KROK 1 2008 – Question 22 · KROK (Medicine) · Biological Chemistry
A patient consulted a doctor about symmetric dermatitis of open skin areas. It was found out that the patient lived mostly on cereals and ate too little meat, milk and eggs. What vitamin deficiency is the most evident?
- A. Calciferol
- B. Tocopherol
- C. Folic acid
- D. Nicotinamide
- E. Biotin
Hint
Think of a vitamin whose deficiency causes photosensitive dermatitis and is linked to a cereal-based diet poor in animal protein; vitamins mainly affecting bone, blood cells or antioxidant defence do not fit.
