Resumo: ABSTRACT Background: The etiology of stroke, a severe complication of sickle cell anemia, involves inflammatory processes. However, the pathogenetic mechanisms are unknown. The aim of this study was to evaluate the influence of interleukin-10 polymorphisms and haplotypes on the risk of acute cerebral ischemia and high-risk transcranial Doppler in 395 children with sickle cell anemia from the state of Minas Gerais, Brazil. Methods: Interleukin-10 haplotypes were determined by polymerase chain reaction-restriction fragment length polymorphism and sequencing. The outcomes studied were acute cerebral ischemia and high-risk transcranial Doppler. Clinical data were retrieved from the children's records. Results: There was no statistically significant difference in the frequencies of polymorphisms and haplotypes between children with and without acute cerebral ischemia or children with or without high-risk transcranial Doppler. These data are consistent with a previous report that showed an absence of association between interleukin-10 plasma levels and high-risk transcranial Doppler velocity in children with sickle cell anemia. Conclusion: Interleukin-10 haplotypes were not associated with the risk of acute cerebral ischemia or high-risk transcranial Doppler velocity in children with sickle cell anemia from the state of Minas Gerais, Brazil.

Título: Brazilian Guidelines for transcranial doppler in children and adolescents with sickle cell disease
Fonte: Rev. bras. hematol. hemoter;33(1):43-48, Feb. 2011. ilus, tab.
Idioma: en.
Resumo: BACKGROUND: Sickle cell disease is the most common monogenic hereditary disease in Brazil. Although strokes are one of the main causes of morbidity and mortality in these patients, the use of transcranial Doppler to identify children at risk is not universally used. OBJECTIVE: To develop Brazilian guidelines for the use of transcranial Doppler in sickle cell disease children and adolescents, so that related health policies can be expanded, and thus contribute to reduce morbidity and mortality. METHODS: The guidelines were formulated in a consensus meeting of experts in transcranial Doppler and sickle cell disease. The issues discussed were previously formulated and scientific articles in databases (MEDLINE, SciELO and Cochrane) were carefully analyzed. The consensus for each question was obtained by a vote of experts on the specific theme. RESULTS: Recommendations were made, including indications for the use of transcranial Doppler according to the sickle cell disease genotype and patients age; the necessary conditions to perform the exam and its periodicity depending on exam results; the criteria for the indication of blood transfusions and iron chelation therapy; the indication of hydroxyurea; and the therapeutic approach in cases of conditional transcranial Doppler. CONCLUSION: The Brazilian guidelines on the use of transcranial doppler in sickle cell disease patients may reduce the risk of strokes, and thus reduce the morbidity and mortality and improve the quality of life of sickle cell disease patients.

Título: Abnormal transcranial Döppler ultrasonography in children with sickle cell disease
Fonte: Rev. bras. hematol. hemoter;34(4):307-310, 2012. tab.
Idioma: en.
Resumo: BACKGROUND: Stroke is a potentially fatal complication of sickle cell disease in children between 2-16 years and transcranial Döppler has been recommended as a screening method in these cases. OBJECTIVE: The main goal of this study was to correlate transcranial Döppler results to complications related to stroke in sickle cell disease and baseline characteristics of the population. METHODS: This was an observational study of children and adolescents with ages between 2-16 years with sickle cell disease who were followed in three centers. RESULTS: From January 2008 to July 2009, 902 patients were enrolled in this study. The median age was 6.5 years (range: 1.8-15.8), 52.3% were male, 74.4% had hemoglobin SS; 221 (28.6%) had at least one complication associated with sickle cell disease. A total of 773 patients performed transcranial Döppler; in 91.2% this was a method of screening. Conditional or abnormal transcranial Döppler results were more common in patients with sickle cell disease complications versus those without complications (ODDS ratio = 3.18; 95% Confidence interval = 1.92-5.27). There was a significant difference in the frequency of conditional or abnormal transcranial Döppler results in patients with abnormal laboratory results compared to those without abnormalities (OR=4.03); 95% confidence interval = 2.30-7.06. CONCLUSIONS: Conditional or abnormal transcranial Döppler results were significantly more frequent in patients with complications of sickle cell disease confirming the increased risk of stroke in this subgroup of patients. This observation reinforces the recommendation of transcranial Döppler as a screening test for all patients with sickle cell disease with ages between 2 and 16 years.

