Case Report: Minimal Neurological Deficit of Two Adult Patients With Weston-Hurst Syndrome Due to Early Craniectomy: Case Series and Review of Literature on Craniectomy.

We describe two new cases of acute hemorrhagic leucoencephalitis (AHLE), who survived with minimal sequelae due to early measures against increased intracranial pressure, particularly craniotomy. The recently published literature review on treatment and outcome of AHLE was further examined for the effect of craniotomy. We present two cases from our institution.

Miliary pattern of brain metastases - a case report of a hyperacute onset in a patient with malignant melanoma documented by magnetic resonance imaging.

Background: Miliary brain metastases are a rare condition but associated with an exceedingly poor prognosis. We present the case of a patient suffering from malignant melanoma with an acute progressively worsening of neurological symptoms up to the loss of consciousness. The magnetic resonance imaging (MRI) demonstrated a new onset of disseminated, miliary spread of central nervous system metastases from a malignant melanoma within 4 days.

Complement component 5 contributes to poor disease outcome in humans and mice with pneumococcal meningitis.

Pneumococcal meningitis is the most common and severe form of bacterial meningitis. Fatality rates are substantial, and long-term sequelae develop in about half of survivors. Disease outcome has been related to the severity of the proinflammatory response in the subarachnoid space.

The chemokine CXCL13 in acute neuroborreliosis.

Objective: Recent studies have suggested an important role of the B cell chemoattractant CXCL13 in acute neuroborreliosis (NB). Our aim was to confirm the diagnostic role of CXCL13 and to evaluate its relevance as a therapy response and disease activity marker in NB.

Methods: CXCL13 was measured in cerebrospinal fluid (CSF) and serum of patients with NB (n=28), systemic borreliosis (SB, n=9), Guillain-Barré syndrome (GBS, n=11), Bell's palsy (BP, n=19), other cranial nerve palsies (CNP, n=5), cephalgia (C, n=20), bacterial CNS infections (B-CNS-I, n=16) and viral CNS infections (V-CNS-I, n=18).

Severe meningoencephalitis caused by human herpesvirus 6 type B in an immunocompetent woman treated with ganciclovir.

Human herpesvirus 6 (HHV-6), the causative agent of exanthema subitum in childhood, can also induce meningoencephalitis in immunocompromised individuals. In contrast, HHV-6 encephalitis in immunocompetent patients is rare, and the clinical syndrome not well defined. We report a case of meningoencephalitis caused by HHV-6 type B in an otherwise healthy woman.

Discrepancies between brain CT imaging and severely raised intracranial pressure proven by ventriculostomy in adults with pneumococcal meningitis.

Objectives: Computed tomography (CT) of the brain is recommended for assessment of intracranial pressure (ICP) of patients with acute bacterial meningitis who are comatose or show focal neurological deficits. The aim of this report is to draw attention to the possibility of a discrepancy between CT findings and ICP values in some patients with pneumococcal meningitis.

Methods: We describe three adult patients with pneumococcal meningitis who had both successive CT examinations and ICP measurements at the time of clinically evident cerebral herniation (n = 2) and/or prolonged coma (n = 2).

Experimental bacterial meningitis in rats: demonstration of hydrocephalus and meningeal enhancement by magnetic resonance imaging.

We investigated whether magnetic resonance imaging (MRI) is able to detect intracranial manifestations of advanced bacterial meningitis in rats. Meningitis was induced in nine animals by injecting 150 microl 10(7) colony forming units per ml of Streptococcus pneumoniae into the cisterna magna. MRI was performed 24 h (n = 5) and 48 h (n = 4) after infection.
