    Full Text Available Los abscesos cerebrales por Propionibacterium acnes son poco frecuentes. Es importante para el médico clínico la rápida identificación de este patógeno para la elección de una terapéutica antibiótica adecuada. En este caso se describe un paciente con una exéresis de un glioblastoma multiforme donde a los 9 meses se evidenció la existencia de una recidiva tumoral, se efectuó una extirpación tumoral subtotal y la colocación de implantes de quimioterapia en el lecho tumoral residual. Al cabo de un mes de esta reoperación presentó una lesión ocupante compatible con un absceso cerebral, motivo por el cual se realizó nueva craneotomía y drenaje del mismo. En los cultivos de las biopsias y del material purulento se aisló P. acnes como flora única. Para la identificación se realizaron pruebas bioquímicas y se aplicó el sistema API20A. Se determinó la concentración inhibitoria mínima (CIM a clindamicina, penicilina, amoxicilina y metronidazol, los valores de CIM (ug/ml obtenidos fueron: 0.250, 0.040, 0.023 y 256, respectivamente. El paciente recibió cefepime más metronidazol por vía endovenosa durante un período de 30 días y completó tratamiento con clindamicina por vía oral durante 60 días, dada la posible complicación ósea en el sitio de la infección. Luego de 8 meses de la intervención quirúrgica y el drenaje del absceso cerebral no hubo evidencia de signos clínicos de recidiva tumoral e infecciosa. P. acnes es un patógeno infrecuente como causal de abscesos cerebrales, sin embargo no se debe desestimar en muestras neuroquirúrgicas.Brain abscesses by Propionibacterium acnes are rare. The rapid identification of this pathogen is important in order to choice the appropriate antibiotic therapy. We describe the case of a patient with excision of a multiform glioblastoma who 9 months later presented a tumor recurrence. A subtotal tumor excision was made and implants chemotherapy were placed in the residual tumor

    Full Text Available La paracoccidioidomicosis es una micosis sistémica, endémica de áreas tropicales y subtropicales de América Central y del Sur, causada por un hongo dimorfo denominado Paracoccidioides brasiliensis. El compromiso del sistema nervioso central es una rara complicación de la forma diseminada crónica de la enfermedad y puede comprometer el cerebro, el cerebelo, el tronco cerebral y la médula espinal. La forma clínica más común de la neuroparacoccidioidomicosis es el granuloma o absceso cerebral y, con menos frecuencia, la meningoencefalitis crónica. Se presenta un paciente con diagnóstico de paracoccidioidomicosis diseminada crónica con múltiples lesiones cerebrales compatibles con abscesos. La biopsia estereotáxica seguida del estudio histopatológico y microbiológico del material obtenido de las lesiones permitió observar las levaduras redondeadas con los brotes característicos de Paracoccidioides brasiliensis.Paracoccidioidomycosis is an endemic systemic disease in subtropical areas of Central and South America caused by a dimorphic fungus Paracoccidioides brasiliensis. Central nervous system involvement is a rare complication of the chronic disseminated disease that can affect the brain, cerebellum, brainstem and the spinal cord. The most frequent clinical form of neuroparacoccidiodomycosis is the cerebral abscess; with less frequency, the disease presents as a diffuse chronic meningoencephalitis. Here we present a patient with diagnosis of disseminated paracoccidioidomycosis and multiple cerebral lesions compatible with abscesses. Stereotactic biopsy followed by the microbiological and histopathological examination of the smears showed the characteristic yeast cells that confirmed the diagnosis of neuroparacoccidioidomycosis.

    Full Text Available La nocardiosis del sistema nervioso central (SNC es una enfermedad poco común, cuya frecuencia ha aumentado con el crecimiento de los tratamientos inmunosupresores. El hombre se infecta por inhalación, inoculación traumática cutánea directa y tras una infección periodontal ingiriendo alimentos contaminados. La localización pulmonar es la más frecuente, siendo la fuente inicial de diseminación hemática, con predominio en piel, tejido celular subcutáneo y SNC. Es conocida la predilección de Nocardia por el SNC. Estos abscesos, asociados a altos índices de mortalidad, especialmente en pacientes inmunocomprometidos, siguen constituyendo un desafío diagnóstico y terapéutico, permaneciendo no aclarado su manejo terapéutico óptimo. A pesar de la controversia en cuanto al manejo quirúrgico de estas lesiones, el diagnóstico precoz, por aspiración esterotáxica, y la iniciación de una terapia antimicrobiana son esenciales para la buena evolución del paciente. Se presenta una paciente portadora de una poliglobulia primaria, con absceso cerebral recidivante por Nocardia asteroides de posible origen dentario.Nocardiosis of the central nervous system (CNS is an uncommon disease, but its frequency has increased due to the high number of immunosuppressive treatments. People become infected by inhalation, direct traumatic cutaneous inoculation and eating contaminated food after a periodontal abscess. Lung localization is the most frequent one, being the origin of haematic dissemination, with a high incidence in skin, subcutaneous tissue and the CNS. The preference of Nocardia for the CNS is well-known. These abscesses are a diagnostic and therapeutic challenge, since they are associated to high mortality rates, specially in immunocompromised patients; the best therapeutic management remains unclear. In spite of the existing controversy with regard to the surgical management of these lesions, an early diagnosis through stereotactic

    Full Text Available Yersinia enterocolitica es un cocobacilo gram negativo de amplia distribución mundial cuyo reservorio natural se encuentra en una gran variedad de animales. La transmisión a los humanos se realiza principalmente a través de la vía fecal-oral aunque también se han descrito casos de transmisión a través de transfusiones sanguíneas. Su aislamiento se realiza habitualmente dentro de un cuadro gastrointestinal y rara vez produce trastornos extraintestinales como bacteriemia, abscesos, manifestaciones cutáneas, etc. Éstos se han asociado a diferentes enfermedades de base como alteraciones del metabolismo del hierro, diabetes mellitus, alcoholismo, malnutrición, tumores, terapia inmunosupresora y cirrosis. Presentamos el caso de un paciente diabético que desarrolló bacteriemia asociada a abscesso hepático por Yersinia enterocolitica.Yersinia enterocolitica is a Gram-negative coccobacillus that is distributed world-wide and whose natural reservoire is found in a great variety of animals. Transmission to humans mainly occurs through the faecal-oral path although cases have been described of transmission through blood transfusions. It is isolated within a gastro-intestinal clinical picture and it rarely produces extra-intestinal disorders such as bacteraemia, abscesses, cutaneous signs, etc. The latter have been associated with different underlying diseases such as alterations of the iron metabolism, diabetes mellitus, alcoholism, malnutrition, tumours, immunosuppressant therapy and cirrhosis. We present the case of a diabetic patient who developed bacteraemia associated with hepatic abscess due to Yersinia enterocolitica.

    Full Text Available La enfermedad de Rendu-Osler-Weber es una enfermedad autosómica dominante que se manifiesta por telangiectasias en piel y mucosas y malformaciones arteriovenosas en diversos órganos. El compromiso neurológico puede ocurrir por la presencia de malformaciones arterio-venosas cerebrales, hemorragia intracraneal, y más habitualmente por accidentes cerebrovasculares isquémicos y abscesos cerebrales secundarios a embolia paradojal, en pacientes con malformaciones arteriovenosas pulmonares. El absceso intramedular es una entidad rara, inusual como complicación de la enfermedad de Rendu-Osler-Weber. Presentamos el caso de una mujer de 56 años de edad, con antecedentes familiares de enfermedad de Rendu-Osler- Weber, que ingresó a Terapia Intensiva con cuadriplejia aguda e hipoxemia, en quien se diagnosticó fístulas arteriovenosas pulmonares y un absceso intramedular cervical.Rendu-Osler-Weber syndrome is an autosomal dominant disorder characterized by multiple skin and mucosal telangiectasis and multiorgan arteriovenous malformations. Neurological manifestations may occur because of cerebral arteriovenous malformations, intracranial hemorrhage, and most commonly by ischemic stroke and brain abscess secondary to paradoxical embolization in patients with pulmonary arteriovenous malformations. Intramedullary abscess is a rare, unusual condition, in Rendu-Osler-Weber syndrome. We report the case of a 56 years old woman, with a familial history of Rendu-Osler-Weber syndrome, admitted to intensive care with acute quadriplegia and hypoxemia. Our diagnosis was pulmonary arteriovenous malformations and intramedullary abscess.

    Full Text Available Cerebral aspergillosis is a rare cause of brain expansive lesion in AIDS patients. We report the first culture-proven case of brain abscess due to Aspergillus fumigatus in a Brazilian AIDS patient. The patient, a 26 year-old male with human immunodeficiency virus (HIV infection and history of pulmonary tuberculosis and cerebral toxoplasmosis, had fever, cough, dyspnea, and two episodes of seizures. The brain computerized tomography (CT showed a bi-parietal and parasagittal hypodense lesion with peripheral enhancement, and significant mass effect. There was started anti-Toxoplasma treatment. Three weeks later, the patient presented mental confusion, and a new brain CT evidenced increase in the lesion. He underwent brain biopsy, draining 10 mL of purulent material. The direct mycological examination revealed septated and hyaline hyphae. There was started amphotericin B deoxycholate. The culture of the material demonstrated presence of the Aspergillus fumigatus. The following two months, the patient was submitted to three surgeries, with insertion of drainage catheter and administration of amphotericin B intralesional. Three months after hospital admission, his neurological condition suffered discrete changes. However, he died due to intrahospital pneumonia. Brain abscess caused by Aspergillus fumigatus must be considered in the differential diagnosis of the brain expansive lesions in AIDS patients in Brazil.La aspergilosis cerebral es una causa rara de lesión expansiva cerebral en pacientes con SIDA.

    Cerebral toxoplasmosis is a disease that affects many AIDS's patients. FOr this paper 46 patients with confirmed cases of cerebral toxoplasmosis who did a CT scan between March, 1994 and September, 1997 were examined. Single lesions were found in 28.3% of the patients. The lesions were more frequently detected in the basal ganglia and the frontal lobes. No lesion was larger than 4 cm. As regards the contrast enhancing of the lesions on a CT scan we observed that 54.5% of the lesions had a ring-like contrast enhancing, 36.4% had a nodular contrast enhancing and 6% had a heterogeneous form. After the 21st day of treatment we noticed an improvement in the aspect of the patients'lesions. The improvement of the lesions could be seen through a reduction of the edematous halo, a reduction of the lesion size and a modification in the contrast enhancing on the CT scan. The CT scan was an important method to demonstrate the lesions compatibility enhancing on the CT scan. The CT scan was an important method to demonstrate the lesions compatibility with cerebral toxoplasmosis, as well as to monitor these patients during treatment. (author)

    Full Text Available Considerando que os estudos sobre a relação profissional de saúde e cliente contribuíram para o surgimento da proposta do modelo humanizado de atendimento, esta pesquisa investigou os possíveis sentimentos de fisioterapeutas em relação ao atendimento de pessoas com paralisia cerebral, já que esta condição, a paralisia cerebral, é considerada sem cura pela medicina e com possibilidades de melhora diretamente vinculadas aos exercícios fisioterapêuticos. Utilizando um instrumento contendo perguntas abertas, foram realizadas entrevistas com fisioterapeutas que atendem aos casos com sequelas mais graves: ausência total da linguagem verbal e comprometimentos motores que levam os pacientes à situação de acamados. Mediante a análise de conteúdo, verificou-se que a paralisia cerebral é reconhecida pelos fisioterapeutas como um quadro neurológico e as limitações no alcance de resultados terapêuticos são vistas como normais. Assim, as mudanças, mesmo sendo reduzidas e obtidas em longo prazo, tornam o atendimento gratificante para os fisioterapeutas por representarem uma superação de desafios.Considering the studies about professional relation among health and clients contributted to arise the purposes about a humanized model of assistance. This research shows the physiotherapists' feelings on attending people with cerebral palsy, taking in accounting the cerebral palsy is presented by the medicine as a reverseless decease and having possibilities of changing entailed to the physiotherapy. By means of interviews and questionaries answered by physiotherapists, and using the contents of analysis, we can notice that the cerebral palsy is understood by the professional of physiotherapy like a neurological condition, so the limitations on reaching are noticed as normal. Thus, even the changes reduced in the long run, they make the attendance to be rewarding for the professional of physiotherapy, because these changes represent the

    Full Text Available La infección por Entamoeba histo­lytica puede causar disentería y absceso hepático amebiano, enfermedades de alta morbi-mortalidad. Los estudios seroepidemio­lógicos han demostrado que la mayoría (81-100% de los pacientes con absceso hepático amebiano y hasta la mitad en la colitis amebiana desarrollan inmuno­globulina G (IgG específica para E. histolytica, que persiste por varios años. Por tal motivo, hay controversia acerca de la utilidad de la prueba de ELISA IgG para el diagnóstico de absceso hepático amebiano en países tropicales, donde se ha reportado una alta prevalencia de la enfermedad. Se presenta el seguimiento, durante 32 meses, mediante IgG de un paciente de 69 años, proveniente del Chocó en Colombia, con diagnóstico de absceso hepático amebiano, comprobado mediante ecografía, ELISA para IgG, e inmunodifusión y por la respuesta al tratamiento con metronidazol. Las pruebas inmunodiagnósticas han permanecido positivas durante el seguimiento.Entamoeba histolytica causes dysentery and amebic liver abscess diseases, with high morbid and mortality. Seroepidemiological surveys have shown that 81-100% of patients with amebic liver abscess and 50% of patients with amebic colitis developed specific anti-E. histolytica IgG antibodies which may persist for several years. For this reason the usefulness of the ELISA test for IgG antibodies in amebic liver abscess diagnosis has been questioned in tropical countries where prevalence of the disease is high. This paper presents the follow-up during 32 months of the IgG antibodies in a 69 year old patient from Chocó (Colombia, with one amebic liver abscess confirmed by liver ultrasound, ELISA IgG and inmunodifution, who response to treatment with metronidazole. The immunodiagnostic tests have been consistently positive during follow-up.

    Full Text Available Cerebral ischemic processes associated with infective endocarditis caused by Streptococcus bovis are rare; only 2 cases having been reported. Here we report a case of a 50-year-old man with S. bovis endocarditis who presented signs of frontal, parietal and occipital lobe cerebral ischemia. This is the first case reported in which the presence of hemianopsia preceded the endocarditis diagnosis. Initially, the clinical manifestations suggested a systemic vasculitis. Later, vegetating lesions were identified in the aortic valve and S. bovis grew in blood cultures. Antibiotic use and aortic valve replacement eliminated the infection and ceased thromboembolic events. A videocolonoscopy examination revealed no mucosal lesions as a portal of entry in this case, although such lesions have been encountered in up to 70% of reported cases of S. bovis endocarditis.A associação de isquemia cerebral e endocardite por Streptococcus bovis é um evento raro, tendo sido publicados apenas 2 casos anteriormente. Nós relatamos o caso de um homem de 50 anos com endocardite por S. bovis que apresentou sinais isquêmicos nos lobos frontal, parietal e occipital. Este é o primeiro caso em que a hemianopsia precedeu o diagnóstico de endocardite. Inicialmente, o quadro foi confundido com vasculite. Posteriormente, foi confirmada a presença de vegetações na válvula aórtica e a hemocultura identificou S. bovis. Os eventos tromboembólicos foram controlados com o uso de antibióticos e a troca da válvula aórtica. Estudo videocolonoscópico não identificou nenhuma lesão, apesar de lesões colônicas serem descritas em até 70% dos casos de indivíduos com endocardite por S. bovis.

    Directory of Open Access Journals (Sweden)

    Joel Ramírez-Emiliano

    2007-04-01

    Full Text Available El óxido nítrico participa en funciones fisiológicas y fisiopatológicas, así como en el mecanismo de defensa del sistema inmunológico de mamíferos contra parásitos, virus y bacterias. La Entamoeba histolytica es un parásito protozoario causante de la amebiasis, la cual se caracteriza por el daño intestinal y la formación del absceso hepático amebiano (AHA. El desarrollo del absceso hepático amebiano en el hámster es similar al que desarrolla el humano, mientras que el ratón es resistente a la formación de este absceso, debido a un incremento en la producción de óxido nítrico. A diferencia del ratón, el desarrollo del absceso hepático amebiano en el hámster es debido a un exceso en la producción de óxido nítrico o posiblemente a una mayor susceptibilidad del hámster al daño producido por el óxido nítrico. Por lo tanto, sería importante realizar más estudios para determinar si en el humano, un exceso en la producción de óxido nítrico favorece la formación del absceso hepático amebiano.Nitric oxide participates in both physiological and pathophysiological functions, and it plays an important role in the mammalian immune system in killing or inhibiting the growth of many pathogens, including parasites, viruses and bacteria. Entamoeba histolytica is a protozoan parasite that causes amoebiasis, which is characterized by intestinal damage and amoebic liver abscess development. The development of amoebic liver abscess in hamsters is similar to that in humans, whereas mice are resistant to amoebic liver abscess development due to an increase in nitric oxide production. Unlike in mice, amoebic liver abscess development in hamsters is due to an excess in nitric oxide production or possibly to a greater susceptibility of the hamster to damage caused by nitric oxide. Therefore, it could be important to elucidate if, in humans, an excess in nitric oxide production favors amoebic liver abscess development.

    Full Text Available El absceso del músculo psoas ilíaco (AP, es una entidad clínica poco frecuente y de presentación insidiosa, pero de importancia creciente. Descrito inicialmente como una tríada de dolor, fiebre y dificultad en la deambulación, rara vez se presenta así, ya que en general la clínica es inespecífica. En los últimos años ha ocurrido un cambio en el espectro etiopatogénico de los AP, con un aumento relativo en la descripción de los AP piógenos de origen primario, lo que adquiere relevancia en pacientes inmunosuprimidos, más frecuentes en la actualidad. Los abscesos primarios tienen incidencia variable, siendo cercana al 95% en países subdesarrollados y tropicales, 60% en Estados Unidos y 20% en Europa. Suelen ser unilaterales (98%, más frecuentes en menores de 30 años y de sexo masculino (75%. El 88% son producidos por estafilococo aureus, preferentemente monomicrobianos. En los últimos años ha ocurrido un aumento del número de casos diagnosticados, debido posiblemente a la disponibilidad de mejores técnicas diagnósticas, al aumento de la prevalencia de enfermedades crónicas y los casos de inmunosupresión.

    Full Text Available Trata-se de estudo prospectivo abrangendo 92 doentes com infarto cerebral (IC. O seguimento foi feito durante 10 dias com avaliação diária, sendo os doentes analisados por escala de notas para diferentes sinais costumeiramente pesquisados nesses casos. A metodologia foi especialmente desenvolvida no sentido de analisar exclusivamente alterações devidas ao edema oriundo da isquemia e IC. As conclusões foram obtidas por comparação isolada das médias das notas de cada sinal com a média do total das notas. Os resultados mostram que o exame da «consciência», isoladamente, é o melhor parâmetro clínico para averiguar a evolução do doente após um IC, sem outras complicações que não o edema.

    Full Text Available Cerebral phaeohyphomycosis ("chromoblastomycosis" is a rare intracranial lesion. We report the first human culture-proven case of brain abscesses due to Fonsecaea pedrosoi in Brazil. The patient, a 28 year-old immunocompetent white male, had ocular manifestations and a hypertensive intracranial syndrome. Magnetic resonance imaging (MRI of the brain revealed a main tumoral mass involving the right temporo-occipital area and another smaller apparently healed lesion at the left occipital lobe. A cerebral biopsy was performed and the pathological report was cerebral chromoblastomycosis. The main lesion was enucleated surgically and culture of the necrotic and suppurative mass grew a fungus identified as Fonsecaea pedrosoi. The patient had received a knife wound sixteen years prior to his hospitalization and, more recently, manifested a pulmonary granulomatous lesion in the right lung with a single non-pigmented form of a fungus present. It was speculated that the fungus might have gained entrance to the host through the skin lesion, although a primary respiratory lesion was not excluded. The patient was discharged from the hospital still with ocular manifestations and on antimycotic therapy and was followed for eight months without disease recurrence. Few months after he had complications of the previous neuro-surgery and died. A complete autopsy was performed and no residual fungal disease was found.A Feohifomicose cerebral ("cromoblastomicose" é uma lesão rara.

Los factores de riesgo más frecuentemente encontrados fueron grietas del pezón e ingurgitación mamaria (95%. Staphylococcus aureus (SA fue el responsable de 82.3 a 95.0% de los abscesos según los años; la resistencia a oxacilina de las cepas de SA superó el 60%. Las cepas aisladas de SA meticilino resistentes (SAMR fueron sensibles a eritromicina clindamicina, gentamicina, rifampicina, ciprofloxacina y trimetroprima-sulfametoxasol en diferentes porcentajes según los años. Requirieron drenaje el 100% de los casos; en 60% el tratamiento empírico inicial fue inadecuado. Continuaron amamantando 90% de las madres. Estos datos enfatizan la necesidad de prevenir los factores de riesgo: grietas del pezón e ingurgitación mamaria. La modificación del tratamiento antibiótico inicial requiere el estudio bacteriológico de las infecciones de piel y partes blandas dado que la prevalencia de SAMR no es uniforme y varía en diferentes poblaciones y ubicaciones geográficas.

Foram estudados 20 pacientes admitidos nas primeiras 48 horas após o início dos sintomas e randomizados para o International Stroke Trial, estudo multicêntrico de avaliação de drogas antitrombóticas. Foi utilizado o protocolo de R. S. Goldman e col. (1996 de avaliação de duração de internação, frequência e razões alegadas para a permanência hospitalar não justificada (PHNJ. O tempo médio (média ± desvio padrão de internação para os 20 pacientes foi 13,1 ± 11,5 dias (mediana=10 dias. Doze pacientes (60% tiveram um ou mais dias de PHNJ. Nestes 12 pacientes, 83 (62% dos 134 dias de internação foram considerados desnecessários (6,9 ± 4,6. A principal razão alegada para PHÑJ nestes pacientes foi a necessidade de realização de exames complementares disponíveis no hospital, como ecocardiograma transtorácico e duplex-scan dos vasos cervicais. A idade, o sexo, o local de internação do paciente ou a necessidade de transferência não se associaram ao tempo de hospitalização. Em conclusão, a duração da hospitalização após o infarto cerebral pode ser drasticamente reduzida pela otimização do uso de métodos diagnósticos disponíveis no hospital estudado.The frequency and causes of prolonged length of stay (LOS in patients with acute ischemic stroke were studied in 20 patients admitted to a university hospital participating in the International Stroke Trial (1ST.

    Full Text Available Las enfermedades cerebrovasculares son consecuencia de una alteración en la circulación cerebral. Su forma más distintiva de presentación es el ictus, entendido como un déficit neurológico focal de instauración brusca y evolución rápida. Un infarto cerebral de origen oclusivo puede deberse bien a una trombosis in situ o bien a una embolia procedente de un foco distante. En las embolias cerebrales la causa principal son los trombos murales cardiacos y el área encefálica afectada con mayor frecuencia es el territorio irrigado por la arteria cerebral media. Presentamos el caso de una mujer de 81 años, con antecedentes de Hepatitis C, cardiopatía hipertensiva y fibrilación auricular crónica, que sufrió una fractura de cadera consecutiva a una caída accidental. Durante el ingreso hospitalario comenzó un cuadro de deterioro neurológico progresivo que no llegó a ser filiado, falleciendo 9 días después. En la autopsia médico-forense se encontró un infarto cerebral hemorrágico en el territorio de la arteria cerebral media izquierda. Dado que las arterias del Polígono de Willis eran permeables y ante la presencia de trombos vitales adheridos a la pared del ventrículo derecho, se estimó como causa más probable del accidente vasculocerebral la embolización de uno de dichos trombos.Cerebrovascular diseases are due to a disturbance in cerebral blood flow. The most frequent way of presentation is stroke, defined as a sudden and focal neurological impairment with rapid evolution. Cerebral infarction of occlusive origin can be secondary to in situ thrombosis or to embolism from a distal focus. Mural thrombi are the main cause of brain embolism and the middle cerebral artery territory is the most likely affected brain area. We report the case of an 81 year-old woman, with antecedents of Hepatitis C, hypertensive cardiopathy and chronic atrial fibrillation, who suffered a hip fracture due to an accidental fall.

  16. Cerebral malaria Malaria cerebral

    Full Text Available Is the most common complication of P. falciparum malaria; nearly 90% of people who have suffered CM can recover without neurological problems. Currently there are four hypotheses that explain pathogenesis of CM: cytoadherence and sequestering of parasitized red blood cells to cerebral capillaries; rosette formation and parasitized red blood cells agglutination; production of cytokines and activation of second messengers and opening of the blood-brain barrier. However the main question remains to be answered; how the host-parasite interaction in the vascular space interferes transiently with cerebral function? Recently, the beta amyloid precursor peptide has been employed as marker of neural injury in CM. It is expected that the beta amyloid precursor peptide will help to understand the pathogenesis of CM in complicated patients of endemic areas of Colombia. La malaria Cerebral (MC es la complicación más frecuente de la malaria por P. falciparum; aproximadamente el 90% de las personas que la han padecido se recuperan completamente sin secuelas neurológicas. Aún no se conoce con claridad su patogénesis pero se han postulado cuatro hipótesis o mecanismos posibles: 1 citoadherencia y secuestro de glóbulos rojos parasitados en la microvasculatura cerebral; 2 formación de rosetas y aglutinación de glóbulos rojos parasitados; 3 producción de citoquinas y activación de segundos mensajeros y, 4 apertura de la barrera hematoencefálica. Sin embargo, queda un interrogante sin resolver aún: ¿qué proceso se lleva a cabo para que el parásito, desde el espacio microvascular, pueda interferir transitoriamente con la función cerebral? Recientemente se ha utilizado el precursor de la proteína b-Amiloide como un marcador de daño neuronal en MC; este precursor será de gran ayuda en futuras investigaciones realizadas en nuestro medio que aporten información para comprender la patogénesis de la MC.

