Abstract: Pt Es En

A cardiomiopatia hipertrófica (CMH) é uma forma de doença do músculo cardíaco de causa genética, caracterizada pela hipertrofia das paredes ventriculares. O diagnóstico requer detecção por métodos de imagem (Ecocardiograma ou Ressonância Magnética Cardíaca) de qualquer segmento da parede do ventrículo esquerdo com espessura > 15 mm, sem outra causa provável. A análise genética permite identificar mutações de genes codificantes de diferentes estruturas do sarcômero responsáveis pelo desenvolvimento da CMH em cerca de 60% dos casos, permitindo o rastreio de familiares e aconselhamento genético, como parte importante do manejo dos pacientes e familiares. Vários conceitos sobre a CMH foram recentemente revistos, incluindo sua prevalência de 1 em 250 indivíduos, não sendo, portanto, uma doença rara, mas subdiagnosticada. A vasta maioria dos pacientes é assintomática. Naqueles sintomáticos, a obstrução do trato de saída do ventrículo esquerdo (OTSVE) é o principal distúrbio responsável pelos sintomas, devendo-se investigar a sua presença em todos os casos. Naqueles em que o ecocardiograma em repouso ou com Manobra de Valsalva não detecta gradiente intraventricular significativo (> 30 mmHg), devem ser submetidos à ecocardiografia com esforço físico para detecção da OTSVE.   Pacientes com sintomas limitantes e grave OTSVE, refratários ao uso de betabloqueadores e verapamil, devem receber terapias de redução septal ou uso de novas drogas inibidoras da miosina cardíaca. Por fim, os pacientes adequadamente identificados com risco aumentado de morta súbita podem receber medida profilática com implante de cardiodesfibrilador implantável (CDI).

La miocardiopatía hipertrófica (MCH) es una forma de enfermedad cardíaca de origen genético, caracterizada por el engrosamiento de las paredes ventriculares. El diagnóstico requiere la detección mediante métodos de imagen (Ecocardiograma o Resonancia Magnética Cardíaca) que muestren algún segmento de la pared ventricular izquierda con un grosor > 15 mm, sin otra causa probable. El análisis genético permite identificar mutaciones en genes que codifican diferentes estructuras del sarcómero responsables del desarrollo de la MCH en aproximadamente el 60% de los casos, lo que permite el tamizaje de familiares y el asesoramiento genético, como parte importante del manejo de pacientes y familiares. Varios conceptos sobre la MCH han sido revisados recientemente, incluida su prevalencia de 1 entre 250 individuos, por lo tanto, no es una enfermedad rara, sino subdiagnosticada. La gran mayoría de los pacientes son asintomáticos. En los casos sintomáticos, la obstrucción del tracto de salida ventricular izquierdo (TSVI) es el trastorno principal responsable de los síntomas, y su presencia debe investigarse en todos los casos. En aquellos en los que el ecocardiograma en reposo o la maniobra de Valsalva no detecta un gradiente intraventricular significativo (> 30 mmHg), deben someterse a ecocardiografía de esfuerzo para detectar la obstrucción del TSVI. Los pacientes con síntomas limitantes y obstrucción grave del TSVI, refractarios al uso de betabloqueantes y verapamilo, deben recibir terapias de reducción septal o usar nuevos medicamentos inhibidores de la miosina cardíaca. Finalmente, los pacientes adecuadamente identificados con un riesgo aumentado de muerte súbita pueden recibir medidas profilácticas con el implante de un cardioversor-desfibrilador implantable (CDI).

