Sickle cell disease (SCD) is a known inherited hemoglobin disorder featured by the presence of sickle shaped erythrocytes in the blood. It can cause cerebrovascular accident (CVA) in adults and children and is responsible for the majority of the strokes in children. Repeated blood transfusion are often required in an attempt to dilute blood thus reducing the risk of vaso-occlusion and stroke in...

An earlier model for the study of rib cage mechanics was modified so that rib deformity in scoliosis could be better represented. The rigid ribs of that model were replaced by five-segment deformable ribs. Literature data on cadaver rib mechanical behavior were used to assign stiffnesses to the new individual model ribs so that experimental and model rib deflections agreed. Shear and tension/co...

OBJECTIVE Rib fractures are the most common injuries resulting from blunt chest trauma. The sensitivity of chest X-rays in showing the rib fractures is limited particularly in those involving the cartilage part of the rib. We investigated the possible rib fractures, those overlooked on chest X-rays, with the use of ultrasonography in minor blunt chest trauma. METHODS A total of 37 patients, w...

a case of sickle cell hb d disease is reported in  young iranian male. the father of whom carried an as sickle cell trait and the mother an ad trait. this disease was diagnosed by hb electrophoresis. agar gel electrophoresis sickling and solubility tests.this is the first case of sickle cell hb d disease reported in iran.

background: hemoglobin s arises is the result of a point mutation (a-t) in the sixth codon on the -globin gene on chromosome 11 causing sickle cell anemia. the presence of fetal hemoglobin in infancy plays a relatively protective role for vaso-occlusive symptoms that are the major contributor for the morbidity and mortality among patients with sickle cell anemia. hydroxyurea, an s-phase-specif...

background: sickle cell disease is a genetic disorder of hemoglobin causing myriad of pathology including anemia. the purpose of this study was to evaluate the baseline values of steady state hemoglobin and packed cell volume as a guide to managing the early recognition of hemolytic crises in sickle cell anemia. methods: a cross-sectional study was conducted among the sickle cell patients atten...
