ABSTRACT

Meningitis is a significant viral, bacterial, or fungal infection of the meninges that cover and protect the brain and the spinal cord. Symptoms of meningitis may present rapidly or develop gradually over a period of days, manifesting with common prodromal flu-like symptoms of headache, photophobia, fever, nuchal rigidity, myalgias, and fatigue. Character and significance of symptoms vary by patient age. Symptoms of infection may improve spontaneously or worsen, becoming potentially lethal. Early recognition and treatment of meningitis are crucial to prevent morbidity and mortality. The case reviewed in this article focuses on viral meningitis in a pediatric patient that may be unrecognized or underreported because of indistinct symptoms. Epidemiology, pathophysiology, presentation, assessment techniques, diagnostics, clinical management, and health promotion relevant to viral meningitis are presented.

ABSTRACT

OBJECTIVE: Cerebrospinal fluid (CSF) leukocytes analysis is commonly used to diagnose meningitis and to differentiate bacterial from viral meningitis. Interpreting CSF monocytes can be difficult for physicians, especially in France where lymphocytes and monocytes results are sometimes pooled. PATIENTS AND METHODS: We assessed SF monocytes in patients presenting with microbiologically confirmed meningitis (CSF leukocyte count>10/mm3 for adults or >30/mm3 for children<2 months), i.e. bacterial meningitis (BM), viral meningitis (VM), and neuroborreliosis (NB). RESULTS: Two-hundred patients (82 BM, 86 VM, and 32 NB) were included. The proportions of monocytes were higher in VM (median 8%; range 0-57%) than in BM (median 5%; range 0-60%, P=0.03) or NB (median 5%; range 0-53%, P=0.46), with a high value overlap between conditions. CONCLUSION: CSF monocytes should not be used to discriminate BM from VM and NB because of value overlaps.

ABSTRACT

Objective: To determine etiology and risk factors of meningitis in patients admitted a tertiary referral Hospital in Harare. Design: Cross-Sectional Study. Setting: Urban Referral Health Facility. Subjects: Patients suspected of having Meningitis admitted at Parirenyatwa Hospital were consecutively consented and recruited into the study until sample size accrual. Main Outcome Measures: Prevalence of pathogens associated with Meningitis. Risk factors of meningitis. Results: Two Hundred and Ninety Six (296) clinically suspected meningitis patients were recruited into the study, 51.7 %( n=115) were male. Meningitis was confirmed in 20.6% (n=61) cases with the following pathogen proportions, C. neoformans - 45.9 %( n=28), S. pneumoniae ­ 27.9 % (n=17), TBM ­ 4.9 %( n=3), probable viral meningitis ­ 6.6% (n=4 and other bacteria- 14.8% (n=9). Patients from crowded households were also more likely to suffer from meningitis than those from sparsely populated households (p<0.001). Conclusion: The use of Latex agglutination increases the proportion of detected pathogens both fungal and bacterial when used in conjunction with CSF gram stain and culture. Cryptococcus neoformans and S. pneumoniae are the leading causes of meningitis in patients admitted at Parirenyatwa Hospital.

ABSTRACT

Magnetic resonance imaging findings of meningitis are usually nonspecific with respect to the causative pathogen because the brain response to these insults is similar in most cases. In this article, we will use a few representative cases to describe the characteristic magnetic resonance findings of meningitis and its complications, including ventriculitis.

ABSTRACT

An 18-year-old woman presented with a progressively worsening headache, photophobia feverishness and vomiting. Three weeks previously she had returned to the UK from a trip to Peru. At presentation, she had clinical signs of meningism. On admission, blood tests showed a mild lymphopenia, with a normal C reactive protein and white cell count. Chest X-ray and CT of the head were normal. Cerebrospinal fluid (CSF) microscopy was normal. CSF protein and glucose were in the normal range. MRI of the head and cerebral angiography were also normal. Subsequent molecular testing of CSF detected enterovirus RNA by reverse transcriptase PCR. The patient's clinical syndrome correlated with her virological diagnosis and no other cause of her symptoms was found. Her symptoms were self-limiting and improved with supportive management. This case illustrates an important example of viral central nervous system infection presenting clinically as meningitis but with normal CSF microscopy.

