KAMPALA, Uganda (AP) — The American neurosurgeon leaned in to take a selfie with his patient, chuckling with excitement when she raised her hands. That was a good sign the day after Michael Haglund and his Duke University team opened the patient’s skull to remove a tumor.

The operation was one of many complex, life-saving surgeries the team performed for a week on Ugandan patients who otherwise had little hope of survival.