Hypertrophic cardiomyopathy (HCM) is a form of genetically caused heart muscle disease, characterized by the thickening of the ventricular walls. Diagnosis requires detection through imaging methods (Echocardiogram or Cardiac Magnetic Resonance) showing any segment of the left ventricular wall with a thickness > 15 mm, without any other probable cause. Genetic analysis allows the identification of mutations in genes encoding different structures of the sarcomere responsible for the development of HCM in about 60% of cases, enabling screening of family members and genetic counseling, as an important part of patient and family management. Several concepts about HCM have recently been reviewed, including its prevalence of 1 in 250 individuals, hence not a rare but rather underdiagnosed disease. The vast majority of patients are asymptomatic. In symptomatic cases, obstruction of the left ventricular outflow tract (LVOT) is the primary disorder responsible for symptoms, and its presence should be investigated in all cases. In those where resting echocardiogram or Valsalva maneuver does not detect significant intraventricular gradient (> 30 mmHg), they should undergo stress echocardiography to detect LVOT obstruction. Patients with limiting symptoms and severe LVOT obstruction, refractory to beta-blockers and verapamil, should receive septal reduction therapies or use new drugs inhibiting cardiac myosin. Finally, appropriately identified patients at increased risk of sudden death may receive prophylactic measure with implantable cardioverter-defibrillator (ICD) implantation.

Abstract Inflammatory bowel disease (IBD) is a problem that directly affects the quality of life of patients suffering from this condition. Monitoring the serum level of infliximab (IFX) (TDM) is an important tool for guiding therapeutic decisions in IBD patients. The purpose of this study was to determine the significance of quantitatively measuring the serum level of IFX (TDM) and antibody to IFX (ATI). Methods and materials: Prospective observational study involving 40 IBD patients on IFX therapy, including 14 Proactive (week 06 of the induction phase) and 26 Reactive (maintenance phase). Immediately prior to the infusion, blood samples were drawn and measured using a Bulhlmann rapid test instrument. Serum concentrations of IFX were categorized as supratherapeutic (>7.0 micrograms/ml), therapeutic (between 3.0 and 7.0 micrograms/ml), and subtherapeutic (3.0 micrograms/ml). When the serum concentration of IFX was 3 mcg/ml (subtherapeutic), the ATI was measured. 25 patients with CD and 15 patients with UC were evaluated. Only three of the twenty patients with subtherapeutic serum levels had a positive ATI, and both were reactive; two had CD and one had UC. There was a statistically significant difference between reactive and proactive patients with respect to levels of CRP (p = 0.042), with proactive DNS patients suffering greater alterations in CRP and albumin.

Abstract: En Es Pt

This article seeks to compose a historical overview of the pedagogical and institutional organization of what we are calling unconventional educational communities, that is, institutions that have merged school practice with the housing of educators and students, where children and adults live and cohabit in the space where they learn and educate, They form boarding schools, colonies, orphanages, school-residences that are organized by their members collectively managing the institution and proposing important transformations in the educational processes with considerable degrees of autonomy and pedagogical creativity. We start from the institutions coordinated by Johann Heinrich Pestalozzi, Friedrich Froebel and Liev Tolstoi, then we discuss the anarchist educational communities coordinated by Paul Robin and Sébatien Faure, the democratic orphanages coordinated by Janusz Korczak, the educational socialist colonies of Anton Semionovich Makarenko, the self-managed boarding school of Homer Lane, and the CIEPs in the state of Rio de Janeiro. We also mention some more recent and still existing cases, such as the Summerhill School, the Krishnamurti schools and the Escola SESC de Ensino Médio. We used as a method the analysis of historiographic texts and cited some reports for more contemporary cases. We were able to conclude that the format of boarding-schools and orphanages with the inclusion of school practices were paradigmatic institutional models between the 18th century and the beginning of the 20th century, and that nowadays the few cases in these formats are maintained by institutions run by religious organizations. However, we bring in our text some examples of rupture to the conventional pedagogical paradigm that occurred in some contemporary educational communities.

