Insights

A rare genetic liver condition, progressive familial intrahepatic cholestasis type 2 (PFIC2), can cause severe vitamin K deficiency bleeding (VKDB) in infants. This case highlights the need for comprehensive diagnosis beyond abusive head trauma for intracranial hemorrhages.

Area of Science:

  • Pediatrics
  • Genetics
  • Hematology

Background:

  • Abusive head trauma (AHT) is a critical medical emergency requiring prompt identification to prevent further harm.
  • Intracranial hemorrhage in infants necessitates a thorough diagnostic evaluation to rule out various underlying causes.

Observation:

  • A 4-month-old infant presented with a severe subdural hematoma.
  • Initial suspicion of AHT was raised.
  • Testing revealed vitamin K deficiency bleeding (VKDB) despite prophylaxis.
  • The infant was diagnosed with progressive familial intrahepatic cholestasis type 2 (PFIC2).

Findings:

  • PFIC2, a rare genetic liver disorder, can lead to severe VKDB.
  • This is the first reported case of PFIC2 causing intracranial hemorrhage due to VKDB.

Implications:

  • Comprehensive workup is essential for intracranial bleeding in infants.
  • Consider rare genetic conditions beyond AHT and standard VKDB.
  • This case broadens the differential diagnosis for infantile intracranial hemorrhage.

Protein Families

Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism.   Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members.   If these new proteins contain similar amino acids in key...

Gene Families01:57

Gene Families

Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Drug Abuse and Addiction: Pharmacological Phenomena

Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Bleeding in Fresh Concrete01:22

Bleeding in Fresh Concrete

Bleeding in fresh concrete occurs when water from the mix rises to the surface. This happens because the mix's solid components fail to retain all the water as they settle, leading to separation where water collects at the top. The severity of bleeding can be measured by assessing the total settlement or by noting the decrease in height per unit height of concrete.
Bleeding can cause several issues in the concrete structure. Sometimes, the rising water gets trapped beneath large aggregate...