    Full Text Available Dor central produzida por tumores cerebrais é considerada rara pela maioria dos autores. Os poucos casos descritos na literatura fazem referência à dor central provocada pela presença de lesões expansivas acometendo o córtex parietal contralateral. Nem mesmo os tumores talâmicos costumam produzir dor central. Apresentamos dois casos de dor central associada a lesões expansivas que acometeram o córtex parietal, 1 astrocitoma low grade e 1 meningioma. Em ambos houve alívio da dor após a remoção cirúrgica das lesões.Central pain derived from cerebral tumors is considered rare by most authors. The few cases described in literature refer to central pain caused by expansive lesions in the contralatral parietal cortex. Usually, not even thalamic tumors cause central pain. We describe two cases of central pain related to expansive lesions in the parietal cortical region -- a low grade astrocytoma and a meningioma. Both patients reported pain relief after lesions were removed by surgery.

    The percutaneous drainage of a pelvic abscess is a radiological and operational procedure that has gained great acceptance as an assistance to the antibiotic or surgical treatment. We describe our experience in draining pelvic abscesses guided by Ct, with a trans abdominal or transgluteal approach. The choice of approach is made taking into account the location of the abscess, the type of pathology, the technology available and the operators experience. We drained 27 pelvic abscesses using percutaneous procedures and a radiological guide (CT or fluoroscope CT). A follow up of the patients was carried out, collecting information on the drainage time, the amount drained, the etiology, the assistance treatment, when it was necessary, and the complications observed. 96.2% of the cases were successful (26 out of the 27 patients). The most frequent etiology corresponding to our cases were abscesses with an enteral origin, especially the appendicular ones. We consider this technique to be of great diagnostic and therapeutic value for a lot of the pelvic abscesses detected, being the technique to be chosen for patients who are high risk for surgery.

    Full Text Available O aumento no número de separação/divórcio favorece o surgimento de novas estruturas familiares. Nesse sentido, o recasamento desponta como uma possibilidade de ordenamento do grupo familiar, que impõe à nova família uma reorganização, sobretudo nas vidas afetiva, social e econômica, assim como maior flexibilidade para negociar questões de associação, espaço, autoridade e tempo. O objetivo deste artigo foi descrever a estrutura e a dinâmica de uma família recasada, na qual há uma criança com paralisia cerebral, a partir de suas representações acerca de situações de conflito. Neste estudo de caso, foi pesquisada uma família, constituída, por três membros, mãe, filho e padrasto; foram aplicados um roteiro de entrevista semiestruturado e o Family System Test (FAST. Os escores obtidos no FAST demonstraram proximidade na díade mãe-filho e distanciamento na díade padrasto-enteado, com a hierarquia concentrada na mãe; quanto à flexibilidade das fronteiras, a percepção do casal indicou fronteiras rígidas tanto no sistema familiar quanto no parental, diferenciando-se da percepção do filho sobre o sistema familiar com uma fronteira difusa. Portanto, alguns fatores destacados na literatura e presentes nessa família como: diferença no ciclo de vida do casal; pouco tempo de união; bagagem emocional entre mãe e filho, associados às demandas de cuidado da criança, seus recursos biopsicológicos e disposições; configuraram um padrão rígido, com baixa flexibilidade, o que dificulta a inserção do padrasto no grupo e, consequente, assunção de co-paternidade nos cuidados e criação do enteado.The increase in the number of separation/divorce has favored the emergence of new family structures.

    Full Text Available Relata-se caso de paciente de 22 anos vítima de traumatismo cranioencefálico penetrante por fragmento de fibra de amianto medindo 15 x 12 cm, e seu tratamento bem sucedido por craniectomia descompressiva. Ao contrário da lesão encefálica por projétil de arma de fogo, lesão encefálica penetrante por objeto de baixa energia é incomum. A maioria dos casos relatados na literatura envolve lesões cranio-orbitárias ou autoflagelação em pacientes psiquiátricos. O caso relatado torna-se especial em virtude das grandes dimensões do objeto penetrante, do tratamento por craniectomia descompressiva e do bom resultado funcional alcançado.We report the case of a 22-year-old man victim of penetrating brain injury due to a 15 x 12 asbestos fragment and a successfully treatment via decompressive craniectomy. Unlike gunshot wounds to the head, penetrating brain injury from low energy objects are unusual. Most cases reported involve cranio-orbitary injuries as well as self inflicted lesions in mentally ill patients. The reported case is noteworthy due to the large dimensions of the foreign body, the treatment via decompressive craniectomy and the good patient functional outcome.

    Full Text Available Es reconocido el compromiso del sistema nervioso periférico en la etapa crónica de la enfermedad de Chagas, incorporándose últimamente evidencias tomográficas y neuropsicológicas de compromiso cerebral. Con el objetivo de evaluar dicho compromiso por medio del potencial P 300 y la electroencefalografía cuantificada (EEGc se estudiaron 35 pacientes (26 a 55 años, comparados con un grupo control de similar número y edad (29 a 55 años. Se observó: latencia de la onda P 3 mayor en el grupo en estudio (331,24 ± 24,02 contra 318,86 ± 23,18 (p=0,01716. El EEGc mostró diferencias en la potencia relativa de la banda Beta 1, menor en los pacientes (p=1,62834E5 y en la frecuencia dominante, 1 Hz menor en los chagasicos (p=0,01077. El análisis multivariado discrimina tres subpoblaciones: una normal, una de enfermos con incremento alfa y otra de enfermos con decremento alfa e incremento delta y theta (p=0,00004. La proporción de resultados patológicos fue del 20 % en los EEGc y el 11,43 % en los potenciales cognitivos. No se correlacionó el compromiso neurológico y el cardíaco. Se concluye que existen francos indicadores electrofisiológicos de compromiso cerebral en el estadio crónico de la enfermedad de Chagas, hallazgo que refuerza a los obtenidos por otros métodos.

    Full Text Available Multidetector computed tomography (MDCT scanning has enabled the early diagnosis of hyperacute brain ischemia. We aimed at validating a standardized protocol to read and report MDCT techniques in a series of adult patients. The inter-observer agreement among the trained examiners was tested, and their results were compared with a standard reading. No false positives were observed, and an almost perfect agreement (Kappa>0.81 was documented when the CT angiography (CTA and cerebral perfusion CT (CPCT map data were added to the noncontrast CT (NCCT analysis. The inter-observer agreement was higher for highly trained readers, corroborating the need for specific training to interpret these modern techniques. The authors recommend adding CTA and CPCT to the NCCT analysis in order to clarify the global analysis of structural and hemodynamic brain abnormalities. Our structured report is suitable as a script for the reproducible analysis of the MDCT of patients on suspicion of ischemic stroke.A tomografia computadorizada multidetectores (TCMD permitiu o diagnóstico precoce de isquemia cerebral hiperaguda. O presente estudo objetivou validar a interpretação e a descrição padronizada de um protocolo de TCMD multiparamétrica em uma série de pacientes adultos.

    Full Text Available La variedad de opiniones que se levantan con el propósito de explicar con alguien grado de proximidad la mente del hombre, resultan ocasionalmente incompletas, pero cada una de esas afirmaciones termina por hacer parte, de una solo concepción donde todas las posibilidades tanto neurofisiológicas como psicológicas se pueden aplicar. Partiendo de la apreciación que la conciencia es la máxima expresión de la evolución mental, por ser una facultad que implica interacción de funciones mentales superiores, podríamos tener bajo cierta medida una aproximación a lo que implica la actividad mental, conociendo que el cerebro implica mecanismos fisiológicos y químicos con una funcionalidad que probablemente se moldee con el tiempo. Existen diferentes mecanismos implicados en la actividad mental superior, algunos como la memoria, se explican bajo razones fisiológicas, otros, necesitan una análisis más profundo para intentar cuando menos entender como suceden. Nuestro psiquismo no progresa únicamente por la vía de la maduración mecánica de aptitudes biológicas, condicionadas estas por el sistema nervioso central, este se organiza y desarrolla en el procedimiento de la necesidad humana de interactuar con el medio y relacionarse con sus semejantes.

    Objective: to describe and compare imaging methods and clinical findings of cerebral venous thrombosis in four full-term neonates without brain damage, admitted to a neonatal intensive care unit. Materials and methods: ten-year review of four cases diagnosed with cerebral venous thrombosis by transfontanellar ultrasonography associated with Doppler fluxometry and confirmed by magnetic resonance imaging/magnetic resonance angiography in correlation with clinical findings and neurological progression. Results: ultrasonography presented normal results in 75% of cases and magnetic resonance imaging in 100%. Doppler fluxometry and magnetic resonance angiography were abnormal in 100% of cases. Hypoxia (100%) and early seizures (100%) were predominant among clinical findings with evoked potential changes in 50% of cases. In the assessment of the neuro development all the areas remained within normality parameters up to the conclusion of the present study. Conclusion: ultrasonography in association with Doppler can identify changes related to cerebral venous thrombosis and should be complemented with magnetic resonance imaging that is the gold standard for diagnosis in these cases.

Os dados foram coletados através de um protocolo de avaliação junto a cinco alunos com paralisia cerebral e formulário aplicado aos diretores das instituições de ensino, sendo analisados por meio das categorias suscitadas. Os resultados apontaram a presença de mobiliário escolar que não atende as necessidades específicas de posicionamento dos alunos avaliados e a ausência do fisioterapeuta na prescrição desse mobiliário. Constata-se a necessidade dos órgãos gestores no âmbito da educação de Natal/RN em cumprir o que determina a lei e disponibilizar mobiliário escolar adequado aos alunos pesquisados. Assim, procurou-se garantir os recursos necessários para promover um ensino de qualidade para os educandos com paralisia cerebral no contexto da escola regular.The objective of this study was to evaluate the conditions of school furniture available for students with cerebral palsy in public schools in the city Natal, Rio Grande do Norte in 2008, looking at how physical therapists participated in the process of prescribing such furniture. The data was collected using an evaluation protocol with students with cerebral palsy and with school principals who filled out forms. The analysis was undertaken according to the categories that arose from the data. The results indicated that: 1 school furniture doesn’t meet the specific positioning needs of the students that were evaluated and 2 physical therapists do not participate in prescribing appropriate furniture. The study showed that in Natal, Rio Grande do Norte, educational administrators need to carry out the policies that have been determined by law in order to make proper school furniture available to students with cerebral palsy.

    Full Text Available Paresthesiae-producing deep brain stimulation (stimulation of ventrocaudal nucleus - VC, medial lemniscus - ML or internal capsule - IC is one of the few procedures to treat the steady element of neural injury pain (NIP currently available. Reviewing the first 60 patients with NIP submitted to deep brain stimulation (DBS from 1978 to 1991 at the Division of Neurosurgery, Toronto Hospital, University of Toronto, we observed that 6 patients complained of unpleasant paresthesiae with paresthesiae-producing DBS, preventing permanent electrode implantation in all of them. Such patients accounted for 15% of the failures (6 out of 40 failures in our series. In an attempt to improve patient selection, we reviewed our patients considering a number of parameters in order to determine risk factors for unpleasant paresthesiae elicited by paresthesiae-producing DBS. The results showed that this response happenned only in patients with brain central pain complaining of evoked pain, secondary to a supratentorial lesion. Age, sex, duration of pain, quality of the steady pain, size of the causative lesion and site (VC,ML,IC and type (micro or macroelectrode of surgical exploration were not important factors. Unpleasant paresthesiae in response to dorsal column stimulation, restricted thalamic lesion on computed tomography and the occurrence of associated intermittent pain were considered major risk factors in this subset of patients and the presence of cold allodynia or hyperpathia in isolation and the absence of sensory loss were considered minor risk factors. It is our hope that the criteria here established will improve patient selection and so, the overall results of DBS.A estimulação cerebral profunda (ECP de sítios cuja estimulação elicita parestesia (núcleo talâmico ventrocaudal - VC, lemnisco medial - LM e cápsula interna - CI é um dos poucos métodos atualmente disponíveis para o tratamento do elemento constante da dor por injúria neural (DIN

    Full Text Available Vasoespasmo cerebral ocorre em patologias como enxaqueca, hemorragia subaracnóidea, trauma de crânio, após isquemia e/ou hipoxia. A fisiopatologia do vasoespasmo cerebral nestas patologias não está completamente desvendada. Neste artigo são analisados os fatores neuroquímicos e morfológicos responsáveis pelo controle circulatório cerebral. As alterações circulatórias que seguem a hemorragia subaracnóidea são utilizadas como exemplo. Conclui-se que fatores bioquímicos, fisiológicos e morfológicos são responsáveis pelas manifestações vasculares que ocorrem após a hemorragia subaracnóidea. Alternativas de tratamento do vasoespasmo cerebral são discutidas.

    1975-01-01

    The first case of cerebral paragonimiasis was reported by Otani in Japan in 1887. This was nine years after Kerbert's discovery of the fluke in the lungs of Bengal tigers and seven years after a human pulmonary infection by the fluke was demonstrated by Baelz and Manson. The first case was a 26-year-old man who had been suffering from cough and hemosputum for one year. The patient developed convulsive seizures with subsequent coma and died. The postmortem examination showed cystic lesions in the right frontal and occipital lobes. An adult fluke was found in the occipital lesion and another was seen in a gross specimen of normal brain tissue around the affected occipital lobe. Two years after Otani's discovery, at autopsy a 29-year-old man with a history of Jacksonian seizure was reported as having cerebral paragonimiasis. Some time later, however, it was confirmed that the case was actually cerebral schistosomiasis japonica. Subsequently, cases of cerebral paragonimiasis were reported. However, the majority of these cases were not confirmed histologically. It was pointed out that some of these early cases were probably not Paragonimus infection. After World War II, reviews as well as case reports were published. Recently, investigations have been reported from Korea, with a clinicla study on 62 cases of cerebral paragonimiasis seen at the Neurology Department of the National Medical Center, Seoul, between 1958 and 1964. In 1971 Higashi described a statistical study on 105 cases of cerebral paragonimiasis that had been treated surgically in Japan.

    Full Text Available OBJECTIVES: The pioneering performance of gamma probe-assisted surgery (GPAS for brain tumors, aiming not only an improvement of tumor detection, but mainly assurance of its complete removal and the study of the usual distribution of the 99mTc-MIBI in the brain SPECT of normal individuals. METHOD: Patient's informed consent and demonstration of the tumor by the preoperative MIBI SPECT were the inclusion criteria adopted for GPAS, which was performed in one patient with a right parietal lobe metastatic tumor. The radiotracer (99mTc-MIBI was injected in a peripheral vein 5 hours before the operation. A tumor to-normal tissue count ratio equal to or greater than 2/1 was considered indicative of tumor. MIBI SPECT was performed in five normal individuals in a pilot study. RESULTS: The gamma probe greatly facilitated intraoperative tumor detection (tumor to-normal brain count ratio was 5/1 and indicated a small piece of residual tumor after what was thought to be a complete tumor removal, allowing its resection, which, otherwise, would have been left behind. Postoperative CT confirmed complete tumor resection. The MIBI SPECT in normal individuals showed an increased uptake by the hypophisis, choroid plexus, skull, scalp and salivary glands and absence of uptake by the normal brain tissue. There were no complications. CONCLUSION: GPAS proved to be, in this single case, a safe and reliable technique to improve brain tumor detection and to confirm the presence or absence of residual tumor.OBJETIVOS: A realização pioneira de cirurgia assistida por detector gama (CADG para tumores cerebrais, objetivando-se não apenas a identificação do tumor, mas, sobretudo, assegurar-se quanto à sua completa ressecção e estudar a distribuição usual do 99mTc-MIBI no SPECT cerebral de indivíduos normais.

El objetivo del estudio fue evaluar la acción del midazolam utilizado como medicación preanestésica sobre el índice bispectral (EEG-BIS de los pacientes con parálisis cerebral. MÉTODO: Se evaluaron dos grupos de pacientes: uno con diagnóstico de PC y el otro sin enfermedad del sistema nervioso central (SNC y periférico. Se registraron valores de EEG-BIS en la enfermería en la víspera de la operación y el día de la operación, 40 minutos después de la administración de 0,6 mg.kg-1 de midazolam por vía oral. Quedaron excluidos pacientes con historial de reacción paradoxal al midazolam y pacientes del grupo control que estuviesen usando otra medicación. RESULTADOS: Se estudiaron 77 pacientes de ambos sexos, entre 4 y 18 años de edad. No hubo diferencia entre los valores de EEG-BIS basal entre los grupos estudiados. Después del uso del midazolam hubo una reducción de los valores del EEG-BIS en los dos grupos estudiados, con diferencia estadística significativa en cada grupo. En la comparación entre los grupos no hubo diferencia estadística. CONCLUSIONES: El midazolam administrado como medicación preanestésica en la dosis de 0,6 mg.kg-1 redujo los valores basales del EEG-BIS sin caracterizar la hipnosis y sin diferencia estadística en los grupos estudiados.BACKGROUND AND OBJECTIVES: Midazolam is a benzodiazepine with hypnotic action widely used as pre-anesthetic medication in pediatric anesthesia.

The syndromes are characterized by having a common cause, motor defects. It is important, because they can cause a brain damage by presenting motor defects and some associated deficiencies, such as mental deficiency, epilepsy, language and visual defects and pseudobulbar paralysis, with the nonevolving fact. Some authors prefer using terms such as "non-evolving encephalopathies". In the treatment the utility of prevention programs of early stimulation and special rehabilitation methods, and treatment of associated deficiencies such as epilepsy, mental deficiency, language, audition and visual problems, and the attention deficit improve the prognosis in an important way. The prognosis depends on the severity of the disease and the associated manifestations.

    Cerebral microangiopathies are a very heterogenous group of diseases characterized by pathological changes of the small cerebral vessels. They account for 20 - 30 % of all ischemic strokes. Degenerative microangiopathy and sporadic cerebral amyloid angiography represent the typical acquired cerebral microangiopathies, which are found in over 90 % of cases. Besides, a wide variety of rare, hereditary microangiopathy exists, as e.g. CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy), Fabrys disease and MELAS syndrome (Mitochondrial myopathy, Encephalopathy, Lactic Acidosis, and Stroke-like episodes).

    Introduccion. Las celulas madre constituyen una alternativa terapeutica que se encuentra en fase de experimentacion para el infarto cerebral. Objetivo. Mostrar la evidencia cientifica existente sobre el potencial terapeutico de las celulas madre de la medula osea en esta enfermedad. Desarrollo. El infarto cerebral representa el 80% de las enfermedades cerebrovasculares. La trombolisis constituye la unica terapia aprobada, pero, por su estrecha ventana terapeutica, solo se aplica a un bajo porcentaje de los pacientes. De manera alternativa, los tratamientos neurorrestauradores, como el de celulas madre, pueden aplicarse en periodos mas prolongados. Por esta razon se efectuo una busqueda bibliografica en PubMed con el empleo de las palabras clave 'stem cells', 'bone marrow derived mononuclear cells' y 'stroke'. Se encontraron evidencias de seguridad y eficacia de dichas celulas en diferentes momentos evolutivos del infarto cerebral. Se identificaron estudios que en clinica y preclinica las recolectaron por puncion medular y en sangre periferica, y las trasplantaron directamente en el area infartada o por via intravascular. El efecto terapeutico se relaciona con sus propiedades de plasticidad celular y liberacion de factores troficos. Conclusiones. El concentrado de celulas mononucleares autologas, obtenido en sangre periferica o por puncion de la medula osea, y trasplantado por via intravenosa, es una factible opcion metodologica que permitira rapidamente incrementar el numero de ensayos clinicos en diferentes etapas evolutivas del infarto cerebral. Esta terapia muestra seguridad y eficacia; sin embargo, deben ampliarse las evidencias que avalen su generalizacion en humanos.

We present our experience with ultrastructural analysis in 582 exams of ocular conjunctiva (n=320, skin (n=92 or peripheral nerve (n=170 performed between 1975 and 1996, in 486 children. In 112 cases there were definit ultrastructural changes. In 59 cases, the sole ultrastructural exam allowed the diagnosis. In 29, the changes were less specific, and the final diagnosis was performed by a combination of clinical and pathological analysis. In the remaining 24 cases, a generic diagnosis of mucopolysaccharidosis was done in 8 cases, oligosaccharidosis in 4 cases and GM2 gangliosidosis in 12 cases. Whenever a biochemical test was performed in overseas laboratories, the initial diagnosis was confirmed.

    We evaluated six children in whom MR imaging showed unilateral cerebral polymicrogyria associated with ipsilateral cerebral atrophy and ipsilateral brain stem atrophy. The aim of this study was to clarify whether this disorder based on neuroimaging constitutes a new homogeneous clinical entity. The subjects were six children whose ages at the time of MR imaging ranged from 8 months to 11 years. Their clinical and MR features were analyzed. All of the children were born between 38 and 42 weeks gestation, without any significant perinatal events. Spastic hemiplegia and epilepsy were observed in all of the patients, and mental retardation was observed in four. The MR findings included unilateral cerebral polymicrogyria associated with ipsilateral cerebral hemiatrophy and ipsilateral brain stem atrophy in all patients. The ipsilateral sylvian fissure was hypoplastic in four patients. These patients showed relatively homogeneous clinical and neuroimaging features. Although the additional clinical features varied according to the site and the extent affected by the polymicrogyria, this disorder could constitute a new relatively homogeneous clinical entity.

    Full Text Available INTRODUCTION: Sleep disorders presenting involuntary movements may be very annoying to patients, apart from their negative influence on sleep. OBJECTIVE: To report the use of botulinum type-A toxin (BoNT-A to manage the case of a patient whose sleep was severely disrupted by episodes of dystonic posturing of the right lower limb triggered by periodic limb movements of sleep (PLMS. METHOD: A 79-year-old woman with mild post-stroke right hemiparesis presented with recurrent painful episodes of dystonia of the right lower limb, which disrupted her sleep. The dystonic episodes could also be voluntarily triggered by extension of the right hallux. Polysomnography confirmed that the dystonic episodes were triggered by PLMS. Twenty units of BoNT-A (20U/500U vial were injected into her right extensor hallucis longus. RESULTS: Shortly after BoNT-A was injected, the dystonic symptoms abated, and the patient achieved better sleep efficiency. CONCLUSION: The PLMS-related involuntary extension of the hallux was probably triggering the nocturnal post-stroke lower limb dystonic paroxysms. BoNT-A injection into the right extensor hallucis longus was effective in managing this condition and thus resolved the associated disruption of sleep.INTRODUÇÃO: Desordens do sono apresentando movimentos involuntários podem ser bastante perturbadoras aos pacientes, além de sua influência negativa no sono.

    1. Cerebral arteries and veins were demonstrated by multiplane computed cerebral angiotomography (combination of axial, modified coronal, half axial (Towne), and semisagittal planes). The vessels which were demonstrated by various planes were as follows: Axial plane: Willis ring, middle cerebral arteries (horizontal and insular portions), anterior cerebral arteries (Horizontal and ascending portions), posterior cerebral arteries, basal vein of Rosenthal, internal cerebral veins (and the subependymal veins which join the ICV), and vein of Galen. Coronal plane: intermal carotid arteries (supraclinoid portion), anterior cerebral arteries (horizontal portion), middle cerebral arteries (horizontal and insular portions), lenticulostriate arteries, basal vein of Rosenthal (and the subependymal veins which join this vessel), internal cerebral veins, and vein of Galen. Half axial plane (Towne projection): basilar artery, vertebral arteries, posterior cerebral arteries, superior cerebellar arteries, middle cerebral arteries (horizontal portion), and anterior cerebral arteries (horizontal and ascending portions). Semisagittal plane: internal carotid artery (supraclinoid portion), posterior communicating artery, posterior carebral artery, superior cerebellar artery, internal cerebral vein, basal vein of Rosenthal, vein of Galen, and straight shinus. 2. A detailed knowledge of normal cerebrovascular structures acquired by computed tomography (CT) is essential in detecting and more precisely localizing lesions such as cerebrovascular disease, neoplasm or abscess, in differentiating these lesions from the normal contrast-enhanced structures, and in understanding the spatial relationship between the mass lesion and the neighboring vessels. In addition, it will be possible to discover such asymptomatic cerebrovascular diseases as non-ruptured aneurysms, arteriovenous malformations, and Moyamoya disease by means of computed cerebral angiotomography.

Injury to the developing brain that occurs either in utero or soon after birth can result in the motor, sensory, and cognitive deficits seen in cerebral palsy. Although the etiologies for cerebral palsy are variable, neuroinflammation plays a key role in the pathophysiology of the brain injury irrespective of the etiology. Currently, there is no effective cure for cerebral palsy. Nanomedicine offers a new frontier in the development of therapies for prevention and treatment of brain injury resulting in cerebral palsy. Nanomaterials such as dendrimers provide opportunities for the targeted delivery of multiple drugs that can mitigate several pathways involved in injury and can be delivered specifically to the cells that are responsible for neuroinflammation and injury. These materials also offer the opportunity to deliver agents that would promote repair and regeneration in the brain, resulting not only in attenuation of injury, but also enabling normal growth. In this review, the current advances in nanotechnology for treatment of brain injury are discussed with specific relevance to cerebral palsy. Future directions that would facilitate clinical translation in neonates and children are also addressed.

