An Electron Paramagnetic Resonance Spectroscopy Investigation of the Retention Mechanisms of Mn and Cu in the Nanopore Channels of Three Zeolite Minerals
Authors: Ferreira Daniel R. , Schulthess Cristian P. , Amonette James E. , Walter Eric D.
Published: February 2013

The adsorption mechanisms of divalent cations in zeolite nanopore channels can vary as a function of their pore dimensions. The nanopore inner-sphere enhancement (NISE) theory predicts that ions may dehydrate inside small nanopore channels in order to adsorb more closely to the mineral surface if the nanopore channel is sufficiently small. The results of an electron paramagnetic resonance (EPR) spectroscopy study of Mn and Cu adsorption on the zeolite minerals zeolite Y (large nanopores), ZSM-5 (intermediate nanopores), and mordenite (small nanopores) are presented. The Cu and Mn cations both adsorbed via an outer-sphere mechanism on zeolite Y based on the similarity between the adsorbed spectra and the aqueous spectra. Conversely, Mn and Cu adsorbed via an inner-sphere mechanism on mordenite based on spectrum asymmetry and peak broadening of the adsorbed spectra. However, Mn adsorbed via an outer-sphere mechanism on ZSM-5, whereas Cu adsorbed on ZSM-5 shows a high degree of surface interaction that indicates that it is adsorbed closer to the mineral surface. Evidence of dehydration and immobility was more readily evident in the spectrum of mordenite than in that of ZSM-5, indicating that Cu was not as close to the surface on ZSM-5 as it was when adsorbed on mordenite. Divalent Mn cations are strongly hydrated and are held strongly only in zeolites with small nanopore channels. Divalent Cu cations are also strongly hydrated, but can dehydrate more easily, presumably due to the Jahn-Teller effect, and are held strongly in zeolites with medium-sized nanopore channels or smaller.
A Molality-Based BET Equation for Modeling the Activity of Water Sorbed on Clay Minerals
Authors: Reynolds Jacob G. , Johnston Cliff T. , Agnew Stephen F.
Published: February 2013

The Brunauer-Emmett-Teller (BET) theory models the effective specific surface area and water content of solids as a function of the relative vapor pressure of water. A modified form of the BET equation has been used successfully to model water activity in concentrated electrolyte solutions as a function of electrolyte concentration. This modified form, referred to here as the Stokes-Robinson BET model, is based on the electrolyte molality rather than on the mass of solute sorbed. The present study evaluates the Stokes-Robinson form of the BET equation to model water-sorption data on two smectites with different layer charges. One smectite was saturated with Na+ and another with Na+, Ca2+, or Mg2+. These results are compared to the Stokes-Robinson BET results of aqueous electrolyte solutions. Given published data on cation exchange capacities and water-vapor sorption isotherms for various clays, the molality of the aqueous phase in contact with the clay surface is calculated and related to water activity. The Stokes-Robinson BET model was found to describe accurately the water activity as a function of cation molality below water activities of 0.5 for the smectites. Good relative agreement was obtained between the number of water binding sites predicted by the model and the experimental data reported in the literature for other smectites. Water molecules were found to have a significantly greater affinity for montmorillonite than electrolyte solutions with the same cation molality as the montmorillonite interlayer. This modified BET approach simplifies water-activity modeling in highly saline environments because the same equation can be used for both the liquid- and mineral-surface phases.
Laboratory-Simulated Diagenesis of Nontronite
Authors: Miller Matthew A. , Madden Andrew S. , Elwood Madden Megan , Elmore R. Douglas
Published: February 2013

Nontronite NAu-1 was exposed to moderate temperature and pressure conditions (250 and 300°C at 100 MPa pressure) in KCl brine to simulate burial diagenetic systems over accelerated time periods appropriate for laboratory experiments. Powder X-ray diffraction and transmission electron microscopy analysis of the coexisting mixed-layer and discrete 10 Å clay reaction products, and inductively coupled plasma-mass spectrometry analysis of the remaining fluids, indicated that the clay retained octahedral Fe and was identified as Fe-celadonite. The release of Fe from smectite during burial diagenesis has been hypothesized as a mechanism for magnetite authigenesis. High Al activity relative to Fe may be critical to the formation of an aluminous illite and any associated authigenic magnetite.
Mineralogy and Geochemistry of the Sedimentary Kaolin Deposits from Sinai, Egypt: Implications for Control by the Source Rocks
Authors: Baioumy Hassan M. , Gilg Albert , Taubald Heinrich
Published: February 2013

