Using Common Features to Investigate Common Growth Cycles for BRICS Countries
Authors: Delalibera Bruno Ricardo , Issler João Victor , Branco Roberto Castello
Published: December 2018

This paper examines the short and long-term co-movement of large  emerging market economies -- the BRICS countries -- by applying the  econometric techniques and the tests proposed in the common-feature literature. Despite their dissimilarities, given the rising trade linkages among the BRICS over the last 20 years one should expect their cycles to be  synchronized. Our empirical findings fully support this hypothesis. The evidence holds also for the co-movement between the BRICS and developed  economies, the US and the Eurozone, which may reflect the effects of  globalization.
A. J. Greimas, um projeto teórico em construção
Authors: Hénault Anne
Published: December 2018

Depois de recuperar as principais etapas pelas quais Greimas atravessou a linguística para fundar, concretamente, a semiótica geral, mostramos como o conceito de imanência define a identidade da semiótica que Greimas convidava a construir e a praticar. O princípio de imanência é o instrumento conceitual que permite atualizar, descrever e hierarquizar os jogos relacionais abstratos que constituem a gramática profunda das línguas e da linguagem. O novo saber que resulta da emergência da semiótica está inteiramente ligado a esse tipo de funcionamento mental cujo saber matemático constitui outro exemplo.
Percurso da semiótica por meio das obras de Greimas
Authors: Cortina Arnaldo
Published: December 2018

Como forma de homenagear um autor que teve e ainda tem grande importância para os estudos do discurso e da significação, o caminho escolhido foi seguir os registros de seu pensamento e de suas propostas ao longo das diferentes obras que publicou em vida. Sem a intenção de fazer uma apresentação exaustiva e aprofundada de todos os textos de Greimas, busca-se guiar o leitor no trajeto que a semiótica do discurso traçou ao longo dos seus anos de vida e nele despertar o interesse por uma proposta teórico-metodológica de tal envergadura e rigor científico.
Transposição e narratividade nos desenvolvimentos da semiótica atual
Authors: Leite Ricardo Lopes
Published: December 2018

Durante muito tempo o conceito de narratividade esteve no pináculo da teoria semiótica erigida por Algirdas Julien Greimas. No entanto, com a incorporação de novas problemáticas e, principalmente, sob a alegação de que a esquematização narrativa não daria conta de uma descrição exaustiva e mais adequada às singularidades dos conjuntos significantes não verbais, das práticas e das interações mais próximas do vivido, o sistema da narratividade foi paulatinamente deixando de ser uma preocupação teórica para os semioticistas. Com o propósito de prestar uma homenagem ao mestre lituano, este artigo se volta para a presença da narratividade nos desenvolvimentos da semiótica atual. Os objetivos são destacar a centralidade desse conceito dentro do modelo teórico de Greimas, examinar os desdobramentos da passagem de uma narratividade stricto sensu para uma narratividade lato sensu e, sobretudo, ressaltar seu alcance teórico, para além de sua função como ferramenta de análise circunscrita ao percurso gerativo do sentido ou como conceito emblemático da semiótica dita clássica. Assume-se, ao final, a narratividade como metaesquema, como um dispositivo de transposição do sentido, que pode ser mobilizado em diferentes níveis, dependendo da visada teórica ou analítica do semioticista, nos vários modelos da semiótica herdeira de Greimas.
Greimas e a semiótica do mundo natural
Authors: Klinkenberg Jean-Marie
Published: December 2018

Entre as disciplinas com que A. J. Greimas teve contato em sua formação aparece a fenomenologia, corrente filosófica que apresentou em termos renovados a delicada questão da relação entre a linguagem e o mundo. Como se sabe, a exigência epistemológica assumida por Greimas acabou por afastá-lo do fenômeno da referência, por ele considerado indecidível, levando-o a abraçar, sobretudo, a vertente construtivista da fenomenologia, a ideia de que o “fenômeno” requer o logos para mostrar-se. Por outro lado, ele não deixa de afirmar incisivamente em Semântica estrutural que “as significações do mundo humano situam-se no nível da percepção”. O problema da relação entre o sentido e um sensível não unicamente textual permanece, portanto, à espera de resposta. Foi tal problema que determinou o projeto greimasiano de uma “semiótica do mundo natural”, que não chegaria a ter todos os desenvolvimentos prometidos. O objetivo deste artigo é submeter esse conceito a uma apreciação crítica, mediante a sua colocação em contexto. Gostaríamos também de expor suas potencialidades – reveladas mais claramente neste século XXI, quando os avanços de novos conhecimentos permitem solucionar questões que não podiam ser abordadas há 50 anos – e os desafios trazidos por elas para a semiótica geral.
Práticas e formas de vida: a semiótica de Greimas posta à prova pela antropologia contemporânea
Authors: Fontanille Jacques
Published: December 2018

