Neurologic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can present with fever, headache, and meningism.

Background: Pituitary apoplexy (PA) is a rare but potentially life-threatening condition that may require urgent surgical intervention.Case Presentation: We report a case of a patient who was initially diagnosed with meningoencephalitis (ME) based on clinical presentation and cerebrospinal fluid (CSF) analysis, but was eventually diagnosed with PA. We present a summary of other cases reported in the literature of PA mimicking ME and analyze their clinical features and CSF findings.Results: Among all 22 PA cases reviewed, headache was the most commonly reported symptom. Hypopituitarism was seen in 94.4% of the cases; of these, panhypopituitarism was noted in 38.9%. The sensitivity of magnetic resonance image (MRI) for detecting PA was 94.7%, much higher than that of computed tomography (CT), which was only 31.6%. Neutrophil predominant pleocytosis was present in all cases with a neutrophil percentage ranging from 73% to 98%. CSF leukocyte count was less than 1000/ul in 86% of the cases. CSF erythrocytosis was seen in 92.9% of the cases with a count ranging from 15 to 2030/ul. Elevated CSF protein was present in all cases with a range of 69.8 to 239 mg/dl. CSF glucose level varied with a range between 12 and 136 mg/dl; the level was greater than 40 mg/dl in 73% of the cases.Conclusion: PA tends to be misdiagnosed as ME due to the similarities of semiology and CSF findings. PA should be considered in refractory acute headache cases, especially those with visual and endocrine abnormalities. Early recognition and treatment may lead to significant reduction in morbidity and mortality.Abbreviations: ACTH: adrenocorticotropic hormone; CSF: cerebrospinal fluid; CT: computed tomography; GRE: gradient echo; HRT: hormone replacement therapy;HSV: Herpes Simplex Virus; IV: intravenous; ME: meningoencephalitis; MRI: magnetic resonance image; PA: pituitary apoplexy; RBC: red blood cell; WBC: white blood cell.

Clinical case A 31-year-old right-handed man was transferred by ambulance after falling out of bed. His wife reported that he was agitated, not moving his left side, appeared ‘blue in the face’ and complained that he could not see properly. He had a history of seronegative inflammatory arthritis and keratitis. On arrival at the emergency department, he was significantly agitated and required anaesthetic support for sedation and intubation. Further collateral history found that in the 10 days before admission, he had reported increasing joint pain and swelling, neck stiffness and general malaise. His regular medications were paracetamol and naproxen. Combination therapy for his seronegative inflammatory arthritis in the form of methotrexate and sulfasalazine had been stopped 2 weeks before due to routine blood monitoring identifying deranged liver function tests. On neurological examination, he was encephalopathic and could not follow commands. He had normal pupillary responses and funduscopic appearances. There was no gaze preference, facial weakness or meningism. His muscle tone was normal, and strength testing in the context of poor cooperation found no lateralising weakness. Limb reflexes were symmetrically present, and plantar responses were bilaterally extensor. ### What is the most likely clinical syndrome? We suspected that he had experienced a generalised seizure, given the description of central cyanosis and altered mental state with agitation. The initial witness account of left-sided weakness suggested either a right hemispheric lesion or a Todd’s phenomenon. The prodromal symptoms of neck stiffness and altered mental state with suspected seizure made meningoencephalitis the most likely diagnosis. We started ceftriaxone and acyclovir promptly in the emergency department, …

Background and purpose The purpose of this study was to elucidate the association between aseptic meningitis and jolt accentuation of headache (JAH) in adults. Subjects and method 87 patients with meningeal irritation (age; 35.6 ± 13.3 years old, 45 males) who were admitted to our hospital from 1st August 2013 to 31st August 2018 were included. The diagnosis was determined according to the following criteria:, aseptic meningitis was defined as cerebrospinal fluids (CSF) pleocytosis with no evidence of bacterial infection, fungal infection or carcinomatous findings; meningism was defined as the absence of CSF pleocytosis. None of these patients had consciousness disturbance and focal neurological abnormalities. The blood and CSF data were reviewed for analysis. Results 61 patients were in aseptic meningitis group, 26 patients were in meningism group. Multiple logistic regression analysis showed older age (OR 1.059, 95% Confidence interval (CI) 1.012-1.108, P = 0.013), lower CRP (OR 0.803, 95%CI 0.697-0.925, P = 0.002) and absence of JAH (OR 0.048, 95%CI 0.004-0.554, P = 0.015) were significantly associated with aseptic meningitis. The sensitivity and specificity of JAH in aseptic meningitis were 68.9%, 3.8%.

Background The neurological effects of Lyme borreliosis in children are varied and their clinical progression is not widely reported in the French literature. We carried out a retrospective study to describe the clinical characteristics of Lyme neuroborreliosis in children in southwest France and their clinical progression at 6 months. Methods This study was carried out at Toulouse University Hospital during the period 2006–2017 using patient records. Case definition was based on the combined French clinical and laboratory diagnostic criteria. Results In total, 26 children were included. The median age was 8 years (4–14 years). The different neurological symptoms reported were: meningoradiculitis (62%), which was usually associated with facial palsy (54%); isolated facial palsy (15%); isolated meningitis (8%); polyradiculoneuritis (4%); benign intracranial hypertension (4%) and myelomeningoradiculitis (4%). The most common functional symptoms were headaches (54%), the perception of asthenia (42%), neck pain (27%), and a loss of appetite (19%). Patients with laboratory meningitis (84%) often had no signs of meningism or headaches (38%). Conclusion The majority of the cases involved meningoradiculitis but other, less common, neurological conditions have been described. The clinical signs suggestive of meningitis are not very marked and might delay the diagnosis.

Our team was referred a 14-year-old, previously healthy, immunised aboriginal boy from a remote community in northern Western Australia. He had been admitted to the local community hospital 10 days previously and while there developed haemoptysis, fever and epigastric abdominal pain so was transferred to our care at the regional hospital for ongoing investigation and management. Haemoptysis is an uncommon presentation in adolescence. It can be caused by infection (eg, bronchiectasis, pneumonia, lung abscess or tuberculosis), trauma (eg, lung contusion, foreign body or inhalation injury), vascular disorders (eg, pulmonary embolus, arteriovenous malformation or haemangioma), late complications of congenital lung malformations, coagulopathy or one of the diffuse alveolar haemorrhage syndromes.1 Additionally, bleeding from the upper airway or gastrointestinal tract can mimic haemoptysis. Demographic considerations are important in this case. Bronchiectasis and rheumatic heart disease, both of which may present with haemoptysis, have increased prevalence in aboriginal children in Australia. In addition, Burkholderia pseudomallei is endemic and pulmonary infection can mimic tuberculosis. An infectious aetiology is favoured here in view of the history of fever. He had initially been admitted to the local hospital with presumed bacterial meningitis following presentation with headache, fever and meningism 10 days prior. Cerebrospinal fluid (CSF) prior to antibiotics demonstrated elevated white cell count (WCC) 550/mm3 (90% neutrophils) and protein (0.84 g/L), with negative microscopy and culture for bacteria, and negative PCR testing for bacteria and viruses. Intravenous ceftriaxone (ongoing) and dexamethasone 0.15 mg/kg four times a day (total 4 days) had been administered, with rapid resolution of symptoms. Following transfer to our care (day 1), examination showed normal respiratory rate and oxygen saturations (SaO2=98%); a productive cough with a moderate amount of blood-stained sputum was noted. The respiratory examination (including upper airway) was otherwise unremarkable. There was mild right upper quadrant abdominal tenderness …

