Over 90 Percent of What Planned Parenthood Does, Part 24: Miscarriage Management and Counseling

Welcome to the latest installment of “Over 90 Percent of What Planned Parenthood Does,” a series on Planned Parenthood Advocates of Arizona’s blog that highlights Planned Parenthood’s diverse array of services — the ones Jon Kyl never knew about.

holding handsMiscarriage. It’s a common occurrence — at least 10 to 15 percent of all pregnancies end this way — but one that is not often spoken about. When carrying a wanted pregnancy, its sudden loss can trigger a range of emotions. During this time, Planned Parenthood can help.


There is no “right” or “wrong” way to feel after having a miscarriage.


What Is Miscarriage?

When a pregnancy ends before it has reached the 20-week mark, a miscarriage has occurred; most miscarriages occur within the first eight weeks of pregnancy. Pregnancy loss after the 20-week mark is called stillbirth, and while it isn’t as common as miscarriage, stillbirth occurs in 1 out of 160 pregnancies.

Signs of a miscarriage include vaginal bleeding or spotting, severe abdominal pain or cramping, pain or pressure in the lower back, or a change in vaginal discharge. These symptoms aren’t specific to miscarriage — they could indicate other problems, so visit a health-care provider if you experience them during your pregnancy.

After a miscarriage, you might have pregnancy-related hormones circulating in your body for one or two months. Your period will most likely return within 4 to 6 weeks. While you may be physically ready to get pregnant again after you’ve had a normal period, you might want to consult with a health-care provider about the need for medical tests. You also might need to think about when you will be emotionally ready to try for another pregnancy. Continue reading

What Do We Know About Herbal Remedies and Menstrual Cramps? (Spoiler Alert: Not Much.)

herbalWhen I was entering adulthood and suffering from severe menstrual cramps, I suffered without relief for far too long. And I am certainly not alone in this experience. The most common gynecological disorder is dysmenorrhea — painful menstrual cramps — which strikes an estimated 90 percent of reproductive-age females. Furthermore, around 40 percent of American women use some form of complementary and alternative medicine, or CAM. “CAM” is a catchall for approaches to health care that fall outside of the mainstream. Given the popularity of CAM and the ubiquity of dysmenorrhea, it was no surprise that I experienced painful cramps, nor was it shocking that I tried a few herbal remedies, which are a type of CAM.


“Natural” doesn’t necessarily mean safe or effective, so be critical.


During my second year of college, at the age of 19, a friend recommended a couple of herbal remedies to add to my cramp-fighting arsenal. I tried them, but it was difficult to know if they really worked. My pain varied so wildly cycle to cycle that I had no way of knowing if I was just having a “good month” when I initially tried these products. Although I thought they worked at first, after I had accumulated more menstrual cycles under my belt, I started to wonder if my cramps were really any less painful. On average, I still seemed to be missing just as much school and work as before — but I wasn’t sure.

The problem was that I never collected any before-and-after data — I didn’t spend years ranking the severity and duration of my cramps, or keeping track of the hours spent in bed away from school, work, or other obligations. Furthermore, my initial sense of optimism could have colored my perceptions. Since we can be tricked by our own expectations and biases, it is important to have access to quality evidence — gathered in large, methodologically powerful studies.

Raspberry leaf tea was the first herbal remedy I tried. It tasted OK, and the ritualistic nature of drinking a hot beverage from a steaming mug was soothing. But is there any actual evidence that raspberry leaf can help relieve the pain of dysmenorrhea? Although it’s been used therapeutically since at least the 1500s, the only human studies I can find for any gynecological condition examine its use during pregnancy or labor — not for treating menstrual cramps. The only claims for raspberry leaf’s efficacy in treating cramps come from biased sources, like the manufacturers themselves. It seems the tea I drank during my late teen years had word of mouth and marketing going for it, but not much else. Continue reading

STD Awareness: The History of Syphilis

syphilisHave you ever heard that syphilis originated in the New World, and was imported to Europe by unwitting explorers? Some say it’s a fitting revenge for Europeans, who brought deadly diseases like smallpox and measles to the Americas. Others say that, while it’s an interesting hypothesis, it’s mostly speculation backed by some intriguing circumstantial evidence.

