Aim To determine the prevalence of dental development anomalies and type of influence on the smile of adolescent students. Method This was a cross-sectional and analytical study carried out in two public (A1) and two private (A2) schools chosen by lot in the city of Parnaíba-Piauí. The sample calculation was based on the target population: number of people enrolled in public and private schools between 15 and 19 years, in the city of Parnaíba-PI, which totaled 6209 students in 2020, according to a survey carried out by the Brazilian Institute of Geography and Statistics – IBGE. A questionnaire on epidemiological data and aesthetic self-perception of the smile was applied to 160 adolescents between 15 and 19 years old, from August 2020 to July 2021. The clinical examination was carried out under natural light, to check for the presence of anomaly(s) in the dental development. Students who presented only one pathology would be called group 1 (G1), those who presented two would be called group 2 (G2) and those who presented 3 or more would be called group 3 (G3). On the other hand, adolescents in whom no anomaly was evidenced would participate in the control group (CG), both in A1 and A2. Results It was observed that 37.5% of the sample had only a type of dental anomaly, corresponding to 60 individuals. The most prevalent were enamel hypoplasia, fusion, transposition, agenesis, ectopic eruption, microdent and dens-in-dent. It was possible to verify a higher prevalence in the maxilla, private schools (76.6%) and females (86.6%). In 45% of adolescents with dental anomalies, embarrassment was observed when smiling. Conclusion The prevalence was relatively high, highlighting the enamel hypoplasia, influencing the smile esthetics of a reasonable number of adolescents, whether for acquaintances, strangers or even for photographs.

Abstract: En | Text: En | PDF: En

ABSTRACT Variation in rainfall affects crops; therefore, agricultural practices become essential for forage production in semi-arid regions. This study aimed to evaluate the influence of different agricultural practices on phyllochron, structural characteristics of forage cactus and millet, and their relations with crop yield using the principal component analysis (PCA). The design was in randomized blocks, with six treatments: sole cropped cactus without straw mulching, sole cropped cactus with straw mulching, sole cropped millet without straw mulching, sole cropped millet with straw mulching, and cactus intercropping with millet, with and without straw mulching, each with four replicates. There were three cactus cycles and nine millet cycles (three cycles of cultivars BRS1501 and six of IPA Bulk-1-BF). Biometric parameters were evaluated monthly, while yield was determined after the crop harvest. Phyllochron was determined with the regression analysis. The PCA was applied to structural characteristics and yield. The systems adopted did not influence the structural characteristics of cactus and millet ( p > 0.05), except for cladode thickness, which increased with straw mulching. Phyllochron of the millet reduced when the crop was intercropped. The structural characteristics of cladode length, width, and thickness influenced crop yield, mainly in systems with straw mulching. Straw mulching and intercropping alter phyllochron of cactus and millet. The adoption of straw mulching has a more significant relationship with cactus yield, whereas biometric variables influence crop yield for millet, not the cropping system.

Abstract Background Major advances have been seen in techniques and devices for performing percutaneous coronary interventions (PCIs) for chronic total occlusions (CTOs), but there are limited real-world practice data from developing countries. Objectives To report clinical and angiographic characteristics, procedural aspects, and clinical outcomes of CTO PCI performed at dedicated centers in Brazil. Methods Included patients underwent CTO PCI at centers participating in the LATAM CTO Registry, a Latin American multicenter registry dedicated to prospective collection of these data. Inclusion criteria were procedures performed in Brazil, age 18 years or over, and presence of CTO with PCI attempt. CTO was defined as a 100% lesion in an epicardial coronary artery, known or estimated to have lasted at least 3 months. Results Data on 1196 CTO PCIs were included. Procedures were performed primarily for angina control (85%) and/or treatment of moderate/severe ischemia (24%). Technical success rate was 84%, being achieved with antegrade wire approaches in 81% of procedures, antegrade dissection and re-entry in 9%, and retrograde approaches in 10%. In-hospital adverse cardiovascular events occurred in 2.3% of cases, with a mortality rate of 0.75%. Conclusions CTOs can be treated effectively in Brazil by using PCI, with low complication rates. The scientific and technological development observed in this area in the past decade is reflected in the clinical practice of dedicated Brazilian centers.

