Abstract: It is clear that some synovial inflammation occurs in joints affected by osteoarthritis (OA) and it is well recognized that many patients with OA experience a decrease in pain and joint stiffness following administration of salicylates or other nonsteroidal antiinflammatory drugs (NSAIDs). However, neither the extent to which synovitis contributes to the cartilage breakdown in OA nor the effects of chronic administration of NSAIDs on the natural history of OA in humans is known. Recent studies indicate that several NSAIDs, including salicylates, suppress proteoglycan synthesis in articular cartilage in vitro. The effect on OA cartilage is more marked than that on normal cartilage. Other studies show that salicylate feeding may suppress proteoglycan metabolism in degenerating cartilage in vivo, aggravating the decrease in proteoglycan content caused by the disease itself. However, no effect of salicylates on normal articular cartilage has been observed in vivo. In damaged cartilage the magnitude of NSAID-induced suppression of proteoglycan metabolism appears to be related inversely to the proteoglycan content of the tissue. In addition, the NSAIDs used in treatment of arthritis today may differ with respect to their in vivo effects on articular cartilage metabolism due, in part, to differences between the molar concentrations of these drugs in synovial fluid.

Abstract: Patients with malignant lymphoproliferative diseases, ie, chronic lymphocytic leukemia and lymphoma, were found to have higher porphobilinogen deaminase (PBGD) activity in their peripheral lymphocytes than normal control subjects, patients with other malignant neoplasms, and patients with various infectious diseases. The specificity and sensitivity of the test were 99% and 87%, respectively. The sensitivity of the test was 100% in patients with chronic lymphocytic leukemia and 82% in patients with lymphoma. The diagnostic value of PBGD determinations was shown in a prospective study of a group of patients evaluated because of fever of unknown origin, anemia, or other constitutional symptoms with or without lymphadenopathy or a mediastinal mass. The positive and negative predictive values in these patients were 91% and 100%, respectively. Nearly all patients who were in remission had normal enzyme activity. Lymphocyte PBGD determinations also may be of value in determining when to terminate or reinitiate drug treatment.

Abstract: Presented is a case where the death was attributed to the deliberate ingestion of an overdose of verapamil (V). Blood, urine, and gastric concentrations of the drug were determined by gas chromatography with nitrogen phosphorus detection (GC-NPD). Identification of norverapamil (NV) was made. A presumptive identification of o-demethylnorverapamil (DNV) was also made.