A leitura atenta de algumas das obras de Greimas, com destaque especial para o estudo de narrativas míticas nos dois volumes de Sobre o sentido (1975 [1970]; 2014 [1983]), aponta para a intuição antropológica de sua proposta e o alcance dos esquemas narrativos pertinentes para o que poderia ser uma abordagem semioantropológica. Como forma sintagmática do “sentido da vida”, o esquema narrativo canônico abre caminho ao exame dos regimes semióticos, à descrição das formas de vida e das práticas semióticas; logo, à análise do nível propriamente semiótico das produções culturais. Propõe-se, assim, com a ajuda da antropologia contemporânea, esboçar uma articulação entre os tipos de esquemas práticos (produtores de objetos culturais e simbólicos) e os modos de existência (coletivos), uma teoria e uma tipologia das práticas que possa diminuir a distância entre as semióticas da cultura e as semióticas textuais, devolvendo à teoria a sua dimensão antropológica, tal como Greimas havia começado a delineá-la.
Análise da análise: quadrado semiótico e gráfico tensivo
Authors: Saraiva José Américo Bezerra
Published: December 2018

Neste artigo pretendemos mostrar algumas das razões que sustentam a tomada de posição de Greimas frente à Filosofia, isto é, sua recusa a entrar na discussão sem fim acerca da origem do sentido. Não lhe interessava explicar, por exemplo, o sentido último das estruturas sintáticas que criava, se inerentes ao objeto ou incrustradas no aparelho cognitivo do sujeito, mas, partindo de pressupostos epistemológicos “pouco numerosos e tão gerais quanto possíveis”, proceder à formulação de estratégias de estruturação mínima do sentido via significação. Em seguida, buscamos demonstrar que o quadrado semiótico assume papel relevante como estratégia de manipulação do sentido via significação e que o gráfico tensivo constitui-se esquematicamente um seu prolongamento, voltado para a questão exclusiva do termo complexo.
A noção de texto e os níveis de pertinência da análise semiótica
Authors: Schwartzmann Matheus Nogueira
Published: December 2018

Neste artigo, busca-se refletir sobre a noção de texto em semiótica francesa, sobre a sua força metodológica e o seu modo de articulação com os desenvolvimentos mais recentes da teoria, sobretudo a perspectiva das práticas e dos níveis de pertinência da análise semiótica, conforme propostos por Jacques Fontanille. Apresenta-se aqui pelo menos duas interpretações da noção de texto, tendo como ponto de partida a famosa frase greimasiana (“Fora do texto não há salvação!”): texto será tomado ora (1) como unidade, como enunciado, em uma abordagem mais francamente imanente; ora (2) como semiótica-objeto complexa, como conjuntura ou nível de pertinência. Segundo essas duas leituras, busca-se ainda, para concluir, esboçar qual seria, atualmente, o alcance da análise semiótica.
Contribuições da semiótica greimasiana para a estratégia empresarial
Authors: Lopes Paulo Eduardo
Published: December 2018

O artigo relata experiências reais de emprego da semiótica greimasiana para a gestão estratégica numa empresa do setor financeiro, buscando mostrar a produtividade da proposta teórico-metodológica de Greimas nesse domínio. Diferentemente do que ocorre com a maioria das iniciativas anteriores – que privilegiam áreas ligadas ao marketing, como o branding e a propaganda –, este trabalho focaliza contribuições teóricas para a redefinição de conceitos e o desenvolvimento de novos métodos para práticas administrativas, como o modelo de relacionamento com clientes, a análise do macroambiente e o processo de planejamento estratégico.
Um olhar semiótico sobre a atualidade: a aspectualização a partir de Greimas
Authors: Gomes Regina Souza
Published: December 2018