Behcet’s disease (BD) is a clinical syndrome characterised by systemic vasculitis commonly involving the central nervous system.[1][1] However, brain stem involvement is less pronounced.[2][2] The lack of definitive conclusive tests with prime dependence on clinical criteria led to low

We diagnosed varicella zoster virus (VZV) meningitis in a healthy adolescent boy who presented without a rash or fever. We aim to compare VZV reactivation meningitis in children after primary VZV infection and VZV vaccination. We reviewed the literature up until June 2020 using Pubmed/MEDLINE and EMBASE databases using 'varicella zoster', 'meningitis' and 'children' as keywords. Only English articles were included. Twenty-five cases were included in this review. Children who had VZV reactivation meningitis after vaccination were younger (7 ± 3.4 years vs. 11.9 ± 3.6 years, P = 0.0038), had a shorter interval between first exposure to reactivation (5.6 ± 2.9 years vs. 8.8 ± 3.2 years, P = 0.018) and more likely to have a rash (100% vs. 55%, P = 0.04). VZV reactivation meningitis occurs after both primary VZV infection and VZV vaccination. The absence of exanthem, fever or meningism does not rule out VZV meningitis.

A 31-year-old man, previously well and in full-time employment was admitted as an emergency following a convulsive seizure, with a 5-day history of headache, altered behaviour and drowsiness. He had an established history of episodic migraine with aura, and his symptoms this time had begun with what he regarded as a ‘typical’ migraine: opaque, spectral lines in the visual periphery, progressing to a hemicranial headache, with associated photophobia, nausea and motion sensitivity, sufficient for him to take time off work. Two days into his illness, his general practitioner prescribed naproxen 250 mg three times a day. Over the next 3 days his headache persisted and his wife reported alteration in his behaviour. He was intermittently drowsy, distractible and confused. Five days into his illness he had a generalised seizure from sleep, precipitating his hospital admission. On examination in the emergency department, he was afebrile; his Glasgow Coma Scale score was 10/15 (E3 V2 M5), which improved to 13/15 (E4 V4 M5) over the ensuing hours. A CT scan of head was normal. He had an elevated serum creatinine (145 µmol/L (60–110)) and urea, a serum C reactive protein of 45 mg/L (

Viral meningitis is mainly caused by non-polio enteroviruses (NPEV). Large-scale data on the clinical characteristics between different outbreaks within the same region are lacking. This study aimed to analyse a possible influence of the circulating NPEV genotype on the disease outcome of affected children. A retrospective cohort study analysing two major outbreaks of NPEV meningitis in Germany in 2008 and 2013 was conducted in cooperation with the National Reference Centre for Poliomyelitis and Enteroviruses (NRC PE) and five German children's hospitals. A total of 196 patients with laboratory-confirmed NPEV meningitis were enrolled. In 2008, children with NPEV meningitis had significantly higher fever and showed more behavioural changes and less back pain. To better define typical findings in echovirus 30 (E-30) meningitis, patients were split into the following three groups: E-30 positive patients, patients with "Non E-30" infection and patients with "Untyped" NPEV infection. E-30 positive patients were significantly older and their disease course was more acute, with early admission to but also early discharge from hospital. E-30 positive patients showed a significantly higher rate of headache and meningism, and a lower rate of diarrhoea and clinically defined septicaemia when compared to the others. Regarding laboratory testing, E-30 positive patients presented with significantly elevated peripheral blood neutrophil counts when compared to patients with "Non E-30" or "Untyped" NPEV infection. In conclusion, E-30 meningitis in children shows a characteristic pattern of clinical features. To further characterise NPEV strains worldwide, continuous surveillance and typing of NPEV strains causing central nervous system disease is warranted.

A 58 year old man presented with one week of progressive right sided weakness and headache. He drank approximately 7 units of alcohol a week and had stopped smoking cigarettes 20 years ago (10 pack year history). He had no recent head injuries and took no medications or recreational drugs. He had no fever, weight loss, or night sweats and was fully alert. He had no signs of meningism or papilloedema and was afebrile with normal observations. Power in his right upper and lower limbs was of Medical Research Council grade 4/51 and he had …

Background The symptoms of meningitis which include fever, headache, photophobia and irritability along with abducens nerve palsy pose a diagnostic dilemma requiring urgent attention. Here we report how such a dilemma was methodically and sequentially resolved using anatomical knowledge supported by neuroimaging and the eventual diagnosis of Gradenigo syndrome was made. Case presentation A 6-year-old previously healthy boy from Sri Lanka presented with high grade fever, headache, photophobia and left eye pain for 10 days and diplopia for 2 days duration. Neurological examination was unremarkable except for left sided abducens nerve palsy. He had high inflammatory markers and white blood cell count. A tentative differential diagnosis of acute bacterial meningitis complicated by cerebral oedema, acute hydrocephalus or cerebral abscess was made. However, non-contrast CT brain, cerebrospinal fluid analysis and electroencephalogram were normal leading to a diagnostic dilemma. MRI brain with contrast performed 3 days later due to limited resources revealed left mastoiditis extending to petrous temporal bone confirming Gradenigo syndrome. Conclusion This case report highlights the importance of a thorough physical examination in children presenting with unrelated neurological symptoms and signs. Unilateral abducens nerve palsy raises the suspicion of increased intracranial pressure and neuroimaging is vital in diagnostic uncertainties. Gradenigo syndrome emphasises the importance of incorporating anatomical knowledge into clinical practice.

Objectives: Hantavirus infection and leptospirosis are infectious diseases transmitted by rodents. The clinical picture is nonspecific, often involving the kidneys but other organs can be affected too. Clinical and biochemical clues to make a difference between these two entities will be described.Methods: A retrospective analysis was performed on a database of patients presenting between January 2012 and September 2017 at the emergency department of the university hospital Leuven, Belgium. Patients were selected on the basis of a compatible clinical picture, biochemistry, and microbiological evidence. Presenting complaints and clinical examination were compared. Blood, taken at presentation, was used for hematological and biochemical analysis.Results: Sixteen patients with hantavirus infection and eight patients with leptospirosis were identified. All patients complained about general malaise and fever. Other frequent complaints were myalgia and a headache. Patients with leptospirosis often experienced photo- or sonophobia.Looking for neck stiffness and eye lesions might help to diagnose leptospirosis.Differences in biochemistry between viral and bacterial disease could be recognized; high C-reactive protein (CRP) and leukocytosis with left shift favor leptospirosis, elevated lactate dehydrogenase (LDH) favors viral infection. Abnormal liver function with raised total bilirubin is often seen in cases with leptospirosis.Conclusion: This study demonstrates some subtle clues that may help to differentiate between hantavirus infection and leptospirosis in patients presenting to a hospital in a nonendemic region of the world. Because of small number of patients, we could not identify significant clinical or biochemical tests. Serology remains the gold standard.

