Abstract. Surface snow density is an important variable for the surface mass balance and energy budget. It evolves according to meteorological conditions, in particular snowfall, wind and temperature, but the physical processes governing atmospheric influence on snow are not fully understood. A reason is that no systematic observation is available on a continent scale. Here, we use the passive microwave observations from AMSR-E satellite to retrieve the surface snow density at Dome C in the East Antarctic Plateau. The retrieval method is based on the difference of surface reflections between horizontally- and vertically-polarised brightness temperatures at 37 GHz, highlighted by the computation of the polarisation ratio, which is related to surface snow density. The relationship has been obtained with a microwave emission radiative transfer model (DMRT-ML). The retrieved density, representative of the topmost 3 centimetres of the snowpack, compares well with in situ measurements. The difference between mean in situ measurements and mean retrieved density is 26.2 kg m−3, which is within typical in situ measurement uncertainties. We apply the retrieval method to derive the time series over the period 2002–2011. The results show a marked and persistent pluri-annual decrease of about 10 kg m−3 yr−1, in addition to atmosphere-related seasonal, weekly and daily density variations. This trend is confirmed by independent active microwave observations from ENVISAT and QuickSCAT satellites though the link to the density is more difficult to establish. However, no related pluri-annual changes in meteorological conditions has been found to explain such trend in snow density. Further work concern the extension of the method at the continent scale.
Christianity: A Phenomenological Approach?
Authors: Henry Michel
Published: December 2018

Here I investigate the possibility of a phenomenological approach to Christianity, with the understanding that this would not be a matter of proposing an interpretation, but that such an “approach” would be able to lead directly to the heart of Christianity. I will say immediately that a phenomenology that would be able to undertake such a task is not the historical phenomenology that was born with Husserl. Only an ideal phenomenology that would become what is required would be able to respond to our investigation. This ideal phenomenology is a phenomenology of life.
From Necrotic to Apoptotic Debt: Using Kristeva to Think Differently about Puerto Rico’s Bankruptcy
Authors: Trigo Benigno
Published: December 2018

Without the maternal hold, without its herethical ethics and sublimation, without the stability (fragile as it may be) that this hold can bring, we are melancholically or defensively driven to commit the most heinous acts of atrocity and violence in the name of eternal life, development, and progress. For the most part, Kristeva has described the combination of personal loss and social, cultural, and historical pressures brought to bear on the vexed (but ultimately successful) sublimation of the maternal hold by artists like Giovanni Bellini. More recently, however, her attention has turned to other contemporary examples, in particular, Max Beckmann whose works, she claims, sublimate the loss of the maternal hold itself. They are examples of a Sacred Family, a Pietà, or a Dormition that have undergone a radical transformation. They are representations of a society, a culture, indeed a world, that is losing its maternal hold; a world that is losing both its herethical ethics, and the capacity to sublimate its apoptotic inheritance. Following Kristeva, I will put Eduardo Lalo’s book of poems and drawings Necrópolis (2014) in a tradition of representation of the maternal hold that is close to a thousand years old. This tradition goes from the confrontation with nothingness in Theophane the Greek’s Dormition (1392) to the modern matricide represented in Pablo Picasso’s Maternity Apple (1971).
Time and Crisis: Questions for Psychoanalysis and Race
Authors: Spillers Hortense
Published: December 2018

In the triumvirate of personalities and motives—from Wright and Baldwin to Coates—we encounter the essential elements of the “crisis” that configures black passage in the New World. These lines of kinship, both consanguineous and ineffable, travelling from father to son, from uncle to nephew, from one generation to the next, lend us a figurative rhythm that grasps the notion of the processional—the traversal of time and space that remains fundamentally mysterious, just as we can put our finger directly on the problem—black life is still as endangered and precarious as it ever was. If one regards such passage as a “crisis,” then it is precisely because it is riddled with turning points, sudden ruts and rifts in the road when the way seemed smooth and clear—those moments when decisions must be made—and from that perspective, African-American cultural apprenticeship offers, by definition, crisis not as a state of exception, but rather, as a steady state, given historical pressures that bear in on it and that become, as a result, intramural pressures. What I wish to do in these remarks is to clarify one of the questions engendered by this predicament, and that is to say, the riddle of identity and how it matters, but even more than an inquiry into the identitarian, I am searching for a protocol through intramural space.
The Psychic Life: A Life in Time: Psychoanalysis and Culture
Authors: Kristeva Julia
Published: December 2018

Last year I published an autobiographical text in the form of interviews with a young psychologist entitled Je me voyage. The title’s neologism gives a nod to my foreign status in the French language which has largely determined my psychosexual positioning in research and in writing; the psychic experience has been central to my life’s trajectory (which I will not elaborate on here.)  In my familial context, culture constituted a world that made life liveable —and I experienced life, due to the importance accorded to language, as survival, as an intimate resistance and an inherent creativity in social time.

