Insights

Lumbar puncture (LP) in febrile children can reveal meningitis or other serious bacterial infections. For children under two with normal cerebrospinal fluid, blood, urine, and stool cultures are recommended.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Emergency Medicine

Background:

  • Lumbar puncture (LP) is a common procedure in pediatric emergency departments for diagnosing meningitis in febrile infants and young children.
  • Children undergoing LP may have other serious bacterial infections even if meningitis is not present.

Purpose of the Study:

  • To survey lumbar punctures performed in a pediatric emergency department.
  • To monitor the incidence of meningitis and other serious bacterial infections in children undergoing LP.

Main Methods:

  • Retrospective survey of lumbar punctures performed at Boston City Hospital Pediatric Emergency Department.
  • Monitoring of meningitis diagnosis and positive cultures (blood, urine, stool) in children with normal cerebrospinal fluid.

Main Results:

  • Meningitis was diagnosed in 8% of children who underwent LP.
  • An additional 10.5% of children with normal cerebrospinal fluid had positive blood (3.1%), urine (4.1%), or stool (3.3%) cultures.
  • The decision to perform LP identifies children at risk for serious bacterial illnesses beyond meningitis.

Conclusions:

  • Children undergoing lumbar puncture are at risk for both meningitis and other serious bacterial infections.
  • For children aged 2 years and younger with normal cerebrospinal fluid after LP, consider blood, urine, and possibly stool cultures to detect other infections.

Bacterial Meningitis

Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
Bacterial Meningitis II: Pathophysiology01:26

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
