A 24-year-old woman with shoulder pain had an expanding gas-containing radiolucency adjacent to the glenoid. She had been treated with prednisone intermittently for asthma. After unsuccessful attempts at percutaneous drainage, open exploration was performed with resection of a bursa containing gelatinous material and gas bubbles. The culture grew Neisseria mucosa, an organism that infrequently causes infections and is often categorized as nonpathogenic. This case illustrates that soft tissue gas accumulation is not always ominous but may be due to fastidious low virulence organisms. Appropriate surgical drainage and persistent microorganism cultures are required for definitive diagnosis and therapy.

This paper describes a countywide program to screen and vaccinate dentists, hygienists, and assistants against hepatitis B. Prevaccination screening utilizing anti-HBc as the marker indicating previous exposure to hepatitis B demonstrated positivity rates of 27%, 12%, and 14%, respectively. Suggestions are included for other dental societies that are considering adopting a vaccination program.

A model infection with Candida albicans was established in mice. The animals were pretreated for 1 week with azathioprine, given dexamethasone, and then infected intravenously with Candida. Mortality for the group given Candida infection alone was 20%, 38% when azathioprine was added, and 50% when dexamethasone and azathioprine were given with infection. The titers of Candida in most mice were 10(6) per gram of kidney. The rest of the mice were killed at 30 days. At this time, 16% had no evidence of Candida in the kidneys, but 40% of the mice had titers of 10(6) or more. Mice treated with 5-fluorocytosine had a mortality of less than 4% in 30 days. Five percent of the treated mice killed at 30 days had titers of Candida of 10(6). Therefore, 5-fluorocytosine increases survival in the presence of continued therapy with azathioprine with or without pretreatment with dexamethasone. The survival is associated with decreased titers of Candida in the kidneys.