ABSTRACT

PURPOSE OF REVIEW: Most cases of acute meningitis are infectious and result from a potentially wide range of bacterial and viral pathogens. The organized approach to the patient with suspected meningitis enables the prompt administration of antibiotics, possibly corticosteroids, and diagnostic testing with neuroimaging and spinal fluid analysis. RECENT FINDINGS: Acute meningitis is infectious in most cases and caused by a potentially wide range of bacterial and viral pathogens. Shifts in the epidemiology of bacterial pathogens have been influenced by changes in vaccines and their implementation. Seasonal and environmental changes influence the likely viral and rickettsial pathogens. SUMMARY: The organized approach to the patient with suspected meningitis enables the prompt administration of antibiotics, possibly corticosteroids, and diagnostic testing with neuroimaging and spinal fluid analysis. Pertinent testing and treatment can vary with the clinical presentation, season, and possible exposures. This article reviews the epidemiology, clinical presentation, diagnosis, and treatment of acute meningitis.

ABSTRACT

INTRODUCTION AND OBJECTIVES: our study aims to identify the clinical and epidemiological characteristics of viral meningitis in our environment and observe the differences with age. MATERIAL AND METHODS: retrospective study of viral meningitis that required admission to our hospital between 2000 and 2008. We compare characteristics between groups of children (under 15 years) and adults (15 years or older). Results. The viral meningitis prevalent in males, is higher during the summer months and the agent most involved is enterovirus. Children are seen in the hospital with shorter time of onset and their average stay is less. In children, the analytical data show greater systemic disorder, whilst in adults the in the cerebrospinal fluid anomalies are more important. CONCLUSIONS: the viral meningitis in our environment is more common in males and in summer months. The clinical presentation and prodrome is similar in children and adults, although the average hospital stay is less in children of this age probably because the clinical outcome is shorter. The analytical data show that children have a higher systemic inflammation but lower CSF level, probably because lumbar puncture is performed earlier than in adults. Enteroviruses are common pathogens in both children and adults.

ABSTRACT

OBJECTIVES: To evaluate the potential role of CSF lactate level in the diagnosis of acute bacterial meningitis and in the differentiation between viral and bacterial meningitis. METHODS: This was a hospital based observational study, conducted at Infectious Diseases Unit, Rashid Hospital Dubai, United Arab Emirates, from July 2004 to June 2007. The patients with clinical diagnosis of acute bacterial meningitis and who had CSF Gram stain/culture positive, CSF analysis suggestive of bacterial meningitis with negative Gram stain and culture but blood culture positive for bacteria and patients with clinical diagnosis suggestive of viral meningitis supported by CSF chemical analysis with negative Gram stain and culture as well as negative blood culture for bacteria were included in the study. CT scan brain was done for all patients before lumber puncture and CSF and blood samples were collected immediately after admission. CSF chemical analysis including lactate level was done on first spinal tap. The CSF lactate level was tested by Enzymatic Colorimetric method. RESULTS: A total 95 adult patients of acute meningitis (53 bacterial and 42 viral) fulfilled the inclusion criteria. Among 53 bacterial meningitis patients, Neisseria meningitides were isolated in 29 (54.7%), Strept. Pneumoniae in 18 (33.96%), Staph. Aureus in 2 (3.77%), Klebsiell Pneumoniae in 2 (3.77%), Strept. Agalactiae in 1 (1.8%) and E. Coli in 1 (1.8%). All the patients with bacterial meningitis had CSF lactate > 3.8 mmol/l except one, whereas none of the patients with viral meningitis had lactate level > 3.8 mmol/l. The mean CSF lactate level in bacterial meningitis cases amounted to 16.51 +/- 6.14 mmol/l, whereas it was significantly lower in viral group 2.36 +/- 0.6 mmol/l, p < .0001. CONCLUSION: CSF lactate level was significantly high in bacterial than viral meningitis and it can provide pertinent, rapid and reliable diagnostic information. Furthermore, CSF lactate level can also differentiate bacterial meningitis from viral one in a quick and better way.

