10. Breakpoint #4
Unresolved issues: Even with severe vitamin C deficiency, why did the patient bleed (down to a Hct of 14%) into her knee/thigh?
1) Could there have been some "occult" trauma?
2) Are we confident that she doesn't have a congenital bleeding disorder?
3) What about those spherocytes, bili and LDH?
4) Can this all be explained by vitamin K deficiency? How did she become vitamin K-deficient?
