RESUMO

ABSTRACT Normal pressure hydrocephalus (NPH) has been a topic of debate since its introduction in publications. More frequent in the elderly population, it is characterized by gait disturbance, urinary urge incontinence and cognitive decline. Therefore, it is a clinical-radiological entity with relatively common findings for the age group, which together may have greater specificity. Therefore, its diagnosis must be careful for an adequate selection of patients for treatment with ventricular shunt, since the symptoms are potentially reversible. The tap test has a high positive predictive value as a predictor of therapeutic response, but a negative test does not exclude the possibility of treatment. Scientific efforts in recent years have been directed towards a better understanding of NPH and this narrative review aims to compile recent data from the literature in a didactic way for clinical practice.

RESUMO A hidrocefalia de pressão normal (HPN) é tema de debate desde sua introdução na literatura. Mais frequente na população idosa, caracteriza-se por distúrbio de marcha, urge-incontinência urinária e declínio cognitivo. Portanto, trata-se de uma entidade clínico-radiológica com achados relativamente comuns para a faixa etária, que em conjunto, podem ter maior especificidade. Sendo assim, seu diagnóstico deve ser criterioso para uma adequada seleção de pacientes para tratamento com a derivação ventricular, uma vez que os sintomas são potencialmente reversíveis. O tap test possui valor preditivo positivo alto preditor de resposta terapêutica, mas um teste negativo não exclui a possibilidade de tratamento. Esforços científicos nos últimos anos têm sido direcionados para melhor entendimento da HPN e essa revisão narrativa se propõe a compilar dados recentes da literatura de forma didática para a prática clínica.

RESUMO

Central nervous system infections are a medical emergency, due to their high fatality and sequelae. Timely treatment is essential, and should be initially indicated empirically by clinical guidance, without microbiological certainty. Hence the importance of cerebrospinal fluid (CSF) analysis as an etiological and therapeutic guide in the crucial initial hours of management. We report a 57-year-old woman consulting for fever and altered mental status. A brain CAT scan was normal. A lumbar puncture disclosed a CSF with predominance of neutrophils. Suspecting a bacterial meningitis, antimicrobial treatment was started but 48 hours after, the patient did not improve. A new lumbar puncture disclosed a CSF with predominance of lymphocytes. The lymphocyte shift prompted a PCR that was positive for herpes virus. The patient was treated with acyclovir with a good evolution.

RESUMO

Los avances en la tecnología de la ciencia biomédica han permitido incrementar la tasa de éxito de las intervenciones gracias a las mejoras en seguridad y eficacia. Durante la evaluación del paciente con un trastorno neurológico agudo que requiere una punción lumbar, existen algunas condiciones que pueden dificultar la realización de este procedimiento, tales como la infección en el lugar de la punción o las anomalías óseas que puedan causar una lesión medular. El uso de la ecografía a pie de cama es una buena alternativa para acompañar a la punción debido a su capacidad para explorar estructuras que no pueden ser evaluadas mediante la exploración física. En los centros hospitalarios de baja complejidad, donde pueden existir barreras de acceso a herramientas de imagen costosas, la ecografía es una opción rentable para el abordaje de patologías urgentes. Con base en lo anterior, el objetivo de este manuscrito consiste en revisar conceptos relevantes basados en la evidencia más reciente, que están relacionados con el uso de la ecografía para la realización de la punción lumbar.

Advances in biomedical technology have increased the success rate of medical procedures due to improvements in safety and efficacy. During the assessment of patients with acute neurological disorder who require a lumbar puncture, some conditions may hinder its performance, such as infection at the puncture site or bone abnormalities that may cause spinal cord injury. Bedside ultrasound is a good alternative to assist in the performance of a puncture, due to its ability to examine structures that cannot be assessed by physical examination. In primary health care centers, where there may be obstacles that prevent access to expensive imaging tools, ultrasound is a cost-effective option in the approach to urgent pathologies. In view of the foregoing, this paper aims to review important recent evidence-based concepts related to the use of ultrasound for the performance of a lumbar puncture.

RESUMO

ABSTRACT Background: Intrathecal chemotherapy is a local therapeutic modality used for treatment of leptomeningeal metastases. However, the techniques currently used, i.e. repeated lumbar puncture and Ommaya reservoir, have certain disadvantages. Lumbar intrathecal port (LIP) placement is a relatively novel technique, which has been used for pain management in cancer patients. Objective: To investigate the use of LIP for intrathecal administration of chemotherapeutic agents in patients with leptomeningeal metastases. Methods: Retrospective study of 13 patients treated with intrathecal chemotherapy for secondary leptomeningeal involvement of a primary solid tumor were included in this retrospective study. The patients received intrathecal chemotherapy through a LIP. Results: The patients received a total of 123 intrathecal chemotherapy doses. No grade 3-4 toxicity, technical problem or severe complication developed. During a median of 136 days of follow-up (range, 67-376 days), 12 patients died (92.3%). The treatment resulted in symptom improvement in all patients and self-rated overall health and quality of life improved, compared with baseline. Conclusions: The LIP system, which has been used for intrathecal pain management for decades, appears to offer a safe alternative for intrathecal chemotherapy in patients with leptomeningeal metastases. Further studies are warranted to clarify its potential use in this setting.

