RESUMO

Abstract Idiopathic hypertrophic pachymeningitis is rare cause of neurological symptoms with myelopathy due to spinal cord compression. We report a case of pachymeningitis, which was manifested primarily by tetraparesis after low-energy trauma and recurrence the myelopathy symptoms after 5 years of surgery. The patient, a 19-year-old woman, was subjected to extensive investigation without evidence of any underlying disease. A meningeal biopsy was performed and showed an unspecific inflammatory process with extensive fibrosis of the dura mater. These findings, associated with the exclusion of other causes, suggest idiopathic hypertrophic pachymeningitis.


Resumo A paquimeningite hipertrófica idiopática é uma causa rara de sintomas neurológicos apresentando mielopatia por compressão da medula espinhal. Relatamos um caso de paquimeningite com manifestação primária de tetraparesia após trauma de baixa energia e recorrência dos sintomas de mielopatia 5 anos após a cirurgia. A paciente, uma mulher de 19 anos, foi submetida a extensa investigação sem evidências de qualquer doença de base. Uma biópsia da meninge revelou processo inflamatório inespecífico com extensa fibrose da dura máter, também visualizado no período perioperatório. Esses achados, associados à exclusão de outras causas, sugerem o diagnóstico de paquimeningite hipertrófica idiopática.

RESUMO

OBJECTIVE: The concept of otitis media with ANCA-associated vasculitis (OMAAV) was recently proposed by the study group of the Japan Otological Society. However, little is known about the effect of ear involvement on the clinical features and prognosis of AAV. We investigate this issue in this study. METHODS: We retrospectively examined 36 patients diagnosed with OMAAV and 44 patients diagnosed with AAV without ear involvement (non-OMAAV) at Ehime University Hospital from 2013 to 2018. We collected serological findings including ANCA type and titer, C-reactive protein (CRP), serum creatinine level, organ involved at initial diagnosis, treatment, remission, disease relapse, and mortality from medical records. We investigated whether clinical features and outcomes differed between the OMAAV and non-OMAAV groups. RESULTS: Age, ANCA titer, and CRP at initial diagnosis were not significantly different between the two groups, and the rate of intravenous cyclophosphamide (IVCY) use also did not differ. The proportions of patients with concurrent eye involvement, facial palsy (FP), and hypertrophic pachymeningitis (HCP) were significantly higher in the OMAAV than in the non-OMAAV group (p = 0.005, 0.005 and 0.049, respectively), while both renal and peripheral nerve involvement were significantly less common in OMAAV patients (p = 0.04). Among the 30 patients with renal involvement, serum creatinine level at diagnosis was significantly lower in the OMAAV group (p = 0.04). The mortality rate was 8.3% in OMAAV and 6.8% in non-OMAAV cases, but this difference was not significant. The rate of relapse was 33.3% in OMAAV and 13.6% in non-OMAAV cases; this difference was significant (p = 0.04). CONCLUSIONS: Serological measurements of disease activity did not differ between the groups. Eye involvement, FP, and HCP, however, were significantly more common in AAV with ear involvement. In addition, renal involvement was less common and renal impairment was milder in AAV with ear involvement. These findings can be considered clinical features. The relapse rate was significantly higher in AAV with ear involvement.

