A Seattle woman rinsed her sinuses with tap water. A year later, she died of a brain-eating amoeba.Her case is reported this week in the International Journal of Infectious Diseases.The 69-year-old, whose name was not given, had a lingering sinus infection. For a month, she tried to get rid of it using a neti pot with tap water instead of using sterile water, as is recommended.Neti pots are used to pour saline into one nostril and out of the other to irrigate the sinuses, usually to fight allergies or infections.According to the doctors who treated the woman, the non-sterile water that she used it thought to have contained Balamuthia mandrillaris, ?an amoeba that over the course of weeks to months can cause a very rare and almost always fatal infection in the brain.Once in her body, the amoeba slowly went about its deadly work.First, she developed a raised, red sore on the bridge of her nose. Doctors thought it was a rash and prescribed an antibiotic ointment, but that provided no relief. Over the course of a year, dermatologists hunted for a diagnosis.Then, the left side of the woman's body started shaking. She'd experienced a seizure that weakened her left arm. A CT scan showed an abnormal lesion in her brain that indicated she might have a tumor, so doctors sent a sample of tissue for testing.Over the next several days, additional scans revealed that whatever was happening in her brain was getting worse. The mass was growing, and new lesions were starting to show up.Finally, a neurosurgeon at Swedish Medical Center, where the woman was being treated, opened her skull to examine her brain and found that it was infected with amoebae.The US Centers for Disease Control and Prevention rushed the anti-amoeba drug miltefosine to Seattle to try to save the woman's life, but she fell into a coma and died.According to the CDC, most cases of Balamuthia mandrillaris aren't diagnosed until immediately before death or after death, so doctors don't have a lot of experience treating the amoeba and know little about how a person becomes infected.The amoeba was discovered in 1986. Since 1993, the CDC says, there have been at least 70 cases in the United States.As in the Seattle woman's case, the infections are "almost uniformly fatal," with a death rate of more than 89%, according to the doctors who treated her and the CDC.The amoeba is similar to Naegleria fowleri, which has been the culprit in several high-profile cases.In 2011, Louisiana health officials warned residents not to use nonsterilized tap water in neti pots after the deaths of two people who were exposed to Naegleria fowleri while flushing their nasal passages. An official urged users to fill the pots only with distilled, sterile or previously boiled water, and to rinse and dry them after each use."Improper nasal irrigation has been reported as a method of infection for the comparably insidious amoeba," the doctors say in the research paper about the Seattle woman. "This precedent led us to suspect the same route of entry for the ... amoeba in our case."The woman's doctors say they weren't able to definitely link the infection to her neti pot, as the water supply to her home was not tested for the amoeba. They hope her case will let other doctors know to consider an amoeba infection if a patient gets a sore or rash on the nose after rinsing their sinuses.Kristen Maki, a spokeswoman for the Washington State Department of Health, said in an email that "Large municipal water supplies ... have robust source water protection programs" and treatment programs, and she noted that "Well protected groundwater supplies are logically expected to be free of any such large amoeba" such as Balamuthia. 3746

A Pro Football Hall of Fame inductee in 2017, former Arizona Cardinals quarterback Kurt Warner revealed he thought about making a return to the NFL in 2018.During a baseball game in St. Louis on Monday, the 46-year-old Warner said he reached out to a team about possibly returning for the 2018 season, a good eight-plus years after his most recent NFL appearance."I was actually ready to (return) for this coming season," Warner said. "I actually talked to a coach, and my wife said, 'Go for it, I think it would be great.' So, I actually talked to a coach about possibly doing it if they needed someone, but they went out and signed somebody. I don't think they thought I was serious."  700

A study led by researchers from Washington State University found 24 planets that may be more suitable for life than Earth.According to the study, which was published in the journal Astrobiology, the key points the researchers used to describe the "superhabitable" planets were between 5-8 billion years old, wetter, lightly larger, orbit around a particular star, and slightly warmer than Earth.Researchers also noted that some planets orbit stars that change slowly and have longer life-spans than the sun, which means life could thrive on the 24 planets.More than 4,000 exoplanets, which are planets outside our solar system, were researched before researchers settled on the 24 top contenders.None of the 24 planets checked off all the boxes, researchers said.The study stated that the superhabitable planets are located more than 100 light-years away. 864

A vehicle was intentionally driven Friday into three students outside a high school near the southern French city of Toulouse, injuring them, the country's interior ministry said.A driver was arrested after the collision, and the Toulouse prosecutor has been called to investigate, the ministry said.The collision happened outside Saint Exupéry high school, according to CNN affiliate BFM TV.Initial information about the conditions of the injured -- identified by authorities only as Chinese students -- conflicted. The interior ministry said the students were lightly injured; BFM reported that two were in serious condition.Toulouse Prosecutor Pierre-Yves Couilleau said around noon ET that two students remained hospitalized and one had left the hospital.The vehicle accelerated as the students crossed a road, the interior ministry said.The driver has a history of mental illness, the interior ministry said in a statement. The incident doesn't initially appear to be related to terrorism, the interior ministry said.Developing story - more to come  1067
