Between 2009 and 2022, Cornelia “Connie” Jackson had three abnormal mammograms. The nagging worry that accompanied the first two – both turned out to be false alarms – was practically nonexistent by the time she was told last year she needed another follow-up exam.

UNLV Plastic Surgeon Reattaches Roper’s Thumb

Photo: Ben Mays with Dr. Richard Baynosa

Ben Mays held his nearly severed thumb, dangling by a ligament, in his right palm as he rode his 17-year-old quarter horse Bubby out of the South Point Arena and across the parking lot to an ambulance.

He swung the doors open, held out his dangling digit to show the stunned paramedic inside, and handed his horse over to another roper. Then he climbed in and held a bag of ice on his thumb — still shoved inside the white glove he had been wearing — as first responders sped him to University Medical Center in Las Vegas.

Taking care of her children and her husband, preparing their meals and washing their clothes, was the future that would be hers.


Dr. Joseph Thornton on Overcoming Obstacles

Dr. Joseph Thornton, colorectal surgeon

Dr. Joseph Thornton’s road to becoming a physician makes you realize yet again that where there’s a will, there’s a way.

He grew up in a single parent household on the south side of Chicago, the son of an African American bartender who wanted the best for her son. His two aunts, both maids, also lived in the home.

“Combining incomes made the housing affordable,” says the 72-year-old colorectal surgeon who now is an associate professor in the UNLV School of Medicine’s Department of Surgery. “For good times they loved to go to the racetrack and watch the horses run.”


Leaving Them Smiling

For children with rare conditions, UNLV Medicine surgeon restores the ability to show happiness. It’s a procedure that leaves both the patient and the surgeon with smiles on their faces. Surgery to correct the effects of Moebius syndrome – a rare congenital condition that can paralyze a person’s entire face and affect muscles that control back and forth eye movement – can make it impossible for a person to show that sign of happiness that most people take for granted.

UNLV Surgical Oncologist Performs 10-Hour Whipple Procedure

Dr. Randy St. Hill with patient Mary Duda and family

As doctors wheeled 75-year-old Mary Kay Duda into surgery for a pancreatic tumor, she turned to her daughter, Katie, and said, “See you on the flip side.”

Katie Duda, 36, rolled her eyes at the memory, humorous now that her mother is nearing two years cancer-free. At the time, though, the thought of losing her mother was unbearably real.

Mary Kay Duda says she’s one of the lucky unlucky ones. Unlucky in that the tumor growing inside her enveloped the head of her pancreas. Unlucky in that one Las Vegas surgeon declined to operate because the tumor was so large.