Este artículo pretende componer una panorámica histórica de la organización pedagógica e institucional de lo que estamos denominando comunidades educativas no convencionales, es decir, instituciones que han fusionado la práctica escolar con la vivienda de educadores y alumnos, donde niños y adultos viven y cohabitan en el espacio donde aprenden y se educan, formando internados, colonias, orfanatos, escuelas-residencia que se organizan con sus miembros gestionando colectivamente la institución y proponiendo importantes transformaciones en los procesos educativos con grados considerables de autonomía y creatividad pedagógica. Partimos de las instituciones coordinadas por Johann Heinrich Pestalozzi, Friedrich Froebel y Liev Tolstoi, para pasar después a las comunidades educativas anarquistas coordinadas por Paul Robin y Sébatien Faure, los orfanatos democráticos coordinados por Janusz Korczak, las colonias educativas socialistas de Anton Semionovich Makarenko, el internado autogestionado de Homer Lane y los CIEP del estado de Río de Janeiro. También mencionamos algunos casos más recientes y aún vigentes, como la Summerhill School, las escuelas Krishnamurti y la Escuela SESC de Ensino Médio. Utilizamos como método el análisis de textos historiográficos y citamos algunos informes para los casos más contemporáneos. Podríamos concluir que el formato de internados y orfanatos con inclusión de prácticas escolares fueron modelos institucionales paradigmáticos entre el siglo XVIII y principios del XX, y que en la actualidad los pocos casos en estos formatos son mantenidos por instituciones para organizaciones religiosas. Sin embargo, aportamos en nuestro texto algunos ejemplos de ruptura con el paradigma pedagógico convencional ocurridos en algunas comunidades educativas contemporáneas.

Este artigo busca compor um panorama histórico da organização pedagógica e institucional do que estamos denominando de “comunidades educacionais não-convencionais”, ou seja, instituições que mesclaram a prática escolar com a moradia dos educadores e educandos, onde crianças e adultos residem e coabitam no espaço em que aprendem e se educam, formando “internatos”, “colônias”, “orfanatos”, “escolas-residência” que se organizam com seus membros gestando coletivamente a instituição e propondo importantes transformações nos processos educacionais com consideráveis graus de autonomia e criatividade pedagógica.nbsp; Partimos das instituições coordenadas por Johann Heinrich Pestalozzi, Friedrich Froebel e Liev Tolstoi, depois discutimos as comunidades educacionais anarquistas coordenadas por Paul Robin e Sébatien Faure, os orfanatos democráticos coordenados por Janusz Korczak, as colônias socialistas educacionais de Anton Semionovich Makarenko, o internato autogestionado de Homer Lane e os CIEPs no estado do Rio de Janeiro. Citamos também alguns casos mais recentes e ainda existentes, como a Summerhill School, as “escolas Krishnamurti” e a Escola SESC de Ensino Médio. Utilizamos como método a análise de textos historiográficos e citamos algumas reportagens para os casos mais contemporâneos. Pudemos concluir que o formato de “escolas-internatos” e orfanatos com inclusão de práticas escolares foram modelos institucionais paradigmáticos entre o século XVIII e início do século XX, e que na atualidade os poucos casos nestes formatos são mantidos por instituições por organizações religiosas. No entanto, trouxemos em nosso texto alguns exemplos de rompimento ao paradigma pedagógico convencional ocorrido em algumas comunidades educacionais contemporâneas.

ABSTRACT Evaluating the effects of N and K supply on grapevines ( Vitis vinifera L.) and the techniques for nutritional diagnosis is of great importance for fertigation management of this crop. This study evaluated the effects of N and K fertigation on the soluble concentrations of NO 3 – and K + in the petiole sap and on the leaf chlorophyll index in drip irrigated ‘Syrah’ grapevine (from 17 June 2013 to 25 Nov 2014). The treatments consisted of five levels of N (0, 15, 30, 60 and 120 kg ha –1 ) and K 2 O (0, 15, 30, 60 and 120 kg ha –1 ), combined in an incomplete 5 2 factorial scheme in 13 combinations and arranged in randomized blocks with four replications. We determined NO 3 – and K + concentrations in petiole sap, leaf chlorophyll index, grapevine cluster mass and number per plant, mean grapevine cluster mass, and phenolic composition. High NO 3 – concentrations contributed positively to grapevine yield; however, increased K+ concentrations caused a negative response of sap. For 120 kg N ha –1 rate, NO 3 – in the sap and chlorophyll index showed higher values at the flowering stage, while high values for K + were observed during the grape-ripening stage.