Pediatric pituitary adenomas are rare lesions. Incidence is reported between 1 and 10% of all childhood brain tumors and between 3 and 6% of all surgically treated adenomas. Although pituitary adenomas present with symptoms of hormone hypersecretion or neurological disruptions secondary to mass effect, they are almost constantly benign. Characteristics of patients may vary in different studies according to age, gender, size of adenoma, hormonal activity, and recurrence rates. Data on consecutive pediatric patients who were operated for pituitary adenoma with endoscopic endonasal transsphenoidal surgery (EETS) and transsphenoidal microsurgery (TMS) in the Department of Neurosurgery, Istanbul University Cerrahpasa Medical Faculty, Istanbul, Turkey, in the Neurosurgical Unit of the San Matteo Hospital, Pavia, Italy, and in the Division of Neurological Surgery Department of Biotechnology and Life Sciences, University of Insubria-Varese, ASST Sette Laghi, Ospedale di Circolo e Fondazione Macchi, Varese, Italy, between July 1997 and May 2018, were analyzed. Twenty-seven patients (11 males and 16 females), who were 18 years old or younger at the time of surgery, were included in the study. Medical records, images, and operative notes of patients were retrospectively reviewed. There were 16 females (59.3%) and 11 males (40.7%). Mean age was 15.3 ± 3.3 (4–18). Thirty-two surgical procedures were performed for 27 patients (6 children required second operation). Thirteen patients (48.14%) had Cushing’s disease (CD), 5 patients (18.5%) had growth hormone (GH)-secreting adenoma, 5 patients (18.5%) had prolactinoma, and 4 patients (14.8%) had non-functional adenoma. Twenty-two patients (81.4%) met remission criteria, and 5 patients (18.5%) did not meet remission criteria. Four patients met remission criteria after the second operation. Transsphenoidal approach affords effective release of mass effect and not only restoration but also perpetuation of normal endocrine functions in the majority of pediatric pituitary adenoma patients. Satisfactory results are reported with both EETS and TMS in the literature. Despite the technical difficulties in pediatric age, transsphenoidal resection of adenoma is still the mainstay treatment that provides cure in pediatric patients.

Introduction The spectrum of meningitis pathogens differs depending on the age of patients and the geographic region, amongst other. Although meningitis vaccination programs have led to the reduction of incidence rates, an imbalance between low- and high-income countries still exists. Methods In a hospital-based study in rural northern Tanzania, we consecutively recruited patients with confirmed meningitis and described their clinical and laboratory characteristics. Results A total of 136 patients with meningitis were included. Fever (85%), meningism (63%) and impairment of consciousness (33%) were the most frequent clinical symptoms/signs. Nearly 10% of all patients tested were positive for malaria. The majority of the patients with bacterial meningitis (39%), especially those under 5years of age, were confirmed to be infected with Haemophilus influenzae (26%), Streptococcus pneumoniae (19%) and Neisseria meningitidis (15%). Haemophilus influenzae represented the dominant causative organism in children under 2years of age. Conclusion Our study emphasizes the importance of recognizing warning symptoms like fever, meningism and impairment of consciousness, implementing laboratory tests to determine responsible pathogens and evaluating differential diagnoses in patients with meningitis in sub-Saharan Africa. It also shows that Haemophilus influenza meningitis is still an important cause for meningitis in the young, most probabaly due to lack of appropriate vaccination coverage.

Investigations were carried out in 24 patients in order to evaluate information value of the data of clinical, laboratory, neuroradiological methods of research and develop the diagnostic algorithm in case of cerebral venous thrombosis (CVT). The main group consisted of 11 patients (7 male, 4 female, average age 49,1±4,3) with CVT. The comparison group included 13 patients (6 male, 7 female; average age 68,1±9,5) with ischemic stroke (IS) of moderate severity. There were revealed changes in blood and cerebrospinal fluid (CSF) as form of leukocytosis of blood and moderately increased cell count with elevated protein in CSF and blood in case of CTV. The authors noted an elevated protein in CSF and blood and leukocytosis with predominant lymphopenia in blood and neurophilic predominance in CSF within the reference range of CSF in patient with ischemic stroke. The epileptic attacks, meningeal syndromes, headaches were more often among clinical syndromes at CTV than in case of ischemic stroke. The algorithm of neuroimaging research methods and modes of MRI were determined and allowed an effective diagnostics of damages of venous sinuses, superficial and deep cerebral veins in case of urgent hospitalization of patients. It was possible to suggest the venous pathology in 7 (63,6%) cases due to SKT (without contrast) and in case of application of MR venography (2D TOFmode), there were revealed 100% of cases.

Background Defined by an infection of the ventricular system of the brain, ventriculitis is usually known as a health-care associated infection. In contrast, primary pyogenic ventriculitis complicating community-acquired meningitis is uncommon, and mainly described in infants. Only seven cases that have occured in adults have been found in the international literature. Case presentation We report here a new case due to Neisseria meningitidis occurring in an 85 year-old-man. The comparison with previous reports allows to drawn several conclusions: (i) cases occurred in relatively old adults (median age: 65 years); (ii) Streptococcus pneumoniae, N. meningitiditis and Staphylococcus aureus are the leading responsible pathogens; (iii) atypical clinical presentation seems the rule in which meningism often lacks; (iv) in absence of clinical or biological specific parameters, modern brain imaging such as magnetic resonance imaging with gadolinium enhancement is of utmost importance for the diagnosis, leading to anticipate an increase of the diagnosis in the near future, thanks to easier access to such exploration; (v) death or serious sequelae commonly occurred; (vi) prolonged antibiotic courses (6 weeks to 3 months) have been used, without strong rational. In the given case, the patient presented with a lack of meningeal irritation signs. The diagnosis was made by MRI considering a lasting confused state. A four-week antibiotic regimen was successful, combining two weeks of intravenous cefotaxime followed by two weeks of oral levofloxacin much easier to administrate and allowing early rehabilitation. Conclusion Primary bacterial ventriculitis is a real diagnosis challenge. Larger indications of MRI for bacterial meningitis, particularly in cases with an atypical presentation or poor evolution would certainly increase the number of diagnosis.

Background Intracranial vasculopathy in adult patients with human-acquired immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is a rare but increasingly recognized disease entity. Objective We aimed to contribute to and summarize the adult literature describing patients with HIV/AIDS who have intracranial vasculopathy. Methods A retrospective review of adult patients with HIV/AIDS undergoing diagnostic cerebral angiography at our institution from 2007–2013 was performed. A literature review of relevant existing studies was performed. Results Five adult patients with HIV-related aneurysmal and occlusive vasculopathy were diagnosed and/or treated at our institution. A comprehensive review of the literature yielded data from 17 series describing 28 adult patients with HIV/AIDS and intracranial vasculopathy. Our review suggests that low CD4 count, motor weakness, and meningismus may be associated with the sequelae of intracranial vasculopathy/vasculitis in patients with HIV/AIDS. Conclusion Patients with HIV/AIDS who have aneurysmal and stenotic vascular disease may benefit from earlier surveillance with the onset of neurological symptoms. The roles of medical, open surgical, and endovascular therapy in this unique entity will be further defined as the pathological basis of the disease is better understood.

