Infarto Cerebral del territorio Vértebro-Basilar: Comunicación de una serie de pacientes asistidos en el Hospital de Clínicas de Montevideo

Introducción: El ataque cerebro vascular tiene una elevada incidencia y mortalidad en Uruguay representando, aquellos de la circulación posterior, un porcentaje importante de ellos. En este estudio describimos características basales, clínicas, diagnósticas y terapéuticas de una serie de pacientes con ataque cerebro vascular de la circulación posterior. Material y métodos: Estudio observacional descriptivo. Inclusión: pacientes con diagnóstico de ataque cerebro vascular de la circulación posterior atendidos en el Hospital de Clínicas entre junio de 2007 y 2014. Resultados: Se incluyeron 140 pacientes con una edad media de 68 años y elevada frecuencia de factores de riesgo clásicos para enfermedad cerebro vascular. Predominó la clínica cerebelosa y piramidal, con un puntaje medio bajo en la escala de NIHSS (5,2) y una baja sensibilidad de la Tomografía de cráneo para el diagnóstico. La etiología determinada más prevalente fue la cardioembolia. Un quinto de los pacientes consultó antes de las 4,5 horas y el 3,8% de los pacientes fue tratado con trombolisis iv. Discusión y comentarios: Se trata de la mayor serie de ataque cerebro vascular de la circulación posterior reportada en nuestro país, la forma de presentación fue similar a la descrita en la literatura. La escala de NIHSS infravaloró la severidad de este tipo de ataque cerebro vascular. La tomografia de cráneo tuvo baja sensibilidad diagnóstica y el porcentaje de resonancias magnéticas realizadas fue bajo. Un bajo número de pacientes consultó en ventana para trombolisis iv y solo al 3,8% de los casos se le realizó dicho tratamiento.

Cerebral misery perfusion diagnosed using hypercapnic blood-oxygenation-level-dependent contrast functional magnetic resonance imaging: a case report

Introduction Cerebral misery perfusion represents a failure of cerebral autoregulation. It is animportant differential diagnosis in post-stroke patients presenting with collapses in the presence of haemodynamically significant cerebrovascular stenosis. This is particularly the case when cortical or internal watershed infarcts are present. When this condition occurs, further investigation should be done immediately. Case presentation A 50-year-old Caucasian man presented with a stroke secondary to complete occlusion of his left internal carotid artery. He went on to suffer recurrent seizures. Neuroimaging demonstrated numerous new watershed-territory cerebral infarcts. No source of arterial thromboembolism was demonstrable. Hypercapnic blood-oxygenation-level-dependent-contrast functional magnetic resonance imaging was used to measure his cerebrovascular reserve capacity. The findings were suggestive of cerebral misery perfusion. Conclusions Blood-oxygenation-level-dependent-contrast functional magnetic resonance imaging allows the inference of cerebral misery perfusion. This procedure is cheaper and more readily available than positron emission tomography imaging, which is the current gold standard diagnostic test. The most evaluated treatment for cerebral misery perfusion is extracranial-intracranial bypass. Although previous trials of this have been unfavourable, the results of new studies involving extracranial-intracranial bypass in high-risk patients identified during cerebral perfusion imaging are awaited. Cerebral misery perfusion is an important and under-recognized condition in which emerging imaging and treatment modalities present the possibility of practical and evidence-based management in the near future. Physicians should thus be aware of this disorder and of recent developments in diagnostic tests that allow its detection.

Emerging pathogens in the central nervous system: a cerebral abscess by Streptococcus porcinus

Brain abscesses can cause an incapacitating neurological deicit in up to 50% of patients, thus the reduction of these sequelae becomes the main goal of its timely and speciic surgical and medical treatment. With technological advances in bacteriological identiication and diagnostic imaging, the clinical suspicion can be conirmed, and the speciic etiological agent can be identiied in a larger number of cases. New pathogens have emerged through this process, such as Streptococcus porcinus, in which the ability to affect the central nervous system has not been documented. A clinical case is presented of a brain abscess in an immunocompetent patient, and its favorable response to surgical drainage t hrough a skull burr h ole and nee dle aspiration with antibiotic therapy (ceftriaxone, metronidazole and vancomycin) is discussed.

