Insights

Human parechovirus (HPeV) can cause severe illness in newborns, presenting with sepsis-like symptoms and neurological issues. Early HPeV detection is crucial for prompt diagnosis and management in infants.

Area of Science:

  • Virology
  • Neonatal Medicine
  • Pediatric Infectious Diseases

Background:

  • Human parechovirus (HPeV) is a known pathogen linked to central nervous system infections and sepsis-like illnesses in neonates.
  • Common clinical manifestations include fever, seizures, irritability, rash, and encephalitis.

Observation:

  • This report details 4 cases of full-term infants diagnosed with HPeV infection in October 2012.
  • Median age at symptom onset was 15 days, with presentations of sepsis-like illness, gastrointestinal issues, and irritability.
  • Two infants experienced respiratory distress, two developed skin rashes, and two required intensive care unit admission.

Findings:

  • Laboratory findings included normal or mild inflammatory markers, normal or low white blood cell counts, and hepatitis.
  • Notably, elevated muscular enzymes were observed for the first time in 3 of the affected infants.
  • HPeV infection was confirmed via real-time PCR in cerebrospinal fluid and/or blood samples.

Implications:

  • HPeV can lead to severe neonatal disease, necessitating evaluation in infants presenting with similar symptoms.
  • Consideration of HPeV is important in cases of sudden infant death syndrome.
  • This study highlights the potential severity of HPeV in neonates and introduces elevated muscular enzymes as a potential diagnostic marker.

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...
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...

Myocarditis II: Clinical Features and Diagnostic Tests

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
Encephalitis ll: Pathophysiology01:26

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
Bacterial Meningitis I: Introduction01:22

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 Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
