What kind of diseases can Sai Baba's Udi cure? Can you give an example from the Satcharitra?

According to the Shri Sai Satcharitra, Udi possesses a profound glory and can cure even terrible and seemingly incurable diseases. Chapter 34 provides a powerful illustration of this through the story of a doctor's nephew from Malegaon. The boy suffered from a bone-cyst, also known as Hadyavran, which is described as a most difficult and extraordinary malady. Despite the efforts of his uncle, who was a doctor, and other expert physicians and surgeons who tried all native and foreign treatments, the disease showed no improvement. As this chapter narrates, it was Sai Baba's Udi that was prescribed as the ultimate remedy for this ailment that medicine could not conquer.