    Notice points in clinical imaging of cerebral ischemia are reviewed. When cerebral blood flow is determined in acute stage of cerebral embolism (cerebral blood flow SPECT), it is important to find area of ischemic core and ischemic penumbra. When large cortex area is assigned to ischemic penumbra, thrombolytic therapy is positively adapted, but cautious correspondence is necessary when ischemic core is recognized. DWI is superior in the detection of area equivalent to ischemic core of early stage, but, in imaging of area equivalent to ischemic penumbra, perfusion image or distribution image of cerebral blood volume (CBV) by MRI need to be combined. Luxury perfusion detected by cerebral blood flow SPECT in the cases of acute cerebral embolism suggests vascular recanalization, but a comparison with CT/MRI and continuous assessment of cerebral circulation dynamics were necessary in order to predict brain tissue disease (metabolic abnormality). In hemodynamic cerebral ischemia, it is important to find stage 2 equivalent to misery perfusion by quantification of cerebral blood flow SPECT. Degree of diaschisis can indicate seriousness of brain dysfunction for lacuna infarct. Because cerebral circulation reserve ability (perfusion pressure) is normal in all areas of the low cerebral blood flow by diaschisis mechanism, their areas are easily distinguished from those of hemodynamic cerebral ischemia.

  3. [Cerebral ischemia and histamine].

    Science.gov (United States)

    Adachi, Naoto

    2002-10-01

    Cerebral ischemia induces excess release of glutamate and an increase in the intracellular Ca2+ concentration, which provoke catastrophic enzymatic processes leading to irreversible neuronal injury. Histamine plays the role of neurotransmitter in the central nervous system, and histaminergic fibers are widely distributed in the brain. In cerebral ischemia, release of histamine from nerve endings has been shown to be enhanced by facilitation of its activity. An inhibition of the histaminergic activity in ischemia aggravates the histologic outcome. In contrast, intracerebroventricular administration of histamine improves the aggravation, whereas blockade of histamine H2 receptors aggravates ischemic injury. Furthermore, H2 blockade enhances ischemic release of glutamate and dopamine. These findings suggest that central histamine provides beneficial effects against ischemic neuronal damage by suppressing release of excitatory neurotransmitters. However, histaminergic H2 action facilitates the permeability of the blood-brain barrier and shows deleterious effects on cerebral edema.

    Clinical and angiographic findings in migraine are briefly reviewed in relation to cerebral hemodynamic changes shown by regional cerebral blood flow (rCBF) studies. Three cases of migraine studied by the intracarotid xenon 133 method during attacks are reported. In classic migraine, with typical...... prodromal symptoms, a decrease in cerebral blood flow has been demonstrated during the aura. Occasionally, this flow decrease persists during the headache phase. In common migraine, where such prodromata are not seen, a flow decrease has not been demonstrated. During the headache phase of both types...... of migraine, rCBF has usually been found to be normal or in the high range of normal values. The high values may represent postischemic hyperemia, but are probably more frequently secondary to arousal caused by pain. Thus, during the headache phase rCBF may be subnormal, normal or high. These findings do...

O movimento da "neurodiversidade" deve ser inserido em um marco sociocultural e histórico mais amplo que incorpore o impacto crescente no imaginário cultural dos saberes e das práticas neurocientíficas com o paradigma do sujeito cerebral e a expansão da neurocultura. No contexto do sujeito cerebral, o cérebro responde por tudo o que outrora costumávamos atribuir à pessoa e vem se tornando um critério biossocial de agrupamento fundamental. O artigo mostra como uma ideologia solipsista, reducionista e cientificista - o sujeito cerebral - pode servir de base para a formação de identidade e de redes de sociabilidade e comunidade.This article analyzes the neurodiversity movement, organized mostly by so-called high-functioning autists, who consider that autism is not a disease to be treated, but rather a human difference that should be respected alongside other differences. The "neurodiversity" movement must be set within a wider sociocultural and historical field that incorporates the growing impact of neuroscientific knowledge and practices in the cultural imagination with the paradigm of the cerebral subject and the expansion of neuroculture. In the context of the cerebral subject, the brain accounts for all that we used to attribute to the person, and it is becoming a fundamental criterion for biosocial grouping. The article shows how a solipsist, reductionist and scientificist ideology - the cerebral subject - can act as the basis for the formation of identity and networks of sociability and community.

    Single-photon emission computed tomography (SPECT) can provide three-dimensional functional images of the brain following the injection of one of a series of radiopharmaceuticals that crosses the blood-brain barrier and distributes according to cerebral perfusion, neurotransmitter, or cell density. Applications include differentiating between the dementias, evaluating cerebrovascular disease, preoperative localization of epileptogenic foci, diagnosing movement disorders, and evaluation of intracerebral tumours, while also proving a useful research tool. Unlike positronemission tomography (PET), SPECT imaging is widely available and can be performed in any department that has access to a rotating gamma camera. The purpose of this review is to demonstrate the utility of cerebral SPECT and increase awareness of its role in the investigation of neurological and psychiatric disorders.

    Full Text Available Traumatic brain injury (TBI is on the rise, especially in today′s fast-paced world. TBI requires not only neurosurgical expertise but also neurointensivist involvement for a better outcome. Disturbances of sodium balance are common in patients with brain injury, as the central nervous system plays a major role in sodium regulation. Hyponatraemia, defined as serum sodium <135 meq/L is commonly seen and is especially deleterious as it can contribute to cerebral oedema in these patients. Syndrome of inappropriate antidiuretic hormone secretion (SIADH, is the most well-known cause of hyponatraemia in this subset of patients. Cerebral Salt Wasting Syndrome (CSWS, leading to renal sodium loss is an important cause of hyponatraemia in patients with TBI. Although incompletely studied, decreased renal sympathetic responses and cerebral natriuretic factors play a role in the pathogenesis of CSWS. Maintaining a positive sodium balance and adequate hydration can help in the treatment. It is important to differentiate between SIADH and CSWS when trying to ascertain a case for patients with acute brain injury, as the treatment of the two are diametrically opposite.

  11. Cerebral oxygenation and hyperthermia

    Directory of Open Access Journals (Sweden)

    Anthony Richard Bain

    2014-03-01

    Full Text Available Hyperthermia is associated with marked reductions in cerebral blood flow (CBF. Increased distribution of cardiac output to the periphery, increases in alveolar ventilation and resultant hypocapnia each contribute to the fall in CBF during passive hyperthermia; however, their relative contribution remains a point of contention, and probably depends on the experimental condition (e.g. posture and degree of hyperthermia. The hyperthermia-induced hyperventilatory response reduces arterial CO2 pressure (PaCO2 causing cerebral vasoconstriction and subsequent reductions in flow. During supine passive hyperthermia, the majority of recent data indicate that reductions in PaCO2 may be the primary, if not sole, culprit for reduced CBF. On the other hand, during more dynamic conditions (e.g. hemorrhage or orthostatic challenges, an inability to appropriately decrease peripheral vascular conductance presents a condition whereby adequate cerebral perfusion pressure may be compromised secondary to reductions in systemic blood pressure. Although studies have reported maintenance of pre-frontal cortex oxygenation (assessed by near-infrared spectroscopy during exercise and severe heat stress, the influence of cutaneous blood flow is known to contaminate this measure. This review discusses the governing mechanisms associated with changes in CBF and oxygenation during moderate to severe (i.e. 1.0°C to 2.0°C increase in body core temperature levels of hyperthermia. Future research directions are provided.

    Cerebral malformations are usually described following the different steps in development. Disorders of neurulation (dysraphisms), or diverticulation (holoprosencephalies and posterior fossa cysts), and total commissural agenesis are usually diagnosed in utero. In contrast, disorders of histogenesis (proliferation-differentiation, migration, organization) are usually discovered in infants and children. The principal clinical symptoms that may be a clue to cerebral malformation include congenital hemiparesis, epilepsy and mental or psychomotor retardation. MRI is the imaging method of choice to assess cerebral malformations. (orig.)

    Advancements in molecular biology have led to a greater understanding of the individual proteins responsible for generating cerebral edema. In large part, the study of cerebral edema is the study of maladaptive ion transport. Following acute CNS injury, cells of the neurovascular unit, particularly brain endothelial cells and astrocytes, undergo a program of pre- and post-transcriptional changes in the activity of ion channels and transporters. These changes can result in maladaptive ion transport and the generation of abnormal osmotic forces that, ultimately, manifest as cerebral edema. This review discusses past models and current knowledge regarding the molecular and cellular pathophysiology of cerebral edema.

    Objective: HIV enters the brain soon after infection causing neuronal damage and microglial/astrocyte dysfunction leading to neuropsychological impairment. We examined the impact of HIV on resting cerebral blood flow (rCBF) within the lenticular nuclei (LN) and visual cortex (VC). Methods: This cross-sectional study used arterial spin labeling MRI (ASL-MRI) to measure rCBF within 33 HIV+ and 26 HIV− subjects. Nonparametric Wilcoxon rank sum test assessed rCBF differences due to HIV serostatus. Classification and regression tree (CART) analysis determined optimal rCBF cutoffs for differentiating HIV serostatus. The effects of neuropsychological impairment and infection duration on rCBF were evaluated. Results: rCBF within the LN and VC were significantly reduced for HIV+ compared to HIV− subjects. A 2-tiered CART approach using either LN rCBF ≤50.09 mL/100 mL/min or LN rCBF >50.09 mL/100 mL/min but VC rCBF ≤37.05 mL/100 mL/min yielded an 88% (29/33) sensitivity and an 88% (23/26) specificity for differentiating by HIV serostatus. HIV+ subjects, including neuropsychologically unimpaired, had reduced rCBF within the LN (p = 0.02) and VC (p = 0.001) compared to HIV− controls. A temporal progression of brain involvement occurred with LN rCBF significantly reduced for both acute/early (<1 year of seroconversion) and chronic HIV-infected subjects, whereas rCBF in the VC was diminished for only chronic HIV-infected subjects. Conclusion: Resting cerebral blood flow (rCBF) using arterial spin labeling MRI has the potential to be a noninvasive neuroimaging biomarker for assessing HIV in the brain. rCBF reductions that occur soon after seroconversion possibly reflect neuronal or vascular injury among HIV+ individuals not yet expressing neuropsychological impairment.

    Full Text Available Cerebral sinus venous thrombosis (CSVT is a rare phenomenon that can be seen with some frequency in young patients. CSVT is a multifactorial condition with gender-related specific causes, with a wide clinical presentation, the leading causes differ between developed and developing countries, converting CSVT in a condition characterized by a highly variable clinical spectra, difficult diagnosis, variable etiologies and prognosis that requires fine medical skills and a high suspicious index. Patients who presents with CSVT should underwent to CT-scan venography (CVT and to the proper inquiry of the generating cause. This disease can affect the cerebral venous drainage and related anatomical structure. The symptoms may appear in relation to increased intracranial pressure imitating a pseudotumorcerebri. Prognosis depends on the early detection. Correcting the cause, generally the complications can be prevented. Mortality trends have diminished, and with the new technologies, surely it will continue. This work aims to review current knowledge about CSVT including its pathogenesis, etiology, clinical manifestations, diagnosis, and treatment.

    Radioisotope brain imaging has focused mainly on regional cerebral blood flow (rCBF). However the use of ligand which go to specific receptor sites is being introduced in pediatrics, mainly psychiatry. rCBF is potentially available in many institutions, especially with the availability of multi-headed gamma cameras. The use of this technique in pediatrics requires special attention to detail in the manner of data acquisition and handling the child. The interpretation of the rCBF study in a child requires knowledge of normal brain maturation. The major clinical use in pediatrics is epilepsy because of the advances in surgery and the frequency of complex partial seizures. Other indications in pediatric neurology include brain death, acute neurological loss including stroke, language disorders, cerebral palsy, hypertension due to renovascular disease, traumatic brain injury and migraine. There are pediatric physiological conditions in which rCBF has been undertaken, these include anorexia nervosa, autism, Gilles de la Tourette syndrome (GTS) and attention deficit disorder-hyperactivity (ADHD). Research using different ligands to specific receptor sites will also be reviewed in pediatrics.

    Cerebral cartography and connectomics pursue similar goals in attempting to create maps that can inform our understanding of the structural and functional organization of the cortex. Connectome maps explicitly aim at representing the brain as a complex network, a collection of nodes and their interconnecting edges. This article reflects on some of the challenges that currently arise in the intersection of cerebral cartography and connectomics. Principal challenges concern the temporal dynamics of functional brain connectivity, the definition of areal parcellations and their hierarchical organization into large-scale networks, the extension of whole-brain connectivity to cellular-scale networks, and the mapping of structure/function relations in empirical recordings and computational models. Successfully addressing these challenges will require extensions of methods and tools from network science to the mapping and analysis of human brain connectivity data. The emerging view that the brain is more than a collection of areas, but is fundamentally operating as a complex networked system, will continue to drive the creation of ever more detailed and multi-modal network maps as tools for on-going exploration and discovery in human connectomics.

    The present study observed hemodynamic changes in 26 patients with cerebral arteriosclerosis using a cerebral circulation dynamics detector and transcranial Doppler.In patients with cerebral arteriosclerosis the blood supply and flow rate in the bilateral carotid arteries and the blood flow rate in the anterior cerebral and middle cerebral arteries were similar to normal controls, but the cerebral vascular resistance, critical pressure and pulsatility index were increased, and cerebral arterial elasticity and cerebral blood flow autoregulation were decreased.Compared with the lesioned hemisphere of patients with cerebral infarction, the total blood supply and blood flow rate of patients with cerebral arteriosclerosis were higher.Compared with normal subjects, patients with cerebral arteriosclerosis exhibited cognitive disturbances, mainly in short-term memory, attention, abstract capability, and spatial and executive dysfunction.Results showed that cerebral arteriosclerosis does not directly affect the blood supply of a cerebral hemisphere, but affects cognitive function.The increased cerebral vascular resistance and reduced autoregulation of cerebral blood vessels may be important hemodynamic mechanisms of arteriosclerosis-induced cerebral infarction.

    Full Text Available Pupils with cerebral palsy attend elementary education accordind to a regular and special teaching plan and program. Regular school curriculum was reformed in 1992, while special plan and program has not been changed and adapted according to pupil’s needs and capacities. Music is one of the best means of expressing oneself and plays a very important role in the development of every child, the child with cerebral palsy in particular.In order to test the possibility of pupils with cerebral palsy, with and without mental retardation, to apprehend the actual program content, we have conducted research on musical achievement of children with cerebral palsy. During 2007 a research was carried out, on the sample of 27 pupils with cerebral palsy and mild mental retardation who attended classes in the school “Miodrag Matikj”, and a sample of16 students with cerebral palsy without mental retardation who attended the school “Dr. Dragan Hercog” in Belgrade.Results of the research, as well as analysis of music curriculum content, indicated that the capacities of students with cerebral palsy to carry out the curriculum tasks require special approach and methodology. Therefore, we introduced some proposals to overcome the difficulties in fulfilling music curriculum demands of those pupils. We made special emphasis on the use of computer based Assistive technology which facilitates the whole process to a large extent.

    Full Text Available INTRODUCTION: Cerebral palsy (CP is a group of permanent movement disorders that appear in early childhood. Cerebral palsy is caused by abnormal development or damage to the parts of the brain that control movement, balance, and posture. Most often the problems occur during pregnancy; however, they may also occur during childbirth, or shortly after birth. Often the cause is unknown. AIM: To study the different antenatal maternal risk factors associated with cerebral palsy in the study group. MATERIA LS AND METHODS: Retrospective study was done to assess possible associated antenatal risk factors for cerebral palsy. Mothers of 100 cerebral palsy children were selected who are treated in Rani Chandramani Devi Hospital, a Government hospital in Visakhapa tn am, Andhra Pradesh State, India , from 2012 to 2014 and 100 controls, mothers of normal children were studied. Detailed antenatal history was obtained from the mothers of the children in both affected and control group. RESULTS: From the data, we conclude that the association of maternal anaemia with cerebral palsy is 7.3 times higher; association of maternal hypertension with cerebral palsy is 6.6 time higher, association with Pre - eclampsia is 6 times higher; association with Eclampsia is 8.6 times higher ; with antepartum haemorrhage, the association is 8.6 times higher and association of multiple pregnancy with cerebral palsy is 4.8 times higher than with controls. CONCLUSION: From this study of the role of antenatal risk factors, in the occurrence of cer ebral palsy in children it is concluded that the most common risk factor associated with cerebral palsy is the maternal anaemia and the other important risk factors associated being hypertension, pre eclampsia, eclampsia, antepartum haemorrhage and multipl e births.

    Since 1982 (Hauser and co-workers), literature has reported focal cerebral tissue charges in AIDS patients whose diagnosis was unclear at first but which could be identified finally as florid toxoplasmosis encephalitis by biopsy and autopsy. It was found that the value of otherwise reliable serological tests (KBR, Sabin-Feldmann tests, etc.) is questionable in patients with severely impaired or incompetent immune systems, and, in particular, that a negative or uncharacteristic test result may not preclude any opportunistic infection process. Furthermore, isolation of Toxoplasma gondii or specific antibodies from the cerebrospinal fluid will be successful in exceptional cases only. In patients with AIDS or lymphadenopathy syndrome, the differential diagnosis will have to include - first and foremost - reactivated toxoplasma infection (not newly acquired, as a rule) if central neurological symptoms occur.

    Objective: To explore the strengthening of acupuncture analgesic mechanism on the level of β-endorphin and proopimelanocortin mRNA expression in the arcuate nucleus of hypothalamus in rats following electroacupuncture(EA) combined with melatonin (MEL). Methods: Integrated optical density (IOD) was measured by ABC immuno-histochemical and in situ hybridization technique with computerized image processing. The rat's brain was coronally sectioned after combination of EA and MEL. Results: IOD of β-endorphin-like immunopositive substance in rat's brain was lowered significantly, which was measured after MEL (60 mg/kg) was injected intraperitoneally and followed by EA 30 min later for 30 min, and the IOD of cerebral POMC mRNA positive substance increased significantly 10 hrs later. Conclusion:The mechanism of MEL in enhancing EA analgesic effect might be related with the release and synthesis of β-endorphin

    Summary Arterial fenestrations are an anatomic variant with indeterminate significance. Given the controversy surrounding fenestrations we sought their prevalence within our practice along with their association with other cerebrovascular anomalies. We retrospectively reviewed 10,927 patients undergoing digital subtraction angiography between 1992 and 2011. Dictated reports were searched for the terms “fenestration” or “fenestrated” with images reviewed for relevance, yielding 228 unique cases. A Medline database search from February 1964 to January 2013 generated 304 citations, 127 cases of which were selected for analysis. Cerebral arterial fenestrations were identified in 228 patients (2.1%). At least one aneurysm was noted in 60.5% of patients, with an aneurysm arising from the fenestration in 19.6% of patients. Aneurysmal subarachnoid hemorrhage or non-aneurysmal subarachnoid hemorrhage were present in 60.1% and 15.8%, respectively. For the subset of patients with an aneurysm arising directly from a fenestration relative to those patients with an aneurysm not immediately associated with a fenestration, the prevalence of aneurysmal subarachnoid hemorrhage was 66.7% vs. 58.6% (p = 0.58). Fenestrations were more often within the posterior circulation (73.2%) than the anterior circulation (24.6%), though there was no difference in the prevalence of aneurysms within these groups (61.1% vs. 60.7%, p = 1.0). Cerebral arterial fenestrations are an anatomic variant more often manifesting at the anterior communicating arterial complex and basilar artery and with no definite pathological relationship with aneurysms.

  20. Therapeutic implications of melatonin in cerebral edema.

    Science.gov (United States)

    Rathnasamy, Gurugirijha; Ling, Eng-Ang; Kaur, Charanjit

    2014-12-01

    Cerebral edema/brain edema refers to the accumulation of fluid in the brain and is one of the fatal conditions that require immediate medical attention. Cerebral edema develops as a consequence of cerebral trauma, cerebral infarction, hemorrhages, abscess, tumor, hypoxia, and other toxic or metabolic factors. Based on the causative factors cerebral edema is differentiated into cytotoxic cerebral edema, vasogenic cerebral edema, osmotic and interstitial cerebral edema. Treatment of cerebral edema depends on timely diagnosis and medical assistance. Pragmatic treatment strategies such as antihypertensive medications, nonsteroidal anti-inflammatory drugs, barbiturates, steroids, glutamate and N-methyl-D-aspartate receptor antagonists and trometamol are used in clinical practice. Although the above mentioned treatment approaches are being used, owing to the complexity of the mechanisms involved in cerebral edema, a single therapeutic strategy which could ameliorate cerebral edema is yet to be identified. However, recent experimental studies have suggested that melatonin, a neurohormone produced by the pineal gland, could be an effective alternative for treating cerebral edema. In animal models of stroke, melatonin was not only shown to reduce cerebral edema but also preserved the blood brain barrier. Melatonin's beneficial effects were attributed to its properties, such as being a potent anti-oxidant, and its ability to cross the blood brain barrier within minutes after its administration. This review summarizes the beneficial effects of melatonin when used for treating cerebral edema.

    Full Text Available The clinicopathological findings of cerebral edema were investigated in patients with acute hepatic failure autopsied at Okayama University Hospital between 1970 and 1980 retrospectively. Nine (64% of 14 hepatic failure cases were found to have cerebral edema during a post-mortem examination of the brain. Clinical features of the patients with cerebral edema were not significantly different from those of the patients without cerebral edema. However, general convulsions were observed more frequently in patients later found to have cerebral edema. Moreover, the length of time from deep coma to death was much shorter in the brain edema cases with cerebral herniation than without herniation.

    Cerebral oxygenation is not always reflected by systemic arterial oxygenation. Therefore, regional cerebral oxygen saturation (rScO2) monitoring with near-infrared spectroscopy (NIRS) is of added value in neonatal intensive care. rScO2 represents oxygen supply to the brain, while cerebral fractional tissue oxygen extraction, which is the ratio between rScO2 and systemic arterial oxygen saturation, reflects cerebral oxygen utilization. The balance between oxygen supply and utilization provides insight in neonatal cerebral (patho-)physiology. This review highlights the potential and limitations of cerebral oxygenation monitoring with NIRS in the neonatal intensive care unit. PMID:28352624

    A 60 year-old woman with a scalp epithelioma underwent radiotherapy, the dose being 57 Gray. A first epileptic seizure occurred twenty months later. Neurological examination revealed signs of left hemisphere involvement. ..gamma..EG, angiography, CT scans, demonstrated a pseudotumoral avascular process. On account of the localisation, the patient being right-handed, no surgical procedure was performed. In spite of corticotherapy and anticonvulsive treatment, seizures recurred and neurological signs slowly progressed. The patient died, 22 months after the first seizure, of an associated disseminated carcinoma with cachexia. Neuropathological examination showed a massive lesion presenting all the features of delayed radionecrosis in the left hemisphere: situated mainly in the white matter; numerous vascular abnormalities; wide-spread demyelination; disappearance of oligoglial cells. The Authors recall the clinical and anatomical aspects of this condition for which the only successful treatment is surgical removal when location and size of the lesion permit. Finally, the mechanisms which have been proposed to explain this delayed cerebral radionecrosis are discussed.

    Full Text Available A serum sodium (Na value below 135 mEq/L is evaluated as hyponatremia. Hyponatremia is the most common electrolyte abnormality observed in hospitalized patients in particular. Hypovolemic hypoosmolar hyponatremia is the most frequent clinical table. One of the reasons of this is cerebral salt-wasting syndrome (CSWS. CSWS is a rare condition progressing with low plasma osmolality, urine osmolality above 100-150 mOsm/kg and urine- Na concentration above 20 mEq/L. In the blood and urine sample analysis performed upon sudden loss of consciousness on the 15th day of the intensive care unit follow-up of 79-year-old female patients due to falling from stairs, blood biochemistry Na value was 120 mEq/L, plasma osmolality was 250 mOsm/kg, urine Na value was 180 mEq/L, urine osmolality was 1200 mOsm/kg, urine diuresis was >3 mL/kg/hour. The central venous pressure was 2 mmHg. The patient, considered to be diagnosed with CSWS, was treated with 9% NaCl and 3% hypertonic saline solution. Her clinical course was improved on the 18th day. She died on the 81st day secondary to septicemia in the subsequent follow-up. In this article, it was aimed to report a patient with CSWS which progresses with low percentage in intensive care unit patients with head trauma, is frequently confused with inappropriate antidiuretic hormone syndrome and progresses mortally when not diagnosed distinctively well.

    This was a retrospective study to determine different etiologies of cerebral venous thrombosis (CVT) in childhood and to correlate extent and location of thrombosis with the etiology and the age of the child as well as the final outcome. In addition, the radiologic approach is discussed. This was a retrospective analysis of 19 children with CVT. The children were examined by contrast-enhanced dynamic CT. Radiologic findings were correlated with the etiology of CVT. Cerebral venous thrombosis is not as infrequent in children as has been thought. Cerebral venous thrombosis in children can occur due to trauma (n=9), infections (n=7), or coagulation disorders (n=3). Extent and location of thrombosis, as well as complications, final outcome, and therapy, depend on the etiology. Computed tomography remains a valuable primary imaging modality in the diagnosis of CVT in the acutely injured or diseased child. (orig.)

