Vertebral artery dissection associated with viral meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Vertebral artery dissection (VAD is often associated with trauma or occurs spontaneously, inevitably causing some neurological deficits. Even though acute infection can be related to the development of spontaneous VAD (sVAD, VAD associated with viral meningitis has never been reported in the literature. Case presentation A 42-year-old man with fever, sore throat, and runny nose developed sudden onset of occipital headache, vertigo, transient confusion, diplopia, and ataxia. Brain stem encephalitis was diagnosed initially because the cerebrospinal fluid (CSF study showed inflammatory changes. However, subsequent diffusion-weighted (DWI magnetic resonance imaging of his brain demonstrated left lateral medullary infarction, and the digital subtraction angiography (DSA confirmed VAD involving left V4 segment of the artery. Consequently, the patient was diagnosed as VAD accompanied by viral meningitis. Conclusion This case suggests that viral meningitis might lead to inflammatory injury of the vertebral arterial wall, even sVAD with multiple neurological symptoms.

[Embolization of the feeding artery of a meningioma with dangerous vascular anastomosis between the middle meningeal artery and the ophthalmic artery].  

Science.gov (United States)

Preoperative embolization of intracranial meningioma has been applied to reduce intraoperative blood loss and to facilitate microsurgical removal of a tumor. It is well known that one of the reasons of the neurological risk of embolization is due to dangerous anastomosis between the extracranial and the intracranial arteries. One of the most known and dangerous case of anastomosis is between the middle meningeal artery to the ophthalmic artery. A 48-year-old woman underwent preoperative embolization of a large right middle cranial fossa meningioma. The right external carotid angiogram showed that the tumor was fed by the right middle meningeal artery and there was no branch to the right orbital region. The right internal carotid angiogram showed that the right ophthalmic artery originated from the right internal carotid artery and there was no branch to the tumor. The selective angiogram of the anterior branch of the middle meningeal artery disclosed the anastomosis to the right ophthalmic artery. Following embolization of the anterior branch of the middle meningeal artery, the patient underwent embolization of the main feeding branch of the meningioma. She successfully underwent surgical removal of the tumor without any blood transfusion and was discharged without neurological deficit. In addition, to avoid complication in embolization of the feeding artery of a skull base meningioma, clinicians must be aware of the dangerous anastomosis between the middle meningeal artery and the ophthalmic artery, even if conventional external and internal carotid angiograms do not show any anastomosis.

Intraventricular haemorrhage due to ruptured posterior inferior cerebellar artery aneurysm in tuberculous meningitis.  

Science.gov (United States)

A 9-year-old Asian boy with known miliary tuberculosis, tuberculous meningitis and hydrocephalus was successfully treated with chemotherapy and ventriculoperitoneal shunting, but re-presented 7 months later with an intraventricular haemorrhage secondary to a ruptured left posterior inferior cerebellar artery mycotic aneurysm. The aneurysm was successfully treated by craniotomy and clipping. Tuberculous mycotic intracranial aneurysms are rare, but they should be considered in patients with tuberculous meningitis, particularly when there is a rapid neurological deterioration which may represent rupture.

Accessory Meningeal Arterial Supply to the Posterior Nasal Cavity: Another Reason for Failed Endovascular Treatment of Epistaxis  

International Nuclear Information System (INIS)

A patient with intractable posterior epistaxis was treated with embolization of the ipsilateral sphenopalatine and facial arteries and contralateral sphenopalatine artery. She continued to bleed despite a seemingly adequate embolization procedure. A second angiogram revealed a significant collateral blood supply to the posterior nasal cavity from the accessory meningeal artery not identified during the first procedure. This was then embolized with no further epistaxis encountered. This case demonstrates yet another collateral arterial pathway that might account for a failed embolization

The measure for problematic case with middle meningeal artery origin ophthalmic artery in front-temporal craniotomy and a part of DSA. Preservation of visual function  

International Nuclear Information System (INIS)

Because of the recent development of high-performance 3-dimensional computed tomography (3D-CTA), magnetic resonance angiography (MRA) and the consideration of the risk of digital subtraction angiography (DSA), DSA is not always necessary in performing surgery for cerebral aneurysms. However, DSA was necessary in patients in whom the ophthalmic artery from the internal carotid artery (IC) was not visualized on 3D-CTA or MRA, in order to predict the risk of blindness after front-temporal craniotomy. In this study, we investigated the preoperative evaluation and the surgical procedure for 330 cases of front-temporal craniotomy for surgery of aneurysm over the past 4.5 years. There were 5 cases without ophthalmic artery from IC in DSA or 3D-CTA, 4 cases with an anomalous ophthalmic artery arising from the middle meningeal artery and 1 case with an anomalous ophthalmic artery arising from unknown origin. Microsurgical procedure is needed to preserve the middle meningeal artery in front-temporal craniotomy in these cases with an anomalous ophthalmic artery arising from the middle meningeal artery, because this anomaly places the ophthalmic artery at risk during procedures in which the dura is elevated from the greater and lesser wings of the sphenoid or when the sphenoid ridge is removed in front-temporal craniotomy. Front-temporal craniotomy is difficult in cases with an anomalous ophthalmic artery arising from an unknown origin. (author)(author)

Computed Tomography Angiography for Detection of Middle Meningeal Artery Lesions Associated with Acute Epidural Hematomas  

Science.gov (United States)

Background. The natural history of traumatic aneurysms of the middle meningeal artery (MMA) is not well known, but patients with these lesions are more likely to have delayed bleeds. In this paper, we described a series of patients with epidural hematoma who underwent angiotomography (CTA) for MMA vascular lesion diagnosis. Methods. Eleven patients admitted to our emergency unit with small acute epidural hematoma were prospectively studied. All patients with temporal acute epidural hematomas underwent CTA and cerebral angiogram at our institution for diagnosis of posttraumatic lesions of middle meningeal artery. The findings of angiotomography and digital angiography were reviewed by radiologist and angiographers, respectively, to ensure that the lesions were readily diagnosed without knowing the results of angiotomography and to compare CTA findings with standard angiogram. Results. The causes of head injury were traffic accidents, falls, and aggression. Three of these patients presented traumatic MMA pseudoaneurysm. CT angiography was able to diagnose all of them, with dimensions ranging from 1.5 to 2.8?mm. Conventional angiography confirmed the findings of CT angiography, and the lesions presented with similar dimensions at both methods. Conclusions. We believe that angiotomography can be a useful technique for diagnosis of vascular lesion associated with small epidural hematoma. PMID:24800222

Dilation by CGRP of middle meningeal artery and reversal by sumatriptan in normal volunteers  

DEFF Research Database (Denmark)

BACKGROUND: Calcitonin gene-related peptide (CGRP) plays a fundamental role in the pathophysiology of neurovascular headaches. CGRP infusion causes headache and dilation of cranial vessels. However, it is unknown to what extent CGRP-induced vasodilation contributes to immediate head pain and whether the migraine-specific abortive drug sumatriptan, a 5-hydroxytryptamine 1B/1D agonist, inhibits CGRP-induced immediate vasodilation and headache. METHODS: We performed a double-blind, randomized, placebo-controlled, crossover study in 18 healthy volunteers. We recorded circumference changes of the middle meningeal artery (MMA) and middle cerebral artery (MCA) using magnetic resonance angiography before and after infusion (20 minutes) of 1.5 µg/min human aCGRP or placebo (isotonic saline) as well as after a 6-mg sumatriptan subcutaneous injection. RESULTS: Compared with placebo, CGRP caused significant dilation of MMA (p = 0.006) and no dilation of MCA (p = 0.69). Sumatriptan caused a marked contraction of MMA (15%-25.2%) and marginal contraction of MCA (3.9% to 5.3%). Explorative analysis revealed that sumatriptan had a more selective action on MMA compared with MCA on the CGRP day (p <0.0001) and on the placebo day (p = 0.007). CONCLUSION: These data suggest that exogenous CGRP dilates extracranial vessels and not intracranial, and that sumatriptan exerts part of its antinociceptive action by constricting MMA and not MCA. CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that IV GCRP causes dilation of the MMA but not the MCA in healthy volunteers, and that sumatriptan reverses the dilation of the MMA caused by CGRP.

Central projections of the sensory innervation of the rat middle meningeal artery  

DEFF Research Database (Denmark)

Headaches, especially migraine, involve not only pain but also aspects such as vasodilation of cranial vessels and sensitization of nerve endings, processes dependent on and connected to the central nervous system. To understand pathogenic mechanisms of headache, it is important to elucidate the central projections of sensory nerves that innervate cranial vessels, of which the middle meningeal artery (MMA) is the largest artery supplying the dura mater. In this study, cholera toxin subunit b (CTb) or wheat germ agglutinin-horseradish peroxidase conjugate (WGA-HRP) was applied on the adventitia of MMA. After perfusion fixation, the brainstem, the C1-C4 spinal segments and the trigeminal and C2 dorsal root ganglia were removed and sections from these tissues were processed to visualize transported tracers. Labeled cell bodies were seen ipsilaterally in the trigeminal and C2 dorsal root ganglia. Labeled nerve terminations were found ipsilaterally in the lateral part of the spinal dorsal horn of segments C1-C3 and in the caudal and interpolar parts of the spinal trigeminal nucleus. WGA-HRP labeled terminations were mainly located in laminae I and II, whereas CTb labeled terminations located in laminae III-V. These results indicate that sensory information from the MMA is transmitted through both trigeminal and cervical spinal nerve branches to a region in the central nervous system extending rostrally from the C3 dorsal horn to the interpolar part of the spinal trigeminal nucleus. Our data further substantiates that the sensory innervation of the MMA, in addition to putative nociceptive afferents, include a population of large caliber afferents with an as yet unclear but presumably non-nociceptive role Udgivelsesdato: 2008/5/7

Viral meningitis.  

Science.gov (United States)

Viral meningitis is part of the aseptic meningitis syndrome but must be distinguished from bacterial meningitis on the basis of a careful examination of the CSF and sound clinical judgment. Enteroviruses probably account for the bulk of cases of aseptic meningitis that occur in the United States and which are reported to the Centers for Disease Control each year. The seasonal pattern in the incidence of aseptic meningitis is largely due to the seasonal variation of enteroviral infections. Early on, the CSF in patients with viral meningitis frequently contains a predominance of polymorphonuclear leukocytes and may even have a low glucose level. The presence of neutrophils in the initial CSF sample is especially common in patients with enteroviral infections. A CSF glucose level lower than 50 per cent of a simultaneously drawn blood glucose determination is not uncommon in patients with viral meningitis due to mumps, LCM, and herpes simplex. In a patient with a predominance of polymorphonuclear leukocytes in the initial CSF specimen and in whom a viral infection is suspected, antibiotics may be withheld if a spinal tap is repeated within 12 hours. A shift from polymorphonuclear leukocytes to mononuclear cells makes viral meningitis the likely diagnosis. Both herpes simplex and varicella-zoster may infect the meninges by means of spread from cervical and dorsal root ganglia in a retrograde fashion much the way they spread in an antegrade fashion to the skin. HSV-2 is more likely to cause the clinical syndrome of viral meningitis, while HSV-1 is more likely to cause a meningoencephalitis with serious brain dysfunction. The identification of a specific viral agent in body fluids, especially the CSF, in a patient with aseptic meningitis is of more than academic interest, since it can shorten duration of hospital stay and eliminate unnecessary antimicrobial therapy. The diagnosis of enteroviral infections depends upon the isolation of a virus from CSF, stool, or throat plus a fourfold antibody response in the serum to the viral isolate. The 60-odd serotypes of enterovirus, each with different antigenic determinants, preclude serologic testing alone as a useful diagnostic test to identify the patient infected with coxsackievirus or echovirus. For infections, due to herpes simplex, varicella-zoster, LCM, and arboviruses, a serologic test alone can be useful.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:3990441

K-ATP channel expression and pharmacological in vivo and in vitro studies of the K-ATP channel blocker PNU-37883A in rat middle meningeal arteries  

DEFF Research Database (Denmark)

Background and purpose: Dilatation of cerebral and dural arteries causes a throbbing, migraine-like pain, indicating that these structures are involved in migraine. Clinical trials suggest that adenosine 5'-triphosphate-sensitive K+ (K-ATP) channel opening may cause migraine by dilatating intracranial arteries, including the middle meningeal artery (MMA). We studied the K-ATP channel expression profile in rat MMA and examined the potential inhibitory effects of the K-ATP channel blocker PNU-37883A on K-ATP channel opener-induced relaxation of the rat MMA, using the three K-ATP channel openers levcromakalim, pinacidil and P-1075. Experimental approach: mRNA and protein expression of K-ATP channel subunits in the rat MMA were studied by quantitative real-time PCR and western blotting, respectively. The in vivo and in vitro effects of the K-ATP channel drugs on rat MMA were studied in the genuine closed cranial window model and in myograph baths, respectively. Key results: Expression studies indicate that inwardly rectifying K+ (Kir)6.1/sulphonylurea receptor (SUR) 2B is the major K-ATP channel complex in rat MMA. PNU-37883A (0.5 mg kg(-1)) significantly inhibited the in vivo dilatory effect of levcromakalim (0.025 mg kg(-1)), pinacidil (0.38 mg kg(-1)) and P-1075 (0.016 mg kg(-1)) in rat MMA. In vitro PNU-37883A significantly inhibited the dilatory responses of the three K-ATP channel openers in rat MMA at 10(-7) and 3 x 10(-7) M. Conclusions and implications: We suggest that Kir6.1/SUR2B is the major functional K-ATP channel complex in the rat MMA. Furthermore, we demonstrate the potent in vivo and in vitro blocking potentials of PNU-37883A on K-ATP channel opener-induced relaxation of the rat MMA Udgivelsesdato: 2008/5

Neonatal meningitis.  

Directory of Open Access Journals (Sweden)

The survey identifies Klebsiella pneumoniae and Serratia sp. as the leading bacterial agents of neonatal meningitis in our environment. The relatively high frequency of Serratia infection in the present survey appears unique as this organism is comparatively rare in other reports across the globe. No Group B Streptococcus was isolated, which is in contrast to reports obtained in Europe, America and Australia where it is the predominant organism of neonatal sepsis or meningitis. Antibiogram identified imipenem and cefotaxime as the empirical antibiotics in infants with a clinical diagnosis of neonatal sepsis in our hospital; no more conventional use of ampicillin. In view of the changing bacterial pattern of infant infection with time even in the same environment, a periodic review of this subject is advocated.

Microvasculature of the human cerebral meninges.  

Science.gov (United States)

In the present study, the human cerebral meninges were rich in blood vessels, but no capillaries were noted. The meningeal arteries ran over the veins where they crossed. Several arterial anastomoses existed on the cortical surface. The meningeal arteries were classified into four parts; the conducting artery approximately 700 microm in diameter, distributing artery approximately 200 microm in diameter, precortical artery approximately 60 microm in diameter and cortical artery approximately 30-40 microm in diameter. A single distributing artery supplied the area of approximately 3.5 x 2.0 mm on the brain surface. They further ramified into precortical arteries which stemmed cortical arteries. These precortical arteries had the distributing area of 1 mm2 and this distributing area was the same size as the width of human ocular dominant column of the visual cortex. Constriction, like a sphincter, was observed at the bifurcation of the distributing arteries. The cerebral blood vessels, which regulated the blood flow and reacted to autonomic nerve stimuli, seemed to correspond to the distributing arteries. PMID:12777101

The in vivo effect of VIP, PACAP-38 and PACAP-27 and mRNA expression of their receptors in rat middle meningeal artery  

DEFF Research Database (Denmark)

The parasympathetic nervous system is probably involved in migraine pathogenesis. Its activation releases a mixture of signalling molecules including vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase-activating polypeptide (PACAP), which subsequently stimulate VPAC(1), VPAC(2) and PAC(1) receptors. The objective of the present study was to investigate the in vivo effect of VIP, PACAP-27, PACAP-38, the selective VPAC(1) agonist ([Lys15, Arg16, Leu27]-VIP(1-7)-GRF(8-27)) and a PAC(1) agonist, maxadilan on rat middle meningeal artery (MMA) diameter using the closed cranial window model. Selective antagonists were used for further characterization of the responses. Reverse transcriptase-polymerase chain reaction experiments were also conducted to determine expression of mRNA of PACAP receptors in the MMA. The results showed that VIP, PACAP-38, PACAP-27 and the VPAC(1) specific agonist evoked significant dilations with the rank order of potency; VIP = PACAP-38 > PACAP-27 = [Lys15, Arg16, Leu27]-VIP(1-7)-GRF(8-27). Significant inhibition of dilation was only observed for the VPAC(1) antagonist PG97-269 on PACAP-38-induced dilation of MMA. The VPAC(2) antagonist PG99-465 and PAC(1) antagonist PACAP(6-38) did not significantly block VIP- or PACAP-induced dilation. Expression of mRNA of all three receptors was detected in the MMA. In conclusion, the VPAC(1) receptor seems to be predominant in mediating MMA dilation.

Rickettsial meningitis.  

Science.gov (United States)

Rickettsial infections are common in southern Europe and the most frequent and lethal type is Mediterranean spotted fever, caused by Rickettsia conorii. The disease is usually characterised by the classical triad of fever, eschar and rash, and is generally a mild disease in children. Complications including neurological involvement are rarely described. We report an unusual case of meningitis in an 18-year-old man, presenting during summer with fever and persistent headache. The cerebrospinal fluid analysis revealed increased cellularity (107 cells/?L), hypoglycorrhachia (50% of glycaemia) and hyperproteinorrhachia (284 mg/dL). Rickettsial infection was confirmed by serology and the patient was treated with doxycycline, with a favourable outcome. The patient's pet squirrel and/or associated vectors might be involved in the transmission of Rickettsia spp. This case underlines the importance of a high clinical suspicion and the benefits of early empirical treatment when facing compatible epidemiological contexts.

Extracranial projections of meningeal afferents and their impact on meningeal nociception and headache.  

Science.gov (United States)

Headaches can be evoked by activation of meningeal nociceptors, but an involvement of pericranial tissues is debated. We aimed to examine a possible extracranial innervation by meningeal afferents in the rat. For in vivo neuronal tracing, dextran amines were applied to the periosteum underlying the temporal muscle. Labeling was observed 2 days later in the parietal dura mater, trigeminal ganglion, and spinal trigeminal nucleus with confocal and electron microscopy. In the hemisected rat head, extracellular recordings were made from meningeal nerve fibers. Release of calcitonin gene-related peptide (CGRP) from the cranial dura mater during noxious stimulation of pericranial muscles was quantified. In vivo capsaicin was injected into the temporal muscle while meningeal blood flow was recorded. In the parietal dura mater, labeled C- and A? fibers ramified extensively, accompanied the middle meningeal artery, and passed through the spinosus nerve into the maxillary and mandibular, but not the ophthalmic division of the trigeminal ganglion. Some fibers could be traced into the ipsilateral spinal trigeminal nucleus. Electrophysiological recordings revealed afferent fibers with mechanosensitive receptive fields both in the dura mater and in the parietal periosteum. Noxious stimulation of the temporal muscle caused CGRP release from the dura mater and elevated meningeal blood flow. Collaterals of meningeal nerve fibers project through the skull, forming functional connections between extra- and intracranial tissues. This finding offers a new explanation of how noxious stimulation of pericranial tissues can directly influence meningeal nociception associated with headache generation and why manual therapies of pericranial muscles may be useful in headaches.

Medicininduceret aseptisk meningitis  

DEFF Research Database (Denmark)

Drug-induced aseptic meningitis is a rare adverse effect of some drugs. We report a patient with four episodes of meningitis caused by ibuprofen. In all episodes the patient had taken ibuprofen for pain, and subsequently developed fever and cerebrovascular symptoms. Drug-induced meningitis cannot be distinguished from meningitis caused by other agents. Diagnosis is therefore based on close association between drug administration and onset of symptoms, as well as negative microbiology tests results, especially if previous episodes of drug-induced meningitis have occurred.

Localized basal meningeal enhancement in tuberculous meningitis  

Energy Technology Data Exchange (ETDEWEB)

Focal basal meningeal enhancement may produce a confusing CT picture in children with suspected tuberculous meningitis (TBM). To demonstrate the incidence, distribution and appearance of localized basal meningeal enhancement in children with TBM. CT scans of patients with definite (culture proven) and probable (CSF suggestive) TBM were retrospectively evaluated by two observers. Localized basal enhancement was documented as involving: unilateral cistern of the lateral fossa (CLF), unilateral sylvian fissure, unilateral CLF and sylvian fissure in combination, unilateral CLF and sylvian fissure with ipsi- or contralateral ambient cistern and isolated quadrigeminal plate cistern. The study included 130 patients with TBM (aged 2 months to 13 years 9 months). Focal basal enhancement was seen in 11 patients (8.5%). The sylvian fissure was involved most commonly, followed by the lateral fossa cistern. The ambient cistern was involved in three patients and the quadrigeminal plate cistern in one. Focal areas of enhancement corresponded to the areas of infarction in every patient. Focal basal meningeal enhancement is common (8.5%) in paediatric TBM. This must be kept in mind when evaluating CT scans in children presenting with focal neurological findings, seizures or meningism in communities where TBM is endemic. (orig.)

Meningitis in elderly patients.  

Science.gov (United States)

Meningitis is uncommon in elderly patients in emergency department (ED). The characteristics of bacterial meningitis (BM) and nonbacterial meningitis (NBM) occurring in older patients are compared. A prospective multicenter study was conducted in the EDs of three teaching hospitals. Consecutive adult patients (n=159) with a confirmed meningitis [cerebrospinal fluid (CSF) leukocyte count greater than 5 mm] were included in this study. Eighteen consecutive patients (11%) aged more than or equal to 60 years (median age of 67 years) presenting with confirmed meningitis were included. In the older group, the prevalence of BM was higher than in the younger group (50% vs. 11%, P<0.05). At admission in the ED, older patients experienced less typical symptoms of meningitis than the younger. Conversely, elderly patients presented more frequent signs of encephalitis. In older adults, CSF white blood cells count, CSF protein, and CSF/blood glucose ratio were different between NBM and BM. The causative species of BM were Streptococcus species other than pneumoniae in two episodes, and Streptococcus pneumoniae in two patients; the causative species of NBM were enterovirus in one episode, herpes simplex virus 1 in four (compared with the younger group, P<0.05), and varicella zoster virus in one. The prevalence of BM was higher in the older group than in the younger. Older patients experienced less typical symptoms of meningitis and more frequently signs of encephalitis, with a high prevalence of herpes simplex virus 1 meningitis. PMID:19525850

Meningitis retention syndrome  

Directory of Open Access Journals (Sweden)

Full Text Available A 50-year-old Caucasian woman presented with signs and symptoms of meningitis preceded by a 3 day history of flu-like symptoms and progressive difficulty with urination. Cerebrospinal Fluid (CSF analysis was consistent with aseptic meningitis. She was found to have a significant urinary retention secondary to atonic bladder. MRI of the brain and spine were normal and CSF-PCR (polymerase chain reaction was positive for HSV-2. Urinary retention in the context of meningitis and CSF pleocytosis is known as Meningitis Retention Syndrome (MRS. MRS is a rare but important complication of meningitis most commonly associated with HSV-2. Involvement of central pathways may have a role in the pathogenesis of MRS but this is poorly documented. MRS is different from Elsberg syndrome wherein patients display features of lumbosacral polyradiculitis or radiculomyelitis. Early treatment with antiviral therapy was associated with a favorable outcome in our patient.

The microvasculature of the human cerebellar meninges.  

Science.gov (United States)

The vascular architecture of the human cerebellar meninges was investigated. The surface meninges were poor in vasculature. In the sulci, the meninges were highly vascular but had few capillaries. The venous blood vessels gave long side branches at right angles to the parent vessels in a cruciform pattern, running horizontally along the cerebellar sulci. They were situated at the origin of the secondary or tertiary sulci. Anastomoses between these horizontal branches gave a crosshatched appearance. Short branches often extended to the bases of the sulci, terminating in T-shaped bifurcations with numerous tiny branches, like the roots of a tree. The arteries ran perpendicular to venous branches which were parallel to each other exclusively along the sagittal plane. These arteries bifurcated to straddle the horizontally running veins at the origin of the secondary or tertiary sulci. They gave off many small branches like teeth of a fork from each artery in the secondary or tertiary sulci after they bifurcated to straddle the venous branches and penetrated the cerebellar cortex at the bases of sulci. These fork-like ramifications in the bases of the sulci were most likely responsible for the ready development of pronounced ischemic state. They might also play an important role in the occurrence of ischemic damage at the bases of sulci in cases of severe generalized ischemia. PMID:12410382

[Hypervasopressinism during tuberculous meningitis].  

Science.gov (United States)

In tuberculous meningitis there is a disturbance of control involving hyponatraemia and increased urinary elimination of antidiuretic hormone resulting in hypersecretion of vasopressin. This inappropriate secretion of antidiuretic hormone should not be confused with the Schwartz-Bartter syndrome, which is reserved for paraneoplastic syndromes. The pathophysiology remains poorly understood but its recognition in cases of lymphocytic meningitis is improved as the correct diagnosis has precise therapeutic implications. PMID:1857833

Locations of cerebral infarctions in tuberculous meningitis  

International Nuclear Information System (INIS)

The locations of cerebral infarctions were studied in 14 patients with tuberculous meningitis (TBM) and 173 patients with noninflammatory ischemic stroke (IS). In patients with TBM, 75% of infarctions occurred in the 'TB zone' supplied by medial striate and thalamoperforating arteries; only 11% occurred in the 'IS zone' supplied by lateral striate, anterior choroidal and thalamogeniculate arteries. In patients with IS, 29% of infarctions occurred in the IS zone, 29% in the subcortical white matter, and 24% in (or involving) the cerebral cortex. Only 11% occurred in the TB zone. Bilaterally symmetrical infarctions of the TB zone were common with TBM (71%) but rare with IS (5%). (orig.)

MR imaging and angiography in tuberculous meningitis  

International Nuclear Information System (INIS)

MRI was performed on 26 patients with tuberculous meningitis, with particular reference to document the cranial nerve abnormalities. MR angiography (MRA) was performed in 20 of the patients. Meningeal enhancement in the basal cisterns or over the convexity of brain was seen in all patients; two show ependymal enhancement. Tuberculomas, single (3), multiple (12) or military (2) were detected in 17 patients. Of the 9 patients with cranial nerve palsies, 7 showed contrast enhancement with or without thickening of the involved nerve. Abnormality signal intensity of the involved nerve was seen on proton density and T2-weighted images in one of these patients. MRA revealed focal arterial narrowing in 10 patients, the vessels commonly affected being the terminal segment of the internal carotid artery and the proximal segments of the middle and anterior cerebral arteries. One patient also had a small aneurysm of the proximal middle cerebral artery. Infarcts, haemorrhagic (8) or bland (6), were detected in 14 patients; most were the basal ganglia and internal capsules, large middle or anterior cerebral arterial territory infarcts being seen in only two cases.

Cortical venous thrombosis – a rare complication of tuberculous meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available Occlusion of the central veins and sinuses occurs owing to thrombus, thrombophlebitis, or tumours. Cerebral venous thrombosis (CVT is less frequent than arterial thrombosis, but can produce a cascade of sequelae and may be fatal. The usual predisposing factors for CVT include infections, pregnancy and puerperium, hypercoagulable states, etc. Many infectious causes are related to CVT, but a review of literature showed only few cases related to tuberculosis. Vascular changes consisting of arterial narrowing with or without occlusion are frequently seen at autopsy in cases of tuberculous meningitis. We report one such case of tuberculous meningitis where the patient developed cortical venous thrombosis after 5 days of illness. She was treated empirically, initially, till confirmation of the diagnosis and later was put on antitubercular drugs along with prednisolone therapy and anticoagulation, which led to complete recovery. Thus, if treated aggressively and in time, tuberculous meningitis and its complications are completely curable.