ABSTRACT BACKGROUND: Weight regain in the postoperative period after bariatric surgery is directly related to the relapse of preoperative comorbidities and a negative impact on the patients’ biochemical profile. AIMS: To assess the metabolic impact of weight regain on preoperative comorbidities and on patients’ biochemical profiles, in order to show the impact of the complications on the metabolic outcomes of bariatric surgery. METHODS: A retrospective study was carried out with 75 women in the late postoperative period of bariatric surgery who presented pathological weight regain (≥20% of the maximum weight loss). Data of interest consisted of glycemic, lipid, and inflammatory profile measurements at three different moments of evaluation: preoperative period, at the weight nadir (minimum weight), and after weight regain. A multivariate analysis was performed. RESULTS: The mean age was 46.39±12.09 years. Preoperative body mass index was 40.10±4.11 kg/m2. There was an overall increase of 3.36 points in the mean body mass index between the nadir and after regain: from 26.30±3.9 kg/m2 to 29.66±4.66 kg/m2. The mean time to reach the nadir was 18±7.6 months, with an average percentage of excess weight loss of 91.08±11.8%. The median time for pathological weight regain was 48 months, and the mean regain amongst the sample was 8.85±5.65 kg. There was a significant correlation between pathological weight regain and levels of insulin (r=0.351; p<0.011), C-peptide (r=0.303; p<0.011), C-reactive protein (r=0.402; p<0.001), and vitamin D (r=-0.435; p<0.001), the last two being the most influenced by the percentage of weight regained. CONCLUSIONS: The pathological weight regain in the postoperative period of bariatric surgery results in losses in the patients’ metabolic and inflammatory profiles. However, the biochemical benefits are sustained up to the preoperative levels of the parameters analyzed.

RESUMO RACIONAL: Reganho de peso no pós-operatório de cirurgia bariátrica está diretamente relacionado à recidiva das comorbidades pré-operatórias e a um impacto negativo no perfil bioquímico desses pacientes. OBJETIVOS: avaliar o impacto metabólico do reganho de peso nas comorbidades pré-operatórias e no perfil bioquímico desses pacientes, a fim de mostrar o impacto das complicações nos desfechos metabólicos finais da cirurgia bariátrica. MÉTODOS: Estudo retrospectivo que analisou 75 mulheres no pós-operatório tardio de cirurgia bariátrica que apresentaram reganho patológico de peso (=20% do máximo de peso perdido). Foram coletados dados referentes às medidas dos perfis glicêmico, lipídico e inflamatório em três momentos distintos de avaliação: no pré-operatório, no nadir de peso (menor peso) e após o reganho ponderal. Foi realizada uma análise multivariada. RESULTADOS: A idade média foi 46.39±12.09 anos. IMC médio pré-operatório foi 40.10±4.11 kg/m2. Houve um aumento de 3,36 pontos no IMC médio entre o nadir e após reganho: de 26.30±3.9 Kg/m2 para 29.66±4.66 Kg/m2. O tempo médio para atingir o nadir foi de 18±7.6 meses, com uma %PEP de 91.08±11.8%. O tempo médio para o reganho patológico foi de 48 meses, e a média de reganho foi 8.85±5.65 kg. Houve correlação significativa entre o reganho patológico e os níveis de insulina (r=0.351; p<0.011), peptídeo C (r=0.303; p<0.011), proteína C reativa (r=0.402; p<0.001) e vitamina D (r=-0.435; p<0.001), sendo os dois últimos os mais influenciados pela porcentagem de reganho de peso. CONCLUSÕES: O reganho de peso patológico no pós-operatório de cirurgia bariátrica resulta em prejuízos ao perfil metabólico e inflamatório dos pacientes. No entanto, os benefícios bioquímicos perduram em relação aos níveis pré-operatórios dos parâmetros analisados

