Summary
Patch testing practice among Chinese dermatologists shows little improvement since 2006. While many perform the test, perceptions and training require further enhancement for better allergic contact dermatitis diagnosis.
Area of Science:
- Dermatology
- Allergic Contact Dermatitis Diagnosis
Background:
- Patch testing is the standard diagnostic method for allergic contact dermatitis (ACD).
- A previous 2006 survey indicated widespread but unsatisfactory patch testing practices among Chinese dermatologists.
Purpose of the Study:
- To assess the current status of patch testing practices and perceptions among Chinese dermatologists.
- To identify changes and persistent issues in patch testing since the 2006 survey.
Main Methods:
- A cross-sectional survey was conducted using electronic questionnaires.
- Data were collected from Chinese dermatologists at the 15th National Congress of Dermatology in November 2019.
Main Results:
- Approximately 75% of dermatologists perform patch testing, with increased use of non-Chinese allergen series compared to 2006.
- Most dermatologists perform single readings, and while patient education is offered, it's often not by trained professionals.
- Dermatologists in regional hospitals demonstrated higher performance and better perception, despite the majority having received training.
Conclusions:
- There has been minimal improvement in patch testing practice and perception among Chinese dermatologists since 2006.
- Further educational initiatives and studies are recommended to enhance patch testing.
- Cross-national surveys are suggested to compare practices globally.

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Many fundamental cell functions such as muscle contraction and nerve transmission rely on the electrical signals produced by the movement of positively and negatively charged ions across the cell membrane. One competent method to record current flowing across the whole cell or single ion channel is the patch-clamp technique.
In this method, a glass micropipette containing electrolyte solution is tightly sealed against a small portion of the cell membrane. As a result, a patch of the cell...