A Case of Kawasaki Disease Presenting with Aseptic Meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available Early recognition and prompt treatment of Kawasaki disease(KD are essential to ensure a succesful outcome of the coronary artery involvement. However, some patients lack sufficient clinical signs to fulfill the diagnostic criteria, and this may lead to problems in diagnosing children presenting with atypical symptoms. Central nervous system involvement, including aseptic meningitis, can be a presenting feature of KD itself. In this article, we describe a 9-year-old boy who presented with an unusual onset of disease, characterized by fever, erythematous maculopapular rash, vomiting and abdominal pain. He was diagnosed as aseptic meningitis with an unusual onset of Kawasaki Disease (KD clinical pattern together with the echocardiographic coronary arteries anomalies. Since the cardiovascular sequelaes of the disease could be prevented by early diagnosis and effective drug therapy, KD should be considered in the differential diagnosis in children with fever, erythematous maculopapular rash and vomiting that may be associated with clinical features of aseptic meningitis.

CT in meningitis purulenta  

International Nuclear Information System (INIS)

Twenty nine infants with meningitis purulenta were classified into 5 groups according to CT findings in the acute stage: cerebral infarction group, subdural hygroma group, ventricular enlargement group, and a group of other diseases. In each group, clinical findings, surgical procedures and prognosis were evaluated. In the cerebral infarction group, although 3 of 4 patients underwent V-P shunt or subdural drainage, remarkable sequelae were found in all the cases. Of 4 subdural hygroma patients, 2 had subdural drainage, and 4 of 8 patients with ventricular enlargement underwent V-P shunt. All the patients of the two groups had favorable prognosis without any sequela. A patient with cerebral herniation in the group of other diseases died in its acute stage. Eleven infants without abnormal CT findings showed normal psychomotor development. (Ueda, J.)

Meningitis and unpaved roads.  

Science.gov (United States)

Access to health care may be influenced by a variety of factors including ones attributable to the individual as well as ones attributable to the health care system. One category frequently referred to is 'geographic' factors of distance and travel time. In the present study, a previously undescribed geographic factor--unpaved roads--is shown to be a clinically important barrier to access. Using a case-control format, children admitted with bacterial meningitis are shown to have traveled farther over unpaved roads to get to a clinic than matched controls seen at the same time. With control groups matched for age and similar pre-existing illness, the implication is that unpaved roads resulted in increased morbidity by reducing access. PMID:3563554

Spinal perineurial and meningeal cysts  

Science.gov (United States)

Perineurial cysts may be responsible for clinical symptoms and a cure effected by their removal. They do not fill on initial myelography but may fill with Pantopaque some time, days or weeks, after Pantopaque has been instilled into the subarachnoid space. Perineurial cysts arise at the site of the posterior root ganglion. The cyst wall is composed of neural tissue. When initial myelography fails to reveal an adequate cause for the patient's symptoms and signs referable to the caudal nerve roots, then about a millilitre of Pantopaque should be left in the canal for delayed myelography which may later reveal a sacral perineurial cyst or, occasionally, a meningeal cyst. Meningeal diverticula occur proximal to the posterior root ganglia and usually fill on initial myelography. They are in free communication with the subarachnoid space and are rarely in my experience responsible for clinical symptoms. Meningeal diverticula and meningeal cysts appear to represent a continuum. Pantopaque left in the subarachnoid space may convert a meningeal diverticulum into an expanding symptomatic meningeal cyst, as in the case described. Many cases described as perineurial cysts represent abnormally long arachnoidal prolongations over nerve roots or meningeal diverticula. In general, neither of the latter is of pathological significance. Perineurial, like meningeal cysts and diverticula, may be asymptomatic. They should be operated upon only if they produce progressive or disabling symptoms or signs clearly attributable to them. When myelography must be done, and this should be done only as a preliminary to a probable necessary operation, then patient effort should be made to remove the Pantopaque. Images PMID:5531903

Computed tomography of tuberculous meningitis  

International Nuclear Information System (INIS)

Recently, tuberculous meningitis has become rather rare except in areas where tuberculosis is still endemic. Six adolescents and young adults with tuberculous meningitis were evaluated by means of serial computerized tomography (CT), and the results were correlated with the findings of surgical specimens or autopsies. All cases showed meningeal irritation and fever at onset. CSF cultures revealed the presence of tuberculous bacilli. Four cases advanced rapidly to the clinical stage III and expired in a short period-between two weeks to one month from onset. On initial CT scanning, the disappearance of the basal cistern was a characteristic finding in all these cases. With the progression, an enhancement of the basal cistern on contrast injection, a localized hypodensity in adjacent parenchyma, and symmetrical ventricular dilatation appeared. Two autopsied cases showed tuberculous granulomas with purulent materials, thickened meninges, and caseous necrosis in the parenchyma around the basal cistern. The other two cases progressed rather slowly. CT findings at Stage II showed multiple enhanced spots in the basal subcortical area following contrast injection. Tuberculous granulomas were identified in these parts by means of explorative craniotomy. The authors point out the pathognomonic CT findings of tuberculous meningitis and emphasize the necessity of serial CT for the early detection and management of tuberculous meningitis.

Muchas de ellas se acompañan de otros microorganismos de la orofaringe de estos animales. Se presenta un caso de meningitis bacteriémica por P. multocida en una mu [...] jer de 86 años que convivía con siete gatos. Si bien no se documentó una infección de piel o de partes blandas, es posible que ésta haya pasado inadvertida inicialmente y que fuera la causa de la bacteriemia con impacto en meninges, o bien que la meningitis se haya producido luego de la colonización nasofaríngea (no demostrada). Los aislamientos de hemocultivos y de líquido cefalorraquídeo fueron identificados como P. multocida por medio de API 20NE, API 20E y Vitek 1. La cepa aislada presentó sensibilidad a penicilina, cefotaxima, levofloxacina y tetraciclinas, en coincidencia con lo descrito en la literatura. Abstract in english Human infections by Pasteurella multocida are usually associated with bites or scratches from dogs and cats. Many of them are accompanied by other oropharyngeal microorganisms of these animals. We herein present a case of bacteremic meningitis by P. multocida in an 86-year-old woman who was living w [...] ith seven cats. Even though no skin or soft tissue infection was recorded, it is possible that a mild infection had gone undetected and a subsequent bacteremia had impacted on the meninges, or that meningitis could have occurred after nasopharyngeal colonization (not demonstrated). The isolates obtained from blood cultures and cerebrospinal fluid were identified as P. multocida by API 20NE, API 20E, and Vitek 1. In agreement with findings in the literature, this strain was susceptible to penicillin, cefotaxime, levofloxacin and tetracyclines.

Mycobacterium Bovis Meningitis: Case Report  

Directory of Open Access Journals (Sweden)

Full Text Available Mycobacterium bovis is a zoonotic bacteria infecting human. Early diagnosis and initiation of therapy is important for prognosis. Here,we present a three-year-old boy treated for bacterial meningitis. Because of inadequate clinical improvement, advanced diagnostic techniques were used and M. bovis was isolated from the cerebrospinal fluid. The patient survived with minimal sequela after 18 months therapy. In children without immune deficiency M. bovis meningitis is rare. In order to diagnose this disease, the clinician should suspect and use advanced diagnostic techniques like DNA Fingerprinting Spoligotyping. This rare case is presented to draw attention to M. bovis infections for public health.

Naegleria meningitis : a rare survival.  

Directory of Open Access Journals (Sweden)

Full Text Available Acute amebic meningoencephalitis caused by free-living amebae naegleria fowleri is extremely rare and uniformly fatal with only seven survivals reported till date. An interesting case of naegleria meningitis diagnosed by wet mount cytology of cerebrospinal fluid (CSF and treated with amphoterecin B, rifampicin and ornidazole with complete recovery is presented. In cases of suspected pyogenic meningitis, if CSF staining, antigen detection or culture is negative for bacteria, a wet mount cytology of CSF for naegleria is suggested. Early treatment with amphoterecin B and rifampicin may improve survival.

Bacterial meningitis after MMR immunisation.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Two children developed bacterial meningitis within five days of measles-mumps-rubella (MMR) immunisation. Diagnosis was delayed because symptoms were attributed to the vaccine, although both had a raised C-reactive protein. Fever or rash within five days of MMR vaccination are unlikely to be due to the vaccine and a raised C-reactive protein suggests bacterial infection.

Meningitis as cochlear implant complication  

Directory of Open Access Journals (Sweden)

Full Text Available Over the last several decades, cochlear implantation has been fully proven as the treatment for profound hearing losses. The direct electrical stimulation of the spiral ganglion hair cells through the electrode inserted in the cochlear scala tympani is the essence of the cochlear implant (CI functioning. Modern technological development has introduced unexpected technical quality possibilities of the device itself, as well as coding strategies, which further enable improved patients' rehabilitation results. Nevertheless, in spite of cochlear implantation becoming a routine surgical procedure, which has been changing lives of thousands of profoundly deaf adults and children, it has possible complications. Though rare, these complications could lead to severe, even fatal consequences. Bacterial meningitis represents one of the most severe postoperative complications. In this article, our five-year experience with cochlear implantation is shown, compared to other, much bigger, experiences. Despite severity and a potentially fatal outcome of meningitis, it has rarely been seen, and the precise connection between surgical procedure and this complication is not yet clear. Do cochlear implants increase the risk of bacterial meningitis? Are deafness-associated factors predisposing the bacterial meningitis occurrence, independently from the implant? These are the questions that the Centers for Disease Control and Prevention (CDC, the Food and Drug Administration (FDA and the CI surgeons have been facing, as well as manufacturers and patients with their families.

Computed tomography in meningeal carcinomatosis  

Energy Technology Data Exchange (ETDEWEB)

CT findings of meningeal carcinomatosis were studied in 17 patients (seven with lung cancer, two with breast cancer, one with gastric cancer, one with malignant melanoma, five with leukemia, and one with malignant lymphoma). The diagnosis was confirmed by a cytological survey of the cerebrospinal fluid and/or autopsy. Signs and symptoms caused by meningeal carcinomatosis at the CT examination varied from individual to individual. Those most frequently observed were signs of increased intracranial pressure, often accompanied by cranial nerve palsies, paresthesia, motor weakness, cerebellar signs, and nuchal stiffness, CT scan revealed evidence of meningeal carcinomatosis in ten cases out of the seventeen. CT evidences were obtained in 16.7% of the cases with hematologic malignancy and in 81.8% of those with non-hematologic malignancies. The CT findings of meningeal carcinomatosis may be summarized as follows: I. 1) Obliteration and narrowing of the cisterns and sulci, with contrast enhancement along them. 2) Enhanced spots/areas beneath the brain surface, with contrast enhancement. 3) Diffuse, slightly high density of the brain surface, with contrast enhancement. 4) Enhancement of the ventricular wall. 5) Hydrocephalus.

Multiple Cranial Nerve Involvement In Cryptococcal Meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available Cryptococcal meningitis is an uncommon cause of multiple cranial nerve palsies. This case report illustrates one such case of cryptococcal meningitis clinically manifesting with extensive cranial nerve involvement in an HIV seronegative individual. Histology revealed infiltration of the cranial nerves by cryptococci causing axonal disruption with secondary demyelination in the absence of any evidence of inflammation or vasculitis. We believe that axonal damage underlies the pathogenesis of cranial nerve involvement in cryptococcal meningitis.

Radiation in the treatment of meningeal leukemia  

International Nuclear Information System (INIS)

At the present time, a successful regimen for the eradication of occult meningeal leukemia is the combination of cranial radiotherapy in a dose of 1800 rads in 10 fractions in 12 to 14 days with six doses of intrathecal methotrexate. This regimen, when given with prednisone and vincristine can be expected to give a relapse rate for isolated meningeal leukemia of approximately 5% during the first 2 years of follow-up. A modification of this regimen utilizing craniospinal radiation with prior and concurrent intrathecal methotrexate is given for the treatment of overt meningeal leukemia at diagnosis or for an isolated first relapse with meningeal leukemia. Radiation technique and morbidity are discussed

Study of tuberculous meningitis by CT  

International Nuclear Information System (INIS)

Computed tomography is a very valuable method by which the pathogenic evolution of tuberculous meningitis may be followed, thereby facilitating its differential diagnosis and controlling the efficiency of therapy. The initial miliary tuberculosis in the brain, very often unaccompanied by neurological symptoms, may offer very evident CT images. CT may also demonstrate the fibrogelatinous exudate which fills the basal cisterns and surrounds the arterial vessels which cross this region. Because of this, secondary arteritis is frequent and may be indirectly detected by CT in the form of foci of ischemic infarcts. Tuberculomas may be multiple, and are found equally in the cerebral and the cerebellar parenchyma. These tuberculomas present different images on CT, depending on the evolution of the disease at that moment. Hydrocephalus is a common complication of TM and is caused by a lack of reabsorption of the cerebrospinal fluid, or by an obstructive lesion in the ventricular drainage pathways due to a tuberculoma. This complication is usually easily identified by CT, which, moreover, permits the control of its evolution. (orig.)

The       increase in incidence is probably caused by improved survival due to       improvements in systemic therapy and an increased awareness of MC among       clinicians. Diagnosis is based on CSF cytology and neuroimaging. MC is a       devastating condition that is associated with a poor prognosis, with a       median survival time of 4-11 weeks. The treatment is in most cases       palliative and involves radiotherapy and/or chemotherapy

Meningitis Caused by Pseudallescheria boydii.  

Directory of Open Access Journals (Sweden)

Full Text Available We present a 43-year-old immunocompetent man who developed meningitis caused byPseudallescheria boydii. The patient had no history of near drowning, trauma, steroidadministration, operations or any other underlying systemic disease. He presented withintermittent fever associated with headache, bilateral eye pain, and vomiting. Progressivehydrocephalus was noted during the course of the disease. Cerebrospinal fluid (CSF fromthe ventricular system allowed culture of the organism. Although the disease was diagnosedantemortemly, the patient died after antifungal treatment. This case is reported because ofthe unusual pathogen, unresponsiveness to amphotericin B combined with 5-fluocytocin,and immunocompetence of the patient without any predisposing factors.

Focal parenchymal lesions in community-acquired bacterial meningitis in adults: a clinico-radiological study  

Energy Technology Data Exchange (ETDEWEB)

Here, we analyzed the frequency, morphological pattern, and imaging characteristics of focal lesions as a consequence of community-acquired bacterial meningitis. We hypothesized that diffusion-weighted imaging combined with contrast-enhanced imaging, serial scanning, and multimodal vascular studies would provide further insight into the pathological basis of such parenchymal lesions in bacterial meningitis. We reviewed clinical and imaging data (i.e., magnetic resonance tomography, magnetic resonance angiography, computed tomography angiography, digital subtraction angiography) of 68 adult patients admitted to our neurological intensive care unit between March 1998 and February 2009 with the diagnosis of community-acquired bacterial meningitis. We identified seven patients with parenchymal lesions. These lesions could be attributed to four morphological patterns: (1) territorial cerebral ischemia, (2) perforating vessels ischemia, (3) ischemia of presumed cardiac origin, and (4) isolated cortical lesions. Whereas the patterns (1) and (2) were associated with vasculopathy of large- and medium-sized vessels (as shown by cerebral vascular imaging), vessel imaging in (3) and (4) did not show abnormal findings. Our study implies that parenchymal lesions in acute bacterial meningitis are mainly ischemic and due to involvement of large-, medium-, and small-sized arteries of the brain. Diffusion-weighted imaging combined with conventional, CT-, or MR-based cerebral angiography revealed the underlying pathophysiological mechanisms in the majority of patients. Furthermore, we detected two patients with isolated bilateral cortical involvement and normal vessel imaging. These lesions might represent ischemia due to the involvement of small pial and intracortical arteries. (orig.)

CT finding of cryptococcal meningitis  

International Nuclear Information System (INIS)

We have experienced 14 cases of cryptococcal meningitis in the last 6 years. Their neurological signs, CT findings, and prognoses were studied. They fall into three types: the brain-stem-encephalitis type, the cortical-encephalitis type, and the meningitis type, according to the clinical course. The first type (6 cases) revealed mainly cerebellar signs, eye-movement damage, and so forth. The second type (5 cases) demonstrated ''Personality'' changes, chiefly aphasia. The third type (5 cases) did not show any focal signs. Prognosis of the brain-stem-encephalitis type was very poor, with a 50% mortality rate. In the survivors, also, clinical signs did not disappear for a long time. Repeated CT was performed in 13 among the 14 cases; abnormal CT findings were revealed in 5 cases because of cryptococcal infection. Granuloma shadow and ventriculitis shadow were observed in 3 cases each. These abnormal findings disappeared upon treatment except in one case. The clinical signs are not completely related with the CT finding, but it is useful that the site which has been infiltrated by the cryptococcus can be observed. Abnormal CT findings were observed in the 4 cases of the brain-stem-encephalitis type among the 5 abnormal cases. It is very useful to know the severity of the condition. (author)

Supraglottitis and concurrent Hemophilus meningitis.  

Science.gov (United States)

Acute epiglottitis is a true pediatric emergency. The intense inflammation of the supraglottic larynx may completely obstruct the larynx within several hours. This infection is secondary to infiltration of Hemophilus influenzae type b (HIB), and 90% to 95% of patients have positive blood cultures. During this period of generalized septicemia HIB involvement of other soft tissue sites may occur. The goal of this article is to alert otolaryngologists to the possibility of extraepiglottitic HIB involvement. In particular, HIB meningitis, concurrent with supraglottitis, will be discussed. Although the overall incidence of multiple site involvement is relatively low, it is important to be aware of the possibility, since the outcome may be significantly altered. PMID:4051404

Differential vasoactive effects of sildenafil and tadalafil on cerebral arteries  

DEFF Research Database (Denmark)

Phosphodiesterase 5 (PDE5) is associated with migraine pathophysiology, stroke recovery and vasospasm treatment. The potential vascular interplay of PDE5 inhibitors sildenafil, tadalafil and UK-114,542 was studied by intra- versus extra-luminal administration in rat middle cerebral arteries in vitro and on middle meningeal arteries in vivo. By Western blot PDE5 was detected in both cerebral and meningeal arteries, though with minor variations in band intensity between vascular beds. Rat middle cerebral artery diameter was investigated using pressurised arteriography, applying UK-114,542, sildenafil, and tadalafil intra- or extra-luminally. Effects on the dural middle meningeal artery were studied in the in vivo closed cranial window model. At high concentrations, abluminal sildenafil and UK-114,542, but not tadalafil, induced dilatation of the middle cerebral artery. Luminal application elicited a contraction of 4% (sildenafil, P=0.03) and 10% (tadalafil, P=0.02). In vivo, sildenafil, but not tadalafil, dose-dependently dilated middle meningeal artery concomitant to blood pressure reduction (1-3mg/kg);1mg/kg sildenafil inducing 60 ± 14% (P=0.04) and vehicle (DMSO) 13 ± 6% dilatation. In conclusion, PDE5 inhibitors applied luminally had minor contractile effect, whereas abluminal sildenafil induced middle cerebral artery dilatation above therapeutic levels. In vivo, sildenafil dilated middle meningeal artery concomitant with a reduction in blood pressure. Tadalafil had no dilatory effects. PDE5 inhibitors show differential vascular activity in cerebral arteries from healthy animals; arterial dilatation is seen primarily above therapeutic levels. Such findings support clinical studies showing no vasodilator effects of sildenafil on cerebral arteries in healthy subjects.

Clinical research progress of tuberculous meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available Tuberculous meningitis is an infectious disease of central nervous system caused by Mycobacterium tuberculosis. It mainly invades into brain meninges and parenchyma, and may spread to the spinal cord and spinal meninges. The disability rate and mortality rate of this disease are very high. In recent years, incidence of tuberculosis increased significantly due to the increase of drug-resistant tuberculosis cases, population mobility, acquired immunodeficiency syndrome (AIDS epidemic and other factors. Tuberculosis is still a worldwide serious threat to human life and health, especially in the underdeveloped and developing countries. China is the world's largest developing country with large population, so tuberculosis prevention and control is still a quite severe problem. In this paper, the clinical manifestations, diagnosis and differential diagnosis, treatment progress of tuberculous meningitis were reviewed systematically. doi: 10.3969/j.issn.1672-6731.2014.08.004

Salmonella meningitis in an immunocompetent adult.  

Science.gov (United States)

Non-enteric salmonella infections in immunocompetent adults are exceedingly rare in the United States, and meningitis is one of the least common extra-intestinal sites. In addition, it is very unusual for a patient with bacterial meningitis to present with classic meningitis signs and symptoms of > 72 h duration. The objective of this work is to describe a rare case of salmonella meningitis in an immunocompetent adult and, in the context of previously published case reports, describe the frequently atypical clinical course of salmonella meningitis along with the potential pitfalls encountered during its evaluation and treatment. An otherwise healthy 45-year-old man presented to our Emergency Department with frontal headache, fever, and stiff neck of 7 days duration. He was alert and oriented in triage, where he was noted to be afebrile, mildly tachycardic, with a normal blood pressure and respiratory rate; shortly after triage he developed a high fever, severe tachycardia, hypotension, and a change in mental status. He was resuscitated according to our severe sepsis protocol and treated empirically for bacterial meningitis. Blood and cerebrospinal fluid cultures grew group D Salmonella berta. An evaluation for underlying immunodeficiency was unrevealing. The patient was discharged home on hospital day 7 in good condition. Salmonella meningitis can present with an indolent course and can mimic, in many misleading ways, the less serious diagnosis of aseptic meningitis. This case highlights the need for an unbiased clinical assessment, aggressive management of critical illness, and point-for-point correspondence between clinical data and assigned diagnosis.

TRANSETHMOIDAL MENINGOCELE AND RECURRENT MENINGITIS. CASE REPORT  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: Transethmoidal meningoceles are rare. The diagnosis is usually delayed and often made by the presence of recurrent meningitis.Case report: A 10-year boy with history of recurrent pneumococcal meningitis. Nasal endoscopy: mass in the right nostril between middle turbinate and septum. CT: soft tissue density lesion with disruption of the cortex adjacent to the "crista gali". MRI: cystic component injury with pedicle in anterior cranial fossa. Right frontal craniotomy was performed, removing meningocele with exit point on the cribriform plate,posterior dural closure, bone itself and scalp. Pathologic Study: fibrovascular tissue as an aspect membranes and glial tissue. Discussion: Intranasal meningocele is a rare malformation characterized by herniation of the meninges into the nasal cavity through a defect in the cribriform plate, due to a congenital abnormality, but also secondary to trauma or chronic intracranial hypertension. More common in certain geographic areas, especially in Southeast Asia. Usually cause nasal obstruction with or without recurrent meningitis. Differential diagnosis must be made with dermoid cyst, hemangioma, glioma and nasal polyp. CT and MRI are essential in the diagnosis and should precede the biopsy. The treatment is surgical or endoscopic nasal intracranial approach. Conclusions: In the presence of recurrent acute meningitis, it is necessary to rule out occult malformations of the skull base.

Meningeal enhancement on MRI after craniotomy  

Energy Technology Data Exchange (ETDEWEB)

Gd-DPTA-enhanced MR images in 94 patients who had undergone craniotomy were studied, with particular attention paid to the meningeal enhancement. Such enhancement was noted in 26 of the 94 (27.6%) in the portion surrounding the craniotomy site. Meningeal enhancement, presumably of the subdural neomembrane, was apparent as a third line of a high signal intensity on T{sub 1}-weighted MR images. The outer two high-intensity lines were derived from fat in the subcutaneous tissues of the scalp and fat in the bone marrow of the calvaria. We designated this characteristic enhancement as a 'triple white line'. Of the 26 patients with meningeal enhancement, 22 cases (23.4%) showed such a 'triple white line', 11 cases (11.7%) showed falx enhancement, and 12 cases (12.8%) showed tentorial enhancement. The intervals between surgery and the appearance of the meningeal enhancement ranged from 4 days to 88 weeks. A small amount of bleeding into the dura-arachnoid interface induced by surgery might result in the subdural neomembrane, as has previously been reported. This neomembrane might be enhanced by the leakage of Gd-DTPA through the proliferating capillaries. As meningeal enhancement occurs in approximately a third of the cases following craniotomy, much care should be taken in the differential diagnosis of the infection, inflammation, and metastasis or dissemination of malignant brain tumors.

Pathophysiology of neonatal acute bacterial meningitis.  

Science.gov (United States)

Neonatal meningitis is a severe acute infectious disease of the central nervous system and an important cause of morbidity and mortality worldwide. The inflammatory reaction involves the meninges, the subarachnoid space and the brain parenchymal vessels and contributes to neuronal injury. Neonatal meningitis leads to deafness, blindness, cerebral palsy, seizures, hydrocephalus or cognitive impairment in approximately 25-50?% of survivors. Bacterial pathogens can reach the blood-brain barrier and be recognized by antigen-presenting cells through the binding of Toll-like receptors. They induce the activation of NF?B or mitogen-activated protein kinase pathways and subsequently upregulate leukocyte populations and express numerous proteins involved in inflammation and the immune response. Many brain cells can produce cytokines, chemokines and other pro-inflammatory molecules in response to bacterial stimuli, and polymorphonuclear leukocytes are attracted, activated and released in large amounts of superoxide anion and nitric oxide, leading to peroxynitrite formation and generating oxidative stress. This cascade leads to lipid peroxidation, mitochondrial damage and breakdown of the blood-brain barrier, thus contributing to cell injury during neonatal meningitis. This review summarizes information on the pathophysiology and adjuvant treatment of acute bacterial meningitis in neonates. PMID:23946474

Meningitis tras anestesia y analgesia espinal / Meningitis after spinal anesthesia and analgesia  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish El objetivo de esta revisión es una puesta al día en la etiología, diagnóstico, profilaxis y tratamiento de la meningitis tras anestesia y analgesia espinales. Aunque es una complicación mayor de esta técnica y su incidencia es baja, cada vez son más frecuentes los casos publicados en la literatura [...] médica. Según su etiología se les clasifica en meningitis sépticas, víricas y asépticas. Las meningitis sépticas son las más frecuentes, y en su etiología cada vez juega un papel más destacado como agente implicado el estreptococo salivarius. Como meningitis asépticas se clasifican aquellas en las que el cultivo de líquido cefalorraquídeo es negativo, con un periodo de latencia de síntomas inferior a seis horas, que pueden cursar con eosinofilia en el líquido cefalorraquídeo y unos niveles cercanos a la normalidad en la glucorraquia. Suelen tener buena respuesta y evolución con tratamiento antibiótico con vancomicina y cefalosporinas de tercera generación. Como profilaxis incidir en las medidas de asepsia, sobre todo en el uso de mascarilla facial para realizar la técnica, como práctica para disminuir la incidencia de gérmenes cuyo origen está en la cavidad oral y orofaringe. Asimismo podrían reducir la incidencia de meningitis las medidas de asepsia tales como el lavado de manos, uso de guantes y asepsia de la piel. La diferenciación entre meningitis séptica y aséptica se hará con mayor seguridad cuando se estandaricen las técnicas para detectar genoma bacteriano en el líquido cefalorraquídeo; actualmente se etiquetan como meningitis asépticas aquellas en las que el cultivo de líquido cefalorraquídeo es negativo y cuya tinción de Gram es negativa. Pese a que el pronóstico y evolución en rasgos generales de las meningitis tras anestesia y analgesia espinal es bueno, en comparación con las meningitis adquiridas en la comunidad, por la escasa virulencia de las bacterias implicadas (Estreptococo salivarius), hay descritos casos con mala evolución de meningoencefalitis supurativa que han llevado a la muerte en pocas horas. Abstract in english The objective of this review is an update on etiology, diagnosis, prevention and treatment of meningitis after spinal anesthesia and analgesia. Although it is a major complication of this technique and its incidence is low, there are more and more frequent cases in the medical literature. According [...] to its etiology are classified in septic meningitis, viral and aseptic. The septic meningitis are the most common, and its etiology increasingly plays a more prominent role as Streptococcus salivarius agent involved. Aseptic meningitis are classified as those in which cerebrospinal fluid culture is negative, with a latency period of symptoms less than six hours, which may present with eosinophilia in the cerebrospinal fluid and levels close to normal in the CSF glucose. They usually have good response and evolution with antibiotic treatment with vancomycin and third-generation cephalosporins. Prophylaxis influence the aseptic precautions, especially the use of a face mask to perform the technique, as practical to reduce the incidence of bacteria whose origin is in the oral cavity and oropharynx. They could also reduce the incidence of aseptic meningitis measures such as hand washing, use of gloves and skin antisepsis. The differentiation between aseptic meningitis and septic will more securely when standardize techniques for detecting bacterial genome in the cerebrospinal fluid, now labeled as aseptic meningitis those in which cerebrospinal fluid culture is negative and whose negative Gram stain. Although the prognosis and evolution in general features of meningitis after spinal anesthesia and analgesia is good, compared with community-acquired meningitis, the low virulence of the bacteria involved (Streptococcus salivarius), cases have been described with poor outcome suppurative meningoencephalitis have led to death within hours.

