Adrenocorticosteroid injection vs. conservative therapy in the treatment of chalazia

Three methods of treating chalazia were compared in a controlled trial. Group A (conservative therapy of warm soaks and lid hygiene) consisted of six patients with seven chalazia. Group B (intralesional adrenocorticosteroid injection) had five patients with five chalazia. Group C (conservative therapy with intralesional steroid injection) included nine patients with ten chalazia. Success rates after six weeks of follow-up were: Group A: 3 of 7 (43%), Group B: 4 of 5 (80%), and Group C: 9 of 10 (90%). Intralesional steroid injection with or without concurrent conservative therapy was more effective than conservative management alone.     

Incompatibility of contrast agents with intravascular medications. Work in progress

In vitro and in vivo precipitation of iodinated contrast agents when ioxaglate and papaverine are given together has been reported. To verify these reports and to investigate other medications not previously tested, the authors analyzed mixtures of contrast agents and medications in vitro with a light spectrophotometer and observed them for visible precipitates for up to 120 minutes. Previously reported incompatibilities between ionic or low-osmolality contrast media and medications were verified, and several new incompatibilities were discovered. No incompatibilities were found when the drugs tested were mixed with the new nonionic contrast media.
