Three Rhmod siblings were found to have identical Rh: w1, w2, -3, -4, w5 (see article) phenotypes. All had stomatocytic hemolytic anemia. On quantitative hemagglutination studies, as well as on hand tests, all Rh antigens were not equally depressed. Rh17 (Hr0, 'not D') and Rh29 (RH, 'total Rh') were both normal. Rh5 (hr", e) was only slightly depressed. Rh25 (LW) had 50% of the expression expected in normal Rh:-1 cells. Rh1 (Rh0, D), Rh13 (RhA), Rh14 (RhB), Rh15 (RhC), and Rh16 (RhD), were severely depressed. Rh2 (rh', C) was depressed, while Rh7 (rhi, Ce) was absent. Both Rh19 (hrS) and Rh31 (hrB) were depressed. Rh12 (rhG, G) was distinctly depressed, scoring considerably less than rGrG red cells. The unrelated parents, the child of the proposita, and some siblings of each parent showed lessened depression of Rh antigens without displaying the consistent pattern that might be expected from a presumed single suppressor gene. Absence of a consistent pattern may have resulted from differing Rh genotypes, but a frequently observed depression involved Rh14, Rh15, and Rh16 (RhB, RhC, and RhD) without an effect on either Rh1 (RH3 or D) or Rh13 (RhA).

Patients undergoing bone marrow transplant (BMT) are at great risk of infection and sepsis. Long-term central catheters (LTCCs), required for IV therapy, can be a portal of entry for infectious agents. This randomized, prospective study compared two types of catheter dressings in 98 patients undergoing BMT: a dry sterile gauze dressing (DSGD) changed daily and a transparent adherent dressing (TAD) changed every four days. Study outcomes included incidence and severity of local and systemic complications, patient assessment of comfort, and calculation of nursing time. One case of catheter-related infection occurred during the study. No significant differences existed between the two dressings in the incidence of positive skin cultures or local complications with the exception of skin irritation. The TAD caused less skin irritation, was preferred by patients, cost less, and required less nursing time. The findings indicate that TADs provide a safe, comfortable, and cost-effective alternative to DSGDs for patients undergoing BMT and receiving antibiotic support during aplasia.
