Insights

Identifying the cause of spastic quadriplegia in children is crucial. This study found hypoxic-ischemic perinatal asphyxia and periventricular leukomalacia are common causes, with etiology varying by gestational age.

Area of Science:

  • Pediatric Neurology
  • Developmental Neuroscience
  • Clinical Pediatrics

Background:

  • Spastic quadriplegia is a severe motor impairment in children.
  • Understanding the underlying causes is essential for effective management and intervention.
  • Etiologic diagnosis in spastic quadriplegia can be challenging.

Purpose of the Study:

  • To determine the etiologic profile of spastic quadriplegia in a pediatric cohort.
  • To identify predictors for establishing an etiology in children with spastic quadriplegia.
  • To analyze how gestational age influences the underlying causes.

Main Methods:

  • Retrospective review of medical records from a pediatric neurology practice over 14 years.
  • Inclusion of 99 children diagnosed with spastic quadriplegia.
  • Systematic assessment of demographic, prenatal, perinatal, and postnatal risk factors.

Main Results:

  • An overall etiologic yield of 83% was achieved.
  • The most frequent diagnoses were hypoxic-ischemic perinatal asphyxia (33%), periventricular leukomalacia (15%), and central nervous system infections (11%).
  • Etiologies differed based on gestational age, with periventricular leukomalacia more common in premature infants and perinatal asphyxia in term-born infants.

Conclusions:

  • The etiologic profile of spastic quadriplegia varies significantly with gestational age.
  • Factors such as male sex, low birth weight, prematurity, perinatal complications, and neonatal encephalopathy predicted a higher likelihood of identifying an etiology.
  • These findings aid clinicians in investigating the causes of spastic quadriplegia.

Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Spinal Cord Injury ll: Pathophysiology

Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
Botulism01:22

Botulism

Botulism is a life-threatening neuroparalytic condition caused by botulinum neurotoxin, which is produced by the bacterium Clostridium botulinum, a Gram-positive, spore-forming, obligate anaerobe.In adults, the toxin enters the body in different ways: in foodborne botulism, the preformed toxin is absorbed in the intestine. In wound botulism, spores grow in injured tissue and release the toxin into the blood. Infant botulism differs mechanistically from adult forms. In infants, botulism commonly...

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...
Tetanus01:29

Tetanus

Tetanus is a life-threatening neurological disorder characterized by persistent muscle contractions and spastic paralysis. It is caused by Clostridium tetani, a motile, Gram-positive, rod-shaped, obligate anaerobe. These bacteria produce terminal endospores, giving them a distinctive “lollipop” or “tennis-racket” appearance. They thrive in anaerobic environments, such as those found in deep puncture wounds.Once introduced into the body, the spores germinate into vegetative cells. These cells...