Como meningitis asépticas se clasifican aquellas en las que el cultivo de líquido cefalorraquídeo es negativo, con un periodo de latencia de síntomas inferior a seis horas, que pueden cursar con eosinofilia en el líquido cefalorraquídeo y unos niveles cercanos a la normalidad en la glucorraquia. Suelen tener buena respuesta y evolución con tratamiento antibiótico con vancomicina y cefalosporinas de tercera generación. Como profilaxis incidir en las medidas de asepsia, sobre todo en el uso de mascarilla facial para realizar la técnica, como práctica para disminuir la incidencia de gérmenes cuyo origen está en la cavidad oral y orofaringe. Asimismo podrían reducir la incidencia de meningitis las medidas de asepsia tales como el lavado de manos, uso de guantes y asepsia de la piel. La diferenciación entre meningitis séptica y aséptica se hará con mayor seguridad cuando se estandaricen las técnicas para detectar genoma bacteriano en el líquido cefalorraquídeo; actualmente se etiquetan como meningitis asépticas aquellas en las que el cultivo de líquido cefalorraquídeo es negativo y cuya tinción de Gram es negativa. Pese a que el pronóstico y evolución en rasgos generales de las meningitis tras anestesia y analgesia espinal es bueno, en comparación con las meningitis adquiridas en la comunidad, por la escasa virulencia de las bacterias implicadas (Estreptococo salivarius), hay descritos casos con mala evolución de meningoencefalitis supurativa que han llevado a la muerte en pocas horas. Abstract in english The objective of this review is an update on etiology, diagnosis, prevention and treatment of meningitis after spinal anesthesia and analgesia. Although it is a major complication of this technique and its incidence is low, there are more and more frequent cases in the medical literature. According [...] to its etiology are classified in septic meningitis, viral and aseptic. The septic meningitis are the most common, and its etiology increasingly plays a more prominent role as Streptococcus salivarius agent involved. Aseptic meningitis are classified as those in which cerebrospinal fluid culture is negative, with a latency period of symptoms less than six hours, which may present with eosinophilia in the cerebrospinal fluid and levels close to normal in the CSF glucose. They usually have good response and evolution with antibiotic treatment with vancomycin and third-generation cephalosporins. Prophylaxis influence the aseptic precautions, especially the use of a face mask to perform the technique, as practical to reduce the incidence of bacteria whose origin is in the oral cavity and oropharynx. They could also reduce the incidence of aseptic meningitis measures such as hand washing, use of gloves and skin antisepsis. The differentiation between aseptic meningitis and septic will more securely when standardize techniques for detecting bacterial genome in the cerebrospinal fluid, now labeled as aseptic meningitis those in which cerebrospinal fluid culture is negative and whose negative Gram stain. Although the prognosis and evolution in general features of meningitis after spinal anesthesia and analgesia is good, compared with community-acquired meningitis, the low virulence of the bacteria involved (Streptococcus salivarius), cases have been described with poor outcome suppurative meningoencephalitis have led to death within hours.

Rheumatoid meningitis presenting with stroke-like episodes.  

Science.gov (United States)

Neurologic symptoms in patients with rheumatoid arthritis (RA) are most often caused by osseous compression, affecting the cervical spine or peripheral neurologic structures. CNS involvement in RA is infrequent, consisting of CNS vasculitis or meningitis with or without meningeal nodules.(1) When meningeal infiltration is seen, symptoms of presentation can include focal neurologic deficits, seizure, cranial nerve dysfunction, or altered consciousness.(1) Here we describe a patient with an unusual presentation of rheumatoid meningitis.

Use of radiologic modalities in coccidioidal meningitis  

International Nuclear Information System (INIS)

The diagnostic utility of pentetate indium trisodium CSF studies, technetium Tc 99m brain scans, and computerized tomographic (CT) scans was evaluated in eight patients in whom coccidioidal meningitis developed following a dust storm in the Central Valley of California. The 111In flow studies and the CT scans demonstrated hydrocephalus in five patients with clinical findings suggesting this complication. Ventriculitis has not previously been diagnosed before death in patients with coccidioidal meningitis; however, it was demonstrated in two patients by the technetium Tc 99m brain scan. The finding that communicating hydrocephalus occurs early in meningitis and interferes with CSF flow into infected basilar regions has important therapeutic implications in that antifungal agents injected into the lumbar subarachnoid space may not reach these regions

Neurosonographic findings of bacterial meningitis in Infants  

International Nuclear Information System (INIS)

44 infants under 1 year were studied retrospectively during these illness and follow up after 1 week intervals. The spectrum of sonographic features of bacterial meningitis in acute stage included normal scan (20 patients), echogenic sulci (10 patients), echogenic lining of epandymas (8 patients), Abnormal parenchymal echogenecity (6 patients). On follow up examination with 1 week intervals, variety of complications was found in 14 patients (32%) of the infants. There were ventriculomegaly in 7 patients, extraaxial fluid collection in 4 patients, brain abscess in 2 patients and poor encephalic cyst in 1 patient. We conclude that ultrasound was an effective method for evaluation of progression and complications of bacterial meningitis

Tuberculosis meningitis presenting as isolated interhemispheric exudates  

International Nuclear Information System (INIS)

Full text: The total number of tuberculosis cases in the world is increasing, and less common forms of tuberculous meningitis (TBM) with varying imaging manifestations are being encountered more often. We describe anterior interhemispheric variety of TBM, which has not been previously described to the best of our knowledge in the literature. Common imaging findings in these five patients include predominant involvement of the meninges in the anterior interhemispheric fissure with relatively little enhancement of the basal cisterns. Knowledge of uncommon radiological findings is vital in early diagnosis and treatment of this common disease.

Mondini dysplasia presenting as otorrhea without meningitis.  

Science.gov (United States)

Mondini dysplasia is a rare inner ear malformation that is usually only diagnosed after recurrent meningitis. Surgical intervention is mandatory. This report highlights the case of a patient with Mondini dysplasia who presented with hearing impairment and otorrhea and was diagnosed and treated before the occurrence of meningitis, thus preventing morbidity and neurologic sequelae. Hearing impairment may be the only manifestation of Mondini dysplasia, and the benefit of hearing screening is emphasized. Temporal bone computed tomography should be considered in children with unilateral sensorineural or mixed-type hearing impairment. PMID:23276442

Meningeal involvement in Behcet's disease: MRI  

International Nuclear Information System (INIS)

Behcet's disease is a multisystem disease that involves the central nervous system up to half of cases. Presentation with neurologic symptoms occurs in 5 % of cases and cerebral venous thrombosis is one of its major manifestations. A feature not previously reported is progressive meningeal thickening with involvement of both optic nerves. We report a patient with cerebral venous thrombosis, meningeal thickening and contrast enhancement on MRI. This patient had two other unusual features: positive antineutrophil cytoplasmic antibodies and later development of central diabetes insipidus. (orig.)

MR demonstration of the meninges: Normal and pathological findings  

International Nuclear Information System (INIS)

The MR appearance of normal and pathological meninges was studied in 23 patients. Amongst twelve normals, T1-weighted images demonstrated the meninges as slightly hyperintense density structures (compared with CSF) which increased in signal intensity somewhat after the administration of gadolinium-DTPA. On T2-weighted images, the subarachnoid space and meninges were isointense. In eleven patients with inflammatory disease or tumourous infiltration of the meninges, abnormal findings were evident in the unenhanced images as well as after administration of gadolinium-DTPA. Compared with CT, MR proved greatly superior in the diagnosis of meningeal abnormalities. (orig.)

Radioactive bromide partition test in the diagnosis of tuberculous meningitis  

International Nuclear Information System (INIS)

The utility of the radioactive bromide partition test in differentiating tuberculous meningitis (TBM) from other forms of meningitis has been assessed. The test was carried out in 19 patients with TBM, 6 patients with partially treated pyogenic meningitis and 17 non-meningitis controls. Eighteen of the 19 TBM patients gave bromide partition ratio (BPR) value below 1.3 while the value was above this level in all control patients including partially treated meningitis. The results indicate that the test is useful in the differential diagnosis of TBM. (author)

Meningeal infiltration in recurrent nasopharyngeal carcinoma  

International Nuclear Information System (INIS)

Permeative infiltration of the meninges appears to be a distinct form of recurrent nasopharyngeal carcinoma (NPC). The present report of eight patients with recurrent NPC illustrates meningeal infiltration following basal foramina extension. Seven of the eight patients (88%) showed jugular foramen involvement. Three patients had concomitant infiltration of the foramen magnum. There was one patient showing spread through the foramen lacerum. Only four (50%) of these patients had clinically detectable tumour in the nasopharynx, while the other half showed deep submucosal recurrence with endoscopically unremarkable findings. Permeative meningeal infiltration appears to be a distinct form of NPC recurrence. It is important to recognize this phenomenon so as to optimize the treatment options. The imaging studies were reviewed and the following features were recorded: local nasopharyngeal recurrence, the manner of intracranial spread and site of meningeal infiltration. Four patients had only MRI, two had only CT and two patients had both CT and MRI. The presence or absence of intracranial tumour before treatment was also recorded. Two observers reviewed the images and results were arrived at by consensus. Copyright (1999) Blackwell Science Pty Ltd

Full Text Available Keisho Hirota1,2, Masayuki Akimoto1,3, Toshiaki Katsura21Department of Ophthalmology, Kyoto Medical Center, National Hospital Organization, 2Internal Medicine, Kyoto Medical Center, 3Clinical Research Center, Kyoto Medical Center, Kyoto, JapanPurpose: The report of a case of bilateral acute retinal necrosis after herpetic meningitis.Case report: A 47-year-old man was admitted with the chief complaint of persistent high fever and transient loss of consciousness. Although his general condition improved after intravenous acyclovir administration, the patient presented with visual loss in both eyes 4 days after admission. Visual acuity in his right eye was 20/200 and his left eye had light perception alone. Both eyes showed panretinal arteritis diagnosed as acute retinal necrosis. Panretinal photocoagulation was performed for both eyes. Progression of retinal detachment was prevented in both eyes; however, visual acuity of the left eye was totally lost because of neovascular glaucoma. Visual acuity of the right eye recovered to 20/20.Conclusion: Although cases of bilateral acute retinal necrosis have been reported after herpetic encephalitis, this condition is rare after herpetic meningitis. Prophylactic acyclovir therapy and early panretinal photocoagulation may prevent retinal detachment and improve the prognosis. Neurologists and ophthalmologists should be aware that not only herpetic encephalitis but also herpetic meningitis can lead to acute retinal necrosis within a very short interval.Keywords: acute retinal necrosis, herpetic meningitis, herpes simplex, varicella zoster virus

Bacteremia causes hippocampal neural apoptosis in experimental pneumococcal meningitis  

DEFF Research Database (Denmark)

ABSTRACT: BACKGROUND: Bacteremia and systemic complications both play important roles in brain pathophysiological alterations and the outcome of pneumococcal meningitis. Their individual contributions to the development of brain damage, however, still remain to be defined. METHODS: Using an adult rat pneumococcal meningitis model, the impact of bacteremia accompanying meningitis on the development of hippocampal injury was studied. The study comprised of the three groups: I. Meningitis (n=11), II. meningitis with attenuated bacteremia resulting from iv injection of serotype-specific pneumococcal antibodies (n=14), and III. uninfected controls (n=6). RESULTS: Pneumococcal meningitis resulted in a significantly higher apoptosis score 0.22 (0.18-0.35) compared to uninfected controls (0.02 (0.00-0.02), Mann Whitney test, P=0.0003). Also, meningitis with an attenuation of bacteremia by antibody treatment resulted in significantly reduced apoptosis (0.08 (0.02-0.20), P=0.01) as compared to meningitis. CONCLUSIONS: Our results demonstrate that bacteremia accompanying meningitis plays an important role in the development of hippocampal injury in pneumococcal meningitis.

Primary diffuse leptomeningeal gliomatosis mimicking tuberculous meningitis.  

Science.gov (United States)

Primary diffuse leptomeningeal gliomatosis is a disease with an aggressive course that can result in death. To date, 82 cases have been reported. Here, the case of a 3-year-old male patient presenting with strabismus, headache, and restlessness is reported. Physical examination revealed paralysis of the left abducens nerve, neck stiffness, and bilateral papilledema. Tuberculous meningitis was tentatively diagnosed, and antituberculosis treatment was initiated when cranial imaging revealed contrast enhancement around the basal cistern. Craniocervical magnetic resonance imaging (MRI) was performed when there was no response to treatment, and it revealed diffuse leptomeningeal contrast enhancement around the basilar cistern, in the supratentorial and infratentorial compartments, and in the spinal region. Primary diffuse leptomeningeal gliomatosis was diagnosed by a meningeal biopsy. PMID:24284232

Infratentorial subdural empyemas mimicking pyogenic meningitis.  

Science.gov (United States)

Infratentorial subdural empyema is an extremely rare condition which unfortunately mimics pyogenic meningitis in 75% of cases. While an ill-planned lumbar puncture in these cases may be fatal, an inadvertent delay in treatment may be detrimental to the outcome for the patient. We present a case of a young boy with long standing history of chronic suppurative otitis media (CSOM) presenting with an infratentorial empyema with features suggestive of pyogenic meningitis. We also review the available literature to further define the condition in terms of clinical features, treatment options, and outcome. A misdiagnosis of this condition with failure to institute appropriate surgical intervention and antibiotic therapy is potentially life threatening. We highlight this rare condition which requires a high degree of suspicion especially in the presence of associated risk factors. PMID:23914110

Treatment for meningeal carcinomatosis in breast cancer  

International Nuclear Information System (INIS)

Forty breast cancer patients with meningeal carcinomatosis were treated with a combined program of whole brain irradiation therapy with intrathecal and intraventricular methotrexate and citrovorum factor rescue. Responses were seen in 26 patients (65%); 13 patients (35%) failed to respond. The median survival time for the responding patients was six months, and for the nonresponders, one month. Factors affecting response and survival included pretreatment spinal fluid glucose, protein, and duration of CNS-related symptomatology prior to onset of therapy. In contrast, pretreatment CSF tumor cell count, CEA and initial CNS functional status did not appear to have prognostic significance. The authors conclude that following intensive therapy there can be much improvement in the quality of life and disease-free survival in breast cancer patients with meningeal carcinomatosis

Confirmed viral meningitis with normal CSF findings.  

Science.gov (United States)

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. PMID:25035443

Aseptic meningitis epidemic during a West Nile virus avian epizootic.  

Science.gov (United States)

While enteroviruses have been the most commonly identified cause of aseptic meningitis in the United States, the role of the emerging, neurotropic West Nile virus (WNV) is not clear. In summer 2001, an aseptic meningitis epidemic occurring in an area of a WNV epizootic in Baltimore, Maryland, was investigated to determine the relative contributions of WNV and enteroviruses. A total of 113 aseptic meningitis cases with onsets from June 1 to September 30, 2001, were identified at six hospitals. WNV immunoglobulin M tests were negative for 69 patients with available specimens; however, 43 (61%) of 70 patients tested enterovirus-positive by viral culture or polymerase chain reaction. Most (76%) of the serotyped enteroviruses were echoviruses 13 and 18. Enteroviruses, including previously rarely detected echoviruses, likely caused most aseptic meningitis cases in this epidemic. No WNV meningitis cases were identified. Even in areas of WNV epizootics, enteroviruses continue to be important causative agents of aseptic meningitis. PMID:14519244

Meningococcal meningitis in CSR: a preepidemic situation?  

Science.gov (United States)

Meningococcal meningitis has become a problem in many European countries, with epidemics occurring during the past 10-15 years. There have also been outbreaks in some non-European countries. The latest meningococcal meningitis epidemic recorded in the CSR (Czech Socialist Republic) occurred in 1953, with the morbidity reaching 14.8 per 100 000 population. After the mid 1950's there was a gradual decline in morbidity, the lowest value (0.3 per 100 000 population) being reached in 1974. Since 1975 there has been a continual rise in morbidity, the value notified for 1982 was 1.2 per 100 000 population. An analysis of the epidemiological situation in meningococcal meningitis in CSR for the past 30 years was performed. Different indicators of the onset of epidemics were evaluated. Shift in the age distribution of patients was found to be the most valuable sign of changing epidemiological situtation. An attempt was made to prognosticate mathematically its further development. The analysis of the epidemiological data suggests that CSR is in a preepidemic situation. This finding is all the more important because a change has been found in the serogroup and serotype patterns of Neisseria meningitidis strains isolated from cerebrospinal fluid. PMID:6431713

Daptomycin in experimental murine pneumococcal meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Daptomycin, a lipopeptide antibiotic, could be an alternative to vancomycin for treatment of pneumococcal meningitis. We determined the activity of daptomycin versus vancomycin, with dexamethasone as an adjuvant, in a murine model of pneumococcal meningitis. Methods Ninety-six 25–30 gram mice were inoculated intracisternally with serotype 3 Streptococcus pneumoniae modified by the integration of a luminescent lux operon. All mice were treated with either dexamethasone 1 mg/kg intraperitoneally every 6 hours alone or in combination with either vancomycin or daptomycin, also administered intraperitoneally. Serum antimicrobial concentrations were selected to approximate those achieved in humans. Following treatment, bioluminescence and cerebrospinal fluid (CSF bacterial concentrations were determined. Caspase-3 staining was used to assess apoptosis on brain histopathology. Results Sixteen hours post intracisternal inoculation, bacterial titers in CSF were 6.8 log10 cfu/ml. Amongst the animals given no antibiotic, vancomycin 50 mg/kg at 16 and 20 hours or daptomycin 25 mg/kg at 16 hours, CSF titers were 7.6, 3.4, and 3.9 log10 cfu/ml, respectively, at 24 hours post infection (p-value, Conclusion Daptomycin or vancomycin, when given in combination with dexamethasone, is active in the treatment of experimental pneumococcal meningitis.

Influence of the blood bacterial load on the meningeal inflammatory response in Streptococcus pneumoniae meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Despite bacteraemia is present in the majority of patients with pneumococcal, little is known about the influence of the systemic infection on the meningeal inflammatory response. Methods To explore the role of systemic infection on the meningeal inflammation, experimental meningitis was induced by intracisternal injection of ~1 × 106 CFU Streptococcus pneumoniae, type 3, and the 26 rabbits were either provided with ~1 × 106 CFU S. pneumoniae intravenously at 0 hour ("bacteraemic" rabbits, n = 9, immunized with paraformaldehyde-killed S. pneumoniae for 5 weeks prior to the experiment ("immunized" rabbits", n = 8, or not treated further ("control" rabbits, n = 9. WBC and bacterial concentrations were determined in CSF and blood every second hour during a 16 hours study period together with CSF IL-8 and protein levels. We also studied CSF and blood WBC levels in 153 pneumococcal meningitis patients with and without presence of bacteraemia. Results As designed, blood bacterial concentrations were significantly different among three experimental groups during the 16 hours study period (Kruskal Wallis test, P P > 0.05. Blood WBC decreased in bacteraemic rabbits between ~10–16 hours after the bacterial inoculation in contrast to an increase for both the immunized rabbits and controls (P P In patients with pneumococcal meningitis, no significant difference in CSF WBC was observed between patients with or without bacteraemia at admission (n = 103, 1740 cells/?L (123–4032 vs. n = 50, 1961 cells/?L (673–5182, respectively, P = 0.18, but there was a significant correlation between CSF and blood WBC (n = 127, Spearman rho = 0.234, P = 0.008. Conclusion Our results suggest that a decrease in peripheral WBC induced by enhanced bacteraemia in pneumococcal meningitis results in an attenuated CSF pleocytosis.

Mollaret meningitis: case report with a familial association.  

Science.gov (United States)

Mollaret meningitis is a syndrome characterized by recurrent bouts of meningitis that occur over a period of several years in an affected patient. Also known as recurrent lymphocytic meningitis, this entity involves repeated episodes of headache, stiff neck, fever, and cerebrospinal fluid pleocytosis. Herpes simplex virus type 2 is the most frequently implicated causative agent, and treatment involves the use of antiviral medications. We describe a case of Mollaret meningitis in a 47-year-old man who presented to the emergency department with his eighth episode of meningitis during a period of 20 years. Cerebrospinal fluid polymerase chain reaction testing for herpes simplex virus type 2 was positive, and further testing excluded other common viral, bacterial, and inflammatory causes of meningeal irritation. The patient's family history was significant for a brother who also had multiple episodes of aseptic meningitis during a period of several years. This represents the first published report of a possible familial association involving Mollaret meningitis. It is likely that Mollaret meningitis is underrecognized among emergency physicians, and improved recognition of this entity may limit unwarranted antibiotic use and shorten or eliminate unnecessary hospital admission.

Meningitis bacteriana y Pseudomonas aeruginosa: a propósito de un caso Bacterial meningitis and Pseudomonas aeruginosa: apropos of a case  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Se presentó un paciente de 54 años de edad con cuadro clínico de meningitis, que en el estudio del líquido cefalorraquídeo se aisló Pseudomonas aeruginosa. La meningitis por bacilos gramnegativos ha ido incrementándose desde la década de los años 70, con una mayor incidencia en niños pequeños. Dentro de este grupo de infecciones, la causada por Pseudomonas sp. por su poca frecuencia, resulta una rareza. La meningitis por Pseudomonas aeruginosa debe tenerse en cuenta por la severida...

Intra-arterial chemotherapy for bilateral retinoblastoma via left ophthalmic artery and right anterior deep temporal artery.  

Science.gov (United States)

A 12-month-old boy with a history of bilateral retinoblastoma refractory to systemic chemotherapy, laser therapy and cryotherapy, with excellent response to previous intra-arterial melphalan infusion, presents with active tumour deposits in the right eye. Repeat intra-arterial chemotherapy was recommended. Previous bilateral melphalan infusion was uneventful using flow-guided catheterisation technique. Direct catheterisation of the right ophthalmic artery was unsuccessful despite employment of several flow-guided and over-the-wire catheters. Superselective catheterisation of the ipsilateral middle meningeal artery was unable to identify an anastomotic connection to the ophthalmic artery; however, angiography of the anterior deep temporal artery identified an alternate route for chemotherapy infusion. The anterior deep temporal artery was successfully and safely catheterised to infuse chemotherapy into the ophthalmic artery. The anterior deep temporal artery is an important potential anastomotic connection to the ophthalmic artery that can be used safely and effectively for central retinal artery chemotherapy infusion for retinoblastoma treatment.

Molecular studies of BKCa channels in intracranial arteries: presence and localization  

DEFF Research Database (Denmark)

Large conductance calcium-activated potassium channels (BK(ca)) are crucial for the regulation of cerebral vascular basal tone and might be involved in cerebral vasodilation relevant to migraine and stroke. We studied the differential gene expression of mRNA transcript levels and protein expression of the BK(Ca) channel in rat basilar, middle cerebral, and middle meningeal arteries by reverse transcription polymerase chain reaction (RT-PCR), quantitative real-time PCR, and Western blotting. Distribution patterns were investigated using in situ hybridization and immunofluorescence studies. RT-PCR and quantitative real-time PCR detected the expression of the BK(Ca) channel mRNA transcript in rat basilar, middle cerebral, and middle meningeal arteries, with the transcript being expressed more abundantly in rat basilar arteries than in middle cerebral and middle meningeal arteries. Western blotting detected the BK(Ca) channel protein in rat basilar and middle cerebral arteries. In situ hybridization and immunofluorescence studies confirmed that the BK(Ca) channel mRNA and protein expression was localized to smooth muscle cells in all three intracranial arteries. The data thus suggest the presence and localization of both mRNA and protein expression of the BK(Ca) channel in the smooth muscle cell layer in rat basilar, middle cerebral, and middle meningeal arteries.

Adjuvant glycerol is not beneficial in experimental pneumococcal meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Bacterial meningitis in children causes high rates of mortality and morbidity. In a recent clinical trial, oral glycerol significantly reduced severe neurological sequelae in paediatric meningitis caused by Haemophilus influenzae type b, and a tendency towards a benefit of adjunctive glycerol was seen in pneumococcal meningitis. Methods Here we examined the effects of glycerol in pneumococcal meningitis of infant rats and adult mice. All animals received ceftriaxone, and glycerol or placebo. Brain damage, hearing loss, and inflammatory parameters were assessed. Results Clinically and by histopathology, animals treated with glycerol or placebo did not differ. While both groups showed equally high levels of matrix metalloproteinase-9 at 24 h after infection, a significant difference in favour of glycerol was observed at 40 h after infection. However, this difference in matrix metalloproteinase-9 in late disease did not result in an improvement of histopathologic parameters. Conclusion No benefit of adjunctive glycerol was found in these models of pneumococcal meningitis.

Cryptococcal meningitis in a goat – a case report  

Science.gov (United States)

Background Cryptococcus spp. are saprophytic and opportunistic fungal pathogens that are known to cause severe disease in immunocompromised animals. In goats there are reports of clinical cryptococcal pneumonia and mastitis but not of meningitis. Case presentation The following report describes a case of a five year old buck showing severe neurological signs, including paraplegia and strong pain reaction to touch of the hindquarters region. Treatment with antibiotics was unsuccessful and the animal was euthanized for humanitarian reasons. Postmortem examination revealed lumbar meningitis, lung nodules and caseous lymphadenitis lesions. Encapsulated Cryptococcus neoformans were identified from the lungs and meninges, showing that cryptococcal meningitis should be included in the differential diagnosis of goats showing paresis and hyperesthesia. The possibility of concurrent immunosuppression due to Corynebacterium pseudotuberculosis infection is raised. Conclusions Cryptoccocal meningitis should be included in the differential diagnosis list of goat diseases with ataxia and hyperesthesia. PMID:24708822

Meningeal sarcoma with rhabdomyoblastic differentiation: case report.  