    Autophagy has evolved as a conserved process for the bulk degradation and recycling of cytosolic components,such as long-lived proteins and organelles.In neurons,autophagy is important for homeostasis and protein quality control and is maintained at relatively low levels under normal conditions,while it is upregulated in response to pathophysiological conditions,such as cerebral ischemic injury.However,the role of autophagy is more complex.It depends on age or brain maturity,region,severity of insult,and the stage of ischemia.Whether autophagy plays a beneficial or a detrimental role in cerebral ischemia depends on various pathological conditions.In this review,we elucidate the role of neuronal autophagy in cerebral ischemia.

    Full Text Available Introduction Neurotoxoplasmosis (NT sometimes manifests unusual characteristics. Methods We analyzed 85 patients with NT and AIDS according to clinical, cerebrospinal fluid, cranial magnetic resonance, and polymerase chain reaction (PCR characteristics. Results In 8.5%, focal neurological deficits were absent and 16.4% had single cerebral lesions. Increased sensitivity of PCR for Toxoplasma gondii DNA in the central nervous system was associated with pleocytosis and presence of >4 encephalic lesions. Conclusions Patients with NT may present without focal neurological deficit and NT may occur with presence of a single cerebral lesion. Greater numbers of lesions and greater cellularity in cerebrospinal fluid improve the sensitivity of PCR to T gondii.

Son numerosas las pacientes que acuden a urgencias por esta causa, tanto por la clínica como por las implicaciones sociales. Los síntomas más frecuentes son dolor abdominal bajo, sangrados vaginales, o flujo vaginal excesivo o molesto. Las vulvovaginitis son uno de los problemas principales en la práctica clínica diaria del ginecólogo. La úlcera genital cuya etiología principal es el herpes, seguida de la sífilis y el chancroide incrementa el riesgo para contraer la infección por el VIH y modifica el curso de otras enfermedades de transmisión sexual. La enfermedad pélvica inflamatoria engloba a las infecciones del tracto genital superior femenino. La importancia del diagnóstico precoz y su tratamiento adecuado reside tanto por las complicaciones en la fase aguda como por las secuelas, que incluyen el dolor crónico y la esterilidad.Sexually transmitted diseases are those where the principal path of infection is through intimate contact. Numerous patients attend Accidents and emergencies for this reason, both because of the clinical features and because of social implications. The most frequent symptoms are lower abdominal pain, vaginal bleeding or excessive or troubling vaginal flow. Vulvovaginites are one of the principal problems in the everyday clinical practice of gynaecology. A genital ulcer whose principal aetiology is herpes, followed by syphilis and chancroid, increases the risk of contracting HIV infection and alters the course of other sexually transmitted diseases. Inflammatory pelvic disease encompasses infections of the upper female genital tract. The importance of early diagnosis and suitable treatment is both due to the complications in its acute phase and to its sequels, which include chronic pain and sterility.

    2015-01-01

    Cerebral ischemia is among the leading causes of death worldwide. It is characterized by a lack of blood flow to the brain that results in cell death and damage, ultimately causing motor, sensory, and cognitive impairments. Today, clinical treatment of cerebral ischemia, mostly stroke and cardiac arrest, is limited and new neuroprotective therapies are desperately needed. The Sirtuin family of oxidized nicotinamide adenine dinucleotide (NAD+)-dependent deacylases has been shown to govern several processes within the central nervous system as well as to possess neuroprotective properties in a variety of pathological conditions such as Alzheimer’s Disease, Parkinson’s Disease, and Huntington’s Disease, among others. Recently, Sirt1 in particular has been identified as a mediator of cerebral ischemia, with potential as a possible therapeutic target. To gather studies relevant to this topic, we used PubMed and previous reviews to locate, select, and resynthesize the lines of evidence presented here. In this review, we will first describe some functions of Sirt1 in the brain, mainly neurodevelopment, learning and memory, and metabolic regulation. Second, we will discuss the experimental evidence that has implicated Sirt1 as a key protein in the regulation of cerebral ischemia as well as a potential target for the induction of ischemic tolerance.

    We evaluated 35 patients with cerebral palsy on the basis of MR imaging findings in the brain. The types of palsy were spastic quadriplegia (n=11), spastic diplegia (n=9), spastic hemiplegia (n=2), double hemiplegia (n=1), athetosis (n=10) and mixed (n=2). Of all patients, 28 (80%) generated abnormal findings. In spastic quadriplegia, although eight cases revealed severe brain damage, two cases showed no abnormal findings in the brain. One of the three had cervical cord compression caused by atlanto-axial subluxation. In spastic diplegia, the findings were divided according to whether the patient was born at term or preterm. If the patient had been born prematurely, the findings showed periventricular leukomalacia and abnormally high intensity in the posterior limbs of the internal capsule on T2-weighted images. MR imaging in spastic hemiplegia revealed cerebral infarction. In the athetoid type, half of all cases showed either no abnormal findings or slight widening of the lateral ventricle. Three cases showed abnormal signals of the basal ganglia. The reason why athetoid-type palsy did not show severe abnormality is unknown. We believe that MR imaging is a useful diagnostic modality to detect damage in the brain in cerebral palsy and plays an important role in the differentiation of cerebral palsy from the spastic palsy disease.

    The usefulness and radiographic findings of the angiography in cerebral infarction are well known. We attempted to evaluate the angiographic causes, findings, and the usefulness of DSA in cerebral infarction. The authors reviewed retrospectively DSA images of 51 patients who were diagnosed as having cerebral infarction by brain CT and/or MRI and clinical settings. DSA was performed in all 51 patients, and in 3 patients, conventional angiogram was also done. Both carotid DSA images were obtained in AP, lateral, oblique projections, and one or both vertebral DSA images in AP and lateral. The authors reviewed the patient's charts for symptoms, operative findings and final diagnosis, and analysed DSA findings of cerebral atherosclerosis with focus on 6 major cerebral arteries. Among the 51 patients of cerebral infarction 43 patients (84.3%) had cerebral atherosclerosis, 1 dissecting aneurysm, 1 moyamoya disease and 6 negative in angiogram. DSA findings of cerebral atherosclerosis were multiple narrowing in 42 patients (97.7%), tortuosity in 22 (51.2%), dilatation in 14, occlusion in 12, avascular region in 8, collaterals in 7, ulcer in 6, and delayed washout of contrast media in 3. In cerebral atherosclerosis, internal carotid artery was involved in 37 patients (86.0%), middle cerebral artery in 29 (67.4%) posterior cerebral artery in 28, anterior cerebral artery in 26, vertebral artery in 22, and basilar artery in 15. Intracranial involvement of cerebral atherosclerosis (64.9%) was more common than extracranial involvement (16.2%). In cerebral infarction MRA may be the screening test, but for more precise evaluation of vascular abnormality and its extent, DSA should be considered.

    fluorescent mode this DAB reaction product selectively quenches the fluorescence of all immunopositive cells, i.e. only those neuronophages that do not bind to the primary antibody remain fluorescent. Combining FG-labeling of neuronophages with immunoquenching, a population of small round fluorescent cells was discovered, localized in the immediate vicinity of the motoneurons long after the neuronofugal migration of microglia. As the fluorescence of these cells was not quenched after a triple immunostaining with anti-neuronal-specific enolase, anti-GFAP and OX-42 (quenching all fluorescence from neurons, astroglia, and microglia), they seem to represent a new, immunologically unidentified neuronophage. Following this triple immunostaining, a broad panel of antibodies was tested to stain, quench fluorescence, and thus immunotype these enigmatic phagocytes. Only the monoclonal antibody ED2, the classical marker for perivascular cells, specifically stained the small round neuronophages. Although the perivascular cells are in the vicinity of the basal lamina of the cerebral vasculature, they must not be confused with the pericytes, which are not able to perform phagocytosis. In contrast, the perivascular cells are macrophages-ED2 recognizes an established macrophage membrane antigen. In addition, after neuronal injury a subset of the perivascular cells starts to synthesize MHC class II glycoproteins and IL-1 beta. Hence this population of cells seems to possess the complete machinery required for antigen presentation: They are macrophages, upregulate MHC class II molecules and IL-1 beta, and due to their anatomical location, have access to circulating T lymphocytes. What was still lacking, however, was a direct proof of neuronophagia. Our experiments provided this proof. (ABSTRACT TRUNCATED)

    Introduccion. La paralisis cerebral se define como un grupo de trastornos del desarrollo del movimiento y la postura que cursa con deficits cognitivos, alteraciones emocionales, de conducta y sociales. Objetivo. Estudiar la relacion entre el funcionamiento ejecutivo y la conducta en niños con paralisis cerebral a partir de las respuestas aportadas por padres y profesores en el Behavior Rating Inventory of Executive Function (BRIEF) y el sistema de evaluacion de la conducta adaptativa (ABAS-II). Pacientes y metodos. La muestra quedo formada por 46 niños con paralisis cerebral, con una edad media de 10,26 ± 2,95 años. Del total, 44 niños se distribuyeron en el Gross Motor Function Classification System (GMFCS) en nivel I (n = 16), nivel II (n = 3), nivel III (n = 11), nivel IV (n = 10) y nivel V (n = 4). Resultados. Los resultados mostraron relacion entre el BRIEF y el ABAS-II; ademas, se obtuvieron discrepancias entre las respuestas aportadas por padres y profesores, tanto en el ABAS-II como en el BRIEF. Asimismo, se hallo relacion entre el GMFCS y los subindices de vida en el hogar, indice practico y autocuidado del ABAS-II. Conclusiones. Se encontro relacion entre el funcionamiento ejecutivo y la conducta adaptativa en niños con paralisis cerebral. Se hallaron discrepancias en las respuestas aportadas por padres y profesores. Por ultimo, los datos muestran que, a mayor afectacion motora, mayores dificultades en el hogar, en el indice practico y en el autocuidado.

    Full Text Available This study demonstrates that an adrenergic mechanism plays an important role in producing the delayed cerebral vasospasm which follows subarachnoid hemorrhage. Results were as follows: 1. Experimental subarachnoid hemorrhage (SAH was produced by injection of fresh arterial blood into the cisterna magna in cats. The cerebral vasospasm was shown angiographically to be biphasic in nature: immediate constriction lasting 1 h and marked prolonged spasm occurring between the 3rd and 5th day after SAH. The amount of noradrenaline (NA and dopamine-beta-hydroxylase (DBH activity decreased over a period of 24 h both within the wall of the basilar artery and in the locus ceruleus and then gradually increased, reaching a maximum on the 3rd day after SAH. 2. Topical application of spasmogenic substances (NA and blood produced a marked constriction of the hypersensitive basilar artery on the 3rd day after SAH. 3. 6-Hydroxydopamine (6-OHDA injection into the cisterna magna produced prolonged vasocilatation. The dilated vessel responded with mild transient constriction after the topical application of NA or fresh blood. DBH activity and NA concentration in the vessels, locus ceruleus and medial hypothalamus decreased markedly on the 3rd day after the cisternal injection of 6-OHDA. 4. Various spasmogenic substances (i.e. serotonin, NA, prostaglandins and methemoglobin were measured in a mixture of equal volume of CSF and blood in cats. ONly the serotonin in the mixed fluid produced vasoconstriction. Spasmogenic substances decreased markedly in the mixed fluid incubated for 3 days at 37 degrees C, and none of these substances apart from methemoglobin was present in a concentration sufficient to produce constriction of vessels. 5. These results suggest that early spasm is induced by serotonin around the arteries of the cranial base, and delayed spasm might be caused by hyperreaction of cerebral vessels to spasmogenic substances such as methemoglobin, during the

Sin embargo, los hongos no dermatofitos, tanto hialinos como fuliginosos, pueden ser también responsables de estos cuadros clínicos. Debido a que estos hongos tienden a ser resistentes a los antimicóticos comúnmente usados para tratar las onicomicosis, es que se hace indispensable que el clínico se asegure por medio de un examen de laboratorio de la etiología de la infección. Métodos: Se estudiaron tres casos de pacientes con lesiones en uñas, que acudieron al laboratorio de Micología Médica, Facultad de Microbiología, Universidad de Costa Rica. Se realizaron los análisis de rutina para aislamiento e identificación de hongos patógenos. Resultados: En los tres casos estudiados se observó al examen directo micelio fuliginoso. En uno de los casos se aisló e identificó Scytalidium dimidiatum, hongo que presenta resistencia a los antifúngicos utilizados para tratar onicomicosis. Conclusión. El reporte de hongos diferentes a los dermatofitos como agentes etiológicos de onicomicosis es importante para que el médico pueda elegir el tratamiento más recomendado para este tipo de infección.

    This study has identified the active cerebral areas of normal Chinese that are associated with Chinese semantic processing using functional brain imaging. According to the traditional cognitive theory, semantic processing is not particularly associated with or affected by input modality. The functional brain imaging experiments were conducted to identify the common active areas of two modalities when subjects perform Chinese semantic tasks through reading and listening respectively. The result has shown that the common active areas include left inferior frontal gyrus (BA 44/45), left posterior inferior temporal gyrus (BA37); the joint area of inferior parietal lobules (BA40) and superior temporal gyrus, the ventral occipital areas and cerebella of both hemispheres. It gives important clue to further discerning the roles of different cerebral areas in Chinese semantic processing.

    Full Text Available OBJECTIVES: Discuss pathophysiological aspects of cerebral calcifications (CC and highlight its importance related to the occurrence of neuropsychiatric syndromes. METHOD: Single case report. RESULT: Man 52 years old, 20 years after going through a total thyroidectomy, starts showing behavioral disturbance (psychotic syndrome. He was diagnosed as schizophrenic (paranoid subtype and submitted to outpatient psychiatric treatment. During a psychiatric admission to evaluate his progressive cognitive and motor deterioration, we identified a dementia syndrome and extensive cerebral calcifications, derived from iatrogenic hypoparathyroidism. CONCLUSION: The calcium and phosphorus disturbances, including hypoparathyroidism, are common causes of CC. Its symptoms can imitate psychiatric disorders and produce serious and permanent cognitive sequelae. The exclusion of organicity is mandatory in any psychiatric investigative diagnosis in order to avoid unfavorable outcomes, such as in the present case report.

    Cerebral ischemia remains one of the most frequent causes of death and disability worldwide. Animal models are necessary to understand complex molecular mechanisms of brain damage as well as for the development of new therapies for stroke. This review considers a certain range of animal models of cerebral ischemia, including several types of focal and global ischemia. Since animal models vary in specificity for the human disease which they reproduce, the complexity of surgery, infarct size, reliability of reproduction for statistical analysis, and adequate models need to be chosen according to the aim of a study. The reproduction of a particular animal model needs to be evaluated using appropriate tools, including the behavioral assessment of injury and non-invasive and post-mortem control of brain damage. These problems also have been summarized in the review.

    Full Text Available Cerebral vasospasm is the first treatable cause of death and disability secondary to spontaneous subarachnoid hemorrhage due to ruptured cerebral aneurysms. However, its treatment has been disapointing with poor results. Despite the fact that the physiopathologic mechanisms governing this phenomenon are largely unknown, during the last nine years, simultaneously with the development of endovascular therapy techniques for treatment of cerebrovascular diseases, two new alternatives have emerged in order to alleviate cerebral vasospasm: intraarterial papaverine and cerebral balloon angioplasty. We report the use of intraarterial papaverine in one case to treat cerebral vasospasm presented during the endovascular therapy procedure; a review of literature is included. EI vaso espasmo cerebral es la principal causa tratable de muerte e incapacidad por hemorragia subaracnoidea espontánea secundaria a la ruptura de un aneurisma cerebral. Sin embargo, su tratamiento ha sido tradicionalmente frustrante, con resultados desalentadores. A pesar de que aún no se han aclarado del todo los mecanismos fisiopatológicos a través de los cuales ocurre este intrigante fenómeno, en los últimos 9 años, paralelamente al desarrollo de las técnicas endovasculares para el tratamiento de las enferm~dades cerebrovasculares, han surgido nuevas alternativas en el manejo del vasoespasmo cerebral. Entre ellas se destacan el uso intraarterial de papaverina y la angioplastia con balón de los vasos cerebrales. Se presenta una revisión del estado actual de estos novedosos instrumentos terapéuticos, así como el reporte de un caso en el cual usamos la papaverina intraarterial en el tratamiento del vasoespasmo quese presentó durante un procedimiento endovascular para excluir un aneurisma de la arteria cerebral media.

    Increased intracranial pressure is common in cerebral venous thrombosis (CVT), but hydrocephalus is rarely reported in these patients. We examined the frequency, pathophysiology and associated clinical manifestations of hydrocephalus in patients with CVT admitted to our hospital between 2000 and 2010 (prospectively since July 2006). Hydrocephalus was defined as a bicaudate index larger than the 95th percentile for age, and/or a radial width of the temporal horn of ≥ 5 mm. We excluded patients in whom hydrocephalus was caused by a disease other than CVT or if it was iatrogenic. 20 out of 99 patients with CVT had hydrocephalus. 6 patients with hydrocephalus were excluded from the analysis. Patients with hydrocephalus more often had focal neurological deficits (86 vs. 49%, p = 0.02) and were more frequently comatose (43 vs. 16%, p = 0.06), as compared to patients without hydrocephalus. Deep cerebral venous thrombosis (64 vs. 9%, p hydrocephalus. Intraventricular hemorrhage was present in 1 patient with hydrocephalus, compared to none among patients without hydrocephalus (7 vs. 0%, p = 0.15). Outcome at follow-up was worse in patients with hydrocephalus (mRS 0-1, 36 vs. 68%, p = 0.02; mortality 29 vs. 9%, p = 0.07). Hydrocephalus occurs more frequently in cerebral venous thrombosis than previously believed, especially in patients with deep cerebral venous thrombosis and edema of the basal ganglia. The presence of hydrocephalus is associated with a worse clinical outcome, but a direct causal relation is unlikely. Routine shunting procedures are not advisable.

    1985-01-01

    After a brief clinical and pathophysiological approach, the papers presented in this book are devoted to CT and angiography. Concerning CT, a particular study has been made of cerebral arterial territories on cuts parallel to the orbito-meatal line: these are very important in making the differential diagnosis from some tumors. Also concerning CT, a paper has been devoted to cerebral ''lacunae.'' The term ''lacuna'' as far as CT imaging is concerned, should be reserved only for those hypodense areas corresponding to small cavities containing fluid, which are sequelae of infarcts in the territory of penetrating arteries. Before this sequellar state come all the evolutive states of a small deep infarct. The angiographic study specifies the indications of angiography in the study of cerebral ischemia, and the techniques to be used. It shows the main etiologic aspects. Because of the important place of vascular surgery today, it seemed necessary to show also the main post operative angiographic aspects. After CT and angiography, some pages are reserved to more modern techniques. Finally, some pages are devoted to certain particular associations and etiologies: childhood, cardiopathies, migraine, oral contraception and end with venous infarction.

    To evaluate the MR findings of brain damage in cerebral palised patients and to correlate it with gestational age and the time of damage. A retrospective analysis was performed in 40 patients who underwent MR scanning for evaluation of brain lesion in clinically diagnosed cerebral palsy. Authors classified the patients into two groups as premature and full-term and compared MR findings of the two groups. Abnormal MR findings were noted in 28 cases (70%). Five out of 6 patients who had been born prematurely showed isolate periventricular white matter lesions. Twenty-three out of 34 patients who had been born at full-term showed abnormal MR findings. Of these 23 patients, migration anomalies in 7 patients, isolate periventricular white matter lesions in 3 patients, and other combined periventricular subcortical white matter and deep gray matter lesions in 14 patients were seen. At least, 10 patients(43%) of full term group showed abnormal MRI findings reflecting intrauterine brain damage and all 5 patients of premature group showed isolate periventricular white matter lesions suggesting immaturity of brain. MRI is thought to be very useful in the assessment of brain damage for the patients with cerebral palsy by recognizing the location of the lesion and estimating the time of damage.

    Takotsubo cardiomyopathy can induce cerebral embolic stroke because of intracardiac thrombosis, but the timing of cardiogenic embolism relating to takotsubo cardiomyopathy has not been well described. We evaluated a 71-year-old woman with takotsubo cardiomyopathy, who developed cardiogenic cerebral embolism after recovery of cardiac wall motion. Nevertheless, we treated her with anticoagulation therapy. The present clinical observation suggests that attention should be paid to the timing when takotsubo cardiomyopathy resolves against risk of cardiogenic cerebral embolism.

    Introducción: la otitis media aguda es una inflamación del oído medio frecuente en la edad pediátrica. Aproximadamente 2 % de todos los casos desarrolla complicaciones intracraneales, más específicamente meningitis; por lo general, los infartos cerebrales originados por esta última son venosos. Rara vez se ha descrito la ocurrencia de un infarto arterial cerebral como complicación directa de la otitis media aguda. Caso clínico: niña de 12 meses de edad quien fue llevada a un servicio de urgencias por síndrome febril secundario a otitis media aguda y alteración del estado de conciencia. A la exploración física se identificó que estaba somnolienta, con anisocoria, midriasis en el ojo derecho y hemiparesia izquierda. Con la tomografía axial computarizada de cerebro se apreció un infarto arterial cerebral extenso. Los padres no autorizaron la craniectomía descompresiva y la paciente falleció a las 48 horas de su ingreso hospitalario. Conclusiones: a pesar de los recursos tecnológicos con los que se dispone actualmente, el infarto cerebral relacionado con la otitis media aguda tiene una evolución tórpida. Los signos neurológicos focalizadores y el deterioro progresivo deben apuntar a la ineficacia del tratamiento antimicrobiano instaurado.

    Full Text Available Num estudo retrospectivo de 1.071 necropsias de bovinos, foram encontrados 20 casos de babesiose cerebral confirmados pelo exame de esfregaços do córtex telencefálico. A maioria desses casos ocorreu no verão, em bovinos adultos de raças européias ou suas cruzas. Além dos sinais clínicos neurológicos, observou-se hemoglobinúria, anorexia, febre, taquicardia, taquipnéia e queda na produção de leite. O hemograma realizado em cinco bovinos afetados revelou acentuada anemia regenerativa; em média, 20% dos eritrócitos estavam parasitados por Babesia bovis. Na necropsia de todos os casos, a substância cinzenta dos córtices telencefálico e cerebelar e dos núcleos da base era consistente e caracteristicamente róseo-cereja. Essa coloração devia-se ao seqüestro de eritrócitos nos capilares encefálicos. Nesses eritrócitos, podiam-se observar, tanto em esfregaços do córtex como em preparações histológicas do encéfalo, microorganismos com morfologia compatível com B. bovis. Outros achados de necropsia incluíam hemoglobinúria, rins vermelho-escuros, hepatoesplenomegalia, fígado vermelho-alaranjado, icterícia, hemorragias epicárdicas e endocárdicas e edema e congestão dos linfonodos mesentéricos.

    Hyponatremia is the most frequent electrolyte disorder in critically neurological patients. Cerebral salt wasting syndrome (CSW) is defined as a renal loss of sodium during intracranial disease leading to hyponatremia and a decrease in extracellular fluid volume. The pathogenesis of this disorder is still not completely understood. Sympathetic responses as well as some natriuretic factors play a role in this syndrome. Distinction between SIADH and CSW might be difficult. The essential point is the volemic state. It is necessary to rule out other intermediate causes. Treatment requires volume replacement and maintenance of a positive salt balance. Mineral corticoids may be useful in complicated cases.

    Cerebral oximetry based on near-infrared spectroscopy (NIRS) is increasingly used during the perioperative period of cardiovascular operations. It is a noninvasive technology that can monitor the regional oxygen saturation of the frontal cortex. Current literature indicates that it can stratify patients preoperatively according their risk. Intraoperatively, it provides continuous information about brain oxygenation and allows the use of brain as sentinel organ indexing overall organ perfusion and injury. This review focuses on the clinical validity and applicability of this monitor for cardiac surgical patients. PMID:24672700

    Clinical findings and CT findings in 73 cases of cerebral palsy were studied. The causes of cerebral palsy were presumed to be as follows: abnormal cerebral development (36%), asphyxial delivery (34%), and immature delivery (19%), etc. CT findings were abnormal in 58% of the 73 cases, 83% of the spastic tetraplegia patients and all of the spastic hemiplegia patients showed abnormal CT findings. All the patients with spastic monoplegia presented normal CT findings. In 75% of the spastic hemiplegia cases, the CT abnormalities were due to cerebral parenchymal abnormality such as porencephaly and regional low absorption. In cases of spastic tetraplegia, cerebral parenchymal abnormality was found only in 10%. Cortical atrophy was found only in 15 of the 73 cases, whereas central atrophy was found in 36 cases.

  8. Cerebral hemodynamics: concepts of clinical importance

    Edson Bor-Seng-Shu

    2012-05-01

    Full Text Available Cerebral hemodynamics and metabolism are frequently impaired in a wide range of neurological diseases, including traumatic brain injury and stroke, with several pathophysiological mechanisms of injury. The resultant uncoupling of cerebral blood flow and metabolism can trigger secondary brain lesions, particularly in early phases, consequently worsening the patient's outcome. Cerebral blood flow regulation is influenced by blood gas content, blood viscosity, body temperature, cardiac output, altitude, cerebrovascular autoregulation, and neurovascular coupling, mediated by chemical agents such as nitric oxide (NO, carbon monoxide (CO, eicosanoid products, oxygen-derived free radicals, endothelins, K+, H+, and adenosine. A better understanding of these factors is valuable for the management of neurocritical care patients. The assessment of both cerebral hemodynamics and metabolism in the acute phase of neurocritical care conditions may contribute to a more effective planning of therapeutic strategies for reducing secondary brain lesions. In this review, the authors have discussed concepts of cerebral hemodynamics, considering aspects of clinical importance.

