Published: May 2018

A elevada variabilidade ambiental das áreas cultivadas é um dos fatores preponderantes na produção e qualidade dos produtos agrícolas, sendo essencial à avaliação de genótipos adaptados às diversas situações edafoclimáticas a fim de se obter rendimentos satisfatórios. Diante do exposto, um experimento foi desenvolvido, no período de setembro a novembro de 2014, no município de São Bento, Paraíba, situado na microrregião do Alto Sertão paraibano, com o objetivo de avaliar o comportamento produtivo e a qualidade dos frutos de genótipos de melancieira. Os tratamentos (genótipos de melancieira - BGCIA 863, BGCIA 864, Crimson Sweet e Crimson Select de polpa vermelha, e BGCIA 865, BGCIA 866 de polpa amarela) foram distribuídos em blocos casualizados, com quatro repetições. As variáveis analisadas foram massa média de frutos, produtividades total, comercial e não comercial e as perdas de produção de frutos. Também avaliaram-se os aspectos físicos (diâmetro longitudinal, diâmetro equatorial, índice de formato e espessura da casca) e físico-químicos (teor de sólidos solúveis e acidez titulável na polpa dos frutos). Os genótipos de polpa vermelha, exceto o Crimson Sweet, superam os de polpa amarela na massa dos frutos, produtividade total e comercial e com menores perdas da produção obtida. Para as condições ambientais de São Bento, no alto Sertão do estado da Paraíba, é indicado o cultivo dos genótipos de polpa vermelha (BGCIA 863, BGCIA 864, Crimson Sweet e Crimson Select) em relação aos de polpa amarela (BGCIA 865 e BGCIA 866).

Authors: Azdy Rezania Agramanisti , Rini Arsia
Published: May 2018

Layanan pengaduan yang dimiliki oleh Perguruan Tinggi umumnya hanya menjadikan mahasiswa sebagai fokus utama dalam peningkatan layanan, hal ini dikarenakan mahasiswa adalah pengguna langsung jasa yang ditawarkan oleh Perguruan Tinggi. Layanan pengaduan tidak memfasilitasi pengaduan yang mungkin dapat diberikan oleh pengguna jasa lainnya, seperti pengguna lulusan atau masyarakat sasaran kegiatan pengabdian masyarakat yang dilakukan oleh dosen Perguruan Tinggi tersebut. Penelitian ini bertujuan membangun sebuah aplikasi berbasis web yang dapat digunakan seluruh pengguna jasa Perguruan Tinggi untuk melakukan pengaduan. Pembangunan aplikasi menerapkan metodologi rekayasa perangkat lunak agar dapat menghasilkan perangkat lunak tepat waktu. Metodologi yang digunakan adalah Extreme Programming. Hasil dari penelitian menunjukkan bahwa penerapan Extreme Programming pada pengembangan aplikasi mengakibatkan pengembangan dapat dilakukan secara cepat dengan jumlah anggota tim yang minimal. Pengembangan dapat dilakukan dengan cepat karena pengembangan aplikasi dimulai dengan membangun komponen yang paling sederhana terlebih dahulu, yaitu komponen verifikasi akun, yang dilanjutkan dengan komponen lainnya. Hasil pengujian menggunakan metode black box aplikasi dapat dijalankan sebagaimana mestinya dan memenuhi acceptance criteria pada user story. AbstractThe complaint service system owned by College generally only focuses on the students in the improvement of services, this is because students are the direct users of the services offered by the College.

Hand-Grip Strength: Normative Reference Values and Equations for Individuals 18 to 85 Years of Age Residing in the United States
Authors: Wang Ying-Chih , Bohannon Richard W. , Li Xiaoyan , Sindhu Bhagwant , Kapellusch Jay
Published: May 2018

Background

Hand-grip strength is an indicator of overall strength and a predictor of important outcomes. Up-to-date, population-specific reference values for measurements of grip strength are needed to properly interpret strength outcomes.

Objectives

To provide population-based grip-strength reference values and equations for US residents 18 to 85 years of age.

Methods

Hand-grip data from 1232 participants 18 to 85 years of age were extracted from the database of the 2011 normative phase of the US National Institutes of Health Toolbox project in this cross-sectional study. Descriptive reference values and equations were derived from the data.

Results

The authors present grip-strength reference values using summary statistics (mean, standard deviation, and percentile). The mean grip strength ranged from 49.7 kg for the dominant hand of men 25 to 29 years of age to 18.7 kg for the nondominant hand of women 75 to 79 years of age. The researchers also present reference regression equations for the dominant and nondominant sides of men and women. The explanatory variables in the equations are age, height, and weight.

