Título: Environmental enrichment restores cognitive deficits induced by experimental childhood meningitis
Fonte: Rev. bras. psiquiatr;36(4):329-329, Oct-Dec/2014. graf.
Idioma: en.
Resumo: Objective: To evaluate the influence of environmental enrichment (EE) on memory, cytokines, and brain-derived neurotrophic factor (BDNF) in the brain of adult rats subjected to experimental pneumococcal meningitis during infancy. Methods: On postnatal day 11, the animals received either artificial cerebrospinal fluid (CSF) or Streptococcus pneumoniae suspension intracisternally at 1 × 106 CFU/mL and remained with their mothers until age 21 days. Animals were divided into the following groups: control, control + EE, meningitis, and meningitis + EE. EE began at 21 days and continued until 60 days of age (adulthood). EE consisted of a large cage with three floors, ramps, running wheels, and objects of different shapes and textures. At 60 days, animals were randomized and subjected to habituation to the open-field task and the step-down inhibitory avoidance task. After the tasks, the hippocampus and CSF were isolated for analysis. Results: The meningitis group showed no difference in performance between training and test sessions of the open-field task, suggesting habituation memory impairment; in the meningitis + EE group, performance was significantly different, showing preservation of habituation memory. In the step-down inhibitory avoidance task, there were no differences in behavior between training and test sessions in the meningitis group, showing aversive memory impairment; conversely, differences were observed in the meningitis + EE group, demonstrating aversive memory preservation. In the two meningitis groups, IL-4, IL-10, and BDNF levels were increased in the hippocampus, and BDNF levels in the CSF. Conclusions: The data presented suggest that EE, a non-invasive therapy, enables recovery from memory deficits caused by neonatal meningitis. .(AU)

Título: Etmoiditis complicada con celulitis orbitaria en un lactante / Complicated ethmoiditis with orbital cellulitis in a nursling
Fonte: Rev. cuba. pediatr;86(4):521-528, oct.-dic. 2014.
Idioma: es.
Resumo: Se define la etmoiditis como la inflamación e infección de la mucosa de las celdas etmoidales. Se diagnostica clínicamente con la presencia de edema en el ángulo medial del ojo, que se extiende a las estructuras adyacentes. Estudios imagenológicos son necesarios para verificar la presencia de complicaciones, entre las que se citan el absceso orbitario, subperióstico, epidural, subdural, cerebral, tromboflebitis del seno cavernoso, meningoencefalitis y la muerte del paciente. Streptococcus pneumoniae, Staphylococcus aureus y Haemophilus influenzae son microorganismos frecuentemente responsables de este cuadro. Las complicaciones orbitarias en las etmoiditis, necesitan el diagnóstico y tratamiento precoz para evitar secuelas irreversibles. Se presenta el caso de un lactante masculino, de 1 mes y 26 días de nacido, que ingresa con fiebre, rinorrea serosa y rechazo al alimento. Evolutivamente se constata marcada obstrucción nasal, edema periorbitario izquierdo, rubor, calor, protrusión del globo ocular e irritabilidad, y se diagnostica etmoiditis complicada con celulitis orbitaria. Se realiza tomografía axial computarizada que informa seno etmoidal izquierdo ocupado por contenido de densidad líquida con celularidad (15-25 UH), engrosamiento de partes blandas de la pared interna de la órbita que abomba, comprime y desplaza la musculatura orbitaria, y se extiende al párpado y al ala izquierda de la nariz desviando tabique blando; así como ligera proptosis, y disminución de la densidad ósea de la pared interna de la cavidad orbitaria. Se toma muestra para cultivo y se aísla Staphylococcus aureus meticillin resistente. Se comentan los elementos diagnósticos y su tratamiento, con el objetivo de llamar la atención de los pediatras para lograr el diagnóstico y tratamiento oportuno.(AU)

