Asociación entre meningitis y punción dural en ratas bacterémicas. Un análisis crítico / The Association between meningitis and dural puncture in bacteremic rats. A critical análisis

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.

Cervical brucellar spondylitis causing incomplete limb paralysis

Abstract Brucellosis, a zoonosis with worldwide distribution, is a systemic infection caused by bacteria of the genus Brucella. Meanwhile, brucellosis often causes complications, such as osteoarticular involvement, and spondylitis is the most prevalent and important clinical form. Here, is a case of cervical brucellar spondylitis causing incomplete limb paralysis in a middle-aged male. The diagnosis was based on clinical history, and supported by Brucella serology and magnetic resonance imaging. Quadruple antibacterial treatment continued for four weeks. In this case, the epidural abscess causing spinal cord compression resolved without surgery. In addition, the patient had recovered from most of the neurologic deficits.

High cervical spine spondylodiscitis management and literature review / Espondilodiscite da coluna cervical alta: manejo e revisão da literatura

Summary Spondylodiscitis affecting the cervical spine is the most unusual type. Disease progression can be dramatic, even causing quadriplegia and death. We present an unusual case that progressed with osteolytic lesions between C2 and C3, causing cord compression and epidural abscess. The patient was treated surgically by a double approach and improved without neurological deficits and with better inflammatory markers. We reviewed the current literature on the subject.

Resumo A espondilodiscite, que acomete a coluna cervical, é a de localização mais rara. Pode ter uma evolução dramática, inclusive causando tetraplegia e óbito. Apresentamos um caso atípico que evoluiu com lesões osteolíticas entre C2 e C3, causando compressão medular e abscesso epidural. O paciente foi submetido a tratamento cirúrgico por dupla abordagem e evoluiu bem, sem déficits neurológicos e com melhora dos marcadores inflamatórios. Revisamos a literatura vigente sobre o assunto.

Abscesso subperiosteal com extensão epidural devido à rinossinusite aguda em criança de dez anos / Subperiosteal abscess with epidural extension due to acute rhinosinusitis in a ten-year-old child

RESUMO A rinossinusite aguda é uma das afecções mais prevalentes das vias aéreas superiores. Fatores anatômicos presentes em crianças e jovens propiciam o aparecimento de complicações orbitárias. Embora mais raras, as complicações intracranianas das rinossinusites perfazem um grau alto de letalidade, são mais comuns em pacientes acima de sete anos, e devem ser tratadas por uma equipe multidisciplinar.

ABSTRACT Acute rhinosinusitis is one of the most prevalent diseases of the upper airways. Anatomical factors present in children and young people allow for the onset of orbital complications. Although rare, intracranial complications of sinusitis account for a high degree of lethality, are more common in patients over the age of seven, and should be treated by a multidisciplinary team.

A Case of Epidural Abscess Occurred after Liver Abscess Complicated by Transarterial Chemoembolization in a Patient with Metastatic Cancer to Liver / 대한소화기학회지

Transarterial chemoembolization (TACE) is one of the most effective therapies for unresectable hepatocelluar carcinoma or metastatic hypervascular tumors. Abscess occurring in the other organs beside the liver after TACE is a complication that often occurs, sometimes potentially fatal. We report a case of spinal epidural abscess occurred after liver abscess complicated by TACE in a patient with metastatic neuroendocrine tumors to the liver. A 67-year-old female underwent TACE first for the metastatic lesions to liver, with a history of pancreatoduodenectomy for the primary pancreatic neuroendocrine tumor. Four days after TACE, sudden high fever occurred, and liver abscess was found on abdominal CT. Two days later, back pain and radiating pain to the right leg occurred, and lumbar spine MRI showed spinal epidural abscess. After intravenous antibiotics for 8 weeks and partial laminectomy, the patient recovered and was discharged without complications.

Diabetes mellitus and spinal epidural abscess: clinical or surgical treatment? / Diabetes melito e abscesso epidural espinhal: tratamento clínico ou cirúrgico?

