We note in the diaries of Alexei Nikolaevich and his mother that whenever he recovered from a minor bruising episode -- of which, of course, there were many -- his temperature rose slightly as that amount of blood was reabsorbed. Consider that at Spala the poor boy had displaced a great deal more blood than usual, that his hip joint, his peritoneum (lower) and adjacent areas outside that barrier were inflamed, and that these events alone, exhausting the boy, bringing him near death, leading to a lack of blood to the brain, produced the high fever as the blood was reabsorbed. Delirium in a boy so frail and so exhausted would then be understandable.
There was no mention of any symptoms involving the internal organs in this episode except for the child's heartbeat.
A rising temperature.. no matter how much you want it to be.. is *not*a symptom of haemophilia.
... and a "lack of blood to the brain" caused by his hemorharging elsewhere as an explanation for his delirium?
You do realize, of course, that a "lack of blood to the brain"... which would also mean a lack of oxygen to the brain... would be likely to result in serious neurological damage... which we do not see in Alexei's case.
You mention, too, the known symptoms regarding Alexei's irregular heartbeat. Here again, these symptoms... most notably the symptoms of systolic murmur and/or tachycardia... are known to be symptoms of a platelet disorder. They are not known to be symptoms of a clotting factor disorder.
It's obvious right from the outset that you're still not the least bit interested at all in looking at any of the many other possible blood diseases. You're still determined to make your favourite diagnosis first ... and to then force each and every one of those symptoms to fit that favourite diagnosis.. even if they don't.
That's completely the wrong way to make any diagnosis. You search for every single symptom first.. no matter how small... and only *after* you have tabulated every single symptom do you then start looking for the diagnosis that best fits *all* of those symptoms.
You cannot be sure that you've reached the correct diagnosis unless you can at least try to put that haemophilia word out of your mind for even just a minute or two. You must go through all of the other possibilities first and eliminate them one by one before you can even be the slightest bit certain that you have reached the correct diagnosis.
Only when you have successfully eliminated all of those other possibilities first... can you ever be certain that your favourite diagnosis is also the *correct* diagnosis.