The predominating theory of syphilis’ origin is that it was transmitted from the Americas to Europe via sailors on Christopher Columbus’ ships — sailors who, in addition to other horrific acts, probably raped the natives of Hispaniola, from whom they could have contracted the infection. Historical records show that syphilis popped up in Europe in the last decade of the 1400s, coinciding with the return of Columbus and his crew — when Europe was deeply mired in war. With war came the far and wide travel of troops, who could have introduced the pathogen to prostitutes and other members of local populations.


In the era before antibiotics, syphilis was the world’s most feared sexually transmitted disease.


But we don’t know for certain that Columbus’ crew brought syphilis back from the West Indies in 1493. Some scholars point to ancient writings, from Biblical texts to Chinese records, that contain descriptions of diseases that are consistent with syphilis — though they might merely have described tuberculosis or leprosy. There are also pre-Columbian skeletons from Europe, Africa, and Asia that seem to exhibit evidence of syphilis infection — though diagnosing syphilis based on bone samples is problematic at best. Is it possible that syphilis had existed in the Old World all along, but didn’t become an epidemic until the wars of the Renaissance era allowed syphilis to conquer the continent?

Or perhaps the New World was home to a mild strain of the disease that mutated once it hit European soil. One team of researchers, studying Guyana’s remote Akwio tribe, discovered a disease that was a lot like syphilis, but was not an STD — it spread by skin-to-skin contact and infected about 1 in 20 children. Genetic analysis showed that it was caused by a bacteria that was closely related to the same bug that causes syphilis. Could Columbus’ men have picked up this transitional strain of bacteria and brought it back to Europe, where it mutated to evolve into the virulent pathogen we know today? Continue reading

STD Awareness: The Next Generation of Gardasil Is Coming!

noisemakersIt’s January, which means it’s time to festoon our surroundings with streamers, throw around the confetti, break out the noisemakers, and shout Happy Cervical Health Awareness Month!

And, in 2015, we have something huge to celebrate: Last month, the Food and Drug Administration (FDA) approved Gardasil 9, the next-generation HPV vaccine, which provides broader protection than the current version. Next month, the new and improved vaccine will start to be shipped to health care providers, and the Advisory Committee on Immunization Practices is expected to give the Centers for Disease Control and Prevention the green light to recommend the vaccine, after which insurance plans and the Vaccines for Children program should start covering it.


The newest version of Gardasil protects against the seven strains of human papillomavirus that together cause 90 percent of cervical cancers.


Why is this news so exciting for people who care about cervical health? Because, while the current version of Gardasil, which debuted in 2006, protects recipients from the two HPV strains that cause 70 percent of cervical cancers, Gardasil 9 will protect against seven strains of HPV that collectively cause 90 percent of cervical cancers. On top of that, both versions of Gardasil protect against the two HPV strains that are together responsible for 90 percent of genital warts.

Gardasil 9 has been shown to be highly effective in clinical studies, and it is safe to use, which means Gardasil just became an even more potent weapon against cancers caused by HPV. Not only that, but vaccination against HPV will also reduce the frequency of precancerous lesions, which are cellular abnormalities that can be treated before progressing into full-fledged cancer. Less pre-cancer means less time, money, and anxiety spent dealing with followup procedures after an abnormal Pap test, for example. Continue reading

STD Awareness: The Herpes Virus and Herpes Medications

herpes medicationOne of the most common sexually transmitted diseases (STDs) is herpes, which affects an estimated 1 out of 6 Americans between the ages of 14 and 49. Herpes is caused by a virus, and one reason that it’s so widespread is that the herpesvirus is ancient. Prehistoric, even — dinosaurs are thought to have been infected by herpesviruses! The Herpesviridae family is huge, with at least 100 members infecting mammals, birds, reptiles, bony fish, amphibians, and oysters.