Resumo Fundamento Tem sido observado um grande avanço nas técnicas e nos dispositivos para a realização de intervenções coronárias percutâneas (ICP) em oclusões totais coronarianas crônicas (OTC), mas existem poucos dados da prática do mundo real em países em desenvolvimento. Objetivos Relatar as características clínicas e angiográficas, os aspectos dos procedimentos e os resultados clínicos da ICP de OTC em centros dedicados a esse procedimento no Brasil. Métodos Os pacientes incluídos foram submetidos à ICP de OTC em centros participantes do LATAM CTO Registry, um registro multicêntrico latino-americano dedicado à coleta prospectiva desses dados. Os critérios de inclusão foram procedimentos realizados no Brasil, idade acima de 18 anos e presença de OTC com tentativa de ICP. A definição de OTC foi lesão de 100% em uma artéria coronária epicárdica, conhecida ou estimada como tendo pelo menos 3 meses de evolução. Resultados Foram incluídos dados de 1.196 ICPs de OTC. Os procedimentos foram realizados principalmente para controle da angina (85%) e/ou tratamento de uma grande área isquêmica (24%). A taxa de sucesso técnico foi de 84% e foi alcançada com técnicas de fios anterógrados em 81%, dissecção/reentrada anterógrada em 9% e retrógrada em 10% dos procedimentos. Os eventos cardiovasculares adversos intra-hospitalares ocorreram em 2,3% dos casos, sendo a mortalidade de 0,75%. Conclusões As OTC podem ser tratadas no Brasil por intervenção coronária percutânea de forma efetiva e com baixas taxas de complicações. O desenvolvimento científico e tecnológico observado nessa área na última década reflete-se na prática clínica de centros brasileiros dedicados a essa técnica.

Aim To evaluate the prevalence and factors associated with gummy smiles in adolescents aged between 15 and 18 years attending high school. Methods The cross-sectional and quantitative study was carried out during the Covid-19 pandemic, with 160 adolescents, from two public (A1) and two private (A2) schools chosen by lottery, divided into two groups: G1 (with gummy smile) and G2 (no gummy smile). A clinical examination was carried out on the adolescents, investigating the presence or absence of a gummy smile (GS), by analyzing the variables (interlabial distance at rest, upper incisor exposure at rest, smile arc, measurement from the subnasal to the upper lip philtrum, upper lip length, upper lip thickness, hypermobility and lower/middle third ratio). Means and dispersion were obtained, and the Chi-square association test was applied, to compare the results between A1 and A2 and between G1 and G2. Results The prevalence of GS was 33.8% (=54). It was found that no statistically significant associations were found (p > 0.05), regarding the type of school and gender with the presence of GS in adolescents. There was no statistically significant difference (χ2 = 1.82; p = 0.07) between the groups and the age of adolescents. There was a significant association between the studied variables and GS (p < 0.05). Conclusion The prevalence was high with a predominance of females. There were no statistically significant associations regarding the type of school and gender, but there was a significant association between gummy smile and lip dimensions.

RESUMO: Objetivou-se com este estudo investigar a correlação genética de 18 cepas de Staphylococcus aureus isoladas de infecções intramamárias em vacas primíparas e de locais extramamários em cinco propriedades leiteiras através das técnicas de PCR por sequências palindrômicas extragênicas repetitivas (rep-PCR), usando iniciadores RW3A, e de eletroforese em gel de campo pulsado (PFGE), usando a endonuclease SmaI. Os isolados também foram avaliados in vitro quanto à suscetibilidade aos antimicrobianos beta-lactâmicos (penicilina e oxacilina). A tipagem por rep-PCR foi altamente discriminatória (valor D = 0,9804) e um total de 15 padrões foram detectados. Os isolados de S. aureus foram agrupados em três grupos diferentes (A a C), com 80% de similaridade. A técnica de PFGE também foi altamente discriminatória (valor D = 0,9667) e um total de 13 padrões foi observado. A análise do dendrograma com um coeficiente de similaridade de 80% gerou dois grupos diferentes (A e B). Além disso, cepas clonais isoladas do leite foram identificadas na mesma propriedade pelos dois métodos de tipificação e, apesar da presença de cepas dominantes, nossos resultados sugerem uma alta diversidade genética dentre as cepas de S. aureus analisadas. Um total de 15, dos 18 (83%) isolados, eram resistentes à penicilina e um dos 18 (6%) à oxacilina. Assim, esses achados confirmam a ocorrência de uma alta diversidade genética de cepas de S. aureus nas propriedades e a presença de cepas clonalmente relacionadas apenas na mesma propriedade, enfatizando uma variedade de perfis genotípicos entre os isolados.

