Swabs were taken for culture from the periurethral area and urethral meatus in 124 uncircumcised and 60 circumcised boys. Proteus mirabilis was grown from 28 (22.6%) swabs from uncircumcised boys and from only one (1.7%) swab from circumcised boys. This supports the idea that the prepuce may be the source of proteus urinary tract infection.

Comparative effects of SCH 19927 and timolol on intraocular pressure of conscious rabbits and relative systemic beta-blockade resulting from topical administration.

SCH 19927, the RR isomer of labetalol, has been shown to possess beta-blocking and vasodilator properties. It was compared to timolol for ability to lower intraocular pressure (IOP) in conscious rabbits. Its potential for systemic beta-blockade after topical administration was also assessed. Dose-related reductions in IOP followed topically applied SCH 19927 (0.1-1.0%). Timolol in concentrations less than 0.5% was not effective in lowering IOP. Timolol (0.1 and 0.5%) strongly inhibited tachycardia induced by iv isoproterenol. A 1.0% concentration of SCH 19927 was less effective than 0.5% timolol in inhibiting the isoproterenol-induced tachycardia; 0.1% SCH 19927 caused only minor inhibitory actions. Thus, not only is SCH 19927 at least as potent in lowering IOP in conscious rabbits, its topical administration results in less systemic beta-blockade than does timolol.

En bloc resection of primary rib tumors in 40 dogs.

Single or multiple rib resection was performed in 40 dogs for the treatment of primary osteosarcoma or chondrosarcoma. The resulting thoracic wall defect was closed with polypropylene (12 dogs), primary muscle flap (16 dogs), diaphragmatic advancement (10 dogs), or a combination (2 dogs). Few immediate (less than 2 weeks) postoperative complications were observed. Twenty dogs with osteosarcoma had a median survival time of 3.3 months (range, 0.5 to 23 months), with a 20% 6-month survival time. Metastases occurred in all the dogs. Fourteen dogs with chondrosarcoma followed up longer than 2 weeks had a median survival time of 10.7 months (range, 0.5 to 36 months) with a 64% 6-month survival time. Eight dogs developed metastases, five died from concurrent disease, and one dog is alive. Dogs with chondrosarcoma survived significantly longer than dogs with osteosarcoma. Survival time was not related to tumor size or number of ribs resected.