Este artigo tem como objetivo, primeiramente, apresentar como a aspectualização vem sendo abordada na semiótica de linha francesa, ora tomando essa categoria como um procedimento do nível discursivo, incidindo sobre o tempo, a pessoa e o espaço, ora como uma nova contribuição metodológica, acolhendo o acento e a graduação, os afetos e a percepção, como propõe a semiótica tensiva. Para demonstrar a operacionalidade desse recurso, analisarei, da perspectiva da aspectualização, como se constituem os discursos considerados progressistas nos comentários de matérias polêmicas de veículos de imprensa no Facebook. Finalmente, ao mostrar a atualidade e a importância dessa categoria para a compreensão mais refinada da construção do sentido dos textos, faço uma homenagem a Greimas, em seu centenário de nascimento no ano de 2017, a partir de proposições teóricas fundadoras do autor.
Mediação semiótica para as novas formas de fazer-ver
Authors: Limoli Loredana , Mendonça Ana Paula
Published: December 2018

Em meio as grandes mudanças nas formas de dizer, de ser, e principalmente de fazer-ver, do mundo contemporâneo, a semiótica de Greimas surge como uma das correntes mais equipadas para a abordagem metodológica e analítica das múltiplas transformações discursivas, tão velozes quanto efêmeras. Com o objetivo de validar o instrumental da teoria na análise de textos pouco convencionais dentro da esfera de seus próprios gêneros, apresenta-se neste artigo uma leitura de objetos provenientes de três modalidades artísticas, de predominância visual ou verbovisual: a minissérie televisiva Justiça, a graphic novel Aqui e alguns exemplares de infográficos artísticos.
Dos estudos de usuários à noção de práticas informacionais
Authors: Nunes Jefferson Veras , Carneiro Bárbara Luisa Ferreira
Published: December 2018

Aborda a noção de práticas informacionais levando em conta o caráter interdisciplinar da Ciência da Informação, tomando como base os desdobramentos teóricos dos estudos de usuários. Como metodologia, adota a pesquisaexploratória, recorrendo também àpesquisa bibliográfica e documental, com foco na noção de práticas informacionais e na Teoria da Prática bourdieusiana. A partir da análise da literatura, destaca que a noção de práticas informacionais está estreitamente vinculada ao paradigma social da Ciência da Informação por incorporar questões mais amplas relacionadas à informação, contribuindo com o desenvolvimento de uma abordagem sociocultural no âmbito dos estudos de usuários. Conclui que a Teoria da Prática bourdieusiana auxilia a noção de práticas informacionais no entendimento de que as ações dos indivíduos são conformadas por um embate entre agência e estrutura, interioridade e exteriodade, indivíduo e sociedade, oferecendo importantes contribuiçãoes teórico-conceituais à Ciência da Informação ao reforçar a ideia de que a informação se constitui a partir de sua relação com o indivíduo, e deste com o mundo.

Who’s your mommy? Identifying maternal ancestors of asexual species of Leiolepis Cuvier, 1829 and the description of a new endemic species of asexual Leiolepis Cuvier, 1829 from Southern Vietnam
Authors: GRISMER JESSE L. , GRISMER L. LEE
Published: December 2018

A new asexual species of Leiolepis is described from Binh Chau – Phuoc Buu Nature Reserve, Xuyen Moc district Ba Ria-Vung Tau Province, Vietnam to where it is believed to be endemic. Leiolepis ngovantrii sp. nov. differs from all sexual species of Leiolepis by lacking males and from all asexual species by having nine rows of enlarged keeled scales across the forearm and 37–40 subdigital lamellae beneath the fourth toe. Phylogenetic inference based on 700 base pairs of the mitochondrial ND2 region, placed L. ngovantrii sp. nov. among the currently described asexual species and was used to assess the maternal ancestors of the remaining asexual species. Both maximum parsimony and maximum likelihood analyses recovered L. guttata as the maternal ancestors of L. guentherpetersi, L. boehmei, and L. ngovantrii sp. nov., and L. boehmei as the maternal ancestor to L. triploida.
A new melanistic species of monitor lizard (Reptilia: Squamata: Varanidae) from Sanana Island, Indonesia
Authors: WEIJOLA VALTER S-Å , SWEET SAMUEL S.
Published: December 2018