Background: Pseudomonas aeruginosa is a rare cause of meningitis and ventriculitis but is generally associated with significant morbidity and mortality. Aim: We sought to determine the epidemiology, risk factors and outcome of meningitis and ventriculitis due to P. aeruginosa at our institution in order to inform preventive strategies and treatment guidelines. Methods: Retrospective study of all patients with a positive cerebrospinal fluid (CSF) culture admitted to a tertiary care hospital over 18 years. Clinical details, demographic, microbiological and antibiotic data were obtained from laboratory and medical records. Results: Twenty-four episodes occurred in 21 patients over 18 years. Pyrexia (75%), fluctuating mental status (50%) and headache (41%) were the most frequent presenting symptoms. Nineteen of the 21 patients had previously undergone a neurosurgical procedure and seven had extra-ventricular devices in situ . Twelve (57%) patients had P. aeruginosa isolated from another site prior to their episode. Most (89%) CSF samples demonstrated a neutrophilia; the CSF protein, when measured, was raised in all cases. Gram-negative bacilli were visible on CSF microscopy in only three isolates. There were relatively low rates of resistance to most antimicrobials tested and combination treatment of intravenous with intrathecal antibiotics was often used. No patients died within 28 days. Conclusion: Pseudomonas aeruginosa meningitis and ventriculitis are predominantly nosocomial and related to prior neurosurgery. It can be difficult to diagnose as CSF Gram-film and meningism are insensitive markers. Appropriate empirical treatment, neurosurgical prophylaxis and surveillance can aid in managing this infection.

Hemophagocytic lymphohistiocytosis (HLH) is a rare multisystem disorder characterized by proliferation and diffuse infiltration multiple organs with histiocytes, including the central nervous system (CNS). Neurological manifestations of HLH have been recognized in different studies with children, but they remain relatively ill-defined in adults with HLH. From March 2008 to October 2014, 289 adult patients with HLH were admitted to our center. Clinical, radiological, and cerebral spinal fluid (CSF) data of the patients with CNS involvement were reviewed, and a retrospective study in our single-center was carried out. CNS involvement was observed in 29 patients (10%) either in their diagnosis process or during disease course. CNS symptoms included disturbance of consciousness, cranial nerve palsies, seizures, headache, limb paralysis, irritability, meningism, and memory loss. CSF analysis was conducted in 17 patients (59%). Among them, 11 patients (65%) were reported as having abnormal CSF. Neuroradiological studies were performed in 25 patients (86%). Among the 13 cases that underwent CT scan, one patient hemorrhaged. Single or multiple hypodense foci were detected in the other 2 patients. Magnetic resonance imaging (MRI) abnormalities were found in 15 patients, including focal lesions in cortical and adjacent subcortical regions with or without variable nodular or ring contrast-enhancement, multiple lesions in white matter, diffuse white matter signal changes, and meningeal enhancement. Basal ganglia, cerebellum, and brainstem lesions were also observed. CNS involvement could also be found in adult patients with HLH, but not as frequent as it was in children. The clinical manifestations could be diversified. By carrying out rigorous CNS examinations, an early diagnosis could be made and it was of the utmost importance for the prevention of further lesions.

Headache after aneurysmal subarachnoid hemorrhage (SAH) is very common and is often described as the “worst headache imaginable.” SAH-associated headache can persist for days to weeks and is traditionally treated with narcotics. However, narcotics can have significant adverse effects. We hypothesize that gabapentin (GBP), a non-narcotic neuropathic pain medication, would be safe and tolerable and would reduce narcotic requirements after SAH. We retrospectively reviewed the clinical, radiographic, and laboratory data of SAH patients at the neuroscience intensive care unit at Mayo Clinic in Jacksonville, Florida, from January 2011 through February 2013. Headache intensity was quantified by a visual analog scale score. Total opioid use per day was tabulated using an intravenous morphine equivalents scale. Cerebrospinal fluid was also reviewed when available. There were 53 SAH patients who were treated with GBP along with other analgesics for headache. Among these SAH patients, 34 (64 %) were women, with a mean age of 54 years (SD 12.3). Severe headache was observed in all SAH patients. GBP dosing was rapidly escalated within days of SAH up to a median of 1,200 mg/day, with a range of 300 mg three times a day to 900 mg three times a day. Approximately 6 % of patients treated with GBP had nausea (95 % CI 1–16 %), and only one patient (1.8 %) had to discontinue GBP. GBP appears to be relatively safe and tolerable in SAH patients with headache and may be a useful narcotic-sparing agent to prevent narcotics-associated complications, such as gastrointestinal immobility, ileus, and constipation.

Background Sporadic hemiplegic migraine (SHM) is defined as migraine attacks associated with some degree of motor weakness during the aura phase and where no first-degree relative has identical attacks. SHM has a wide inter- and intraindividual clinical spectrum and, in case of prolonged aura symptoms and disturbed consciousness, can mimic several other acute neurological diseases. Case In 1996, during his wedding night, a 28-year-old man developed left face, arm and leg weakness, nausea and a throbbing headache. Neurological examination on presentation revealed stupor, fever, meningism and left hemiplegia. There were no abnormalities on emergency magnetic resonance. Lumbar puncture showed mild lymphocytic pleocytosis and slightly elevated protein. He received symptomatic treatment. Subsequent genetic analysis revealed the T666M mutation in the CACNA1A gene of chromosome 19. He was diagnosed with SHM. In 2005, at the end of another episode of hemiplegic migraine (HM), he for the first time developed an episode of paranoid psychosis with anxiety and visual hallucinations. The psychiatric symptoms resolved within a week. Discussion All perfusion SPECT and transcranial Doppler studies performed in the first days of HM attacks were consistent with hyperemia of the hemisphere contralateral to the neurological signs. FDG-PET/CT in January 2013 revealed a diffusely reduced glucose metabolism of the supratentorial cortex and marked asymmetric hypometabolism of the left cerebellum. The finding of progressive cortical metabolic dysfunction over years appears as a new finding. Glucose hypometabolism may indicate primary neuronal dysfunction as the cause of the prolonged deficits.

Isolated fourth ventricle is not uncommon in complex posthemorrhagic or postinfectious hydrocephalus. When the condition is symptomatic, the current surgical treatment is endoscopic aqueductoplasty, followed by endoscope-assisted placement of a catheter in the fourth ventricle. The authors suggest a very simple method of steering the tip of standard ventricular catheters by using materials commonly available in all operating rooms. The main advantage of this method is that it permits less invasive transaqueductal drainage of trapped fourth ventricles, especially in cases of narrow third ventricle, because the scope and catheter are introduced in sequence and not in a double-barreled fashion. Two illustrative cases are reported.