ABSTRACT

Chronic meningitis is an inflammation of the meninges with subacute onset and persisting cerebrospinal fluid (CSF) abnormalities lasting for at least one month. Several non-infectious and infectious etiologies are known to be causative. The wide range of different etiologies renders the approach to patients with this syndrome particularly difficult. There is no standardized diagnostic procedure, thus, taking an in depth history combined with a complete physical examination is mandatory in every patient.This review aims to present the current knowledge on etiology, neurological course of disease, diagnostic and therapeutic management steps of patients presenting with clinical signs and symptoms of chronic meningitis and meningoencephalitis. Still, the etiology of one third of patients remains unclear, reflecting the diagnostic challenge of this syndrome for each physician or neurologist, respectively. However, most patients with idiopathic chronic meningitis have a relatively good outcome.

ABSTRACT

El diagnóstico rápido de las infecciones agudas del sistema nervioso central (meningitis y encefalitis), tanto virales como bacterianas, tiene gran trascendencia en el tratamiento clínico del paciente, lo cual ayuda a plantear de forma temprana tratamientos que pueden resolver situaciones con afectación vital, evitar tratamientos empíricos innecesarios, disminuir la estancia hospitalaria y facilitar las actuaciones pertinentes en el ámbito de la salud pública. Las técnicas moleculares, sobre todo la reacción en cadena de la polimerasa a tiempo real, se han convertido en nuestro medio en el procedimiento diagnóstico más rápido y sensible en el caso de meningitis y encefalitis virales autóctonas, y cada día tienen más protagonismo en el diagnóstico y el control de las meningitis bacterianas agudas más frecuentes. La automatización y la utilización de sistemas cerrados pueden facilitar la generalización del uso de las técnicas moleculares a la mayoría de los laboratorios para el diagnóstico de estos procesos neurológicos(AU)


Rapid diagnosis of acute viral and bacterial infections of the central nervous system (meningitis and encephalitis) is highly important for the clinical management of the patient and helps to establish early therapy that may solve life-threatening situations, to avoid unnecessary empirical treatments, to reduce hospital stay, and to facilitate appropriate interventions in the context of public health. Molecular techniques, especially real-time polymerase chain reaction, have become the fastest and most sensitive diagnostic procedures for autochthonous viral meningitis and encephalitis, and their role is becoming increasingly important for the diagnosis and control of most frequent acute bacterial meningitides. Automatic and closed systems may encourage the widespread and systematic use of molecular techniques for the diagnosis of these neurological syndromes in most laboratories(AU)

ABSTRACT

INTRODUCTION: Our main aims were to establish criteria for early distinction between meningococcal disease and other conditions with similar clinical features, and to identify other causes of haemorrhagic rashes accompanied by fever. MATERIALS AND METHODS: This prospective study comprised 264 infants and children hospitalised with fever and skin haemorrhages. RESULTS: We identified an aetiological agent in 28%: 15% had meningococcal disease, 2% another invasive bacterial infection, 7% enterovirus infection, and 4% adenovirus infection. Five clinical variables discriminated meningococcal disease from other conditions on admission: skin haemorrhages of (1) characteristic appearance; (2) universal distribution and (3) a maximum diameter of > 2 mm; (4) poor general condition; and (5) nuchal rigidity. DISCUSSION: If any two or more of these clinical variables were present, the probability of identifying a patient with meningococcal disease was 97% and the false-positive rate was only 12%. This diagnostic algorithm did not identify children in whom septicaemia was caused by other bacterial species.