A new species of monitor lizard endemic to Sanana Island in the northwestern Moluccas is described from a preserved specimen and field observations. This is the only melanistic member of the Varanus indicus species group, and the only taxon in the subgenus Euprepiosaurus with prominent orange-red markings. Allied to Varanus melinus of nearby Mangole and Taliabu islands in body proportions and scutellation, the new species is convergent with melanistic populations of the Varanus salvator complex from the Sula Platform, Sulawesi and Togian Islands. On Sanana the new species reaches highest densities in coastal sago palm swamps, a habitat type that is underutilized by other species in the V. indicus group elsewhere in the Moluccas.

Revision of Eulasia genei Truqui, with description of Eulasia rittneri n. sp. from Israel and synonymic notes on related species (Coleoptera: Scarabaeoidea: Glaphyridae)
Authors: ULIANA MARCO , SABATINELLI GUIDO
Published: December 2018

This paper presents a revision of the species Eulasia genei Truqui, 1848. A total of 773 specimens, including all type series of the involved taxa, were examined. Nominal species currently in synonymy with E. genei are discussed. All the current synonyms proved to be wrongly attributed, and the following new synonyms are proposed: Eulasia pretiosa Truqui, 1848 = E. genei chaifensis (Reitter, 1890) = E. japhoensis (Petrovitz, 1972). Eulasia hybrida agricola (Reitter, 1890) is no longer considered a synonym of E. genei Truqui and Amphicoma genei ab. nobilissima Balthasar, 1929 is an unavailable name. Eulasia rittneri n. sp., a species close to and parapatric to E. genei, is described and illustrated. The diagnostic characters are discussed in relation to their discriminating value, with special consideration for the morphology of the aedeagus. A technique for observing the volumetric shape of the endophallus has been modified and used for the first time as such for the study of Scarabaeoidea. On the basis of the large number of specimens gathered, the distribution range of both species is defined and notes on their ecology and phenology are presented.

Authors: CHAVTUR VLADIMIR G. , BASHMANOV ALEXANDER G.
Published: December 2018

Schornikovoecia eugenyi gen. et sp. nov. of the benthopelagic ostracods of the subfamily Bathyconchoeciinae is established and described, based upon samples collected in the deep-sea zones near the Kurile-Kamchatka Trench and in the Sea of Okhotsk (Kurile Hollow). Most of the specimens have been found at depths over 5000 m. The new genus differs sharply from the currently known genera Bathyconchoecia, Scottoecia, Bathyconchoecetta and Septemoecia of this subfamily in numerous ways: the singular sculpture; the form and structure of the glands on the carapace; the masticatory pad on the mandible; the arming of the fifth limb. The new genus is at present monospecific. Descriptions of the new genus and its new species S. eugenyi sp. nov. are presented.

Two species of the callianassid ghost shrimp genus Neocallichirus Sakai, 1988 are newly recorded from Iran. Neocallichirus darvishi n. sp. appears close to N. jousseaumei (Nobili, 1904), but combined morphological and genetic analyses provide evidence for recognition of the new taxon. Neocallichirus manningi Kazmi & Kazmi, 1992, originally described from Pakistan, is reported for the first time since its original description. A supplemental description and figures are given for N. manningi.
The larvae of Beraeamyia aphyrte Malicky 1972, Beraeamyia kutsaftikii Malicky 1975, and Beraeamyia matsakii Malicky 1980 (Trichoptera: Beraeidae), including a discriminatory matrix to the Greek Beraeidae larvae
Authors: WARINGER JOHANN , MALICKY HANS
Published: December 2018

