The news item: Recently a news article described a medical device to treat ADHD in children:

FDA signs off on first medical device for treating ADHD in children

As diagnosis rates of ADHD among children skyrocket, a new medical device for the treatment of ADHD could soon hit the market.

The article states that the device called Monarch eTNS is placed on the forehead to send electrical impulses to the brain through the trigeminal nerve.

So, Why Do I Care?? Over 7 million children and 8 million adults have ADHD (attention deficit hyperactivity disorder). ADHD can severely disrupt learning, school activities, social interactions, and job performance, among others. While there are existing treatment options for people with ADHD, any new treatment with fewer side effects is welcome news.

Plain English, Please!!! First, let’s talk about ADHD. Attention deficit hyperactivity disorder is a disorder of the nervous system. Normally, small group of neurons in the brain actively keep behaviors like attention span, interactions with others, and executive function going. When those groups of neurons have a lower

The news item: A recent news item described over a hundred hand sanitizer brands are being removed from store shelves because they may be dangerously toxic:

FDA says to avoid these 130 hand sanitizer products that may not work, or are toxic

Regulators say some of the products contain dangerous levels of methanol, which can lead to blindness, hospitalization and even death.

The article mentions that the toxic ingredient is methanol, and that it may cause blindness.

So, Why Do I Care?? Poisoning by methanol, also called wood alcohol, sickens over 20,000 people each year in the US. These people may become blind in 24 hours, and suffer long-lasting damage to their kidneys and brain. The best prevention is not to consume methanol either by drinking or through contact with skin, such as through hand sanitizers. So, taking hand sanitizers off the shelf is part of the prevention.

Plain English, Please!!! First, let’s talk about what methanol is. Methanol is chemically similar to ethanol, the alcohol in adult beverages. Methanol gets into hand sanitizers when the ethanol ingredient is contaminated with methanol. When ethanol is made by distilleries, sometimes inadvertently methanol is distilled into the product, so then it becomes part of the hand sanitizer.