Conclusion

The normative reference values and equations provided in this study may serve as a guide for interpreting grip-strength measurements obtained from tested individuals. J Orthop Sports Phys Ther 2018;48(9):685–693. Epub 23 May 2018. doi:10.2519/jospt.2018.7851

Background

The Photograph Series of Daily Activities-short electronic version (PHODA-SeV) assesses perceived harmfulness of daily activities in patients with low back pain (LBP). Although there is some evidence that the PHODA-SeV is a reliable and valid tool, its psychometric properties have not been fully investigated.

Objectives

To investigate the test-retest reliability, measurement error, interpretability, construct validity, and internal and external responsiveness of the PHODA-SeV in patients with chronic LBP.

Methods

Ninety-one patients were included in the analysis for this prospective cohort study. For reliability purposes, the PHODA-SeV was administered twice, with a 1-week interval before beginning treatment. Pain, disability, and measures of pain-related fear (ie, PHODA-SeV, Fear-Avoidance Beliefs Questionnaire [FABQ], and Tampa Scale of Kinesiophobia [TSK]) were collected before and after the 8-week treatment period.

Results

The PHODA-SeV showed excellent reliability (intraclass correlation coefficient model 2,1 = 0.91), without evidence of ceiling and floor effects. The construct validity analysis demonstrated fair correlations (r = 0.25–0.50) of the PHODA-SeV with the FABQ, but no correlation with the TSK (r<0.25). For internal responsiveness, the PHODA-SeV showed an effect size of 0.87 and a standardized response mean of 0.92, interpreted as a large effect (greater than 0.80). For external responsiveness, the correlations between the PHODA-SeV and changes in the TSK and FABQ were considered low, and the receiver operating characteristic curve analyses revealed an area under the curve lower than the proposed threshold of 0.70.

Conclusion

The PHODA-SeV is a reliable tool that can detect changes over time in pain-related fear in patients with chronic LBP undergoing physical therapy treatment. This tool, however, failed to identify those patients who did or did not improve, according to other pain-related fear measures. J Orthop Sports Phys Ther 2018;48(9):719–727.

Bài báo trình bày kết quả khảo sát lượng chất thải rắn (CTR) sinh hoạt phát sinh, thành phần CTR được chôn lấp ở Bãi chôn lấp thành phố Đông Hà và ước tính lượng khí nhà kính phát thải từ bãi chôn lấp. Từ mẫu CTR lấy ở 50 hộ thuộc 9 phường trong 2 đợt, hệ số phát sinh CTR sinh hoạt ở Đông Hà được xác định là 0,66 kg/người/ngày. Hệ số phát sinh CTR khác nhau có ý nghĩa thống kê giữa các phường, nhưng không khác nhau giữa các hộ có quy mô khác nhau. Kết quả 3 đợt phân tích mẫu CTR tại bãi chôn lấp cho thấy tỷ lệ thành phần hữu cơ dễ phân hủy khá thấp (45,7%) trong khi một số thành phần không có giá trị tái chế như vải sợi, da và cao su khá cao; có thể do các thành phần hữu cơ và có giá trị đã được giữ lại để tái sử dụng và tái chế. Phát thải khí nhà kính từ bãi chôn lấp Đông Hà, ước tính theo mô hình IPCC (2006), tăng dần từ năm 2012 (84 tấn CH4 hay 2109 tấn CO2e) đến 2017 (433 tấn CH4 hay 10.833 tấn CO2e) theo sự gia tăng lượng CTR chôn lấp ở bãi.  Các kết quả thu được là hữu ích cho công tác quy hoạch, quản lý CTR của thành phố Đông Hà, đặc biệt theo hướng giảm thiểu biến đổi khí hậu.
Ustawa o związkach metropolitalnych. Skuteczny instrument rozwoju czy zbędna legislacja?
Authors: Łysoń Artur
Published: May 2018