Ansiedade pós acidente vascular cerebral

Se entendemos o Acidente vascular cerebral como um acontecimento incapacitante da vida dos pacientes, poderemos compreender as alterações comportamentais e emocionas que este provoca. No entanto, poucos estudos têm sido realizados acerca desta temática, tendo assim este estudo como objetivo verificar se existe uma associação clara entre a ansiedade e um determinado tipo de AVC. Aplicou-se a escala de Montereal, o State-Trait Anxiety lnventory e o Inventario Neuropsiquiátrico numa amostra constituída por pacientes que tenham sofrido AVC no período de três meses a um ano, e num grupo controlo. Os resultados mostram que não existem diferenças significativas no que respeita à ansiedade nos pacientes com AVC anterior. Conclui-se que não existe um aumento de ansiedade, mas que os défices visuo-espaciais e atencionais são mais significativos no AVC anterior. / ABSTRACT: lf we recognize Stroke as an event that can incapacitate the patients' life, we can comprehend the behaviour and emotional changes that this provokes. One of the psychiatric symptoms usually associated to Stroke is anxiety. However, few studies have been made concerning this matter, being the purpose of this study to verify if a clear association exists between anxiety and a certain type of Stroke. The Montereal Cognitiva Assessment, State-Trait Anxiety lnventory, and Neuropsychiatric lnventory were applied in a sample consisting of patients that have suffered Stroke in the period of three months to one year, and in a control group. The results show no significant differences in what regards to anxiety in patients with previous Stroke. We conclude that there is no increase in anxiety after stroke, but cognitive deficits in visual-spatial and attentional are most significant in subjects with previous stroke.

Software de comunicación para personas con parálisis cerebral

El objetivo de este Trabajo de Fin de Grado es la creación de un software para la comunicación de personas con discapacidad exclusivamente motriz, incluyendo el habla, pero sin tener afectada la cognición; concretamente va dirigido a un niño que padece una parálisis cerebral. Dicho software se ha desarrollado en dos programas separados. El primero es un software de seguimiento de pupila basado en la tecnología de EyeTracking, para lo que se usa un ratón de mirada proporcionado por un programa ya existente. La aportación en este apartado ha sido crear una interfaz, como capa superior, mediante botones que ejecutan las acciones correspondientes a seleccionar el método de comunicación y las opciones correspondientes a cada método que ofrece el sistema. Nuestro niño, Moisés, sufre disponía, lo que implica fluctuación ene el tono muscular, unas veces hipertónico y otras hipotónico en distintas partes de su cuerpo, afectándole a la sujeción de la cabeza. Por ese motivo se ha desarrollado un segundo programa que funciona con ratón y teclado, al cual se le ha añadido un pulsador. Incluye un menú para seleccionar distintas formas de comunicación. Las opciones de este menú se le ofrecen al usuario de forma secuencial ya que solo podrá comunicarse con el sistemas mediante clicks de ratón o pulsaciones de teclado. En España la empresa Vía Libre de la fundación ONCE vende materiales ortopédicos y de comunicación, todos con licencia de uso, como el usado por Stephen Hawking, no asequibles a familias que ya tienen gastos en sillas, adaptadores, y material ortopédico. Este segundo programa ha sido probado y modificado según las principales necesidades de comunicación de Moisés, es de código abierto y puede ser descargable desde https://sourceforge.net/p/clickspeak/