Título: Ultrasonografía craneal neonatal / Neonatal cranial ultrasonography
Fonte: MedUNAB;15(3):167-174, 2012.
Idioma: es.
Resumo: La neuroecografía está posicionada en la práctica clínica, de acuerdo a la literatura consultada, como un procedimiento con una especificidad y efectividad que permite dar un reporte diagnóstico con seguridad. Esta técnica tiene como ventajas la exploración en tiempo real, el carácter atóxico e inocuo del procedimiento y el corto tiempo en el que se realiza, según la experticia del realizador. Como herramienta diagnóstica en recién nacidos pretérminos una de las principales indicaciones para la solicitud del procedimiento es poder hacer la identificación de las alteraciones visibles en la anatomía macroscópica, teniendo en cuenta las ventajas proporcionadas por la ventana acústica utilizada en el estudio sonográfico, las cuales dependen principalmente de la proximidad del transductor a la neuroanatomía que se desea explorar. [Ustáriz CG, Redondo LC, Avendaño LC, Noguera EC. Ultrasonografía craneal neonatal, revisión de tema. MedUNAB 2012; 15(3): 167-174].

According to the literature, the neurosonography technique is positioned in clinical practice as a procedure with a specificity and effectiveness which allows a safe diagnostic report. This technique has the advantages of real-time scanning, the non-toxic and harmless character of the procedure, and the short time in which is performed according to the expertise of the physician. Used as a diagnostic tool in preterm newborns, one of its most significant applications is the identification of the visible changes in macroscopic anatomy, taking into account the advantages provided by the acoustic window used in the sonographic study, which in turn depends mainly on the proximity of the transducer to the neuroanatomy to be scanned.

Resumo: Objetivos: Establecer la asociación de vasoespasmo cerebral detectado por Doppler transcraneal y la condición clínica, de acuerdo con la escala de la Federación Mundial de Sociedades de Neurocirugía, y con otros factores de riesgo en pacientes con hemorragia subaracnoidea espontánea. Materiales y métodos: Estudio observacional retrospectivo de casos y controles, con 141 pacientes diagnosticados con hemorragia subaracnoidea espontánea a quienes se les realizó Doppler transcraneal de seguimiento entre el 8 de marzo de 2011 y el 15 de marzo de 2015. Del total de pacientes se escogieron 47 con vasoespasmo detectado por Doppler transcraneal y 2 controles, sin vasoespasmo, por cada caso (94 pacientes). En las historias clínicas y las imágenes de los pacientes se estableció la asociación entre la detección de vasoespasmo por Doppler transcraneal con la condición clínica neurológica en el momento del examen, y otros factores de riesgo. Para el análisis de las variables cualitativas se utilizaron frecuencias absolutas y relativas. Para variables cuantitativas se utilizó la prueba de Shapiro Wilk. Los datos con distribución normal se presentan con medias y desviaciones estándar y aquellos sin distribución normal con medianas y rangos intercuartiles. Se evaluó la homogeneidad entre los dos grupos a través de la prueba de Chi cuadrado y el test de homogeneidad de varianzas (Levene) de acuerdo con el tipo de variable. Se consideró estadísticamente significativa una p ≤ 0,05. Resultados: El análisis bivariado no demostró resultados estadísticamente significativos en la relación entre la condición clínica neurológica y el vasoespasmo, pero sí encontró que pacientes menores de 50 años de edad presentaron más vasoespasmo (OR de 3,55 [95 % IC; 1,52-7,39]), y p: 0,003 que los de mayor edad. Conclusiones: Los pacientes menores de 50 años de edad tienen más riesgo de desarrollar vasoespasmo y no existe asociación entre la condición clínica y los resultados del Doppler transcraneal.

