Clinician's Corner: Tips on how to study smarter - Duration: The prevalence of serum sickness has decreased dramatically because animal anti-serum is rarely used to treat or prevent infectious diseases. Chronic allergic bronchial asthma loses reversibility and is indistinguishable from chronic obstructive pulmonary disease COPD. Insulin allergy. Pharmacology Animation 9, views. Serum sickness can be induced with massive injections of foreign antigen. Allergic rhinitis must rule out other causes of rhinitis including vasomotor, non-allergic rhinitis with eosinophilia, drug-induced cocaine abusemechanical tumors, foreign body, sarcoidosis and infectious including viral, bacterial and leprosy. Classic examples are food allergies and hay fever to ragweed pollen.