Clinical efficacy and safety of edaravone therapy in acute cerebral haemorrhage

Purpose: To evaluate the clinical efficacy and safety of edaravone in the treatment of acute cerebral haemorrhage (ACH). Methods: This study recruited 120 patients who developed ACH. The patients were divided into control and treatment groups with 60 patients per group. The control group underwent conventional treatment and the treatment group also received intravenous edaravone. The volumes of cerebral edema and cerebral hematoma, high-sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6) levels, and Chinese Stroke Scale (CSS) score before and after treatment were compared between the two groups. Results: The respective cerebral edema volumes of the control and treatment groups decreased from 20.99 ± 12.09 and 21.80 ± 12.01 mL on day 0 to 11.23 ± 6.34 and 12.11 ± 5.98 mL at day 7 and 4.69 ± 4.03 and 4.64 ± 3.9 mL on day 14 (P < 0.05). The respective cerebral hematoma volumes of the control and treatment groups decreased from 18.98 ± 12.04 and 18.97 ± 12.07 mL on day 0 to 12.34 ± 6.57 and 11.89 ± 4.01 mL at day 7 and 9.49 ± 3.95 and 9.52 ± 3.96 mL on day 14. Compared with pretreatment, hs-CRP and IL-6 levels and CSS score of the two groups decreased significantly following treatment (p < 0.05); the differences in the cerebral edema and hematoma volumes of the two groups on days 7 and 14 were not significant (p > 0.05). The hs-CRP and IL-6 levels and CSS scores of the treatment group decreased appreciably (p < 0.05), while the incidence of adverse reactions in the treatment and control groups was 16.67 and 13.33 %, respectively, but the difference was not significant (p > 0.05). Conclusion: Edaravone shows remarkable clinical efficacy and safety with no obvious adverse reactions in the treatment of ACH. Therefore, its use is recommended.

Medición de la profundidad anestésica y memoria durante anestesia general mediante el cerebral state monitor (csm x06)

Este es un ensayo clínico controlado realizado en 327 pacientes ASA II, sometidas a cesárea, distribuidas aleatoriamente en dos grupos iguales para identificar las variaciones hemodinámicas y nivel metamérico, al aplicar Anestesia Intratecal con Lidocaína Isobárica al 2(AILI) comparada con Lidocaína Hiperbárica al 5(AILH), ambas a dosis de 80 mg. Resultados: la AILI, se mantuvo en determinadas metámeras sin sustancial variabilidad, comportamiento totalmente contrario a la AILH. Las diferencias estadísticas en la presión sistólica, diastólica, y frecuencia cardiaca, entre ambos tipos de anestesia no fueron significativas. La hipotensión se presentó en 32,9con AILI, y 54con AILH; siendo tratada con 2,26 mg (ñ 3.65) y 3,93 mg (ñ 4,26) de efedrina respectivamente. (p> 0.05). Con AILI se presentaron 4 casos de bloqueo raquídeo alto más dificultad respiratoria y, con AILH 3 casos, de los cuales solo 2 presentaron dificultad respiratoria. Conclusión: la AILI produce un bloqueo nervioso más predecible que la AILH. Los valores hemodinámicos y la incidencia de complicaciones, entre ambos anestésicos fueron semejantes

Double stent-retriever technique in endovascular treatment of middle cerebral artery saddle embolus

Ischemic stroke is a major public health problem worldwide, considered as the third most costly health condition in developed countries, with urgent reperfusion remaining the paramount goal for its treatment. In line with the results of recent randomized control trials, the introduction of stent retrievers was a major advancement in the treatment of stroke; however, interventionalists sometimes encounter thrombi not-retrievable by applying conventional techniques. In this article, we present a case treated by an innovative double-stent retrieval in Y-configuration that may potentially help other clinicians in similar situations.

Cerebral responses to innocuous somatic pressure stimulation following aerobic exercise rehabilitation in chronic pain patients: a functional magnetic resonance imaging study

Objective: The purpose of this research was to assess the functional brain activity and perceptual rating of innocuous somatic pressure stimulation before and after exercise rehabilitation in patients with chronic pain.

Materials and methods: Eleven chronic pain patients and eight healthy pain-free controls completed 12 weeks of supervised aerobic exercise intervention. Perceptual rating of standardized somatic pressure stimulation (2 kg) on the right anterior mid-thigh and brain responses during functional magnetic resonance imaging (fMRI) were assessed at pre- and postexercise rehabilitation.

