Polymeric gastrointestinal MR contrast agents.

Combining either paramagnetic (gadolinium chelates) or superparamagnetic (ferrite) contrast agents with polymers such as polyethylene glycol or cellulose, or with simple sugars such as dextrose, results in mixtures that exhibit improved T1 and/or T2 relaxivity compared with that of the contrast agent alone. It is suggested that the addition of such inexpensive and nontoxic polymers or saccharides may improve the effectiveness and decrease the cost of enteric contrast agents.

Percutaneous penile venoablation for treatment of impotence.

Percutaneous penile venoablation with sclerosing agents and coils was performed in 58 patients. Of 104 ablations attempted, 44 of 51 (86%) transpenile, and 46 of 53 (86.7%) retrograde interventions were technically successful. In 40 patients (69%) erectile function improved (intercourse was possible in 21 without additional measures). Initially improved erectile function deteriorated in 24 patients during follow-up (in an average of 6 months); in 15 of these, intercourse was still possible with injection of vasoactive drugs. In 7 patients, repeat venoablation improved erectile function again. Hot contrast medium was slightly superior to sodium morrhuate as a sclerosing agent. In successfully treated patients, the average decrease in venous leakage was 30 ml/min vs 13 ml/min in treatment failures, with considerable overlap between both groups. Only minor complications were observed. We conclude that percutaneous penile venoablation is technically feasible, and safe. Whether the procedure will have a definite role in the treatment of venogenic impotence, however, still has to be determined.

Bronchoplastic and angioplastic operation in bronchial carcinoma: long-term results of a retrospective analysis from 1973 to 1983.

From 1973 to 1983, 248 bronchoplastic and angioplastic operations were carried out in patients with bronchial cancer. The five-year survival rate of all radically operated patients (stages I and II, n = 108) was 35%. The three-year survival rate in bronchial sleeve resection in stages I and II (n = 46) was 46%. The thirty-day lethality in stages I and II was 9% in bronchial sleeve resection and 5% in combined bronchial and vascular sleeve resections. Indications, surgical technique and complications are discussed.
