• Suggestibility

  Investigation suggested normokalaemia when samples were assayed immediately and therefore ‘pseudo-hyperkalaemia’. Continuing hyperbilirubinaemia and occasional splenomegaly lead to a suspicion of a ‘leaky erythrocytes’. [endocrine-abstracts.org]

  Hemoglobin and hematocrit values are often normal, despite evidence for mild to moderate hemolysis, suggesting that patients are physiologically more anemic than the numbers suggest. [cancertherapyadvisor.com]

  Biological context of STOM There is also evidence that stomatin is linked to the cortical actin cytoskeleton, suggesting a role in cortical morphogenesis of the cell [8]. [wikigenes.org]

  It has been suggested that vitamin E deficiency is the primary stimulus for secondary manifestations of the disease such as neuropathy. [medtextfree.wordpress.com]

  Studies showed that this net K loss from the red cell did not occur at 37degC, and a simple temperature effect was suggested. The presence of this effect in three other unrelated families studied recently by us is illustrated in Figure 1. [the-medical-dictionary.com]

• Seizure

  We describe a child with a stomatocytosis due to a SLC2A1 mutation presenting with hyperkalaemia, liver disease, microcephaly, nystagmus, and seizures. [endocrine-abstracts.org]

• Liver Biopsy

  The child continued to have conjugated hyperbilirubinaemia; a liver biopsy suggested non-specific hepatitis. She developed abnormal movements, nystagmus and microcephaly; EEG was normal but MRI showed periventricular calcifications. [endocrine-abstracts.org]

Hyperkalaemia continued, requiring occasional treatment with Salbutamol, Insulin or Fludrocortisone. Adrenal pathology was excluded. Investigation suggested normokalaemia when samples were assayed immediately and therefore ‘pseudo-hyperkalaemia’. [endocrine-abstracts.org]

What should you tell the patient and the family about prognosis? The natural histories of hereditary stomatocytosis and hereditary xerocytosis are not well understood. [cancertherapyadvisor.com]

Acanthocytes have long, rigid projections and become entrapped and hemolyzed in the spleen, which results in a rapidly progressive anemia of moderate severity, splenomegaly, and jaundice. 4, 13 Spur cell anemia in end-stage liver disease has a poor prognosis [doctorlib.info]