RESUMEN Antecedentes: La quimioterapia intratecal es una modalidad terapéutica local utilizada para el tratamiento de metástasis leptomeníngeas. Sin embargo, las técnicas empleadas actualmente, es decir, las punciones lumbares repetidas y el depósito de Ommaya, tienen algunos inconvenientes. La colocación de un puerto intratecal lumbar (LIP) es una técnica relativamente nueva que se ha utilizado para el tratamiento del dolor en pacientes con cáncer. Objetivo: Investigar el uso de LIP para la administración intratecal de agentes quimioterapéuticos en pacientes con metástasis leptomeníngeas. Métodos: Este estudio retrospectivo incluyó un total de 13 pacientes tratados con quimioterapia intratecal por afectación leptomeníngea secundaria de un tumor sólido primario. Los pacientes recibieron quimioterapia intratecal a través de un LIP. Resultados: Los pacientes recibieron un total de 123 dosis de quimioterapia intratecal. No se desarrolló toxicidad de grado 3-4, ni se presentaron problemas técnicos o complicaciones graves. Durante un promedio de 136 días de seguimiento (rango, 67-376 días), murieron 12 pacientes (92,3 %). El tratamiento dio como resultado una mejoría de los síntomas en todos los pacientes. La salud general autoevaluada y la calidad de vida mejoraron en comparación con los valores iniciales. Conclusiones: El sistema LIP que se ha utilizado para el manejo del dolor intratecal durante décadas, parece ofrecer una alternativa segura para la quimioterapia intratecal en pacientes con metástasis leptomeníngeas. Serán necesarios más estudios para determinar su uso potencial en este ámbito.

RESUMO

ABSTRACT Background: Spinal muscular atrophy (SMA) is a neurodegenerative disease of lower motor neurons associated with frequent occurrence of spinal deformity. Nusinersen is an antisense oligonucleotide that increases SMN protein level and is administrated by frequent intrathecal lumbar injections. Thus, spinal deformities and previous spinal surgery are important challenges for drug delivery in SMA. Objective: To report imaging methods used for Nusinersen injection in SMA patients. Methods: Nusinersen injection procedures in SMA types 2 and 3 patients who had previous spinal surgery were analyzed retrospectively to describe the imaging and puncture procedures, as well as the occurrence of complications. Results: Nine SMA patients (14 to 50 years old) underwent 57 lumbar punctures for nusinersen injection. Six patients had no interlaminar space available; in five of them, a transforaminal approach was used, and another one underwent a surgery to open a posterior bone window for the injections. Transforaminal puncture was performed using CT scan in three cases and fluoroscopy in the other two, with a similar success rate. One patient in the transforaminal group had post-procedure radiculitis, and another one had vagal reaction (hypotension). In three cases, with preserved interlaminar space, injections were performed by posterior interlaminar puncture, and only one adverse event was reported (post-puncture headache). Conclusion: In SMA patients with previous spinal surgery, the use of imaging-guided intervention is necessary for administering intrathecal nusinersen. Transforaminal technique is indicated in patients for whom the interlaminar space is not available, and injections should always be guided by either CT or fluoroscopy.

RESUMO Introdução: A atrofia muscular espinal (AME) é uma desordem neurodegenerativa dos motoneurônios inferiores frequentemente associada à ocorrência de deformidade da coluna vertebral. Nusinersena é um oligonucleotídeo antisense que aumenta os níveis da proteína SMN, sendo administrado através de injeções lombares intratecais frequentes. Assim, deformidades da coluna vertebral e abordagem cirúrgica prévia são desafios importantes para a administração de medicamentos na AME. Objetivo: descrever os métodos de imagens utilizados para administração do Nusinersena nos pacientes com AME. Métodos: Os procedimentos de administração de nusinersena em pacientes com AME dos tipos 2 e 3 submetidos à cirurgia prévia da coluna foram analisados retrospectivamente para descrever os métodos de imagem e punção, e a ocorrência de complicações. Resultados: Nove pacientes com AME (14 a 50 anos) foram submetidos a 57 punções lombares para administração de nusinersena. Seis pacientes tinham enxerto ósseo ou nenhum espaço interlaminar disponível; em cinco deles foi utilizada uma abordagem transforaminal, e outra paciente foi submetida à abertura cirúrgica de janela óssea para as injeções. A punção transforaminal foi realizada usando tomografia computadorizada (TC) em três casos e fluoroscopia nos outros dois, com taxa de sucesso semelhante. Um paciente no grupo de abordagem transforaminal apresentou radiculite pós-procedimento e outro apresentou reação vagal (hipotensão). Em três casos, com espaço interlaminar preservado, foram realizadas técnica de punção interlaminar posterior e apenas um evento adverso foi relatado (cefaleia pós-punção). Conclusão: Em pacientes com AME e cirurgia prévia, o uso de intervenção guiada por imagem é necessário para a administração de nusinersena. A técnica transforaminal é indicada nos casos onde o espaço interlaminar não está disponível, devendo ser guiada por TC ou técnicas de imagem fluoroscópica.