This paper describes the previously unknown larvae of three Beraeidae species restricted to Greece: Beraeamyia aphyrte Malicky 1972, Bm. kutsaftikii Malicky 1975, and Bm. matsakii Malicky 1980 (Trichoptera: Beraeidae). Information on the morphology of the larvae is given, and the most important diagnostic features are illustrated. The trio of species can be easily separated by an angle present in the dorsal outline of the pronotal carina in Bm. kutsaftikii whereas this dorsal outline is straight in the remaining two species. Finally, the dorsal ridge of the pronotal carina touches the dorsal ecdysial line in Bm. matsakii, but fades far away from the ecdysial line in Bm. aphyrte. With respect to distribution, Bm. kutsaftikii is restricted to the mountains of Central Greece, the Peloponnesos, and the island of Euboea; Bm. matsakii is an endemic of the Ochi mountains in the southern part of Euboea and the island of Andros; and Bm. aphyrte is an endemic of the island of Crete. The species are integrated in a synoptic discriminatory matrix including the currently known Greek Beraeidae larvae. In addition, ecological information on the species is provided.
Discovery of a rare and striking new pierid butterfly from Panama (Lepidoptera: Pieridae)
Authors: NAKAHARA SHINICHI , MACDONALD JOHN R. , DELGADO FRANCISCO , PADRÓN PABLO SEBASTIÁN
Published: December 2018

We here describe and name a distinctive new pierid species in the subfamily Pierinae, Catasticta sibyllae Nakahara, Padrón & MacDonald, n. sp. from western Panama. Catasticta. sibyllae n. sp. is known from only two male specimens collected at two sites which are approximately 130 km apart in western Panama. This new species is the only species in the genus without markings in the median area of both surfaces of forewing and hindwing, and our molecular data suggest that the Peruvian species C. lisa Baumann & Reissinger, 1969 is its sister species.
Overview of the HI-SCALE Field Campaign: A New Perspective on Shallow Convective Clouds

Published: December 2018

Shallow convective clouds are common, occurring over many areas of the world, and are an important component in the atmospheric radiation budget. In addition to synoptic and mesoscale meteorological conditions, land–atmosphere interactions and aerosol–radiation–cloud interactions can influence the formation of shallow clouds and their properties. These processes exhibit large spatial and temporal variability and occur at the subgrid scale for all current climate, operational forecast, and cloud-system-resolving models; therefore, they must be represented by parameterizations. Uncertainties in shallow cloud parameterization predictions arise from many sources, including insufficient coincident data needed to adequately represent the coupling of cloud macrophysical and microphysical properties with inhomogeneity in the surface-layer, boundary layer, and aerosol properties. Predictions of the transition of shallow to deep convection and the onset of precipitation are also affected by errors in simulated shallow clouds. Coincident data are a key factor needed to achieve a more complete understanding of the life cycle of shallow convective clouds and to develop improved model parameterizations. To address these issues, the Holistic Interactions of Shallow Clouds, Aerosols and Land Ecosystems (HI-SCALE) campaign was conducted near the Atmospheric Radiation Measurement (ARM) Southern Great Plains site in north-central Oklahoma during the spring and summer of 2016. We describe the scientific objectives of HI-SCALE as well as the experimental approach, overall weather conditions during the campaign, and preliminary findings from the measurements. Finally, we discuss scientific gaps in our understanding of shallow clouds that can be addressed by analysis and modeling studies that use HI-SCALE data.
Stability Criterion for the Centrifugal Instability of Surface Intensified Anticyclones
Authors: Yim Eunok , Stegner Alexandre , Billant Paul
Published: December 2018

We investigate the linear stability of intense baroclinic anticyclones, with a particular focus on the centrifugal (inertial) instability. Various vertical and radial velocity profiles are studied. The vertical profiles are such that the velocity is maximum at the surface. These profiles correspond to oceanic eddies such as submesoscale mixed-layer eddies or intense mesoscale eddies in the upper thermocline. The results show that the main characteristics of the centrifugal instability (growth rate, vertical wavelength) depend weakly on the baroclinic structure of the anticyclone. The dominant azimuthal wavenumber is for small Burger number (Bu) and for higher Bu, where Bu is the square root of the ratio of the deformation radius over the characteristic eddy radius where the velocity is maximum. The marginal stability limits of the centrifugal instability for the different velocity profiles collapse approximately on a single curve in the parameter space (Ro, Bu), where is the Rossby number, with being the maximum velocity. By means of an asymptotic analysis for short vertical wavelength, an explicit prediction for the marginal stability limit is derived for a wide range of velocity profiles. We then suggest to use, for most of oceanic anticyclones, the instability criterion valid for a Gaussian eddy: where is the Ekman number, H is the eddy depth, and ν is the turbulent viscosity at the ocean surface. Some baroclinic anticyclones can remain stable even if they have a core region of negative absolute vorticity provided that they are small enough. This formula explains the few observations of intense anticyclonic eddies having a negative core vorticity around .
A New Perspective toward Cataloging Northern Hemisphere Rossby Wave Breaking on the Dynamic Tropopause
Authors: Bowley Kevin A. , Gyakum John R. , Atallah Eyad H.
Published: December 2018

