After her 15-year-old son ended up "in critical and life-threatening condition" from an adenovirus outbreak at a New Jersey health care facility, one mother is suing those who she believes allowed her son to end up in the ICU, according to a lawsuit filed Wednesday.Paula Costigan's son, William DelGrosso, was one of dozens of medically fragile children who were infected with the virus beginning in late September at the Wanaque Center for Nursing and Rehabilitation in Haskell, New Jersey.As of Friday, 31 residents have been affected by the outbreak, including 10 deaths, according to the state health department. DelGrosso remains hospitalized.According to the lawsuit, DelGrosso came down with a fever on October 11 and was transferred to the intensive care unit at Hackensack University Medical Center on October 18 with "serious respiratory complications." He is still there now, according to the family's lawyer, Paul da Costa."As a mother, it's hard enough to not have your child under your own roof and have to trust and rely on a facility to care for your child," da Costa said, adding that Costigan "feels as if the facility was trying to hide the fact there was this serious virus spreading like wildfire." 1228

Activated charcoal is the craze in the beauty industry to help get those pearly whites, but at what cost is it taking on oral health?What is activated charcoal?It's not the charcoal used in your backyard barbeque. According to Dr. Todd Shatkin of Aesthetic Associates Centre in Amherst, New York, it's a slightly abrasive powder usually formed by coconut and is used in many different aspects of the health industry. Activated charcoal is an absorptive property, and it's designed to absorb and lift blemishes from teeth.It's used for cleansing, weight loss treatments, and skin care products. Now it's being used for teeth whitening to remove stains. How does it work?A toothbrush is dipped into the powder and is brushed directly onto teeth. The activated charcoal powder removes the extrinsic stains; stains that are caused by wine, coffee and other foods and drink. "Charcoal-based products would be good to remove the surface stain, but it won't internally bleach or whiten the teeth from within," Shatkin said. Is activated charcoal safe to use?Shatkin says yes.He says, to first make sure the product is FDA approved, and check the abrasiveness level. "The enamel is really pretty strong," he said. "If you're in the enamel your probably not going to do any harm to your teeth. But if the patient has worn through the enamel into the dentin, it causes sensitivity and causes discomfort. If you use abrasive materials on the dentin, it will just make things worse."He says, in the end, it all comes down to good oral hygiene and visiting your dentist every three to six months. 1716

About seven minutes after Sacramento police fatally shot an unarmed black man in his grandmother's backyard last week, officers were instructed to mute their body cameras.Stephon Clark, 22, was in the backyard March 18 when two police officers shot him 20 times. Police said they thought he was holding a gun. But investigators say they did not find a weapon at the scene, only a cellphone near the man's body.The Sacramento Police Department on Wednesday released two body camera videos, the 911 call, the helicopter footage and radio traffic from the shooting.In both videos, an officer can be heard saying, "Hey, mute." Directly after, the video goes silent and officers talk among themselves.'It builds suspicion'The shooting has sparked nationwide outrage, with the muting of the body cameras raising questions about the officers' actions. CNN has called and emailed the police department, but has not heard back.Sacramento Police Chief Daniel Hahn told CNN affiliate KCRA that the action has added to the tension after the shooting."Muting is one of those things that we have to take a look at," Hahn said. "Any time there is muting on this camera, it builds suspicion -- as it has in this case. And that is not healthy for us in our relationship with our community."Although the Sacramento Police Department's 2016 body camera policy designates when to activate body cameras, it does not specifically mention when to activate or deactivate sound or audio recordings. Sacramento police, Hahn said, implemented body cameras last year.When can officers deactivate body cameras?The department policy includes 16 instances when a body camera is required to be activated, including vehicle stops and sobriety tests as well as foot and vehicle pursuits.It says employees can deactivate their cameras in some instances, but that's based on their discretion. These instances may occur when officers are having tactical or confidential conversations, when officers are trying to conserve battery life or if a witness or victim refuses to give a statement on camera, according to the policy.Some situations are also based on the officer's judgment, like if a recording would interfere with the officer's ability to investigate or if recording would be inappropriate based on the victim or witness' physical condition and emotional state.However, it's unclear whether deactivating a body camera or muting are different things."I think it's a policy we should look at very carefully and perhaps change entirely," Mayor Darrell Steinberg said during a news conference Friday.Expert: Muting can be justified at timesPeter Bibring, director of police practices with ACLU Southern California, said he's never heard of a department where an officer muted video."Just because an officer thinks this shouldn't be released," that's not a discussion officers should be having, he said. "Officers should not be having personal conversations during the course of an investigation. And that's certainly not what was going on here."Seth W. Stoughton, assistant professor of law at the University of South Carolina School of Law, has done research, presentations and led training on body cameras for the past two years. He said he'd be surprised if muting cameras was illegal, but said he understands why officers would mute their video."They were in a situation where they didn't want a word to be scrutinized," he said.The inclination among officers, Stoughton said, is not to record footage of an officer unwinding moments after a shooting because officers may not phrase things in the right way.However, he said, muting hurts public trust and diminishes police accountability."I think that muting the microphone is wrong," Stoughton said. "By not capturing that information, they may be undermining the investigation."A different perspectiveWhen officers mute body cameras, Stoughton said, the public looks at it from a different perspective."From a public trust perspective, it may have been better to not have a body camera at all than to have it and turn it off halfway through," he said.Body cameras provide information that the public wouldn't otherwise have, but "it's not perfect information," Stoughton said.There is no statewide body camera policy in California, so body camera policies differ from agency to agency, said Jeff Noble, a police practice consultant and a former deputy police chief in Irvine, California."The cameras served the goal that we put body cameras out for, they were on and activated during the chase and during the shooting," Noble said. 4598

Amazon's sales outlook for the fourth quarter was the equivalent of a lump of coal in investors' stockings. Don't worry too much: Jeff Bezos could still deliver a holiday surprise.Shares of Amazon tumbled nearly 10% Friday because investors worried the company's holiday sales could be the worst in years.Amazon (AMZN) is the second-largest retailer in the country, trailing only Walmart (WMT) in annual sales. So a weaker holiday quarter for Amazon could be a bad sign for the overall economy.The Jeff Bezos-led company said Thursday it expected fourth quarter sales to be in a range of .5 billion and .5 billion. That's less than what was expected, and the .5 billion midpoint of this guidance is an increase of just 15% from a year ago.A sales jump of 15% may sound great, but it's pretty tepid for Amazon, which posted a revenue bump of 38% in last year's fourth quarter and increases of more than 20% in both the fourth quarters of 2015 and 2016.The last time Amazon reported a fourth quarter sales increase that was less than 20% was back in 2014, when revenue was up 14.6%. 1097
