Can you tell me about the doctor from Malegaon and his nephew's illness mentioned in the Satcharitra?

Chapter 34 tells the story of a degree-holding doctor from Malegaon, in the Nashik district, whose nephew was afflicted with a severe ailment. Despite the doctor's own medical knowledge and the efforts of his physician friends and expert surgeons, no treatment could cure the boy. The illness was a bone-cyst, called Hadyavarn, which was described as a very difficult and extraordinary malady. The family exhausted all native and foreign treatments, and even surgery was unsuccessful, leaving everyone feeling helpless and distressed by the young boy's constant pain.
