Unfounded Fears of the HPV Vaccine May Have Grim Consequences

Just Breathe

Emily is an emergency dispatcher, yet work is the only place where she always feels calm. Sometimes, when Emily (not her real name) walks her dog on the sidewalks of her Pittsburgh neighborhood or gets ready to leave her home to run errands, she feels a spell of dizziness. Then…

Breaking the Silence

At age 35, after a long labor and birth of her second child, Lisa (not her real name) developed urinary incontinence. She kept it a secret even from her then-​husband, a military man. “He never knew. It’s humiliating… Even bringing it up to the Army doctors was embarrassing. They said,…
