Cerebrospinal fluid can exit into the skull bone marrow and instruct cranial hematopoiesis in mice with bacterial meningitis.

Nat Neurosci 2022 May 2;25(5):567-576. Epub 2022 May 2.

Center for Systems Biology, Massachusetts General Hospital and Harvard Medical School, Boston, MA, USA.

Interactions between the immune and central nervous systems strongly influence brain health. Although the blood-brain barrier restricts this crosstalk, we now know that meningeal gateways through brain border tissues facilitate intersystem communication. Cerebrospinal fluid (CSF), which interfaces with the glymphatic system and thereby drains the brain's interstitial and perivascular spaces, facilitates outward signaling beyond the blood-brain barrier.

Pott Puffy Tumor Caused by Dental Infection: A Case Report and Literature Review.

J Craniofac Surg 2022 Mar-Apr 01;33(2):e127-e130

Department of Otorhinolaryngology, Yonsei University Wonju College of Medicine, Wonju, South Korea.

Abstract: Pott puffy tumor (PPT), first described by Sir Percivall Pott in 1760, is a rare clinical entity characterized by a subperiosteal abscess associated with osteomyelitis of the frontal bone caused by direct or hematogenous spread. Although rare in this modern age of antibiotics, this tumor usually occurs as a complication of sinusitis. Moreover, intracranial complications such as subdural abscess, meningitis, sinus thrombosis, or brain abscess can occur concomitantly with the underlying sinusitis, despite the administration of antibiotics.

Emergency department management of adults with infectious meningitis and encephalitis.

Emerg Med Pract 2022 04 2;24(4):1-24. Epub 2022 Apr 2.

Department of Emergency Medicine, University of Texas Southwestern Medical Center, Dallas, TX.

Infectious meningitis and encephalitis are often life-threatening illnesses, though prompt workup and targeted treatment can greatly reduce morbidity and mortality. Although presentation of central nervous system infection can sometimes be subtle, this issue focuses on evidence-based strategies for identifying combinations of signs and symptoms to narrow the diagnosis. Identifying meningitis versus encephalitis; bacterial versus viral, fungal, or iatrogenic causes; and providing prompt empiric antimicrobials and appropriate diagnostic testing are key to management.

High-dose rifampin improves bactericidal activity without increased intracerebral inflammation in animal models of tuberculous meningitis.

J Clin Invest 2022 03;132(6)

Center for Infection and Inflammation Imaging Research.

Tuberculous meningitis (TB meningitis) is the most severe form of tuberculosis (TB), requiring 12 months of multidrug treatment for cure, and is associated with high morbidity and mortality. High-dose rifampin (35 mg/kg/d) is safe and improves the bactericidal activity of the standard-dose (10 mg/kg/d) rifampin-containing TB regimen in pulmonary TB. However, there are conflicting clinical data regarding its benefit for TB meningitis, where outcomes may also be associated with intracerebral inflammation. Read More

Klebsiella pneumoniae-related brain abscess and meningitis in adults: Case report.

Medicine (Baltimore) 2022 Jan;101(2):e28415

Department of Hepatobiliary Surgery, the Fourth Hospital of Hebei Medical University, 12th Jiankang Road, Shijiazhuang, P.R. China.

Introduction: Klebsiella pneumoniae is once thought to be a less common cause of brain abscess in adults and is mainly hospital-acquired. Community-acquired CNS infection (brain abscess and meningitis) caused by K pneumoniae without other metastatic septic abscesses is exceedingly rare. Therefore, we present a rare adult patient with invasive cerebral abscess and meningitis without other invasive abscesses related to K pneumoniae. Read More
