Nutritional Deficiency Dermatoses

The presentation discusses nutritional deficiency dermatoses, emphasizing the importance of recognizing skin signs that may indicate underlying nutritional deficiencies. The speaker shares clinical cases illustrating conditions such as rhinoderma due to vitamin A deficiency, pelagra due to vitamin B3 deficiency, and scurvy from vitamin C deficiency, among others. Each case highlights risk factors, symptoms, and diagnostic approaches, along with recommended treatments. Various dietary habits, especially fad diets, are analyzed for their potential to cause deficiencies in essential nutrients like vitamins A, B12, C, and D, as well as minerals like zinc and calcium. The speaker encourages dermatologists to assess patients' dietary practices to identify possible nutrient inadequacies that could be affecting their skin health and overall well-being. Key findings include that deficiencies can exist concurrently and that supplementation can often address these issues. The talk concludes with an emphasis on awareness of nutritional deficiencies in clinical practice to improve patient outcomes.
