In both subjects, the clinical picture disclosed renal infarction with transient deterioration of renal function, microhematuria and proteinuria. In 1 patient, a slight, temporary increase in blood pressure was also observed. Both men experienced contralateral relapse 12 days and 7 years, respectively,

Twenty-seven patients diagnosed with either cellulitis (n = 19), chronic osteitis (n = 4), or an abscess (n = 4) were selected. Thirteen patients received tobramycin, 60 to 100 mg iv q. 8 h., plus cloxacillin, 1 gm iv q. 4 h.; seven patients received netihnicin, 40 to 120 mg iv q. 8 h., plus cloxacillin, 1 gm iv q. 4 h.; and seven patients received either cloxacillin, 1.5 gm iv q. 4 h., or cefoperazone, 2 to 4 gm iv q. 12 h. for at least 7 days. Another group of six normal subjects received neomycin, 0.5 gm po q. 6 h. for 7 days. All these subjects had normal thyroid function before antibiotic dosing and none had thyroid function abnormalities. Tobramycin and doxacillin/cefoperazone did not influence thyroid function. Netilmicin decreased the total serum concentrations of triiodothyronine (T,) from 114 ± 9 to 75 ± 7 ng/dl (P < 0.01), probably because of increased clearance, as the T, free fraction increased from 0.43% ± 0.02% to 0.49% ± 0.02% (P < 0.05). Thyroxine (T.) and reverse T, (rT,) levels were not affected. Neomycin decreased T, levels from 104 ± 8 to 92 ± 7 ng/dl (P < 0.05) and the serum concentrations of thyroglobulin from 17.3 ± 2.0 to 11.7 ± 2.0 ng/ml (P < 0.001). Because T. and rT, levels did not change, our results suggest that neomycin may have directly affected the gland. We conclude that some aminoglycosides can alter the disposition of thyroid hormones.

Flow studies as well as delayed scans were performed in all. Especially in primary and metastatic lesions of the posterior fossa, the diagnostic yield was improved by the delayed glucoheptonate (GH) scans. In contrast, no advantage of GH over pertechnetate could be detected in the study of infarcts or other ischemic lesions. Various hypotheses are discussed to explain the observed differences in behavior between the two tracers.

Intrapulmonary shunting was diagnosed with a 99mTc-MAA perfusion lung scan, which showed marked systemic activity. The shunting resolved after liver transplantation. The perfusion lung scan offers an efficient method to screen patients with cirrhosis in whom intrapulmonary shunts are suspected and to follow their progress.
