Successful Management of Two Patients with Intracranial Hemorrhage due to Carpet Viper (Echis ocellatus) Envenomation in a Limited-Resource Environment
We present 2 cases of E ocellatus envenomation with intracranial hemorrhage seen at a rural hospital in Bembèrèkè, Benin, and describe the successful management of these patients in a limited-resource setting. In one case the patient was treated with an ineffective Indian-made antivenom before evaluation by the authors and continued to deteriorate until she was treated with effective antivenom 10 d after the bite. In both cases lumbar puncture was performed for diagnostic or therapeutic purposes with good effect, and both patients made full recoveries without sequelae. These cases demonstrate the remar...

Does CSF pleocytosis have a predictive value for disease course in MS?
Objective MS is a demyelinating CNS disorder with a spectrum of clinical patterns regarding course and prognosis. Although several prognostic factors are considered in the initial evaluation of patients, biological markers defining the disease course and guiding treatments are currently lacking. It is unknown whether patients with CSF pleocytosis differ in regard to symptoms, disease course, and prognosis from those without. The aim of this study was to evaluate whether CSF pleocytosis during the initial presentation has an impact on the clinical course and progression of MS. Methods We retrospectively evaluated patients ...

Biomarkers for Alzheimer's Disease in Saliva: A Systematic Review.
Conclusion: Aβ42 and tau seem to be worthy candidates for future salivary biomarkers for AD, but other biomarkers such as lactoferrin and selected metabolites also have potential. More studies must be carried out with larger sample sizes and a standardization of the sampling and processing method. Factors such as diurnal variation, AD patients' decreased ability of oral self-care, and salivary flowrates must be taken into consideration.

Cancers, Vol. 11, Pages 824: Improving the Brain Delivery of Chemotherapeutic Drugs in Childhood Brain Tumors
pozza Ruggiero The central nervous system (CNS) may be considered as a sanctuary site, protected from systemic chemotherapy by the meninges, the cerebrospinal fluid (CSF) and the blood-brain barrier (BBB). Consequently, parenchymal and CSF exposure of most antineoplastic agents following intravenous (IV) administration is lower than systemic exposure. In this review, we describe the different strategies developed to improve delivery of antineoplastic agents into the brain in primary and metastatic CNS tumors. We observed that several methods, such as BBB disruption (BBBD), intra-arterial (IA) and intracavitary chemo...

Swollen optic nerve: an approach to diagnosis and management.
Abstract The differential diagnosis of swollen optic nerves differs according to whether the swelling is unilateral or bilateral, or whether visual function is normal or affected. Patients with a unilaterally swollen optic nerve and normal visual function most likely have optic nerve head drusen. Patients with abnormal visual function most likely have demyelinating optic neuritis or non-arteritic anterior ischaemic optic neuropathy. Patients with bilaterally swollen optic nerve heads and normal visual function most likely have papilloedema, and require neuroimaging followed by lumbar puncture. However, if their vi...

The Influence of Blood Contamination on Cerebrospinal Fluid Diagnostics
Conclusion: Erythrophages and siderophages do not develop in vitro. An extensive diagnostic work up for the source of blood in the CSF should be performed when erythrophages or siderophages are found in the CSF. The contamination of CSF with increasing volume of blood resulted in falsely elevated CSF protein concentrations. Hence, the amount of blood contamination has to be taken into consideration when interpreting CSF protein measurement results. (Source: Frontiers in Neurology)

ConclusionThe PCB and MFS variant are rare forms of GBS. Ataxia commonly described in both of our cases may lead to overlapping syndrome and supports the view that PCB and MFS belongs to a continuous spectrum. Ataxia makes also difficult to differentiate these clinical entities from brainstem injury. However, areflexia and ENMG help to make the diagnosis. Further studies are needed to clarify whether these entities have specific patterns in electrophysiological studies. (Source: Neurophysiologie Clinique)

Crowned dens syndrome: a neurologist ’s perspective
We present a 48-year-old woman presenting with an inflammatory meningitis-like syndrome with headache and neck stiffness. Lumbar puncture was normal and computed tomography (CT) of the atlantoaxial joint showed abnormal calcifications around the odontoid process, leading to a tentative diagnosis of crowned dens syndrome. In addition, signs of active inflammation in and around the dens were present on cervical MR imaging. Since CDS can mimic meningitis or giant-cell arteritis, neurologists should be aware of this entity. If CDS is suspected, the bone window on the head CT scan can lead to the diagnosis. On the other hand, a...

Immune reconstitution inflammatory syndrome causing progressive optic nerve edema in cryptococcal meningitis
Conclusion: Recurrent optic disk edema with loss of vision after treatment of cryptococcal meningitis in the setting of normal intracranial pressure may represent a unique manifestation of immune reconstitution inflammatory syndrome localized to the optic nerve without uveitis. This is consistent with the temporal relationship between starting highly active antiretroviral therapy, CD4+ count recovery, and the development of progressive disk edema in the study patient. Isolated optic nerve inflammation as a manifestation of immune reconstitution inflammatory syndrome has not been widely reported. (Source: Retinal Cases and Brief Reports)

Age matters: Impact of data-driven CSF protein upper reference limits in Guillain-Barre syndrome
Conclusions The low sensitivity of CSF-TP for the diagnosis of GBS is exacerbated by age-adjusted upper limits. The main role of lumbar puncture in GBS in the first week may be to help exclude other inflammatory or neoplastic etiologies of acute neuropathy. After the first week, the magnitude of the CSF-TP rise reduces the effect of different upper reference limits. (Source: Neurology Neuroimmunology and Neuroinflammation)

Iatrogenic Nontraumatic CPAP-Induced Pneumocephalus in a Patient With Meningitis
We describe a case of a patient who presented with meningitis due to an atypical organism that usually resides in the oral cavity, and who developed nontraumatic pneumocephalus in the hospital due to CPAP therapy. The underlying cause, a cerebrospinal fluid leak, was likely the mediator for both pathologies.

We hypothesize that the reduction is caused by the expansion of the stenosis after lumbar puncture. Our results further show a correlation between the peak velocity and pulsatile tinnitus intensity, suggesting the flow jet to be instrumental in the development of sound.

Biochemical Differences Between Vitreous Humor and Cerebral Spinal Fluid in a Death From Diabetic Ketoacidosis
We present a case report of a 21-year-old man who died of diabetic ketoacidosis confirmed at autopsy. Ventricular system, LP, and VH were biochemically analyzed and showed that glucose was highest in VH (41 mmol/L) and was 6 and 8 mmol/L higher than CSF in the LP and VA, respectively. β-Hydroxybutyrate was also highest in VH (20 mmol/L) and was 5 and 6 mmol/L higher than LP and VA, respectively. Our findings suggest that postmortem CSF glucose and β-hydroxybutyrate may not truly reflect that of VH and vary between CSF sampling sites.

Conclusion: Accounting for brain volume derived from brain MRI is unlikely to improve the diagnostic value of protein concentrations in CSF.
