I want to find all instances of silo workers' asthma and red cedar asthma in the database, with a specificity scale of 0 and an accuracy scale of 100, using the ICD-9 coding system for diagnoses and including any timing. The query will search for these conditions in the Respiratory System category, under Lung Diseases due to External Irritants and Chronic Obstructive Diseases, respectively.