Analysing Media Discourse: The Case of Conceptual Metaphors in Football News Headlines in English and Arabic
Authors: Alzawaydeh Rashid , Alghazo Sharif
Published: December 2018

This study explores the use of conceptual metaphors in football news headlines in English and Arabic. It aims to find the similarities and/or differences between English and Arabic in respect of the identified metaphorical concepts. The corpus of the study consists of two samples: one in Arabic (n = 200) and another in English (n = 200). The metaphor identification procedure of Pragglejaz Group (2007) was used to identify the metaphors in the corpus. Two native speakers of Arabic and two native speakers of English assessed the researchers’ categorization and classification in the two samples. The findings revealed that the most predominant conceptual metaphor used in the English and Arabic headlines was FOOTBALL IS WAR and that there is a great similarity between the two languages in respect of the use of conceptual metaphors. The findings also indicate that the Arabic headlines tended to include a more metaphorical tune than the English ones. The study concludes with some implications for a better understanding of the connection between the two languages and their respective cultures.
Semi-fortified Palatial Complexes in Central Asia: New Work at the Great Kyz Kala, Merv, Turkmenistan

Published: December 2018

Within Central Asia there is an unusual group of earthen buildings (köshks), usually constructed on raised platforms, with vertical engaged columns forming iconic ‘corrugations’ on the exterior walls. The complexes are semi-fortified, with a second storey entrance, and often with asymmetrical ranges of rooms around an internal courtyard. Little systematic archaeological work has taken place on these monuments, which have mainly been studied as relatively eroded standing structures. However, recent work at the Great Kyz Kala at Merv, Turkmenistan, the largest surviving monumental köshk in Central Asia, has provided more details of construction and use. The excavations suggest that this complex was constructed in the 8th/9thcentury CE, with well-appointed rooms on the second storey, including a large hall, and functional rooms and storage spaces around a courtyard on the lower floor. The complex was set within an enclosure, containing gardens and possibly ancillary buildings. This particular köshk may have acted as an elite palatial suburban residence, perhaps for the governor of Merv.
The complications associated with guidewire use in spine surgeries involving pedicle screw placement: A comprehensive literature review

Published: December 2018

Guidewires (Kirschner or “K” wires) are often required during minimally invasive spine surgery to facilitate percutaneous pedicle screw placement. The use of guidewires involves a multi-step process that carries the risk of complications and their associated consequences. To date, the reporting of such information has been limited, and the literature has not been thoroughly evaluated. The objective of this study was to conduct a narrative review and assess the burden associated with guidewire use in spine surgeries. Databases searched included PubMed and Embase between the years of 1988 and 2017. In addition to databases, recent data from relevant trade journals were hand-searched. Inclusion criteria were broad to avoid potential exclusion of relevant publications. In total, 31 articles were included. This review found that the risk of complications associated with guidewire use in spine procedures ranged from 0.4% to 14.8%. Complication types included guidewire fracture, cerebrospinal fluid leakage, post-operative ileus, infection, and other spinal hardware failure (e.g., pedicle screw pull-out). Causes of complications typically included breakage and migration of the guidewire (metal fatigue), inexperience with guidewire use, or lack of tactile or visual feedback. Specific surgery types or patient populations may be more susceptible to guidewire-related complications (e.g., L5-S1 level operations). Complications associated with guidewire use may also lead to healthcare resource utilization, including additional operating time, radiation exposure, and re-operations. Solutions to help minimize the risk of such complications and associated consequences are required.
The Chronicler's Code: The Rise and Fall of Judah's Army in the Book of Chronicles
Authors: Klein Neriah
Published: December 2018

