Correlation of induced sputum eosinophil levels with clinical parameters in mild and moderate persistent asthma in children aged 7-18 years.

Background: Treatment decisions in asthma are currently based on clinical assessment and spirometry. Sputum eosinophil, being a marker of airway inflammation, can serve as a tool for assessing severity and response to treatment in asthma patients.

Objectives: To measure eosinophil percentage in induced sputum in children with asthma and correlate it with clinical asthma parameters.

Severe acute respiratory distress syndrome caused by unintentional sewing machine lubricant ingestion: A case report.

Sewing machine oil ingestion is rare but is possible due to its availability at home. Chemically, it belongs to hydrocarbon family which is toxic if aspirated, owing to their physical properties such as high volatility and low viscosity. On the contrary, sewing machine lubricant has high viscosity and low volatility which makes it aspiration less likely.

Induced Sputum Nitrite Levels Correlate with Clinical Asthma Parameters in Children Aged 7-18 Years with Mild to Moderate Persistent Asthma.

Purpose: The objective of this study is to measure levels of nitrites in induced sputum in children with asthma and correlate it with clinical asthma parameters.

Method: This prospective observational study was done in PGIMER, Dr. Ram Manohar Lohia Hospital, New Delhi, on 91 children aged 7-18 years with mild and moderate persistent asthma.
