Swiss stained-glass panels: an analytical study

The history and iconography of Swiss stained glass dating between the 16th and 18th centuries are well studied. However, the chemical and morphological characteristics of the glass and glass paints, particularly the nature of the raw materials, the provenance of the glass, and the technology used to produce it are less well understood. In this paper, we studied two sets of samples from stained-glass panels attributed to Switzerland, which date from the 16th to 17th centuries: the first set comes from Pena National Palace collection, the second from Vitrocentre Romont. The aims were to identify the materials used in the production of the glass, to find out more about their production origin and to characterize the glass paints. Both glass and the glass paints were analysed by particle-induced X-ray emission; the paints were additionally analysed by scanning electron microscopy–electron-dispersive X-ray spectroscopy (SEM-EDS). The results show that the glass from both sets was probably produced in the same region and that wood ash was used as a fluxing agent. Different recipes have been used to make the blue enamels. However, the cobalt ore used as a coloring agent in all of the blue enamels came from the mining district in Schneeberg, Germany

Delayed epistaxis secondary to intracavernous pseudoaneurysm of internal carotid artery

Post-traumatic pseudoaneurysm of the internal carotid artery is a very rare but potentially fatal cause of epistaxis. Early diagnosis is essential for an adequate management of this entity. The authors present a case of pseudoaneurysm of the internal carotid artery that developed massive epistaxis six months after skull base trauma.Pseudoaneurisma traumático da artéria carótida interna é uma causa rara de epistaxe, porém potencialmente fatal. O diagnóstico precoce é essencial para um adequado manejo da patologia. Os autores relatam um caso de pseudoaneurisma da carótida interna que se apresentou como epistaxe maciça após seis meses de trauma craniano prévio.Hospital do Servidor Público do Estado de São Paulo Serviço de Otorrinolaringologia/Cabeça e PescoçoUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaUNIFESP, EPMSciEL

Subglottic stenosis as a clinical manifestation of Wegener's granulomatosis in adolescents: report of a case and review of literature

Wegener's Granulomatosis is a well-characterized systemic vasculitis and necrotising granulomatous inflammation of the upper, lower respiratory tracts and the kidneys. The initial manifestations of the disease usually occur in patients over than twenty years old. The otolaryngologic symptoms like rhinorrhea, recurrent sinusitis and epistaxis are commonly present in early course of the disease. It seems that subglottic stenosis is correlated to Wegener's granumatosis in adolescents. We describe a case of a patient that developed subglottic stenosis associated with Wegener's granulomatosis in childhood during the course of the disease.A Granulomatose de Wegener é uma patologia caracterizada por vasculite sistêmica e inflamação granulomatosa necrotizante que compromete o trato respiratório alto, pulmões e rins, cujas manifestações iniciais, na maioria das vezes, ocorre em maiores de 20 anos de idade. As queixas clínicas otorrinolaringológicas estão, com freqüência, presentes nas fases iniciais da doença, sendo rinite, sinusopatia de repetição e epistaxe as mais comuns. A estenose subglógica parece estar correlacionada com a Granulomatose de Wegener em adolescentes. Relatamos o caso de uma paciente portadora de Granulomatose de Wegener cujo início dos sintomas foi na infância, tendo evoluído com estenose laríngea durante o curso da doença.Hospital do Servidor Público do Estado de São Paulo Serviço de Otorrinolaringologia/Cabeça e PescoçoFaculdade de Medicina de São Paulo Divisão de Clínica OtorrinolaringológicaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaUNIFESP, EPMSciEL

Long noncoding intronic RNAs are differentially expressed in primary and metastatic pancreatic cancer