Działalność gospodarcza jednostek samorządu terytorialnego jest tematem kontrowersyjnym. Wątpliwości dotyczą przede wszystkim zakresu prowadzenia przez samorząd komercyjnej działalności gospodarczej. Z jednej strony podkreśla się, że samorząd, jako podmiot dysponujący dochodami publicznymi, nie musi sztywno trzymać się ekonomicznego bilansu zysków i strat oraz nie ponosi ryzyka gospodarczego. Z drugiej strony jednostka taka, prowadząc działalność gospodarczą, może uzyskiwać środki finansowe, które będą przeznaczane na realizację jej zadań własnych, czyli zaspokajanie potrzeb wspólnoty samorządowej. Jest to tym ważniejsze, im bardziej nieracjonalnie skonstruowany jest system finansowania działalności samorządu terytorialnego. Artykuł przybliża teoretyczno-prawną problematykę prowadzenia działalności gospodarczej przez jednostki samorządu terytorialnego oraz praktykę funkcjonowania tych uregulowań na przykładzie Wrocławia.
Solidarny Wrocław 2030. O kapitale społecznym w nowej strategii miasta
Authors: Medeksza Łukasz
Published: May 2018

W najnowszej strategii Wrocławia, przyjętej w 2018 r., lokalne władze zapowiadają decentralizację ustrojową miasta. Za warunek powodzenia tego planu uważają jednoczesne wzmacnianie solidarności między mieszkańcami. Powiązanie solidarności z decentralizacją ma być nowym sposobem na podtrzymanie wzrostu kapitału społecznego. Problem jednak w tym, że władze Wrocławia już nie raz zapowiadały decentralizację ustrojową – i nic z tego nie wynikało. Z kolei lokalne wskaźniki kapitału społecznego powoli rosną, ale od lat są raczej niskie. Autor artykułu opisuje najnowsze dzieje idei decentralizacji i wzmacniania kapitału społecznego w strategicznych dokumentach Wrocławia i Dolnego Śląska. Rekonstruuje ideowy rodowód tego typu pomysłów. Zastanawia się nad przyczynami fiaska dotychczasowych prób decentralizacji miasta, ale wskazuje też tendencje, które sprzyjają jej obecnie.
Jakie dzielnice? Dylematy narodzin krakowskiego samorządu 1989–1991
Authors: Purchla Jacek
Published: May 2018

U schyłku I Rzeczypospolitej – w wyniku przyjętych w 1791 roku przez Sejm Wielki dwóch doniosłych ustaw o miastach królewskich – podjęto proces administracyjnego scalenia średniowiecznego trójmiasta wraz z otaczającymi je jurydykami. Był to równocześnie koniec nadanego Krakowowi w roku 1257 systemu magdeburskiego i „wyjście” miasta extra muros. Kolejne podziały Krakowa na dzielnice, ich kształt i kompetencje, były nie tylko funkcją ekspansji terytorialnej miasta, ale zostały też w dużej mierze zdeterminowane przez zmieniające się w ciągu XIX i XX wieku systemy polityczne. Nowy podział administracyjny Krakowa stał się w roku 1990 jedną z fundamentalnych kwestii w toczącej się wówczas gorącej debacie o przyszłości miasta i o kształcie odradzającego się nad Wisłą samorządu. Była to wówczas z wielu powodów kwestia precedensowa w skali Polski.

Artykuł opowiada o prowadzonych w latach 2015-2016 pracach nad koncepcjami dalszego rozwoju Wrocławia. W ich trakcie powstały scenariusze przyszłości miasta, które zakładały różne kierunki trendów społecznych, ekonomicznych i politycznych. Diagnozowany był bieżący stan głównych obszarów życia Wrocławia, w tym grożące im ryzyka. Analizowane były rozmaite pomysły na sprofilowanie miasta. Badania opinii społecznej pokazały, że mieszkańcom najbardziej podobają się trzy takie śmiałe wizje przyszłości: Wrocław jako jeden z pięciu wiodących ośrodków nauki i kultury w Europie Środkowej; Wrocław jako najlepsze i najpiękniejsze w Europie miasto-ogród; Wrocław jako Dolina Krzemowa Europy Środkowej. Dwa główne projekty, które przysłużyły się tym wszystkim badaniom i analizom to Foresight Społeczny Wrocław 2036/2056 oraz Strategia Wrocław 2030. Artykuł pokazuje związki między nimi.

