Summary
Particulate matter, including PM10 and PM2.5, did not correlate with psoriasis hospital visits in South Korea. Advanced statistical methods confirmed no link between air pollution and psoriasis exacerbation frequency.
Area of Science:
- Environmental Health
- Dermatology
- Epidemiology
Background:
- Particulate matter is known to trigger inflammatory responses in chronic skin conditions.
- Previous research has not investigated the link between particulate matter exposure and psoriasis flare-ups.
Purpose of the Study:
- To assess the association between exposure to particulate matter and hospital visits for psoriasis.
- This study focused on patients in seven major South Korean cities.
Main Methods:
- Utilized data from the Korean National Health Insurance Service for psoriasis patients.
- Collected 3-year data on PM10 and PM2.5 concentrations from the Korea Environment Corporation.
- Employed time series regression and prewhitening methods to analyze correlations.
Main Results:
- Initial analyses indicated a correlation between particulate matter levels and psoriasis-related hospital visits.
- However, after applying prewhitening to control for confounding variables, this correlation disappeared.
- The study found no statistically significant relationship between particulate matter and psoriasis exacerbation.
Conclusions:
- Particulate matter exposure does not appear to influence the frequency of hospital visits for psoriasis among urban South Korean populations.
- Further research may be needed to explore potential indirect effects or different exposure scenarios.

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

01:30Pneumonia I: Introduction
377
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