    Full Text Available OBJECTIVE: To study the significance of electroencephalographic background activity and positive sharp waves in neonatal electroencephalogram as prognostic of cerebral palsy. METHOD: We studied prospectively and sequentially 73 newborns who had severe neonatal complications (neonatal anoxia, seizures, respiratory distress, sepsis, and meningitis. Nineteen newborns were excluded and 54 children formed the object of our study and were followed for 2 years. We analyzed gestational age, conceptional age, electroencephalographic background activity and positive sharp waves, which were correlated with cerebral palsy. RESULTS: There were no statistically significant correlation between gestational age and conceptional age and cerebral palsy; the electroencephalographic background activity was correlated with cerebral palsy as well as the positive sharp waves. CONCLUSION: Children with electroencephalographic background activity markedly abnormal and accompanied by positive sharp waves were associated with a worse prognosis.OBJETIVO: Estudar o valor do ritmo de base e das ondas agudas positivas no eletrencefalograma neonatal como prognóstico da paralisia cerebral.

Todos os pacientes apresentavam quadro neurológico muito grave, com sinais de comprometimento do tronco cerebral superior. Angiografia caro-tídea bilateral foi praticada sistematicamente, tanto no pré como no pós-operatório, constituindo-se no fator decisivo para a indicação cirúrgica. Seis (50% dos doentes sobreviveram, apresentando 5 (41,6% recuperação neurológica e psíquica praticamente totais. Levando em conta estes resultados, consideramos esta técnica cirúrgica o melhor recurso de tratamento em tais casos, máxime se indicada precocemente. São necessários, contudo, cuidados pós-operatórios especiais com estes pacientes, que devem, sempre que possível, ser mantidos em unidade de terapia intensiva, em virtude da grande incidência de complicações, mormente respiratórias.

  14. Cerebral cortex modulation of pain

    Institute of Scientific and Technical Information of China (English)

    Yu-feng XIE; Fu-quan HUO; Jing-shi TANG

    2009-01-01

    Pain is a complex experience encompassing sensory-discriminative, affective-motivational and cognitiv e-emotional com-ponents mediated by different mechanisms. Contrary to the traditional view that the cerebral cortex is not involved in pain perception, an extensive cortical network associated with pain processing has been revealed using multiple methods over the past decades. This network consistently includes, at least, the anterior cingulate cortex, the agranular insular cortex, the primary (SⅠ) and secondary somatosensory (SⅡ) cortices, the ventrolateral orbital cortex and the motor cortex. These corti-cal structures constitute the medial and lateral pain systems, the nucleus submedius-ventrolateral orbital cortex-periaque-ductal gray system and motor cortex system, respectively. Multiple neurotransmitters, including opioid, glutamate, GABA and dopamine, are involved in the modulation of pain by these cortical structures. In addition, glial cells may also be in-volved in cortical modulation of pain and serve as one target for pain management research. This review discusses recent studies of pain modulation by these cerebral cortical structures in animals and human.

A vida de Rondon é acompanhada desde a sua formação como cadete da Escola Militar, como membro da Igreja do Apostolado Positivista, como comandante da Expedição Rondon (1907-1930, que levou o telégrafo de Cuiabá a Porto Velho, e especialmente como criador e dirigente-mor do Serviço de Proteção aos Índios (SPI, 1910-1967. Rondon é o criador da expressão "Morrer se preciso for, matar nunca", que pautou a ação de indigenistas brasileiros que fizeram os primeiros contatos com muitos povos indígenas desde 1910. E muitos morreram seguindo essa norma, numa clara demonstração do novo espírito humanista criado pela atitude rondoniana. O indigenismo brasileiro implantado por Rondon teve altos e baixos ao longo de quase cem anos, que hoje prossegue pela Fundação Nacional do Índio (Funai. De fato, muitos povos indígenas perderam suas terras e muitos foram dizimados no século XX, mas os mais de 220 que sobreviveram vêm crescendo em número, obtendo suas terras (13% do território nacional e conquistando novos espaços político-culturais no Brasil.This paper reviews the life and work of Brazilian Indianist Marshall Cândido Rondon.

    Rehabilitation is a major goal for children with cerebral palsy, although the potential to enhance cardio-respiratory fitness in such individuals remains unclear. This study thus compared current cardio-respiratory status between children with cerebral palsy and able-bodied children, and examined the ability to enhance the cardio-respiratory fitness of children with cerebral palsy by cycle ergometer training. 10 children with cerebral palsy (Gross Motor Function Classification System levels I and II) participated in thrice-weekly 30 min cycle ergometer training sessions for 8 weeks (mean age: 14.2±1.9 yrs). 10 additional subjects with cerebral palsy (mean age: 14.2±1.8 yrs) and 10 able-bodied subjects (mean age: 14.1±2.1 yrs) served as controls, undertaking no training. All subjects undertook a progressive cycle ergometer test of cardio-respiratory fitness at the beginning and end of the 8-week period. Cardio-respiratory parameters [oxygen intake V˙O2), ventilation V ˙ E) and heart rate (HR)] during testing were measured by Cosmed K4 b gas analyzer. The children with cerebral palsy who engaged in aerobic training improved their peak oxygen consumption, heart rate and ventilation significantly (pchildren with cerebral palsy can benefit significantly from cardio-respiratory training, and such training should be included in rehabilitation programs.

    Ensuring adequate oxygenation of the developing brain is the cornerstone of neonatal critical care. Despite decades of clinical research dedicated to this issue of paramount importance, our knowledge and understanding regarding the physiology and pathophysiology of neonatal cerebral blood flow are still rudimentary. This review primarily focuses on currently available human clinical and experimental data on cerebral blood flow and autoregulation in the preterm and term infant. Limitations of systemic blood pressure values as surrogates for monitoring adequate cerebral oxygen delivery are discussed. Particular emphasis is placed on the high interindividual variability in cerebral blood flow values, vasoreactivity, and autoregulatory thresholds making the applications of normative values highly questionable. Technical and ethical difficulties to conduct such trials leave us with a near complete lack of knowledge on how pharmacological and surgical interventions impact on cerebral autoregulation. The ensemble of these works argues for the necessity of highly individualized care by taking advantage of continuous bedside monitoring of cerebral circulation. They also point to the urgent need for further studies addressing the exciting but difficult issue of cerebral blood flow autoregulation in the neonate.

    Full Text Available Las enfermedades vasculares constituyen las terceras causas de muerte en Cuba. Su variante isquémica es causa de invalidez y perdida de la calidad de la vida. La búsqueda de agentes neuroprotectores es muy importante sí tenemos en cuenta que nuestra población está envejecida. Muchos son las razones por la que una molécula con propiedades neuroprotectoras en los modelos animales no tenga los resultados en ensayos clínicos en humanos. Este trabajo analiza y discute como mejorar estos aspectos. La Eritropoyetina humana recombinante (rHu EPO, conocido por su papel en la diferenciación del eritrocito, ha mostrado ser neuroprotector durante la isquemia cerebral en los modelos de animales adultos. De esta molécula se exponen los mecanismos de acción, que son las bases de los resultados positivos alcanzaron en las investigaciones preclínicas y los ensayos clínicos, que lo proponen como el neuroprotector ideal. Finalmente se comparan los resultados alcanzados por los autores en las investigaciones con la rHu EPO producida por el Centro Molecular de Inmunología de Cuba (CIM. El efecto de la aplicación de rHu EPO se evidenció por la disminución del edema cerebral, preservación de la conducta exploratoria y la disminución de la incidencia de señales clínicas de infarto cerebral y alteraciones patológicas. El grupo de resultados demostró las diferencias significantes entre los animales controles y tratados con el rHu EPO con los no tratados que sugieren que el rHu EPO debe ser considerado como una alternativa terapéutica contra el infarto cerebral en su fase aguda.

    Full Text Available Abstract Valvular strands, well-delineated filiform masses, attached to cardiac valve edges are associated with cerebral embolism and stroke. Strokes, caused by emboli from valvular strands, tend to occur among younger persons. In this case report a valvular strand, giving a peculiar serpentine appearance to the mitral valve is described. This mitral valvular strand was the only explanation for an episode of cerebral embolism, presenting with a transient right sided hemiparesis. It is proposed that a randomized study involving combined treatment with aspirin and clopidogrel is warranted in young patients with valvular strands, presenting with a first episode of cerebral embolism.

    Cerebral edema plays a central role in the pathophysiology of many diseases of the central nervous system (CNS) including ischemia, trauma, tumors, inflammation, and metabolic disturbances. The formation of cerebral edema results in an increase in tissue water content and brain swelling which, if unchecked, can lead to elevated intracranial pressure (ICP), reduced cerebral blood flow, and ultimately cerebral herniation and death. Despite the clinical significance of cerebral edema, the mechan...

    2016-12-01

    We characterised the causative agents of cerebral and non-cerebral coenurosis in livestock by determining the mitochondrial genotypes and morphological phenotypes of 52 Taenia multiceps isolates from a wide geographical range in Europe, Africa, and western Asia. Three studies were conducted: (1) a morphological comparison of the rostellar hooks of cerebral and non-cerebral cysts of sheep and goats, (2) a morphological comparison of adult worms experimentally produced in dogs, and (3) a molecular analysis of three partial mitochondrial genes (nad1, cox1, and 12S rRNA) of the same isolates. No significant morphological or genetic differences were associated with the species of the intermediate host. Adult parasites originating from cerebral and non-cerebral cysts differed morphologically, e.g. the shape of the small hooks and the distribution of the testes in the mature proglottids. The phylogenetic analysis of the mitochondrial haplotypes produced three distinct clusters: one cluster including both cerebral isolates from Greece and non-cerebral isolates from tropical and subtropical countries, and two clusters including cerebral isolates from Greece. The majority of the non-cerebral specimens clustered together but did not form a monophyletic group. No monophyletic groups were observed based on geography, although specimens from the same region tended to cluster. The clustering indicates high intraspecific diversity. The phylogenetic analysis suggests that all variants of T. multiceps can cause cerebral coenurosis in sheep (which may be the ancestral phenotype), and some variants, predominantly from one genetic cluster, acquired the additional capacity to produce non-cerebral forms in goats and more rarely in sheep.

    Full Text Available Astroblastoma is a rare glial neoplasm whose histogenesis has been clarified recently. It primarily occurs in children and young adults. We are reporting a case of 12-year-old girl child who presented with features of raised intracranial tension and generalized tonic-clonic seizures. Brain magnetic resonance imaging revealed a large well-circumscribed, cystic lesion without perifocal edema, and enhancing mural nodule in right parietal region. A radiological differential diagnosis of pilocytic astrocytoma and cerebral astroblastoma was made. A complete excision was done and histologically the lesion turned out to be an astroblastoma. We review the histology, immunohistochemistry, and imaging features of astroblastoma and survey the current literature, treatment strategies, and prognostic aspects for the management of this rare neoplasm.

    1993-01-01

    The inherited forms of craniosynostosis can be divided into 4 groups: isolated craniosynostosis, craniosynostosis with syndactyly, craniosynostosis with polydactyly and syndactyly, and craniosynostosis with other somatic abnormalities. Acrocephalopolysyndactyly or Carpenter syndrome consists of craniosynostosis, short fingers, soft tissue syndactyly, preaxial polydactyly, congenital heart disease, hypogenitalism, obesity, and umbilical hernia. As many as three-fourths of the patients have some degree of intellectual impairment. The etiology of mental retardation in this syndrome has not been explored. A patient is reported with the features of Carpenter syndrome who has profound developmental delay and cerebral malformations demonstrated by magnetic resonance imaging and computed tomography. Because mental retardation is not an invariable feature of this syndrome or other craniosynostosis syndromes, neuroradiologic examination may help in predicting the intellectual outcome in these patients.

    Full Text Available Background/Aim. Cerebral palsy (CP is one of the leading causes of neurological impairment in childhood. Preterm birth is a significant risk factor in the occurrence of CP. Clinical outcomes may include impairment of gross motor function and intellectual abilities, visual impairment and epilepsy. The aim of this study was to examine the relationships among gestational age, type of CP, functional ability and associated conditions. Methods. The sample size was 206 children with CP. The data were obtained from medical records and included gestational age at birth, clinical characteristics of CP and associated conditions. Clinical CP type was determined according to Surveillance of Cerebral Palsy in Europe (SCPE and topographically. Gross motor function abilities were evaluated according to the Gross Motor Function Classification System (GMFCS. Results. More than half of the children with CP were born prematurely (54.4%. Statistically significant difference was noted with respect to the distribution of various clinical types of CP in relation to gestational age (p < 0.001. In the group with spastic bilateral CP type, there is a greater proportion of children born preterm. Statistically significant difference was noted in the functional classification based on GMFCS in terms of gestational age (p = 0.049, children born at earlier gestational age are classified at a higher GMFCS level of functional limitation. The greatest percentage of children (70.0% affected by two or more associated conditions was found in the group that had extremely preterm birth, and that number declined with increasing maturity at birth. Epilepsy was more prevalent in children born at greater gestational age, and this difference in distribution was statistically significant (p = 0.032. Conclusion. The application of antenatal and postnatal protection of preterm children should be a significant component of the CP prevention strategy. [Projekat Ministarstva nauke Republike

    Cortical reorganization has an important role in the recovery of stroke. We analyzed the compensatory cerebral and cerebellar perfusion change in patients with unilateral cerebral infarction using statistical parametric mapping (SPM). Fifty seven {sup 99m}Tc-Ethylene Cystein Diethylester (ECD) cerebral perfusion SPECT images of 57 patients (male/female=38/19, mean age=56{+-}17 years) with unilateral cerebral infarction were evaluated retrospectively. Patients were divided into subgroups according to the location (left, right) and the onset (acute, chronic) of infarction. Each subgroup was compared with normal controls (male/female=11/1, mean age =36{+-}10 years) in a voxel-by-voxel manner (two sample t-test, p<0.001) using SPM. All 4 subgroups showed hyperperfusion in the ipsilateral cerebral cortex, but not in the contralateral cerebral cortex. Chronic left and right infarction groups revealed hyperperfusion in the ipsilateral primary sensorimotor cortex, meanwhile, acute subgroups did not. Contralateral cerebellar hyperperfusion was also demonstrated in the chronic left infarction group. Using {sup 99m}Tc-ECD SPECT, we observed ipsilateral cerebral and contralateral cerebeller hyperperfusion in patients with cerebral infarction. However, whether these findings are related to the recovery of cerebral functions should be further evaluated.

    The purpose of this study was to determine the relationship between cerebral tissue oxygen saturation and cerebral blood volume in patients with traumatic brain injury. Perfusion computed tomography of the brain was performed in 25 patients with traumatic brain injury together with simultaneous SctO2 level measurement using cerebral near-infrared oxymetry. The mean age of the injured persons was 34.5±15.6 years (range 15-65); 14 men, 11 women. The Injury Severity Score (ISS) values were 44.4±9.7 (range 25-81). The Glasgow Coma Score (GCS) mean value before the study was 10.6±2.1 (range 5-13). SctO2 ranged from 51 to 89%, mean 62±8.2%. Cerebral blood volume (CBV) values were 2.1±0.67 ml/100 g (min 1.1; max 4.3 ml/100 g). Cerebral blood flow (CBF) was 31.99±13.6 ml/100 g×min. Mean transit time (MTT) values were 5.7±4.5 s (min 2.8; max 34.3 s). The time to peak (TTP) was 22.2±3.1 s. A statistically significant correlation was found between SctO2 level and cerebral blood volume (CBV) level (R=0.9; pperfusion.

  18. Cerebral malaria: gamma-interferon redux

    Directory of Open Access Journals (Sweden)

    Nicholas H Hunt

    2014-08-01

    Full Text Available There are two theories that seek to explain the pathogenesis of cerebral malaria, the mechanical obstruction hypothesis and the immunopathology hypothesis. Evidence consistent with both ideas has accumulated from studies of the human disease and experimental models. Thus some combination of these concepts seems necessary to explain the very complex pattern of changes seen in cerebral malaria. The interactions between malaria parasites, erythrocytes, the cerebral microvascular endothelium, brain parenchymal cells, platelets and microparticles need to be considered. One factor that seems able to knit together much of this complexity is the cytokine interferon-gamma. In this review we consider findings from the clinical disease, in vitro models and the murine counterpart of human cerebral malaria in order to evaluate the roles played by interferon-gamma in the pathogenesis of this often fatal and debilitating condition.

    Full Text Available Cerebral small vessel disease refers to a group of pathological processes with various etiologies that affect small arteries, arterioles, venules, and capillaries of the brain. Recently, the researches of cerebral small vessel disease have got initial progressions, and a definite diagnosis of this disease is comfirmed by biopsy. Given the pathological material is difficult to obtain, clinicians should pay more attention to the imaging features and clinical manifestations. Correct understanding of imaging and clinical manifestations contributes to the early identification of cerebral small vessel disease. Herein, an overview is provided on the present status, common imaging features, pathogenesis, clinical manifestations and treatment of cerebral small vessel disease. DOI: 10.3969/j.issn.1672-6731.2015.02.003

    Ahmed, Ejaz; Donovan, Tucker; Yujiao, Lu; Zhang, Quanguang

    There has been much evidence suggesting that reactive oxygen species (ROS) generated in mitochondria during cerebral ischemia play a major role in programming the senescence of organism. Antioxidants dealing with mitochondria slow down the appearance and progression of symptoms in cerebral ischemia and increase the life span of organisms. The mechanisms of mitochondrial targeted antioxidants, such as SKQ1, Coenzyme Q10, MitoQ, and Methylene blue, include increasing adenosine triphosphate (ATP) production, decreasing production of ROS and increasing antioxidant defenses, providing benefits in neuroprotection following cerebral ischemia. A number of studies have shown the neuroprotective role of these mitochondrial targeted antioxidants in cerebral ischemia. Here in this short review we have compiled the literature supporting consequences of mitochondrial dysfunction, and the protective role of mitochondrial targeted antioxidants.

Functional neuroimaging studies in support of the concept of CCD has been critically reviewed.

  6. Cerebral microcirculation during experimental normovolaemic anaemia

    2016-02-01

    Full Text Available Anaemia is accepted amongst critically ill patients as an alternative to elective blood transfusion. This practice has been extrapolated to head injury patients with only one study comparing the effects of mild anaemia on neurological outcome. There are no studies quantifying microcirculation during anaemia. Experimental studies suggest that anaemia leads to cerebral hypoxia and increased rates of infarction, but the lack of clinical equipoise when testing the cerebral effects of transfusion amongst critically injured patients, supports the need of experimental studies. The aim of this study was to quantify cerebral microcirculation and the potential presence of axonal damage in an experimental model exposed to normovolaemic anaemia, with the intention of describing possible limitations within management practices in critically ill patients. Under non-recovered anaesthesia, six Merino sheep were instrumented using an intracardiac transeptal catheter to inject coded microspheres into the left atrium to ensure systemic and non-chaotic distribution. Cytometric analyses quantified cerebral microcirculation at specific regions of the brain. Amyloid precursor protein staining was used as an indicator of axonal damage. Animals were exposed to normovolaemic anaemia by blood extractions from the indwelling arterial catheter with simultaneous fluid replacement through a venous central catheter. Simultaneous data recording from cerebral tissue oxygenation, intracranial pressure and cardiac output was monitored. A regression model was used to examine the effects of anaemia on microcirculation with a mixed model to control for repeated measures. Homogeneous and normal cerebral microcirculation with no evidence of axonal damage was present in all cerebral regions, with no temporal variability, concluding that acute normovolaemic anaemia does not result in short term effects on cerebral microcirculation in the ovine brain.

    2016-03-01

    Cerebral oximeters measure continuous cerebral oxygen saturation using near-infrared spectroscopy (NIRS) technology noninvasively. It has been involved into operating room setting to monitor oxygenation within patient's brain when surgeons are concerned that a patient's levels might drop. Recently, cerebral oxygen saturation has also been related with chronic cerebral vascular insufficiency (CCVI). Patients with CCVI would be benefited if there would be a wearable system to measure their cerebral oxygen saturation in need. However, there has yet to be a wearable wireless cerebral oximeter to measure the saturation in 24 hours. So we proposed to develop the wearable wireless cerebral oximeter. The mechanism of the system follows the NIRS technology. Emitted light at wavelengths of 740nm and 860nm are sent from the light source penetrating the skull and cerebrum, and the light detector(s) receives the light not absorbed during the light pathway through the skull and cerebrum. The amount of oxygen absorbed within the brain is the difference between the amount of light sent out and received by the probe, which can be used to calculate the percentage of oxygen saturation. In the system, it has one source and four detectors. The source, located in the middle of forehead, can emit two near infrared light, 740nm and 860nm. Two detectors are arranged in one side in 2 centimeters and 3 centimeters from the source. Their measurements are used to calculate the saturation in the cerebral cortex. The system has included the rechargeable lithium battery and Bluetooth smart wireless micro-computer unit.

    Purpose: The purpose of our study is to evaluate the efficacy of cerebral perfusion single photon emission computerized tomography (SPECT) in patients with transient ischemic attack (TIA). Methods: Thirty-seven patients with TIA were collected for study. All patients had transient focal neurological symptoms or signs with complete recovery within 24 h after onset. The patients underwent cerebral perfusion SPECT between 6 h and 11 days after onset, with 10 cases performed within 24 h (group A), nine cases performed between 1 and 3 days (group B), 11 cases performed between 3 and 5 days (group C), and seven cases performed after more than 5 days (group D). A semi-quantitative method was used for analyzing the SPECT data, and the difference ratios between lesion side and contralateral normal side were calculated on each pair of regions of interest. Results: In total, 78.4% (29/37) of patients had reduced perfusion in the cerebral cortical regions or deep nuclei, and the regions with reduced perfusion corresponded with clinical presentations of the patients. The abnormal rate with reduced perfusion was 90.0% in group A, 77.8% in group B, 72.7% in group C and 71.4% in group D. Cross cerebellar diaschisis (CCD) was present in seven patients, and all of the primary cerebral perfusion defects of these patients were located at the territory of left or right middle cerebral artery. Conclusion: Cerebral perfusion SPECT is a potential tool to detect cerebral perfusion defects and CCD in patients with TIA. Although the perfusion defect may persist more than 5 days after onset, we suggest cerebral perfusion SPECT should be performed as soon as possible.

Results. In ischemic stroke, hyperuricemia reflects the severity of cerebral metabolic disturbances, hemodynamic instability, hypercoagulation susceptiility, and the extent of neurological deficit. In ischemic stroke, hyperuri-corachia is accompanied by the higher spinal fluid levels of adenine, guanine, hypoxanthine, and xanthine and it is an indirect indicator of respiratory disorders of central genesis, systemic acidosis, hypercoagulation susceptibility, free radical oxidation activation, the intensity of a stressor response to cerebral ischemia, cerebral metabolic disturbances, the depth of reduced consciousness, and the severity of neurological deficit. Conclusion. The high venous blood activity of xanthine oxidase in ischemic stroke is associated with the better neurological parameters in all follow-up periods, the better early functional outcome, and lower mortality rates. Key words: hyperuricemia, stroke, xanthine oxidase, uric acid, cerebral ischemia.

