(Press-News.org) As the use of e-cigarettes has risen dramatically in the United States in recent years, so have calls to poison centers about them. Yet many parents who use e-cigarettes - or "vape" - aren't aware of the dangers to children, according to a new study at Washington University School of Medicine in St. Louis.
The devices are used like typical cigarettes but instead of tobacco, they vaporize a liquid mixture of nicotine, glycerin and glycol ethers. The liquid form is flavored, which appeals to children. If ingested, a teaspoon of this "e-liquid" can be lethal to a child, and smaller amounts can cause nausea and vomiting that require emergency care. Exposure to skin also can sicken children.
"These are largely avoidable risks, but because e-cigarettes are relatively new, many people - including pediatricians - aren't aware of the dangers or the steps that should be taken to protect children from them," said first author Jane Garbutt, MD, a professor of medicine and of pediatrics at the School of Medicine.
The research is published Aug. 25 in the journal Academic Pediatrics.
For the study, 658 parents and guardians at 15 pediatric clinics in the St. Louis area completed surveys about their knowledge and use of e-cigarettes. Almost all parents knew about e-cigarettes: 1 in 5 had tried them, and 1 in 8 said a family member regularly smoked e-cigarettes. In two-thirds of the homes where children were exposed to e-cigarettes, they also were exposed to regular cigarettes.
The researchers found that 36 percent of the e-cigarette users neither locked up e-liquid bottles nor used childproof caps. Such caps, while required in Europe, are not mandated in the United States. E-liquid most commonly was stored in a drawer or cupboard (34 percent), a purse or bag (22 percent) or on an open counter (13 percent), the study showed.
"Three percent of the people in our study said a child of theirs had tried to drink the e-liquid," Garbutt said. "The easiest way to lower risk is to store e-liquid out of the reach of children. Open counters and shelves, unlocked drawers, and purses and bags aren't safe storage places."
Last year, a toddler in New York died after ingesting liquid nicotine intended for use in an e-cigarette.
The researchers were surprised that e-cigarettes were used in so many homes and were concerned about the safety risks to children from unsafe storage of e-liquid. Yet, few parents were aware of these risks.
In the study, only 15 percent of e-cigarette users reported that they had told their pediatricians they were using the devices. Six percent of users said the doctors had discussed with them the use and safe storage of e-cigarettes.
"We strongly encourage pediatricians to ask parents about nicotine use, including e-cigarettes, and to discuss the risks of exposure," Garbutt said. "Ingestion is bad, of course, but even skin exposure to e-liquid can harm children."

Less than 10 per cent of paediatric patients who suffer a cardiac arrest outside of the hospital survive. There are many factors which can influence survival rates; paramedic care is one of them.
Thanks to the advanced training of paramedics, today, they can spend more time on the scene doing CPR or providing medical care including administering intravenous fluids and medications. However until now, it has not been known if the length of time spent on the scene and onsite medical interventions by paramedics are associated with improved survival for paediatric patients.

Inflammatory bowel disease (IBD) has been historically underdiagnosed in African-Americans and is increasing in frequency.
Several gene variants for IBD in whites are key risk factors in African-Americans.
Also important are unique African ancestral variants that cause protection against IBD.
In African-Americans, as in whites and Asians, the dominant region for ulcerative colitis genetic risk in is the human leukocyte antigen region, a major determinant of immune regulation.

NEW YORK, NY (August 25, 2015)-- Klinefelter syndrome is the most common disorder of the male sex chromosomes, yet is rarely diagnosed in children. A new assessment tool is being developed by researchers at Columbia University Medical Center (CUMC) to help pediatricians detect the physical traits of the syndrome. The tool could pave the way for early interventions that prevent and treat a range of physical, psychological, social, and cognitive impairments. The study was published in The Journal of Pediatrics.
According to lead author Sharron Close, PhD, boys with Klinefelter ...
In the biochemical game of genetics, it was thought that the proteins controlling gene regulation in animals were either spectators or players.
But in research appearing in the current issue of eLife, Michigan State University researchers found that spectator proteins are actually practicing up for the big game. They discovered that the proteins are biochemically interacting with thousands of regions of the genome to change the structure of chromosomal material, although only few of them actually are able to change gene expression.
"The previous thinking was that these ...
Cities are well known hot spots - literally. The urban heat island effect has long been observed to raise the temperature of big cities by 1 to 3°C (1.8 to 5.4°F), a rise that is due to the presence of asphalt, concrete, buildings, and other so-called impervious surfaces disrupting the natural cooling effect provided by vegetation. According to a new NASA study that makes the first assessment of urbanization impacts for the entire continental United States, the presence of vegetation is an essential factor in limiting urban heating.
Impervious surfaces' biggest ...
The greater a country's gender equality when it comes to employment, the higher the overall homicide rate, according to a Baylor University study of 146 countries.
"The finding does not mean that gender equality in employment increases homicide rates, but there is a correspondence," said sociologist Katie Corcoran, Ph.D. "What remains uncertain is the 'why' behind this relationship, although prior research suggests it may be due to threatening male status.
"The research findings are significant because they show that gender inequality does not only affect women," she ...
Genetic findings support observational evidence that lower vitamin D levels are associated with increased risk of multiple sclerosis, according to a new research article by Brent Richards, from McGill University, Canada, and colleagues published this week in PLOS Medicine.
Multiple sclerosis is a debilitating autoimmune disease that affects the nerves in the brain and spinal cord. There is no known cure for multiple sclerosis and it usually presents between the ages of 20 and 40 years. While some observational evidence suggests there may be a link between lower vitamin ...
A new modeling study appearing this week in PLOS Medicine supports consideration of vaccination campaigns using a single dose of cholera vaccine versus campaigns using the recommended two doses given two weeks apart.. Justin Lessler and colleagues, of Johns Hopkins Bloomberg School of Health, Baltimore, Epicentre, Paris and Médecins Sans Frontières, Geneva focus their modelling analyses on comparing the number of lives that could be saved by adopting a single vaccine dose, which could be more rapidly administered to more people than the internationally licensed ...
An oral cholera vaccine that is in short supply could treat more people and save more lives in crisis situations, if one dose were dispensed instead of the recommended two, new Johns Hopkins Bloomberg School of Public Health research suggests.
More than 1.5 billion people around the world are at risk for cholera, a severe diarrheal illness caused by bacteria linked to poor water and sanitation. It is a major killer worldwide, causing an estimated two to three million cases and 100,000 deaths each year, primarily in developing nations.
A relatively new vaccine -- internationally ...
Evolutionary theory says mutations are blind and occur randomly. But in the phenomenon of adaptive mutation, cells can peek under the blindfold, increasing their mutation rate in response to stress.
Scientists at Winship Cancer Institute, Emory University have observed that an apparent "back channel" for genetic information called retromutagenesis can encourage adaptive mutation to take place in bacteria.
The results are scheduled for publication in PLOS Genetics on Tuesday, August 25.
"This mechanism may explain how bacteria develop resistance to some types of antibiotics ...