RESUMO

INTRODUCTION: Normotensive hydrocephalus is a differential diagnosis in the evaluation of the dementia syndrome. The diagnostic protocols would allow detecting this pathology that has more effective treatment than other dementias. OBJECTIVE: To describe a population with clinical suspicion of normal pressure hydrocephalus evaluated in a Colombian psychiatric hospital and discuss the possible reasons for its diagnostic and therapeutic delay. MATERIALS AND METHODS: We conducted a retrospective study of medical records to identify patients with suspected normal pressure hydrocephalus during a 5-year period. RESULTS: Thirty-five patients with suspected normal pressure hydrocephalus underwent diagnostic lumbar puncture and five of them were considered candidates for a peritonealvenous shunt, but none underwent this surgical procedure. After three to six months of the lumbar puncture, the gait pattern improved in 22.8% of the patients, cognition in 22.8%, and sphincter control in 11.4%. Improvement was not sustained in the long term (1 year) in any of them. CONCLUSION: This study suggests the poor implementation of the protocols for evaluating patients with cognitive deficits and delays in the diagnosis of normal pressure hydrocephalus. A small number of patients were identified as candidates for treatment. Normal pressure hydrocephalus is a potentially reversible clinical entity with the placement of a peritoneal ventricular shunt, but delays in diagnosis and treatment have deleterious consequences for patients and their families.

RESUMO

Abstract Background: Post-dural puncture headache (PDPH) is an iatrogenic condition following lumbar puncture (LP). Incidence is variable and often associated with young females. Technical features of the procedure (i.e. needle gauge) have been investigated; however there is no investigation on the method of cerebrospinal fluid (CSF) collection. Objective: To investigate whether mild CSF aspiration is associated with increased PDPH in selected patients. Methods: 336 subjects were eligible to the study. Data on 237 patients from a tertiary neurology hospital who underwent diagnostic LP from February 2010 to December 2012 were analysed. Patient demographics, lumbar puncture method, CSF biochemical characteristics, opening pressures, and a follow-up inquire on PDPH occurrence were collected. CSF was collected either by allowing free flow or by mild aspiration. Results: The aspiration arm (n=163) was comprised of 55.8% females with mean age of 52(35‒69) years. Sex distribution was not different between the two arms (p=0.191). A significant larger amount of CSF was obtained in the aspiration arm (p=0.011). The incidence of PDPH in the aspiration arm was 16.5% versus 20.2% in the free flow arm, not statistically significant (p=0.489). No relevant associations emerged from the analyses in the subgroup aged <65 years. Conclusions: Aspiration of the CSF during LP was not associated with increased rates of PDPH compared to the standard method, particularly when larger amounts of CSF are required and ideal conditions are met. This is the first study looking into this matter, aiming to add safety to the procedure. Further randomized trials are required.

Resumo Introdução: Cefaleia pós-punção dural (CPPD) é uma condição iatrogênica após punção lombar (LP). Incidência é variável; frequentemente associada a mulheres jovens. Características técnicas do procedimento (ex: calibre da agulha) foram investigadas; no entanto, não há investigação sobre o método de coleta do líquido cefalorraquidiano (LCR). Objetivo: Avaliar se aspiração leve do LCR está associada ao aumento da CPPD em pacientes selecionados. Métodos: 336 indivíduos foram elegíveis para o estudo. Dados de 237 pacientes em um hospital neurológico terciário que foram submetidos à PL diagnóstica de fevereiro de 2010 a dezembro de 2012 foram analisados. Coletamos dados demográficos dos pacientes, método da PL, características bioquímicas do LCR, pressões de abertura e ocorrência da CPPD. Todos as PLs ocorreram em decúbito lateral. O LCR foi coletado permitindo livre fluxo ou aspiração leve. Resultados: O grupo aspiração (n=163) apresentava 55,8% de mulheres, idade média de 52(35‒69) anos. A distribuição por sexo não foi diferente entre os dois grupos (p=0,191). Uma quantidade maior de LCR foi obtida no grupo aspiração (p=0,011). A incidência de CPPD no grupo de aspiração foi de 16,5% versus 20,2% no fluxo livre, não estatisticamente significante (p=0,489). Nenhuma associação emergiu das análises no subgrupo com idades <65 anos. Conclusões: A aspiração do LCR durante PL não está associada ao aumento da CPPD em comparação com a método padrão, particularmente quando quantidades maiores de LCR são necessárias e condições ideais são satisfeitas. Este é o primeiro estudo a investigar o topico, visando aumentar a segurança do procedimento. Necessita-se futuros estudos randomizados.

