Learning About Alcohol and Drug-Related Birth Defects

The week of May 14 is Alcohol and Drug-Related Birth Defects Awareness Week. According to the National Council on Alcoholism and Drug Dependence:

About 20% of pregnant women smoke cigarettes, 12% drink alcohol and 6% use an illicit drug at least once during pregnancy. These numbers are very alarming. If only people knew the dangers of their decisions, perhaps we would be looking at something more acceptable in those numbers.

So what are some of the dangers posed by these substances to a developing fetus?

Effects of Tobacco Use

According to the Centers for Disease Control and Prevention, the fetus gets less oxygen when the mother smokes. Smoking during pregnancy is a risk factor for low birth weight, preterm birth, placenta problems, miscarriage, and sudden infant death syndrome (SIDS).

Effects of Alcohol Use

I have written about the effects of alcohol use during pregnancy before — in fact, it was the subject for the first article I wrote for this blog.

Alcohol easily passes through the placenta, so when a pregnant woman drinks, so does her fetus. Continue reading

STD Awareness: The Surprising Sexual Transmission of Non-STDs

What is a sexually transmitted disease, or STD? If someone catches their partner’s cold during sex, is that cold an STD? According to the Office on Women’s Health, an STD is “an infection passed from one person to another person through sexual contact.” Unless the cold was passed through sexual contact, rather than mouth-to-mouth contact, it would not be considered an STD. Others say that, for an infection to be considered an STD, its sexual transmission must make it significantly more common in the population. So, a disease like the common cold would probably be just as common even if people never had sex.


MRSA, meningitis, and the virus that causes pinkeye can be transmitted sexually.


However, there are some infections, such as hepatitis C or bacterial vaginosis, whose status as official STDs is controversial. While researchers argue with one another over where to draw the line between an STD and a non-STD, let’s take a look at some bacteria and viruses that can be transmitted sexually, even though they’re not officially categorized as “STDs.”

MRSA: Methicillin-Resistant Staphylococcus aureus

You’ve probably heard of MRSA, which is pronounced “mersa” and stands for methicillin-resistant Staphylococcus aureus — a strain of bacteria that is resistant to every antibiotic in the penicillin family, as well as others. S. aureus, or “staph” for short, is the same bacteria responsible for TSS, or toxic shock syndrome, which has most infamously been associated with the use of highly absorbent tampons. But mostly, staph is a common cause of skin infections, which could be deadly in the pre-antibiotic era, but these days usually don’t raise too many eyebrows.

Unfortunately, with the emergence of MRSA, which is difficult to treat with the usual drugs, we might once again have to worry about minor skin infections blossoming into life-threatening conditions. Additionally, MRSA has found a way to hop from person to person via sexual contact, and sexually transmitted MRSA has been documented in both heterosexual and MSM (men who have sex with men) populations. Untreated, it can lead to a form of gangrene in which tissue blackens as it dies. Continue reading