Ethmoiditis is the inflammation and infection of the ethmoidal cell mucus. It is clinically diagnosed after observing edema in the medial angle of the eye extending into the adjacent structures. Imaging studies are required to verify complications such as orbital, subperiostic, epidural, subdural, cerebral abscess; thrombophlebitis of the cavernous sinus, meningoencephalitis and finally death of the patient. Streptococcus pneumoniae, Staphylococcus aureus and Haemophilus influenzae are frequently responsible for this health picture. The orbital complications seen in ethmoiditis require early diagnosis and treatment to avoid irreversible sequelae. This is the case of a male nursling aged one month and 26 days, who was admitted to the hospital with fever, rhinorrea serosa and rejection to feeding. As his condition progresses, it was observed that he presented with marked nasal obstruction, left periorbital edema, blushing, heat, eyeball protusion and irritability. He was finally diagnosed as complicated ethmoiditis with orbital cellulitis case. Computer axial tomography revealed left ethmoidal sinus filled with fluid content having cellularity rate of 15-25 UH, thickening of soft parts of the internal wall of the orbit that juts out, compresses and shifts the orbital musculature and extends into the eyebrow and to the left wing of the nose, thus deviating the soft septum in addition to slight proptosis and reduction of the bone density of the internal wall of the orbital cavity. A sample was taken for culturing, which resulted in isolation of methicillin-resistant Staphylococcus aureus. The diagnostic elements and the treatment of this disease were explained in order to call the pediatricians´attention to timely diagnose and treat these patients.(AU)

Título: Interleuquina-6 y factor de necrosis tumoral-α en el suero y líquido cefalorraquídeo de niños con meningoencefalitis viral / Interleukin-6 and tumor necrosis factor-α in serum and cerebrospinal fluid from children with viral meningoencephalitis
Fonte: Rev. cuba. pediatr;86(4):445-453, oct.-dic. 2014.
Idioma: es.
Resumo: Introducción: las meningoencefalitis virales en el niño son causadas con mayor frecuencia por enterovirus, y tienen un curso generalmente benigno y autolimitado. Objetivo: estimar las concentraciones de interleuquina-6 y factor de necrosis tumoral-α en suero y líquido cefalorraquídeo de niños con meningoencefalitis viral. Métodos: se realizó un estudio descriptivo y transversal. Se estudiaron 61 pacientes, con edades entre 1 mes y 17 años con diagnóstico de meningoencefalitis viral por cuadro clínico, estudio citoquímico de líquido cefalorraquídeo y detección de genoma viral de enterovirus por reverso trascripción y reacción en cadena de la polimerasa. Se determinaron concentraciones de interleuquina-6 y factor de necrosis tumoral-α en 48 muestras de suero y 35 de líquido cefalorraquídeo. Para el análisis estadístico se empleó, la prueba de Wilcoxon para 2 muestras relacionadas, y la de Spearman para correlacionar las concentraciones de citoquinas. Resultados: se detectó genoma viral en 3 muestras de líquido cefalorraquídeo con celularidad aumentada y predominio de polimorfonucleares, y en 3 muestras con celularidad normal. La cuantificación de interleuquina-6 en suero, fue 91,6 ± 39,0 pg/mL; y de factor de necrosis tumoral-α 106,5 ± 54,6 pg/mL. En el líquido cefalorraquídeo la cuantificación de interleuquina-6 fue de 109,65 ± 49,6 pg/mL, y de factor de necrosis tumoral-α 75,28 ± 29,9 pg/mL. Conclusiones: se determinaron concentraciones elevadas de interleuquina-6 y de factor de necrosis tumoral-α en todas las muestras estudiadas. Este último se detectó más elevado en el suero, mientras la interleuquina-6 se elevó más en el líquido cefalorraquídeo, y se correlacionó positivamente con sus valores en suero y con los del factor de necrosis tumoral-α.(AU)

