ABSTRACT OBJECTIVE To estimate the evolution of the prevalence of SARS-CoV-2 virus infection among residents aged 18 years or over in the municipality of São Paulo. METHODS This is a population-based household survey conducted every 15 days, between June and September 2020, and January and February 2021. In total, the study comprised 11 phases. The presence of antibodies against SARS-CoV-2 was identified in venous blood using a lateral flow test, Wondfo Biotech. In the last phase, the researchers combined it with an immunoenzymatic test, Euroimmun. The participants also answered a semi-structured questionnaire on sociodemographic and economic factors, and on social distancing measures. Prevalence estimates and the 95% confidence interval were estimated according to regions, Human Development Index, sex, age group, ethnicity, education, income, and variables associated with risk or prevention of infection. To compare the frequencies among the categories of each variable, the chi-square test with Rao-Scott correction was used, considering a significance level of 5%. RESULTS In total, 23,397 individuals were interviewed and had their samples collected. The estimated prevalence of antibodies against SARS-CoV-2 ranged from 9.7% (95%CI: 7.9–11.8%) to 25.0% (95%CI: 21.7–28.7). The prevalence of individuals with antibodies against the virus was higher among black and brown people, people with lower schooling and income, and among residents of regions with lower Human Development Index. The lowest prevalences were associated with recommended measures of disease protection. The proportion of asymptomatic infection was 45.1%. CONCLUSION The estimated prevalence of the infection was lower than the cumulative incidence variation, except for the last phase of the study. The differences in prevalence estimates observed among subpopulations showed social inequality as a risk of infection. The lower prevalence observed among those who could follow prevention measures reinforce the need to maintain social distancing measures as a way to prevent SARS-CoV-2 infection.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

Apesar de rara, a pneumoconiose reumatoide, também chamada de síndrome de Caplan, pode ser diagnosticada entre trabalhadores expostos à sílica e entre pacientes com silicose, pneumoconiose dos mineiros de carvão e asbestose. A maior prevalência ocorre entre os silicóticos, apesar de ter sido descrita inicialmente em mineiros de carvão com pneumoconiose. O achado que define o tipo clássico da síndrome é a presença de nódulos reumatoides nos pulmões, independente da presença ou não de pequenas opacidades pneumoconióticas, ou de grandes opacidades de fibrose pulmonar maciça, associada ou não a um quadro de artrite reumatoide em atividade. Relatamos o caso de uma mulher com quadro de artrite reumatoide, diagnosticada 34 anos após exposição à sílica livre em uma indústria de porcelana por 7 anos, apresentando radiograma de tórax com opacidades arredondadas de 1 a 5 cm de diâmetro, distribuídas na periferia de ambos os pulmões. A biópsia transtorácica guiada por TC de um dos nódulos revelou tratar-se de nódulo reumatoide com macrófagos em paliçada, típico da síndrome de Caplan. São discutidos aspectos de diagnóstico da síndrome, classificação e ocorrência, ressaltando a importância da anamnese ocupacional em casos de artrite reumatoide com opacidades radiológicas pulmonares.

Although rare, rheumatoid pneumoconiosis, also known as Caplan's syndrome, can occur in workers exposed to silica, as well as in patients with silicosis, coal workers' pneumoconiosis or asbestosis. Prevalence is higher among patients with silicosis, despite the fact that it was originally described in coal workers with pneumoconiosis. The classical finding that defines this syndrome is that of rheumatoid nodules in the lungs, regardless of whether there are small rounded opacities suggestive of pneumoconiosis or large opacities consistent with massive pulmonary fibrosis, with or without clinical rheumatoid arthritis. We describe the case of a female patient with rheumatoid arthritis, diagnosed 34 years after 7 years of occupational exposure to silica at a porcelain plant. A chest X-ray showed circular opacities of 1-5 cm in diameter, bilaterally distributed at the periphery of the lungs. A CT-guided thoracic punch biopsy of one of those nodules revealed that it was rheumatoid nodule surrounded by a palisade of macrophages, which is typical of Caplan's syndrome. Aspects of diagnosis, classification and occurrence of this syndrome are discussed, emphasizing the importance of the occupational anamnesis of patients with rheumatoid arthritis and lung opacities on chest X-rays.

Objetivo: Observar os efeitos da fratura experimental de corpo de mandíbula no crescimento da maxila e mandíbula. Métodos: Utilizando ratos com um mês de idade. Estes foram distribuídos em dois grupos: experimental, onde foi efetuada a fratura de corpo de mandíbula à direita, e controle-operado, no qual foi realizado apenas o acesso cirúrgico. Aos três meses de idade foi realizada a eutanásia e após a maceração, a mandíbula foi desarticulada. O crânio foi submetido à incidência radiográfica axial e as hemi-mandibulas à incidência radiográfica lateral. Com base nestas, foram feitas mensurações cefalométricas por meio de um sistema de computador e os valores submetidos a análises estatísticas. Resultados: O comprimento da maxila, bem como a altura e o comprimento da mandíbula apresentaram diferença significante a menor para o lado direito, no grupo experimental. No grupo controle-operado houve diferença significante a menor para o comprimento da porção posterior da maxila e para a altura e comprimento da mandíbula para o lado direito. O grupo experimental quando comparado ao grupo controle-operado mostrou ser significativamente menor em todas as mensurações da maxila e mandíbula para ambos os lados, com exceção do comprimento da mandíbula. Conclusão: A fratura de corpo da mandíbula, bem como a abordagem cirúrgica, tiveram efeitos negativos no crescimento da maxila e da mandíbula.

