[Q]: Abstract: Studies in patients on dialysis have shown that aluminum (Al) accumulation in bone plays a major role in the pathogenesis of osteomalacia. It has been suggested that deferoxamine (DFO) may be beneficial in the treatment of aluminum-induced osteomalacia. The present studies were performed in four groups of uremic rats to determine if DFO and/or discontinuation of Al administration have an effect on bone histomorphometry and blood chemistries. The groups were: 1) uremic control 2) aluminum (0.75 to 1.0 mg/rat i.p., five times a week for twelve weeks): 3) aluminum + DFO, after twelve weeks Al was discontinued and the rats received DFO (75 mg/rat two times a week for nine weeks); 4) aluminum + time, after twelve weeks Al was discontinued and the rats were sacrificed after nine weeks. High levels of Al in serum and bone and low levels of PTH were seen in rats receiving Al. Bone histology revealed Al at the mineralization front, abnormal tetracycline uptake, and an increase in osteoid. DFO treatment did not significantly change the level of Al in bone, however both DFO treatment and discontinuation of Al reversed towards normal the above described lesions. In conclusion, these studies suggest that DFO and/or discontinuation of Al administration to rats with approximately 30% of renal function greatly improve aluminum-induced osteomalacia.

[Q]: Abstract: From six extended-care facilities, 306 employees responded to a questionnaire on perceived life-style. Most respondents were female, married, and under age 35. The majority had had recent blood pressure checks, seldom missed work because of infections, made time for leisure activities, and felt secure in their jobs. Overall, the percentage of smokers was slightly below the national average, but 45% of the technical employees smoked. Perception of overweight and skipped meals increased with level of education. Consumption of fried foods and sweets decreased with the level of education while fiber intake increased. More skilled and technical employees than professional employees consumed milk products. Less than half of any employee group consumed excessive amounts of coffee or colas. Few study participants consumed alcohol. Very few members of any group consumed meals away from home five or more times per week. Less than half of all employees believed that they received enough exercise; one-third or less exercised regularly. A greater percentage of technical employees than of the other two employee groups expressed interest in improving health through physical fitness and class sessions.

[Q]: Abstract: Intravenous administration of trimethoprim-sulfamethoxazole (TMS) on three occasions resulted in fever, rash, and wheezing in a 30-year-old man with acquired immunodeficiency syndrome with Pneumocytis carinii pneumonia. Pentamidine administration produced fever, severe myositis, and clinical deterioration, and therefore, desensitization to TMS was attempted. This was done with low doses of oral suspension and then intravenous administration during a period of 60 hours. The patient reacted with fevers, arthralgia, and erythema that cleared 4 days after the desensitization was completed. This single case of successful desensitization to TMS in a patient with acquired immunodeficiency syndrome suggests that the oral route may be useful in similar situations when this drug is urgently needed.