<p>Abstract</p> <p>Background</p> <p>Pancreatic ductal adenocarcinoma (PDAC) is known by its aggressiveness and lack of effective therapeutic options. Thus, improvement in current knowledge of molecular changes associated with pancreatic cancer is urgently needed to explore novel venues of diagnostics and treatment of this dismal disease. While there is mounting evidence that long noncoding RNAs (lncRNAs) transcribed from intronic and intergenic regions of the human genome may play different roles in the regulation of gene expression in normal and cancer cells, their expression pattern and biological relevance in pancreatic cancer is currently unknown. In the present work we investigated the relative abundance of a collection of lncRNAs in patients' pancreatic tissue samples aiming at identifying gene expression profiles correlated to pancreatic cancer and metastasis.</p> <p>Methods</p> <p>Custom 3,355-element spotted cDNA microarray interrogating protein-coding genes and putative lncRNA were used to obtain expression profiles from 38 clinical samples of tumor and non-tumor pancreatic tissues. Bioinformatics analyses were performed to characterize structure and conservation of lncRNAs expressed in pancreatic tissues, as well as to identify expression signatures correlated to tissue histology. Strand-specific reverse transcription followed by PCR and qRT-PCR were employed to determine strandedness of lncRNAs and to validate microarray results, respectively.</p> <p>Results</p> <p>We show that subsets of intronic/intergenic lncRNAs are expressed across tumor and non-tumor pancreatic tissue samples. Enrichment of promoter-associated chromatin marks and over-representation of conserved DNA elements and stable secondary structure predictions suggest that these transcripts are generated from independent transcriptional units and that at least a fraction is under evolutionary selection, and thus potentially functional.</p> <p>Statistically significant expression signatures comprising protein-coding mRNAs and lncRNAs that correlate to PDAC or to pancreatic cancer metastasis were identified. Interestingly, <it>loci </it>harboring intronic lncRNAs differentially expressed in PDAC metastases were enriched in genes associated to the MAPK pathway. Orientation-specific RT-PCR documented that intronic transcripts are expressed in sense, antisense or both orientations relative to protein-coding mRNAs. Differential expression of a subset of intronic lncRNAs (<it>PPP3CB</it>, <it>MAP3K14 </it>and <it>DAPK1 loci</it>) in metastatic samples was confirmed by Real-Time PCR.</p> <p>Conclusion</p> <p>Our findings reveal sets of intronic lncRNAs expressed in pancreatic tissues whose abundance is correlated to PDAC or metastasis, thus pointing to the potential relevance of this class of transcripts in biological processes related to malignant transformation and metastasis in pancreatic cancer.</p

Educação, currículo escolar e protagonismo juvenil: os desafios da educação na contemporaneidade

Resumo: Este artigo se insere no debate sobre educação e política, abordando a relação entre educação, currículo escolar e violência simbólica na perspectiva de adolescentes entre 12 e 17 anos que cumprem medidas socioeducativas no CREAS (Centro de Referência Especializada da Assistência Social) de Vitória, Brasil. Através de nossas análises, percebemos que a educação apresenta desafios, contradições e tensões decorrentes principalmente da organização da sociedade contemporânea, que acaba por reforçar a exclusão desses alunos. Além disso, apontamos a discrepância entre a regulamentação dessas medidas e o cotidiano escolar bem como a falta de protagonismo dos sujeitos envolvidos no cumprimento dessas medidas como alguns obstáculos do processo de inclusão desses adolescentes. Palavras-chave: Educação; Currículo Escolar; Protagonismo Juvenil e Violência.   Resumen: Este artículo se inserta en el debate sobre educación y política, con un enfoque en la relación entre educación, plan de estudios y violencia simbólica en la perspectiva del adolescente entre 12 y 17 años que cumple una “medida socioeducativa” en el CREAS (Centro de Referência Especializado de la Asistencia Social) de Vitória, Brasil. Mediante nuestros análisis percibimos que la educación presenta desafíos, contradicciones y tensiones derivadas principalmente de la organización de la sociedad contemporánea, que refuerza la exclusión. Además, señalamos la discrepancia entre la regulación de la medida, y el cotidiano escolar, así como la falta de protagonismo de los sujetos involucrados en el cumplimiento de las medidas como algunos obstáculos del proceso de inclusión de estos adolescentes. Palabras clave: Educación; Plan de Estudios; Protagonismo Juvenil y Violencia.   Abstract: The theme of this article is inserted in the debate on education and politics in a way that relates education, curriculum and symbolic violence in the perspective of adolescents at the age range of 12 to 17 years who are under socio-educational measures in the CREAS (Specialized Center of Reference in Social Work) of Vitoria, Brazil. Throughout some analysis we realized that education presents challenges, contradictions and tensions mainly due to the organization of contemporary society, which reinforces exclusion. In addition, we identified the discrepancy between the regulation of these measures and the school routine, and the lack of leadership of the individuals complying with the measures as some of the obstacles these adolescents face in the social inclusion process.

COVID-19 and mental health of pregnant women in Ceará, Brazil

OBJECTIVE To assess the perceptions of pregnant women about COVID-19 and the prevalence of common mental disorders during the implemented social distancing period. METHODS This was an observational, cross-sectional study using digital media, of pregnant women exposed to social distancing due to the COVID-19 pandemic, in Fortaleza, Ceará, Northeastern Brazil. Common mental disorders were estimated using the modified Self-Report Questionnaire-20 (SRQ-20) scale, and the feelings towards COVID-19 were assessed using the Fear of COVID-19 scale through telephone calls made in May 2020. COX multivariate regression models were used to verify the associations. RESULTS Of the 1,041 pregnant women, 45.7% (95%CI: 42.7–48.8) had common mental disorders (CMD). All items of the Fear of COVID-19 Scale showed a significant association with the prevalence of CMD (p &lt; 0.001). A CMD risk gradient was observed, going from a prevalence ratio of 1.52 (95%CI: 1.13–2.04) in pregnant women with two positive items to 2.70 (95%CI: 2.08–3.51) for those with four positive items. Early gestational age and the lack of prenatal care were also associated with CMD. CONCLUSIONS The prevalence of common mental disorders in pregnant women was high during the period of social distancing and was aggravated by negative feelings towards COVID-19