RESUMO

INTRODUCTION: Polymerase chain reaction (PCR)-based testing of cerebrospinal fluid (CSF) samples has greatly facilitated the diagnosis of central nervous system (CNS) infections. However, the clinical significance of Epstein-Barr virus (EBV) DNA in CSF of individuals with suspected CNS infection remains unclear. We wanted to gain a better understanding of EBV as an infectious agent in immunocompetent patients with CNS disorders. METHODS: We identified cases of EBV-associated CNS infections and reviewed their clinical and laboratory characteristics. The study population was drawn from patients with EBV PCR positivity in CSF who visited Pusan National University Hospital between 2010 and 2019. RESULTS: Of the 780 CSF samples examined during the 10-year study period, 42 (5.4 %) were positive for EBV DNA; 9 of the patients (21.4 %) were diagnosed with non-CNS infectious diseases, such as optic neuritis, Guillain-Barré syndrome, and idiopathic intracranial hypotension, and the other 33 cases were classified as CNS infections (22 as encephalitis and 11 as meningitis). Intensive care unit admission (13/33 patients, 39.3 %) and presence of severe neurological sequelae at discharge (8/33 patients, 24.2 %) were relatively frequent. In 10 patients (30.3 %), the following pathogens were detected in CSF in addition to EBV: varicella-zoster virus (n = 3), cytomegalovirus (n = 2), herpes simplex virus 1 (n = 1), herpes simplex virus 2 (n = 1), Streptococcus pneumomiae (n = 2), and Enterococcus faecalis (n = 1). The EBV-only group (n = 23) and the co-infection group (n = 10) did not differ in age, gender, laboratory data, results of brain imaging studies, clinical manifestations, or prognosis; however, the co-infected patients had higher CSF protein levels. CONCLUSION: EBV DNA in CSF is occasionally found in the immunocompetent population; the virus was commonly associated with encephalitis and poor prognosis, and frequently found together with other microbes in CSF.

RESUMO

Calvarial tuberculosis is very rare accounting for 0.2-1.3% of skeletal tuberculosis. Diagnosis is also challenging in these areas due to insidious onset of presentation, low bacterial loads in these sites and unapproachable locations for sample collection. Rarely these patients may presents with features of meningitis when the adjacent meninges are involved. Here we describe a case where tubercular involvement of sphenoid, clivus, and frontal bone, who presented as chronic meningitis and diagnosis was made on the basis of radiological and histopathological findings. All the lesions almost resolved following antitubercular treatment at 5 months follow up. A high index of suspicion is needed for early diagnosis and management of this condition.

RESUMO

OBJECTIVE: To describe neuroimaging findings and to report the epidemiologic and clinical characteristics of patients with coronavirus disease 2019 (COVID-19) with neurologic manifestations. METHODS: In this retrospective multicenter study (11 hospitals), we included 64 patients with confirmed COVID-19 with neurologic manifestations who underwent a brain MRI. RESULTS: The cohort included 43 men (67%) and 21 women (33%); their median age was 66 (range 20-92) years. Thirty-six (56%) brain MRIs were considered abnormal, possibly related to severe acute respiratory syndrome coronavirus. Ischemic strokes (27%), leptomeningeal enhancement (17%), and encephalitis (13%) were the most frequent neuroimaging findings. Confusion (53%) was the most common neurologic manifestation, followed by impaired consciousness (39%), presence of clinical signs of corticospinal tract involvement (31%), agitation (31%), and headache (16%). The profile of patients experiencing ischemic stroke was different from that of other patients with abnormal brain imaging: the former less frequently had acute respiratory distress syndrome (p = 0.006) and more frequently had corticospinal tract signs (p = 0.02). Patients with encephalitis were younger (p = 0.007), whereas agitation was more frequent for patients with leptomeningeal enhancement (p = 0.009). CONCLUSIONS: Patients with COVID-19 may develop a wide range of neurologic symptoms, which can be associated with severe and fatal complications such as ischemic stroke or encephalitis. In terms of meningoencephalitis involvement, even if a direct effect of the virus cannot be excluded, the pathophysiology seems to involve an immune or inflammatory process given the presence of signs of inflammation in both CSF and neuroimaging but the lack of virus in CSF.

RESUMO

BACKGROUND: The clinical spectrum of myelin oligodendrocyte glycoprotein (MOG)-antibody-associated disease is expanding. OBJECTIVE: To describe an unusual case of MOG-antibody-associated hypertrophic pachymeningitis (HP). METHODS: Case study. RESULTS: A 57-year-old female presented with a generalised seizure on a background of 3 months history of progressive cognitive decline and behavioural changes. Brain Magnetic Resonance Imaging (MRI) revealed widespread pachymeningeal enhancement and hyperintense signal in both hippocampi. Cerebrospinal Fluid (CSF) examination was normal. The patient was found positive for MOG-antibody. She clinically improved with steroids and the MRI abnormalities completely resolved. CONCLUSIONS: Clinicians might consider testing for MOG-antibody in cases with HP.