ABSTRACT. Two experiments were carried out to evaluate the effects of protease addition to the diet of broilers at a higher level (1× or 2×) than the nutritional value proposed for the enzyme. The first experiment, 1280 day-old chicks (Cobb500®) were randomly allocated (randomized block design, 2×2+1 factorial arrangement), five treatments, eight replicates containing 32 birds/replicate. Treatments consisted: control diet without protease (CD); CD + 1× nutritional value of the enzyme (CDM1); CD + 2× nutritional value of the enzyme (CDM2); CDM1 + protease; and CDM2 + protease. The experimental period was 42 days. The mean weight (AFW), feed intake (FI), weight gain (WG), feed conversion, and carcass yield were evaluated. Significant differences were observed for AFW, WG, FI, abdominal fat yield, and feet percentage in the carcass. In the second experiment, 120 Cobb500® chicks at 14 days of age were allotted in a completely randomized design, 2×2+1 factorial arrangement, five treatments, six replicates with four birds/replicate. The treatments were consistent with the first experiment. Significant improvements in the nitrogen balance were observed for the broilers that received protease. The use of the enzyme tested is recommended with the recommended nutritional matrix, improving the zootechnical indices of broilers.

Abstract The oil from the fruit of peach palm or Pupunha (Bactris gasipaes) is an example of a material with low-cost and good antioxidant capacity. However, Conventional methods for measuring oil content are time-consuming, labor-intensive and use toxic chemicals. In this sense, the aim of this study was evaluated fast and non-destructive spectroscopy methods, such as Near Infrared (NIR) and Time-Domain Nuclear Magnetic Resonance (TD-NMR) (CPMG and ROSE pulse sequences), to quantify the oil content in pupunha flours collected in the amazon forest. For this, 93 samples were used and the results showed three distinct levels of oil in the samples: high, medium and low oil content. Furthermore, the determination coefficient (R2) reached values of 0.92, 0.92 and 0.70 for NIR, TD-NMR (ROSE) and TD-NMR (CPMG), respectively. Therefore, the NIR and TD-NMR (ROSE) methods demonstrate a higher prediction efficiency, with the NIR achieving 100% classification of the samples.

Abstract In this study, succinoglycan was produced from whey and its rheological and structural characteristics were elucidated. Eight culture media were prepared with different ions for bioconversion of whey into succinoglycan. The formulation composed of deproteinized whey, monobasic potassium phosphate and magnesium sulfate allowed the production of 13.7 ± 0.43 g/L of succinoglycan. The apparent molar mass of succinoglycan was estimated to be 9.033 × 105 g/mol and the polydispersity index was 1.044, representing the homogeneity of the sample. Monosaccharide composition of glucose and galactose for the succinoglycan produced was 6.6:1.0. The 1H RMN analysis revealed the non-saccharide substituent content of 1.2%, 3.0% and 8.1% for acetyl, succinate and pyruvate, respectively. The rheological results showed that the apparent viscosity of the succinoglycan solutions was directly proportional to the concentration, and the solution showed pseudoplastic behavior. Dynamic frequency sweep tests identified that a concentration of 2.0% of succinoglycan is required for formation of the gel system. Temperature influenced the viscoelastic behavior of succinoglycan and revealed the melting point and reversibility of the gel. Whey was shown to be a promising carbon source for the production of succinoglycan with thickening potential and viscosity modifier.

Abstract: En | Text: En | PDF: En

The use of alternative raw materials is essential for establishing a circular economy in the mineral and ironmaking sectors. Therefore, this study investigates the potential of lime sludge as fluxing material during pelletization and proposes an alternative route for the usage of waste. The pellets were manufactured with different binary basicity values (CaO/SiO2) (0.15-0.45) and bentonite (0.5-0.7 wt%) and fixed carbon (0.5-1.1 wt%) contents. The results demonstrated that lime sludge has significant potential for application in pelletization. Pellet quality was evaluated using drop number, mechanical strength, tumble index, porosity, and kinetic analyses. Pellets with the optimal composition using lime sludge withstood 3.6 drops/pellet, a tumble test of 1.57 wt.%, and a mechanical strength test of 214.83 kgf/pellet and exhibited a porosity of 31.28%. Lime sludge did not influence the reducibility of the iron-ore pellets. In the temperature range of 800-900 °C, the reaction was controlled by diffusion, with Ea between 179.89 and 233.10 kJ/mol.