Objective: The purpose of this study was to observe the effects of experimental fracture of the mandibular body on the growth of maxilla and mandible, by using one-month-old rats. Methods: These were distributed into two groups: experimental, which underwent a fracture of the right mandibular body, and sham-operated, which underwent the surgical access only. The animals were sacrificed at three months of age and, after dissection, the mandible was disarticulated. The skull was submitted to axial radiograph and the hemimandibles to a lateral radiograph. With these, cephalometric mensurations were made through a computer system, and the obtained values submitted to statistical analyses. Results: The length of the maxilla, as well as the height and length of the mandible presented significant difference with decrease to the right side, in the experimental group. In the sham-operated group there was significant difference with decrease to length of posterior part of the maxilla and to height and length of the mandible on the right side. The experimental group when compared to the sham-operated group was significantly lesser in all the mensurations of maxilla and mandible to both sides, except in mandibular length. Conclusion: It was concluded that fracture of the mandibular body, as well as the surgical access, had negative effects on growth of maxilla and mandible.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

São relatados quatro casos de esquistossomose do sistema nervoso central, descrevendo-se os achados radiológicos e sua correlação com a clínica. Em um caso o envolvimento cerebral foi caracterizado por lesão pseudotumoral única, com confirmação anatomopatológica, e três casos de esquistossomose medular foram caracterizados por tumefação medular e impregnação leptomeníngea e radicular do meio de contraste paramagnético. Os achados deste trabalho enfatizam a importância de se considerar a esquistossomose no diagnóstico diferencial de lesões encefálicas ou medulares em pacientes procedentes de áreas endêmicas para a esquistossomose.

We report four cases of patients with schistosomiasis in the central nervous system and describe and correlate the radiologic findings with clinical manifestations. In one patient, cerebral involvement presented as a pseudotumoral lesion confirmed by autopsy. Three other patients had schistosomiasis in the spinal cord characterized by an intramedullary mass and radicular and leptomeningeal enhancement after administration of gadolinium. Our findings show the importance of considering schistosomiasis in the differential diagnosis of intramedullary or cerebral lesions in patients of endemic areas of schistosomiasis.

Os efeitos da fratura unilateral do arco zigomático no crescimento facial foram avaliados através de mensurações cefalométricas. Fratura com desvio medial no lado direito foi realizada em ratos com um mês de idade. Os animais foram sacrificados com três meses de idade e sua mandíbula foi desarticulada. O crânio foi submetido à tomada radiográfica axial e as hemimandíbulas à norma lateral. As mensurações foram realizadas através de um sistema de computador. Foi verificada diferença significante a menor para a altura do corpo e do ramo da mandíbula. Não houve diferença significante para a profundidade da fossa infratemporal, bem como para as diversas mensurações na maxila e para o comprimento mandibular. A tendência de retorno do arco zigomático com desvio à sua posição original foi confirmada.

The effect of unilateral zygomatic arch fracture on facial growth was analysed by means of cephalometric measurements. Medially displaced fracture of the right side was achieved in one month old rats. Reaching three months the animals were sacrified, and their mandibles disarticulated. The skull was submitted to axial radiographic incidence and the hemimandibles to a lateral radiographic incidence. The measurements were made through a computer system. Significant differences were verified with a decrease in body height and ramus of the mandible. There was no significant difference in infratemporal fossae depth, as well as in diverse measurements in maxilla and in mandibular lenght. The tendency of the fractured arch to return to its original position was confirmed.

O comportamento da fratura do arco zigomático no período de crescimento foi avaliado através de mensurações cefalométricas. Fratura com desvio medial no lado direito foi realizada em ratos com um mês de idade. Foi verificada tendência de retorno do arco fraturado à sua posição original, porém, com diferença estatisticamente significante para a profundidade da fossa infratemporal. Entretanto, não houve diferença significante para a distância entre o arco zigomático e a mandíbula, o que pode ser explicado pela presença de desvio significante da mandíbula.

The behavior of the zygomatic arch fracture in the growth period was analyzed by means of cephalometric measurements. Medially displaced fracture of the right side was provoked in one-month-old rats. There was a tendency of the fractured arch to return to its original position, but with statistically significant differences as to the depth of the infratemporal fossa. However, there was no significant difference regarding the distance between zygomatic arch and mandible, which can be explained by the presence of significant deviation of the mandible.