Mineralogical and geochemical variations among the Carboniferous and Cretaceous sedimentary kaolin deposits from Sinai provided an opportunity to examine the effect of the source area on compositions of the deposits. The Carboniferous kaolin deposits are mineralogically and geochemically heterogeneous. The Khaboba and Hasbar deposits consist of kaolinite, quartz, anatase, illite, chlorite, zircon, and leucoxene. The shale-normalized rare earth element (REE) patterns of the Khaboba deposit showed a slight LREE over HREE enrichment ((La/Yb)SN = 1.19–1.51) with a MREE depletion (Gd/Gd*SN = 0.51–0.75), while the Hasbar kaolin had a MREE enrichment. The Abu Natash kaolin deposit consisted of kaolinite, anatase, and a little quartz with larger TiO2, Cr, and V and smaller Zr and Nb contents compared to other Carboniferous deposits. The shale-normalized REE patterns of the Abu Natash deposit exhibited a positive Eu anomaly (Eu/Eu*SN = 1.28–1.40) and a MREE enrichment (Gd/Gd*SN = 1.41–2.05). The Cretaceous deposits were relatively homogeneous in terms of mineralogical composition and geochemistry and are composed of kaolinite, quartz, anatase, rutile, zircon, and leucoxene. The Cretaceous kaolin deposits showed mostly flat shale-normalized REE patterns with a variable LREE depletion.

The presence of illite and chlorite, the absence of rutile, large Zr and Nb contents, and the REE patterns suggested a component of weathered low-grade metasediments as a source for the Carboniferous deposits in the Khaboba and Hasbar areas, while the large Ti, Cr, and V, and small quartz contents indicated mafic source rocks for the Abu Natash deposit. The abundance of high-Cr rutile and the absence of illite and chlorite, and large Zr, Ti, Cr, and V contents suggested a mixture of medium- to high-grade metamafic and granitic rocks as source rocks for the Cretaceous kaolin deposits. The occurrence of alkaline rocks in the source of the deposits studied was identified by high-Nb contents and the presence of bastnaesite. The mineralogical and geochemical heterogeneity and lesser maturity of the Carboniferous deposits suggested local sources for each deposit and their deposition in basins close to the sources. The mineralogical and geochemical homogeneity and maturity of the Cretaceous deposits, on the other hand, indicated common sources for all deposits and their deposition in relatively remote basins.
Determination of the Predominant Minerals in Sedimentary Rocks by Chemometric Analysis of Infrared Spectra
Authors: Ritz Michal , Vaculíková Lenka , Plevová Eva , Matýsek Dalibor , Mališ Jiří
Published: February 2013

The objective of the present study was to determine the predominant minerals in sedimentary rocks using Fourier-transform infrared (FTIR) spectroscopy and chemometric analysis. The chemometric analysis was performed on three types of sedimentary rock samples (claystones, clay slates, and sandstones), each with different predominant mineral components. Chemometric models were created to determine the major minerals of the rock samples studied — chlorite, muscovite, albite, and quartz. The FTIR spectra were obtained in transmission mode from pressed pellets of KBr-sample mixtures or by diffuse reflectance from hand-packed mixtures of samples with KBr. Spectral regions measured were 4000-3000 and 1300–400 cm-1, which contained important spectral information for the creation of the chemometric models. Principal component analysis was used in the chemometric method, with calibration models being created by a partial least-squares regression method. The mean relative error, standard error of prediction, and relative standard deviation were calculated for the assessment of accuracy, precision, and reproducibility. The value of the mean relative error was 15–20% for most of the calibration models; the value of the standard error of prediction was up to 6 w/w % for most of the calibration models. The values of the standard relative deviation ranged from ~2 to 8% for calibration models based on diffuse reflectance spectra whereas calibration models based on transmission spectra had values of relative standard deviation of ~15-20%.

Measurement of Thyroglobulin by Liquid Chromatography–Tandem Mass Spectrometry in Serum and Plasma in the Presence of Antithyroglobulin Autoantibodies
Authors: Kushnir Mark M , Rockwood Alan L , Roberts William L , Abraham Dev , Hoofnagle Andrew N , Meikle A Wayne
Published: February 2013

BACKGROUND

Measurement of serum thyroglobulin (Tg) is used to monitor patients after treatment for differentiated thyroid carcinoma (TC). Difficulty in using Tg as a biomarker of the recurrence of TC in many patients stems from the presence of endogenous anti-Tg autoantibodies (Tg-AAbs), which can interfere with immunoassays (IAs) and cause false-negative results.

METHODS

We enriched Tg from serum samples using rabbit polyclonal anti-Tg antiserum and protein precipitation. Unrelated proteins were partially depleted in the process. Enriched proteins were then denatured, reduced, and digested with trypsin after the addition of a winged internal standard peptide. A Tg-specific tryptic peptide was purified by immunoaffinity extraction and analyzed by 2-dimensional LC-MS/MS. Instrument cycle time was 6.5 min per sample.

RESULTS

The lower limit of quantification was 0.5 ng/mL (0.76 fmol/mL dimer). Total imprecision of triplicate measurements in serum samples over 5 days was <10%. Comparison with a commercial IA using serum samples free of Tg-AAb (n = 73) showed Deming regression, IA = 1.00 * LC-MS/MS − 2.35, r = 0.982, standard error of the estimate (Sy|x) = 9.52. In a set of Tg-AAb–positive samples that tested negative for Tg using IA (n = 71), concentrations determined by LC-MS/MS were ≥0.5 ng/mL in 23% of samples (median 1.2, range 0.7–11 ng/mL).