Rossby wave breaking (RWB) events are a common feature on the dynamic tropopause and act to modulate synoptic-scale jet dynamics. These events are characterized on the dynamic tropopause by an irreversible overturning of isentropes and are coupled to troposphere-deep vertical motions and geopotential height anomalies. Prior climatologies have focused on the poleward streamer, the equatorward streamer, or the reversal in potential temperature gradient between the streamers, resulting in differences in the frequencies of RWB. Here, a new approach toward cataloging these events that captures both streamers is applied to the National Centers for Environmental Prediction Reanalysis-2 dataset for 1979–2011. Anticyclonic RWB (AWB) events are found to be nearly twice as frequent as cyclonic RWB (CWB) events. Seasonal decompositions of the annual mean find AWB to be most common in summer (40% occurrence), which is likely due to the Asian monsoon, while CWB is most frequent in winter (22.5%) and is likely due to the equatorward shift in mean baroclinicity. Trends in RWB from 1980 to 2010 illustrate a westward shift in North Pacific AWB during winter and summer (up to 0.4% yr−1), while CWB in the North Pacific increases in winter and spring (up to 0.2% yr−1). These changes are hypothesized to be associated with localized changes in the two-way interaction between the jet and RWB. The interannual variability of AWB and CWB is also explored, and a notable modality to the frequency of RWB is found that may be attributable to known low-frequency modes of variability including the Arctic Oscillation, the North Atlantic Oscillation, and the Pacific–North American pattern.

The South Pacific convergence zone (SPCZ) is the largest rainfall feature in the Southern Hemisphere, and is a critical component of the climate for South Pacific island nations and territories. The small size and isolated nature of these islands leaves them vulnerable to short- and long-term changes in the position of the SPCZ. Its position and strength is strongly modulated by El Niño–Southern Oscillation (ENSO), leading to large interannual variability in rainfall across the southwest Pacific including seasonal droughts and pluvials. Currently much of the analysis about SPCZ activity has been restricted to the satellite observation period starting in 1979. Here, the representation of the SPCZ in the Twentieth Century Reanalysis (20CR), which is a three-dimensional atmospheric reconstruction based only on surface observations, is discussed for the period since 1908. The performance of two versions of the 20CR (version 2 and version 2c) in the satellite era is compared with other reanalyses and climate observation products. The 20CR performs well in the satellite era. Extra surface observations spanning the SPCZ region from the longitude of the Cook Islands has improved the representation of the SPCZ during 1908–57 between 20CRv2 and 20CRv2c. The well-established relationship with ENSO is observed in both the representation of mean SPCZ position and intensity, and this relationship remains consistent through the entire 1908–2011 period. This suggests that the ENSO–SPCZ relationship has remained similar over the course of the past century, and gives further evidence that 20CRv2c performs well back to 1908 over the southwest Pacific region.
Revisiting the Birthplace of the Cannabis Social Club Model and the Role Played by Cannabis Social Club Federations

Cannabis Social Clubs (CSCs) are a nonprofit model for the supply of cannabis originating in Spain. This article aims to provide an overview of current CSC practices in Barcelona, exploring the role played by CSC Federations in shaping them. This analysis draws on 32 semistructured interviews with CSC managers ( n = 15) and with other stakeholders in Barcelona ( n = 17). We build also on field observations at other CSCs based in Barcelona. We found a heterogeneity of CSC practices, some of which were not in line with the self-regulatory codes developed by the CSC Federations. In applying an earlier CSC typology, we identified also country-specific CSC features. While the CSC Federations have contributed to unifying the cannabis movement and made efforts to homogenize CSCs’ practices, in the absence of (government) cannabis regulation, their efforts have to some extent been undermined.
Mechanical venous Anastomosis in Head and Neck Microvascular Reconstruction as an Equivalent to the Gold Standard
Authors: Thorpe Eric , Patil Yash
Published: December 2018