Science.gov (United States)

A case of primary neoplasm of the meninges with unusual histological and clinical features, which occurred in a 61-year-old man is described. Although conventional light microscopy revealed an undifferentiated tumor consisting of small- to medium-sized elements, it did not allow any definitive histogenetic interpretation. Immunohistochemistry showed that the neoplastic cells were positive for actin, desmin, myoglobin, and vimentin, thus leading to the diagnosis of meningeal sarcoma with rhabdomyoblastic differentiation. This interpretation was also supported by electron microscopy, in dewaxed tissue samples, which revealed the presence of abortive Z-lines. It is noteworthy that retrospective microscopic examination of all the slides obtained both at initial presentation and at relapses demonstrated in some fields that the undifferentiated population was associated with typical meningiomatous features, as was also shown by the staining for the epithelial membrane antigen. Clinically, the tumor was characterized by an exceedingly long course (10 years). The histogenesis of the tumor and the diagnostic relevance of immunohistochemical techniques are discussed.

Directory of Open Access Journals (Sweden)

Full Text Available Problem statement: Post-Traumatic Meningitis (PTM is a serious complication followed trauma. It sounds to have different pattern and characteristics. The aim of the current study was to determine the characteristics and outcome of PTM in referral neurosurgery department in Iran. Approach: During 5 years period-2003-2008, all records from meningitis patients in neurosurgery department in the unique referral trauma center in Kerman, Iran were evaluated by researchers, retrospectively. The PTM cases were selected and their data registered in the data collection form. The outcome of the disease as live or death considered, too. Analysis was conducted based on outcome and multivariable ANOVA was done to determine factor associated with death in PTM cases. Results: The incidence of PTM in head trauma patients estimated 3.1% (95% CI = 2.5-3.9%. The most frequent cases were male 89.7%. Average of age was 28.4±17.2 years. Klebsiella was the most common organism in CSF culture. Hospital staying time average in these patients was 25.7±15.8 days. Surgery was done for 52 (66.6% cases. The fatality rate was 24.4%, (95% CI = 15.4-35.4. All death had undergone operation. Multivariable ANAOVA declared that blood sugar and CSF protein differed statistically between two groups, died and survived. Conclusion: PTM is an important phenomenon that has great mortality. Certainly, it needs antibiotic prophylaxis and immediate intervention and preventive services to reduce its morbidity and mortality rate.

Stages of tuberculous meningitis: a clinicoradiologic analysis  

International Nuclear Information System (INIS)

Objective: To determine the frequencies and percentages of various clinicoradiologic variables of tuberculosis meningitis (TBM) with reference to British Medical Research Council (BMRC) staging of the disease. Study Design: A case series. Place and Duration of Study: Department of Neurology, Jinnah Postgraduate Medical Centre, Karachi, from October 2010 to September 2011. Methodology: The study included 93 adult patients with the diagnosis of tuberculous meningitis (TBM) at the study place. Patients were divided in three groups according to British Medical Research Council (BMRC) staging of TBM. Different clinical and radiological findings were analyzed at different stages of the disease. Data was analyzed using SPSS (Statistical Package of Social Sciences) version 11.0. Results: A majority of patients were found to be in stage-II disease at the time of admission. History of illness at the time of admission was more than 2 weeks in 50% of stage-I patients but around 80% in stage-II and stage-III patients. Neck stiffness was the most commonly reported finding in all stages. Cranial nerve palsies were higher in stage-III (75%) than in stage-II (43%) and in stage-I (24%) patients. Hydrocephalus and basal enhancement was the most frequently reported radiographic abnormalities. Conclusion: Duration of illness and cranial nerve palsies are important variables in the diagnosis of TBM stages and if TBM is suspected, empiric treatment should be started immediately without bacteriologic proof to prevent morbidity and mortality.

International Nuclear Information System (INIS)

Objective: To explore the features of MRI in the patients with cryptococcus neoformans meningitis (CNM). Methods: All 10 cases with CNM in this group were examined with India-ink capsule staining of CSF. 9 cases were performed with contrast enhanced MRI head scan, 1 case performed with chest CT scan. Results: MRI features of CNM included: (1) There were no abnormalities on MRI plain scan in 2 cases, however with linear-like enhancement in cisterns and meninges after contrast. The leptomeninges and basal cisterns were often involved. (2) Multiple patch or flake-like longer T1 and T2 signals in bilateral basal ganglions, frontal, temporal and parietal lobes were displayed on MRI plain scan in 5 cases. And the lesions were enhanced like flake or no enhancement on contrast enhanced MRI. Basal and pre-pontine cisterns showed linear-like enhancement in 1 case. (3) Multiple round or oval shape longer T1 and T2 signals were occurred in the bilateral cerebral hemispheres, with nodular enhancement in 3 cases. (4) Hydrocephalus was found in 3 cases. Conclusion: CNM has high rate of misdiagnose, and the final diagnosis depend on pathology. Although MRI features of CNM lack specificity, MRI is of very important in the diagnosis and differential diagnosis of CNM. (authors)

Influence of the blood bacterial load on the meningeal inflammatory response in Streptococcus pneumoniae meningitis.  

DEFF Research Database (Denmark)

BACKGROUND: Despite bacteraemia is present in the majority of patients with pneumococcal, little is known about the influence of the systemic infection on the meningeal inflammatory response. METHODS: To explore the role of systemic infection on the meningeal inflammation, experimental meningitis was induced by intracisternal injection of approximately 1 x 10(6) CFU Streptococcus pneumoniae, type 3, and the 26 rabbits were either provided with approximately 1 x 10(6) CFU S. pneumoniae intravenously at 0 hour ("bacteraemic" rabbits, n = 9), immunized with paraformaldehyde-killed S. pneumoniae for 5 weeks prior to the experiment ("immunized" rabbits", n = 8), or not treated further ("control" rabbits, n = 9). WBC and bacterial concentrations were determined in CSF and blood every second hour during a 16 hours study period together with CSF IL-8 and protein levels. We also studied CSF and blood WBC levels in 153 pneumococcal meningitis patients with and without presence of bacteraemia. RESULTS: As designed, blood bacterial concentrations were significantly different among three experimental groups during the 16 hours study period (Kruskal Wallis test, P 0.05). Blood WBC decreased in bacteraemic rabbits between approximately 10-16 hours after the bacterial inoculation in contrast to an increase for both the immunized rabbits and controls (P < 0.05). The CSF pleocytosis was attenuated in bacteraemic rabbits as compared to the two other groups between 12-16 hours from time of infection (P < 0.017), despite accelerated CSF IL-8 levels in bacteraemic rabbits. In patients with pneumococcal meningitis, no significant difference in CSF WBC was observed between patients with or without bacteraemia at admission (n = 103, 1740 cells/microL (123-4032) vs. n = 50, 1961 cells/microL (673-5182), respectively, P = 0.18), but there was a significant correlation between CSF and blood WBC (n = 127, Spearman rho = 0.234, P = 0.008). CONCLUSION: Our results suggest that a decrease in peripheral WBC induced by enhanced bacteraemia in pneumococcal meningitis results in an attenuated CSF pleocytosis.

Selective angiography of the external carotid artery and branches  

International Nuclear Information System (INIS)

Selective angiography of the external cartoid artery and superselective angiography of single branches can be used for demonstration of blood supply of dural tumors, tumors of the skull, skull base and of facial parts o the skull. Especially malformations of vessels and their blood supply can be shown. Improvements in X-ray technique and apparatus enable movement angiography, which can be very helpful for the diagnosis of special changes. In special kinds of headache influences from outside to the external carotid artery, to the maxillary artery, to the ascending pharyngeal artery, to the posterior auricular artery, to the occipital artery and the meningeal branches can be of higher importance than was assumed before. Selective angiographies of the external carotid artery and radiographic investigations of the anatomical situation are giving the basis for planning of embolisations. For diagnosis of intra- and extracranial changes the neuroradiologist is the connecting person between all specialists for skull and brain. (orig.)

Viral etiology of aseptic meningitis among children in southern Iran.  

Science.gov (United States)

Aseptic meningitis refers to a clinical syndrome of meningeal inflammation in which bacteria cannot be identified in the cerebrospinal fluid (CSF). The viral etiology and the epidemiological, clinical, and laboratory characteristics of aseptic meningitis among children aged 2 months to 15 years in Shiraz, southern Iran were determined. From May 2007 to April 2008, 65 patients were admitted to the hospital with aseptic meningitis. Seven viruses, non-polio human enteroviruses, mumps virus, herpes simplex virus (HSV), varicella-zoster virus (VZV), human cytomegalovirus (HCMV), human herpes virus type 6 (HHV-6), and Epstein-Barr virus (EBV) were investigated by polymerase chain reaction (PCR) method. Viruses were detected in 30 (46.2%) patients in whom non-polio human enterovirus and mumps virus were detected in 13 (43.3%) and 11 (36.7%), respectively. The remaining 6 (20%) of the cases were caused by HSV, VZV, HCMV, and HHV-6. Haemophilus influenzae and non-polio human enterovirus were detected in one patient simultaneously. Viral meningitis was found to be more frequent during spring and summer. The majority (66.6%) of the patients were treated in the hospital for 10 days and had received antibiotics in the case of bacterial meningitis. Rapid diagnosis of viral meningitis using PCR testing of CSF can help shorten hospitalization, and avoid the unnecessary use of antibiotics. PMID:21412795

Meningitis registry of hospitalized cases in children: epidemiological patterns of acute bacterial meningitis throughout a 32-year period  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Bacterial meningitis remains a source of substantial morbidity and mortality in childhood. During the last decades gradual changes have been observed in the epidemiology of bacterial meningitis, related to the introduction of new polysaccharide and conjugate vaccines. The study presents an overview of the epidemiological patterns of acute bacterial meningitis in a tertiary children 's hospital during a 32-year period, using information from a disease registry. Moreover, it discusses the contribution of communicable disease registries in the study of acute infectious diseases. Methods In the early 1970s a Meningitis Registry (MR was created for patients admitted with meningitis in Aghia Sofia Children's Hospital in Athens. The MR includes demographic, clinical and laboratory data as well as treatment, complications and outcome of the patients. In 2000 a database was created and the collected data were entered, analyzed and presented in three chronological periods: A (1974–1984, B (1985–1994 and C (1995–2005. Results Of the 2,477 cases of bacterial meningitis registered in total, 1,146 cases (46.3% were classified as "probable" and 1,331 (53.7% as "confirmed" bacterial meningitis. The estimated mean annual Incidence Rate (IR was 16.9/100,000 for bacterial meningitis, 8.9/100,000 for Neisseria meningitidis, 1.3/100,000 for Streptococcus pneumoniae, 2.5/100,000 for Haemophilus influenzae type b (Hib before vaccination and 0.4/100,000 for Hib after vaccination. Neisseria meningitis constituted the leading cause of childhood bacterial meningitis for all periods and in all age groups. Hib was the second most common cause of bacterial meningitis before the introduction of Hib conjugate vaccine, in periods A and B. The incidence of bacterial meningitis due to Streptococcus pneumoniae was stable. The long-term epidemiological pattern of Neisseria meningitidis appears in cycles of approximately 10 years, confirmed by a significant rise of IR in period C. The Case Fatality Rate (CFR from all causes was 3.8%, while higher CFR were estimated for Streptococcus pneumoniae (7.5%, RR=2.1, 95% CI 1.2–3.7 and Neisseria meningitidis (4.8%, RR=1.7, 95% CI 1.1–2.5 compared to other pathogens. Moreover, overall CFR varied significantly among the three time periods (p = 0.0015, and was estimated to be higher in period C. Conclusion By using the MR we were able to delineate long-term changes in the epidemiology of bacterial meningitis. Thus the MR proved to be a useful tool in the study and the prevention of communicable diseases in correlation with prevention strategies, such as vaccinations.

Environmental enrichment restores cognitive deficits induced by experimental childhood meningitis  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english 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 artificia [...] l 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.

Not your "typical patient": cryptococcal meningitis in an immunocompetent patient.  

Science.gov (United States)

Meningitis, when caused by the fungal mycoses Cryptococcus neoformans, is normally seen in immuno-compromised hosts. However, immunocompetent patients are also susceptible to cryptococcal meningitis (CM). In patients with an intact immune system, CM usually presents with the typical signs and symptoms of meningitis: fever, stiff neck, and headache. Major implications for the primary and advanced practice nursing plans of care for CM patients include a thorough history and physical exam, early diagnosis and treatment, and an individualized plan of care focused on minimizing sequelae and side effects of treatment and maximizing functional recovery.

Cranial Nerve Palsy as a Factor to Differentiate Tuberculous Meningitis from Acute Bacterial Meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available Tuberculous meningitis (TBM and acute bacterial meningitis (ABM cause substantial mortality and morbidity in both children and adults. Identification of poor prognostic factors at patient’s admission could prepare physicians for more aggressive monitoring of patients with meningitis. The objective of this study was to determine the predictive value of neurological features to differentiate ABM and TBM. A retrospective study was conducted between patients affected with ABM or TBM admitted to three teaching hospitals during the last 14 years in Zahedan the central city of Sistan and Balouchestan province (Iran. The neurological features include seizure, level of consciousness, stroke, focal neurologic deficit and cranial nerve palsy at the time of admission. Mean age for patients with TBM and ABM were 41 ± 22.4 and 24 ± 18.5 years respectively. In univariate analysis, all measured variables revealed significant difference between ABM and TBM patients except for seizure episodes. Multivariate logistic regression analysis showed positive predictive effect of cranial nerve palsy (AOR=1.980, CI 95%: 1.161-3.376 on the diagnosis of TBM. In our study cranial nerve palsies was the most important neurological predictor factor to differentiate TBM from ABM

Vitamin B6 prevents cognitive impairment in experimental pneumococcal meningitis.  

Science.gov (United States)

Streptococcus pneumoniae is the relevant cause of bacterial meningitis, with a high-mortality rate and long-term neurological sequelae, affecting up to 50% of survivors. Pneumococcal compounds are pro-inflammatory mediators that induce an innate immune response and tryptophan degradation through the kynurenine pathway. Vitamin B6 acts as a cofactor at the active sites of enzymes that catalyze a great number of reactions involved in the metabolism of tryptophan, preventing the accumulation of neurotoxic intermediates. In the present study, we evaluated the effects of vitamin B6 on memory and on brain-derived neurotrophic factor (BDNF) expression in the brain of adult Wistar rats subjected to pneumococcal meningitis. The animals received either 10?µL of artificial cerebral spinal fluid (CSF) or an equivalent volume of S. pneumoniae suspension. The animals were divided into four groups: control, control treated with vitamin B6, meningitis, and meningitis treated with vitamin B6. Ten days after induction, the animals were subjected to behavioral tests: open-field task and step-down inhibitory avoidance task. In the open-field task, there was a significant reduction in both crossing and rearing in the control group, control/B6 group, and meningitis/B6 group compared with the training session, demonstrating habituation memory. However, the meningitis group showed no difference in motor and exploratory activity between training and test sessions, demonstrating memory impairment. In the step-down inhibitory avoidance task, there was a difference between training and test sessions in the control group, control/B6 group, and meningitis/B6 group, demonstrating aversive memory. In the meningitis group, there was no difference between training and test sessions, demonstrating impairment of aversive memory. In the hippocampus, BDNF expression decreased in the meningitis group when compared to the control group; however, adjuvant treatment with vitamin B6 increased BDNF expression in the meningitis group. Thus, vitamin B6 attenuated the memory impairment in animals subjected to pneumococcal meningitis. PMID:24903161

Cranial sonography plays an important role in the initial evaluation of infants with suspected bacterial meningitis and in monitoring for complications of the disease. Echogenic widening of the brain sulci, meningeal thickening and hyperemia suggest the diagnosis in an at-risk population. Sonography can identify the presence of extra-axial fluid collections, and color Doppler sonography can be very helpful in differentiating benign enlargement of subarachnoid spaces from subdural effusions.

Ambulant neuropsykologisk opfølgning af patienter indlagt med aseptisk meningitis  

DEFF Research Database (Denmark)

Aseptic meningitis is considered to be a benign illness with mild symptoms, and the prognosis is usually good. However, retrospective studies have demonstrated that these patients may experience cognitive sequelae. A neuropsychologist was affiliated to the Department of Infectious Diseases, and neuropsychological findings in patients with aseptic meningitis were assessed. In conclusion, at twelve months of follow-up cognitive dysfunction persist among the majority of patients; 75% had mental fatigue and 45% had changed their work status.

Find||Publications, data, projects, ... - OpenAIRE Every year West African countries within the Sahelo-Sudanian band are afflicted with major meningococcal meningitis (MCM) disease outbreaks, which affect up to 200,000 people, mainly young children, in one of the world's poorest regions. The timing of the epidemic year, which starts in February and ends in late May, and the spatial distribution of disease cases throughout the "Meningitis Belt" strongly indicate a close linkage between the life cycle...

Candida parapsilosis meningitis associated with Gliadel (BCNU) wafer implants.  

LENUS (Irish Health Repository)

A 58-year old male presented with meningitis associated with subgaleal and subdural collections 6 weeks following a temporal craniotomy for resection of recurrent glioblastoma multiforme and Gliadel wafer implantation. Candida parapsilosis was cultured from cerebrospinal fluid (CSF) and Gliadel wafers removed during surgical debridement. He was successfully treated with liposomal amphotericin B. To our knowledge, this is the first reported case of Candida parapsilosis meningitis secondary to Gliadel wafer placement.

Extensive Spinal Cord Injury following Staphylococcus aureus Septicemia and Meningitis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Bacterial meningitis is rarely complicated by spinal cord involvement in adults. We report a case of Staphylococcus aureus septicemia complicated by meningitis and extensive spinal cord injury, leading to ascending brain stem necrosis and death. This complication was investigated by magnetic resonance imaging which demonstrated intramedullary hyperintensity on T2-weighted images and by multimodality evoked potentials. Postmortem microscopic examination confirmed that the extensive spinal cord...

The use of magnetic resonance and MR angiography in the detection of cerebral infarction: A complication of pediatric bacterial meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available Bacground. Association of both cerebral infarction and acute bacterial meningitis is more common in younger patients than in the elderly. The rate of mortality and the frequency of sequel are very high inspite of the use of modern antibiotic therapy. In more than 30% of the cases of childhood bacterial meningitis, both arterial and venous infarctions can occur. The aim of this study was to present the role of the use of magnetic resonance (MRI, and MR angiography (MRA in the detection of bacterial meningitis in children complicated with cerebral infarctions. Method. In the Centre for MR, the Clinical Centre of Serbia, 25 patients with the diagnosis of bacterial meningitis, of which 9 children with cerebral infarction whose clinical conditon deteriorated acutely, despite the antibiotic therapy, underwent MRI and MR angiography examination on a 1T scanner. Examination included the conventional spin-echo techniques with T1-weighted saggital and coronal, and T2- weighted axial and coronal images. Coronal fluid attenuated inversion recovery (FLAIR and the postcontrast T1-weighted images in three orthogonal planes were also used. The use MR angiography was accomplished by the three-dimensional time-of-flight (3D TOF technique. Results. The findings included: multiple hemorrhagic infarction in 4 patients, multiple infarctions in 3 patients, focal infarction in 1 patient and diffuse infarction (1 patient. Common sites of involvement were: the frontal lobes, temporal lobes and basal ganglia. The majority of infarctions were bilateral. In 3 of the patients empyema was found, and in 1 patient bitemporal abscess was detected. In 8 of the patients MR angiography confirmed inflammatory vasculitis. Conclusion. Infarction is the most common sequel of severe meningitis in children. Since the complication of cerebral infarction influences the prognosis of meningitis, repetitive MRI examinations are very significant for the evaluation of the time course of vascular involvement. The use of MRI, especially FLAIR imaging, confirmed its value in the detection and determination of the site and the extent of cerebral infarction. Non-invasive technique of examination, 3D TOF MR angiography clearly should show the presence of inflammatory vasculitis.

Unique variation in the course of maxillary artery in infratemporal fossa: a case report.  

Science.gov (United States)

Maxillary artery is one of the key contents of the infratemporal fossa. Mandibular nerve and its branches form a clinically important relation of maxillary artery in this region. A comprehensive knowledge of variations of maxillary artery in the fossa is of special relevance in oral maxillofacial surgeries, management of epistaxis, intractable neuralgias or headaches. We found a unique variation of maxillary artery, presenting bilaterally, in relation to branches of mandibular nerve. During routine dissection in a 55-year-old male cadaver, maxillary artery was seen passing deep to lateral pterygoid muscle and crossed through the nerve loop formed between two roots of auriculotemporal nerve and posterior division of mandibular nerve. Further course of maxillary artery was medial to the posterior division of mandibular nerve. Maxillary artery gave its middle meningeal artery branch as it traversed through the nerve loop. A tortuous course taken by maxillary artery can lead to its entrapment causing headaches or nerve irritation presenting with neuralgia. PMID:23900508

FDG PET in the diagnosis of meningeal carcinomatosis  

International Nuclear Information System (INIS)

Objective: Meningeal involvement is frequent in metastatic lymphoma, leukemia, and other metastatic tumor. Functional signs may be misleading and the neurological examination may be normal or non-specific. Certain diagnosis requires identification of tumor cells in the cerebrospinal fluid. CSF cytology is however sometimes negative and MRI maybe help in providing the diagnosis. The aim of our retrospective study was to assess the role of FDG PET in the diagnosis of meningeal carcinomatosis. Patients and Methods: The diagnosis of meningeal carcinomatosis was made in 5 patients between 1999 and 2001. Two of the patients were suffer from lymphoma, two were lung cancer patients, and another was a breast cancer patient. Cytology examination of the cerebrospinal fluid provided the diagnosis of meningeal carcinomatosis in these 5 patients. All the patients had signs of neurological function impairment, but the neurological examination cannot demonstrate the site of lesions. Therefore, All the patients had MRI examination, but only 1 case was diagnosis correctly (the MRI showing meningeal enhancement). 3 patients' MRI results show normal .Another MRI was suspicious of ischemic change. Results: A brain FDG PET using an ECAT HR + PET examined all the 5 patients. All the FDG PET results show the hypermetabolic foci respectively. The foci were diffused on the brain meninges. Their size is bigger than the foci detected by MRI . 3 of the patients repeated the FDG PET scan after tretients repeated the FDG PET scan after treatment (chemotherapy and radiotherapy). The therapeutic effect can be reflecting by FDG PET (the foci dismissed as the neurological symptoms disappeared), although the simultaneity MRI shows no change before and after treatment. Conclusion: 5 patients proven meningeal carcinomatosis FDG PET has better sensitivity than brain MRI scans and other anatomic modality. The patients who suffer from metastatic lymphoma, leukemia, and other metastatic tumor with nonspecific neurological signs should be explored with a brain FDG PET

There have been limited studies done to rule out the cross-reactivity between these two causative parasites of EOM. This study aims to assess the specificity of the serological test in EOM by using each condition as a control for the other. Thirty-three patients with a diagnosis of EOM were enrolled. Sera from 22 patients with a positive 29-kDa antigenic diagnostic band of A. cantonensis were tested for the 21 and 24-kDa antigenic bands of G. spinigerum. Similarly, sera of 11 gnathostomiasis patients were tested for the 29-kDa diagnostic band for A. cantonensis. Only one patient in the angiostrongyliasis group had a positive result for the 21 and 24-kDa antigenic bands of G. spinigerum, while no gnathostomiasis patients showed a positive result for the 29-kDa antigenic band of A. cantonensis. The specificity of the 21 and 24-kDa antigenic bands for gnathostomiasis and the 29-kDa antigenic band for A. cantonensis was 95.5% and 100%, respectively. The antigenic bands for the diagnosis of gnathostomiasis and angiostrongyliasis in EOM were highly specific.

Carcinomatose das meninges: dados clínico-patológicos de 3 casos Carcinomatosis of the meninges: a report of three cases  

Directory of Open Access Journals (Sweden)

Full Text Available Foram estudados 3 casos de carcinomatose das meninges, autopsiados no serviço de Anatomia Patológica do Hospital Prof. Edgard Santos. O quadro neurológico apresentado era proeminente e representado por sinto- matologia decorrente do envolvimento meníngeo e encefálico, razão pela qual foram considerados como portadores de meningite tuberculosa e encefalomielite. O aspecto de maior interesse neste estudo foi a discrepância entre o quadro clínico e os dados anátomo-patológicos do exame do encéfalo. A sintomatologia clínica foi proeminente, enquanto as lesões anatômicas foram apenas discretas ou moderadas e representadas por espessamento e granulosidade das meninges, com infiltração difusa do espaço subaracnoideano pela neoplasia. Nos casos 1 e 3 a neoplasia estava representada por adenocarcinoma, cujos focos primitivos foram localizados no pulmão e vesícula biliar, respectivamente. O caso 2 era um carcinoma indiferenciado do estômago, com envolvimento difuso do espaço subaracnoideano e subdural, havendo neste último extensa hemorragia recente. Os critérios diagnósticos e a maneira de disseminação desta condição são discutidos.A diffuse involvement of the meninges by carcinoma is described in three cases characterizing the so called "meningeal carcinomatosis". The neurologic symptoms were those of the chronic meningitis or encephalomyelitis, with changes in the spinal fluid. The morphologic features were identical in the three cases and represented by slight to moderate thickening of the meninges by diffuse infiltration of tumor cells and few foci of inflamatory reaction. The cases 1 and 3 were represented by well differentiated adenocarcinoma with primary site in the lung and gallbladder, respectively. In case 2 the tumor was a poorly differentiated carcinoma of stomach with diffuse involvement of the arachnoid and dura mater associated with recent hemorrhage. An interesting point was the lack of correlation between clinical and pathological findings. The clinical symptoms were very prominent and the gross findings only slight to moderate. The criteria for diagnosis of this entity as well as the mechanism of dissemination of the carcinoma to the meninges are reviewed and discussed.

Clinical and microbiological features of cryptococcal meningitis  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english Introduction In this study, the clinical features, underlying diseases and clinical outcomes of patients with cryptococcosis were investigated. In addition, a molecular analysis of the Cryptococcus neoformans species complex isolated from these patients was performed. Methods A prospective study [...] of 62 cases of patients with cryptococcal infection was conducted at the Hospital de Doenças Tropicais de Goiás Dr. Anuar Auad from 2009-2010. Cryptococcal meningitis cases were diagnosed by direct examination and cerebrospinal fluid (CSF) sample culture. The profiling of these patients was assessed. The CSF samples were submitted to India ink preparation and cultured on Sabouraud dextrose agar, and C. neoformans was identified by the production of urease, a positive phenoloxidase test and assimilation of carbohydrates. C. neoformans and C. gattii isolates were distinguished by growth on L-canavanine-glycine-bromothymol blue medium, and molecular analysis was conducted via PCR fingerprinting reactions using M13 and (GACA)4 primers. Results From the 62 patients with cryptococcosis, 71 isolates of CSF were obtained; 67 (94.4%) isolates were identified as C. neoformans var. grubii/VNI, and 4 (5.6%) were identified as C. gattii/VGII. Of these patients, 53 had an HIV diagnosis. The incidence of cryptococcosis was higher among patients 20-40 years of age, with 74.2% of the cases reported in males. Cryptococcus-related mortality was noted in 48.4% of the patients, and the symptoms were altered sensorium, headache, fever and stiff neck. Conclusions The high morbidity and mortality observed among patients with cryptococcosis demonstrate the importance of obtaining information regarding the epidemiological profile and clinical course of the disease in the State of Goiás, Brazil.

Recent advances in the pathogenesis and pathophysiology of bacterial meningitis.  