CONCLUSIONS

The introduced method has acceptable performance characteristics for use in clinical diagnostic applications. The most substantial disagreement between methods was observed in Tg-AAb–positive samples with concentrations <2 ng/mL (determined with LC-MS/MS). The affinity-assisted enrichment strategy used for Tg in this method should be applicable to other biomarkers that have endogenous autoantibodies.
Automata: Serious craft genre or frivolous amusement
Authors: Grayson John
Published: February 2013

I am engaged in an ongoing investigation of traditional industrial metalworking processes and their application within a contemporary crafts context. I am engaged in using craft to play the role of industrial archaeologist. My investigations have resulted in two strands of work. First,
‘Vintage Tin’ is a range of printed tin automata inspired by Victorian 1940s, 1950s and 1960s tin toys. For this range I utilize a hybrid print and pressing process that I have developed through research into industrial tin toy and box manufacturing. The second body of work, ‘Faux
Georgian’, is a set of interactive enamel boxes inspired by the aesthetic, making process and historic context of Georgian enamel objects. Both sets of work are made in response to contemporary happenings and events. They are concerned with exploring and developing process relevant to
the craft arena, as well as documenting and celebrating dying and defunct manufacturing processes.
‘Making’ our way through: DIY and crafting communities in Toronto
Authors: Hagedorn Arden , Springgay Stephanie
Published: February 2013

Drawing on an interview-based research project on Do-It-Yourself and crafting culture in Toronto, this essay explores three themes of “why craft”?: the need for personal gratification and identity-building; the desire to build a community with shared values; and the need
to connect with a sense of humanity through labour in an increasingly technological and urban world. Though emerging craft communities may appear niche-like and closed off from mainstream forms of knowledge creation, discussion on these particularities provides us with examples of how crafting
may benefit learning processes not originally connected to crafters. Examining what it means to craft in Toronto, and in larger independent DIY contexts may also make recognizable new models of learning that are based on communities of practice not typically associated with standards-based
education.

‘The Song is You’: How music works in Sesame therapy for clients with dementia
Authors: Butler Catherine
Published: February 2013

It is increasingly being recognized, both empirically by carers and through rapidly advancing research in music psychology and neuroscience, that music can assist the well-being of people living with dementia. In this article I show my work as a Sesame practitioner, demonstrating my
therapeutic use of music and giving examples of how it speaks to the needs of this client group, including those of self-expression and relationship; and I show how music fits into the Sesame context of Drama and Movement, which includes Laban Fundamentals. I give an introduction to Sesame
beginning with a vignette from one-to one work that illustrates our practice. I describe a group therapy session from a series, explaining the Sesame session structure and the use of music in relation to this. I detail effects I noted as participant/observer, and my subsequent reflections;
I refer throughout to pertinent literature including some recent neuroscientific research.
Television regulation after digital switchover: A personal view
Authors: Suter Tim
Published: February 2013

Digital switchover and digital convergence challenge regulators to re-examine the justifications for regulating television content. These can be grouped under three headings: access, contribution and protection. Each of these areas is challenged to respond to three key pressures: the
decline of the linear schedule; the emergence of connected TV; and the emergence of new players in the business value chain. Regulators will need to refine existing approaches, develop new tools and empower audiences to take more control for themselves. Although digital television will both
encompass new services and sit alongside other audio-visual services with different roots and different regulation, its specialness will continue to justify a regulatory regime that underpins its contribution and potential impact.
Pluralism in crisis: Transformations of the spanish DTT market in the context of the recession
Authors: Aalonso Isabel Fernández , Díaz-González María-Jesús
Published: February 2013

This article discusses the most significant aspects of DTT’s evolution in Spain since the analogue switch-off in April 2010. It underscores the severe cutbacks affecting public service television broadcasters and their impact, as well as a return to government control over the
Spanish Broadcasting Corporation (RTVE) in particular. It also emphasizes the major tendency towards concentration in the national private DTT market and the inviability of most regional and local broadcasters. All of these issues are analysed from the perspective of their worrying impact
on pluralism.
Effects of extended practice with computerized eye guides for sight-reading in collegiate-level class piano
Authors: Hagen Sara L. , Cremaschi Alejandro , Himonides Cynthia Stephens
Published: February 2013

Collegiate class piano courses demand sight-reading competencies and many pedagogical approaches exist, but there is relatively little information regarding the use of computerized settings for practice of this skill in environments that seek to guide the eye in learning to sight-read
piano music. This study followed a series of examinations of computerized eye guides including the sweep, the highlighted measure, and the note-to-note guides in learning to sight-read. Four groups of randomly placed college-level class piano students (N=69) practiced sight-reading for six
weeks, in fifteen-minute sessions, in one of four environments: Finale Performance Assessment (sweep) (n=20), Home Concert Xtreme (highlighted measure) (n=18), Flash animation (note-to-note highlight) (n=16), and a control group using paper and a metronome (n=15). All environments contained
a metronomic click, but no additional sound reinforcement. Results indicated that all groups significantly improved, but no significant differences were found among the groups. Pedagogical implications are discussed along with suggestions for future research.
Locating ‘The Road to Lisdoonvarna’ via autoethnography: Pathways, barriers and detours in self-directed online music learning
Authors: Kruse Nathan B.
Published: February 2013