Encefalite de Rasmussen: avaliação de resultados depois da cirurgia

BACKGROUND AND PURPOSE: Rasmussen Encephalitis (RE) is characterized by intractable epilepsy, progressive hemiparesis and unilateral hemispheric atrophy. The progression of the symptoms usually occurs within months to few years. Antiepileptic drugs are usually not effective to control disease progression and epilepsy surgery in the form of hemispheric disconnection has been considered the treatment of choice. This work describes the clinical and electrographic analyses, as well as the post-operative evolution of patients with RE. PATIENTS AND METHODS: This work includes all the patients with RE evaluated from January 1995 to January 2008 by the Ribeirão Preto Epilepsy Surgery Program (CIREP) considering demographic data, interictal and ictal electroencephalographic (EEG) findings; anatomo-pathological findings and clinical outcome. RESULTS: Twenty-five patients were evaluated, thirteen were female. Mean age of epilepsy onset was 4.4±2.0 years. There were no differences between patients with slow and fast evolution with respect to age of epilepsy onset (p=0.79), age at surgery (p=0.24), duration of epilepsy (0.06), and follow-up (p=0.40). There were no correlations between the presence of bilateral EEG abnormalities or the absence of spikes and post-operative seizure outcome (p=0.06). Twenty-three patients underwent surgery. The mean follow-up was 75.3 months. Eleven patients had total seizure control. Twelve individuals persisted with seizures consisting of mild facial jerks (6 patients), occasional hemigeneralized tonic-clonic seizures (3 patients), and frequent tonic-clonic seizures (3 patients). Mental and language impairment was observed in 15 and 12 patients, after surgery, respectively. CONCLUSIONS: This retrospective study reported the clinical and electrographic analysis, as well as the evolution of 23 patients with RE. Fourteen patients achieved satisfactory seizure control, three patients had partial response to surgery, and five patients had maintenance of the pre-operative condition. All patients with left side involvement presented with some language and cognitive disturbance.INTRODUÇÃO E OBJETIVOS: A Encefalite de Rasmussen (ER) é caracterizada por epilepsia intratável, hemiparesia progressiva e atrofia hemisférica unilateral. A progressão dos sintomas geralmente ocorre em meses ou poucos anos. As drogas antiepilépticas são usualmente ineficazes no controle da progressão da doença e o tratamento cirúrgico, com desconexão hemisférica tem sido considerado o tratamento de escolha. Neste trabalho descreveremos os achados clínicos e eletrográficos, assim como a evolução pós-operatória de pacientes com ER. PACIENTES E MÉTODOS: foram incluídos todos os pacientes com ER avaliados no período de janeiro de 1995 a janeiro de 2008, no Centro de Cirurgia de Epilepsia de Ribeirão Preto (CIREP), sendo considerados os dados demográficos, os achados do eletrencefalograma (EEG) interictal e ictal, resultado anatomo-patológico e o seguimento clínico. RESULTADOS: Vinte e cinco pacientes foram avaliados, 13 eram do sexo feminino. A idade média de início da epilepsia foi de 4.4±2.0 anos. Não houve diferenças significativas entre os pacientes com evolução lenta ou rápida considerando-se a idade de início da epilepsia (p=0,79), idade da cirurgia (p=0,24), duração da epilepsia (p=0,06) e tempo de seguimento (p=0,40). Não houve correlação entre a presença de alterações bilaterais ou ausência de descargas ao EEG e o seguimento pós-operatório (p=0,06). Vinte e três pacientes foram submetidos à cirurgia. O tempo médio de seguimento foi de 75,3 meses. Onze pacientes evoluíram com controle total das crises. Doze pacientes permaneceram com crises que consistiram de clonias faciais sutis (6 pacientes), crises tônico-clônicas hemigeneralizadas ocasionais (3 pacientes) ou crises tônico-clônicas frequentes (3 pacientes). Alterações cognitivas e de linguagem foram observadas em 15 e 12 pacientes após a cirurgia, respectivamente. CONCLUSÕES: este estudo retrospectivo relatou os achados clínicos, eletrográficos e a evolução de 23 pacientes. Controle satisfatório das crises foi obtido em 14 pacientes. Três pacientes tiveram resposta parcial com a cirurgia e cinco pacientes mantiveram o quadro pré-operatório. Todos os pacientes com envolvimento do hemisfério cerebral esquerdo evoluíram com distúrbio de linguagem e cognitivo.(FAEPA) USP - Hospital das Clínicas da Faculdade de Medicina de Ribeirão PretoCNPqFAEP