This article focuses on the numbers given in the book of Chronicles for the armies of the Judean kings, with an emphasis on the sequence of the first four kings of Judah. It argues that these numbers were inserted by the Chronicler according to a clear and systematic pattern. Specifically, they are used as a literary device to express a pattern of changes in royal power, in which power increased from the time of Rehoboam's reign until Jehoshaphat, before gradually decreasing until the reign of Ahaz.
Burt- Or Coleman-Type Rents, Or a Bit of Both? Knowledge Management Strategies in Suppliers’ Networks
Authors: Antonelli Gilda , Mollona Edoardo , Moschera Luigi
Published: December 2018

Nodal Enterprises (NEs) (Dyer & Nobeoka, 2000) create value by exploiting their position at the center of networks of supplier firms. In managing these networks of organizations, however, NEs face a dilemma: how much knowledge must be shared with partners in the value-chain? In this paper, we propose that knowledge sharing must be managed dynamically.

Building on selected applications of social network theory to clusters’ analysis (Kogut, 2000), we assume that NEs manage a combination of two types of rents when they share knowledge among their networked firms: “Coleman-type” and “Burt-type” rents. How the combination between the two dynamically unfolds is an unexplored issue. Using a computer simulation model, we explore robustness of alternative strategies of knowledge sharing among networked firms. Learning from our simulation experiments, we suggest a desired inter-temporal pattern of knowledge sharing and we show how the steady-state of knowledge-sharing depends counterintuitively on the speed at which knowledge leaks among the firms that are connected in the network.

The savanna of the northern Amazon of Brazil is an ecosystem that presents lakes and riparian of buriti (Mauritia flexuosa L.) in its landscape. Although these ecosystems are protected by law, they are subject to changes by anthropization in their surrounding areas. The soils of lakes and on the banks of the buriti riparian of the savanna of Boa Vista, Northern Amazonia, are hydromorphic and, although they are important ecosystems for the environmental sustainability, they are little studied. Thus, the purpose of this work was to characterize the chemical composition of these soils and relate the results to the type of anthropization. Samples were collected at the margins of five riparian and three lakes in the 0.0-0.1, 0.1-0.2, 0.2-0.3, 0.3-0.4, and 0.4-0.5 m depth layers. Soil samples, in each environment, were taken from three points equidistant at 100 m. For soil characterization, pH in water, H + Al, Al3+, P, K+, Mg2+, Ca2+, and total organic C (TOC) were determined. The soils of lakes and buriti riparian are of high acidity, low natural fertility, and high toxicity by Al. Buriti riparian presented the highest levels of TOC but were also the environments most susceptible to the effects of anthropization, in which Bom Intento presented values of available P from medium to high by the interference of agricultural activities.

Chia (Salvia hispanica L.) is an herbaceous annual plant considered a natural source of Omega 3 and 6 fatty acids, fiber, protein and antioxidants. However, the cultivation in Brazil is still recent and existing technical information and recommendations are limited, especially regarding to fertilization and sowing season. The present work had as objective to evaluate the effect doses application of phosphorus and sowing times over productive and reproductive parameters. The experiment was conducted in greenhouse conditions at Fazenda da Universidade Estadual de Maringa, Campus Umuarama. The soil used for the experiment is a typical Distrofic Red Latosoil, with sandy texture. The experimental design was entirely in factorial scheme 4 × 4 with three replications. Treatments were composed of four seeding seasons, at intervals of 15 days between one and another with four doses of P2O5 applied at seeding (0, 40, 80 and 120 kg ha-1, totalizing 48 plots units. It was evaluated the following parameters dry mass of root and shoot, grain yield, mass of 1,000 grains and oil content. There were no significant results both for phosphorus doses as for interaction in any of the variables evaluated. The treatment seeding times (E) differed statistically only for grain yield.