The objective of this study is to describe the characteristics of patients with pachymeningitis (PM) in granulomatosis with polyangiitis (GPA) from Latin America, including three young patients. This is a retrospective case series. Patients were classified according to the ACR criteria, the 2012 Chapel Hill Consensus Conference Nomenclature and the EMA algorithm. Demographic, clinical, serological, and neuroimaging characteristics are described. Thirteen patients (nine females, four males) were identified. Mean age ± SD of PM diagnosis was 35.5 ± 20.4 years (median 48, range 8–71 years). Mean time ± SD between GPA first symptom and PM diagnosis was 59.8 ± 70.1 months (median 48, range 2–252 months). An important difference between children and adults was the median time elapsed between first GPA symptoms and PM diagnosis (range 2–4 months vs 5–252 months, respectively). Chronic headache was present in all, followed by intracranial hypertension (n = 5), single cranial nerve palsy and orbital mass (n = 4), seizures (n = 3), cavernous sinus syndrome and multiple cranial nerve palsies (n = 2), and meningism and cerebellar syndrome (n = 1 each). At time of PM diagnosis, mean BVAS/WG (Birmingham Vasculitis Activity Score for Wegener’s granulomatosis) was 4 ± 2.4 and mean VDI of 2 ± 1.6, mostly due to ENT damage. Gadolinium-enhanced brain MRI showed dural thickening in 12 patients and leptomeningeal enhancement in one. All received a combination of glucocorticoids plus immunosuppressants, rituximab being used favourably in one refractory case. Improvement was observed in 12 patients. Chronic headache should lead to suspect PM. PM predominates in localised GPA. Children may present it earlier in the disease course than adults. Treatment is non-standardised and remains difficult.

An 88-year-old man with Parkinson's disease was admitted to the hospital with chronic epididymo-orchitis. During his admission, he had a fall and suffered a head injury, with no loss of consciousness, no urinary incontinence and no tongue biting. Shortly after, he developed a generalised headache with no other features of raised intracranial pressure. On examination, he was found to have nuchal rigidity but no focal neurological deficits. He was afebrile with stable vital signs and neurological observations. Inflammatory markers and electrolytes were normal. Axial CT showed multiple areas of low …

A 26 year old otherwise well man with no medical history of note attended his general practice with a five day history of severe right ear pain and scanty ear discharge. He had returned from holiday one week earlier, where he had been swimming. He had no headache, fever, or systemic upset. Clinical examination identified oedema and discharge at the right external auditory meatus but an otherwise normal pinna. Palpation of the right tragus caused sudden onset intense pain, and otoscopy showed oedema of the external auditory canal, with a small amount of discharge obstructing visualisation of the tympanic membrane. He had no post-auricular swelling, erythema, tenderness suggestive of mastoiditis, or signs of meningism. His observations were within normal limits. 1. What is the most likely diagnosis? 2. How would you manage this patient? 3. When would you refer him to secondary care? 4. What advice would you give him? ### 1. What is the most likely diagnosis? #### Short answer Acute otitis externa. #### Discussion The diagnosis is acute right otitis externa, an acute inflammatory condition of the skin of the external auditory canal, generally secondary to bacterial infection.1 This condition is often seen in primary care, with a reported prevalence of 1% within a 12 month period.1 2 Common symptoms associated with this condition include otalgia, otorrhoea, pruritus, and hearing loss.1-3 In uncomplicated disease, clinical examination often shows oedema of the external auditory canal, with or without erythema and discharge, and a normal and intact tympanic membrane.1 3 A key clinical sign is tenderness over the …

Spontaneous pituitary apoplexy in the absence of a known pre-existing pituitary adenoma is a very rare cause of sudden onset headache, but can be potentially sight- and life-threatening. We describe a case of a 37-year-old man who presented to the Emergency Department with a severe headache, associated nausea, vomiting and features of meningism. A suspected clinical diagnosis of subarachnoid haemorrhage led to an urgent computed tomography scan of the head demonstrating a large pituitary macroadenoma. A diagnosis of pituitary apoplexy was suspected and he was transferred as an emergency case to the regional tertiary hospital for management. A further urgent magnetic resonance imaging scan showed haemorrhage into the pituitary adenoma, confirming pituitary apoplexy. We discuss this clinical condition and the new UK national guidelines which have recently been published to improve clinical assessment, investigation and management of patients with suspected pituitary apoplexy.

Objective To evaluate the discriminative ability of the Manchester triage system (MTS) to identify serious bacterial infections (SBIs) in children with fever in the emergency department (ED) and to study the association between predictors of SBI and discriminators of MTS urgency of care. Methods This prospective observational study included 1255 children with fever (1 month–16 years) attending the ED of the Erasmus MC – Sophia Children9s Hospital, Rotterdam, The Netherlands in 2008–9. Triage urgency was determined with the MTS (urgency (U) level 1–5). The relationship between triage urgency and SBI was assessed with multivariable logistic regression, including effects of age, sex and temperature. Discriminative ability was assessed by receiver operating characteristic curve analysis. Results SBI prevalence was 11% (n=131, 95% CI 9% to 12%). The discriminative value of the MTS for predicting SBI was 0.57 (95% CI 0.52 to 0.62), and the MTS did not contribute to a model including age, sex and temperature. The sensitivity of the MTS (U1–2 vs U3–5) to detect SBI was 0.42 (95% CI 0.33 to 0.51) and specificity was 0.69 (95% CI 0.66 to 0.72). MTS high urgency discriminators include several known predictors of SBI, such as fever, work of breathing, meningism and oxygen saturation, but apply to non-SBI children as well. Conclusion The MTS has poor discriminative ability to predict the presence of SBIs in children presenting with fever to the paediatric ED. Important predictors of SBI are represented within the MTS, but are used in a different way to classify urgency.

Clinical features of echovirus 6 and 9 infections in children have not been comprehensively evaluated, particularly for sporadic cases.To describe the clinical features of children with echovirus 6 or 9 infections.From 2000 to 2008, 199 children with culture-proven echovirus 6 or 9 infections identified in a university-affiliated hospital were included. Data extracted from 174 inpatients were further analyzed.Age ranged from 4 days to 15 years with a mean of 4.7 years. 123 (62%) were male. The disease spectrums were similar for echovirus 6 (n=100) and 9 (n=74) infections, with aseptic meningitis (49% and 51%, respectively) being the most common syndrome, followed by meningismus, upper respiratory tract infection, pneumonia, and herpangina. All 174 inpatients had fever but the duration of fever was significantly longer in patient with echovirus 9 infection than those with echovirus 6 infections (6.0 days vs. 3.8 days, p0.001). The rate of leukocytosis (leukocyte count15,000/μL) were significantly higher in patients with echovirus 6 infections than those with echovirus 9 infection (p0.001). One neonate with echovirus 6 infection died from hepatic necrosis with coagulopathy, and one infant with echovirus 6 infection and one child with echovirus 9 infection died from brain involvement. Two children had long-term sequelae of seizure disorder. The remaining 169 children (97%) recovered uneventfully.For children with echovirus 6 or 9 infections requiring hospitalization, aseptic meningitis was the most common manifestation and fatal outcome or long-term sequel, though rare, might occur.

