Hemoglobin Setif produces pseudosickling of red cells in vitro; the nature of the process and the conditions that "trigger" it are unknown. Studies of red cells, hemolysates, purified hemoglobin solutions, and artificial mixtures of Hb A and Setif suggest that pseudosickling is produced by intracellular crystallization of insoluble hemoglobin.

A Turkish Cypriot family was investigated for suspected heterozygous sickle cell disease, which had been reported in a maternal branch of the family resident in England. Two maternal grandparents were of African Negro origin. Pseudosickling was noted in members of the family who were found to have an abnormal hemoglobin fraction. This abnormal fraction(More)

A survey of Sydney Hospital staff members for Au antigenaemia was performed during a six-month period in 1972. Nine hundred and forty-six staff members were tested by the immunoelectroosmophoresis (IEOP) method and two asymptomatic chronic carriers were detected. Subsequently, it has been hospital policy to test all new staff members. Eight hundred and(More)
BACKGROUND Sagittal displacement in patients with end stage ankle arthritis has been described as the tibiotalar ratio (TTR). Yet the incidence, distribution and predictive factors of talolisthesis are unknown. METHODS The radiographs of 470 cases of ankle arthritis were compared with a control group of 49 normal ankles. The TTR was measured for both(More)
Tibiocalcaneal fusions (TCF) present a challenge to Foot and Ankle Surgeons, as they are often performed in the setting of severe deformity or infection. We present a novel peg-in-hole technique for TCF supplemented by Ilizarov external fixation performed on 52 patients. Indications for this procedure include Charcot neuroarthropathy, infection, avascular(More)