    Cerebral vasospasm associated with hyperthyroidism has not been reported to cause cerebral infarction. The case reported here is therefore the first of cerebral infarction co-existing with severe vasospasm and hyperthyroidism. A 30-year-old woman was transferred to our hospital in a stuporous state with right hemiparesis. At first, she complained of headache and dizziness. However, she had no neurological deficits or radiological abnormalities. She was diagnosed with hyperthyroidism 2 months ago, but she had discontinued the antithyroid medication herself three days ago. Magnetic resonance imaging and angiography showed cerebral infarction with severe vasospasm. Thus, chemical angioplasty using verapamil was performed two times, and antithyroid medication was administered. Follow-up angiography performed at 6 weeks demonstrated complete recovery of the vasospasm. At the 2-year clinical follow-up, she was alert with mild weakness and cortical blindness. Hyperthyroidism may influence cerebral vascular hemodynamics. Therefore, a sudden increase in the thyroid hormone levels in the clinical setting should be avoided to prevent cerebrovascular accidents. When neurological deterioration is noticed without primary cerebral parenchyma lesions, evaluation of thyroid function may be required before the symptoms occur. PMID:28184350

    BACKGROUND: Several studies have demonstrated that sustained cognitive tasks can induce cognitive fatigue and that the mean cerebral blood flow velocity changes in some cerebral regions during cerebral fatigue. OBJECTIVE: To dynamically monitor the changes in mean cerebral blood flow velocity in different brain regions of high performance fighter pilots during mental arithmetic tasks and consecutive performance tasks. DESIGN, TIME AND SETTING: The present neurophysiological trial, based on controlled observation, was performed at the Laboratory of Neurophysiology, Institute of Aviation Medicine, Air Force of China between January 2003 and December 2005. PARTICIPANTS: Forty-five males, high performance fighter pilots, averaging (27.6 ± 2.5) years, were recruited for this study. METHODS: The mean cerebral blood flow velocity in the anterior cerebral artery, middle cerebral artery, and posterior cerebral artery of subjects was dynamically tested using transcranial Doppler during 5- hour mental arithmetic tasks and during 5- hour consecutive performance tasks. The neurobehavioral ability index was analyzed throughout each trial according to the number of correct responses, false responses, and lost responses. Simultaneously, cerebral cognitive fatigue-induced lethargy was assessed by the Stanford Sleepiness Scale. MAIN OUTCOME MEASURES: Changes in mean cerebral blood flow velocity in the anterior cerebral artery, middle cerebral artery, and posterior cerebral artery; neurobehavioral ability index of mental arithmetic and consecutive performance tasks; Stanford Sleepiness Scale scores. RESULTS: During mental arithmetic tasks, the mean cerebral blood flow velocity in the anterior cerebral artery increased during hour 2 and decreased after hour 4. There was no significant change in mean cerebral blood flow velocity in the middle cerebral artery and posterior cerebral artery. During hour 4, cerebral cognitive fatigue was observed and, simultaneously, Stanford Sleepiness

  1. TRANSEXUALIDAD: UNA ALTERACIÓN CEREBRAL QUE COMIENZA A CONOCERSE

    Directory of Open Access Journals (Sweden)

    NATALIA LÓPEZ MORATALLA

    2016-01-01

    Full Text Available La transexualidad describe la condición de una persona cuyo sexo psicológico difiere del biológico. Las personas con trastorno de identidad de género sufren de forma persistente por esta incongruencia y buscan un cambio de la anatomía sexual, mediante tratamiento hormonal y quirúrgico. Esta revisión, desde una perspectiva ética, ofrece una visión de las correlaciones neurobiológicas estructurales y funcionales de la transexualidad y los procesos de cambio cerebrales por la administración de las hormonas del sexo deseado. Varios estudios demuestran un aumento de la conectividad funcional entre regiones de la corteza cerebral, que son huellas de la angustia psicosocial generada por la discordancia entre el sexo psicológico y el biológico. Tal angustia se puede atribuir a una imagen corporal incongruente debida a los cambios en la conectividad funcional de los componentes clave de la red de representación del cuerpo. Parte de los cambios de la conectividad suponen un mecanismo de defensa puesto que disocia la emoción sentida de la imagen corporal. Las personas transexuales presentan signos de feminización o masculinización de estructuras y procesos cerebrales con dimorfismo sexual y que durante la administración hormonal se desplazan parcialmente aún más hacia las correspondientes al sexo deseado. Estos cambios permiten una reducción de la angustia psicosocial. Sin embargo, un modelo de “reasignación del sexo” no resuelve el problema, puesto que no se trata la alteración cerebral que lo causa. Se trata de una grave cuestión de ética médica. La liberación de los prejuicios para conocer lo que ocurre en el cerebro de los transexuales es una necesidad médica, tanto para definir lo que es y no es un tratamiento terapéutico, como para guiar las acciones legales.

    Introducción: la esclerosis sistémica (ES) es una enfermedad autoinmune, sistémica, caracterizada por fibrosis, alteraciones inmunológicas y vasculares. La hipoperfusión cerebral puede ser causada por isquemia. Los trastornos cognitivos son causa importante de morbilidad. El objetivo de este estudio fue determinar la frecuencia de alteraciones en la perfusión cerebral (PC) en pacientes con ES y deterioro cognitivo (DC). Métodos: se estudiaron 88 pacientes con ES. A todos se les aplicó el Test de Montreal (TM) para evaluar el DC. A 15 pacientes con DC que cumplieron con los criterios (sin hipertensión arterial sistémica, diabetes mellitus, evento vascular cerebral, vasculitis, hipotiroidismo, depresión, sin ingesta de fármacos que interfieran con la evaluación cognitiva), se les midió la PC mediante Gamagrama Cerebral Perfusorio (GCP).Resultados: de los 88 pacientes con ES, 58 tuvieron DC con el TM. La PC se encontró disminuida en 12/15. La disminución de la PC se observó en los siguientes lóbulos (frontal en 9/15; temporal en 7/15, y parietal en 3/15. La concordancia entre el TM y GC fue 60 % para el lóbulo frontal, 46 % para el lóbulo temporal y 13 % parietal.Conclusiones: el DC es frecuente en la ES, la disminución de la PC fue más común en el lóbulo frontal, predominado en los pacientes de mayor edad y tiempo de evolución de la ES.

    Objective To investigate pre- and postoperative changes of regional cerebral cortical blood flow in patients with cerebral arteriovenous malformation. Method Twenty-two adult patients with arteriovenous malformation(AVM) were recruited into this study at Beijing Tiantan Hospital from September 2001 to May 2002. Eight patients had giant cerebral AVM and the other 14 had a small one. Cortical cerebral blood flow (CBF) was measured by laser Doppler flowmetry (LDF) before and after AVM resections. After surgery, the probe of LDF was implanted adjacent to the area of AVM and monitored for 24 hours.Results CBF increased significantly after the resection in all patients regardless of AVM size. In patients with small AVM, CBF returned to the baseline level within 4 hours, but in patients with giant AVM, CBF remained high even after 24 hours.Conclusions Monitoring CBF is helpful to understand pre- and postoperative changes of regional cortical CBF in patients with cerebral AVM.

    Necrotizing fasciitis is a soft tissue infection that is characterized by extensive necrosis of the subcutaneous fat, neurovascular structures, and fascia. Cerebral infarction after facial necrotizing fasciitis has been rarely reported. A 61-year-old woman with diabetes was admitted with painful swelling of her right cheek. One day later, she was stuporous and quadriplegic. A computed tomographic scan of her face revealed right facial infection in the periorbital soft tissue, parotid, buccal muscle, and maxillary sinusitis. A computed tomographic scan of the brain revealed cerebral infarction in the right hemisphere, left frontal area, and both cerebellum. Four days later, she died from cerebral edema and septic shock. Involvement of the cerebral vasculature, such as the carotid or vertebral artery by necrotizing fasciitis, can cause cerebral infarction. Facial necrotizing fasciitis should be treated early with surgical treatment and the appropriate antibiotic therapy.

  18. The effect of herbs on cerebral energy metabolism in cerebral ischemia-reperfusion mice

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    @@Vascular dementia is one of the most familiar types of senile dementia. Over the past few years, the research on the damage of cerebral tissues after ischemia has become a focus. The factors and mechanism of cerebral tissue damage after ischemia are very complex. The handicap of energy metabolism is regarded as the beginning factor which leads to the damage of neurons, but its dynamic changes in ischemic area and its role during the process of neuronal damage are not very clear. There are few civil reports on using 31 P nuclear magnetic resonance instrument to explore the changes of cerebral energy metabolism in intravital animals. After exploring the influence of herbs on cerebral energy metabolism in ischemia-reperfusion mice, we came to the conclusion that herbs can improve the cerebral energy metabolism in ischemia-reperfusion mice.

  19. Cerebral CT of ischaemic lesions

    Aulich, A.

    1981-11-25

    The diagnosis of stroke must first be established by clinical examination. CT has proved useful for confirmation of the diagnosis and provides a global intracranial picture of morphological changes in cerebral vascular diseases. A hemorrhage can be recognized with certainty at the first CT examination as the cause of the stroke, but in the detection of a lesion due to ischemia an important role is played by the correct choice of the time of examination, and in some cases also of the check-up with contrast medium. The differential diagnosis between infarct in the acute stage and encephalitis or gliomas of low-grade malignity can be difficult. A decision can often only be made after a series of examinations. Postmalacial conditions are often difficult to differentiate from defects due to other causes, such as hemorrhage, head injury, postoperative states and after encephalitis. A knowledge of the anamnesis and the clinical findings is indispensable for CT evaluation. In assessing the prognosis before vascular surgery on the extracranial brain-supplying vessels the performance of a CT examination should be advised. A warning is given against the use of CT as a screening method.

    Presentation of a cerebral aneurysm can be incidental, discovered at imaging obtained for unrelated causes, can occur in the occasion of imaging obtained for symptoms possibly or likely related to the presence of an unruptured aneurysm, or can occur with signs and symptoms at the time of aneurismal rupture. Most unruptured intracranial aneurysms are thought to be asymptomatic, or present with vague or non-specific symptoms like headache or dizziness. Isolated oculomotor nerve palsies, however, may typically indicate the presence of a posterior circulation aneurysm. Ruptured intracranial aneurysms are by far the most common cause of non-traumatic subarachnoid hemorrhage and represent a neurological emergency with potentially devastating consequences. Subarachnoid hemorrhage may be easily suspected in the presence of sudden and severe headache, vomiting, meningism signs, and/or altered mental status. However, failure to recognize milder and more ambiguous clinical pictures may result in a delayed or missed diagnosis. In this paper we will describe the clinical spectrum of unruptured and ruptured intracranial aneurysms by discussing both typical and uncommon clinical features emerging from the literature review. We will additionally provide the reader with descriptions of the underlying pathophysiologic mechanisms, and main diagnostic pitfalls.

    Cerebral palsy is the most prevalent cause of persisting motor function impairment with a frequency of about 1/500 births. In developed countries, the prevalence rose after introduction of neonatal intensive care, but in the past decade, this trend has reversed. A recent international workshop defined cerebral palsy as "a group of permanent disorders of the development of movement and posture, causing activity limitation, that are attributed to non-progressive disturbances that occurred in the developing fetal or infant brain." In a majority of cases, the predominant motor abnormality is spasticity; other forms of cerebral palsy include dyskinetic (dystonia or choreo-athetosis) and ataxic cerebral palsy. In preterm infants, about one-half of the cases have neuroimaging abnormalities, such as echolucency in the periventricular white matter or ventricular enlargement on cranial ultrasound. Among children born at or near term, about two-thirds have neuroimaging abnormalities, including focal infarction, brain malformations, and periventricular leukomalacia. In addition to the motor impairment, individuals with cerebral palsy may have sensory impairments, cognitive impairment, and epilepsy. Ambulation status, intelligence quotient, quality of speech, and hand function together are predictive of employment status. Mortality risk increases incrementally with increasing number of impairments, including intellectual, limb function, hearing, and vision. The care of individuals with cerebral palsy should include the provision of a primary care medical home for care coordination and support; diagnostic evaluations to identify brain abnormalities, severity of neurologic and functional abnormalities, and associated impairments; management of spasticity; and care for associated problems such as nutritional deficiencies, pain, dental care, bowel and bladder continence, and orthopedic complications. Current strategies to decrease the risk of cerebral palsy include interventions to

  7. Cerebral Tissue Oxygenation during Immediate Neonatal Transition and Resuscitation

    This article provides a review of cerebral tissue oxygenation during immediate transition after birth in human neonates. Recommended routine monitoring, especially if resuscitation is needed, during this period includes arterial oxygen saturation and heart rate measured by pulse oximetry and electrocardiogram. However, there is increasing interest to monitor in addition with near-infrared spectroscopy (NIRS) the oxygenation of the brain. There is a different pattern of increase between cerebral tissue oxygenation and arterial oxygen saturation during the immediate transition, with cerebral tissue oxygenation reaching a plateau faster than arterial oxygen saturation. Differences can be explained, since cerebral tissue oxygenation is not only affected by arterial oxygen saturation but also by cerebral blood flow, hemoglobin content, and cerebral oxygen consumption. Normal values have already been established for different devices, gestational ages, and modes of delivery in neonates without any medical support. Cerebral hypoxia during immediate transition might cause brain damage. In preterm neonates with cerebral hemorrhage evolving in the first week after birth, the cerebral tissue oxygenation is already lower in the first minutes after birth compared to preterm neonates without cerebral hemorrhage. Using cerebral NIRS in combination with intervention guidelines has been shown to reduce the burden of cerebral hypoxia in preterm neonates. Cerebral tissue oxygenation during immediate transition seems to have an impact on outcome, whereby NIRS monitoring is feasible and has the advantage of continuous, non-invasive recording. The impact of NIRS monitoring and interventions on short- and long-term outcomes still need to be evaluated. PMID:28280719

    Full Text Available In non-missile severe acute brain trauma, brain ischemia was a frequent finding in cadavers. Studies during neuro intensive care, however, have failed to disclose brain ischemia under most circumstances, except when cerebral hemodynamic and metabolic parameters have been misinterpreted, or when cerebral blood flow (CBF alone has been addressed in a biased fashion, without mandatory metabolic data. Indeed, comprehensive and unbiased studies focusing on global cerebral metabolic activity have invariably revealed a condition of normal coupling between reduced CBF and oxygen consumption in the early postinjury hours, which is then followed by a prolonged, sustained pattern of relative cerebral hyperperfusion (the opposite of ischemia. Accordingly, traumatic brain ischemia during intensive care represents myth rather than fact.Em traumatismo cerebral agudo grave excluindo-se ferimentos por arma de fogo, isquemia cerebral foi achado frequente em cadáveres. Entretanto, estudos durante neuro terapia intensiva não têm revelado isquemia cerebral, exceto quando parâmetros hemodinâmicos e metabólicos cerebrais tem sido mal interpretados, ou quando fluxo sanguíneo cerebral (FSC sozinho tem sido enfocado de forma tendenciosa, sem dados metabólicos mandatórios.

Assim sendo, isquemia cerebral traumática durante terapia intensiva representa um mito ao invés de um fato.

  11. Time-varying modeling of cerebral hemodynamics.

    2014-03-01

    The scientific and clinical importance of cerebral hemodynamics has generated considerable interest in their quantitative understanding via computational modeling. In particular, two aspects of cerebral hemodynamics, cerebral flow autoregulation (CFA) and CO2 vasomotor reactivity (CVR), have attracted much attention because they are implicated in many important clinical conditions and pathologies (orthostatic intolerance, syncope, hypertension, stroke, vascular dementia, mild cognitive impairment, Alzheimer's disease, and other neurodegenerative diseases with cerebrovascular components). Both CFA and CVR are dynamic physiological processes by which cerebral blood flow is regulated in response to fluctuations in cerebral perfusion pressure and blood CO2 tension. Several modeling studies to date have analyzed beat-to-beat hemodynamic data in order to advance our quantitative understanding of CFA-CVR dynamics. A confounding factor in these studies is the fact that the dynamics of the CFA-CVR processes appear to vary with time (i.e., changes in cerebrovascular characteristics) due to neural, endocrine, and metabolic effects. This paper seeks to address this issue by tracking the changes in linear time-invariant models obtained from short successive segments of data from ten healthy human subjects. The results suggest that systemic variations exist but have stationary statistics and, therefore, the use of time-invariant modeling yields "time-averaged models" of physiological and clinical utility.

    The aim of this study was to determine the effects of desflurane, at 1 and 1.5 MAC, on cerebral autoregulation. Data were analysed from eight patients undergoing non-neurosurgical procedure. The blood flow velocity in the middle cerebral artery was measured by transcranial Doppler ultrasound and cerebral autoregulation was assessed by the transient hyperaemic response test. Partial pressure of the end-tidal carbon dioxide (PE'(CO(2))) and mean arterial pressure were measured throughout the study. Anaesthesia was induced with propofol and was maintained with desflurane at end-tidal concentrations of 7.4% (1 MAC) or 10.8% (1.5 MAC). The order of administration of the desflurane concentrations was determined randomly and a period of 15 min was allowed for equilibration at each concentration. The transient hyperaemic response tests were performed before induction of anaesthesia and after equilibration with each concentration of desflurane. An infusion of phenylephrine was used to maintain pre-induction mean arterial pressure and ventilation was adjusted to maintain the pre-induction value of PE'(CO(2)) throughout the study. Two indices derived from the transient hyperaemic response test (the transient hyperaemic response ratio and the strength of autoregulation) were used to assess cerebral autoregulation. Desflurane resulted in a marked and significant impairment in cerebral autoregulation; at concentrations of 1.5 MAC, autoregulation was almost abolished.

    Progressive supranuclear palsy (PSP) is a Parkinson-plus syndrome characterized clinically by supranuclear ophthalmoplegia, pseudobulbar palsy, axial rigidity, bradykinesia, postural instability and dementia. Presence of dementia and lack of cortical histopathology suggest the derangement of cortical function by pathological changes in subcortical structures in PSP, which is supported by the pattern of behavioral changes and measurement of brain metabolism using positron emission tomography. This study was done to examine whether there are specific changes of regional cerebral perfusion in PSP and whether there is a correlation between severity of motor abnormaility and degree of changes in cerebral perfusion. We measured regional cerebral perfusion indices in 5 cortical and 2 subcortical areas in 6 patients with a clinical diagnosis of PSP and 6 healthy age and sex matched controls using Tc-99m-HMPAO SPECT. Compared with age and sex matched controls, only superior frontal regional perfusion index was significantly decreased in PSP (p<0.05). There was no correlation between the severity of the motor abnormality and any of the regional cerebral perfusion indices (p>0.05). We affirm the previous reports that perfusion in superior frontal cortex is decreased in PSP. Based on our results that there was no correlation between severity of motor abnormality and cerebral perfusion in the superior frontal cortex, nonmotoric symptoms including dementia needs to be looked at whether there is a correlation with the perfusion abnormality in superior frontal cortex

    Carotid angioplasty with stenting is a reliable method of primary and secondary prevention of ischaemic stroke in patients with stenosing lesions of the internal carotid artery. However, carrying out such operations is sometimes associated with risk for the development of intraoperative impairments of cerebral circulation due to arterioarterial embolism in cerebral arteries, as well as vasospasm. Presented herein are the results of following up a total of 64 patients with pronounced atherosclerotic lesions of internal carotid arteries (>70%) - "symptomatic" and "asymptomatic", undergoing carotid stenting. Acute foci of ischaemia in the brain after stenting according to the findings of diffusion-weighted magnetic resonance tomography were revealed in 40% of cases, and in only 6% of patients they manifested themselves by symptoms of acute cerebral circulatory impairment. We revealed a direct correlation between the number, size of infarctions in the brain, and the appearance of neurological symptomatology. Intraoperative monitoring of blood flow in the middle cerebral artery during stenting makes it possible to predict the appearance of acute foci of cerebral ischaemia, to specify the genesis of perioperative stroke, as well as to evaluate clinical significance of vasospasm and material microembolism. The obtained findings should concentrate neurologists' attention on active postoperative follow up of patients subjected to carotid angioplasty with stenting in order to perform adequate personified neuroprotective correction, including preventive one.

    Full Text Available Background. Nontraumatic cerebral air embolism cases are rare. We report a case of an air embolism resulting in cerebral infarction related to angioinvasive cavitary aspergillosis. To our knowledge, there have been no previous reports associating these two conditions together. Case Presentation. A 32-year-old female was admitted for treatment of acute lymphoblastic leukemia (ALL. Her hospital course was complicated by pulmonary aspergillosis. On hospital day 55, she acutely developed severe global aphasia with right hemiplegia. A CT and CT-angiogram of her head and neck were obtained demonstrating intravascular air emboli within the left middle cerebral artery (MCA branches. She was emergently taken for hyperbaric oxygen therapy (HBOT. Evaluation for origin of the air embolus revealed an air focus along the left lower pulmonary vein. Over the course of 48 hours, her symptoms significantly improved. Conclusion. This unique case details an immunocompromised patient with pulmonary aspergillosis cavitary lesions that invaded into a pulmonary vein and caused a cerebral air embolism. With cerebral air embolisms, the acute treatment option differs from the typical ischemic stroke pathway and the provider should consider emergent HBOT. This case highlights the importance of considering atypical causes of acute ischemic stroke.

    Cerebral edema formation stems from disruption of blood brain barrier (BBB) integrity and occurs after injury to the CNS. Due to the restrictive skull, relatively small increases in brain volume can translate into impaired tissue perfusion and brain herniation. In excess, cerebral edema can be gravely harmful. Astrocytes are key participants in cerebral edema by virtue of their relationship with the cerebral vasculature, their unique compliment of solute and water transport proteins, and their general role in brain volume homeostasis. Following the discovery of aquaporins, passive conduits of water flow, aquaporin 4 (AQP4) was identified as the predominant astrocyte water channel. Normally, AQP4 is highly enriched at perivascular endfeet, the outermost layer of the BBB, whereas after injury, AQP4 expression disseminates to the entire astrocytic plasmalemma, a phenomenon termed dysregulation. Arguably, the most important role of AQP4 is to rapidly neutralize osmotic gradients generated by ionic transporters. In pathological conditions, AQP4 is believed to be intimately involved in the formation and clearance of cerebral edema. In this review, we discuss aquaporin function and localization in the BBB during health and injury, and we examine post-injury ionic events that modulate AQP4- dependent edema formation.

    Full Text Available La presencia de plomo en el medio ambiente es un hecho indiscutible. Ello es objeto de gran interés sanitario pues repercute tanto en la salud de los animales como en la del ser humano. El plumbismo es una intoxicación que puede afectar a cualquier especie animal. En el ámbito de la fauna silvestre se asocia principalmente a la actividad cinegética en los humedales y a la ingestión de plomo metálico por parte de las aves que frecuentan estos ecosistemas. En España cada año mueren decenas de miles de aves acuáticas como consecuencia de la ingesta de perdigones de plomo. En los individuos capturados enfermos se pueden observar signos clínicos, mientras que a partir de muestras de cadáveres se obtienen datos sobre niveles tisulares de plomo. Sin embargo la evaluación de lesiones anatomopatológicas en animales de vida silvestre es difícil de realizar por la dificultad de encontrar animales recién muertos o afectados de un cuadro agudo mortal. La reproducción de esta patología en animales de experimentación se suele realizar en cisnes, palomas o patos, pero no en flamencos, por lo que no es usual disponer de datos histológicos en esta especie. En este trabajo presentamos la clínica, analítica y estudio microscópico de diferentes tejidos de un flamenco común (Phoenicopterus roseus muerto por plumbismo.

    Cerebral edema is a life-threatening complication of diabetic ketoacidosis (DKA) which may predominantly develop in pediatric cases during the management of DKA.. Symptomatic cerebral edema in children is rarely detected at admission, before initiation of the treatment. Cerebral edema associated with DKA is extremely rare in adults. Here, we report an adult patient with DKA who presented with symptomatic cerebral edema. Turk Jem 2009; 13: 16-8

    Post-ischemic hyperglycemia exacerbates the development of cerebral ischemia. To elucidate this exacerbation mechanism, we focused on sodium-glucose transporter (SGLT) as a mediator that lead hyperglycemia to cerebral ischemia. SGLT transport glucose into the cell, together with sodium ion, using the sodium concentration gradient. We have previously reported that suppression of cerebral SGLT ameliorates cerebral ischemic neuronal damage. However, detail relationship cerebral between SGLT and post-ischemic hyperglycemia remain incompletely defined. Therefore, we examined the involvement of cerebral SGLT on cerebral ischemic neuronal damage with or without hyperglycemic condition. Cell survival rate of primary cultured neurons was assessed by biochemical assay. A mouse model of focal ischemia was generated using a middle cerebral artery occlusion (MCAO). Neuronal damage was assessed with histological and behavioral analyses. Concomitant hydrogen peroxide/glucose treatment exacerbated hydrogen peroxide alone-induced cell death. Although a SGLT family-specific inhibitor, phlorizin had no effect on developed hydrogen peroxide alone-induced cell death, it suppressed cell death induced by concomitant hydrogen peroxide/glucose treatment. α-MG induced a concentration-dependent and significant decrease in neuronal survival. PHZ administered on immediately after reperfusion had no effect, but PHZ given at 6h after reperfusion had an effect. Our in vitro study indicates that SGLT is not involved in neuronal cell death in non-hyperglycemic condition. We have already reported that post-ischemic hyperglycemia begins to develop at 6h after MCAO. Therefore, current our in vivo study show post-ischemic hyperglycemic condition may be necessary for the SGLT-mediated exacerbation of cerebral ischemic neuronal damage.

    Increased natriuresis is a frequent situation after subarachnoid haemorrhage (SAH). It may be responsible for hyponatremia, which can be dangerous in case of severe hypo-osmolarity or hypovolemia. Inappropriate secretion of antidiuretic hormone or cerebral salt wasting syndrome (CSWS) have been incriminated for hyponatremia after SAH, but it remains difficult to distinguish between both syndromes. There are many explanations for increased natriuresis after SAH, depending on the level of blood pressure, the volemia, and the presence or not of natriuretic peptides. The cerebral insult and the treatments, which are done to fight against elevated intracranial pressure or vasospasm, can modify any of these parameters. So it appears that the word "cerebral" in CSWS is probably not a good term and it would be better to talk about appropriate or non-appropriate natriuretic response. Corticoïds or urea can be useful for controlling hypernatriuresis.

    2015-01-01

    Over the last years, a number of patients with chronic cerebral ischemia has been increased significantly. Compensatory possibilities of the brain and cerebral circulatory system are so great that even serious disturbances of blood circulation could not cause clinical signs of brain dysfunction for a long time. At the same time, long-term ischemia can lead to peripheral local disturbances of microcirculation that is appears to be a first signal of the problems with homeostasis. Therefore, Raynaud's syndrome may be one of the predictors of standard symptoms of chronic cerebral ischemia (CCI). This phenomenon is explicitly considered as a sign of blood circulation impairment while the pathogenetic mechanism of vascular arterial bed instability is completely ignored. Detailed study of clinical correlations of Raynaud's syndrome in CCI would help to develop a common pharmacotherapeutic approach to its treatment.