Objectives: Establish the association between cerebral vasospasm, detected by transcranial doppler, with the clinical condition according to the scale of the World Federation of Neurosurgical Societies (WFNS) and other risk factors in patients with spontaneous subarachnoid hemorrhage. Materials and methods: This is an observational retrospective case-control study, including 141 patients with a diagnosis of spontaneous subarachnoid hemorrhage who underwent transcranial doppler monitoring in the radiology department of the University Hospital San Vicente Foundation (HUSVF) from 8 March 2011 to 15 March 2015. Of the total number of patients with subarachnoid hemorrhage, 47 cases with vasospasm, detected by transcranial Doppler, and two controls without vasospasm (94 patients) were consecutively chosen. Subsequently, we review the medical records and images stored in the hospital´s radiology department and established the association between vasospasm detection by trasncranial Doppler with clinical neurological status at the time of the study and other risk factors. For the analysis of the qualitative variables, absolute and relative frequencies were used. Quantitative variables were tested for normal distribution with a Shapiro Wilk test. Data with normal distribution were presented with means and standard deviations and those without normal distribution with medians and interquartile ranges. Homogeneity between the two groups were evaluated by Chi-square test and test for homogeneity of variances, Levene's test, according to the type of variable (qualitative and quantitative respectively). Results were considered statistically significant if p ≤ 0.05. Results: Data from 141 patients (47 cases and 94 controls) were analyzed. The bivariate analysis didn´t show statistically significant results in the relationship between vasospasm and clinical neurological condition but found that patients younger than 50 years had more vasospasm. In the adjusted model for patients with this age, the OR was 3.55 (95 % CI, 1.52-7.39) and p: 0.003 when compared with older patients. Conclusions: This study found that patients under 50 have a higher risk of developing vasospasm compared with older patients and that there is no association between clinical condition and the results of transcranial Doppler.

Resumo: Paciente femenina de 46 años de edad, con antecedentes de hipertensión arterial y fumadora habitual. Desde hace 2 años presenta episodios aislados y breves de vértigos, inestabilidad postural, sensación de desfallecimiento sin alteraciones de la conciencia, después de realizar ejercicios del brazo izquierdo. El examen neurológico muestra asimetría de pulsos carotídeos y radiales. El doppler extracraneal reveló alteraciones ateroscleróticas en ambos ejes carotídeos, con estenosis derecha del 50 %, disminución del flujo de la arteria vertebral izquierda y obstrucción proximal de la arteria subclavia izquierda proximalmente. El síndrome del robo de la subclavia es una entidad poco frecuente, su diagnóstico es clínico y se demuestra mediante doppler o angiografía. El tratamiento debe ser decidido individualmente en cada caso.

Título: Avaliação da artéria cerebral média na restrição do crescimento fetal de início tardio / Assessment of middle cerebral artery in late fetal growth restriction
Fonte: Femina;42(2):83-86, mar-abr. 2014. tab.
Idioma: pt.
Resumo: Desde a última década, a restrição do crescimento fetal tem sido classificada em duas formas: de início precoce e tardio. Este último, em geral, tem início após 32 semanas e cursa com maior morbidade perinatal. Um grande desafio nos dias atuais consiste na diferenciação dos fetos pequenos constitucionais dos restritos de início tardio. Apesar do Doppler da artéria umbilical ser normal em ambos os casos, nas formas tardias de restrição de crescimento fetal, outros parâmetros podem estar associados a resultados perinatais adversos e à morbidade neurológica. Entre eles, destacam-se as alterações do Doppler da artéria cerebral média e a relação cérebro-placentária. Vários estudos foram publicados utilizando estes parâmetros no seguimento de fetos com restrição de crescimento fetal tardia, mas ainda as evidências não se mostram suficientes para a sua incorporação na prática clínica.(AU)

Since the last decade, fetal growth restriction has been classified in two ways: early or late beginning. The last one generally starts after 32 weeks and is followed by higher perinatal death rates. A great challenge nowadays consists in the differentiation of constitutional small fetuses from late growth restriction ones. Even though the Doppler of the umbilical artery is normal in both cases, in the late fetal growth restriction other parameters could be associated with adverse perinatal results and neurological morbidity. Among these, the most relevant are the alterations of the Doppler of the middle cerebral artery and the cerebroplacental ratio. Several studies have been published using these parameters in the follow-up of fetuses with late growth restriction, but the evidences are still not enough for their incorporation into clinical practice.(AU)