This autoethnography documents the author’s experiences in learning to play mandolin purely through online resources over the course of nine months. Specifically, this self-study explored the rewards and challenges he associated with online mandolin instruction and the teaching
styles he perceived as the most effective. Data sources included notes from online folk music instructional videos, personal journal entries, weekly practice logs and recorded practice sessions, all of which traced the learning process spanning the nine-month time period. Findings indicated
that enculturation was an important part of the journey, as was the abundance and diversity of online tutorials. Role conflict and frustration emerged as distinct challenges, however, along with a sense of isolation as the study progressed. Additionally, instructors who transmitted an engaging
disposition produced the most emotive and educative video lessons. Implications include practical applications of online learning as well as the possibilities of conducting autoethnography in music education research.

Jihad through ‘music’: The Taliban and Hizbullah
Authors: Alagha Joseph
Published: February 2013

This article discusses the cultural politics of the Taliban and Hizbullah. While Hizbullah embraces ‘resistance art’ and encourages purposeful music and artistic expressions as pious entertainment, the Taliban censor music and restrict artistic activities, considering them
innovations (bida‘) that distract from the practice of ‘authentic Islam’ and ‘true worship’. To discuss the interplay between the ‘power of music’ and ‘music in power’, this article uses samples of anashid (songs, hymns and anthems) of
the Taliban and Hizbullah, both of which practice jihad through music. Most notably, both employ the same Qur’anic concept of ‘action of excellence under God’s guidance’, either to legitimize and justify certain artistic expressions and practices (Hizbullah) or to ban
and prohibit them all together (the Taliban). Hizbullah’s contextual argument leads to a music theory, whilst the Taliban’s prohibition in the absolute curtails cultural politics all together.
Music on Dutch Moroccan websites
Authors: Merolla Daniela
Published: February 2013

Music is present online and offline alike, only amplified in volume and diffusion by the increase in audio and visual technology. However, music is controversial as well, when we consider current and long-term debates over acceptance and rejection of music in Islam. Looking at music
as both social practice and artistic product, this article investigates its presence on websites created by Dutch Moroccans in the Netherlands and explores the way in which Internet-mediated music contributes to characterizing such sites. Five websites are investigated: El Tawheed, which is
presented by other sites as the site of a ‘Moroccan mosque’, Ontdekt Islam/Discover Islam, Maroc.nl, which is a popular website, and two Berber websites, Amazigh.nl and Tawiza.nl. The analysis ties in with results and insights of a rich amount of works that have addressed websites
variously indicated as ‘Muslim’, ‘allochthonous’, ‘ethnic’, ‘minority’ and ‘migrant’.1 Studies by J. W. Anderson, A. Appadurai and D. Miller and D. Slater have been source of inspiration. Finally, this article discusses the adequacy
of the religion/secularism opposition in understanding ideas and prac¬tices of music as expressed by Dutch Moroccan websites.
‘Mutants of the 67th parallel North’: Punk performance and the transformation of everyday life
Authors: Pilkington Hilary
Published: February 2013

On a hand-made poster in the ‘HQ’ of the Biker Club in Vorkuta, the three members of the local punk band Mazut loom out of the darkness, their faces comically distorted and framed either side by the words ‘Fucking noise’ and ‘Mutant-morons’. This
article traces tropes of ‘mutation’, ‘mutant’ and ‘moron’ within the music, performance and self-identifications of punk scene members drawing on interviews, field notes, audio and visual recordings gathered in autumn 2009 in the city of Vorkuta in Russia’s
far North. It explores the ‘mutant’ hero as it appears in facial and bodily gestures, song lyrics and everyday talk on the punk scene. It considers the meanings attached to the practice of ‘mutation’ among scene members as well as the unarticulated role it plays in
signalling a boundary crossing between ‘everyday life’, marked by heavy physical and emotional demands of routines of paid employment and family lives, and ‘subcultural life’, as a practice of the enactment of (a consciously temporary) freedom from them.
Voice of the people? Objectives versus outcomes for community radio in Ireland
Authors: O’Brien Anne , Gaynor Niamh
Published: February 2013