The demand for healthier foods has been increasing worldwide. Associated with this trend, it is crucial to optimize the use of inputs for ensuring the sustainability of production. The fruits of tomato are important sources of minerals, vitamins, and especially of carotenoids such as the lycopene. This carotenoid plays biological activities that are crucial such as the antioxidant function, besides its proven action in the prevention of cancers and degenerative diseases. The irrigation seems to play a fundamental role in the biosynthesis of lycopene. Thus, it is fundamental to establish levels of irrigation that might provide higher content of lycopene, productivity, and efficiency in the use of water in the production of tomato. The objective of this study was to establish adequate levels of irrigation for the obtainment of higher content of lycopene, productivity of fruits, and higher efficiency in the use of water in the production of salad tomato. For this, two experiments were carried in different cropping seasons. The treatments consisted of the application of four irrigation depths, corresponding to 50, 100, 150 and 200% of the tomato evapotranspiration. The estimates of maximum productivity corresponded to the application of the irrigation depth of 112% ETc, while the maximum content of lycopene and the higher efficiency in the use of water corresponded to 50% ETc. The irrigation depth of 100% ETc is recommended as the best irrigation depth to obtain higher content of lycopene, productivity, and efficiency in the use of water jointly.

Currently, sustainable practices combined with an efficient livestock can have benefits for farmers as observed in this study in which the animals themselves spread the seeds in the pasture in order to promote an addition of forage resources in the canopy. The objective of this study was to evaluate seed germination of three forage species [Avena strigosa Schreb (black oat), Calopogonium mucunoides (calopogonium) and Neonotonia wightii (perennial soybean)] following ingestion by cattle. The feces were collected from the animals at intervals of 6 hours up to 48 hours after the ingestion of the seeds. The feces were placed in beds in the field for further germination studies for the next 30, 60 and 90 days (post-planting periods). No difference (P > 0.05) was observed between the treatments species or between post-planting periods of the evaluation. For all the studied seeds, the germination was only verified in the time of up to 30 days after the placement of the feces in the field, where black oats obtained numerically the highest accumulated percentage (during 48 hours) with 10% of germinated seeds. It is concluded that the use of cattle as a disperser of forage seeds can help in the introduction of new forage in order to improve the production and the quality of the pastures. The moment of the cattle entrance in the pickets will depend on the forage species to be introduced and can vary from 6 to 12 hours after the intake of the seeds.

The change in the use of natural vegetation by annual or perennial crops, sugarcane and fast-growing forests causes changes in the biophysical variables, and these changes can be monitored by remote sensing. The objective of this work was to evaluate, on a temporal scale, the impacts of land use changes on biophysical variables in the county of Santa Helena de Goias-Goias/Brazil. Between the years of 2000 to 2015 areas were identified for agricultural crops 1 (annual crops), water, agricultural crops 2 (sugarcane), natural vegetation, pasture and urban areas. The MODIS (Moderate Resolution Spectroradiometer) sensor products were selected for study: MOD11A2-Surface temperature; MOD16A2-Real evapotranspiration, MOD13Q1-Enhanced Vegetation Index and rainfall data from TRMM (Tropical Rainfall Measuring Mission). The geographic coordinates referring to the land uses were inserted in the LAPIG platform, searching the information of the biophysical variables referring to the selected pixel. The impact of land use change was evaluated by calculating the weighted average through the quantitative classification of the areas. It is concluded for the period of study that the index of average vegetation of the county had increase. There was an increase in the evapotranspiration volume of the county from 28% from 2000 to 2013 and the average surface temperature of the county showed a reduction of 2 °C in the period from 2000 to 2015.

The (Parkia pendula (Willd.) Benth. ex Walp.) species most know as visgueiro is a native specie from the Amazon region, belongs to the family Fabaceae-mimosoideae and has been scientifically studied because it is used in landscape projects and the restoration of degraded areas. Intrinsic responses of this species due to water stress is still very superficial, lacking a larger scientific approach in nitrogen and oxidative parameters. For this, a greenhouse experiment was set up in the Federal Rural University of Amazon with seedlings, where they were submitted to water restriction. The experimental design was completely randomized in a 2 × 3 factorial design (control and water deficit, and three evaluation times), with 5 replications, totaling 30 experimental units. The results showed that the RWC reduced during the experiment from 73.5% to 52.99%, evidencing a lower amount of water in these plants. This condition caused the plants to respond positively to the increase of antioxidant enzymes (catalase, APX and SOD), making the plant defense system efficient. As well as for some variables of nitrogen metabolism. The results showed that the RWC reduced during the experiment from 73.5% to 52.99%, evidencing a lower amount of water in these plants.