Published: May 2018

We characterised Lancefield group B streptococcal (GBS) isolates causing invasive disease among non-pregnant adults in Portugal between 2009 and 2015. All isolates (n = 555) were serotyped, assigned to clonal complexes (CCs) by multilocus sequence typing and characterised by surface protein and pilus island gene profiling. Antimicrobial susceptibility was tested by disk diffusion and resistance genotypes identified by PCR. Overall, serotype Ia was most frequent in the population (31%), followed by serotypes Ib (24%) and V (18%). Serotype Ib increased significantly throughout the study period (p < 0.001) to become the most frequent serotype after 2013. More than 40% of isolates clustered in the CC1/alp3/PI-1+PI-2a genetic lineage, including most isolates of serotypes Ib (n = 110) and V (n = 65). Erythromycin and clindamycin resistance rates were 35% and 34%, respectively, both increasing from 2009 to 2015 (p < 0.010) and associated with CC1 and serotype Ib (p < 0.001). The Ib/CC1 lineage probably resulted from acquisition of the type Ib capsular operon in a single recombination event by a representative of the V/CC1 macrolide-resistant lineage. Expansion of the new serotype Ib/CC1 lineage resulted in increased macrolide resistance in GBS, causing invasive disease among adults in Portugal. The presence of this clone elsewhere may predict more widespread increase in resistance.
Process and outcome indicators for infection control and prevention in European acute care hospitals in 2011 to 2012 – Results of the PROHIBIT study
Authors: Hansen Sonja , Schwab Frank , Zingg Walter , Gastmeier Petra ,   the PROHIBIT study group
Published: May 2018

Introduction

Hospitals from 24 European countries were asked for information on infection prevention and control (IPC) indicators as part of the Prevention of Hospital Infections by Intervention and Training (PROHIBIT) survey. Methods: Leading IPC personnel of 297 hospitals with established healthcare-associated infection (HCAI) surveillance provided information on local surveillance and feedback by using a questionnaire. Results: Most hospitals focused on bloodstream infection (BSI) (n = 251) and surgical site infection (SSI) (n = 254), with a SSI post-discharge surveillance in 148 hospitals. As part of the HCAI surveillance, meticillin-resistant Staphylococcus aureus (MRSA) was the leading multidrug-resistant organism (MDRO) under surveillance. Seventy-nine per cent of hospitals (n = 236) monitored alcohol-based hand rub (ABHR) consumption. Feedback to the local IPC committees mainly included outcome data on HCAI (n = 259; 87%) and MDRO among HCAI (n = 245; 83%); whereupon a feedback of MDRO data depended on hospital size (p = 0.012). Discussion/conclusion: Objectives and methods of surveillance vary across Europe, with BSI, SSI and MRSA receiving considerably more attention than indicators such as pneumonia and urinary tract infection, which may be equally important. In order to maximise prevention and control of HCAI and MDRO in Europe, surveillance should be further improved by targeting relevant HCAI. The role of feedback should be explored in more detail.

We report a multidrug-resistant Neisseria gonorrhoeae urogenital and pharyngeal infection with ceftriaxone resistance and intermediate resistance to azithromycin in a heterosexual woman in her 20s in France. Treatment with ceftriaxone plus doxycycline failed for the pharyngeal localisation. Whole-genome sequencing of isolate F90 identified MLST1903, NG-MAST ST3435, NG-STAR233, and relevant resistance determinants. F90 showed phenotypic and genotypic similarities to an internationally spreading multidrug-resistant and ceftriaxone-resistant clone detected in Japan and subsequently in Australia, Canada and Denmark.
Exergy and Exergoeconomic Assessment of Tehran’S Waste to Energy Power Plant
Authors: Behzadi Amir Mohammad , Houshfar Ehsan , Habibollahzade Ali , Gholamian Ehsan , Ashjaee Mehdi
Published: May 2018

Converting municipal waste into energy through the Waste-to-Energy (WtE) technology has been growing fast during the past decades. Besides the considerable reduction in the waste volume, it can generate steam and/or electricity. In the present work, energy, exergy, and exergoeconomic analysis techniques are used to investigate the performance of Tehran’s 3 MW WtE plant. In the exergoeconomic analysis, the exergy cost of the stream, annual capital investment, and operating and maintenance costs are analyzed. Combination of economic principle and exergy analysis has been used to minimize the power generation costs. MSW is converted to a high enthalpy syngas via gasification to produce the required heat for steam generation in a Rankine power cycle. The effect of different inlet parameters is investigated on the target variables: net produced work, exergy efficiency, and power cost rate. Also, the exergy destruction and the exergetic efficiency of every component is calculated to assess the irreversibilities in the system. Results show that the gasifier has the highest exergy destruction. The overall exergy and energy efficiencies are 14.49% and 17.27%, respectively. Additionally, by increasing the turbine inlet pressure, the power cost rate will decrease and the net produced work and the overall system efficiency increases. It is further realized that the moisture content and gasification temperature have an indirect effect on the exergy efficiency of the gasifier.