Resumo: O presente estudo avaliou a autorregulação encefálica (ARE) em doentes com insuficiência hepática fulminante (IHF) antes e após transplante hepático. Foram avaliados 25 pacientes com diagnóstico de IHF, 17 foram avaliados antes e após o transplante hepático, sendo seis (24,0%) do sexo masculino e 19 (76,0%) feminino. A média de idade foi de 33,8 anos, que variou de 14 a 56 anos, com desvio padrão de 13,1 anos. A hemodinâmica encefálica foi avaliada pela velocidade de fluxo sanguíneo encefálico (VFSE) nas artérias cerebrais médias e artéria basilar (AB), que usou o ultrassom Doppler transcraniano (DTC), dispositivo de dois canais, com transdutores de 2 mega Hertz (MHz). A autorregulação encefálica foi mensurada pelo índice de autorregulação (IARE) estática que leva em conta os efeitos do aumento da pressão arterial média (PAM) sobre a VFSE. Para isso, promoveu-se o aumento da PAM (20 mmHg a 30 mmHg) com infusão de noradrenalina.. Ao se avaliar o IARE considerando a velocidade de fluxo sanguíneo em quatro momentos (pré-transplante, 1°, 2° e 3° dia após o transplante), observou-se que houve diferença estatística em artéria cerebral média (ACM) à direita (p=0,008), esquerda (p=0,007), máxima (p=0,005), e AB (p=0,006); assim como na análise em cada tempo do IARE, observou-se diferença estatística em ACM à direita (p=0,012), esquerda (p=0,009), máxima (p=0,006), e AB (p=0,011). A análise categórica do IARE na artéria cerebral média e basilar descreveu que a maioria dos doentes reestabeleceu a AR no 2° dia em ACM e 3° na AB (índice > 0,6), enquanto com o índice > 0,8 em ambas as artérias a ARE reestabeleceu no 2° dia. As variáveis sistêmicas como pressão parcial de CO2 e hemoglobina nos tempos da avaliação não apresentaram diferença estatística p=0,100 e p=0,093 respectivamente. Os resultados obtidos apontam para o comprometimento da ARE antes e após transplante hepático, tanto em circulação anterior como posterior, e que tende a ser reestabelecido entre 48...

This study evaluated cerebral autoregulation in patients with fulminant hepatic failure (FHF) before and after liver transplantation. A total of 25 patients comprising six (24.0%) males and 19 (76.0%) females with FHF were evaluated. Seventeen patients were evaluated both before and after liver transplantation. Mean age of the patients was 33.8 years, with a range of 14-56 years and standard deviation of 13.1 years. Brain hemodynamics was assessed by cerebral blood flow velocity in the middle cerebral arteries (MCA) and basilar artery (BA) using transcranial Doppler ultrasound on a two-channel device with 2 MHz transducers. Cerebral autoregulation was measured by static cerebral autoregulation index (SCAI), which accounts for the effects of increase in mean arterial blood pressure (ABP) on cerebral blood flow velocity. An increase in ABP (20 mmHg to 30 mmHg) was induced with norepinephrine infusion. Evaluation of SCAI based on blood flow velocity (BVF) at four timepoints (pre-transplant and on 1st, 2nd and 3rd days post-transplant) revealed a statistical difference in the MCA right (p = 0.008) left (p = 0.007), maximum (p = 0.005) and the BA (p = 0.006). In addition, analysis by timepoint showed a statistical difference in MCA (p = 0.012), left (p = 0.009), maximum (p = 0.006) and in the BA (p = 0.011). Categorical analysis of autoregulation in the MCA and BA showed that most patients reestablished autoregulation in the MCA on the 2nd day post-transplant and in the BA (index > 0.6) on the 3rd day, while autoregulation was reestablished in both arteries (index > 0.8) on the 2nd day. On the assessment by timepoint, the systemic variables CO2 partial pressure and hemoglobin showed no statistically significant differences (p = 0.100 and p = 0.093, respectively). The results reveal impaired SCAI before and after liver transplantation, both in anterior and posterior circulation, with a tendency to reestablish at 48 to72 hours. The findings of this study can help...