Published: December 2018

Objective: Pathogens resistant to ≥3 antimicrobial agents are

referred to multi-drug resistant (MDR) pathogens. Although several antibiotics

are available, antibiotics with broader spectrum of activity is required. The

present study aimed to evaluate the in vitro susceptibility of minocycline

against Carbapenem resistant gram-negative bacilli and its concordance

sensitivity as compared to Tigecycline. Methods:

Non-repetitive, consecutive isolates carbapenem resistant gram-negative bacilli

including MDR Klebsiella pneumoniae (K. pneumoniae) and Acinetobacter spp. were used for evaluation using Epsilometer test

(E-test). The minimum inhibitory concentration (MIC) cut-off range for

minocycline was based on Clinical and Laboratory Standards Institute (CLSI,

2016) and the interpretation (sensitive<4, intermediate=8, resistant ≥16)

was considered valid for both, Enterobacteriaceae

and Acinetobacter. Concordance

susceptibility of minocycline was compared with that of tigecycline. Results:

Overall, 18 isolates from MDR Acinetobacter

spp., 20 isolates from MDR Enterspp.obacter spp. (18 E. coli isolates and 2 Enterobacter, undefined), and 63 isolates of

MDR Klebsiella spp. (58 K. pneumoniae

isolates and 5 Klebsiella isolates) were evaluated. In vitro, sensitivity of

minocycline was 50.0% (9/18) in Acinobacter species; 45.0% (9/20) in Enterobacter spp. and 36.5% (23/63) in

Klebsiella spp., respectively. Of the 101 isolates used, concordance between

tigecycline and minocycline was observed in 42 isolates (41.6%) and sensitivity

to both minocycline and tigecycline was observed in 12 isolates (28.6%). The

Cohen Kappa values showed that the overall concordance between tigecycline and

minocycline was 0.11 (non-slight agreement).

Conclusion: Minocycline is effective against all the three

carbapenem resistant gram-negative bacteria included in the study. J Microbiol Infect Dis 2018; 8(4):140-146.

To estimate the error intrinsic to these estimations, a series of synthetic spectra was constructed from the theoretical spectrum combined with random rrors, which were then used to obtain structure functions and ogive. The " estimation from spectra or structure functions presented a root mean square value of approximately 2% of the expected value of ", whereas the estimation from ogives had errors of approximately 1:3%. A correction factor is needed in the estimations using the ogive and the structure function in order to remove the bias caused by the finite Nyquest frequency. Due tothe smaller error, the ogive provides the best approach for indirect estimation of " in the atmospheric boundary layer.
Fluxos de CO2 em uma área de floresta tropical úmida na Amazônia Ocidental em um ano de El Niño

Published: December 2018

The objective this paper was to quantify the hourly variability of CO2 fluxes in the year of the El Niño, in 2015, in a tropical rain forest in the Western Amazon. Data of CO2 fluxes collected at 63.5 m height in a tower of the Large-Scale Biosphere–Atmosphere Experiment in Amazonia in the Jaru Biological Reserve, composed of the Open Ombrophilous forest, were analyzed. Data from the dry-wet period were used, which by convention, the negative and positive values indicate absorption and emission of CO2, respectively. The CO2 uptake in the forest had higher levels between 9:30 a.m. and 4:00 p.m., with mean values between -19 and -13 μmol m-2 s-1, however the peak absorption occurs at 1:00 p.m. with -30 μmol m-2 s-1, considering that at this time the sun's rays are most intense. In average, the Rebio Jaru absorbs more than the areas of the transition Amazonia-Cerrado, indicating that the physiological activities in Ombrophilous forest require a greater amount of carbon. The average daily behavior of CO2 fluxes showed higher concentrations of absorption during the day than emissions overnight, behaving as a carbon sink, corroborating the importance of the forest in assimilation of the atmospheric carbon.

In this study, the eddy-covariance technique was used to estimate the surface fluxes of carbon (CO2) and energy, in the latent (LE) and sensible (H) forms, over a native field ecosystem (pasture). The results show that the ecosystem in question presents a predominant seasonality in its ecological functioning, especially regarding the observations of the LE and CO2 fluxes, with carbon assimilation and evapotranspiration with maximum values during the summer. During the winter season observations point to a lower metabolic state of the ecosystem, with almost zero carbon assimilation (even a carbon source signal inversion) and the evapotranspiration rate falling to 60% of its value in the highest state metabolic activity.

