Insights

Post-meningitis in children can cause significant sensorineural hearing loss, especially in younger children. This study found 36.6% of children aged 6-36 months had hearing deficits after meningitis.

Area of Science:

  • Pediatrics
  • Neurology
  • Audiology

Background:

  • Meningitis is a serious infection that can lead to long-term complications in children.
  • Sensorineural hearing loss is a potential sequela of meningitis, impacting child development.
  • Early identification of hearing deficits is crucial for timely intervention.

Purpose of the Study:

  • To assess the prevalence and degree of sensorineural hearing loss in children who have recovered from meningitis.
  • To identify risk factors associated with hearing impairment in post-meningitic children.

Main Methods:

  • Brainstem Evoked Response Audiometry (BERA) was performed on 30 children with a history of meningitis.
  • A control group of 15 age-matched normal children was included for comparison.
  • Hearing loss was categorized by severity (moderate, severe) and laterality (unilateral, bilateral).

Main Results:

  • 36.6% of post-meningitic children (aged 6-36 months) exhibited sensorineural hearing loss.
  • Severe bilateral hearing loss (>80 dB) was found in 6.6%, and moderate hearing loss (40-80 dB) in 30%.
  • Higher incidence of hearing loss correlated with younger age at meningitis onset and history of seizures.

Conclusions:

  • Meningitis poses a significant risk for developing sensorineural hearing loss in young children.
  • Younger age and seizure occurrence during meningitis are associated with increased risk of hearing impairment.
  • Regular audiological monitoring is recommended for children recovering from meningitis.

Assessment of Respiration

The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...
Bacterial Meningitis01:24

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...
