[Changes in the buccal epithelium in certain diseases in children]
Insights
This study examined buccal epitheliocytes in children aged 1-5 years. Cell size and cytolysis measurements correlated with hematological deviations in children with bronchopulmonary and somatic diseases.
Area of Science:
- Pediatric Medicine
- Cell Biology
- Clinical Diagnostics
Background:
- Buccal epitheliocytes offer a non-invasive method for assessing cellular health.
- Pediatric diseases can manifest with subtle cellular changes.
- Hematological parameters are standard indicators of child health.
Purpose of the Study:
- To evaluate quantitative changes in buccal epitheliocytes in children.
- To correlate these cellular changes with hematological status in sick children.
- To explore the diagnostic potential of buccal cell analysis.
Main Methods:
- Collection of buccal epitheliocytes from children aged 1-5 years (healthy and sick).
- Measurement of maximal, minimal, and mean epitheliocyte size.
- Estimation of the percentage of cell cytolysis.
- Derivation of an integral index based on quantitative parameters.
Main Results:
- Quantitative parameters of buccal epitheliocytes were measured.
- An integral index reflecting cellular changes was developed.
- This index showed a positive correlation with hematological parameter deviations.
- Findings were observed in children with bronchopulmonary and somatic diseases.
Conclusions:
- Quantitative analysis of buccal epitheliocytes can indicate health status in children.
- Buccal cell morphology changes correlate with systemic health indicators.
- This approach may aid in the early detection and monitoring of pediatric diseases.
Abstract:
Buccal epitheliocytes collected from healthy and sick children aged 1 to 5 years were examined. The maximal and minimal size of epitheliocytes was measured and their mean size estimated, as was the percent share of cell cytolysis. An integral index derived on the basis of these measurements reflects the degree of change in the quantitative parameters characterizing the buccal epitheliocytes and is in positive correlation with deviations of hematological parameters from the norm in children with bronchopulmonary and somatic disease.

Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
