Chiari pelvic osteotomy in children and young adults.
We conducted a follow-up study of twenty-four patients who had been treated with a Chiari osteotomy at the Alfred I. duPont Institute between 1966 and 1981. The length of follow-up ranged from three to twenty years, and the age at operation ranged from ten to twenty-three years. The indication for the operation was either painful dysplasia or gross instability of the hip. Twelve patients had had congenital dislocation of the hip; six, poliomyelitis; three, cerebral palsy; and three had had another disorder. A good or excellent result was obtained in twenty-one of the twenty-four patients. Preoperative pain and antalgic gait were consistently improved. In twenty-one patients, the osteotomy had to be displaced more than 50 per cent to provide adequate coverage of the femoral head, and bone-grafting was necessary at the site of the osteotomy to prevent problems with healing.

Age-specific incidence of chickenpox.
Because licensure of a chickenpox (varicella) vaccine is likely soon, it is important to ascertain the age-specific incidence of chickenpox. Increasing vaccine coverage and a resulting decrease in transmission may result in an accumulation of susceptible adults, followed by a shift of incidence into those older age groups in future years. Valid baseline age-specific incidence will make it possible to detect this phenomenon. Two studies were conducted in Kentucky to assess age-specific incidence of chickenpox. The first assessed chickenpox occurrence in two consecutive school-year cohorts of children from a geographically representative sample of Kentucky primary schools. The second gathered information from household members of those persons interviewed in the Behavioral Risk Factor Surveillance System telephone survey. The age-specific rates are remarkably similar between studies. Rates peak during the preschool and kindergarten years (ages 3-6). Approximately 20 percent of children remain susceptible to chickenpox after age 8 in both studies. The results from these two surveys will be valuable baselines for comparison with findings in incidence studies that will be performed after vaccine licensure.
