Este estudo investigou as representações sociais de professores de Educação Básica quanto a sua prática docente na utilização das histórias em quadrinhos em sala de aula. Partimos da hipótese de que professores representam a presença dos quadrinhos no ambiente escolar apenas como ferramenta metodológica, desvalorizando o aspecto de ser uma das várias formas de expressão humana, tais como consideramos serem outras manifestações como a literatura, a pintura e a música. Esta desvalorização pode explicar uma subutilização desta expressão artística nos meios educacionais. Para alcançar este objetivo, utilizamos a Teoria das Representações Sociais em articulação com a Teoria da Argumentação. Os resultados mostraram que, a despeito do que dizem as pesquisas acadêmicas sobre quadrinhos e Educação, com exceção de situações e projetos pontuais, constatamos a subutilização do quadrinho em sala de aula. Isso ocorre, em grande parte, por rejeição e desconhecimento do professor. Além disso, os professores representam os quadrinhos em sala de aula apenas como um meio para se alcançar outros objetivos e mesmo as adaptações literárias são meras ferramentas para que o professor leve o aluno ao que ele considera realmente importante, que são as obras que originam essas adaptações. Como nunca houve uma preocupação em entender a representação que os professores têm do uso dos quadrinhos, criou-se uma crença equivocada de que esses projetos são desenvolvidos de forma generalizada nas escolas brasileiras, quando na realidade eles são a exceção e não a regra. Comics in basic education: A study of teachers' social representations This research investigated teachers’ social representations in Basic Education regarding their teaching practice in the use of comics in the classroom. We started from the hypothesis that teachers represent the presence of comics in the school environment only as a methodological tool, devaluing the aspect of being one of the various forms of human expressions, such as we consider other manifestations such as literature, painting and music. This devaluation may explain an underutilization of this artistic expression in the educational field. To achieve this goal, we use the Social Representation Theory in articulation with Argumentation Theory. The results showed that, despite what academic research on comics and education say, except for situations and specific projects, there is an underutilization of the comic in the classroom. This is largely due to teacher rejection and ignorance. In addition, teachers represent comics in the classroom only as a mean to achieve other goals and even literary adaptations are mere tools for the teacher to take the student to what he considers to be really important, which are the works that originate these adaptations. Since there has never been a concern to understand the representation that teachers have of the use of comics, a misconception has been created that these projects are developed in a generalized way in Brazilian schools, when in reality they are the exception and not the rule.

Introduction: Allergic rhinitis (AR) is a disease that affects ≤24% of people in Russia, significantly impairing quality of life (QoL). Intranasal corticosteroids, such as triamcinolone acetonide (TAA), are considered effective drugs for treatment. A post hoc analysis of data (phase III NASANIF trial) examined weekly QoL changes in patients receiving TAA for the treatment of perennial AR (PAR). Methods: NASANIF (NCT03317015) was a double-blind, parallel group, multicenter, prospective, noninferiority, phase III clinical trial. Patients with PAR were randomized (1:1) to receive TAA or fluticasone propionate (FP) for 4 weeks. Here, a post hoc analysis measures QoL using a shortened Rhinoconjunctivitis Quality of Life Questionnaire (miniRQLQ). Differences in miniRQLQ score were evaluated using a mixed linear model and descriptive statistics. A subgroup analysis was performed in patients with a previous diagnosis of allergic conjunctivitis. Results: Of 260 patients eligible for randomization, 128 each completed treatment with TAA or FP. Overall and individual domain scores progressively improved and were significantly different versus baseline at week 4 in both treatment groups: LS mean difference TAA: −30.92 (95% CI [−33.01 to −28.83]), p < 0.001, and FP: −31.13 (−33.23 to −29.04), p < 0.001. In both arms of the subgroup, there was a significant reduction in eye symptoms. There was no significant difference between the TAA and FP treatment groups in any analyses. Conclusions: TAA is effective in improving overall and individual domains of QoL in patients with PAR, over 4 weeks. Patients with a previous diagnosis of allergic conjunctivitis experienced significant improvements in QoL related to the resolution of these symptoms. [ABSTRACT FROM AUTHOR]

