Abstract

Abstract: Cerumen impaction is a common otologic problem that can impair hearing and predispose individuals to external ear infections. This in vitro study aimed to compare the cerumenolytic effects of propolis and 3% hydrogen peroxide using spectrophotometric absorbance measurements at 5, 10, 15, and 30 minutes. A total of 48 cerumen samples were collected from children at Panti Asuhan Putri Aisyiyah Medan and divided equally into two treatment groups. Absorbance values were analyzed using non-parametric statistical tests due to non-normal data distribution. Propolis demonstrated a progressive increase in absorbance over time, reaching its highest effect at 30 minutes, whereas hydrogen peroxide showed minimal changes with no significant time-dependent pattern. Comparative analysis revealed that propolis produced significantly higher absorbance values than hydrogen peroxide at all time points (p 0.001), indicating superior cerumen dissolution. These findings suggest that propolis may serve as a more effective and potentially safer alternative to hydrogen peroxide for cerumen management. Further in vivo and clinical studies are recommended to validate its therapeutic applicability and long-term safety.

Abstract

Recurrent acute respiratory infections (ARI) in adults continue to pose a significant public health burden, particularly in communities where adherence to preventive behaviors is inconsistent. This study aimed to examine the association between preventive health behaviors and recurrent ARI using a case-based epidemiological approach. A cross-sectional analysis was conducted among 106 adults diagnosed with ARI, and data were collected using a structured questionnaire adapted from PHBS indicators assessing hand hygiene, respiratory etiquette, mask use during illness, smoking inside the home, physical distancing when symptomatic, and healthcare-seeking practices. Recurrent ARI was defined as three or more episodes within the previous 12 months, and associations were analyzed using the Chi-Square test with a significance level of p < 0.05. Several preventive behaviors, including inadequate hand hygiene, poor respiratory etiquette, limited mask use, and delayed medical consultation, showed significant relationships with recurrent ARI, with inconsistent behaviors markedly elevating recurrence risk. These findings suggest that strengthening behavior-focused health education in primary care, particularly hygiene promotion, responsible respiratory practices, mask use during illness, and timely care-seeking, may help reduce recurrent ARI among adults.