RESUMO

ABSTRACT This article is based on a historical review of the medical literature with the purpose of acknowledging the historical stages and anatomical findings over the years, which led gradually to performance of the first lumbar puncture by Quincke, as well as collection techniques and analyses, allowing it to be an irreplaceable diagnostic tool in daily clinical practice. Cerebrospinal fluid analyses have continued to develop and nowadays play a major role in diagnosing and understanding the physiopathology of a great variety of neurological conditions. Biomarkers and genetic sequencing have recently been the target of multiple studies and are implicated as promising diagnostic tools of a large range of diseases.

RESUMEN Este artículo se basa en una revisión histórica de la literatura médica cuyo objetivo fue reconocer las fases y los hallazgos anatómicos a lo largo de los años que condujo gradualmente a la primera punción lumbar por Quincke, así como las técnicas y los análisis de recolección; esa punción se ha convertido en una herramienta insustituible de diagnóstico en la práctica clínica diaria. Los análisis del líquido cefalorraquídeo se desarrollaron y hoy tienen un papel importante en el diagnóstico y en la comprensión de la fisiopatología de varias condiciones neurológicas. Recientemente, los biomarcadores y la secuenciación genética fueron objeto de varios estudios y son considerados técnicas de diagnóstico prometedoras para muchas enfermedades.

RESUMO

INTRODUCTION: The presence of an active bacteremia has been considered a relative contraindication to perform an intrathecal puncture due to the risk of causing meningitis or epidural abscess. However, a clear and definite causal relationship has not yet been demonstrated. OBJECTIVES: To determine the relationship between intrathecal puncture and the development of meningitis in sub-jects with bacteremia. MATERIALS AND METHODS: Experimental study in rats with chronic bacteremia to which dural puncture was performed. Meningitis was then evaluated by direct drainage of the cisterna magna and histopathological studies of brain tissue. RESULTS AND CONCLUSION: 12 of 40 bacteremic rats that underwent intrathecal puncture developed meningitis. Previous administration of antibiotics seems to reduce this risk.

INTRODUCCIÓN: Se ha considerado la presencia de una bacteremia activa como contraindicación relativa para realizar una punción intratecal por el riesgo de provocar meningitis o absceso peridural. Sin embargo, aún no se ha podido demostrar una relación causal clara y definida. OBJETIVOS: Determinar la relación entre punción intratecal y el desarrollo de meningitis en sujetos con bacteremia. MATERIALES Y MÉTODOS: Estudio experimental en ratas con bacteremia crónica a las que se les realizó punción dural, luego se evaluó la presencia o no de meningitis mediante drenaje directo de la cisterna magna y estudios histopatológicos de tejido cerebral. RESULTADOS Y CONCLUSIÓN: 12 de 40 ratas bacterémicas a las que se le realizó punción intratecal desarrollaron meningitis. La adminis-tración previa de antibiótico parece disminuir este riesgo.

RESUMO

La neurocisticercosis es una enfermedad frecuente, su principal ubicación es en el parénquima cerebral; sin embargo, menos del 5% de los casos son de ubicación espinal donde producen cuadros clínicos pseudotumorales u obstructivos. Presentamos el caso de un paciente que ingresa por cefalea crónica con signos de hipertensión endrocraneana, sin clínica medular, y en quien se obtuvo durante el estudio de punción lumbar una membrana cisticercótica y líquido cefalorraquídeo con gran consumo de glucosa (3mg/dL). El hallazgo de un cisticerco de ubicación intradural-extramedular durante una punción lumbar es un hallazgo muy raro, solo descrito en pacientes con clínica evidente. Recomendamos sospecharla cuando no haya evidencia clínica de compromiso medular pero se tenga sugerencia de cisticercosis cerebral y líquido cefalorraquídeo alterado, ampliando el estudio con neuroimágenes.

Neurocysticercosis is a frequent disease, its main location is in the brain parenchyma; however, less than 5% of cases are of spinal location where they produce pseudotumoral or obstructive clinical manifestations. We present the case of a patient admitted due to chronic headache with signs of endrocranial hypertension, without clinical symptoms, and in whom a cysticercotic membrane and cerebrospinal fluid with high glucose consumption (3mg/dL) was obtained during the lumbar puncture study. The finding of a cysticercus of intradural-extramedullary location, during a lumbar puncture is a very rare finding, only described in patients with evident clinical signs. We recommend suspecting it when there is no clinical evidence of spinal cord involvement but there is a suggestion of cerebral cysticercosis and altered cerebrospinal fluid, expanding the study with neuroimaging.