ABSTRACT: This research aimed to investigate the genotypic relatedness of 18 Staphylococcus aureus strains isolated from intramammary infections in primiparous cows and extramammary sites on five dairy herds by rep-PCR using RW3A primers, and by PFGE using the endonuclease SmaI. The isolates were also evaluated in vitro for the susceptibility against beta-lactam antimicrobials drugs (penicillin and oxacillin), considering that beta-lactams are frequently used for treating staphylococcal intrammamary infections. The rep-PCR typing was highly discriminatory (D value= 0.9804) and a total of 15 patterns were detected. The PFGE method was also highly discriminatory (D value= 0.9667) and a total of 13 patterns were observed. A total of 15 out of 18 (83%) isolates were resistant to penicillin and one out of 18 (6%) to oxacillin. In conclusion, these findings confirmed the occurrence of a high genetic diversity of S. aureus strains at the herds and the presence of clonally-related strains only at the same herd, emphasizing a variety of genotypic profiles among the isolates.

Resumen Este estudio evaluó la contribución de la nutrición con potasio (K) y la aplicación de las láminas de las aguas residuales al rendimiento agronómico del algodón colorido. Los tratamientos consistieron en cinco láminas de riego (50, 75, 100, 125 y 150% de la evapotranspiración del cultivo - ETC) y cinco dosis de K (0, 50, 100, 150 y 200% de la recomendación del cultivo). Fue también utilizado un control absoluto de riego con lámina 100% de la ETC y fertilizado con una recomendación de 100% N-P-K. Así como los tratamientos el control también tuvo cuatro repeticiones. La altura de la planta, el diámetro del tallo, el área de la hoja y la acumulación de materia seca del algodón en los brotes se evaluaron a los 130 días después de la emergencia (DAE), mientras que el peso del algodón semilla, se evaluó a 135 DAE. Los resultados indican que el uso de aguas residuales domésticas tratadas para compensación del 100% de ETC promueve un mayor aumento de peso y crecimiento del algodón colorido sin la necesidad de fertilización con K, lo que evidencia el potencial de las aguas residuales para el algodón colorido para una agricultura sostenible.

Abstract This study evaluated the contribution of potassium (K) nutrition and application of wastewater depths to the agronomic performance of colored cotton. Treatments consisted of five irrigation depths (50, 75, 100, 125 and 150% of crop evapotranspiration - ETC) and five K doses (0, 50, 100, 150 and 200% of the recommendation for the crop) and an absolute control irrigated with 100% ETC water depth and fertilized with 100% N-P-K recommendation. Each treatment and the control had four replicates. Plant height, stem diameter, leaf area and shoot dry matter accumulation of cotton were evaluated at 130 days after emergence (DAE), whereas seed cotton weight was evaluated at 135 DAE. Our findings indicate that the use of treated domestic sewage for 100% ETC replacement promotes greater gains of weight and growth in colored cotton without the need for K fertilization, evidencing the potential of wastewater for colored cotton for sustainable agriculture.

ABSTRACT The objective of this study was to evaluate the effect of light availability and salt stress on the growth and quality of hazel sterculia seedlings. The experiment was conducted with two light conditions – full sun (L1), and 50% shading (L2) – and five salinity levels in the irrigation water – 1.0 (S1), 2.2 (S2), 3.2 (S3), 4.2 (S4), and 5.1 (S5) dS m-1. The environment with 50% shading was the most suitable to produce hazel sterculia seedlings, even under high salinity (5.1 dS m-1). Increasing salinity negatively affects the growth and quality of hazel sterculia seedlings. Therefore, controlling sunlight availability and irrigation water saline conditions increases rooting potential and seedling survival in the field.