Research has neglected to address the question of whether practitioners and the community groups served by community radio see it as a conduit of community empowerment and social change. This article explores this question through in-depth analysis of four community radio stations in
Ireland. The central finding is that, while community stations subscribe to most of the ideals of community radio, practitioners do not generally see the stations as sites of social and political empowerment. Moreover, this outcome is not recognized as a benefit by the communities served by
the stations. This is the case because of the policy framework, cultural traditions and training programmes central to community radio in Ireland, the weakness of linkages between stations and community groups and the failure of the latter to understand the unique remit of community radio.
Sondheim’s use of the ‘Herrmann chord’ in Sweeney Todd
Authors: Mcgill Craig M.
Published: February 2013

When Stephen Sondheim approached the score for his 1979 musical thriller Sweeney Todd, the Demon Barber of Fleet Street, he felt compelled to write it as if it were the score for a horror film. Particularly inspired by the music of film composer Bernard Herrmann, Sondheim crafted his
score around a quintessential harmony that Hermann used in most of his film scores: a minor/major seventh chord, or 4–19 (0148). Since this unstable sonority has qualities of both major and minor, its ambiguous particulars allow for many harmonic possibilities. Although the ‘Herrmann
chord’ is conceived as a vertical harmony in a specific inversion (seventh in the bass), both Sondheim and Herrmann use this sonority in other fascinating ways. For this reason, my analysis will extend the ‘Herrmann chord’ to consider its intervallic constituents employing
Pitch-Class Set Theory, which will allow for a broader, more expansive contextual study of Sweeney Todd.
Arms and the girls: Tthe powerful weapon that is women writing women for the musical stage
Authors: Pressley Kristin Stultz
Published: February 2013

Dorothy Fields was a Broadway lyricist and librettist, whose career spanned from the mid-1920s until her death in the mid-1970s. For much of the Golden Age of the American musical, Fields was one of the only women writing for the Broadway theatre. As such, her voice is distinct in many
ways. The project of this article is to determine that voice and, in so doing, to establish her unique contribution to the canon of musical theatre. Illustrating Fields’ enigmatic voice is the primary intent of this article. A secondary purpose, to be addressed later, is examining the
extent to which women today are following in her footsteps.
Metapher und Wissenstransfers im informationsbezogenen Diskurs / Metaphor and knowledge transfer in informationrelated discourse / Métaphore pour le transfert des connaissances dans le discours relatif à l’information
Authors: Engerer Volkmar
Published: February 2013

Der vorliegende Beitrag1 ist ein Versuch, Eigenschaften von Schöns generativer Metapher auf das „statische“ Resultat als Fachterminologie, entstanden durch Übertragung eines wissenschaftlichen Bereiches in einen anderen, anzuwenden. Metapher gilt in diesem Bereich als wissenstransferierendes Verfahren der Übertragung von Konzepten einer Disziplin auf eine andere. Weiterhin wird Metapher als Teil des sprachlichen Jargons in der informationswissenschaftlichen und bibliothekarischen Praxis thematisiert. Ein kurzer Durchgang des dänischen bibliotheksmetaphorischen Wortschatzes zeigt u. a., dass in dieser Domäne ein „ontologisches Erfahrungsgefälle“ von abstrakt-konkret wirksam ist, da viele bibliothekstechnische, computer-interaktionsbezogene und informationswissenschaftliche Begriffe mit Hilfe konkreterer Konzepte aus besser verstandenen Domänen, z. B. dem Bereich der Nahrungsaufnahme, erklärt werden. Allerdings scheint auch hier der Anteil „entmetaphorisierter“, ehemals metaphorischer Ausdrücke hoch zu sein, wie es bei „abgeschliffenen“ Ausdrücken auch in der Gemeinsprache der Fall ist. Die Analyse wird abgerundet mit einem Ausblick auf ein Forschungsgebiet, das in dezidierter Weise von der konzeptuellen Ergiebigkeit des Metaphernbegriffs in der Untersuchung der terminologischen Wissenschaftsbeziehungen Gebrauch macht
Oncologic safety of skin-sparing mastectomy followed by immediate breast reconstruction: rate and localization of recurrences, and impact of reconstruction techniques
Authors: Romics jr. László , Stallard Sheila , Weiler-Mithoff Eva
Published: February 2013

Introduction: Oncological safety of skin-sparing mastectomy followed by immediate breast reconstruction is widely debated. Current evidence is relatively poor since it is based mostly on short-term follow-up data of highly selected patient populations. Aim: Recurrence rates of a large cohort of non-selected patients, i. e. “all-comers” were analyzed during a 10-year follow up. Methods: Patient records and follow-up data of 253 consecutive cases treated with of skin-sparing mastectomy and immediate breast reconstruction between 1995 and 2000 were studied. During this time period “all-comers” policy was applied, which meant that all patients treated with mastectomy were offered immediate breast reconstruction regardless of tumour stage. Results: “All-comers” approach resulted in a large proportion of patients with more advanced disease. During the 112 months mean follow-up 8.2% locoregional, 2.9% local, 10.6% distal and 18.8% overall recurrence rates were detected. Breast cancer specific survival rate was 90.9%. Autologous breast reconstruction was applied more frequently in patients with higher tumour stage; therefore recurrence rate was higher compared to patients undergoing implant-based reconstruction. Conclusion: Based on these long-term follow-up data skin-sparing mastectomy combined with immediate breast reconstruction is an oncologically safe treatment option. Therefore, application of “all-comers” policy for breast cancer patients treated with skin-sparing mastectomy followed by immediate breast reconstruction is feasible. Orv. Hetil., 2013, 154, 163–171.
Peripheral venous access with ultrasound guidance
Authors: Reusz Géza , Csomós Ákos
Published: February 2013