Introduction: Allergic rhinitis (AR) is a disease which affects >24% of the population in Russia. Triamcinolone acetonide (TAA) is a corticosteroid used for treating AR. This post hoc analysis assesses the efficacy of intranasal TAA in improving perennial AR (PAR) symptom scores over 4 weeks. Methods: NASANIF (NCT03317015) was a double-blind, parallel-group, multicenter, prospective, non-inferiority, phase III clinical trial in which patients with PAR were randomized (1:1) to receive TAA or fluticasone propionate (FP) over 4 weeks. Our post hoc analysis evaluates weekly change in PAR symptoms using the reflective Total Nasal Symptom Score (rTNSS), overall and for individual symptoms (sneezing, nasal itching, rhinorrhoea, and nasal obstruction). Proportion of patients and time to achieve a ≥50 or ≥75% reduction in rTNSS were assessed. For rTNSS endpoints, a linear mixed-model methodology was used; for time-to-event endpoints, cumulative incidence functions were estimated using the Kaplan-Meier method, in the per-protocol population. Results: Of 260 patients, 128 each completed the study and were randomized to receive TAA or FP. From baseline to week 4, the changes in total rTNSS were −7.78 (95% CI: −8.1701 to −7.3967; p < 0.001) and −7.52 (−7.9053 to −7.1320; p < 0.001) for TAA and FP, respectively. Individual symptoms improved significantly from baseline. The proportion of patients achieving ≥50 and ≥75% reductions in total rTNSS was 88.0 and 67.2%, respectively in the TAA group. No significant differences were observed between the TAA and FP in any analyses. Conclusions: TAA produced effective and prolonged improvement of PAR symptoms over a 4-week treatment period.

This objective of this study was to evaluation of the anticonvulsant effect of Indigofera suffruticosa through the methanol extract of its leaves. Swiss albino mice were subjected to dosages of 100 and 300 mg/kg methanol extract for the study of the anticonvulsant action; the following convulsants were used: pentylenetetrazole (100 mg/kg), picrotoxin (10 mg/kg), strychnine (2 mg/kg), and pilocarpine (600 mg/kg). In the evaluation, 2 mg/kg (ip) diazepam was used as the standard drug in all experimental models and GABAA receptor antagonist Ro 15-1788. The methanol extracts presented excellent anticonvulsant activity, increasing the duration of latency for the beginning of the first seizure in all the tests. The extract in a dose of 300 mg/kg showed its anticonvulsant effect similar to diazepam. The results showed an anticonvulsant activity of I. suffruticosa which can be, at least partly associated with involvement of GABA-BDZ system according to effect demonstrated with Ro 15-1788. Key words: Indigofera suffruticosa, anticonvulsant activity, experimental models, Ro15-1788, mice.

