|Sarah Murnaghan Fights the Under-12 Rule|
Sarah Murnaghan, a 10-year-old Pennsylvania girl dying of cystic fibrosis, received a double lung transplant in June after her family successfully sued to make her more likely to get lungs from an adult donor.
The Murnaghans argued that a so-called Under-12 Rule discriminated against children on the lung transplant waiting list, and the saga ultimately convinced the Organ Transplantation and Procurement Network to alter its policy slightly to allow exceptions in certain circumstances.
Sarah, now 11, returned home from the hospital in late August. She even got to play in the snow in early December.
|Mississippi Baby's HIV Disappears|
An unnamed Mississippi baby stunned doctors when her HIV infection seemed to disappear after five months off treatment.
Dr. Hannah Gay, a University of Mississippi Medical Center pediatric HIV specialist, and her colleagues announced the finding in March and concluded that it was the result of early and aggressive therapy with antiretroviral drugs.
They administered the extra drugs when the girl, now a toddler, was 30 hours old, before confirming her HIV-positive status.
Experts warned this kind of treatment wouldn't work for everyone, and that only time would tell whether the girl's HIV returns.

|Porn Industry Shuts Down Over HIV|
The porn industry shut down three times this year after five performers reportedly became infected with HIV.
Porn actor Cameron Bay was the first performer to come forward, prompting the first moratorium on filming in September. Then, her boyfriend, porn star Rod Daily, announced that he, too, recently received an HIV diagnosis. The couple has since spoken out against unsafe industry practices, and said it's time to mandate condoms.
In December, an industry trade group reported a fifth HIV-positive performer, resulting in a third shutdown.
|Mega-Church Tied to Measles Outbreak|
An outbreak of the highly infectious measles virus had Texas health officials puzzled in August, considering there's an effective vaccine to prevent it.
They soon learned, however, that the 20 cases were tied to a mega-church whose founder suggested vaccines were dangerous to children because they could cause autism. The televangelist Kenneth Copeland has since preached immunizations to his congregants.