  17. Assessment of the hand in cerebral palsy

    Full Text Available Cerebral palsy is the musculoskeletal manifestation of a nonprogressive central nervous system lesion that usually occurs due to a perinatal insult to the brain. Though the cerebral insult is static the musculoskeletal pathology is progressive. Some patients with cerebral palsy whose hands are affected can be made better by surgery. The surgical procedures as such are not very technically demanding but the assessment, decision-making, and selecting the procedures for the given patient make this field challenging. When done well, the results are rewarding not only in terms of improvement in hand function but also in appearance and personal hygiene, which leads to better self-image and permits better acceptance in the society. This article focuses on the clinical examination, patient selection, and decision-making while managing these patients.

    Renovascular hypertensive rats (RHRs) were developed using the 2-kidney, 2-clip method. All RHRs at 10 weeks displayed high permeability of the cerebral surface blood vessels. Vascular casts of the RHRs showed that the vascular network was sparse. The arterioles of the RHRs at 10 weeks had smaller lumen diameters, but thicker vessel walls with hyalinosis formation compared with control animals. The endothelial cell membrane appeared damaged, and microthrombus formed. After ischemia, the infarction size was larger in RHRs than in control animals. These results suggest that cerebral arterioles in RHRs underwent structural remodeling. High blood pressure may aggravate the severity of brain injury in cerebral ischemia and affect the recovery of ischemia.

    Full Text Available Objective: Cerebral hydatid disease (CHD is a rare manifestation of echinococcosis but it constitutes a significant fraction of all intracranial mass lesions. In this paper we have reported two children with primary CHD without associated extracranial lesions.Case Presentation: Two cases of isolated cerebral hydatid disease are described. They were 7- and 10-year old children referred with focal neurological deficits and intracranial hypertension. Extensive extracranial investigations were negative. The literature concerning isolated cerebral hydatid disease is reviewed, and possible mechanisms by which the disease can be limited to brain, are discussed.Conclusion: Isolated CHD can occur with different mechanisms. Lack of effective immune system in the brain, the special architecture of brain tissue permitting rapid growth of cyst, patent ductus arteriosus, and patent foramen ovale, have been the proposed factors, but none of them has been proved yet.

    2006-01-01

    The method of transcranial electrostimulation (TCES) has been used for treatment of 68 patients with chronic cerebral vascular insufficiency, stages I and II. A treatment course included 7 daily procedures. The influence of TCES was evaluated clinically, by EEG, transcranial ultrasonic Doppler study and hemodynamic indices in arteries and veins as well as by expression of trait and state anxiety. All the parameters were compared to those of the control group which was treated using conventional methods. TCES resulted in normalization of cerebral vascular reactivity, a decrease of venous circulation disturbances, positive influence on cerebral blood flow and EEG parameters, that corresponded to global improvement of the patients' state, regress of cephalgic syndrome and reduction of trait and state anxiety. The method is simple and safety and can be recommended for wide application including outpatient setting.

    An immigrant from Romania was referred to the neurosurgical unit with a cerebral abscess. On examination she was cyanosed and had clubbing of her fingers. A cardiovascular system examination revealed a systolic murmur heard all over the precordium. However, the diagnosis was not congenital cyanotic heart disease. The patient had a history of frequent nosebleeds and had multiple telangiectases on her body, leading to the diagnosis of hereditary haemorrhagic telangiectasia (HHT). A search was carried out for the presence of arteriovenous malformations in internal organs. Large arteriovenous malformations were found in the lungs, causing her cyanosis due to right-to-left shunting of blood and cerebral abscess due to paradoxical septic embolisation into cerebral circulation.

    Background In adult humans, cerebral microbleeds play important roles in neurodegenerative diseases but in neonates, the consequences of cerebral microbleeds are unknown. In rats, a single pro-angiogenic stimulus in utero predisposes to cerebral microbleeds after birth at term, a time when late oligodendrocyte progenitors (pre-oligodendrocytes) dominate in the rat brain. We hypothesized that two independent pro-angiogenic stimuli in utero would be associated with a high likelihood of perinatal microbleeds that would be severely damaging to white matter. Methods Pregnant Wistar rats were subjected to intrauterine ischemia (IUI) and low-dose maternal lipopolysaccharide (mLPS) at embryonic day (E) 19. Pups were born vaginally or abdominally at E21-22. Brains were evaluated for angiogenic markers, microhemorrhages, myelination and axonal development. Neurological function was assessed out to 6 weeks. Results mRNA (Vegf, Cd31, Mmp2, Mmp9, Timp1, Timp2) and protein (CD31, MMP2, MMP9) for angiogenic markers, in situ proteolytic activity, and collagen IV immunoreactivity were altered, consistent with an angiogenic response. Vaginally delivered pups exposed to prenatal IUI+mLPS had spontaneous cerebral microbleeds, abnormal neurological function, and dysmorphic, hypomyelinated white matter and axonopathy. Pups exposed to the same pro-angiogenic stimuli in utero but delivered abdominally had minimal cerebral microbleeds, preserved myelination and axonal development, and neurological function similar to naïve controls. Conclusions In rats, pro-angiogenic stimuli in utero can predispose to vascular fragility and lead to cerebral microbleeds. The study of microbleeds in the neonatal rat brain at full gestation may give insights into the consequences of microbleeds in human preterm infants during critical periods of white matter development.

    Current understanding of cerebral FDG uptake during childhood originates from a small number of studies in patients with neurological abnormalities. Our aim was to describe cerebral FDG uptake in a dataset of FDG PET scans in children more likely to represent a normal population. We reviewed cerebral FDG PET scans in children up to 16 years of age with suspected/proven extracranial malignancies and the following exclusions: central nervous system metastases, previous malignancies, previous chemotherapy or radiotherapy, development of cerebral metastases during therapy, neurological conditions, taking antiepileptic medication or medications likely to interfere with cerebral metabolism, and general anaesthesia within 24 h. White matter, basal ganglia, thalamus and the cerebellar cortex were analysed using regional SUV{sub max}, and the cerebral cortex, basal ganglia, thalamus and cerebellum were analysed using a regional relative uptake analysis in comparison to maximal cortical uptake. Scans from 30 patients (age range 11 months to 16 years, mean age 10 years 5 months) were included. All regions showed increasing SUV{sub max} with age. The parietal, occipital, lateral temporal and medial temporal lobes showed lower rates of increasing FDG uptake causing changing patterns of regional FDG uptake during childhood. The cortical regions showing the most intense uptake in early childhood were the parietal and occipital lobes. At approximately 7 years of age these regions had relatively less uptake than the frontal lobes and at approximately 10 years of age these regions had relatively less uptake than the thalamus. Relative FDG uptake in the brain has not reached an adult pattern by 1 year of age, but continues to change up to 16 years of age. The changing pattern is due to different regional rates of increasing cortical FDG uptake, which is less rapid in the parietal, occipital and temporal lobes than in the frontal lobes. (orig.)

    Subarachnoid hemorrhage is the most common cause of cerebral salt wasting syndrome. There are few reports of this condition in infectious meningitis. We describe a patient with hyponatremia and bacterial meningitis. Hyponatremia rapidly improved after administration of sodium chloride. The purpose of this report is to alert clinicians to the fact that hyponatremic patients with central nervous system disease do not necessarily have a syndrome of inappropriate secretion of antidiuretic hormone (SIADH), but may have cerebral salt wasting syndrome. By contrast with SIADH, the treatment requires saline administration.

    Cerebral salt wasting syndrome (CSW-cerebral salt wasting) was first described in 1950 by Peters. This syndrome can occur in patients who have sustained damage to the central nervous system (e.g. patients with subarachnoid bleeding, bacterial meningitis or after neurosurgery). Patients present with excessive natriuresis and hyponatremic dehydration. Differentiating this syndrome with the syndrome of inappropriate antidiuretic hormone secretion (SIADH-syndrome of inappropriate antidiuretic hormone secretion), which may occur in the same group of patients, is necessary in order to administer the correct treatment which consists of fluid restriction and sodium replacement in SIADH and fluid and sodium replacement as well as occasional mineralocorticoid therapy in CSW.

    Fat embolism syndrome (FES) is a rare but a serious clinical catastrophe occurring after traumatic injury to long bones. Cerebral involvement in the absence of pulmonary or dermatological manifestation on initial presentation may delay the diagnosis of cerebral fat embolism (CFE). We discuss a case series of CFE which posed a challenge in diagnosis. The clinical presentations of these patients did not satisfy the commonly used clinical criteria for aiding the diagnosis of FES. Early MRI brain (DWI and T2 weighted sequences) in patients with neurological symptoms after trauma even in the absence of pulmonary and dermatological findings should be the goal. PMID:21957425

    2015-12-01

    We report two cases of neuromyelitis optica patients with progressive cerebral atrophy. The patients exhibited characteristic clinical features, including elderly onset, secondary progressive tetraparesis and cognitive impairment, abnormally elevated CSF protein and myelin basic protein levels, and extremely highly elevated serum anti-AQP-4 antibody titer. Because neuromyelitis optica pathology cannot switch from an inflammatory phase to the degenerative phase until the terminal phase, neuromyelitis optica rarely appears as a secondary progressive clinical course caused by axonal degeneration. However, severe intrathecal inflammation and massive destruction of neuroglia could cause a secondary progressive clinical course associated with cerebral atrophy in neuromyelitis optica patients.

  6. Electrical Cerebral Stimulation Modifies Inhibitory Systems

    Cuéllar-Herrera, M.; Rocha, L.

    2003-09-01

    Electrical stimulation of the nervous tissue has been proposed as a method to treat some neurological disorders, such as epilepsy. Epileptic seizures result from excessive, synchronous, abnormal firing patterns of neurons that are located predominantly in the cerebral cortex. Many people with epilepsy continue presenting seizures even though they are under regimens of antiepileptic medications. An alternative therapy for treatment resistant epilepsy is cerebral electrical stimulation. The present study is focused to review the effects of different types of electrical stimulation and specifically changes in amino acids.

    Feeding difficulties are common in children with cerebral palsy and have an effect on growth, nutritional state, general health, social interaction and behaviour and developmental outcomes. Many factors have an effect on feeding ability. Identification of these factors and amelioration of their impact on feeding difficulties is essential to promote adequate growth and nutrition. Appropriate assessment and management is best achieved by a multiprofessional team skilled in the care of children with cerebral palsy and feeding impairments. Feeding difficulties must be considered within the wider context of family and social circumstance.

  8. Pathophysiology of muscle contractures in cerebral palsy.

    Science.gov (United States)

    Mathewson, Margie A; Lieber, Richard L

    2015-02-01

    Patients with cerebral palsy present with a variety of adaptations to muscle structure and function. These pathophysiologic symptoms include functional deficits such as decreased force production and range of motion, in addition to changes in muscle structure such as decreased muscle belly size, increased sarcomere length, and altered extracellular matrix structure and composition. On a cellular level, patients with cerebral palsy have fewer muscle stem cells, termed satellite cells, and altered gene expression. Understanding the nature of these changes may present opportunities for the development of new muscle treatment therapies.

    Full Text Available INTRODUÇÃO: Nos últimos anos, tem havido relatos de anormalidades do fluxo sanguíneo cerebral em indivíduos com o abuso de cocaína, detectadas por meio de tomografia computadorizada por emissão de fóton único (SPECT. Esse padrão anormal de perfusão cerebral tem sido associado a prejuízos cognitivos mas não a alterações observáveis por meio de exames de neuroimagem estrutural. Um problema envolvendo a maioria dos trabalhos publicados sobre esse tema é a inclusão de um grande número de usuários de heroína nas amostras estudadas. Essa outra droga também parece afetar o padrão de perfusão cerebral, particularmente durante estados de abstinência. MÉTODOS: Quatorze pacientes dependentes de cocaína (nenhum com uso de opióides e 14 voluntários normais (grupo controle foram submetidos a exames de SPECT com dímero de etil-cisteína marcado com tecnécio-99m. A análise dos exames de SPECT foi realizada por meio de análise visual qualitativa das imagens obtidas (procedimento padrão na prática clínica, realizada por um radiologista não informado sobre o diagnóstico dos indivíduos avaliados. RESULTADOS: A análise visual revelou um padrão sugestivo de irregularidades do fluxo sangüíneo cerebral em nove pacientes, mas em apenas dois controles (p = 0,018; teste exato de Fisher bicaudal. CONCLUSÕES: Anormalidades de circulação cerebral podem ter relação com prejuízos cognitivos relatados em populações de dependentes de cocaína. Embora déficits de perfusão cerebral associados ao uso de cocaína possam ser irreversíveis, têm surgido relatos na literatura de tratamentos para essas anormalidades de fluxo sangüíneo.

    We report a case of cerebral toxoplasmosis in a patient with stage IV C[sub 1] AIDS who presented hyperdense CT images 13 days after beginning antitoxoplasma treatment. These lesions could be caused by calcifications or blood. The attenuation values lead us to believe that they are calcium. Intracranial calcification in adult cerebral toxoplasmosis is an uncommon finding. Its presence in AIDS patients should not suggest any etiology other than toxoplasmosis. (Author) 16 refs.

    2013-01-01

    Aneurysmal subarachnoid hemorrhage- (aSAH-) associated vasospasm constitutes a clinicopathological entity, in which reversible vasculopathy, impaired autoregulatory function, and hypovolemia take place, and lead to the reduction of cerebral perfusion and finally ischemia. Cerebral vasospasm begins most often on the third day after the ictal event and reaches the maximum on the 5th-7th postictal days. Several therapeutic modalities have been employed for preventing or reversing cerebral vasospasm. Triple "H" therapy, balloon and chemical angioplasty with superselective intra-arterial injection of vasodilators, administration of substances like magnesium sulfate, statins, fasudil hydrochloride, erythropoietin, endothelin-1 antagonists, nitric oxide progenitors, and sildenafil, are some of the therapeutic protocols, which are currently employed for managing patients with aSAH. Intense pathophysiological mechanism research has led to the identification of various mediators of cerebral vasospasm, such as endothelium-derived, vascular smooth muscle-derived, proinflammatory mediators, cytokines and adhesion molecules, stress-induced gene activation, and platelet-derived growth factors. Oral, intravenous, or intra-arterial administration of antagonists of these mediators has been suggested for treating patients suffering a-SAH vasospam. In our current study, we attempt to summate all the available pharmacological treatment modalities for managing vasospasm.

    The functional outcome of cerebral hemodynamics in the chronic stage of juvenile hydrocephalus was determined using single photon emission computed tomography (SPECT). Five patients including three with aqueductal stenosis, one with post-meningitic hydrocephalus, and one case with hydrocephalus having developed after repair of a huge occipital encephalocele. Early images of cerebral blood flow (CBF) were obtained 25 minutes after intravenous injection of 123-I-iodoamphetamine (IMP), and late images were scanned 3 hours later. Cerebral blood volume (CBV) was also measured using {sup 99m}Tc in three patients. Twenty cases with adult communicating hydrocephalus were also investigated from the point of view of shunt effectiveness. Although there was no remarkable change in the cerebrovascular bed in the juvenile cases, CBF of the remnant brain parenchyma was good irrespective of the degree of ventricular dilatation. There was a periventricular-related IMP uptake in each case; however, it somehow matched the ventricular span. Functional outcome one to 23 years after the initial shunt operation was good in every case, despite multiple shunt revisions. Redistribution on late images had no bearing on clinical states. In adult cases, 8 patients with effective shunting demonstrated a relatively localized periventricular low perfusion, with preoperative increased cerebrospinal fluid (CSF) pressure. On the contrary, 12 patients with no improvement with or without ventricular-reduced IMP uptake, despite low CSF pressure. The present study indicates that periventricular hemodynamics may play an important role in cerebral function compromised by hydrocephalus. (J.P.N.).

    2009-11-01

    Cerebral salt-wasting (CSW), or renal salt-wasting (RSW), has evolved from a misrepresentation of the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) to acceptance as a distinct entity. Challenges still confront us as we attempt to differentiate RSW from SIADH, ascertain the prevalence of RSW, and address reports of RSW occurring without cerebral disease. RSW is redefined as 'extracellular volume depletion due to a renal sodium transport abnormality with or without high urinary sodium concentration, presence of hyponatremia or cerebral disease with normal adrenal and thyroid function.' Our inability to differentiate RSW from SIADH lies in the clinical and laboratory similarities between the two syndromes and the difficulty of accurate assessment of extracellular volume. Radioisotopic determinations of extracellular volume in neurosurgical patients reveal renal that RSW is more common than SIADH. We review the persistence of hypouricemia and increased fractional excretion of urate in RSW as compared to correction of both in SIADH, the appropriateness of ADH secretion in RSW, and the importance of differentiating renal RSW from SIADH because of disparate treatment goals: fluid repletion in RSW and fluid restriction in SIADH. Patients with RSW are being incorrectly treated by fluid restriction, with clinical consequences. We conclude that RSW is common and occurs without cerebral disease, and propose changing CSW to RSW.

    The present study on schizophrenics dealt with the relationship of regional cerebral blood flow (rCBF) to age, disease duration, and treatment length with chlorpromazine hydrochloride (CPZ). Regional cerebral blood flow in 28 cerebral regions of interest was measured by iv injection of /sup 133/X in 54 schizophrenic patients and 39 healthy volunteers. Neither age nor dosage of CPZ significantly influenced rCBF. All patients, including 11 treated for a short period of time (6 months or less), were characterized by having a decreased rCBF over the whole cerebrum. Thirty-four patients treated for a long period of time (2 years or more) had a varied rCBF distribution in the left hemisphere, with the most predominant feature being the decrease in rCBF in the frontal lobe (i.e., hypofrontality); however, there was no linear correlation between rCBF and disease duration. A decreased rCBE in the right occipital region was seen in patients with paranoid schizophrenia, suggesting that manifestations of symptoms may depend on disturbed regions. These results suggest that cerebral dysfunction in schizophrenic patients may not be restricted to the frontal lobe, but cover the whole cerebrum, and that nonuniform dysfunction in various regions of the cerebrum, including the frontal lobe, may be involved in manifestations of symptoms.

    Cerebral edema causes intracranial hypertension (ICH) which leads to severe outcome of patients in the clinical setting. Effective anti-edema therapy may significantly decrease the mortality in a variety of neurological conditions. At present drug treatment is a cornerstone in the management of cerebral edema. Osmotherapy has been the mainstay of pharmacologic therapy. Mannitol and hypertonic saline (HS) are the most commonly used osmotic agents. The relative safety and efficacy of HS and mannitol in the treatment of cerebral edema and reduction of enhanced ICP have been demonstrated in the past decades. Apart from its osmotic force, HS exerts anti-edema effects partly through inhibition of Na(+)-K(+)-2Cl(-) Cotransporter-1 (NKCC1) and aquaporin 4 (AQP4) expression in astrocytes. Melatonin may also reduce brain edema and exert neuroprotective effect on several central nervous system diseases through inhibition of inflammatory response. The inhibitors of Na/H exchanger, NKCC and AQP4 may attenuate brain edema formation through inhibition of excessive transportation of ion and water from blood into the cerebral tissue. In this review we survey some of the most recent findings in the drug treatment of brain edema focusing on the use of osmotherapy, melatonin and inhibitors of ion cotransporters and water channels. A better understanding of the molecular mechanism of these agents would help to improve in the clinical management of patients with brain edema.

    A simple, inexpensive method for measuring the cerebral circulation time (CCT) was developed. The CCT was considered to be equal to the time that an intravenously injected bolus of sodium pertechnetate Tc 99m took to go from the subclavian artery to the posterior venous confluence. The dilution curves were externally recorded at these two vessels. Particular attention was given to the curve treatment. The computer programmes were specially conceived in order to detect and, if possible, correct the experimental curve defects. Several reliability criteria were also defined in order to test the validity of each measurement. From a physiological point of view, the CCT is equal to the ratio of the global cerebral blood volume to the global cerebral blood flow. Thus, it can be widely applied in clinical research. For example, in a study of the relationship between CCT and age, sex and light cerebrovascular impairment, the technique was sensitive enough to discriminate between healthy subjects and patients suffering from-transient ischemic attack, or regressive stroke, and to show the action of a drug on the cerebral circulation in such patients.

    We have defined a novel cerebral hemodynamic index, a time constant of the cerebral arterial bed (τ), the product of arterial compliance (C(a)) and cerebrovascular resistance (CVR). C(a) and CVR were calculated based on the relationship between pulsatile arterial blood pressure (ABP) and transcranial Doppler cerebral blood flow velocity. This new parameter theoretically estimates how fast the cerebral arterial bed is filled by blood volume after a sudden change in ABP during one cardiac cycle. We have explored this concept in 11 volunteers and in 25 patients with severe stenosis of the internal carotid artery (ICA). An additional group of 15 subjects with non-vascular dementia was studied to assess potential age dependency of τ. The τ was shorter (p = 0.011) in ICA stenosis, both unilateral (τ = 0.18 ± 0.04 s) and bilateral (τ = 0.16 ± 0.03 s), than in controls (τ = 0.22 ± 0.0 s). The τ correlated with the degree of stenosis (R = -0.62, p = 0.001). In controls, τ was independent of age. Further study during cerebrovascular reactivity tests is needed to establish the usefulness of τ for quantitative estimation of haemodynamics in cerebrovascular disease.

The patients weredevided into two subgroups depending on whether they had vascular parkinsonism (VP (N-22 or idiopathicParkinson disease (N-28. The control group consisted of 30 patients who had ischemic stroke.The conventional transcranial dopler sonography was performed to evaluate the cerebral blood flow.To evaluate the cognitive impairment we performed the mini mental state examination to patients withparkinsonism.Results Patients with vascular parkinsonism have greater cognitive disturbances than patients withParkinson disease. In most of the parkinsonian patients the cerebral blood flow was decreased and themicroangiopathy was present.Conclusion In most patients with parkinsonism, the cerebral blood flow was decreased as a consequenceof microangiopathy. In our opinion, this led to lacunar infarction in VP patients, but can also bea risk factor for developing the same changes in patients with idiopathic Parkinson disease.

    The purpose of this study was to determine the technical capacity and diagnostic accuracy of 3D time-of-flight magnetic resonance angiography (MRA) in suspected cerebral vasculitis in a retrospective analysis of MRA and digital subtraction angiography (DSA) in 14 young patients with clinical and/or radiological suspicion of cerebral vasculitis. A total of nine arteries were evaluated in each patient. Consensus review of DSA by three observers was the reference standard. The sensitivity for detecting a stenosis varied from 62 to 79% for MRA and from 76 to 94% for DSA, depending on the observer. The specificity for detecting a stenosis varied from 83 to 87% for MRA and from 83 to 97% for DSA. Using the criterion ''more than two stenoses in at least two separate vascular distributions'' to consider the examination as being true positive, the false-positive rates for MRA and DSA were comparable. MRA plays a role as the first angiographical examination in the diagnostic work-up of suspected cerebral vasculitis. When more than two stenoses in at least two separate vascular distributions are depicted on MRA, DSA is not expected to add a significant diagnostic contribution in a patient with suspected cerebral vasculitis. DSA remains necessary when MRA is normal or when less than three stenoses are seen. (orig.)

    The clinical significance of cerebral microbleeds (CMB) in patients hospitalized with atrial fibrillation (AF) and cerebral ischemia is unclear. We aimed to determine the prevalence of CMB in this population and determine the future risk of intracerebral hemorrhage (ICH) and cerebral infarction (CI). The medical records and brain imaging of patients hospitalized with cerebral ischemia due to AF between 2008 and 2011 were reviewed. Followup was obtained through medical record review, mailed survey, and acquisition of death certificates. Prevalence was calculated from those patients with a hemosiderin-sensitive MRI sequence. Recurrent CI and ICH were calculated using Kaplan-Meier curves censored at 3 years. Among 426 patients hospitalized with cerebral ischemia due to AF, 134 had an MRI with hemosiderin-sensitive sequences. The prevalence of CMB was 27.6%. At 3 years, 90.6% of CMB-negative patients were overall stroke free (ICH and CI) compared to 78.6% CMB-positive patients (p = 0.0591). Only one patient in the CMB-positive group had an ICH distant to the CMB. There was a nonsignificant trend toward higher recurrent CI, recurrent overall stroke rate, and mortality in patients with 5 or more CMB compared to 0-4 CMB. The rate of prospective CI in patients with prior cerebral ischemia due to AF is higher than the rate of ICH in patients with CMB. Further study is warranted to assess larger numbers of patients to determine appropriate antithrombotic use in this high-risk population.

    Full Text Available Objective To summarize the clinical data and pathological features of 10 cases of cerebral lobar hemorrhage related with cerebral amyloid angiopathy (CAA diagnosed pathologically, thereby to improve the knowledge and diagnosis of the disease. Methods The clinical data of 10 cases of cerebral lobar hemorrhage related with CAA, collected in the General Hospital of Shenyang Command from 1983 up to now, were retrospectively analyzed, and the clinical and neuropathological features of these cases were summarized. Results Of the 10 patients, 2 suffered from single lobar hemorrhage and 8 multiple lobar hemorrhage, all of them were confirmed pathologically to have ruptured into the subarachnoid space. Pathological examination revealed microaneurysm in 2 cases, "double barrel" change in 4 cases, multiple arteriolar clusters in 5 cases, obliterative onion-liked intima change in 4 cases, and fibrinoid necrosis of vessel wall in 7 cases. In addition, neurofibrillary tangles were found in 8 cases, and senile plaque was observed in 5 cases. Conclusions Cerebral lobar hemorrhage related with CAA is mainly located in the parietal, temporal and occipital lobes, readily breaking into the subarachnoid space, and it is often multiple and recurrent. The CAA associated microvasculopathy was found frequently in the autopsy sample of CAA related cerebral lobar hemorrhage, and it may contribute to the pathogenesis of cerebral hemorrhage.