Peripheral venous cannulation is a routine procedure. The method is usually easy, however, occasionally it may prove to be difficult or even impossible to perform. Ultrasound can visualize deep veins that are undetectable by palpation and it makes possible to cannulate these veins under direct visual control. Authors routinely use ultrasound for difficult peripheral venous access. In this report they present 3 cases and discuss the practical aspects of ultrasound-guided peripheral venous access. Venous circulation of the arm is briefly reviewed, and ultrasound guidance techniques are discussed with regards to sterility aspects. Furthermore, authors describe a new technique wich they use efficiently for cannulating patients with poor peripheral venous access. Orv. Hetil., 2013, 154, 187–190.
Anthropometric data, fetal and neonatal complications in infants of diabetic mothers. Results of a 10-year retrospective study

Published: February 2013

Introduction: Disturbances in carbohydrate metabolism during pregnancy may result in harmful fetal and neonatal consequences. Objectives: To assess the fetal and neonatal complications of pregnancy in mothers with gestational and pregestational diabetes during a 10-year period in a county hospital in Hungary. Methods: Retrospective analysis of infants of diabetic mothers admitted to the neonatal unit between 2001 and 2010. Results: 32% of the infants were transferred to the neonatal unit. Neonatal macrosomia (birth weight >90 centile) was observed in one quarter of the infants. 39% of the infants developed hypoglycemia (blood glucose <2.6 mmol/l), in the majority of the cases within the first 8 hours. Hypoglycaemia was symptomatic in 55% of the infants. Hypocalcemia was observed in 17%, hyperviscosity in 23%, hyperbilirubinaemia in 32%, respiratory distress syndrome and/or transient tachypnoe in 22% and cardiac complications in 13% of the infants. 10% of the inafnts were affected with birth injuries. Congenital anomalies were seen in 17% of the cases, and severe malformations were present in 4% of the infants. Conclusions: Despite modern diabetes management, there is still a higher incidence of fetal macrosomia, adverse neonatal outcomes and a higher rate of severe congenital malformations in neonates of diabetic mothers.

Determinação do sexo do pinto pela forma do ovo
Authors: Torres A. Di Paravicini
Published: February 2013

Este trabalho foi feito afim de determinar uma hipotética correlação existente entre a forma do ôvo e o sexo do pinto. Dois métodos foram utilizados. No primeiro considerou-se apenas a "ponta" do ôvo, dividindo-se um lote de 1100 ovos em dois grupos, um considerado ponteagudo e outro arredondado. Os resultados totais mostraram a nenhuma influência da forma da ponta na determinação do sexo, isto é, a falta de correlação era completa. No segundo método, determinou-se a média da relação entre a largura e o comprimento do ôvo, e adotou-se essa medida como linha divisória de dois grupos : um de ovos grossos com 223 ovos e outro de ovos finos, com 183 ovos. A relação sexual foi respectivamente de 38.60 e 37.07 o que mostra a falta de correlação. Os dez ovos mais compridos e os dez mais redondos, incubados separadamente, confirmaram os resultados anteriores. A determinação do sexo dos pintos foi feita pelo método de JAAP, aperfeiçoado nesta Seção. O Autor conclui, que na população estudada, da raça Rhode I. Red, não existe absolutamente a menor correlação entre a forma do ôvo e o sexo do pinto que êle possa determinar. Acredita que essas conclusões possam se aplicar a todas as variedades industriais, mas acha possível, que em raças muito antigas não provenientes de cruzamentos, talvez nalguma raça de briga, tal correlação possa existir.

RACIONAL: A gastrorrafia isolada ou associada ao uso de adesivos biológicos constituiu ao longo da história da cirurgia a forma usual de promover a cicatrização nas lesões gástricas e o uso de fitoterápicos tem sido cada vez mais empregado. OBJETIVO: Avaliar a cicatrização de ferida provocada no estômago de ratos com uso do extrato hidroalcoólico de Schinus terebinthifolius Raddi. MÉTODOS: Foram utilizados 60 ratos, adultos, machos, distribuídos em dois grupos: grupo aroeira e grupo controle, os quais foram subdivididos em três subgrupos de cinco animais conforme o momento das mortes dos animais (7, 14 e 21 dias). Todos os animais foram submetidos ao mesmo procedimento cirúrgico (lesão e rafia do estômago) diferindo apenas que os animais do grupo aroeira receberam dose diária de 100 mg/kg do extrato hidroalcoólico via gavagem enquanto o grupo controle recebeu solução salina isotônica. Os parâmetros avaliados foram: alterações macroscópicas e microscópicas, teste de resistência à insuflação de ar atmosférico e teste pela força de tração. RESULTADOS: Todos os animais demonstraram boa cicatrização da parede abdominal e das gastrorrafias, sem infecção e deiscência. Ambos os grupos apresentaram aderências à superfície das gastrorrafias com órgãos vizinhos. O teste de resistência por insuflação de ar atmosférico e força de tração mostraram maiores médias de pressão no 7º dia e de força de ruptura nos períodos estudados para o grupo aroeira. A intensidade da inflamação crônica revelou diferença estatisticamente significante nas variáveis proliferação fobrobrástica e colagenização. CONCLUSÃO: O uso do extrato hidroalcoólico de Schinus terebinthifolius Raddi acelerou a cicatrização do estômago de ratos.

