Meningitis, Status epilepticus

The development of seizures in epilepsy syndromes associated with malformations of cortical development (MCDs) has traditionally been attributed to intrinsic cortical alterations resulting from abnormal network excitability. However, recent analyses at single-cell resolution of human brain samples from MCD patients have indicated the possible involvement of adaptive immunity in the pathogenesis of these disorders. By exploiting the MethylAzoxyMethanol (MAM)/pilocarpine (MP) rat model of drug-resistant epilepsy associated with MCD, we show here that the occurrence of status epilepticus and subsequent spontaneous recurrent seizures in the malformed, but not in the normal brain, are associated with the outbreak of a destructive autoimmune response with encephalitis-like features, involving components of both cell-mediated and humoral immune responses...

Temperature control in severe acute brain injury (SABI) is a key component of acute management. This manuscript delves into the complex role of temperature management in SABI, encompassing conditions like traumatic brain injury (TBI), acute ischemic stroke (AIS), intracerebral hemorrhage (ICH), aneurysmal subarachnoid hemorrhage (aSAH), and hypoxemic/ischemic brain injury following cardiac arrest. Fever is a common complication in SABI and is linked to worse neurological outcomes due to increased inflammatory responses and intracranial pressure (ICP)...

BACKGROUND: Pediatric coronavirus disease 2019 infection usually presents with respiratory and gastrointestinal symptoms. In this report we present fulminant meningitis as the main presentation of coronavirus disease 2019 without major signs and symptoms of other organs' involvement in 3 infants. CASES: The first case was a 4 months Iranian male infant with fulminant meningitis as the main presentation of coronavirus disease 2019 without other organ involvement...

BACKGROUND: Although controversial, endoscopic third ventriculostomy (ETV) in the management of Myelomeningocele and Chiari type II malformation-related hydrocephalous is gaining wider popularity and use. With variable success rates, it can be proposed as a first or second option after shunt malfunction. ETV in post-infectious hydrocephalus may also be considered as an alternative to shunting. With reported success rates of 50-60%, failure is attributed to anatomical reasons and/or to pathological subarachnoid space scarring that may result from infectious processes...

OBJECTIVE: To investigate the short-term benefits and adverse effects of ketamine in the treatment of pediatric and adolescent super-refractory status epilepticus (SRSE), with a focus on the inflammatory etiology. METHODS: This retrospective observational cohort study included a consecutive series of 18 pediatric to adolescent patients with SRSE admitted between 2008 and 2023 and treated with ketamine. Seizure frequency per hour before and after ketamine administration and response rate were calculated...

In Jeju Island, South Korea, a patient who consumed raw pig products had subdural empyema, which led to meningitis, sepsis, and status epilepticus. We identified Streptococcus suis from blood and the subdural empyema. This case illustrates the importance of considering dietary habits in similar clinical assessments to prevent misdiagnosis.

OBJECTIVE: To assess the incidence of seizures and the factors contributing to poor outcomes in patients with tuberculous meningitis (TBM). METHODS: In this prospective observational study, 129 patients with TBM were enrolled at the Department of Neurology, King George's Medical University, Uttar Pradesh, India, from April 2021 to April 2023. Detailed clinical history, neurological examinations, baseline laboratory tests, contrast-enhanced Magnetic resonance imaging (MRI) and electroencephalography (EEG) were obtained for all patients...

To analyze clinical characteristics and anesthesia-related factors influencing central fever during cranial neurosurgery. 31 central fever cases (observation) and 120 controls (no fever) underwent detailed investigation. Anaesthesia-related variables were analyzed using logistic regression. Observation group exhibited significantly elevated indicators-CSF white blood cells, protein, CRP, severe EEG abnormalities, abnormal imaging, positive meningeal signs, seizures, consciousness disorders, and status epilepticus (P < ...

The "white cerebellum sign" is a striking neuroradiological finding, resulting from diffuse hypodense brain lesions in both cerebral hemispheres while sparing the cerebellum. This indicates widespread ischemic damage or expanded cerebral edema associated with the loss of white-gray matter differentiation. It is commonly reported in pediatric cases with severe neurological conditions, usually resulting in a poor prognosis. We present a case of a three-month-old female infant who was managed for confirmed acute bacterial meningitis complicated by status epilepticus, where the Computed tomography scan (CT scan) showed the "white cerebellum sign" in relation to diffuse cerebral hypoxic-ischemic lesions...

In this case, a 77-year-old woman presented with generalized weakness, difficulty ambulating, lethargy, loss of appetite, and headaches after a mechanical fall. This case discusses the management of acute neurologic emergencies such as subdural hematoma, status epilepticus, and bacterial meningitis. Potential etiologies for stroke and CNS infection are highlighted. Readers are led through the diagnostic approach to a patient presenting with a complex array of neurologic symptoms causing rapid clinical decompensation...

