| | Sickle Cell Review for clinicians |
 | | The most common problem for sickle cell patients is the pain episode, a self limiting and reversible pain in the extremities, back, chest, and abdomen. | | | Vocational rehabilitation and outside activities are critical in maximally coping with the chronic pain of sickle cell disease. | | | Centers should have support staffs including patient educators, genetic counselors, psychiatric support, vocational rehabilitation, occupational therapy, physical therapy, and health care providers all working together as a multidisciplinary team to solve the complex medical, psychological, and social problems associated with these diseases. |

| | They concluded that moderate to high levels of fetal hemoglobin (5.4-9.7% to 39.8%) reduced the risk for early onset of dactylics, painful crises, acute chest syndrome, and acute splenic sequestration. | | | Physicians and researchers have sought explanations of the variability associated with the clinical expression of this disease. | | | Its ability to augur future clinical course is insufficiently fine, however, for use as the sole arbiter for high risk treatments such as bone marrow transplantation. |

| | A laboratory should select the approach that is appropriate for its clinical setting and available technology. | | | Since hematology analyzers measure mean cell volume, RBC, and Hb, and determine hematocrit, mean cell hemoglobin, and mean cell hemoglobin concentration, an inaccurate Hb affects the hematology result and those derived from it. | | | One hospital spins a hematocrit and then manually replaces all hemoglobin parameters, such as hemoglobin, mean corpuscular hemoglobin, and mean corpuscular hemoglobin count, with asterisks so those results are unavailable. |