RACIONAL: A doença do refluxo gastroesofágico é afecção crônica de elevada prevalência nos países ocidentais e com efeitos negativos sobre a qualidade de vida. O tratamento cirúrgico é indicado para pacientes que necessitam usar medicamentos ininterruptamente, intolerantes ao controle clínico prolongado e nas formas complicadas da doença. OBJETIVO: Avaliar a qualidade de vida de indivíduos submetidos à correção cirúrgica por videolaparoscopia, para tratamento da doença do refluxo gastroesofágico. MÉTODOS: Foram avaliados 43 pacientes com idade média de 51,4 anos, de ambos os gêneros nos últimos dez anos, utilizando-se o questionário Escala de Qualidade de Vida Relacionada à Saúde para doença do refluxo gastroesofágico (1996), traduzido e validado para a língua portuguesa. Os dados foram analisados pelo programa estatístico Epi Info versão 3.5.1, com auxilio do teste de Duncan e do coeficiente de correlação de Pearson, fixando-se o valor de 5% para a hipótese de nulidade (p<0,05). RESULTADOS: Mais de 50% dos participantes demonstraram boa qualidade de vida (escores<5 do questionário); 95,3% indicaram satisfação com seu estado de saúde. Observou-se correlação positiva significativa entre a maioria das variáveis referentes à pirose e ao tempo após a operação (p<0,05). CONCLUSÃO: Os pacientes apresentaram boa qualidade de vida e elevado grau de satisfação com sua condição pós-operatória.

RACIONAL: A literatura oriental é notável por apresentar taxas de sobrevida para o tratamento cirúrgico do adenocarcinoma gástrico superiores àquelas apresentadas nos países ocidentais. OBJETIVO: Analisar o resultado a longo prazo após a gastrectomia D2 por câncer gástrico. MÉTODOS: Duzentos e setenta e quatro pacientes foram submetidos à gastrectomia com dissecção linfonodal D2 como tratamento exclusivo. Os critérios de inclusão foram: 1) remoção dos linfonodos de acordo com dissecção linfática padronizada Japonesa, 2) operação potencialmente curativa descrita no prontuário como dissecção D2 ou mais linfonodos; 3) invasão tumoral da parede gástrica restrita ao órgão (T1-T3); 4) ausência de metástases à distância (N0-N2/M0); 5) mínimo de cinco anos de acompanhamento. Dados clinicopatológicos incluíam sexo, idade, localização do tumor, classificação de Borrmann do tumor macroscópico, o tipo de gastrectomia, as taxas de mortalidade, tipo histológico, classificação e estadiamento TNM de acordo com a UICC TNM 1997. RESULTADOS: Gastrectomia total foi realizada em 77 casos (28,1%) e subtotal em 197 (71,9%). O tumor foi localizado no terço superior em 28 casos (10,2%), no terço médio em 53 (19,3%), e no terço inferior em 182 (66,5%). Borrmann foi atribuído cinco casos (1,8%) como BI, 34 (12,4%) BII, 230 (84,0%) BIII e 16 (5,9%) BIV. Os tumores foram histologicamente classificados como Laurén tipo intestinal em 119 casos (43,4%) e como o tipo difuso em 155 (56,6%). De acordo com a UICC TNM foram câncer gástrico precoce (T1) foi diagnosticada em 68 casos (24,8%); 51 (18,6%) T2 e 155 (56,6%) T3. Nenhum envolvimento linfonodal (N0) foi observado em 129 casos (47,1%), enquanto 100 (36,5%) eram N1 (1-6 linfonodos) e 45 (16,4%) N2 (7-15 gânglios linfáticos). O número médio de linfonodos dissecados foi de 35. A sobrevida em cinco anos para os estádios de I a III B foi de 70,4%. CONCLUSÃO: Cirurgiões digestivos devem ser estimulados a realizarem gastrectomias D2 para não deixar de lado o único tratamento para adenocarcinoma gástrico que provou ser eficiente os dias atuais. Deve ser enfatizado que a padronização da dissecção linfática de acordo com a localização do tumor é mais importante do que apenas o número de gânglios removidos