Materiais e Métodos: Estudo retrospectivo, analítico e transversal. Selecionamos exames de ressonância magnética do retropé de 90 pacientes que apresentavam atrofia muscular grau IV do abdutor do quinto dedo utilizando a classificação de Goutallier e Bernageau. Foram excluídos do estudo pacientes com níveis menores de degeneração muscular (abaixo do grau IV). Resultados: Houve predomínio do sexo feminino de 78,8% e alto índice de concordância da atrofia gordurosa do músculo abdutor do quinto dedo com fasciite plantar e varizes no tornozelo, respectivamente, encontrados em 21,2% e 16,8% dos pacientes. Conclusão: Atrofia gordurosa do músculo abdutor do quinto dedo está fortemente associada a alterações neuropáticas do primeiro ramo do plantar lateral. Nosso estudo mostrou associação significativa entre a fasciite plantar e varizes do tornozelo com atrofia grau IV do abdutor do quinto dedo.

Abstract Objective: To assess the prevalence of isolated findings of abnormalities leading to entrapment of the lateral plantar nerve and respective branches in patients complaining of chronic heel pain, whose magnetic resonance imaging exams have showed complete selective fatty atrophy of the abductor digiti quinti muscle. Materials and Methods: Retrospective, analytical, and cross-sectional study. The authors selected magnetic resonance imaging of hindfoot of 90 patients with grade IV abductor digiti quinti muscle atrophy according to Goutallier and Bernageau classification. Patients presenting with minor degrees of fatty muscle degeneration (below grade IV) and those who had been operated on for nerve decompression were excluded. Results: A female prevalence (78.8%) was observed, and a strong correlation was found between fatty muscle atrophy and plantar fasciitis in 21.2%, and ankle varices, in 16.8% of the patients. Conclusion: Fatty atrophy of the abductor digiti quinti muscle is strongly associated with neuropathic alterations of the first branch of the lateral plantar nerve. The present study showed a significant association between plantar fasciitis and ankle varices with grade IV atrophy of the abductor digiti quinti muscle.

ABSTRACT Vohwinkel syndrome, also known as hereditary mutilating keratoderma, is a rare palmoplantar keratoderma that manifests in childhood and becomes more evident in adolescence and adulthood. This preferential autosomal dominant disease affects more women and Caucasians. Its clinical features are diffuse palmoplantar keratoderma with the appearance of honeycomblike constricting rings in the fingers and toes known as pseudo-ainhum, and starfish-shaped keratotic plaques on the dorsal aspect of the hands and feet that can affect the elbows and knees. The present report describes a case report of a patient with Vohwinkel syndrome and surgical correction of the constrictive bands. adulthood Caucasians pseudoainhum, pseudoainhum pseudo ainhum, ainhum pseudo-ainhum starfishshaped starfish shaped knees bands

Rangelia vitalii é um protozoário que causa doença em cães, sendo a anemia o achado laboratorial mais frequente. No entanto, existem poucos estudos sobre as alterações bioquímicas em cães infectados com o protozoário. Assim, este estudo tem como objetivo investigar as alterações bioquímicas de cães experimentalmente infectados com R. vitalii na fase aguda da infecção. Para o estudo, foram utilizados 12 cães fêmeas (com idade entre 6 a 12 meses e peso entre 4 a 7 kg), divididos em dois grupos. O grupo A (n = 5) foi composto de animais saudáveis e o grupo B (n = 7) de animais infectados. Amostras de sangue foram coletadas nos dias zero, dez, vinte e trinta PI, utilizando tubos sem anticoagulante para obtenção de soro e análise dos parâmetros bioquímicos. Foi observado um aumento na alanino aminotransferase (ALT) no dia 20 PI (P < 0,05) e aumento na creatinoquinase (CK) e aspartato aminotransferase (AST) em todo o período experimental (P < 0,05). Não foram observadas alterações séricas na gama-glutamiltransferase, uréia e creatinina. Portanto, é possível concluir que a infecção experimental por R. vitalii causa alterações no perfil bioquímico, com aumento na ALT, CK e AST.

