PROBLEM: Paragraph: The Food and Drug Administration approved Medtronic's CoreValve system based on U.S. clinical trials in which it was shown to be safe and effective while demonstrating low rates of stroke and valve leakage, the company said. CoreValve, in which the replacement valve is threaded into place through an artery using a catheter, spares patients chest-cracking surgery. The system has been available since 2007 in Europe, where it is not uncommon for medical devices to win approval several years ahead of the United States. Claim: U.S. FDA approves Medtronic heart valve replacement system.

SOLUTION: Medtronic Inc's non-invasive systems for replacing diseased heart valves won U.S. approval for use in patients deemed too frail to endure traditional open heart surgery, the U.S. medical device maker said on Friday.

PROBLEM: Paragraph: Once an illness is added to the list of approved conditions, the board cannot remove it because state law does not give the board authority to do so, according to board spokeswoman Tessie Pollock. Petitions will be reviewed early next year. AIDS, Alzheimer's disease, and Amyotrophic lateral sclerosis, or ALS, are among the 21 current approved illnesses, along with cancer, epilepsy, glaucoma and Parkinson's disease. Earlier this year the board rejected petitions seeking to add anxiety and autism spectrum disorders as qualifying conditions. The board will for the first time open up a public comment period, beginning after its Jan. 8 meeting, said executive director Stephanie Louka. Final decisions on new accepting conditions would come after several months. ___ This story was first published on Dec. 25, 2019. It was updated on Dec. 27, 2019, to correct the name of the State Medical Board of Ohio spokeswoman. She is Tessie Pollock, not Tessa Pollock. It was also updated to clarify that the board says state law does not give it the authority to remove conditions from the list of approved conditions for which doctors can recommend medical marijuana to patients. Claim: Board to consider new conditions for medical marijuana use.

SOLUTION: The state Medical Board is accepting new petitions through the end of the year from those seeking to add illnesses as qualifying conditions for physicians to recommend medical marijuana to Ohio patients, cleveland.com reported.

PROBLEM: Paragraph: The department cited a Centers for Disease Control and Prevention study showing that the number of people across the U.S. being infected by diseases from mosquitoes, ticks and fleas has tripled from 2004 to 2016. Reported cases have increased in Illinois by 58 percent in that same time period. Ticks and mosquitoes can carry diseases causing mild to severe illness, and even death in some cases. The most common mosquito-borne illness in the state is West Nile virus, which can cause paralysis or death in severe cases. The department recommends people use insect repellent containing DEET to repel the insects. Claim: Illinois illnesses from insect bites increased by 58 percent.

SOLUTION:
The Illinois Department of Public Health is warning the public to take precautions against tick and mosquito bites, saying reported cases of infections have increased over the past decade.