To define the most successful and efficient manner to perform venous microvascular anastomoses, the effectiveness of mechanical venous anastomosis in head and neck microvascular reconstruction is reviewed. Head and neck reconstruction with free flap techniques has become the norm and gold standard for large defects. This retrospective, multicenter case series of a single microvascular surgeon's experience with mechanical venous anastomoses specifically assessed the effectiveness of head and neck reconstruction and the complications associated with it. Data were collected from two separate academic centers and are reported from a consecutive series of patients over the course of 10 years. All patients underwent microvascular reconstruction of the head and neck region using venous couplers and flap survival. Flap survival was greater than 98% using mechanical venous couplers as the primary means for venous outflow in this series of 402 consecutive patients and 431 total microvascular flaps. Venous couplers were performed in every instance. The study shows that mechanical venous anastomosis provides a highly effective and efficient means for venous outflow in head and neck microvascular reconstruction, and should be considered equivalent to the gold standard suture technique, even in the most difficult cases.

Sjögren syndrome was chosen as a clinical model to study acinar salivary deficiencies in the development of laryngopharyngeal reflux (LPR). The objective of this prospective cohort study was to compare salivary epidermal growth factor (EGF) concentrations of patients with Sjögren syndrome with and without LPR and gastroesophageal reflux disease (GERD) with normal controls. LPR was diagnosed with positive scores on the Reflux Symptom Index and Reflux and Reflux Finding Score, corroborated by esophagogastroduodenoscopy and/or 24-hour pH-metry. Salivary EGF concentrations of both unstimulated and mechanically stimulated saliva were established using enzyme-linked immunosorbent assay, and the significance level was set at 95%. Twenty-one patients and 19 controls were studied. All patients had LPR and 60% also had GERD. The mean salivary EGF concentration of unstimulated and stimulated saliva in the control group was 1,751.37 pg/ml and 544.76 pg/ml, respectively. Unstimulated and stimulated salivary EGF concentrations in the study group were 2,534.65 pg/ml and 920.69 pg/ml, respectively. These differences were not statistically significant. Body mass index, presence of erosive esophagitis, or severity of hyposalivation did not significantly influence salivary EGF concentrations. LPR and GERD are highly prevalent in patients with Sjögren syndrome. Unlike previous studies in which significant EGF deficiencies were found in patients with reflux laryngitis and GERD, patients with Sjögren syndrome seem to have reflux caused by a decrease in clearance capacity and not in specific salivary components.
Sudden Sensorineural Hearing Loss in Human Monocytic Ehrlichiosis
Authors: Bhalla Vidur , Rodgers Brian , Lin James
Published: December 2018

The hallmarks of symptomatic human monocytic ehrlichiosis (HME) include fever, headache, myalgia, nausea, malaise, transaminitis, and blood cell abnormalities. Previous case reports have described isolated cranial nerve palsies in infected patients but not hearing loss. We describe the onset of sudden sensorineural hearing loss in 2 patients with HME—a 31-year-old woman and an 82-year-old woman. The older patient experienced objective and subjective improvement in her hearing after treatment with an antibiotic and steroid taper; the younger patient was lost to audiologic follow-up. Additionally, we discuss the possible mechanisms of the hearing loss in these patients.