Published: May 2018

Em 280 apendicectomias realizadas em 21 meses, foram diagnosticados incidentalmente 2 casos de tumores neuroendócrinos em mulheres com 12 e 89 anos. Ambas foram sujeitas a apendicectomia urgente por clínica de apendicite aguda com 12 horas e 5 dias de evolução respetivamente sem mais sintomatologia. O diagnóstico histológicoda primeira doente foi tumor neuroendócrino com 2 mm de diâmetro e localização incomum, o corpo do apêndice. Na segunda doente um tumor de 1,5 cm no apex. Em ambas, dada a localização, o tamanho tumoral e margens livres, a apendicectomia foi curativa. Da análise dos dados e segundo a literatura, verificou-se que estes tumores são os mais frequentes no apêndice, ocorrendo principalmente em mulheres e com localizações mais comuns no apex e base seguindo-se o corpo.

Authors: Furtado Ana Bastos , Martinho Aurélia , Revés Luís , Freitas Paulo Telles
Published: May 2018

Introdução: A mediastinite aguda é um processo inflamatório dos tecidos que envolvem as estruturas mediastínicas. É uma patologia pouco frequente e com elevada taxa de mortalidade se não for diagnosticada e tratada atempadamente. Realizou-se uma revisão dos casos de mediastinite aguda internados no Serviço de Medicina Intensiva, focando os aspetos demográficos da amostra, etiologia, cuidados prestados e mortalidade associada.Material e Métodos: Análise descritiva retrospetiva da informação constante em processo de todos os doentes internados no Serviço de Medicina Intensiva com o diagnóstico mediastinite, entre 1 de abril de 1996 e 31 de dezembro de 2014.Resultados: A análise incidiu sobre 13 doentes, 54% do género feminino, com média de idade 69 anos. As etiologias obtidas: perfuração do esófago (n=5); mediastinite descendente (n=5); secundária a infeções de outras localizações (n=2); infeção de esternotomia por cirurgia cardíaca (n=1). À admissão no Serviço de Medicina Intensiva 38% encontravam-se em sépsis e 38% em choque séptico. Todos realizaram tomografia computorizada (n=13). Todos foram tratados com antibioterapia, 85% com técnicas cirúrgicas e com 15% técnicas minimamente invasivas. As complicações foram localizadas maioritariamente ao espaço pleural e pulmão (n=7). A mortalidade foi de 15,4%.Conclusão: A nossa série difere do reportado na literatura relativamente aos dados demográficos (mulheres, com idade média superior) e à etiologia das mediastinites (perfuração do esófago e mediastinites descendentes). Para o sucesso do tratamento é fundamental o diagnóstico e abordagem atempada em ambiente de cuidados intensivos pela gravidade, complexidade e multiplicidade das técnicas aplicadas.

Inibidores de immune checkpoint são uma promessa na luta contra o cancro do pulmão e outros tumores malignos, alterando o microambiente do tumor e bloqueando a evasão ao sistema imunitário. Dois anticorpos anti-PD-1, nivolumab e pembrolizumab, estão aprovados para uso clínico, no cancro do pulmão, doença avançada em segunda linha. Anticorpos PD-L1 tal como atezolizumab e MEDI-4736 estão em desenvolvimento clínico e são alvo atual de vários estudos de fase II/III inclusivamente a decorrer em Portugal; tratamento de segunda linha em doentes com cancro do pulmão de não pequenas células doença avançada tem tido até agora como opção padrão o docetaxel.

Desde a publicação dos resultados do National Lung Screening Trial (NLST) em 2011, o rastreio do cancro do pulmão com tomografia computorizada de dose baixa tem sido o centro da investigação, guidelines e discussão geral deste tema. O racional para o screening tem evoluído nos últimos anos, dado que hospitais e outros sistemas de saúde ganharam experiência na implementação de programas de rastreio. O screening também mostra a importância do tabagismo, não apenas como um fator de risco para o cancro, mas também como uma variável que pode afetar drasticamente os resultados do cancro. Estas foram, entre outras, questões discutidas por Especialistas no 2016 ASCO Annual Meeting - American Society of Clinical Oncology, que decorreu em Chicago de 3 a 7 de junho de 2016.

