Systemic argyria.
A 74 year old man presented with signs and symptoms of mild cardiac failure. His face and chest were severely discoloured, which was thought to be due to cyanosis. He deteriorated and died of bronchopneumonia. At post mortem examination multiple organs, including the skin, showed silver pigment deposition; he also had a gastric malignant neuroendocrine tumour. He gave no history of contact with...

متن کاملCyanosis without Sulf- or Methemoglobinemia in Patients Receiving Sulfanilamide Treatment.
Cyanosis is very frequently observed in patients receiving sulfanilamide therapy. This cyanosis seems to be almost generally attributed to sulfhemoglobinemia or methemoglobinemia, though few writers have actually identified these derivatives in cyanotic patients. Colebrook and Kenny (1) in an early report, stated that three of thirty-eight patients developed sulfhemoglobinemia, as shown by spec...
متن کاملStudies on Cyanosis
These data prove that abnormally high oxygen unsaturation of the blood is a cause of cyanosis. The fact that the lowest value of oxygen unsaturation (in the venous blood) associated with cyanosis is about 8 volumes per cent seems to indicate that this amount of reduced hemoglobin is the lowest capable of producing a cyanotic color. We shall later discuss this point more in detail. Table III sho...
متن کاملDesigning preterm neonatal cyanosis simulation
Premature newborns have a lower survival expectancy than full term neonates. Determining their possible health risks is crucial. Training for health risk assessment is one of the factors that might help in lowering the mortality of premature neonates. The paper describes the design approach to develop a premature neonate simulator showing colorization of the facial skin to simulate cyanosis to ...
