Induced Pluripotent Stem Cells

28.2K
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

Vision

60.3K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Summary
This summary is machine-generated.

Retinitis post febrile illness (RpFI) shows seasonal patterns, peaking in winter months. While presenting aggressively, this condition typically resolves within 3-4 months, leading to satisfactory visual outcomes.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Epidemiology

Background:

  • Retinitis post febrile illness (RpFI) is a recognized condition.
  • Understanding its characteristics is crucial for diagnosis and management.

Purpose of the Study:

  • To investigate the demography, seasonal incidence, clinical features, and treatment outcomes of RpFI.
  • To propose a new term for RpFI based on its epidemiological characteristics.

Main Methods:

  • Retrospective analysis of case records for patients diagnosed with RpFI between July 2009 and May 2017.
  • Evaluation of treatment and visual outcomes in patients with complete follow-up data.

Main Results:

  • The study included 205 eyes from 119 patients, with a peak incidence from November to March.
  • Fever diagnosis was often unknown; specific serological tests showed positivity for Chikungunya, Dengue, and Weil-Felix.
  • Mean visual acuity improved from 20/63 at presentation to 20/32 at resolution in 122 eyes.

Conclusions:

  • A new term, "Epidemic Retinitis," is suggested for RpFI due to its seasonal variation and to distinguish it from sporadic retinitis.
  • Despite aggressive initial presentation, RpFI demonstrates a favorable prognosis with resolution in 3-4 months and satisfactory visual recovery.
