1.4 Chemical Determination. Proteins are complex, organic compounds composed of many amino acids linked together through peptide bonds and cross-linked between chains by sulfhydryl bonds, hydrogen bonds and van der Waals forces.
Common causes of pleurisy include trauma, postcardiac injury, infection (i.e., viral, bacterial, or parasitic), respiratory illness, caustic exposure (i.e., drug-induced), autoimmune disease, and malignancy (TABLE 1).
Pleurisy is a condition in which pleuritic chest pain may evolve as a symptom secondary to a primary cause. NSAIDs (particularly indomethacin), along with opioid analgesics, remain the mainstay of treatment for pleurisy; identification and treatment of the primary cause are also important.