Introduction: viral meningoencephalitis affecting the child is caused mainly by enteroviruses and have generally self-limited benign course. Objective: to estimate the interleukin-6 and tumor necrosis factor-α present in the serum and the cerebrospinal fluid of children suffering viral meningoencephalitis. Method: cross-sectional descriptive study of 61 patients aged one month to 17 years and diagnosed with viral meningoencephalitis. The diagnosis was based on their clinical picture, the cytochemical study of their cerebrospinal fluid and the detection of enterovirus viral genome through the reverse transcriptase polymerase chain reaction. Forty eight serum samples and 35 cerebrospinal fluid samples served to determine the interleukin-6 and tumor necrosis factor-α concentrations. The statistical analysis included Wilcoxon's test for 2 related samples and the Spearman's test for correlating cytokine concentrations. Results: viral genome was detected in 3 cerebrospinal fluid samples with increased cellularity and predominant polymorphonuclear neutrophils and in other 3 samples with normal cellularity. The quantitation of serum interleukin-6 and of tumor necrosis factor-alpha were 91.6 ± 39.0 pg/mL and 106.5 ± 54.6 pg/mL, respectively. The interleukin-6 and tumor necrosis factor-alpha levels in the cerebrospinal fluid amounted to 109.65 ± 49.6 pg/mL, and 75.28 ± 29.9 pg/mL, respectively. Conclusions: high interleukin-6 and tumor necrosis factor-alpha levels were found in all the studied samples. The factor concentrations were higher in the serum whereas those of interleukin-6 were higher in the cerebrospinal fluid; there was positive correlation between interleukin-6 values in the serum and those of the tumor necrosis factor-alpha.(AU)

Título: Ocorrência de resultados falso-negativos na reação de PCR em Tempo Real (PCR-TR) no diagnóstico da doença meningocócica / False-negative results in Real-Time PCR (RT-PCR) formeningococcal disease diagnosis
Fonte: Rev. Inst. Adolfo Lutz;72(1):65-71, 2013. tab.
Idioma: en.
Resumo: Factors responsible for false-negative results (F-N) in RT-PCR assay for detecting N. meningitidis in serumand CSF samples were investigated. As the meningococcal disease should be rapidly treated because ofits high mortality and epidemic potential, the F-N in diagnostic testing may cause treatment failuresand/or on disease restraint in community. Thus, it is crucial to learn the factors which cause F-N in RTPCRassays. The F-N were induced by inhibition, low quantity of target DNA in extracted samples, andinadequate temperature employed at PCR annealing procedure. As bacterial DNA concentration in samplesmight be highly variable, the ideal sample volume to be extracted could not be defined. As previouslyrecommended for N. meningitidis gene-grouping by RT-PCR assay, the annealing temperature at 60 °Cwas not suitable for B and W135 genogroups. Altogether, these factors induced F-N in 31 samples; therefore,30 % of N. meningitidis detected by RT-PCR were classified as non-genogrouped. The inhibitors and/orthe low amount of target DNA induced F-N on RT-PCR, independently of the specimen volume used forextracting DNA. However, adjustments on the PCR annealing temperature and amount of extracted DNAadded into the reaction might avoid the occurrence of the majority of F-N.(AU)

Título: Avaliação de resultados discrepantes obtidos na execução de PCR em tempo real em amostras de pacientes com suspeita clínica de meningite bacteriana / Inconsistent results in real-time PCR in analyzing samples from patients with suspected bacterial meningitis
Fonte: Rev. Inst. Adolfo Lutz;72(2):161-164, 2013. tab.
Idioma: pt.
Resumo: O princípio básico para obter resultado confiável é a compatibilidade entre as réplicas e suareprodutibilidade. Na rotina diagnóstica por PCR em tempo real (PCR-TR), em que centenas de amostrassão processadas, a obtenção de resultados com Cts tardios ou réplicas que diferem entre si por mais de trêsunidades, são inevitáveis. Das 3.000 amostras processadas em 2010, em duplicata, na rotina diagnósticadas meningites bacterianas por PCR-TR na pesquisa de N. meningitidis, S. pneumoniae e H. influenzae,157 (5,2 %), apresentaram inconsistência entre as réplicas (diferença entre Cts maior do que 3) e/ou altosvalores de Cts; e os ensaios foram retestados. O presente trabalho investigou estes resultados obtidos, osbenefícios destas repetições e as possíveis razões da ocorrência dos resultados discrepantes. Verificouseque, apenas 18 (11 %) das amostras submetidas à repetição, apresentaram resultados positivos. Erroshumanos inerentes à pipetagem, como o uso de pipetas não calibradas, a baixa concentração de DNAalvo nas amostras, a degradação da sonda ou mesmo a possível contaminação aleatória são fatores quecontribuem para induzir resultados discrepantes. A realização do ensaio de PCR-TR com amostras emduplicata e a repetição de ensaios com resultados discordantes é um artifício eficiente para avaliar e definirestes resultados.(AU)

