ABSTRACT

INTRODUÇÃO: Recém-nascidos pré-termo (RNPT) com menos de 27 semanas de idade gestacional apresentam vulnerabilidade para o desenvolvimento de hemorragias peri e intraventriculares (HPIV), o que pode afetar a mielinização e organização do córtex cerebral, acarretando possíveis prejuízos ao desenvolvimento. OBJETIVO: Avaliar o comportamento neurológico de RNPT acometido por HPIV com e sem sepse segundo a versão resumida do Método Dubowitz, delimitar a presença de itens desviantes da avaliação e comparar com as respostas obtidas pelo grupo controle (sem HPIV). MÉTODOS: Estudo transversal realizado no Hospital Municipal Universitário de São Bernardo do Campo (SP). Os RNPT foram divididos em três grupos, sendo dois estudos (HPIV e HPIV + sepse) e um controle. Os participantes foram avaliados com idade correspondente ao termo. A versão resumida do método, utilizada como triagem para recém-nascidos de risco neurológico é constituída por 12 itens. As análises foram realizadas segundo pontuações desviantes nestes itens e comparadas com as pontuações esperadas para a normalidade. Os dados obtidos foram comparados na pontuação resumida e na pontuação da versão íntegra. RESULTADOS: A frequência de RNPT com pontuações atípicas foram: 40% no grupo HPIV + sepse, 10% no grupo HPIV e 15% no controle. CONCLUSÃO: A HPIV de forma isolada não parece ser um fator significante para presença de itens desviantes no Método Dubowitz resumido. A presença de HPIV em graus mais severos esteve associada à presença de sepse. Os RNPT com HPIV associada à sepse obtiveram pior desempenho neurológico.


INTRODUCTION: Preterm infants with less than 27 weeks of gestacional age present vulnerability for development of periand intraventricular hemorrhage (PIVH). This can affect the myelinization and organization of cerebral cortex, leading to possible developmental impairment. OBJECTIVE: To evaluate the neurological behavior of preterm infants affected by PIVH with and without sepsis according to the Dubowitz Method summary, to delimit the presence of deviant items of the evaluation and to compare with the results of the control group (without PIVH). METHODS: This is a cross-sectional study. The preterm infants were divided in three groups, two study groups (PIVH and PIVH + sepsis), and one control group. The summary version of the Dubowitz Method was used as a neurological screening for the risk in preterm infants. The analysis was performed according to scores with deviation in these items and compared to the expected normal score. Data obtained were compared using the summary score and the full version of the test. RESULTS: The frequency of abnormal scores was: 40% in the group with PIVH + sepsis, 10% in the group only with PIVH, 15% in the control group. CONCLUSION: The PIVH does not seem to be a significant factor for the presence of items with deviation in the summary version of Dubowitz Method. The presence of PIVH in more severe stages was associated with the presence of sepsis. The preterm infants with PIVH with sepsis obtained worse neurological performance in the test.

ABSTRACT

Introdução As doenças cerebrovasculares (DCV) são a principal causa de morte no Brasil, sendo um grande problema de saúde pública em todo o mundo. Métodos Revisão da literatura utilizando o banco de dados do MEDLINE. Buscados os termos "intracerebral" e "hemorrhage" presentes no título e no resumo publicados em qualquer data. Resultados As hemorragias intracranianas (HIC) acometem, principalmente, os lobos cerebrais, gânglios da base, tálamo, tronco cerebral (predominantemente a ponte) e cerebelo como resultado da ruptura de vasos cerebrais afetados pelos efeitos degenerativos da hipertensão arterial sistêmica (HAS) ou da angiopatia amiloide. O diagnóstico pode ser feito através da tomografia computadorizada de crânio (TCC), sendo auxiliado pela ressonância nuclear magnética (RNM) do encéfalo e a angiografia dos quatro vasos cerebrais na investigação etiológica. Tratamento: dividido em clínico e cirúrgico. Atualmente, não há consenso sobre a seleção do tipo de tratamento para pacientes com HIC, e esta decisão deve levar em consideração idade do paciente, estado neurológico, tamanho e profundidade do hematoma, presença de hidrocefalia e de efeito compressivo. Os estudos atuais mostram uma tendência de superioridade dos procedimentos cirúrgicos minimamente invasivos, commenor risco de lesão encefálica secundária decorrente do acesso cirúrgico ao hematoma. Conclusão A escolha da melhor estratégia para o tratamento das HIC permanece um desafio e ainda deve ser feita de forma individualizada.


Introduction Cerebrovascular Diseases are the major cause of death in Brazil and a public health issue in the world. Methods Review of the literature using the MEDLINE's data bank. We have searched the keywords "intracerebral" and "hemorrhages" in the title and abstract. Results Intracranial hemorrhages (ICH) affect, mainly, the cerebral lobes, basal ganglia, thalamus, brain stem and the cerebellum as a result of the rupture of diseased cerebral vessels by the effects of hypertension or amyloid angiopathy. Diagnosis can be done with the use of a non-contrast computed tomography (CT), magnetic resonance imaging (MRI) and cerebral angiogram (useful in investigation of the etiology). Treatment can be divided in clinical and surgical. This decision still should be taken considering individual features, such as patient's age and neurological status, hematoma's size and deep, time between ictus and the procedure, presence of hydrocephalus and compressive effects. The studies has shown a preference for the minimally invasive procedures, since the secondary brain lesions caused by the surgery tend to be less. Conclusion The choice of what would be the best strategy to treat the ICH is still a challenge and this decision should be taken individually.

