Intraoperative floppy iris syndrome occurred in approximately 2% of a cataract surgery population and appeared to be caused by tamsulosin, a systemic sympathetic alpha-1A antagonist medication that is the most frequently prescribed medication for benign prostatic hypertrophy.

The Childrens Cancer Study Group (CCSG) undertook a study (CCG-823F) to test the feasibility of administering continuous infusion doxorubicin (CI DOX) and cisplatin (CDDP) in patients with unresectable or incompletely resected hepatoblastoma (HB) or hepatocellular carcinoma (HCC). Chemotherapy consisted of CI DOX 20 mg/m2/d for days 1 to 4 and CDDP 100 mg/m2 on day 1 followed by a 21-day rest period. Second-look surgery was performed after the administration of four chemotherapy courses. Forty-seven (47) assessable patients were entered on study, 33 with HB and 14 with HCC; of these, 34 (26 HB and eight HCC) completed the initial four courses of chemotherapy. Of the 26 HB patients, 25 were evaluated as responding to chemotherapy before the scheduled second-look procedure and were considered surgically resectable at that time. Surgery was performed on 22 patients; three patients refused the second-look surgery. Nine patients had no evidence of residual malignant disease, seven underwent surgical resection of remaining tumor, four were left with microscopic residual disease, one had a partial resection with gross tumor left behind, and one remained unresectable. Nine HCC patients completed four chemotherapy courses. Eight patients achieved a partial remission and second-look surgery was attempted on seven. Only two had all malignant disease removed at the second procedure. Data from 225 courses of chemotherapy were evaluated for toxicity. Neutropenia (absolute granulocyte count less than 500/mL) was observed in 68 courses, and five of these episodes were associated with sepsis. Severe mucositis was documented in 21 courses, and hypomagnesemia (magnesium less than 1.2 mg) was noted in 30 patients. Two patients developed decreased left ventricular shortening fraction, which resolved when chemotherapy was discontinued. In summary, CI DOX plus CDDP is a well-tolerated and effective regimen in inducing surgical resectability in HB patients who are unresectable at diagnosis and significantly improves survival for this group of patients to 66.6%.

The combination of reported missed doses and pill counts was a significant predictor of compliance as measured by electronic monitoring. Electronic monitoring caps provided useful information only when they were used appropriately. Asking clients about missed doses and performing pill counts are the most practical assessments of compliance in practice.