Thyroid storm, though extremely rare in toddlers, requires prompt diagnosis and treatment because it can be fatal if left untreated. However, thyroid storm is not often considered in the differential diagnosis of a febrile convulsion due to its rarity in children. Herein, we report the case of a 3-year-old girl with thyroid storm who presented with febrile status epilepticus. Although the seizure was stopped by diazepam administration, her tachycardia and widened pulse pressure persisted, and severe hypoglycemia was observed...

BACKGROUND: Neonatal meningitis due to Cronobacter is associated with powdered infant formula. Prompt recognition of this rare but aggressive infection is critical. OBSERVATIONS: The authors report a unique case of neonatal Cronobacter meningoencephalitis complicated by brain abscess and status epilepticus, requiring surgical intervention in a preterm 4-week-old male and related to contaminated powdered infant formula. They discuss the medical and surgical management in this patient, as well as the role of epilepsy surgery in acute drug-resistant epilepsy...

INTRODUCTION: New-onset super-refractory status epilepticus (NOSRSE) is a neurological emergency characterised by the development of status epilepticus in a patient without epilepsy or any known prior neurological disease and with no clear structural, toxic or metabolic cause, which recurs after 24 hours of induced coma. The most common identifiable cause is inflammatory-autoimmune. Consequently, we present a case of NOSRSE related to SARS-CoV-2 vaccination as an opportunity to investigate the dysimmune origin of this pathology...

Immunocompromised patients are at risk of developing atypical herpes simplex virus (HSV) infection, which can be easily misdiagnosed. We present a case of a 69-year-old female who was receiving methotrexate and tofacitinib for a known case of rheumatoid arthritis. She was admitted to the ICU under neurology care after presenting with status epilepticus secondary to bacterial meningitis. She complained of a group of vesicles on the erythematous base accompanied by a burning sensation, erosions with a hemorrhagic crust that extended onto the vermilion lip, and painful oral mucosa erosion that involve the buccal, palatine, and tongue...

Cortical ribbon is an uncommon finding that is characteristic of Creutzfeldt-Jakob disease but has a broad differential diagnosis. On the other hand, crossed cerebellar diaschisis is also an uncommon finding in brain magnetic resonance imaging (MRI). Herein, we are describing an 88-year-old male patient with dementia, ambulatory dysfunction, and frequent falls who presented with acute on chronic right-sided subdural hemorrhage that was discovered after an episode of seizure. Although the subdural hemorrhage was associated with mild midline shift and lateral ventricle compression, no surgical drainage was attempted, and only middle meningeal artery embolization was pursued...

PURPOSE OF REVIEW: Recent years have seen a dramatic increase in the identification of autoimmune encephalitis (AE) and the emergence of new causes of infectious encephalitis (IE). However, management of these patients remains challenging, with many requiring care in intensive care units. Here, we describe recent advances in the diagnosis and management of acute encephalitis. RECENT FINDINGS: Advances in the identification of clinical presentations, neuroimaging biomarkers, and electroencephalogram patterns have enabled more rapid diagnosis of encephalitis...

We describe a 50-year-old woman who was recently diagnosed with tuberculosis, with acute alteration in mental status. EEG showed nonconvulsive status epilepticus features. Brain MRI revealed multiple ring-enhancing lesions. She responded well to treatment for both status epilepticus and tuberculosis. Her level of consciousness improved and she became fully aware.

The study compared the clinical profile and outcomes of Japanese encephalitis (JE) and acute encephalitis syndrome (AES) in children. Fifty-six consecutive children with symptoms fulfilling the WHO clinical case definition of AES from June 2018 to June 2020 were included in the study. All patients who tested positive for either serum or cerebrospinal fluid (CSF) anti-JE-IgM antibodies were JE patients (n = 24) and compared with non-JE AES cases (n = 32). Fever, seizures, and altered sensorium were the most common presenting symptoms...

Corticosteroids are commonly used in children with bacterial meningitis; however, there are very few data regarding possible utility in neonates, particularly those born premature. We describe our experience using hydrocortisone in the treatment of a girl born at 26 weeks, 6 days gestation. She had suffered profound brain injury following late onset group B streptococcus sepsis and meningitis, and developed drug-resistant seizures. Because seizures continued despite treatment with phenobarbital, phenytoin, levetiracetam, lacosamide, and midazolam, intravenous hydrocortisone was added...

Brucellosis is a common infection that rarely causes cerebral venous sinus thrombosis (CVST). In this case, a 23-year-old male presented to the emergency department with status epilepticus. With a past medical history of drinking unpasteurized camel milk, elevated inflammatory markers, and evidence of brucellosis in the serum, the patient was diagnosed with brucellosis. Further investigations revealed left transverse sinus thrombosis extending to the jugular vein. The patient was treated with enoxaparin and a combination of doxycycline, ceftriaxone, and trimethoprim-sulfamethoxazole...