Published: December 2018

We performed a retrospective chart review to compare the presence and types of abnormal muscle tension patterns (MTPs) in patients who had been diagnosed with glottal insufficiency before and after fiberoptic injection laryngoplasty. The main cause of glottal insufficiency had been unilateral vocal fold paralysis. Our review included an analysis of the medical records and laryngeal videostroboscopic recordings of 16 patients—9 men and 7 women, aged 25 to 87 years (mean: 59). Stroboscopic frames were analyzed for the presence of one or more types of abnormal MTP. Statistical analysis was performed to determine the significance of the change in scores for type II and type III MTP before injection and 1 month after injection. Before injection laryngoplasty, 15 of the 16 patients exhibited evidence of an abnormal MTP; 10 patients had MTP II only, 2 had MTP III only, and 3 patients had both. The mean percentage of frames showing MTP (i.e., MTP score) in patients with MTP II was 66.2% before the injection and 28.9% 1 month after; the decrease was statistically significant (p = 0.001). For MTP III, the corresponding figures were 71.6 and 37.7% (p = 0.043). We conclude that injection laryngoplasty has a positive effect on reducing muscle tension in patients with glottal insufficiency.
Granuloma Formation Secondary to Silicone Injection for Soft-Tissue Augmentation in Facial Cosmetics: Mechanisms and Literature Review
Authors: Wang Leo L. , Thomas William W. , Friedman Oren
Published: December 2018

The use of injectable fillers is increasingly popular as an alternative to surgery for facial cosmetic applications. In this regard, silicone is a versatile biomaterial filler that has been used for these purposes, but its use warrants further investigation, especially since it is not clinically approved for such uses. We describe the use of silicone as a facial injectable filler through a scholarly review of the literature for cases of silicone granuloma formation published from September 2007 through September 2017, and we present various contexts in which this complication has been observed. We further review the immunologic etiology of granuloma formation and other complications of silicone injections. We write this report to caution physicians on the use of silicone fillers which, for all their advantages, are associated with significant long-term risks that are frequently overlooked.
Elastography as a Potential Modality for Screening Cervical Lymph Nodes in Patients with Papillary Thyroid Cancer: A Review of Literature
Authors: Saadi Robert , LaRusso Salvatore , Vijay Kanupriya , Goldenberg David
Published: December 2018

Papillary thyroid cancer often presents with cervical lymph node involvement and has a high incidence of recurrence, which requires routine follow-up with ultrasound imaging. Elastography is a novel ultrasound technique that has been demonstrated to be effective clinically in detecting tissue pathology in areas such as the liver and breast. Preliminary data suggest that it may be effective in screening tissues in the neck for malignancy, specifically cervical lymph nodes. However, diagnostic criteria and elastographic techniques vary significantly among the studies we have reviewed, which all tend to focus on populations of patients with many different types of primary malignancies. Further research is required on the feasibility of creating standardized and reproducible clinical criteria in a specific patient population. To study the clinical utility of elastography in cervical lymph nodes, patients with diagnosed papillary thyroid carcinoma may serve as an ideal population because of their need for ultrasound surveillance and the propensity of papillary thyroid cancer to metastasize to and recur in cervical lymph nodes. We will review the limitations, techniques, and reported clinical utility of elastography on cervical lymph nodes and its potential as a screening modality for papillary thyroid cancer.

Published: December 2018

Balloon sinus dilation (BSD) is generally accepted as a safe alternative to traditional sinus surgery. It is a unique technique designed to potentially minimize complications associated with traditional functional endoscopic sinus surgery (FESS). We present a case in which a 65-year-old man experienced a cerebrospinal fluid (CSF) leak in the ethmoid roof that was visualized instantly after balloon dilation in a revision sinus surgery. In this case report, we discuss the causes of CSF leaks and explain in detail the immediate endoscopic repair with a collagen matrix. Also, literature is reviewed on the safety of BSD versus traditional FESS. Postoperative-ly, the patient has been without CSF leak and remains symptom free. CSF leak is a rare but major complication during both FESS and BSD. As BSD use increases, its complication profile will become clearer when used alone, in conjunction with FESS, and/or during revision surgery. Although BSD is considered a benign procedure, one should be cautious when using it in revision sinus surgery.
Policy responses to ‘rough sleepers’: Opportunities and barriers for homeless adults in England
Authors: Dobson Rachael
Published: December 2018

In the winter of 2018, high profile debates about ‘rough sleepers’ intensified following reports about men who died in freezing conditions. Government since pledged to cut the number of rough sleepers by half by 2022 and eliminate it by 2027. This commentary reviews two pieces of legislation which could support this target: the Care Act 2014 and the Homelessness Reduction Act 2018. It argues that policies offer opportunities to improve outcomes for rough sleepers, given historic failings to provide for this social group. However, financial and institutional barriers remain.
