IRDC is detected at seven wavelength bands, and we have identified 10 high-density clumps in the region. The physical properties of the clumps such as temperature (14.3–22.3 K) and mass (87–1530 M
⊙) are determined by fitting a modified blackbody to the spectral energy distribution of each clump between 160 μm and 1.2 mm. The total mass of the IRDC is estimated to be ∼4700 M
⊙. The molecular line emission toward S1 reveals signatures of protostellar activity. Low-frequency radio emission at 1300 and 610 MHz is detected toward S1 (shell-like) and S2 (compact morphology), confirming the presence of newly formed massive stars in the IRDC. Photometric analysis of near- and mid-infrared point sources unveils the young stellar object population associated with the cloud. Fragmentation analysis indicates that the filament is supercritical. We observe a velocity gradient along the filament, which is likely to be associated with accretion flows within the filament rather than rotation. Based on various age estimates obtained for objects in different evolutionary stages, we attempt to set a limit to the current age of this cloud.
Late-time Flattening of Type Ia Supernova Light Curves: Constraints from SN 2014J in M82

Abstract
The very nearby Type Ia supernova 2014J in M82 offers a rare opportunity to study the physics of thermonuclear supernovae at extremely late phases (≳800 days). Using the Hubble Space Telescope, we obtained 6 epochs of high-precision photometry for SN 2014J from 277 days to 1181 days past the B-band maximum light. The reprocessing of electrons and X-rays emitted by the radioactive decay chain

is needed to explain the significant flattening of both the F606W-band and the pseudo-bolometric light curves. The flattening confirms previous predictions that the late-time evolution of type Ia supernova luminosities requires additional energy input from the decay of 57Co. By assuming the F606W-band luminosity scales with the bolometric luminosity at ∼500 days after the B-band maximum light, a mass ratio

is required. This mass ratio is roughly ∼3 times the solar ratio and favors a progenitor white dwarf with a mass near the Chandrasekhar limit. A similar fit using the constructed pseudo-bolometric luminosity gives a mass ratio

. Astrometric tests based on the multi-epoch HST ACS/WFC images reveal no significant circumstellar light echoes in between 0.3 and 100 pc from the supernova.
Mapping Excitation in the Inner Regions of the Planetary Nebula NGC 5189 Using HST WFC3 Imaging

Published: January 2018

Abstract
The planetary nebula (PN) NGC 5189 around a Wolf–Rayet [WO] central star demonstrates one of the most remarkable complex morphologies among PNe with many multiscale structures, showing evidence of multiple outbursts from an asymptotic giant branch (AGB) progenitor. In this study, we use multiwavelength Hubble Space Telescope Wide Field Camera 3 observations to study the morphology of the inner 0.3 pc × 0.2 pc region surrounding the central binary that appears to be a relic of a more recent outburst of the progenitor AGB star. We applied diagnostic diagrams based on emission-line ratios of Hα
λ6563, [O iii] λ5007, and [S ii]

6716,6731 images to identify the location and morphology of low-ionization structures within the inner nebula. We distinguished two inner, low-ionization envelopes from the ionized gas, within a radius of 55 arcsec (∼0.15 pc) extending from the central star: a large envelope expanding toward the northeast, and its smaller counterpart envelope in the opposite direction toward the southwest of the nebula. These low-ionization envelopes are surrounded by a highly ionized gaseous environment. We believe that these low-ionization expanding envelopes are a result of a powerful outburst from the post-AGB star that created shocked wind regions as they propagate through the previously expelled material along a symmetric axis. Our diagnostic mapping using high-angular resolution line-emission imaging can provide a novel approach to detection of low-ionization regions in other PNe, especially those showing a complex multiscale morphology.
Innocent Bystanders: Orbital Dynamics of Exomoons During Planet–Planet Scattering

Published: January 2018

Abstract
Planet–planet scattering is the leading mechanism to explain the broad eccentricity distribution of observed giant exoplanets. Here we study the orbital stability of primordial giant planet moons in this scenario. We use N-body simulations including realistic oblateness and evolving spin evolution for the giant planets. We find that the vast majority (∼80%–90% across all our simulations) of orbital parameter space for moons is destabilized. There is a strong radial dependence, as moons past

are systematically removed. Closer-in moons on Galilean-moon-like orbits (<0.04 R
Hill) have a good (∼20%–40%) chance of survival. Destabilized moons may undergo a collision with the star or a planet, be ejected from the system, be captured by another planet, be ejected but still orbiting its free-floating host planet, or survive on heliocentric orbits as “planets.” The survival rate of moons increases with the host planet mass but is independent of the planet’s final (post-scattering) orbits. Based on our simulations, we predict the existence of an abundant galactic population of free-floating (former) moons.

