Can you tell me about the doctor from Malegaon whose nephew was cured by Sai Baba's Udi?

Chapter 34 of the Shri Sai Satcharitra narrates the story of a degree-holding doctor from Malegaon whose nephew suffered from a severe bone-cyst, also known as Hadyavarn. Despite the doctor's own expertise and consultations with other expert surgeons, all medical treatments, including native, foreign, and even surgery, failed to provide any relief. The boy was in immense pain. As a last resort, after hearing of the great saint Sai Maharaj in Shirdi, the parents went to seek his help. They explained their plight to Baba, who, being the embodiment of compassion, reassured them. He gave them Udi and instructed them to smear it on the wound, promising them they could now be worry-free.