    This study was intended to evaluate radiation risk to patients during cerebral interventions and the contribution to this risk from work practices. Thirty nine patients undergoing cerebral interventions in a digital subtraction angiography suite were included in this study. Patients who underwent cerebral interventions were categorised into two groups according to the number of cerebral interventions performed on them, and their effective doses were calculated. The effective dose for patients undergoing a single cerebral intervention (group A) varied from 1.55 to 15.9 mSv and for multiple cerebral interventions (group B) varied from 16.52 to 43.52 mSv. Two patients who underwent multiple cerebral interventions (group B) had alopecia of the irradiated scalp.

  4. Cerebral blood flow and metabolism during sleep.

    Madsen, P L; Vorstrup, S

    1991-01-01

    A review of the current literature regarding sleep-induced changes in cerebral blood flow (CBF) and cerebral metabolic rate (CMR) is presented. Early investigations have led to the notion that dreamless sleep was characterized by global values of CBF and CMR practically at the level of wakefulness, while rapid eye movement (REM) sleep (dream sleep) was a state characterized by a dramatically increased level of CBF and possibly also of CMR. However, recent investigations firmly contradict this notion. Investigations on CBF and CMR performed during non-REM sleep, taking the effect of different levels of sleep into consideration, show that light sleep (stage II) is characterized by global levels of CBF and CMR only slightly reduced by 3-10% below the level associated with wakefulness, whereas CBF and CMR during deep sleep (stage III-IV) is dramatically reduced by 25-44%. Furthermore, recent data indicate that global levels of CBF and CMR are about the same during REM sleep as in wakefulness. On the regional level, deep sleep seems to be associated with a uniform decrease in regional CBF and CMR. Investigations concerning regional CBF and CMR during REM sleep are few but data from recent investigations seem to identify site-specific changes in regional CBF and CMR during REM sleep. CBF and CMR are reflections of cerebral synaptic activity and the magnitude of reduction in these variables associated with deep sleep indicates that overall cerebral synaptic activity is reduced to approximately one-half the level associated with wakefulness, while cerebral synaptic activity levels during REM sleep are similar to wakefulness. However, even though the new understanding of CBF and CMR during sleep provides significant and important information of the brain's mode of working during sleep, it does not at its current state identify the physiological processes involved in sleep or the physiological role of sleep.

    2013-01-01

    Objective: To review the discoveries underpinning the introduction of cerebral PET scanning and highlight its modern applications. Background: Important discoveries in neurophysiology, brain metabolism, and radiotracer development in the post–World War II period provided the necessary infrastructure for the first cerebral PET scan. Methods: A complete review of the literature was undertaken to search for primary and secondary sources on the history of PET imaging. Searches were performed in PubMed, Google Scholar, and select individual journal Web sites. Written autobiographies were obtained through the Society for Neuroscience Web site at www.sfn.org. A reference book on the history of radiology, Naked to the Bone, was reviewed to corroborate facts and to locate references. The references listed in all the articles and books obtained were reviewed. Results: The neurophysiologic sciences required to build cerebral PET imaging date back to 1878. The last 60 years have produced an evolution of technological advancements in brain metabolism and radiotracer development. These advancements facilitated the development of modern cerebral PET imaging. Several key scientists were involved in critical discoveries and among them were Angelo Mosso, Charles Roy, Charles Sherrington, John Fulton, Seymour Kety, Louis Sokoloff, David E. Kuhl, Gordon L. Brownell, Michael Ter-Pogossian, Michael Phelps, and Edward Hoffman. Conclusions: Neurophysiology, metabolism, and radiotracer development in the postwar era synergized the development of the technology necessary for cerebral PET scanning. Continued use of PET in clinical trials and current developments in PET-CT/MRI hybrids has led to advancement in diagnosis, management, and treatment of neurologic disorders. PMID:23460618

    Transaxillary or transbrachial approaches to the cerebral vessels have been reported, but selective angiography of all four vessels has not been possible through one route. In this report, a new technique for selective cerebral angiography with transbrachial approach is described. One hundred and twenty three patients with cerebral infarction, vertebrobasilar insufficiency, intracerebral hemorrhage, epilepsy, or cerebral tumor were examined. Those patients consisted of 85 outpatients and 38 inpatients whose age ranged from 15 years old to 82 years old. The patients were examined via the transbrachial approach (97 cases via the right brachial, 29 cases via the left). Materials included a DSA system (Digital Fluorikon 5000, General Electric Co.), a 4 French tight J-curved Simmons 80-cm catheter, a 19-gauge extra-thin-wall Seldinger needle, and a J/Straight floppy 125-cm guide-wire. Generally, the volume of the contrast agent (300 mgI/ml iopamidol) used in the common carotid artery angiogram was 6 ml, while that used in the vertebral artery angiogram was 4 ml. If catheterization of the vertebral artery or right common carotid artery was unsuccessful, about 8 ml of the contrast agent was injected into the subclavian or branchiocephalic artery. Definitive diagnosis and a decision on proper treatment of the patients can be easily obtained, and the results were clinically satisfactory. Moreover, no complications were encountered in this study. This new technique making a transbrachial approach to the cerebral vessels using the DSA system is introduced here. Neurosurgeons can use this technique easily, and they will find that it provides them with all the information they need about the patient. (author).

In the present paper, the in situ Raman spectra of the cerebral cortex of the birth, teenage and aged monkeys were achieved for the first time. The results show that the Raman spectra for the different age monkey cerebral cortex exhibit most obvious changes in the regions of 1000-1400 and 2800-3000 cm(-1). With monkey growing up, the relative intensities of the Raman bands at 1313 and 2885 cm(-1) mainly assigned to CH2 chain vibrational mode of lipid become stronger and stronger whereas the relative intensities of the Raman bands at 1338 and 2932 cm(-1) mainly assigned to CH3 chain vibrational mode of protein become weaker and weaker. In addition, the two new Raman bands at 1296 and 2850 cm(-1) are only observed in the aged monkey cerebral cortex, therefore, the two bands can be considered as a character or "marker" to differentiate the caducity degree with monkey growth In order to further explore the changes, the relative intensity ratios of the Raman band at 1313 cm(-1) to that at 1338 cm(-1) and the Raman band at 2885 cm(-1) to that at 2 932 cm(-1), I1313/I1338 and I2885/I2932, which are the lipid-to-protein ratios, are introduced to denote the degree of the lipid content. The results show that the relative intensity ratios increase significantly with monkey growth, namely, the lipid content in the cerebral cortex increases greatly with monkey growth. So, the authors can deduce that the overmuch lipid is an important cause to induce the caducity. Therefore, the results will be a powerful assistance and valuable parameter to study the order of life growth and diagnose diseases.

    Full Text Available New cerebral monitoring techniques allow direct measurement of brain oxygenation and metabolism. Investigation using these new tools has provided additional insight into the understanding of the pathophysiology of acute brain injury and suggested new ways to guide management of secondary brain injury. Studies of focal brain tissue oxygen monitoring have suggested ischemic thresholds in focal regions of brain injury and demonstrated the interrelationship between brain tissue oxygen tension (P bt O 2 and other cerebral physiologic and metabolic parameters. Jugular venous oxygen saturation (SjVO 2 monitoring may evaluate global brain oxygen delivery and consumption, providing thresholds for detecting brain hypoperfusion and hyperperfusion. Furthermore, critically low values of P bt O 2 and SjVO 2 have also been predictive of mortality and worsened functional outcome, especially after head trauma. Cerebral microdialysis measures the concentrations of extracellular metabolites which may be relevant to cerebral metabolism or ischemia in focal areas of injury. Cerebral blood flow may be measured in the neurointensive care unit using continuous methods such as thermal diffusion and laser Doppler flowmetry. Initial studies have also attempted to correlate findings from advanced neuromonitoring with neuroimaging using dynamic perfusion computed tomography, positron emission tomography, and Xenon computed tomography. Additionally, new methods of data acquisition, storage, and analysis are being developed to address the increasing burden of patient data from neuromonitoring. Advanced informatics techniques such as hierarchical data clustering, generalized linear models, and heat map dendrograms are now being applied to multivariable patient data in order to better develop physiologic patient profiles to improve diagnosis and treatment.

Tal patología refleja también en el comportamiento de la familia comprometida. Esa familia debe recibir apoyo de los profesionales para enfrentar el problema. El estudio pretendió investigar cómo las madres participan en el tratamiento de sus hijos, así como las posibles dudas que poseen en relación al cuidado en casa de los mismos. Es un estudio descriptivo con planteo cualitativo, realizado en junio de 2008 en el Núcleo de Tratamiento e Estimulación Precoz. Fueron entrevistadas 12 madres de niños con parálisis cerebral por medio de un plan de entrevista estructurado en parte. Percibimos que esas madres poseen una participación incipiente en el tratamiento de los hijos, limitándose al acompañamiento y siendo dependientes de orientaciones profesionales. Es necesario que sean adoptadas estrategias de enfrentamiento por padres y profesionales, como ser: ofrecimiento de explicaciones sobre la patología, mayor participación de los padres en el tratamiento y visitas domiciliarias.

    Full Text Available El cadmio es un agente químico tóxico importante debido a su creciente nivel en el medio ambiente como resultado de prácticas industriales y agrícolas. Como perturbador endocrino, el cadmio modifica la secreción de hormonas hipofisarias. Los efectos indirectos del cadmio provocan la generación de especies reactivas de oxígeno y reducen la actividad de las proteínas implicadas en las defensas antioxidantes. La melatonina es conocida como un potente antioxidante, scavenger de radicales libres y quelante de metales sintetizada en la glándula pineal. De esta manera, las acciones antioxidantes de esta indolamina protegen frente a la peroxidación lipídica y el daño oxidativo de los radicales y de sus productos tóxicos. Los trabajos recopilados en esta revisión ponen de manifiesto la capacidad antioxidante de la melatonina y, por lo tanto, su posible papel protector frente a la toxicidad del cadmio en lo que se refiere al estrés oxidativo y peroxidación lipídica inducidos por la exposición a este metal.

    Full Text Available La mortalidad global por accidente cerebrovascular (ACV ha disminuido en las últimas tres décadas, probablemente debido a un mejor control de los factores de riesgo vascular. La mortalidad hospitalaria por ACV ha sido tradicionalmente estimada entre 6 y 14% en la mayoría de las series comunicadas. Sin embargo, los datos de ensayos clínicos recientes sugieren que esta cifra sería sustancialmente menor. Se revisaron datos de pacientes internados con diagnóstico de ACV del Banco de Datos de Stroke de FLENI y los registros institucionales de mortalidad entre los años 2000 y 2010. Los subtipos de ACV isquémicos se clasificaron según criterios TOAST y los ACV hemorrágicos en hematomas intrapanquimatosos, hemorragias subaracnoideas aneurismáticas, malformaciones arteriovenosas y otros hematomas intraparenquimatosos. Se analizaron 1514 pacientes, 1079 (71% con ACV isquémico (grandes vasos 39%, cardioembólicos 27%, lacunares 9%, etiología indeterminada 14%, otras etiologías 11% y 435 (29% con ACV hemorrágico (intraparenquimatosos 27%, hemorragia subaracnoidea 30%, malformaciones arteriovenosas 25% y otros hematomas espontáneos 18%.

No se registraron muertes asociadas al uso de fibrinolíticos endovenosos. La mortalidad intrahospitalaria en pacientes con ACV isquémico y hemorrágico en nuestro centro fue baja. El manejo en un centro dedicado a las enfermedades neurológicas y el enfoque multidisciplinario por personal médico y no médico entrenado en el cuidado de la enfermedad cerebrovascular podrían explicar, al menos en parte, estos resultados.

    Full Text Available A revisão das investigações de Kleist sôbre a patologia cerebral mostram como suas idéias sôbre o dinamismo surgem a partir da realidade clínica. As investigações neurológicas servem de guia para as psicopatológicas. E, assim, por etapas, elaborou Kleist as noções dos "sistemas cerebrais" e seu papel no que tange às funções neurológicas e psíquicas. Uma função nervosa qualquer é assegurada pelo concurso de dois setores funcionais a que correspondem substratos anatômicos próprios; ao exercício complexo das funções da motilidade automática, por exemplo, correspondem várias estruturas anatômicas em todas as quais distinguem-se dois grupos de centros com sentido funcional diverso: um, a que cabe o papel de recepção e coordenação de estímulos, outro, de efetuação. Tal dualidade de funções primordiais é a base para o desempenho de atividades neurológicas ou psíquicas, ocorrendo tanto no setor da motilidade automática, como no da psicomotilidade, no da ação explícita, no da linguagem, no do pensamento abstrato. Foi a patologia que permitiu a Kleist a separação entre dois setores funcionais prepostos a elaboração do pensamento abstrato: aos campos 19 e 39 de Brodmann correspondem funções receptivo-coordenadoras prepostas à elaboração dos conceitos; a perturbação dessas funções conduz a uma desordem que consiste na dificuldade ou impossibilidade de elaboração dos conceitos isolados: desordem paralógia. O homem, porém, não pensa por meio de conceitos isolados; reúne-os em juízos, por meio de relações predicativas. Ê ao córtex cerebral frontal, campo 46, que dizem respeito tais funções de reunião, de efetuação do pensamento discursivo.

    Full Text Available INTRODUÇÃO: A isquemia cerebral é uma doença freqüente e de difícil tratamento médico. De particular interesse neurocirúrgico são as situações de vasoespasmo após hemorragia subaracnóidea, de oclusão temporária de vasos nas neurocirurgias e de tromboses de artérias intracranianas. A lesão cerebral resultante da isquemia depende da sua duração e pode ser agravada pela reperfusão do território isquêmico. Vários estudos clínicos e experimentais têm sido realizados para melhor entender esses fenômenos. OBJETIVO: Este trabalho visou a avaliação precoce dos efeitos da isquemia focal seguida da reperfusão no cérebro de gatos. MÉTODOS: A isquemia cerebral foi provocada por clipagem temporária da artéria cerebral média por tempos determinados com reperfusão durante 10 minutos, e avaliação foi efetuada através da análise da respiração mitocondrial no tecido isquemiado. Resultados - Houve redução significativa no consumo de O2 nas amostras de tecido cerebral isquemiado por 60 minutos, seguidos de 10 minutos de reperfusão, quando comparadas ao tecido cerebral contralateral (não isquemiado. CONCLUSÕES: Com base nos resultados obtidos, pode-se concluir que o tempo de duração da isquemia foi um fator determinante na alteração da respiração mitocondrial de gatos submetidos à isquemia e reperfusão de curta duração (alterações significativas apenas após 60 minutos de isquemia seguidos de 10 de reperfusão.OBJECTIVE: Brain ischemia is considered a disease difficult to be treated.

Foram feitos estudos genealógico, clínico e laboratorial, incluindo a dosagem de fenilalanina sérica. O interesse maior foi o de mostrar a normalidade do estudo histopatológico realizado por meio de biópsias cerebrais em 4 casos, apesar de não ter sido feito estudo histoquímico, atualmente considerado como necessário. Esta normalidade das biópsias não teve qualquer relação com o nível mental, com as alterações eletrencefalográficas cu com atrofias cerebrais assinaladas em alguns casos mediante encefalografia gasosa. Todos os casos foram tratados com dieta especial (tipo Lofenalac complementada com alimentos de baixo teor em fenilalanina.

The patients belong to three different families — three siblings. Genealogic, clinic and laboratorial studies have been done, including serum phenylalanin. The important aim was to show the normality of the histopathology performed through cerebral biopsy in four cases. Histochemical study has not been done. The normal cerebral biopsy did not show correlation with mental level, electroencephalographic alterations or with cerebral atrophies which were found in two cases by air encephalography. All cases have been treated with special diet (Lofenalac and some food with low phenylalanin level. After and before the diet phenylalanin determinations have been done, nevertheless, it is very soon indeed to conclude anything by now.

    Activation of the mammalian target of rapamycin (mTOR) leads to cell growth and survival. We tested the hypothesis that inhibition of mTOR would increase infarct size and decrease microregional O2 supply/consumption balance after cerebral ischemia-reperfusion. This was tested in isoflurane-anesthetized rats with middle cerebral artery blockade for 1h and reperfusion for 2h with and without rapamycin (20mg/kg once daily for two days prior to ischemia). Regional cerebral blood flow was determined using a C(14)-iodoantipyrine autoradiographic technique. Regional small-vessel arterial and venous oxygen saturations were determined microspectrophotometrically. The control ischemic-reperfused cortex had a similar blood flow and O2 consumption to the contralateral cortex. However, microregional O2 supply/consumption balance was significantly reduced in the ischemic-reperfused cortex. Rapamycin significantly increased cerebral O2 consumption and further reduced O2 supply/consumption balance in the reperfused area. This was associated with an increased cortical infarct size (13.5±0.8% control vs. 21.5±0.9% rapamycin). We also found that ischemia-reperfusion increased AKT and S6K1 phosphorylation, while rapamycin decreased this phosphorylation in both the control and ischemic-reperfused cortex. This suggests that mTOR is important for not only cell survival, but also for the control of oxygen balance after cerebral ischemia-reperfusion.

    Full Text Available Introduction. Reversible cerebral vasoconstriction syndrome is becoming widely accepted as a rare cause of both ischemic and haemorrhagic stroke and should be evocated in case of thunderclap headaches associated with stroke. We present the case of a patient with ischemic stroke associated with cortical subarachnoid haemorrhage (cSAH and reversible diffuse arteries narrowing, leading to the diagnosis of reversible vasoconstriction syndrome. Case Report. A 48-year-old woman came to the emergency department because of an unusual thunderclap headache. The computed tomography of the brain completed by CT-angiography was unremarkable. Eleven days later, she was readmitted because of a left hemianopsia. One day after her admission, she developed a sudden left hemiparesis. The brain MRI showed ischemic lesions in the right frontal and occipital lobe and diffuse cSAH. The angiography showed vasoconstriction of the right anterior cerebral artery and stenosis of both middle cerebral arteries. Nimodipine treatment was initiated and vasoconstriction completely regressed on day 16 after the first headache. Conclusion. Our case shows a severe reversible cerebral vasoconstriction syndrome where both haemorrhagic and ischemic complications were present at the same time. The history we reported shows that reversible cerebral vasoconstriction syndrome is still underrecognized, in particular in general emergency departments.

    Giftedness is defined as some special endowment or propensity for creativity, skill, and eminent achievement, found in relatively few individuals among the population. A high order of mental power (IQ), creativity, and motivation (task commitment) appear to be the most universally recognized attributes of the gifted. This report summarizes current knowledge of the cerebral correlates of intelligence and creativity, including physiological measures of EEG, cortical power spectrum, brain evoked potentials, and positron emission tomography. Controversy, debates, contentions, formal hypotheses, and research issues are considered. We are especially interested in the formulation of the deterministic function of EEG-brain dynamics. A CHAOS modeling on hierarchy of cognitive organization and cerebral processing in the gifted is suggested.

    Severe traumatic brain injury is associated with both acute and delayed neuro- logical injury. Cerebral vasospasm is commonly associated with delayed neurological decline in aneurysmal subarachnoid hemorrhage patients. However, the role played by vasospasm in traumatic brain injury is less clear. Vasospasm occurs earlier, for a shorter duration, and often without significant neurological consequence among traumatic brain injury patients. Detection and management strategies for vasospasm in aneurysmal subarachnoid hemorrhage are not easily transferrable to traumatic brain injury patients. We present a patient with a severe traumatic brain injury who had dramatic improvement following emergent decompressive hemicraniectomy. Two weeks after initial presentation he suffered a precipitous decline despite intensive surveillance. This case illustrates the distinct challenges of diagnosing cerebral vasospasm in the setting of severe traumatic brain injury.

    Cerebral palsy (CP) is the most common physical disability in early childhood. The worldwide prevalence of CP is approximately 2-2.5 per 1,000 live births. It has been clinically defined as a group of motor, cognitive, and perceptive impairments secondary to a non-progressive defect or lesion of the developing brain. Children with CP can have swallowing problems with severe drooling as one of the consequences. Malnutrition and recurrent aspiration pneumonia can increase the risk of morbidity and mortality. Early attention should be given to dysphagia and excessive drooling and their substantial contribution to the burden of a child with CP and his/her family. This review displays the important functional and anatomical issues related to swallowing problems in children with CP based on relevant literature and expert opinion. Furthermore, based on our experience, we describe a plan for approach of investigation and treatment of swallowing problems in cerebral palsy.

    In this book, a neuroradiologist and a neuropediatrician have combined forces to provide the widest possible knowledge in investigating cranial and cerebral disorders in infancy and childhood. Based on more than 20,000 pediatric CT examinations, with a follow-up time often exceeding ten years, the book aims to bridge interdisciplinary gaps and help radiologists, pediatricians and neurosurgeons solve the various problems of pediatric neuroradiology that frequently confront them. For each disease, the etiology, clinical manifestation, pathological lesions and radiological presentations are discussed, supported by extensive illustrations. Malformative, vascular, traumatic, tumoral, infectious and metabolic diseases are reviewed. Miscellaneous conditions presenting particular symptoms or syndromes are also studied, such as hydrocephalus and neurological complications of leukemia. Contents: Cerebral and cranial malformations; neurocutaneous syndromes; inherited metabolic diseases; infectious diseases - vascular disorders; intracranial tumors; cranial trauma - miscellaneous and subject index.

  16. Cerebral salt wasting syndrome: a case report.

    A case of hyponatraemia associated with subarachnoid haemorrhage is presented. The provisional diagnosis of an inappropriate antidiuresis was made and treatment with fluid restriction was instituted. However the patient continued to deteriorate as the diuresis continued and the hyponatraemia worsened, resulting in hypovolaema. The salt wasting syndrome was subsequently diagnosed and saline and fludrocortisone (0.2 mg/day) was initiated, reducing the renal salt loss, increasing the plasma sodium and improving the neurological status of the patient. Cerebral salt wasting syndrome is an important and under-recognised cause of hyponatraemia in neurosurgical patients, particularly in patients with subarachnoid hemorrhage. It is essential to differentiate it from the syndrome of inappropriate antidiuretic hormone secretion to avoid complications of hypovolaemia and reduced cerebral perfusion as illustrated by this case. Brain natriuretic peptide may be responsible for this syndrome although this requires further investigation.

    Eighty-three children with spastic cerebral palsy (CP) were examined with cranial CT. In 56 cases the CT findings were abnormal. The most frequent abnormality was atrophy, present in 44 patients. The frequency of pathologic CT increased with severity of the CP. Patients with CP of postnatal aetiology more often had abnormal CT than patients with other known causes. Pathologic CT findings were seen more often in patients with seizures than in patients without. Infarctions and hemiatrophy were much more frequent in patients with hemiplegia than in patients with other types of spastic CP. A special kind of central atrophy, called isolated atrophy around the cella media, is described. This condition was seen in 20% of cases, most often in hemi- and paraplegic patients. Early infarctions in the border areas between the vascular territories of the internal carotid and the posterior cerebral artery may be the reason for this kind of atrophy.

    The locations of cerebral infarctions were studied in 14 patients with tuberculous meningitis (TBM) and 173 patients with noninflammatory ischemic stroke (IS). In patients with TBM, 75% of infarctions occurred in the 'TB zone' supplied by medial striate and thalamoperforating arteries; only 11% occurred in the 'IS zone' supplied by lateral striate, anterior choroidal and thalamogeniculate arteries. In patients with IS, 29% of infarctions occurred in the IS zone, 29% in the subcortical white matter, and 24% in (or involving) the cerebral cortex. Only 11% occurred in the TB zone. Bilaterally symmetrical infarctions of the TB zone were common with TBM (71%) but rare with IS (5%). (orig.).

    Full Text Available Cerebral palsy (CP is the result of an injury to the developing brain during the antenatal, perinatal or postnatal period. Clinical manifestation relate to the areas affected. Patients with CP often present for elective surgical proce-dures to correct various deformities. Anaesthetic concerns of anaesthesia are intraoperative hypothermia , and slow emergence. Suxamethonium does not cause hyperkalaemia in these patients, and a rapid sequence induction may be indicated. Temperature should be monitored and an effort made to keep the patient warm. Cerebral abnormalities may lead to slow awakening; the patient should remain intubated until fully awake and airway reflexes have returned. Pulmonary infection can complicate the postoperative course. Postoperative pain management and the prevention of muscle spasms are important and drugs as baclofen and botulinum toxin are discussed. Epidural analgesia is particu-larly valuable when major orthopaedic procedures are performed.

    The traditional static view of the adult mammalian brain has been challenged by the realization of continuous generation of neurons from stem cells. Based mainly on studies in experimental animals, adult neurogenesis may contribute to recovery after brain insults and decreased neurogenesis has been implicated in the pathogenesis of neurological and psychiatric diseases in man. The extent of neurogenesis in the adult human brain has, however, been difficult to establish. We have taken advantage of the integration of {sup 14}C, generated by nuclear bomb tests during the Cold War, in DNA to establish the age of neurons in the major areas of the human cerebral cortex. Together with the analysis of the cortex from patients who received BrdU, which integrates in the DNA of dividing cells, our results demonstrate that whereas non-neuronal cells turn over, neurons in the human cerebral cortex are not generated postnatally at detectable levels, but are as old as the individual.