Authors: Freedman Jane 
Published: January 2018

Les femmes sont de plus en plus nombreuses parmi les réfugiés qui tentent de rejoindre l’Europe pendant la « crise » actuelle. Cet article analysera les insécurités et les violences spécifiques aux femmes réfugiées. Insécurités qui sont souvent les conséquences directes des politiques européennes de « sécurité » et de fermeture des frontières. En se basant sur des entretiens et des observations dans différents endroits sur les routes migratoires, nous analyserons les expériences des hommes et des femmes réfugiés, en montrant les impacts différenciés des politiques migratoires et des représentations genrées et racialisées des réfugiés.
Le genre dans l’« Intifada des couteaux » : l’évolution de la place des femmes dans la lutte armée palestinienne
Authors: Marteu Élisabeth 
Published: January 2018

Depuis l’automne 2015, les espaces israélo-palestiniens sont traversés par une vague inédite de violences anti-israéliennes, le plus souvent individuelles, spontanées et non politisées. De nombreuses jeunes femmes, parfois mineures, ont pris part à des attaques au couteau, qui ont relancé les débats tant académiques que politiques sur le genre de la violence armée en Palestine. L’analyse de l’évolution de la participation des femmes à la lutte nationale palestinienne permet de souligner la singularité des dernières attaques que beaucoup qualifient aujourd’hui de suicides. A la portée de tous-tes, elles ne dépendent plus d’un encadrement logistique masculin et collectif. Elles traduisent l’usage indifférencié par les femmes et les hommes d’armes équivalentes pour exprimer leur frustration tant personnelle que nationale.
S’organiser au maquis comme à la ville
Authors: Guillemet Sarah 
Published: January 2018

Si les bataillons de femmes kurdes en armes ont fait la une des médias internationaux depuis la prise de Kobanê en 2014 par Daesh, cette forme d’organisation politique militarisée n’a pas été un acquis automatique au sein des organisations kurdes. Cet article propose ainsi d’étudier l’organisation en non-mixité des combattantes kurdes comme un outil de subjectivation politique. Il revient d’abord sur l’articulation progressive des rapports sociaux de sexe aux projets politiques révolutionnaires de deux partis de guérilla kurdes, le Komala et le Parti des Travailleurs du Kurdistan (PKK). Il présente ensuite l’évolution des systèmes d’organisation des genres au sein de ces deux partis, au regard des pratiques des combattantes depuis le début des luttes armées. Puis, il montre comment l’organisation en non-mixité des femmes kurdes a permis le passage d’une sororité combattante à une sororité résistante, redéfinissant les subjectivités, et les formes et espaces d’engagements tant dans la lutte armée que dans les mouvements civils.
Résistances des mouvements féministes en Turquie face à la violence extrême de guerre (des années 1980 à aujourd’hui)
Authors: Selek Pinar 
Published: January 2018

L’examen de l’histoire du mouvement féministe en Turquie procure maintes opportunités de comprendre que la contestation n’est pas seulement déterminée par le contexte politique. Comment les mouvements contestataires, malgré la répression, co-construisent les contextes pour résister ? En 1980, un nouveau cycle de contestation est né et a entraîné plusieurs innovations dans la construction du répertoire de l’espace militant en Turquie et dans les modalités d’organisation et d’action. Le mouvement féministe a joué un rôle déterminant dans ce processus en s’attaquant aux différents aspects de la domination masculine.
Quantifying the Effect of Data Quality on the Validity of an eMeasure

