Common symptoms include palpitations, faintness and fainting. Diagnosis is generally by 24 hour cardiac monitoring. A permanent pacemaker is indicated for those who are unresponsive to drug therapy.

The sickle has one side of the blade notched, so as always to sharpen with a serrated edge. Cf. Reaping hook, under Reap.

| sickle cell | <haematology, pathology> An erythrocyte that changes from the normal discoid shape to a sickled shape when the oxygen tension is low. The pesence of these cells indicates that the patient is homozygotes for the allele that codes for haemoglobin S and that the patient has sickle cell anaemia. (18 Nov 1997) |
| sickle cell anaemia | <haematology> Disease common in races of people from areas in which malaria is endemic. The cause is a point mutation in the allele that codes for the beta chain of haemoglobin with a substitution of (valine for glutamic acid at position 6. The defective haemoglobin (HbS) crystallizes readily at low oxygen tension. In consequence, erythrocytes from homozygotes change from the normal discoid shape to a sickled shape when the oxygen tension is low and these sickled cells become trapped in capillaries or damaged in transit, leading to severe anaemia. In heterozygotes, the disadvantages of the abnormal haemoglobin are apparently outweighed by increased resistance to Plasmodium falciparum malaria, probably because parasitised cells tend to sickle and are then removed from circulation. Symptoms include joint pain, acute abdominal pain, and ulcerations of the lower extremities. Origin: Gr. Haima = blood (18 Nov 1997) |
| sickle cell anaemia: bone manifestations | <radiology> 8-13% of blacks carry sickling factor, symptoms: chronic ulcers, pain crises, many infections, priapism X-ray findings: deossification due to marrow hyperplasia, decreased bone density in skull with widened diploe, H-shaped vertebrae or fish vertebrae, rib notching, thrombosis and infarction, avascular necrosis, especially femoral head, periosteal treatmentn (bone within bone), secondary osteomyelitis, Staph. Aureus greater than Salmonella, dactylitis = hand foot syndrome, growth effects, bone shortening secondary to diminished blood supply, death less than 40y (12 Dec 1998) |
| sickle cell C disease | A disease resulting from abnormal sickle-shaped erythrocytes (containing haemoglobin C and S) which appear in response to a lowering of the partial pressure of oxygen; characterised by anaemia, crises due to haemolysis or vascular occlusion, chronic leg ulcers and bone deformities, and infarcts of bone or of the spleen.

| sickle cell haemoglobin | <haematology> Haemoglobin S is an abnormal version of the protein haemoglobin. The sixth amino acid of the normal beta chain, glutamic acid, is replaced by valine with gluconic acid. This mutation causes the red blood cell to take on a sickle shape, and is the cause of the sickle cell trait condition (when the individual is heterozygous for this mutant haemoglobin) and the disease of sickle cell anaemia (when the individual is homozygous for this mutant haemoglobin).
