Resumen
La meningitis por Listeria monocytogenes es rara en niños sanos pero puede ocurrir. Este estudio destaca la importancia de considerar esta infección incluso sin factores de riesgo típicos en casos pediátricos.
Área de la Ciencia:
- Enfermedades Infecciosas Pediátricas
- Neurología
- Microbiología
Sus antecedentes:
- La meningitis por Listeria monocytogenes afecta típicamente a poblaciones vulnerables.
- Las infecciones en niños inmunocompetentes se informan con poca frecuencia y se consideran inusuales.
Objetivo del estudio:
- Analizar casos de meningitis por Listeria monocytogenes en niños inmunocompetentes.
- Identificar características clínicas, hallazgos diagnósticos y respuestas al tratamiento en esta población.
Principales métodos:
- Análisis retrospectivo de historias clínicas.
- Inclusión de siete niños previamente sanos de 4 meses a 15 años.
- Revisión de cursos clínicos, hallazgos de laboratorio, imágenes médicas y resultados del tratamiento.
Principales resultados:
- Los síntomas comunes incluyeron fiebre, convulsiones, vómitos, dolor de cabeza y alteración de la conciencia.
- Se observaron signos de edema cerebral en tres pacientes; afectación de nervios craneales en dos.
- Se observó realce leptomeníngeo en la RM en cuatro pacientes.
Conclusiones:
- Se debe considerar la meningitis por Listeria monocytogenes en niños que presentan síntomas de meningitis, incluso sin factores de riesgo aparentes.
- El diagnóstico y tratamiento tempranos son cruciales para resultados favorables en casos pediátricos.

01:18Viral 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...
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
01:22Bacterial 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...
01:26Bacterial 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...
01:19Encephalitis 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...