Published: January 2018

Objective The objective of this study was to demonstrate the utility of a healthcare data quality framework by using it to measure the impact of synthetic data quality issues on the validity of an eMeasure (CMS178—urinary catheter removal after surgery).
Methods Data quality issues were artificially created by systematically degrading the underlying quality of EHR data using two methods: independent and correlated degradation. A linear model that describes the change in the events included in the eMeasure quantifies the impact of each data quality issue.
Results Catheter duration had the most impact on the CMS178 eMeasure with every 1% reduction in data quality causing a 1.21% increase in the number of missing events. For birth date and admission type, every 1% reduction in data quality resulted in a 1% increase in missing events.
Conclusion This research demonstrated that the impact of data quality issues can be quantified using a generalized process and that the CMS178 eMeasure, as currently defined, may not measure how well an organization is meeting the intended best practice goal. Secondary use of EHR data is warranted only if the data are of sufficient quality. The assessment approach described in this study demonstrates how the impact of data quality issues on an eMeasure can be quantified and the approach can be generalized for other data analysis tasks. Healthcare organizations can prioritize data quality improvement efforts to focus on the areas that will have the most impact on validity and assess whether the values that are reported should be trusted.
Better Usability and Technical Stability Could Lead to Better Work-Related Well-Being among Physicians

Published: January 2018

Background and Objective Finnish physicians have been increasingly dissatisfied with poor usability of the electronic patient record (EPR) systems, which they have identified as an overload factor in their work. Our aim is to specify which factors in EPRs are associated with work-related well-being of physicians.
Methods A web-based questionnaire was sent to Finnish physicians younger than 65 years; the responses (n = 3,781) represent one-fourth of these. This was a repetition of a survey in 2010, where this questionnaire was used for the first time. In addition to statements assessing usability, there were questions measuring time pressure and job control. The relation between usability and work well-being was investigated with hierarchical multivariate regression analyses: With time pressure and job control as dependent variables, EPR usability assessments and physicians' background information were used as independent variables.
Results In the multivariate analyses, technical problems that are often experienced in the EPR were related to higher time pressure and lower job control. Active participation in the development of the EPR system was related to stronger time pressure and stronger job control. In addition, use of several systems daily and the experience of time-consuming documentation of patient information for statistical purposes (billing, national registries, and reporting) were related to higher time pressure, while those with longer experience with the EPR system and those experiencing easy-to-read nursing records reported higher job control.
Conclusion To relieve time pressure and increase sense of job control experienced by physicians, usability, integrations, and stability of the EPR systems should be improved: fewer login procedures, easier readability of nursing records, and decreased need for separate documentation for statistical purposes. Physician participation in the EPR development would increase the feeling of job control, but would add the time pressure. Hence, time for developmental work should be arranged.
Health IT Usability Focus Section: Data Use and Navigation Patterns among Medical ICU Clinicians during Electronic Chart Review
Authors: Nolan Matthew , Siwani Rizwan , Helmi Haytham , Pickering Brian , Moreno-Franco Pablo , Herasevich Vitaly 
Published: January 2018

Background A detailed understanding of electronic health record (EHR) workflow patterns and information use is necessary to inform user-centered design of critical care information systems. While developing a longitudinal medical record visualization tool to facilitate electronic chart review (ECR) for medical intensive care unit (MICU) clinicians, we found inadequate research on clinician–EHR interactions.
Objective We systematically studied EHR information use and workflow among MICU clinicians to determine the optimal selection and display of core data for a revised EHR interface.
Methods We conducted a direct observational study of MICU clinicians performing ECR for unfamiliar patients during their routine daily practice at an academic medical center. Using a customized manual data collection instrument, we unobtrusively recorded the content and sequence of EHR data reviewed by clinicians.
Results We performed 32 ECR observations among 24 clinicians. The median (interquartile range [IQR]) chart review duration was 9.2 (7.3–14.7) minutes, with the largest time spent reviewing clinical notes (44.4%), laboratories (13.3%), imaging studies (11.7%), and searching/scrolling (9.4%). Historical vital sign and intake/output data were never viewed in 31% and 59% of observations, respectively. Clinical notes and diagnostic reports were browsed ≥10 years in time for 60% of ECR sessions. Clinicians viewed a median of 7 clinical notes, 2.5 imaging studies, and 1.5 diagnostic studies, typically referencing a select few subtypes. Clinicians browsed a median (IQR) of 26.5 (22.5–37.25) data screens to complete their ECR, demonstrating high variability in navigation patterns and frequent back-and-forth switching between screens. Nonetheless, 47% of ECRs begin with review of clinical notes, which were also the most common navigation destination.
Conclusion Electronic chart review centers around the viewing of clinical notes among MICU clinicians. Convoluted workflows and prolonged searching activities indicate room for system improvement. Using study findings, specific design recommendations to enhance usability for critical care information systems are provided.
