Septic arthritis of the glenohumeral joint. Unique clinical and radiographic features and a favorable outcome.

Seven patients (eight shoulders) with sepsis of the glenohumeral joint were studied clinically and radiographically. Despite the advanced age of the patients, the presence of gram-negative organisms, and multiple risk factors in each patient (including serious chronic underlying diseases), needle drainage and parenteral antibiotics were all that were required for successful management, provided early diagnosis with prompt institution of antibiotics and drainage occurred. Contrast arthrography safely guided therapy and revealed rotator cuff tears in four of six shoulders as well as frequent extra-articular extensions of the disease. A nonleukemic patient with Aeromonas hydrophilia sepsis and arthritis is reported who survived with eradication of infection and preservation of joint function. A poor prognosis for shoulder sepsis is not substantiated.

Effect of endotoxemia on contrast media reactions.

Since complement activation is sharply temperature-dependent, we have examined the effects of fever produced by a very small dose of endotoxin on contrast media lethality in rabbits. After the injection of 8.2 ml/kg of 52% methylglucamine iodipamide, a group of rabbits exhibiting an average temperature elevation of 1.5 degrees C had a 100% mortality rate. This was contrasted to a 30% mortality in control rabbits receiving contrast alone, and no mortality in rabbits receiving endotoxin alone. The rabbits with fever and increased mortality exhibited increased activation of serum complement. From this preliminary data it appears that caution should be observed in performing a contrast examination in a patient with endotoxemia and/or a fever.

Clinical effects of a stannous fluoride mouthrinse on plaque.

The purpose of this 3-week, double-blind study was to determine the effect of a stannous fluoride-containing mouthrinse on existing and developing dental plaque. A total of 55 subjects (mean age = 31.42 yrs.) received a professional prophylaxis in randomly assigned contralateral quadrants and were then stratified into two balanced groups based on screening plaque scores: one group (27 subjects) used the placebo rinse, the second group (28 subjects) used the test mouthrinse (0.63% diluted to 0.1% stannous fluoride). Plaque index (PI) and stain index (SI) were scored at baseline, week 1 and week 3. Gingival inflammation (GI) was monitored as a measure of product irritancy potential. The PI for the stannous fluoride rinse was significantly lower than the placebo, (p < 0.0001), for both prophied and unprophied sites with an average reduction of 29% at week 1 and 28% at week 3. There was no statistically significant difference between the presence or absence of prophylaxis. Plaque indexes for both stannous fluoride and placebo showed significant reduction (p < 0.0001) compared to baseline in all sites. Differences in staining potential between stannous fluoride and placebo were not significant (p > 0.05) at any time during the study. The stain index for both stannous fluoride and placebo showed a non-significant increase from baseline in the prophied and unprophied sites. No irritancy was noted, although a trend towards lower GI scores was observed at 3 weeks for the stannous fluoride group.(ABSTRACT TRUNCATED AT 250 WORDS)