INTRODUÇÃO: O envelhecimento crescente da população e a necessária gestão de doentes cada vez mais complexos numa sociedade onde se esperam melhores resultados do ponto de vista custo-efetividade tem exigido aos serviços de saúde uma visão necessariamente mais multidisciplinar das especialidades.MÉTODOS: Neste artigo apresenta-se uma breve casuística de três meses da articulação direta diária entre ortopedistas e internistas, assentes numa prestação de cuidados integrados aos doentes internados por causas ortopédicas mas com necessidade de gestão de comorbilidades e/ou intercorrências significativas. Aborda-se ainda o protocolo das fraturas proximais do fémur criado por uma equipa de trabalho interdisciplinar no sentido de prestar melhores cuidados a uma situação ortopédica associada a considerável morbimortalidade.RESULTADOS: Na maioria dos casos os doentes estavam internados em contexto de patologia traumática e foram submetidos a tratamento cirúrgico. Destacaram-se a elevada faixa etária, a diversidade de comorbilidades, o número importante de infeções nosocomiais e a necessidade de gestão médica multidisciplinar. A maioria dos doentes exigiu acompanhamento regular.CONCLUSÃO: A perceção de doentes com elevado número de comorbilidades e outras entidades nosológicas a par do problema ortopédico salienta a necessidade de um acompanhamento mais holístico, onde certamente a Medicina Interna pode exercer um papel fundamental.

INTRODUÇÃO: Os tumores de células germinativas são tumores raros, constituindo 1% a 2% do total das neoplasias malignas e cerca de 5% do total dos tumores malignos urológicos. Originam-se no testículo em mais de 90% dos casos.MÉTODOS: Os autores reveem os casos de tumores de células germinativas, incluindo o diagnóstico, tratamento e follow-up, ocorridos no Hospital CUF Infante Santo num período de mais de 15 anos, compreendido entre agosto de 1999 e novembro de 2014.RESULTADOS: A série compreende 33 doentes, todos submetidos inicialmente a orquidectomia radical, diagnóstica e terapêutica, estando o maior número de doentes, 21 (63,6%) em estádio I. Destes, 14 (66% dos estádios I), vieram a fazer tratamento pós-orquidectomia. Todos os doentes em estádios mais avançados efetuaram tratamento pós-cirúrgico. Verificaram-se apenas quatro recidivas (12,1%), ocorridas em mediana 20 meses pós-diagnóstico e todas salvas por posterior tratamento.CONCLUSÃO: A toxicidade parece-nos aceitável, não tendo ocorrido nenhuma morte relacionada com qualquer modalidade de tratamento. Com uma mediana de follow-up de 59 meses à data da conclusão da revisão, a sobrevivência livre de doença foi de 100%.
Carcinoma Ductal Invasor da Mama: Marcação Axilar Prévia ao Tratamento Neoadjuvante. Caso Clínico e Revisão da Literatura
Authors: Viana Charlène , Rios Hugo , Barros Nuno , Castro Luís , Rocha Maria José , Ferreira Arlindo
Published: May 2018

Nos doentes com cancro da mama, o tratamento neoadjuvante tem um papel fundamental na diminuição do tamanho do tumor, possibilitando uma cirurgia conservadora, sem um aumento significativo da recorrência local. Estudos mais recentes revelaram também um impacto significativo do tratamento neoadjuvante na erradicação da doença axilar. Apresentamos o caso de uma mulher de 46 anos com carcinoma ductal invasor e com doença axilar comprovada histologicamente. Após marcação de ambas as lesões com material radiopaco, a doente iniciou quimioterapia neoadjuvante seguida de cirurgia conservadora. A biópsia seletiva de gânglio sentinela revelou a ausência de células neoplásicas assim como a peça de tumorectomia, ambas marcadas previamente. O tratamento neoadjuvante associado à marcação prévia das lesões permitiu a realização de uma cirurgia conservadora com uma resposta completa ao tratamento, para além de evitar o esvaziamento axilar.

Síndrome de Schnitzler: Entidade Clínica a ser Considerada em Doentes com Urticária Crónica
Authors: Carvoeiro Ana Catarina , Silva Sérgio , Sampaio António , Leite Alberto , Couto Mariana , Bettencourt Paulo
Published: May 2018

INTRODUÇÃO: A divulgação de condições clínicas raras, em que a intervenção médica modifica significativamente a abordagem dos doentes, é importante, pois, além de alertar para a sua existência, permite a partilha de conhecimento com potencial impacto na prática clínica.CASO CLÍNICO: Doente do sexo masculino, com 32 anos de idade, previamente avaliado em Dermatologia e Imunoalergologia por urticária crónica. Refere aparecimento de rash urticariforme crónico acompanhado de astenia e artralgias, com oito anos de evolução. Medicado com anti-histamínicos e ciclosporina sem resolução da sintomatologia. Foi referenciado a Medicina Interna por aumento persistente e crescente da velocidade de sedimentação (65 mm). No estudo dirigido efetuado, identificou-se uma gamapatia monoclonal IgM de cadeias kappa. Diagnosticou-se o doente, como tendo síndrome de Schnitzler. Iniciou  terapêutica com colquicina com resolução completa dos sintomas.DISCUSSÃO: A síndrome de Schnitzler é uma entidade rara, cuja patofisiologia não se encontra completamente compreendida, sabendo-se que apresenta um perfil autoinflamatório. O diagnóstico da síndrome de Schnitzler exige elevada suspeição clínica, pelo que a descrição de casos como o apresentado é crucial, para que esta seja uma entidade conhecida e discutida, com uma maior notoriedade.