Objective: To evaluate the prognostic usefulness of cerebrospinal fluid (CSF) lactate in postoperative bacterial meningitis (POBM) and to establish the optimal CSF lactate cut-off values in our population to identify POBM in neurosurgical patients. Patients and Methods: A prospective study of postoperative neurosurgical patients with presumed and established bacterial meningitis in the Department of Neurosurgery, NIMS, Hyderabad, India, from September 2012 to December 2014. The diagnostic and prognostic values of CSF lactate have been evaluated and compared with other well-established CSF markers. All the patients who have undergone intradural cranial surgery with features of meningism have been included. Results: The study included 37 patients. The CSF value of the first lumbar puncture (LP) was taken to evaluate the diagnostic value of CSF lactate. Twenty three corresponded to Group A, and 14 to Group B. The mean CSF lactate in Group A was 5.94 ± 2.36, and in Group B 4.60 ± 2.31. Subsequent LPs were performed and CSF analyzed to evaluate the prognostic value of CSF lactate. The CSF markers like neutrophil count (P = 0.003), CSF/blood glucose ratio (P = 0.012), CSF lactate (P = 0.024), lymphocyte count (P = 0.046), leukocyte count (P = 0.047) have shown their prognostic value in a descending order. CSF markers like the presence of red blood cells (P = 0.540) and proteins (P = 0.757) did not show prognostic significance. The decline in CSF lactate (content and concentration) after initiation of antibiotics correlated with subsidence of fever (P = 0.0001), decrease in neck rigidity (P = 0.022) and improvement in sensorium. They were also correlated improvement in CSF/blood glucose ratio and CSF white blood cell counts. Conclusions: In our study, CSF lactate was noted to have a dependable prognostic value in POBM. As routine CSF markers can be ambiguous in POBM, CSF lactate can be considered a better alternative for both establishing the diagnosis and prognostication.

Background Acute meningoencephalitis (ME) from varicella zoster virus (VZV) reactivation is a rare and serious complication of herpes zoster (HZ). Objectives and methods As early diagnostic detection is mandatory to prevent long-term sequelae, any clinical indication is helpful to identify patients that are at higher risk of the development of VZV-ME. In order to find such risk factors, the clinical data of 38 patients consecutively hospitalized for the treatment of HZ over a 1-year period were analyzed. Results Four of the 38 patients with HZ developed ME. Of these, three had involvement of the trigeminal nerve branch, one including an ophthalmic affection, and one presented with disseminated HZ. All were women with an average age of 83.5 years, in comparison with patients with HZ but without ME who had an average age of 69.3 years and a female preponderance of 60%. The first clinical signs of ME were rapidly progressing somnolence and meningism. Patients with HZ-ME were treated with intravenous acyclovir, oral glucocorticosteroids, and antiseizure therapy, and recovered almost completely without major residual symptoms. Conclusion Progression of HZ to ME seems to occur more often than normally believed. Female patients above 80 years of age with either ophthalmic involvement or disseminated HZ are at a potentially high risk of the development of ME. The general recommendation of starting oral glucocorticosteroids from day 1 of antiviral treatment in older patients must be questioned, as it may stimulate VZV replication and dissemination.

Liquor:serum quotients of IgG and albumin in patients with meningism, meningitis and multiple sclerosis have been studied. Abnormal quotients indicative of disturbed blood-brain barrier function and/or intrathecal IgG synthesis were found in various proportions of all 3 groups of patients. In some patients with aseptic meningitis and meningism, the abnormal quotients were comparable with those found in patients with multiple sclerosis. The reason for this is unknown. An unspecific reaction to febrile illness may be involved. As a consequence, the findings of abnormal liquor:serum quotients of IgG and albumin should be evaluated with great caution in patients with recent or present febrile illness.

Background/Objective: Pseudomeningocele is most commonly the result of a rent in the meninges during spine surgery. Noniatrogenic causes exist but are rare. Pseudomeningoceles may heal spontaneously, but they may also slowly enlarge. They rarely present as a mass within the abdomen. The objective of this study was to present the first case report of hydronephrosis secondary to lumbar pseudomeningocele.Design: Single case report and literature review.Methods: Single case report.Results: This man had undergone extensive lumbar spine surgery for pain and spondylolisthesis. He subsequently developed a pseudomeningocele that caused hydronephrosis of the left kidney. He was treated with surgical intervention and had resolution of his hydronephrosis and his flank and groin pain. He also had improvement of his back pain.Conclusions: This report shows an unusual cause of hydronephrosis—a pseudomeningocele presenting as an abdominal mass that compressed the ureter.

The incidence of tuberculosis (TB) is increasing in both developing and developed worlds, and children, in particular, represent a high-risk group for acquiring the disease. TB of the central nervous system is the most severe, life-threatening form of TB in infants and children. Approximately 10% of all patients with TB have central nervous system involvement.We have selected four pediatric cases of unusual spinal TB that presented to our institution during the last 5 years. These include TB arachnoiditis, intramedullary spinal cord tuberculoma, TB spondylitis of the odontoid peg, and one child with tuberculous extradural abscess.TB may involve the intramedullary, extramedullary intrathecal compartment, or the extrathecal vertebral compartment in the form of an arachnoiditis, abscess, and spondylitis, respectively, often with unusual imaging presentations.

A 43-year-old man presented in April 2004 with a six-week history of a runny nose and a “cold”, and for three weeks he had also been feeling generally unwell with mild vertigo, tinnitus and unsteadiness; the latter symptoms had worsened over a week but had not progressed for two weeks. On examination his blood pressure was 120/70, he was afebrile, and there was no meningism. He was orientated, and told his own story. Fundoscopy was normal. There was fine gaze-evoked bilateral horizontal nystagmus and obvious ataxia of his upper and lower limbs and gait. General medical examination, including the testicles and skin, was normal. He was extensively investigated and the following tests were normal or negative: full blood count, urea and electrolytes, liver function (alkaline phosphatase 52 IU/l (30–115), aspartate transaminase 31 IU/l (5–45)), thyroid function, ANCA, anti-dsDNA antibodies, C-reactive protein, vitamin B12 and folate, calcium, chest x ray, 12-lead ECG, MRI head. The cerebrospinal fluid (CSF) contained 24 red blood cells and 16 white blood cells/cm3. CSF cytology showed a moderate number of reactive lymphocytes, the significance of which was difficult to interpret in the presence of red blood cells. The CSF protein was 0.55 g/l and the glucose 3.7 mmol/l. Oligoclonal bands were present, unmatched in serum. No changes in viral antibody titres in blood were detected and syphilis serology was negative. CSF PCR for herpes simplex virus type 1 and 2, and herpes zoster was negative. Serum alphafeto protein was 11 kU/l (3–8) and serum human chorionic gonadotrophin