RESUMO

RESUMEN OBJETIVOS: Describir las características clínicas y paraclínicas de niños entre 3 meses y 14 años diagnosticados con meningitis bacteriana aguda. Describir los hallazgos de neuroimágenes, especificar los gérmenes aislados en los pacientes y su patrón de susceptibilidad por antibiograma. Evidenciar las complicaciones neurológicas al egreso y documentar la frecuencia de la mortalidad que presentan los pacientes hospitalizados por meningitis bacteriana aguda (MBA) en el Hospital Universitario San Vicente Fundación (HUSVF). MATERIALES Y MÉTODOS: Estudio de tipo descriptivo, retrospectivo. Se incluyeron los registros de pacientes con diagnóstico al egreso hospitalario de MBA desde el 1 de enero de 2011 al 31 de diciembre de 2015. Los datos fueron tomados de las historias clínicas de pacientes del Hospital Infantil del HUSVF. Los pacientes admitidos fueron aquellos niños entre 3 meses y 14 años con diagnóstico clínico de meningitis bacteriana aguda con LCR alterado y que cumplieran con uno o más de los siguientes requisitos: hemocultivos positivos, látex positivo, aislamiento en cultivo LCR, o clínica y evolución característica de MBA. Se extrajo información demográfica, manifestaciones clínicas al ingreso hospitalario y los hallazgos en los exámenes de laboratorio así como la presencia de complicaciones durante la estancia hospitalaria. Se utilizó el programa estadístico SPSS IBM statistics 23,0. RESULTADOS: Se incluyeron en el estudio 44 pacientes con un promedio de edad de 63,7 meses (56,4 DE). Predominó el sexo masculino con 27 niños (61,4 %). La mayoría de los pacientes residían en el departamento de Antioquia 86,4%. Los síntomas más frecuentes fueron: fiebre en el 77,3 %, alteración del estado de conciencia en el 77,3 %, vómito en un 70,5 % y convulsiones en el 54,5 %. La cefalea solo se evidenció en el 40,9 % de los casos. Los signos de irritación meníngea también fueron visualizados en un gran porcentaje, la rigidez de nuca en el 70,5 %. En 30 pacientes la toma de la punción lumbar fue posterior al inicio del tratamiento antibiótico, es por esto que solo en el 22,5 % de los casos se pudo obtener aislamiento microbiológico en el cultivo de LCR, siendo S .pneumoniae el microorganismo predominante. El segundo microorganismo aislado en frecuencia fue H. influenzae no tipificable y N. meningitidis. En el 50 % de la muestra evaluada se observaron complicaciones neurológicas, entre ellas: algún tipo de déficit motor, epilepsia, hipoacusia neurosensorial, y compromiso de pares craneanos. La mortalidad fue del 13,6 %. CONCLUSIÓN: El Streptococcus pneumoniae es el agente causal más frecuente, aunque no se debe descuidar la vigilancia epidemiológica de H. influenzae no tipificable y Neisseria meningitidis. Este estudio nos muestra las dificultades que involucra la identificación de la etiología de la meningitis. Muchos casos recibieron antibióticos antes del diagnóstico definitivo. Aun utilizando todas las técnicas de laboratorio, un número considerable de pacientes permanecieron sin diagnóstico definitivo. Por lo tanto, conocer el perfil etiológico de las meningitis en una región, antes de ser una simple curiosidad médica, tiene valor fundamental en la toma de decisiones terapéuticas y profilácticas.

SUMMARY OBJECTIVES: To describe the clinical and paraclinical features in children between 3 months and 14 years of age with acute bacterial meningitis diagnosis. To describe neuroimaging finds, to specify germs isolated and its susceptibility pattern by antiobiogram. To establish neurological after hospital discharge-effects and to document the frequency of mortality in hospitalized patients by ABM at San Vicente Foundation University Hospital (from HUSVF). MATERIALS AND METHODS: Retrospective-descriptive study. Registries of patients with acute bacterial meningitis diagnose at the moment of hospital discharge were included, since January 1, 2011 to December 31, 2015. Data was collected from medical histories at the HUSVF Children Hospital. Patients admitted were children between 3 months and 14 years of age with acute bacterial meningitis clinical diagnose having altered CSF; they also had to fulfill one ore more of the following requirements: positive hemoculture, positive latex, culture isolation of CSF, or clinical requirement and suggestive ABM evolution. Demographic information, clinical manifestations while hospital admission and findings in laboratory tests were extracted as well as after-effect presence and complications during the hospital-stay. SPSS IBM Statistics 23,0 was used. RESULTS: 44 patients with an average of 63,7 months (SD 56,4) were included. Male sex was predominant with 27 boys (61,4%). Most of the patients (86,4%) lived in Antioquia, Colombia. Most frequent symptoms were: fever 77,3%, altered state of consciousness 77,3%, vomiting 70,5%, and seizure 54,5%. Only 40,9% of the cases showed headache. Meningeal irritation had also a high percentage, neck stiffness had 70,5%. Lumbar puncture was performed after antibiotic treatment in 30 patients, so that microbiological isolation in CSF culture was only possible in 22,5% of the cases, being the S. pneumoniae the predominant microorganism. The second isolated microorganism by frecuency was non typeable H. influenzae and N. meningitidis. Neurological deficits were observed in the 50% of the sample like: sort of motor deficit, epilepsy, sensorineural hearing loss, and alteration of cranial nerves. Mortality represented 13,6%. CONCLUSIONS: Streptococcus pneumoniae is the most frequent agent-cause though H. influenzae tipificable and Neisseria meningitides epidemiological monitoring must not be overlooked. This study shows difficulties involving meningitis etiology identification. Many of the cases get antibiotics before definitive diagnose. Although all laboratory techniques were used, representative number of patients remained without diagnoses. Therefore, to know meningitis etiological profile at a region is not only a simple medical curiosity, it is a fundamental basis for making therapeutic and prophylactic decisions.

