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.
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.
STUDY DESIGN: This was a randomized prospective follow-up study of pain facility treatment of chronic pain patients with low back pain, with return to work and work capacity as the outcome measures. OBJECTIVES: To determine if after pain facility treatment chronic pain patients "move" in and out of work and in their work capacity; to determine the patterns of "movement;" and to determine the post-pain facility treatment follow-up sampling time points that would maximize the number of chronic pain patients correctly classified according to their final work and work capacity status. SUMMARY OF BACKGROUND DATA: Past research and empiric observation have indicated that chronic pain patients may "move" after pain facility treatment in and out of work and in their job work capacity. Such "movement" can affect the results of outcome studies. METHODS: Two hundred thirty-six consecutive chronic pain patients who fit study selection criteria were followed up at 1, 3, 6, 12, 18, 24, and 30 months after pain facility treatment for determination of work and work capacity status and separated according to the pattern of movement. Stepwise discriminant analysis was used to answer the study objectives. "Movement" in and out of work for these chronic pain patients also was compared with the US general population. RESULTS: Chronic pain patients demonstrated eight work and four work capacity movement patterns. The 24- and 1-month time points predicted final work status correctly for 97.0% and 77.0% of the chronic pain patients, respectively, whereas the most significant predictor for correct work capacity status was the 24-month point. The annual percentage change in employment status for these chronic pain patients was more than in the US general population. CONCLUSIONS: Because chronic pain patients "move" in and out of employment and for work capacity status after pain facility treatment, future outcome studies using these measures will have to consider carefully the impact of "movement" on their results.