ABSTRACT Purpose: to determine the risks and benefits of bariatric surgery in patients with super obesity (SO) in comparison with obesity grades II and III. Methods: retrospective cohort that included a study group of 178 patients with SO and a control group of 181 patients with BMI 35-49.9Kg/m2. The groups were formed in a 1:1 nearest neighbor matching. The main variables were pre- and postoperative BMI and comorbidities, occurrence of severe postoperative complications, bowel obstruction, marginal ulcer, fistulae and 30-day death, besides the necessity of emergency room (ER) admission and abdominal computed tomography (CT) scans in the postoperative period due to acute abdomen. Results: the study group comprised 74.0% of women while the control group had 56.7%. The mean follow-up time was similar between both groups (5.48 x 6.09 years, p=0.216). There was no statistically significant difference on the prevalence of hypertension and T2D between the groups according to the surgical technique. All deaths occurred in the Study group (BMI = 50kg/m2) who underwent RYGB. There was no difference between the groups regarding the occurrence of severe complications. Data on ER admissions and the need for abdominal CT to investigate postoperative abdominal pain did not show statistically significant difference between the groups. Conclusion: despite the high risk related to bariatric surgery in patients with SO, the benefits related to the remission of comorbidities are significant; although being lower than those found in patients with milder grades of obesity.

RESUMO Objetivo: determinar os riscos e benefícios da cirurgia bariátrica em pacientes com superobesidade em comparação com obesidade graus II e III. Métodos: coorte retrospectiva que incluiu um grupo Estudo com 178 pacientes portadores de superobesidade e um controle com 181 pacientes com IMC 35-49.9Kg/m2. Os grupos foram formados numa razão 1:1 com pareamento “vizinho próximo”. As principais variáveis foram comorbidades e IMC pré e pós-operatório, ocorrência de complicações pós-operatórias severas, obstrução intestinal, úlcera marginal, fístula e morte em 30 dias, além da necessidade de idas à emergência e realização de tomografia computadorizada (CT) para investigação de abdome agudo. Resultados: o grupo Estudo foi composto por 74.0% de mulheres, enquanto o Controle teve apenas 56.7%. O tempo médio de seguimento foi similar em ambos os grupos (5.48 x 6.09 anos, p=0.216). Não houve diferença estatisticamente significativa em relação à prevalência de diabetes entre os grupos nem entre a técnica cirúrgica empregada. Todos os óbitos ocorreram no grupo Estudo (IMC = 50kg/m2), com apenas pacientes submetidos ao BGYR. Não houve diferença significativa entre os grupos em relação à ocorrência de complicações pós-operatórias. Ao avaliar idas à emergência e necessidade de TC para investigar dor abdominal, também não foi observada difrença significativa entre os grupos. Conclusão: apesar do alto risco cirúrgico implicado em pacientes portadores de superobesidade, os benefícios relacionados à remissão de comorbidades ainda são significativos; contudo os resultados parecem ser inferiores aos pacientes com graus mais leves de obesidade.

