Describe the medical situation of the doctor's nephew from Malegaon as explained in Chapter 34.

Chapter 34 of the Shri Sai Satcharitra describes a dire medical situation concerning a doctor's nephew from Malegaon. The young boy was afflicted with a terrible disease identified as a bone-cyst, or Hadyavran, which is described as a most difficult and extraordinary malady. The severity of the condition was highlighted by the complete failure of medical science to treat it. According to the text, the boy's own uncle was a degree-holding physician, and he, along with other expert and intelligent surgeons, tried various treatments. They exhausted all native and foreign remedies and even attempted surgery, but nothing succeeded, and they were left feeling helpless. This comprehensive failure of the medical community, as narrated in Chapter 34, serves to emphasize the miraculous nature of the cure that was later granted through Sai Baba's Udi.