ABSTRACT

Pusher behavior (PB) is a disorder of postural control affecting patients with encephalic lesions. This study has aimed to identify the brain substrates that are critical for the occurrence of PB, to analyze the influence of the midline shift (MS) and hemorrhagic stroke volume (HSV) on the severity and prognosis of the PB. We identified 31 pusher patients of a neurological unit, mean age 67.4±11.89, 61.3 percent male. Additional neurological and functional examinations were assessed. Neuroimaging workup included measurement of the MS, the HSV in patients with hemorrhagic stroke, the analysis of the vascular territory, etiology and side of the lesion. Lesions in the parietal region (p=0.041) and thalamus (p=0.001) were significantly more frequent in PB patients. Neither the MS nor the HSV were correlated with the PB severity or recovery time.


A síndrome do empurrador (SE) é um distúrbio de controle postural que acomete indivíduos com lesões encefálicas. Os objetivos deste estudo foram identificar as estruturas encefálicas envolvidas na SE, analisar a influência dos desvios de linha média (DLM) e volume do hematoma (VH) na gravidade e duração da SE. Dentre os pacientes internados na enfermaria de neurologia, foram identificados 31 pacientes com SE, idade média 67,4±11,89, 61,3 por cento homens. Foram realizados exames neurológico e funcional. As análises das neuroimagens incluíram medidas de VH em pacientes com doença cerebrovascular (DC) hemorrágica, DLM, análise do território vascular, etiologia e lado da lesão. Lesão nas regiões parietal (p=0,041) e talâmica (p=0,001) foram significativamente mais frequentes nos pacientes com SE. Não foi observada correlação dos DLM e volume do hematoma com a gravidade e duração da SE.

ABSTRACT

Revisão sobre as doenças cerebrovasculares hemorrágicas (DEVH), com ênfase emsua fisiopatologia, avaliando a utilização de um agente hemostático de ação localizada — fator VII recombinante ativado (rFVIIa) — no contexto de agente neuroprotetor. Método: Como ferramenta de busca, utilizamos Medline, Scielo e Cochraine cruzando os termos: “rFVIIa intracranial hemorrhage”;“penumbra zone”; “intracranial trauma rFVIIa”; “hemorrhagic stroke rFVIIa”, selecionados do período de 1995-2008. Avaliamos trabalhos que mostraram a utilização do rFVIIa em situações neurológicas críticas, incluindo traumatismo craniencefálico, hemorragia subaracnóidea, hematomas sub e extradurale hemorragia intraventricular, tendo como parâmetros valores referentes ao tempo de protrombina, tempo de tromboplastina parcial ativada e índice de normalização internacional antes e após a utilização desse agente hemostático.


Literature review about hemorrhagic cerebrovascular disease, emphasizing its pathophisiology, and evaluating the utilization of a local action hemostatic factor — activated recombinant factor VII(rFVIIa) — as a neuroprotective agent. Method: In Medline, Scielo and Cochraine data bases thefollowing searching words were used: “rFVIIa intracranial hemorrhage”; “penumbra zone”; “intracranialtrauma rFVIIa”; and “hemorrhagic stroke rFVIIa”. Publications between 1995 and 2008 on the use of rFVIIa in critical neurologic situations, such as traumatic brain injury, subarachnoid hemorrhage, subdural and extradural haematoma, and inraventricular hemorrhage, using prothrombin time, partial activated tromboplastin time, and the international normalization ratio before and after its administration as control parameter were selected.

ABSTRACT

Intracranial haemorrhage in typhoid fever is very rare. We report another case of non-traumatic intracranial hemorrhage in a 6-year-old boy suffering from typhoid fever, unconsciousness, seizure and non-coherent speech. Investigations revealed severe thrombocytopenia and prolonged prothrombin time. CT scan of brain showed intraparenchymal haemorrhage in frontal regions bilaterally with perilesional oedema, subarachnoid bleed and extension into the lateral ventricles. No aneurysm or arterio-venous malformation was seen on MR angiography. The patient recovered without any neurological deficit

ABSTRACT

This study compared the results of neurodevelopmental examination at 6 months' corrected age of premature infants with neonatal seizures and/or intracranial hemorrhage and normal premature infants. There was a statistically significant correlation (p=0.000007) between intracranial hemorrhage and seizures in the group of 68 premature infants seen in the neurodevelopmental outpatient service at Hospital de Clínicas de Porto Alegre, Brazil. Intracranial hemorrhage was significantly associated with multiparity (p=0.02). The neurodevelopmental examination at 6 months' corrected age revealed that patients who suffered neonatal intracranial hemorrhage and/or seizures had inappropriate muscle tone, strength and reflexes, as well as delay in head control. Conclusion: we compared the results of neurodevelopmental examinations of two groups of premature infants at 6 months' corrected age. The difference in neurological development at 6 months' corrected age was statistically significant when comparison was corrected for premature infants who had neonatal seizures and periventricular hemorrhage