Spinal epidural abscess (SEA) is an uncommon condition and its most important predisposing factor is diabetes mellitus. Although the treatment of choice is prompt surgical abscess evacuation, followed by antibiotic therapy, successful conservative treatment of SEA has been reported in some cases. We describe a SEA case in a 23-year old white woman with diabetes for 14 years, who was successfully treated only with antibiotics, and achieved full recovery at the fourth month of follow-up.

O abscesso epidural espinhal (AEE) é uma doença incomum e o diabetes melito é o seu fator predisponente mais importante. O tratamento de escolha é a imediata drenagem cirúrgica, seguida de antibioticoterapia, entretanto, casos já foram relatados em que o AEE foi tratado clinicamente com sucesso. Descrevemos um caso de AEE em um paciente diabético tratado satisfatoriamente com uso isolado de antibióticos e que evoluiu com recuperação total no quarto mês de seguimento.

Unusual manifestations of brucellosis: a retrospective case series in a tertiary care Greek University Hospital

Brucellosis remains a diagnostic puzzle. We retrospectively studied the case notes of 105 patients with brucellosis who were admitted in the Department of Internal Medicine of the University of Patras Hospital, a tertiary care institution serving an extended rural area in western Greece, from 2003 to 2006. Five unusual causes of brucellosis were identified: hepatic, epidural and thyroid abscesses, intrahepatic cholestatic liver disease and pancytopenia. Virtually every human organ and system can be involved in brucellosis, which highlights the need to include brucellosis in the differential diagnosis, especially in endemic areas

Espondilodiscitis con absceso epidural espinal y del psoas por Mycobacterium tuberculosis / Spondylodiscitis with spinal epidural abscess and psoas muscle abscess due to Mycobacterium tuberculosis

El absceso epidural espinal es un proceso infeccioso caracterizado por la acumulación de material purulento y tejido de granulación en el espacio epidural. Se trata de una complicación poco frecuente, cuyo diagnóstico habitualmente se demora, lo cual se asocia con elevada morbimortalidad. Cuando el agente etiológico es Mycobacterium tuberculosis, la fiebre prolongada y el dolor dorsolumbar son los síntomas más comunes. La resonancia magnética es el método de elección para el diagnóstico de la localización y extensión del proceso. El diagnóstico precoz seguido del tratamiento específico (descompresión neuroquirúrgica y tuberculostáticos) son necesarios para mejorar el pronóstico de estos pacientes y evitar secuelas neurológicas definitivas.

Brucellar spinal epidural abscess - a very rare entity

Complicações intracranianas das otites médias crônicas supurativas em crianças / Intracranial complications of chronic suppurative otitis media in children

Apesar de sua significativa diminuição após o advento dos antibióticos, as complicações intracranianas das otites médias ainda representam uma situação de risco, uma vez que a taxa de mortalidade permanece alta, chegando a 36 por cento. Entre as formas mais comuns estão meningite, abscesso cerebral, abscesso extradural e tromboflebite do seio lateral. Um alto índice de suspeição é fundamental para seu diagnóstico e manejo precoces. É importante a identificação de casos atípicos que podem estar mascarados pelo uso de antimicrobianos. OBJETIVO: Apresentamos seis casos de complicações intracranianas por otite média em crianças e adolescentes ocorridos no período de dois anos no Serviço de Otorrinolaringologia do Complexo Hospitalar Santa Casa (CHSC). FORMA DE ESTUDO: relato de série.

Cervical Epidural Abscess Secondary to Aorto-Duodenal Fistula: A Case Report

Although cervical epidural abscess is rare, it should be strongly suspected in any patient with unexplainable neck pain and fever, especially when the patient has a predisposing factor for this infectious process. The authors report a case of cervical epidural abscess in a 39-yr-old man with an aorto-duodenal fistula, which complicated the interposition of artificial graft for abdominal aortic aneurysm rupture, which had undertaken 40 months before. Timely detection and intervention rendered him a full neurological recovery. This extremely rare case is presented with a literature review.