Cefaleia Pós-Punção Lombar Diagnóstica por Cefaleia Persistente
Authors: Santana Marta Pinheiro Tenreiro , Araújo António
Published: May 2018

A complicação mais frequente da punção lombar é a cefaleia pós-punção lombar, que decorre da depleção do líquido cefalorraquidiano e surge nos primeiros cinco dias após a punção lombar. Destaca-se pelo seu caráter postural e distribuição frontal-occipital. Reporta-se o caso clínico de uma doente de 33 anos que desenvolve cefaleia pós-punção lombar diagnóstica. Uma vez que se trata de um procedimento recorrente na prática clínica, torna-se fulcral aplicar diligências técnicas e de seleção de material, de forma a reduzir a incidência da síndrome pós-punção lombar. Embora a sua evolução seja geralmente benigna, existem complicações sérias associadas à persistência de baixas pressões do líquido cefalorraquidiano, pelo que requer vigilância clínica e imagiológica.

“To Let it Be Without Pretense”
Authors: Lundberg Mattias
Published: May 2018

This article examines the use of canonic, fugal, and imitative writing in progressive rock, with special emphasis on the interaction between received models of composition and the apparent trialing and struggles to utilize, appropriate, and reinterpret such models in a popular, commercial, and performance-mediated idiom. While the reception history of progressive rock has hitherto mainly focused on the concepts of “pretension” (the appropriation of elements from the Western classical tradition) and “contention” (the countercultural social critique of cultural, musical, and political establishments), the music considered here illustrates problems of contention not just against the establishment but also within the counterculture itself, through both emblematic qualities of learned writing (surface allusions to counterpoint) and functional applications of received and appropriated counterpoint traditions (structural use of counterpoint).
Form, Diversity, and Lack of Fulfillment in the First Movement of Schumann’sFantasieop. 17
Authors: Ponce Adriana
Published: May 2018

This paper presents a new interpretation of the first movement of Schumann’sFantasieop. 17 that combines formal function and expressive gesture. It offers a brief critique of previous interpretations, and presents a reading based on simultaneous conflicting designs, a number of fluid sections that change functions as they move toward and away from points of stability, and an overall narrative that arises from repeated denials of the kind of fulfillment associated with normative dynamic curves.
The Concept of Mutability in Russian Theory
Authors: Bakulina Ellen
Published: May 2018

In the last several decades, some important studies, such as those by Christopher Lewis, Harald Krebs, William Kinderman, and William Rothstein, have explored alternatives to monotonality in tonal music. In this paper, I discuss the concept ofperemennost’(mutability), which addresses the same problem from a Russian perspective. Mutability is generally defined as a fluctuation between two diatonically related tonal centers, usually a third apart. However, this somewhat narrow definition does not capture the notion in all its richness; the concept of mutability evolved significantly over the course of the last century. I explore this concept in the writings of six twentieth-century Russian theorists: Boleslav Iavorskiĭ, Lev Mazel, Viktor Berkov, Igor Sposobin, Iuriĭ Kholopov, and Andrei Miasoedov.
Performing Expressive Closure in Structurally Open Contexts: Chopin’s Prelude in A minor and the Last Two Dances of Schumann’sDavidsbündlertänze
Authors: Hatten Robert S.
Published: May 2018

Schenkerian analysis gives priority to structural harmonic and voice-leading closure in tonal works, but composers have found other ways to simulate (and dissimulate) structural closure for dramatically expressive purposes. After a brief look at an example by Beethoven (the coda to the first movement of op. 2, no. 1), I focus on interpreting closure in two Romantic piano pieces. In his Prelude in A minor, op. 28, no. 2, Chopin plays with three different closural gambits: dissolution to silence, a false Picardy third close on the dominant, and a final V7–i cadence in A minor. The latter two options are also marked by shifts in level of discourse, and may suggest two commentaries (beatific consolation vs. tragic desolation) on the funereal trajectory of the work. In the penultimate dance of hisDavidsbündlertänzeop. 6, Schumann achieves both thematic and tonal closure, complete with the cyclic return of waltz no. 2 and a passionately tragic coda suggestive of Florestan. But he expressively undercuts that strong closure to allow Eusebius the last word. The final waltz (no. 18) overflows not only its own formal boundaries, but also the formal closure of the set implied by no. 17, reversing the tragic coda to achieve a transcendently positive epiphany. I propose and illustrate performance options that can help project the expressive closural dramas in these two works by Chopin and Schumann.
Treading Robert Schumann’s New Path
Authors: Krebs Harald
Published: May 2018