Science.gov (United States)

Bacterial meningitis continues to account for worldwide morbidity and mortality despite the advent of effective bactericidal antibiotic therapy. Recent advances over the past 10 years in the development of experimental animal models as well as basic investigation into critical bacterial surface virulence factors have begun to clarify a conceptual framework for understanding the mechanism of meningitis development in humans. Basic observations regarding competing host defenses and bacterial virulence factors have supported a pathogenetic sequence of mucosal colonization with a meningeal pathogen; systemic host invasion with intravascular replication; blood brain barrier penetration and unimpeded CSF proliferation amid the impaired host defenses in the CSF milieu; and pathophysiologic sequelae including vasogenic, cytotoxic, and interstitial brain edema (and other processes) accounting for irreversible neuronal injury and death. Only through continued basic investigation into each of these pathogenetic steps will significant reductions in morbidity and mortality ensue. PMID:3535498

Computed tomography of granulomatous basal meningitis caused by pneumococcus  

International Nuclear Information System (INIS)

A case of 3-month-old female with ''granulomatous basal meningitis'' caused by pneumococcus was described. She suffered from high fever, vomiting, convulsion and loss of consciousness on January 28th, 1982. On admission the protein content of the spinal fluid was 280 mg/100 ml, the glucose 4 mg/100 ml and the cell count was 1206/3(L : 845, N : 361). Her symptoms and signs were deteriorated in spite of antibiotics and anticonvulsants. CT scan on the 10th day showed the enhanced basal cistern. She died on the 11th day but autopsy was not carried out. In this case, pneumococcus was cultured in CSF. This seemed to be the first case of ''granulomatous basal meningitis'' due to purulent meningitis in Japan. (author)

Meningitis associated with Vancomycin resistant Enterococcus casseliflavus: First report  

Directory of Open Access Journals (Sweden)

Full Text Available Enterococci are present in the gastrointestinal system as normal floral components. In the past two decades membersof the genus Enterococcus have emerged as important nosocomial pathogens worldwide. Enterococci may cause arange of different disorders such as urinary tract, intraabdominal, and wound infections, as well as endocarditis, meningitisand bacteraemia. Nosocomial enterococcal meningitis is most commonly observed following ventriculoperitonealshunt operations. Vancomycin resistant enterococcus (VRE represents 30% of all enterococci infections.This report presents a vancomycin-resistant Enterococcus casseliflavus meningitis case in a 66-year-old patient withventriculoperitoneal shunt, which has not been reported in the literature before. Successful outcomes were obtainedwith daptomycin plus linezolid combined treatment in VRE meningitis. Treatment recommendations in VRE meningitisare also discussed in this article.

Progress towards meningitis prevention in the conjugate vaccines era  

Directory of Open Access Journals (Sweden)

Full Text Available Acute bacterial meningitis is an important cause of morbidity and mortality among children less than five years old. Haemophilus influenzae, Streptococcus pneumoniae and Neisseria meningitidis are the most important agents of bacterial meningitis in developing countries. The development of the conjugate vaccines in the beginning of the 90's, especially type b H. influenzae (Hib, and more recently the heptavalent pneumococcal and the serogroup C meningococcal vaccines, have contributed directly to changes in the epidemiological profile of these invasive diseases (direct effect and of their carriage status (indirect effect. We review the impact of the Hib conjugate vaccine in Latin American countries, where this vaccine has been implemented, and the potential of pneumococcal and meningococcal conjugate vaccines for the reduction of meningitis worldwide. We also address constraints for the development and delivery of these vaccines and review new candidate state-of-the-art vaccines. The greatest challenge, undoubtedly, is to implement these vaccines worldwide, especially in the developing regions.

MR features in patients with residual paralysis following aseptic meningitis  

International Nuclear Information System (INIS)

MR studies were performed in three patients with paralysis in the lower extremities. Poliomyelitis-like paralysis can be caused by neurovirulent strains of nonpolioenteroviruses. Entervirus 71 (EV 71) is documented as one of the potentially neurovirulent strains and a causative agent of some epidemics (1-7). The clinical manifestations associated with the EV 71 infection include aseptic meningitis, hand-food-mouth disease (HFMD), acute respiratory illness and gastrointestinal disease(6). Although rarely fatal, flaccidparalysis can be followed by EV 71 induced aseptic meningitis. Anterior horn cell necrosis was suggested on MR in two patients with residual paralysis (7). MR features, however, have not yet been described in detail. In this report we present three cases of patients with clinical evidence of EV 71 induced aseptic meningitis whose MR studies showed residual changes in spinal cord

Multiplex PCR for rapid diagnosis of tuberculous meningitis.  

Science.gov (United States)

Rapid and specific diagnosis of tubercular meningitis is of paramount importance to decrease morbidity and mortality. The aim of the study was to evaluate multiplex PCR using protein b, MPB 64, and IS6110 primers directed against M. tuberculosis complex for the diagnosis of tuberculous meningitis (TBM). Multiplex PCR was performed on 18 TBM confirmed cases (culture was positive), 92 clinically suspected TBM cases and 100 non-TBM (control group) patients. Multiplex PCR had a sensitivity of 94.4% for confirmed cases and specificity of 100% for confirmed TBM cases. In 92 clinically diagnosed but unconfirmed TBM cases, multiplex PCR was positive in 84.78% cases. The overall sensitivity of microscopy, culture and multiplex cases were 1.81, 16.73, and 86.63% and specificity was 100, 100, and 100% respectively. Multiplex PCR using protein b, MPB 64, and IS6110 primers has a high sensitivity and specificity in diagnosis of tubercular meningitis. PMID:21455603

Full Text Available Mattew Clarke,1 Hilary Enuh,1 Jessie Saverimuttu,2 Jay Nfonoyim31Department of Medicine, 2Division of Infectious Disease, 3Critical Care Unit, Richmond University Medical Center, Staten Island, NY, USAAbstract: Group C Streptococcus (GCS is a rare cause of bacteremia in humans. It is mostly associated with zoonological infections. Although GCS can be part of the normal oral, skin, and genitourinary flora, an infection with this pathogen can be highly virulent, causing rapid, disseminating disease. With a mortality of about 25%, the poor prognosis is linked to the severity of illness and the high level of virulence of the organism. Only a few cases of GCS meningitis have been reported.

Meningeal carcinomatosis as first manifestation of gastric carcinoma  

International Nuclear Information System (INIS)

Meningeal carcinomatosis is defined as the malignant and widespread infiltration of the meninges due to the planting and growth of cancer cells within the leptomeningeal space. It occurs more frequently in patients with disseminated neoplastic disease, but it may occur after a disease free interval and may even be the first manifestation of cancer. The most common primary tumors in adults are breast (30-50%), lung (15-25%), melanoma (11%) and gastric cancer (0.16-0.69%); in marked contrast with pediatric cases in which lymphocytic leukemia is the most common. The following article describes an autopsy case of a patient with psychiatric symptoms, with no antecedents of importance, with progressive and fatal neurological impairment, whose pathological studies show meningeal carcinomatosis attributable to advanced gastric adenocarcinoma discovered de novo post mortem.

Spectrum of Meningitis in Adult at the Douala General Hospital  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: Describe the clinical, aetiological and prognostic features of infectious meningitis in adults at the Douala General Hospital (DGH. Patients and Methods: We carried out a 5-year retrospective cross-sectional study at the DGH, on data from the registers of the bacteriology and biochemistry laboratories. Cases of meningitis were identified from the results of the cerebrospinal fluid (CSF analysis, and the patient clinical file was obtained. Cases files of patients aged 15 years and above were included. For each patient, sociodemographic, clinical features and hospital mortality data were extracted. Results: During study period, 1877 CSF analyses were recorded and 135 were enrolled for data analysis. Up to 74 patients (55% were male and the mean age was 40.04 ± 12.5 years. The time lapse between the onset of symptoms and consultation was 12.24 ± 11.16 days. The main clinical signs were meningeal syndrome (96.3%, neck stiffness (71.1%, reduced alertness (64.4% and confusional states (55.6%. The main aetiology was bacterial (45.19% with Streptococcus pneumoniae (45.90% and Neisseria meningitis (29.51% leading. The other aetiologies were viral (21.48%, fungal with Cryptococcus neoformans (20% and meningeal tuberculosis (13.33%. Fifty eight patients (42.9% had a positive HIV serology. The mean duration of hospitalization was 9.05 ± 8.1 days, and the total in-hospital mortality was 25.18%. 117 patients (86.8% had received antibiotherapy before diagnosis. Conclusion: The clinical features of meningitis in the DGH are as in classical description. However, the mortality is high and the major aetiologies appear to be associated with HIV infection at least in part. Prospective multi-centric studies are needed to provide more evidence for the development of staged management guidelines in our resource-limited settings.

Outbreak of meningitis due to Serratia marcescens after spinal anaesthesia.  

Science.gov (United States)

This article describes an outbreak of meningitis caused by Serratia marcescens in patients who had undergone spinal anaesthesia for caesarean section. Bacterial meningitis was diagnosed in 12 of the 46 patients who underwent a caesarean section under spinal anaesthesia in a 75-bed private hospital between 6(th) and 14(th) March 2011. S. marcescens was isolated from samples taken from four prefilled syringes and one bag containing 5% dextrose with norepinephrine, suggesting that medications used in spinal anaesthesia were contaminated extrinsically. Strategies for prevention of anaesthesia-associated infections in operating theatres are discussed. PMID:24814159

Chryseobacterium indologenes is a rare cause of infection in infants. The majority of case reports belong to hospitalized infants with indwelling devices. We are presenting a rare case of Chryseobacterium indologenes meningitis in a healthy newborn with no neonatal intensive care unit admissions or indwelling devices. The pathogen is resistant to many antibiotics and the patient was successfully treated with cefepime. This is the first case of C. indolegenes meningitis presented in a newborn with no indwelling device, NICU or long-term broad spectrum antibiotics. The choice of antibiotics can be challenging since the pathogen may exhibit resistance to a number of antibiotics. PMID:23599885

Knowledge, attitudes, and practices related to meningitis in northern Ghana.  

Science.gov (United States)

Meningitis has a significant impact in the Sahel, but the mechanisms for transmission and factors determining a person's vulnerability are not well understood. Our survey examined the knowledge, attitudes, and practices of people in a meningitis-endemic area in the Upper East region of northern Ghana to identify social, economic, and behavioral factors that may contribute to disease transmission and possible interventions that might improve health outcomes. Key results suggest potential interventions in response to the risk posed by migration, especially seasonal migration, a lack of knowledge about early symptoms causing delayed treatment, and a need for further education about the protective benefits of vaccination.

Bilateral simultaneous hearing preservation mastoidectomy in otogenic meningitis.  

Science.gov (United States)

Bilateral simultaneous hearing conservation mastoidectomy has not been previously documented. We present our experience with this procedure. Three patients with pyogenic meningitis secondary to bilateral unsafe ears had hearing preservation surgeries of both ears in a single sitting. Although ear surgery carries risk of inner ear damage, in our series there was no deterioration of inner ear function in the 6 ears operated on. The air conduction threshold improved in 3 (50%) of the ears. When meningitis results from bilateral otogenic foci as in our series, simultaneous mastoidectomy in both ears may be the preferred method of treatment to eradicate the source of infection.

Los menores de 5 años aportaron la mayor carga global de años de vida ajustados por discapacidad y dentro de ellos S. pneumoniae el que generó la mayor carga. Conclusión: la carga por meningitis bacteriana resultó elevada y corroboró su alta utilidad para evaluar los problemas de salud.Introduction: bacterial meningitis is a real concern for physicians and general health systems of any country as well as the international bodies. Objective: to estimate burdens of disease from morbidity and mortality caused by bacterial meningitis in Cuba during 2006. Methods: the mortality and the incidence data of the epidemiological survey from the National Surveillance of Bacterial Meningitis of "Pedro Kourí" Institute of Tropical Medicine were used. The estimation methods were based on the WHO recommendations by using the DISMOD and the required Excel spreadsheets. Results: the global burden of bacterial meningitis was estimated at a total of 3527.26 Disability Adjusted Lost Years (DALYs, which accounted for 31.3 years lost per 100 000 inhabitants. Morbidity and mortality burden of bacterial meningitis without sequel weighing was 2056.25 disability adjusted lost years, being the 55.9 % caused by unidentified agent, followed by S. pneumoniae (30.9 %, N. meningitidis (9.5 % and H influenza type b (3.6 %. The mortality burden was 2 039 years of life lost from premature death, that is, 57.8 % of the global burden. Children under five years of age contributed the biggest global burden of disability adjusted lost years, and S. penumoniae generated the biggest burden. Conclusion: the burden of bacterial meningitis was high. Burden of disease is an important measure to assess health problems.

Using Relative Humidity Forecasts to Manage Meningitis in the Sahel  

Science.gov (United States)

Meningitis epidemics in the Sahel occur quasi-regularly and with devastating impact. In 2008, for example, eighty-eight thousand people contracted meningitis and over five thousand died. Until very recently, the protection provided by the only available vaccine was so limited and short-lived that the only practical strategy for vaccination was reactive: waiting until an epidemic occurred in the region and then vaccinating in that region to prevent the epidemic's further growth. Even with that strategy, there were still times when demand outpaced available vaccine. While a new vaccine has recently been developed that is effective and inexpensive enough to be used more broadly and proactively, it is only effective against the strain of bacteria that causes the most common kind of bacterial meningitis. As a result, there will likely be continued need for reactive vaccination strategies. It is widely known that meningitis epidemics in the Sahel occur only in the dry season. Our project investigated this relationship, and several independent lines of evidence demonstrate a robust relationship between the onset of the rainy season, as marked by weekly average relative humidity above 40%, and the end of meningitis epidemics. These lines of evidence include statistical analysis of two years of weekly meningitis and weather data across the Sahel, cross-correlation of ten years of meningitis and weather data in the Upper East region of northern Ghana, and high-resolution weather simulations of past meningitis seasons to interpolate available weather data. We also adapted two techniques that have been successfully used in public health studies: generalized additive models, which have been used to relate air quality and health, and a linearized version of the compartmental epidemics model that has been used to understand MRSA. Based on these multiple lines of evidence, average weekly relative humidity forecast two weeks in advance appears consistently and strongly related to the number cases of meningitis in the Sahel. Using currently available forecast models contributed through the WMO Thorpex-Tigge project, and applying quantile regression to enhance their accuracy, we can forecast the average weekly relative humidity to two weeks in advance which allows us to anticipate the end of an epidemic in a region of the Sahel up to four weeks in advance. This would allow public health officials to deploy vaccines to areas in which the epidemics are likely to persist due to continued dryness and avoid vaccinating in areas where the epidemics will end with higher humidity. Our presentation will conclude by introducing the relative humidity decision-information tool developed for use by public-health officials. We will also summarize the results of a weekly meningitis forecast exercise held during the 2011-2012 dry season with public health decision makers from several African countries and the World Health Organization. Finally, we highlight some results of concurrent socio-economic research that suggests other interventions for managing meningitis and helps quantify the economic impact of the disease in Ghana. Overall, while our research has demonstrated an actionable relationship between weather and disease, this relationship is only one factor in a complex and coupled human-natural system which merits continued investigation.

Cerebrospinal fluid CXCL13 is a prognostic marker for aseptic meningitis.  

Science.gov (United States)

In exceptional cases, patients with aseptic meningitis eventually develop aseptic meningoencephalitis. To find a candidate marker for the development of aseptic meningoencephalitis in adult patients diagnosed with aseptic meningitis, we compared 12 different cytokines/chemokines in cerebrospinal fluid (CSF) from 5 patients with aseptic meningoencephalitis, 8 patients with aseptic meningitis, and 8 patients with control disease. Only the CXCL13 concentration was significantly elevated in the CSF of the group with aseptic meningoencephalitis compared with the group with aseptic meningitis. Thus, CSF CXCL13 may be a useful marker for predicting the prognosis of aseptic meningitis. PMID:24907903

Full Text Available SciELO Cuba | Language: Spanish Abstract in spanish Objetivo: exponer las características clínicas y epidemiológicas de la meningitis aséptica, probablemente enteroviral, en recién nacidos atendidos en nuestro servicio de neonatología. Métodos: estudio retrospectivo de 291 pacientes recién nacidos ingresados en el servicio de neonatología del Hospita [...] l Pediátrico Universitario "Juan M. Márquez", entre los años 1992-2009, con el diagnóstico de meningitis aséptica. La información se obtuvo de una base de datos creada para una investigación sobre meningitis neonatal. Se analizaron diversas variables clínicas y epidemiológicas de presentación de esta enfermedad. Resultados: ocurrieron picos de incremento de la incidencia de la meningitis aséptica, con una tendencia estadísticamente significativa a disminuir en el transcurso de los 18 años (p= 0,00027). La frecuencia de presentación mostró una agrupación de casos hacia los meses de junio a noviembre. La fiebre estuvo presente en todos los pacientes, seguida por la irritabilidad y la presencia de diversas manifestaciones del aparato respiratorio. La apariencia de niño enfermo y las convulsiones fueron manifestaciones poco frecuentes. Exceptuando la pleocitosis, los indicadores convencionales en el líquido cefalorraquídeo y la relación glucosa líquido cefalorraquídeo/sangre tuvieron una mediana dentro de los límites normales para el período neonatal, sin embargo, los rangos fueron amplios. Hubo pacientes con pleocitosis importante, otros con predominio de los polimorfonucleares en una proporción mayor del 50 % y también con relación glucosa líquido cefalorraquídeo/sangre baja. La evolución clínica de todos los pacientes fue favorable sin secuelas neurológicas inmediatas aparentes. Conclusiones: los episodios de meningitis aséptica ocurridos siguen un patrón característico de las infecciones enterovirales con agrupación de casos estacional y picos epidémicos periódicos. La expresión clínica de la infección y los resultados en los exámenes de biometría hemática y del examen citoquímico del líquido cefalorraquídeo, aunque característicos de una infección de esta índole, tienen amplia variabilidad, pues puede haber pacientes que presenten hallazgos que se asemejan a los observados en pacientes con meningitis bacteriana, lo cual puede crear incertidumbre clínica al médico que evalúa el paciente. Abstract in english Objective: to show the clinical and epidemiological features of the aseptic meningitis, potentially by enterovirus in newborns seen in our service of Neonatology. Methods: a retrospective study was conducted in 291 neonatal patients admitted in the Neonatology service of the "Juan Manuel Márquez" Ch [...] ildren Hospital from 1992 to 2009, diagnosed with aseptic meningitis. Information was collected from a database created for a research on neonatal meningitis. Different clinical and epidemiological variables of presentation of this disease were analyzed. Results: there were peaks of increase in the incidence of the aseptic meningitis with a statistically significant trend to decrease within the 18 years old (p= 0.00027). The frequency of presentation showed a grouping of cases towards June to November. The fever was present in all patients, followed by irritability and presence of different manifestations of respiratory tract. The appearance of the sick child and the convulsions were no more frequent manifestations. Excepting for the pleocytosis, the conventional indicators in the cerebrospinal fluid/blood had a mean within the normal limits for the neonatal period, however, the ranks were wide. There were patients presenting with a significant pleocytosis, other with predominance of polimorphonuclear ones in a ratio higher than 50 % and also a low relation of glucose-cerebrospinal fluid/blood.

Full Text Available Bacground. Clinical manifestations caused by parvovirus B19 (PVB19 are various and depend on the age and immunity of an infected person. In children, the most frequent clinical manifestation of parvovirus B19 primary infection is erythema infectiosum (EI. Case report. In this case report we presented a 12-year-old patient with 2 clinical syndromes: erythema infectiosum and serous meningitis. Erythema infectiosum was manifested as fever, typical skin lesions (“slapped cheeks”, erythematous macules and papules confluent with reticular appearance on the extremities and the trunk. Serous meningitis had a mild course with an increased number of lymphocytes (120/ mm³ and the mildly increased level of proteins (0.75 g/l. The serological examination showed the presence of IgM and IgG antibodies against parvovirus B19 in serum, as well as in cerebrospinal fluid (CSF. The reduction of serum/CSF ratio of IgG antibodies was present. The symptomatic therapy was used in the treatment. The course and the prognosis were benign. Conclusion. Human PVB19, although non-specifically associated with CNS diseases could be an etiological factor that might cause serous meningitis. So, it should be considered in different diagnosis in patients with aseptic meningitis, especially during the outbreaks of erythema infectiosum.

Diagnostic features of tuberculous meningitis: a cross-sectional study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Tuberculous meningitis (TBM is a common central nervous system infection in the Philippines; however it is difficult to diagnose as findings are non-specific. Hence we decided to determine if, among patients with chronic meningitis syndrome, the following are associated with the diagnosis: new-onset seizures; focal neurologic deficit; pulmonary tuberculosis (PTB on chest X-ray; cerebrospinal fluid (CSF pleocytosis with lymphocytic predominance; decreased CSF glucose; increased CSF protein. Methods Adult patients with suspected TBM were enrolled after informed consent was obtained. Baseline physical examination and diagnostic tests including CT scan of the head with contrast and CSF analysis for acid fast bacilli (AFB smear, TB culture and cryptococcal antigen detection were done and results collected. Definite TBM was defined as positive AFB smear or positive TB culture or positive basal meningeal enhancement on CT contrast study. Logistic regression was done to determine which were associated with a diagnosis of TBM. Results 91 patients were included. Using the gold standard criteria mentioned above, 44 had definite TBM; but if subsequent clinical course and response to anti-Koch's therapy are considered, 68 had a final diagnosis of TBM. After logistic regression was performed, only abnormal CSF (the combination of CSF pleocytosis with lymphocytic predominance, decreased CSF glucose, and increased CSF protein was associated with the diagnosis of TBM. Conclusion In patients with chronic meningitis syndrome, only abnormal CSF was associated with the diagnosis of TBM.

Prognostic indicators in bacterial meningitis: a case-control study  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english This was a case-control study to identify prognostic indicators of bacterial meningitis in a reference hospital in Pernambuco/Brazil. The data were collected from charts of 294 patients with bacterial meningitis between January 2000 and December 2004. Variables were grouped in biological, clinical, [...] laboratory and etiologic agent/treatment. Variables selected in each step were grouped and adjusted for age. Two models were created: one containing clinical variables (clinical model) and other containing laboratory variables (laboratory model). In the clinical model the variables associated with death due to bacterial meningitis were dyspnea (p = 0.006), evidence of shock (p = 0.051), evidence of altered mental state (p = 0.000), absence of headache (p = 0.008), absence of vomiting (p = 0.052), and age >40 years old (p = 0.013). In the laboratory model, the variables associated with death due to bacterial meningitis were positive blood cultures (p = 0.073) and thrombocytopenia (p = 0.019). Identification of prognostic indicators soon after admission may allow early specific measures, like admission of patients with higher risk of death to Intensive Care Units.

Pulmonary cryptococcosis with cryptococcal meningitis in an immunocompetent host  

Science.gov (United States)

Cryptococcosis is a systemic fungal infection associated with significant morbidity and mortality. It predominantly affects people with immunosuppresion and human immunodeficiency virus infection. Extrapulmonary dissemination is rare in immunocompetent hosts. We present here a case of disseminated cryptococcosis in an immunocompetent patient who presented with an unusually large pulmonary mass and meningitis and successfully managed with medical therapy.

Meningeal carcinomatosis in small cell carcinoma of the lung  

International Nuclear Information System (INIS)

Small cell carcinoma of the lung is extremely sensitive to chemotherapy and radiation therapy. We describe the case of a patient who had a complete response to such treatment but relapsed with meningeal carcinomatosis. We propose that prophylactic therapy to the spinal cord as well as the brain should be considered in the treatment of patients with small cell carcinoma of the lung

Changing pattern of infectious agents in postneurosurgical meningitis  

Science.gov (United States)

Background: The rates of postneurosurgical infections, particularly meningitis and the most common pathogens have been reported variable during the recent years. The aim of this research was to determine the prevalence of postneurosurgical meningitis and its current spectrum of infectious agent. Methods: In a descriptive study, the postneurosurgical patients’ cerebrospinal fluid was cultured on blood and MacConkey agar plates and evaluated at Microbiology Laboratory. 55 significant isolates as species level were recognized by bacteriological techniques. Results: Acinetobacter baumannii (A. baumannii) was the most common organism [29(52.7%)], followed by Klebsiella pneumoniae [8(14.5%)], Methicillin-resistant Staphylococcus aureus [6(10.9%)], Staphylococcus saprophyticus [5(9.1%)], Pseudomonas aeruginosa [3(5.5%)], Methicillin-sensitive Staphylococcus aureus [3(5.5%)], and Enterococcus faecalis [1(1.8%)]. The majority of A. baumannii isolates were carbapenem-resistant. Conclusion: Our research revealed that the rate of postneurosurgical meningitis due to carbapenem-resistant A. baumannii has been increased. This finding emphasized the importance of preventive strategies against A. baumannii. The changing pattern of infectious agents in postneurosurgical meningitis over time suggests the necessity of other studies.

Outbreak of neonatal meningitis caused by Salmonella enterica serotype Worthington.  

Science.gov (United States)

We report an outbreak of Salmonella meningitis in a nursery unit due to serotype Worthington. The organism was isolated from blood and CSF samples of five babies. The isolates were found to be resistant to commonly used antibiotics such as ampicillin, cefotaxime, cefiriaxone and amikacin but were sensitive to ciprofloxacin. Serotype Worthington appears to be an emerging pathogen in neonatal units. PMID:15022937

Arterial embolism.  

Science.gov (United States)

Surgical and intensive care patients are at a heightened risk for arterial embolization due to pre-existing conditions such as age, hypercoagulability, cardiac abnormalities and atherosclerotic disease. Most arterial emboli are clots that originate in the heart and travel to distant vascular beds where they cause arterial occlusion, ischemia, and potentially infarction. Other emboli form on the surface of eroded arterial plaque or within its lipid core. Thromboemboli are large clots that dislodge from the surface of athesclerotic lesions and occlude distal arteries causing immediate ischemia. Atheroemboli, which originate from fracturing the lipid core tend to cause a process of organ dysfunction and systemic inflammation, termed cholesterol embolization syndrome. The presentation of arterial emboli depends on the arterial bed that is affected. The most common manifestations are strokes and acute lower limb ischemia. Less frequently, emboli target the upper extremities, mesenteric or renal arteries. Treatment involves rapid diagnosis, which may be aided by precise imaging studies and restoration of blood flow. The type of emboli, duration of presentation, and organ system affected determines the treatment course. Long-term therapy includes supportive medical care, identification of the source of embolism and prevention of additional emboli. Patients who experienced arterial embolism as a result of clots formed in the heart should be anticoagulated. Arterial emboli from atherosclerotic disease of the aorta or other large arteries should prompt treatment to reduce the risk for atherosclerotic progression, such as anti-platelet therapy and the use of statin drugs. The use of anticoagulation and surgical intervention to reduce the risk of arterial embolization from atherosclerotic lesions is still being studied. PMID:23724391

[Peripheral arteries].  