Abstract Background Spontaneous intracranial hypotension (SIH) is a secondary cause of headache and an underdiagnosed disease. The clinical presentation can be highly variable. It typically presents with isolated classic orthostatic headache complaints, but patients can develop significant complications such as cerebral venous thrombosis (CVT). Objective To report 3 cases of SIH diagnosis admitted and treated in a tertiary-level neurology ward. Methods Review of the medical files of three patients and description of clinical and surgical outcomes. Results Three female patients with SIH with a mean age of 25.6 ± 10.0 years old. The patients had orthostatic headache, and one of them presented with somnolence and diplopia because of a CVT. Brain magnetic resonance imaging (MRI) ranges from normal findings to classic findings of SIH as pachymeningeal enhancement and downward displacement of the cerebellar tonsils. Spine MRI showed abnormal epidural fluid collections in all cases, and computed tomography (CT) myelography could determine an identifiable cerebrospinal fluid (CSF) leak in only one patient. One patient received a conservative approach, and the other two were submitted to open surgery with lamino-plasty. Both of them had uneventful recovery and remission in surgery follow-up. Conclusion The diagnosis and management of SIH are still a challenge in neurology practice. We highlight in the present study severe cases of incapacitating SIH, complication with CVT, and good outcomes with neurosurgical treatment.

Resumo Antecedentes Hipotensão intracraniana espontânea (HIE) é uma causa secundária de cefaleia e uma doença subdiagnosticada. A apresentação clínica pode ser muito variável. Tipicamente, se apresenta com queixas isoladas de cefaleia ortostática clássica, porém pode evoluir com complicações significativas como trombose venosa cerebral (TVC). Objetivo Relatar 3 casos de diagnóstico de hipotensão intracraniana espontânea manejados em uma enfermaria de neurologia de nível terciário. Métodos Revisão dos prontuários de três pacientes e descrição dos resultados clínicos e cirúrgicos. Resultados Três pacientes do sexo feminino com média de idade de 25.6 ± 10.0 anos. As pacientes apresentavam cefaleia ortostática e uma delas apresentou sonolência e diplopia devido a TVC. A ressonância magnética (RM) do encéfalo varia de achados normais até achados clássicos de HIE como realce paquimeníngeo e deslocamento inferior das tonsilas cerebelares. A RM da coluna mostrou coleções anormais de líquido epidural em todos os casos e a mielografia por tomografia computadorizada (TC) foi capaz de determinar fístula liquórica identificável em apenas uma paciente. Uma paciente recebeu abordagem conservadora e as outras duas foram submetidas a cirurgia aberta com laminoplastia. Ambas tiveram recuperação e remissão sem intercorrências no seguimento cirúrgico. Conclusão O diagnóstico e manejo da hipotensão intracraniana ainda são desafios na prática neurológica. Destacamos no presente estudo casos graves, complicação com TVC e bons resultados com tratamento neurocirúrgico.

Abstract To evaluate the feasibility of using a milled polyetheretherketone (PEEK) post and core in endodontically treated teeth with or without a ferrule. Sixty bovine tooth roots were endodontically treated followed by cementation of intraradicular retainers (IR), according to each experimental group: a) non-ferrule glass fiber post (f0FP); b) 2-mm-ferrule glass fiber post (f2FP); c) non-ferrule resized glass fiber post (f0PR); d) 2-mm-ferrule resized glass fiber post (f2PR); e) non-ferrule PEEK post and core (f0PPC); and f) 2-mm-ferrule PEEK post and core (f2PPC). Metal crowns were made and cemented. A periodontal ligament was simulated using polyether. A force was applied to the palatine portion of each sample at 45°, until fracture. Fracture resistance data were submitted to two-way ANOVA and Tukey’s test (α = 0.05). Three-dimensional digital models were developed to calculate the tensions formed in the root using finite element analysis. Models of glass fiber posts and PEEK posts and cores were evaluated with or without a ferrule. The results were analyzed by the Mohr-Coulomb criterion. The type of IR was not influenced by fracture strength (p = 0.243). There were significant statistical differences among the remaining factors. Ferrule groups had greater fracture resistance, and the failure mode of teeth with a ferrule was more catastrophic than the non-ferrule group. A ferrule increases fracture resistance and influences failure mode; the PEEK post and core did not modify the biomechanics of endodontically treated teeth, and resembled the glass fiber post results. The crack initiation point differed between the ferrule and non-ferrule groups.