Título: Evolution of Minimally Invasive Approaches to the Sella and Parasellar Region
Fonte: Int. arch. otorhinolaryngol. (Impr.);18(supl.2):148-148, Apr-Jun/2014. graf.
Idioma: en.
Resumo: Introduction Given advancements in endoscopic image quality, instrumentation, surgical navigation, skull base closure techniques, and anatomical understanding, the endonasal endoscopic approach has rapidly evolved into a widely utilized technique for removal of sellar and parasellar tumors. Although pituitary adenomas and Rathke cleft cysts constitute the majority of lesions removed via this route, craniopharyngiomas, clival chordomas, parasellar meningiomas, and other lesions are increasingly removed using this approach. Paralleling the evolution of the endonasal route to the parasellar region, the supraorbital eyebrow craniotomy has also been increasingly used as an alternative minimally invasive approach to reach this skull base region. Similar to the endonasal route, the supraorbital route has been greatly facilitated by advances in endoscopy, along with development of more refined, low-profile instrumentation and surgical navigation technology. Objectives This review, encompassing both transcranial and transsphenoidal routes, will recount the high points and advances that have made minimally invasive approaches to the sellar region possible, the evolution of these approaches, and their relative indications and technical nuances. Data Synthesis The literature is reviewed regarding the evolution of surgical approaches to the sellar region beginning with the earliest attempts and emphasizing technological advances, which have allowed the evolution of the modern technique. The surgical techniques for both endoscopic transsphenoidal and supraorbital approaches are described in detail. The relative indications for each approach are highlighted using case illustrations. Conclusions Although tremendous advances have been made in transitioning toward minimally invasive transcranial and transsphenoidal approaches to the sella, further work remains to be done. Together, the endonasal endoscopic and the supraorbital endoscope-assisted ...(AU)

Idioma: es.
Resumo: We report a 57-year-old woman who presented with low back pain, fever and impairment of consciousness. The patient was admitted to the intensive care unit in Glasgow 8, with neck stiffness, peritoneal irritation, leukocytosis, hyperglycemia requiring insulin and a urine test suspecting an infection. Brain CT was unremarkable, while CT of the abdomen and pelvis evidenced emphysematous cystitis, retropneumoperitoneum and pneumorrhachis. Blood, urine and cerebrospinal fluid cultures were positive to Escherichia coli. She was treated with ceftriaxone, ciprofloxacin and amikacin during one month followed by ciprofloxacin until completing 100 days. The air in the spinal canal and bladder decreased. However she suffered several infectious complications such as multiple paravertebral, epidural and psoas abscesses, L5-S1 spondylitis and a L3 fracture. As an inflammatory complication she developed a bulbar infarction and tetraparesis. She had a good clinical response with medical treatment, partial improvement of the paresis and reduction of epidural abscesses.(AU)

Título: Meningioma cordóide da região pineal / Pineal region chordoid meningioma
Fonte: J. bras. neurocir;24(2):148-152, 2013.
Idioma: pt.
Resumo: Objetivo: Meningiomas correspondem a apenas 8% dos tumores da região pineal. O meningioma cordóide (CM) representa0,5 a 1,0% de todos os meningiomas intracranianos, sendo ainda mais raro na região pineal. Na literatura, apenas seis casosde CMs são relatados. Apresentação clínica: Descrevemos o caso de um paciente com cefaleia, confusão mental, disartria eataxia de marcha. O exame oftalmológico revelou paresia do olhar vertical e dissociação do reflexo pupilar fotomotor e deconvergência. A RM revelou uma lesão expansiva na região da pineal com impregnação heterogênea pelo contraste. O tumorfoi totalmente ressecado pela abordagem occipital transtentorial lateral em posição três-quartos prona. A análise histológicarevelou um CM. Conclusão: Meningioma cordóide é uma variante rara de meningioma pouco descrita na região pineal, masque deve ser considerada como diagnóstico diferencial das patologias localizadas nessa região. Este estudo contribui para ummelhor entendimento do diagnostico e manejo destes tumores. (AU)