RESUMO

Headache is a significant reason for access to Emergency Departments (ED) worldwide. Though primary forms represent the vast majority, the life-threatening potential of secondary forms, such as subarachnoid hemorrage or meningitis, makes it imperative for the ED physician to rule out secondary headaches as first step, based on clinical history, careful physical (especially neurological) examination and, if appropriate, hematochemical analyses, neuroimaging or lumbar puncture. Once secondary forms are excluded, distinction among primary forms should be performed, based on the international headache classification criteria. Most frequent primary forms motivating ED observation are acute migraine attacks, particularly status migrainous, and cluster headache. Though universally accepted guidelines do not exist for headache management in an emergency setting, pharmacological parenteral treatment remains the principal approach worldwide, with NSAIDs, neuroleptic antinauseants, triptans and corticosteroids, tailored to the specific headache type. Opioids should be avoided, for their scarce effectiveness in the acute phase, while IV hydration should be limited in cases of ascertained dehydration. Referral of the patient to a Headache Center should subsequently be an integral part of the ED approach to the headache patients, being ascertained that lack of this referral involves a high rate of relapse and new accesses to the ED. More controlled studies are needed to establish specific protocols of management for the headache patient in the ED.

RESUMO

Infection by the fungal pathogen Cryptococcus neoformans causes lethal meningitis, primarily in immune-compromised individuals. Colonization of the brain by C. neoformans is dependent on copper (Cu) acquisition from the host, which drives critical virulence mechanisms. While C. neoformans Cu+ import and virulence are dependent on the Ctr1 and Ctr4 proteins, little is known concerning extracellular Cu ligands that participate in this process. We identified a C. neoformans gene, BIM1, that is strongly induced during Cu limitation and which encodes a protein related to lytic polysaccharide monooxygenases (LPMOs). Surprisingly, bim1 mutants are Cu deficient, and Bim1 function in Cu accumulation depends on Cu2+ coordination and cell-surface association via a glycophosphatidyl inositol anchor. Bim1 participates in Cu uptake in concert with Ctr1 and expression of this pathway drives brain colonization in mouse infection models. These studies demonstrate a role for LPMO-like proteins as a critical factor for Cu acquisition in fungal meningitis.

RESUMO

Rheumatoid arthritis (RA) is a multisystem inflammatory disease which can involve many organ systems including the central nervous system (CNS). Though not very common, the results can be severely debilitating. The spectrum of the CNS involvement includes meningitis, encephalitis and occasionally rheumatoid nodules. Its presentation is variable, though very rarely it can present as focal neurological deficits. Imaging can be suggestive, but diagnosis usually requires tissue biopsy. Treatment consists of high-dose steroids and immunosuppressants. We describe the case of a 55-year-old male patient with a history of RA presenting with a third nerve palsy and headache who was found to have rheumatoid nodules on biopsy. CNS involvement in RA should be considered in anyone with rheumatoid arthritis who presents with focal neurological deficits, though infections and space-occupying lesions should also be ruled out.

RESUMO

Behçet's disease (BD) is a rare systemic vasculitis disorder of unknown etiology characterized by recurrent oral and genital apthae and uveitis. It involves the central or peripheral nervous system; occurs rarely during childhood. Isolated acute aseptic meningitis is extremely uncommon. We report here a case of Neuro-Behçet disease (NBD) diagnosed in a 14-year-old girl. The patient presented acute headache, diplopia, papilla edema, and meningeal irritation. She had a history of recurrent oral ulcers. Brain magnetic resonance imaging revealed pachymeningitis. Pleocytosis and pressure increase were the cerebrospinal fluid findings. Although medical therapy, her complaints were not resolved. Uveitis was not detected, pathergy test was negative. HLA-B51 allele was positive. The findings were considered to unusual NBD. The patient improved dramatically after steroid therapy. BD should be considered in differential diagnosis of meningitis unless an infectious agent is demonstrated. To our knowledge, a case of pachymeningitis with NBD, was not described in children.


