Mitral insufficiency secondary to mucocutaneous lymph node syndrome. A case report of successful surgical treatment.

A three-year-old girl with mitral regurgitation due to mucocutaneous lymph node syndrome (MCLS) but with normal coronary arteries was treated surgically. Although no definite pathologic lesions causing severe mitral regurgitation except for dilatation of the mitral annulus were found at operation, some minor changes implied focal ischemia of the posterior papillary muscle. A poster-medial annuloplasty was performed without significant residual regurgitation. This is the first patient successfully treated by surgery for mitral valve incompentence due to MCLS. However, additional clinical experiences will be needed to evaluate surgical treatment for this group patients.

Effect of lactic acid bacteria on growth of Staphylococcus aureus.

Cultures of lactic acid bacteria, mostly from foods, were tested for their effect on the growth of Staphylococcus aureus in Trypticase Soy Broth (BBL). Some of the effectors, e.g., Streptococcus faecalis, S. faecium, Lactobacillus lactis, L. brevis, and Leuconostoc mesenteroides, stimulated growth of S. aureus during early hours of growth, especially at higher temperatures of incubation, but most cultures were inhibitory, and some (S. faecium and L. mesenteroides) were even killing by the time of attainment of the maximal phase of growth of the Staphylococcus. Low-temperature meat lactobacilli and Leuconostoc dextranicum inhibited S. aureus at 10, 15, 20, and 25 C throughout its growth. Streptococcus faecalis var. liquefaciens inhibited at these temperatures and at 30 and 37 C, as well. When the ratio of effectors to staphylococci in the inoculum was 100:1, the three enterococci, the meat Lactobacillus, and L. dextranicum prevented the attainment of 5 x 10(6) staphylococci per milliliter at 15 C, and all but the meat Lactobacillus did so at 22 C. A ratio of 1:1 accomplished similar results at 15 C, except that S. aureus was only delayed for 12 hr by S. faecalis. A ratio of 1:100 usually was ineffective. In general, the more effector bacteria there were in the inoculum, the greater was the overall inhibition (or stimulation) of S. aureus. Inhibition was most effective at 10 or 15 C, less so at 20 or 25 C, and least at 30 or 37 C, whereas stimulation during early growth was greater at the higher temperatures. Results with different strains of the effectors and with two strains of S. aureus were similar, for the most part.