Science.gov (United States)

Peripheral arterial disease is a main cause of morbidity in industrialised countries. It chiefly affects older people. The most common causes are atherosclerosis and vasodilatatory abnormalities. In the presence of unexplained leg symptoms, peripheral arterial disease can be diagnosed or ruled out by non-invasive diagnostic methods such as history, clinical examination and the measurement of ankle and brachial artery pressure by Doppler ultrasound, as well as by calculating the ankle brachial index. Colour coded duplex sonography, computer tomography angiography, magnetic resonance angiography and arteriography are the imaging modalities used. Current diagnostic strategies are analysed for the different peripheral artery diseases. PMID:17479237

Carcinomatose das meninges: dados clínico-patológicos de 3 casos / Carcinomatosis of the meninges: a report of three cases  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese Foram estudados 3 casos de carcinomatose das meninges, autopsiados no serviço de Anatomia Patológica do Hospital Prof. Edgard Santos. O quadro neurológico apresentado era proeminente e representado por sinto- matologia decorrente do envolvimento meníngeo e encefálico, razão pela qual foram considera [...] dos como portadores de meningite tuberculosa e encefalomielite. O aspecto de maior interesse neste estudo foi a discrepância entre o quadro clínico e os dados anátomo-patológicos do exame do encéfalo. A sintomatologia clínica foi proeminente, enquanto as lesões anatômicas foram apenas discretas ou moderadas e representadas por espessamento e granulosidade das meninges, com infiltração difusa do espaço subaracnoideano pela neoplasia. Nos casos 1 e 3 a neoplasia estava representada por adenocarcinoma, cujos focos primitivos foram localizados no pulmão e vesícula biliar, respectivamente. O caso 2 era um carcinoma indiferenciado do estômago, com envolvimento difuso do espaço subaracnoideano e subdural, havendo neste último extensa hemorragia recente. Os critérios diagnósticos e a maneira de disseminação desta condição são discutidos. Abstract in english A diffuse involvement of the meninges by carcinoma is described in three cases characterizing the so called "meningeal carcinomatosis". The neurologic symptoms were those of the chronic meningitis or encephalomyelitis, with changes in the spinal fluid. The morphologic features were identical in the [...] three cases and represented by slight to moderate thickening of the meninges by diffuse infiltration of tumor cells and few foci of inflamatory reaction. The cases 1 and 3 were represented by well differentiated adenocarcinoma with primary site in the lung and gallbladder, respectively. In case 2 the tumor was a poorly differentiated carcinoma of stomach with diffuse involvement of the arachnoid and dura mater associated with recent hemorrhage. An interesting point was the lack of correlation between clinical and pathological findings. The clinical symptoms were very prominent and the gross findings only slight to moderate. The criteria for diagnosis of this entity as well as the mechanism of dissemination of the carcinoma to the meninges are reviewed and discussed.

The arterial blood supply of the temporomandibular joint: an anatomical study and clinical implications  

Energy Technology Data Exchange (ETDEWEB)

The aim of this study was to analyze three-dimensional images of the arterial supply to the temporomandibular joint. Ten patients (five men and five women, mean age 36 years) without signs or symptoms of temporomandibular disorders, who underwent contrast-enhanced computed tomographic (CT) scanning with intravenous contrast, were studied. The direct volume rendering technique of CT images was used, and a data set of images to visualize the vasculature of the human temporomandibular joint in three dimensions was created. After elaboration of the data through post-processing, the arterial supply of the temporomandibular joint was studied. The analysis revealed the superficial temporal artery, the anterior tympanic artery, the deep temporal artery, the auricular posterior artery, the transverse facial artery, the middle meningeal artery, and the maxillary artery with their branches as the main arterial sources for the lateral and medial temporomandibular joint. The direct volume rendering technique was found to be successful in the assessment of the arterial supply to the temporomandibular joint. The superficial temporal artery and maxillary artery ran along the lateral and medial sides of the condylar neck, suggesting that these arteries are at increased risk during soft-tissue procedures such as an elective arthroplasty of the temporomandibular joint.

K ATP channels in pig and human intracranial arteries  

DEFF Research Database (Denmark)

Clinical trials suggest that synthetic ATP-sensitive K(+) (K(ATP)) channel openers may cause headache and migraine by dilating cerebral and meningeal arteries. We studied the mRNA expression profile of K(ATP) channel subunits in the pig and human middle meningeal artery (MMA) and in the pig middle cerebral artery (MCA). We determined the order of potency of four K(ATP) channel openers when applied to isolated pig MMA and MCA, and we examined the potential inhibitory effects of the Kir6.1 subunit specific K(ATP) channel blocker PNU-37883A on K(ATP) channel opener-induced relaxation of the isolated pig MMA and MCA. Using conventional RT-PCR, we detected the mRNA transcripts of the K(ATP) channel subunits Kir6.1 and SUR2B in all the examined pig and human intracranial arteries. Application of K(ATP) channel openers to isolated pig MMA and MCA in myographs caused a concentration-dependent vasodilatation with an order of potency that supports the presence of functional SUR2B K(ATP) channel subunits. 10(-7) M PNU-37883A significantly inhibited the in vitro dilatory responses of the potent K(ATP) channel opener P-1075 in both pig MMA and MCA. In conclusion, our combined mRNA expression and pharmacological studies indicate that Kir6.1/SUR2B is the major functional K(ATP) channel complex in the pig MMA and MCA, and mRNA expression studies suggest that the human MMA shares this K(ATP) channel subunit profile. Specific blocking of Kir6.1 or SUR2B K(ATP) channel subunits in large cerebral and meningeal arteries may be a future anti-migraine strategy.

The angiographic demonstration of trauma to intracranial arteries  

International Nuclear Information System (INIS)

Damage to intracranial arteries was demonstrated angiographically in 24 patients with severe trauma to the skull and brain. The most common abnormalities were damage to the intima and traumatic carotid-cavernous fistulae (nine cases each). In addition, there were six traumatic aneurysms of the internal carotid artery, two extravasates from ruptured intracranial branches and one traumatic A-V fistula between the middle meningeal artery and the spheno-parietal sinus. The arterial damage was diagnosed either during the acute stage or after a latent period of days and weeks, if there were signs of intracranial bleeding or other evidence of vascular damage. Cerebral angiography in two or more projections is the method of choice for demonstrating even minor vascular lesions. (orig.)

Cerebrospinal Fluid Ferritin for Differentiation of Aseptic and Bacterial Meningitis in Adults  

Directory of Open Access Journals (Sweden)

Full Text Available Problem statement: Bacterial meningitis is one of the most important causes of mortality and morbidity. Rapid diagnosis of bacterial cause is very important and critical, because early antibiotic therapy prevents complications; different tests have been developed for rapid diagnosis of bacterial meningitis. One of them is CSF ferritin, which is evaluated in this study. Approach: During cross sectional study from 2008-2009 for 2 years, CSF was collects from 61 adults suspected to have meningitis. These patients admitted to Emam Reza and Sina hospitals of Tabriz. CSF was analyzed for ferritin, glucose, protein, cell count, culture and gram stains. Clinical data's were collected for all patients. Collected data?s were analyzed by SPSS software. Results: From 61 specimens, 19 cases had bacterial, 19 cases had aseptic meningitis and 23 cases had no criteria for diagnosis of meningitis. CSF ferritin in bacterial meningitis was 231.63 ± 61.26 ng dL?1 that was significantly higher, than that of aseptic meningitis group. Cut off value for ferritin was estimated 155ng dL?1 with sensitivity of 94% and specificity of 21.7% in this study. Symptoms such as levels of consciousness, fever and seizure were not considered as a criteria for diagnosis of bacterial meningitis (p>0.05. But symptoms such as headache, nausa, vomiting and neck stefness were significantly higher in bacterial and aseptic groups than no meningitis group (pConclusion: In this study CSF ferritin in bacterial meningitis group was significantly higher than aseptic meningitis group. But due to low specificity of CSF ferritin for differentiation of bacterial from aseptic meningitis, we don?t recommend performance of this test in early phase of meningitis course.

[Cryptococcus meningitis in an immunocompetent child: a case report].  

Science.gov (United States)

Cryptococcus meningitis is uncommon in childhood. We report a Senegalese case of cryptococcus meningitis diagnosed in an apparently immunocompetent child. A 9-year-old boy was admitted for acute meningoencephalitis. A computerized tomography scan of the brain showed an ischemic lesion in the left caudate and study of cerebrospinal fluid (CSF) revealed cytological and biochemical abnormalities and Cryptococcus neoformans on direct exam and culture. HIV and syphilis antibodies were negative and the blood CD4 lymphocyte count was 804/mm(3). The child had no immunocompromising factors such as hematologic abnormalities, solid tumor, or undernutrition. He was treated with fluconazole intravenously, but clinical outcome was unsuccessful. The patient died after 1 month from cardiovascular and respiratory distress. PMID:20400277

Case Report: Group B Streptococcus meningitis in an adolescent    

Science.gov (United States)

Streptococcus agalactiae (group B Streptococcus, GBS) usually colonizes the gastrointestinal and lower genital tracts of asymptomatic hosts, yet the incidence of invasive disease is on the rise . We describe a case of an 18 year old woman, recently diagnosed with lupus, who reported a spontaneous abortion six weeks prior to her hospitalization.  She presented with fever, altered mental status, and meningeal signs, paired with a positive blood culture for GBS. Magnetic resonance imaging of her brain demonstrated an extra-axial fluid collection, and she was diagnosed with meningitis.  She received prolonged intravenous antibiotic therapy and aggressive treatment for lupus, leading to clinical recovery. This case illustrates the importance of recognizing GBS as a potential pathogen in all patients presenting with CNS infection .

Neisseria meningitidis endogenous endophthalmitis with meningitis in an immunocompetent child.  

Science.gov (United States)

Neisseria meningitidis is a major cause of childhood morbidity and mortality worldwide. We describe an exceptional case of an immunocompetent 15-month-old child presenting with a unilateral anterior uveitis, hypopyon, and sepsis. Anterior chamber aspirate demonstrated gram-negative cocci before Neisseria meningitidis was identified in blood and cerebrospinal fluid. Meningococcal endophthalmitis presents variably with sepsis, meningitis, or isolated ocular symptoms. Diagnosis is a clinical challenge, requiring diagnostic sampling and treatment from both pediatricians and ophthalmologists. Delayed or incorrect treatment risks blindness, disability, or death. Simultaneous invasion of meningococcus across intact blood-brain and blood-ocular barriers in this child suggests antigenic correlates between meningeal and ocular endothelial interfaces. Meningococcus is an exclusively human pathogen; research is hampered by the lack of animal models. This clinical observation suggests the potential of a novel in vitro experimental approach of using ocular tissue from eye banks to further elucidate the meningococcal-endothelial interaction that underpins meningococcal disease.

Meningeal sarcomas are very rare, highly aggressive tumours affecting children more frequently than adults. The clinical course and MRI of meningeal sarcomas in two cases are discussed with special regard to possible misinterpretation. In one case MRI demonstrated a circumscribed mass in contact with the meninges, with central areas of haemorrhage. In the other, a case of primary leptomeningeal sarcomatosis, several MRI examinations over the course of almost a year were unhelpful, despite severe neurological complaints. Then MRI revealed meningeal contrast enhancement all over the brain and spinal canal, together with cerebral infarcts. MRI of meningeal sarcomas has not been discussed in the literature. MRI did not permit specific diagnosis, but enabled visualisation of the extent of the tumour and/or meningeal involvement. Early histological diagnosis is indispensable for adequate treatment.

[First documented case of Chryseobacterium meningosepticum meningitis in Central African Republic].  

Science.gov (United States)

Chryseobacterium meningosepdcum is a rare but well-known causative agent of bacterial meningitis and can be the source of epidemic outbreak in neonatal facilities. It has rarely been documented in Africa. The purpose of this report is to describe the first case of C. meningosepticum meningitis in Central African Republic. The case that remained isolated occurred after dystocic delivery with resuscitation in a neonatal unit. Despite intensive care and appropriate antibiotic treatment, the newborn died on day 19. Identification of this rare cause of meningitis underlines the important role of the bacteriologic laboratory in managing bacterial meningitis in Africa. The strain of C. meningosepticum involved in this case was resistant to the main antibiotics used for first-intention treatment of neonatal bacterial meningitis, i.e., third-generation cefalosporins, chioramphenicol, and aminosides. This case also underlines the importance of familiarizing the medical staff with the dangers of nosocomial meningitis and reinforcing hospital hygiene measures. PMID:16775944

Tuberculous meningitis in Denmark: a review of 50 cases  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Tuberculous meningitis is the most severe manifestation of extrapulmonary tuberculosis with a high mortality rate and a high rate of sequelae among survivors. The aim of this study is to assess the current epidemiology, clinical features, diagnostic procedures, treatment and outcome in patients with tuberculous meningitis in Denmark, a country with a low tuberculosis incidence. Methods A nationwide retrospective study was conducted, comprising all patients notified with tuberculous meningitis (TBM in Denmark from 2000-2008. Medical records were reviewed using a standardised protocol. Results Fifty patients, including 12 paediatric patients, were identified. 78% of the patients were immigrants from countries of high tuberculosis endemicity. 64% of all patients had a pre-existing immunosuppressive condition; 10% were HIV positive, 48% were HIV seronegative and 42% had an unknown HIV status. Median symptom duration before admission was 14 days in the Danish patient population and 20 days in the immigrant group. Biochemical analysis of cerebrospinal fluid (CSF samples revealed pleocytosis in 90% with lymphocyte predominance in 66%. Protein levels were elevated in 86%. The most common findings on neuro-radiological imaging were basal meningeal enhancement, tuberculomas and hydrocephalus. Lumbar puncture was performed on 42 patients; 31 of these specimens (74% had a positive CSF culture for mycobacteria and 9.5% were smear positive for acid-fast bacilli. The overall mortality rate was 19% and 48% of the remaining patients had neurological sequelae of varying degree. Conclusion TBM is a rare but severe manifestation of extrapulmonary TB in Denmark. The clinician must be prepared to treat empirically if the suspicion of TBM has arisen to improve treatment outcome.

Meningeal hemangiopericytoma treated with surgery and radiation therapy -case report-  

Energy Technology Data Exchange (ETDEWEB)

Meningeal hemangiopericytoma (HPC) is an uncommon dura-based tumor and can recur not only locally but also distantly in the neural axis or extraneural sites. We report our experience of radiation therapy, one preoperative and one elective postoperative, in two patients with meningeal HPC and reviewed the role of radiation therapy. A 41-year-old man (Case 1) presented with a 3-month history of headache and right hemiparesis. The mass was nearly unresectable at the first and second operation and diagnosed as meningeal HPC. Preoperative radiation therapy was given with a total dose of 55.8 Gy/31 fractions to the large residual mass of left frontoparietal area. Follow-up computerized tomography (CT) showed marked regression of tumor after radiation therapy. The third operation was performed to remove the residual tumor at 6 months after the radiation therapy and a 2 x 2 cm sized tumor was encountered. The mass was totally removed. The serial follow-up CT showed no evidence of recurrence and he is alive without distant metastasis for 4 years and 10 months after the first operation. A 45-year-old woman (Case 2) presented with suddenly developed headache and visual impairment. Tumor mass occupying right frontal lobe was removed with the preoperative diagnosis of meningioma. It was totally removed with attached sagittal sinus and diagnosed as meningeal HPC. Elective postoperative radiation therapy was performed to reduce local recurrence with a total dose of 54 Gy/30 fractions to the involved area of right frontal lobe. She is alive for 5 years maintaining normal activity without local recurrence and distant metastasis.

Correlation of MRI and clinical features in meningeal carcinomatosis  

International Nuclear Information System (INIS)

Ten patients with meningeal carcinomatosis associated with nonhaemoatological neoplasms were examined: Six with breast, two with gastrointestinal and one with lung cancer, plus one with a tumour of unknown origin. Cytology was positive in all but one. The patients were classified into four groups according to the gadolinium-enhanced MRI (Gd-MRI) appearances: Group 1 had pure leptomeningeal carcinomatosis, group 2 dural carcinomatosis, group 3 spinal leptomeningeal carcinomatosis, and group 4 had normal Gd-MRI except for hydrocephalus. In group 1, Gd-MRI showed diffuse enhancement of the subarachnoid space, including the cisterns around the midbrain, the sylvian fissures, or cerebellar and cerebral sulci. In group 2, Gd-MRI showed diffuse, thick, partially nodular enhancement of the dura mater. No leptomeningeal or subependymal enhancement was evident. In group 3, nodular masses were seen only in the spinal canal. In group 4, no definite evidence of meningeal carcinomatosis was demonstrated on contrast-enhanced CT (CE-CT) or Gd-MRI. The median survival time was 2.0 months in group 1, 1.0 month in group 3, and 4.5 months in group 4, but the two patients in group 2 were alive 10 and 15 months after a definite diagnosis of meningeal carcinomatosis was made. In all patients examined by both CE-CT and Gd-MRI, the latter was superior for identification of meningeal carcinomatosis. Hydrocephalus is an important indirect sign of leptomeningeal carcinomatosis, but was not seen in patients with dural carcinomatosis despite the presence of increased intracranial pressure. (orig.)

Climate Drives the Meningitis Epidemics Onset in West Africa  

Directory of Open Access Journals (Sweden)

Full Text Available Background Every year West African countries within the Sahelo-Sudanian band are afflicted with major meningococcal meningitis (MCM disease outbreaks, which affect up to 200,000 people, mainly young children, in one of the world's poorest regions. The timing of the epidemic year, which starts in February and ends in late May, and the spatial distribution of disease cases throughout the "Meningitis Belt" strongly indicate a close linkage between the life cycle of the causative agent of MCM and climate variability. However, mechanisms responsible for the observed patterns are still not clearly identified. Methods and Findings By comparing the information on cases and deaths of MCM from World Health Organization weekly reports with atmospheric datasets, we quantified the relationship between the seasonal occurrence of MCM in Mali, a West African country, and large-scale atmospheric circulation. Regional atmospheric indexes based on surface wind speed show a clear link between population dynamics of the disease and climate: the onset of epidemics and the winter maximum defined by the atmospheric index share the same mean week (sixth week of the year; standard deviation, 2 wk and are highly correlated. Conclusions This study is the first that provides a clear, quantitative demonstration of the connections that exist between MCM epidemics and regional climate variability in Africa. Moreover, this statistically robust explanation of the MCM dynamics enables the development of an Early Warning Index for meningitis epidemic onset in West Africa. The development of such an index will undoubtedly help nationwide and international public health institutions and policy makers to better control MCM disease within the so-called westward-eastward pan-African Meningitis Belt.

Gene expression in cortex and hippocampus during acute pneumococcal meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Pneumococcal meningitis is associated with high mortality (~30% and morbidity. Up to 50% of survivors are affected by neurological sequelae due to a wide spectrum of brain injury mainly affecting the cortex and hippocampus. Despite this significant disease burden, the genetic program that regulates the host response leading to brain damage as a consequence of bacterial meningitis is largely unknown. We used an infant rat model of pneumococcal meningitis to assess gene expression profiles in cortex and hippocampus at 22 and 44 hours after infection and in controls at 22 h after mock-infection with saline. To analyze the biological significance of the data generated by Affymetrix DNA microarrays, a bioinformatics pipeline was used combining (i a literature-profiling algorithm to cluster genes based on the vocabulary of abstracts indexed in MEDLINE (NCBI and (ii the self-organizing map (SOM, a clustering technique based on covariance in gene expression kinetics. Results Among 598 genes differentially regulated (change factor ? 1.5; p ? 0.05, 77% were automatically assigned to one of 11 functional groups with 94% accuracy. SOM disclosed six patterns of expression kinetics. Genes associated with growth control/neuroplasticity, signal transduction, cell death/survival, cytoskeleton, and immunity were generally upregulated. In contrast, genes related to neurotransmission and lipid metabolism were transiently downregulated on the whole. The majority of the genes associated with ionic homeostasis, neurotransmission, signal transduction and lipid metabolism were differentially regulated specifically in the hippocampus. Of the cell death/survival genes found to be continuously upregulated only in hippocampus, the majority are pro-apoptotic, while those continuously upregulated only in cortex are anti-apoptotic. Conclusion Temporal and spatial analysis of gene expression in experimental pneumococcal meningitis identified potential targets for therapy.

Apart from potential roles in anti-tumor surveillance, the TNF-related apoptosis-inducing ligand (TRAIL) has important regulatory functions in the host immune response. We studied antiinflammatory effects of endogenous and recombinant TRAIL (rTRAIL) in experimental meningitis. Following intrathecal application of pneumococcal cell wall, a TLR2 ligand, we found prolonged inflammation, augmented clinical impairment, and increased apoptosis in the hippocampus of TRAIL–/– mice.

Opportunistic infections are common complications of advanced immuno-deficiency in individuals with Human Immunodeficiency Virus (HIV) infection. Following involvement of the lung, the central nervous system (CNS) is the second most commonly affected organ. We report two cases of concurrent cryptococcal meningitis and tuberculosis (TB) in HIV infected persons. A high suspicion of multiple opportunistic infections should be kept in mind in HIV seropositive individuals. PMID:24000497

Two cases of dengue meningitis: a rare first presentation.  

Science.gov (United States)

Dengue, a mosquito-borne disease caused by a flavivirus, is recognized in over 120 countries with 3.6 billion people living in areas at risk. Neurological manifestations are infrequently reported as clinical consequences of dengue infection. Though severe dengue may be associated with meningoencephalitis, meningitis is a rare initial presentation of otherwise uncomplicated dengue fever. We report two adult patients who presented with fever, headache, and nuchal rigidity without the typical symptoms of dengue infection. Cerebrospinal fluid (CSF) analysis showed lymphocytic pleocytosis in one and slight neutrophilic pleocytosis in the other with a normal glucose value and negative bacterial cultures. Dengue was suspected because thrombocytopenia was symptomatic in one patient and documented during the hospital course, and was confirmed by demonstration of IgM antibody in the cerebrospinal fluid samples specific for dengue in both cases. Our report demonstrates that meningitis with or without encephalitis can be the first manifestation of dengue infection. In endemic areas, dengue infection should be considered as a probable etiological agent of meningitis. Regular monitoring of platelet count can be an invaluable diagnostic screening tool. In appropriate clinical settings detection of anti-dengue IgM both in serum and in CSF may lead to correct diagnosis. PMID:22337854

The cribriform plate: a sanctuary site for meningeal leukaemia  

International Nuclear Information System (INIS)

Cranial irradiation is an effective prophylactic treatment for subclinical meningeal infiltration in lymphoblastic leukaemia, but, central nervous system (CNS) relapse still occurs in 6-10% of cases overall and as many as 30% of cases with a poor prognosis in some series. These recurrences may be due in part to inadvertent underdosage of the cribriform plate, centrally situated between the orbits and projected over their upper third in a lateral view. The dose to the adjacent meninges may thus be reduced by shielding of the radiosensitive lenses. This problem is exacerbated if conventional lateral fields centred on the mid-skull are used, because the eyes will not then project over one another. If the field centre is moved to the edge of the orbit, this problem of beam divergence can be overcome. Central axis beam blocking of both lenses is possible, in some patients the cribriform plate can be adequately irradiated. In most children the geometry of the orbit is such that it is necessary to add an anterior electron beam to ensure homogeneous dosage. These refinements in technique might prevent meningeal relapse with a lower whole-brain dose and, hence, fewer neurophyschological sequelae. (author)

Progress towards meningitis prevention in the conjugate vaccines era  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english Acute bacterial meningitis is an important cause of morbidity and mortality among children less than five years old. Haemophilus influenzae, Streptococcus pneumoniae and Neisseria meningitidis are the most important agents of bacterial meningitis in developing countries. The development of the conju [...] gate vaccines in the beginning of the 90's, especially type b H. influenzae (Hib), and more recently the heptavalent pneumococcal and the serogroup C meningococcal vaccines, have contributed directly to changes in the epidemiological profile of these invasive diseases (direct effect) and of their carriage status (indirect effect). We review the impact of the Hib conjugate vaccine in Latin American countries, where this vaccine has been implemented, and the potential of pneumococcal and meningococcal conjugate vaccines for the reduction of meningitis worldwide. We also address constraints for the development and delivery of these vaccines and review new candidate state-of-the-art vaccines. The greatest challenge, undoubtedly, is to implement these vaccines worldwide, especially in the developing regions.

Cat scratch disease complicated with aseptic meningitis and neuroretinitis  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english Cat scratch disease (CSD) is a self limited condition characterized by fever, lymph node enlargement and less often eye involvement. Central nervous system involvement by Bartonella henselae infection is possibly an important cause of morbidity; its role as an agent of aseptic meningitis is unknown. [...] We report a case of a 40 years-old man with CSD accompanied by aseptic meningitis and neuroretinitis. Serum indirect immmunofluorescence (IFI) assays for B. henselae were positive and the cerebrospinal fluid (CSF) analysis showed mononuclear pleocytosis and increased level of protein. Serological tests for other etiologies were negative. The patient responded well to antibiotic therapy with oral doxycicline plus rifampin and in the 12th day of hospitalization evolved to total regression of the headache and partial regression of the visual loss. Clinicians should consider CSD as a differential diagnosis when assessing previously healthy patients with aseptic meningitis associated with regional lymphadenopathy and epidemiological history of feline contact.

Spontaneous pneumorrhachis and transverse myelitis complicating purulent meningitis.  

Science.gov (United States)

Pneumorrhachis is the presence of air in the spinal canal; mostly, it has an iatrogenic origin. The association of this entity with spontaneous pneumomediastinum without any pneumothorax is rarely reported in the literature. The spontaneous resorption is the usual evolution. The association to acute transverse myelitis is discussed by the authors. The patient is a 21-year-old male with pneumorrhachis associated to a spontaneous pneumomediastinum was admitted at the emergency department for bacterial meningitis. The antibiotherapy has marked the clinical profile by disappearance of the meningeal signs in the 48 h after admission. In contrast, the neurological symptoms were of marked aggravation by appearance of a tetraparesis with a respiratory distress syndrome having required artificial ventilation. The computed tomography (CT) scan showed a typical hypodensity corresponding to paramedullary air extending to several thoracic segments. The spinal magnetic resonance imaging (MRI) showed a high cervical medullary edema without signs of compression. The patient died within 15 days with a profile of vasoparalysis resistant to vasoactive drugs. Pneumomediastinum associated to pneumorrhachis and transverse myelitis complicating purulent meningitis is a rare entity. Although the usual evolution is favorable, the occurrence of serious complications is possible. PMID:24672182

[Cryptococcal meningitis in children: description of 3 cases].  

Science.gov (United States)

Cryptococcal meningitis is much less common in children than adults. The purpose of this report is to describe 3 cases of cryptococcal meningitis observed in children admitted to the Neurology Department of the Fann University Hospital Center in Dakar, Senegal between July 2003 and November 2008. There were 2 girls whose ages were 8 and 15 years and one 9-year-old boy. All 3 patients presented acute or chronic meningoencephalitis. Diagnosis was based on direct microscopic examination of India ink preparations of cerebrospinal fluid (CSF) showing Cryptococcus neoformans at direct exam. Two patients were immunocompromised including one presenting severe protein-caloric malnutrition and one infected by HIV-1. The third patient was immunocompetent. All 3 patients were treated by intravenous Fluconazole. The immunocompetent boy died after 1 month of hospitalization due to cardiovascular and respiratory insufficiency. Both girls survived with severe neurosensory sequels. Cryptococcal meningitis that is relatively frequent in adulthood may be underestimated in children and should be tested for in any children presenting meningoencephalitis of undetermined cause.

Enterococcal meningitis caused by Enterococcus casseliflavus. First case report  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Enterococcal meningitis is an uncommon disease usually caused by Enterococcus faecalis and Enterococcus faecium and is associated with a high mortality rate. Enterococcus casseliflavus has been implicated in a wide variety of infections in humans, but never in meningitis. Case presentation A 77-year-old Italian female presented for evaluation of fever, stupor, diarrhea and vomiting of 3 days duration. There was no history of head injury nor of previous surgical procedures. She had been suffering from rheumatoid arthritis for 30 years, for which she was being treated with steroids and methotrexate. On admission, she was febrile, alert but not oriented to time and place. Her neck was stiff, and she had a positive Kernig's sign. The patient's cerebrospinal fluid was opalescent with a glucose concentration of 14 mg/dl, a protein level of 472 mg/dl, and a white cell count of 200/?L with 95% polymorphonuclear leukocytes and 5% lymphocytes. Gram staining of CSF revealed no organisms, culture yielded E. casseliflavus. The patient was successfully treated with meropenem and ampicillin-sulbactam. Conclusions E. casseliflavus can be inserted among the etiologic agents of meningitis. Awareness of infection of central nervous system with Enterococcus species that possess an intrinsic vancomycin resistance should be increased.