Results: There was a significant difference in the perceptual rating of innocuous somatic pressure stimulation between the chronic pain and control groups (P=0.02) but no difference following exercise rehabilitation. Whole brain voxel-wise analysis with correction for multiple comparisons revealed trends for differences in fMRI responses between the chronic pain and control groups in the superior temporal gyrus (chronic pain > control, corrected P=0.30), thalamus, and caudate (control > chronic, corrected P=0.23). Repeated measures of the regions of interest (5 mm radius) for blood oxygen level-dependent signal response revealed trend differences for superior temporal gyrus (P=0.06), thalamus (P=0.04), and caudate (P=0.21). Group-by-time interactions revealed trend differences in the caudate (P=0.10) and superior temporal gyrus (P=0.29).

Conclusion: Augmented perceptual and brain responses to innocuous somatic pressure stimulation were shown in the chronic pain group compared to the control group; however, 12-weeks of exercise rehabilitation did not significantly attenuate these responses.

Minimising impairment: protocol for a multicentre randomised controlled trial of upper limb orthoses for children with cerebral palsy

BACKGROUND: Upper limb orthoses are frequently prescribed for children with cerebral palsy (CP) who have muscle overactivity predominantly due to spasticity, with little evidence of long-term effectiveness. Clinical consensus is that orthoses help to preserve range of movement: nevertheless, they can be complex to construct, expensive, uncomfortable and require commitment from parents and children to wear. This protocol paper describes a randomised controlled trial to evaluate whether long-term use of rigid wrist/hand orthoses (WHO) in children with CP, combined with usual multidisciplinary care, can prevent or reduce musculoskeletal impairments, including muscle stiffness/tone and loss of movement range, compared to usual multidisciplinary care alone.

METHODS/DESIGN: This pragmatic, multicentre, assessor-blinded randomised controlled trial with economic analysis will recruit 194 children with CP, aged 5-15 years, who present with flexor muscle stiffness of the wrist and/or fingers/thumb (Modified Ashworth Scale score ≥1). Children, recruited from treatment centres in Victoria, New South Wales and Western Australia, will be randomised to groups (1:1 allocation) using concealed procedures. All children will receive care typically provided by their treating organisation. The treatment group will receive a custom-made serially adjustable rigid WHO, prescribed for 6 h nightly (or daily) to wear for 3 years. An application developed for mobile devices will monitor WHO wearing time and adverse events. The control group will not receive a WHO, and will cease wearing one if previously prescribed. Outcomes will be measured 6 monthly over a period of 3 years. The primary outcome is passive range of wrist extension, measured with fingers extended using a goniometer at 3 years. Secondary outcomes include muscle stiffness, spasticity, pain, grip strength and hand deformity. Activity, participation, quality of life, cost and cost-effectiveness will also be assessed.

DISCUSSION: This study will provide evidence to inform clinicians, services, funding agencies and parents/carers of children with CP whether the provision of a rigid WHO to reduce upper limb impairment, in combination with usual multidisciplinary care, is worth the effort and costs.

Communication changes experienced by adults with cerebral palsy as they age

PURPOSE: Adults with cerebral palsy (CP) experience multiple, functional changes as they age, including changes to communication modes and methods that enable development and maintenance of relationships, communicative participation and quality-of-life. Little is known about the nature of communication changes experienced by this group. The aim of this study was to better understand how adults with CP experience changes in their communication abilities as they age and the subsequent psychosocial impact.

METHOD: Twenty adults with cerebral palsy aged 40-72 years with complex communication needs (CCN) participated in a series of in-depth interviews, framing their experiences of loss and grief throughout their lives. The impact of changing communication abilities emerged as an important area of focus. Data were analysed using constructivist grounded theory methodology.

RESULT: Themes arising from the participants' perceptions of their communication included experiencing communication change as a loss with subsequent impact on self-concept; and how communication is integral to the process of managing losses associated with older age.

CONCLUSION: Implications for speech-language pathologists working with older people with cerebral palsy and CCN include the need to understand the psychosocial impact of communication changes on social interaction, relationships and communicative participation. It is important to promote positive and meaningful communication options that maintain a coherent sense of self in addition to promoting functional communication skills and communicative participation.