The objective of this study was to investigate the antioxidant/oxidant status of serum and cerebrospinal fluid in children with meningismus and acute bacterial meningitis. Twenty-three children (age range, 0.75 to 9 years) with fever and meningeal signs that required analysis of the cerebrospinal fluid, but no cytologic or biochemical evidence of meningitis in their serum and cerebrospinal fluid, constituted the meningismus group. Thirty-one children (age range, 0.5 to 10 years) with acute bacterial meningitis constituted the meningitis group. Twenty-nine healthy children (age range, 0.5 to 11 years) were recruited as control subjects. Antioxidant status (ascorbic acid, albumin, thiol, uric acid, total bilirubin, total antioxidant capacity, catalase and ceruloplasmin concentrations) and oxidant status (lipid hydroperoxide and total oxidant status) were measured. The serum antioxidant status was lower, and oxidant status levels higher in both meningitis and meningismus subjects than in the control children (P < 0.001). Cerebrospinal fluid oxidant status was lower in the meningitis group than in the meningismus group (P < 0.05). These results indicate that serum antioxidant status was lower, and serum oxidant status was higher in children in the meningismus and meningitis groups, whereas cerebrospinal fluid oxidant status was higher in the meningismus group than in the meningitis group.

Pediatric cases of infratentorial subdural empyema (SDE) are both rare and associated with high rates of morbidity and mortality. The goal of this study was to report patient characteristics, treatment, and outcome in an exclusively pediatric series of SDE cases.A series of 14 pediatric cases of infratentorial SDE was retrospectively analyzed. All patients were treated between 1994 and 2004. Sixty-four percent of the patients were boys; the majority of cases occurred during the summer months. Clinical features included headache, fever, vomiting, meningism, and otorrhea. Cerebellar signs were found only in 21% of patients. In 85.7% of the cases, the patients presented with a depressed level of consciousness (Glasgow Coma Scale Scores 11-15). In 79.6%, pus collection was seen over the cerebellar convexity; interhemispheric and tentorial collections were also observed in some cases. Hydrocephalus was present in 92.9% of patients. Five patients required external ventricular drainage during surgery or postoperatively. Shunt placement was required in 21% of cases. All patients were treated with antibiotic therapy and surgery (bur holes in 21% of the cases, craniectomy in 79%). Pus cultures demonstrated microbial infection in 71.4%, and polymicrobial infection in 21%. Four patients required repeated surgery for reaccumulation of pus. Minor postoperative complications developed in three patients. All 14 patients survived. At follow up, the Glasgow Outcome Scale scores were 4 or 5 in all cases.Early diagnosis and prompt surgical treatment are crucial in cases of SDE. With appropriate surgery, antibiotic therapy, and management of hydrocephalus, good outcome can be expected.

Objective: Although meningism manifesting acute headache has been observed to be associated with common viral and bacterial infections, its definition and pathogenesis have not been clarified. Clinical findings and cerebrospinal fluid (CSF) cytokines in adult patients with meningism were investigated and compared with those in viral meningitis. Patients and Methods: Among the adult inpatients in our hospital from 1997 to 2004, 5 with meningism and 17 with viral meningitis were identified according to the criteria described in this study, and their clinical data were analyzed. In the CSF samples of the 5 patients with meningism and the 17 with viral meningitis, the concentrations of interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), interleukin-2 (IL-2), IL-4, IL-6, and IL-10 were determined using a cytometric bead array. Results: The five patients with meningism all showed fever and meningeal signs such as severe headache and nuchal stiffness without CSF pleocytosis (

To describe adverse events occurring after mass vaccination with conjugate and nonconjugate vaccines and to assess the incidence of serious adverse effects. A mass immunisation campaign against meningococcal C disease was conducted in two French administrative areas, Landes and Pyrenees atlantiques, for 2 months (from October to December 2002). Adverse events were reported by families and physicians by means of a specific reporting form returned to the pharmacovigilance centre 15 days after vaccination. The target population was 260,630 individuals aged between 2 months and 24 years. About 179,000 children and young adults were vaccinated. A total of 92,711 report forms were received by the pharmacovigilance centre, and 12,695 subjects presented at least one adverse event. The most frequently involved systems/disorders were application site disorders (48.4%), whole-body general disorders (21.8%), central and peripheral nervous system disorders (14.6%), and gastrointestinal system disorders (4.7%). Most of these adverse events were transient and not serious. There were 13 serious adverse events: one each of syncope, fever, headache with fever, neuralgia, serum sickness, arthritis, purpura, facial paralysis, multiple sclerosis, lipoma, and meningism, and two cases of bronchospasm. No significant difference was found in rates of adverse event reports between both vaccines. The estimated incidence of serious adverse effect reports was 7 per 100,000. This campaign was the second immunisation campaign undertaken in France involving both physicians and families as reporters. Although unlabeled adverse effects were identified during this campaign, they were mostly nonserious and have been known to occur with other vaccines.

Before routine infant pneumococcal immunisation and improved access to neuroimaging, around 25% of children with pneumococcal meningitis (PM) suffered ischaemic stroke (IS).1 ,2 In a population-based retrospective audit (UHS ZAUD2053), we investigated the postimmunisation prevalence of stroke/cerebrovascular disease (CVD), and compared features of children with and without IS/CVD. We included all cases of PM in children 5 white cells in the CSF and/or signs of meningism and/or focal neurology and/or meningeal enhancement on CT with contrast. Stroke and/or CVD were identified on CT …

The introduction of MRI has shown that the acute, recurrent (R), and multiphasic (M) forms of disseminated encephalomyelitis (DEM) are more common than suspected in adults, and that their MR images are sufficiently characteristic in most instances to make differentiation from multiple sclerosis (MS) possible. In addition, a number of clinical features of DEM are rarely seen in MS: fever, malaise, nausea, vomiting, positional vertigo, convulsions, aphasia, meningism, bilateral optic neuritis, and CSF leukocytosis and elevated protein. CSF oligoclonal bands are usually absent. It is remarkable that confusion between R- and MDEM and MS persists despite the numerous published reports on recurrent DEM dating back 70 years, many illustrating the characteristic MRIs. There are many case reports of DEM erroneously diagnosed as MS, Schilder's, Marburg's, Devic's, and Balo's disease, and, in particular brain tumors. It is probable that acute DEM is occasionally mistaken for a clinically isolated symptom of MS. Possible mechanisms for recurrence include localization at the site of a previous injury to the nervous system, or by the phenomenon of molecular mimicry. The importance of differentiating R- and MDEM from MS is greater today due to the recommendation that immunodulatory treatment be initiated in patients with a clinically isolated syndrome, or when the occurrence of a second clinical episode establishes the diagnosis of MS.

