Insights

Posterior reversible encephalopathy syndrome (PRES) is a serious complication after pediatric stem cell transplants, often linked to immunosuppressants like cyclosporine. Early detection and monitoring are crucial for managing PRES and improving transplant outcomes in children.

Area of Science:

  • Pediatric Hematology/Oncology
  • Neuroscience
  • Transplantation Medicine

Background:

  • Posterior reversible encephalopathy syndrome (PRES) is a significant complication following allogeneic stem cell transplantation (ASCT) in children.
  • It is frequently associated with immunosuppressive therapies used during transplantation.

Observation:

  • A case study of a 7-year-old girl with myelodysplastic syndrome (MDS) who developed PRES post-ASCT.
  • PRES diagnosis was confirmed via imaging within the first month, strongly suggesting cyclosporine neurotoxicity.

Findings:

  • PRES contributes to increased transplant-related mortality in pediatric patients.
  • Cyclosporine-induced neurotoxicity is a likely cause of PRES in this case.

Implications:

  • Early identification of PRES risk factors and vigilant monitoring of vital signs (blood pressure, neurological status, vision) are essential.
  • This approach may allow for the use of immunosuppressive agents with lower neurological toxicity.
  • Further research is needed to confirm the impact of PRES on transplant outcomes.

Adult Stem Cells

Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Induced Pluripotent Stem Cells

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...

Embryonic Stem Cells

Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Embryonic Stem Cells

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Diode: Reverse bias01:14

Diode: Reverse bias

A diode is reverse-biased when the positive terminal of an external voltage source is connected to the n-type material and the negative terminal to the p-type material. This configuration opposes the natural direction of current flow through the diode, effectively increasing the width of the depletion region and the barrier potential. The reverse bias condition produces a minimal leakage current, primarily due to minority charge carriers. This leakage becomes significant when the reverse...

Reversible and Irreversible Processes

The thermodynamic processes can be classified into reversible and irreversible processes. The processes that can be restored to their initial state are called reversible processes. It is only possible if the process is in quasi-static equilibrium, i.e., it takes place in infinitesimally small steps, and the system remains at equilibrium However, these are ideal processes and do not occur naturally. An ideal system undergoing a reversible process is always in thermodynamic equilibrium within...