This research aimed to present results about the mixing ratio and flux of monoterpenes at a forest region of the Brazilian Amazon. It was used micrometeorology instrumentation (using a Sonic Anemometer) and analytical chemistry by a Proton Transfer Reaction - Time of Flight - Mass Spectrometer, PTR-ToF-MS. The calibration of the spectrometer was performed regularly using a gravimetric mix of standard gas containing different masses of volatile organic compounds. The results showed average mixing ration of monoterpenes of 0.185 ppbv and maximum emission flux of 1.495 mg m-2 h-1. It was concluded that this region presented a significant emission of monoterpenes in relation to another tropical forest in central Amazonia, evidencing the needing to improve studies about atmospheric chemistry in different forests of the Amazon Basin.

The processes of land use and occupation generate interventions in the natural ecosystems making them susceptible to reactions, such as changes in the processes that govern water cycling, emphasizing the importance of monitoring the evapotranspiration behavior. In this sense, the objective of this study was to verify the applicability of the evaporation product originated by the MODIS sensor to a pasture area, from 2003 to 2010, at Fazenda Nossa Senhora in the municipality of Ouro Preto do Oeste - Rondônia. Were used evapotranspiration data from the MODIS (Terra / Aqua) sensor, estimated by MOD16 algorithm, and micrometeorological tower located in the pasture area, generated by eddy covariance system. It was verified that for ET Eddy x ET MOD16 (Quality control – QC 0/8) data set, ET MOD16 (QC 0/8) data showed evapotranspiration values above those of ET Eddy and with a greater amplitude. A linear correlation between the study datasets was not identified, however, seasonal variations are captured by product, showing good approximation with ET Eddy data, especially in the transition periods.
Minimum-cost numerical prediction system for wind power in Uruguay, with an assessment of the diurnal and seasonal cycles of its quality

Published: December 2018

This work presents the results of a numerical forecast system of minimum cost for the electric power generated by wind farms in Uruguay. By keeping at minimum levels both the computational costs and the complexity of the empirical corrections of the numerical results, we obtain a benchmark for the forecast skill of more complex forecast systems, that is easily available during their calibration stages and operative functioning. The work also aims to explore the diurnal and seasonal cycle of the forecasts quality. It is found that this simple forecast system produces very good results, albeit the dependencies of the forecast skill and errors respect to the season of the year and the time of the day are distinguishable. It is also found that it is necessary to take into account the diurnal and the seasonal cycles during the calibration of the empirical corrections. The good results of this simple technique might had been possible due to the relative smooth topography of Uruguay.

Two micrometeorological towers located in the experimental site of Pedras Altas in the region of Pampa Gaúcho were separated by a distance of about 500 m from each other, enabling a small scale horizontal variability, due to the complexity of the terrain. Such variability favors distinct contributions in the modes of flow. This work points out a relation between classes of maximum wind measured in the station of the top of the hill with obstructions provoked by the heterogeneity of the terrain. Through a spectral analysis it was possible to find encouraging results for future work, as the study shows a pertinent relation between non-turbulent low frequency motions with surface heterogeneity and how this implies in the horizontal and vertical turbulent velocity.

Introducción. La vacunación es la intervención en salud pública más efectiva de todos los tiempos, reduciendo las muertes y las morbilidades de múltiples enfermedades infecciosas. En muchas ocasiones la aplicación de las vacunas es retrasada por el temor a reacciones alérgicas, esto es frecuente entre los pacientes con alergia a huevo que requieren la vacuna triple viral.Objetivo. Evaluar la frecuencia de reacciones luego de la aplicación de la vacuna triple viral (rubeola-sarampión-parotiditis) en una población alérgica al huevo.Materiales y métodos. Estudio multi-centrico retrospectivo (2014-2016) que incluyó pacientes con alergia al huevo que acudieron a un centro de alergología y requerían la aplicación de la vacuna triple viral.Resultados. 94 pacientes cumplían los criterios de selección. 68,2% tuvieron síntomas cutáneos, 22,3% reacción anafiláctica, 5,3% síntomas gastrointestinales y 4,2% síntomas respiratorios con huevo. Todos los pacientes independientemente de la gravedad de su reacción con el huevo, recibieron la vacuna triple viral y en el 100% fue bien tolerada.Conclusión. Aunque la alergia al huevo es frecuente en la edad infantil, el riesgo de reacciones alérgicas durante la vacuna triple viral en esta población es similar al de la población general, por lo que no se debe diferir incluso en pacientes con antecedente de reacciones graves al huevo.