RESUMO

ABSTRACT The use of anticoagulants and antiplatelet agents has largely increased. Diagnostic lumbar puncture in patients taking these drugs represents a challenge considering the opposing risks of bleeding and thrombotic complications. To date there are no controlled trials, specific guidelines, nor clear recommendations in this area. In the present review we make some recommendations about lumbar puncture in patients using these drugs. Our recommendations take into consideration the pharmacology of these drugs, the thrombotic risk according to the underlying disease, and the urgency in cerebrospinal fluid analysis. Evaluating such information and a rigorous monitoring of neurological symptoms after lumbar puncture are crucial to minimize the risk of hemorrhage associated neurological deficits. An individualized patient decision-making and an effective communication between the assistant physician and the responsible for conducting the lumbar puncture are essential to minimize potential risks.

RESUMO O uso de anticoagulantes e de agentes antiplaquetários tem aumentado nos últimos anos. A realização de punção lombar diagnóstica em pacientes utilizando tais medicamentos representa um desafio, em função dos riscos de complicações hemorrágicas ou trombóticas, estas últimas em pacientes que interrompem o tratamento para a realização do procedimento. Não há ainda estudos controlados nem diretrizes específicas nesta área. Neste artigo de revisão, algumas recomendações são feitas, levando-se em conta aspectos farmacológicos destas medicações, o risco de complicações trombóticas de acordo com a doença de base, e a urgência na coleta do líquor. A avaliação cuidadosa destas informações e uma monitorização neurológica rigorosa visando a detecção e o tratamento precoce de complicações podem reduzir o risco de sequelas neurológicas decorrentes de hemorragia. Uma decisão individualizada e uma efetiva comunicação entre o médico assistente e o responsável pela realização da punção lombar é essencial para minimizar potenciais riscos.

RESUMO

RESUMEN El objetivo del estudio fue analizar el uso de la punción lumbar (PL) en las sospechas de sepsis neonatal tardía. Se utilizó una cohorte de 414 neonatos con peso al nacer <2000 g en tres hospitales de Lima. Se realizó la PL en 45/214 (21,0%) sospechas de sepsis y en 13/48 (27,1%) sepsis confirmadas por hemocultivo. Se diagnosticó meningitis en 8/214 (3,7%) sospechas y en 8/45 (17,5%) episodios en los que se realizó la PL. El tiempo de tratamiento de los episodios sin PL fue similar a los episodios de sepsis con meningitis descartada y menor a los episodios de meningitis. El uso de la PL es bajo, lo que puede resultar en meningitis no diagnosticadas y tratadas inadecuadamente. Es necesario reforzar la importancia de la PL en la evaluación de sepsis neonatal.

ABSTRACT The objective of this study was to analyze the use of lumbar punctures (LP) in the evaluation of late-onset neonatal sepsis. It is recommended to perform an LP as part of the evaluation of late-onset sepsis. We used a cohort of 414 newborns with a birth weight <2000g in three hospitals in Lima. A LP was performed in 45/214 (21.0%) of sepsis evaluations and in 13/48 (27.1%) of culture-proven sepsis. Meningitis was diagnosed in 8/214 (3.7%) of the episodes and 8/45 (17.5%) of the evaluations that included an LP. The duration of treatment of the sepsis episodes without a LP and the episodes with a negative LP was similar, and shorter than the episodes with a positive LP. The use of LP in the evaluation of late-onset sepsis is low and can result in undiagnosed and undertreated meningitis. The use of LP in the evaluation of neonatal sepsis must be encouraged in the neonatal units.

RESUMO

La meningitis es una enfermedad cuya importancia es de Salud Pública, no solo por su incidencia, sino también por su mortalidad y secuelas en quienes la padecen. El Sistema Nervioso Central está protegido de manera especial, sin embargo los microorganismos se las ingenian para evadir las defensas; al ser infectadas las meninges, se inicia la respuesta del sistema inmune, piedra angular en la fisiopatología. La manifestación clínica puede ser muy florida, sin embargo es importante reconocer los signos claves para la sospecha oportuna y la realización de exámenes complementarios esenciales en el diagnóstico, tal como la punción lumbar; no se debe olvidar reconocer aquel paciente que previo a este procedimiento, debe de realizarse un estudio de imágenes; a pesar de esto, el inicio de los antibióticos y el uso de glucocorticoide no puede ser retrasado, y se debe administrar en el menor tiempo posible, fundamental para un mejor pronóstico del paciente.

Meningitis is a disease which is of Public Health importance, not only for its incidence, but also its mortality and sequelae in patients. The Central Nervous System is protected in a special way; however microorganisms manage to evade the defenses. When the Meninges are infected, the Immune System's response begins, of great significance in the pathophysiology. The clinical manifestations may be many, but it is important to recognize the key signs for suspicion and timely implementation of essential complementary tests in the diagnosis, such as lumbar puncture.It is vital to recognize the patient prior to the procedure, needs an imaging study. Despite this, the beginning of antibiotics and the use of glucocorticoid must not be delayed and should be administered as soon as possible, essential to a better prognosis.

