Cardiomyopathy III: Hypertrophic Cardiomyopathy

607
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Mechanism of Ciliary Motion

5.6K
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Summary
This summary is machine-generated.

A new bimanual cortical cleaning technique safely removes cataractous lens material in elderly patients with weak zonules, preserving the capsule and avoiding complications. This approach prioritizes visual axis clarity over complete cortex removal in complex cases.

Area of Science:

  • Ophthalmology
  • Cataract Surgery
  • Microsurgery

Background:

  • Complete cortical cleanup is standard to prevent posterior capsular opacification.
  • Severe zonulopathy poses risks of zonular dehiscence during complete cleanup.
  • A safe, maximal cortical cleanup technique is needed for elderly patients (>90 years) with severe zonulopathy.

Discussion:

  • Bimanual aspiration of elevated central fibers and passive removal of loose peripheral fibers is a novel approach.
  • This technique avoids capsular tension rings, using one-piece foldable intraocular lens implants.
  • Postoperative management includes corticosteroid drops.

Key Insights:

  • The technique was safely performed in eyes with pseudo-exfoliation or brunescent cataract and weak zonules.
  • No posterior capsular rupture, iritis, vitreous loss, or lens subluxation occurred.
  • Moderate capsular phimosis was observed, but central vision was maintained.

Outlook:

  • The necessity of complete cortical cleanup in severe zonulopathy warrants re-evaluation.
  • Prioritizing a clear visual axis with maximal preservation of compromised zonules is beneficial.
  • This technique is suitable for patients over 90, minimizing risks of late intraocular lens-capsule complex dislocation.