ABSTRACT

A polymerase chain reaction kit (AMPLICOR EV) for the detection of enteroviruses (EV-PCR) in the cerebrospinal fluid (CSF) was evaluated in clinical conditions in a prospective blinded-intention study. Forty-three children (mean age 2.7 years) hospitalized for suspected meningitis or fever of unclear etiology were enrolled. EV-PCR was performed on a daily basis. Results were available in less than 2 days in 72% of cases. EV-PCR was positive in nine (21%) children, including three infants without CSF pleocytosis. Knowing their EV-PCR result would have allowed a saving of 18 hospital days and 12 days of antibiotic therapy. The EV-PCR in the CSF can thus be practically useful for children hospitalized for meningitis or fever if available on-site on a daily basis.

ABSTRACT

OBJECTIVE: The use of antibiotics before and after surgery has made infectious complications of neurotologic surgery rare. The neurosurgical literature cites a rate of postoperative meningitis between 1% and 2% for "clean" cases and 1.5% to 2.5% for "clean contaminated" cases, such as cerebrospinal fluid contact with the middle ear or mastoid. Reports of infections after neurotologic procedures are rare in the otologic literature. In this report, two patients with brain abscess occurring in a delayed fashion after surgery are described. STUDY DESIGN: The study design was a retrospective chart review and case report. SETTING: The study was conducted at a tertiary referral center. RESULTS: Patient 1 underwent a suboccipital craniotomy for removal of an acoustic neuroma and had an uneventful postoperative recovery. Three months after surgery, he reported mild unsteadiness. Examination revealed mild ataxia, which led to repeat magnetic resonance imaging (MRI) and a diagnosis of cerebellar abscess. Patient 2 underwent translabyrinthine removal of an acoustic neuroma complicated by postoperative Pseudomonas aeruginosa meningitis, which responded promptly to intravenous antibiotics. Fifteen months after surgery, he visited a neurologist after having a seizure and was treated with anticonvulsants. After a second episode of seizure, imaging studies showed a temporal lobe abscess. CONCLUSIONS: The signs of intracranial abscess may be subtle and can occur weeks or months after surgery, requiring vigilance and a high index of suspicion for diagnosis. A change in postoperative symptoms after acoustic neuroma surgery should signal further investigation using MRI with gadolinium.

ABSTRACT

Pneumocystis carinii is a common opportunistic pathogen in patients infected with the human immunodeficiency virus (HIV). Pneumocystis carinii pneumonia is common, while extrapulmonary infections with Pneumocystis carinii have been reported sparingly. The clinical features are frequently nonspecific. The detection of Pneumocystis carinii in cerebrospinal fluid (CSF) has not been reported thus far. In this report, an unusual case of Pneumocystis carinii meningoradiculitis in an HIV-infected patient who had previously received primary prophylaxis with trimethoprim-sulfamethoxazole is presented.

ABSTRACT

DNA amplification with the polymerase chain reaction (PCR) technique was used as a diagnostic test on cerebrospinal fluid samples in cases where herpesvirus infection of the central nervous system (CNS) was suspected. During the period, 1992-93, 47 (8.9%) of 528 patients tested were positive for one or another of the following herpesviruses: herpes simplex virus type 1 (n = 16) or type 2 (n = 9), cytomegalovirus (n = 16), varicella-zoster virus (n = 4), or Epstein-Barr virus (n = 2). The study showed PCR to be a rapid and useful diagnostic method in clinical routine, enabling early antiviral intervention in several cases with an atypical clinical picture. Moreover, cytomegalovirus was found to be an important CNS pathogen in addition to herpes simplex virus, especially during childhood.

ABSTRACT

Viral meningitis are the most frequent cause of clear cerebrospinal fluid (CSF) meningitis and are usually benign. The viral nature is suggested by clinical arguments (context, associated manifestations) and particularly the analysis of CSF, typically lymphocytic. However, problems of CSF interpretation may occur during the polymorphonuclear reaction at the beginning of such meningitis and after elevated protein or low glucose concentration. The main differential diagnosis are: partially treated bacterial meningitis, the beginning of meningococcal meningitis, listeriosis or tuberculous meningitis which need and urgent and specific treatment. The most common agents are the enteroviruses. The etiology can only be detected through careful virological investigations. These studies may be useful in outbreaks or in epidemiological studies.