Carcinomatous meningitis appearing as acoustic neuromas. Two cases  

Energy Technology Data Exchange (ETDEWEB)

Background: For acoustic neuromas, stereotactic radiotherapy (radiosurgery or stereotactic fractionated radiotherapy) has been established as an important alternative to microsurgery. In most cases initial symptoms are slow progression of unilateral hearing loss, tinnitus or vertigo or acute hearing loss with vertigo. MRI scan shows a contrast-enhancing tumor within the inner auditory channel. If the patient undergoes primary radiotherapy, diagnosis is usually not verified histologically. Therefore, careful evaluation of the medical history is mandatory despite a typical appearance on the MRI scan. If medical history does not match with acoustic neuroma, further diagnostics are necessary to rule out infectious disease or carcinomatous meningitis. Case Report: Two patients with hearing loss, vertigo and the diagnosis of acoustic neuromas by MRI scan were referred for radiotherapy. In both cases the symptoms progressed very rapidly, not typical of acoustic neuromas, and in both patients repeated liquor puncture finally revealed carcinomatous meningitis. One patient died during therapy; in the second patient intrathecal chemotherapy and additional radiotherapy of the skull base led to partial remission continuing for several months. Conclusion: Before primary radiotherapy of small intrameatal lesions diagnosis must be reassessed carefully. This is especially true for bilateral lesions suspicious for acoustic neuromas and rapid progression and persistence of clinical symptoms where carcinomatous meningitis has to be taken into account.

Antibiotic Therapy in Pyogenic Meningitis in Paediatric Patients  

International Nuclear Information System (INIS)

Objective: To isolate and identify the causative pathogen, antibiotic sensitivity testing and success rate of empirical antibiotic therapy in pyogenic meningitis. Study Design: Analytical study. Place and Duration of Study: The Children's Hospital and Institute of Child Health, Lahore, Pakistan, from March to July 2012. Methodology: The study was performed on 72 culture positive meningitis cases in children less than 15 years of age. This therapy was evaluated by monitoring the patient's clinical picture for 14 - 21 days. The collected data was analyzed by Chi-square test. Results: Seventeen different bacteria were isolated. The most commonly occurring bacteria were coagulase negative Staphylococci (25%), E. coli (12.5%), Klebsiella pneumoniae (8.3%), Streptococcus pneumoniae (8.3%) and Pseudomonas aeruginosa (8.3%). All the bacteria were sensitive to vancomycin (96.7%), meropenem (76.7%), amikacin (75%), ciprofloxacin (65.3%), chloramphenicol (46.5%), ceftazidime (44.2%), cefepime (41.9%), co-amoxiclav (38.0%), oxacillin (34.8%), cefotaxime (21.4%), penicillin (20.7%), ceftriaxone (18.6%), cefuroxime (14%) and ampicillin (6.9%). The combination of sulbactam and cefoperazone showed antimicrobial sensitivity of 81.4%. The success rate of empirical antibiotic therapy was 91.7%. Conclusion: It was found that Gram negative bacteria were the major cause of pyogenic meningitis. Mostly there were resistant strains against all commonly used antibiotics except vancomycin.

Spinal meningeal melanocytoma with benign histology showing leptomeningeal spread: Case report  

International Nuclear Information System (INIS)

Meningeal melanocytoma is a rare benign tumor with relatively good prognosis. However, local aggressive behavior of meningeal melanocytoma has been reported, especially in cases of incomplete surgical resection. Malignant transformation was raised as possible cause by prior reports to explain this phenomenon. We present an unusual case of meningeal melanocytoma associated with histologically benign leptomeningeal spread and its subsequent aggressive clinical course, and describe its radiological findings.

Predictive Value of Decoy Receptor 3 in Postoperative Nosocomial Bacterial Meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available Nosocomial bacterial meningitis requires timely treatment, but what is difficult is the prompt and accurate diagnosis of this disease. The aim of this study was to assess the potential role of decoy receptor 3 (DcR3 levels in the differentiation of bacterial meningitis from non-bacterial meningitis. A total of 123 patients were recruited in this study, among them 80 patients being with bacterial meningitis and 43 patients with non-bacterial meningitis. Bacterial meningitis was confirmed by bacterial culture of cerebrospinal fluid (CSF culture and enzyme-linked immunosorbent assay (ELISA was used to detect the level of DcR3 in CSF. CSF levels of DcR3 were statistically significant between patients with bacterial meningitis and those with non-bacterial meningitis (p < 0.001. A total of 48.75% of patients with bacterial meningitis received antibiotic >24 h before CSF sampling, which was much higher than that of non-bacterial meningitis. CSF leucocyte count yielded the highest diagnostic value, with an area under the receiver operating characteristic curve (ROC of 0.928, followed by DcR3. At a critical value of 0.201 ng/mL for DcR3, the sensitivity and specificity were 78.75% and 81.40% respectively. DcR3 in CSF may be a valuable predictor for differentiating patients with bacterial meningitis from those with non-bacterial meningitis. Further studies are needed for the validation of this study.

Cytokine-induced meningitis is dramatically attenuated in mice deficient in endothelial selectins.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Leukocyte accumulation in cerebrospinal fluid and disruption of the blood-brain barrier are central components of meningitis and are associated with a poor prognosis. Genetically engineered deficiencies or functional inhibition of endothelial leukocyte adhesion receptors P-, or P- plus E-selectins, lead to deficits in leukocyte rolling and extravasation. However, their impact on meningeal inflammation has not been tested previously. An acute cytokine-induced meningitis model associated with s...

The contribution of MRI to the diagnosis of diffuse meningeal lesions  

International Nuclear Information System (INIS)

We analysed MRI findings in patients in whom a diffuse abnormality of the meninges was revealed by MRI. We looked at T1 and T2-weighted spin-echo or fast spin-echo images and contrast-enhanced T1-weighted images. There were 15 patients with abnormalities on MRI, clinically suspected in ten. Four had meningoencephalitis, one meningeal and subcortical sarcoidosis nodules, four meningeal malignancies - one disseminated oligodendroglioma, one with meningeal infiltration around an adenocarcinoma, three meningeal infiltration by a haematological malignancy, and one a chronic subdural haematoma without a history of injury. We excluded patients with primary meningeal tumours and typical injury-related meningeal bleeding. The relatively small number of patients is due to both the infrequency of diffuse meningeal disease and to the low frequency of suspected meningeal pathology as an indication for MRI. The latter's diagnostic contribution is greatest in infectious disease and neoplastic infiltration, and less obvious in haematological malignancies. Contrast-enhanced T1-weighted images are most useful. (orig.)

Meningeal carcinomatosis as the initial manifestation of a gallbladder adenocarcinoma associated with a Krukenberg tumor  

Directory of Open Access Journals (Sweden)

Full Text Available A case of malignant neoplasm is described in which the initial manifestations were mental dysfunction and meningeal irritation, mimicking chronic or subacute meningitis. Physical examination showed cranial nerve involvement and a pelvic tumor. There was progressive deterioration, and death occurred in 2 weeks. The autopsy revealed a gallbladder adenocarcinoma, meningeal carcinomatosis, and ovarian metastasis presenting as a Krukenberg tumor. The authors emphasize the importance of including meningeal carcinomatosis as a possibility in the differential diagnosis of non-characteristic clinical pictures, as well as the importance of the cerebrospinal fluid cytologic examination, repeated as needed, in order to confirm this diagnosis.

The cerebrospinal fluid cytological features of tuberculous meningitis in children  

Directory of Open Access Journals (Sweden)

Full Text Available Background Tuberculous meningitis (TBM is a common central nervous system (CNS infectious disease, and is a serious threat to people's health. Due to its diverse clinical manifestations, especially atypical in infants and young children, it is easy to be misdiagnosed and can lead to high disablility rate and mortality rate. At present, cerebrospinal fluid (CSF cytology still plays an important role in the etiological diagnosis of CNS infectious diseases. Based on the observation of CSF cytological changes of children with TBM, this study is to further understand the performance and evolution characteristics of this disease, so as to improve the ability of early diagnosis and judgment on the treatment effect. Methods Fresh CSF was collected to make smears by using cytological slide centrifugation, and apply May-Grunwald-Giemsa (MGG staining for morphological classification. Results CSF cytology of all patients were abnormal. The average leukocyte count of children with TBM was (310.19 ± 156.26× 106/L, and was significantly different from that of children with purulent meningitis (P = 0.000. Lymphocyte proportion of TBM group was (66.56 ± 14.08%, and there were significant differences among different groups ( P = 0.037, 0.000. Compared to children with purulent meningitis, higher proportion of monocytes ( P = 0.000, 0.020 and plasma cells ( P = 0.001, 0.004 were found in children with TBM and viral meningitis. The positive detection rate of plasma cells in children with TBM was higher than that in children with purulent meningitis ( P = 0.001. Conclusion The CSF cytology changing characteristics of children with TBM are revealed. In the beginning the lymphocyte proportion is dominant in CSF cytology, and then different extents of mixed cellular response appear as disease develops. For children with effective treatment, the proportion of neutrophils decreases rapidly and turns to lymphocyte reaction gradually, with monocytes and plasma cells, lasting for a long time. Long-term mixed cellular response will happen in children with ineffective treatment. All in all, the CSF cytology changing characteristics are significant in clinical diagnosis and differential diagnosis of TBM in children.

Meningeal fibrosarcoma: a case report and review of the literature.  

Science.gov (United States)

Meningeal Fibrosarcoma (MF) accounts only for 0.5% of the brain tumors. Since the clinical manifestations and radiologic findings are non-specific, the diagnosis can only be achieved by pathological examination of surgically removed specimens. MF are tumors that behave locally very aggressively and respond poorly to treatment, with reported median survivals ranging from 6 to 15 months. We report a new case of MF describing the peculiar onset as a slow growing mass in scalp with bone destruction and without neurological clinical findings. PMID:1546523

Erysipelothrix rhusiopathiae is a gram-positive bacillus which is found worldwide. Although bloodstream infections caused by E. rhusiopathiae are not common, there is a strong association between bacteremia and the development of infective endocarditis. The risk of human infection with Erysipelothrix is closely related to the opportunity for exposure to the organisms. We report a case of community-acquired meningitis as an initial manifestation of E. rhusiopathiae endocarditis in a 56-year-old woman, who had no history of exposure to animals. PMID:21409531

Experiences of diagnosis and treatment of 102 cases with cryptococcal meningitis and/or cryptococcal meningoencephalitis  

Directory of Open Access Journals (Sweden)

Full Text Available Objective To summarize the clinical manifestations and diagnostic and therapeutic strategies of 102 cases with cryptococcal meningitis and/or cryptococcal meningoencephalitis, and to improve the diagnosis and treatment of cryptococcal meningitis.  Methods The clinical manifestations, diagnostic and therapeutic strategies and outcomes of 102 cases with cryptococcal meningitis and/or cryptococcal meningoencephalitis were analyzed retrospectively.  Results The incidence of cryptococcal meningitis and/or cryptococcal meningoencephalitis raised in recent years. The signs of high intracranial pressure, meningeal irritation and cranial nerves impairment are the main clinical manifestations of cryptococcal meningitis, while seizures, hemiplegia, mental disorders and ataxia can occur when the brain parenchyma is involved. Cryptococcal meningitis and/or cryptococcal meningoencephalitis is easy to be misdiagnosed, especially misdiagnosed as tuberculous meningitis. Repeated cerebrospinal fluid (CSF smear and latex agglutination test can ensure the diagnostic accuracy. Amphotericin B, flucytosine and fluconazole combined therapy is the most widely used therapeutic strategy at present, which has been proved to be effective; surgery operations (such as ventriculo-peritoneal shunt are effective in the treatment of cryptococcal meningitis complicating hydrocephalus.  Conclusions The diagnosis of cryptococcal meningitis and/or cryptococcal meningoencephalitis is difficult for its lack of specific clinical manifestations. Suspected patients should receive repeated CSF smear, latex agglutination test as well as imageological examination to make an accurate diagnosis. Combined, long-term antifungal therapy should be used immediately in confirmed cases, and surgery operations can be used in necessity to improve outcomes. doi: 10.3969/j.issn.1672-6731.2014.08.008

[Methicillin resistant Staphylococcus aureus community acquired meningitis: a case report].  

Science.gov (United States)

Community-acquired Staphylococcus aureus (CA-SA) infections are becoming more frequent. Most cases present an infection of skin and soft tissue, and the most invasive forms observed are osteoarticular and pleuropulmonary infections. Meningitis is a rare manifestation of Sthapylococcus aureus infections. We describe an unusual case of CA-MRSA infection. An infant of eight months presented with signs of irritability and 4 days duration fever, with alternating sensory and abdomen pain. Acute abdomen surgery was discarded and hospitalization was decided with diagnosis of sepsis due to probable enteral focus; antibiotics were indicated. Blood cultures and cerebrospinal fluid culture were positive for MRSA. Sepsis with meningitis by MRSA was diagnosed. On the 7th day of hospitalization the infant presented neurological signs and symptoms. On the resolution computed tomography and the magnetic resonance, images compatible with myelitis were observed. The patient complied with the 21 day endovenous treatment, and showed positive results, being discharged from hospital a month after the appearance of the symptoms. PMID:25362926

Neurologic deterioration in a child undergoing treatment for tuberculosis meningitis.  

Science.gov (United States)

Clinical deterioration while receiving antituberculosis (anti-TB) therapy can be due to a number of etiologies, including drug resistance, disease progression despite effective therapy, or alternative diagnoses. We present the case of a 22-month-old girl diagnosed with TB meningitis 4 months prior to presentation. At time of her initial diagnosis, computed tomography showed hydrocephalus and basilar meningitis with some evidence of ischemic damage. She required placement of a ventriculoperitoneal shunt and was discharged on multidrug anti-TB therapy and corticosteroids. At the time of her second emergency department presentation, she had developed new-onset seizures and hemiparesis. Her steroids had been tapered and discontinued. Differential diagnosis included shunt malfunction and/or shunt infection. Magnetic resonance imaging of the brain showed interval development of tuberculomas. Symptomatic and radiographic improvement was seen after initiation of corticosteroids for immune reconstitution inflammatory syndrome, which can be seen in immunocompetent children, with onset weeks to months after starting antituberculous therapy.

Priority during a meningitis epidemic: vaccination or treatment?  

Science.gov (United States)

From November 1995 to May 1996, a meningitis epidemic occurred in northern Nigeria. More than 75,000 cases and 8440 deaths (case fatality rate (CFR), 11%) were recorded. Médecins sans Frontières, in cooperation with the Nigerian government, carried out an assistance programme (support to case management, surveillance and mass vaccination) in three states (Bauchi, Kano, Katsina) where 75% of cases occurred. Cost analysis of this assistance in Katsina State reveals that case management and mass vaccination were efficient: US$ 35 per case treated and US$ 0.64 per vaccination. There was, however, a remarkable difference in cost-effectiveness between the two strategies. The cost per death averted by improved case treatment was estimated to be US$ 396, while the cost per death averted by vaccination was estimated to be US$ 6000. In large part this difference is attributed to the late start of vaccination: more than 6 weeks after the epidemic threshold had been passed. During meningitis epidemics in countries where surveillance systems are inadequate, such as in most of sub-Saharan Africa, curative programmes should have priority. PMID:9648353

Meningococcal Meningitis: Monitoring the Use of Appropriate Antibiotic Prophylaxis  

Directory of Open Access Journals (Sweden)

Full Text Available Aim: The aim of this study was to evaluate the use of recommended antibiotic prophylaxis in reported cases of meningococcal meningitis. Method: All cases of meningococcal meningitis reported to the public health authority of the Puy-de- Dôme (Direction départementale des affaires sanitaires et sociales during 1999 and 2000 were studied. Each report included the date of infection and the number of individuals exposed. This information was compared to data on rifampicin prescriptions during the same period obtained from the specific drug-codes contained in French national health insurance’s computer database. Results: We selected those treatments which were likely to represent prophylactic rifampicin use and, by using a correction coefficient, identified a theoretic number of prophylactic prescriptions. This number was considered to be the high threshold for prophylactic prescriptions. Using these two indicators, we quantified the disparity between recommendations and the actual implementation of appropriate antibiotic prophylaxis. Finally, we propose an efficiency indicator by determining how soon after exposure prophylactic rifampicin was prescribed. Conclusion: The specific drug-codes can provide us with indicators for quantifying the implementation of appropriate antibiotic prophylaxis.

Meningitis y artritis por Haemophilus influenzae en un adulto  

Directory of Open Access Journals (Sweden)

Full Text Available Tradicionalmente el Haemophilus influenzae ha sido considerado un germen causante de infecciones en niños; en adultos se lo ha relacionado con Infecciones respiratorias, pero en los últimos tiempos se han descrito en ellos infecciones severas cuando hay algunos factores predisponentes. Se describe un paciente drogadicto de 30 años con cuadro de meningitis y artritis y prueba de látex y cultivo de LCR positivos para HaemophiIus influenzae, quien recibió tratamiento con ampicilina, 2 gramos Intravenosos cada 4 horas y evolucionó a la mejoría sin secuelas. Se plantea la necesidad de tener en cuenta al Haemophilus influenzae como patógeno del adulto y más en aquellas personas con factores predisponentes.

Haemophilus influenzae has traditionally been considered as an infectious agent that predominantly affects children; instead, in adults It has been Linked either to respiratory infections or to gevere infections occurring when predisposing factors are present. We describe a 30 year-old drug adict patient that presented with meningitis and arthritis; both latex test and cerebrospinal fluid culture were positive for Haemophilus influenzae. He was treated with ampicilin 2 gm, I. V. every four hours and improved without sequelae. This microorganism must be considered among those affecting adult patients specially when predisposing factors for infection are present.

Meningitis due to Enterobacter aerogenes subsequent to resection of an acoustic neuroma and abdominal fat graft to the mastoid  

Directory of Open Access Journals (Sweden)

Full Text Available Meningitis is an uncommon complication of neurosurgical procedures, with an incidence of 1.1% to 2.5%. Although unusual, the frequency of nosocomial Gram-negative meningitis appears to be increasing. Gram-negative meningitis has been documented following disruption of the dura-arachnoid barrier secondary to trauma or surgery. The association of Gram-negative bacillary meningitis with neurosurgical procedures was first reported in the 1940's. Wolff et al. described the association between Enterobacter species and post-neurosurgical infection. More recently, risk factors for nosocomial Enterobacter meningitis have been characterized by Parodi et al. Adipose graft, as an independent risk factor has not yet been reported. A patient with acoustic neuroma resection, who developed bacterial meningitis from an abdominal fat pad graft to a mastoidectomy bed is described. A brief overview was made of post-neurosurgical Gram-negative meningitis.

Meningeal hemangiopericytoma only diagnosed at the time of late bone metastasis.  

Science.gov (United States)

Hemangiopericytoma is a rare neoplasm. Primary meningeal hemangiopericytomas account for 1 to 7 % of all meningeal tumors. In the literature, meningeal hemangiopericytomas are mainly case reports, which confirm an aggressive behavior with a high rate of local recurrence and extracranial metastasis. Metastasis can be seen many years after initial surgical excision of the primary tumor, and the most common sites include the bone, liver and lung. We present a pathological study of four meningeal hemangiopericytomas with bone metastases. All patients are male with a mean age of 46.5 years. Metastases only involved bone. Three out of four lesions were initially misdiagnosed as meningiomas. Only one case was initially correctly diagnosed as meningeal hemangiopericytoma. All patients underwent surgery with complete resection. Only the patient immediately diagnosed with meningeal hemangiopericytoma received postoperative radiation therapy. Three patients had bone metastases without local recurrence including the one who received radiation therapy. One patient recurred locally after 7 years, and bone metastasis was found at the same time. Our cases confirm that meningeal hemangiopericytomas are a separate entity and have a high recurrence rate despite complete surgical resection, with extracranial metastases, mainly to bone, even after long intervals.

Arthritis in adults with community-acquired bacterial meningitis: a prospective cohort study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Although the coexistence of bacterial meningitis and arthritis has been noted in several studies, it remains unclear how often both conditions occur simultaneously. Methods We evaluated the presence of arthritis in a prospective nationwide cohort of 696 episodes of community-acquired bacterial meningitis, confirmed by culture of cerebrospinal fluid, which occurred in patients aged >16 years. The diagnosis of arthritis was based upon the judgment of the treating physician. To identify differences between groups Fisher exact statistics and the Mann-Whitney U test were used. Results Arthritis was recorded in 48 of 696 (7% episodes of community-acquired bacterial meningitis in adults. Joint-fluid aspirations were performed in 23 of 48 patients (48% and joint-fluid cultures yielded bacteria in 6 of 23 patients (26%. Arthritis occurred most frequently in patients with meningococcal meningitis (12%. Of the 48 patients with bacterial meningitis and coexisting arthritis, four died (8% and 10 (23% had residual joint symptoms. Conclusion Arthritis is a common manifestation in patients with community-acquired bacterial meningitis. Functional outcome of arthritis in bacterial meningitis is generally good because meningococcal arthritis is usually immune-mediated, and pneumococcal arthritis is generally less deforming than staphylococcal arthritis. Nevertheless, additional therapeutic measures should be considered if clinical course is complicated by arthritis. In patients with infectious arthritis prolonged antibiotic therapy is mandatory.

Long-term effects from bacterial meningitis in childhood and adolescence on postural control.  

Science.gov (United States)

Bacterial meningitis in childhood is associated with cognitive deficiencies, sensorimotor impairments and motor dysfunction later in life. However, the long-term effects on postural control is largely unknown, e.g., whether meningitis subjects as adults fully can utilize visual information and adaptation to enhance stability. Thirty-six subjects (20 women, mean age 19.3 years) treated in childhood or adolescence for bacterial meningitis, and 25 controls (13 women, mean age 25.1 years) performed posturography with eyes open and closed under unperturbed and perturbed standing. The meningitis subjects were screened for subjective vertigo symptoms using a questionnaire, clinically tested with headshake and head thrust test, as well as their hearing was evaluated. Meningitis subjects were significantly more unstable than controls during unperturbed (p?0.014) and perturbed standing, though while perturbed only with eyes open in anteroposterior direction (p?=?0.034) whereas in lateral direction both with eyes open and closed (p<0.001). Meningitis subjects had poorer adaption ability to balance perturbations especially with eyes open, and they frequently reported symptoms of unsteadiness (88% of the subjects) and dizziness (81%), which was found significantly correlated to objectively decreased stability. Out of the 36 subjects only 3 had unilateral hearing impairment. Hence, survivors of childhood bacterial meningitis may suffer long-term disorders affecting postural control, and would greatly benefit if these common late effects became generally known so treatments can be developed and applied.

KARIER MENINGITIS MENINGOKOK PADA JEMAAH HAJI INDONESIA TAHUN 1993-2003  

Directory of Open Access Journals (Sweden)

Full Text Available Research and routine survey of meningococcal meningitis on Indonesian hajj pilgrims have been conducted since 1993 until now. This paper consists of several research and routine survey of meningococcal meningitis during 1993 and 2003. The objectives of the test were determining the meningococcal meningitis carrier on hajj pilgrims, determining the serogroup of N. meningitidis and knowing sensitivity of bacteria to several antibiotics. The result showed increasing of meningococcal meningitis carrier in 1993 up to 1996, that was 1.3% - 9,4% respectively. This proportion of meningococcal meningitis carrier in the case groups decreased after given of rifampicin in 1994 and cyprofloxacin in 1997 as a chemoprophilactic. The result of the study in 1997 indiciated that the carrier rate of groups with cyprofloxacin (1.4% was lower than rifampicin group (1.4%. Most of the isolated bacteria of N. meningitidis in 1996 and 1997 were resistant to rifampicin (sensitivity test was 0-33%. Serogroup B of N. meningitidis were found dominantly between 1993 and 1999, it changed to be serogroup W135 from 2000 to 2003. The changes related  with the majority cases of meningococcal meningitis in another countries that caused by serogroup W135. Because  of  that  since 2002, immunization program has given a tetravalen (serogroup ACYW135 meningococcal vaccine to all of Indonesian hajj pilgrims. The carrier of meningococcal meningitis is still found in hajj pilgrims and their contact. More attention must be given, caused of meningococcal meningitis serogroup B vaccine is not available. The further researches are needed especially for subtype of N. meningitidis, effectivity of the drug choice and development of meningococcal meningitis vaccine serogroup B.

Prediction of bacterial meningitis based on cerebrospinal fluid pleocytosis in children  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english Children with cerebrospinal fluid pleocytosis are frequently treated with parenteral antibiotics, but only a few have bacterial meningitis. Although some clinical prediction rules, such as bacterial meningitis score, are of well-known value, the cerebrospinal fluid white blood cells count can be the [...] initial available information. Our aim was to establish a cutoff point of cerebrospinal fluid white blood cell count that could distinguish bacterial from viral and aseptic meningitis. A retrospective study of children aged 29 days to 17 years who were admitted between January 1st and December 31th, 2009, with cerebrospinal fluid pleocytosis (white blood cell > 7 µL-1) was conducted. The cases of traumatic lumbar puncture and of antibiotic treatment before lumbar puncture were excluded. There were 295 patients with cerebrospinal fluid pleocytosis, 60.3% females, medium age 5.0 ± 4.3 years distributed as: 12.2% 1-3 months; 10.5% 3-12 months; 29.8% 12 months to 5 years; 47.5% >5 years. Thirty one children (10.5%) were diagnosed with bacterial meningitis, 156 (52.9%) viral meningitis and 108 (36.6%) aseptic meningitis. Bacterial meningitis was caused by Neisseria meningi tidis (48.4%), Streptococcus pneumoniae (32.3%), other Streptococcus species (9.7%), and other agents (9.7%). cerebrospinal fluid white blood cell count was significantly higher in patients with bacterial meningitis (mean, 4839 cells/µL) compared to patients with aseptic meningitis (mean, 159 cells/µL, p

Handheld point-of-care cerebrospinal fluid lactate testing predicts bacterial meningitis in Uganda.  

Science.gov (United States)

We validated a handheld point-of-care lactate (POCL) monitor's ability to measure lactate in cerebrospinal fluid (CSF) and diagnose bacterial meningitis in Uganda. There was a strong linear correspondence between POCL and standard laboratory lactate test results (R(2) = 0.86; P POCL was 0.92 (95% confidence interval = 0.85-0.99, P POCL concentration of 7.7 mmol/L provided 88% sensitivity and 90% specificity for the diagnosis of bacterial meningitis. CSF POCL testing had excellent use in the diagnosis of bacterial meningitis, and it may be useful where CSF analyses are delayed or laboratory infrastructure is limited. PMID:23243109

Chronic bilateral hearing loss in an immunocompetent patient. An atypical course of tuberculous meningitis.  

