When the three brothers are assigned tasks by a king, the youngest accomplishes the feats with the animals help. ATU 707, "The Dancing Water, the Singing Apple, and the Speaking Bird": one night, the prince (king, tsar, sultan) hears three sisters talking, the youngest promising that, if she were to marry the king, would bear him children (twins, triplets) with wonderful attributes. Her sisters are married to lowly officials or servants of the kings court and, bearing an intense jealousy toward the newly crowned queen, decide to get rid of the royal children. ATU 709, "Snow White": in some regional variants of the tale type, the rivalry isnt between mother and daughter or between step-mother and step-daughter. Instead, it is the heroines older sisters who get jealous over the youngests beauty and charm and conspire to kill her. ATU 780, "The Singing Bone": a person murders their sibling (brother or sister) and buries them in a shallow grave. A tree sprouts from it. Its wood is used to create an instrument (fiddle, violin, flute) that reveals the murder. In literature
A number of Shakespeares plays display the incidences of sibling rivalry. King Lear provokes rivalry among his three daughters by asking them to describe their love for him; in the same play, Edmund contrives to force his half-brother Edgar into exile. In The Taming of the Shrew, sisters Kate and Bianca are shown fighting bitterly. In Richard III, the title character is at least partially motivated by rivalry with his brother, King Edward.
Overhydrated hereditary stomatocytosis
Dehydrated hereditary stomatocytosis (hereditary xerocytosis; hereditary hyperphosphatidylcholine haemolytic anaemia)
Dehydrated hereditary stomatocytosis with perinatal edema and/or pseudohyperkalemia
Cryohydrocytosis
Blackburn variant
Familial pseudohyperkalaemia (not associated with hemolytic anemia)There are other families that do not fall neatly into any of these classifications.Stomatocytosis is also found as a hereditary disease in Alaskan malamute and miniature schnauzer dogs. Treatment
At present there is no specific treatment. Many patients with haemolytic anaemia take folic acid (vitamin B9) since the greater turnover of cells consumes this vitamin. During crises transfusion may be required. Clotting problems can occur for which anticoagulation may be needed. Unlike hereditary spherocytosis, splenectomy is contraindicated. References