FUNDAMENTO: A disfunção erétil afeta um grande número de homens no mundo e os inibidores de PDE 5 (iPDE5) estão entre os principais métodos de tratamento desses pacientes. O consumo social de álcool e o ato sexual apresentam uma relação considerável. Portanto, a associação entre álcool e iPDE5 pode ocorrer. O carbonato de lodenafila é um novo iPDE5 desenvolvido por uma empresa brasileira. OBJETIVO: Avaliar a repercussão cardiovascular do carbonato de lodenafila, associado ou não ao álcool, assim como as alterações na farmacocinética que esta associação possa determinar. MÉTODOS: Estudo realizado com 15 voluntários sadios que receberam em momentos diferentes o carbonato de lodenafila (CL) na dose de 160 mg em jejum, CL (160 mg) com álcool, ou somente placebo. Esses pacientes foram monitorados por 24 horas, sendo avaliado o quadro clínico, a pressão arterial (PA), a frequência cardíaca (FC), o intervalo QT e também os dados de farmacocinética. RESULTADOS: O carbonato de lodenafila, isoladamente ou associado com álcool, não determinou alterações clínicas significativas na PA ou FC, embora tenha ocorrido diminuição da PA estatisticamente significativa após 4 horas, nos voluntários que receberam medicamento e álcool, assim como um aumento da FC após 6 horas nos pacientes que receberam o CL. A análise do intervalo QT corrigido não mostrou alteração significativa. O álcool aumentou a biodisponibilidade do medicamento em 74%. Houve somente 2 queixas de cefaleia leve, possivelmente associada ao medicamento. CONCLUSÃO: O carbonato de lodenafila, mesmo associado ao álcool, não determinou repercussões clínicas importantes na PA, FC, ou alterações no intervalo QTc; a ingestão com álcool, por sua vez, aumentou significativamente sua biodisponibilidade. BACKGROUND: Millions of men around the world suffer from erectile dysfunction, for which phosphodiesterase 5 inhibitors (PDE-5 inhibitors) are currently the first treatment option. Sexual activity and alcohol consumption are closely related, and the simultaneous use of alcohol and PDE-5 inhibitors can happen. Lodenafil carbonate is a new PDE-5 inhibitor, developed by a Brazilian pharmaceutical company. OBJECTIVE: This work aimed at evaluating the cardiovascular safety of lodenafil carbonate, with and without simultaneous alcohol consumption. METHODS: Fifteen male volunteers received 160 mg lodenafil carbonate (LC), in three different moments. Participants were assigned to three groups, treated with LC in fasting condition, with alcohol or receiving only placebo. The volunteers were continuously monitored during 24 hours for physical impairment, blood pressure, heart rate, QT interval and lodenafil's pharmacokinetic parameters. RESULTS: Lodenafil carbonate alone or with alcohol did not induce clinically relevant modifications in arterial blood pressure or heart rate. A statistically significant decrease in blood pressure was seen four hours after LC and alcohol intake, and an increase in heart rate six hours after intake of lodenafil carbonate alone. The QTc interval was not significantly modified. Lodenafil carbonate bioavailability was increased in 74% when drug intake was associated with alcohol. CONCLUSION: These results show that the use of lodenafil carbonate did not have clinically relevant effects on blood pressure or heart rate, and was not associated with QT interval prolongation. The association of lodenafil carbonate and alcohol affected its pharmacokinetic properties, increasing the bioavailability of the drug. FUNDAMENTO: La disfunción eréctil afecta a un gran número de hombres en el mundo y los inhibidores de PDE5 (iPDE5) están entre los principales métodos de tratamiento de estos pacientes. El consumo social de alcohol y el acto sexual presentan una relación considerable. Por lo tanto, puede ocurrir una asociación entre alcohol e iPDE5. El carbonato de lodenafila es un nuevo iPDE5 desarrollado por una empresa brasileña. OBJETIVO: Evaluar la repercusión cardiovascular del carbonato de lodenafila, asociado o no al alcohol, así como las alteraciones en la farmacocinética que esta asociación pueda determinar. MÉTODOS: Estudio realizado con 15 voluntarios sanos que recibieron en momentos diferentes el carbonato de lodenafila (CL) en la dosis de 160mg en ayunas, CL (160 mg) con alcohol, o solamente placebo. Estos pacientes fueron monitoreados por 24 horas, siendo evaluado el cuadro clínico, la presión arterial (PA), la frecuencia cardíaca (FC), el intervalo QT y también los datos de farmacocinética. RESULTADOS: El carbonato de lodenafila, aisladamente o asociado con alcohol, no determinó alteraciones clínicas significativas en la PA o FC, aunque se haya registrado una disminución de la PA estadísticamente significativa después de 4 horas en los voluntarios que recibieron medicamento y alcohol, así como un aumento de la FC después de 6 horas en los pacientes que recibieron el CL. El análisis del intervalo QT corregido no mostró alteración significativa. El alcohol aumentó la biodisponibilidad del medicamento en un 74%. Se registraron sólo 2 quejas de cefalea leve, posiblemente asociada al medicamento. CONCLUSIÓN: El carbonato de lodenafila, aun asociado al alcohol, no determinó repercusiones clínicas importantes en la PA, FC, o alteraciones en el intervalo QTc; la ingestión con alcohol, a su vez, aumentó significativamente su biodisponibilidad.

OBJETIVO: Os autores descrevem o caso de uma criança do sexo feminino, de 9 anos de idade, com acalasia de esôfago de causa indeterminada, tratada cirurgicamente. Discutem também os métodos empregados para diagnóstico e tratamento, além de realizarem uma revisão da literatura. DESCRIÇÃO: A acalasia do esôfago é uma doença rara em crianças, geralmente de origem indeterminada. Tem como principais sintomas regurgitação, vômitos de características esofágicas, disfagia e perda de peso. O diagnóstico é feito por esofagograma, endoscopia e, mais precisamente, por manometria esofágica. O tratamento de escolha é a cardiomiotomia a Heller, associada ou não a válvula anti-refluxo. A dilatação endoscópica por balão e a toxina botulínica têm sido descritas como alternativas terapêuticas. COMENTÁRIOS: A acalasia de esôfago é uma doença rara em crianças, e sua origem geralmente é indeterminada. O quadro clínico pode ser confundido com doença do refluxo gastroesofágico, podendo retardar seu diagnóstico. A cardiomiotomia a Heller, associada à confecção de válvula anti-refluxo, consiste na modalidade terapêutica de escolha. OBJECTIVE: To report a case of a 9-year-old female presented with esophageal achalasia and approached with surgery. The authors discuss the treatment and make a literature review on the topic. DESCRIPTION: Childhood esophageal achalasia is an unusual disease, often with unknown etiology. The main symptoms are esophageal vomits, dysphagia and weight loss. The diagnosis can be made by esophagogram and endoscopy, but the main examination is the esophageal manometry. Even though the surgical approach is a well-established therapy, some alternative treatments have been used, such as the endoscopy balloon dilatation and the use of botulinum toxin. COMMENTS: Esophageal achalasia is a rare disease in childhood, with unknown etiology. The presentation may be confused with gastroeshophageal reflux, sometimes causing a diagnosis delay. The surgical approach, as well as an antireflux procedure, is the treatment of choice.
