Correct probable ontology/name errors

These entries should be checked:
o “Meningnitis” → probably “Meningitis”
o “Menopauze” → “Menopause”
o “Pheocytochroma” → probably “Pheochromocytoma”
o “Retinal cell carcinoma” → verify whether this should be “Renal cell carcinoma”
The two highest-priority fixes are therefore: correct the nine Balanced classifications and determine why the 53 diseases lost their CBD/THC evidence. Everything else is secondary.
