* Surgeons have been warned about a new operation for removing cataracts. Researchers from Eye Specialists of Lancaster, Pennsylvania, compared the new technique small-incision phacoemulsification with lens implantation against the more traditional operation. Although the eye seemed stronger following the new technique, researchers are worried by the trend to implant ever smaller optic lenses (JAMA, October 11, 1995).
* Sudden infant death syndrome or cot death may be caused by infections, new research suggests. The possible culprits, isolated by researchers, are the bacteria enterobacteria and staphylococci, upper respiratory infections which tend to occur more in the winter months, and two months after birth when the infant immune system is at its most ineffective (J Clin Pathol 1995; 48: 95-108).