Science.gov (United States)

Congenital, infectious, toxic, and demyelinating disorders are common etiological causes of deafness. Tuberculous meningitis, as one of the infectious causes, should be considered in the differential diagnosis since tuberculosis represents an endemic public health problem in developing countries. Multiple cranial nerve palsies can be expected due to basal meningitis; however, presentation with bilateral hearing loss is quite rare. Early diagnosis and treatment are crucial to prevent mortality and residual neurologic deficits. The focus of this discussion is a 42-year-old female presenting with bilateral hearing loss and nonspecific complaints who was finally diagnosed with chronic tuberculous meningitis. We also demonstrate the characteristic radiological and histopathological findings. PMID:25274594

Full Text Available Rhodotorula spp . are common saprophytes but may be responsible for systemic infections in immunocompromised patients. Meningitis caused by Rhodotorula spp. in human immunodeficiency virus (HIV infected patients has been reported only rarely. We present a case of meningitis caused by Rhodotorula rubra in HIV infected patient. The presumptive diagnosis of cryptococcal meningitis was made on the basis of India ink preparation, Gram staining and latex agglutination test (LAT for cryptococcal antigen. The final diagnosis was confirmed by isolation of Rhodotorula rubra from cerebrospinal fluid on culture. LAT was considered false positive. Amphotericin B and 5-fluorocytosine were administered but the patient succumbed to his illness.

Unusual exanthema combined with cerebral vasculitis in pneumococcal meningitis: a case report  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Introduction Bacterial meningitis is a complex, rapidly progressive disease in which neurological injury is caused in part by the causative organism and in part by the host's own inflammatory responses. Case presentation We present the case of a two-year-old Greek girl with pneumococcal meningitis and an atypical curvilinear-like skin eruption, chronologically associated with cerebral vasculitis. A diffusion-weighted MRI scan showed lesions with restricted diffusion, reflecting local areas of immunologically mediated necrotizing vasculitis. Conclusions Atypical presentations of bacterial meningitis may occur, and they can be accompanied by serious unexpected complications.

El objetivo [...] del presente trabajo es determinar la validez y seguridad de una escala clínica predictiva para el diagnóstico de meningitis bacteriana en Pediatría. Métodos: Realizamos un estudio retrospectivo, transversal, de evaluación de una prueba diagnóstica en una muestra de pacientes con edades entre 29 días y 12 años, egresados con diagnóstico de meningitis entre enero de 1992 y diciembre de 2006, del Departamento de Pediatría del Hospital “Dr. Jesús Yerena”, ubicado en Caracas, Venezuela. Aplicamos una escala clínica predictiva y calculamos su sensibilidad, especificidad, valores predictivos y razones de verosimilitud para el diagnóstico de meningitis bacteriana. Resultados: La muestra estuvo conformada por 41 pacientes. Predominó el sexo masculino (n=29; 70,73 %). El grupo etareo más afectado fue el de los lactantes menores (n=26; 63,41 %). Se identificaron 14 meningitis bacterianas y 27 asépticas. Mediante la escala clínica predictiva se clasificaron 31 meningitis como de alto riesgo de meningitis bacteriana y 10 como de bajo riesgo. La sensibilidad y valor predictivo negativo fueron de 100 %. Conclusiones: La escala clínica predictiva aplicada resultó ser válida y segura para descartar meningitis bacteriana. Abstract in english Introduction: The overlapping of findings suggestive of bacterial or viral meningitis in cerebrospinal fluid makes it difficult to differentiate one of another. For decades, investigators have attempted to create clinical prediction scores to resolve such disjunctive. The objective of this investiga [...] tion was to determine the validity and safety of a clinical prediction score for the diagnosis of bacterial meningitis in childhood. Methods: We performed a retrospective, transversal, diagnostic test evaluation study of a sample of patients between 29 days to 12 years of age, discharged from January 1992 to December 2006, with diagnosis of meningitis, from the Pediatrics Department of Dr. Jesús Yerena Hospital, in Caracas, Venezuela. The clinical prediction score was applied. We evaluated its validity and safety with the calculation of sensibility, specificity, predictive values and likelihood ratios for the diagnosis of bacterial meningitis. Results: A total of 41 patients were included. Male gender was more common (n= 29; 70,73 %). The infant age group was predominant (n=26 ; 63,41 %). We identified 14 bacterial meningitis and 27 aseptic meningitis. With the clinical prediction score, 31 meningitis were classified as high risk of bacterial meningitis and 10 as low risk. The sensibility and the negative predictive value were 100 %. Conclusions: The clinical prediction score applied resulted to be valid and safe for identifying patients without bacterial meningitis.

[Acute disseminated encephalomyelitis (ADEM) onset during meningitis and sepsis].  

Science.gov (United States)

A 39-year-old man with a high fever, headache, and stiff neck, and Kernig and Brudzinski signs admitted in June 2004 had a WBC of 10,680/microL and CRP of 10.5mg/dL. Streptococcus pneumoniae was detected in blood and spinal fluid culture, but brain CT was normal. Meningitis was diagnosed and antibiotics and corticosteroids begun. After four days of treatment, his blood test and spinal fluid data had improved, but his consciousness had deteriorated. ADEM was diagnosed by the clinical course and brain MRI (T2-weighted image) that showed high-intensity lesions in the white cerebral matter, and steroid pulse treatment was begun on day 4 after admission. His consciousness disturbance rapidly disappeared and brain MRI showed that the multiple high-intensity lesions had ameliorated. The patient was released after 40 days of treatment. PMID:17966640

Intracranial meningeal masson's hemangioma: CT and angiographic features  

International Nuclear Information System (INIS)

Masson's hemangioma is a rare benign vascular condition with a papillary intravascular endothelial proliferation which may appear either as a primary form as a secondary form in a pre-existing vascular process. CT and angiographic features of 2 cases with Masson's hemangioma were presented. Both of them were located extra-axially in the posterior fossa. CT findings were not specific in both cases; One showed homogeneously enhancing mass, simulating meningioma. And the other demonstrated a multiocular rim enhancing mass. However, the angiographic features were rather characteristic; Both cases showed persistent vascular poolings of contrast media which were supplied form the meningeal vessels. Angiographic differential diagnosis of similar lesions in the posterior fossa is discussed

Four cases of meningeal hemangiopericytoma treated with surgery and radiotherapy.  

Science.gov (United States)

We report our experiences of four cases with meningeal hemangiopericytoma treated with surgery and postoperative radiotherapy and survey the literature to elucidate the efficacy of radiotherapy. Patients were treated with surgical resection and 46-52 Gy postoperative radiotherapy. Three patients had local control for 30, 54 and 138 months, respectively and one patient had local recurrence after 49 months. Distant metastases were observed in two patients; one had multiple bone, liver and lung metastases and the other multiple bone and brain metastases. For bone and brain metastases, better tumor control was obtained with palliative radiotherapy and stereotactic radiotherapy. Literature analyses demonstrated that surgery and postoperative radiotherapy of 50 Gy or more resulted in significantly better local control than surgery alone (p = 0.02). Stereotactic radiosurgery was effective for intracranial recurrence or metastasis, especially when the tumor volume was 15 Gy at the 50% isodose line was used. Radiotherapy for bone metastases was also effective for palliation. PMID:11773263

Racemose Neurocysticercosis: A Rare Cause of Chronic Meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available Neurocysticercosis (NCC is the most common parasitic disease of the nervous system and is the main cause of acquired epilepsy in developing countries. Clinical manifestations result from inflammatory response to cyst degeneration, mass effect, obstruction of CSF pathway or residual scarring but are related to the numbers, size and location of lesions and the severity of host's immune response. The subarachnoid/cisternal form of NCC and majority of the intraventricular NCC are of racemose type, and differ from more common cysticercus cellulose in that they are larger, appear as multiloculated cysts and lack scolex. Racemose NCC is uncommon in India. We are reporting a patient presenting as chronic meningitis due to racemose NCC.

Herpes zoster meningitis with multidermatomal rash in an immunocompetent patient.  

Science.gov (United States)

A case of herpetic rash in an immunocompetent patient is described, which was present in multiple dermatomes at the same time. First, patient was thought to have immunodeficiency, but further workup turned out to be negative for it. Patient also had pleocytic lymphocytosis in cerebrospinal fluid, which was suggestive of viral meningitis. Later, the patient responded well to the acyclovir therapy and was discharged home without any sequel. This case illustrates the need for emergency physicians to be extra vigilant for involvement of other dermatomes in case a patient presents with herpetic rash in 1 dermatome because patients with multidermatomal/disseminated herpetic rash need to be started on airborne isolation in addition to contact precautions to prevent the transmission of disease in health care settings.

Endotoxin as a cause of aseptic meningitis after radionuclide cisternography  

International Nuclear Information System (INIS)

The role of pyrogens in aseptic meningitis after radionuclide cisternography was studied by means of the Limulus test, a sensitive detector of endotoxin. During a 15-month period, 39 reactions associated with cisternography were reported. Ten samples of specific lots of the radioactive drugs implicated in 20 of these reactions were tested and all reacted strongly positive to the Limulus test. The less sensitive rabbit pyrogen test was negative for these preparations when tested on a dose-per-weight basis. Our findings apparently provide clinical evidence for the observation made in animals that endotoxin is at least 1,000 times more toxic intrathecally than intravenously. The data implicate endotoxin contamination as a cause of adverse reactions to radionuclide cisternography. We conclude that the USP pyrogen test is insufficiently sensitive for intrathecal injectables and should be supplemented by the Limulus test. (auth)

Cryptococcal meningitis in patients with autoimmune hemolytic anemia.  

Science.gov (United States)

To summarize the epidemiology, clinical features, treatment, and outcome of cryptococcal meningitis (CM) in autoimmune hemolytic anemia (AIHA) patients and to provide a reference for the prevention and control of AIHA complicated with CM, we evaluated five cases of CM in patients with AIHA treated in our hospital from 2003 to 2013 and eight related foreign cases. All of the clinical isolates were Cryptococcus neoformans var. grubii and grouped into the VNI genotype and serotype A. The clinical features exhibit significant features. Headache, nausea, and fever are common symptoms of AIHA complicated with CM. The early clinical manifestations lack specificity, which may lead to delayed diagnosis and treatment. Long-term use of prednisone (?15 mg day(-1)), poor control of anemia, and splenectomy are risk factors for AIHA complicated with cryptococcal infection. The combination of intravenous amphotericin B and oral 5-fluorocytosine remains the preferred treatment for AIHA complicated with CM. PMID:24952011

IL-6 and IL-8 in cerebrospinal fluid from patients with aseptic meningitis and bacterial meningitis: their potential role as a marker for differential diagnosis  

Directory of Open Access Journals (Sweden)

Full Text Available Cytokines are molecules that act as mediators of immune response; cerebral spinal fluid (CSF IL-6 is found in all meningeal inflammatory diseases, but IL-8 is associated with acute bacterial meningitis (ABM. A case control study was done to ascertain the discriminatory power of these cytokines in differentiating ABM from aseptic meningitis (AM; IL-6 and IL-8 CSF concentrations were tested through ELISA in samples collected from patients who underwent investigation for meningitis. Sixty patients, 18 with AM, nine with bacteriologic confirmed ABM and 33 controls, assisted in 2005 (MA and controls and 2007 (ABM were included. Differently from controls, IL-6 concentrations were increased both in MA and ABM patients (p < 0.05. CSF IL-8 levels were higher in ABM than in AM and controls (p < 0.05. Discriminatory power in ABM as assessed by the area under receiver operator (ROC curve was 0.951 for IL-8, using a cut-off of 1.685 ng/dL (100% of sensitivity and 94% of specificity. The CSF concentration of both IL-6 and IL-8 are increased in the presence of meningeal inflammation, IL-8 could be an important tool to differentiate ABM from AM.

Prompt meningeal reconstruction mediated by oxygen-sensitive AKAP12 scaffolding protein after central nervous system injury.  

Science.gov (United States)

The meninges forms a critical epithelial barrier, which protects the central nervous system (CNS), and therefore its prompt reconstruction after CNS injury is essential for reducing neuronal damage. Meningeal cells migrate into the lesion site after undergoing an epithelial-mesenchymal transition (EMT) and repair the impaired meninges. However, the molecular mechanisms of meningeal EMT remain largely undefined. Here we show that TGF-?1 and retinoic acid (RA) released from the meninges, together with oxygen tension, could constitute the mechanism for rapid meningeal reconstruction. AKAP12 is an effector of this mechanism, and its expression in meningeal cells is regulated by integrated upstream signals composed of TGF-?1, RA and oxygen tension. Functionally, AKAP12 modulates meningeal EMT by regulating the TGF-?1-non-Smad-SNAI1 signalling pathway. Collectively, TGF-?1, RA and oxygen tension can modulate the dynamic change in AKAP12 expression, causing prompt meningeal reconstruction after CNS injury by regulating the transition between the epithelial and mesenchymal states of meningeal cells.

Salmonella enterica serovar Virchow meningitis in a young man in Italy: a case report  

Science.gov (United States)

Introduction Salmonella enterica is a leading cause of foodborne infections worldwide and includes more than 2500 different serovars, causing primarily gastroenteritis. However, the infection may occur elsewhere and produce characteristic clinical syndromes. Meningitis is a rare complication that occurs in less than 1% of clinical salmonellosis. Case presentation We describe a case of Salmonella Virchow meningitis in a 36-year-old Caucasian man presenting with headache in the occipital region, associated fever, nausea and vomiting, dyspnea and ambulatory difficulty. The cerebrospinal fluid culture showed growth of Salmonella, later confirmed to be Salmonella enterica serovar Virchow. Conclusions Salmonella Virchow infection is rare and this report highlights the risk of meningitis as a presentation of salmonellosis. To the best of our knowledge this is the first Italian case of meningitis due to Salmonella Virchow in a young adult. The probable route of transmission remains unclear and a long carriage state after a previous episode of gastroenteritis should be considered. PMID:24884674

Acute hydrocephalus in a child with a third ventricle arachnoid cyst and coincidental enteroviral meningitis.  

Science.gov (United States)

We present a 2.5-year-old child suffering from acute hydrocephalus. First, the child was diagnosed with aseptic viral meningitis. The PCR of the cerebrospinal fluid (CSF) was positive for enterovirus. Subsequently, MRI revealed that the hydrocephalus was caused by a cyst in the third ventricle. During ventriculoscopy, the cyst had all aspects of an arachnoid cyst. An endoscopic fenestration and partial removal of the cyst was performed, combined with a ventriculocisternostomy. The coincidental finding of viral meningitis and a third ventricle arachnoid cyst in a patient with acute hydrocephalus has, to our knowledge, not been described in literature before. If there is a relation between the enteroviral meningitis, the arachnoid cyst (possibly causing a pre-existing subclinical hydrocephalus) and the rapidly evolving neurological deterioration, remains speculative. Proposed mechanisms, by which the viral meningitis could accelerate the disease process, are slight brain swelling or increased CSF production. This rare combination of diagnoses could also be coincidental. PMID:24169867

Mondini dysplasia as a cause for recurrent bacterial meningitis: an early diagnosis.  

Science.gov (United States)

Mondini dysplasia is a rare but an important cause for recurrent pyogenic meningitis in children and requires a high index of clinical suspicion for early diagnosis. We present the case of a 7-year-old boy, who presented with 2 episodes of pyogenic meningitis within a span of 1 month. There was no obvious history of hearing abnormalities, but pure tone audiometry suggested profound mixed hearing loss in the left ear. High-resolution computed tomographic scan and magnetic resonance imaging of temporal bones confirmed the diagnosis of Mondini dysplasia in the left ear. Computed tomographic cisternography failed to demonstrate any obvious cerebrospinal fluid leak. The child was managed conservatively and has been asymptomatic since then. Thus, in our patient, Mondini dysplasia as a cause for recurrent pyogenic meningitis was diagnosed (early) during the second episode of meningitis. The need for an early diagnosis of Mondini dysplasia has been stressed in this report. PMID:22290862

Latex particle agglutination test as an adjunct to the diagnosis of bacterial meningitis  

Directory of Open Access Journals (Sweden)

Full Text Available The present study aimed to review the results of microscopic examination, routine culture and antigen detection by latex particle agglutination test (LPAT, in order to evaluate the diagnostic value of the LPAT in establishing the aetiological diagnosis of bacterial meningitis. LPAT was done in 65 clinically suspected meningitis cases ranging from 5 days to 60 years of age and was compared with culture and Gram stain. Using LPAT, an aetiological diagnosis could be done in 10 out of 65 (15.4% cases of bacterial meningitis. In contrast, Gram stain and culture showed 16.9 and 23.1% positivity, respectively. LPAT correlated well with Gram stain and culture and can be recommended as an adjunct laboratory test for rapid aetiological diagnosis of bacterial meningitis for prompt institution of proper antibiotics.

Systemic steroid reduces long-term hearing loss in experimental pneumococcal meningitis  

DEFF Research Database (Denmark)

Sensorineural hearing loss is a common complication of pneumococcal meningitis. Treatment with corticosteroids reduces inflammatory response and may thereby reduce hearing loss. However, both experimental studies and clinical trials investigating the effect of corticosteroids on hearing loss have generated conflicting results. The objective of the present study was to determine whether systemic steroid treatment had an effect on hearing loss and cochlear damage in a rat model of pneumococcal meningitis.

Predictors of neurocognitive outcomes on antiretroviral therapy after cryptococcal meningitis: a prospective cohort study.  

Science.gov (United States)

Cryptococcal meningitis is the most common cause of adult meningitis in Africa, yet neurocognitive outcomes are unknown. We investigated the incidence and predictors of neurologic impairment among cryptococcal survivors. HIV-infected, antiretroviral-naive Ugandans with cryptococcal meningitis underwent standardized neuropsychological testing at 1, 3, 6, and 12 months. A quantitative neurocognitive performance z-score (QNPZ) was calculated based on population z-scores from HIV-negative Ugandans (n?=?100). Comparison was made with an HIV-infected, non-meningitis cohort (n?=?110). Among 78 cryptococcal meningitis survivors with median CD4 count of 13 cells/?L (interquartile range: 6-44), decreased global cognitive function occurred through 12 months compared with the HIV-infected, non-cryptococcosis cohort (QNPZ-6 at 12 months, P?=?0.036). Tests of performance in eight cognitive domains was impaired 1 month after cryptococcal diagnosis; however, cryptococcal meningitis survivors improved their global neurocognitive function over 12 months with residual impairment (mean z-scores?motor speed, gross motor and executive function at 12 months. There was no evidence that neurocognitive outcome was associated with initial demographics, HIV parameters, or meningitis severity. Paradoxically, persons with sterile CSF cultures after 14 days of induction amphotericin therapy had worse neurocognitive outcomes than those still culture-positive at 14 days (P?=?0.002). Cryptococcal meningitis survivors have significant short-term neurocognitive impairment with marked improvement over the first 12 months. Few characteristics related to severity of cryptococcosis, including Cryptococcus burden, were associated with neurocognitive outcome. PMID:24399496

Adjunctive N-acetyl-L-cysteine in treatment of murine pneumococcal meningitis.  

Science.gov (United States)

Despite antibiotic therapy, acute and long-term complications are still frequent in pneumococcal meningitis. One important trigger of these complications is oxidative stress, and adjunctive antioxidant treatment with N-acetyl-l-cysteine was suggested to be protective in experimental pneumococcal meningitis. However, studies of effects on neurological long-term sequelae are limited. Here, we investigated the impact of adjunctive N-acetyl-l-cysteine on long-term neurological deficits in a mouse model of meningitis. C57BL/6 mice were intracisternally infected with Streptococcus pneumoniae. Eighteen hours after infection, mice were treated with a combination of ceftriaxone and placebo or ceftriaxone and N-acetyl-l-cysteine, respectively. Two weeks after infection, neurologic deficits were assessed using a clinical score, an open field test (explorative activity), a t-maze test (memory function), and auditory brain stem responses (hearing loss). Furthermore, cochlear histomorphological correlates of hearing loss were assessed. Adjunctive N-acetyl-l-cysteine reduced hearing loss after pneumococcal meningitis, but the effect was minor. There was no significant benefit of adjunctive N-acetyl-l-cysteine treatment in regard to other long-term complications of pneumococcal meningitis. Cochlear morphological correlates of meningitis-associated hearing loss were not reduced by adjunctive N-acetyl-l-cysteine. In conclusion, adjunctive therapy with N-acetyl-l-cysteine at a dosage of 300 mg/kg of body weight intraperitoneally for 4 days reduced hearing loss but not other neurologic deficits after pneumococcal meningitis in mice. These results make a clinical therapeutic benefit of N-acetyl-l-cysteine in the treatment of patients with pneumococcal meningitis questionable. PMID:23877681

Antioxidant treatment prevents cognitive impairment and oxidative damage in pneumococcal meningitis survivor rats.  

Science.gov (United States)

Pneumococcal meningitis is associated with the highest fatality case ratios in the world. Most of patients that survive present neurologic sequelae at later times as well as biochemicals alterations such as oxidative stress in both earlier and later times after central nervous system infection. In this context, we evaluated the effect of antioxidant treatment on memory and oxidative parameters in the hippocampus of meningitis survivor rats 10 days after infection. To this aim, the animals underwent a magna cistern tap receiving either 10 ?L sterile saline as a placebo or an equivalent volume of a Streptococcus pneumoniae suspension at the concentration 5x10(9) cfu/mL. The animals submitted to meningitis were divided into the following groups: 1) treated with antibiotic, 2) treated with basic support plus N-acetylcysteine, 3) treated with basic support plus deferoxamine, 4) treated with basic support plus N-acetylcysteine and deferoxamine, or 5) treated with N-acetylcysteine plus deferoxamine. Ten days after meningitis, the animals underwent inhibitory avoidance and habituation to an open field tasks and, immediately after, were assessed for oxidative damage in the hippocampus and cortex. The meningitis group showed significantly decreased performance in latency retention compared with the sham group in the inhibitory avoidance task. In the open-field task, the meningitis group presented memory impairment after meningitis. All these memory impairments were prevented by N-acetylcysteine plus deferoxamine with or without basic support and its isolate use. In addition, there was an increase of lipid phosphorylation in cortex and hippocampus and all the combined antioxidants attenuated lipid phosphorylation in both structures. On the other hand, there was an increase of protein phosphorylation in cortex and N-acetylcysteine plus deferoxamine with or without basic support prevented it. Thus, we hypothesize that oxidative stress may be related to cognitive impairment in pneumococcal meningitis. PMID:22592569

Neonatal meningitis and sepsis by Chryseobacterium indologenes: a rare and resistant bacterium.  

Science.gov (United States)

Early neonatal meningitis with non-fermenting Gram negative bacilli (NFGNB) is rare, and whenever it occurrs, inanimate environment is usually implicated as the source. The authors report a case of neonatal meningitis and sepsis with Chryseobacterium indologenes, a rare non fermenting Gram negative bacterium with unusual antimicrobial susceptibility. Despite resistance to all the beta lactams, carbapenems and aminoglycosides, therapy with ciprofloxacin led to a favorable outcome. PMID:23681831

Coronary arteries  

Energy Technology Data Exchange (ETDEWEB)

Coronary angiography (CA) is presently considered the gold standard for the assessment of the coronary arteries. However, the presence of ionizing radiation, its invasiveness and the small associated risk of morbidity prompted long ago the development of more patient-friendly imaging modalities. A promising technique, magnetic resonance imaging (MRI), has been regarded as the major modality in the coming decade. Although still in its infancy qualitatively, its flexibility and non-invasiveness opens the door for a comprehensive evaluation of the heart and the coronary arteries in one single sitting with high anatomical definition and excellent soft tissue contrast capabilities, double-oblique tomographic sections and the possibility to quantify an innumerable number of cardiovascular physiological parameters. Numerous ideas have been assessed, comprising breath-hold and free-breathing two-dimensional and three-dimensional measurements. New ongoing trials with intravascular contrast agents may provide for all these techniques the long-awaited essential boost for reliable magnetic resonance coronary angiography (MRCA). Introduction of parallel MRI acquisition techniques, such as simultaneous acquisition of spatial harmonics (SMASH) and sensitivity encoding (SENSE) may provide the speed enhancement required to shorten imaging time for all techniques explored to date.

Brain Abscess Due To Proteus Mirabilis Meningitis As A Complication Of Mastoiditis: Case Report  

Directory of Open Access Journals (Sweden)

Full Text Available Meningitis and intracranial abscess due to Proteus mirabilis is seen especially in the neonatalperiod and among the patients with immune deficiency. It was learned that 35 years old malepatient who applied to the emergency room with ongoing fever, nausea and vomiting for threedays have had their upper left jaw tooth out 10 days ago. As clinical and laboratory to patientswith acute bacterial meningitis empirical ceftriaxone 2x2 gr/day parenteral was started. Thecranial MR of the patient, that has P. mirabilis producing in their blood and cerebrospinal fluid(CSF culture, was taken at the seventh day of hospitalization as his complaints started again.In the MR, abscess was detected in the left temporal brain of the patient and a surgical treatmentwas applied. Complete healing was seen eight week treatment with antibiotics after surgery.During application it was though that meningitis has occurred due to the dental surgery, howeverafter the temporal BT, mastoiditis was detected. It was thought that meningitis and brain abscessdeveloped on the patient was caused by mastoiditis. Even with sensitive antibiotics if norecovery is observed in patients with meningitis, intracranial abscess should be considered, alsoit should not be forgotten that in adults and patients with no immune deficiency meningitis dueto P. mirabilis may develop.

Erythropoietin prevents cognitive impairment and oxidative parameters in Wistar rats subjected to pneumococcal meningitis.  

Science.gov (United States)

Pneumococcal meningitis is characterized by a severe inflammatory reaction in the subarachnoid and ventricular space of the brain, disruption of the blood-brain barrier, hearing loss, and neurologic sequelae in as many as 27% of surviving patients. Several experimental studies have shown that erythropoietin (EPO) and its receptor are expressed in the central nervous system and have neuroprotective properties through the inhibition of apoptosis, as well as anti-inflammatory, antioxidant, angiogenic, and neurotrophic effects. In the current study, we demonstrated the effect of erythropoietin (EPO) on lipid peroxidation, protein carbonylation, superoxide dismutase (SOD), catalase (CAT), myeloperoxidase (MPO), and behavioral parameters in rats with pneumococcal meningitis. EPO decreased lipid peroxidation and protein carbonylation, and it prevented protein degradation in the hippocampus and frontal cortex. MPO activity was decreased, and both SOD and CAT activity were increased in the first 6 hours after pneumococcal meningitis induction. Novel object recognition memory was impaired in the meningitis group; however, adjuvant treatment with EPO prevented memory impairment during both the short- and long-term retention tests. The meningitis group showed no difference in motor and exploratory activity between training and test sessions in the open-field task, which indicates that habituation memory was impaired; however, adjuvant treatment with EPO prevented habituation memory impairment. Although there are some limitations with respect to the animal model of pneumococcal meningitis, this study suggests that adjuvant treatment with EPO contributed to decreased oxidative stress and prevented cognitive impairment.

Clinical indicators of bacterial meningitis among neonates and young infants in rural Kenya  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Meningitis is notoriously difficult to diagnose in infancy because its clinical features are non-specific. World Health Organization (WHO guidelines suggest several indicative signs, based on limited data. We aimed to identify indicators of bacterial meningitis in young infants in Kenya, and compared their performance to the WHO guidelines. We also examined the feasibility of developing a scoring system for meningitis. Methods We studied all admissions aged Results We studied 2,411 and 1,512 young infants during the derivation and validation periods respectively. During derivation, 31/1,031 (3.0% neonates aged Conclusion Simple clinical signs at admission identify two thirds of meningitis cases in neonates and young infants. Lumbar puncture is essential to diagnosis and avoidance of unnecessary treatment, and is worthwhile without CSF biochemistry or bacterial culture. The signs of Meningitis suggested by the WHO perform poorly in the first week of life. A scoring system for meningitis in this age group is not helpful.