INTRODUÇÃO: Com o advento dos anestésicos locais de longa duração, a anestesia locorregional ganhou grande impulso sendo cada vez mais utilizada. Novas técnicas de bloqueios foram descritas e a técnica é frequentemente associada à anestesia geral com o objetivo de proporcionar analgesia pós-operatória. A contra-partida é a necessidade da utilização de grandes doses com risco de acidentes por injeção intravascular inadvertida; trata-se de complicação grave sem tratamento específico até há alguns anos. Em 1998 foi proposta a utilização de emulsões lipídicas em animais e a partir de 2006 vários trabalhos demonstraram o interesse dessas soluções nos casos de intoxicações por anestésicos locais com diminuição da morbi-mortalidade. O objetivo desta revisão foi fazer um levantamento da metodologia, revisando os mecanismos, interesses, limites e as condutas preconizadas atualmente. MÉTODO: Foram revistas algumas referências históricas sobre anestésicos locais, artigos publicados nos últimos 30 anos em revistas indexadas no Medline e em dois livros-texto. Foram selecionados os artigos que tratavam da intoxicação por anestésicos locais, da terapia com emulsões lipídicas, os de revisão sobre o assunto e as condutas adotadas em diversos serviços e países, sendo realizada uma síntese. CONCLUSÕES: A eficiência e interesse da terapia com emulsões lipídicas nas intoxicações por anestésicos locais não é mais a demonstrar; várias sociedades da especialidade já publicaram suas diretrizes e aconselham que se disponha desses produtos nos locais onde se pratica a anestesia locorregional.

INTRODUÇÃO: O controle da obesidade mórbida pode ser realizado através da cirurgia bariátrica que leva à restrição e/ou à má-absorção de alimentos. O objetivo dessa revisão foi identificar consequências desse procedimento e suas repercussões na saúde bucal. MÉTODO: Foi realizada busca na Biblioteca Virtual em Saúde, sendo incluídos artigos com relação direta ou indireta entre cirurgia bariátrica e saúde bucal e publicados nos últimos dez anos. RESULTADOS: Verificaram-se algumas complicações decorrentes dessa operação, como regurgitação crônica e deficiências nutricionais, que podem trazer repercussões na cavidade bucal como erosão dentária, perda óssea e cárie dentária. Por outro lado, existem consequências positivas como controle da diabetes, da apnéia e melhora da auto-estima, que tornam os pacientes menos susceptíveis à complicações na cavidade oral, como xerostomia e doença periodontal. CONCLUSÃO: A manutenção da saúde bucal adequada em pacientes submetidos à cirurgia bariátrica contribui para o sucesso após a operação, resguardando os benefícios e minimizando os efeitos colaterais.

Published: February 2013

RACIONAL: A cirurgia minimamente invasiva ganhou rapidamente papel fundamental no tratamento da doença do refluxo gastroesofágico. Entretanto, o melhor método para as grandes hérnias paraesofágicas (tipos III e IV) ainda está em discussão. O uso de próteses para reforço da hiatoplastia tem sido proposto por diversos autores, no intuito de diminuir as altas taxas de recidivas encontradas nesses pacientes. Riscos de estenose e erosão da prótese são as complicações mais preocupantes quando se pensa em aplicar uma prótese no hiato esofágico. OBJETIVO: Demonstrar a técnica cirúrgica e resultados do uso de um modelo de tela idealizado no serviço dos autores para reforçar a hiatoplastia em grandes hérnias de hiato. MÉTODOS: Uma prótese de polipropileno foi aplicada para reforço da hiatoplastia em pacientes com grandes hérnias de hiato (Tipos II a IV de Hill). A prótese era cortada em forma de U, com sutura de cateter de silicone na borda côncava que ficaria em contato com o esôfago. Após sua fixação sobre a hiatoplastia, toda prótese era recoberta por gordura do omento maior, impedindo contato com o fundo gástrico ou fundoplicatura. RESULTADOS: De 1999 a 2012, esta técnica foi utilizada em 70 pacientes. Eram 52 do sexo feminino e 18 do sexo masculino, com idades variando de 32 a 83 anos (média de 63 anos). Em 48 (68,6%) pacientes, tratava-se de hérnias primárias e em 22 (31,4%) era recidivada após operação antirrefluxo. O único óbito ocorreu por sepse (1,4%) no 22o dia pós-operatório em caso com laceração da sutura da fundoplicatura causando fístula gastropleural. Não houve relação direta com o uso da prótese. Seguimento de seis meses ou mais foi obtido em 60 pacientes (85,7%), variando de seis a 146 meses (média de 49 meses). Todos os pacientes foram submetidos à entrevista clínica e pelo menos uma endoscopia e/ou radiografia contrastada no período de acompanhamento. Durante o seguimento, não foram observadas complicações (estenose ou erosão) relacionadas com a prótese. CONCLUSÃO: O uso do modelo de prótese de polipropileno descrito é seguro, desde que observados os aspectos técnicos de sua implantação.
