Insights

Rhabdomyomas, often linked to tuberous sclerosis complex, can infiltrate the heart. A rare ECG pattern was observed in a severe neonatal case, highlighting potential conduction system destruction and arrhythmias.

Area of Science:

  • Pediatric Cardiology
  • Genetics
  • Oncology

Background:

  • Rhabdomyomas are the most common cardiac tumors in children.
  • They are frequently associated with tuberous sclerosis complex (TSC), an autosomal dominant disorder.
  • TSC involves tumor-like malformations across multiple organ systems.

Purpose of the Study:

  • To describe a rare electrocardiogram (ECG) pattern.
  • To highlight this pattern in a severe neonatal case of tuberous sclerosis complex.

Main Methods:

  • Case report of a severe neonatal tuberous sclerosis complex.
  • Electrocardiogram (ECG) analysis.

Main Results:

  • A rare ECG pattern was identified in a severe neonatal TSC case.
  • Significant rhabdomyomatosis can lead to myocardial infiltration by rhabdomyoma-like cells.
  • Increased areas of fibrosis were observed in the myocardium.

Conclusions:

  • Rhabdomyomas may spontaneously regress, necessitating close follow-up in stable cases.
  • Diffuse rhabdomyomatosis can destroy the conduction system, leading to arrhythmias.
  • This case underscores the importance of recognizing specific ECG patterns in neonatal TSC.

Aggression01:47

Aggression

Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

The Evidence for Evolution02:55

The Evidence for Evolution

Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Convergent Evolution01:54

Convergent Evolution

Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Fixed Action Patterns01:06

Fixed Action Patterns

A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Genome Size and the Evolution of New Genes

While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Gene Evolution - Fast or Slow?

The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...
