According to the source, what medical efforts were made to cure the doctor's nephew before the family turned to Sai Baba?

The source material for Chapter 34 details the extensive and ultimately futile medical efforts to cure the doctor's nephew of his bone-cyst. The boy's uncle was himself a degree-holding physician, and he, along with his physician friends and expert surgeons, tried a multitude of treatments. The text explicitly mentions that all native and foreign treatments were attempted and that all efforts were exhausted. Even surgery was performed, but it did not succeed in alleviating the boy's suffering. Chapter 34 emphasizes that it was only after these remedies reached their absolute limit with no improvement that the family considered seeking spiritual intervention from Sai Baba.