Herpes drugs from the acyclovir family physically block herpes DNA from replicating — which is pretty amazing!


Humans can suffer from both oral herpes and genital herpes, which are caused by two types of the herpes simplex virus (HSV-1 and HSV-2). Recent genetic analysis reveals that the virus that causes cold sores, HSV-1, has been evolving with us since before we were Homo sapiens, diverging from the viruses that infected our common ancestors 6 million years ago. Interestingly, we didn’t acquire HSV-2 — which mostly causes genital herpes — until our Homo erectus ancestors caught it from early chimpanzees 1.6 million years ago, well before the emergence of modern Homo sapiens around 200,000 years ago.

Most people know what the virus doesgenital herpes can involve blisters, pain, and itching — but most people don’t know how the virus works. Luckily, scientists have uncovered a lot of the virus’ secrets — which has allowed them to develop some pretty effective drugs that we can use to foil herpes’ plans. Continue reading

STD Awareness: Three Sexually Transmitted Bacteria That Will Shock and Amaze You

It’s hard to appreciate a pubic louse as an intriguing creature in its own right. Not when an infestation with pubic lice is such a vexing experience. The same can be said for the germs that cause any number of human diseases. But, just as you might have marveled at the microorganisms you spied under the microscope in your high school biology class, the bacteria and other microbes that cause sexually transmitted diseases (STDs) can be fascinating, strictly as scientific subjects.

Let’s look at a few of these fascinating bacteria!

Treponema pallidum: the bacteria that cause syphilis

Before the age of antibiotics, syphilis was the most feared STD out there. Untreated, it can cause serious, sometimes fatal, damage to the body, and can also spread to a fetus during pregnancy. But did you know that earlier versions of syphilis might have been even worse?

Written records of syphilis date back to 1495 when it seemed to appear in Europe for the first time. According to a 1519 description, it caused

Boils that stood out like Acorns, from whence issued such filthy stinking Matter, that whosoever came within the Scent, believed himself infected. The Colour of these was of a dark Green and the very Aspect as shocking as the pain itself, which yet was as if the Sick had laid upon a fire.

Interestingly, such descriptions don’t match modern forms of syphilis, which suggests that it might have evolved into a less virulent form, possibly in response to selective pressure against symptoms that render the host sexually unappealing. Basically, that means that someone with boils emitting “filthy stinking Matter” might have trouble find sexual partners; the pustules of yore don’t seem to decorate the epidermis of contemporary sufferers, making them more likely to perpetuate milder forms of syphilis through sexual transmission.

We can’t hop into a time machine and take samples from European syphilitics in 1495, but some biologists believe that it took about 50 years for evolution to work its mojo on the disease, giving rise to the milder Syphilis 2.0 in the mid-1500s. Continue reading

STD Awareness: Which STDs Are Reportable?

doc-clipboardYou might have heard the phrase “reportable disease” before, but what does it mean? A reportable disease is considered to be important enough for health professionals to track on a societal level. When a health care provider diagnoses a patient with a reportable disease, he or she must notify certain agencies of the occurrence of a new case of this disease.


The reporting process is confidential and allows health workers to reduce the spread of STDs.


Every state has its own list of reportable diseases. For example, in Arizona, a health care provider must report new cases of chlamydia and gonorrhea within five days, and must report new cases of chancroid, HIV, and syphilis within 30 days. Additionally, in the case of syphilis, they must investigate the possibility of a syphilis outbreak. State health departments will report their stats to the Centers for Disease Control and Prevention (CDC), which tracks disease on a national scale. STDs that the CDC keeps track of are:

Does the fact that all these diseases are tracked and reported mean the government keeps a list of everyone with a reportable disease? No! Continue reading