La enfermedad de Behçet (EB) es un trastorno de vasculitis sistémica poco frecuente, de etiología desconocida, que se caracteriza por la presencia de aftas bucales, úlceras genitales y uveítis recurrentes. Afecta los sistemas nerviosos central y periférico; raramente se produce durante la niñez. La meningitis aséptica aguda aislada es muy poco frecuente. En este artículo, se describe el caso de una paciente de 14 años con diagnóstico de enfermedad de Behçet con afectación neurológica (neuro- Behçet). La paciente tenía cefalea aguda, diplopia, papiledema e irritación meníngea. Tenía antecedentes de úlceras bucales recurrentes. Las imágenes por resonancia magnética de cerebro revelaron paquimeningitis. Los hallazgos en el líquido cefalorraquídeo fueron pleocitosis y aumento de la presión. Pese al tratamiento médico, sus síntomas no se resolvieron. No se detectó uveítis y la prueba de patergia fue negativa. El alelo HLA-B51 fue positivo. Se consideró que los hallazgos apuntaban a la poco frecuente enfermedad de Behçet con afectación neurológica. La paciente mejoró drásticamente luego del tratamiento con corticoesteroides. En el diagnóstico diferencial de meningitis, se debe considerar la EB, a menos que se demuestre la presencia de un agente infeccioso. Hasta donde sabemos, anteriormente no se había descrito un caso de paquimeningitis con neuro-Behçet en la población pediátrica.

RESUMO

In this paper, we proposed a deterministic model of pneumonia-meningitis coinfection. We used a system of seven ordinary differential equations. Firstly, the qualitative behaviours of the model such as positivity of the solution, existence of the solution, the equilibrium points, basic reproduction number, analysis of equilibrium points, and sensitivity analysis are studied. The disease-free equilibrium is locally asymptotically stable if the basic reproduction number is kept less than unity, and conditions for global stability are established. Then, the basic model is extended to optimal control by incorporating four control interventions, such as prevention of pneumonia as well as meningitis and also treatment of pneumonia and meningitis diseases. The optimality system is obtained by using Pontryagin's maximum principle. For simulation of the optimality system, we proposed five strategies to check the effect of the controls. First, we consider prevention only for both diseases, and the result shows that applying prevention control has a great impact in bringing down the expansion of pneumonia, meningitis, and their coinfection in the specified period of time. The other strategies are prevention effort for pneumonia and treatment effort for meningitis, prevention effort for meningitis and treatment effort for pneumonia, treatment effort for both diseases, and using all interventions. We obtained that each of the listed strategies is effective in minimizing the expansion of pneumonia-only, meningitis-only, and coinfectious population in the specified period of time.

RESUMO

BACKGROUND: The underlying physiology of the intracranial pressure (ICP) curve morphology is still poorly understood. If this physiology is explained it could be possible to extract clinically relevant information from the ICP curve. The venous outflow from the cranial cavity is pulsatile, and in theory the pulsatile component of venous outflow from the cranial cavity should be attenuated with increasing ICP. In this study, we explored the relationship between ICP and the pulsatility of the venous outflow from the intracranial cavity. METHODS: Thirty-seven neuro-intensive care patients that had been examined with phase-contrast magnetic resonance imaging regarding cerebral blood flow (CBF) through the internal carotid and vertebral arteries and venous flow in the internal jugular veins were retrospectively included. The pulsatility of the jugular flow was determined by calculating the venous pulsatile index. The results were correlated to clinical data registered in the patient data monitoring system, including ICP and cerebral perfusion pressure (CPP). RESULTS: CBF was 996 ± 298 ml/min, and the flow in the internal jugular veins equaled 67 ± 17% of the CBF, with a range of 22-97%. The venous pulsatile index correlated negatively to ICP (R = - 0.47 p = 0.003). The lowest flow in the internal jugular veins over the cardiac cycle (Fmin) was not correlated to ICP. Temperature, end-tidal CO2, MAP, and CPP were not correlated to venous pulsatility. CONCLUSION: An increase in ICP correlates to a lower pulsatility of the venous outflow from the cranial cavity. A lower pulsatility could be due to increased pressure requirements to compress intracranial veins with increasing ICP.

