The procedure involved taking a thin layer of pigmented skin from the persons gluteal region. Melanocytes were then separated out to a cellular suspension that was expanded in culture. The area to be treated was then denuded with a dermabrader and the melanocytes graft applied. Between 70 and 85 percent of people with vitiligo experienced nearly complete repigmentation of their skin. The longevity of the repigmentation differed from person to person. References

In non-diabetic patients there is a modest increase in insulin secretion just before dawn which compensates for the increased glucose being released from the liver to prevent hyperglycemia. However, studies have shown that diabetic patients fail to compensate for this transiently increased blood glucose release, resulting in hyperglycemia. This resulting hyperglycemia is clinically relevant in diabetic patients as its lasting effects can lead to overall poor glycemic control. In Type 1 diabetics hyperglycemia due to the dawn phenomenon can persist despite adequate insulin compensation overnight, while in Type 2 diabetics the dawn phenomenon has been shown to be resistant to treatment with both oral medications and diet modifications. An "extended" dawn phenomenon has also been observed in which the abnormal increase in blood glucose levels continues after breakfast. This prolonged duration is thought to be caused by the compounding effects of absorbing and metabolizing breakfast carbohydrates during this period. Both the dawn phenomenon and its extended period have been shown to be significantly more difficult to control when a patients HbA1c is greater than 7%. Treatment
Management of the dawn phenomenon varies by patient and thus should be done with regular assistance from a patients physician. Some treatment options include, but are not limited to, dietary modifications, increased exercise before breakfast and during the evening, and oral anti-hyperglycemic medications if a patients HbA1c is > 7%. Insulin pumps can also be used to provide continuous subcutaneous infusions and are regarded as the gold standard for managing the dawn phenomenon in type 1 diabetics.
