Introduction  Chronic maxillary atelectasis (CMA) is characterized by a persistent decrease in the maxillary sinus volume due to inward bowing of its walls. According to its severity, it may be classified into three clinical-radiological stages. Objective  To report a case of stage II CMA associated with subclinical visual field defect. Case Report  A 34-year-old woman presented with a 15-year history of recurrent episodes of sinusitis and intermittent right facial discomfort for the past 5 years. She denied visual complaints, and no facial deformities were observed on physical examination. Paranasal sinus computed tomography (CT) demonstrated a completely opacified right maxillary sinus with inward bowing of its walls, suggesting the diagnosis of stage II CMA. A computerized campimetry (CC) disclosed a scotoma adjacent to the blind spot of the right eye, indicating a possible damage to the optic nerve. The patient was submitted to functional endoscopic sinus surgery, with drainage of a thick mucous fluid from the sinus. She did well after surgery and has been asymptomatic since then. Postoperative CT was satisfactory and CC was normal. Discussion  CMA occurs because of a persistent ostiomeatal obstruction, which creates negative pressure inside the sinus. It is associated with nasosinusal symptoms but had never been described in association with any visual field defect. It can be divided into stage I (membranous deformity), stage II (bony deformity), and stage III (clinical deformity). The silent sinus syndrome is a special form of CMA. This term should only be used to describe those cases with spontaneous enophthalmos, hypoglobus, and/or midfacial deformity in the absence of nasosinusal symptoms.

O objetivo do estudo foi verificar o consumo de sal e alimentos ricos em sódio e a pressão arterial de escolares de uma escola da rede privada e de outra da rede pública, em Barra do Ribeiro, no Estado do Rio Grande do Sul. Trata-se de um estudo transversal. Foram realizadas medidas antropométricas e de pressão arterial, seguindo métodos padronizados. Os responsáveis pelos escolares responderam questionário com questões referentes às condições socioeconômicas, fatores de risco familiares para hipertensão e hábitos alimentares do escolar (questionário de frequência). Foram avaliados 81 escolares, 42 (51,90%) com idade média 8,3 ± 3,2 anos. Dentre os escolares, 45 (55,60%) eram da rede privada e 36 (44,40%), da rede pública. Foram encontrados dois escolares com hipertensão arterial sistólica e ambos eram da escola da rede pública (p= 0,194); no entanto, o achado pode ter sido casual. Fato seme-lhante pode ter ocorrido com os quatro escolares com hipertensão arterial diastólica; desses, três eram da rede privada. Porém, não houve diferença significativa entre os grupos (p= 0,625). O consumo médio de sal foi de 7,66g (3098,81 mg da Na ou 133,86 mEq). O alimento rico em sódio correlacionado a níveis elevados de pressão arterial sistólica foi o enlatado. Constatamos que, quanto maior o consumo de sal, maior a pressão arterial sistólica. Nessa população, o consumo médio de sal encontra-se acima do recomendado pela literatura atualmente.

This article verifies the consumption of salt and food rich in sodium and the blood pressure of schoolchildren of a private and a public school in the city of Barra do Ribeiro, Rio Grande do Sul State, Brazil. It is a cross-sectional study with standardized methods of anthropometric and blood pressure measures. Parents and tutors answered a questionnaire about socio-economic conditions, family risk factors regarding hypertension and feeding habits of the student (frequency questionnaire). 81 students were evaluated, from those 42 (51.90%) medium age were 8.3 ± 3.2 years. 45 (55.60%) studied in the private school and 36 (44.40%) in the public school. Findings show two children with systolic hypertension, both from the public school (p = 0.194), yet this may be found by chance. Similar fact may have occurred with the four cases of diastolic hypertension; being three of them from the private school. But there was not significant difference between the groups (p = 0.625). The medium consumption of salt found in this population was of 7.66g (3098.81 mg or 133.86 mEq), which is above the recommended in the present literature. Canned food was related to be rich in sodium and to be associated with high levels of systolic blood pressure. In conclusion, as higher the salt consumption, higher the systolic blood pressure.

O objetivo dessa pesquisa foi avaliar a atividade antimicrobiana de duas pastas experimentais, contendo própolis associada a hidróxido de cálcio, contra culturas polimicrobianas coletadas de 16 molares decíduos necrosados e com fístulas extraídos de crianças entre 4 e 6 anos de idade de ambos os sexos. A técnica de difusão em ágar foi utilizada para determinar a atividade antimicrobiana das seguintes pastas: (1) 11,0% extrato etanólico de própolis + hidróxido de cálcio e (2) 11,0% extrato de própolis sem álcool + hidróxido de cálcio. A associação de hidróxido de cálcio com propilenoglicol foi utilizada como o grupo de controle positivo (CHP). Testes estatísticos de Friedman and Wilcoxon foram empregados para comparar dados do crescimento das zonas de inibição (p<0,05). Pasta 1 e Pasta 2 apresentaram zonas de inibição maiores contra os microrganismos coletados dos canais radiculares do que CHP (p=0,021 e 0,003 respectivamente). A Pasta 2 mostrou zonas de inibição um pouco mais largas que a Pasta 1 (p=0,053). A associação entre própolis e hidróxido de cálcio foi efetiva no controle de infecções dentárias in vitro.

The purpose of this study was to evaluate the antimicrobial activity of two experimental pastes containing propolis extract associated with calcium hydroxide against polymicrobial cultures collected from 16 necrotic and fistulae root canals in primary molars of 4-8-year-old children of both sexes. The agar-well diffusion technique was used to determine the antimicrobial activity of the following pastes: 11.0% ethanolic extract of propolis (EEP) + calcium hydroxide; and 11.0% extract of propolis without ethanol (EP) + calcium hydroxide. EEP, EP and the association of calcium hydroxide and propylene glycol (CHP) was used as the positive control groups, and propylene glycol was used as a negative control group. Friedman and Wilcoxon tests were used to compare the data from the microbial growth inhibition zones (p<0.05). Paste 1 and Paste 2 showed larger growth inhibition zones against microorganisms from root canal samples than CHP (p=0.021 and 0.003, respectively). Paste 2 tended to have larger growth inhibition zones than Paste 1 (p=0.053). The association between propolis and calcium hydroxide was effective in controlling dental infections in vitro.