RESUMO

Here we reported a Chinese case of bilateral peripheral facial paralysis (PFP) in human immunodeficiency virusc (HIV) infected population. A 38-year-old homosexual male patient was referred to our hospital for bilateral facial paralysis. 21 days prior to admission he had developed high fever, chills, headache, fatigue, general malaise, nausea and vomiting. Neurological examination revealed bilateral ptosis of lower lip and cheeks, as well as failure of bilateral eyes closure. Analysis of cerebrospinal fluid (CSF) revealed pleocytosis, a marked rise of micro total protein and a marked rise of intrathecal lgG synthesis. The result of HIV-1 serology was positive by ELISA and that was confirmed by western blot. His CD4 + cell count was 180 cells/mm 3. HIV-1 viral load in CSF was almost 10 times higher than that in plasma. The patient's condition improved steadily and experienced complete resolution of bilateral PFP after 2 months.

RESUMO

The study included 64 patients with serous meningitis, in which the heart rate variability (HRV) spectrum, the content of ACTH and STH in serum was studied in the course of the commonly accepted treatment. The purpose of the study was to analyze the dynamics of indicators of functional state of the autonomic nervous system in correlation with changes of adrenocorticotropic and somatotropic hormones in patients with serous meningitis. According to the results, serous meningitis were predominantly moderate in severity, with generalization in the clinical picture dominated through general toxicosis, general cerebral and meningeal syndromes, but changes in the spectral parameters of HRV showed a marked imbalance with a shift in the functional activity of the autonomic nervous system towards vagotonia in combination with an ACTH level increase and STH decrease in serum (p<0.01).

RESUMO

Objective: Immunoglobulin (Ig)G4-related disease is a major cause of hypertrophic pachymeningitis (HP), presenting as a progressive thickening of the dura mater. HP lacks an animal model to determine its underlying mechanisms. We developed a suitable animal model for the treatment of HP. Methods: We longitudinally evaluated dura in mice with a mutation (Y136F) in the linker for activation of T cells (LAT), which induced type 2 T helper (Th2) cell proliferation and IgG1 (IgG4 human equivalent) overexpression. Mice were therapeutically administered daily oral irbesartan from 3 to 6 weeks of age. Human IgG4-related, anti-neutrophil cytoplasmic antibody-related, and idiopathic HP dura were also immunohistochemically examined. Results: LATY136F mice showing dural gadolinium enhancement on magnetic resonance imaging had massive infiltration of B220+ B cells, IgG1+ cells, CD138+ plasma cells, CD3+ T cells, F4/80+ macrophages, and polymorphonuclear leukocytes in the dura at 3 weeks of age, followed by marked fibrotic thickening. In dural lesions, transforming growth factor (TGF)-ß1 was produced preferentially in B cells and macrophages while TGF-ß receptor I (TGF-ß RI) was markedly upregulated on fibroblasts. Quantitative western blotting revealed significant upregulation of TGF-ß1, TGF-ß RI, and phosphorylated SMAD2/SMAD3 in dura of LATY136F mice aged 13 weeks. A similar upregulation of TGF-ß RI, SMAD2/SMAD3, and phosphorylated SMAD2/SMAD3 was present in autopsied dura of all three types of human HP. Irbesartan abolished dural inflammatory cell infiltration and fibrotic thickening in all treated LATY136F mice with reduced TGF-ß1 and nonphosphorylated and phosphorylated SMAD2/SMAD3. Interpretation: TGF-ß1/SMAD2/SMAD3 pathway is critical in HP and is a potential novel therapeutic target.

