On March 13, the FDA was alerted to five cases of acute non-viral hepatitis (resulting in acute liver failure) in infants and children that occurred in November 2020 with an unknown cause reported to the Southern Nevada Health District. All five patients had been hospitalized but have since recovered. All patients were reported to have consumed “Real Water” brand alkaline water. These patients came from four different households. Five additional people, two adults and three children, from two of the four households were reported to have experienced other symptoms as well. Less severe symptoms included fever, vomiting, nausea, loss of appetite, and fatigue.

2,4-Dinitrophenol (DNP) is a chemical that is not approved for weight loss. It is a classic case of efficacy, but without safety in the setting of weight loss. This setting of weight loss can be prone to chemical misuse, further exacerbating understanding in human systems. Christopher is one of 2 - 3 cases documented in literature to have survived an accident with DNP for weight loss. As of 2021, one organization has permission from the US FDA to investigate DNP in some neurodegenerative disorders. These are rare diseases with limited standards of care, therefore extenuating circumstances to find anything that could potentially improve patient outcomes.

Licorice candy has glycyrrhizin which increases cortisol (stress hormone) levels in the body. This causes hypokalemia. Hypo- low. Kal- kalium (potassium). emia- presence in blood. Potassium signals muscle relaxation. Low potassium, low relaxation. Heart can't relax, then it stops.  Real licorice candy is not easy to get in the United States. It's not at big chain grocery stores. Most of what you can buy from the big brands is licorice flavored, and won't do this.

Heatstroke is a serious problem and the heatwaves that cause it, claim more lives on average than any other weather event in USA. While generally thought to affect the elderly and the very young, it can affect people of all ages, not just because of the heat in the environment (classic heatstroke) but also because of activity (exertional heatstroke). The problems caused by heatstroke sometimes happen but don't appear clinically, like GI ischemia.

Bitcoin is a decentralized cryptocurrency that's used in peer to peer transactions. This happened in 2011 when individual people could still mine coins, but now, miners are usually pools or in large facilities in places that have cheap electricity and cool climate to save on computer cooling costs.

Methanol-contaminated hand sanitizer has been on sale in the USA during COVID-19 pandemic. The FDA has issued a warning against this, and have listed the brands. Most stores that are selling these brands have pulled them from shelves.

Methanol is a toxic alcohol that can cause blindness. Its antidote is ethanol, which is the alcohol that people drink casually, however management needs to be done by a healthcare professional, as methanol hangs around in the body for several days.

The case presented here predates the pandemic by almost 20 years. However, methanol skin absorption has been identified as an industrial work hazard since the early 20th century.

Chubbyemu case: https://youtu.be/UrbylXMU8Mw 

Most snowglobes are just made of water, but some can contain ethylene glycol. Most of those usually don't contain enough ethylene glycol to cause damage, but keep the word "usually" in mind. A homemade snowglobe can contain concentrations of anything, which is what happened in this case.

Ethylene glycol can cause a profound high anion gap metabolic acidosis, and we'll explain the science, chemistry and physiology behind that in this episode.

Burn pits are a waste management tool for armed forces overseas. However, the nature of waste today is different than half a century ago. The smoke, fumes, and particulate matter that have been observed emanating from these pits contain a heterogeneous variety of materials. Exact exposure levels are not known in veterans, however many of these materials are known to be linked to long term health effects and some have been classified and recognized as carcinogens via retrospective analysis in humans and laboratory experiments. The particulate matter produced from these burn pits can also deposit into the earth and during weather events such as dust storms, can circulate the particles to local inhabitants, potentially causing health effects for them, years later.  Recognizing these long term health effects will enable people to not make these mistakes again, and to help those who have been exposed.
