The results of a study on color vision capacity performed with a view to further analyzing glaucomatous dyschromatopsia are reported. The Farnsworth-Munsell 100-hue test was used in a population of 52 subjects (104 eyes) with daylight fluorescent lighting and low-tension halogen lighting. Photocolorimetric observations with each type of lighting were made. It was found that halogen lighting increased the glaucomatous subjects' mean score, the number of dyschromatopsia and the number of blue-yellow dyschromatopsia axes. The authors conclude that halogen lighting is preferable for the Farnsworth-Munsell 100-hue test in glaucoma and confirm the predominance of blue-yellow dyschromatopsia axes in glaucoma.
Choices about referrals, tests, and prescriptions offer physicians many opportunities to reduce health care costs. Some commonsense measures are described, and the principles to which cost-effectiveness analyses should adhere are explained.
Living-related donor liver transplantation (LDLT) is an accepted approach to pediatric liver transplantation. Parental donation imposes a significant risk of chimerism with graft-versus-host disease (GVHD) because donors homozygous at all HLA loci (1.6% of the population) present no mismatched HLA antigens to be recognized by their offspring's immune system. The case of a 9-month-old who underwent LDLT with her 23-year-old HLA-homozygous mother as a donor demonstrates the consequences of this occurrence. The patient developed GVHD with aplastic anemia; the patient's nucleated peripheral blood elements were shown to be entirely derived from the donor. Later, after some marrow recovery, the patient's circulating lymphocytes had a donor origin, while the marrow-derived neutrophils had a recipient origin. The patient suffers from chronic GVHD and debilitating skin disease several years posttransplant. Our current protocol calls for HLA typing to eliminate parents who are homozygous at all HLA loci as donors of hepatic allografts to their children.