RESUMO

RESUMO Objetivo: Relatar um caso raro de uma criança com meningite associada a pericardite na doença pneumocócica invasiva. Descrição do caso: Este relato descreve uma evolução clínica desfavorável de um lactente feminino de 6 meses de idade, previamente hígido, que apresentou inicialmente sintomas respiratórios e febre. A radiografia de tórax revelou um aumento da área cardíaca sem alterações radiográficas nos pulmões. Após a identificação do derrame pericárdico, o paciente apresentou convulsões e entrou em coma. Pneumonia foi descartada durante a investigação clínica. Contudo, foi identificado Streptococcus pneumoniae nas culturas de líquor e sangue. O exame neurológico inicial foi compatível com morte encefálica, posteriormente confirmada pelo protocolo. Comentários: A pericardite purulenta tornou-se uma complicação rara da doença pneumocócica invasiva desde o advento da terapia antibiótica. Pacientes com pneumonia extensa são primariamente predispostos e, mesmo com tratamento adequado e precoce, estão sujeitos a altas taxas de mortalidade. A associação de meningite pneumocócica e pericardite é incomum e, portanto, de difícil diagnóstico. Por isso, uma alta suspeição diagnóstica é necessária para instituir o tratamento precoce e aumentar a sobrevida.


ABSTRACT Objective: To report a rare case of a child with invasive pneumococcal disease that presented meningitis associated with pericarditis. Case description: This report describes the unfavorable clinical course of a previously healthy 6-months-old female infant who initially presented symptoms of fever and respiratory problems. A chest X-ray revealed an increased cardiac area with no radiographic changes in the lungs. After identifying a pericardial effusion, the patient experienced seizures and went into coma. Pneumonia was excluded as a possibility during the clinical investigation. However, Streptococcus pneumoniae was identified in the cerebrospinal fluid and blood cultures. An initial neurological examination showed that the patient was brain dead, which was then later confirmed according to protocol. Comments: Purulent pericarditis has become a rare complication of invasive pneumococcal disease since the advent of antibiotic therapy. Patients with extensive pneumonia are primarily predisposed and, even with early and adequate treatment, are prone to high mortality rates. The association of pneumococcal meningitis and pericarditis is uncommon, and therefore difficult to diagnose. As such, diagnostic suspicion must be high in order to institute early treatment and increase survival.

RESUMO

We report the case of a 66-year-old man with seropositive rheumatoid arthritis who developed neurologically asymptomatic rheumatoid meningitis (RM) revealed by MRI. RM worsened and chest CT showed pericardial effusion, pleural effusion, and bilateral consolidation, and his serum C3 level was decreased. We diagnosed systemic rheumatic vasculitis based on these findings. After a review of more than 20 previously reported cases of RM, this is the first case of RM without central nerve system symptoms.

RESUMO

OBJECTIVE: To explore the clinical and imaging features of patients with hypertrophic cranial pachymeningitis (HCP). METHODS: A retrospective study was performed on 22 patients with HCP diagnosed at the Affiliated Hospital of Xuzhou Medical University from February 2014 to September 2017. RESULTS: A headache was present as an initial symptom in 18 patients. The headache was associated with the loss of vision (2 cases), facial pain (1 case), and unsteady walking (1 case). Other symptoms included cranial nerve dysfunction (15 cases), cerebellar ataxia (4 cases), and sinus thrombosis (3 cases). In the laboratory tests, 7 patients showed an increased number of white blood cells, higher levels of C-reaction protein (CRP), and erythrocyte sedimentation rate (ESR). An elevated level of immunoglobulin G4 (IgG4) and the presence of the anti-neutrophil cytoplasmic antibody (ANCA) were found in 3 and 2 patients respectively. There were 17 patients who had abnormalities in their cerebrospinal fluid (CSF) on lumbar puncture. On magnetic resonance imaging (MRI), a local or generalized thickening was observed in the cerebral falx, the tentorium of the cerebellum, the fronto-parietal lobe, the occipito-parietal lobe, and the dura of skull base. A dural biopsy obtained in one case showed a variety of inflammatory changes. An immunohistochemical analysis revealed the positivity of CD138, IgG, and IgG4 in some cells. All 22 patients had a good response to corticosteroids. CONCLUSION: HCP mainly leads to a headache and the paralysis of multiple cranial nerves. A biopsy and MRI are often required and serve as the basis for the diagnosis and effective therapy.