Robert Schumann’s late songs (1849–52) are in some respects difficult to understand and to perform. Paradoxically, it is their apparent simplicity that poses a challenge for performers; harmonically, texturally, and metrically less adventurous than the songs of 1840, they may on first contact seem rather bland. Those who wish to explore Schumann’s “second practice” of song writing must grapple with the questions: 1) What is interesting and expressive about the late songs? and 2) How can their interesting and expressive elements be communicated to listeners?

One striking aspect of the songs is their manner of declaiming the texts; their vocal rhythms depart more drastically from the poetic rhythm than is ever the case in Schumann’s earlier songs. Poetic feet, which would be approximately equivalent in duration in a normal recitation, are set to a wide variety of durations, producing irregular and unpredictable vocal rhythms. Schumann’s new manner of declamation is a significant locus of expression in songs where other potentially expressive features are attenuated. Analysis and recomposition highlight Schumann’s unorthodox but expressive declamation, and help performers to make decisions that enhance the song’s expressive attributes.
Scale Systems and Large-Scale Form in the Music of Yes
Authors: Clement Brett G.
Published: May 2018

This article explores the relationship between diatonic modal systems and form in the music of the progressive-rock band Yes. Within, I discuss the band’s approach to scalar modulation, referencing key signatures and the concept of scalar voice leading. The study concludes with the analysis of four extended pieces by Yes, which demonstrates the applicability of the theoretical modal to matters of large-scale tonality and formal articulation.
Hacking the Music Theory Classroom
Authors: Duker Philip , Gawboy Anna , Hughes Bryn , Shaffer Kris P.
Published: May 2018

This article focuses on three “hacks” to the traditional model of music theory instruction:standards-based grading(SBG),just-in-time teaching(JiTT), andthe inverted classroom. In SBG, students receive multiple grades in reference to clearly defined learning objectives rather than a single grade that may mask weaknesses by averaging them with strengths. JiTT assesses students’ understanding before class so that the instructor can adjust the lesson plan according to their needs. In the inverted classroom, students acquire a basic understanding of the material outside of class so that class time may be used for active engagement rather than lecture. These tools and the technologies that support them have the potential to help strengthen curricula, increase the impact that an instructor can have on undergraduate theory students, and in some cases reduce the amount of time an instructor must devote to achieving that impact. Any one of these hacks can be incorporated within an otherwise traditional music theory course and can work together synergistically. Both their modularity and their compatibility give them potential to increase instructor efficiency and effectiveness in a wide range of class settings. After describing the scholarly literature surrounding the three hacks as they have been incorporated in a variety of academic disciplines, the authors present four testimonials describing how the three hacks have been incorporated into four diverse music programs: a traditional school of music within a large state university, a large private institution with a focus on jazz and commercial music, a department of music in a mid-sized university, and a small, private university with music classes that combine theory and aural skills.
“That Awkward Scale”: Verdi, Puccini, and theScala enigmatica
Authors: Burke (submitted by L. Poundie Burstein) Richard
Published: May 2018

On August 5, 1888, theGazzetta musicale di Milanochallenged its readers to harmonize a curious scale that it had received from a famous Bolognese musician. Two weeks later, the journal’s editors published several commendable solutions, including one by the scale’s inventor, Adolfo Crescentini. TheGazzetta’s“scala-rebus” (or scale-puzzle) would likely have been forgotten were it not for the fact that Verdi wrote his own solution (not published in the journal), which formed the basis for hisAve Mariaand later found its way into hisQuattro Pezzi Sacri. This article examines several solutions to the “scala-rebus,” focusing especially on Verdi’s. Yet it goes even further, proposing that Crescentini’s scale inspired not only Verdi but also Puccini. The opening measures of Puccini’sToscabear striking similarities to the “scala-rebus,” suggesting that in composing this opera Puccini was making use of one of his favorite compositional strategies: returning to old material—in this case, to a curious puzzle that may well have preoccupied him twelve years earlier.