In a previous study we devised a diagnostic decision rule to improve management of children with meningeal signs, suspected of having bacterial meningitis. The decision rule aimed to guide decisions on (1) whether a lumbar puncture is necessary in children with meningeal signs, and (2) which children need hospitalisation and empirical antibiotic treatment for bacterial meningitis. In this study we assessed the validity of this rule in an external population of four (paediatric) hospitals in The Netherlands. The decision rule included two scoring algorithms using symptoms, signs and quickly available blood and cerebrospinal fluid (CSF) laboratory tests. To evaluate the discriminative value of both algorithms, the absolute numbers of correctly diagnosed patients and the area under the receiver operator characteristic curve were estimated, and compared with the results from the original population (n = 360). In a 18 month period, we included 226 children, median age 2.2 years, who visited the emergency department with meningeal signs. Bacterial meningitis was present in 25 (11%). Using the scoring algorithms patients could be categorised in groups of increasing risk of bacterial meningitis. The discriminative values of the clinical and CSF algorithm in this new population were similar to those in the original population. In the total population of 586 children with meningeal signs, the rule selected 205 children (35%) who did not need a lumbar puncture and 366 children who did not need empirical treatment (62%). In conclusion, this diagnostic rule performed well in a new population of children with meningeal signs. This diagnostic decision rule is a valuable tool for the clinician when deciding to treat these children for bacterial meningitis and thus improving their management.

A previously healthy 31-year-old male presented with acute eft facial weakness and horizontal binocular diplopia on looking o the left. Three weeks prior to that, he had fever, myalgia and a eneralized papulovesicular rash 10 days following exposure to his -month-old son who had similar skin lesions. His constitutional ymptoms and rash resolved completely over 2 weeks. Neuroogical examination revealed complete left facial paralysis with ncomplete eye closure and abduction failure of the left eye with onsequent horizontal diplopia. The reminder of the cranial nerve xamination was normal. There were no skin rashes, meningism r long tract signs. These findings were consistent with acute left ower motor neuron facial and left abducens neuropathies. Craial magnetic resonance imaging (MRI) did not detect abnormal arenchymal, leptomeningeal or ependymal lesions or enhanceent. Cerebrospinal fluid (CSF) examination revealed a white cell ount of 8/mm3 (99% lymphocytes, 1% monocytes) and protein of .56 g/L.

A previously well 12-year-old boy presented with a 2-week history of headache, nausea, vomiting and left-sided weakness. He subsequently developed meningism, right abducens nerve palsy, persistent papilloedema and reduced visual acuity in association with a bilateral macular star, consistent with neuroretinitis. Cerebrospinal fluid (CSF) examination indicated chronic meningitis and serological testing confirmed recent Mycoplasma pneumoniae infection, although PCR in CSF was negative. He was treated for aseptic meningitis with ceftriaxone, aciclovir, azithromycin and acetazolamide for intracranial hypertension, with gradual improvement in clinical condition and visual acuity over several weeks. This is the first report of M. pneumoniae chronic meningitis further complicated with bilateral neuroretinitis and intracranial hypertension. Evidence of central nervous system inflammation in the absence of direct infection suggests an immune-mediated pathophysiology. Although the use of macrolides with antibiotic and immunomodulatory activity might be beneficial, it was not possible to ascertain whether it influenced clinical recovery in this case.

Meningitis still accounts for many deaths in children especially during epidemics in countries within the African meningitis belt. Between February and May 2012, the Gambia witnessed an outbreak of meningitis in two of its six regions. This study presents a clinical perspective of this outbreak in central river region of the Gambia. It evaluated the outbreak pattern, clinical features, and mortality among suspected cases that presented to the hospital during the outbreak.This is a prospective observational study of suspected cases of meningitis that presented to the pediatric ward of the Bansang Hospital during the outbreak period. Confirmed cases of meningitis were consecutively enrolled, and those with negative blood cultures presenting during the same period were employed as controls.Two hundred and four suspected cases of meningitis presented to the pediatric ward during the outbreak. Ninety were confirmed as meningitis cases. The W135 strain of Neisseria meningitidis was responsible for 89 (98.9%) of meningitis cases seen with an incidence rate of 74.9/100,000 in children (0-14 years) and in-hospital case fatality rate of 7.9%. Highest attack rate was among the 12-49 months age group. Clinical features such as meningeal signs (neck stiffness), conjunctivitis, and joint swelling were seen more in cases than controls. Contact history with relatives, who had fever in previous 2 weeks prior to illness was significantly seen more in cases. Adjusted regression analysis showed 7.5 more likelihood of infection with positive contact history (odds ratio [OR]: 7.2 confidence interval [CI]: [3.39-15.73]). There was no significant difference in death outcome between cases and controls (OR: 0.78 CI: [0.29-2.13]). The double peak wave-like pattern of the epidemic curve noted during this outbreak suggests a disseminated outbreak originating from an index case with propagated spread.There is need for more effective surveillance and incorporation of vaccine against meningitis into the expanded program on immunization schedule of the Gambia and other countries within the meningitic epidemic belt.

The diagnosis of acute bacterial meningitis (ABM) is challenging in resource-limited settings where cerebral malaria and viral encephalitis are also common.To assess the accuracy of an initial clinical diagnosis of ABM in a malaria-endemic area of Papua New Guinea (PNG), a retrospective chart review of hospitalized children aged 2 months to 10 years was conducted.Of the 481 eligible children, 240 had an initial clinical diagnosis of ABM that was confirmed independently by trained research staff under standardized conditions, with laboratory support in only 84 (17.5%; 84/481). When compared with the final laboratory-confirmed diagnosis, an initial diagnosis of ABM had a sensitivity, specificity, positive predictive value and negative predictive value of 76% (95% CI 66-85%), 56% (95% CI 51-61%), 27% (95% CI 21-33) and 92% (95% CI 87-95%), respectively. There was discordance between initial and final diagnosis of ABM in 196 children; 176 initially considered to have ABM had an alternative diagnosis, while 20 without an initial diagnosis of ABM were confirmed to have ABM.These data show that initial misdiagnosis of ABM is common in a malaria-endemic area of PNG. A diagnostic algorithm using standardized assessment for meningeal irritation, coma and malaria parasitological testing needs further evaluation in this setting.

Although signs of meningeal irritation are highly indicative of meningitis, they are not pathognomonic. In this study, we described the final diagnoses in children with signs of meningeal irritation, and we assessed the frequency of bacterial meningitis related to specific signs of meningeal irritation.Information was collected from records of 326 patients (aged 1 month to 15 years) who visited the emergency department of the Sophia Children's Hospital between 1988 and 1998 with signs of meningeal irritation, assessed by either the general practitioner or the pediatrician.Bacterial meningitis was diagnosed in 99 patients (30%), viral or aseptic meningitis in 43 (13%). Other diagnoses were pneumonia (8%), other serious bacterial infections (2%), and upper respiratory tract infections or other self-limiting diseases (46 %). Presence of one of the signs of meningeal irritation assessed by the pediatrician was related to bacterial meningitis in 39%. Specific tests eliciting meningeal irritation, such as Brudzinski's and Kernig's signs, were not related to a higher frequency of bacterial meningitis than neck stiffness and the tripod phenomenon. In childrenor =1 year, bacterial meningitis is more frequently related to presence of irritability and a bulging fontanel.Bacterial meningitis is present in 30% of children with signs of meningeal irritation. Presence of meningeal irritation as assessed by the pediatrician is related to bacterial meningitis in 39%. A better prediction of bacterial meningitis was not achieved by using more specific tests for signs of meningeal irritation.