RESUMO

Introduction: Iatrogenic retroperitoneal haematoma is an infrequent but serious complication of certain surgical procedures. Case presentation: We present the case of a female who developed retroperitoneal haemorrhage after an intradural lumbar puncture, resulting in multiple-organ failure. The diagnosis and treatment of this complication was more difficult than usual because of the presence of bilateral subclavian artery stenosis. Conclusion: Early diagnosis and prompt treatment with either conservative or interventional management is essential in order to decrease associated morbidity. Bilateral non-invasive arterial pressure measurements should be routinely performed in all cases, especially in patients with peripheral artery disease.

Introducción: El hematoma retroperitoneal iatrogénico es una complicación infrecuente pero, en ocasiones, de consecuencias fatales. Presentación del caso: En este artículo describimos el caso de una mujer que sufrió una hemorragia retroperitoneal secundaria a una punción lumbar intradural con evolución hacia el fallo multiorgánico, agravado en su manejo por la presencia de estenosis bilateral de arterias subclavias que dificultó el diagnóstico y el tratamiento. Conclusión: Un diagnóstico precoz y certero del hematoma retroperitoneal, unido a las medidas de soporte necesarias y a un abordaje quirúrgico eficiente cuando se requiera, se antojan fundamentales para evitar un desenlace mortal. Por otro lado, la medición de la presión arterial de forma bilateral debe ser una medida rutinaria en todos los pacientes, pero más aún en aquellos casos con enfermedad arterial periférica.

RESUMO

A sífilis é um agravo infectocontagioso causado pelo Treponema pallidum, de transmissão predominantemente sexual, que afeta 12 milhões de pessoas por ano no mundo. Se não curada em suas fases iniciais, predispõe a complicações potencialmente graves. Uma dessas complicações é a neurossífilis, caracterizada pela invasão do sistema nervoso central pelo T. Pallidum em qualquer fase da história natural da infecção, cuja mortalidade ultrapassa 60%. Em pessoas com HIV, essa complicação pode ser mais frequente, surgir após um menor período de latência e ser mais agressiva. Na maioria das vezes, a neurossífilis é assintomática ou se apresenta por meio de manifestações clínicas pouco específicas que demandam alto índice de suspeição e propedêutica laboratorial invasiva. O diagnóstico é feito através de provas sorológicas ou de biologia molecular no líquor. A controvérsia é sobre a indicação desse diagnóstico e respectivo tratamento nos casos assintomáticos, principalmente em se tratando de pessoas que vivem com o HIV. Esta revisão narrativa da literatura concluiu que a punção lombar propedêutica da neurossífilis está indicada em pessoas que apresentam sororreagência ao VDRL, associado a uma ou mais das seguintes condições: manifestações neurológicas na esfera motora, sensitiva ou cognitiva; sintomatologia sifilítica ou VDRL maior que 1:8 pós-tratamento, descartada reinfecção; pessoas com HIV na presença de CD4 menor que 351 células/mm3 e VDRL maior ou igual a 1:32; e evidência de doença sifilítica terciária não neurológica em atividade (goma ou aortite). Feito o diagnóstico a partir desses critérios, o tratamento específico deverá ser administrado mesmo nos casos assintomáticos.

Syphilis is an infect-contagious injury caused by Treponema pallidum, of predominantly sexual transmission, which affects 12 million people worldwide each year. If not cured in its early stages, predisposes to potentially serious complications. One of the complications is neurosyphilis, characterized by the invasion of the central nervous system by T. pallidum in any phase of the natural history of the disease, whose mortality exceeds 60%. In people with HIV, this complication may be more frequent, arising after a shorter period of latency and also be more aggressive. Most often, neurosyphilis is asymptomatic or presents itself by means of little specific clinical manifestations, which require high index of suspicion and invasive laboratory propaedeutics. The diagnosis is made by serological tests or molecular biology study on the cerebrospinal fluid. The controversy is about the indication of this diagnosis and respective treatment in asymptomatic cases, mainly in people living with HIV. This narrative review of the literature concluded that propaedeutic lumbar puncture of neurosyphilis is recommended for people who have serum-reactivity to the VDRL, associated with one or more of the following conditions: neurological manifestations on motor, sensory or cognitive sphere; syphilitic symptoms or VDRL greater than 1:8 post-treatment, discarded reinfection; persons with HIV at the presence of CD4 less than 351 cells/mm3 and VDRL greater than or equal to 1:32; and evidence of no neurological tertiary syphilitic disease inactivity (gumma or aortitis). Made the diagnose from these criteria, specific treatment should be given even in asymptomatic cases.

