![]() Since headache is a common manifestation of intracranial diseases high index of suspicion is needed. It is important to recognize the condition immediately as rebleed in case of aneurysmal cause can be catastrophic. In severe cases patients can present with loss of consciousness (LOC), seizures, cranial nerve palsies and various patterns of motor deficits. Most commonly patients present with acute onset severe headache increasing intensity within one hour of onset and often describing as worst headache of their life. The causes for SAH can be due to rupture of intracranial aneurysms, arteriovenous malformations (AVM), vasculitis, traumatic or idiopathic. Subarachnoid Hemorrhage (SAH) is one of the acute neurological condition needing intensive care admission of the patient. 2 In some clinical conditions, lumbar puncture and drainage of can be a therapeutic measure also. CSF analysis usually consists of opening pressure measurement, biochemical analysis, cytology, biomarkers assay, and microbiological evaluation. CSF analysis is particularly useful in various acute neurological conditions and helps in rapid diagnosis of the conditions and initiate therapeutic measures. Hence analysis of CSF by various methods will help in diagnosis as well as prognostication and response to therapy. However in disease conditions the composition and pressure of CSF can be altered. The composition of the CSF and its pressure is maintained relatively constant by various mechanisms. ![]() It also supplies nutrients as well as helps in removal of various substances like amino acids, neurotransmitters, metabolic byproducts and cells. 1 The main function of the CSF is to reduce buoyancy of the brain. CSF is produced at a rate of 0.2–0.7 mL per minute or 500–700 mL per day. The total volume of CSF in the adult is approximately 140 mL. It is continuously being secreted by the choroid plexus at a constant rate inside the ventricles of the brain and circulates in the subarachnoid space of the brain and spinal cord through CSF pathways. CSF is present in both the intracranial and spinal compartments. 2000 20(3):307-22.Cerebrospinal fluid is a clear fluid which is formed as a ultra filtrate of plasma.

The incidence of fungal meningitis is increasing worldwide due to the increasing number of patients immunosuppressed by pharmacologic agents and the ongoing burden of HIV-associated cryptococcal meningitis in resource-limited countries. All major fungal pathogens have the capacity to cause meningitis. Meningitis is an inflammatory disease of the leptomeninges. Interim guidance for the diagnosis and management of fungal meningitis associated with this outbreak is available and is being updated as the ongoing investigation develops.įungus Education Hub: interim recommendations for diagnosis and management of cases of fungal meningitis associated with epidural anesthesia administered in Matamoros, Mexico To date, over 200 people in 25 states have been identified as being at risk, and four patients have died. Given the potential high case-fatality rate of central nervous system Fusarium infections and the latency of symptom onset, the CDC advises that all exposed patients should receive a lumbar puncture to test for fungal meningitis, regardless of symptoms. Fungal signals consistent with the Fusarium solani species complex were detected in cerebrospinal fluid of patients receiving care. The Centers for Disease Control and Prevention (CDC) has advised of an ongoing multistate outbreak of fungal meningitis among patients who received procedures under epidural anesthesia at two centers in Matamoros, Mexico during January 1–May 13, 2023. CDC advises of fungal meningitis outbreak associated with procedures performed under epidural anesthesia in Matamoros, Mexico