Introducción. Los factores de riesgo cardiovascular (FRCV) tienen su origen en la infancia. Existen estudios que muestran diferencias en la prevalencia de los FRCV en el área rural y urbana posiblemente asociadas a los estilos de vida.Objetivos. El presente estudio describe los FRCV identificados en niños de una población rural y una población urbana en Colombia.Materiales y métodos. Estudio de corte transversal realizado entre marzo y junio de 2013 en escolares de un área urbana y otra rural en Colombia. Se realizaron mediciones de peso, ta-lla, presión arterial, triglicéridos, glicemia y colesterol total en ayunas, y se aplicó una encues-ta alimentaria sobre actividad física y tabaquismo pasivo. Se evaluaron prevalencias de los FRCV con un IC95%.Resultados. 1055 escolares, 833 (urbanos), 222 (rurales), promedio de edad de 6.71 años. La prevalencia de FRCV en la población de estudio rural/urbano fue para sedentarismo 68.69%/90.16%, dieta no saludable 97.18%/95.44%, tabaquismo pasivo 11.16%/14.52%, obe-sidad 0%/5.64%, hipertensión arterial 6.31%/11.28%, diabetes 0%/0%, hipercolesterolemia 18.28/16.31%. El 99.15% de la población de estudio presentó al menos un FRCV, promedio área urbana de 3.14 (DE: 1.12), y rural 2.76 (DE: 1.1). Los niños con exceso de peso presen-taron mayor prevalencia de hipertensión arterial, 15,21%, y de sedentarismo, 90.69%, comparado con aquellos sin exceso de peso, 8,98 %, y 84,32% respectivamente.Conclusiones. Nuestros resultados evidencian una alta prevalencia de FRCV en niños, siendo mayor en el área urbana. Es necesario la implementación de estrategias en salud pú-blica adaptadas a la población rural y urbana.

Primary malignant melanoma of the esophagus (PMME) is a rare, aggressive, therapy-resistant malignant tumor arising from esophageal mucosal melanocytes. It has been reported that fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) has a clinical impact on PMME diagnosis; however, it remains unclear whether postoperative surveillance using FDG-PET/CT is useful for PMME patients. In this case study, FDG-PET/CT detected the recurrent tumors in their early stage after a curative resection of PMME. We report on a case of a 67-year-old Japanese male admitted to our hospital for the evaluation of polypoid tumors of the esophagogastric junction, which were diagnosed as PMME. He was treated with a curative resection by esophagectomy and 6 cycles of adjuvant chemotherapy of DAV (dacarbazine, nimustine, and vincristine). However, the PMME recurred 26 months after the surgery when surveillance FDG-PET/CT detected the recurrent tumors in their early stage. FDG-PET/CT may be useful to detect recurrence in the postoperative surveillance phase for PMME patients.
Perforated Diverticulitis of the Transverse Colon: An Unexpected Cause of Abdominal Pain During Preoperative Bowel Preparation
Authors: Shah N. A. , Ho Y. H.
Published: December 2018

Diverticulitis affecting the transverse colon is uncommon, with perforation being exceptionally rare. It is not usually considered in the differential diagnosis of a patient with acute abdominal pain. We report a case of nonspecific abdominal pain secondary to a perforated diverticulum in the transverse colon during preoperative bowel preparation. A 74-year-old Caucasian female had sudden onset abdominal pain and nausea with routine bowel preparation. This undifferentiated acute abdomen was suggestive of a bowel perforation, which was later confirmed by a computed tomography scan. Surgical exploration determined the location of the perforation in the transverse colon. We report an unusual presentation of preoperative abdominal pain during routine bowel preparation. It is extraordinarily uncommon to see rupture of a transverse colon diverticulum in a patient with sigmoid involvement, and bowel preparation as a cause of rupture has not been previously documented. Because perforation of a transverse colon diverticulum generally has a nonspecific clinical presentation, it should be considered in the differential diagnosis for a patient with known diverticular disease who has acute onset abdominal pain and signs of peritonism.