RESUMO

INTRODUCTION: Lumbar punctures (LP) in patients presenting thrombocytopenia are linked to the possibility of bleeding and spinal hematomas. The minimum platelet count required for the safe performance of spinal procedures is still under discussion. Children with some oncology diseases require routinely lumbar punctures; such patients often present thrombocytopenia, making this group an ideal population to study the association between lumbar puncture in thrombocytopenic patients and complications. OBJECTIVES: To determine the platelet count of oncology children undergone lumbar punctures and the occurrence of spinal hematomas. METHOD: Observational longitudinal study. It included a retrospective analysis of electronic medical records of oncology patients submitted to LP for intrathecal chemotherapy between January 2004 and October 2011, carried out at the 'Instituto de Medicina Integral Prof. Fernando Figueira (IMIP)', Recife, Brazil. RESULTS: We evaluated 9088 lumbar punctures performed in 440 patients. The platelet count distribution before lumbar punctures was as follows: 25 punctures had zero to 10,000 platelets per mm(3), 67 punctures had between 10,000 and 20,000 platelets per mm(3), 88 had between 20,000 and 30,000 platelets per mm(3), 92 punctures had between 30,000 and 40,000 platelets per mm(3), 107 punctures had between 40,000 and 50,000 platelets per mm(3), and 729 punctures had between 50,000 and 100,000 platelets per mm(3). In this series, the incidence of bloody tap was 16.9% (1112 lumbar punctures of 6552 had more than ten erythrocytes). No complications were observed. CONCLUSIONS: Even in thrombocytopenic patient, an epidural hematoma would be a relatively rare complication following lumbar puncture. Despite the large number of punctures performed on patients with platelet counts below 100,000 mm(-3) (n = 1108), further studies are necessary in order to determine a lower safe platelet count threshold for the performance of lumbar punctures in healthy patients undergoing neuraxial anesthesia.

RESUMO

A punção liquórica cervical lateral no espaço C1-C2 foi descrita a partir de uma modificação da técnica utilizada para cordotomia percutânea anterolateral. Neste artigo, é descrita uma série de 14 pacientes vítimas de trauma, submetidos à punção liquórica cervical lateral. Todos os procedimentos foram realizados para pesquisa de meningite bacteriana. Presença de escara lombar e occipital, fratura instável de coluna vertebral, tração ou imobilização ortopédica e ventilação mecânica controlada foram os principais motivos para se optar pela punção liquórica cervical lateral. A taxa de sucesso foi de 93%. Não foram evidenciadas maiores complicações per ou pósprocedimento. A punção liquórica cervical lateral se mostrou um método eficaz para obtenção de líquor em pacientes vítimas de trauma, pois não requer mudança de decúbito ou angulação da cabeceira, o que evita complicações em pacientes entubados e com fratura instável de coluna vertebral. Estudos prévios sugerem que a punção liquórica cervical lateral deve ser o método de escolha em pacientes vítimas de trauma com restrição de mobilização.

The lateral cervical spinal puncture at C1-C2 was described from a modification of the technique used for percutaneous anterolateral cordotomy. In this article, we describe a series of 14 patients of multiple trauma victims who underwent lateral cervical spinalpuncture. All procedures were performed as a screening for bacterial meningitis. Low back and occipital ulcer, unstable spinal fractures, orthopedic traction or immobilization and ventilated patients were the main reasons to opt for the lateral cervical spinal puncture over standard techniques of liquor puncture. The success rate was 93%. There was not major complication per or post procedural. The lateral cervical spinal puncture proved to be an effective method of obtaining liquor in victims of trauma because it does not requires changing position or rotation of the head, preventing complications in patients with orotraqueal tube and unstable spinal fractures. Previous studies suggest that the lateral cervical spinal puncture should be the method of choice in trauma patients with restriction of mobilization.

RESUMO

Resumen:

Introducción: los síntomas subjetivos de la cefalea postpunción lumbar se relacionan con los elementos neurales estimulados. Objetivo: caracterizar el comportamiento de la cefalea postpunción dural en pacientes tratados con bloqueo espinal en los hospitales Lucía Íñiguez y Vladimir I Lenin. Método: estudio descriptivo transversal en 80 pacientes de 16 a 60 años, tratados en cirugía con anestesia espinal en el servicio de anestesiología de los hospitales Lucía Iñiguez y Vladimir I Lenin, entre noviembre de 2012 y abril de 2013, según estado físico: pacientes sanos y pacientes con enfermedades sistémicas compensadas. Se aplicó el método de Chi cuadrado. Resultados: entre las edades de 16-30 años predomina el grupo ASA I en la aparición de cefalea postpunción dural con el 15%, la cefalea postpunción dural apareció en el 10,0% de los pacientes donde se utilizó aguja número 22G, el 16,3% presentó cefalea postpunción dural al movilizarse fuera de cama y apareciendo la cefalea en las primeras 24 h en el 8,8% de los pacientes estudiados y en el 7,5% apareció después de las 24 h. Conclusiones: predominó el grupo de 16 a 30 años y género femenino. Según el estado físico se presentó la cefalea con mayor frecuencia en pacientes sanos. La movilización temprana del paciente contribuye a disminuir la frecuencia de aparición de la cefalea.