Rangelia vitalii is a protozoon that causes diseases in dogs, and anemia is the most common laboratory finding. However, few studies on the biochemical changes in dogs infected with this protozoon exist. Thus, this study aimed to investigate the biochemical changes in dogs experimentally infected with R. vitalii, during the acute phase of the infection. For this study, 12 female dogs (aged 6-12 months and weighing between 4 and 7 kg) were used, divided in two groups. Group A was composed of healthy dogs (n = 5); and group B consisted of infected animals (n = 7). Blood samples were collected on days 0, 10, 20 and 30 after infection, using tubes without anticoagulant to obtain serum and analyze the biochemical parameters. An increase in alanine aminotransferase (ALT) on day 20 (P < 0.05) was observed. Also, increased creatine kinase (CK) and aspartate aminotransferase (AST) levels were observed throughout the experimental period (P < 0.05). No changes in the serum gamma-glutamyltransferase, urea and creatinine levels were observed. Thus, is possible to conclude that experimental infection with R. vitalii in dogs causes changes to the biochemical profile, with increased ALT, AST and CK enzyme levels.

INTRODUÇÃO: A radioquimioterapia neoadjuvante promove redução do tamanho e do estadiamento dos tumores do reto antes da cirurgia, reduzindo o risco de acometimento de margem de ressecção circunferencial e da recorrência local. Para pacientes que se submeteram a neoadjuvância, a realização de uma segunda ressonância magnética (RNM) após a radioquimioterapia, para avaliação do resultado do tratamento, pode trazer dados relevantes para a programação cirúrgica e previsão do prognóstico, porém sua utilização ainda é controversa. OBJETIVO: Avaliar a capacidade da RNM prever o grau de regressão tumoral e o downstaging obtidos e a correlação entre o grau de regressão tumoral com o prognóstico dos pacientes. Métodos: Foram incluídos 13 pacientes até o momento; desses 69,23% eram do sexo masculino e a idade média foi de 52,3 anos. RESULTADOS: O anatomopatológico (AP) mostrou conformidade em relação ao estadiamento T e N estimado pela RNM pós-neoadjuvância de 30,76%; nos demais pacientes, houve tendência ao superestadiamento em 55,55%. No estadiamento T houve concordância de 53,84% e quanto ao status linfonodal, concordância 61,53%. A margem de ressecção circunferencial foi livre de neoplasia em 100%. A sobrevida foi de 92%, com 75% de sobrevida livre de doença num seguimento médio de 1-2 anos. CONCLUSÃO: Uma segunda ressonância após neoadjuvância pode avaliar se houve regressão tumoral, porém com baixa conformidade em relação ao anatomopatológico, com tendência ao superestadiamento. Mais estudos são necessários para corroborar essas impressões iniciais.

INTRODUCTION: Neoadjuvant chemoradiation promotes tumor size reduction and staging before the surgery, reducing the risk of involving the circumferential resection margin and local recurrence. For patients who have been submitted to the neoadjuvant therapy, the usefulness of a second nuclear magnetic resonance (MRI) after chemoradiation has not been clearly explained. Objective: Assess the degree of tumor regression and downstaging after chemoradiation using MRI, compared with the pathology, and its correlation with surgical outcomes and patient prognosis. METHODS: This study investigated 13 patients. Their mean age was 52.3 years and 69.23% were male. RESULTS: The agreement in T and N staging was 30.76%, between the second MRI and pathology, overestimated in 55.55% of the remaining. T staging agreement was 53.84% and N staging agreement, 61.53%. The circumferential resection margin was free of cancer in 100%. The survival rate was 92%, with 75% disease-free in a mean follow-up of 1-2 years. CONCLUSION: A second MRI after chemoradiation can evaluate the degree of tumor regression, but with low compliance in relation to pathology, with tendency to overstaging. More studies are required to confirm these initial observations.

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

O pseudoaneurisma de artéria mesentérica superior é uma doença rara, porém com alta taxa de ruptura e mortalidade. Sua etiologia geralmente é infecciosa e comumente o diagnóstico é feito por meio de achado nos exames de imagem. Historicamente, seu tratamento de eleição tem sido o reparo cirúrgico aberto; entretanto, é associado a inúmeras complicações e dificuldades técnicas. Relatamos um caso de pseudoaneurisma de artéria mesentérica superior em um paciente portador de abscesso hepático no qual, após resolução do processo infeccioso, foi empregado, com sucesso, um tratamento minimamente invasivo endovascular, com implante de micromolas e stent não-recoberto.

Pseudoaneurysm of the superior mesenteric artery is a rare disease, however it is associated to a high incidence of rupture and mortality. The etiology is usually infectious and the diagnosis is commonly made by means of occasional imaging. Historically, the treatment of choice has been open surgical repair; however it is associated to numerous complications and technical difficulties. We reported a case of a pseudoaneurysm of superior mesenteric artery in a patient with liver abscess who, after resolution of infection, underwent successfully a minimally invasive endovascular approach, with deployment of microcoils and bare stent.

JUSTIFICATIVA E OBJETIVOS: Diversas classes de fármacos inotrópicos, com efeitos hemodinâmicos diferentes, são utilizadas no tratamento do baixo débito cardíaco em pacientes com disfunção sistólica submetidos a procedimento cirúrgico cardíaco. O objetivo deste estudo foi comparar o efeito da dobutamina e da milrinona sobre a hemodinâmica e o transporte de oxigênio nessa população de pacientes. MÉTODO: Após aprovação do Comitê de Ética institucional e obtenção do consentimento escrito pós-informado, 20 pacientes submetidos à cirurgia cardíaca e com índice cardíaco < 2 L.min-1.m-2 pós-indução anestésica e instalação de cateter de artéria pulmonar foram distribuídos aleatoriamente para receber dobutamina 5 µg.kg-1.min-1 (n = 10) ou milrinona 0,5 µg.kg-1.min-1 (n = 10). Medidas hemodinâmicas foram obtidas pós-indução, 30 e 60 minutos após, e gasometrias arterial e venosa nos momentos basal e 60 minutos. Os dados foram comparados usando teste t de Student não pareado ou ANOVA de duas vias para medidas repetidas. RESULTADOS: A dobutamina e a milrinona promoveram aumentos significativos no índice cardíaco (56% e 47%) e no transporte de oxigênio (53% e 45%), redução nos índices de resistência vascular sistêmica (33% e 36%) e pulmonar (34% e 19%), respectivamente. Contudo, não foram observadas diferenças entre os fármacos. CONCLUSÕES: Ambos os fármacos inotrópicos foram igualmente efetivos em restaurar o fluxo tecidual sanguíneo e a oferta tecidual de oxigênio para valores adequados em pacientes com baixo débito cardíaco submetidos à cirurgia cardíaca.

BACKGROUND AND OBJECTIVES: Several classes of inotropic drugs with different hemodynamic effects are used in the treatment of low cardiac output in patients with diastolic dysfunction undergoing cardiac surgery. The objective of the present study was to compare the effects of dobutamine and milrinone on hemodynamic parameters and oxygen supply in this population of patients. METHODS: After approval by the Ethics Committee of the institution and signing of the informed consent, 20 patients undergoing cardiac surgery with cardiac index < 2 L.min-1.m2 after anesthetic induction and place ment of a pulmonary artery catheter were randomly divided to receive dobutamine 5 µg.kg-1. min-1 (n = 10), or milrinone 0.5 µg.kg-1.min-1 (n = 10). Hemodynamic parameters were measured after anesthetic induction and after 30 and 60 minutes, and arterial and venous blood gases were measured at baseline and 60 minutes. Non-paired Student t test or two-way ANOVA for repeated measurements was used to compare the data. RESULTS: Dobutamine and milrinone promoted significant increases in cardiac index (56% and 47%) and oxygen supply (53% and 45%), and reduction in systemic (33% and 36%) and pulmonary (34% and 19%) vascular resistance, respectively. However, statistically significant differences were not observed between both drugs. CONCLUSIONS: Both inotropic drugs were similarly effective in restoring tissue blood flow and oxygen supply to adequate levels in patients with low cardiac output undergoing cardiac surgery.
